But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio. A p value of Results: A total of 60 participants were included. The median age was 44 years [36-55] and median duration of TFV therapy was 17.5 months [11.7-25.7]. The prevalence of reduced eGFR (Conclusion: Kidney function was impaired in some patients receiving TFV for CHB. It should be monitored, particularly after 36 months and for those receiving TDF prodrug.展开更多

In low- and middle-income countries such as the Congo, access to dialysis is low and inequitable. The prevention of CKD involves raising awareness among patients at risk, such as those suffering from arterial hypertension (AH), by improving their knowledge of CKD. The objectives of our work were to determine the level of knowledge about CKD among hypertensive patients and to identify the factors associated with a low level of knowledge. Methodology: We conducted a 3-month descriptive and analytical cross-sectional study from 1 August to 30 October 2023 in 3 large public hospitals in Brazzaville (capital of the Republic of Congo). We included: hypertensive patients aged 18 and over who had freely consented to participate in our study and were able to answer the questions on the survey form. Patients with known hypertension who had been followed for less than 3 years and those with known chronic renal failure were not included. Results: The mean age was 58.4 ± 14.4 years (29 - 88 years). There were 121 men and 150 women (sex ratio = 0.8). All the patients were educated;37.2% with a higher level of education and 13.6% with primary education. 24 patients (9%) had a good level of knowledge about CKD and 153 (56%) had poor knowledge. A good level of knowledge was associated with the duration of hypertension, intellectual level and the existence of associated heart disease. Conclusion: Our study reveals a significant lack of knowledge about chronic kidney disease among hypertensive patients in Brazzaville.展开更多

Randomized controlled trials(RCTs) regarding the comparison of CHI-WM combination therapy and WM monotherapy were included. Literature search, risk-of-bias assessment, and data extraction were conducted by 2 reviewers independently. NMA was performed by Stata 14.0, R 4.0.4 software, and the latest risk of bias assessment tool 2(RoB 2).Results: A total of 53 RCTs were finally included, involving 4445 participants and 16 CHIs. RoB 2 showed that 2 of these studies had a high risk of bias. Tianqi injection(TQ) + WM was the most effective in reducing serum creatinine(Scr) level. Xingding injection(XD) + WM was the most effective in reducing blood urea nitrogen(BUN) and cystatin C(Cys C) levels. Guhong injection(GH) + WM had the highest endogenous creatinine clearance rate(Ccr). Shuxuetong injection(SXT) + WM was the most effective in improving the clinical effective rate. Danhong injection(DH) + WM resulted in the lowest 24-h urinary protein quantity(24 h-UPQ), while Danshen injection(DS) + WM led to the lowest blood uric acid(UA)level. Shenfu injection(SF) + WM was the most effective in increasing hemoglobin(Hb) level.Conclusion: CHIs-WM combination therapy is more effective than WM monotherapy in treating CRF.Considering all of the indicators, SK + WM may be the optimal treatment option for improving renal function in patients with CRF.展开更多

The objective of this study was to determine the frequency, causes and main aggravating factors of chronic renal failure in the medical department of the hospital of Sikasso. Materials and Methods: This was a cross-sectional, retrospective, descriptive study conducted in the medical department of the Sikasso hospital from January 1, 2021 to November 30, 2022. It covered all the records of patients with chronic renal failure hospitalized in the department during this period. The MDRD formula was used to estimate the glomerular filtration rate. The KDIGO 2012 classification was used to stage CKD. Results: Of 820 patient records reviewed, we retained 197 records. The mean age of our patients was 42.25 ± 10 years. The male sex represented 114 (57.9%). The socio-economic level was considered low and precarious in 79.8% of cases. The frequency of chronic renal failure was 24%. The reason for hospitalization was mostly hyper creatinine > 185 μmol/l (92.4%). Herbal medicine was reported in 103 cases (52.3%). Medical history was hypertension 101 cases (51.3%), undocumented gastro duodenal ulcer (UGD) 14 cases (7.6%), hypertension and diabetes 11 cases (5.1%), diabetes 8 cases (4%), lower limb edema 9 cases (4.6%). Hypocalcemia was 147 cases (75.6%) with hyper phosphoremia was 153 cases (77.7%). Hemoglobin level was: <6 g/dl, 44 cases (22.3%);between 6 - 8 g/dl, 77 cases (39.1%), from 8 - 10 g/dl, 54 cases (27.4%). The etiologies of CKD were vascular nephropathy 106 cases (53.8%), interstitial nephropathy, 44 cases (22.3%), glomerular nephropathy, 33 cases (16.8%), diabetic nephropathy, 12 cases (6.1%) and polycystic kidney disease 2 (1%). CKD was classified as stage 5, 171 cases (86.8%), stage 4, 11 cases (5.6%), stage 3, 13 cases (6.6%) and stage 2, 2 cases (1%.) Dialysis was performed in 1095 (5.3%) of our patients. All these patients started dialysis with a central line. Conclusion: This study reveals the high prevalence of chronic renal failure in the department and above all the late diagnosis at very advanced stages. This imposes policies of prevention and effective management of the responsible diseases.展开更多

Cardiorenal syndrome is the condition in which these two organs negatively affect each other, therefore an accurate evaluation of renal function in the clinical setting of CHF is essential. This review aims to revise the parameters currently used to evaluate renal dysfunction in CHF with particular reference to the usefulness and the limitations of biomarkers in evaluating glomerular dysfunction and tubular damage. Moreover, it is reported the possible utility of renal arterial resistance index(a parameter associated with abnormalities in renal vascular bed) for a better assesment of kidney disfunction.展开更多

Their levels were 24. 40± 10. 30 μg/L, 26. 99±5.77 μg/L,38. 81±6. 28 μg/L, 79. 74± 18. 76 μg/L, respectively. The level of urinary FPA in renal insufficiency function group was significantly higher than those of the con-trol group and normal renal function group (P<0.01). The patients with uremia presented dramatically higher level of urinary FPA than those in the renal insufficiency group (P<0.01). A positive correlation was found between the level of urinary FPA and the blood creatine (r= 0. 9120, P<0. 01 ). It was suggested that a hypercoagulable state existed in the patients with chronic nephritis with renal failure, in which the severity was closely related with the occurrence and development of the disease. The urinary FPA could serve as a good indicator for renal function.展开更多

This review discusses cardiac surgery in the CKD population and considers ostoperative acute renal failure (ARF). CKD patients have worse outcomes following coronary artery bypass grafting (CABG) and cardiac valvular surgery than the general population. However,surgical revascularization is an effective treatment for coronary artery disease (CAD) in this population and may be associated with improved survival over percutaneous intervention (PCI) in advanced CKD. Cardiac surgery in the CKD population requires careful perioperative planning and management. Acute renal failure (ARF) is a serious complication following cardiac surgery, occurring in 1 to 8% of cases. Management of postoperative ARF is largely supportive and emphasis is placed on preoperative risk stratification and prevention.展开更多

The objectives of this study were to determine the factors associated with late nephrology case management and to describe the evolution of patients depending on the time of care nephrology. Material and Methods: It was a 5-year prospective study, observational type, going from January 1st, 2010 to December 31th, 2014. We studied all the patients hospitalized with chronic renal failure with dialysis or not and we excluded the patients hospitalized for acute renal failure. Results: The study population includes 307 men (53.4%) and 268 women (46.6%) with a sex ratio of 1.14. Age population ranged between 15 and 85 years old with a mean of 44.4 ± 16.20 years old. Their profession was distributed as follows: 220 housewives (38.3%), 181 workers (31.5%), 104 civil servants (18.1%), 56 students (9.7%) and 14 unemployed (2.4%). Patients came from all regions of the country: Conakry: 389 patients (67.6%);Lower Guinea: 82 (14.3%);Middle-Guinea: 57 (9.9%);Upper Guinea: 31 (5.4%);Guinea Forest Region: 16 (2.8%). In this study population, 48 patients were admitted in emergency (8.3%);105 were scheduled (18.3%) and 422 were referred to the nephrology department (73.4%). Reasons for the emergency admission were acute pulmonary edema in 21 patients (43.7%), decompensated anemia in 13 patients (27.1%), loss of consciousness in 9 patients (18.7%) and malignant hypertension in 5 patients (10.4%). The reference patterns was uremic syndrome in 312 patients (54.3%), followed by high blood pressure in 247 patients (42.9%), an edematous syndrome in 234 patients (40.7%), oligoanuria in 222 patients (38.6%), morphological abnormalities on the renal ultrasound in 4 patients (0.7%). The functional symptoms were vomiting in 379 patients (65.9%), followed by dyspnea in 290 patients (50.4%), headaches in 287 patients (49.9%). Among them, 121 patients could handle alone, 431 were borne by their families and 23 were indigent;181 patients had consulted before 1 month of the beginning of the signs, 238 between 1 and 2 months and 156 after 2 months;48 were admitted in emergency, 105 were programmed by the Nephrology Department and 422 were referred to the other health structures of the country. Conclusion: Several factors contributed to the delay in treatment, among which: the low socioeconomic level, the delay of the reference of the patients, the long distance of the regions, the lack of Nephrology units in the country.展开更多

Anemia is one of its most common complications. Anemia increases the risk factor for cardiovascular mortality by 18% per gram of hemoglobin loss. <strong>Objectives:</strong> To determine the prevalence and characteristics of this severe anemia, to determine the indications for transfusion, the complications related to this anemia, the evolution and the prognosis of these patients. <strong>Materials and Methods:</strong> This was a descriptive study with retrospective data collection over 18 months (January 1, 2017 to June 30, 2018) that included hospitalized CRF patients. Were included, non-dialyzed chronic renal failure patients with Hb ≤ 5 g/dl hospitalized during the said period. Not included were chronic renal failure patients with an Hb level ≥ 5 g/dl, those followed up and/or hospitalized outside the study period. <strong>Results:</strong> Among 1176 patients, 26 had severe anemia (Hb level ≤ 5 g/dl) on CRF, a prevalence of 2.21%. The mean age was 40 years ± 32.62 with extremes of 15 and 67 years. Seventeen women and 9 men. The etiology of chronic renal failure (CRF) was hypertensive vascular nephropathy in 50% of cases. CRF was end-stage in 18 patients (69.2%). The mean hemoglobin level was 4.10 g/dl ± 0.64 with extremes of 2 and 5 g/dl. The anemia was microcytic hypochromic in 50% and aregenerative (96.2%). The main symptoms were asthenia in 20 cases (76.9%), dizziness in 20 cases (76.9%), exertional dyspnea in 19 cases (73.1%). Signs of cardiac decompensation (n = 12) were jugular turgor 10 cases (38.5%), hepato-jugular reflux 06 cases (23.1%), mitral insufficiency murmur 06 cases (23.1%). The main complication was left ventricular hypertrophy 17 cases (77.3%). There was no correlation between anemia and sex (p = 0.291), age (p = 0.778), malaria (p = 0.158), etiology of CRF (p = 0.26). The evolution after treatment of anemia was favorable in 19 patients (73.1%), unfavorable in 02 patients (7.7%) and 05 deaths (19.2%). The deaths were of cardiovascular cause: left ventricular insufficiency 04 cases, stroke 01 case. <strong>Conclusion:</strong> Anemia is frequent in patients with chronic renal failure and remains an important risk factor for cardiovascular disease and poor general condition.展开更多

Methods: Eighty -three patients with CCI were randomly divided into YXQNG and nimodipine (ND) groups, the score of vertigo and the change in cerebral blood velocity before and after treatment were observed. And in the animal experiment, the authors adopted bilateral ligation of cervical carotid communis artery to establish CCI rat models in order to observe the effect of YXQNG and ND on incubation period of vertigo in rats and on memory performance. Results: After clinical treatment, the vertigo score of YXQNG group was 2.34, and that of the ND group was 4.18, the comparison between the two groups showed that the difference was significant ( P < 0.05 ). After treatment, the middle cerebral artery mean velocity (MCA Vm) of YXQNG group was 64.78 cm/s, vertebral artery mean velocity (VA Vm) was 29.78 cm/s, while that of ND group was 60.34 cm/s and 23.23 cm/s respectively, the comparison between these two groups showing statistical significance and the difference being obvious ( P <0.05). Experimental study showed that the rats in the model group after 12 weeks learning and memory were markedly lowered, the vertigo incubation period significantly lengthened, and compared with that of the model group, learning and memory of the YXQNG group was markedly improved and vertigo incubation period shortened, with the difference from that of the ND group insignificant, P >0.05. Conclusion: YXQNG could effectively improve CCI patients’ vertigo and other clinical symptoms and increase the cerebral blood flow, lessen the vertigo incubation of model group rats, elevate model group rats’ memory performance.展开更多

Groups were labeled as follows: 1a: normal renal function, H pylori negative (n = 12), 1b: normal renal function,H pylori positive (n = 11), 2a: CRF, H pylori negative (n = 10), 2b: CRF, H pylori positive (n = 11). Upper gastrointestinal endoscopy was done in all the patients involved in the study. During endoscopical investigation,antral biopsy specimens were taken from each patient.In order to evaluate the cell apoptosis and proliferation in gastric epithelial cells, Bax and proliferating cell nuclear antigen (PCNA) labeling indexes (LI) were assessed with immunohistochemical staining method.RESULTS: For groups 1a, 1b, 2a, and 2b, mean Bax LI was identified as 34.4±13.7, 44.1±16.5, 46.3±20.5,60.7±13.8, respectively and mean PCNA LI was identified as 36.2±17.2, 53.6±25.6, 59.5±25.6, 67.2±22,respectively. When the one-way ANOVA test was applied,statistically significant differences were detected between the groups for both Bax LI (P = 0.004 ＜0.01) and PCNA LI (P = 0.009 ＜0.01). When groups were compared further in terms of Bax LI and PCNA LI with Tukey's HSD test for multiple pairwise comparisons, statistically significant difference was observed only between groups 1a and 2b (P = 0.006 ＜0.01).CONCLUSION: In gastric epithelial cells, expression of both the pre-apoptotic protein Bax and the proliferation marker PCNA increase with H pylori infection. This increase is more evident in patients with uremia. These findings suggest that uremia accelerates apoptosis and proliferation in gastric epithelial cells.展开更多

文摘Pain is a common complaint among patients seeking medical care.If left un-treated,pain can become chronic,significantly affecting patients’quality of life.An accurate diagnosis of the underlying cause of pain is crucial for effective treatment.Chronic venous insufficiency(CVI)is frequently overlooked by pain physicians.Moreover,many pain physicians lack sufficient knowledge about CVI.CVI is a common condition resulting from malfunctioning or damaged valves in lower limb veins.Symptoms of CVI,ranging from mild to severe,include pain,heaviness,fatigue,itching,swelling,skin color changes,and ulcers in the lower limbs.Recently,it has become more widely known that these symptoms can be attributed to CVI.Even slight or mild CVI can cause related symptoms.Pain physicians primarily consider neuromusculoskeletal disorders when assessing patients with leg pain,and often neglect the possibility of CVI.In clinical practice,when pain physicians encounter patients with unresolved leg pain,they must assess whether the patients exhibit symptoms of CVI and conduct tests to differ-entiate CVI from other potential causes.
文摘Background: Tenofovir (TFV) is widely used to treat patients with hepatitis B virus (HBV) infection. But kidney abnormalities are the main concern using this drug. Few studies have described the renal impairment due to the TFV in chronic hepatitis B (CHB) in Sub-Saharan Africa. The objective was to evaluate factors associated with renal impairment observed in patients on TFV for CHB. Method: It was a hospital based cross sectional prospective study carried out from June 2023 to July 2023 in Yaoundé (Cameroon) and included any patient treated with TFV for CHB during at least a period of 6 months. For each participant, we collected in the medical report socio-demographic data, clinical data, baseline creatinine, treatment information (type of TFV which was Disoproxil Fumarate (TDF) or Alafenamide (TAF), duration). Then, we collected blood samples to measure serum creatinine and phosphate levels and urine dipstick analysis. Factors associated with renal impairment were assessed with the Odds Ratio. A p value of Results: A total of 60 participants were included. The median age was 44 years [36-55] and median duration of TFV therapy was 17.5 months [11.7-25.7]. The prevalence of reduced eGFR (Conclusion: Kidney function was impaired in some patients receiving TFV for CHB. It should be monitored, particularly after 36 months and for those receiving TDF prodrug.
文摘Background and Objectives: Chronic kidney disease (CKD) is now a global public health problem. In low- and middle-income countries such as the Congo, access to dialysis is low and inequitable. The prevention of CKD involves raising awareness among patients at risk, such as those suffering from arterial hypertension (AH), by improving their knowledge of CKD. The objectives of our work were to determine the level of knowledge about CKD among hypertensive patients and to identify the factors associated with a low level of knowledge. Methodology: We conducted a 3-month descriptive and analytical cross-sectional study from 1 August to 30 October 2023 in 3 large public hospitals in Brazzaville (capital of the Republic of Congo). We included: hypertensive patients aged 18 and over who had freely consented to participate in our study and were able to answer the questions on the survey form. Patients with known hypertension who had been followed for less than 3 years and those with known chronic renal failure were not included. Results: The mean age was 58.4 ± 14.4 years (29 - 88 years). There were 121 men and 150 women (sex ratio = 0.8). All the patients were educated;37.2% with a higher level of education and 13.6% with primary education. 24 patients (9%) had a good level of knowledge about CKD and 153 (56%) had poor knowledge. A good level of knowledge was associated with the duration of hypertension, intellectual level and the existence of associated heart disease. Conclusion: Our study reveals a significant lack of knowledge about chronic kidney disease among hypertensive patients in Brazzaville.

文摘Objective: To conduct a systematic review and network meta-analysis(NMA) for the comparison of the efficacy and safety of Chinese herbal injection(CHI) combined with Western medicine(WM) and WM monotherapy for chronic renal failure(CRF).Methods: Eight databases were searched from inception to August 30, 2022. Randomized controlled trials(RCTs) regarding the comparison of CHI-WM combination therapy and WM monotherapy were included. Literature search, risk-of-bias assessment, and data extraction were conducted by 2 reviewers independently. NMA was performed by Stata 14.0, R 4.0.4 software, and the latest risk of bias assessment tool 2(RoB 2).Results: A total of 53 RCTs were finally included, involving 4445 participants and 16 CHIs. RoB 2 showed that 2 of these studies had a high risk of bias. Tianqi injection(TQ) + WM was the most effective in reducing serum creatinine(Scr) level. Xingding injection(XD) + WM was the most effective in reducing blood urea nitrogen(BUN) and cystatin C(Cys C) levels. Guhong injection(GH) + WM had the highest endogenous creatinine clearance rate(Ccr). Shuxuetong injection(SXT) + WM was the most effective in improving the clinical effective rate. Danhong injection(DH) + WM resulted in the lowest 24-h urinary protein quantity(24 h-UPQ), while Danshen injection(DS) + WM led to the lowest blood uric acid(UA)level. Shenfu injection(SF) + WM was the most effective in increasing hemoglobin(Hb) level.Conclusion: CHIs-WM combination therapy is more effective than WM monotherapy in treating CRF.Considering all of the indicators, SK + WM may be the optimal treatment option for improving renal function in patients with CRF.
文摘Introduction: Chronic renal failure is a real public health problem because of its prevalence, the cost of its management and the high morbidity and mortality rate associated with it. The objective of this study was to determine the frequency, causes and main aggravating factors of chronic renal failure in the medical department of the hospital of Sikasso. Materials and Methods: This was a cross-sectional, retrospective, descriptive study conducted in the medical department of the Sikasso hospital from January 1, 2021 to November 30, 2022. It covered all the records of patients with chronic renal failure hospitalized in the department during this period. The MDRD formula was used to estimate the glomerular filtration rate. The KDIGO 2012 classification was used to stage CKD. Results: Of 820 patient records reviewed, we retained 197 records. The mean age of our patients was 42.25 ± 10 years. The male sex represented 114 (57.9%). The socio-economic level was considered low and precarious in 79.8% of cases. The frequency of chronic renal failure was 24%. The reason for hospitalization was mostly hyper creatinine > 185 μmol/l (92.4%). Herbal medicine was reported in 103 cases (52.3%). Medical history was hypertension 101 cases (51.3%), undocumented gastro duodenal ulcer (UGD) 14 cases (7.6%), hypertension and diabetes 11 cases (5.1%), diabetes 8 cases (4%), lower limb edema 9 cases (4.6%). Hypocalcemia was 147 cases (75.6%) with hyper phosphoremia was 153 cases (77.7%). Hemoglobin level was: <6 g/dl, 44 cases (22.3%);between 6 - 8 g/dl, 77 cases (39.1%), from 8 - 10 g/dl, 54 cases (27.4%). The etiologies of CKD were vascular nephropathy 106 cases (53.8%), interstitial nephropathy, 44 cases (22.3%), glomerular nephropathy, 33 cases (16.8%), diabetic nephropathy, 12 cases (6.1%) and polycystic kidney disease 2 (1%). CKD was classified as stage 5, 171 cases (86.8%), stage 4, 11 cases (5.6%), stage 3, 13 cases (6.6%) and stage 2, 2 cases (1%.) Dialysis was performed in 1095 (5.3%) of our patients. All these patients started dialysis with a central line. Conclusion: This study reveals the high prevalence of chronic renal failure in the department and above all the late diagnosis at very advanced stages. This imposes policies of prevention and effective management of the responsible diseases.
文摘BACKGROUND Diabetic nephropathy(DN)is frequently seen in the development of diabetes mellitus,and its pathogenic factors are complicated.Its current treatment is controversial,and there is a lack of a relevant efficacy prediction model.AIM To determine the effects of paricalcitol combined with hemodiafiltration on bonemetabolism-related indexes in patients with DN and chronic renal failure(CRF),and to construct an efficacy prediction model.METHODS We retrospectively analyzed 422 patients with DN and CRF treated in Cangzhou Central Hospital between May 2020 and May 2022.We selected 94 patients who met the inclusion and exclusion criteria.Patients were assigned to a dialysis group(n=45)and a joint group(n=49)in relation to therapeutic regimen.The clinical efficacy of the two groups was compared after treatment.The changes in laboratory indexes after treatment were evaluated,and the two groups were compared for the incidence of adverse reactions.The predictive value of laboratory indexes on the clinical efficacy on patients was analyzed.RESULTS The dialysis group showed a notably worse improvement in clinical efficacy than the joint group(P=0.017).After treatment,the joint group showed notably lower serum levels of serum creatinine,uric acid(UA)and blood urea nitrogen(BUN)than the dialysis group(P<0.05).After treatment,the joint group had lower serum levels of phosphorus,procollagen type I amino-terminal propeptide(PINP)and intact parathyroid hormone than the dialysis group,but a higher calcium level(P<0.001).Both groups had a similar incidence of adverse reactions(P>0.05).According to least absolute shrinkage and selection operator regression analysis,UA,BUN,phosphorus and PINP were related to treatment efficacy.According to further comparison,the non-improvement group had higher risk scores than the improvement group(P<0.0001),and the area under the curve of the risk score in efficacy prediction was 0.945.CONCLUSION For treatment of CRF and DN,combined paricalcitol and hemodiafiltration can deliver higher clinical efficacy and improve the bone metabolism of patients,with good safety.
文摘BACKGROUND Recent studies on dialysis anticoagulation therapy in patients with renal failure have shown that Nafamostat mesylate,a broad-spectrum potent serine protease inhibitor,has strong anticoagulation and anti-fiber activity.AIM To evaluate the efficacy and safety of Nafamostat mesylate in patients with end-stage renal failure.METHODS Seventy-five patients with end-stage renal failure who received hemodialysis at our hospital between January 2020 and August 2021 were selected and divided into the observation group(Nafamostat mesylate for injection,n=33)and control group(heparin sodium injection,n=32).General patient data,indicators of clinical efficacy,dialyzer hemocoagulation parameters,coagulation function indices,and hemoglobin concentration and platelet count before and after treatment,and the occurrence of adverse reactions after treatment were compared between the two groups.RESULTS The two groups showed no significant differences in general patient data(P>0.05).The post-treatment effectiveness rate in the control group was lower than that in the observation group(P<0.05).The two groups showed no significant difference in the number of patients in grade I(P>0.05),while the number of patients in grade 0 was lower in the control group,and the number of patients in grades II and III was higher in the control group(P<0.05).The post-treatment prothrombin time,activated partial thromboplastin time,thrombin time,and international normalized ratio values in the control group were higher than those in the observation group,while the fibrinogen level in the control group was lower than that in the observation group(P<0.05).The two groups showed no significant difference in the platelet count and hemoglobin level before and after treatment(P>0.05).The total number of post-treatment adverse reactions in the observation group was lower than that in the control group(P<0.05).CONCLUSION Treatment of patients showing end-stage renal failure with Nafamostat mesylate can significantly improve therapeutic efficacy and has high safety and clinical value.
文摘BACKGROUND Heparin-induced thrombocytopenia(HIT)is a rare complication of heparin therapy,and is characterized by arteriovenous thrombosis and bleeding events.The incidence of HIT after percutaneous coronary intervention(PCI)in patients with myocardial infarction complicated with renal failure is rarely reported.CASE SUMMARY We report a 73-year-old man with acute myocardial infarction and renal failure who underwent hemodialysis and PCI,and developed a progressive decline in platelets and subcutaneous hemorrhage of both upper limbs after heparin treatment.In addition to a gradual decrease in platelets,the patient’s 4T's score was 7,and HIT antibody was positive,confirming the diagnosis of HIT.CONCLUSION Patients receiving heparin combined with antiplatelet therapy should be monitored closely,especially for their platelet count.In the case of thrombocytopenia,HIT should be highly suspected.When the diagnosis of HIT is confirmed,timely individualized treatment should be delivered.
文摘Chronic kidney disease and its worsening are recurring conditions in chronic heart failure(CHF) which are independently associated with poor patient outcome.The heart and kidney share many pathophysiological mechanisms which can determine dysfunction in each organ. Cardiorenal syndrome is the condition in which these two organs negatively affect each other, therefore an accurate evaluation of renal function in the clinical setting of CHF is essential. This review aims to revise the parameters currently used to evaluate renal dysfunction in CHF with particular reference to the usefulness and the limitations of biomarkers in evaluating glomerular dysfunction and tubular damage. Moreover, it is reported the possible utility of renal arterial resistance index(a parameter associated with abnormalities in renal vascular bed) for a better assesment of kidney disfunction.
文摘The level of urinary FPA was assayed by high per formance liquid chromatography (HPLC ) in 42 normal controls, 57 cases of chronic glomeru-lonephritis, including 24 with normal renal function, 12 with renal insufficiency and 21 with uremia. Their levels were 24. 40± 10. 30 μg/L, 26. 99±5.77 μg/L,38. 81±6. 28 μg/L, 79. 74± 18. 76 μg/L, respectively. The level of urinary FPA in renal insufficiency function group was significantly higher than those of the con-trol group and normal renal function group (P<0.01). The patients with uremia presented dramatically higher level of urinary FPA than those in the renal insufficiency group (P<0.01). A positive correlation was found between the level of urinary FPA and the blood creatine (r= 0. 9120, P<0. 01 ). It was suggested that a hypercoagulable state existed in the patients with chronic nephritis with renal failure, in which the severity was closely related with the occurrence and development of the disease. The urinary FPA could serve as a good indicator for renal function.
文摘BACKGROUND Secondary hyperparathyroidism,renal osteodystrophy,and cardiovascular adverse events can occur if long-term hyperphosphatemia is not corrected,leading to the adverse prognosis of patients with chronic renal failure.Besides the use of phosphorus binders,clinical control measures for hyperphosphatemia in these patients should also incorporate diet control.AIM To observe doctor-led intensive diet education effects on health-related quality of life in patients with chronic renal failure and hyperphosphatemia.METHODS We assessed 120 patients with hyperphosphatemia and chronic renal failure on hemodialysis admitted to our hospital(July 2018 to March 2020).The control group(n=60)was given routine nursing guidance,and the observation group(n=60)was given doctor-led intensive diet education.The changes in EQ-5D-3L scores,disease-related knowledge,and compliance scores before intervention and 3 and 6 mo after intervention in the two groups were recorded.The levels of serum parathyroid hormone(iPTH),calcium(Ca),phosphorus(P),calciumphosphorus product(Ca×P),serum creatinine(Scr),and blood urea nitrogen(BUN)before intervention and 3 and 6 mo after intervention in the two groups were assessed along with patient satisfaction.RESULTS There was no significant difference in blood iPTH,Ca,P,Ca×P,Scr,or BUN levels between the groups before intervention.After 3 and 6 mo of intervention,the blood iPTH,Ca,P,and Ca×P levels in the two groups decreased gradually(P<0.05),but there were no significant differences in Scr or BUN.The blood iPTH,Ca,P,and Ca×P levels in the observation group were lower than those in the control group(P<0.05).The satisfaction rate in the observation group after 3 mo was 93.33%and after 6,90.00%,which was high compared with the 80.00%and 71.67%,respectively,in the control group(P<0.05).There was no significant difference in EQ-5D-3L score between the two groups before intervention.After 3 and 6 mo of intervention,the visual analogue scale score of the two groups increased gradually(P<0.05);and the scores of action ability,self-care,daily activities,pain and discomfort,and anxiety and depression decreased gradually(P<0.05).The overall EQ-5D-3L score in the observation group was better than that in the control group(P<0.05).There was no significant difference in diseaserelated knowledge or compliance scores between the groups before intervention.After 3 and 6 mo of intervention,the scores of disease,diet,and medication knowledge and compliance in the two groups increased gradually(P<0.05).The scores of disease-related knowledge and compliance were higher in the observation group than in the control group(P<0.05).CONCLUSION Doctor-led intensive diet education can improve patient satisfaction and the quality of life in patients with chronic renal failure and hyperphosphatemia and promote low-phosphorus diet behavior.
文摘Objectives:?The aim of our work was to identify the etiologies of chronic renal failure in adolescent patients.?Patients and Methods:?This is a descriptive cross-sectional retrospective study that included adolescents aged 10 to 19 years hospitalized between January 2014 and December 2017 in the department of nephrology at the?University Hospital of Brazzaville. The CRF was defined according to the ANAES criteria by an estimated glomerular filtration rate less than 60 ml/min/?1.73?m2?of body surface.?Results:?Forty cases of CRF were collected, representing a prevalence of 4.9%. The average age was 16.32 ± 3.64 years and the sex ratio was 3. The most common mode of discovery was edematous syndrome 62.5%. The most common etiology was glomerular nephropathies 60%, hereditary nephropathies 25% and malformative uropathies in 15%. Ten patients (25%) had moderate CFR at admission, 62.5% had severe CRF, 12.5% had terminal CFR?and all of them died during the year.?Conclusion:?Epidemiological data CRF in adolescent patients in developing countries are scarce and limit treatment. Glomerular pathologies represent the most frequent etiology. Early treatment of chronic renal failure in childhood and multidisciplinary collaboration between pediatrician and nephrologist are necessary.
文摘Chronic kidney disease(CKD)in patients with liver cirrhosis has become a new frontier in hepatology.In recent years,a sharp increase in the diagnosis of CKD has been observed among patients with cirrhosis.The rising prevalence of risk factors,such as diabetes,hypertension and nonalcoholic fatty liver disease,appears to have contributed significantly to the high prevalence of CKD.Moreover,the diagnosis of CKD in cirrhosis is now based on a reduction in the estimated glomerular filtration rate of<60 mL/min over more than 3 mo.This definition has resulted in a better differentiation of CKD from acute kidney injury(AKI),leading to its greater recognition.It has also been noted that a significant proportion of AKI transforms into CKD in patients with decompensated cirrhosis.CKD in cirrhosis can be structural CKD due to kidney injury or functional CKD secondary to circulatory and neurohormonal imbalances.The available literature on combined cirrhosis-CKD is extremely limited,as most attempts to assess renal dysfunction in cirrhosis have so far concentrated on AKI.Due to problems related to glomerular filtration rate estimation in cirrhosis,the absence of reliable biomarkers of CKD and technical difficulties in performing renal biopsy in advanced cirrhosis,CKD in cirrhosis can present many challenges for clinicians.With combined hepatorenal dysfunctions,fluid mobilization becomes problematic,and there may be difficulties with drug tolerance,hemodialysis and decision-making regarding the need for liver vs simultaneous liver and kidney transplantation.This paper offers a thorough overview of the increasingly known CKD in patients with cirrhosis,with clinical consequences and difficulties occurring in the diagnosis and treatment of such patients.
文摘Cardiovascular disease is an important cause of mortality in the chronic kidney disease (CKD) population. This review discusses cardiac surgery in the CKD population and considers ostoperative acute renal failure (ARF). CKD patients have worse outcomes following coronary artery bypass grafting (CABG) and cardiac valvular surgery than the general population. However,surgical revascularization is an effective treatment for coronary artery disease (CAD) in this population and may be associated with improved survival over percutaneous intervention (PCI) in advanced CKD. Cardiac surgery in the CKD population requires careful perioperative planning and management. Acute renal failure (ARF) is a serious complication following cardiac surgery, occurring in 1 to 8% of cases. Management of postoperative ARF is largely supportive and emphasis is placed on preoperative risk stratification and prevention.
文摘Context and Object: Late nephrology case management for patients with chronic renal failure is consistently associated with high morbidity rate. The objectives of this study were to determine the factors associated with late nephrology case management and to describe the evolution of patients depending on the time of care nephrology. Material and Methods: It was a 5-year prospective study, observational type, going from January 1st, 2010 to December 31th, 2014. We studied all the patients hospitalized with chronic renal failure with dialysis or not and we excluded the patients hospitalized for acute renal failure. Results: The study population includes 307 men (53.4%) and 268 women (46.6%) with a sex ratio of 1.14. Age population ranged between 15 and 85 years old with a mean of 44.4 ± 16.20 years old. Their profession was distributed as follows: 220 housewives (38.3%), 181 workers (31.5%), 104 civil servants (18.1%), 56 students (9.7%) and 14 unemployed (2.4%). Patients came from all regions of the country: Conakry: 389 patients (67.6%);Lower Guinea: 82 (14.3%);Middle-Guinea: 57 (9.9%);Upper Guinea: 31 (5.4%);Guinea Forest Region: 16 (2.8%). In this study population, 48 patients were admitted in emergency (8.3%);105 were scheduled (18.3%) and 422 were referred to the nephrology department (73.4%). Reasons for the emergency admission were acute pulmonary edema in 21 patients (43.7%), decompensated anemia in 13 patients (27.1%), loss of consciousness in 9 patients (18.7%) and malignant hypertension in 5 patients (10.4%). The reference patterns was uremic syndrome in 312 patients (54.3%), followed by high blood pressure in 247 patients (42.9%), an edematous syndrome in 234 patients (40.7%), oligoanuria in 222 patients (38.6%), morphological abnormalities on the renal ultrasound in 4 patients (0.7%). The functional symptoms were vomiting in 379 patients (65.9%), followed by dyspnea in 290 patients (50.4%), headaches in 287 patients (49.9%). Among them, 121 patients could handle alone, 431 were borne by their families and 23 were indigent;181 patients had consulted before 1 month of the beginning of the signs, 238 between 1 and 2 months and 156 after 2 months;48 were admitted in emergency, 105 were programmed by the Nephrology Department and 422 were referred to the other health structures of the country. Conclusion: Several factors contributed to the delay in treatment, among which: the low socioeconomic level, the delay of the reference of the patients, the long distance of the regions, the lack of Nephrology units in the country.
文摘<strong>Introduction:</strong> Chronic renal failure (CRF) is defined as glomerular filtration rate (GFR) less than 60 ml/min/1.73m<sup>2</sup> for at least three (3) months. Anemia is one of its most common complications. Anemia increases the risk factor for cardiovascular mortality by 18% per gram of hemoglobin loss. <strong>Objectives:</strong> To determine the prevalence and characteristics of this severe anemia, to determine the indications for transfusion, the complications related to this anemia, the evolution and the prognosis of these patients. <strong>Materials and Methods:</strong> This was a descriptive study with retrospective data collection over 18 months (January 1, 2017 to June 30, 2018) that included hospitalized CRF patients. Were included, non-dialyzed chronic renal failure patients with Hb ≤ 5 g/dl hospitalized during the said period. Not included were chronic renal failure patients with an Hb level ≥ 5 g/dl, those followed up and/or hospitalized outside the study period. <strong>Results:</strong> Among 1176 patients, 26 had severe anemia (Hb level ≤ 5 g/dl) on CRF, a prevalence of 2.21%. The mean age was 40 years ± 32.62 with extremes of 15 and 67 years. Seventeen women and 9 men. The etiology of chronic renal failure (CRF) was hypertensive vascular nephropathy in 50% of cases. CRF was end-stage in 18 patients (69.2%). The mean hemoglobin level was 4.10 g/dl ± 0.64 with extremes of 2 and 5 g/dl. The anemia was microcytic hypochromic in 50% and aregenerative (96.2%). The main symptoms were asthenia in 20 cases (76.9%), dizziness in 20 cases (76.9%), exertional dyspnea in 19 cases (73.1%). Signs of cardiac decompensation (n = 12) were jugular turgor 10 cases (38.5%), hepato-jugular reflux 06 cases (23.1%), mitral insufficiency murmur 06 cases (23.1%). The main complication was left ventricular hypertrophy 17 cases (77.3%). There was no correlation between anemia and sex (p = 0.291), age (p = 0.778), malaria (p = 0.158), etiology of CRF (p = 0.26). The evolution after treatment of anemia was favorable in 19 patients (73.1%), unfavorable in 02 patients (7.7%) and 05 deaths (19.2%). The deaths were of cardiovascular cause: left ventricular insufficiency 04 cases, stroke 01 case. <strong>Conclusion:</strong> Anemia is frequent in patients with chronic renal failure and remains an important risk factor for cardiovascular disease and poor general condition.

文摘Objective: To observe the therapeutic effect of Yangxue Qingnao granule (养血清脑颗粒, YXQNG) in treating chronic cerebrovascular insufficiency (CCI) and its possible mechanism. Methods: Eighty -three patients with CCI were randomly divided into YXQNG and nimodipine (ND) groups, the score of vertigo and the change in cerebral blood velocity before and after treatment were observed. And in the animal experiment, the authors adopted bilateral ligation of cervical carotid communis artery to establish CCI rat models in order to observe the effect of YXQNG and ND on incubation period of vertigo in rats and on memory performance. Results: After clinical treatment, the vertigo score of YXQNG group was 2.34, and that of the ND group was 4.18, the comparison between the two groups showed that the difference was significant ( P < 0.05 ). After treatment, the middle cerebral artery mean velocity (MCA Vm) of YXQNG group was 64.78 cm/s, vertebral artery mean velocity (VA Vm) was 29.78 cm/s, while that of ND group was 60.34 cm/s and 23.23 cm/s respectively, the comparison between these two groups showing statistical significance and the difference being obvious ( P <0.05). Experimental study showed that the rats in the model group after 12 weeks learning and memory were markedly lowered, the vertigo incubation period significantly lengthened, and compared with that of the model group, learning and memory of the YXQNG group was markedly improved and vertigo incubation period shortened, with the difference from that of the ND group insignificant, P >0.05. Conclusion: YXQNG could effectively improve CCI patients’ vertigo and other clinical symptoms and increase the cerebral blood flow, lessen the vertigo incubation of model group rats, elevate model group rats’ memory performance.
文摘AIM: To evaluate the effects of Helicobacter pylori infection on gastric epithelial cell kinetics in patients with chronic renal failure (CRF).METHODS: Forty-four patients were enrolled in this study and divided into four groups with respect to their Helicobacter pylori (H pylori) and CRF status. Groups were labeled as follows: 1a: normal renal function, H pylori negative (n = 12), 1b: normal renal function,H pylori positive (n = 11), 2a: CRF, H pylori negative (n = 10), 2b: CRF, H pylori positive (n = 11). Upper gastrointestinal endoscopy was done in all the patients involved in the study. During endoscopical investigation,antral biopsy specimens were taken from each patient.In order to evaluate the cell apoptosis and proliferation in gastric epithelial cells, Bax and proliferating cell nuclear antigen (PCNA) labeling indexes (LI) were assessed with immunohistochemical staining method.RESULTS: For groups 1a, 1b, 2a, and 2b, mean Bax LI was identified as 34.4±13.7, 44.1±16.5, 46.3±20.5,60.7±13.8, respectively and mean PCNA LI was identified as 36.2±17.2, 53.6±25.6, 59.5±25.6, 67.2±22,respectively. When the one-way ANOVA test was applied,statistically significant differences were detected between the groups for both Bax LI (P = 0.004 ＜0.01) and PCNA LI (P = 0.009 ＜0.01). When groups were compared further in terms of Bax LI and PCNA LI with Tukey's HSD test for multiple pairwise comparisons, statistically significant difference was observed only between groups 1a and 2b (P = 0.006 ＜0.01).CONCLUSION: In gastric epithelial cells, expression of both the pre-apoptotic protein Bax and the proliferation marker PCNA increase with H pylori infection. This increase is more evident in patients with uremia. These findings suggest that uremia accelerates apoptosis and proliferation in gastric epithelial cells.
