Previous research showed reversible;acute afferent arteriolar vasculopathy and irreversible chronic interstitial fibrosis associated with CNI nephrotoxicity. In this case report we describe a patient, with minimal change disease, that had developed chronic and progressive renal disease while receiving therapeutic dose of Tacrolimus. His serum creatinine had reached 537 umol/L and his nephrotic state worsened. Kidney biopsy showed chronic interstitial nephritis. Tacrolimus was discontinued and he was treated with 1 mg/kg prednisone in addition to Mycophenolate mofetil (MMF) 1 g twice daily. By the 2<sup>nd</sup> month;serum creatinine returned to normal and by the 3<sup>rd</sup> month serum albumin too. After 1 month of therapy;the dose of Prednisone was tapered down gradually till 5 mg daily by the end of 3<sup>rd</sup> month. Moreover, the dose of MMF was reduced to 500 mg X2 by the end of 3<sup>rd</sup> month. After 2 years of follow up;he remained stable and without relapse of NS or renal failure. In conclusion, reversible renal disease, due to chronic interstitial nephritis can be induced by CNI which is amenable to treatment with Prednisone and MMF.展开更多

Although infection is typically ongoing when patients present with SAGN, in the case of deep-seated infections, the presence of infection may not be apparent. The aim of this study is to highlight the importance of renal biopsy when the diagnosis is not obvious. We present a case of staphylococcus associated glomerulonephritis in a patient treated with beta-lactam antibiotics for staphylococcus bacteraemia. A renal biopsy helped differentiate between interstitial nephritis and staphylococcus associated glomerulonephritis.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

ALN is considered to be a midpoint in the spectrum of upper urinary tract infection, a spectrum ranging from uncomplicated pyelonephritis to intrarenal abscess. This condition may be difficult to recognize due to the lack of specific symptoms and laboratory findings. Therefore the disease is probably underdiagnosed. Computed tomography scanning represents the diagnostic gold standard for ALN, but magnetic resonance imagine could be considered in order to limit irradiation. The diagnosis is relevant since initial intravenous antibiotic therapy and overall length of treatment should not be shorter than 3 wk. We review the literature and analyze the ALN clinical presentation starting from four cases with the aim to give to the clinicians the elements to suspect and recognize the ALN in children.展开更多

文摘BACKGROUND In this study,we retrospectively analysed macrophage infiltration and podocyte injury in three patients with diffuse proliferative lupus nephritis(LN)who un-derwent repeated renal biopsy.CASE SUMMARY Clinical data of three diffuse proliferative LN patients with different pathological characteristics(case 1 was LN IV-G(A),case 2 was LN IV-G(A)+V,and case 3 was LN IV-G(A)+thrombotic microangiopathy)were reviewed.All patients underwent repeated renal biopsies 6 mo later,and renal biopsy specimens were studied.Macrophage infiltration was assessed by CD68 expression detected by immunohistochemical staining,and an immunofluorescence assay was used to detect podocin expression to assess podocyte damage.After treatment,Case 1 changed to LN III-(A),Case 2 remained as type V LN lesions,and Case 3,which changed to LN IV-S(A),had the worst prognosis.We observed reduced macro-phage infiltration after therapy.However,two of the patients with active lesions after treatment still showed macrophage infiltration in the renal interstitium.Before treatment,the three patients showed discontinuous expression of podocin.Notably,the integrity of podocin was restored after treatment in Case 1.CONCLUSION It may be possible to reverse podocyte damage and decrease the infiltrating ma-crophages in LN patients through effective treatment.
文摘The clinical spectrum of immunoglobulin A vasculitis nephritis(IgAVN)ranges from the relatively common transitory microscopic hematuria and/or low-grade proteinuria to nephritic or nephrotic syndrome,rapidly progressive glomerulonephritis,or even renal failure.Clinical and experimental studies have shown a multifactor pathogenesis:Infection triggers,impaired glycosylation of IgA1,complement activation,Toll-like-receptor activation and B cell proliferation.This knowledge can identify IgAVN patients at a greater risk for adverse outcome and increase the evidence for treatment recommendations.
文摘Membranous lupus nephritis(MLN),class V,is a distinct LN characterized by immune complex deposition on subepithelial kidney biopsy.MLN is often associated with nephrotic syndrome.The histology of MLN is very similar to idiopathic(primary)membranous nephropathy(pMN).However,MLN usually has abundant mesa-glomerular deposits absent in primary membranous nephropathy.The clinical manifestations,management,and prognosis of MLN differ from other types of LN(type III,IV,or mixed type III/IV+V).Although immunosuppressive therapy is often necessary for MLN,the optimal treatment regimen is yet to be determined.This review summarizes the progress in the diagnosis and treatment of MLN and discusses the selection of immunosuppressants for MLN.
文摘BACKGROUND Complement overactivation is a major driver of lupus nephritis(LN).Impaired interactions of C-reactive protein(CRP)with complement factor H(CFH)have been shown as a pathogenic mechanism that contributes to the overactivation of complement in LN.However,genetic variations of neither CRP nor CFH show consistent influences on the risk of LN.AIM To examine whether genetic variations of CRP and CFH in combination can improve the risk stratification in Chinese population.METHODS We genotyped six CRP single nucleotide polymorphisms(SNPs)(rs1205,rs3093062,rs2794521,rs1800947,rs3093077,and rs1130864)and three CFH SNPs(rs482934,rs1061170,and rs1061147)in 270 LN patients and 303 healthy subjects.RESULTS No linkage was found among CRP and CFH SNPs,indicating lack of genetic interactions between the two genes.Moreover,CRP and CFH SNPs,neither individually nor in combination,are associated with the risk or clinical manifestations of LN.Given the unambiguous pathogenic roles of the two genes.CONCLUSION These findings suggest that the biological effects of most genetic variations of CRP and CFH on their expressions or activities are not sufficient to influence the disease course of LN.
文摘Calcineurin inhibitors (CNI) are potent immunosuppressive agents in prophylaxis against graft rejection and autoimmune diseases including primary glomerulopathies. Previous research showed reversible;acute afferent arteriolar vasculopathy and irreversible chronic interstitial fibrosis associated with CNI nephrotoxicity. In this case report we describe a patient, with minimal change disease, that had developed chronic and progressive renal disease while receiving therapeutic dose of Tacrolimus. His serum creatinine had reached 537 umol/L and his nephrotic state worsened. Kidney biopsy showed chronic interstitial nephritis. Tacrolimus was discontinued and he was treated with 1 mg/kg prednisone in addition to Mycophenolate mofetil (MMF) 1 g twice daily. By the 2<sup>nd</sup> month;serum creatinine returned to normal and by the 3<sup>rd</sup> month serum albumin too. After 1 month of therapy;the dose of Prednisone was tapered down gradually till 5 mg daily by the end of 3<sup>rd</sup> month. Moreover, the dose of MMF was reduced to 500 mg X2 by the end of 3<sup>rd</sup> month. After 2 years of follow up;he remained stable and without relapse of NS or renal failure. In conclusion, reversible renal disease, due to chronic interstitial nephritis can be induced by CNI which is amenable to treatment with Prednisone and MMF.

文摘Objective:To systematically evaluate the efficacy and safety of Nephritis Rehabilitation Tablet(NRT)combined with valsartan in treatment of chronic glomerulonephritis(CGN).Methods:Computer search databases such as CNKI,CBM,VIP,wanfang,Embase,PubMed and Cochrane library,and find all randomized controlled trials(RCTs)comparing NRT combined with valsartan versus valsartan in treatment of chronic glomerulonephritis.The search time limit is to build the database until October 2020.RCTs were screened according to the inclusion and exclusion criteria.After data extraction and quality assessment,the Cochrane risk of bias tool was used to evaluate the methodological quality of these studies.Meta-analysis was performed by Review Manager 5.2,and GRADE system for evidence quality evaluation.Results:We have identified a total of 24 eligible RCTs with 2082 participants and completed a meta-analysis based on these RCTs.The results of the meta-analysis showed that compared with valsartan,NRT combined with valsartan treatment showed effective curative effect in terms of effective treatment rate(OR=4.72;95%CI,3.67,6.08;P<0.00001),24h urine protein quantification(MD=-0.52;95%CI,-0.59,-0.44;P<0.00001),serum creatinine(Scr)(MD=-10.33;95%CI,-14.00,-6.66;P<0.00001),Systolic blood pressure(SBP)(MD=-11.42;95%CI,-17.67,-5.17;P=0.0003),Diastolic blood pressure(DBP)(MD=-6.28;95%CI,-9.14,-3.42;P<0.0001),Blood urine nitrogen(BUN)(MD=-0.02;95%CI,-0.41,0.37;P=0.93),plasma albumin(ALB)(MD=5.05;95%CI,4.27,5.84;P<0.00001),and adverse reactions(OR=0.93,95%CI,0.54,1.60;P=0.78).No serious adverse events were mentioned in these studies.And based on the results of the systematic review,the GRADE system recommended ranking method was used to evaluate the quality of evidence and the recommendation level.The results showed that the level of evidence was moderate and the recommendation intensity was weak recommendation.Conclusions:NRT combined with valsartan has a significant effect on the treatment of CGN,and the treatment effect is better than valsartan alone.There are no obvious adverse reactions during the treatment process.However,due to the generally low quality of the literature included in these studies,and the variability of the evaluation methods of each study,morelarge samples,multi-center,high-quality samples are still needed RCTs are further verified.
文摘Staphylococcus associated glomerulonephritis (SAGN) is an uncommon infection-related glomerulonephritis. Although infection is typically ongoing when patients present with SAGN, in the case of deep-seated infections, the presence of infection may not be apparent. The aim of this study is to highlight the importance of renal biopsy when the diagnosis is not obvious. We present a case of staphylococcus associated glomerulonephritis in a patient treated with beta-lactam antibiotics for staphylococcus bacteraemia. A renal biopsy helped differentiate between interstitial nephritis and staphylococcus associated glomerulonephritis.
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 Idiopathic membranous nephropathy(IMN)has a high incidence in the middleaged and elderly population,and poses a great threat to the physical and mental health and quality of life of patients.Nephritis Rehabilitation Tablets have many potential effects,such as clearing residual toxins,tumefying the kidney and spleen,replenishing qi,and nourishing yin,and have played an important role in the treatment of a variety of kidney diseases.AIM To investigate the efficacy and safety of Nephritis Rehabilitation Tablets combined with tacrolimus in the treatment of IMN.METHODS Eighty-four patients with IMN recruited from January 2017 to September 2020 were randomly divided into a study group(n=42)and a control group(n=42).On the basis of routine symptomatic treatment,both groups were treated with tacrolimus,and the study group was additionally treated with Nephritis Rehabilitation Tablets.Both groups were treated for 12 wk.The therapeutic effect,the levels of renal function indexes[serum creatinine(Scr),serum albumin,and 24-h urinary protein],urinary immunoglobulin(IgG4),membrane attack complex(C5b-9),and the incidence of adverse reactions were measured before and after 12 wk of treatment.RESULTS The total effective rate in the study group was significantly higher than that of the control group.Before treatment,there was no significant difference in Scr,serum albumin,or 24 h urinary protein between the two groups.After 12 wk of treatment,the levels of Scr and 24-h urinary protein in both groups were significantly lower and serum albumin was significantly higher than those before treatment(P<0.05),and the levels of Scr and 24-h urinary protein were significantly lower(P=0.003 and 0.000,respectively),and the level of serum albumin was significantly higher(P=0.00)in the study group than in the control group.Before treatment,there was no significant difference in urinary IgG4 and C5b-9 levels between the study group and the control group(P=0.336 and 0.438,respectively).After 12 wk of treatment,the levels of urinary IgG4 and C5b-9 in the two groups were lower than those before treatment,and the levels of urinary IgG4 and C5b-9 in the study group were significantly lower than those in the control group(P=0.000).There was no significant difference in the incidence of adverse reactions between the two groups(P=0.710).CONCLUSION Based on routine intervention,Nephritis Rehabilitation Tablets combined with tacrolimus in the treatment of IMN can effectively improve the renal function of patients and downregulate the expression of urinary IgG4 and C5b-9.In addition,they can improve the overall therapeutic effect while not increasing the risk of adverse reactions.
文摘BACKGROUND Purpura nephritis,also called Henoch-Schönlein purpura nephritis,is a systemic disease with small dead vasculitis as the main pathological change.AIM To observe the influence of transitional nursing activities on the compliance behaviors and disease knowledge of children with purpura nephritis.METHODS A total of 82 children with purpura nephritis were included and divided into a general nursing group(41 children)and transitional nursing group(41 children)using the envelope method.The general nursing group received routine nursing care,while the transitional nursing group received transitional nursing care.The behaviors,knowledge of the disease,and self-management ability of the two groups were evaluated after nursing care was provided.RESULTS The scores of four items(self-care ability,self-responsibility,health knowledge level,and self-concept)in the transitional nursing group were significantly higher than those in the general nursing group.CONCLUSION Transitional nursing can directly improve the disease knowledge level and selfmanagement ability of children with purpura nephritis and effectively reduce complications.
文摘BACKGROUND Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated condition that consisted of disorders that share particular clinical,serologic and pathologic properties.The common presentation of disease includes tumor-like swelling of involved organs and the histopathological findings are a lymphoplasmacytic infiltrate enriched with IgG4-positive plasma cells,and a variable degree of fibrosis that has a characteristic "storiform" pattern in biopsy specimens of tumorlike masses.Major presentations of this disease,which often affects more than one organ,include autoimmune pancreatitis,salivary gland disease (sialadenitis),orbital disease and retroperitoneal fibrosis.The steroid treatment is essential for the treatment of the disease however,other immunosuppressive drugs including cyclophosphamide or rituximab could be an option in resistant cases.CASE SUMMARY Herein,we reported a 34-year-old woman whom previously had diagnosed with asthma,rheumatoid arthritis and Sj?gren’s syndrome (SS) referred our nephrology department due to acute kidney failure development at the last rheumatology visit.After kidney biopsy she has been diagnosed with IgG4-RD and tubuluointerstitial nephritis.She had been accepted resistant to steroid,mycophenolate mofetil,methotrexate and azathioprine therapies due to receiving in last two years.She refused to receive cyclophosphamide due to potential gonadotoxicity of the drug.Thus,rituximab therapy was considered.She received 1000 mg infusion,15 d apart and 6 mo later it has been administered same protocol.After one year from the last rituximab dose serum creatinine decreased from 4.4 mg/dL to 1.6 mg/dL,erythrocyte sedimentation rate decreased from 109 mm/h to 13 mm/h [reference range (RR) 0-20],and Creactive protein decreased from 55.6 mg/L to 5 mg/L (RR 0–6).All pathologic lymph nodes and masses were also disappeared.CONCLUSION Patients with IgG4-RD usually misdiagnosed with rheumatologic diseases including systemic lupus erythematous or SS and also they were screened for the presence of malignancy.Rituximab could be an important treatment option in cases with steroid resistant tubulointerstitial nephritis in IgG4-RD.

文摘BACKGROUND Patients with lupus nephritis(LN)typically undergo long-term treatment with glucocorticoids(GCs)and immunosuppressants.There is a growing demand for optimal therapy with better remission results and fewer side effects.Sustained traditional Chinese medicine(TCM)might be quite valuable for multitarget therapy,reducing the total dosage of GCs and minimizing the side effects of immunosuppressants.AIM To evaluate whether Dan Bai Xiao Formula(DBXF)can reduce the exposure to GCs and cyclophosphamide(CYC)and to assess the efficacy and safety of DBXF for the resolution of proteinuria and hematuria in children with LN.METHODS A 24-wk pilot study was conducted at Beijing Children’s Hospital.Children with active LN were divided into either a TCM group or a control group.Children in the TCM group received DBXF combined with GCs and CYC,and the ones in the control group received GCs and CYC every 4 wk for 24 wk.The primary endpoints of this trial were urinary protein excretion of<150 mg/d and normal serum albumin concentration and renal function.RESULTS The trial included 78 children,of whom 38 received GCs and CYC treatment(control group)and the remaining 40 received DBXF combined with GCs and CYC treatment(TCM group).At week 24,the TCM group showed a better rate of complete remission(42.5%);however,there was no significant difference compared with the control group(31.5%,P>0.05).The urine red blood cell count and urine protein level were significantly lower in the TCM group than in the control group at weeks 4,12,and 24(P<0.05).Furthermore,patients in the TCM group had a lower proportion of methylprednisolone pulses than those in the control group(1.30±1.41 vs 3.05±2.02,P<0.0001).The ending GC dose was significantly lower in the TCM group than in the control group(P<0.001).Moreover,more hepatic function damage,gastrointestinal adverse effects,and hypertension were observed in the control group than in the TCM group(P<0.05).CONCLUSION The findings suggest that DBXF treatment is effective and safe as a supplementary therapy for LN and is superior to routine GC and CYC therapy.DBXF containing combination treatment possibly results in a faster resolution of proteinuria and hematuria,smoother GC reduction,fewer methylprednisolone pulses,and fewer adverse events.
文摘Acute lobar nephritis(ALN) is a localized non-liquefactive inflammatory renal bacterial infection, which typically involves one or more lobes. ALN is considered to be a midpoint in the spectrum of upper urinary tract infection, a spectrum ranging from uncomplicated pyelonephritis to intrarenal abscess. This condition may be difficult to recognize due to the lack of specific symptoms and laboratory findings. Therefore the disease is probably underdiagnosed. Computed tomography scanning represents the diagnostic gold standard for ALN, but magnetic resonance imagine could be considered in order to limit irradiation. The diagnosis is relevant since initial intravenous antibiotic therapy and overall length of treatment should not be shorter than 3 wk. We review the literature and analyze the ALN clinical presentation starting from four cases with the aim to give to the clinicians the elements to suspect and recognize the ALN in children.

文摘BACKGROUND Alport syndrome(ATS)is a rare hereditary disease caused by mutations in genes such as COL4A3,COL4A4,and COL4A5.ATS involves a spectrum of phenotypes ranging from isolated hematuria that is nonprogressive to progressive renal disease with extrarenal abnormalities.Although ATS can be combined with other diseases or syndromes,ATS combined with lupus nephritis has not been reported before.CASE SUMMARY A Chinese family with ATS was recruited for the current study.Clinical characteristics(including findings from renal biopsy)of ATS patients were collected from medical records,and potential causative genes were explored by whole-exome sequencing.A heterozygous substitution in intron 22 of COL4A3(NM_000091 c.2657-1G>A)was found in the patients,which was further confirmed by quantitative polymerase chain reaction.CONCLUSION Heterozygous substitution of a COL4A3 gene splice site was identified by wholeexome sequencing,revealing the molecular pathogenic basis of this disorder.In general,identification of pathogenic genes can help to fully understand the molecular mechanism of disease and facilitate precise treatment.
文摘BACKGROUND Downgrading target treatment and laparoscopic partial nephrectomy have become increasingly popular in patients with renal cell carcinomas.Rare as it is,pneumothorax is one of the most severe intraoperative complications which needs immediate recognition.On the other hand,as a rheumatological disease,lupus nephritis requires a long period of hormone therapy.Cases of pneumothorax in hormone-consuming renal cancer patients are even fewer.CASE SUMMARY A 39-year-old woman was admitted to our department to take a laparoscopic partial nephrectomy.The patient had a medical history of lupus nephritis and renal clear cell carcinoma with hormone and target treatment.Her blood oxygen saturation dropped to 92%during the operation,and pneumothorax was detected by ultrasound.O2 inhalation and lung dilation were performed.Her vital signs were monitored closely throughout the operation.The operation was accomplished,and she regained consciousness smoothly.A postoperative bedside chest X-ray was conducted after she was transferred to the urosurgery ward,while no evidence of further pneumothorax or lib injury was observed.CONCLUSION Pneumothorax is a severe complication in laparoscopic or robotic-assisted laparoscopic operations,especially in retroperitoneal ones.It is easily neglected unless the injury of the diaphragm is found.Low insufflation pressure and shorter operation time are necessary for patients with a history of long-term hormone consumption or chronic immune system disease.
