Patients were initially treated with iv GC(iv GC group). If no significant improvement in visual function was obtained, they then received OD surgery(OD group). The pre-versus post-treatment efficacies of either iv GC or OD in these patients were assessed using several indices, including visual acuity, intraocular pressure, ocular alignment, ocular motility, and exophthalmos. RESULTS: Nighty-one eyes had definite DON while 79 were considered to have highly suspected DON. In the iv GC group, 51 individuals(85.0%) eventually demonstrated normal vision, while 10 patients(16.7%) demonstrated a reduction in deviation(P<0.01), and 35 cases(58.3%) showed slight improvements in ocular motility(P<0.01). In OD group, visual acuity improved in 24 cases(96.0%, P<0.01) and all patients showed varying reductions of exophthalmos(mean: 4.35±1.13 mm, P<0.01). Eight cases(32.0%) experienced an 8-15 PD reduction of deviation and ocular motility improved in 12 cases(48.0%), while 3 patients(12.0%) developed new-onset strabismus with diplopia post-surgically(P<0.01). Patients were followed up at an average of 1.55±1.07 y. CONCLUSION: Both iv GC and OD show good therapeutic efficacy in the treatment of sight-threatening TAO. Thepresence of extremely poor eyesight(≥0.5 log MAR) was corrected in some patients with iv GC alone, thus sparing these patients from subsequent OD surgery. In patients who were refractory to steroids, subsequent OD surgery often provided satisfactory outcomes, however, new-onset strabismus with diplopia was observed in 12.0% of these cases.展开更多

Electronic databases were searched, and standard methodological guidance of Cochrane Handbook for Systematic Reviews of Interventions was used. The primary outcome was overall response, and secondary outcomes included the improvement and change in clinical activity score(CAS), and adverse events.RESULTS: Ten RCTs were included in the Meta-analysis. Low quality evidence(one trial) showed that participants receiving IVGC achieved significantly higher response compared to participants receiving placebo [risk ratio(RR) 7.50, 95% confidence interval(CI) 1.14 to 49.26]. Moderate quality evidence(four trials) support appreciable benefit of IVGC in response compared with oral glucocorticoids(OGC), with of RR being 1.51(95%CI 1.25 to 1.83). There was low quality evidence(one trial) compatible with appreciable benefit for IVGC plus orbital radiotherapy in response(RR 1.38, 95%CI 1.07 to 1.79), compared with OGC plus orbital radiotherapy. One IVGC versus rituximab trial provided moderate quality evidence suggesting that participants using IVGC achieved significantly lowerresponse compared to participants using rituximab(RR 0.70, 95%CI 0.50 to 0.98). One IVGC versus mycophenolate mofetil(MMF) trial provided moderate quality evidence suggesting that participants using IVGC achieved significantly lower response compared to participants using MMF(RR 0.74, 95%CI 0.63 to 0.88). Very low quality evidence(one trial) showed that participants with dysthyroid optic neuropathy(DON) receiving IVGC were more likely to achieve response compared to participants receiving orbital decompression(RR 3.33, 95%CI 0.51 to 21.89).CONCLUSION: The current evidence is moderate quality, which is sufficient to support IVGC to be as the first-line treatment for moderate-to-severe GO, and the use of rituximab or MMF to be the second-line treatment instead of IVGC. However, the evidence is very low quality, which is insufficient to support the use of IVGC or orbital decompression as the first-line treatment of DON.展开更多

The exact pathogenesis of CSC, however, still remains obscure. In this paper, we hypothesized that CSC may result from a response of choroidal vessels to an acute increase in the environmental light intensity leading to a focal leakage from the choroidal vessels.High levels of glucocorticoids, in our proposed model,may cause persistence rather than initiation of the focal leakage, probably by suppressing the synthesis of collagen and extracellular matrix components and inhibiting fibroblastic activity.展开更多

CAP is a leading cause of illness and death. This review aims to determine the efficacy and safety of glucocorticoids in the treatment of community-acquired pneumonia(CAP).DATA SOURCES: We searched randomized controlled trials(RCTs) from Pubmed, EMBASE, Cochrane Library, Chinese Journal Full-text Database, and Chinese Biomedical Literature Database to obtain the information by using steroids, glucocorticoids, cortisol, corticosteroids, community-acquired pneumonia and CAP as key words. The quality of RCTs was evaluated. A Meta-analysis was made using Rev Man 5.0 provided by the Cochrance Collaboration.RESULTS: Seven RCTs involving 944 patients were included in the meta-analysis. The mean length of hospital stay in glucocorticoids treatment group was significantly shorter than that in standard treatment group(WMD=–1.70, 95%CI 2.01–1.39, Z=10.81, P<0.00001). No statistically significant differences were found in the mortality rate(RR=0.77,95%CI 0.46–1.27, Z=1.03, P=0.30), the mean length of hospital stay in ICU(WMD=1.17, 95%CI 1.68–4.02, Z=0.81, P=0.42), the incidence of super infection(RR=1.32, 95%CI 0.66–2.63, Z=0.79, P=0.43), the incidence of hyperglycemia(RR=1.84, 95%CI 0.76–4.41, Z=1.36, P=0.17), the incidence of upper gastrointestinal bleeding(RR=1.98, 95%CI 0.37–10.59, Z=0.80, P=0.42) between the standard treatment group and the glucocorticoids treatment group.CONCLUSIONS: The use of glucocorticoids in patients with community-acquired pneumonia can significantly shorten the duration of illness and have a favorable safety profile. However, it could not reduce the overall mortality.展开更多

It is very important to understand the clinical features of this disease for doctors. <strong>Objective:</strong> To explore the clinical efficacy of glucocorticoids in the treatment of HSP in Tibetan children at high altitude, and to analyze the possible causes of HSP in children at high altitude. The risk factors of the disease provide a reference for the treatment of HSP in children in high altitude areas. <strong>Methods:</strong> Selecting January 2015 to November 2020, 88 children diagnosed with Henoch-Schonlein Purpura in the outpatient and inpatient departments of the People’s Hospital of Bomi County, Tibet Autonomous Region were the subjects of the study. Its gender, age of onset, season of onset, predisposing factors, allergy history, first symptoms, clinical manifestations, laboratory examinations, etc., perform retrospective analysis. <strong>Results: </strong>Among 88 children with allergic purpura, 55 were boys, accounting for 62.5%, and 33 were girls, accounting for 37.5%. Men have more cases than women. All have clinical manifestations of purpura of the skin, among which 35 cases have obvious triggers, of which the above there were 26 cases of respiratory infections, 6 cases of dietary factors, and 3 cases of contact with allergic substances. Simple skin type: 18 cases, accounting for 20.45%;Abdominal type: 6 cases, accounting for 6.82%;2 male cases, accounting for 33.33%;4 female cases, accounting for 66.67%;Articular type: 8 cases, accounting for 33.33%;Renal type: 2 cases, accounting for 2.27%;54 cases of mixed type, accounting for 61.36%. After glucocorticoids, the rashes disappeared, no any adverse reactions. <strong>Conclusion:</strong> Allergic purpura in children is more common in school-age children, and upper respiratory tract infection is the main predisposing factor. Skin purpura is the main clinical manifestation, often associated with lower extremity joint swelling and pain. There is no significant difference in the efficacy and course of the disease between intravenous and oral treatment. Therefore, clinicians should strictly grasp the indications of glucocorticoids to reduce the occurrence of complications.展开更多

Here, we aimed to explore the characteristics of glucocorticoids in participants with dysglycemia and hypertension, and to analyze their association with blood pressure indicators.Methods The participants of this study were from the Henan Rural Cohort study. A total of 1,688 patients 18–79 years of age were included in the matched case control study after application of the inclusion and exclusion criteria. Statistical methods were used to analyze the association between glucocorticoids and various indices of blood pressure, through approaches such as logistic regression analysis, trend tests, linear regression, and restricted cubic regression.Results The study population consisted of 552 patients with dysglycemia and hypertension(32.7%).The patients with co-morbidities had higher levels of serum cortisol(P = 0.009) and deoxycortisol(P <0.001). The adjusted odds ratios(and 95% confidence intervals) for dysglycemia with hypertension were1.55(1.18, 2.04) for the highest tertile of Ln-cortisol compared with the lowest tertile. Additionally, the highest Ln-deoxycortisol levels were associated with increased prevalence of dysglycemia with hypertension by 159%(95% confidence interval: 122%, 207%).Conclusions Serum deoxycortisol was positively correlated with systolic blood pressure, pulse pressure, mean arterial pressure, mean blood pressure, and mean proportional arterial pressure.Glucocorticoids(deoxycortisol and cortisol) increase the risk of hypertension in people with dysglycemia, particularly in those with T2 DM.展开更多

As yet, the pre-cise mechanisms by which escin exerts its anti- inflammatory effects remain unclear. The data from current studies indicate that the anti-in-flammatory properties of escin were attributed to its ability to reduce the adhesiveness of neu-trophils and the associated release of inflam-matory mediators;its ability to decrease hista-minic and serotoninergic activities;its ability to inhibit phospholipase A2;its ability to decrease nuclear factor-κ B activation and down-regulate the expression of tumor necrosis factor-α. All these effects are similar to glucocorticoids. Mo- reover, escin depends on adrenal glands to ex-ert its anti-inflammatory effects. Also, our recent research showed that the serum corticosterone level in mice did not increase after a 7-day in-travenous injection of escin. The results sup-port the hypothesis that escin may exert a syn-ergistic anti-inflammatory effect with glucocor-ticoids. Confirming this hypothesis will play a role in elucidating the anti-inflammatory mech- anisms of escin.展开更多

Methods:Children with mycoplasma pneumoniae lobar pneumonia who were treated in the First People's Hospital of Ziyang between January 2015 and January 2018 were chosen as the research subjects and randomly divided into two groups: GCs group were treated with low-dose glucocorticoids + azithromycin, and control group were treated with azithromycin. The inflammatory response indicators and stress response indicators in serum and peripheral blood were measured before treatment as well as 3 d and 5 d after treatment. Results: Compared with those of same group before treatment, peripheral blood TLR4, NF-κB, NOX2, p38MAPK, iNOS, GRP78, PERK, ATF4, CHOP and Caspase-12 expression intensity as well as serum TNF-α, HMGB-1, ICAM-1, NO, MDA and 8-OhdG levels of both groups were significantly decreased after treatment, and peripheral blood TLR4, NF-κB, NOX2, p38MAPK, iNOS, GRP78, PERK, ATF4, CHOP and Caspase-12 expression intensity as well as serum TNF-α, HMGB-1, ICAM-1, NO, MDA and 8-OhdG levels of GCs group after treatment were significantly lower than those of control group. Conclusion: Small-dose glucocorticoid +azithromycin therapy is more effective than azithromycin therapy to suppress the inflammatory and stress response in children with lobar pneumonia.展开更多

They are generally used to quickly dampen inflammation, reduce duration of disease flares and as a maintenance therapy. Conventionally, oral GC are to be prescribed for short periods when possible;mainly, because of their side effects when used for long periods. One of the most important drawbacks of prolonged GC therapy is the risk of bone loss (osteoporosis (OP)) and osteoporotic fragility fracture (OFF). Objective: The aim of this audit was to assess counselling, prevention and management of OP in patients with rheumatic conditions who are or were receiving high doses of oral GC for three months or more against standard international guidelines. Method: The audit was carried out in March/April 2018 for a period of four weeks in a busy rheumatology service in Khartoum, Sudan. A Performa was used to collect data manually from eligible patients and their outpatient medical cards retrospectively. Then, data were audited against standard guidelines. Result: Overall, the selected Centre failed to meet the audit standard of 50% of eligible patients being appropriately managed for OP/OFF according to NICE and ACR guidelines. Conclusion: Huge areas of deficiency in the practice were identified. Acknowledging socioeconomic difficulties in the area of study, simple measures, such as carrying out a fracture risk assessment, optimizing calcium and vitamin D supplements with life style modification and patient education, would have a great impact on patients treated with steroids for rheumatic diseases.展开更多

These consequences(e.g., anti-inflammatory vs. pro-inflammatory) can vary depending on the duration of GC exposure or central nervous system(CNS) injury model. In this review we discuss how GC/GR interactions impact neuronal recovery after a central or peripheral nerve injury and discuss how GC exposure duration can produce divergent CNS neuronal growth responses. Finally we consider how new findings on gender specific immune cell responses after a nerve injury could intersect with GC/GR interactions to impact pain processing.展开更多

The function of GC receptors (GR) was assessed by MMTV reporter assay. Overexpression of GR was done by in vitro transfection and expression of a GR-expressing vector. Immunohistochemical stain of tissues and cells were done by PA1-511A, an anti-GR monoclonal antibody.RESULTS: DEX inhibited cell growth of four (MCF-7, MCF-7/MXR1, MCF-7/TPT300, and HeLa), increased cisplatin cytotoxicity of one (SiHa), and decreased cisplatin cytotoxicity of two (H460 and Hep3B) cell lines. The GR content of the seven cell lines affected by DEX was significantly higher than those of the seven cell lines unaffected by DEX(5.2±2.5×104 sites/cell vs 1.3±1.4×104 sites/cell, P= 0.005).Only two DEX-unresponsive cell lines (NPC-TW01 and NPCTW04) contained high GR amounts in the range (1.9-8.1×104sites/cell) of the seven DEX-responsive cell lines. The GR function of NPC-TW01 and NPC-TW04, however, was found to be impaired. The importance of high cellular amount of GR in mediating DEX susceptibility of the cells was further exemplified by GR dose-dependent drug resistance to cisplatin of AGS, a cell line with low GR content and was unaffected by DEX before transfection of GR-expressing vector. Immunohistochemical studies of human cancer tissues showed that 5 of the 45 (11.1%) breast cancer and 43 of the 85 (50.6%) non-small cell lung cancer had high GR contents at the ranges of the GC-responsive carcinoma cell lines.CONCLUSION: The growth and chemosensitivity of human carcinomas with high GR contents may be affected by GC. However, in light of the heterogeneous and even contradictive effects of GC on these cells, routine examination of GR contents of human carcinoma tissues may not be clinically useful until other markers that help predict the ultimate effect of GC on individual patients are identified.展开更多

文摘Glucocorticoids(GCs) are a group of endocrine-disrupting compounds(EDCs) frequently prescribed against various medical conditions.Recently,GCs have been shown to be effective in managing septic shock in patients infected with the 2019 novel coronavirus(COVID-19).Due to colossal consumption and potential risks to aquatic organisms,GCs have immensely attracted the focus of the scientific research community as a water pollutant.Therefore,the aim of this paper is to review the current knowledge on the occurrence of various GCs in the aquatic environment and their removal during wastewater treatment.A variety of GCs are ubiquitous in surface water,hospital wastewater,and sewage water worldwide.And the minimum concentration in volume is below 0.01 ng/L,and the maximum one is 10 000 ng/L,and enter the environment through hospital and urban wastewater discharging.Compared with natural GCs,higher risks to aquatic environments could be induced by synthetic GCs.The current activated sludge processes used in wastewater treatment plants(WWTPs) are not fully effective in eliminating GCs,some of which may further increase the risk of GC in the environment.In comparison with the aerobic process in WWTPs,the anaerobic and anoxic processes were found to be more efficient for GC degradation.Of the studied GCs,fluticasone propionate,clobetasol propionate,fluocinolone acetonide,and triamcinolone acetonide need more attention due to their low removal efficiencies and strong toxicity.Among the advanced treatment processes,reverse osmosis,ultraviolet irradiation,CaO_(2),and plasma could achieve significant GC activity removal while micro/ultra-filtration,chlorination,and ozonation were less efficient.

文摘AIM: To report the effects of intravenous high-dose glucocorticoids(iv GC) and orbital decompression(OD) surgery for treatment of sight-threatening thyroid-associated ophthalmopathy(TAO).METHODS: A retrospective review of medical records from patients with sight-threatening TAO [definite or highly suspected dysthyroid optic neuropathy(DON)] treated with iv GC(60 cases) and OD(25 cases) was conducted at the Zhongshan Ophthalmic Center between January 2001 and January 2009. Patients were initially treated with iv GC(iv GC group). If no significant improvement in visual function was obtained, they then received OD surgery(OD group). The pre-versus post-treatment efficacies of either iv GC or OD in these patients were assessed using several indices, including visual acuity, intraocular pressure, ocular alignment, ocular motility, and exophthalmos. RESULTS: Nighty-one eyes had definite DON while 79 were considered to have highly suspected DON. In the iv GC group, 51 individuals(85.0%) eventually demonstrated normal vision, while 10 patients(16.7%) demonstrated a reduction in deviation(P<0.01), and 35 cases(58.3%) showed slight improvements in ocular motility(P<0.01). In OD group, visual acuity improved in 24 cases(96.0%, P<0.01) and all patients showed varying reductions of exophthalmos(mean: 4.35±1.13 mm, P<0.01). Eight cases(32.0%) experienced an 8-15 PD reduction of deviation and ocular motility improved in 12 cases(48.0%), while 3 patients(12.0%) developed new-onset strabismus with diplopia post-surgically(P<0.01). Patients were followed up at an average of 1.55±1.07 y. CONCLUSION: Both iv GC and OD show good therapeutic efficacy in the treatment of sight-threatening TAO. Thepresence of extremely poor eyesight(≥0.5 log MAR) was corrected in some patients with iv GC alone, thus sparing these patients from subsequent OD surgery. In patients who were refractory to steroids, subsequent OD surgery often provided satisfactory outcomes, however, new-onset strabismus with diplopia was observed in 12.0% of these cases.

文摘AIM: To evaluate the benefit and harms of high-dose intravenous glucocorticoids(IVGC) as first-line treatment for Graves’ ophthalmopathy(GO).METHODS: A systematic review and Meta-analysis of randomized clinical trials(RCTs) comparing IVGC for the treatment of GO, with placebo or other treatments, were conducted. Electronic databases were searched, and standard methodological guidance of Cochrane Handbook for Systematic Reviews of Interventions was used. The primary outcome was overall response, and secondary outcomes included the improvement and change in clinical activity score(CAS), and adverse events.RESULTS: Ten RCTs were included in the Meta-analysis. Low quality evidence(one trial) showed that participants receiving IVGC achieved significantly higher response compared to participants receiving placebo [risk ratio(RR) 7.50, 95% confidence interval(CI) 1.14 to 49.26]. Moderate quality evidence(four trials) support appreciable benefit of IVGC in response compared with oral glucocorticoids(OGC), with of RR being 1.51(95%CI 1.25 to 1.83). There was low quality evidence(one trial) compatible with appreciable benefit for IVGC plus orbital radiotherapy in response(RR 1.38, 95%CI 1.07 to 1.79), compared with OGC plus orbital radiotherapy. One IVGC versus rituximab trial provided moderate quality evidence suggesting that participants using IVGC achieved significantly lowerresponse compared to participants using rituximab(RR 0.70, 95%CI 0.50 to 0.98). One IVGC versus mycophenolate mofetil(MMF) trial provided moderate quality evidence suggesting that participants using IVGC achieved significantly lower response compared to participants using MMF(RR 0.74, 95%CI 0.63 to 0.88). Very low quality evidence(one trial) showed that participants with dysthyroid optic neuropathy(DON) receiving IVGC were more likely to achieve response compared to participants receiving orbital decompression(RR 3.33, 95%CI 0.51 to 21.89).CONCLUSION: The current evidence is moderate quality, which is sufficient to support IVGC to be as the first-line treatment for moderate-to-severe GO, and the use of rituximab or MMF to be the second-line treatment instead of IVGC. However, the evidence is very low quality, which is insufficient to support the use of IVGC or orbital decompression as the first-line treatment of DON.
文摘Central serous chorioretinopathy(CSC) is characterized by a localized accumulation of subretinal fluid and an idiopathic focal leakage from choroidal vessels. The exact pathogenesis of CSC, however, still remains obscure. In this paper, we hypothesized that CSC may result from a response of choroidal vessels to an acute increase in the environmental light intensity leading to a focal leakage from the choroidal vessels.High levels of glucocorticoids, in our proposed model,may cause persistence rather than initiation of the focal leakage, probably by suppressing the synthesis of collagen and extracellular matrix components and inhibiting fibroblastic activity.
文摘BACKGROUND: Community-acquired pneumonia(CAP) is pneumonia acquired infectiously from normal social contact as opposed to being acquired during hospitalization. CAP is a leading cause of illness and death. This review aims to determine the efficacy and safety of glucocorticoids in the treatment of community-acquired pneumonia(CAP).DATA SOURCES: We searched randomized controlled trials(RCTs) from Pubmed, EMBASE, Cochrane Library, Chinese Journal Full-text Database, and Chinese Biomedical Literature Database to obtain the information by using steroids, glucocorticoids, cortisol, corticosteroids, community-acquired pneumonia and CAP as key words. The quality of RCTs was evaluated. A Meta-analysis was made using Rev Man 5.0 provided by the Cochrance Collaboration.RESULTS: Seven RCTs involving 944 patients were included in the meta-analysis. The mean length of hospital stay in glucocorticoids treatment group was significantly shorter than that in standard treatment group(WMD=–1.70, 95%CI 2.01–1.39, Z=10.81, P<0.00001). No statistically significant differences were found in the mortality rate(RR=0.77,95%CI 0.46–1.27, Z=1.03, P=0.30), the mean length of hospital stay in ICU(WMD=1.17, 95%CI 1.68–4.02, Z=0.81, P=0.42), the incidence of super infection(RR=1.32, 95%CI 0.66–2.63, Z=0.79, P=0.43), the incidence of hyperglycemia(RR=1.84, 95%CI 0.76–4.41, Z=1.36, P=0.17), the incidence of upper gastrointestinal bleeding(RR=1.98, 95%CI 0.37–10.59, Z=0.80, P=0.42) between the standard treatment group and the glucocorticoids treatment group.CONCLUSIONS: The use of glucocorticoids in patients with community-acquired pneumonia can significantly shorten the duration of illness and have a favorable safety profile. However, it could not reduce the overall mortality.
文摘<strong>Background:</strong> Henoch Schonlein Purpura (HSP) is a common immune-related allergic disease in children. It is very important to understand the clinical features of this disease for doctors. <strong>Objective:</strong> To explore the clinical efficacy of glucocorticoids in the treatment of HSP in Tibetan children at high altitude, and to analyze the possible causes of HSP in children at high altitude. The risk factors of the disease provide a reference for the treatment of HSP in children in high altitude areas. <strong>Methods:</strong> Selecting January 2015 to November 2020, 88 children diagnosed with Henoch-Schonlein Purpura in the outpatient and inpatient departments of the People’s Hospital of Bomi County, Tibet Autonomous Region were the subjects of the study. Its gender, age of onset, season of onset, predisposing factors, allergy history, first symptoms, clinical manifestations, laboratory examinations, etc., perform retrospective analysis. <strong>Results: </strong>Among 88 children with allergic purpura, 55 were boys, accounting for 62.5%, and 33 were girls, accounting for 37.5%. Men have more cases than women. All have clinical manifestations of purpura of the skin, among which 35 cases have obvious triggers, of which the above there were 26 cases of respiratory infections, 6 cases of dietary factors, and 3 cases of contact with allergic substances. Simple skin type: 18 cases, accounting for 20.45%;Abdominal type: 6 cases, accounting for 6.82%;2 male cases, accounting for 33.33%;4 female cases, accounting for 66.67%;Articular type: 8 cases, accounting for 33.33%;Renal type: 2 cases, accounting for 2.27%;54 cases of mixed type, accounting for 61.36%. After glucocorticoids, the rashes disappeared, no any adverse reactions. <strong>Conclusion:</strong> Allergic purpura in children is more common in school-age children, and upper respiratory tract infection is the main predisposing factor. Skin purpura is the main clinical manifestation, often associated with lower extremity joint swelling and pain. There is no significant difference in the efficacy and course of the disease between intravenous and oral treatment. Therefore, clinicians should strictly grasp the indications of glucocorticoids to reduce the occurrence of complications.

文摘Objective To our knowledge, no definitive conclusion has been reached regarding the relationship between glucocorticoids and hypertension. Here, we aimed to explore the characteristics of glucocorticoids in participants with dysglycemia and hypertension, and to analyze their association with blood pressure indicators.Methods The participants of this study were from the Henan Rural Cohort study. A total of 1,688 patients 18–79 years of age were included in the matched case control study after application of the inclusion and exclusion criteria. Statistical methods were used to analyze the association between glucocorticoids and various indices of blood pressure, through approaches such as logistic regression analysis, trend tests, linear regression, and restricted cubic regression.Results The study population consisted of 552 patients with dysglycemia and hypertension(32.7%).The patients with co-morbidities had higher levels of serum cortisol(P = 0.009) and deoxycortisol(P <0.001). The adjusted odds ratios(and 95% confidence intervals) for dysglycemia with hypertension were1.55(1.18, 2.04) for the highest tertile of Ln-cortisol compared with the lowest tertile. Additionally, the highest Ln-deoxycortisol levels were associated with increased prevalence of dysglycemia with hypertension by 159%(95% confidence interval: 122%, 207%).Conclusions Serum deoxycortisol was positively correlated with systolic blood pressure, pulse pressure, mean arterial pressure, mean blood pressure, and mean proportional arterial pressure.Glucocorticoids(deoxycortisol and cortisol) increase the risk of hypertension in people with dysglycemia, particularly in those with T2 DM.

文摘BACKGROUND Castleman’s disease(CD),also known as vascular follicular lymphadenopathy is a rare proliferative disease of lymphoid tissue of unknown etiology that is clinically classified as unicentric CD(UCD) or multicentric CD(MCD) depending on lymph node involvement.At present,idiopathic MCD(iMCD) is treated with interleukin-6 inhibitors,but some patients have poor clinical outcomes.This paper reports on a case of iMCD that achieved a good therapeutic effect after treatment with glucocorticoids combined with tofacitinib.The relevant data are summarized and reported below.CASE SUMMARY This paper reports on a case of MCD in a 49-year-old female with persistent peritoneal effusion as the first manifestation and combined with multiple lymphadenopathies.Lymph node biopsy showed Castleman’s disease-like changes.The ascites subsided after treatment with glucocorticoids and tofacitinib,indicating that the treatment was effective.CONCLUSION The combination of glucocorticoids with tofacitinib is an effective regimen for the treatment of CD.
文摘Escin is a natural mixture of triterpenoid as- ponin isolated from the seed of the horse chestnut and demonstrates anti-oedematous and anti-inflammatory effects. As yet, the pre-cise mechanisms by which escin exerts its anti- inflammatory effects remain unclear. The data from current studies indicate that the anti-in-flammatory properties of escin were attributed to its ability to reduce the adhesiveness of neu-trophils and the associated release of inflam-matory mediators;its ability to decrease hista-minic and serotoninergic activities;its ability to inhibit phospholipase A2;its ability to decrease nuclear factor-κ B activation and down-regulate the expression of tumor necrosis factor-α. All these effects are similar to glucocorticoids. Mo- reover, escin depends on adrenal glands to ex-ert its anti-inflammatory effects. Also, our recent research showed that the serum corticosterone level in mice did not increase after a 7-day in-travenous injection of escin. The results sup-port the hypothesis that escin may exert a syn-ergistic anti-inflammatory effect with glucocor-ticoids. Confirming this hypothesis will play a role in elucidating the anti-inflammatory mech- anisms of escin.
文摘Objective: To study the effect of small-dose glucocorticoids + azithromycin therapy on inflammatory response and stress response in children with lobar pneumonia. Methods:Children with mycoplasma pneumoniae lobar pneumonia who were treated in the First People's Hospital of Ziyang between January 2015 and January 2018 were chosen as the research subjects and randomly divided into two groups: GCs group were treated with low-dose glucocorticoids + azithromycin, and control group were treated with azithromycin. The inflammatory response indicators and stress response indicators in serum and peripheral blood were measured before treatment as well as 3 d and 5 d after treatment. Results: Compared with those of same group before treatment, peripheral blood TLR4, NF-κB, NOX2, p38MAPK, iNOS, GRP78, PERK, ATF4, CHOP and Caspase-12 expression intensity as well as serum TNF-α, HMGB-1, ICAM-1, NO, MDA and 8-OhdG levels of both groups were significantly decreased after treatment, and peripheral blood TLR4, NF-κB, NOX2, p38MAPK, iNOS, GRP78, PERK, ATF4, CHOP and Caspase-12 expression intensity as well as serum TNF-α, HMGB-1, ICAM-1, NO, MDA and 8-OhdG levels of GCs group after treatment were significantly lower than those of control group. Conclusion: Small-dose glucocorticoid +azithromycin therapy is more effective than azithromycin therapy to suppress the inflammatory and stress response in children with lobar pneumonia.
文摘Background: Glucocorticoids (GC) are considered a mainstay as well as symptomatic and disease-modifying therapy for rheumatic diseases. They are generally used to quickly dampen inflammation, reduce duration of disease flares and as a maintenance therapy. Conventionally, oral GC are to be prescribed for short periods when possible;mainly, because of their side effects when used for long periods. One of the most important drawbacks of prolonged GC therapy is the risk of bone loss (osteoporosis (OP)) and osteoporotic fragility fracture (OFF). Objective: The aim of this audit was to assess counselling, prevention and management of OP in patients with rheumatic conditions who are or were receiving high doses of oral GC for three months or more against standard international guidelines. Method: The audit was carried out in March/April 2018 for a period of four weeks in a busy rheumatology service in Khartoum, Sudan. A Performa was used to collect data manually from eligible patients and their outpatient medical cards retrospectively. Then, data were audited against standard guidelines. Result: Overall, the selected Centre failed to meet the audit standard of 50% of eligible patients being appropriately managed for OP/OFF according to NICE and ACR guidelines. Conclusion: Huge areas of deficiency in the practice were identified. Acknowledging socioeconomic difficulties in the area of study, simple measures, such as carrying out a fracture risk assessment, optimizing calcium and vitamin D supplements with life style modification and patient education, would have a great impact on patients treated with steroids for rheumatic diseases.

文摘Glucocorticoids(GCs)have been widely used as immunosuppressants and antiinflammatory agents to treat a variety of autoimmune and inflammatory diseases,and they fully exert their anti-inflammatory and immune-regulating effects in the body.The effect of GCs on white blood cells is an important part of their action.GCs can cause changes in peripheral blood white blood cell counts by regulating the proliferation,differentiation,and apoptosis of white blood cells.Although the total number of white blood cells,neutrophil counts,lymphocytes,and eosinophils increases,the counts of basic granulocytes and macrophages decreases.In addition,GCs can regulate the activation and secretion of white blood cells,inhibit the secretion of a variety of pro-inflammatory cytokines,the expression of chemokines,and promote the production of anti-inflammatory cytokines.For patients on GC therapy,the effects of GCs on leukocytes were similar to the changes in peripheral blood caused by bacterial infections.Thus,we suggest that clinicians should be more cautious in assessing the presence of infection in children with long-term use of GCs and avoid overuse of antibiotics in the presence of elevated leukocytes.GCs work through genomic and non-genomic mechanisms in the human body,which are mediated by GC receptors.In recent years,studies have not fully clarified the mechanism of GCs,and further research on these mechanisms will help to develop new therapeutic strategies.

文摘To assess all available data to compare the efficacy of glucocorticoids treatment and orbital decompression for dysthyroid optic neuropathy(DON).PubMed,EMBASE,the Cochrane Library databases as well as other sources were searched by two independent reviewers followed by extensive hand-searching for the identification of relevant studies.The primary outcomes were the improvement in visual acuity and responder rate.Secondary outcomes were the proptosis reduction,change in diplopia,and clinical activity score(CAS).One randomized controlled trial,three retrospective case series and one prospective case series met the inclusion criteria.They were divided into intravenous high-dose glucocorticoids(ivGC)group and orbital decompression(OD)group.Both groups demonstrated improvement in visual acuity.In addition,the proportion of patients with improved vision in OD group was higher than that in ivGC group(P<0.001).Post-treatment proptosis reduction was also reported in both groups.Overall,weighted mean in proptosis reduction estimated at 1.64 and 5.45 mm in patients treated with ivGC and OD respectively.This study also presented results regarding pre-existing and new-onset diplopia.Apart from diplopia,a wide variety of minor and major complications were noted in 5 included studies.The most common complication in ivGC group and OD group was Cushing's syndrome and epistaxis respectively.The present systematic review shows that both glucocorticoids treatment and OD are effective in treating DON and OD may work better in improving visual acuity and reducing proptosis.However,high-quality,large-sample,controlled studies need to be performed in the future.
文摘Glucocorticoid and glucocorticoid receptor(GC/GR) interactions alter numerous aspects of neuronal function. These consequences(e.g., anti-inflammatory vs. pro-inflammatory) can vary depending on the duration of GC exposure or central nervous system(CNS) injury model. In this review we discuss how GC/GR interactions impact neuronal recovery after a central or peripheral nerve injury and discuss how GC exposure duration can produce divergent CNS neuronal growth responses. Finally we consider how new findings on gender specific immune cell responses after a nerve injury could intersect with GC/GR interactions to impact pain processing.

文摘AIM: To determine how glucocorticoids (GCs) may affect the growth and chemosensitivity of common carcinoma cells.METHODS: The effect of dexamethasone (DEX) on growth and chemosensitivity was assessed in 14 carcinoma cell lines. The function of GC receptors (GR) was assessed by MMTV reporter assay. Overexpression of GR was done by in vitro transfection and expression of a GR-expressing vector. Immunohistochemical stain of tissues and cells were done by PA1-511A, an anti-GR monoclonal antibody.RESULTS: DEX inhibited cell growth of four (MCF-7, MCF-7/MXR1, MCF-7/TPT300, and HeLa), increased cisplatin cytotoxicity of one (SiHa), and decreased cisplatin cytotoxicity of two (H460 and Hep3B) cell lines. The GR content of the seven cell lines affected by DEX was significantly higher than those of the seven cell lines unaffected by DEX(5.2±2.5×104 sites/cell vs 1.3±1.4×104 sites/cell, P= 0.005).Only two DEX-unresponsive cell lines (NPC-TW01 and NPCTW04) contained high GR amounts in the range (1.9-8.1×104sites/cell) of the seven DEX-responsive cell lines. The GR function of NPC-TW01 and NPC-TW04, however, was found to be impaired. The importance of high cellular amount of GR in mediating DEX susceptibility of the cells was further exemplified by GR dose-dependent drug resistance to cisplatin of AGS, a cell line with low GR content and was unaffected by DEX before transfection of GR-expressing vector. Immunohistochemical studies of human cancer tissues showed that 5 of the 45 (11.1%) breast cancer and 43 of the 85 (50.6%) non-small cell lung cancer had high GR contents at the ranges of the GC-responsive carcinoma cell lines.CONCLUSION: The growth and chemosensitivity of human carcinomas with high GR contents may be affected by GC. However, in light of the heterogeneous and even contradictive effects of GC on these cells, routine examination of GR contents of human carcinoma tissues may not be clinically useful until other markers that help predict the ultimate effect of GC on individual patients are identified.
