A Systematic Review of Prophylactic Anticoagulation in Nephrotic Syndrome.

ABSTRACT: Introduction:Nephrotic syndrome is associated with an increased risk of venous and arterial thromboembolism, which can be as high as 40% depending on the severity and underlying cause of nephrotic syndrome. The 2012 Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommend prophylactic anticoagulation only in idiopathic membranous nephropathy but acknowledge that existing data are limited and of low quality. There is a need for better identification of vulnerable patients in order to balance the risks of anticoagulation. Methods:We undertook a systematic search of the topic in MEDLINE, EMBASE and COCHRANE databases, for relevant articles between 1990 and 2019. Results:A total of 2381 articles were screened, with 51 full-text articles reviewed. In all, 28 articles were included in the final review. Conclusion:We discuss the key questions of whom to anticoagulate, when to anticoagulate, and how to prophylactically anticoagulate adults with nephrotic syndrome. Using available evidence, we expand upon current KDIGO guidelines and construct a clinical algorithm to aid decision making for prophylactic anticoagulation in nephrotic syndrome.

Project description:BackgroundRandomised controlled trials (RCTs) have reported inconsistent effects from intensified anticoagulation on clinical outcomes in Covid-19. We performed an aggregate data meta-analysis from available trials to quantify effect on non-fatal and fatal outcomes and identify subgroups who may benefit.MethodsWe searched multiple databases for RCTs comparing intensified (intermediate or therapeutic dose) versus standard prophylactic dose anticoagulation in adults with laboratory-confirmed Covid-19 through 19 January 2022. The primary efficacy outcome was all-cause mortality at end of follow-up or discharge. We used random effects meta-analysis to estimate pooled risk ratios for mortality, thrombotic, and bleeding events, and performed subgroup analysis for clinical setting and dose of intensified anticoagulation.ResultsEleven RCTs were included (n = 5873). Intensified anticoagulation was not associated with a reduction in mortality for up to 45 days compared with prophylactic anticoagulation: 17.5% (501/2861) died in the intensified anticoagulation group and 18.8% (513/2734) died in the prophylactic anticoagulation group, relative risk (RR) 0.93; 95%CI, 0.79 - 1.10. On subgroup analysis, there was a possible signal of mortality reduction for inpatients admitted to general wards, although with low precision and high heterogeneity (5 studies; RR 0.84; 95% CI, 0.49 - 1.44; I 2 = 75%) and not significantly different to studies performed in the ICU (interaction P = 0.51). Risk of venous thromboembolism was reduced with intensified anticoagulation compared with prophylaxis (8 studies; RR 0.53, 95%CI 0.41 - 0.69; I 2 = 0%). This effect was driven by therapeutic rather than intermediate dosing on subgroup analysis (interaction P =0.04). Major bleeding was increased with use of intensified anticoagulation (RR 1.73, 95% CI 1.17 - 2.56) with no interaction for dosing and clinical setting.ConclusionIntensified anticoagulation has no effect on short term mortality among hospitalised adults with Covid-19 and is associated with increased risk of bleeding. The observed reduction in venous thromboembolism risk and trend towards reduced mortality in non-ICU hospitalised patients requires exploration in additional RCTs.SummaryIn this aggregate data meta-analysis, use of intensified anticoagulation had no effect on short term mortality among hospitalised adults with Covid-19 and was associated with increased risk of bleeding.

Project description:Primary nephrotic syndrome (PNS) is a common renal disease that presents with heavy proteinuria and hypoalbuminemia. Despite notable advances in its treatment, some patients show poor responses and clinical outcomes when treated with conventional Western medicine (WM). Chinese herbal injections (CHIs) have been reported to have beneficial effects for PNS. The aim of the present study was to comprehensively determine the efficacy and safety of CHIs for PNS in adults using a network meta-analysis approach. PubMed, Embase, the Cochrane library, and four Chinese databases were systematically searched to identify randomized controlled trials (RCTs) using CHIs for treatment of PNS published before June 1, 2019. Quality assessment of the identified RCTs was performed according to the Cochrane Handbook. Pooled odds ratios (OR) or mean differences (MD) with corresponding 95% confidence intervals (CI) were calculated for discrete or continuous variables, respectively. The primary outcome was complete/total remission and secondary outcomes were serum albumin and urinary protein excretion. The surface under the cumulative ranking curve (SUCRA) value and cluster analyses were used to rank treatment by probability. Eighty-five studies involving 11 CHIs and 5801 subjects were included. Compared with WM alone, CHI plus WM showed an improved complete/total remission rate as well as higher serum albumin and lower 24-hour urinary protein excretion, except in the following: Yinxingye injection plus WM did not improve the total remission rate, and Dengzhanhua or Xueshuantong injection plus WM did not lower the 24-hour urinary protein excretion. Either Danhong (DH) or Dengzhanhua (DZH) injection plus WM was the preferable treatment for PNS based on SUCRA and cluster analyses of clinical remission and adverse events. However, considering that literature in this area is limited, these results need further validation. CHIs administered as adjuvants to WM showed favourable outcomes for PNS. DH + WM and DZH + WM might be the potential optimal therapies for PNS.
