HIV-associated nephropathy (HIVAN) is a kidney disease common among HIV positive patients, especially patients of African origin. The condition rapidly deteriorates if left untreated. Various treatment options exist, but the benefit of each is unknown. These include: antiretroviral therapy, steroids, angiotensin-converting enzyme inhibitors (ACEi) and cyclosporin. The aim of this review was to determine the benefits and harms of each treatment option. No completed randomised control trials (RCT) of any interventions for HIVAN were found and so the effects of the treatment options could not be evaluated. However, the results of observational studies identified showed that steroids and ACEI were beneficial in improving the kidney functions of patients. We await the results of three ongoing studies, however more RCTs are needed.
阅读完整摘要
Human immunodeficiency virus-associated nephropathy (HIVAN) is the most common cause of end stage kidney disease (ESKD) in human immunodeficiency virus-1 (HIV-1) serotype patients and it mostly affects patients of African descent. It rapidly progresses to ESKD if untreated. The goal of treatment is directed toward reducing HIV-1 replication and/or slowing the progression of chronic kidney disease. The following pharmacological agents have been used for the treatment of HIVAN: antiretroviral therapy, angiotensin-converting enzyme inhibitors (ACEi), steroids and recently cyclosporin. Despite this, the effect of each intervention is yet to be evaluated.
研究目的
To evaluate the benefits and harms of adjunctive therapies in the management of HIVAN and its effects on symptom severity and all-cause mortality.
检索策略
In January 2012 we searched the Cochrane Renal Group's Specialised Register, AIDS Education Global Information System (AEGIS database), ClinicalTrial.gov, the WHO International Clinical Trials Registry Portal, and reference lists of retrieved articles without language restrictions. In our original review we searched CENTRAL, MEDLINE, EMBASE, and AIDSearch, in addition to contacting individual researchers, research organisations and pharmaceutical companies.
纳入排除标准
Randomised controlled trials (RCTs) and quasi-RCTs of any therapy used in the treatment of HIVAN.
资料收集与分析
We independently screened the search outputs for relevant studies and to retrieve full articles when necessary. For dichotomous outcomes results were to be expressed as risk ratios with 95% confidence intervals, and for continuous scales of measurement the mean difference was to be used.
主要结果
We identified four relevant ongoing studies: one is still ongoing; two have completed recruitment but are yet to be published; and the fourth study was suspended for unspecified reasons. No completed RCTs or quasi-RCTs were identified. We summarised and tabulated the data from the observational studies, however no formal analyses were performed.
作者结论
There is currently no RCT-based evidence upon which to base guidelines for the treatment of HIVAN, however three ongoing studies have been identified. Data from observational studies suggest steroids and angiotensin-converting enzyme inhibitors appear to improve kidney function in patients with HIVAN, however no formal analyses were performed in this review. This review highlights the need for good quality RCTs to address the effects of interventions for treating this group.
