Patients with biopsy-proven HIVAN treated with ART had better renal survival compared with patients who did not receive ART. HIVAN should be considered as an indication to initiate ART.
To determine the value of human immunodeficiency virus type 1 (HIV-1) RNA level in distinguishing HIV-associated nephropathy from non-HIV-associated nephropathy renal pathological conditions, we retrospectively compared renal histopathological findings for 86 HIV-infected patients according to HIV-1 RNA levels. We found that HIV-associated nephropathy was unlikely among patients with HIV-1 RNA levels <400 copies/mL. Hypertensive vascular disease surpassed HIV-associated nephropathy as the most common renal pathological finding among the entire cohort. HIV-1 RNA level did not correlate with renal survival.
This study provides evidence that, among patients with human immunodeficiency virus and kidney disease, the highest and lowest levels of sonographic echogenicity have diagnostic value in respectively establishing or excluding human immunodeficiency virus-associated nephropathy.
A recent meta-analysis suggested that the use of rosiglitazone increases the risk of myocardial infarction (MI) in patients with type 2 diabetes mellitus. It is unclear whether this is a class effect of thiazolidinediones (TZD). We did a meta-analysis to evaluate cardiovascular outcomes with the use of pioglitazone. Randomized, controlled trials in which pioglitazone was compared with placebo or other hypoglycemic agents were considered for analysis. Studies were included if the data for MI were available. Studies were identified with use of relevant search words in Medline, Pubmed, EMBASE, CINAHL, and Cochrane databases. Data abstraction was done by 2 individual authors using a standardized protocol. The relative risk across all study groups was computed by the Mantel-Haenszel method, and interstudy heterogeneity was assessed by the chi method. All results were computed according to 95% confidence intervals. Five trials (N = 9965) met the inclusion criteria for analysis. The relative risk for MI was 0.86 (0.69-1.07; P = 0.17). The relative risks for stroke and revascularization were 0.79 (0.61-1.02; P = 0.07) and 0.40 (0.13-1.23; P = 0.11), respectively. Pioglitazone does not increase the risk for MI and may decrease the risk for stroke and revascularization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
