18 patients with biopsy proven chronic proliferative glomerulonephritis have been studied, 10 of the 18 received daily subcutaneous injections of depo-heparin until death or for a period of at least 1 year. 8 of the 10 patients so treated demonstrated significant improvement in renal function as measured by serial determination of endogenous creatinine clearance, Addis count, protein permeability index, and renal biopsy. 1 patient with severely impaired function prior to heparin therapy did not improve, but renal function remained stable during the period of treatment. 8 of the 10 control patients were followed adequately for evaluation. Of these 8, 6 demonstrated progressive diminution of renal function, 4 expired in renal failure; in addition, 1 control patient followed too sporadically to include in the study is known to have died of renal failure.
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.
