Abstract

Blood coagulation and platelet aggregation were assessed in children, with nephrotic syndrome who were divided into the following groups: (1) relapse without treatment; (2) relapse on steroids; (3) early remission; (4) late remission and (5) steroid resistant. The renal histological findings were also recorded. Plasma antithrombin III (ATIII) levels were markedly reduced in groups 1 and 2, below normal in group 3 and were normal in groups 4 and 5. There was significant urinary loss of AT III in groups 1 and 2 as well as in group 5. Plasma fibrinogen fluctuations exhibited the expected negative correlations with plasma AT III. Reptilase time showed significant prolongation in groups 1, 2 and 3, and was near normal in groups 4 and 5. Platelet aggregation in response to arachidonic acid exhibited aggregation followed by disaggregation in groups 1, 2, 4 and 5, and was normal in group 3. Hyperaggregation in response to decreasing doses of ADP was noted in all patient groups as well as controls with no relationship to serum albumin levels. Aggregation responses to collagen and ristocetin were normal. It is concluded that: 1. The fluctuations in AT III levels in childhood nephrotic syndrome are determined by the response to steroids and not by the renal histology per se. 2. An acquired fibrin polymerization defect (dysfibrinogenaemia) and an abnormality of the prostaglandin pathway of platelet activation, both reversible, are yet other haemostatic abnormalities in childhood nephrosis. 3. The discrepancies in the literature on haemostatic parameters, specially AT III in childhood nephrosis, would not have arisen if their fluctuation in relation to steroid therapy as well as the renal histological features of nephrotic syndrome had been documented simultaneously.
