dc.description.abstractBackground: Renal involvement in Schistosoma mansoni infection is not well studied. The aim of this study is to investigate the occurrence of renal abnormalities in patients with hepatosplenic schistosomiasis (HSS), especially renal tubular disorders. Methods: This is a cross-sectional study with 20 consecutive patients with HSS followed in a medical center in Maceio´ , Alagoas, Brazil. Urinary acidification and concentration tests were performed using calcium chloride (CaCl2) after a 12-h period of water and food deprivation. The biomarker monocyte chemoattractant protein 1 (MCP-1) was quantified in urine. Fractional excretion of sodium (FENa+), transtubular potassium gradient (TTKG) and solute-free water reabsorption (TcH2O) were calculated. The HSS group was compared to a group of 17 healthy volunteers. Results: Patients’ mean age and gender were similar to controls. Urinary acidification deficit was found in 45% of HSS patients. Urinary osmolality was significantly lower in HSS patients (588¡112 vs. 764¡165 mOsm/kg, p50,001) after a 12-h period of water deprivation. TcH2O was lower in HSS patients (0.72¡0.5 vs. 1.1¡0.3, p50.04). Urinary concentration deficit was found in 85% of HSS patients. The values of MCP-1 were higher in HSS group than in control group (122¡134 vs. 40¡28 pg/mg-Cr, p50.01) and positively correlated with the values of microalbuminuria and proteinuria. Conclusions: HSS is associated with important kidney dysfunction. The main abnormalities found were urinary concentrating ability and incomplete distal acidification defect, demonstrating the occurrence of tubular dysfunction. There was also an increase in urinary MCP-1, which appears to be a more sensitive marker of renal damage than urinary albumin excretion rate.pt_BR
