Renal involvement in human trichinosis.

A renal clinicopathologic study was made in five patients with trichinosis. The patients had mild proteinuria and abnormal urinary sediment that disappeared after the disease was under control. Creatinine clearance was normal in all cases. p-Aminohippurate clearance was decreased in two patients who had hypoalbuminemia. A renal biopsy specimen showed mesangial proliferative glomerulonephritis with deposition of immunoglobulins and C3 in the mesangial areas and along the capillary loops. Glomerular fibrin deposition was noted in one case. Deposition of hyaline material and C3 was observed in the arteriolar wall. Tubular interstitial changes were not present.

Heat oedema: a clinical study.

Transient generalized oedema was observed in a patient upon exposure to a hot climate. Oedema disappeared in 5 days. Clinical study during oedema revealed decreased urine volume, high urine osmolality, high urine sodium concentration, increased blood volume, hyponatraemia and hypo-osmolality. The total solute excretion was unchanged. The endogenous creatinine and para-aminohippurate clearances were normal. The findings were suggestive of increased antidiuretic hormone activity, and heat might be responsible.

Furosemide and acute renal failure.

High dose of intravenous furosemide (2 g/24 hr) was given to six patients with acute renal failure due to leptospirosis. The results, based on urine flow, changes in serum creatinine and creatinine clearance, were compared with a control group of eight patients with the same disease and comparable degree of renal failure. Excellent diuresis was observed following furosemide therapy but renal function and the clinical course of the disease were unaltered. The duration of renal failure was the same in both groups.

Renal failure in malaria: a pathophysiologic study.

A pathophysiologic study was made in 15 patients with acute renal failure due to falciparum malaria. Marked increase in plasma fibrinogen and elevation of serum fibrin degradation products were observed in all cases. The other coagulation parameters including prothrombin time, partial thromboplastin time, factor V and factor VIII were within the normal limits. Plasma hemoglobin was minimal. The blood viscosity was significantly increased. Blood volume study in 5 patients showed initial hypovolemia followed by hypervolemia and normovolemia. Decreased cortical renal blood flow was noted in renal hemodynamic study using 133Xe. Plasma renin activity was increased. Intravenous pyelography during the oliguric phase of renal failure revealed a poor nephrogram which increased in density at 24 and 48 h after the injection of the contrast material. The findings suggest the significance of reduction of renal blood flow in the pathogenesis of renal failure in human malaria. The roles of blood hyperviscosity and hypovolemia are emphasized.

The kidney in tropical snakebite.

Renal pathological changes were studied by renal biopsy in 31 patients bitten by tropical poisonous snakes which included seasnake (2 cases), cobra (11 cases), green-pit viper (8 cases) and Russell's viper (10 cases). Renal failure was present only in patients bitten by seasnake and Russell's viper. Glomerular mesangial proliferation was noted in the victims of cobra, green-pit viper and Russell's viper. There was deposition of IgM AND C3 in the glomerular mesangium with extension along the capillary walls. Fibrin deposition was seen in green-pit viper cases. By electron microscopy electron dense deposits were observed in the glomerular basement membrane-like matrix. Irregular thickening of the basement membrane was found in cobra cases. Vascular changes included arteritis of the interlobular artery with C3 deposition in the arterial walls in Russell's viper cases and thrombophlebitis in both green-pit viper's and Russell's viper's victims. Dense deposits of C3 in the arteriolar walls were noted in viper-bite and cobra-bite. Tubular necrosis was demonstrated in patients envenomated by green-pit viper and Russell's viper. Necrosis was severe in seasnake and Russell's viper poisoning, but was mild in green-pit viper cases.
