Malarial nephropathy in a tertiary care setup--an observational study.

Malaria is endemic in Nepal. Its poor outcome is associated with acute renal failure (ARF), hepatopathy and cerebral malaria. The clinical profiles, biochemical parameters and outcome of 25 patients of falciparum malaria diagnosed either by optimal test, peripheral blood smear (PBS) or Quantitative buffy coat (QBC) admitted in BP Koirala Institute of Health Sciences were studied. Majority of patients (84%) was from the age group 15-45 years. Mean age was 33 +/- 16 years. There were 16 males and 9 females. All had history of fever. Twenty patients were optimal positive, 9 positive in PBS and 12 were QBC positive for Plasmodium falciparum. Mean duration of fever was 13 +/- 9 days. Patients with renal or hepatic involvement presented earlier. Renal dysfunction (S. creatinine > 1.5 mg/dl) was present in 60%. Ten patients had ARF (S. creatinine > 3 mg/dl); five out of them were oliguric/anuric. S. creatinine in patients without renal dysfunction, with renal dysfunction but without renal replacement therapy (RRT) and who underwent RRT were 1.1 +/- 0.24, 3.98 +/- 1.9 and 4.53 +/- 1.72 mg/dL respectively. Serum creatinine of patients with and without hepatic dysfunction respectively were 3.26 +/- 1.98 and 1.26 +/- 0.48 mg/dL (p = 0.001 (CI 0.9-3.10)). Total bilirubin of > 2.5 mg/dl was present in 77%. Total bilirubin of patients with renal dysfunction who underwent and who did not undergo RRT were 10.3 vs. 3.76 mg/dL (p = 0.024 (CI 1.07-12.0)). Fourteen patients had cerebral malaria. Eight patients underwent RRT (hemodialysis or peritoneal dialysis). Six patients died. Five died within 48 hrs of presentation. Patients who had renal and/or hepatic dysfunction had increased morbidity and mortality.
