title: Fever, thrombocytopenia, and AKI-A profile of malaria, dengue, and leptospirosis with renal failure in a South Indian tertiary-care hospital.
abstract: BACKGROUND
  In the tropics, the triad of fever, thrombocytopenia, and AKI portends a grim prognosis with high mortality and a severe strain on already-stretched resources. Malaria, dengue, and leptospirosis account for most cases. We undertook a review of cases to determine factors accounting for adverse prognosis.
  
  
  METHODS
  All patients presenting to the emergency room (ER) with a history of fever, thrombocytopenia, and renal failure were included in the study. Patients were followed until discharge or death, and end points looked at were 1-week and 30-day mortality, and renal function upon discharge. Parameters like liver function test (LFT), renal function, and platelet count upon discharge were also documented.
  
  
  RESULTS
  A total of 43 patients was included in the study. Mean age was 42.5 years with 86% males. Mean APACHE and SOFA scores on admission were 23.89 and 15.42, respectively. Mean admission platelet counts were 41,000. Mean serum creatinine was 4.1, and bilirubin was 9.94. A platelet count of < 34,000, serum creatinine of > 4, albumin of > 2.3, SOFA score of > 20, and APACHE score of > 32.2 were significantly predictive of 1 week mortality. Need for mechanical ventilation, oliguria on admission, and need for dialysis all were highly predictive of 30-day mortality. In addition, a serum bicarbonate of < 12, INR of > 1.5, hemoglobin of < 9.5 were highly predictive of higher 30 day mortality. Overall, 1-week mortality was 16.3%, of which 48% was accounted for by patients with leptospirosis.
  
  
  CONCLUSIONS
  Factors like low platelet count, oliguria, need for dialysis, high APACHE and SOFA scores on admission, need for mechanical ventilation, and low serum albumin portend a grave prognosis. There is need for randomized control trials (RCT) to further determine adverse prognostic factors in this subsect of patients.
