In this article, we will discuss the WHO Criteria for Severe Cerebral Malaria (falciparum malaria). So, let’s get started.

WHO Criteria for Severe Cerebral Malaria (falciparum malaria)

  • Cerebral malaria (unexplained unarousable coma)
  • Severe anemia (Hb <5 g/dl or hematocrit <15%)
  • Renal failure (oliguria-urine output <400 ml/day or <12 ml/kg/day plus serum creatinine >3 mg/dl or 265 μmol/L)
  • Non-cardiogenic pulmonary edema (ARDS*, hypoxemia, respiratory failure)
  • Hypoglycemia (whole blood glucose <40 mg/dl or 2.2 mmol/L)
  • Circulatory collapse (systolic BP <70 mmHg with cold clammy extremities)
  • Spontaneous bleeding, DIC** (prolonged PT***, PTT***), and thrombocytopenia
  • Repeated generalized convulsions (>3 in 24 hours)
  • Acidemia (arterial pH <7.25) or acidosis (plasma bicarbonate <15 mmol/L)
  • Hemoglobinuria (not drug-induced)
  • Jaundice (icterus or serum bilirubin >3 mg/dl)
  • Hyperparasitemia (>5% in non-immune patients or >10,000/ml)

Some important medical abbreviations

  • *ARDS: Acute respiratory distress syndrome
  • **DIC: Disseminated Intravascular Coagulation
  • ***PT: Prothrombin time
  • ****PTT: Partial thromboplastin time
