About emergency care

Severe malaria is a life-threatening complication of malaria infection, most commonly caused by the parasite Plasmodium falciparum, though P. vivax and P. knowlesi can also lead to severe disease. It occurs when the infection progresses to involve serious organ failure or abnormalities in the patient's blood or metabolism. If left untreated, it can rapidly lead to death. Key Features and Symptoms: Severe malaria presents with a range of symptoms, often escalating from those of uncomplicated malaria (fever, chills, headache, body aches, nausea, vomiting, diarrhea). The defining features of severe malaria, according to the WHO, often include one or more of the following: * Impaired consciousness/coma (Cerebral Malaria): This is a severe neurological complication where infected red blood cells block blood vessels in the brain, potentially leading to permanent brain damage, seizures, or coma. * Prostration: Generalized weakness making the patient unable to sit, stand, or walk without assistance. * Multiple convulsions: More than two episodes within 24 hours. * Breathing difficulties/respiratory distress: Can include deep, acidotic breathing or acute respiratory distress syndrome (ARDS) due to fluid buildup in the lungs. * Severe anemia: Destruction of red blood cells leading to a dangerously low hemoglobin level (e.g., <5 g/dL in children, <7 g/dL in adults). * Circulatory collapse/shock: Very low blood pressure. * Acute kidney injury/failure: Impaired kidney function. * Jaundice: Yellowing of the skin and eyes, usually accompanied by other signs of organ dysfunction. * Abnormal bleeding or disseminated intravascular coagulation (DIC). * Hypoglycemia: Dangerously low blood sugar, especially in children and pregnant women. * Metabolic acidosis: Excessive acid in the blood and tissue fluids. * High parasite density (hyperparasitemia): A high percentage of red blood cells infected with malaria parasites (e.g., \geq 5%). Diagnosis: Diagnosis of severe malaria typically involves: * Clinical suspicion: A high index of suspicion is crucial, especially in individuals who have traveled to malaria-endemic areas or reside there and present with severe symptoms. * Blood tests: * Microscopy (blood film examination): This is the gold standard for confirming malaria, identifying the parasite species, and quantifying parasite density. * Rapid Diagnostic Tests (RDTs): These can provide quick results, especially in settings where microscopy is unavailable. * Assessment of organ function: Blood tests to check kidney function, liver function, blood sugar, and complete blood count are essential to assess the severity of the disease and identify complications. Treatment: Severe malaria is a medical emergency requiring immediate and aggressive treatment. Every minute counts as symptoms can deteriorate rapidly. * Parenteral Antimalarials: * Intravenous (IV) artesunate: This is the primary treatment recommended by the WHO for severe malaria in all patients, including infants, pregnant women, and lactating women. Treatment with IV artesunate should be initiated as soon as possible and continued for at least 24 hours until the patient can tolerate oral medication. * If IV artesunate is not immediately available, other parenteral antimalarials like quinine may be used as an alternative, or oral antimalarials can be given until artesunate becomes available. * Supportive Care: Patients with severe malaria require admission to a hospital and close monitoring. Supportive care is crucial and may include: * Fluid management. * Correction of electrolyte imbalances. * Management of convulsions. * Blood transfusions for severe anemia. * Management of respiratory distress. * Monitoring and treatment of hypoglycemia. * Addressing any other organ dysfunction. * Transition to Oral Therapy: Once the patient has received at least 24 hours of parenteral therapy and can tolerate oral medications, treatment should be completed with a full three-day course of an artemisinin-based combination therapy (ACT). Complications: Severe malaria can lead to various serious complications, including: * Cerebral malaria (with potential for permanent neurological damage) * Severe anemia * Acute kidney injury/failure * Acute respiratory distress syndrome (ARDS) * Hypoglycemia * Metabolic acidosis * Liver failure and jaundice * Circulatory collapse/shock * Abnormal bleeding * Splenic rupture (less common) In pregnant women, severe malaria also increases the risk of premature birth, low birth weight, stillbirth, miscarriage, and maternal mortality.
