Recognition of pernicious syndromes in malaria infections.
The case records of 64 patients with malaria over a five year period admitted to the University Hospital, Kuala Lumpur were examined. There were 32 cases of P. falciparum, 26 cases of P. vivax and two cases of mixed infections. Four cases of P. malariae were recorded. The clinical findings, biochemical and haematological parameters were examined for any indication of a pernicious syndrome. A high index of suspicion of a malarial infection may be based on the findings of anaemia, thrombocytopaenia, hyponatraemia, renal failure and abnormal liver function tests in the face of a negative blood film. These pernicious syndromes occur more often in malignant tertian malaria (anaemia 50%, hyponatraemia 39.1%) but a high percentage of the other malarial species show these abnormalities (P. vivax anaemia 57.7%, hyponatraemia 19.2%). When these abnormalities are present but blood films for malaria parasites are negative, repeat blood films are warranted until a parasitological diagnosis is achieved and correct treatment may be started.
