Pernicious syndromes in Plasmodium infections

Area of Science:

• Tropical Medicine
• Infectious Diseases
• Parasitology

Background:

• Malaria remains a significant global health challenge, particularly in tropical regions.
• Plasmodium vivax and Plasmodium falciparum are the most prevalent malaria species affecting humans.
• Pernicious syndromes represent severe, life-threatening complications of malaria.

Purpose of the Study:

• To determine the prevalence of pernicious syndromes in male patients with malaria in northeastern India.
• To analyze the association between malaria species (P. vivax, P. falciparum, mixed) and the occurrence of pernicious syndromes.
• To identify common complications associated with malaria infections.

Main Methods:

• Retrospective analysis of medical records of 560 male patients admitted between June 1978 and June 1980.
• Categorization of patients based on malaria parasite species: P. vivax, P. falciparum, or mixed infection.
• Documentation and classification of observed pernicious syndromes and organ involvement.

Main Results:

• Of 560 patients, 31.8% had P. vivax, 55.1% had P. falciparum, and 13.1% had mixed infections.
• Pernicious syndromes were observed in 68 patients (12.1%), with cerebral and hematopoietic complications being most frequent (29.4% and 47.1%).
• Complication rates were lowest in P. vivax malaria (2.3%), higher in P. falciparum malaria (14.2%), and highest in mixed infections (27.4%).

Conclusions:

• Plasmodium falciparum and mixed malaria infections are associated with a higher risk of developing pernicious syndromes compared to P. vivax malaria.
• Cerebral and hematopoietic complications are significant concerns in severe malaria cases.
• Timely diagnosis and appropriate therapy are essential for improving patient outcomes in malaria.
