Insights
Plasmodium vivax malaria can cause severe complications in children, including anemia, thrombocytopenia, and organ dysfunction. Recognizing severe vivax malaria is crucial for timely intervention and improved outcomes.
Area of Science:
- Pediatric infectious diseases
- Malariology
- Clinical tropical medicine
Background:
- Plasmodium vivax (Pv) malaria is increasingly recognized as a significant cause of severe malaria in pediatric populations.
- Understanding the spectrum of severe manifestations is essential for effective clinical management.
Purpose of the Study:
- To retrospectively analyze and describe the diverse severe clinical, hematological, and biochemical manifestations of Plasmodium vivax malaria in children.
- To highlight the potential severity and unusual complications associated with Pv malaria.
Main Methods:
- Retrospective analysis of medical records of children (0-18 years) diagnosed with Pv malaria monoinfection.
- Inclusion criteria: confirmed Pv malaria via peripheral blood film and/or rapid diagnostic test (RDT).
- Analysis of clinical presentations, hematological parameters, and biochemical markers.
Main Results:
- Twenty-three pediatric patients with Pv malaria were analyzed.
- High prevalence of severe anemia (34%), thrombocytopenia (96%), and cerebral malaria (3 cases).
- Significant rates of liver dysfunction (17.3%), jaundice, and renal dysfunction (26%) were observed, with one fatal outcome.
Conclusions:
- Plasmodium vivax malaria can present with unusual and life-threatening complications in children.
- The designation 'Severe Vivax Malaria' should be considered as a distinct clinical entity in medical guidelines.
- Further research is warranted to elucidate the etiopathogenesis and optimize treatment strategies for severe Pv malaria.
Unlabelled:
Plasmodium vivax (Pv) malaria is being increasingly recognized as a cause of severe malaria in children.
Objectives:
To describe the various severe manifestations associated with vivax malaria by retrospective analysis of records.
Methods:
Children between the ages of 0 and 18 years with a confirmed diagnosis of Pv malaria monoinfection done by peripheral blood film (PBF) and/or rapid diagnostic test (RDT) admitted between June and September 2009 were included. Their clinical, hematological and biochemical manifestations were analyzed.
Results:
Twenty-three patients of Pv malaria were retrospectively analyzed. Thrombocytopenia was present in 22 (96%) patients with counts less than 50,000/ μL in 9 patients. Severe anemia (hgb<5mg/dl) was present in 8 (34%) patients. Cerebral malaria was present in 3 patients. Liver enzymes were elevated (>3 times normal) in 4 (17.3%) patients while jaundice (bilirubin>2.5mg/dl) was present in 2 patients (total bilirubin 5.2mg/dl and 14.3mg/dl). Renal dysfunction (creatinine>3mg/dl) was present in 6 (26%) patients with 2 patients showing severely deranged renal functions (blood urea 168 mg/dl, 222 mg/dl and serum creatinine 5.0mg/dl, 5.6 mg/dl, respectively). Hypernatremia was present in one patient. One patient expired within 12h of presentation because of severely deranged hepatic and renal dysfunction.
Conclusion:
Pv malaria can lead to unusual and fatal complications. All new guidelines should include "Severe Vivax malaria" as a clinical entity. Further research into the etiopathogenesis and treatment would be important.
