Circulating Immune Complexes and Glucose-6-Phosphate Dehydrogenase Deficiency Predict Recurrent Blackwater Fever in Ugandan Children With Severe Malaria
To evaluate the association between serum circulating immune complexes (cIC), glucose-6-phosphate dehydrogenase (G6PD) deficiency, and the occurrence and recurrence of blackwater fever in children with severe malaria.
Key Findings:
Children with severe malaria had higher cIC levels than community children (P < .001).
cIC were significantly associated with severe anemia (aOR 7.33, 95% CI 3.45–15.58), jaundice (aOR 4.31, 95% CI 1.68–11.08), and blackwater fever (aOR 5.21, 95% CI 2.06–13.18).
cIC predicted readmissions for severe malaria, severe anemia, and blackwater fever with adjusted incidence rate ratios of 2.11 (95% CI 1.33–3.34), 8.62 (95% CI 2.80–26.59), and 7.66 (95% CI 2.62–22.45) respectively.
G6PD deficiency was associated with increased cIC levels in boys (P = .01) and contributed to recurrent severe anemia and blackwater fever.
Interpretation:
Immune complexes are linked to hemolytic complications in severe malaria and predict recurrences, particularly in G6PD-deficient children, suggesting a need for targeted interventions.
Limitations:
Study limited to children aged 6 months to <4 years, which may not generalize to older populations.
Potential biases in parental reporting of symptoms like tea-colored urine.
The geographical focus on Uganda may limit the applicability of findings to other regions.
Conclusion:
The study highlights the role of immune complexes in severe malaria complications and suggests a need for further investigation into G6PD deficiency's impact on these outcomes.
