Relation between Increased IL-10 Levels and Malaria Severity: A Systematic Review and Meta-Analysis

Area of Science:

• Immunology
• Infectious Diseases
• Pathogenesis

Background:

• Anti-inflammatory cytokines are implicated in severe malaria pathogenesis.
• The specific role of Interleukin-10 (IL-10) in severe malaria remains incompletely understood.

Purpose of the Study:

• To systematically review and meta-analyze studies comparing IL-10 levels in severe versus non-severe malaria patients.
• To clarify the association between IL-10 levels and malaria severity.

Main Methods:

• Systematic literature search of PubMed, Scopus, and Embase.
• Quality assessment using Strengthening the Reporting of Observational Studies in Epidemiology guidelines.
• Meta-analysis using a random-effects model.

Main Results:

• 19 studies involving 1215 participants were included.
• Patients with severe malaria showed significantly higher IL-10 levels (SMD: 0.74, p=0.03).
• High heterogeneity (I²=97.22%) was observed across studies.

Conclusions:

• Meta-analysis indicates elevated IL-10 levels in severe malaria.
• Further research is needed to confirm these findings due to heterogeneity.
• Investigating IL-10 in combination with other markers may offer alternative severe malaria indicators.
