Abnormalities of Kidney Function in Acute Malarial and non-Malarial Infections

Area of Science:

• Tropical medicine
• Nephrology
• Infectious diseases

Background:

• Malaria and non-malarial infections cause high morbidity and mortality in tropical regions.
• Acute malaria can lead to multi-organ dysfunction, particularly affecting the kidneys.
• Early identification of kidney dysfunction in malaria is vital for improving patient care and reducing mortality.

Purpose of the Study:

• To determine the spectrum of kidney dysfunction in patients with acute malaria.
• To compare kidney dysfunction in acute malaria versus non-malarial infections.
• To identify specific renal abnormalities associated with acute malaria.

Main Methods:

• Prospective observational study design.
• Inclusion criteria: acute malaria (parasite density ≥1000/µl, falciparum species), acute non-malarial infection, or healthy controls.
• Assessment of renal parameters: urea, creatinine, eGFR, albuminuria, electrolytes, and acute kidney injury (AKI).

Main Results:

• Electrolyte abnormalities observed in acute falciparum malaria: hyponatremia (10.7%), hypernatremia (4.0%), hypokalemia (8.0%), hyperkalemia (13.3%).
• Mean serum creatinine was significantly different across groups (p=0.023), with acute malaria patients showing 1.0±0.3 mg/dl.
• Transient albuminuria noted in 6.7% of acute malaria patients, resolving post-infection.

Conclusions:

• Acute malaria is associated with a higher frequency of serum electrolyte abnormalities and albuminuria compared to non-malarial infections.
• Renal abnormalities in acute malaria warrant close monitoring and management.
• Findings highlight the importance of assessing kidney function in malaria patients.
