Scrub typhus: A rare cause of secondary nephrotic syndrome

Area of Science:

• Tropical medicine
• Pediatric nephrology
• Infectious diseases

Background:

• Scrub typhus is a significant cause of acute febrile illness in tropical regions, particularly after monsoon seasons.
• Untreated scrub typhus can lead to severe complications, including acute kidney injury.
• Secondary nephrotic syndrome in children is often linked to infections like malaria, syphilis, and HIV.

Observation:

• This report details a rare case of a five-year-old girl diagnosed with scrub typhus.
• The patient presented with nephrotic syndrome and acute kidney injury.
• The case highlights an infrequent association between scrub typhus and nephrotic syndrome.

Findings:

• Scrub typhus was identified as the cause of nephrotic syndrome and acute kidney injury in the pediatric patient.
• The patient experienced a complete recovery, indicating a favorable outcome is possible with appropriate management.
• This case adds to the limited evidence of scrub typhus-induced nephrotic syndrome.

Implications:

• Reinforces the importance of considering scrub typhus in the differential diagnosis of febrile illness with renal complications in endemic areas.
• Highlights the potential for scrub typhus to cause nephrotic syndrome, a complication previously reported only once.
• Suggests that prompt diagnosis and treatment of scrub typhus can lead to favorable outcomes even in complex cases involving acute kidney injury and nephrotic syndrome.
