Unveiling glomerulonephritis in the Pacific: a Fijian cohort study

Area of Science:

• Nephrology
• Epidemiology
• Global Health

Background:

• Kidney disease epidemiology is under-documented in the Pacific Islands.
• Establishing diagnostic services for kidney diseases is challenging in resource-limited settings.

Purpose of the Study:

• To investigate the incidence, distribution, and patterns of biopsy-proven glomerulonephritis (GN) in Fiji.
• To describe the experience of organizing a kidney biopsy service in a resource-limited environment.

Main Methods:

• Retrospective analysis of native kidney biopsies performed in Fiji's public sector (2019-2023).
• Inclusion criteria focused on glomerulonephritis diagnoses; exclusion of non-diagnostic or non-glomerular biopsies.
• Data collection included patient demographics, clinical indications, and diagnostic findings, primarily via light microscopy.

Main Results:

• An average crude biopsy rate of 31.6 per million population was observed.
• Glomerulonephritis was diagnosed in 121 of 142 biopsies, with lupus nephritis (43%) and diabetic nephropathy (19%) being most common.
• Nephrotic syndrome was the leading indication for biopsy (38.8%).

Conclusions:

• A kidney biopsy service is crucial for diagnosing GN in resource-limited settings like Fiji.
• The study demonstrates the feasibility of such a service, though diagnostic yield requires improvement.
• Further efforts are needed to enhance diagnostic capabilities and expand the service's reach.
