What causes chronic kidney disease in farming communities in Central America

Exploring risk factors and predictors of endemic CKDu in agricultural regions of four Central America countries

NIH-funded research Universidad Nacional, Costa Rica · NIH-11403180

This project looks for causes and early warning signs of a common chronic kidney disease that affects young agricultural workers in Costa Rica, Panama, Nicaragua, and Guatemala.

What this research studies

You would be followed over time along with other people from rural agricultural communities to see how kidney function changes. The team will collect health information, work and living conditions, and samples such as blood and other biospecimens. They will record heat exposure, infections, and possible chemical exposures, and store samples for genetic and biomarker testing through the CURE consortium. The goal is to find risk factors and early markers that predict worsening kidney function.

Who could benefit from this research

Good fit: Ideal candidates are people living or working in rural agricultural areas of Costa Rica, Panama, Nicaragua, or Guatemala—including young adults and sugarcane or other field workers—with or without known CKDu.

Not a fit: People who live outside the study regions or whose kidney disease has a known cause unrelated to agricultural exposures may not benefit directly from this project.

Why it matters

Potential benefit: If successful, the project could help prevent illness by identifying causes and early warning signs so people can get earlier care or safer working conditions.

How similar studies have performed: Previous research has pointed to heat stress, work strain, and possible chemical exposures as contributors, but causes remain unclear, and this multi-country, long-term approach with biomarker collection is a more comprehensive effort.
