What is CKDu, and why does Uddanam matter?

"CKDu manifests in otherwise healthy individuals — without diabetes, hypertension, or glomerular disease — indicating a distinct and poorly understood disease pathway."

Chronic Kidney Disease of Unknown Etiology has become an escalating public health crisis in coastal Andhra Pradesh, particularly in the Uddanam region of Srikakulam District. Unlike conventional CKD, it strikes working-age individuals with no prior risk factors, making early detection and causal identification an urgent priority.

Current evidence strongly associates CKDu onset with environmental and occupational exposures — pesticides, heavy metals, fluoride and silica — compounded by heat stress and lifestyle factors specific to this agricultural community.

Research Phases
1
Enrollment & Baseline Data
Community screening, participant registration
2
Sample Collection & Lab Analysis
Water, soil, blood, urine, kidney tissue
3
Biomarker Validation
Clinical, metabolic, and metabolomics markers
4
Prevention Framework
Community-level risk strategies

Three pillars of investigation

Each objective builds toward a comprehensive understanding of CKDu — from exposure to detection to prevention.

Environmental & Occupational Risk Assessment

Comprehensively evaluate exposure to pesticides, heavy metals, fluoride and silica across water, soil, blood, urine and kidney tissue samples from the Uddanam population.

Pesticides Heavy Metals Fluoride Silica
Novel Biomarker Identification

Identify and validate clinical and metabolic biomarkers — including blood, urine, and urinary metabolomics signatures — for early detection, disease staging, and long-term monitoring.

Metabolomics Early Detection Disease Staging
Community Risk Framework

Integrate exposure and biomarker data into a unified risk assessment model that informs targeted, community-level preventive interventions in Srikakulam District.

The Uddanam Region of Srikakulam

Uddanam — a coastal belt in Srikakulam District — has witnessed an alarming rise in CKDu cases over the past two decades, disproportionately affecting agricultural workers and their families. This study is anchored in this community.

High density of CKDu cases concentrated in coastal farming communities
Occupational exposure to agrochemicals and contaminated groundwater a key concern
Study encompasses water, soil, and biological sample collection from across the region
