Brief Summary:
The present protocol seeks to advance our understanding of sclerosing glomerular and tubulointerstitial kidney diseases including but not limited to variants of focal segmental glomerulosclerosis FSGS and chronic kidney disease of unknown etiology CKDu This protocol will encompass studies of the natural history pathogenesis and treatment of these chronic kidney disorders It will also allow us to 1 provide second opinions to referring physicians about management of subjects with these relatively rare kidney diseases 2 collect research samples eg blood urine and kidney tissue obtained from clinically-indicated or from research renal biopsies 3 and treat these subjects with standard or other approved therapies or 4 invite selected subjects patients to participate in limited pilot studies of novel combinations of standard therapeutic agents such as rituximab and cyclosporine 5 Agricultural worker chronic kidney disease of undetermined etiology CKDu is a growing problem in tropical countries in the Americas and Asia including Sri Lanka where collaborators are located We will receive kidney tissue from 25 CKDu cases for pathologic examination and transcriptional profiling and blood plasma serum urine for metabolomic and genetic analysis from 50 cases and controls Subjects were consented and samples were collected under a protocol approved by the University of Colombo IRB These studies may provide the opportunity to generate new hypotheses regarding pathogenesis and treatment that would be candidates for testing in other research protocols
Subjects with known or suspected forms of sclerosing glomerular or chronic fibrosing tubulointerstitial kidney diseases will undergo routine medical evaluation laboratory testing imaging procedures and kidney biopsies as medically indicated Selected subjects will be invited to provide informed consent to undergo a kidney biopsy for research purposes Blood urine and tissue samples will be evaluated both for standard diagnostic purposes and for research purposes using specialized molecular methods that may provide insights into specific disease pathogenesis Subjects may elect to receive the results of their kidney disease evaluation NIH treatment recommendations and return to the care of their referring physicians Other subjects may be treated with either conventional or approved agents or with separate consent with a novel combination of conventional therapies rituximab and cyclosporine as part of pilot studies that would involve long-term follow-up care at the NIH
