We describe a 30-year-old uninsured Hispanic woman with type 1 diabetes, hypertension, and CKD3B who presented with nephrotic syndrome, sepsis, and progressive muscle weakness. Her pleural effusions, periorbital changes, elevated free light chains, and dysphagia raised concern for systemic conditions such as amyloidosis or polymyositis, especially given inconsistent outpatient follow-up. Because her management would differ significantly depending on the underlying cause and due to the high risk of loss to follow-up, a renal biopsy was pursued. Serologic studies were unremarkable, and biopsy ultimately confirmed diabetic nephrosclerosis. This case highlights how clinical findings alone may be misleading in diabetic patients with heavy proteinuria. Renal biopsy remains the most reliable tool for distinguishing diabetic nephropathy from other systemic diseases. An individualized approach that considers comorbidities and social determinants of health is essential for accurate diagnosis and care.<\/jats:p>","DOI":"10.1177\/2050313x261448376","type":"journal-article","created":{"date-parts":[[2026,5,4]],"date-time":"2026-05-04T11:43:46Z","timestamp":1777895026000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Diabetic nephropathy masquerading as systemic disease: The critical role of renal biopsy in a young uninsured woman with nephrotic syndrome"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-4740-6837","authenticated-orcid":false,"given":"Yolanda V.","family":"Gutierrez","sequence":"first","affiliation":[{"name":"School of Medicine, The University of Texas Rio Grande Valley, Edinburg, TX, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexis","family":"Vargas Del Toro","sequence":"additional","affiliation":[{"name":"School of Medicine, The University of Texas Rio Grande Valley, Edinburg, TX, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Kochi Yamamoto","sequence":"additional","affiliation":[{"name":"School of Medicine, The University of Texas Rio Grande Valley, Edinburg, TX, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-2241-3673","authenticated-orcid":false,"given":"Jose","family":"Loayza Pintado","sequence":"additional","affiliation":[{"name":"School of Medicine, The University of Texas Rio Grande Valley, Edinburg, TX, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andres","family":"Suarez Parraga","sequence":"additional","affiliation":[{"name":"School of Medicine, The University of Texas Rio Grande Valley, Edinburg, TX, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,5,4]]},"reference":[{"issue":"6","key":"e_1_3_3_2_2","first-page":"479","article-title":"Diagnosis and management of nephrotic syndrome in adults","volume":"93","author":"Kodner C.","year":"2016","unstructured":"Kodner C.
