Simultaneous Presentation of Minimal Change Disease and Tubulointerstitial Nephritis Associated with Primary Sjögren's Syndrome and Hashimoto's Thyroiditis.

A 78-year-old woman experienced systemic edema and was diagnosed with nephrotic syndrome and Hashimoto's thyroiditis (HT). A renal biopsy revealed minimal change disease (MCD) and tubulointerstitial nephritis, which resulted in the diagnosis of primary Sjögren's syndrome (PSS). PSS and HT can be complicated with MCD; however, there are no published case reports of MCD presenting with both conditions simultaneously. We aimed to inform nephrologists and rheumatologists about this rare condition through a literature review of renal outcomes in patients with MCD associated with PSS and HT.
