Recurrent Severe Hyponatremia in a Patient with Sj ögren's Syndrome.

Recurrent Severe Hyponatremia in a Patient with Sjögren's Syndrome. Electrolyte Blood Press. 2020 Jun;18(1):19-22 Authors: Kim HD, Lee J, Chung BH, Yang CW, Kim YS, Park CW Abstract Sjögren's syndrome (SS) is an autoimmune disease that presents with exocrine gland dysfunction. Renal involvement is common in SS and often results in tubulointerstitial nephritis, renal tubular acidosis, and Fanconi's syndrome. Electrolyte imbalances are commonly the first symptom of renal involvement of SS. The most common feature of dysnatremia in SS is hypernatremia with diabetes insipidus. However, cases of hyponatremia with syndrome of inappropriate antidiuretic hormone secretion (SIADH) are rarely reported in patients with SS. Herein, we report a case of recurrent severe SIADH in a patient with SS. PMID: 32655653 [PubMed]
