Abstract
Sjogren syndrome (SS) is a systemic autoimmune disorder with predominant exocrine gland involvement leading to sicca symptoms. Among extraglandular manifestations, renal disease is the most common. Tubular interstitial nephritis and renal tubular acidosis (RTA) are the common presentations. Mild hypokalemia associated with distal RTA is common in SS, however, severe hypokalemia causing paralysis is unusual. We report the case of a 26-year-old female who presented with hypokalemic paralysis. On evaluation, distal RTA was diagnosed. Further evaluation showed positive SS-a/SS-b antibodies in high titer, which confirms the diagnosis of primary SS. Our report illustrates that SS is a rare but important cause of hypokalemic paralysis. Résumé syndrome de Sjogren (SS) est une maladie auto-immune systémique avec une atteinte prédominante des glandes exocrines entraînant des symptômes de sicca. Parmi manifestations extraglandulaires, la maladie rénale est la plus courante. La néphrite interstitielle tubulaire et l'acidose tubulaire rénale (RTA) sont les présentations. Une hypokaliémie légère associée à un RTA distal est courante dans les SS, cependant, une hypokaliémie sévère provoquant une paralysie est inhabituelle. Nous rapportons le cas d'une femme de 26 ans qui présentait une paralysie hypokaliémique. À l'évaluation, un RTA distal a été diagnostiqué. Plus loin l'évaluation a montré des anticorps SS-a / SS-b positifs à titre élevé, ce qui confirme le diagnostic de SS primaire. Notre rapport montre que SS est un cause rare mais importante de paralysie hypokaliémique.Keywords
