AB  - Sjogren’s syndrome (SS) is an autoimmune disease with involvement of multiple organs, including both glandular and extraglandular organs. Usually involvement of glandular organs manifests before the extraglandular ones, but when the sequence is reversed, diagnosis may be missed. Hypokalaemic quadriparesis in SS is not uncommon. Respiratory failure in hypokalaemia is not usually seen, but in SS, it has been reported. We report a case of a 55-year-old woman who presented with sudden onset flaccid quadriparesis and respiratory muscle paralysis secondary to severe hypokalaemia. On detailed investigation, she was detected to have distal renal tubular acidosis secondary to clinically inapparent and asymptomatic SS.
