Un caso de Síndrome de Sjõgren primario complicado con acidosis tubular renal tipo 1 / Sjõgren syndrome associated with renal tubular acidosis type I

Primary Sjõgren's Syndrome complicated with a renal tubular acidosis type 1 and hypocalcemic paralysis, as the principal clinical manifestation, is uncommon. Although the initial manifestations of the nephropathy are not well understood, it is believed that the invasion of mononuclear cells and the high level of circulating antibodies, play an important role in the pathogenesis of the disease. We present a patient with hypocalcemic paralysis as an initial manifestation of a latent Sjõgren's disease. The glandular biopsy was normal, suggesting a mayor participation of an immunological humoral factor in the renal lesion.
