RESUMO
Nontyphoidal Salmonella infections often present with self-limited gastroenteritis. Extraintestinal focal infections are uncommon but have high mortality and morbidity. Urinary tract infection caused by nontyphoidal Salmonella is usually associated with structural abnormalities of the urinary tract. Nephrocalcinosis and nephrolithiasis are the major risk factors. Although primary hyperparathyroidism has been reported to increase the risk of nephrocalcinosis and nephrolithiasis, little is known about the association between hyperparathyroidism and Salmonella urinary tract infection. We report the case of a 37-year old man who had a history of primary hyperparathyroidism and bilateral nephrocalcinosis and who developed urinary tract infection. Salmonella Group D was isolated from his urine specimen. Salmonella should be considered as a possible causality organism in patients with primary hyperparathyroidism and nephrocalcinosis who develop urinary tract infection. These patients need to be aware of the potential risks associated with salmonellosis.

Las infecciones por Salmonella no tifoidea se presentan a menudo con gastroenteritis auto-limitada. Las infecciones extra-intestinales focales son poco frecuentes, pero tienen una alta mortalidad y morbilidad. La infección de las vías urinarias causada por la Salmonella no tifoidea se asocia generalmente a anomalías estructurales de las vías urinarias. La nefrocalcinosis y la nefrolitiasis son los principales factores de riesgo. Aunque se ha reportado que el hiperparatiroidismo primario aumenta el riesgo de la nefrocalcinosis y la nefrolitiasis, poco se sabe sobre la asociación entre el hiperparatiroidismo y la infección de las vías urinarias por Salmonella. Damos a conocer aquí el caso de un hombre de 37 años con una historia de hiperparatiroidismo primario y nefrocalcinosis bilateral, que desarrolló una infección de las vías urinarias. La Salmonella del grupo D fue aislada de su muestra de orina. La Salmonella se debe considerar como un posible organismo de causalidad en pacientes con hiperparatiroidismo primario y nefrocalcinosis que desarrollan infección del tracto urinario. Estos pacientes necesitan tomar conciencia de los riesgos potenciales asociados con la salmonellosis.
