Abstract

RÉSUMÉ
Purple urine bag syndrome (PUBS) is a sign of urinary infection characterized by a purple staining of the urinary catheter and the urine collector by pigments resulting from the degradation of dietary tryptophan by intestinal and urinary bacteria. It is a benign syndrome but can manifest itself with complications under certain conditions. We report a case of PUBS revealed by a state of septic shock. A patient HM with a history of high blood pressure (hypertension) and stroke with left hemiplegia, bedridden for the last six months was admitted to internal medicine for her bedridden condition, anorexia, and significant weight loss. Twelve days after admission, her clinical condition deteriorated with the onset of septic shock and a change in the urine bag colour to purple. The urinary strip showed a urinary pH at 8.3, leukocyturia (2+) with nitrite (1+) and proteinuria (2+). Urine cytobacteriological examination showed leucocyturia > 104/ml, bacteriuria > 105uF/ml and the presence of K.pneumoniae sensitive to ceftriaxone. Management was based on antibiotic therapy and medical resuscitation. The patient died during resuscitation. Although PUBS is considered benign, the clinician should keep in mind the existence of life-threatening severe forms.

ABSTRACT
Le syndrome du sac urinaire violet (PUBS) est un signe d'infection urinaire caractérisé par une coloration violette de la sonde urinaire et du collecteur d'urine par des pigments résultant de la dégradation du tryptophane alimentaire par des bactéries intestinales et urinaires. Il s'agit d'un syndrome bénin mais qui peut se manifester par des complications dans certaines conditions. Nous rapportons un cas de PUBS révélé par un état de choc septique. Une patiente HM ayant des antécédents d'hypertension et d'accident vasculaire cérébral avec hémiplégie gauche, alitée depuis six mois, a été admise en médecine interne pour son état alité, son anorexie et sa perte de poids importante. Douze jours après son admission, son état clinique s'est détérioré avec l'apparition d'un choc septique et un changement de couleur de la poche d'urine qui est passée au violet. La bandelette urinaire montrait un pH urinaire de 8,3, une leucocyturie (2+) avec nitrite (1+) et une protéinurie (2+). L'examen cytobactériologique des urines a montré une leucocyturie > 104/ml, une bactériurie > 105uF/ml et la présence de K.pneumoniae sensible à la ceftriaxone. La prise en charge a été basée sur l'antibiothérapie et la réanimation médicale. Le patient est décédé pendant la réanimation. Bien que le PUBS soit considéré comme bénin, le clinicien doit garder à l'esprit l'existence de formes graves potentiellement mortelles.
