Asymptomatic Salmonella enteritidis bacterial ascites

Spontaneous Bacterial Peritonitis Secondary to Salmonella spp. in a Patient With Decompensated Liver Cirrhosis

Spontaneous bacterial peritonitis (SBP) is a common and serious complication of cirrhosis, with gram-negative bacteria being the culprit in most cases. SBP secondary to Salmonella spp. is rare. Here, we report a case of Salmonellaenterica SBP in a patient with decompensated cirrhosis, diagnosed via paracentesis coupled with ascitic fluid analysis and culture. A high index of suspicion must be maintained for atypical causes of SBP, with prompt initiation of treatment.

Spontaneous non-typhoidal Salmonella peritonitis in patients with serious underlying disorders

Non-typhoidal Salmonella is a rare cause of spontaneous bacterial peritonitis (SBP). Non-typhoidal Salmonella SBP has been reported in patients with relatively normal ascitic fluid protein levels. Five patients with non-typhoidal Salmonella SBP and a review of the literature are reported. These patients had chronic underlying disorders, such as malignancy, or other conditions causing immunosuppression. In previous reports, an ascitic fluid protein level above 1.5 g/dl was present in six patients, and under 1.5 g/dl in two. In the present report, ascitic fluid protein is above 2.5 g/dl in three patients and under 1.5 g/dl in one. Immunosuppression and the virulence of the organism seem to play a major role in non-typhoidal Salmonella SBP. Physicians should be alert to the possibility of non-typhoidal Salmonella infection in patients with SBP and normal protein levels in ascitic fluid.
