Salmonella bacteremia in systemic lupus erythematosus. Eight-year experience at a municipal hospital.
Non-endemic Salmonella bacteremia tends to occur in patients with chronic disease. We reviewed all cases of Salmonella infection documented in adults at Bellevue Hospital during the years 1975-1982. Unexpectedly, the most frequent underlying disease found among bacteremic patients was systemic lupus erythematosus ( SLE). Patients with SLE accounted for 6 of 30 Salmonella bacteremias as compared with 13 of 2,388 non-Salmonella gram-negative bacteremias. Salmonella was the single most frequent gram-negative isolate from the blood of SLE patients. All lupus patients with Salmonella infection were bacteremic. In contrast, isolates from blood represented only 23% of all Salmonella infections documented in the non-lupus population. Presentation was characterized by fever (greater than 103 degrees F) and abdominal pain. Four of the 6 patients were hypocomplementemic. All were receiving immunosuppressive therapy. We conclude that SLE patients in a municipal hospital setting are at increased risk for Salmonella sepsis. This should be considered when empiric antibiotic therapy is initiated.[1]References
