This study sought to find the risk factors for primary bacteremia, endovascular infection, and in-hospital death for patients without acquired immunodeficiency syndrome who have nontyphoid salmonellosis. From September 1995 through September 2001, 301 patients with nontyphoid salmonellosis were admitted to our hospital; of these patients, 121 had primary bacteremia, and 28 had endovascular infection. Of the 121 patients with primary bacteremia, 64 were aged >50 years, and 26 had endovascular infection. Overall, 90 patients (29.9%) had immunodeficiency. Predictors of primary bacteremia were age; presence of systemic lupus erythematosus; group B, group C, or group D Salmonella infection; and immunodeficiency. The positive predictor of endovascular infection in adult patients with primary bacteremia was group C Salmonella infection, and negative predictors were immunodeficiency and solid-organ cancer. The overall in-hospital mortality rate was 12%; for primary bacteremia, it was 24.8%; for endovascular infection, it was 14.3%. Predictors of in-hospital death were age, extraintestinal infection, and solid-organ malignancy.
