From: Clostridium difficile infection among hospitalized HIV-infected individuals: epidemiology and risk factors: results from a case-control study (2002-2013)

Variable OR (95% CI) P
Acid suppressants 1.23 0.67-2.26 0.49
Previous hospitalization (<8 weeks) 1.69 0.92-3.11 0.09
Antibiotic exposure 2.02 0.83-4.91 0.12
CD4 cell count on admission 0.99 0.99-1.00 0.25
Charlson score 1.02 0.94-1.12 0.53
Serum Creatinine on admission (mg/dl) 1.09 0.86-1.39 0.45
Serum Albumin on admission (g/dl) 0.61 0.39-0.96 0.03*
Gammaglobulins on admission (g/dl) 0.68 0.48-0.96 0.03*
  1. Antibiotic exposure was evaluated until the development of diarrhea among cases and until hospital discharge for controls. CI: confidence intervals; OR: odds ratio; * p < 0.05.
