Community acquired pneumonia (CAP) is a common reason for hospitalization and death in elderly people. Many predictors of in-hospital outcome have been studied in the general population with CAP. However, data are lacking on the prognostic significance of conditions unique to older patients, such as delirium and the coexistence of multiple comorbidities. The aim of this study was to evaluate predictors of in-hospital outcome in elderly patients hospitalized for CAP. In this retrospective study, consecutive patients with CAP aged ≥65 years were enrolled between January 2011 and June 2012 in two general wards. Clinical and laboratory characteristics were collected from electronic medical records. The end-point of the study was the occurrence of in-hospital death. 443 patients (mean age 81.8 ± 7.5, range 65–99 years) were enrolled. More than 3 comorbidities were present in 31 % of patients. Mean confusion, blood urea nitrogen, respiratory rate, blood pressure and age ≥65 years (CURB-65) score was 2.5 ± 0.7 points. Mean length of stay was 7.6 ± 5.7 days. In-hospital death occurred in 54 patients (12.2 %). At multivariate analysis, independent predictors of in-hospital death were: chronic obstructive pulmonary disease (COPD) (OR 6.21, p = 0.005), occurrence of at least one episode of delirium (OR 5.69, p = 0.017), male sex (OR 5.10, p < 0.0001), and CURB-65 score (OR 3.98, p < 0.0001). Several predictors of in-hospital death (COPD, male gender, CURB-65) in patients with CAP older than 65 years are similar to those of younger patients. In this cohort of elderly patients, the occurrence of delirium was highly prevalent and represented a distinctive predictor of death.

The anti-tumor necrosis factor (TNF) agents are drugs that in recent years turned out to be a mainstay of therapy for the treatment of inflammatory bowel disease. Nevertheless, they have several adverse effects such as infectious complications and immunogenicity. One of the most common immunogenic effects is the development of autoantibodies, mainly anti-nuclear antibodies and anti-double-stranded DNA antibodies, only rarely associated with overt clinical manifestations of systemic lupus erythematosus. Adalimumab is a fully humanized monoclonal antibody widely used for the treatment of Crohn's disease and supposed to have less immunogenic activity and a safer profile than other anti-TNF agents. The occurrence of systemic lupus erythematosus with involvement of the central nervous system appears to be a very rare complication of such drugs, and no cases have been reported in the medical literature in patients treated with adalimumab. We report a case of a 53 years-old woman with ileo-colic Crohn's disease where the treatment with adalimumab was complicated by systemic lupus erythematosus with central nervous system vasculitis.
