Patients with immunosuppression are at increased risk for occurrence, delayed diagnosis, and progression of AE.

TTP provides reliable information in patients with S. aureus bacteraemia, on the risk of IE, and prognosis, with short TTP being an independent predictor of death. These data, readily available at no cost, may be used to identify patients who require specific attention.

BackgroundAspecific scoring systems are used to predict the risk of death postsurgery in patients with infective endocarditis (IE). The purpose of the present study was both to analyze the risk factors for in‐hospital death, which complicates surgery for IE, and to create a mortality risk score based on the results of this analysis.Methods and ResultsOutcomes of 361 consecutive patients (mean age, 59.1±15.4 years) who had undergone surgery for IE in 8 European centers of cardiac surgery were recorded prospectively, and a risk factor analysis (multivariable logistic regression) for in‐hospital death was performed. The discriminatory power of a new predictive scoring system was assessed with the receiver operating characteristic curve analysis. Score validation procedures were carried out. Fifty‐six (15.5%) patients died postsurgery. BMI >27 kg/m2 (odds ratio [OR], 1.79; P=0.049), estimated glomerular filtration rate <50 mL/min (OR, 3.52; P<0.0001), New York Heart Association class IV (OR, 2.11; P=0.024), systolic pulmonary artery pressure >55 mm Hg (OR, 1.78; P=0.032), and critical state (OR, 2.37; P=0.017) were independent predictors of in‐hospital death. A scoring system was devised to predict in‐hospital death postsurgery for IE (area under the receiver operating characteristic curve, 0.780; 95% CI, 0.734–0.822). The score performed better than 5 of 6 scoring systems for in‐hospital death after cardiac surgery that were considered.ConclusionsA simple scoring system based on risk factors for in‐hospital death was specifically created to predict mortality risk postsurgery in patients with IE.

Patients co-infected with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) are particularly at risk of hepatitis B reactivation. Two cases of patients infected with HIV with isolated anti-HBc antibodies who had experienced an HBV reactivation are described. In the two cases HBV reactivation occurred after withdrawal of anti-retroviral treatment with anti-HBV activity from the patients' highly active antiretroviral therapy (HAART), in accordance with HIV genotypic resistance profiles. Consequently, plasma samples from 383 patients infected with HIV were tested to assess the prevalence of occult HBV infection in the Infectious Diseases Department Unit of Nancy Hospital by investigating serological patterns and HBV replication. Forty-five percent (172/383) of patients had had previous contact with HBV. Isolated anti-HBc antibodies were observed in 48 patients (48/383, 12%) and, among these, 2 were HBV-DNA positive. Since 75% (288/383) of the patients were treated with HAART, including at least one drug active against HBV, occult HBV infection was perhaps unrecognized. In cases of HIV infection, all patients should be screened for HBV infection and the knowledge of HBV status as well as the monitoring of HBV viral load are essential in preventing HBV reactivation. Consideration should be given to the continuation of drugs with anti-HBV activity in co-infected patients receiving HAART, as cessation of therapy is associated with a risk of HBV reactivation. At least, close monitoring of the HBV viral load is warranted in such situations.
