Predictive factors for the neutralizing antibody response following pre-exposure rabies immunization: validation of a new booster dose strategy.

A prospective cohort of 312 subjects who received pre-exposure rabies immunization and who were monitored serologically with a 10-year follow-up was assessed using multivariate analysis. The aim was to propose a new booster dose strategy by identifying predictive factors for the durability of the neutralizing antibody response. Evaluation bore on several factors relating to: (1) demographic characteristics: age, gender; (2) vaccines: type of vaccine (HDCV or PVRV), injection regimen (D0-D28-D365 or D0-D7-D28-D365) and vaccine lots' antigenic potency; and (3) resulting antibody titers. Logistic regression analysis enabled the authors to establish a predictive model for immunized subjects' serological status at ten years' follow-up expressed as a P probability for seroreversion (antibody titer <0.5 IU/ml). Highly significant factors were the immunization regimen, the type of vaccine used and the antibody titer at D379. A P value <0.4 identified subjects as "good" responders who were sure to be have satisfactory antibody titers at 10 years and who required a single booster dose every 10 years. A P value >/=0.4 identified subjects as "poor" responders in whom a specific follow-up and booster dose strategy is proposed. This new immunization strategy could at least be applied to subjects with a frequent risk of exposure, as defined by institutional recommendations. This new immunization strategy should nevertheless undergo an external validation and a cost-effectiveness evaluation.

Relationships between work and HIV/AIDS status.

The aim of this study was to assess reasons contributing to a cessation of occupational activities in HIV-infected persons. One hundred patients were studied, 55 of whom were working at the time of the study while 45 were unemployed. Twenty of the patients had been diagnosed as having AIDS and the remaining patients were HIV-positive. The main causes of work cessation were psychological, not physical, symptoms. Disclosure of HIV status to work colleagues or employers does not seem to have an effect on employment.

Evaluation of the fungitest kit by using strains from human immunodeficiency virus-infected patients: study of azole drug susceptibility.

One hundred eighteen Candida clinical isolates from human immunodeficiency virus-infected patients were tested for their susceptibilities to fluconazole and itraconazole by Fungitest and the National Committee for Clinical Laboratory Standards MIC method. Fungitest results depended on both yeast species and antifungal agents. This test is able to detect sensitive strains (97% agreement with results of the MIC method in tests with fluconazole and 84% agreement in tests with itraconazole) but has a poor capacity to detect resistant strains (26% agreement in tests with fluconazole and 5% agreement in tests with itraconazole).

[Diagnostic criteria of infectious endocarditis].

Accurate diagnostic criteria for infective endocarditis are essential to epidemiological studies. The von Reyn's criteria have been widely used for more than a decade after they were published in 1981. In 1994, the Duke's criteria for the clinical diagnosis of infective endocarditis were published, incorporating echocardiographic findings. They are modeled after the Jones criteria for the identification of cases of rheumatic fever and include 2 major and 6 minor diagnostic criteria. They are about twice as specific as the former von Reyn's criteria, without loss of specificity, and should become a standard reference for diagnosing infective endocarditis.

[Breast tuberculosis. A case of a diffuse inflammatory form].

We report a case of inflammatory tuberculosis of the breast in a 83-year-old French Caucasian woman. She presented with a diffuse inflammatory tuberculosis of the breast and an axillary enlarged lymph node but no tumor was palpable in the breast. A carcinoma was firstly suspected. The diagnosis was accessed after repeat punction of a lymph node, as a Mycobacterium tuberculosis was identified after culture. A medical treatment was sufficient in our case.

The Duke criteria for diagnosing infective endocarditis are specific: analysis of 100 patients with acute fever or fever of unknown origin.

The recently proposed Duke criteria were confirmed to be more sensitive than the former Beth Israel criteria for the diagnosis of infective endocarditis (IE). To assess the specificity of the Duke criteria, we reviewed the records of 100 patients admitted to two internal medicine wards because of acute fever or fever of unknown origin (FUO). IE was considered a possible diagnosis for all patients who had had at least two blood cultures performed and one transthoracic echocardiogram obtained. The diagnosis of IE was rejected in all cases in accordance with the Duke criteria (i.e., a firm alternate diagnosis [n = 23], resolution of symptoms with no antibiotics [n = 39], or both reasons [n = 38]). To calculate the specificity of the Duke criteria, all 100 cases were then reclassified according to these criteria as if the diagnosis of IE had not been rejected. Only one patient, who probably did not have IE, was reclassified as having clinically definite IE. The specificity of the Duke criteria could therefore be calculated to 0.99 (95% confidence interval, 0.97-1). Although the design of the study may have resulted in a slight overestimation of the specificity rate, we conclude that the Duke criteria are highly specific for ruling out IE in patients with acute fever or FUO who are at low risk for IE.
