Crimean-Congo hemorrhagic fever among health care workers, Turkey.

We investigated 9 cases of Crimean-Congo hemorrhagic fever (1 fatal, 2 asymptomatic) among health care workers in Turkey. Needlestick injuries were reported for 4 workers. Eight received ribavirin. In addition to standard precautions, airborne infection isolation precautions are essential during aerosol-generating procedures. For postexposure prophylaxis and therapy, ribavirin should be given.

Severity scoring index for Crimean-Congo hemorrhagic fever and the impact of ribavirin and corticosteroids on fatality.

BACKGROUND: Patients infected with Crimean-Congo hemorrhagic fever (CCHF) virus present with a wide clinical spectrum. In observational studies, the effects of therapeutic agents are confounded by severity. We describe use of a clinical severity scoring index (SSI) for CCHF patients and assess the effect of ribavirin and corticosteroid therapy on the case-fatality rate, stratified by SSI. METHODS: The study group included hospitalized patients who received a diagnosis of CCHF at the Infectious Diseases and Clinical Microbiology Clinic of Ankara Numune Education and Research Hospital between 2004 and 2011. The SSI included platelet count, bleeding, fibrinogen level, activated partial thromboplastin time, and somnolence. The effects of ribavirin and corticosteroid on the case-fatality rate were studied by univariate and multivariate analysis, stratified by SSI. RESULTS: Two hundred eighty-one confirmed cases of CCHF were included in the study. Of 281 patients, 23 (8%) died. The mean age (±SD) of the patients was 47 ± 16 years. Forty-nine percent were female. The mean duration of stay at our clinic after onset of symptoms was 4.4 days, with a range of 1-14 days. In multivariate analysis of factors for the prediction of death, the SSI (odds ratio [OR], 3.27; 95% confidence interval [CI], 2.09-5.13) and ribavirin use (OR, 0.04; 95% CI, .004-.48) were found to be statistically significant factors. CONCLUSION: The SSI is an accurate predictor of death and will therefore be a useful tool for case management and for drug-assessment studies. After stratification of cases by SSI, ribavirin was found to be effective in reducing the case-fatality rate, especially among moderately ill patients, whereas steroids were found to be beneficial particularly among patients with severe disease.

Evaluation of tularemia cases focusing on the oculoglandular form.

INTRODUCTION: Tularemia is a zoonotic disease caused by Francisella tularensis. The oculoglandular form is one of the rarest forms. In this study, evaluated tularemia patients, focusing on the ocular form and the efficacy of early antibiotic therapy. METHODOLOGY: During a tularemia outbreak, the epidemiological and clinical findings, laboratory assays, and drugs used for the treatment of 48 patients were recorded prospectively. The diagnosis of tularemia was confirmed with microagglutination test (MAT) as well as clinical findings. RESULTS: The mean age of the subject was 48.6 years; 23 (47.9%) of them were female. Thirty-six (81.25%) patients had clinical presentation compatible with oropharyngeal tularemia, seven (14.58%) with oculoglandular tularemia, and two (4.1%) with ulceroglandular tularemia. The most common symptoms were fever (91.6%) and sore throat (81.2%), and the most common findings were lymphadenopathy (91.6%) and tonsillopharyngitis (81.2%). In the oculoglandular form, fever, lymphadenopathy, periorbital edema, conjunctival injection, and chemosis were found. The most distinctive ophthalmic feature was follicular conjunctivitis and conjunctival epithelial defects. Forty-five cases had positive serological results with MAT. All the patients were treated with antibiotics considered effective against F. tularensis, and topical antimicrobial treatment was given to the patients with oculoglandular tularemia. Twenty-six (54.16%) patients, who were admitted within three weeks of the onset of symptoms, recovered without sequel. CONCLUSIONS: During tularemia outbreaks, ocular involvement should be considered carefully. The early administration of appropriate treatment will be more effective in resolving the infection and preventing complications. Along with systemic antibiotic therapy, topical treatment will help recovery.
