An open comparative study was undertaken in order to assess the efficacy and safety of a single dose of azithromycin in the treatment of community-acquired atypical pneumonia. A total of 100 adult patients with atypical pneumonia syndrome were randomized to receive 1.5 g of azithromycin as a single dose, or 500 mg once daily for 3 days. The presence of Mycoplasma pneumoniae, Chlamydia pneumoniae, Chlamydia psittaci, Coxiella burnetii, and Legionella pneumophila infection was diagnosed by serological tests. Control clinical examinations were performed 72 h, 10-12 days and 4 weeks after treatment initiation. Among 96 patients (48 in each group) who were evaluable for clinical efficacy M. pneumoniae infection was confirmed in 24, C. pneumoniae in nine, C. psittaci in five, C. burnetii in six, and L. pneumophila in five. Forty-seven patients (97.9%) in each group were cured. Side effects were observed in two patients in the single-dose group, and one patient in the 3-day group. In conclusion, a single 1.5 g dose of azithromycin may be an alternative to the standard 3-day azithromycin regimen in the treatment of outpatients with atypical pneumonia syndrome.
Incarcerated persons comprise about 0.4% of the Croatian population, of whom 25-30% misuse drugs. We attempted to determine the structure of the prison population, prevalence of HBV, HCV, HIV markers, co-infections with HBV, HCV and HIV and acute HBV, HCV and HIV infection. In total, 25.9% of prisoners were positive for some markers for viral hepatitis (HBV 11.3%, HCV 8.3%, HBV/HCV 6.3%). Prevalence of HBV infection in intravenous drug users (IDUs) was 26.2% (highly promiscuous group 20.4%, individuals with psychiatric diseases and personality disorders 16.0%). HCV infection in IDUs was 52.0% and 4.9% in the highly promiscuous group. HBV/HCV co-infection was registered in 34.9% of prisoners positive for HBV markers (203/582). Acute HBV infection was detected in 0.5%, and HCV in 1.2%. Only 0.15% (5/3348) of prisoners were anti-HIV positive. It appears that individuals with psychiatric diseases and personality disorders could be an additional risk population for these viral infections.
The aim of this study was to determine the difference of anti-CCP and RF between HIV positive patients and a healthy control group. The rheumatological complications in HIV positive patients are rather common and are recognized as a serious problem that requires more attention. Anti-CCP and RF are the only laboratory tools for rheumatoid disorder diagnostics and predictors of the course of the disease. We determined anti-CCP and RF in sera of 35 healthy volunteers and 45 HIV positive patients. Data were compared using chi-square test, Mann-Whitney test and ROC curve statistics. Both parameters were significantly higher in HIV positive patients, and significant differences between areas under the anti-CCP and RF curves were observed. Median value for anti-CCP in HIV positive patients was higher than the reference interval, and RF values were, in the reference interval, suggested by the manufacturer. Both anti-CCP and RF are significantly higher in HIV positive patients. ROC analysis showed that anti-CCP distinguishes the two groups better than RF. Because of that, it would be of a great interest to investigate the HIV positive patients after the detailed rheumatological examination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
