Show moreOBJECTIVES To identify determinants of carriage of resistant Staphylococcus aureus in both hospitalized patients and individuals from the community in two urban centres in Indonesia. METHODS Staphylococcus aureus cultures and data on recent antibiotic use, demographic, socioeconomic, disease-related and healthcare-related variables were collected from 3995 community dwellers and hospitalized persons. Nasal S. aureus carriage was found in 362 persons (9.1%). Logistic regression analysis was performed to identify which variables were independently associated with carriage of resistant S. aureus. RESULTS The penicillins were the most frequently used antibiotics both in the community and in hospitalized patients. In the community, admission to a hospital was associated with carriage of S. aureus resistant to any of the tested antibiotics [odds ratio (OR) 2.5, 95% confidence interval (95% CI) 1.3-4.9] and any tetracycline resistance (OR 2.4, 95% CI 1.1-5.1). Having no symptoms was associated with less carriage of S. aureus with resistance to any of the tested antibiotics (OR 0.5, 95% CI 0.3-0.9) and any tetracycline resistance (OR 0.5, 95% CI 0.3-0.9). Crowding (OR 4.5, 95% CI 1.2-4.9) and low income (OR 8.9, 95% CI 1.8-43.9) were associated with multidrug resistance. In hospitalized patients, the use of penicillins was associated with resistance to any of the tested antibiotics (OR 3.9, 95% CI 1.4-11.6) and any tetracycline resistance (OR 3.7, 95% CI 1.1-12.0). CONCLUSIONS Antibiotic policies including proper diagnosis, treatment and drug delivery process should be made by healthcare providers in Indonesia to help limit the emergence of antibiotic resistance.

Show moreBackground: To describe the epidemiology and trends of imported malaria in the Netherlands from 2000 through 2007. Methods: Based on national surveillance data regarding all reported infections of imported malaria, diagnosed 2000 through 2007, incidence and trends of imported malaria in the Netherlands were estimated. Travellers statistics were used to estimate incidence, and data on malaria chemoprophylaxis prescriptions were used to estimate the number of unprotected travellers. Results: Importation of malaria to the Netherlands is declining even as more travellers visit malaria-endemic countries. On average, 82% were acquired in sub-Saharan Africa, and 75% were caused by Plasmodium falciparum. The overall incidence in imported falciparum malaria fell from 21.5 to 6.6/10,000 of unprotected travellers. The percentage of unprotected travellers rose from 47% to 52% of all travellers. The incidence of imported falciparum infections is greatest from Middle and West Africa, and decreased from 121.3 to 36.5/10,000 travellers. The import of malaria from this region by immigrants visiting friends and relatives (VFR) decreased from 138 infections in 2000, to 69 infections in 2007. Conclusion: The annual number of imported malaria shows a continuing declining trend, even with an increasing number of travellers visiting malaria endemic countries. VFR import less malaria than previously, and contribute largely to the declining incidence seen. The decline is not readily explained by increased use of chemoprophylaxis and may reflect a reduced risk of infection due to decreasing local malaria transmission as observed in some malaria endemic areas. Nevertheless, the increasing number of unprotected travellers remains worrisome. Show less
