Access to antibiotics without prescription in community pharmacies in Yemen during the political conflict.

OBJECTIVES: The practice of dispensing non-prescribed antibiotics aggravates the global burden of antibiotic resistance. The objective of this study is to assess the practice of community pharmacists regarding dispensing antibiotics without a prescription based on simulated clinical scenarios. STUDY DESIGN: Cross-sectional study. METHODS: The study was performed between 15 April to 18 June 2015. Five different clinical scenarios were simulated, involving sore throat, otitis media, cough, diarrhea, and urinary tract infection (UTI). Three different levels of demand were used to convince the pharmacists to dispense antibiotics data was analyzed using SPSS, version 21.0. RESULTS: Two-hundred community pharmacies in Sana'a were visited for each clinical scenario. The majority of pharmacies (73.3%) dispensed antibiotics without medical prescriptions in different levels of demand. Most antibiotics were dispensed for the sore throat simulated scenario (99.5%), followed by cough (92%), diarrhea (75.5%), and otitis media (52%). The lowest percentage of dispensed antibiotics was in the UTI scenario, with 48%. Among the pharmacists who dispensed antibiotics, 74.2% provided an explanation to the simulated patients regarding how to use antibiotics, 77.6% counseled the patient about treatment duration and only 11.9% of the pharmacists asked about the pregnancy status. Regarding the cough scenario, 83% of the pharmacists inquired about the type of cough before dispensing medication. CONCLUSION: Antibiotics in Yemen can be easily obtained without medical prescription or evidence-based indication.

Costs associated with tuberculosis diagnosis and treatment in Yemen for patients and public health services.

This study determined the costs associated with tuberculosis (TB) diagnosis and treatment for the public health services and patients in Sana'a, Yemen. Data were collected prospectively from 320 pulmonary and extrapulmonary TB patients (160 each) who were followed until completion of treatment. Direct medical and nonmedical costs and indirect costs were calculated. The proportionate cost to the patients for pulmonary TB and extrapulmonary TB was 76.1% arid 89.4% respectively of the total for treatment. The mean cost to patients for pulmonary and extrapulmonary TB treatment was US$ 108.4 and US$ 328.0 respectively. The mean cost per patient to the health services for pulmonary and extrapulmonary TB treatment was US$ 34.0 and US$ 38.8 respectively. For pulmonary and extrapulmonary TB, drug treatment represented 59.3% and 77.9% respectively of the total cost to the health services. The greatest proportionate cost to patients for pulmonary TB treatment was time away from work (67.5% of the total cost), and for extrapulmonary TB was laboratory and X-ray costs (55.5%) followed by transportation (28.6%).

Costs associated with tuberculosis diagnosis and treatment in Yemen for patients and public health services

This study determined the costs associated with tuberculosis [TB] diagnosis and treatment for the public health services and patients in Sana'a, Yemen. Data were collected prospectively from 320 pulmonary and extrapulmonary TB patients [160 each] who were followed until completion of treatment. Direct medical and nonmedical costs and indirect costs were calculated. The proportionate cost to the patients for pulmonary TB and extrapulmonary TB was 76.1% and 89.4% respectively of the total for treatment. The mean cost to patients for pulmonary and extrapulmonary TB treatment was US$ 108.4 and US$ 328.0 respectively. The mean cost per patient to the health services for pulmonary and extrapulmonary TB treatment was US$ 34.0 and US$ 38.8 respectively. For pulmonary and extrapulmonary TB, drug treatment represented 59.3% and 77.9% respectively of the total cost to the health services. The greatest proportionate cost to patients for pulmonary TB treatment was time away from work [67.5% of the total cost], and for extrapulmonary TB was laboratory and X-ray costs [55.5%] followed by transportation [28.6%]

The assessment of the antibacterial and antifungal activities of aspirin, EDTA and aspirin-EDTA combination and their effectiveness as antibiofilm agents.

AIMS: To evaluate the antimicrobial activities of aspirin, EDTA and an aspirin-EDTA (A-EDTA) combination against Pseudomonas aeruginosa, Escherichia coli and Candida albicans in planktonic and biofilm cultures. METHODS AND RESULTS: Minimal inhibitory concentrations (MIC) and minimal biocidal concentrations (MBC) were determined using twofold broth microdilution and viable counting methods, respectively. Aspirin's recorded MIC values ranged from 1.2 to 2.7 mg ml(-1). Checkerboard assay demonstrated a synergism in antimicrobial activity upon combination. Aspirin's minimal biofilm eradication concentration values (MBEC) against the established biofilms ranged between 1.35 and 3.83 mg ml(-1). A complete eradication of bacterial biofilms was achieved after a 4-h treatment with the A-EDTA combination. CONCLUSION: Both aspirin and EDTA possess broad-spectrum antimicrobial activity for both planktonic and biofilm cultures. Aspirin used at the MBEC for 24 h was successful in eradicating P. aeruginosa, E. coli and C. albicans biofilms established on abiotic surfaces. Moreover, the exposure to the A-EDTA combination (4 h) effected complete bacterial biofilm eradication. SIGNIFICANCE AND IMPACT OF THE STUDY: There is a continuous need for the discovery of new antimicrobial agents. Aspirin and EDTA are 'nonantibiotic drugs', the combination of which can be used successfully to treat and eradicate biofilms established on abiotic surfaces.
