Purpose: To evaluate the association between patient's knowledge of Hepatitis-B and Health Related Quality of Life (HRQoL). Methods: A cross sectional, descriptive study was undertaken with 390 hepatitis-B patients attending two public hospitals in Quetta City, Pakistan. Knowledge of hepatitis-B was assessed using a pre-validated questionnaire. European Quality of Life scale was used for the assessment of HRQoL. Descriptive analysis was used to elaborate patients' demographic characteristics while inferential statistics were applied to report the association among study variables. Spearman's rho correlation was used to identify the association between variables. Results: Out of 390, (230, 59.5 %) were males and the mean age of the subjects was 36.2 ± 9.2 years. One hundred and three (26 %) had primary level of education and 109 (27.9 %) were employees in the private sector. Eighty four (21 %) had a monthly income of between 10001-15000 Pakistan rupees (1 PKR = 0.0115527 USD) with 272 (69.7 %) respondents resident in urban areas. Mean HRQoL and Hepatitis-B related knowledge (HBRK) scores were categorized as poor (0.37± 0.3) and (8.52 ± 2.7) respectively. The correlation coefficient between HRQoL and HBRK was -0.102 (p < 0.001), indicating a week negative association between the study variables. Conclusion: The findings indicate a negative association between Hepatitis-B related knowledge and HRQoL. Therefore, providing disease-related knowledge to patients does not necessarily improve HRQoL. More attention should be given to identify individual factors that affect HRQoL among patients with Hepatitis-B. [ABSTRACT FROM AUTHOR]

Purpose: To explore medical practitioners' perceptions towards irrational malaria treatment practices in Pakistan. Methods: A qualitative study was designed to explore the perceptions of medical practitioners regarding antimalarial prescribing practices in two major cities of Pakistan, namely, Islamabad (national capital) and its twin city, Rawalpindi. Semi-structured interviews were conducted using in-depth interview guides to collect data. Nineteen interviews with doctors working at different public and private hospitals in Islamabad and Rawalpindi were conducted at a place and time convenient for the respondents. The interviews were audio-taped, transcribed verbatim, and evaluated by thematic content analysis and other author analysis. Results: The interviews focused on three major components, i.e., treatment practices in malaria and influencing factors, role of Malaria Control Program, and suggestions for improvements. Thematic content analysis of these components yielded further themes: (1) Prevalence of malaria, (2) Common trends of treatment, (3) Current scenario of rational drug use, (4) Major contributing factors to irrational drug use, (5) Use of antibiotics, (6) Role of healthcare system, (7) Role of Malaria Control Program, (8) Role of hospital pharmacist, (9) Collaborative efforts of doctors and pharmacists in promoting rational treatment practices, and (10) Strategies to improve current treatment practices. Conclusion: The current study showed that all the respondents in the two cities agreed that irrational prescribing practices, unavailability of drugs, lack of awareness and adherence of prescribers to standard treatment guidelines, are the major factors contributing to irrational drug use in malaria in Pakistan.

Contact tracing is the most commonly employed process of identifying the relevant contacts of a person with an infectious disease. A systematic review and meta-analysis on contact tracing of tuberculosis (TB) suspects has shown that the yield of household contact investigation in low- and middle-income countries was 6.5 %. However, a recent study from Malaysia has shown the yield of TB contact tracing as low as 0.49 %. Engaging community pharmacists and alternative practitioners in tracing TB suspects in Malaysia is context-specific and can significantly decrease transmission and incidence of the disease.

Purpose: Disease state may contribute to alteration in drug pharmacokinetics. The purpose of this study was to determine the effect of non-insulin dependent diabetes mellitus (NIDDM) on the pharmacokinetics of glipizide. Methods: An open, single-dose, parallel design was applied to the study. Glipizide tablet (5 mg) was administered to healthy and diabetic human volunteers after over-night fast. Blood samples were collected, centrifuged and the plasma assayed using a sensitive and validated reverse phase high performance liquid chromatography (RP-HPLC) method. Various pharmacokinetic parameters were computed from the data obtained. Results: The AUC0-∞ values for healthy and diabetic volunteers was 1878 ± 195 and 1723 ± 138 ng.h/ml, respectively; these values were not significantly different (p > 0.05). The t1/2 for healthy volunteers was 3.04 ± 0.27 h while that for diabetic subjects was 2.98 ± 0.16 h. Clearance for healthy and diabetic volunteers was 0.59±0.06 and 0.64±0.05 ml/min/kg, respectively. These and other pharmacokinetic parameters assessed were not significantly different between healthy and diabetic volunteers (p > 0.05). Conclusion: Although glipizide showed slightly more rapid clearance from the body of diabetic volunteers than from healthy volunteers, this difference, like those for other pharmacokinetic parameters, was not significant (p > 0.05).
