There are about 3285 clinical studies being (or have been) conducted in Pakistan. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Studies have established that high blood pressure (BP) is the most common risk factor for cardiovascular disease (CVD). Despite a heavy burden of hypertension (33% of all persons aged 45 years and over), there are no reliable data on comparative strategies to manage hypertension in Pakistan. Our Wellcome Trust funded pilot study in Karachi, Pakistan on 320 adults aged 40 years and over showed that the prevalence of hypertension (95% CI) was 40.3% (34.9-45.7%), and CVD was 32.5% (27.6-37.8%). We will now conduct a study with two components: 1) cross sectional study to determine the prevalence of CVD, and its determinants in Karachi, Pakistan; and 2) prospective, 2x2 factorial design, cluster allocation intervention study to evaluate the impact of a i) Population approach of household health education (HHE) by community health workers (CHW) on BP levels of population aged 5 years or over in low-middle income communities of Karachi; and ii) High-Risk approach of special BP management administered by intensively trained local general practitioners on BP levels of hypertensive subjects aged > = 40 years from the above population. The cost effective BP control strategy would serve as a model for a much-needed national level hypertension control programme in Pakistan, and possibly other developing countries in South Asia. We hypothesize that 1) HHE delivered by trained CHW is superior to no HHE in lowering BP levels of the population; and 2) management of hypertension by specially trained GPs is better than usual care provided in the communities of Karachi in lowering blood pressure of hypertensive subjects.
Approximately one-third of neonatal deaths in developing countries are due to infections acquired through the birth canal and/or exposure to an unclean environment soon after birth. Current World Health Organization recommendations for the management of infants younger than 2 months of age who have serious bacterial infections involve hospitalization and parenteral therapy for at least 10 days with antibiotic regimens containing penicillin or ampicillin combined with an aminoglycoside.However, in many settings throughout the developing world, this is not currently possible, nor is this standard of care likely to be feasible in the near future. Several studies have reported that for a variety of sociocultural reasons many families are unable or unwilling to access hospital-based care and their sick young infants do not get hospitalized, and instead, receive a variety of home-based antibiotic therapies, or none at all. In our community field sites, approximately 70% of families refuse hospital referral for a sick newborn, despite provision of transport. Thus, there is an urgent need to define the role of community/first-level facility-based care versus hospitalization for the management of young infants with serious bacterial infections, and the potential for community-based parenteral antibiotics as an alternative strategy in resource poor areas with high neonatal mortality rates. Bang and colleagues have demonstrated significant reductions in neonatal mortality from infections in an underdeveloped rural district in Maharashtra, India by a field-based case management approach which used oral cotrimoxazole and intramuscular gentamicin given for 7 days as treatment for neonates with sepsis. This study is an equivalence randomized controlled trial (RCT) comparing once daily IM ceftriaxone injection to once daily IM procaine penicillin and gentamicin injection, to once daily intramuscular gentamicin injection and twice daily oral cotrimoxazole, given for 7 days in babies with clinically-diagnosed possible serious bacterial infection (pneumonia, or sepsis with or without local infections such as skin or umbilical infections) whose families refused referral to a hospital. After supplementary informed consent, patients meeting specific inclusion and exclusion criteria are randomly allocated to one of the three regimens being tested. The study hypothesis is that all 3 regimens will perform equally well in the treatment of sepsis in a first-level facility setting.
