There are about 620 clinical studies being (or have been) conducted in Bangladesh. 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.
This randomized clinical trial will assess the immune response in infants following administration of three types of oral poliovirus vaccine trivalent OPV (tOPV), monovalent OPV type 1 (mOPV1), bivalent OPV types 1 and 3 (bOPV) using two different schedules: a short schedule with administration at two week intervals and the usual schedule at four week intervals. The results of this study will guide the Global Polio Eradication Program in the implementation of new strategies that may: 1) improve the quality of the response to outbreaks following importation of wild poliovirus type 1 by shortening the interval at which several OPV doses are provided; 2) prevent alternate outbreaks of type 1 and type 3 poliovirus by using bOPV in outbreak responses in countries with weak routine immunization systems; and 3) prevent the emergence of type 2 vaccine-derived poliovirus through the replacement of tOPV with bOPV in immunization campaigns and routine immunization programs.
In this Phase II randomized controlled clinical trial, generally healthy male and female children from 24 through 59 months of age will be enrolled in Kamalapur (Dhaka), Bangladesh. The study is expected to continue for at least 6 months following vaccination. The experimental intervention is Serum Institute of India Ltd's Trivalent, Seasonal Live Attenuated Influenza Vaccine (SIIL LAIV). The study vaccine has been formulated according to WHO recommendations for the 2011-2012 Northern Hemisphere influenza season. The SIIL LAIV is administered in a 0.5 ml intranasal dose (one spray of 0.25 ml per nostril) via a reusable sprayer device and a single-use nozzle that produces a fine mist that is primarily deposited in the nose and nasopharynx. The comparator vaccine will be an inactive placebo identical in appearance to the active vaccine. The primary study hypothesis is that LAIV is safe and well tolerated by children aged 24 through 59 months in Bangladesh. A secondary hypothesis is that LAIV is immunogenic among children receiving study vaccine as compared to children receiving placebo.
- The present study was undertaken to assess the efficacy and safety of two different insulin sensitizers (namely Pioglitazone and Metformin) among subjects with type 2 diabetes mellitus (T2DM) in Bangladesh. - A prospective, double-blind, single group, 'within-subject' designed clinical trial of 77 diagnosed T2DM patients out of 130 patients with glycosylated haemoglobin (HbA1c) ≥7.2±1.5%, aged 46±6.4 years and registered for diabetes treatment in Bangladesh Institute of Research and Rehabilitation in Diabetes Endocrine and Metabolic Disorders (BIRDEM) was carried out. - The study was conducted between November 2008 and September 2010. - Baseline data, included case history of the patients,anthropometric measurement, biomedical parameters psychosocial factors, were collected from each subject and then enrolled to receive treatment with 001 drug once daily for three months, then the patients were left for wash out with metformin 850mg once daily for one month; then they received 002 drug once daily for further three months. - Dietary chart was remained as before. - DNA was isolated by Chelex method using the primers and control DNA,restriction Digestion Enzyme Endonuclease Hae 111 for genotyping PPARγ-(Peroxisome Proliferator Activated Receptor gamma)Pro12Pro - (Proline12Proline)/Pro12Ala-(Proline12 Alanine))/Ala12Ala-(Alanine12Alanine). - The blinded drugs were decoded after analyzing results, 001 tablet was pioglitazone (30 mg once daily) and 002 tablets was metformin (850mg once daily). Bio-medical outcomes were measured to assess the efficacy of both the drugs each month. After finishing the treatment period the effects of two drugs were compared using SPSS.And the association between the pioglitazone drug effects and genetic polymorphism was also assessed. - The metformin effects was assessed also using the response rate of HbA1c <7.0% after 3 months treatment to the patients.
Vitamin A supplementation at birth may increase survival of infants through one year of age by reducing mortality from infectious diseases, though current studies are not conclusive on this point. The goal of our study is to determine if supplementation of newborn infants with 50,000 IU of vitamin A improves aspects of immune function that may be impaired by vitamin A deficiency. Our underlying assumption is that supplementation may thus decrease risk of death by improving immune function and the ability to survive infections. This project will be limited to the examination of the impact of vitamin A on immune function and will not aim to determine the impact on morbidity or mortality, which would require larger sample sizes. The hypotheses addressed by this study are as follows: Provision of vitamin A supplements to newborns at risk of vitamin A deficiency will (1) improve functioning of the thymus (the source of T lymphocytes, cells of the immune system that are important in response to infection and immunization); (2) enhance T lymphocyte-mediated responses to standard vaccines given at birth and early in infancy; and (3) improve gut barrier function (i.e., ability to prevent bacterial infection across the epithelial barrier), relative to provision of a placebo.
Vitamin D exerts its effects via the Vitamin D Receptor (VDR) present in activated macrophages and induces expression and release of the cathelicidin, LL-37, a human antimicrobial peptide involved in killing of MTB. We aimed to investigate whether treatment of newly diagnosed pulmonary TB patients for 2 months with adjunctive PBA and vitamin D (Cholecalciferol) in combination with standard DOTS therapy (i) can improve response to standard short course TB therapy towards a rapid recovery; (ii) can induce expression of LL-37 in macrophages; (iii) can enhance killing capacity of macrophages isolated from TB patients infected in vitro with MTB; and (iv) does not evoke any adverse effects.
Hypothesis: The immunogenicity of oral polio vaccine (OPV) will be enhanced in Bangladeshi infants who receive bicarbonate buffer at the time of polio immunization.
The primary aim of this study is to determine the impact of community-based screening and treatment of abnormal vaginal flora and urinary tract infections in early pregnancy (13-19 weeks) on preterm live birth in Sylhet district, Bangladesh. Hypothesis 1: Community-based screening and treatment of abnormal vaginal flora (Nugent score >4) and urinary tract infections in early pregnancy (13-19 weeks) will reduce the population rate of preterm live birth by at least 15%. The secondary aims of this study are: - To determine the impact of community-based screening and treatment of abnormal vaginal flora and urinary tract infections on the: - proportion of pregnancies with outcomes occurring prior to 37 weeks (late miscarriage, preterm still birth and preterm live birth); and - proportion of babies with early onset neonatal sepsis. - To determine the prevalence of abnormal vaginal flora and urinary tract infections, including asymptomatic bactiuria, among pregnant women in Sylhet district, Bangladesh. - To evaluate the accuracy of simple, low-cost, point of care diagnostic tests for detecting bacterial vaginosis and urinary tract infections by community health workers in a rural, developing country setting.
The proposed study is a four-arm double-blind randomized controlled single center trial to evaluate, by examining post-vaccination seroprotection titers, the lot-to-lot consistency of three lots of Japanese Encephalitis live attenuated SA 14-14-2 vaccine (LJEVac) manufactured in a new good manufacture practice (GMP) facility, and to establish non-inferiority of the new vaccine in comparison to a single lot of the same vaccine manufactured in the existing facility. The study aimed to enroll a total of 1,000 Bangladeshi infants aged 10 to 12 months. In addition to providing immunogenicity data, this study provided local safety data of JE live attenuated SA 14-14-2 vaccine among Bangladeshi children. This is the first step to secure licensure for this life-saving vaccine in Bangladesh as well as provide data to support WHO prequalification of JE live attenuated SA 14-14-2 vaccine.
The purpose of this study is to test the impact on child growth of three specially formulated complementary food supplements vs. Plumpy'Doz, a previously tested, commercially available complementary food, and vs. a control group that receives no food. All groups will receive nutrition education related to infant and young child feeding. This will be a cluster-randomised trial in children 6-18 months old in rural Rangpur and Gaibandha in Bangladesh.
Hypothesis: During rehabilitation phase of management of severe acute malnourished Bangladeshi infants less than 6 months old, rates of weight gain will be significantly more in children fed F-100 and diluted F-100 compared to those fed infant formula. Brief summary: Until recently, severe malnutrition has been relatively rare in infants younger than 6 months, but with urbanization and the HIV/AIDS pandemic it is feared that the incidence of severe malnutrition among young infants will rise. The question of how best to feed infants aged <6 months has thus come to the forefront. Given the lack of published evidence regarding the most advantageous formulations for feeding severely malnourished infants aged <6 months, there is a need for observational studies and comparative randomized trials of alternative formulations to guide decisions about optimum dietary management in this age group. This area has been aptly considered a research priority during the consultation meeting of experts from all over the world convened by the World Health Organization on management of severe malnutrition in September 2004. In the WHO case-management guidelines for severe malnutrition, there is no separate provision for young infants (infants less than 6 months old). The guidelines suggest the use of a low-solute formula (F-75) and continued breastfeeding in the initial stabilisation phase. In the rehabilitation phase, the guidelines advise F-100 with an energy density of 100kcal/100ml to promote catch-up growth. There is a concern that the renal solute load from using F-100 is too high for young infants, and some groups have started using diluted F-100 with an energy density of 75 kcal/100 ml. Another related issue is the contribution of breastfeeding in dietary intakes during rehabilitation. In severely malnourished infants, breast milk intakes are likely to be low initially when appetite is poor, but may be substantial as the infant recovers. Uncertainty about breast milk intakes has led to conflicting opinions and advice, weaning from the breast as it is not providing sufficient energy (1). The aim of this study, to be conducted in a carefully supervised Nutrition Rehabilitation Unit (NRU), will compare three recovery diets (Infant formula, F-100 and diluted F-100) in order to provide the evidence-base to determine if a change or add-on in terms of diet in the WHO guidelines is needed. It will also measure the potential renal solute load (mosmol/l), serum electrolytes and plasma osmolality of the same children. Body composition of the infants will also be measured using stable isotope dilution technique before and after the intervention diet is provided.
