There are about 297 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.
Concomitant administration of multiple vaccines, including live attenuated immunizations, is safe and effective. Some restrictions apply for live vaccines; administering a live-virus vaccine within 4 weeks after administration of another live-virus vaccine can decrease immunogenicity to the second administered vaccine. Thus, it is recommended that live-virus vaccines should be administered the same day or ≥4 weeks apart. Data on co-administration of the currently available whole-cell killed Oral Cholera Vaccine (OCVs) with other oral vaccines, specifically, oral polio vaccines (OPV) is lacking. Although the risk of immunological interference due to co-administration of live vaccines with non-live vaccines is considered small if at all, a theoretical concern of interference has been raised. Given the substantial geographic correlation between polio- and cholera-affected and at-risk areas, which include some of the world's most impoverished and hard-to-reach populations, a strategy of co-administration of OCV with OPV to children targeted to receive OPVs has the potential to optimize the use of limited resources and improve coverage for both vaccines. The manufacturer recommendation for a two-week interval between administration of OPV and OCV precludes an integrated campaign or routine use in which OCV could be co-administered with OPV.
Dietary fiber, a non-digestible carbohydrate, used in decades for the beneficial effect on health with physiological importance because such compounds have low energy values. These indigestible carbohydrates generally reach the large intestine undigested and unabsorbed, they are often used in many functional and/or low-calorie food and beverages. Researchers have stated that dietary fiber especially digestive-resistant maltodextrin has innumerable beneficial effects on human health, such as improving intestinal regularity by increasing fecal bulk, stimulating peristalsis and shortening gastrointestinal transit time. Resistant maltodextrin (Fibersol-2) is a low viscosity, water-soluble, indigestible dextrin produced by the treatment of corn starch with acid, enzymes, and heat. Dietary fiber, a non-digestible carbohydrate, has been used in decades for the beneficial effect of health with physiological importance. In developing countries most of the diarrhea episodes occur during the first two years of life and till date antibiotics have been found to have no role in over seventy five percent of young childhood diarrhea. Toddler's diarrhea which affects children aged 6 to 60 months is known as chronic nonspecific diarrhea of childhood. The stool is frequently watery or loose and may have food particles in it. Despite the diarrhea, the child continues to grow and gain weight, remains active and has a normal appetite. The beneficial effects of resistant maltodextrin are well known in developed countries; however, data are lacking in developing countries. It has become imperative to know its safety, tolerability and acceptability in small children with or without diarrhea in developing countries such as in Bangladesh.
Overactive bladder (OAB) is a chronic symptom complex that can substantially impair quality of life. Pharmacological management using antimuscarinics agent remain the mainstay of therapy and effectively reduce OAB symptoms. However, despite the proven efficacy of such agents, their tolerability may be limited by adverse events, mostly dry mouth. In fact these adverse events often lead to poor compliance and discontinuation of therapy.The β3-adrenoceptor agonist, mirabegron, which acts via a different mechanism of action to antimuscarinics, could potentially improve the efficacy/ tolerability balance over current standard of care in the management of OAB.β3-adrenoceptor agonists relax detrusor smooth muscle during the bladder storage phase and increase bladder capacity without negatively affecting voiding parameters. Different study has report efficacy and safety of mirabegron but not done in our country. Investigators will evaluate the efficacy and safety of mirabegron comparison with solifenacin succinate in the treatment of overactive bladder.This is a hospital based prospective randomized controlled clinical trial will be conducted from July 2016 to November 2017 in the department of urology, Bangabandhu Sheikh Mujib Medical University (BSMMU). Among the patient with overactive bladder who will visit to Urology outpatient department (OPD) of BSSMU, 56 patient who will fulfil the inclusion criteria will be selected. Selected patients will be evaluated by history, physical examinations and investigation like routine urine analysis & culture, serum creatinine, random blood sugar, X-ray kidney, ureter & bladder (KUB) region,ultrasonogram (USG) of KUB region with maximum cystometric capacity (MCC) & post-viodal residue (PVR). After taking informed consent, selected 82 patient will be randomly divided in to experimental group and control group, each containing 41 patients. All patients will be entered into one week run-in period, when they will instructed to stop any drug including any anti-cholinergics, if they are getting it before. Patient will be supplied with a Bengali version micturition diary from and instructed to complete a 3 day voiding diary. Average of three day will be calculated for 24 hours.Overactive symptom score will be calculated by interviewing the patient for urinary symptom for last 7 days. Experimental group will receive Mirabegron 25mg and control group will receive solifenacin succinate 5 mg all are at night for 12 weeks. Patients in both group will be regularly followed up 12 weeks at 4 weeks interval.Patient will be supplied with a Bengali version micturition diary from and instructed to complete a 3 day voiding diary in each follow up schedule visit at the end of 4, 8 and 12 weeks. Overactive symptom score will be calculated by interviewing the patient for urinary symptom for last 7 days in each visit.Patient will be evaluated for any adverse effects during the medication. Data will be collected, complied, computed and appropriate statistical analysis will be done as per objectives
This is a trial to evaluate the safety and immunogenicity of double mutant heat-labile toxin LTR192G/L211A (dmLT) from Enterotoxigenic Escherichia coli (ETEC) by oral, sublingual, or intradermal vaccination in approximately 135 healthy adult volunteers, age 18-45 years. Study duration is approximately 2.5 years, with each participant duration for up to 9 months depending on the route of dmLT administered. There is no specific hypothesis being tested in this study. The primary objective of this study is to assess the reactogenicity, safety, and tolerability of dmLT when administered in three sequential doses, over a range of dosages by oral, sublingual, or intradermal routes.
Vitamin D deficiency in childhood leads to poor bone growth and muscle weakness, yet it is unknown if the amount of vitamin D a woman consumes during her pregnancy affects her child's bone and muscle development. In collaboration with researchers in Bangladesh, the investigators recently completed a study of vitamin D supplementation during pregnancy in which women were assigned to 1 of 5 groups containing vitamin D or placebo (no vitamin D). The investigators now aim to conduct a follow-up study of a sample of 250 3-4 year old children born to these mothers to test the possible effects of vitamin D supplementation in pregnancy on children's bones, their body composition and the strength of their muscles.
Treatment failure of Spondyloarthropathies (SpA) leads to marked functional disability, higher rates of morbidity, mortality and poor quality of life. In TB endemic countries effective and safe drugs are to be in hand to manage this group of patients. The aim of this study will be to evaluation the risk of tuberculosis and other infections in refractory SpA patients treated with tofacitinib. After having consent 174 adults will be enrolled. Follow up period will be 9 months (visits 0, 1, 3, 6 and 9). Study subjects (87) will receive tofacitinib (5 mg 12 hourly). Control patients will get etanercept (50 mg subcutaneously every 7 days interval for 1st month then 50 mg in 15 days interval for 2nd month then 50 mg every 21 days interval till final visit. Treatment efficacy assessment tool will be BASDAI, ASDAS-ESR, ASDAS-CRP and ASQoL for quality of life. Occurrences of tuberculosis and serious infection will be the primary end point of this study. The quantitative variables like ESR, CRP, BASDAI, ASDAS-ESR, ASDAS-CRP and ASQoL scores will be computed as mean and SD. Occurrences of TB and infection will be expressed in number and percentage. In between groups according to data distribution, students't test or ManWhitny U test will be done. The P value <0.05 will be considered significant. Each patient will enjoy every right to participate or refuse or even withdraw from the study at any point of time. Anonymity and data confidentiality will be maintained strictly. Ethical clearance will be obtained from Institutional Review Board (IRB) of BSMMU. The expected utility of this study will be; a) reporting on occurrence of TB and other infections in SpA patients with tofacitinib and etanercept, b) if identified safe and effective physician can use the agents without fear, c) for dose spacing of etanercept the cumulative dose will be low might make the drug affordable and also reduce the risk of TB and other infections, d) for spaced follow up schedule there will be minimized physician visit, lab testing etc.
Hepatocellular Carcinoma (HCC) is the fifth most common cancer world-wide. It is particularly prevalent in Asia, and its occurrence is highest in areas where hepatitis B is prevalent, indicating a possible causal relationship. Follow up of high-risk populations such as chronic hepatitis patients and early diagnosis of transitions from chronic hepatitis to HCC would improve cure rates. In most cases HCC is detected late resulting in increased mortality and morbidity. The purpose of this study is to develop and test non-invasive biomarkers based on methylation changes in PBMC, T-cells and circulated tumor DNA in hepatocellular carcinomas patients.
This is a randomized, double-blind, community-based efficacy trial of different doses, forms, and frequencies of zinc supplementation for the prevention of diarrhea and promotion of linear growth among children 9-11 months of age in Dhaka, Bangladesh.
INTRODUCTION In 2014, 50 million children under 5 suffered from acute malnutrition, of which 16 million suffered from SAM, most of them living in sub-Saharan Africa and Southeast Asia. SAM children have higher risk of mortality (relative risk between 5 and 20). It is an underlying factor in over 50% of the 10 - 11 million preventable deaths per year among children under five. At present, 65 countries have implemented WHO recommendations for SAM treatment (both in-patient for complicated cases and outpatient for uncomplicated cases) but these programs have very low coverage, reaching only around 10 - 15 % of SAM children. In 2009 the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) issued a joint statement in an effort to harmonize the application of anthropometric criteria for SAM diagnosis and monitoring in child aged 6 - 59 months; the statement presents recommended cut-offs, and summarizes the rational for the adoption, of the following two anthropometric criteria: 1. Weight-for-Height Z-Score (WHZ): "WHO and UNICEF recommend the use of a cut-off for weight-for-height of below -3 standard deviations (SD) of the WHO standards to identify infants and children as having SAM." Additionally, analysis of existing data show that children with a WHZ < -3 have a highly elevated risk of death. 2. Mid-Upper Arm Circumference (MUAC): "WHO standards for the MUAC-for-age show that in a well-nourished population there are very few children aged 6 - 59 months with a MUAC less than 115 mm. Children with a MUAC less than 115 mm have a highly elevated risk of death compared to those who are above. Thus it is recommended to [use] the cut-off point [of] 115 mm to define SAM with MUAC." GENERAL OBJECTIVE To generate new evidence on pathophysiological process, nutritional needs and risks associated with different types of anthropometric deficits in children under 5, in order to optimize the diagnosis and treatment of SAM. SPECIFIC OBJECTIVES - To compare nutritional status, metabolism, pathophysiological process and risks in different types of SAM anthropometric diagnosis, with or without concomitant stunting (growth retardation). - To analyze the extent to which current SAM treatment is promoting recovery and healthy growth in different categories of children. - To evaluate the relevance of current discharge criteria used in nutrition programs and their association with metabolic recovery, in different age groups and among those who are stunted. - To test novel rapid tests of emerging biomarkers predicting long-term outcomes and mortality risk in the field. METHODOLOGY A wide range of supplementary information related to nutritional status, body composition, metabolic and immune status, including emerging biomarkers of metabolic deprivation and vulnerability, will be collected besides anthropometry during prospective observational studies. They will be collected with minimum level of invasiveness, compatible with field work requirements in the humanitarian context. Phase 1: Cross-sectional surveys. Phase 2: Prospective cohort studies involving SAM children between 6 months and 5 years old. Children admitted as SAM at the nutrition centers will be enrolled into the cohort. The follow up duration will be at least three months. EXPECTED OUTCOMES - Confirmation of current hypotheses related to: 1. possible misdiagnosis of SAM made by MUAC or WHZ criteria, 2. varying degree of severity and need for admission to treatment of the different types of diagnosis, 3. underlying heterogeneity of the pathophysiology. - Generation of new algorithms for the assessment and classification of malnourished children, based on the combined use of emerging biomarkers and anthropometric measures, or on the modification of anthropometric criteria. - Generation of new treatment paradigms based on the predictive value of biomarkers in combination with traditional anthropometric measures. This will enable us to assess the power of current treatment regimens to promote long-term weight gain and growth and will allow us to tailor treatment to the physiological needs of the child.
It has been observed that despite administration of apparently adequate thyroid hormone replacement in hypothyroid patients, many of them experience persistent fatigue and fatigue-related symptoms. Carnitine transports long chain fatty acids into the mitochondria whereupon the high energy source (ATP) becomes synthesized. Levocarnitine administration reduced fatigue related symptoms in hypothyroid patients receiving thyroid hormone replacement. The present study deals with alleviation of fatigue in hypothyroid patients by carnitine supplementation.
