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.
The purpose of this study is to assess the incidence and associated healthcare utilization of RSV-associated, suspected LRTI in a general population of infants from birth up to 2 years of age, and also to assess the accuracy of a newly developed LRTI case definition and severity scale compared to two existing definitions. The study will also assess the population attributable risk percent of RSV LRTI on the development of wheeze and asthma from 0 to 6 years of age.
We hypothesize that PKDL develop after SSG as well as after Miltefosine mono-therapy for VL; anti-inflammatory cytokines such as IL-10, TGF-β, serum lipids play key role for its pathogenesis & PKDL patients are genetically predisposed; diagnostic tool based on immunofluorescence technique will be more sensitive than slit skin examination for diagnosis of PKDL.
Background (brief): 1. Burden: Neonatal death still unacceptably high in low income countries. The common causes of neonatal death are pneumonia, sepsis and omphalitis. Many neonatal infections occur because the mother's hands or the hands of the person who attended the birth are unclean. Our previous study found that there was substantial concern about excessive exposure of the mother or the neonate to water during handwashing because of the perception that frequent contact with water could lead to respiratory illness. 2. Knowledge gap: Chlorhexidine has been evaluated for use in hand hygiene applications in high-income countries, particularly in healthcare, but it has not been evaluated or promoted for hand cleansing at the household level in low- and middle-income countries. 3. Relevance: A waterless hand cleanser employing chlorhexidine would overcome important barriers to handwashing with soap, perceptions of cold resulting from exposure to water, and the time limitations perceived by mothers. Hypothesis: Mothers who are exposed to a chlorhexidine-based hand cleansing intervention will clean their hands (with chlorhexidine or soap and water) more frequently than mothers who are not exposed to the chlorhexidine-based hand cleansing program. Objectives: The primary objective 1. To demonstrate the behavioural impact of chlorhexidine-based hand hygiene intervention on hand cleansing of mothers during the neonatal period The secondary objectives 2. To demonstrate the impact of chlorhexidine-based hand hygiene intervention on hand cleansing of other family members, visitors to the neonate, and birth attendants during the neonatal period 3. To evaluate the acceptability of chlorhexidine for hand cleansing in the neonatal period among mothers, other family members, and birth attendants Methods: We propose a randomized controlled trial in a rural area of Bangladesh, with an active control. Randomization will be at the level of the participating pregnant woman. Each arm will include 150 participants. All intervention visits will follow baseline data collection. A trained health and hygiene promoter will carry out two visits in the antenatal period and one postnatal visit to deliver intervention messages. Outcome measures: 1. Observed hand cleansing behavior of mother with chlorhexidine or soap and water at critical times. 2. Observed hand cleansing behavior of other household members and visitors to home with chlorhexidine or soap and water at critical times.
Optimal fluid therapy in severe falciparum malaria has not been well defined, especially in resource poor settings where access to mechanical ventilation is limited. Recent studies suggest that liberal fluid resuscitation is harmful for severe malaria patients despite they often being hypovolemic on admission. In order to elucidate the minimum fluid therapy required to prevent complications in severe malaria, we will conduct a prospective observational study in adults with severe malaria, and also in adults with severe sepsis as a comparison group. The objective of this study is to describe the association between hemodynamic variations in conventional fluid management and the probability of developing acute kidney injury (AKI) or pulmonary edema in adults with severe malaria and severe sepsis. Hemodynamic measurements will be obtained by using transpulmonary thermodilution and arterial pulse contour analysis.
The primary aims of this study are: 1) to determine whether maternal prenatal vitamin D3 supplementation (4200 IU/week, 16,800 IU/week, or 28,000 IU/week) versus placebo increases or decreases infant length at 1 year of age, and 2) to determine whether maternal postpartum vitamin D3 supplementation (28,000 IU/week) versus placebo increases or decreases length at 1 year of age among infants born to women who received vitamin D 28,000 U/week during pregnancy. Infants enrolled in the study will be followed for 2 years to document the persistence of any observed effects measured at 1 year of age. This study aims to enroll 1300 pregnant women in the 2nd trimester at a maternity hospital in Dhaka. Participants will be randomized to one of three doses of vitamin D3 (4200 IU/week, 16,800 IU/week, or 28,000 IU/week) or placebo throughout pregnancy. Women in the 28,000 IU/week group will be additionally randomized to either placebo or a continuation of 28,000 IU/week for 6 months postpartum. In addition to linear length, the trial will include analyses of inflammatory and hormonal determinants of infant growth, epigenetic phenomena that affect vitamin D metabolism, and diarrheal and respiratory morbidity in the infants.
Here the investigators propose to preliminarily investigate the safety and effects of probiotics in infants in Bangladesh through a pilot randomized clinical trial. The investigators hypothesize that two probiotics are safe for infants in Bangladesh and may have an effect on biomarkers of gut health and immunity. The specific aims of this pilot are: i) to confirm the safety of administering probiotic strains to infants in low-income countries, ii) to determine the effects of dosing frequency on colonization and persistence of probiotics in the GI tract, iii) to measure markers of intestinal and immune function and microbiota structure.
Around 0.5 million under-five children are currently suffering from severe acute malnutrition (SAM) in Bangladesh and are at risk of death. Children with SAM and complications should be treated in a health care facility. It is imperative, however, to manage children with SAM but without any complications in the community. This requires a ready-to-use-therapeutic food (RUTF) that conforms to standard recommendations on its composition. The prototype RUTF is peanut based, made outside Bangladesh, and has to be imported. By developing a RUTF using local food ingredients, test it for acceptability and efficacy in the treatment of children with SAM, hopefully make the treatment of SAM cost-effective and sustainable. Hypothesis: Does the locally developed ready-to-use-therapeutic foods (RUTFs) demonstrate similar or better acceptability and efficacy in the treatment of children suffering from severe acute malnutrition (SAM) when compared to the prototype RUTF (Plumpynut)?
This study is conducted in Asia. The aim of this non-interventional study is to evaluate the the current status of diabetes management, control, and complications in diabetic subjects with type 2 diabetes in Bangladesh.
The present study is intended to evaluate the safety and tolerability of topical OC-10X Ophthalmic Suspension in healthy human subjects. OcuCure Therapeutics, Inc. (Roanoke, VA) has developed a lead compound, known as OC-10X, which is a selective tubulin inhibitor under development for the treatment of Proliferative Diabetic Retinopathy (PDR) and Age-related Macular Degeneration (AMD). When administered as a topical eye drop, OC-10X has demonstrated both anti-angiogenic (inhibition) and angiolytic (regression) properties in animal models of AMD. Unlike other therapies, OC-10X provides the efficacy of a vascular targeting agent without the traditional toxicity and works downstream independently of growth factors. As demonstrated by OcuCure's preclinical data, tubulin inhibition using OC-10X has promise as a new therapeutic approach. PDR is a major cause of blindness in adults and is also caused by the growth of abnormal blood vessels. These new blood vessels are fragile and may hemorrhage into the vitreous. PDR affects up to 80% of all diabetics who have had diabetes for 15 years or more. If administration of OC-10X is well tolerated as a topical eye drop and is well tolerated systemically, then OC-10X will have the potential to provide benefits to patients with ocular diseases associated with angiogenesis.
Rotavirus is the leading cause of severe gastroenteritis in infants and young children worldwide and is estimated to account for 600,000 deaths in children <5 years of age. However, live oral enteric vaccines (e.g. OPV, cholera vaccines, typhoid vaccine) have been less immunogenic in poor communities with high levels of malnutrition and poor sanitation. Rotavirus vaccines also appear to be less immunogenic in the setting where they are most needed. High maternal antibody (IgG) to rotavirus and breast feeding near the time of vaccination may inhibit rotavirus vaccine effectiveness. We propose a quick study to look at practical ways to improve the immunogenicity of rotavirus vaccine in our own setting in Bangladesh. The objectives are to assess if delaying Rotarix vaccination will improve the immune response to the vaccine and to assess if avoiding breastfeeding in the 45 minutes before and after vaccine administration will improve the immune response to administration of Rotarix vaccine. The study will be conducted in the urban Dhaka Mirpur Community, a setting where previous rotavirus vaccine immunogenicity studies have been successfully conducted. A total of 300 infant will be randomly assigned to one of the following groups: 1) Administration of Rotarix at 6 and 10 weeks co-administered with oral polio virus vaccine with no intervention in normal breastfeeding practices before and after receiving vaccine. 2) Administration of Rotarix at 6 and 10 weeks co-administered with oral polio virus. Breastfeeding will not be permitted 45 minutes prior to vaccine administration and 45 minutes after each vaccine administration. 3) Administration of Rotarix at 14 and 18 weeks co-administered with oral polio virus, with no intervention in normal breastfeeding practices before and after receiving vaccine. 4) Administration of Rotarix at 14 and 18 weeks co-administered with oral polio virus. Breastfeeding will not be permitted 45 minutes prior to vaccine administration and 45 minutes after each vaccine administration. Blood and stool samples will be collected from infants and breast milk from mothers. The primary outcome is to determine the sero-conversion rate of anti-rotavirus IgA in different groups of infants.
