There are about 330 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.
Inflammation can influence several biochemical measurements those commonly used to interpret micronutrient status in children. Our primary objective is to investigate the effects of inflammation on several biochemical measurements used to interpret micronutrient status in children. A total of 40 infants (9-18 mo of age) will participate in this study. Investigators will use PENTA vaccines as a means to induce controlled inflammation (closely mimic to natural infection). PENTA is a combination of five different vaccine antigens (Hepatitis B (HBV)/ Haemophilus influenza type b (Hib) / Tetanus-Diphtheria-whole cell Pertussis (TDwP)). The investigators will also use two different stable isotopic retinols for the assessment of total body vitamin A stores. Baseline blood samples (5 mL) will be obtained from all infants and then randomly selected 30 infants will receive PENTA vaccines, while the other 10 infants will receive no vaccines. 24 hours after vaccination a finger-prick blood sample will be obtained from the infants in the vaccinated group to measure CRP and on the same day, blood samples (5 mL) will be obtained from infants who develop inflammation (CRP> 5mg/L) in the vaccine group and also from infants in the control group. Thus estimated plasma micronutrients and vitamin A stores before and after inflammation will calculate the effects of inflammation on the interpretation of micronutrient deficiencies based on biochemical indicator assessment.
Background: Chronic Obstructive Pulmonary Disease (COPD) is a major cause of morbidity and mortality throughout the world which is a preventable as well as treatable disease. It has some important extra pulmonary effects which may contribute to the magnitude of the severity of this disease. Standard therapeutic treatment alone does not optimize its remedy. Vitamin D3 has been found to improve the physical efficiency of patients with various morbid disorders, including respiratory ailments. Hypothesis:Vitamin D3 administration in stable patients with moderate COPD improves lung function variables along with exercise tolerance. Objectives: To evaluate the effects of Vitamin D3 on lung functions and exercise tolerance in patients with stable moderate COPD. Methods: For this, a prospective interventional randomized double blinded study will be carried out on 46 vitamin D3 deficient (serum 25 dihidroxycholecalceferol less than 30 ng/ml), male, stable (diagnosed patient, who has not experienced any acute exacerbation , hospitalizations , urgent care visits, or changes in routine medication within 4 weeks prior to study), moderate (post bronchodilator FEV1/FVC<0.70 of predicted value and FEV1=50 to 79% of predicted value) COPD patients (age ≥40 years), who will be selected from the Out Patient Department (OPD) of the National Institute of Diseases of Chest and Hospital (NIDCH) and will be grouped as A (control) and B (study) groups, respectively. All the patients will be again designated as A0, A90 (without D3) and B0, B90 (with D3) for before and after 90 days of follow up. All the participants will be matched in terms of duration of COPD, history of smoking, occupation and socioeconomic status. Along with the standard pharmacological treatment of COPD, the patients of the 'Study group' will be prescribed for 80000 IU of oral vitamin D3 pre week for consecutive 3 months. Along with this, all patients both the groups will be advised to continue ad lib (according to their own choice) diet. At the very 1st day of the study, the lung functions will be assessed by measuring Forced vital capacity (FVC), Forced expiratory volume in one second (FEV1), Forced expiratory ratio (FEV1/FVC%), Peak expiratory flow rate (PEFR) and Forced mid expiratory flow of FVC(FEF25-75%), with a portable digital spirometer. In addition, exercise tolerance will be assessed by change in 6 Minute Walk Distance (6MWD) in 6 Minute Walk Test (6MWT). Changes in peripheral capillary oxygen saturation (SpO2) by Pulse Oximeter and degree of dyspnoea by Modified Borg Scale (MBS) will also be measured both before and after 6MWT to evaluate their change in both the groups. All these variables will be measured again among same 46 patient after 90 days standard pharmacological treatment of COPD with D3 intervention (B group) and also without D3 intervention (A group). For statistical analysis, Chi-square test, independent sample 't' test between two groups, paired Student's 't' test within two specific measurements of different durations of each group ,will be done. In the interpretation of results, ≤0.05 level of probability (p) will be accepted as significant.
The purpose of this project is to systematically collect clinical and nutritional outcomes information on patients treated for Shigella infection so that physicians and clinical laboratories can better define which Shigella infections are "resistant" to antibiotics and which are "susceptible", focusing on azithromycin a last-line drug to treat drug resistant Shigella
Title:Impact of vitamin D administration on cardiac autonomic tone in Asthma Chronic Obstructive Pulmonary Disease (COPD) Overlap patients: A blinded randomized control trial. Background: Respiratory disease is closely associated with cardiovascular disease. Reduced Heart Rate Variability (HRV), reflecting impaired autonomic activity have been reported in both asthma and COPD. Vitamin D deficiency is a common feature in Asthma COPD Overlap (ACO) patient. Relationship between vitamin D deficiency and low HRV has been reported. Vitamin D administration has been reported to improve cardiac autonomic modulation in healthy subjects in response to external stressor. Objective: To assess the changes in cardiac autonomic tone after vitamin D administration for 90 days in vitamin D deficient ACO patients. Hypothesis:Null: Vitamin D administration does not have impact on cardiac autonomic tone in vitamin D3 deficient ACO patient. .Method: This randomized controlled trial will be conducted by Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka from September' 2017 to August' 2018. For this study, a total number of 60 subjects (age > 40 years, both male and female) will be randomly selected. 30 diagnosed vitamin D deficient Asthma COPD Overlap (ACO) patients will form group A and another 30 diagnosed vitamin D3 deficient ACO patients with similar age, sex, (Body Mass Index) BMI will constitute control group B. Patients of study group B0 will take vitamin D3 with a prescribed schedule for 3 months and followed up after 3 months (group B90). On the other hand patients of group A1 will be given placebo and followed up after 3 months (group A90). All these patients will continue their medication prescribed by physician during these 3 months. On the basis of data recording - group B1 and group B90 will constitute pre and post vitamin D group whereas group A0 and group A90 will represent pre and post placebo follow up at day 0 and day 90. Cardiac autonomic nerve function will be assessed by recording ECG & Heart Rate Variability (HRV) analysis by a data acquisition device, powerlab 8/35, AD instruments, Australia. HRV measures of all patients will be recorded at baseline.Then after 3 months of follow up it will be recorded in both groups at day 90. Serum 25(OH)D level will be measured of all subject at day 0 and day 90. For statistical analysis unpaired and paired "t" test will be done by using Microsoft Office Excel Word version 2016

Title: Effect of Vitamin C upon Selective Serotonin Reuptake Inhibitors (SSRIs) - treated Obsessive Compulsive Disorder (OCD) patients. Purpose of the study: This study aims to examine the effect of vitamin C upon Selective Serotonin Reuptake Inhibitors (SSRIs) - treated Obsessive Compulsive Disorder patients. Method: It will be a prospective type of interventional study to to assess the effects of vitamin C along with SSRIs upon OCD patients. The study will be conducted in the Department of Pharmacology and Department of Psychiatry, BSMMU, from September 2017 to February 2019. A total of 90 OCD patients will be selected according to inclusion and exclusion criteria. The patients will be divided randomly into 2 groups: group A and group B. Group A will consist of 45 patients who will receive only SSRIs orally daily and group B would consist of 45 patients who will receive vitamin C, 500 mg BID orally daily along with SSRIs for 8 weeks. To see the effects of Vitamin C, Yale-Brown score of obsessive-compulsive disorders (Y-OCD) would be assessed by Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at baseline (before vitamin C administration) and 8 weeks after intervention. Biochemical parameters of oxidative stress markers such as plasma malondialdehyde (MDA), plasma reduced glutathione (GSH) and plasma vitamin C level would also be performed at baseline (before vitamin C administration) and 8 weeks after intervention. Ethical consideration: The study will follow the principles of the Declaration of Helsinki and of the World Medical Assembly. Patients will be informed about the study in easy language and then informed consent will be taken. This study has no potential risk to the patients. Confidentiality will be strictly maintained.
