Filter by:Currently, research on the effect of thiamine administration during transcatheter closure on the structure and function of the left ventricle by examining levels of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in children with left to right shunt congenital heart disease has never been carried out in Indonesia, so it is necessary carried out this research. This research was carried out by administering 100 mg of thiamine once per day to patients post transcatheter closure for 28 days. The parameters assessed were MMP-9, TIMP-1, and echocardiography to assess the structure and function of the left ventricle in CHD patients with left to right shunt lesions.
This research is a clinical trial with a Randomized Controlled Trial (RCT) design. The purpose is to identify the effect of intravenous thiamine administration compared to normal saline placebo on glucagon levels and ROS levels in patients undergoing general anesthesia surgery
Thiamine micronutrient deficiency (TD) can cause a variety of non-specific symptoms and leads to several thiamine deficiency disorders such as heart failure, polyneuropathy, Wernicke's Encephalopathy and generalized weakness and debility. Symptoms are often vague and non-specific such as fatigue, leg swelling, imbalance, confusion, mood disorders, gastrointestinal upset, and weakness. Hospitalized Veterans may be particularly susceptible to TD due to food insecurity and chronic illnesses which cause inflammation and increased metabolic demands. This study aims to determine the prevalence of TD in hospitalized Veterans which has never been done before. The investigators also seek to identify risk factors causing TD including acute and chronic forms of inflammation, food insecurity, and dietary habits. Lastly, the investigators hope to clarify the abnormally low levels of blood thiamine that correlate with symptoms of TD that improve with replenishment.
Thiamine deficiency, including the most severe form infantile beriberi, is a public health concern across South and Southeast Asia, where monotonous diets rely on thiamine-poor white rice. Food insecurity, food preparation and cooking practices, anti-thiamine compound consumption and culturally determined postpartum food restrictions precipitate thiamine deficiency in these high-risk regions. The risk of thiamine deficiency is highest in the first year of life, especially among exclusively or predominantly breastfed infants of mothers who are thiamine deficient themselves, as thiamine content of breastmilk is related to maternal thiamine status. However, diagnosis of infantile thiamine deficiency is challenging due to the highly variable, non-specific clinical manifestations, referred to as thiamine deficiency disorders (TDD), that often overlap with other conditions, resulting in misdiagnosis and missed treatment opportunities, which can be fatal or have irreversible consequences. Considering that breastfed infants are at highest risk, a large proportion of infant deaths could be avoided if: 1) infants with TDD were immediately treated with thiamine when medically indicated and, importantly; 2) thiamine deficiency was prevented by improving thiamine status among breastfeeding women. The latter is important given emerging evidence of long-term neurocognitive deficits of severe and even subclinical thiamine deficiency. In light of these diagnostic uncertainties, it was recognised that a case definition for thiamine responsive disorders (TRD) would help to better identify infants with TDD who would benefit from timely thiamine treatment. This study will test the usefulness of a recently developed case definition for TRD and practical tool in different contexts in Lao PDR where TDD have been reported. Secondly, data on diet, maternal and household risk factors for TDD in different contexts will be used to propose a community risk factor screening tool to better identify populations at risk of thiamine deficiency and help advocate for and guide planning of preventive programmes.
Abstract Background: Thiamine deficiency related disorders are increasingly being reported in countries where polished rice is the main dietary constituents and diet is not balanced in calorie, protein and micronutrients contents. Thiamine deficiency often associated with a sensory-motor neuropathy (dry beriberi) without Wernicke's encephalopathy and cardiac dysfunction. Objectives: The objective of our study will be to evaluate the efficacy of thiamine in patients with clinically suspected dry beriberi. Methods: This study will be a prospective, open labeled, self-controlled clinical trial (quasi-experimental study) carried out in the Neurology and Medicine Ward of Chittagong Medical College Hospital from July 2018 to June 2019. Fifty-five (55) patients of suspected dry beriberi will be recruited as per inclusion and exclusion criteria. All patients will be given 200mg IV Thiamine Hydrochloride per day for 1 week, then oral Tab. Thiamine 100mg twice daily for remaining 11week. They will be evaluated clinically before treatment and followed up at the end of 1 week, 6 week and 12 week after treatment. Assessment will be done by some clinical parameters like leg swelling, muscle cramp, muscle power, squat test, sensory impairments, deep tendon reflexes and by Overall Neuropathy Limitations Scale (ONLS) Score. Pre and post test treatment data will be recorded in a pre-designed case record form. To determine whether any o the difference between pretreatment and post treatment values were statistically significant or not, either Friedman's test or Cochran's Q test will be used. Analysis will be performed with SPSS windows version 23 and statistical significance will be defined as P<0.05 and confidence interval will be set at 95% level. Our study result is likely to sensitize the health professionals of this region about this neglected health issue by increasing awareness of the clinical spectrum of Thiamine Deficiency related Peripheral Neuropathy.
Thiamine (Vitamin B1) is essential for cell function and as a co-factor of the enzyme Pyruvate Dehydrogenase to initiate the Krebs cycle and thus the aerobic metabolism of glucose. We hypothesize that thiamine supplementation improves the clearance of lactate in the first 24 hours after cardiac surgery with extracorporeal circulation in patients with high lactate concentration.
This is a randomized, double-blind, controlled trial design. It was conducted with a main purpose of evaluating the effect of thiamine supplementation on serum lactate and lactate-pyruvate ratio after surgery as direct indicators of tissue perfusion and indirect markers of energy substrate availability for effective mitochondrial function and intubation time as clinical outcome.
In Part 1, subjects will be administered thiamine, thiamine with metformin, and thiamine with trimethoprim. Part 2 will expand on Part 1 and subjects will be administered thiamine and thiamine with trimethoprim. The goal is to determine whether taking a drug and a vitamin together affects the body's ability to absorb, distribute, and eliminate thiamine (Vitamin B1).
A hospital- and community-based study in Luang Prabang, Lao PDR, which will include a group of hospitalized children 21 days to <18 months of age who are diagnosed with symptoms compatible with thiamine deficiency disorder (TDD). Based on the infants' response to thiamine administration, children will be defined as either thiamine responsive disorder (TRD) cases or non-responders. A community-based comparison group of infants in the same age range will be included in the study to serve as a control group for identification of potential risk factors.
Beriberi is a potentially fatal disease caused by vitamin B1 (thiamine) deficiency that still occurs in Southeast Asia despite near eradication elsewhere. Mothers with a diet low in thiamine produce thiamine-poor milk, putting their infants at a high risk of developing thiamine deficiency and beriberi. There is also a growing body of evidence suggesting thiamine deficiency not severe enough to cause clinical symptoms may negatively effect cognitive development and functioning of the infant. Since human milk should be the sole source of nutrition for babies during the first six months, maternal thiamine intake must be improved to combat this disease. The investigators' recent study of thiamine-fortified fish sauce in Cambodia showed that fortification could increase maternal and infant thiamine status'. However, centrally produced fish sauce may not reach the poorest communities who make their own fish sauce, and fish sauce is not consumed in all regions where we find thiamine deficiency. Salt, by contrast, is a common condiment in most regions of the world and has proven to be a successful global fortification vehicle for iodine. Suboptimal maternal thiamine intake puts exclusively breastfed infants at risk of low thiamine status, impaired cognitive development, and infantile beriberi, which can be fatal. Thiamine fortification of salt is a potentially low-cost and sustainable means of combating suboptimal thiamine status; however knowledge gaps must be filled before thiamine fortification can proceed. In this study, mothers will consume thiamine supplements in order to model the thiamine dose required to optimize human milk thiamine concentrations for the prevention of beriberi. Other thiamine biomarkers will be assessed, and usual salt intake will be measured. Finally, the investigators will assess the effects of early-life thiamine exposure on infant neuro-cognitive development.
