Mean Percentage of Levothyroxine Dosage Increase in Patients With Hypothyroidism Started on Enteral Feeding

2015-10-19 13:03:44 | BioPortfolio


The study aims to describe the changes in Levothyroxine dosage requirements in patients with hypothyroidism started on enteral feeding, and assess whether giving levothyroxine on empty stomach affects the mean percentage increase expected in Levothyroxine dosage in these patients.


The study will be a Randomized Controlled trial comparing the mean percentage of Levothyroxine dosage change in hypothyroid patients after the starting of enteral feeding in an inpatient setting in two different groups: a control group where Levothyroxine will be administered with continuous enteral nutrition, and an intervention group where enteral nutrition will be held for two hours before and two hours after the Levothyroxine administration.

The enrollment of eligible patients will be over two to three years and follow up will continue for the duration of the hospital stay or 12 weeks, which ever occurs earlier. Eligible patients will have thyroid function tests at enrollment (within three days of the starting of the tube feeding) and afterwards weekly. Levothyroxine dosage will be adjusted by the endocrinology research team according to the thyroid function results. Initial Levothyroxine dosage and subsequent dosages will be recorded and the mean percentage decrease or increase of Levothyroxine dosage required will be measured in each group. An eventual difference between the two groups mean percentage change will be tested for statistical significance.

Medical and Biotech [MESH] Definitions

A condition in infancy or early childhood due to an in-utero deficiency of THYROID HORMONES that can be caused by genetic or environmental factors, such as thyroid dysgenesis or HYPOTHYROIDISM in infants of mothers treated with THIOURACIL during pregnancy. Endemic cretinism is the result of iodine deficiency. Clinical symptoms include severe MENTAL RETARDATION, impaired skeletal development, short stature, and MYXEDEMA.

Chronic autoimmune thyroiditis, characterized by the presence of high serum thyroid AUTOANTIBODIES; GOITER; and HYPOTHYROIDISM.

A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA.

Pathological enlargement of the LINGUAL THYROID, ectopic thyroid tissue at the base of the TONGUE. It may cause upper AIRWAY OBSTRUCTION; DYSPHAGIA; or HYPOTHYROIDISM symptoms.

Defective development of the THYROID GLAND. This concept includes thyroid agenesis (aplasia), hypoplasia, or an ectopic gland. Clinical signs usually are those of CONGENITAL HYPOTHYROIDISM.
