Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Thus, the aim of the current study is to assess the influence of vitamin D deficiency and, consequently, of serum calcium deficiency in the body composition, muscular activity, bone mineral density, fatigue, and exercise tolerance of CD patients. Secondly, it also aims to determine the impact of vitamin D supplementation on this population.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This will be a clinical, randomized, controlled, and double-blind trial comprising a consecutive sample of 110 CD patients in remission and low serum vitamin D levels treated by the Gastroenterology team of the Inflammatory Intestinal Disease Clinic at the University Hospital (HU/CAS), Federal University of Juiz de Fora (UFJF). These patients will be divided into two groups with 55 patients each. One group will receive vitamin D supplementation (50.000 UI/week) and the other will receive placebo. Upon the approval by the Ethics Committee of the UFJF, the study aims and procedures will be previously explained to the individuals, who will sign an informed consent form.
The sample size was based on the handgrip strength test, assuming an alpha risk of 5 % and beta risk of 80 %, standard deviation of 2.5, and a difference in magnitude of 30% of response between intervention and placebo group, the sample size needed was 45 patients in each group. Therefore, considering potential losses, 55 patients will be recruited for each group, requiring a total of 110 volunteers.
Study procedure
Phase 1. Assessment All patients in the study will be subjected to the following tests: a. clinical assessment; B. biochemical assessment; c. body composition assessment/anthropometry; d. bone mineral density assessment; e. peripheral muscle strength assessment; f. fatigue assessment; g.Exercise Tolerance Testing
Clinical Assessment of the Disease The following data will be collected in the initial assessment: age, gender, CD duration, data related to the Montreal Classification (age at the time of diagnosis, disease behavior and location), glucocorticoid use and number of exacerbations in the previous year. The inflammatory activity assessment will be held according to the Harvey-Bradshaw Index, When the score is less than 5, the disease is considered to be inactive.
Biochemical Assessment The participants will be instructed to fast 12 hours prior to the blood sampling for analysis. A 5 ml venous blood sample will be collected from the patients in order to determine biochemical parameters. The University Hospital routine laboratory will analyze the venous blood, the levels of C-reactive protein (CRP), calcium, 25-hydroxyvitamin D, parathyroid hormone (PTH) and inflammatory cytokines such as Interleukins (IL) 17, IL 6 and Tumor necrosis factor alfa (TNF-α) . CRP and serum calcium are routinely evaluated in all CD patients under follow-up in the inflammatory bowel disease clinic at HU/CAS.
The following reference values will be taken into consideration regarding 25-hydroxyvitamin D: \< 20ng/mL = deficiency, between 21 and 29 ng/mL = insufficiency, and \> 30 ng/mL = satisfactory.
Bone Mineral Density Assessment A bone densitometer, Lunar Prodigy Primo (pr + 351035), will be used to measure the patients' bone mineral density (BMD), expressed in g/cm2, by dual-energy x-ray absorptiometry (DXA). The double-energy X-ray densitometry of the skeleton or specific sites such as the spine and the hip is based on the X-rays absorption by the calcium crystals in the bone. The lumbar spine regions between L1 and L4 and those of the total proximal femur will be assessed. The examination will be held under appropriate conditions, according to the technical quality controls. The coefficient of variation for the lumbar spine and total proximal femur will be obtained based on these results. The low BMD will be defined by the reduction greater than -2.0 standard deviations from the reference value mean of healthy individuals, adjusted according to height, age and gender (Z score), in compliance with the official positions of the International Society for Clinical Densitometry (ISCD).
Body Composition Assessment/Anthropometry The assessment will be held through the Quantum BIA (bioelectrical impedance analysis) bioimpedance device. The device is four-pole, has digital display, and provides resistance and reactance values. Total and segmental body composition parameters will be also assessed by DXA expressed in kg.
Muscle Strength Assessment The peripheral muscle strength will be assessed through the maximum voluntary handgrip strength using hand-held dynamometry (HHD), which consists of a simple and objective test that estimates the skeletal muscle function. The Jamar's hydraulic dynamometer will be used, since it is recommended by the American Society of Hand Therapists (ASHT) and is considered the most accurate and precise instrument used to assess HHD .
Fatigue Assessment The questionnaire by Chalder et al. (Annex), which was validated in Brazil will be applied to assess fatigue.
Exercise Tolerance Testing The exercise capacity is assessed by the walking test with progressive loading or Shuttle Walk Test.
Phase 2. Intervention A double-blind, randomized, placebo-controlled study will be performed. After the evaluation of serum vitamin D levels, patients with vitamin D below 30ng/mL will be randomized into two groups. One group will receive supplementation with cholecalciferol (vitamin D3) tablets and the other group will receive placebo. Those will be provided at no cost to the patients. The dosage of 1.500-2.000 IU (International Units) vitamin D/day is recommended in order to meet the need of vitamin D above 30ng/mL in adults. However, a dose at least 2 to 3 times higher is recommended for CD patients due to malabsorption, significant loss of adipose tissue and use of glucocorticoids. Thus, the dose of 50,000IU/week will be administered in a single dose.
The contraindications and precautions on the use of vitamin D will be respected, namely: hypersensitivity to the D-group vitamins, hypercalcemia, hypercalciuria and metastatic calcification; and interactions with digitalis, thiazides, and anticonvulsant and antacid medications.
Despite the possible interference of the skin melanin concentration in vitamin D absorption, no evidence was found to support the differentiated supplementation between Afro descendant and Caucasian individuals.
The patients drawn to the placebo group will receive inert content tablets without therapeutic effect. After the study completion, these control patients will receive complete treatment for hypovitaminosis D.
Throughout the intervention phase, both the treated group and the control group patients will be monitored by phone every 15 days in order to optimize their adhesion.
Phase 3. Reassessment At the end of 6 months of supplementation with cholecalciferol (vitamin D3), this subgroup of patients will be subjected to the same assessments performed in phase 1.
The sample size was based on the handgrip strength test, assuming an alpha risk of 5 % and beta risk of 80 %, standard deviation of 2.5, and a difference in magnitude of 30% of response between intervention and placebo group, the sample size needed was 45 patients in each group. Therefore, considering potential losses, 55 patients will be recruited for each group, requiring a total of 110 volunteers.
