Abstract Sarcopenia is an age-related disease with an increased risk of mortality. It is emerging that low serum vitamin D (25(OH)D) affects the sarcopenic state in general, but in rheumatoid arthritis (RA), these associations are not understood although the prevalence of vitamin D insufficiency is high in RA. We conducted a cross-sectional study of older female outpatients from our cohort (KURAMA) database. We measured skeletal muscle mass, handgrip strength, and gait-speed to diagnose severe sarcopenia. The serum 25(OH)D concentration was measured using electrochemiluminescence immunoassay. A total of 156 Patients (sarcopenia:44.9%, severe sarcopenia: 29.5%, and without sarcopenia: 25.6%) were enrolled. Classification of vitamin D status at a cutoff point of median 25(OH)D concentration revealed that low 25(OH)D status was associated with a high prevalence of severe sarcopenia and with low measured values of muscle mass, handgrip, and gait-speed. Furthermore, multiple regression analysis identified that low 25(OH)D status was associated with a high prevalence of severe sarcopenia (OR 6.00; 95% CI 1.99–18.08). In components of sarcopenia, both low physical performance and muscle mass were associated with low 25(OH) status. In conclusion, vitamin D levels are associated with severe sarcopenia and its components, and modification of vitamin D status including vitamin D supplementation may play a role in improving sarcopenia in RA.

While vitamin D insufficiency is known to impact a multitude of health outcomes, including HIV-1, little is known about the role of vitamin D-mediated immune regulation in the female reproductive tract (FRT). We performed a pilot clinical study of 20 women with circulating 25(OH)D levels <62.5 nmol/L. Participants were randomized into either weekly or daily high-dose oral vitamin D supplementation groups. In addition to serum vitamin D levels, genital mucosal endpoints, including soluble mediators, immune cell populations, gene expression, and ex vivo HIV-1 infection, were assessed. While systemic vitamin D levels showed a significant increase following supplementation, these changes translated into modest effects on the cervicovaginal factors studied. Paradoxically, post-supplementation vitamin D levels were decreased in cervicovaginal fluids. Given the strong correlation between vitamin D status and HIV-1 infection and the widespread nature of vitamin D deficiency, further understanding of the role of vitamin D immunoregulation in the female reproductive tract is important.

Low serum vitamin D levels have been associated with various vascular diseases. Very little is known its association with acute stroke in Bangladeshi population. We therefore sought to assess whether low serum 25- hydroxyvitamin D, a marker of vitamin D status is associated with acute stroke. We performed a prospective study in Comilla Medical Collage, Comilla, from November 2016 to November 2017. All the patients diagnosed as acute ischemic stroke on the basis of CT scan or MRI of brain. Patients were eligible for inclusion if they were admitted with onset of symptoms within 24 hours. Estimation of 25(OH)D level was done at presentation. The patients were stratified by vitamin D status, >30 as vitamin D sufficient, vitamin D 20-20.9 as insufficient and finally vitamin D<20 as deficient. Multivariate logistic regression analysis revealed that out of the desired 7 variables, smoking, hypertension and low serum vitamin D were found independent predictors for acute stroke with ORs being 1.44, 4.23 and 2.39 respectively. Vitamin D deficiency represents an important risk factor for acute stroke and it might play a causal role in the development adverse events associated with stroke.Medicine Today 2018 Vol.30(1): 34-37

Background: Asthma is a common chronic disorder of the airways that is complex and characterized by variable and recurring symptoms. It is characterized by the occurrence of bronchial hyper responsiveness, airflow obstruction and an underlying inflammation. Several studies have proposed the association of vitamin D with increased incidence of asthma symptoms. Aims and Objectives: This study aimed at determining the serum vitamin D status and biochemical parameters among asthmatic children in Sokoto-Nigeria. Materials and Methods: The study population consisted of 120 subjects including 80 asthmatic children and 40 age-and sex-matched apparently healthy controls from two tertiary Hospitals in Sokoto Metropolis. Serum vitamin D, calcium, parathyroid hormone (PTH), immunoglobulin E (IgE) and magnesium were measured using standard techniques. Results: Mean serum vitamin D and magnesium were significantly (p ˂ 0.05) lower, while serum PTH and IgE were significantly higher (p˂0.001) in asthmatic children than in controls. Vitamin D insufficiency was found to be prevalent among the asthmatic children. There was no significant relationship between the low level of vitamin D and asthma severity. Conclusion: This study observed that, hypovitaminosis D and hypomagnesaemia occurred among asthmatic children, and asthma was more prone in the younger children than in their older counterpart. It is recommended that in order to avoid or limit the rate of children having asthmatic episodes, vitamin D and magnesium supplements should be used in the management of asthmatic children.

Purpose Purpose of this study is to measure the Vitamin D status of healthy adults and to correlate with their lifestyle and feeding habits. Plasma 25-Hydroxyvitamin D (25(OH)D) is the most common marker of vitamin D status of an individual. Deficiency of vitamin D is defined as the serum level less than 20 ng/mL and insufficiency as 30 ng/mL which can be prevented. Design/methodology/approach Vitamin D status of healthy adults (n = 82), both male and females between the age of 18 – 50 years who were attending to the National Transport Authority, Kandy, Sri Lanka from February to March 2016, was measured and correlated with their lifestyle, feeding habits, etc. Findings The mean total serum D (25(OH)D in this study was 40.15 ± 3.74 nmol/l with the mean value of 42.8 ± 28.8 and 37.5 ± 16.6 for women and men, respectively. The serum calcium levels of both female and male were around 8 mg/dl and the serum total protein was 6.5 and 7 g/dl in women and men, respectively. The serum Vitamin D, calcium and total protein were not statistically significantly different between the sexes. In this study, 84 per cent of the total subjects were normocalcemic, and there was no significant relationship between vitamin D levels and their calcium levels. Research limitations/implications This study demonstrates that there was no statistically significant correlation between the serum vitamin D with age, serum calcium or total proteins. The majority of participants who had exposure to the sunlight more than 30 mins/day had sufficient level of vitamin D and less than 30 min/day exposure had deficiency of vitamin D. Daily intake of multivitamin influenced vitamin D status of the study group. Practical implications These findings will implicate the importance of cultural, feed and social habits for the nutritional status of an individual.and there are no reported studies on vitamin D status with reference to the variation of life style. Social implications It is very important to investigate the factors affecting to the vitamin D status of a population as such, vitamin D insufficiency or deficiency can be prevented. In Sri Lanka, the population is consisting with many ethnic groups, different ethnic groups may find some nutritional problems according to their main cultural habits. Originality/value The objectives of this study are to evaluate the Vitamin D status in a group of healthy adults between 20 and 50 years in both men and women and to find out the correlation of their vitamin D status with their lifestyle and feeding habits, etc.
