Abstract Background In recent years, hypovitaminosis D has been linked to many chronic diseases, including metabolic syndrome (MetS). However, there are considerable discrepancies in the study findings. Therefore, the present study investigated the association between vitamin D status and MetS in a cohort of Iranian adults followed from 2001 to 2013. Method This study was designed using the data from Isfahan cohort study which is an ongoing cohort of Iranian adults. For this study, 170 cases with MetS were selected from those who were free of MetS in 2001 but developed the condition in 2013. Controls (n=200) were selected from those who were free of MetS throughout the study period. Various biochemical parameters, including serum vitamin D concentrations, and socio-demographic information were assessed in 2001, 2007 and 2013. Generalized Estimating Equations was used to analyse the longitudinal association between vitamin D status and MetS. Results The subjects with MetS had higher levels of serum vitamin D [25(OH)D], total cholesterol, triglyceride, body mass index, waist circumference, systolic and diastolic blood pressure than that in the control subjects in 2001, while they had lower physical activity levels. A family history of hyperlipidemia was also more prevalent in the subjects with MetS. This study did not find any association between MetS and serum vitamin D status after controlling for potential confounders. Conclusion In spite of the high prevalence of vitamin D deficiency and MetS among studied population, this study failed to show any association between vitamin D status and MetS and/or its components. Randomized controlled trials are warranted to investigate the potential association more meticulously.

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.

Background: Inverse relationship between metabolic syndrome (MetS) and 25-hydroxyvitamin D (25(OH) D) levels is controversial. Hypovitaminosis-D has long been suspected as a risk factor for glucose intolerance. Aim: A randomized double blind placebo controlled study to evaluate effects of vitamin D supplementation on insulin resistance in subjects with hypovitaminosis-D and MetS. Materials and Methods: Subjects were randomized to receive either oral 25(OH) D3 supplement (60000 (IU) per week for 8 weeks followed by 60,000 IU monthly for 4 months) or a placebo for six months. The parameters measured were blood pressure, vitamin D, fasting blood sugar (FBS), insulin, homeostasis model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI), body mass index (BMI), and waist circumference (WC). Results: There were no significant changes in parameters of vitamin-D group compared to placebo group except serum vitamin-D was significantly increased in vitamin-D group (p < 0.0001). In vitamin-D group, mean WC at baseline was 95.9 ± 6.66, which significantly changed to 94.6 ± 7.47 (p = 0.001). Mean BMI at baseline was 29.1 ± 4.06 which significantly changed to 28.5 ± 4.16 (p = 0.001). The mean vitamin-D concentration at baseline was 15.4 ± 9.03 which significantly (p < .0001) increased to 26.1 ± 11.8. In placebo group mean insulin levels was 10.7 ± 4.81IU / L which increased significantly (p = 0.03) to 15.4 ± 14.0. Mean QUICKI at baseline was 0.34 ± 0.03 which decreased significantly (p = 0.02) to 0.32 ± 0.03. Conclusion: In this study the relationship between vitamin D supplementation and MetS or IR was not established. Whether achieving vitamin D sufficiency in large population-based trials with a longer duration would produce more favorable results needs to be assessed.

Abstract Background Anti-seizure medication (ASM) treatment is one of the significant risk factors associated with abnormal vitamin D status in epilepsy patients. Multiple studies have shown that adult epilepsy patients can exhibit vitamin D deficiency. However, there are few reports investigating pediatric epilepsy patients. In this study, we aimed to identify risk factors related to hypovitaminosis D in pediatric epilepsy patients in Thailand. Methods A cross-sectional retrospective cohort study was conducted in 138 pediatric epilepsy patients who received anticonvulsants from April 2018 to January 2019. Demographic data, seizure types, puberty status, physical activity, duration, and types of anti-seizure medications were analyzed. Patients with abnormal liver function, abnormal renal function, and who received vitamin D supplements or ketogenic diet containing vitamin D were excluded. Levels of serum vitamin D (25(OH)D) were measured. Results All 138 subjects were enrolled, the age ranged from 1.04 – 19.96 years; (mean = 9.65 ± 5.09), the mean serum 25(OH) D level was 26.56 ± 9.67 ng/ml. The prevalence of vitamin D deficiency was 23.2% and insufficiency was 47.8% respectively. Two risk factors—puberty status (OR 5.43, 95% CI 1.879-15.67) and non-enzyme-inhibiting ASMs therapy (OR 3.58, 95% CI 1.117-11.46)—were significantly associated with hypovitaminosis D, as shown by multivariate analyses. Conclusions Our study reports the high prevalence of hypovitaminosis D in pediatric epilepsy patients in Thailand despite being located in the tropical zone. These findings can guide clinicians to measure vitamin D status in pediatric epilepsy patients particularly when they reach puberty and/or are using non-enzyme-inhibiting ASMs therapy. Early detection of vitamin D status and prompt vitamin D supplementation can prevent fractures and osteoporosis later in life. Trial registration TCTR20210215005 (http://www.clinicaltrials.in.th/).

Background: As a neuroactive steroid, vitamin D is essential for optimal neuronal functioning1. Its immunomodulatory and neuroprotective effects aid in reduction of proconvulsant cytokines, membrane excitability and seizure prevention2-3. Deficiency plays an important role in neurological and psychiatric illnesses, though clinical manifestation with seizures and psychosis have not been described. Methods: A 61-year-old female presented with 3-day history of confusion, insomnia and new onset seizure. She was noted to have poor dentition, deformed nail bed and multiple ecchymosis. Neurologically, there were brisk reflexes with some spread. She worsened with frequent seizures and psychosis. Results: Laboratory investigation showed serum Vitamin D level of 19nmol/L, hemoglobin of 70g/L. MRI head revealed T2 hyperintensities in bilateral anterolateral temporal lobes and EEG consistent with bitemporal lobe epilepsy. Autoimmune and infectious work up were negative. Treatment with antipsychotics, several antiepileptics, high dose Vitamin-D and iron supplements were initiated. Initially, she remained unresponsive to neuro/psych medications. Improvement in clinical symptoms was noticed in 4th week of admission, with complete resolution of MRI, EEG findings. Conclusions: Evidence surrounding hypovitaminosis D and risk on the central nervous system continues to grow. This case highlights the significance of vitamin-D on brain processes and its neurological manifestations in state of deficiency. 1. Kalueff.A.,2006. 2. Garcion. E, 2003. 3. Eyles, D., 2013.

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.
