Background. Type 2 Diabetes Mellitus (T2DM) and menopause are associated with vitamin D status. Oestrogen decline during menopausal stages promotes hypovitaminosis D. However, the interplay between vitamin D, menopause, lifestyle, and T2DM cannot be overlooked. This study assessed vitamin D status among pre- and postmenopausal T2DM women and determined its association with glycemic control and influence of lifestyle habits on hypovitaminosis D.Methods. This cross-sectional study was conducted at the Komfo Anokye Teaching Hospital, Kumasi, Ghana. Structured questionnaires were administered to 192 T2DM women; blood samples were collected for estimation of 25(OH) D and insulin using ELISA. Fasting blood glucose (FBG), lipid profile, glycated haemoglobin (HbA1c), and calcium were measured. Statistical analyses were performed using Graphpad Prism 6.Results. The prevalence of vitamin D inadequacy was 92.2%. Hypovitaminosis D was more prevalent among the postmenopausal T2DM women (63.8% versus 58.2%). Hypovitaminosis D significantly associated with insulin [R2=0.01760,p=0.0008], HbA1c [R2=0.3709,p=<0.0001], and FBG [R2=0.3465,p=0.0001] in only the postmenopausal women.Conclusion. Vitamin D deficiency is prevalent in pre- and postmenopausal T2DM but higher among postmenopausal women. Adequate vitamin D levels in both groups were associated with improved glucose control while hypovitaminosis D in the postmenopausal women was related to poorer glucose control. Vitamin D screening should be incorporated into management plan for T2DM to serve as an early tool for prevention of vitamin D deficiency.

AbstractVitamin D deficiency is prevalent all over the world, especially in tropical countries. In epileptics, antiepileptic drugs (AED) and associated comorbidities further impact vitamin D status. The aim of this study is to estimate the prevalence of 25(OH) vitamin D deficiency in epileptic children and evaluate probable risk factors. A cross-sectional study of 200 children between 1 and 18 years of age on AED was undertaken in the pediatric neurology clinic of a tertiary care center of Northern India. In all children, serum 25(OH) vitamin D levels, calcium, phosphorus, and alkaline phosphatase were estimated. The deficiency levels of vitamin D were categorized as: deficiency <20 ng/mL, insufficiency 20 to 30 ng/mL, and sufficiency >30 ng/mL. The potential risk factors for hypovitaminosis D, including type of epilepsy, AED regimen (specific medications, polytherapy vs. monotherapy), cerebral palsy, ambulatory status, intellectual disability, body mass index, gender, and vegetarianism were examined. Among the 200 enrolled children (60% boys), 106/200 (53%) were vitamin D deficient. There was no significant relation of vitamin D levels with gender, type of epilepsy, neurological deficit, and type of AED. An inverse relationship of higher phenytoin doses during monotherapy associated with lower vitamin D levels in monotherapy was found, thereby suggesting adverse effect of high doses of phenytoin on vitamin D levels. VDD is common among epileptic children on AED therapy. Vitamin D deficiency is common prevalent among epileptic children on AED therapy, and its detection and treatment correction should be an integral part of epilepsy management.

Vitamin D deficiency is one of the most common medical conditions worldwide. In Tunisia, several studies evaluated Vitamin D status, but this was concerning specific populations (pregnant women, obese or diabetic patients and children with asthma). The only study that evaluated Vitamin D status in a healthy Tunisian population was conducted by Meddeb and al. in 2002. The update of data available, based on the currently recommended limits, is necessary. This study aimed to estimate the prevalence of hypovitaminosis D in a healthy Tunisian population, and correlate the values with potential risk factors. It was conducted on 209 Tunisian healthy subjects. Data collected included clinical characteristics and dietary intakes. We measured 25-hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH), glycemia, creatinine, calcium, phosphorus, proteins and alkaline phosphatase levels. Hypovitaminosis D was retained for 25(OH)D concentrations <30ng/ml. Vitamin D deficiency was defined by 25(OH)D concentrations <10 ng/ml. The prevalence of hypovitaminosis D and vitamin D deficiency were respectively 92.3% and 47.6%. The main factors that were significantly associated with low vitamin D levels in our multivariate analysis were veiling, living in rural areas and sunscreen use. However, sex, age, socioeconomic level, phototype, solar exposure score, smoking and bone mass index, were not statistically associated with hypovitaminosis D. The study of relationship between vitamin D status and serum PTH levels showed a significative and negative correlation (p< 0.005). Given the high prevalence of vitamin D, an adapted health policy is essential. A widespread vitamin D supplementation and food fortification seems to be necessary in Tunisia.

 AIM: This study aimed to assess the prevalence and determinants of osteoporosis [lumbar spine (LS) and femoral neck (FN)] among patients with type 2 diabetes at King Salman Hospital.MATERIALS AND METHODS: One hundred seventy patients with type 2 diabetes were enrolled in this cross-sectional study in the period from the 1st of January until the 1st of July 2015. Patient selection was based on self-report of the previous diagnosis by a physician, being on an antidiabetic agent, or a fasting glucose of 126 mg/dl as per the American Diabetes Association criteria. A dual energy X-ray absorptiometry scan with the bone mineral density (BMD) categorization based on the WHO cut of levels of T-scores and determination of vitamin D levels were performed. A detailed questionnaire was used to collect demographic data.RESULTS: Out of 170 participants, 50 (29.4%) were diagnosed as having osteoporosis, while 68 (40%) were diagnosed with osteopenia. Age was determined as a risk factor for a decreased BMD in patients with osteopenia (odds ratio (OR) = 1.1, 95% confidence interval (CI) = (1.0-1.1), p = 0.039) and osteoporosis (OR = 1.1, CI = 1.0-1.2, p < 0.001). Similarly, oral hypoglycemic agents (OHA) increased the risk of decreased BMD in osteopenia (OR = 2.6; CI = 1.0-6.7; p = 0.023) as well as osteoporosis, (OR = 3.8; CI = 1.3-10.9; p = 0.013), while vitamin D deficiency increased the risk of osteopenia OR = 3.0; CI = 1.2-7.2; p = 0.012). Increased BMI decreased the risk of both osteopenia and osteoporosis (OR = 0.9; CI = 0.9-0.99; p = 0.031 vs. OR = 0.9; CI = 0.80-0.95; p = 0.003).CONCLUSION: Advanced age, OHA and vitamin D deficiency are determinants of decreased BMD in Saudi women with type 2 diabetes, while an increased BMI protects against low BMD.

Background: Recently, we see in our clinical practice that many patients who are coming with generalized body aches and pains and diagnosed as fibromyalgia or chronic fatigue, not adequately responding to treatment. When their vitamin D level was done, it was found to be low and correction of their low vitamin D level improved their symptoms dramatically. Despite abundant sunshine in Bangladesh, allowing vitamin D synthesis all the year round, why our people are developing hypovitaminosis D inspired us to do this current study. Our present study is designed to estimate the prevalence of vitamin D deficiency among adult patients presented with aches & pains as well as to study the association of low vitamin D levels with different socio-demographic parameters.Methods: A cross sectional observational study was conducted among 212 adult patients aged 18 years and above presented with generalized body aches and pains, attended both outpatient and inpatient departments of Popular Medical College Hospital during the period of March’16- August’16 ( 6 months). Association between vitamin D status & the individual specific variables was statistically analyzed.Results: The prevalence of vitamin D deficiency among the study population was found to be100% in all age groups. Among 212 study population, 73.6% were female (n=156) & 26.4% were male (n=56). Mean Vitamin D level among male was 14.29 (SD 4.68) & among female was 12.64 (SD 4.74). The factors associated with severely deficient Vitamin D level were female sex, urban population, &obesity. It is alarming that 64.2% of our study population were totally unaware about the importance of sun exposure.Conclusions: Vitamin D status was associated with a number of socio-demographic variables. Knowledge of these variables may improve targeted education and public health initiatives.J MEDICINE Jan 2018; 19 (1) : 22-29

Aim: Data on the prevalence of vitamin D deficiency in Lithuania are scarce. The aim was to assess the reserves of vitamin D in different age groups of out-patients, regarding the season of the year. Methods: Data on serum 25-hydroxyvitamin D (25(OH)D) levels from blood tests made in 2012–2014 were obtained from one laboratory, and a retrospective cross-sectional analysis was performed. Results: A total of 9581 subjects were included. The mean age of the participants was 33 ± 23 years. The mean levels of vitamin D were higher in males than in females (p < 0.001). The highest mean 25(OH)D levels were in 0–9-year-old group, the lowest were in the 10–19-year-old group and in the group of participants that were 70 years and older (p < 0.001). The lowest vitamin D status was found in January, February, March, and April. The highest status was found in August and September. Overall, vitamin D deficiency, sufficiency, and hypervitaminosis were detected in 67%, 21%, and 12% of cases, respectively. Most cases with hypervitaminosis were in the group of children up to 2 years of age. Conclusion: Vitamin D status demonstrated clear seasonality. Significant sex-related differences of vitamin D statuses were also determined. Vitamin D deficiency was very prevalent in almost all age groups. Young children (aged up to 2 years) are of special interest for further research involving other types of 25(OH)D assays, such as those based on high-performance liquid chromatography (HPLC), since the real prevalence of “true” vitamin D hypervitaminosis in Lithuania’s children is still to be determined.

Abstract Background: Vitamin D is vital for skeletal integrity as well as optimal muscle work. High incidence and prevalence of vitamin D deficiency as well as pelvic organe prolapse are found in postmenopausal women, thus raising the question of whether the entities could be related.Methods: We compared 50 postmenopausal women with pelvic organ prolapse (POP) with 48 age- and weight-matched controls. The clinical assessment of the disorder was performed using the Pelvic Organ Prolapse Quantification system (POP-Q). A questionnaire was filled out by the participants and a blood sample was collected for 25-OH-vitamin D determination.Results: The two groups did not differ significantly in body mass index, but differed significantly in vitamin D blood level concentrations, those being lower in POP patients. A significantly higher prevalence of vitamin D deficiency (25-OH-vitamin D< 50 nmol/l) was found in the test group compared to controls. Higher parity/vaginal deliveries and less caesarean sections were found in patients than in controls. Conclusions: Vitamin D deficiency might be an important associated systemic factor associated to pelvic organ prolapse. The determination of vitamin D levels in postmenopausal women and replenishing its deficiency might also be of importance for the pelvic floor.

Purpose. As the vitamin D status of Algerian postmenopausal women was poorly described, this cross-sectional study investigated the prevalence of low vitamin D status in a sample population. Secondarily, predictive factors of this hypovitaminosis D were explored.Methods. All the 336 selected women ≥ 45 years from Douera were interviewed to get anthropometric and lifestyle data, reproductive and medical history, medications, and calcium/vitamin D intakes. A blood sample was collected to measure 25-hydroxyvitamin D (25(OH)D) concentrations.Results. Approximately 86% of subjects had low vitamin D status (<20 ng/mL). Mean 25(OH)D level was 14.4 ± 5.3 ng/mL with a clear seasonal dynamic and a significant negative correlation with PTH levels (r  = −0.15,p=0.006). A multiple regression analysis using the 25(OH)D cutoff value of 17 ng/mL instead of the generally admitted level of 20 ng/mL was performed to increase statistical power. Other seasons than summer (OR 4.159 and 95% CI 2.456–7.043), obesity (≥30 kg/m2, OR 1.826, 95% CI 1.081–3.083), and veiling (OR 3.526, 95% CI 1.090–11.400) were significantly associated with 25(OH)D concentrations <17 ng/mL.Conclusions. In North Algeria, the abundant sunlight appears insufficient to fully offset hypovitaminosis D risk factors in postmenopausal women, especially obesity and veiling. It suggests the major need to increase vitamin D supplementation in this subpopulation.

Background: Spondyloarthritides (SpAs) encompass heterogeneous diseases sharing similar genetic background, pathogenic mechanisms, and phenotypic features. Vitamin D is essential for calcium metabolism and skeletal homeostasis. Some recent evidences reported supplemental functions of vitamin D, such as modulation of inflammatory reactions. Objective: To analyze published data about a possible association between vitamin D and SpAs. Results: Vitamin D could play a role in immune reactions, influencing both immune and adaptive response. Vitamin D deficiency is more frequent in SpAs than in general population: an active and more severe disease infers patients’ mobility and reduces sunlight exposure. Quiescent inflammatory bowel disease, frequently associated with SpAs, could worsen vitamin D deficiency. All the parameters related to UVB exposure are the most important determinants for vitamin D status and need to be considered evaluating the vitamin D levels in SpAs. Apart from musculoskeletal problems, patients affected by SpAs frequently suffer from other comorbidities, especially cardiovascular diseases and osteoporosis, and vitamin D status could have a relevance in this field. Bone is involved in SpAs with a dualistic role, coexisting trabecular bone resorption and new bone formation. It seems rational to monitor vitamin D levels in SpA subjects and to target it to global health threshold. Conclusion: Literature data were not completely in agreement about a possible relation between poor vitamin D status and onset or worse disease course of SpAs. In fact, these results come from cross-sectional studies, which affect our ability to infer causality. Therefore, large, randomized controlled trials are needed.

Background. A vitamin D deficiency is a global wide health problem. Inadequate vitamin D status leads to serious medical, social and economic consequences and requires timely diagnosis and adequate correction.Aim: to assess the incidence of vitamin D deficiency among the population living in regions of the Russian Federation located at latitudes from 45° to 70° and to study its relationship to various factors (demographic, socio-economic, geographical, etc.).Materials and methods. A multicenter, cross-sectional, randomized study of individuals of both sexes aged 18 to 50 years. The study of 25ОНD level in the blood serum was carried out by INVITRO LLC laboratories using chemilumescent analysis in two stages: in the period from March to May 2020 and from October to November 2020. The first stage of the study involved 500 volunteers (77% women, 23% men). Demographic and socioeconomic characteristics, factors associated with vitamin D levels, were assessed using a specially designed questionnaire.Results. In this article we present the results of the first stage. A countrywide high prevalence of vitamin D deficiency (56.4%) and insufficiency (27.9%) was revealed, that is, 84.3% of the population aged 18–50 years requires cholecalciferol supplementation. The lowest vitamin D status was found in St. Petersburg, Arkhangelsk, Kyzyl and Rostov-on-Don (over 90% of participants had inadequate levels). A decrease in the level of 25ОНD was observed to a greater extent in men than in women (p <0.05), as well as in young people aged 18–25 years (p <0.05). No major association of vitamin D status with anthropometric parameters, the number of days of disability, were not found. However, those who went to tanning beds or were in direct sunlight for at least 30 days a year had higher levels of 25ОНD, and those using sunscreens had lower levels.Conclusion. The data obtained confirms the widespread prevalence of vitamin D deficiency and insufficiency in the country (84.3% of participants), generally not related to the geographical latitude of residence, which indicates the need for vitamin D supplementation in a significant part of the population.
