Abstract Background The world is now challenging the pandemic of COVID-19 infection. This is the third and most extensive pandemic. Previous studies showed the plausibility of vitamin D prophylaxis and therapy for COVID-19, particularly in settings where hypovitaminosis D is frequent. Recent study from Indonesian showed that the prevalence of vitamin D deficiency was 23.0%. The examination of vitamin D status is not a routine in the Indonesian clinical setting. Methods This study is a case series from confirmed cases of COVID-19 in Bethesda Hospital Yogyakarta Indonesia. The data of clinical symptoms, signs and laboratory examinations were obtained from the electronic medical records. The vitamin D status was measured by Enzyme-Linked Fluorescent Assay (ELFA) method. We searched PubMed and Google Scholar for studies that included terms for Vitamin D and COVID-19. Results The data were obtained from 10 participants consisting of 50% male and 50% female. The mean age was 49.6 years. The prevalence of vitamin D deficiency in this study was 90% (vitamin D levels < 20 ng/mL) and 10% of insufficiency (vitamin D levels < 30 ng/mL). Patients in this study had various symptoms such as fatigue (60%), fever (50%), dry cough (40%), non-specific headache (10%), and diarrhea (10%); have no symptoms (20%); and also had the various chronic diseases as comorbidity such as hypertension (40%), diabetes (10%), COPD (10%), and post stroke (10%). Conclusions All of the COVID-19 patients in this study had hypovitaminosis D. The prevalence of vitamin D deficiency in this case series is 90% and only 1 patient (10%) had vitamin D insufficiency. There are many health benefits of vitamin D and very few adverse effects. Randomized controlled trials need to determine and evaluate this recommendation in preventing or treating COVID-19. Clinicians should continue to treat people with vitamin D deficiency especially in managing COVID-19 patients.

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: 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 Introduction Hypovitaminosis D in pregnancy has been reported to cause various maternal effects, i.e., hypocalcemia, subclinical myopathy, increased risk of preeclampsia (PE), gestational diabetes mellitus (GDM), cesarean sections, and fetal effects, i.e., neonatal tetany, hyperbilirubinemia congenital rickets, infantile rickets, etc. Only few Indian studies are available in this regard. Objective To estimate serum vitamin D levels in pregnant women, cord blood, and study fetomaternal outcomes. Materials and methods A prospective observational study was conducted on 54 consecutive pregnant women and their newborn babies. Serum 25-hydroxy vitamin D [25(OH)D] level was estimated in all women at the time of admission in labor ward. They were followed up to delivery and 48 hours postpartum. Vitamin D was also estimated in cord blood collected during delivery. All results were recorded and analyzed statistically. Results The mean 25(OH)D level in pregnancy was 6.81 ± 7.38 ng/mL. The mean 25(OH)D level in their babies (cord blood) was 6.34 ± 7.05 ng/mL. There was very strong positive correlation between maternal and fetal serum 25(OH)D levels (p-value 0.001, r-value 0.9). Vitamin D deficiency was strongly associated with obesity, PE, and GDM (p-value 0.001). Neonatal jaundice and tetany were also significantly associated with severe vitamin D deficiency. Conclusion Low levels of vitamin D have been observed in pregnant women and their newborn babies. Hypovitaminosis D has been associated with adverse fetomaternal outcomes. As there is a strong correlation of maternal and neonatal levels, supplementing vitamin D in a pregnant women might improve these adverse pregnancy outcomes.

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.

9638 Background: There is emerging evidence in the literature to suggest a protective role of vitamin D in cancer survival. Vitamin D status is not routinely assessed, despite the high prevalence of malnutrition in this population. We hypothesized that malnutrition could contribute to vitamin D deficiency, and therefore expected mean serum 25-hydroxy-vitamin D [25(OH)D] levels to be significantly lower in malnourished oncology patients. Methods: A consecutive case series of 737 cancer patients seen at Cancer Treatment Centers of America between Jan-June 08. Nutritional status was assessed using Subjective Global Assessment (SGA) and serum albumin. SGA categorizes patients into 3 distinct classes of nutritional status; well nourished (SGA-A), moderately malnourished (SGA-B) and severely malnourished (SGA-C). Serum albumin was divided into 2 groups: >=3.6 g/dl and <=3.5 g/dl. Mean serum 25(OH)D was compared across 3 categories of SGA using ANOVA and across 2 categories of serum albumin using 2 sample t test. Results: Of 737 patients, 302 were males and 435 females. The mean age at presentation was 55.7 years (SD = 10.2). The most common cancer types were lung (133, 18%), breast (131, 17.8%), colorectal (97, 13.2%), pancreas (86, 11.7%), prostate (44, 6%) and ovarian (38, 5.2%). The mean serum albumin and serum 25(OH)D was 3.5g/dl (SD = 0.6) and 21.9 ng/ml (SD = 13.5) respectively. There was no significant difference in the mean vitamin D levels across serum albumin (p = 0.76). The mean vitamin D levels across the 3 classes of SGA also showed no statistically significant difference ( Table ). Conclusions: Contrary to what we expected, vitamin D deficiency was found to be prevalent in cancer regardless of nutritional status. No significant differences were found across the 3 classes of SGA. Based on these results, screening for vitamin D deficiency and aggressive vitamin D repletion should be considered for all people with cancer.

Background: Vitamin D deficiency in adult females may increase risk of pre-eclampsia, gestational diabetes, bacterial vaginosis. Various malpresentation, cephalo-pelvic disproportion and difficult deliveries increases the risk of caesarean section. It may also increase the risk of fetal hypovitaminosis D, neonatal rickets and tetany, lower respiratory tract infections, low birth weight, the largest cause of infant mortality in India. This study was under taken to study the impact of vitamin D deficiency on feto-maternal outcome.Methods: The study was conducted in the Department of Obstetrics and Gynaecology, Himalayan Institute of Medical Sciences (HIMS), Swami Ram Nagar, Dehradun, over a period of 12 months. Sample size was 100 pregnant females attending antenatal clinic.Results: Out of 100 subjects, pre-eclampsia was seen in 15, among which 5 (23.80%) had deficient, 9 (13.04%) had insufficient and 1 (10%) had sufficient vitamin D levels. Eclampsia was seen in 3 subjects, out of which 1 (4.76%) had deficient, 2 (2.89%) had insufficient vitamin D status. IUGR was seen in 8 subjects, out of which 4 (19.04%) had deficient vitamin D levels, 4 (5.79%) had insufficient vitamin D status. Neither of the two had sufficient vitamin D status. Deficient vitamin D status with birth weight ≤2.5 kg was seen in 9 (42.85%) subjects and 12 (57.14%) subjects with >2.5 kg Insufficient Vitamin D status was seen in 22 (31.88%) subjects with birth weight ≤2.5 kg and 48 (69.56%) with birth weight >2.5 kg.Conclusions: Prevalence of vitamin D deficiency and insufficiency was noted in this region and its association with pre-eclampsia (23.80%, 13.04% and 10% in deficient, insufficient and sufficient group respectively) was seen. Higher incidence of LSCS was also present among the deficient and the insufficient group.

Sunlight is the main source of vitamin D. Almost 80% of vitamin D3 is produced in the skin. The region of Draa Tafilalet benefits from long daily sunshine time. As such, vitamin D deficiency should be low in this region. However, dressing habits can highly influence vitamin D status. This study aimed to evaluate sun exposure and its relation to vitamin D status among the general population in the region of Draa-Tafilalet, Morocco. Clinical, biological, and sociodemographic data were obtained from 331 adults visiting local healthcare units during the summers of 2019 and 2020. Plasma 25(OH)D2/D3 was measured by immunofluorescence. The prevalence of vitamin D deficiency was 37.5%, while Vitamin D insufficiency represented 56.5%. Most of the studied population (76.4%) had restricting dressing habits and exposed only their faces. statistic tests showed a correlation of vitamin D levels with daily sun exposure (r= 0.308, p<0.001), dressing habits (p<0.001), age (r= -0.141, p=0.01), sex (p<0.001), physical activity level (p=0.003), and BMI (r= -0.298, p<0.001). The study showed a high prevalence of vitamin D deficiency in this region. Similarly, it exposed the effects of restricting clothes and low daily sun exposure on vitamin D status.

Background: Hypovitaminosis D is a very common prevalence in India as well as Middle East. Studies indicate the frequency to be anywhere between 44-96% among adults in Middle east, while in India it is estimated to range in between 50 – 94%. Our report is an attempt to study vitamin D status from two tropical countries; India and Bahrain and present status of vitamin D deficiency as well as insufficiency in a comparison summary.Methods: This retrospective study in our reference lab included data from a total of 2591 samples from Bahrain and 2596 samples from India. Serum vitamin D estimation was done by chemiluminescence immunoassay or CLIA and reported as per the classification given by the US Endocrine Society. Our reference laboratory provides diagnostic services to Bahrain and thus data from both the countries were available for analysis.Results: Our analysis detected vitamin D deficiency to be 66.2% among samples from India in comparison to 41.4% from Bahrain, and this difference was statistically significant at p<0.0001. Further, the average vitamin D levels in the cohort were detected to be higher in Bahrain samples at 24.0±11.6 ng/ml in comparison to samples from India at 18.2±14.4 ng/ml and statistically significant at p<0.0001.Conclusions: Many studies have documented the prevalence of hypovitaminosis D in a region-specific manner. Our report presents the picture of vitamin D status between two tropical countries to highlight the difference in vitamin D deficiency prevalence in two arid and semi-arid regions of the world.
