Purpose of the Work: The main objective of our work is to determine the relationship between osteoarthritis and deficiency of vitamin D in our region in central Europe and to make a database for further researches, to be effective in investigating, controlling, and preventing OA and vitamin D deficiency in our population. Methodology: We perform a retrospective study in adult patients≥25years with osteoarthritis big joints from their health records, which were seen at the osteology clinic of University Hospital Louise Pasteur during the year 2018. The authors analyse the blood tests of Vitamin D level, calcium level, phosphorus level, B ALP, glomerular filtration rate (GFR) levels in the serum of these patients. Results: There were 47 patients with osteoarthritis. All of these patients had Vitamin D deficiency. The mean age of our group is 71 years. 12.8% (7) are male and 87.2% (41)are female. The mean of vitamin D is 24mmol/l (normal range 75-200 nmol/l), Calcium level with in normal range, Phosphorus level mean was within normal range and B ALP level within normal. Conclusion: Osteoarthritis increased by deficiency of vitamin D level in blood serum and increasing with age. Vitamin D is a fat-soluble vitamin that regulates calcium and phosphorus metabolism, maintenance of the normal skeletal and muscular systems. Most of the patients show OA in hip and knee and in advanced age 71 years. Vitamin D supplementation may be a safe method to treat and prevent OA.

Data were pooled from four randomized clinical trials with vitamin D performed in Tromsø with weight reduction, insulin sensitivity, bone density, and depression scores as endpoints. Serum lipids, glycated hemoglobin (HbA1c), and high sensitivity C-Reactive Protein, (HS-CRP) were measured at baseline and after 6–12 months of supplementation with vitamin D 20 000 IU–40 000 IU per week versus placebo. A total of 928 subjects who completed the interventions were included. At baseline the mean serum 25-hydroxyvitamin D (25(OH)D) level in those given vitamin D was 55.9 (20.9) nmol/L and the mean increase was 82.4 (40.1) nmol/L. Compared with the placebo group there was in the vitamin D group at the end of the studies a slight, but significant, increase in HbA1c of 0.04%, an increase in HS-CRP of 0.07 mg/L in those with serum 25(OH)D < 50 nmol/L, and in those with low baseline HDL-C and serum 25(OH)D < 50 nmol/L a slight decrease serum HDL-C of 0.08 mmol/L (P<0.05). No serious side-effects were seen. In conclusion, in subjects without vitamin D deficiency, there is no improvement in serum lipids, HbA1c, or HS-CRP with high dose vitamin D supplementation. If anything, the effect is negative.

Abstract Several studies have demonstrated that higher levels of vitamin D are associated with better prognosis and outcomes in infectious diseases. We aimed to compare the vitamin D levels of paediatric patients with mild/moderate coronavirus disease 2019 (COVID-19) disease and a healthy control group. We retrospectively reviewed the medical records of patients who were hospitalised at our university hospital with the diagnosis of COVID-19 during the period between 25 May 2020 and 24 December 2020. The mean age of the COVID-19 patients was 10.7 ± 5.5 years (range 1–18 years); 43 (57.3%) COVID-19 patients were male. The mean serum vitamin D level was significantly lower in the COVID-19 group than the control group (21.5 ± 10.0 vs. 28.0 ± 11.0 IU, P < 0.001). The proportion of patients with vitamin D deficiency was significantly higher in the COVID-19 group than the control group (44% vs. 17.5%, P < 0.001). Patients with low vitamin D levels were older than the patients with normal vitamin D levels (11.6 ± 4.9 vs. 6.2 ± 1.8 years, P = 0.016). There was a significant male preponderance in the normal vitamin D group compared with the low vitamin D group (91.7% vs. 50.8%, P = 0.03). C-reactive protein level was higher in the low vitamin D group, although the difference did not reach statistical significance (9.6 ± 2.2 vs. 4.5 ± 1.6 mg/l, P = 0.074). Our study provides an insight into the relationship between vitamin D deficiency and COVID-19 for future studies. Empiric intervention with vitamin D can be justified by low serum vitamin D levels.

Background: Vitamin D deficiency is a worldwide health issue and its role as an immune modulator has recently been emphasized. Evidence increasingly indicates the important role of vitamin D in reducing the incidence of autoimmune diseases. However, at this time the search for its role in autoimmune diseases and thyroid is not critical. Objectives: The study aimed to assess the relationship between vitamin D deficiency in Sudanese patients with hypothyroidism. Methods: Analytical case control hospital based study, conducted in Fadil Hospital and Police Hospital, Khartoum city, Khartoum state. The study carried out from March 2018 to September 2018. A total of 100 subjects were enrolled in the study. Vitamin D deficiency was set at levels below 20 ng / ml. Thyroid hormones (TSH, T3 and T4) were assessed in all participants using auto analyzer TOSOH AIA 313,while vitamin D was estimated using ELIZA. The data were analyzed using SPSS version (21). Results: The study included 76(76%) females and 24(24%) males, no significance differences between thyroid profile among study population.75 (75%) deficiency of vitamin D and 25(25%) normal vitamin D. vitamin D deficiency was significantly lower in female than male with( p =0.001). Conclusion: The results indicated that patients with hypothyroidism suffer from vitamin D deficiency significantly associated with the degree and severity of hypothyroidism. This encourages the desirability of vitamin D supplementation and recommends the detection of vitamin D deficiency for all hypothyroidism patients.

ABSTRACTBackgroundCOVID-19 has emerged as a global pandemic, affecting nearly 104 million people worldwide as of February 4th 2021. In previous published studies, the association between the mean Vit D status of each country and COVID-19 infection rate, and mortality among the adult population in European countries was examined. The aim of this study was to re-examine the relationship between the Vit D status of each country and COVID-19 infection, recovery, and mortality using updated data and a different methodological approach.MethodsInformation only form the last decade on Vit D concentration/deficiency for each country was retrieved through literature search on PubMed® database. As of February, 4th 2021, COVID-19 infections and mortalities per one million population as well as total recoveries were extracted from the Worldometer website. The association between vitamin D deficiency and COVID-19 infection, recovery, and mortality were explored using correlation coefficients and scatterplots.FindingsThe prevalence of vitamin D deficiency among European countries ranged from 6.0 (Finland) to 75.5% (Turkey), with several countries facing more than 50% of vitamin D deficiency among their population. Non-significant correlations were observed between the number of COVID-19 infections (r=0.190; p=0.374), recoveries (rs=0.317, p=0.131), and mortalities (r=0.129; p=0.549) per one million population, with the prevalence of vitamin D deficiency.InterpretationPrevalence of vitamin D deficiency was not significantly associated with either number of infections, recoveries or mortality rate of COVID-19 among European countries. Thus, it is an important parameter to be considered when implementing preventive measures to face COVID-19.FundingNone

Introduction: The rise in prevalence of obesity has occurred concomitantly to that of vitamin D deficiency (VDD). The aim of this narrative review was to describe the relationship between obesity and such related diseases as VDD in adolescents, in an effort to warn of the risks of this deficiency during this period of growth and development.Methods: We searched the electronic databases PubMed, Medline, Scielo, Science Direct and Lilacs for articles from between 2000 and 2015 on the topics obesity and obesity-related diseases and VDD in adolescents. We included articles written in English, Spanish and Portuguese of the analytical variety (transverse and longitudinal), systematic reviews, meta-analysis and controlled clinical trials on humans, and excluded studies that were done on animals, inconclusive or with undefined methodology.Results: We produced an overview of VDD in obesity, in cardiovascular diseases, in diabetes mellitus, in systemic hypertension, and in dyslipidemia. The prevalence of VDD was considered high in obese adolescents and their relationship with the obesity and related diseases was found in adolescents. These findings forewarn of possible clinical repercussions in the health of the adolescents, foremost because of how essential vitamin D is to growth and development, and for its interaction with obesity and obesity-related diseases.Conclusion: The worldwide rise in the obesity rate alongside the progressively increasing of vitamin D deficiency in adolescents is alarming. This relationship of VDD with the obesity and related diseases was found in adolescents. Vitamin D supplementation is considered promising measure to take with obese adolescents.

Sarcopenia is a prevalent condition in patients with Crohn’s disease (CD), representing an independent predictor factor for the development of major postoperative complications. Thus, a proper assessment of the muscle strength, by using different validated tools, should be deemed an important step of the clinical management of these patients. Patients with CD are frequently malnourished, presenting a high prevalence of different macro- and micro-nutrient deficiencies, including that of vitamin D. The available published studies indicate that vitamin D is involved in the regulation of proliferation, differentiation, and regeneration of muscle cells. The relationship between vitamin D deficiency and sarcopenia has been extensively studied in other populations, with interesting evidence in regards to a potential role of vitamin D supplementation as a means to prevent and treat sarcopenia. The aim of this review was to find studies that linked together these pathological conditions.

Aim: Vitamin D affects the secretion of antimicrobial peptides associated with toll-like receptor (TLR), which have antiviral effects. It has been suggested that vitamin D may affect the susceptibility of the host to varicella zoster virus (VZV) and the clinical course of zona zoster. Materials and Methods: In this study, 101 patients who were diagnosed with zona zoster at the dermatology outpatient clinic and had a vitamin D result at the time of diagnosis and a control group of 100 people were included. Results were analyzed statistically. Results: The 25-OH vitamin D levels of the patients ranged from 2.37 to 32.98 µg / L and the mean value was 14.25 ± 7.20 µg / L. In the control group, 25-OH vitamin D levels ranged between 10.3 and 44.25 µg / L, and the mean value was 24.9 ± 6.24 µg / L. 25-OH vitamin D levels in the patient group were significantly lower than the levels in the control group. (p <0.001) Conclusion: This study revealed that 25-OH vitamin D levels were significantly lower in patients with zona zoster compared to the control group. 25-OH vitamin D deficiency may increase the risk of VZV reactivation, and vitamin D supplementation in patients with vitamin D deficiency in zona zoster may help the mild course of the disease.

BackgroundAs an immune system regulator, vitamin D is commonly deficient among patients on peritoneal dialysis (PD), which may contribute to their impaired immune function and increased risk for PD-related peritonitis. In this study, we aimed to investigate whether vitamin D deficiency could predict the risk of peritonitis in a prospective cohort of patients on PD.MethodsWe collected 346 prevalent and incident PD patients from 2 hospitals. Baseline demographic data and clinical characteristics were recorded. Serum 25-hydroxyvitamin D (25[OH]D) was measured at baseline and prior to peritonitis. The mean doses of oral active vitamin D used during the study period were also recorded. The outcome was the occurrence of peritonitis.ResultsThe mean age of patients and duration of PD were 58.95 ± 13.67 years and 28.45 (15.04 – 53.37) months, respectively. Baseline 25(OH)D level was 16.15 (12.13 – 21.16) nmol/L, which was closely associated with diabetic status, longer PD duration, malnutrition, and inflammation. Baseline serum 25(OH)D predicted the occurrence of peritonitis independently of active vitamin D supplementation with a hazard ratio (HR) of 0.94 (95% confidence interval [CI] 0.90 – 0.98) after adjusting for recognized confounders (age, gender, dialysis duration, diabetes, albumin, residual renal function, and history of peritonitis). Compared to the low tertile, middle and high 25(OH)D level tertiles were associated with a decreased risk for peritonitis with HRs of 0.54 (95% CI 0.31 – 0.94) and 0.39 (95% CI 0.20 – 0.75), respectively.ConclusionsVitamin D deficiency evaluated by serum 25(OH)D rather than active vitamin D supplementation is closely associated with a higher risk of peritonitis.

Abstract.The relationship between Hashimoto’s thyroiditis and vitamin D has been demonstrated in several studies. The aim of the present study was to evaluate vitamin D concentrations in patients with Hashimoto’s thyroiditis, the effect of vitamin D therapy on the course of disease, and to determine changes in thyroid autoantibody status and cardiovascular risk after vitamin D therapy. We included 75 patients with Hashimoto’s thyroiditis and 43 healthy individuals. Vitamin D deficiency is defined as a 25-hydroxy vitamin D (25(OH)D3) concentration less than 20ng/mL. Vitamin D deficient patients were given 50.000 units of 25(OH)D3 weekly for eight weeks in accordance with the Endocrine Society guidelines. All evaluations were repeated after 2 months of treatment. Patients with Hashimoto’s thyroiditis had significantly lower vitamin D concentrations compared with the controls (9.37±0.69 ng/mL vs 11.95±1.01 ng/mL, p < 0.05, respectively). Thyroid autoantibodies were significantly decreased by vitamin D replacement treatment in patients with euthyroid Hashimoto’s thyroiditis. Also, HDL cholesterol concentrations improved in the euthyroid Hashimoto group after treatment. The mean free thyroxine (fT4) concentrations were 0.89±0.02 ng/dL in patients with Hashimoto’s thyroiditis and 1.07±0.03 ng/dL in the healthy control group (p < 0.001). The mean thyroid volumes were 7.71±0.44 mL in patients with Hashimoto’s thyroiditis and 5.46±0.63 mL in the healthy control group (p < 0.01). Vitamin D deficiency is frequent in Hashimoto’s thyroiditis and treatment of patients with this condition with Vitamin D may slow down the course of development of hypothyroidism and also decrease cardiovascular risks in these patients. Vitamin D measurement and replacement may be critical in these patients.

This review summarizes studies discussing vitamin D status in adults and reveals that vitamin D deficiency/insufficiency is highly prevalent in adults and that current fortification and supplementation policies are inadequate. Background and aims: Studies suggest a crucial role for adequate vitamin D status in various health conditions including bone metabolism, cancer, cardiovascular diseases, and allergies. However, relatively little is known about poor vitamin D status and unmet needs in adults. This report aims to highlight the contribution of epidemiologic studies (through the identification of health effects and societal burden) to the development of vitamin D fortification and supplementation policies and reveal unmet global challenges in adults. Methods: In order to assess worldwide vitamin D status in adults, the search strategy combined the medical literature database MEDLINE (using PubMed) for the time period between January 1, 1980 and February 28, 2011, using the key words “vitamin D” “deficiency” and “insufficiency”, and included articles in which access to full text was possible and in which healthy adults were assessed according to one of four commonly used vitamin D threshold classifications. Results: This report reveals that vitamin D deficiency occurs in 4.10 % [95 % CI (confidence interval), 3.93 %, 4.27 %] to 55.05 % (54.07 %, 56.03 %) of adults, while insufficiency occurs in 26.07 % (24.82 %, 27.33 %) to 78.50 % (77.85 %, 79.16 %), depending on the classification used. However, lack of overlap in CIs and high value of I2 statistics indicate considerable heterogeneity between studies. Further, certain populations (i. e. dark-skinned individuals, immigrants, and pregnant women) may be at higher risk for poor vitamin D status. Conclusion: Current policies for vitamin D supplementation and fortification are inadequate and new guidelines are required to improve vitamin D status in adults.
