Summary Recently published data indicate that vitamin D abnormalities are common in sarcoidosis patients. The purpose of this study was to compare serum vitamin 25(OH)D levels among sarcoidosis patients with different clinical cour - ses of the disease. The study also included the first observations on cognitive functions (i.e. depression and fatigue syndrome) in relation to vitamin D deficiency in sarcoidosis patients. At the Biochemical Laboratory of the Clinical Center of Serbia, Belgrade, vitamin D25(OH)D was measured using the Elecsys® Vitamin D total test. A total of 226 patients with biopsy-positive sarcoidosis were analyzed. The average median value of serum vitamin D was 9.47 mg/L, suggesting severe deficiency. Statistically significant correlation was found in patients with chronic disease and low levels of serum vitamin 25(OH)D (Chi-Square=6.044; df=2; p=0.014). The patient group with vitamin D serum levels higher than 20 mg/L showed higher levels of the mean forced vi tal capacity (FVC) by 380 mL, and forced expiratory volume in one second (FEV1) by 220 mL, when compared to the patient group with lower serum vitamin D. A statistically significant role was established for serum vitamin 25(OH)D levels as the predictor of fatigue (R2=0.878; p=0.038 (b=0.216)) and depression in patients with sarcoidosis (R2=0.80; p=0.000 (b=0.391)). The insufficiency of 25(OH)D seems to be an important factor in predicting the course of chronic disease, significant lung function impairments and cognitive failures such as fatigue and depression. The fact that the majo rity of the analyzed sarcoidosis patients had totally deficient serum 25(OH)D levels made this finding even more notable.

AbstractThe objective of this study was to examine the cross-sectional relationship between homeostasis model assessment for insulin resistance (HOMA-IR) and serum 25-hydroxyvitamin D (25-OHD) level in Chinese children and adolescents.Anthropometric indices, lipid metabolic profile, and serum levels of glucose, insulin and 25-OHD were determined among 278 healthy prepubertal and pubertal, normal and overweight/obese children and adolescents aged 8–18 years between March 2014 and February 2015.HOMA-IR was significantly different across vitamin D statuses (p<0.001), even after adjusting for body mass index (BMI) (p=0.035) and waist-to-height ratio (p=0.044); the difference was not significant between the vitamin D deficient and insufficient groups (p=0.120). HOMA-IR negatively correlated with serum 25-OHD level for all subjects (ROur findings supported that lower vitamin D status is strongly associated with worse HOMA-IR.

ABSTRACT Objective: Vitamin D has taken center stage in research and treatment of multiple sclerosis (MS). The objective of the present study was to assess the serum vitamin D levels of a large population of patients with MS and controls living in a restricted tropical area. Methods: Data from 535 patients with MS and 350 control subjects were obtained from 14 cities around the Tropic of Capricorn. Results: The mean serum 25-OH vitamin D level was 26.07 ± 10.27 ng/mL for the control subjects, and 28.03 ± 12.19 ng/mL for patients with MS. No correlation was observed between vitamin D levels and the disability of patients over the disease duration. Conclusion: At least for the region around the Tropic of Capricorn, serum levels of vitamin D typically are within the range of 20 to 30 ng/mL for controls and patients with MS.

Abstract Background There is growing literature suggesting a link between vitamin D and asthma lung function, but the results from systematic reviews are conflicting. We conducted this meta-analysis to investigate the relation between serum vitamin D and lung function in asthma patients. Methods Major databases, including OVID, MEDLINE, Web of Science and PUBMED, were searched until 10th October 2018. All published observational studies related to vitamin D and asthma were extracted. All meta-analyses were performed using Review Manager 5.3.5. Results This quantitative synthesis found that asthma patients with low vitamin D levels had lower forced expiratory volume In 1 s (FEV1) (mean difference (MD) = − 0.1, 95% CI = − 0.11 to − 0.08,p < 0.01;I2 = 49%, p = 0.12) and FEV1% (MD = − 10.02, 95% CI = − 11 to − 9.04, p < 0.01; I2 = 0%, p = 0.82) than those with sufficient vitamin D levels. A positive relation was found between vitamin D and FEV1 (r = 0.12, 95% CI = 0.04 to 0.2, p = 0.003; I2 = 59%,p = 0.01), FEV1% (r = 0.19, 95% CI = 0.13 to 0.26, p < 0.001; I2 = 42%, p = 0.11), forced vital capacity (FVC) (r = 0.17, 95% CI = 0.00 to 0.34, p = 0.05; I2 = 60%, p = 0.04), FEV1/FVC (r = 0.4, 95% CI = 0.3 to 0.51, p < 0.001; I2 = 48%, p = 0.07), and the asthma control test (ACT) (r = 0.33, 95% CI = 0.2 to 0.47, p < 0.001; I2 = 0%, p = 0.7). Subgroup analysis indicated that the positive correlation between vitamin D and lung function remained significant in both children and adults. Conclusions Our meta-analysis suggested that serum vitamin D levels may be positively correlated with lung function in asthma patients. Future comprehensive studies are required to confirm these relations and to elucidate potential mechanisms.

ABSTRACT Allergic rhinitis is a common condition affecting 5 to 40% of general population and its prevalence is increasing. It is a chronic condition characterized by inflammation of nasal mucosa. As per recent studies, there is an association between serum vitamin D levels and allergic rhinitis status. Vitamin D has major role in the regulation of calcium metabolism. In addition to this, it also has a number of immunological effects and takes part in immunomodulation, which can significantly affect the outcome of allergic responses like in allergic rhinitis. Aims and objectives To establish the correlation between vitamin D3 serum levels and allergic rhinitis. Materials and methods Vitamin D levels were assessed in 23 patients with allergic rhinitis diagnosed clinically by allergic rhinitis and its impact on asthma 2008 criteria and results were compared with vitamin D status in the normal population of same region. Results The levels of serum vitamin D levels were significantly low in the patients of allergic rhinitis. Conclusion Measuring of serum levels of vitamin D could be considered in the routine assessment of patients with allergic rhinitis.

The aim of this study was to evaluate the effects of Plantago major liquid extract on serum antioxidant vitamin and mineral concentrations of broiler. The experiment consisted of the control and 2 treatment groups, composed of 28 Ross 308 broiler chicks (Total, 84). A basal (control) diet was formulated. P. Major was added to the control diet as following: PM1 (5 g/kg feed), PM2 (10 g/kg feed). The chicks were feed for 42 days ad libitum. The serum micronutrients (Retinol, á-tocopherol, vitamin D, calcium, magnesium, iron, manganese, and zinc) levels were determined. The retinol, á-tocopherol, Fe, Mg, Mn levels were not affected, and the Zn levels decreased in the PM1 and PM2. The supplementation of P. major has affected the serum vitamin D and Zn levels for this study, and should be analyzed for the alterations on the metabolism in subsequent studies.

Aim of study. To study the total level of 25-hydroxyvitamin D in children with SARS-CoV-2 infection (COVID-19). Material and мethods. A total of 82 children aged 0-17 diagnosed with SARS-CoV-2 infection were enrolled. Depending on the severity of clinical symptoms, all children were divided into three groups according to the COVID-19 severity: asymptomatic, mild and moderate. The serum level of vitamin D in all patients was tested via the immunochemical method. Results. It was found that children with SARS-CoV-2 infection had lower serum level of vitamin D (29.92 [22.22; 28.07] ng/ml) as compared with the control group (36.43 [32.05; 44.08] ng/ml; p<0.001). A total of 90% of the children with SARS-CoV-2 infection were diagnosed with insufficiency or deficiency of vitamin D (<30 ng/ml). Only 10 % of the patients had normal levels of vitamin D. The insufficiency of vitamin D was found more often amongst children aged 0-11 and deficiency of total 25-hydroxyvitamin D was more common for children aged 12-17. The difference in serum levels of vitamin D depending on the severity of SARS-CoV-2 infection was not found. Male children with SARS-CoV-2 infection showed lower levels of vitamin D (p=0.013). Conclusion. A total of 90 % of the children with SARS-CoV-2 infection had insufficiency or deficiency of vitamin D regardless of the severity of clinical symptoms.

Introduction: Coronavirus disease 2019 (COVID-19) from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is one of the most important epidemiological events in the past 100 years has become, the consequences for public health and economic systems around the world. Vitamin D is an important micronutrient that has been reported to improve immunity and protect against respiratory diseases. In this study, we intend to review articles that examine the relationship between COVID-19 and vitamin D. Methods: This is a review that uses articles from studies published in 2020 on the relationship between COVID-19 and vitamin D in databases such as; Web of Science, Science Direct, SID, Magiran, Google Scholar and PubMed. Keywords used included; serum levels of 25-hydroxyvitamin D, vitamin D, COVID-19, SARS-COV-2 and coronavirus 2. With this search, 32 articles were finally selected for this purpose and their results were reviewed Results: Of the 32 studies reviewed, only three showed no association between vitamin D levels in the blood and COVID-19 disease. Other studies had a relationship between the severity of the disease, mortality rate and length of hospital stay, in different age, gender and location groups. Conclusion: It seems that the level of vitamin D in the blood has a potential effect on COVID-19 disease. Checking the serum vitamin D levels and supplementation in people with hypovitaminosis D can be a good solution to reduce the complications and problems caused by COVID-19.

SUMMARY OBJECTIVE To investigate the association between low serum vitamin D levels and peripheral arterial disease (PAD). METHODS A cross-sectional study with a consecutive sample of 133 individuals from Caxias do Sul, Brasil. We considered PAD patients those with an ankle-brachial index (ABI) ≤ 0.90 or with arterial revascularization. Vitamin D serum level was categorized as sufficient (≥30 ng/mL), insufficient (>20 to 29 ng/mL), and deficient (<20 ng/mL). Prevalence ratios (RP) were calculated through Poisson regression. RESULTS The prevalence of PAD was 50.7% (95% CI 42-59). After adjustment for potential PAD risk factors, RP were 1.08 (95% CI 0.66-1.76) for insufficient serum level and 1.57 (95% CI 0.96-2.57) for deficient vitamin D serum level; (p for trend = 0.020). CONCLUSION Vitamin D serum levels showed an inverse and significant dose-response relationship with PAD.

Coronavirus Disease 2019 (COVID-19) causes immune system dysregulation and an exaggerated systemic inflammatory response. Vitamin D acts as an immunomodulator that enhances the immunity defense. Low levels of vitamin D affect the severity of COVID-19 infection. This study aims to determine vitamin D levels in hospitalized and non-hospitalized COVID-19 patients. A case-control study was conducted involving 62 COVID-19 patients, equally divided into hospitalized and non-hospitalized groups at RSUP dr. M. Djamil, Padang from February to September 2020. Serum vitamin D levels were measured using the Chemiluminescent Microparticle Immunoassay. Vitamin D deficiency was defined as a level less than 20 ng/mL. The hospitalized group consisted of moderate to critical COVID-19 patients, whereas the non-hospitalized group consisted of the asymptomatic and mild COVID-19 patients according to the Indonesian Ministry of Health Guidelines. All data were analyzed using a T-test and Chi-square with a significant p-value of 0.05. The results showed that most subjects were women between 21–60 years. The mean level of vitamin D (ng/mL) in the hospitalized group was lower than in the non-hospitalized group (15.5 ± 7.72 vs. 19.2 ± 14.30; 95% CI -9.509–2.167; p=0.213). Vitamin D deficiency affected hospitalized group more than the non-hospitalized group, but not statistically significant (71% vs. 64.5%, p=0.566). It indicated the role of vitamin D in preventing immune system hyperactivation causing COVID-19 cytokine storm. This study concluded no difference in vitamin D levels among the study groups. Nevertheless, further research on vitamin D is needed to determine its role and benefits against COVID-19 infection.

BACKGROUND: Serum levels of 25-hydroxyvitamin D (25(OH)D), prostaglandin E2 (PGE2), and cyclooxygenase 2 (COX2) expression differ between breast cancer stages. Since, previous studies showed mixed results, in this study, we aimed to analyze vitamin D levels related to breast cancer stages and serum levels of COX2 and PGE2 in Indonesia.METHODS: This was a cross sectional study involving 75 breast cancer patients. Subjects were divided into 3 groups, namely operable early stage (K1), locally advanced stage (K2), and advanced stage (K3). Venous blood samples were taken from each subject, then were analyzed for the 25(OH)D, COX2, and PGE2 serum levels by enzyme-linked immunosorbent assay (ELISA) method.RESULTS: There were significant differences in 25(OH)D among groups (p=0.012); between K1 and K2 (p=0.009) and between K1 and K3 (p=0.023). However, there was no significant difference in serum COX2 level (p=0.328). There were significant differences of PGE2 among groups (p=0.002); between K1 and K2 (p=0.036) and between K1 and K3 (p=0.001). Correlation test showed that there were differences between 25(OH)D serum levels and PGE2 serum level (r=0.306, p=0.008) and also between 25(OH)D serum level and breast cancer stage (r=-0.229; p=0.048).CONCLUSION: There were differences in serum Vitamin D and PGE2 levels at various stages of breast cancer. Serum 25(OH)D levels had weak correlation with breast cancer stage and PGE2 serum level. Serum vitamin D level in advanced breast cancer were lower than early stage breast cancer and indicate a poor prognosis.KEYWORDS: breast cancer, 25-hydroxyvitamin D, cyclooxygenase 2, prostaglandin E2
