Background: Pediatric asthma is a prevalent disease and has a significant immunologic and inflammatory nature. In recent years, the role of vitamin D3 in immunologic processes has been studied, and many aspects of this role have been clarified in some human diseases. Objective: The aim of this study was to evaluate the relationship among the vitamin D3 status, Pediatric Asthma Severity Score (PASS), and inflammatory indicators of pediatric asthma. Methods: Among all of the pediatric patients with asthma and with asthma exacerbation, 100 patients were randomly enrolled in the study and subdivided into three groups according to serum levels of 25-OH vitamin D3. The control group consisted of 100 sex- and age-matched healthy subjects. Asthma exacerbation severity was evaluated based on the PASS before starting the medical care. The count of the white blood cells, eosinophil count, and serum levels of total immunoglobulin E (IgE) plus 25-OH vitamin D3 were measured in all the subjects. The obtained data were then compared via proper statistical tests. A p value of <0.05 was considered as statistically significant. Results: The median level of serum IgE was increased in patients with vitamin D3 deficiency compared with other groups. There was a significant inverse correlation between serum levels of 25-OH vitamin D3 and IgE in pediatric patients with asthma (r = ‐0.483, p = 0.001). Furthermore, the serum levels of 25-OH vitamin D3 also significantly inversely correlated with the PASS (r = ‐0.285, p = 0.004). Conclusion: Vitamin D3 deficiency is associated with exacerbation severity and serum IgE levels in patients with pediatric asthma; hence, it can have an important role in pediatric asthma pathogenesis, possibly through IgE.

Background: The prevalence of vitamin D deficiency is increasing due to changes in lifestyle and dietary habits. The aim of this study was to compare the serum levels of 25-hydroxy vitamin D between patients with bronchial asthma and the healthy control group. Patients and Methods: In this case-control study, 45 patients with asthma and 45 healthy subjects were enrolled and the level of serum 25 (OH) vitamin D was measured in both groups. In addition, a welltrained observer assessed airway reversibility, peak flowmetry and spirometry in the participants. The data were statistically analyzed using t test, one-way analysis of variance (ANOVA), and chi-square test with Stata software (version 11). Results: The mean age (±SD) of participants were 49.06 ±16.43 and 46.13 ±16.10 years in case and control groups, respectively (P=.394). The prevalence of vitamin D deficiency was high in both groups (69% in case and 65.5% in control groups). The mean (±SD) serum 25 (OH) vitamin D was 16.24 (±14.98) ng/ml in case group and 17.70 (±16.07) ng/mL in control group (P=.657). We found a positive correlation between the levels of vitamin D and the amount of FEV1 (r=0.2). Conclusions: According to the present study, the mean serum levels of vitamin D differences were not statistically significant between asthmatic patients and control group. However, the results of this study showed a positive relationship between forced expiratory volumes in first second (FEV1) and vitamin D levels

Background. We assessed vitamin D intakes and serum 25(OH) vitamin D levels in pediatric asthma patients on moderate-to-high dose inhaled steroids and compared them to published findings of healthy children in our city.Methods. Parents and/or patients were interviewed to estimate the children’s vitamin D intakes from foods and supplements (using an adapted validated food frequency questionnaire) and asthma duration and management. Vitamin D status: serum 25-hyroxy vitamin D (25(OH)D) was obtained from the medical records.Results. Vitamin D intakes from food and supplements of the asthma patients (n=20, 742 ± 185 IU/day) were significantly higher compared to healthy Canadian children (n=1442, 229 ± 121 IU/day). Despite higher vitamin D intakes, the children had nonsignificantly lower serum 25(OH) vitamin D levels compared to the comparison group. Serum 25(OH)D levels increased by 3.6 nmol/L with each 100 IU of vitamin D intake (95% Confidence interval = 2.0–4.0,R2= 0.931, andp=0.001).Conclusion. Since adequate vitamin D status in asthma patients is necessary to support bone mineral accretion, it is important to achieve adequate vitamin D status by checking serum 25(OH)D status and supplement accordingly.

Cardiovascular diseases represent important complications in rheumatoid arthritis (RA) patients, generated by an accelerated atherosclerosis. The aim of this study is represented by the assessment of the correlations between serum levels of vitamin D, disease activity, and endothelial dysfunction in patients with early RA. Material and Methods. The study was performed on a group of 35 patients with early RA and 35 healthy subjects matched for age and gender, as controls. In all studied subjects, the following were determined: inflammatory markers, insulin resistance, vitamin D levels, and endothelial dysfunction. Statistical analysis were performed using the Student’s t-test and the Pearson’s test. p values of less than 0.05 were considered statistically significant. Results. The group of patients with RA patients presented inflammation, low levels of vitamin D, elevated insulin resistance, and reduced flow-mediated vasodilation, statistically significant compared to the control group (p<0.00001). Significant inverse correlations between the levels of 25(OH) vitamin D and DAS28, respective insulin resistance, and significant positive correlation between 25(OH) vitamin D and endothelial function were demonstrated. Conclusion. In early RA patients with moderate and high disease activity, low serum levels of vitamin D were associated with disease activity, increased insulin resistance, and endothelial dysfunction.

AbstractPatients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.

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.

Introduction: Metabolic syndrome includes a range of disorders that increase the risk of cardiovascular disease and diabetes mellitus. In this study, we examined the serum level of vitamin D3 in diabetic individuals with metabolic syndrome compared with non-diabetic individuals without metabolic syndrome and the association of serum vitamin D3 levels with metabolic syndrome and atherogenic factor (LDL/HDL). Material and Methods: In a case-control study, we included 110 women with metabolic syndrome according to ATP III criteria and 127 healthy women as a control group. Serum concentration of total cholesterol, LDL-C, FBS, HDL-C and serum triglyceride determined by enzymatic method and colorimetric and, serum level 25-(OH) vitamin D determined by ELISA. Results: It was found that the two healthy and metabolic groups were significantly different in terms of total cholesterol levels, LDL and triglyceride levels, HDL, VLDL, FBS, atherogenic index (LDL/HDL) and vitamin D levels (p<0.05). All participants in the control group and the patient and the whole study population were divided into two categories of insufficient and sufficient based on their measured serum concentrations of 25-(OH) vitamin D. There was a significant difference between the group with insufficient levels of vitamin D in comparison with the group with sufficient levels of vitamin D in terms of total cholesterol, LDL and triglyceride levels, HDL, VLDL, FBS and atherogenic index (LDL/HDL) (p=0.000). Conclusion: The present results showed that there is a significant relationship between level 25-(OH) D and atherogenic index (LDL/HDL) and the incidence of metabolic syndrome.

Background: Acute respiratory tract infection are a major cause of global morbidity and mortality. Observational studies report consistent independent association between low serum concentration of 25-hydroxy-vitamin D and susceptibility to acute respiratory tract infection. This study was done to assess serum vitamin D level in children and correlation with respiratory tract infection.Methods: The present study was undertaken in department of paediatrics medicine, Patna Medical College and Hospital in patients attending out-patients department (OPD) as well as admitted in in-patients department (IPD). Assessment of serum 25(OH) Vitamin D was done by the enzyme immunoassay kit at Patna Medical College and Hospital.Results: The mean serum vitamin D level in cases was (20.52±5.64 ng/ml) where as in control group was (26.46±4.52 ng/ml) with a statically significant p value of <0.0001, hence cases are associated with vitamin D deficiency.Conclusions: The finding in this study showed significantly decreased mean serum vitamin D level in cases than that of control which implies that vitamin D deficiency predisposes to respiratory tract infection in children.

Even though vitamin D is widely acknowledged as having a potential immunomodulatory role in asthma, its exact beneficial mechanisms are yet to be clarified. An optimal serum 25-hydroxy-vitamin D (25-OH-VitD) level in pediatric asthma patients might not rely solely on the effect of dose-dependent vitamin D3 intake, but might also be influenced by factors related to insufficient asthma control. We aimed to survey the prevalence of serum 25-OH-VitD deficiency and analyze whether suboptimal levels were associated with asthma severity factors. The current cross-sectional study enrolled 131 pediatric asthma or asthma-suggestive recurrent wheezing patients, for whom serum 25-OH-VitD, IgE, and eosinophil count were assessed. The prevalence of suboptimal serum 25-OH-VitD was 58.8%. A suboptimal vitamin D status was associated with asthma exacerbation in the previous month (p = 0.02). Even under seasonal oral vitamin D3 supplementation, patients with a positive history of asthma attack in the previous four weeks presented significantly lower serum 25-OH-VitD concentrations, compared to their peers with no disease exacerbation. In conclusion, sequential measurements of serum 25-OH-VitD might prove useful for future studies evaluating the dynamic changes in vitamin D3 status in regard to asthma, especially in symptomatic patients.
