The Difference

Background: Asthma is a chronic immunological disorder of the lungs. Vitamin D has several effects on the innate and adaptive immune systems. Little is known about vitamin D level and its impact on severity of asthma in children. This study aimed to determine vitamin D levels in asthmatics versus control children; studying the relation if any between these levels and asthma severity.Methods: This cross-sectional study was conducted on 60 asthmatic children and 20 apparently healthy children as controls. Asthma patients were divided into 3 groups (mild, moderate, severe; 20 each). Asthma severity was based on GINA criteria. Vitamin D level was measured to all study group.Results: The difference between the mean values of vitamin D level in control and asthmatic patients was statistically significant (p<0.001). This difference between control group and each asthma subgroup and between asthma subgroups versus each other were statistically significant being highest in control and lowest in patients with severe asthma (p<0.001). Differences in vitamin D status in control and all asthmatic patients were statistically significant (p<0.001). The difference between control group and each asthma subgroup according to vitamin D status were statistically significant (p<0.001). Concerning asthma subgroups the difference in vitamin D status between severe versus mild and moderate asthma were statistically significant (p<0.001), while between mild and moderate asthma it was not.Conclusions: Significantly lower vitamin D level in asthmatic children compared to controls and a differential decrease in vitamin D levels in asthmatic children being lowest in severe asthma was confirmed.

INTRODUCTION: We aimed to compare the mean platelet volume (MPV) and plateletcrit (PCT) and vitamin-mineral levels in pediatric celiac disease patients with the healthy control group and to compare the results with the literature. METHODS: In this study, clinical and laboratory data of 80 pediatric patients diagnosed with celiac disease (CD) between July 2017 and December 2018 and 42 healthy children in the same age group were retrospectively analyzed. RESULTS: There was no significant difference between the groups in terms of age and gender (p=0.383, and p=0.462, respectively). The frequency of anemia, folate, iron and vitamin D deficiencies was higher in celiac patients compared to the control group (p=0.001, p=0.027, p<0.001, and p<0.001, respectively). When the patients were evaluated according to their complete blood count and vitamin-mineral levels; hemoglobin (Hb), mean corpuscular volume (MCV), ferritin and vitamin D levels were found to be significantly lower in the CD group compared to the control group (p<0.001, p=0.026, p<0.00, and p=0.001, respectively). Platelet (PLT), PCT, MPV levels were found to be significantly higher in the CD group compared to the control group (p=0.010, p<0.001, and p<0.001, respectively). We found a weakly negative correlation between the vitamin D levels and the degree of the Marsh classification (r: -0.273, and p=0.023). DISCUSSION AND CONCLUSION: Our study have shown that MPV, PCT values are higher and Hb, folate, iron and vitamin D levels are lower in patients with CD compared to healthy controls. We recommend investigating other nutrient deficiencies besides iron deficiency, especially in treatment-resistant anemias. We think that the correlation between vitamin D levels and the degree of histological damage should be elucidated with larger-scale and more comprehensive studies.

Vitamin D status may be important for stress resilience. This study investigated the effects of vitamin D supplements during winter on biological markers of stress resilience such as psychophysiological activity, serotonin, and cortisol in a placebo-controlled, randomized clinical trial. Eighty-six participants were randomly assigned to the Intervention (vitamin D) or Control (placebo) groups. Before and after the intervention participants were exposed to an experimental stress procedure. Psychophysiological activity was measured during three main conditions: baseline, stress, and recovery. Fasting blood samples were taken in the morning and saliva samples were collected at seven different time points across 24 h. Prior to intervention both groups had normal/sufficient vitamin D levels. Both groups showed a normal pattern of psychophysiological responses to the experimental stress procedure (i.e., increased psychophysiological responses from resting baseline to stress-condition, and decreased psychophysiological responses from stress-condition to recovery; all p < 0.009). Post-intervention, the Intervention group showed increased vitamin D levels (p < 0.001) and normal psychophysiological responses to the experimental stress procedure (p < 0.001). Importantly, the Control group demonstrated a classic nadir in vitamin D status post-intervention (spring) (p < 0.001) and did not show normal psychophysiological responses. Thus, physiologically the Control group showed a sustained stress response. No significant effects of vitamin D were found on serotonin and cortisol.

e20000 Background: There is increasing interest in the possible association between cancer incidence and vitamin D through its role as a regulator of cell growth and differentiation. Although there are several studies related cancer risk and prognosis of cancer, related vit D levels in adult patients there are only few recent studies in pediatric patients. Methods: Between 2010 and 2011, D Vit levels of 45 patients (25 boys, 20 girls; age range: 6 months-17 years, median: 11 years) have been compared to D Vit levels of 22 healthy children with similar age group. Patient groups were leukemias, lymphomas, bone tumors, retinoblastoma (RB), and other tumors. Kruskal-Wallis and Spearman nonparametric correlations test of SPSS has been used for statistics. Results: Although there was no statistically significant difference for vit D levels between control group (range: 7.2-22.8; median: 14.75 ng/ml) and patients (range: 5.5-40.2; median: 16.0 ng/ml),difference between patients groups were significant (Table). Patients with RB have statistically lower level of Vit D than leukemia (p:0.016) and lymphoma groups ( p: 0.047). “Other tumors group” has lower vit D levels than leukemia group (p: 0.024). Since RB and other tumors group have younger age than other patients, Spearsman’s nonparametric correlation has been performed to exclude age effect on the results and no statistically significant correlation between D vit levels and age (p: 0.779) was found, although there was an inverse correlation between age and vit D levels in patient group (p: 0.03). Conclusions: According to our preliminary results, most of the patients and healthy children have low level of Vit D. Especially patients with RB have statistically significant lower level of Vit D than other malignancies which can be subject to future studies for confirmation of our results. In addition, etiologic studies related RB may have a new area. [Table: see text]

Asthma is a chronic disease that affects the airways in the lungs and is common in many countries. Studies have shown that vitamin D levels are associated with the onset and exacerbation of asthma symptoms. Given the role of vitamin D in regulating immune responses and the importance of the two major cytokines IL-4 (an inflammatory cytokine) and IL-10 (an anti-inflammatory cytokine) in immunological processes, in this study, the relationship between vitamin D intake and the level of expression of these ILs in asthmatic mice was investigated. In the case-control study performed in three groups of mice, 10 experimental asthma mice, 10 asthmatic vitamin D-treated mice, and 10 healthy mice as the control group were studied. For analyses, after RNA extraction and cDNA synthesis, the expression level of two IL-4 and IL-10 genes was evaluated by real-time PCR. Finally, the results were analyzed by SPSS software. The results showed that in the control group, the expression level of IL-4 and IL-10 genes was 0.01 and 0.02, respectively. Accordingly, the expression level of the IL-4 gene in asthmatic mice and asthmatic mice treated with vitamin D was 0.6 and 0.2, respectively, while the expression level of the IL-10 in these groups was 1.2 and 2.8, respectively, which showed significant changes (p-value < 0.05) in treated mice compared to the asthmatic mice without treatment. Based on results, in asthmatic mice treated with vitamin D, a significant increase in IL-10 expression was observed (1.2 to 2.8), while IL-4 expression was decreased from 0.6 to 0.2. It appears that vitamin D supplementation in asthmatic patients by affecting T-cell maturation and increasing anti-inflammatory IL-10 and suppressing IL-4 may play a role in reducing the symptoms of asthma.

Objective This study aimed to investigate the relationship between autism spectrum disorder (ASD) and vitamin D levels in children and adolescents. Methods We measured serum 25-hydroxyvitamin D (25-OHD) levels in 1529 patients with ASD aged 3 to 18 years, without any additional chronic diseases. Levels of 25-OHD were compared according to sex, age (<11 or ≥11 years), and birth season. Additionally, laboratory parameters (calcium, phosphorus, alkaline phosphatase, and 25-OHD) of 100 selected patients with ASD were compared with those of the healthy control group. Results Vitamin D deficiency or insufficiency was found in approximately 95% of all patients. Levels of 25-OHD in adolescent patients with ASD aged 11 to 18 years were significantly lower than those in patients aged younger than 11 years. In the 100 selected patients with ASD, mean serum 25-OHD levels were significantly lower and alkaline phosphatase levels were higher compared with those in healthy children. Conclusion Our study suggests a relationship between vitamin D and ASD in children. Monitoring vitamin D levels is crucial in autistic children, especially adolescents, to take protective measures and treat this condition early.

AIM: To determine the vitamin D levels in vernal keratoconjunctivitis (VKC) patients in Indian population. METHODS: A total of 30 non-atopic healthy children and 30 children having VKC were included in the study. The serum vitamin D levels and the time spent outside was compared between the two groups (P<0.05). RESULTS: The mean serum vitamin D level in the VKC group was significantly lower (mean 19.17±10.76 ng/mL) compared to the control group (mean 31.19±9.09 ng/mL) (P=0.0003). The vitamin D levels were found to be deficient (10-20 ng/mL) in 43.33%, whereas severe deficiency (<10 ng/mL) was found in 20% of the VKC patients. The deficiency of vitamin D correlated with the level of severity of VKC (P<0.02). The time spent outside in the VKC group was 1.07±0.76h, whereas in the healthy subjects it was 2.08±0.72h (P<0.0001), and it showed a significant correlation with the serum 25 (OH) D3 levels (r=0.478, P<0.001). CONCLUSION: The study shows that children with VKC had a significantly lower serum vitamin D levels as compared to the healthy children which correlated with time spent outside. The severity of VKC also correlated with the severity of vitamin D deficiency which suggests that vitamin D plays an important role in maintaining ocular surface health.

Vision integrates all the senses and plays a fundamental role in the acquisition of different skills and the general development of a child. Recently, refractive errors and visual impairment have become serious health problems among children. Background and Objectives: The aim of this study was to identify the prevalence of refractive errors and visual impairment in children with disabilities. Moreover, this study aimed to explore the risk factors for visual impairment in children with respect to vitamin D levels, parental smoking, and the use of spectacles. Materials and Methods: We retrospectively analyzed 161 children aged 5–16 years old, divided into two groups: a group of 80 children with disabilities and a control group consisting of 81 clinically healthy children. All the children underwent refraction measurements, visual acuity testing, and plasmatic vitamin D level dosing, measured in ng/mL. Results: Refractive errors and visual impairment were found to have a higher prevalence in the group of children with disabilities than in the control group. Moreover, the plasma level of vitamin D was lower in the group of children with special health needs. Conclusions: Given the present results, children with disabilities should undergo special eye examinations as soon as possible to ensure the quality of their socio-academic lives.

Background: Vitamin D deficiency is common among children and adolescents and can be affected by several factors such as puberty and obesity. Objective: The aim of this study was to evaluate vitamin D status in children and adolescents and to analyse the influence of puberty and obesity on its level. Method: A cross-sectional study was carried-out, in which clinical and biochemical data were gathered from 384 healthy children and adolescents between May 2019 to May 2020. Results: 220 females and 164 males were enrolled (aged 7-16 years; mean ± SD: 11 ± 2.5). Vitamin D deficiency was found in 49% of the total cases and was significantly more prevalent in females than males (33.1% in female; 15.9% in male, P < .001). Mean vitamin D level was lower in obese children compared with non-obese ( P < .001). Non-obese group had significantly higher levels of vitamin D in Tanner stage IV of puberty than obese individuals (20.1 ± 17.0 vs 5.4 ± 2.0) ( P = .03). Vitamin D levels were significantly lower in females than males only in Tanner stage II (12.3 ± 9.0 vs 19.6 ± 16.6) ( P = .005). The lowest level of Vitamin D was in Tanner stage Ⅳ-Ⅴ in boys and in Tanner stage Ⅱ-Ⅲ in girls ( P < .001). Conclusion: Puberty is an additional risk factor for vitamin D deficiency especially in girls and obese children. This increased risk, together with the fact that most important time for building a proper skeleton is during childhood and adolescent, makes it essential to monitor vitamin D in these age groups.

Abstract Background Community-acquired pneumonia is a major cause of death among children. Inadequate nutrition disrupts the immune system and increases the susceptibility to infections. We aimed to evaluate the association between vitamin D, serum zinc, and iron, and pneumonia. A case-control study was conducted at the outpatient clinic and emergency room of Children’s Hospital. Thirty-one patients with community-acquired pneumonia and 36 healthy children (control group) underwent serum sampling for vitamin D, zinc, and iron. Results Most patients had mild form (n = 17, 54.8%). All patients survived and were discharged. The serum iron level showed a non-significant difference between pneumonia and control groups (p ˃ 0.05). TIBC, vitamin D, and serum zinc were significantly lower in the patient group than the control group (P value = 0.04, < 0.001, and 0.03, respectively). Vitamin D deficiency was highly associated with the severity of pneumonia (P value = 0.008). Conclusion Adequate serum zinc and vitamin D levels may be protective against infection with community-acquired pneumonia in children aged from 2 months to 5 years old, but not iron.

Objective Research is limited regarding biochemical markers of bone metabolism among children with cow’s milk protein allergy (CMPA). We aimed to determine differences in vitamin D and bone metabolism markers between infants with CMPA and healthy infants and explore relationships between these in a cross-sectional study. Methods In total, we included 41 children diagnosed with CMPA and under systematic medical and nutritional care at our center, and 50 healthy children as a control group. We reviewed demographic and clinical characteristics and measured serum biomarkers. Results We found that serum 25-hydroxyvitamin D (25(OH)D) levels among infants in the CMPA group were significantly lower than those in the control group, and levels of bone-specific alkaline phosphatase (BALP), serum phosphorus, and serum calcitonin were reduced. Pearson correlation analysis showed that serum 25(OH)D concentrations in the CMPA group were negatively correlated with parathyroid hormone but not significantly correlated with calcitonin and BALP. Logistic regression showed that CMPA was a risk factor for vitamin D deficiency. Conclusions Our study indicated that CMPA was associated with disturbances in bone metabolism. Levels of vitamin D in children with CMPA were lower than those in healthy children. CMPA was a risk factor for vitamin D deficiency.
