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.

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.

Abstract Children undergoing HSCT are at risk for vitamin D deficiency due to lack of sun exposure, the recommended use of sunscreen, dietary insufficiency, and the effects of medications such as glucocorticoids and calcineurin inhibitors. We assessed the prevalence of 25-hydroxyvitamin D (25-OH vitamin D) deficiency in pediatric post-HSCT patients in an outpatient oncology clinic during 4 weeks in May 2008. Patients found to have low 25-OH vitamin D levels were referred for dietary counseling and given supplementation or repletion as needed. 25-OH vitamin D and parathyroid hormone (PTH) levels were measured in 62 (88.6%) of 70 eligible patients. 83.8% of patients had a 25-OH vitamin D level less than the institutional lower limit of normal, 30 ng/mL. 29% of patients were 25-OH vitamin D insufficient with levels 20–29 ng/mL (range of 20–29). 54.8% of patients were 25-OH vitamin D deficient with levels &lt;20 ng/mL (range 5–19). The prevalence of insufficiency and deficiency was similar between male (87.8%; 57.6%) and female patients (57.6%; 55.2%).The mean duration of days following transplant was 532.6 days (median 251.5 days). The mean age at transplant was 3.7 years (median 3.5 years). 47% of patients were female. 75.8% were Caucasian. 90.3% received allogeneic transplants. The underlying diseases were as follows: ALL (27.4%), AML/MDS (24.2%), bone marrow failure (11.3%), nonmalignant hematologic diagnosis (8.1%), solid tumor (8.1%), immunodeficiency (6.5%), lymphoma (6.5%), and other diagnoses (8.1%). 8 patients regularly took either an over-the-counter multivitamin or vitamin D supplement and all 8 patients had 25-OH levels less than 30 ng/mL. There was a negative inverse correlation of (r= −0.3, p=0.029) between PTH and 25-OH vitamin D. There were no significant associations between 25-OH vitamin D level and any of the following: corticosteroid or calcineurin inhibitor use in the preceding year, time from transplant, age at transplant, current age, or graft-versus-host disease. 25-OH vitamin D insufficiency and deficiency are common following pediatric HSCT. We recommend vitamin D screening for all post-HSCT pediatric patients. Further investigation is needed to identify potential risk factors for vitamin D deficiency and the long-term effects of deficiency on bone health and development.

Background Long-term anticonvulsant therapy, especially with enzyme inducers, has been associated with low 25-hydroxyvitamin D [25(OH)D] levels and high prevalence of vitamin D deficiency. However, there have been inconsistent results in studies on the effect of long-term, non-enzyme inducer anticonvulsant use on vitamin D levels.Objective To compare 25(OH)D levels in epileptic children on long-term anticonvulsant therapy and non-epileptic children. We also assessed for factors potentially associated with vitamin D deficiency/insufficiency in epileptic children.Methods This cross-sectional study was conducted at two pediatric neurology outpatient clinics in Jakarta, from March to June 2013. Subjects in the case group were epileptic children, aged 6-11 years who had used valproic acid, carbamazepine, phenobarbital, phenytoin, or oxcarbazepine, as a single or combination therapy, for at least 1 year. Control subjects were non-epileptic, had not consumed anticonvulsants, and were matched for age and gender to the case group. All subjects’ 25(OH)D levels were measured by enzyme immunoassay.Results There were 31 epileptic children and 31 non-epileptic control children. Their mean age was 9.1 (SD 1.8) years. Most subjects in the case group were treated with valproic acid (25/31), administered as a monotherapy (21/31). The mean duration of anticonvulsant consumption was 41.9 (SD 20) months. The mean 25(OH)D level of the epileptic group was 41.1 (SD 16) ng/mL, lower than the control group with a mean difference of 9.7 (95%CI 1.6 to 17.9) ng/mL. No vitamin D deficiency was found in this study. The prevalence of vitamin D insufficiency in the epileptic group was higher than in the control group (12/31 vs. 4/31; P=0.020). No identified risk factors were associated with low 25(OH)D levels in epileptic children.Conclusion Vitamin D levels in epileptic children with long-term anticonvulsant therapy are lower than that of non-epileptic children, but none had vitamin D deficiency.

Aim: The aim of this study was to compare vitamin D levels between pregnant women with hyperemesis gravidarum before 12 weeks of gestation and healthy pregnant women at similar ages. Methods: Sixty pregnancies with hyperemesis gravidarum and 60 age compatible healthy pregnancies applied to our facility were included in the study. Demographic characteristics, maternal thyroid function tests and 25-Hydroxyvitamin D levels were evaluated. Student t test was used for the variables with normal distribution and Mann-Whitney U test was used to analyze the variables without normal distribution. Results: Only one pregnant woman had normal vitamin D levels (>30ng/ml), whereas 71 patients had deficiency (10-30 ng/ml), and 48 had severe deficiency (<10 ng/ml). The mean vitamin D level of the total 120 pregnancies was 11.9±5.00 ng/ml (9.92±3.67 ng/ml in case group, 13.88±5.38 ng/ml in control group). The mean value of vitamin D was found to be significantly lower in hyperemesis gravidarum. 45% (n=27) of the pregnant women had vitamin D deficiency, whereas 55% (n=33) of them had severe deficiency. Free T3 and T4 levels were significantly higher than the control group, and thyroid-stimulating hormone level was significantly lower. Conclusion: Vitamin D levels of pregnant women with hyperemesis gravidarum were significantly lower. Vitamin D deficiency should be considered in patients with hyperemesis gravidarum.

Background: Transient tachypnea of the newborn (TTN) is one of the most frequent causes of respiratory distress in neonates. A relationship has been shown between vitamin D deficiency and respiratory disorders in neonates. This research was carried out to evaluate the serum level of vitamin D in TTN newborns and their mothers compared to the control group. Methods: This case-control research was conducted during 2016-2019 in a general hospital affiliated with Mashhad University of Medical Sciences, Iran. Thirty-four infants with TTN and 82 neonates in the control group as well as their mothers were investigated. The levels of umbilical cord serum vitamin D in infants with TTN and also their mothers were compared to the control group. Results: The mean levels of serum vitamin D in infants with TTN and their mothers were 8.11 ± 4.32 and 12.6 ± 10.12 ng/mL, respectively (P<0.001), whereas they were 19.21 ± 12.71 and 25.96 ± 16.6 ng/mL in the newborns of the control group and their mothers, respectively (P<0.001). The mean differences (95% CI) of neonatal and maternal vitamin D level between the two groups were 11.10 (7.92–14.28) and 13.36 (7.90–18.08), respectively. In the TTN group, 100% of the infants had vitamin D levels less than 30 ng/mL (79.4% had severe, 17.6% had moderate and 2.9% showed mild deficiency). However, vitamin D levels lower than 30 ng/mL were observed in 76.4% of the neonates in the control group (28.8% had severe, 31.1% showed moderate and 16.3% had a mild deficiency) (P<0.001). Conclusion: The serum vitamin D levels of infants with TTN and their mothers were significantly lower than the control group. Therefore, TTN in infants may be reduced through the treatment of vitamin D deficiency in mothers.

Objective.To investigate 25-OH vitamin D concentrations in 2 independent systemic sclerosis (SSc) populations from France and Italy.Methods.We studied 156 consecutive SSc patients comparable for demographic characteristics: 90 from Northern France and 66 from Southern Italy. 25-OH vitamin D, intact parathyroid hormone, and serum total calcium and phosphorus were measured in all patients. Vitamin D concentrations < 30 ng/ml were considered insufficiency, while values < 10 ng/ml were classified as deficiency.Results.Vitamin D insufficiency and deficiency rates were very high and comparable between the 2 populations: 74/90 (82%) versus 57/66 (86%) for insufficiency and 29/90 (32%) versus 15/66 (23%) for deficiency, respectively, in the French and Italian patients. They were not influenced by vitamin D supplementation, which was not statistically different in the 2 groups. In the combined populations, a significant negative correlation was found between low vitamin D levels and European Disease Activity Score (p = 0.04, r = −0.17) and an even more significant correlation was found with acute-phase reactants (p = 0.004, r = −0.23 for erythrocyte sedimentation rate), and low levels of vitamin D were associated with the systolic pulmonary artery pressure (sPAP) estimated by echocardiography (p = 0.004). In multivariate analysis, vitamin D deficiency was associated with sPAP (p = 0.02).Conclusion.Vitamin D deficiency was very common in the 2 SSc populations, independent of geographic origin and vitamin D supplementation. This suggests that common vitamin D supplementation does not correct the deficiency in SSc patients, and that a higher dose is probably needed, especially in those with high inflammatory activity or severe disease.

Background: Vitamin D deficiency can play a role in cardiovascular conditions, such as coronary artery disease, heart failure and hypertension. Vitamin D deficiency can activate the renin-angiotensin-aldosterone system, which in turn affects the cardiovascular system. Thus, a relationship between vitamin D deficiency and thoracic aortic dilatation (TAD) and aneurysm could be postulated. In this study, we compared 25-OH vitamin D levels between TAD and control groups. Patients and methods: This study included 87 patients with TAD who were 40 - 70 years old. The control group consisted of 93 patients who were 40 - 70 years old and did not have TAD. A transthoracic echocardiography was performed on each patient. Along with routine tests, the 25-OH vitamin D and parathormone (PTH) levels were analyzed. Results: No statistically significant difference was found between the two groups regarding their basic characteristics. The average PTH level of the TAD group was higher than that of the control group (94.87 ± 44.96 and 66.39 ± 30.58 pg/ml, respectively; p < 0.001). The average 25-OH vitamin D level of the TAD group was lower than that of the control group (11.89 ± 7.54 and 15.98 ± 4.98 ng/ml, respectively; p = 0.001). The initial conventional echocardiographic parameters of both groups were comparable. Logistic regression analysis revealed that the PTH and 25-OH vitamin D levels were independent predictors of TAD. Conclusions: Vitamin D deficiency was found as an independent factor associated with TAD.

Abstract Introduction: The survival of the patients with thalassemia has progressively improved with advances in therapy, however, increased survival allowed for several complications of disease. Metabolism of vitamin D affected in patients with thalassemia, due to accumulation of iron in the liver as the skin. The aim of this study is to compare vitamin D and parathyroid hormone (PTH) levels between patients with thalassemia and healthy control group. Methods: In pediatric hematology clinic, 33 patients (23 male, 10 female) with beta thalassemia major and 33 age-sex matched healthy people as a control group were included. Serum 25- OH Vitamin D levels were defined as normal >30 ng/ml, insufficiency between 20-30 ng/ml and deficiency < 20 ng/ml and PTH levels as normal between 10-65 pg/ml, decreased <10 pg/ml, and increased >65 pg/ml. Results: Mean age was 23.02+8.18 years old in patient group and 23+ 8.16 in control group. %33.3 of the patients had 25-OH vitamin D insufficiency and %30.3 of had 25-OH vitamin D deficiency. In different studies, the 25-OH vitamin D deficiency found between %12-90, and insufficiency between % 24.7-69.8 of the thalassemic patients. %81.8 of the patients had normal PTH levels, %18.2 decreased and none of the patients were found increased. In literature, there were confluent results about PTH levels in thalassemic patients, some of the studies showed hypoparathyroidism, and some of hyperparathyroidism or normal levels of PTH (Vogiatzi Br J Haematol 2009, Moulas Acta Paediatrica 1997, Merchant Indian J Pediatr 2011). In our study we couldn't show hyperparathyroidism in patient group. Also we found parathyroid hormone levels were significantly lower (p<0.001), while 25-OH vitamin D levels were significantly higher (p<0.05), in patients with thalassemia than in control group. This result was interestingly showed that, normal population in our country may be low levels of vitamin D. So we need more studies about PTH and vitamin D levels of healthy people, not only thalassemic patients in our country. Disclosures No relevant conflicts of interest to declare.

Background: Osteoporosis is a serious, worldwide, and growing health problem; WHO has estimated the 30% of all women, older than 50 years (post-menopausal) has osteoporosis. Osteoporosis is a skeletal disorder characterized by compromised bone strength predisposing a person to an increased risk of fracture. Bone strength reflects the integration of two main features: bone density and bone quality.Methods: After clinical examination, patients were subjected to lab and radiological investigation as under: complete hemogram with ESR, serum calcium, phosphate, alkaline phosphatase, parathyroid hormone, 25 (OH) vitamin-D, KFT, LFT, DEXA scan. From above data, vitamin-D levels DEXA scan (t-score) was collected and statistically analysed.Results: 53 radiologically established cases by DEXA score (spine) of osteoporosis/osteopenia and 50 persons in control group of the age and sex match with normal DEXA score, presenting to OPD of central institute of orthopaedics, VMMC and Safdarjung Hospital were selected. The mean vitamin D3 level in cases was 19.37ng/ml with standard deviation of 10.2. Range of serum vitamin D3 levels in cases was from 7 to 51.2. Whereas mean vitamin D3 level in control group was 25.92 ng/ml with standard deviation of 7.24. Range of serum vitamin D3 levels in controls was from 10 to 35.5. The mean vitamin D levels of cases and control was 19.735±10.2 and 25.92±7.2 ng/ml respectively, these values were compared by using student t test and results were found to be statistically significant (P= 0.0001). The mean T score in spine cases was -2.59 with standard deviation of 0.92. Range of T score in cases was from -5.1 to -1. Whereas, mean T score in control group was -0.26 with standard deviation of 0.68. Range of T score in controls was from -0.9 to 1.4. The mean T score spine of cases and controls was -2.59±0.92 and -0.264±0.68 respectively, these values were compared by using student t test and results were found to be statistically significant (P = 0.0001).Conclusions: Study recommend that, vitamin D supplementation should be given to patients with osteopenia/osteoporosis. Further prospective studies to firmly establish the relationship between vitamin D and osteoporosis as well as evaluation of vitamin D supplementation in osteoporosis are needed.

Background: The range of normal closure time of the anterior fontanelle (AF) is generally regarded to be 4 to 26 months. The objectives of this study was to find out the prevalence of subclinical vitamin D deficiency and hypothyroidism in children aged 18-36 months with open AF.Methods: This is a hospital based, cross-sectional study done over a period of 24 months, in which thyroid function tests and 25-hydroxy-vitamin D levels were done for healthy children aged 18-36 months with open AF; the latter was also done for equal numbers (n=30) of age and sex matched children with closed AF for control values. The mean vitamin D levels and proportion of children of various categories based on vitamin D levels among both the groups were compared.Results: Open AF was seen in 37 children. Seven of them had obvious causes of delayed AF closure and were excluded. In the remaining 30 children, none of the children had abnormal thyroid function tests. 23.3% of the study group had low vitamin D levels; but, the levels were low even in 37% of control group. The mean vitamin D level of the study group (39.05±17.11 ng/ml) was similar to the control group (37.3±14.74 ng/ml).Conclusions: Neither subclinical vitamin D deficiency nor subclinical hypothyroidism accounted for delayed AF closure in this study.
