Background: Recent epidemiological evidence points towards the potential association of vitamin D insufficiency with adverse metabolic risk and in the pathogenesis of cancer, cardiovascular diseases, type 2 diabetes and other diseases. Vitamin D exerts its action in a variety of cell types through vitamin D receptors. No reports are available in the literature regarding vitamin D and vitamin D receptor status in prediabetics. The present study was planned to compare serum 25-hydroxy vitamin D [25(OH)D] and vitamin D receptor (VDR) protein levels in prediabetic cases and normoglycemic controls. Methods: The present study was conducted in 80 persons who were divided into two groups, Study group (n= 40) comprised of diagnosed cases of prediabetes and control group (n=40) comprised of healthy normoglycemic controls. Serum 25-hydroxy vitamin D [25(OH)D] was analyzed by radioimmunoassay (RIA). Serum vitamin D receptor (VDR) protein was analyzed by sandwich enzyme immunoassay (ELISA). Results: Serum 25(OH) vitamin D levels were significantly decreased in prediabetic cases as compared to normoglycemic controls [p<0.001]. Serum Vitamin D receptor protein levels were highly significantly decreased in prediabetic cases as compared to normoglycemic controls [p<0.00]. Serum 25(OH)D levels showed a highly significant positive correlation with serum VDR levels in both the groups [p<0.001 at both levels]. Conclusion: The findings of the present study indicate that vitamin D and VDR can serve as a possible screening marker and target for modulation of the management and alleviating the progress and complications of diabetes.

Abstract Background Preeclampsia is a pregnancy-specific disorder that affects 3–5% of pregnant women worldwide and is one of the most frequently encountered medical complications of pregnancy. Recent research has pointed towards some role of vitamin D deficiency in pathogenesis of preeclampsia. Vitamin D deficiency in pregnant women and their children is a major health problem, with potential adverse consequences for overall health. Aim of the Study The aim of this study is to investigate the serum vitamin D levels in preeclampsia and healthy normotensive pregnant women. Patients and Methods This case control study was conducted at Ain Shams University Maternity Hospital from November 2017. The study included pregnant women 20-35years this study will be carried out on pregnant women recruited at pre labour room (preeclamptic group) and (non preeclamptic group) at Ain Shams University Maternity Hospital, 50 women in each group. Results All samples were screened by DRG® 25-OH Vitamin D (total) ELISA (EIA-5396) and it was found that mean 25 hydroxy vitamin D levels were lower in preeclamptic group than normotensive control group. Mean level of 25 hydroxy vitamin D between preeclamptic cases was 13.98 ±4.98 ng/ml and between normotensive controls was15.62± 3.51 ng/ml. Conclusion This study has shown no association between vitamin D deficiency and pre-eclampsia, supporting no role for vitamin D as a preventative agent against preeclampsia.

Psoriasis is an immuno-mediated chronic systemic disease involving cytokines of helper Th1 pathway. Vitamin D has an effect on keratinocyte proliferation, differentiation and immune modulation of immune system especially Th1 pathway, which is altered in psoriatic skin suggesting that Vitamin D may have a role in pathogenesis of psoriasis. To study correlation between psoriasis vulgaris and serum vitamin D. To evaluate serum vitamin D level in psoriasis cases and in control group and correlating vitamin D level with severity and duration of the psoriasis. 57 cases (&#62;15years of age) with psoriasis and 57 healthy subjects were recruited. Psoriasis was clinically diagnosed and severity evaluated by PASI scale. Vitamin D was analysed by enhanced chemilumine scence on vitrus Eci autoanalyzer of Orth clinical diagnostic. Vitamin D deficiency defined as &#60;20ng/ml, insufficiency 20-30ng/ml and sufficient 30-100ng/ml. Vitamin D deficiency in the study was 22.8% in patients and 14% in control group. Vitamin D insufficiency was found in 42.1% of cases and 19.3% of control. According to chi-square the p-value is 0.003 showing significant association. There was a tendency towards decrease in vitamin D level with increase in disease duration. There was negative correlation between vitamin D and PASI score. The study found a significant relationship between vitamin D and psoriasis. Further metanalysis involving larger study population will be required to establish whether vitamin D levels benefits patient with psoriasis vulgaris.

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.

Deep neck infection (DNI) refers to infections in spaces created by superficial and deep cervical fascia around the muscles and organs in the neck. Vitamin D is highly important for an effective immune system. Vitamin D receptors (VDR) have been identified in immune system cells, and particularly in T and B lymphocytes, macrophages, and dendritic cells. Vitamin D deficiency is thought to result in impaired immune response, decreased leukocyte chemotaxis, and an increased disposition to infection. The purpose of this study was to investigate whether vitamin D deficiency is an underlying occult factor in the development of DNI. Sixty-five patients aged 6 to 90, diagnosed with DNI, and 70 healthy age- and sex-compatible cases were included in the study. Serum levels of calcium, phosphorus, parathyroid hormone, and 25-hydroxy vitamin D (25(OH)D) were determined in each case. 25-hydroxy vitamin D levels above 20 ng/mL were regarded as normal, 12 to 20 ng/mL as insufficient, 5 to 12 ng/mL as deficient, and less than 5 ng/mL as severely deficient. Mean serum 25(OH)D levels were 10.4 (6.2) ng/mL in the patient group and 15.5 (6.4) ng/mL in the control group ( P < .01). This difference was statistically significant ( P < .01). Vitamin D was within normal limits in 9.2% (n = 6) of cases in the study group, insufficient in 29.2% (n = 19), deficient in 35.3% (n = 23), and severely deficient in 26.2% (n = 17). The equivalent values in the control group were 21.4% (n = 15), 48.5% (n = 34), 30% (n = 21), and 0% (n = 0). Serum 25(OH)D levels were significantly lower in patients with DNI compared to the healthy cases; 25(OH)D levels may be a factor in the development of DNI.

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.

Though vitamin D is important for bone health, little is known about the monitoring and management of vitamin D levels in patients with osteoporosis in clinical practice—a deficit this chart review initiative aimed to remedy. A total of 52 physicians completed profiles for 983 patients being treated for osteoporosis between November 2008 and April 2009. Information collected included demographics; fracture risk factors; availability and level of serum vitamin D measurements; and information on osteoporosis medications and calcium and vitamin D supplementation. Physicians also evaluated patients’ current regimens and detailed proposed changes, if applicable. Nearly 85% of patients were prescribed calcium and vitamin D supplements. Serum 25-hydroxy vitamin D levels were available for 73% of patients. Of these patients, approximately 50% had levels less than 80 nmol/L, which contrasts with the 37% thought to have “unsatisfactory” vitamin D levels based on physician perceptions. Physicians felt 26% of patients would benefit from additional vitamin D supplementation. However, no changes to the osteoporosis regimen were suggested for 48% of patients perceived to have “unsatisfactory” vitamin D levels. The results underscore the importance of considering vitamin D status when looking to optimize bone health.
