Serum Vitamin D Level in Psoriasis: A Prospective Study in a Tertiary Care Centre of Eastern India

Background: Psoriasis is a systemic, inflammatory, chronic autoimmune disease characterized by multiple discoid plaques over body with silvery scales associated with cardiovascular diseases, obesity, diabetes mellitus, hypertension, and hyperlipidemia. Recently, association between psoriasis and Vitamin D level has also been reported. Our aim of study was to evaluate the association of vitamin D and its association with the severity of Psoriasis Materials and methods: 60 patients diagnosed with psoriasis, in our outpatient department from January 2021 to December 2021, were included the study. 58 age, gender- and skin phototype- matched healthy controls were included in the study. Results: The serum vitamin D level in patients and in the control group ranged from 7 to 24 ng/ml (mean: 13.04 �32 ng/ml) and from 16 to 65 ng/ml (mean: 23.91�08 ng/ml), respectively. The circulating vit D levels were less in patients compared to control. The analysis showed statistical significance (P< 0.05) between the two groups. Conclusion: Our results showed decreased level of vitamin D in patients suffering from psoriasis when compared to healthy controls. Vitamin D supplementation can be useful in psoriasis management.

Polymorphism of Vitamin D Receptor Gene -Taq1 (RS 731236) Associated With Plasma Vitamin D Group Levels Among Breast Cancer Patients in H. Adam Malik Hospital, Medan

Aim Breast cancer was one of the most cancer occurred in women worldwide. Taq 1 polymorphism, a silent SNP,was thought to be genetic risk factor for breast cancer. This study was aimed to understand the relationshipbetween vitamin D receptor gene–Taq 1 (RS 731236) polymorphism and plasma vitamin D level among breastcancer patients in RSU H. Adam Malik Medan. Material and Methods Blood sample was collected from 53 newbreast cancer cases that had not received any chemotherapy. DNA isolation and gene amplification was doneusing PCR then followed with RFLP using Taq 1 restriction enzyme. The level of 25(OH)D was measured usingELISA. Result and Discussion Study results showed TT genotype was 92.5%, TC genotype was 7.5%, CC genotypewas 0 % using Hardy-Winberg Equilibrium (HWE) p=0.77, mean value of vitamin D level in study subject was28.16 ng/ml (CI 95%: 25.71-30.60). Fisher exact test analysis concluded that polymorphism of vitamin D receptorgene-Taq1 associated with plasma vitamin D group levels among breast cancer patients in H. Adam MalikHospital, Medan (p= 0.033) but there was no difference in mean plasma vitamin D levels between genotypegroups of Taq1 (p=0.141). Conclusion Vitamin D receptor gene-Taq1 polymorphism was associated with plasmavitamin D group level and but no significant differences in mean plasma vitamin D levels between genotypegroups of Taq1.

Is there an association between vitamin D and risk of stroke?: a North Indian study

Background: Vitamin D deficiency is present in India in epidemic proportions despite plenty of sunshine. Reduced plasma 25(OH) D concentrations as a diagnostic marker of vitamin D deficiency have been in past decade associated with several well-established risk factors for ischaemic stroke, such as arterial hypertension, thrombosis, atherosclerosis. The aims and objectives of this study was to compare the serum 25(OH) D levels between the first ever acute stroke patients and healthy controls.Methods: A cross-sectional, case control study was conducted in a tertiary care hospital in New Delhi situated in north India. Serum 25‑hydroxyvitamin D (25(OH) D) levels in 85 patients of ischemic stroke, presenting within 7 days of onset of stroke was measured and was compared with 70 age and gender matched controls.Results: The mean age was 61.02±11.58 years and 58.63±11.28 years in cases and controls respectively. Females constituted 37.6% of the total number of cases and 43.4% of the controls. The age and gender-distribution were comparable between the cases and controls. The median value (IQR) of serum 25(OH) vitamin D level was 7.94 ng/mL (4.59-14.00) in the cases and it was 8.82 ng/mL (5.59-14.70) in the controls. The difference between the serum 25(OH) vitamin D levels of the two groups was not found to be statistically significant.Conclusions: There is a high prevalence of biochemical hypo-vitaminosis D in apparently healthy Indians of all age and sex groups despite adequate sunshine. There is no association between low vitamin D levels and stroke.

Levels of vitamin D and the effect of added treatment on Multiple Sclerosis / 实用医学杂志

Objective To evaluate the serum 25?hydroxy vitamin D3 level in patients with multiple sclerosis(MS)and normal healthy population,as well as the correlation between addition of oral 1,25?hydroxy vitamin D3 and the prevention of MS relapse and progression. Methods There were 60 cases in the relapsing?remitting MS(RRMS)group and 68 cases in the healthy group,respectively;and the differences in the sex,age, serum 25?hydroxy vitamin D3 level of the two groups were counted and evaluated. In addition ,the 60 cases of patients were divided randomly into the hormone therapy group and the addition treatment group ,with 30 cases in each group;the addition treatment group was added oral calcitriol soft capsules on the basis of the hormone therapy group;EDSS score evaluation was conducted on the two groups 6,12 and 24 months after treatment,the relapse frequency was counted after 24 months,and the relapse interval was calculated. Results The serum 25?hydroxy vitamin D3 levels in the patient group and the healthy group were(18.75 ± 8.35)nmol/L and(23.28 ± 9.31)nmol/L, respectively. There were statistically significant differences in the relapse frequency (P < 0.01),the relapse interval(P < 0.05),and EDSS score(after 24 months)(P < 0.05)between the hormone therapy group and the addition treatment group after treatment;while the differences in the EDSS score (after 6 months)(P = 0.457) and the EDSS score(after 12 months)(P = 0.118)between the two groups showed no statistically significance. Conclusion The serum 25?hydroxy vitamin D3 level in MS patients was markedly lower than that in normal healthy population. Addition of 1,25?hydroxy vitamin D3 contributes to preventing the relapse rate of MS and extending the relapse interval;in addition,maintaining long?term of oral 1,25?hydroxy vitamin D3 facilitates to delaying the progression of disabled disease.

Effects of cord blood vitamin D levels on the risk of neonatal sepsis in premature infants / 소아과

PURPOSE: Vitamin D plays a key role in immune function. Vitamin D deficiency may play a role in the pathogenesis of infections, and low levels of circulating vitamin D are strongly associated with infectious diseases. In this study, we aimed to evaluate the effects of low vitamin D levels in cord blood on neonatal sepsis in preterm infants. METHODS: One hundred seventeen premature infants with gestational age of <37 weeks were enrolled. In the present study, severe vitamin D deficiency (group 1) was defined as a 25-hydroxyvitamin D (25(OH)D) concentration <5 ng/mL; vitamin D insufficiency (group 2), 25(OH)D concentration ≥5 ng/mL and <15 ng/mL; and vitamin D sufficiency (group 3), 25(OH)D concentration ≥15 ng/mL. RESULTS: Sixty-three percent of the infants had deficient levels of cord blood vitamin D (group 1), 24% had insufficient levels (group 2), and 13% were found to have sufficient levels (group 3). The rate of neonatal sepsis was higher in group 2 than in groups 1 and 3. CONCLUSION: There was no significant relationship between the cord blood vitamin D levels and the risk of neonatal sepsis in premature infants.

The relationship between serum vitamin D level and asthma severity in asthmatic children (aged 1-15 years) in Ardabil, 2012-13.

Background: Vitamin D plays an important role in many immune and allergic diseases, and its deficiency is more in areas with low solar radiation. Asthma is a common disease in children of Ardabil city. The present study was designed to evaluate vitamin D levels in asthmatic children in Ardabil. Methods: A total of 100 asthmatic children (40% boys and 60% girls) with a mean age of 5.7 ± 3.46 years (1-15 years) and who visited the Bou-Ali pediatric hospital were included. Vitamin D levels, disease course, IgE levels, and eosinophil counts were evaluated. A group of healthy children was also included to compare vitamin D levels between asthmatic and non-asthmatic children. All data were analyzed by statistical methods in SPSS v.16. Results: The vitamin D levels in asthmatic children were lower than those in the healthy group. Furthermore, the increase in the vitamin D level was significantly associated with lower history of hospitalization (P = 0.02), better response to bronchodilator treatment (P = 0.01), lower IgE level (P = 0.02), and decrease in the mean age of children (P = 0.04). However, no significant association between vitamin D levels and sex (P = 0.08), history of anti-inflammatory drug use (P = 0.78), and eosinophil count (P = 0.08) was observed in asthmatic children. Conclusion: Results showed that vitamin D deficiency was more common in asthmatic than in non-asthmatic children and the level of vitamin D was directly associated with the response of the children to treatment.

Objective To investigate vitamin D nutrition of children aging 0-6 years who received routine physical checkup in outpatient clinic,and to provide evidence for supplementation of vitamin D.Methods A total of 3 724 children were enrolled in children healthcare outpatient clinic in the Maternity and Child Health Care Hospital of Huzhou from January 2013 to March 2014.Serum 25-hydroxy vitamin D [25-(OH) D] levels of the children were measured using electrochemiluminescence to compare serum 25-(OH) D levels and vitamin D deficiency in children of different ages and in seasons.Results The mean 25-(OH) D level in these children was (37.80 ± 11.67) ng/ml,and the prevalence of vitamin D deficiency was 7.33％,neither showing significant difference between boys and girls (t =-1.57,P =0.117 ; x2 ＝ 0.37,P =0.543).The serum 25-(OH) D level in ＞3-and-≤6 years group was remarkably lower than the levels in ≤1 year,＞ 1-and-≤2 years and ＞2-and-≤3 years groups [(27.36 ±8.90) ng/ml vs.(38.64 ± 12.10) ng/ml,t =18.60,P=0.000;vs.(41.63±10.31) ng/ml,t=26.07,P=0.000;vs.(36.85±10.01) ng/ml,t=16.42,P =0.000],and the prevalence of vitamin D deficiency significanl higher than those in the other 3 age groups (104/466 vs.122/1 487,x2 =69.06,P =0.000; vs.18/1 106,x2 =196.06,P =0.000; vs.29/665,x2 =85.14,P =0.000).The serum 25-(OH) D level in children in winter was significantly lower than in spring,summer,and autumn [(35.16 ± 11.30) ng/ml vs.(40.03 ± 12.57) ng/ml,t =9.15,P =0.000;vs.(36.86±10.60) ng/ml,t=3.34,P=0.001; vs.(39.99±11.36) ng/ml,t=9.65,P=0.000],and the prevalence of vitamin D deficiency significantly higher than in the other 3 seasons (127/1 189 vs.56/ 849,x2 =10.11,P =0.001; vs.54/787,x2 =28.30,P=0.004; vs.36/899,x2 =31.71,P=0.000).Conclusions Vitamin D nutrition status of infants at 0-6 years in our child healthcare outpatient clinic is generally good,except for lower vitamin D level and higher prevalence of vitamin D deficiency in winter and ＞3-and-≤6 years age group.Therefore,vitamin D supplementation in winter and in children above 3 years old is especially important.Recommendations include more outdoor activities and public education for scientific prevention of vitamin D deficiency.

Effects of calcium intake, milk and dairy product intake, and blood vitamin D level on osteoporosis risk in Korean adults: analysis of the 2008 and 2009 Korea National Health and Nutrition Examination Survey

This study was performed to determine the effects of dietary calcium (Ca) intake, milk and dairy product intake, and serum vitamin D level on bone mineral density. The survey data from the 2008-2009 Korea National Health and Nutrition Examination Survey (KNHANES) for adults (3,819 males, 5,625 females) aged > 20 years were examined; osteoporosis was defined according to the standards for Asian populations (T-score 1 portion per day, compared with those who had zero intake. The risk for osteoporosis significantly decreased as the serum 25(OH) vitamin D level increased. From these results, we advocate an increase in Ca, milk, and dairy product intake, and that serum 25(OH) vitamin D levels be maintained within the normal range, for the maintenance of bone health and the prevention of osteoporosis in adults.
