Correlation between Serum Vitamin D levels and hypertensive disorders in pregnancy in primigravida in third trimester

Background: This study was done to evaluate the association of serum vitamin D level with GDM (n=30) and without GDM (n=30). The age and body mass index of the participants along with their gestational age, gravidity and parity were harmonized. The serum vitamin D levels and blood glucose were investigated. The results revealed that, normal pregnant women had significantly higher vitamin D level than their GDM counterparts.Methods: This case-control study was conducted on healthy pregnant women attending routine antenatal care at Bangabandhu Sheikh Mujib medical university from January 2019 to December 2019 recruited at third trimester of gestation. We measured maternal serum vitamin D status (25[OH]D) in third trimester of pregnancy. GDM was diagnosed according to the American diabetes association. guidelines. Vitamin D status was defined as, vitamin D sufficiency (≥30 or ≥75 nmol/L), insufficiency (20-30 and 50-75 nmol/L), were used to categories participants according to their 25[OH]D concentrations. We calculated adjusted odds ratios and 95% confidence intervals (CIs) using logistic regression.Results: The mean serum vitamin D level was lower in case group case 23.4 (17.4±35.1) compared to that in control group 29.7 (15.4±39.8) and the difference between the 2 groups was statistically significant (p≤0.001). Sufficient level of vitamin D was more in control group (66.7%) than that of case group (26.1%). Insufficient level of vitamin D was higher in case (73.3%) group than that of control (33.3%) group. These findings were significant (p=0.021). Respondents with insufficient level of vitamin D have 3.1 times more chance to develop GDM.Conclusions: Serum vitamin D level is reduced in pregnant women having GDM.

Background: Current study was conducted with the objective to evaluate maternal vitamin D levels in patients with hypertensive disorders of pregnancy.Methods: The present prospective observational study was conducted among 200 pregnant women attending gynaecological OPD of Subharti medical college, Meerut, over a period of two years and satisfying the inclusion criteria were enrolled. On admission, patient demographic profile, complete history was recorded, and comprehensive clinical examination was done. In all the patients, blood samples for routine examination along with LFT, RFT, random blood sugar, serum electrolytes, serum uric acid and serum vitamin D were drawn, and serum levels of these biochemical parameters were determined according to standard laboratory procedures. Subjects were classified into three categories according to serum vitamin D level i.e. >20 ng/ml (mild), 10-20 ng/ml (moderate deficiency), <10 ng/ml (severe deficiency).Results: Insignificant difference was found between case (hypertensive) and control (normotensive) group when compared in relation to age, education, parity and socioeconomic status. The mean vitamin D level of women with HDP was 5.7+2.99 ng/ml as compared to 17.34+5.79 ng/ml in normotensive women with statistically significant difference as p<0.001. No correlation was found between severity of vitamin D deficiency and maternal complications (p=0.318).Conclusions: The results of the present study concluded that women with hypertension had significantly lower vitamin D level as compared to normotensive women.

Background: The aim of this study was to compare vitamin D level in normal pregnant women and patients of hypertensive disorders of pregnancy and to study the prevalence of vitamin D deficiency in patients of hypertensive disorders of pregnancy and normal pregnant women.Methods: 50 women affected by hypertensive disorders of pregnancy and 50 normal pregnant women more than 20 weeks of gestation, admitted to the ward or to labour room in the Obstetrics and Gynaecology Department, of Mahatma Gandhi Medical College and Hospital were enrolled in the study. Assessment of serum 25 hydroxy vitamin D was done by chemiluminescent immunoassay method.Results: Serum vitamin D levels were low in women with hypertensive disorders of pregnancy with mean serum vitamin D level 13.66±7.358 ng/ml as compared to normal normotensive pregnant women 21.14±8.241ng/ml, which is statistically significant (p=0.001). Mean vitamin D level in study population was 17.40±8.634 ng/ml. The prevalence of vitamin D deficiency in hypertensive disorders of pregnancy group was very high 88% compared to 50% in normal normotensive pregnant women group. The difference was statistically significant (p=0.001). vitamin D deficiency was found among 69% in study population. Conclusions: Vitamin D levels are deficient in patients of hypertensive disorders of pregnancy as compared to normal pregnant women. There is increased prevalence of vitamin D deficiency with hypertensive disorders of pregnancy suggesting that vitamin D deficiency can be a risk factor for the development of hypertensive disorders of pregnancy.

Abstract. We aim to assess the prevalence of vitamin D deficiency (VDD) in patients scheduled for bariatric surgery (BS), and to identify factors that might be associated with VDD. We conducted a cross-sectional observational study involving all consecutive patients scheduled for BS from 2017 to 2019. The exclusion criteria were missing data for vitamin D levels, intake of vitamin D supplements in the 3 months prior to serum vitamin D determination, and renal insufficiency. A total of 206 patients (mean age and body mass index [BMI] of 34.9 ± 10.7 years, and 44.3 ± 6.99 kg/m2, respectively) met the inclusion criteria and were enrolled for data analysis. VDD (<19.9 ng/mL), severe VDD (<10 ng/mL), and vitamin D insufficiency (20–29.9 ng/mL) were present in 68.8 %, 12.5 %, and 31.2 % of patients, respectively. A significant inverse correlation was found between vitamin D levels and initial BMI, parathyroid hormone, and homeostatic model assessment of insulin resistance (r = −0.280, p < 0.05; r = −0.407, p = 0.038; r = −0.445, p = 0.005), respectively. VDD was significantly more prevalent in patients with higher BMI [−0.413 ± 0.12, CI95 % (−0.659; −0.167), p = 0.006], whereas no significant association between hypertension [−1.005 ± 1.65, CI95 % (−4.338; 2.326), p = 0.001], and diabetes type 2 (T2D) [−0.44 ± 2.20, CI95 % (−4.876; 3.986), p = 0.841] was found. We observed significant association between female sex and levels of vitamin D [6.69 ± 2.31, CI95 % (2.06; 11.33), p = 0.006]. The present study shows that in patients scheduled for BS, VDD deficiency is common and was associated with higher BMI, and female sex.

Background: The risk factors for asthma exacerbations are well understood. However, the effect of vitamin D levels on number of asthma exacerbations per year is not clearly studied. The objective of the study was to ﬁnd out the association of serum vitamin D levels and asthma risk factors on asthma exacerbations. Methods: In this study, ninety-nine subjects from 5 to 15 years of age were recruited at an episode of acute exacerbation. It was a cross sectional study and carried out from 2012 to 2015. Pulmonary function test was done by spirometry. Asthma exacerbation was labeled when forced expiratory volume/ forced vital capacity (FEV1/FVC) ratio was less than 80% (American Thoracic Society). Global Initiative for Asthma (GINA) guidelines were used to classify asthma into mild, moderate and severe persistent asthma. Serum vitamin D levels were measured by chemiluminescence method. Pearson Chi-square test was applied and p value (p<0.05) was considered as statistically signiﬁcant. Results: Children who had exposure to animal dander had signiﬁcantly lower asthma exacerbations per year (p-value <0.046). There was no signiﬁcant association between vitamin D levels and number of exacerbations per years (p-value <0.099). Asthma was prevalent in girls of low socioeconomic status (SES) compared to males. However, there was no signiﬁcant association between smoke, exercise, home environment, food allergies, weather, pollen and dust with asthma exacerbations. Conclusion: Low levels of vitamin D were not associated with increased number of asthma exacerbations per year. However, children exposed to animal dander had lesser number of exacerbations per year (p-value <0.046). Keywords: Asthma; Vitamin D; Children; Exacerbations, Risk factors.
