Abstract Objectives: This study was aimed to assess maternal vitamin D status during pregnancy and  determine the association between maternal 25(OH) D levels with risk of preeclampsia (PE). Methods: A cross-sectional study was conducted with 172 pregnant women recruited from JPMC between January and December 2017 who were divided as normotensive (n=80) and pre-eclamptic (n=92) groups. Blood pressure was recorded at 20 and 32 weeks of gestation. Five ml of blood sample was collected at 20 weeks of gestation to assess the vitamin D levels by commercially available ELISA assay. Results:  PE group had a significantly higher systolic (p<0.001) and diastolic (p<0.001) blood pressure at 20 weeks of gestation. Vitamin D levels were reported to be significantly lower (p<0.001) in the PE group (17.97±9.38 ng/ml) as compared to normotensive group (42.18±25.17 ng/ml). A strong negative correlation of Vitamin D levels with systolic blood pressure (r=-0.428; p<0.001) and diastolic blood pressure (r= -0.375; p<0.001) was found. Conclusion: This study found a strong relationship between low vitamin D levels and pre-eclamptic manifestation. Keywords: Vitamin D; Pre-eclampsia; Pregnancy; Hypertension. Continuous....

Abstract Purpose Peripheral neuropathy (PN) is common in patients with multiple myeloma (MM). We hypothesized that the relationship between hypovitaminosis D and PN described in diabetes mellitus patients may also be present in MM patients. Methods To study this potential association, we assessed the incidence of hypovitaminosis D (vitamin D < 75 nmol/L [= 30 ng/mL]) in smouldering and active MM patients in two Dutch hospitals. Furthermore, a validated questionnaire was used to distinguish different PN grades. Results Of the 120 patients included between January 2017 and August 2018, 84% had an inadequate vitamin D level (median vitamin D level 49.5 nmol/L [IQR 34–65 nmol/L]; mean age: 68 years [SD ± 7.7]; males: 58%). PN was reported by 69% of patients (n = 83); however, of these 83 patients, PN was not documented in the medical records of 52%. An association was found between lower vitamin D levels and higher incidence of PN in the total population (P = 0.035), and in the active MM patients (P = 0.016). Conclusion This multi-centre cohort study showed that PN and hypovitaminosis D are common in MM patients, and addressing low vitamin D levels in the treatment of MM patients might be beneficial in reducing the risk of PN. More attention for PN is warranted, as PN is underreported by clinicians. Further research is needed to fully understand the implications of vitamin D in the development of PN in patients with MM.

Background: In Covid-19 infection, leukopenia, inflammation, and elevated liver enzymes are found in most patients. Also, vitamin D deficiency attenuate the immune system and predispose a person more susceptible to infection. In this context, we aimed to evaluate vitamin D, Electrolytes, Complete blood count, Liver enzymes, Urea, Creatinine, Albumin, CRP and ESR levels in patients with Covid-19. Methods: We conducted a cross-sectional study on 118 patients with Covid-19 who were hospitalized from 2020/2/19 to 2020/4/3 in ICU. Serum levels of electrolytes, liver enzymes, blood factors, urea, creatinine, CRP and ESR as well as anthropometric parameters and serum vitamin D concentration were measured. Results: A total of 118 patients (80 male and 38 female) was enrolled in the study (65.05±15.75 years). Only 5.08% of patients had no risk factors and 55.9% had ≥ 2 risk factors. Diabetes (44.1%) and obesity (23.7%) were more common among patients. Laboratory finding showed that 80.50% of patients had hyponatremia, but other electrolytes included K, Mg, Ca and P were normal in majority of participants as well as CBC, Cr, Urea, Alb, ALT and ALKP. The AST concentration increased in most patients (66.94%). All patients had high levels of inflammatory factors such as CRP and ESR. The mean of 25-hydroxy-vitamin D levels in participants (25.95 ± 14.56 ng/mL) was lower than its levels in general papulation. However, it was not statistically significant (P= 0.88). A significant negative correlation found between vitamin D and ALT (P= 0.02, -0.21) as well as vitamin D and CRP (P= 0.05, -0.17). Conclusion: Regarding to the regulatory role of vitamin D in immune system and low levels of vitamin D in Covid-19 infected patients, the evaluation of vitamin D levels and prescribe supplements if necessary is suggested.

Background: Authors examined serum vitamin D status among the healthy school children belonging to the south Indian state of Kerala.Methods: A cross-sectional study, participants were recruited through medical camps organized in Thrissur and Palakkad districts of central Kerala during the months of March and April 2017. A 174 healthy school children (98 males and 76 females) aged 5-13 years were recruited for the study. The children were found to be healthy on the basis of physical examination by a Paediatrician. None of the children had any symptoms of skeletal deformities. All the children were drug-naive. Data on height, weight, skin color, food habits, physical activities and socio-economic status were recorded. A 2ml of peripheral blood samples were collected from the participants. Total vitamin D in the serum was estimated by chemiluminescence immunoassay (CLIA).Results: VDD was observed in 60.92% and insufficiency in 30.46% of the participants. Only 8.62% of the participants had normal vitamin D levels. The mean vitamin D level was 19.93 ng/ml. Males had significantly higher vitamin D levels compared to females. Factors such as age, height, weight, diet, skin color and socio-economic status did not influence vitamin D levels.Conclusions: This is the first study of vitamin D status among the school-age children of Kerala. This paper adds further evidence to the reports indicating high prevalence of subclinical VDD among children across India and calls for action.

AbstractVitamin D deficiency is prevalent all over the world, especially in tropical countries. In epileptics, antiepileptic drugs (AED) and associated comorbidities further impact vitamin D status. The aim of this study is to estimate the prevalence of 25(OH) vitamin D deficiency in epileptic children and evaluate probable risk factors. A cross-sectional study of 200 children between 1 and 18 years of age on AED was undertaken in the pediatric neurology clinic of a tertiary care center of Northern India. In all children, serum 25(OH) vitamin D levels, calcium, phosphorus, and alkaline phosphatase were estimated. The deficiency levels of vitamin D were categorized as: deficiency <20 ng/mL, insufficiency 20 to 30 ng/mL, and sufficiency >30 ng/mL. The potential risk factors for hypovitaminosis D, including type of epilepsy, AED regimen (specific medications, polytherapy vs. monotherapy), cerebral palsy, ambulatory status, intellectual disability, body mass index, gender, and vegetarianism were examined. Among the 200 enrolled children (60% boys), 106/200 (53%) were vitamin D deficient. There was no significant relation of vitamin D levels with gender, type of epilepsy, neurological deficit, and type of AED. An inverse relationship of higher phenytoin doses during monotherapy associated with lower vitamin D levels in monotherapy was found, thereby suggesting adverse effect of high doses of phenytoin on vitamin D levels. VDD is common among epileptic children on AED therapy. Vitamin D deficiency is common prevalent among epileptic children on AED therapy, and its detection and treatment correction should be an integral part of epilepsy management.

AIM: A cross-sectional study was conducted at Saad Abualila Hospital (Khartoum, Sudan) to evaluate the vitamin D levels and thyroid function among pregnant Sudanese women (132) in early pregnancy.METHODS: A cross-sectional study was conducted at Saad Abualila hospital (Khartoum, Sudan) during the period from March to July 2015. Women who were in early pregnancy with a singleton pregnancy were approached to participate in the study after signing informed consent. A sample size of 132 participants was calculated guided by the normal interval of thyroid function in Sudanese women in the first trimester and not the level of 25(OH) vitamin D. The 25 - hydroxyvitamin D (25 (OH) vitamins levels were measured using an electrochemiluminescence immunoassay on an Elecsys 2010 Analyzer (Roche Diagnostics, Mannheim, Germany).RESULTS: The mean (SD) of age, gravidity and gestational age was 27.6 (5.5) years, 2.2 (1.6) and 10.4 (2.2) weeks, respectively. The mean (SD) of the body mass index (BMI) and haemoglobin was 27.1 (5.2) kg/m2 and 10.8 (1.1) g/dl, respectively. Median (interquartile) values of TSH, FT3, and FT4 were 1.164 IU/ml (0.079 -2.177 IU/ml), 4.639 nmol/l (3.843 - 6.562 nmol/l), and 16.86 pmol/l (13.02 - 31.48 pmol/l), respectively. There was no significant correlation between vitamin D levels and TSH, FT3 and FT4CONCLUSION: There is no correlation between 25 (OH) vitamin D levels and thyroid function during early pregnancy among Sudanese pregnant women, despite prevalent vitamin D deficiency among these women.
