Abstract Objective: Vitamin D plays a crucial role in calcium metabolism through the Parathyroid hormone (PTH) dependent process. The deficiency of this important nutrient may be associated with hypocalcemia after thyroidectomy. To evaluate the role of vitamin D in predicting hypocalcemia following total thyroidectomy.Results: sixty-two patients who underwent total thyroidectomy for benign or malignant thyroid disease were included in this prospective study. Preoperative vitamin D serum levels and PTH levels were determined. The results of our study showed In both groups with and without vitamin D deficiency, calcium levels decreased significantly (P = 0.01). In our study, it was found that there was no significant relationship between postoperative hypocalcemia and vitamin D deficiency. (P = 0.441). After reviewing the data and according to Spearman correlation statistical test, no significant relationship was observed between serum PTH and calcium after thyroidectomy (P = 0.340).Vitamin D deficiency is a risk factor of hypocalcemia after total thyroidectomy for benign goiter. Although post thyroidectomy hypocalcemia is multifactorial, vitamin D deficiency, particularly severe form, is significantly associated with the development of biochemical and clinical hypocalcemia vitamin D supplementation can prevent this unwanted complication in such patients.

Vitamin D plays a crucial role in calcium metabolism through the parathormone-dependent process. The deficiency of this important nutrient may be associated with hypocalcemia after thyroidectomy. To evaluate the role of vitamin D in predicting hypocalcemia following total thyroidectomy. In this study, sixty-two patients who underwent total thyroidectomy for benign or malignant thyroid disease were included in this prospective study. Preoperative vitamin D serum levels and parathormone (PTH) levels were determined. The association between preoperative vitamin D status and the development of hypocalcemia was investigated. In this study, 62 patients were evaluated. The mean age of the subjects was 47 years. Of the 62 patients studied, of which 9 were male patients (14.5%), and 53 were female (85.5%), the results of our study showed. In both groups with and without vitamin D deficiency, calcium levels decreased significantly (P=0.01). In our study, it was found that there was no significant relationship between postoperative hypocalcemia and vitamin D deficiency. (P=0.441). After reviewing the data and according to Spearman correlation statistical test, no significant relationship was observed between serum parathyroid hormone (PTH) and calcium after thyroidectomy (P=0.340). Vitamin D deficiency is a risk factor of hypocalcemia after total thyroidectomy for benign goiter. Although post thyroidectomy hypocalcemia is multifactorial, vitamin D deficiency, particularly severe form, is significantly associated with the development of biochemical and clinical hypocalcemia. Vitamin D supplementation can prevent this unwanted complication in such patients.

Background: Vitamin D has a significant role to play in bone metabolism and neuromuscular function. Several researchers have indicated that Vitamin D deficiency may be possibly related to chronic musculoskeletal pain including chronic low back pain (CLBP). Objectives: The present study was conducted to determine the prevalence of hypovitaminosis D and its contribution to chronic lower back pain. Study Design: Controlled study Setting: Outpatient pain clinic of tertiary care hospital. Methods: Data presented in this manuscript are from patients who were screened for inclusion in an open label, single arm clinical trial aimed to assess the effectiveness of vitamin D supplementation in patients with CLBP. Consecutive patients visiting the outpatient pain clinic of a tertiary care hospital with a diagnosis of CLBP with or without leg pain were recruited. A visual analogue scale (VAS) was used to measure low back pain intensity, and the Modified Oswestry disability questionnaire (MODQ) was used to measure functional ability. Plasma 25-OHD levels of all patients were measured and the prevalence of hypovitaminosis D was calculated. The multivariate logistic regression model was used to investigate the association between vitamin D deficiency and patient characteristics. Results: A total of 328 patients were included in the study. Mean age of the study population was 43.8 years. Two hundred eighty-two (86%) (men 153/172 [89%], women 129/156 [83%]) of patients had below normal plasma vitamin D levels. Among these, 217 (66%) (men 126 [73%], women 91 [58%]) were found to be deficient and 65 (20%) (men 27 [16%], women 38 [24%]) were had insufficient levels. Multivariate regression analysis found that men were significantly more prone to have deficiency as compared to women (OR = 1.78 (1.10 – 2.88), P = 0.02). We also found a significantly positive relationship between vitamin D deficiency and increased functional disability (OR = 1.53 (1.24 – 1.87), P = 0.01). However, we did not find any relationship with pain severity, presence of other co-morbidities and educational level. Limitations: Not possible to access a good quality data on sun exposure and vitamin D dietary inake dieat in study population. No bone scans were performed. Conclusion: The result of this study provides a message about the high prevalence of hypovitaminosis D in the Indian CLBP population. Clinical guidelines for managing CLBP should include assessment of vitamin D status, together with advice on appropriate vitamin D supplementation in those found to be deficient.

Background: Female pattern hair loss is also observed in women without increased androgen levels. Vitamin D is a factor that has recently been considered in dealing with these patients. Deficiency of Vitamin D might be correlated with diffuse hair loss. Objective: To determine the frequency of serum levels of Vitamin D3 in patients with female pattern of hair loss (FPHL) at tertiary care hospital Karachi. Methodology: This cross-sectional research was conducted upon a sample of 163 female patients (chosen via non-probability – consecutive sampling) presenting to the Dept. of Dermatology, Abbasi Shaheed Hospital, Karachi from 29th July 2018 to 28 th January 2019, with a clinical diagnosis of FPHL. Data was recorded onto a structured questionnaire containing inquiries pertaining to basic biodata, sociodemographic details, and inferences obtained from blood tests (CBC, serum ferritin, TSH level and vitamin D level). Serum 25 OH Vitamin D level < 20 was taken as deficient, 21-29 was insufficient and over 30 was sufficient. Data was analyzed using SPSS. v. 21.0. Results: The mean age was 30.39±6.36 years. Mean FPHL duration was 5.85±2.89 months. Total 63.2% patients were classified as mild, 26.45% patients were classified as moderate and 10.4% patients were classified as severe. Total 73% patients were found as vitamin D deficient, 22.1% as vitamin D insufficient and 4.9% as vitamin D sufficient. Significant association of vitamin D deficiency was observed with education status, vitamin D intake since past 6 months, and socio economic status. Conclusion: Results showed high vitamin D3 deficiency (73.0%) among patients with female pattern of hair loss (FPHL).

Background: Vitamin D is a fat-soluble vitamin which has immunomodulatory and anti-inflammatory effects. Vitamin D deficiency is a worldwide problem and yet is one of the most under diagnosed and under treated nutritional deficiency. Despite India being in the tropical zone with plentiful sunlight, there is a wide prevalence of vitamin D deficiency.Methods: Cross sectional descriptive study done in a tertiary care hospital involving 30 mother baby dyads equally divided into term and preterm babies. Maternal vitamin D levels (before delivery) and cord blood vitamin D levels (after delivery) were estimated.Results: All the mothers had low vitamin D levels, 93% having deficiency and 7% having insufficiency. The maternal vitamin D levels correlated with cord blood vitamin D levels. There was significant correlation between maternal vitamin D levels and cord blood vitamin D levels with maternal age and parity. There was no correlation between maternal vitamin D levels with gestational age, sociodemographic profile or neonatal anthropometry.Conclusions: Vitamin D deficiency is widely prevalent even in well-nourished mothers. Vitamin D supplementation may be helpful in antenatal mothers. Larger studies are needed to study the prevalence of vitamin D deficiency in mothers and babies and look for effectiveness of supplementation.

Background: In the recent years there has been an increased understanding of the role that vitamin D plays in regulation of cell growth, calcium absorption and immunity and its impact on the developing fetus and maternal health is of significant concern. This study aims at evaluating the Vitamin D status in pregnant women and their newborns.Methods: A cross sectional study was done on 100 pregnant females according to inclusion and exclusion criteria. At the time of delivery, maternal blood was collected, and newborn samples were taken from newborn side of umbilical cord and sent for analysis.Results: The prevalence of Vitamin D deficiency has been found to be 85% of pregnant females and 91% of the newborns. Only 5% of pregnant females and 1% of the newborns showed Vitamin D sufficiency. Maternal and newborn vitamin D levels show a positive correlation. Mean maternal and newborn Vitamin D levels were found to be 16.78±7.04 ng/mL and 11.29±5.75 ng/ml.Conclusions: Vitamin D deficiency is highly prevalent among pregnant women in north India. Low maternal vitamin D levels lead to vitamin D deficiency in the newborns also.

AbstractAnemia and vitamin D deficiency are conditions that both result in significant morbidity and increase with age. The potential relationship between them remains poorly understood, particularly in the elderly. We used the Third National Health and Nutrition Examination Survey to examine the association of vitamin D deficiency with anemia subtypes in persons aged ≥ 60 years. Vitamin D deficiency was defined as serum levels < 20 ng/mL, and anemia was defined according to World Health Organization criteria. Vitamin D deficiency was associated with anemia prevalence independent of age, sex, or race/ethnicity (odds ratio, 1.47; 95% confidence interval, 1.06-2.05; P = .02) and varied significantly by anemia subtype (P overall = .003). The prevalence of vitamin D deficiency was 33.3% in the nonanemic population, 56% in anemia of inflammation (AI; P = .008), and 33.0% in unexplained anemia (P = .55). Non-Hispanic blacks had a 7-fold increased risk of AI compared with whites, and this was partially attenuated after adjusting for vitamin D deficiency. These data show that vitamin D deficiency is associated with specific subtypes of anemia in the elderly, especially in those with AI. Vitamin D may suppress inflammatory pathways, and studies to determine whether vitamin D supplementation ameliorates AI are warranted.

Vitamin D deficiency has been correlated with the infertility and lower clinical pregnancy following IVF. Anti-Mullerian hormone (AMH) plays a key role during follicle development; it has been recognised as a predictor of regular ovulation and probably IVF success. Considering the critical need for experimental human study to investigate the impact of vitamin D supplementation on ovulatory function, the aim of this study was to demonstrate the effectiveness of the vitamin D supplementation on AMH serum levels among reproductive-age women with vitamin D deficiency. 195 reproductive women (18–35 year-old) with confirmed vitamin D deficiency [serum 25(OH)D <75 nmol L–1] and without diagnosed polycystic ovary syndrome (PCOS) were enrolled to this controlled clinical trial. Participants were randomly assigned to a control group (n = 96) or an intervention group (n = 99). Women in the intervention group used 2000 IU day–1 vitamin D drops for 15 weeks. 19 participants were missed during the follow-up; finally the numbers of women in the intervention and control groups were 91 and 85, respectively. At the beginning of the study and after the intervention, 25-hydroxyvitamin D and AMH serum levels were quantified using enzyme immunoassay (EIA; Immunodiagnostic Systems, Boldon, UK) and ELISA (Beckman-Coulter Inc., Fullerton, CA, USA) methods respectively. The post-intervention AMH measurement was performed after 2–5 weeks in the same day-of-cycle on which basal AMH measurement was done. Paired t-test, independent t-test, and Pearson correlation were used as appropriate and a P-value of less than 0.05 was considered significant. Significantly low AMH levels were seen in the vitamin D deficient women of this study (14.46 ± 11.92 pmol L–1 in control group and 14.09 ± 11.52 pmol L–1 in intervention group). After the intake of vitamin D supplementation in intervention group, AMH levels were increased to 24.89 ± 12.47 pmol L–1, which were significantly different from the 15.43 ± 13.03 pmol L–1 in control group (P < 0.001). Correlation coefficients for AMH with pre-intervention and post-intervention vitamin D were r = 0.489 and r = 0.599 respectively (P < 0.001). Treatment of vitamin D deficiency increases AMH to the optimum levels. Vitamin D deficient women had low levels of AMH. These findings support other studies which found a correlation of poor IVF outcomes with low vitamin D levels. Vitamin D supplementation could be useful in the improvement of controlled ovarian hyper-stimulation/IVF outcomes in case of vitamin D deficiency.

Vitamin D deficiency is a global health problem due to its high prevalence and its negative consequences on musculoskeletal and extra-skeletal health. In our comparative review of the two exogenous vitamin D supplementation options most used in our care setting, we found that cholecalciferol has more scientific evidence with positive results than calcifediol in musculoskeletal diseases and that it is the form of vitamin D of choice in the most accepted and internationally recognized clinical guidelines on the management of osteoporosis. Cholecalciferol, unlike calcifediol, guarantees an exact dosage in IU (International Units) of vitamin D and has pharmacokinetic properties that allow either daily or even weekly, fortnightly, or monthly administration in its equivalent doses, which can facilitate adherence to treatment. Regardless of the pattern of administration, cholecalciferol may be more likely to achieve serum levels of 25(OH)D (25-hydroxy-vitamin D) of 30–50 ng/mL, an interval considered optimal for maximum benefit at the lowest risk. In summary, the form of vitamin D of choice for exogenous supplementation should be cholecalciferol, with calcifediol reserved for patients with liver failure or severe intestinal malabsorption syndromes.
