BACKGROUND World Health Organization (WHO) defines stroke as “rapidly developing clinical signs of focal (or global) disturbance of cerebral function, lasting more than 24 hours or leading to death, with no apparent cause other than that of vascular origin.” Low serum 25 hydroxy vitamin D is associated with large infarct volume, which worsens the outcome in ischemic stroke patients. In this study, we wanted to evaluate serum vitamin D levels in acute ischaemic stroke (AIS) patients and correlate the severity of stroke with lipid profile & central nervous system (CNS). METHODS It was a cross sectional comparative study, conducted in Department of Medicine in SGRDIMSR, Sri Amritsar from December 2018 to June 2020. A total of 100 subjects, 50 cases of AIS, diagnosed by history, clinical examination and supported by magnetic resonance imaging (MRI) of brain and 50 age and sex matched healthy controls were enrolled for the present study to estimate serum vitamin D level in AIS. Detailed clinical history and clinical examination were done on all participating subjects and relevant investigations were done. Diagnosis was confirmed by MRI brain in acute ischemic stroke cases. The severity of neurological impairment was evaluated as per Canadian neurological stroke scale within 24 hours of admission of the cases. RESULTS Mean age of cases was 62.06 ± 10.52 years and mean age of control was 59.14 ± 11.36 with maximum number of subjects were in age group of 61 - 70 years. The mean value of vitamin D in study group was 19.31 ± 9.24 while in control group, mean value was 36.42 ± 8.33, showing more serum vitamin D deficiency in cases having AIS than controls. (P value 0.021). CONCLUSIONS The present study suggests that the low serum vitamin D levels in the body is associated with more severe neurological deficit.

Low serum vitamin D levels have been associated with various vascular diseases. Very little is known its association with acute stroke in Bangladeshi population. We therefore sought to assess whether low serum 25- hydroxyvitamin D, a marker of vitamin D status is associated with acute stroke. We performed a prospective study in Comilla Medical Collage, Comilla, from November 2016 to November 2017. All the patients diagnosed as acute ischemic stroke on the basis of CT scan or MRI of brain. Patients were eligible for inclusion if they were admitted with onset of symptoms within 24 hours. Estimation of 25(OH)D level was done at presentation. The patients were stratified by vitamin D status, >30 as vitamin D sufficient, vitamin D 20-20.9 as insufficient and finally vitamin D<20 as deficient. Multivariate logistic regression analysis revealed that out of the desired 7 variables, smoking, hypertension and low serum vitamin D were found independent predictors for acute stroke with ORs being 1.44, 4.23 and 2.39 respectively. Vitamin D deficiency represents an important risk factor for acute stroke and it might play a causal role in the development adverse events associated with stroke.Medicine Today 2018 Vol.30(1): 34-37

Abstract Background Vitamin D is a critical factor in bone remodelling, calcium absorption and may promote anti-inflammatory cytokines in the gut. Inflammatory bowel disease (IBD) is associated with a reduction in serum Vitamin D levels and a chronic inflammatory state, both of which are strong risk factors for bone density loss affecting IBD patients. Despite European and North American IBD maintenance guidelines for Vitamin D monitoring and bone density scans, there are limited North American investigations into factors influencing serum Vitamin D levels in the IBD patient population specifically. Aims We investigated whether patient demographics, disease severity indexes and/or inflammatory markers were linked to low serum Vitamin D levels in our IBD patients. We also established the extent of Vitamin D serum deficiencies and supplementation rates in our IBD patients. Methods A retrospective chart review of a single clinician’s practice at London Health Science Centre, Victoria Hospital, over the past 20 months, was performed to: 1) assess the frequency of low serum 25-OH Vitamin D (25-OH D) in the IBD patient population and 2) determine whether patient disease severity was linked to lower 25-OH D levels. A multivariate regression analysis was performed assessing Crohn’s Disease (CD) or Ulcerative Colitis (UC) patient factors: age, sex, disease duration, seasonality, current pharmacologic treatments, past surgeries, CD Activity Index, UC Mayo score, C-reactive protein, and fecal calprotectin (Fcal) level. Results 175 IBD patients had at least one 25-OH D measurement with 71 patients actively on Vitamin D therapy. Of UC and CD patients who were not on Vitamin D therapy, 63% (17/27) and 79% (61/77) were 25-OH D deficient, respectively. 25-OH D levels in the CD population was associated with Vitamin D supplementation (regression coefficient [RC] 23.99, 95% confidence interval [CI] 14.54 to 33.45), summer season ([RC] 9.90, [CI] 0.56 to 19.24), and past bowel resection ([RC] -10.61, [CI] -20.48 to -0.76). 25-OH D levels in the UC population was associated with Vitamin D supplementation (regression coefficient [RC] 47.23, 95% confidence interval [CI] 27.62 to 66.83), and Mayo severity scores ([RC] -23.01, [CI] -41.82 to -4.20). Fcal (78 patients) was inversely associated with 25-OH D levels but the trend was not significant. Conclusions Overall, 25-OH D levels were lower in both the UC and CD patient populations relative to the already deficient Canadian population. However, IBD patients are responsive to Vitamin D supplementation. Tools with more objective evidence of disease severity such as UC Mayo score and fcal should be prioritized for identifying the IBD population requiring supplementation. Funding Agencies None

e19550 Background: Low serum vitamin D in cancer patients has been associated with inferior cancer outcomes and bone loss. The impact of chemotherapy on vitamin D levels is not known. We examined serum vitamin D levels during chemotherapy to identify magnitude and predictors of change. Methods: A prospective study of chemotherapy naïve patients commencing chemotherapy in two different sun exposure areas. Vitamin D (25(OH)D) deficiency was defined as ≤25 nmol/L and insufficiency 26-50 nmol/L. Demographic data, nutrition, sun exposure, season and biochemical parameters were collected at baseline 6 weeks (6W) and 12 weeks (12W) since commencement of treatment. The effects were assessed using a multivariate multilevel linear regression model that also included age, gender and BMI. Results: 82 Caucasian and 3 indigenous patients were enrolled. Median age was 57 (21-85) years. Forty-nine (58%) were female; 54 (65%) were treated with curative intent. Tumours included 29 (34%) breast,12 (14%) colorectal, 9 (11%) lymphomas, 7 (8%) leukemias, 7 (8%) lung, 5 (6%) ovarian, 3 (4%) testis, 3 (4%) unknown primary and 10 (11%) others. Median weight was 75 kg (50-151) and median BMI was 26.9 kg/m2 (17.7- 44.5). Seventy-six (89%) and 55 (65%) patients were receiving chemotherapy treatment at 6W and 12W respectively. Mean (±SD) serum 25(OH)D at baseline was 49.2±22.3 nmol/L. Ten (12%) patients were vitamin D deficient at baseline and a further 33 (41%) had insufficient levels. Mean serum 25(OH)D status was higher in higher sun exposure locations (61.9±22.1 nmol/L vs 42.2±19.2 nmol/L, p<0.001), varied according to season (spring=46.9±20.3 nmol/L, summer=50.8±18.2 nmol/L, fall=76.4±25.2 nmol/L, winter=36.5±15.7 nmol/L, p<0.001) and changed with treatment period (baseline=49.2±22.3 nmol/L, 6W=40.9±19.0 nmol/L, 12W=45.9±19.7 nmol/L, p=0.002). There was no association between 25(OH)D status and age, gender, BMI or nutritional status. Conclusions: Chemotherapy is associated with a fall in serum 25(OH)D. Further research is needed to determine the underlying mechanism, the impact of low serum 25(OH)D on patient outcomes and the potential role for screening and vitamin D supplementation in this group.

Abstract Background: Low serum vitamin D concentrations have been reported to be associated with an increased risk of non-alcoholic fatty liver disease (NAFLD). However, whether slim or obese people show a similar association between vitamin D and NAFLD remains speculative. This study aimed to explore the relationship between serum vitamin D concentrations and NAFLD in lean and obese Chinese adults.Methods: This cross-sectional study included 2538 participants (1360 men and 1178 women) who underwent their health checkups at the First Affiliated Hospital of Zhejiang University School of Medicine in 2019. NAFLD was diagnosed by liver ultrasound excluding other causes. The association of serum vitamin D concentrations with NAFLD was analyzed in lean and obese participants.Results: The overall prevalence of NAFLD was 33.61% (13.10% in lean and 53.32% in obese) in this study population. The serum vitamin D levels of obese NAFLD patients were lower than that of the obese NAFLD-free controls. However, the serum vitamin D levels of lean NAFLD patients were comparable to that of the lean NAFLD-free controls. Serum vitamin D levels were negatively correlated with the prevalence of NAFLD in obese but not lean participants. Serum vitamin D levels were independently associated with the risk of NAFLD in obese participants, with an adjusted odd ratio (95% CI) of 0.986 (0.979–0.992). However, the serum vitamin D levels were not related to the risk of NAFLD in lean participants.Conclusions: Low serum vitamin D levels are associated with NAFLD in obese but not lean participants.
