AIM To identify the predictors of vitamin D deficiency in patients with and without inflammatory bowel disease (IBD). METHODS Patients with ulcerative colitis (UC) or Crohn's disease (CD) related diagnostic codes who received medical care at University of Mississippi Medical Center between July 2012 and 2015 were identified. After thorough chart review, we identified patients with biopsy proven IBD who had also been tested for serum 25-hydroxyvitamin D [25(OH)D] concentration. We compared these patients to a previously studied cohort of healthy controls who also had vitamin D concentration checked. Logistic regression analysis was performed to determine the association between vitamin d deficiency and UC, CD, race, age, gender and body mass index (BMI). RESULTS We identified 237 patients with confirmed IBD. Of these, only 211 had a serum 25(OH)D concentrations available in the medical record. The group of healthy controls consisted of 98 individuals with available serum 25(OH)D concentration. 43% of IBD patients were African American (AA). Patients with CD were more likely to have vitamin D concentration checked. Bivariate analysis showed that AA (51% vs 21%, P

Introduction: there are few data on the prevalence of vitamin D deficiency in patients with inflammatory bowel disease (IBD) in Spain. A deficiency could be associated with a worse course of the disease. Aim: to determine the prevalence of 25-hydroxyvitamin D (25OHD) deficiency in a cohort of outpatients with IBD and assess its association with clinical and biological activity, quality of life and psychological symptoms. Methods: a cross-sectional, single-center observational study was performed. The study variables were obtained via clinical interviews, medical chart review and validated questionnaires (Hospital Anxiety and Depression Scale and Short Quality of Life in Inflammatory Bowel Disease Questionnaire). 25OHD was measured in the same laboratory by an electro-chemiluminescence immunoassay. Results: the study included 224 patients. The prevalence of vitamin D deficiency in Crohn's disease and ulcerative colitis was 33.3% and 20.3%, respectively. In Crohn's disease, vitamin D deficiency was associated with a higher clinical activity (p < 0.001) and a higher concentration of fecal calprotectin (p = 0.01). In ulcerative colitis, it was associated with clinical activity (p < 0.001), the use of steroids during the last six months (p = 0.001) and hospital admission during the previous year (p = 0.003). A subanalysis of 149 patients failed to detect an association between vitamin D and quality of life or the scores of the Hospital Anxiety and Depression Scale. Conclusions: vitamin D deficiency is common in patients with inflammatory bowel disease. An association was found between vitamin D concentration and clinical activity indexes, as well as fecal calprotectin levels in Crohn's disease.

-Inflammatory bowel disease (IBD) patients with vitamin D deficiency show an increased risk of hospital admission, surgery, and loss of response to biologic therapy while high vitamin D levels are identified as a protective factor. Our goal was to investigate the prevalence of untreated and undertreated vitamin D deficiency and factors associated with vitamin D deficiency. In this cross-sectional study, we measured serum vitamin D in a random sample of Caucasian IBD patients. Vitamin D deficiency was defined as <50 nmol/L and insufficiency as 50-75 nmol/L. Supplementation was defined as taking 800-2000 IU vitamin D daily. Untreated patients were defined as not taking supplementation and undertreated group as receiving supplementation but showing vitamin D deficiency or insufficiency despite treatment. Our study included 185 IBD patients, i.e. 126 (68.1%) with Crohn's disease (CD) and 59 (31.9%) with ulcerative colitis (UC). Overall, 108 (58.4%) patients had vitamin D deficiency and 60 (32.4%) patients vitamin D insufficiency. There were 16 (14.8%) and 11 (18.3%) treated patients in vitamin D deficiency and vitamin D insufficiency group, respectively. The rate of untreated patients was 81.7% (n=49) in vitamin D deficiency group and 85.2% (n=92) in vitamin D insufficiency group. Tumor necrosis factor alpha inhibitors were associated with higher serum vitamin D levels in CD and UC, and ileal involvement, ileal and ileocolonic resection with lower levels. In conclusion, not only is vitamin D deficiency common in IBD patients but the proportion of untreated and undertreated patients is considerably high. We suggest regular monitoring of vitamin D levels in IBD patients regardless of receiving vitamin D supplementation therapy.
A Prospective Study of Vitamin D Status and Risk of Incident Crohn's Disease and Ulcerative Colitis
Gastroenterology, 2011
Background and aim of the work: There is increasing interest in the role of vitamin D in inflammatory bowel disease(IBD),outside of its traditional role in metabolic bone disease. Novel insights into additional roles for vitamin D are being established and these include anti-inflammatory and immune modulating effects. Therefore, this study was planned to assess the level of vitamin D variations among ulcerative colitis patients in Egypt. After departmental ethical committee approval and participants consent were obtained Twenty(20) patients with ulcerative colitis(UC) (group I), and Ten(10) apparently healthy persons (group II) as control group were enrolled in the study. Ulcerative colitis patients was diagnosed through, full history taking, clinical assessment, laboratory investigations, colonoscopic and histopathological studies. The control group was subjected to diagnostic modalities aspatients group apart from Colonoscopic and histopathological studies, and matched with patients group for age and sex. Group (1) ages ranged from 21-60 years, mean age was (36.95) 13 were females (65%) and 7 were males (35%). Group (11) ages ranged from 20-58 years, mean age was (37.60) 6 were females(60%) and 4 were males (40%). Results of this study revealed: The mean serum values of 25(OH) vitamin D in patients group(I) were lower in comparison to control group (II) (23.0±13.49 ng/dl and 36.2±5.9 ng/dl) respectively. This difference was statistically significant (P<0.007). Laboratory data of studied groups showed statistically significant difference between controls and patients group regarding HB, C-reactive protein, and serum calcium levels (P-value 0.000) respectively, as there were decreased level of HB and serum calcium in patients group compared to controls, however, increased CRP levels in patients group. White blood cells (WBCs) was higher in patients group compared to controls. In ulcerative colitis patients, there were inverse correlation between frequency of bloody stools/day and CRP with vitamin D levels which statistically significant (P= 0.003, 0.000) respectively. Serum calcium and vitamin D levels were in direct correlation and statistically significant (P=0.000). There were no correlation between age, WBCs, platelets, s. albumin, s. creatinine and INR with vitamin D levels. The patient group was classified into 3 subgroups: deficiency subgroup (9 patients) with main serum values of 25(OH) vitamin D (14.4±2.86 ng/ml), insufficiency subgroup (8 patients) (24.19±2.76 ng/ml) and sufficiency subgroup(3 patients) (33.67±3.06 ng/ml.). There was an evidence of exacerbation of activity of ulcerative colitis correlated to the degree of decreasing of vitamin D level. There were significant increase in frequency of bloody stool motions/day, ESR, and C-reactive protein (CRP), with the degree of decrease of vitamin D levels in patients subgroups. However, there were decrease of haemoglobin, serum phosphate & calcium with the degree of lowered vitamin D level in patients with ulcerative colitis. Conclusions: vitamin D [25(OH) D] deficiency is common in ulcerative colitis patients, the increased the degree of vitamin D deficiency, is associated with the increased the degree of activity of ulcerative colitis disease, which may support suggestion of vitamin D level is a potential contributing factor underlying the pathogenesis and disease activity of ulcerative colitis.

Objective To evaluate the serum concentrations of vitamin D and their relation with inflammatory bowel diseases. Methods This is a quantitative and descriptive study, with individuals assisted by the interdisciplinary ambulatory of Inflammatory Bowel Disease of the Family and Community Health Unit of Itajaí/SC from September 2015 to October 2016. Socioeconomic data, life habits, and biochemical tests were collected, with the use of clinical indexes of classification of the disease activity: Harvey-Bradshaw Index (Crohn's Disease) and Partial Mayo Score (Chronic Nonspecific Ulcerative Colitis). Results Of the 60 patients evaluated, 57% (n = 34) had Crohn's Disease and 43% (n = 26) had Chronic Nonspecific Ulcerative Colitis. According to disease activity, 75% (n = 45) were in the remission phase, 13% (n = 8) had mild activity, and 9% (n = 5) had moderate activity. Regarding vitamin D, 63% (n = 38) had deficiency of this vitamin and 37% (n = 22) presented sufficiency. With the ...

Background and aims: Vitamin D deficiency impacts on bone health and has potential new roles in inflammation. We aimed to determine the prevalence of and risk factors for vitamin D deficiency and to explore vitamin D supplement usage in patients with Crohn's disease (CD) in an outpatient setting, compared with controls. Methods: Serum 25-hydroxyvitamin D [25(OH)D] concentrations were measured by radioimmunoassay in 151 participants, comprising 81 CD patients and 70 age-, sex-and socio-economic status-matched healthy controls. Levels of 25(OH)D b 50 nmol/L were classed as deficient. Data on vitamin supplement usage were recorded for all participants at interview. Results: Vitamin D deficiency was common in patients with CD (63%) and significantly higher in winter than summer (68% v 50%; p b 0.001, χ 2 ). Notably, the deficiency rate remained high even in summer (50%). On regression analysis, 25(OH)D levels were inversely associated with winter season. Disease-specific factors for lower serum 25(OH)D levels were longer disease duration and smoking. Overall, 43% of patients reported using a vitamin D-containing supplement, primarily at low dosages (200-400 IU/d); however, this level of supplement did not prevent deficiency. For the majority of CD patients, 25(OH)D remained below optimal levels proposed to confer bone and immune health benefits. Conclusions: Vitamin D deficiency was common in patients with CD and associated with longstanding disease, smoking and winter. While over 40% of patients used a vitamin D-containing supplement, the dosages were inadequate to prevent deficiency. Appropriate vitamin D screening and supplementation should be considered in the context of health promotion of outpatients with CD.

Introduction Ulcerative colitis is an immunologically mediated disorder affecting the gastrointestinal tract. Vitamin D3 has been shown to modulate many immunological diseases, but its role in ulcerative colitis is not well documented. This study was done to find out if levels of vitamin D are associated with the severity of disease and quality of life in ulcerative colitis patients. Methods This cross-sectional study consists of two parts. The first part consists of having a comparative assessment of baseline parameters of newly diagnosed ulcerative colitis patients and healthy controls. The 2nd part consists of an evaluation of the association of levels of vitamin D3 with disease severity and quality of life in ulcerative colitis. Independent predictors of disease severity and quality of life were assessed using multiple linear regression. Results Vitamin D levels were significantly lower in healthy controls compared to newly diagnosed ulcerative colitis patients. Median ulcerativ...

We determined the association between vitamin D status as 25hydroxyvitamin D [25(OH)D] and disease activity in a cohort of 201 Crohn's Disease (CD) patients in Saskatoon, Canada over three years. The association between high-sensitivity C-reactive protein (hs-CRP) and 25(OH)D and several disease predictors were evaluated by the generalized estimating equation (GEE) over three time-point measurements. A GEE binary logistic regression test was used to evaluate the association between vitamin D status and the Harvey-Bradshaw Index (HBI). The deficient vitamin D group (≤29 nmol/L) had significantly higher mean hs-CRP levels compared with the three other categories of vitamin D status (p < 0.05). CRP was significantly lower in all of the other groups compared with the vitamin D-deficient group, which had Coef. = 12.8 units lower (95% CI -19.8, -5.8), Coef. 7.85 units (95% CI -14.9, -0.7), Coef. 9.87 units (95% CI -17.6, -2.0) for the vitamin D insufficient, adequate, and optimal g...

AIM: To investigate the effect of vitamin D (VD) concentrations and VD supplementation on health related quality of life in inflammatory bowel disease (IBD) patients. METHODS: A cohort of 220 IBD patients including 141 Crohn's disease (CD) and 79 ulcerative colitis (UC) patients was followed-up at a tertiary IBD center. A subgroup of the cohort (n = 26) took VD supplements for > 3 mo. Health related quality of life was assessed using the short IBD questionnaire (sIBDQ). VD serum concentration and sIBDQ score were assessed between August and October 2012 (summer/autumn period) and between February and April 2013 (winter/spring period). The mean VD serum concentration and its correlation with disease activity of CD were determined for each season separately. In a subgroup of patients, the effects of VD supplementation on winter VD serum concentration, change in VD serum concentration from summer to winter, and winter sIBDQ score were analyzed. RESULTS: During the summer/autumn and the winter/spring period, 28% and 42% of IBD patients were VD-deficient (< 20 ng/mL), respectively. In the winter/spring period, there was a significant correlation between sIBDQ score and VD serum concentration in UC patients (r = 0.35, P = 0.02), with a trend towards significance in CD patients (r = 0.17, P = 0.06). In the winter/spring period, VD-insufficient patients (< 30 ng/mL) had a significantly lower mean sIBDQ score than VD-sufficient patients; this was true of both UC (48.3 ± 2.3 vs 56.7 ± 3.4, P = 0.04) and CD (55.7 ± 1.25 vs 60.8 ± 2.14, P = 0.04) patients. In all analyzed scenarios (UC/CD, the summer/autumn period and the winter/spring period), health related quality of life was the highest in patients with VD serum concentrations of 50-59 ng/mL. Supplementation with a median of 800 IU/d VD day did not influence VD serum concentration or the sIBDQ score. CONCLUSION: VD serum concentration correlated with health related quality of life in UC and CD patients during the winter/spring period.
Vitamin D deficiency in a European inflammatory bowel disease inception cohort: an Epi-IBD study
European journal of gastroenterology & hepatology, 2018
Serum vitamin D level is commonly low in patients with inflammatory bowel disease (IBD). Although there is a growing body of evidence that links low vitamin D level to certain aspects of IBD such as disease activity and quality of life, data on its prevalence and how it varies across disease phenotype, smoking status and treatment groups are still missing. Patients diagnosed with IBD between 2010 and 2011 were recruited. Demographic data and serum vitamin D levels were collected. Variance of vitamin D level was then assessed across different treatment groups, disease phenotype, disease activity and quality of life scores. A total of 238 (55.9% male) patients were included. Overall, 79% of the patients had either insufficient or deficient levels of vitamin D at diagnosis. Patients needing corticosteroid treatment at 1 year had significantly lower vitamin D levels at diagnosis (median 36.0 nmol/l) (P=0.035). Harvey-Bradshaw Index (P=0.0001) and Simple Clinical Colitis Activity Index s...
