Abstract Purpose: To assess the effect of oral vitamin D3 supplementation in dry eye after femtosecond laser-assisted in situ keratomileusis (FS-LASIK).Setting: Liuzhou Worker’s Hospital.Design: This prospective study included 90 patients selected between January and December in 2019, who underwent fs-lasik operation in our hospital and had obvious symptoms indicating dry eyes one month after operation. The subjects were randomly divided into two groups: the experimental group (n = 45) received vitamin D3 2000 IU / D continuously for 12 weeks; the control group (n = 45) did not take vitamin D3 orally. Ocular surface disease index（OSDI）, tear breakup time（TBUT）and Schirmer’s Test I were evaluated pre-medication and 1,3,6 months after treatment. Serum vitamin D level, and the mean concentration of cytokine IL-6, IL-17, IL-23 in tears were also measured. Results: One month after treatment, the mean OSDI score of the experimental group (11.67 ± 8.53) was significantly lower than that of the control group (23.82 ± 13.22) (P = 0.007). TBUT (10.71±1.02s) and Schirmer I (9.36±0.40mm) of the experimental group were higher than those of the control group (7.49±1.29 s and 7.51±0.44 mm). The OSDI (10.25 ± 5.49), TBUT (10.75±1.09 seconds) and Schirmer I test value (11.34±0.39 mm) of the experimental group were significantly lower than those of the control group (20.22±6.23, 8.36±1.23， 8.12±0.50) at 3 months after treatment. There were significant differences in OSDI, TBUT (P ＜ 0.05) and Schirmer I test value between the two groups at 6 months after treatment. Serum vitamin D3 level was negatively correlated with OSDI score (r=-0.90；P=0.00), and positively correlated with Schirmer I test (r=0.88；P=0.00), TBUT score (r=0.89；P=0.00) and TMH (r=0.80；P=0.00). IL-17 level was shown to be significantly correlated with TBUT (r=-0.25, P=0.014) and Schirmer I test (r=-0.21, P=0.018). IL-6 level was significantly correlated with OSDI (R=0.18, P = 0.020) and TBUT (R=0.20, P = 0.019).

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

The Impact

Diabetes is one of the commonest chronic diseases worldwide. Vitamin D deficiency showed to be increasing, and have a potential role in autoimmune diseases among which in type 1 diabetes. The aim The aim of the study was to assess the impact of oral vitamin D supplementation on blood glucose (HbA1C) in T1DM patients and to find out the role of vitamin D as a biomarker for follow of T1DM patients compared to HbA1C. Subjects and methods: A randomized interventional clinical study was designed. The study enrolled 60 children patients with T1DM. Only 45 children continued to the end of study. Initial (pre-intake) assessment included history taking, clinical examination, and measurement of serum 25-OH vitamin D3 and serum HbA1C. These children received oral vitamin D supplements for 3 months then post-intake assessment were done again. Results: The study showed that serum vitamin D was deficient among Egyptian children and adolescents with T1DM (mean 11.4±3.4 ng/ml). , 53.33% of the patients had vitamin D deficiency with a 35.6% had insufficiency and 11.11% were VD sufficient. Patients received oral vitamin D supplementation for 3 months after which marked improvement in the levels of serum vitamin D levels and HA1C, 87.5% and 86.5% respectively.

Introduction: Dry eye syndrome [DES] is one of the commonest ocular disorders characterized by tear film instability, visual discomfort & disturbance with ocular surface inflammation potentially leading to damage to the ocular surface. Serum Vitamin-D deficiency has been reported to be associated with DES. Aim: To determine the Serum 25-hydroxy-vitamin-D levels in patients diagnosed as having DES. Methods: We conducted a prospective observational study and included in our study, serum vitamin D levels of the first 40 patients over the age of 18 years presenting with signs and symptoms and later diagnosed to have DES [confirmed with ocular surface disease index-OSDI questionnaire, Schirmer I test, kerato-epitheliopathy examination and tear-film breakup time-[TBUT] were analysed. Results: Schirmer's I test, interpreted as mild [11-15mm/5min], moderate [6-10 mm/5 min] and severe [<5mm/5min] had 8, 17 and 15 patients, respectively, with a mean value of 8 mm/5 min Schirmers I test. The minimum and maximum of Fluorescein TBUT measured in seconds was 4 and 10 seconds, respectively, with a mean of 6.2 seconds. Twenty four of our test subjects were found to have deficient Serum Vit 25[OH] D levels, nine had insufficient levels and seven had normal levels. Conclusion: Vitamin D deficiency is prevalent in patient having DES.

Coronavirus disease (COVID-19) is a new viral illness that affects not only the respiratory system but also leads to multiorgan involvement. Till now, no curative treatment is available; prevention is the only way to reduce the number of infected cases. Low serum level of vitamin D has been implicated in increased susceptibility to coronavirus infection and disease severity. However, there is no conclusive evidence as regards the role of vitamin D in COVID-19 infection and outcome. This study aimed to evaluate the serum level of Vit D in patients with COVID-19 and highlights its prognostic significance. A total of 109 COVID-19 patients' medical records were selected and retrospectively analyzed from Ohoud Hospital in Medina. Data collection was done in the period between 1/4/2020 and 22/2/2021 followed by statistical analysis. The median age for COVID-19 patients was 54 years old. The level of Vit-D was low in patients with COVID-19 with a median of 15.2 ng/ml. Serum ferritin was high in all COVID-19 patients with a median of 720.9 ng/ml. There was a significantly higher rate of developing severe forms of COVID-19 in males compared to females, P-value < 0.001. Serum vitamin D level was significantly lower in patients with COVID-19 compared to control with P-value < 0.001. More reduction in Vit-D level was detected in the severe form of COVID-19 (P-value 0.042). There were significantly lower levels of vitamin D and higher levels of ferritin in the server covid-19 cases, P-values of 0.018 and 0.001, respectively. Low serum Vitamin-D level was significantly associated with a higher risk of COVID-19 infection and a more severe form of the disease that may end by death. Vitamin D supplementation will provide a sufficient serum level of the vitamin that can prevent infection and or minimize COVID-19 severity. Keywords: COVID-19, vitamin D deficiency.

Vitamin D deficiency is common in women with polycystic ovarian syndrome. Vitamin D plays an important physiologic role in reproductive functions of ovarian follicular development and luteinization through altering anti-müllerian hormone signaling, follicular stimulating hormone activity and progesterone production in human granulose cells. Vitamin D is precipitated in adipose fat tissues, making it notable to be used for the body as a result; obese people with high body mass index are already highly expected to have low levels of serum vitamin D.
