Decrease in Serum Vitamin D Level of Older Patients with Fatigue

Fatigue is characterized by reduced energy level, decreased muscle strength, and a variable degree of cognitive impairment. Recent evidences seem to link vitamin D deficiency to fatigue. The aim of this study was to assess and compare vitamin D status in a cohort of older subjects with and without fatigue. We recruited a total of 480 subjects, 240 patients with fatigue and 240 controls without fatigue, from the Cannizzaro Hospital of Catania (Italy). Fatigue severity was measured by the fatigue severity scale, whereas mental and physical fatigue were measured through the Wessely and Powell fatigue scale, respectively. We also measured several blood parameters and 25-OH vitamin D. Subjects with fatigue showed lower levels of vitamin D as compared with those without fatigue. Blood levels of parameters related to fatigue were normal in both groups of subjects, however, platelet, hemoglobin, hematocrit (p < 0.05), mean corpuscular volume, C-reactive protein (CRP), iron, vitamin B12, and folic acid (p < 0.001) were significantly higher in the fatigue group with respect to the control group. Moreover, compared to controls, patients showed higher scores in the physical (p < 0.001), mental (p < 0.001), and severity (p < 0.001) fatigue scales. Finally, vitamin D inversely correlated with fatigue severity (r = −0.428, p < 0.01), whereas creatine kinase and CRP levels did not correlate with vitamin D. In conclusion, our data showed a direct link between vitamin D and fatigue in older subjects, suggesting translational implications in the diagnosis and management of these patients.

Introduction The aim of this study was to compare serum vitamin D between fertile and infertile men in endemic area of vitamin D deficiency. The role of vitamin D in all aspects of human health has attracted a great interest. Vitamin D effect on female fertility and to a lesser extent in men is under investigation. Previous researchers have found meaningful positive relationship between semen quality and serum vitamin D level. However, in endemic area of vitamin D deficiency, this effect is under question. Methods Serum 25-OH-Vitamin D was compared between infertile male patients and fertile control group. Infertile cases were from patients of our infertility clinic and fertile controls from healthy cases with at least one child below 5 years of age. SPSS version 19 was used for statistical analysis (Kolmogorov-Smirnov test and Mann-Whitney test). Results Between 116 fertile and 114 infertile men who entered the study, serum level of 20 was a critical point, which patients with upper serum level had significantly better spermogram. In addition to it, even in vitamin D deficient patients and controls, fertile controls had higher serum vitamin D. Conclusions There is a positive correlation between serum level of vitamin D and spermogram quality, even in vitamin D deficient areas. Fertile people have a higher level of serum vitamin D in comparison to infertile patient in aforementioned areas.

Abstract Background Autism is a group of neurodevelopmental disabilities with various genetic and environmental risk factors. Vitamin D is an important neurosteroid hormone which can affect brain development and function, but research on its use in treating autism has been limited. Objectives The current study aimed at assessing the level of 25 OH vit D3level in a group of autistic infants and children compared to controls and correlating it with the severity of autistic manifestations and evaluation of the role of therapeutic doses of vitamin D on the severity of autistic manifestations. Methodology Thirty autistic Egyptian children (group I) and 30 clinically healthy age and sex matched controls were enrolled (group II). Therapeutic doses of vitamin D were given for autistic children who showed insufficient levels of 25 OH cholecalceferol for a period of 4-6 weeks followed by maintenance doses for another 6 weeks. Psychometric and laboratory evaluation for this group was done thrice: at the onset of study, at 6 week after enrollment in the study, and at 12 weeks after that enrollment. Results Serum vitamin D level was substantially reduced in patients with ASD in comparison to control group, and on the other hand, 25 (OH) vitamin D level was significantly negatively correlated with ATEC score and Total CARS score. Autistic children who received vitamin D3 treatment had significant improvement of CARS and ATEC scores. Conclusion vitamin D supplementation significantly improved the outcome of enrolled autistic children. It is recommended to follow up our studied sample to check the consolidation of improvement for how long it will be needed.

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).

AbstractTo investigate the mechanism of 25 hydroxyvitamin D (25(OH)D) deficiency in children with biliary atresia (BA) and its effect on liver fibrosis. The serum vitamin D and 25(OH)D, and expression of 25 hydroxylase (CYP2R1 and CYP27A1) in the liver of BA patients were detected and compared with those in the control group. We investigated the effect of differential expression of CYP2R1 in hepatocytes on the expression of genes related to liver fibrosis in primary hepatic stellate cells (HSCs) of BA and animal models of cholestasis. The ratio of 25(OH)D/vitamin D in the BA group was significantly lower than that in the control group. The mRNA and protein expression of CYP2R1 and CYP27A1 in liver tissue of the BA group was significantly lower than that in the control group. Exogenous active vitamin D (calcitriol) inhibited the proliferation and migration of primary HSCs isolated from BA patients, and reduced the expression of fibrosis-related genes in vitro. Downregulation of expression of CYP2R1 in hepatocytes increased expression of transforming growth factor (TGF)-β1, collagen (Col)-1α1 and tissue inhibitor of metalloproteinase (TIMP)-1, and decreased the expression of matrix metalloproteinase (MMP)-2 in cocultured primary HSCs of BA. Upregulation of expression of CYP2R1 in mice with bile duct ligation significantly increased the level of 25(OH)D, decreased the expression of TGF-β1, Col-1α1 and TIMP-1, and increased the expression of MMP-2. Children with BA have impaired vitamin D activation due to CYP2R1 deficiency. The dysactivation of vitamin D can promote the proliferation and activation of HSCs and participate in the development of hepatic fibrosis in BA.

In this study we aimed to assess vitamin D metabolism in patients with Cushing’s disease (CD) compared to healthy individuals in the setting of bolus cholecalciferol treatment. The study group included 30 adults with active CD and the control group included 30 apparently healthy adults with similar age, sex and BMI. All participants received a single dose (150,000 IU) of cholecalciferol aqueous solution orally. Laboratory assessments including serum vitamin D metabolites (25(OH)D3, 25(OH)D2, 1,25(OH)2D3, 3-epi-25(OH)D3 and 24,25(OH)2D3), free 25(OH)D, vitamin D-binding protein (DBP) and parathyroid hormone (PTH) as well as serum and urine biochemical parameters were performed before the intake and on Days 1, 3 and 7 after the administration. All data were analyzed with non-parametric statistics. Patients with CD had similar to healthy controls 25(OH)D3 levels (p > 0.05) and higher 25(OH)D3/24,25(OH)2D3 ratios (p < 0.05) throughout the study. They also had lower baseline free 25(OH)D levels (p < 0.05) despite similar DBP levels (p > 0.05) and lower albumin levels (p < 0.05); 24-h urinary free cortisol showed significant correlation with baseline 25(OH)D3/24,25(OH)2D3 ratio (r = 0.36, p < 0.05). The increase in 25(OH)D3 after cholecalciferol intake was similar in obese and non-obese states and lacked correlation with BMI (p > 0.05) among patients with CD, as opposed to the control group. Overall, patients with CD have a consistently lower 25(OH)D3/24,25(OH)2D3 ratio, which is indicative of a decrease in 24-hydroxylase activity. This altered activity of the principal vitamin D catabolism might influence the effectiveness of cholecalciferol treatment. The observed difference in baseline free 25(OH)D levels is not entirely clear and requires further study.
