cholecalciferol and Liver-Cirrhosis

Vitamin D deficiency is often reported in people with chronic liver diseases. Therefore, improving vitamin D status could have a beneficial effect on people with chronic liver diseases.. To assess the beneficial and harmful effects of vitamin D supplementation in people with chronic liver diseases.. We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Science Citation Index Expanded, and Conference Proceedings Citation Index - Science. We also searched databases of ongoing trials and the World Health Organization International Clinical Trials Registry Platform. We scanned bibliographies of relevant publications and asked experts and pharmaceutical companies for additional trials. All searches were up to January 2017.. Randomised clinical trials that compared vitamin D at any dose, duration, and route of administration versus placebo or no intervention in adults with chronic liver diseases. Vitamin D could have been administered as supplemental vitamin D (vitamin D. We used standard methodological procedures expected by The Cochrane Collaboration. We contacted authors of the trials to ask for missing information. We conducted random-effects and fixed-effect meta-analyses. For dichotomous outcomes, we calculated risk ratios (RRs), and for continuous outcomes, we calculated mean differences (MD), both with 95% confidence intervals (CI) and Trial Sequential Analyses-adjusted CIs. We calculated Peto odds ratio (OR) for rare events. We considered risk of bias in domains to assess the risk of systematic errors. We conducted Trial Sequential Analyses to control the risk of random errors. We assessed the quality of the evidence with GRADE.. We included 15 randomised clinical trials with 1034 participants randomised. All trials had a parallel group design. Nine trials were conducted in high-income countries and six trials in middle-income countries. All trials were at high risk of bias. Six trials included participants with chronic hepatitis C, four trials included participants with liver cirrhosis, four trials included participants with non-alcoholic fatty liver disease, and one trial included liver transplant recipients. All included trials reported the baseline vitamin D status of participants. Participants in six trials had baseline 25-hydroxyvitamin D levels at or above vitamin D adequacy (20 ng/mL), while participants in the remaining nine trials were vitamin D insufficient (less than 20 ng/mL). All trials administered vitamin D orally. Mean duration of vitamin D supplementation was 0.5 years and follow-up was 0.6 years. Eleven trials (831 participants; 40% women; mean age 52 years) tested vitamin D. We are uncertain as to whether vitamin D supplements in the form of vitamin D

Middle East Respiratory Syndrome (MERS) is a novel respiratory illness firstly reported in Saudi Arabia in 2012. It is caused by a new corona virus, called MERS corona virus (MERS-CoV). Most people who have MERS-CoV infection developed severe acute respiratory illness.. This work is done to determine the clinical characteristics and the outcome of intensive care unit (ICU) admitted patients with confirmed MERS-CoV infection.. This study included 32 laboratory confirmed MERS corona virus infected patients who were admitted into ICU. It included 20 (62.50%) males and 12 (37.50%) females. The mean age was 43.99 ± 13.03 years. Diagnosis was done by real-time reverse transcription polymerase chain reaction (rRT-PCR) test for corona virus on throat swab, sputum, tracheal aspirate, or bronchoalveolar lavage specimens. Clinical characteristics, co-morbidities and outcome were reported for all subjects.. Most MERS corona patients present with fever, cough, dyspnea, sore throat, runny nose and sputum. The presence of abdominal symptoms may indicate bad prognosis. Prolonged duration of symptoms before patients' hospitalization, prolonged duration of mechanical ventilation and hospital stay, bilateral radiological pulmonary infiltrates, and hypoxemic respiratory failure were found to be strong predictors of mortality in such patients. Also, old age, current smoking, smoking severity, presence of associated co-morbidities like obesity, diabetes mellitus, chronic heart diseases, COPD, malignancy, renal failure, renal transplantation and liver cirrhosis are associated with a poor outcome of ICU admitted MERS corona virus infected patients.. Plasma HO-1, ferritin, p21, and NQO1 were all elevated at baseline in CKD participants. Plasma HO-1 and urine NQO1 levels each inversely correlated with eGFR (. SnPP can be safely administered and, after its injection, the resulting changes in plasma HO-1, NQO1, ferritin, and p21 concentrations can provide information as to antioxidant gene responsiveness/reserves in subjects with and without kidney disease.. A Study with RBT-1, in Healthy Volunteers and Subjects with Stage 3-4 Chronic Kidney Disease, NCT0363002 and NCT03893799.. HFNC did not significantly modify work of breathing in healthy subjects. However, a significant reduction in the minute volume was achieved, capillary [Formula: see text] remaining constant, which suggests a reduction in dead-space ventilation with flows > 20 L/min. (ClinicalTrials.gov registration NCT02495675).. 3 组患者手术时间、术中显性失血量及术后 1 周血红蛋白下降量比较差异均无统计学意义（. 对于肥胖和超重的膝关节单间室骨关节炎患者，采用 UKA 术后可获满意短中期疗效，远期疗效尚需进一步随访观察。.. Decreased muscle strength was identified at both time points in patients with hEDS/HSD. The evolution of most muscle strength parameters over time did not significantly differ between groups. Future studies should focus on the effectiveness of different types of muscle training strategies in hEDS/HSD patients.. These findings support previous adverse findings of e-cigarette exposure on neurodevelopment in a mouse model and provide substantial evidence of persistent adverse behavioral and neuroimmunological consequences to adult offspring following maternal e-cigarette exposure during pregnancy. https://doi.org/10.1289/EHP6067.. This RCT directly compares a neoadjuvant chemotherapy regimen with a standard CROSS regimen in terms of overall survival for patients with locally advanced ESCC. The results of this RCT will provide an answer for the controversy regarding the survival benefits between the two treatment strategies.. NCT04138212, date of registration: October 24, 2019.. Results of current investigation indicated that milk type and post fermentation cooling patterns had a pronounced effect on antioxidant characteristics, fatty acid profile, lipid oxidation and textural characteristics of yoghurt. Buffalo milk based yoghurt had more fat, protein, higher antioxidant capacity and vitamin content. Antioxidant and sensory characteristics of T. If milk is exposed to excessive amounts of light, Vitamins B. The two concentration of ZnO nanoparticles in the ambient air produced two different outcomes. The lower concentration resulted in significant increases in Zn content of the liver while the higher concentration significantly increased Zn in the lungs (p < 0.05). Additionally, at the lower concentration, Zn content was found to be lower in brain tissue (p < 0.05). Using TEM/EDX we detected ZnO nanoparticles inside the cells in the lungs, kidney and liver. Inhaling ZnO NP at the higher concentration increased the levels of mRNA of the following genes in the lungs: Mt2 (2.56 fold), Slc30a1 (1.52 fold) and Slc30a5 (2.34 fold). At the lower ZnO nanoparticle concentration, only Slc30a7 mRNA levels in the lungs were up (1.74 fold). Thus the two air concentrations of ZnO nanoparticles produced distinct effects on the expression of the Zn-homeostasis related genes.. Until adverse health effects of ZnO nanoparticles deposited in organs such as lungs are further investigated and/or ruled out, the exposure to ZnO nanoparticles in aerosols should be avoided or minimised.

Bariatric patients often suffer from vitamin D deficiency (VDD), and both, morbid obesity and VDD, are related to non-alcoholic fatty liver disease. However, limited data are available regarding best strategies for treating VDD, particularly, in bariatric patients undergoing omega-loop gastric bypass (OLGB). Therefore, we examined the efficacy and safety of a forced vitamin D dosing regimen and intervention effects in liver fibrotic patients.. Compared with control group, higher increase of 25(OH)D (67.9 (21.1) vs. 55.7 nmol/L (21.1); p = 0.049) with lower prevalence of secondary hyperparathyroidism (10 vs. 24 %; p = 0.045) was observed in intervention group. No (serious) adverse events related to study medication were found. The loading dose regimen was more effective in increasing 25(OH)D in patients with significant liver fibrosis while this was not the case for conventional supplementation (placebo with maintenance dose) (71.5 (20.5) vs. 22.5 nmol/L (13.8); p = 0.022; n = 14).. Our findings indicate that a high vitamin D

The current standard of care therapy (SOC) for chronic HCV is pegylated interferon/ribavirin (Peg-IFN/RBV). Many reports showed the possible role of vitamin D supplementation in augmenting the response to SOC. The aim of this study was to assess the role of vitamin D supplementation on the response to treatment in chronic HCV genotype 4 patients. One hundred and one chronic HCV patients were classified into two groups (Group 1): 51 patients received the SOC therapy consisting of Peg-interferon alfa-2b plus ribavirin, (Group 2): 50 patients received the SOC therapy+vitamin D3 (Cholecalciferol) in a dose of 15,000 IU/week during the treatment course. Vitamin D deficiency was found in 95% of patients. No correlation was found between vitamin D levels and stage of fibrosis in the whole population. Vitamin D supplementation had no positive impact on treatment outcome where sustained virological response (SVR) was achieved in 51.2% in group 2 and 71.4% in group 1 by per-protocol analysis and in 44% in group 2 and in 68.6% in group 1 by intention to treat analysis (P value 0.22 and 0.220 respectively). Despite its role in other genotypes, vitamin D supplementation has no significant impact on SVR in HCV Genotype 4 patient. No correlation was found between vitamin D levels and stage of liver fibrosis.

Pathological bacterial translocation from the disrupted intestinal barrier leads to substantial complications and mortality in liver cirrhosis. Vitamin D is reported as beneficial to gut barriers in some animal models. However, its effect on cirrhotic bacterial translocation is unknown. The authors aim to investigate the effects of calcitriol on bacterial translocation in cirrhotic rats.. Cirrhotic rats are administrated with a 2-week course of active vitamin D. Calcitriol treatment attenuates intestinal permeability, reduces bacterial translocation, and enriches potentially beneficial gut microbiota in cirrhotic rats that may enable it as a potential therapeutic agent to prevent cirrhotic complications.

Type 2 diabetes is clinically associated with progressive necroinflammation and fibrosis in nonalcoholic steatohepatitis (NASH). Advanced glycation end-products (AGEs) accumulate during prolonged hyperglycemia, but the mechanistic pathways that lead to accelerated liver fibrosis have not been well defined. In this study, we show that the AGEs clearance receptor AGER1 was downregulated in patients with NASH and diabetes and in our NASH models, whereas the proinflammatory receptor RAGE was induced. These findings were associated with necroinflammatory, fibrogenic, and pro-oxidant activity via the NADPH oxidase 4. Inhibition of AGEs or RAGE deletion in hepatocytes in vivo reversed these effects. We demonstrate that dysregulation of NRF2 by neddylation of cullin 3 was linked to AGER1 downregulation and that induction of NRF2 using an adeno-associated virus-mediated approach in hepatocytes in vivo reversed AGER1 downregulation, lowered the level of AGEs, and improved proinflammatory and fibrogenic responses in mice on a high AGEs diet. In patients with NASH and diabetes or insulin resistance, low AGER1 levels were associated with hepatocyte ballooning degeneration and ductular reaction. Collectively, prolonged exposure to AGEs in the liver promotes an AGER1/RAGE imbalance and consequent redox, inflammatory, and fibrogenic activity in NASH.

Liver cholestasis is a complex disease of broad etiologies. Hedgehog (Hh) signaling has been shown to play a pivotal role in modulating liver repair post cholestatic liver injury. We here investigated the role of vitamin D in experimental liver cholestasis induced by bile-duct ligation (BDL) in rats. Male Sprague Dawley rats underwent BDL surgery and two weeks post-surgery; vitamin D was administered daily for two weeks. Serum markers of hepatocellular integrity were measured and fibrosis was detected by measuring α-SMA and hepatic TGF-β1 as well as hepatic collagen content. Hh signaling was evaluated by measuring Smo and Gli1 levels. Histopathological examination of hepatic tissue was performed. Vitamin D alleviated obstructive cholestatic damage as illustrated by total bilirubin as well as gamma glutamyl transferase (γ-GT) serum levels. It also alleviated hepatocellular damage as suggested by reducing elevated serum aminotransferases induced by BDL. Antifibrotic activity of vitamin D was confirmed by decrease in mRNA and protein expression of α-SMA, as well as collagen content in hepatic tissue. Furthermore, vitamin D suppressed BDL-induced elevated hepatic TGF-β1 mRNA and protein levels. BDL activated Hh signaling and upregulated its upstream component smoothened (Smo) and downstream target gene Gli1. Treatment with vitamin D reduced Smo mRNA levels and suppressed hepatic Gli1 mRNA and protein levels. Molecular docking of vitamin D to Smo revealed that vitamin D binds similarly to its endogenous cholesterol ligand and blocks its activation. These results demonstrate that vitamin D mitigated cholestatic liver injury through inhibiting Hh signaling.

BACKGROUND The aim of this study was to study the effects of 1-alpha,25-dihydroxy-cholecalcifero (1,25(OH)2D3) on liver fibrosis and the generation of Th17 cells in vivo and in vitro. MATERIAL AND METHODS Thirty C57 mice were randomly divided into control, model, and treatment groups. Hepatic fibrosis was induced by subcutaneous injection of CCl4. Liver fibrosis condition was evaluated through pathological inspection and blood biochemical examination of liver function. Immunohistochemical assays were used to detect the expression of α-SMA, TGF-β, and collagen I to observe hepatic stellate cell activation level. Flow cytometry, ELISA, and RT-PCR were performed to explore the association between 1,25(OH)2D3 and Th17 cell differentiation. RESULTS Collagen I, TGF-β, and α-SMA were decreased after 1,25(OH)2D3 treatment. Consistently, RORγt mRNA and the rate of Th17 cells was significantly reduced after 1,25(OH)2D3 treatment. In vitro, the proportion of Th17 cells was also obviously reduced in the 1,25(OH)2D3 group, and mRNA levels of IL-17A, IL-22, RORγt, and RORa were significantly decrease in the 1,25(OH)2D3 group compared to the control group. CONCLUSIONS Treatment with 1,25(OH)2D3 can alleviate the damage caused by liver fibrosis. Experiments in vivo and in vitro showed that 1,25(OH)2D3 treatment deceased the rates of Th1 and Th17 cells and increased the rate of Th2 cells. The level of IL-17A, IL-22 and IFN-γ were decreased, while the level of IL-4 was increased by the treatment of 1,25(OH)2D3.

It has been reported that the serum level of vitamin D3 (VitD3) could affect the natural course of chronic hepatitis C (CH-C) and the response to treatment with pegylated interferon (Peg-IFN) and ribavirin. Although several mechanisms for the favorable effects of VitD3 supplementation were reported, the total effect of VitD3 supplementation remains unclear. Previously, we reported that supplementation with 1(OH)VitD3 could enhance the Th1 response inducing not only a favorable immune response for viral eradication but also HCC control. Recently, the main treatment of CH-C should be direct acting antivirals (DAAs) without Peg-IFN. Peg-IFN is a strong immune-modulator. Therefore, an immunological analysis should be carried out to understand the effect of VitD3 after treatment of DAAs without Peg-IFN. The induction of a favorable immune response by adding VitD3 might be able to suppress the hepatocarcinogenesis after achieving SVR, especially in children and elderly patients with severe fibrosis lacking sufficient amounts of VitD3.

Recently, hepatic immaturity was cited as a possible reason for high levels of the C-3 epimer of 25-hydroxyvitamin (25(OH)D) in premature infants: however what role, if any, the liver plays in controlling epimer concentrations is unknown. This study assesses 3-epi-25-hydroxyvitamin D (3-epi-25(OH)D) levels during the course of cholecalciferol supplementation in adults with chronic liver diseases (CLD). Vitamin D metabolites were analyzed in 65 CLD patients with 25(OH)D <30 ng/mL who received 20 000 IU cholecalciferol/week for 6 months. The primary outcome assessed serum 25(OH)D and 3-epi-25(OH)D in response to supplementation. Corresponding values from 16 CLD patients with sufficient vitamin D levels receiving no supplementation were compared. The epimer was detected in all samples and at lower relative concentrations with lower vitamin D baseline status, i.e., severe vitamin D deficiency (<10 ng/mL) as compared with deficient (10-19.9 ng/mL), insufficient (20-29.9 ng/mL), or sufficient (≥30 ng/mL) vitamin D levels (2.4% vs. 4.8%, 5.2%, 5.8%, respectively; P < 0.001). Similar relative concentrations for 3-epi-25(OH)D, ranging from 4.3%-7.1% (absolute concentrations: 1.1-4.0 ng/mL; all P < 0.001), were obtained in response to cholecalciferol in all supplemented patients, regardless of inadequacy threshold. Epimer levels significantly decreased (P = 0.007) in unsupplemented patients, coinciding with decreasing serum 25(OH)D concentrations over time. No epimer differences between patients with (n = 17) or without (n = 48) cirrhosis were demonstrated. The 3-epi-25(OH)D was present in serum of all patients at comparable levels to those reported by others. Epimer levels increased linearly with increasing 25(OH)D levels after supplementation. However, no effect of cirrhosis on epimer concentrations was observed.

Vitamin D₃ improves portal hypertension (PH) through the activation of vitamin D receptor (VDR) and calcium-sensing receptor (CaSR) in cirrhotic rats. Propranolol is a non-selective β-blocker that is recommended for the treatment of PH. The present study aims to investigate the detail systemic and hepatic mechanisms of vitamin D₃ and propranolol, alone or in combination, in cirrhotic rats.. Common bile duct-ligated and thioacetamide cirrhotic rats were treated with vehicle, propranolol (30 mg/kg/day), vitamin D₃ (0.5 μg/100 g/day, twice weekly), or propranolol + vitamin D₃, separately.. Significantly, propranolol and vitamin D₃ produced a similar magnitude of reduction in portal venous pressure (PVP) in cirrhotic rats through different mechanisms: whereas propranolol decreased PVP by reducing splanchnic hyperemia and cardiac index, vitamin D₃ decreased PVP by decreasing intrahepatic resistance (IHR). However, propranolol + vitamin D₃ did not further decrease PVP in cirrhotic rats. Notably, a marked decrease in hepatic VDR and CaSR expressions was noted in cirrhotic human/rat livers compared with non-cirrhotic human/rat livers. In cirrhotic rats, vitamin D₃ administration decreasing IHR by inhibiting the renin-angiotensin system, hepatic oxidative stress, inflammation/fibrosis, angiotensin II (ANGII) production, CaSR-mediated ANGII hyperresponsiveness, ANGII-induced hepatic stellate cells contraction, and correcting hepatic endothelial dysfunction through upregulation of hepatic VDR, CaSR, and endothelial nitric oxide synthase expressions.. Chronic vitamin D₃ treatment alone results in comparative portal hypotensive effects as propranolol alone in cirrhotic rats with PH. Taken together, chronic vitamin D₃ administration was an ideal alternative strategy to effectively improve PH without unwanted systemic side-effects.

Aim of the present study was to investigate whether 1,25(OH)(2)D(3) (Vitamin D3) modulates T lymphocyte functions in patients transplanted for hepatitis C virus-related cirrhosis.. Sixteen patients and ten healthy subjects were investigated. T lymphocytes were activated in vitro in the presence or absence of Vitamin D3 and then the proliferative response and IFN-γ and TNF-α production were assessed.. Vitamin D3 potently reduced T-lymphocyte proliferation in a dose-related fashion. Similarly, FACS analysis and ELISA testing demonstrated that Vitamin D3 significantly decreased the response frequency and the response intensity of IFN-γ and TNF-α production in the whole CD3-positive T lymphocyte population as well as in "naive" CD4+ CD45RA+ and "memory" CD4+ CD45RO+ T lymphocyte subsets. The inhibitory effect of Vitamin D3 on T-cell proliferation and cytokine production was not different between patients and controls. No toxic effects were exerted by Vitamin D3 even at the higher concentration used (10nM). Finally, no statistically significant correlation was found between 25(OH)D serum levels and the proliferative response or cytokine production of T lymphocytes from transplanted patients.. This study demonstrates that in patients transplanted for hepatitis C virus-related cirrhosis Vitamin D3 modulates T lymphocyte activation, and provides a rationale for the evaluation of this compound as an immunosuppressive agent in liver-transplanted patients.

To investigate osteodystrophy in liver cirrhosis, 99Tcm MDP (methylene diphosphonate) bone scintigraphy was performed on 36 patients with liver cirrhosis. Abnormal lesions were detected in 17 out of 36 scans (47.2%). On the other hand, areas of increased uptake were uncommon in patients with chronic active hepatitis (1/11 cases). Plasma vitamin D3 fractions [25(OH)D3, 24.25(OH)2D3 and 1.25(OH)2D3] were decreased. Statistically significant depletion of 1.25(OH)2D3 was observed in cases with positive bone scintigraphy. 1 alpha(OH)D3 (1-2 micrograms/day) was administered for 6 months to nine patients having abnormal bone scans. Six of them showed improvement without any apparent side-effects. We conclude that hepatic cirrhotic osteodystrophy can be diagnosed positively by 99Tcm MDP bone scintigraphy and can be treated accordingly.

The response to vitamin D3 (D3) was studied in a model of micronodular cirrhosis induced by CCl4. The uptake and C-25 hydroxylation of D3 were then studied in isolated-perfused liver preparations. CCl4-treated rats had a significantly lower fractional hepatic D3 uptake than controls; they also had lower 25-hydroxyvitamin D3 (25(OH)D3) concentrations in both liver and perfusate following 150 min of perfusion. CCl4 induced a wide spectrum of hepatic morphologic changes ranging from mild to large collagen infiltration, but micronodular cirrhosis was present in more than 90% of the animals. Histomorphometric analysis of the liver indicated an overall highly significant increase in the volume density (Vv) of collagen infiltration, and a reduction in the Vv normal hepatocytes following CCl4. Linear relationships were also observed between the Vv normal hepatocytes and the liver, perfusate, and total 25(OH)D3, while the 25(OH)D3 production decreased in a logarithmic fashion as the collagen infiltration of the liver parenchyma increased. These data show that the overall production of 25(OH)D3 is decreased in micronodular cirrhosis; they also indicate, however, that the D3-25 hydroxylase seems to stay unimpaired in the remaining hepatocytes of the diseased liver, and that the Vv normal hepatocytes constitute one of the major determinants of the 25(OH)D3 production by the cirrhotic rat liver.

Vitamin D metabolism was investigated in 10 patients with cirrhosis. Mean plasma 25 hydroxycholecalciferol (25 OHD) centration in alcoholic cirrhosis was lower than in controls but the difference was not significant. In three patients restudied after the summer, plasma 25 OHD had risen. In contrast to the finding in normal subjects, the half-life of intravenously administered 3H cholecalciferol was short in cirrhotics and showed no correlation with plasma 25 OHD. Furthermore, the appearance of 3H 25 OHD from 3H cholecalciferol was reduced compared to the control group four hours after injection. Increased rate of metabolism of cholecalciferol and deficient production of 25 ohd contribute to vitamin D deficiency in liver disease.

To assess the role of hepatic function and alcohol on vitamin D metabolism, serum 25-hydroxyvitamin D (25-OHD) levels were measured in 20 healthy nonalcoholic control subjects, 31 "inactive" cirrhotics whose alcoholism was in remission, 8 alcoholic cirrhotics, and 15 alcoholics with normal liver function. Cirrhosis but not alcoholism, was assoicated with low serum 25-OHD levels. The aminopyrine breath test (ABT) was performed because aminopyrine, like vitamin D3, is metabolized by hepatic microsomes; the ABT correlated highly (r = 0.74, rho less than 0.01) with serum 25-OHD in the inactive cirrhotics. After an intravenous injection of 120 mug vitamin D3, serum 25-OHD rose significantly within 24 hr in 6 healthy controls and 2 patients with celiac disease but not in 6 inactive cirrhotics. The data suggest impaired 25-hydroxylation of vitamin-D impaired in patients with cirrhosis, related predominantly to the degree of hepatic dysfunction.

Vitamin D(3)-(3)H has been administered intravenously to seven normal subjects, three patients with biliary fistulas, and four patients with cirrhosis. Plasma D(3)-(3)H half-times normally ranged from 20 to 30 hours. in vivo evidence that a metabolic transformation of vitamin D occurs was obtained, and a polar biologically active vitamin D metabolite was isolated from plasma. Urinary radioactivity averaged 2.4% of the administered dose for the 48-hour period after infusion, and all the excreted radioactivity represented chemically altered metabolites of vitamin D. The metabolites in urine were mainly water-soluble, with 26% in conjugated form. From 3 to 6% of the injected radioactivity was excreted in the bile of subjects with T-tube drainage and 5% in the feces of patients having no T-tube. The pattern of fecal and biliary radioactivity suggested that the passage of vitamin D and its metabolites from bile into the intestine represents an essential stage for the fecal excretion of vitamin D metabolites in man. Abnormally slow plasma disappearance of vitamin D(3)-(3)H in patients with cirrhosis was associated with a significant decrease in the quantity and rate of glucuronide metabolite excretion in the urine.
