Vitamin D deficiency is common in patients with chronic liver disease, including chronic hepatitis C (CHC). However, the interplay between serum 25-hydroxy-vitamin-D (25-OH-D) and health-related-quality-of-life (HRQoL) in CHC subjects has never been investigated. The study aimed to analyze the relationship between vitamin D deficiency and HRQoL in CHC patients. One-hundred-fifty-five consecutive CHC patients completed the Health-Survey-Short-Form-36 (SF-36) and their serum 25-OH-D levels were evaluated. Vitamin D deficiency was defined as a 25-OH-D level lower than 20 ng/mL.
We identified 53 patients (34.2%) with vitamin D deficiency, who showed a mean 25-OH-D serum level of 12.5 ± 3.7 ng/mL.
Vitamin D deficient patients had significantly higher liver stiffness values compared to those with normal levels (20.8 ± 14 vs 14.9 ± 9.7 KPa, p=0.003). In a multivariate linear regression analysis, vitamin D deficiency was independently associated with a lower SF-36 physical-component summary score (p=0.034) and SF-36 mental-component summary score (p=0.042) after controlling for age, gender and liver stiffness.
Specifically, vitamin D deficiency was associated with 3 out of 4 physical domains of the SF-36 [physical-function (p=0.016), role-physical (p=0.016) and general-health (p=0.002)] and 3 out of 4 mental domains [vitality (p=0.020), role-emotional (p=0.005) and mental-health (p=0.025)].
In conclusion, the present study provides novel evidence demonstrating that vitamin D deficiency can contribute to a decreased physical and mental HRQoL in CHC patients. Given that serum vitamin D levels are easy to evaluate and deficiency treatment is simple and inexpensive, clinicians should be aware of the potential multiple benefits of vitamin D supplementation in CHC patients.

Hepatitis-C associated with low micronutrients - such as Vitamin D - June 2019

The Role of Micronutrients in the Infection and Subsequent Response to Hepatitis C Virus
 Download the PDF from Vitamin D Life


BACKGROUND:
Although a contributory role of vitamin D levels for the development of chronic hepatitis C has been suggested, the efficacy of vitamin D supplementation in combination with conventional antiviral therapy consisting of pegylated interferon-α (Peg-IFN-α) injection and oral ribavirin (RBV) remains unclear. We investigated its efficacy in the treatment of chronic hepatitis C via a meta-analysis of randomised controlled trials.
METHODS:
We searched PubMed, EMBASE, the Cochrane Library, ClinicalTrials.gov and the bibliographies of relevant articles to locate additional publications in September 2016. Three evaluators independently reviewed and selected eligible studies based on predetermined selection criteria.
RESULTS:
Of 522 articles meeting our initial criteria, a total of seven open-label, randomised controlled trials involving 548 participants, were included in the final analysis. Vitamin D supplementation in combination with Peg-IFN-α injection and oral RBV significantly increased the rate of viral response for hepatitis C at 24 weeks after treatment in a random-effects meta-analysis (relative risk = 1.30; 95% confidence interval = 1.04-1.62; I2 = 75.9%). Also, its significant efficacy was observed in patients with hepatitis C virus genotype 1, which is known to be refractory to antiviral therapy.
CONCLUSIONS:
In summary, we observed that additional use of vitamin D has a positive effect on sustained viral response rates of patients with chronic hepatitis C infection. However, we cannot establish the efficacy because of substantial heterogeneity, a small sample size and a low methodological quality.

Vitamin D Life Summary

HCV-RNA negative

Week 12
2000 IU Vitamin D + conventional94%
Conventional treatment 48%

AIM:
To determine whether adding vitamin D, a potent immunomodulator, improves the hepatitis C virus (HCV) response to antiviral therapy.
METHODS:
Seventy-two consecutive patients with chronic HCV genotype 1 were randomized into two groups: the treatment group (n = 36, 50% male, mean age 47 ± 11 years) received Peg-α-2b interferon (1.5 μg/kg per week) plus ribavirin (1000-1200 mg/d) together with vitamin D3 (2000 IU/d, target serum level > 32 ng/mL), and the control group (n = 36, 60% male, mean age 49 ± 7 years) received identical therapy without vitamin D. HCV-RNA was assessed by real-time polymerase chain reaction (sensitivity, 10 IU/mL). The sustained virologic response (SVR) was defined as undetectable HCV-RNA at 24 wk post-treatment.
RESULTS:
Clinical characteristics were similar in both groups. The treatment group had a higher mean body mass index (27 ± 4 kg/m² vs 24 ± 3 kg/m²; P < 0.01), viral load (50% vs 42%, P < 0.01), and fibrosis score (> F2: 42% vs 19%, P < 0.001) than the controls. At week 4, 16 (44%) treated patients and 6 (17%) controls were HCV-RNA negative (P < 0.001). At week 12, 34 (94%) treated patients and 17 (48%) controls were HCV-RNA negative (P < 0.001). At 24 wk post-treatment (SVR), 31 (86%) treated patients and 15 (42%) controls were HCV-RNA negative (P < 0.001). Viral load, advanced fibrosis and vitamin D supplementation were strongly and independently associated with SVR (multivariate analysis). Adverse events were mild and typical of Peg-α-2b/ribavirin.
CONCLUSION:
Adding vitamin D to conventional Peg-α-2b/ribavirin therapy for treatment-naïve patients with chronic HCV genotype 1 infection significantly improves the viral response.

The Interplay between Zinc, Vitamin D and, IL-17 in Patients with Chronic Hepatitis C Liver Disease - 2015

J Immunol Res. 2015;2015:846348. doi: 10.1155/2015/846348. Epub 2015 Oct 4.

OBJECTIVES:
To assess zinc (Zn) and vitamin D (Vit. D) status in chronic Hepatitis C virus- (HCV) infected patients and their relationship to interleukin- (IL-) 17 and disease severity and then investigate whether Zn and Vit. D3 modulate IL-17 expression in chronic HCV patients.
METHODS:
Seventy patients and fifty healthy subjects were investigated. Serum levels of Zn, Vit. D, and IL-17 were assessed in the patients group and subgroups. Patients lymphocytes were activated in vitro in the presence or absence of Zn or Vit. D3 and then intracellular IL-17 production was assessed using flow cytometry.
RESULTS:
Zn and Vit. D were significantly decreased in HCV patients. Increasing disease severity leads to more reduction in Zn level opposed by increasing IL-17 level. Zn potently reduced IL-17 production in a dose-related fashion; however it did not exert any toxic effects. Although Vit. D apparently increases IL17 expression, it is unclear whether it is due to its toxic effect on cell count or lack of definite association between Vit. D and both IL-17 and disease severity.
CONCLUSIONS:
This study demonstrates that Zn modulates IL-17 expression and provides a rationale for evaluating this compound as a supplementary agent in the treatment of chronic HCV.

Vitamin D status and viral response to therapy in hepatitis C infected children - 2015

World J Gastroenterol. 2015 Jan 28;21(4):1284-91. doi: 10.3748/wjg.v21.i4.1284.
Eltayeb AA1, Abdou MA1, Abdel-aal AM1, Othman MH1.

AIM:
To study the frequency of vitamin D deficiency in patients with hepatitis C virus (HCV) infection and to evaluate the role of vitamin D supplementation in improving antiviral therapy.
METHODS:
Sixty-six children aged from 7-14 years (mean ± SD, 11.17±2.293) diagnosed with HCV infection were matched to 28 healthy controls. Serum levels of 25 (OH) D3, calcium, phosphorus, alkaline phosphatase and plasma level of parathormone were measured. Quantitative PCR for HCV was performed Bone density was determined by dual energy X-ray absorptiometry. All cases received conventional therapy, and only 33 patients received vitamin D supplementation.
RESULTS:
Children with HCV showed significantly increased levels of HCV RNA (P<0.001), parathormone (P<0.01) and decreased vitamin D levels (P<0.05) (33.3% deficient and 43.3% insufficient) compared with controls. Abnormal bone status (Z score -1.98±0.75) was found in ribs, L-spine, pelvis and total body. Cases treated with vitamin D showed significant higher early (P<0.04) and sustained (P<0.05) virological response. There was a high frequency of vitamin D deficiency among the Egyptian HCV children, with significant decrease in bone density. The vitamin D level should be assessed before the start of antiviral treatment with the correction of any detected deficiency.
CONCLUSION:
Adding vitamin D to conventional Peg/RBV therapy significantly improved the virological response and helped to prevent the risk of emerging bone fragility.

Reduced Hepatitis C response in those with higher levels of vitamin D - Aug 2014

Serum 25(OH)D3 levels affect treatment outcomes for telaprevir/peg-interferon/ribavirin combination therapy in genotype 1b chronic hepatitis C.
Dig Liver Dis. 2014 Aug;46(8):738-43. doi: 10.1016/j.dld.2014.05.004. Epub 2014 May 29.
Atsukawa M1, Tsubota A2, Shimada N3, Abe H4, Kondo C5, Itokawa N5, Nakagawa A5, Iwakiri K5, Kawamoto C6, Aizawa Y4, Sakamoto C6.

BACKGROUND:
Close relationships between chronic hepatitis C and vitamin D levels have been reported. For genotype 1b infection, the current standard of care is pegylated interferon/ribavirin therapy combined with a protease inhibitor. The present study analyzed the relationship between outcomes of triple therapy and serum 25(OH)D3 levels.
METHODS:
Factors contributing to sustained virological response were investigated in 177 patients with chronic hepatitis C who received telaprevir-based triple therapy in this prospective study.
RESULTS:
The sustained virological response rate was 86.9% in patients with 25(OH)D3 levels of >18 ng/ml; this was higher than the 66.7% in patients with 25(OH)D3 levels of ≤ 18 ng/ml (P=0.003). 25(OH)D3 levels and IL28B genotype were identified as significantly independent factors contributing to sustained virological response. The sustained virological response rate did not differ according to 25(OH)D3 levels in patients with the IL28B major genotype. The sustained virological response rate was 64.9% in patients with the IL28B minor genotype and 25(OH)D3 levels of >18 ng/ml, and was 38.5% in those with decreased 25(OH)D3 levels (P=0.045).
CONCLUSIONS:
In triple therapy, 25(OH)D3 levels were an independent factor contributing to sustained virological response. Of particular note, the sustained virological response rate was significantly lower in patients with the IL28B minor genotype.

Vitamin D reduced Hepatitis C in Hepatocellular Carcinoma Cell Line - May 2019

Previously, we have reported that the active vitamin D metabolite, calcitriol and vitamin D3 (cholecalciferol), both remarkably inhibit hepatitis C virus production. The mechanism by which vitamin D3 exerts its effect is puzzling due to the low levels of calcitriol produced in vitamin D3-treated Huh7.5 cells. In this study, we aimed to explore the mechanism of vitamin D3 anti-hepatitis C virus effect. We show that vitamin D3 activity is not mediated by its metabolic conversion to calcitriol, but may be due to its primary metabolic product 25(OH)D3. This is inferred from the findings that 25(OH)D3 could inhibit hepatitis C virus production in our system, and that adequate concentrations needed to exert this effect are produced in Huh7.5 cells treated with vitamin D3. Using the CRISPR-Cas9 editing technology to knockout the vitamin D receptor, we found that the antiviral activity of vitamin D3 and 25(OH)D3 was not impaired in the vitamin D receptor knockout cells. This result indicates that 25(OH)D3 anti-hepatitis C virus effect is exerted by a vitamin D receptor-independent mode of action. The possibility that vitamin D3 and 25(OH)D3, being 3β-hydroxysteroids, affect hepatitis C virus production by direct inhibition of the Hedgehog pathway in a vitamin D receptor-independent manner was ruled out. Taken together, this study proposes a novel mode of action for the anti-hepatitis C virus activity of vitamin D3 that is mediated by 25(OH)D3 in a vitamin D receptor-independent mechanism.
