Insights
Vitamin D deficiency is common in children with hepatitis C virus (HCV) infection and is linked to poor bone health. Supplementation improved antiviral treatment outcomes.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Endocrinology
Background:
- Hepatitis C virus (HCV) infection is prevalent in children.
- Vitamin D deficiency is a potential comorbidity in HCV patients.
- Bone health may be compromised in children with HCV.
Purpose of the Study:
- To determine the prevalence of vitamin D deficiency in pediatric HCV patients.
- To assess the impact of vitamin D supplementation on antiviral therapy efficacy.
- To evaluate bone mineral density in children with HCV.
Main Methods:
- A case-control study involving 66 children with HCV and 28 healthy controls (aged 7-14 years).
- Measurement of serum 25(OH)D3, calcium, phosphorus, alkaline phosphatase, parathormone, and HCV RNA.
- Bone density assessment using dual-energy X-ray absorptiometry; 33 HCV patients received vitamin D supplementation alongside conventional therapy.
Main Results:
- Children with HCV exhibited higher HCV RNA and parathormone levels, and lower vitamin D levels (33.3% deficient, 43.3% insufficient) compared to controls.
- Abnormal bone density was observed in HCV patients.
- Vitamin D supplementation led to significantly improved early and sustained virological response.
Conclusions:
- Vitamin D deficiency is frequent in Egyptian children with HCV, associated with reduced bone density.
- Assessing and correcting vitamin D levels before antiviral treatment is recommended.
- Vitamin D supplementation enhances virological response and mitigates bone fragility risk in HCV treatment.
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.
