Wilson's disease in association with anetoderma.

BACKGROUND: Wilson's disease is an autosomal recessive disorder of copper homeostasis with predominantly hepatic and neuropsychiatric involvement. Anetoderma is a rare benign condition with focal damage of dermal elastic tissue. Previous reports described this skin disorder in association with prolonged D-Penicillamine therapy. CASE PRESENTATION: A 26-year-old male was referred for evaluation of asymptomatic elevation of aminotransferase levels. Investigations showed negative markers for chronic viral and autoimmune hepatitis, low ceruloplasmin level, and increased copper urinary excretion. Liver biopsy revealed chronic hepatitis with moderate activity and severe bridging fibrosis. Mutation analysis found a compound heterozygote genotype and supported a diagnosis of Wilson's disease. At the time of the primary physical exam, skin lesions were also observed, consisting of numerous white to pale papules less than 7-8 mm in diameter with central protrusion located at the upper part of the body. Primary anetoderma was established based on presentation and skin biopsy findings. Therapy with D-Penicillamine at a daily dose of 1500 mg was started, and, during 12-month follow-up, aminotransferase decreased to normal and skin lesions remained unchanged. CONCLUSION: In our opinion the case is a first reported association between Wilson's disease and primary anetoderma. The possible mechanism behind this relationship is discussed.

Prevalence of vitamin D deficiency and insufficiency in Bulgarian patients with chronic hepatitis C viral infection.

AIMS: The present pilot study aimed to determine vitamin D status in Bulgarian patients with chronic HCV infection in respect to the severity of liver disease and response to interferon-ribavirin therapy. METHODS: The study encompassed 296 patients: 161 males (54.4%) aged 42.08 ± 14.87 years, 135 females (45.6%) aged 45.72 ± 14.34 years, 86.5% of them infected with HCV genotype 1. Total 25-hydroxyvitamin-D (25OHD) was determined by liquid chromatography/tandem-mass spectrometric detection. RESULTS: The median 25OHD level of the studied cohort was 50.40 nmol/L (range: 29.6-71.05). 25OHD deficient (< 25 nmol/L) were 16% of patients, 33% showed profound insufficiency (25-50 nmol/L), another 33% were in the range 50-80 nmol/L (mild insufficiency), the rest 18% were 25OHD sufficient. Significantly lower 25OHD levels were registered in cases with advanced fibrosis compared to those with mild or absent fibrosis (37.10 nmol/L vs. 53.00 nmol/L, respectively, p < 0.05). This association remained unchanged by seasonal variations in 25OHD levels. Inverse relationship was found between 25OHD and HCV-RNA (p < 0.01). Patients with sustained virological response to therapy had significantly higher 25OHD levels, compared to patients who failed to achieve viral eradication (56.90 nmol/L vs. 45.00 nmol/L, p = 0.012). CONCLUSION: More than 80% of HCV-infected patients were vitamin D-deficient and -insufficient. The inverse relationship between 25OHD levels and viral load, liver fibrosis and treatment outcomes supports the hypothesis that improvement of vitamin D status may have considerable potential to amend the host defense against HCV infection and response to therapy.

Randomized, double-blind study of emtricitabine (FTC) plus clevudine versus FTC alone in treatment of chronic hepatitis B.

Emtricitabine (FTC) is approved for the treatment of human immunodeficiency virus. FTC and clevudine (CLV) have activity against hepatitis B virus (HBV). This report summarizes the results of a double-blind, multicenter study of patients with chronic hepatitis B who had completed a phase 3 study of FTC and were randomized 1:1 to 200 mg FTC once daily (QD) plus 10 mg CLV QD or 200 mg FTC QD plus placebo for 24 weeks with 24 weeks of follow-up. One hundred sixty-three patients were treated (82 with FTC plus CLV [FTC+CLV] and 81 with FTC); 72% were men, 53% were Asian, 47% were Caucasian, and 52% were hepatitis B e antigen positive, and the median baseline HBV DNA level was 6 log(10) copies/ml. After 24 weeks of treatment, 74% (FTC+CLV) versus 65% (FTC alone) had serum HBV DNA levels of <4,700 copies/ml (P = 0.114) (Digene HBV Hybrid Capture II assay). Twenty-four weeks posttreatment, the mean change in serum HBV DNA levels from baseline was -1.25 log(10) copies/ml (FTC+CLV), 40% had undetectable viremia (versus 23% for FTC alone), and 63% had normal alanine aminotransferase levels (versus 42% for FTC alone) (P < or = 0.025 for all endpoints). The safety profile was similar between arms during treatment, with less posttreatment exacerbation of hepatitis B in the combination arm. In summary, after 24 weeks of treatment, no significant difference between arms was observed, but there was a significantly greater virologic and biochemical response 24 weeks posttreatment in the FTC+CLV arm.
