RESUMO

BACKGROUND: The conventional antiviral treatment of chronic hepatitis related to hepatitis C virus (HCV) often leads to anemia. In this case, it is necessary to reduce ribavirin dose or stop treatment, thus reducing the rate of sustained virological response. AIM: We investigated whether epoetin alpha administration improves treatment adherence and leads to higher percentage of response at the end of therapy and sustained virological response. METHODS: Two hundred and fourteen individuals with genotype 1b HCV-related chronic hepatitis underwent treatment with pegylated (peg)-interferon alpha-2A 180 µg once weekly and ribavirin 1,000-1,200 mg/day; 174 were responders. Forty individuals completed treatment with no hemoglobin reduction; 134 developed anemia during therapy. Anemic responders were distributed randomly into two groups: group 1 continued therapy with epoetin alpha addiction; group 2 continued antiviral therapy with ribavirin reduction only. RESULTS: Patients in group 1 achieved better control of hemoglobin levels (13.8 ± 1.2 g/dl at the end of therapy) than those in group 2 (11.5 ± 0.8 g/dl). Sustained virological response was 59.7% in group 1 compared with 34.4% in group 2 (p<0.01). CONCLUSIONS: In patients with 1b HCV-related chronic hepatitis who develop anemia during antiviral treatment, administration of epoetin alpha increases hemoglobin levels and the end-of-treatment rate and sustains virological response by improving treatment adherence.

RESUMO

PURPOSE: Only early detection of non-symptomatic patients is able to arrest the diffusion of the non-symptomatic HCV infection and lead to prompt treatment. Our aim was to attempt to correlate the presence of perihepatic lymph nodes and hepatitis C infection and to assess whether ultrasonography can have a role to promote specific investigations for pre-clinical diagnosis of virus C infection. METHOD: We performed a controlled study on a cohort of 7974 subjects from a town of 27000 inhabitants on the eastern coast of Sicily. Serologic hepatitis A, B and C markers, alanine aminotransferase levels and abdominal ultrasound examination according to size and number of peri-hepatic lymph nodes were performed on blind basis. RESULTS: One or more pathological lymph nodes were present in 684/7974 subjects. Haematochemical tests revealed the presence of anti-HCV positivity in 528/684 subjects with pathological lymph nodes and in 8/7290 subjects without pathological lymph nodes, there being a significant difference (P<0.0001) between the two groups. CONCLUSION: Our results confirm the association between perihepatic lymph nodes and virus C infection. Correct diagnostic assessment of this datum could lead not only to early diagnosis by specific blood test for HCV and consequent prompt aimed treatment, but could pave the way for efficacious territorial prevention and detection of an elevated percentage of likely non-symptomatic carriers.

RESUMO

BACKGROUND: Chronic infection with hepatitis C virus (HCV) is the most common infectious disease among heroin abusers, but it is recommended that specific treatment with interferon be delayed until at least 6 to 12 months after the end of drug addiction. OBJECTIVE: We investigated the response of heroin abusers to interferon treatment shortly after the end of detoxification treatment with methadone. METHODS: We studied 2 homogeneous groups of white Italian patients with chronic HCV infection: former male heroin abusers and males without a history of drug addiction. Tumor necrosis factor, interleukin-1beta, interleukin-2, activated monocytes, anti-HCV antibodies, HCV RNA, and alanine aminotransferase levels were assessed. Standard treatment was initiated with 5 MU interferon alpha-n2b administered subcutaneously once daily for 8 weeks. Patients with negative HCV-RNA findings at the end of 8 weeks received further treatment with 5 MU TIW subcutaneously for an additional 48 weeks. RESULTS: Thirty of 47 patients in group A (former heroin abusers) and 30 of 30 patients in group B (controls) completed the study. Heroin abusers presented a significantly enhanced response to treatment compared with the controls. After 8 weeks, HCV-RNA test results were negative in 27 of 30 patients in group A (90.0%) and in 25 of 30 in group B (83.3%) (P = NS). Onset of relapse occurred significantly later in heroin abusers (mean [SD], 53 [3] weeks) than in controls (26 [2] weeks) (P < 0.05). Cytokine levels and activated CD11 antigen-expressing monocytes were significantly (P < 0.001) higher in heroin abusers than controls. CONCLUSION: Heroin abusers with chronic HCV infection were successfully treated with interferon alpha-n2b soon after the end of detoxification treatment.

RESUMO

Laser therapy has gained wide acceptance and application in many medical disciplines. Side effects of laser therapy are rare and the most frequent mainly involve the skin. We describe a patient affected by familial adenomatous polyposis that had been repeatedly controlled and treated endoscopically using an Nd:Yag laser. He presented with a progressive hyperdynamic portal syndrome with ascites caused by some arterovenous fistulas. We hypothesize that a rare side effect of the laser treatment may have caused ischemic and coagulative tissue inflammation that triggered off the pathological communications between the arterial and portal circulation.
