Long term changes in thrombocytopenia and leucopenia after HCV eradication with direct-acting antivirals.

BACKGROUND: Thrombocytopenia due to hypersplenism is a major complication of hepatitis C virus (HCV)-associated cirrhosis. HCV eradication improves these complications in some patients, but the long-term effects of HCV eradication on these complications remain unclear, especially in patients treated with direct acting antivirals (DAAs). The aim was to evaluate long term changes in thrombocytopenia and leucopenia after HCV eradication with DAAs. METHODS: The present multicenter study retrospectively evaluated changes over 5 years in thrombocytopenia and leukocytopenia, as well as changes in liver fibrosis markers and spleen size, in 115 patients with HCV-cirrhosis treated with DAAs. RESULTS: Thrombocytopenia and leukocytopenia were improved 4 weeks after DAA administration, with thrombocytopenia show further gradual improvement over the next year. Fib-4 index was markedly reduced 1 year after DAA, followed by subsequent gradual reduction over the next 4 years. Spleen size showed gradual annual reductions, with patients experiencing spleen size reduction characterized at baseline by bilirubinemia. CONCLUSIONS: Rapid DAA-associated HCV eradication might lead to rapid disappearance of liver inflammation and bone marrow suppression due to HCV infection. HCV eradication may gradually improve portal hypertension, reducing spleen size.

[Rhabdomyolysis associated with long-term treatment of esomeprazole].

Proton pump inhibitors (PPIs) have been widely used in the treatment of gastroesophageal reflux disease and peptic ulcer disease. Although they have a potent acid suppressive effect and excellent efficacy in acid-related diseases, PPI-induced rhabdomyolysis has been reported. Here, we report the case of a patient with reflux esophagitis who developed rhabdomyolysis after esomeprazole treatment. A 67-year-old man with reflux esophagitis who had started esomeprazole treatment for the preceding 10 months complained of back and limb fatigue and myalgia. His serum creatinine kinase (CK) level was markedly elevated, and CK isozyme exhibited an MM pattern. He was diagnosed with rhabdomyolysis induced by esomeprazole. The cessation of esomeprazole rapidly improved his symptoms, and the serum CK level was normalized within 16 days. PPI-induced rhabdomyolysis is a rare complication. In most cases, PPI-induced rhabdomyolysis occurs within 3 months after starting PPIs. However, rhabdomyolysis occurred at 10 months after starting esomeprazole treatment in our patient. Early diagnosis of PPI-induced rhabdomyolysis is required even in long-term PPI users.

Direct-acting antivirals for hepatitis C virus-infected patients with hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-infected patients has a high risk of recurrence. Although eradication of HCV is expected to reduce this risk, the risk in patients with a history of HCC may be high after treatment with direct-acting antivirals (DAAs). AIM: To determine the risk factors for HCC recurrence in patients with HCV and a history of HCC. METHODS: The risk of HCC recurrence in patients with a history of HCC and/or of HCC occurrence in patients without a history of HCC after DAA therapy was retrospectively analyzed in 311 HCV patients treated at our institution and several neighboring hospitals. The frequency and predictors of HCC recurrence/ occurrence after DAA treatment were included in these analyses. The clinical course of HCC before and after DAA treatment was also evaluated. RESULTS: HCV patients with a history of HCC were older and had greater progression of liver fibrosis and diabetes than patients without a history of HCC. Median recurrence-free survival (RFS) was 1092 d in patients with a history of HCC, and post-DAA HCC recurrence/occurrence was observed in 29 patients (53.7%) with and 5 (1.9%) without a history of HCC over 6 years (P < 0.001). RFS in patients with a history of HCC did not differ significantly before and after DAA treatment. The frequency of HCC recurrence/occurrence in patients with a history of HCC was lower after than before DAA treatment. Multivariate analysis showed that the incidence rate of HCC recurrence/occurrence before DAA treatment was the only independent predictor of HCC recurrence/occurrence after DAA treatment. Liver function was well preserved and clinical course was good in patients with HCC recurrence/occurrence after DAA therapy. CONCLUSION: DAA therapy in patients infected with HCV is also effective in patients with a history of HCC. Curative treatment for HCC is desirable before DAA therapy. The frequency of HCC recurrence/occurrence before DAA therapy was associated with a significantly increased risk of HCC recurrence after DAA therapy. Careful observation after DAA therapy is required in patients with a history of HCC.

Impact of Post-progression Survival on Outcomes of Lenvatinib Treatment for Unresectable Hepatocellular Carcinoma: A Systematic Review and Retrospective Cohort Study.

BACKGROUND/AIM: Lenvatinib is a tyrosine kinase inhibitor (TKI) more effective against hepatocellular carcinoma (HCC) than sorafenib, making lenvatinib a first-line treatment option for patients with unresectable HCC. In patients treated with sorafenib, post-progression survival (PPS) rather than progression-free survival (PFS) is essential for overall survival (OS). However, the importance of PPS for OS in patients treated with lenvatinib is uncertain, and optimal treatment after lenvatinib failure has not yet been established. PATIENTS AND METHODS: The present study investigated the correlations of PFS and PPS with OS in studies of HCC patients treated with lenvatinib by weighted linear regression analysis. Furthermore, the contribution of treatment regimens after lenvatinib failure to OS were evaluated in daily clinical practice. RESULTS: An analysis of 20 studies with 4,054 patients found that PPS had a stronger correlation with OS (r=0.869, p<0.001) than did PFS (r=0.505, p=0.007). Analysis of 79 patients with unresectable HCC treated with first-line lenvatinib showed that subsequent treatment was the most significant contributor to OS. Second-line sorafenib was administered to 25 patients, with late transition to third-line treatment being highest among patients who received second-line treatment. CONCLUSION: PPS contributes significantly to OS in HCC treatment with TKIs, with multi-sequential treatment being a key determinant of longer OS.
