Spontaneous clearance of serum HCV-RNA after splenectomy in a patient with HCV-related liver cirrhosis and portal hypertension: a case report. Surg Case Rep 2024; 10:94. [PMID: 38647617 PMCID: PMC11035502 DOI: 10.1186/s40792-024-01899-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Accepted: 04/13/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND Spontaneous clearance of chronic hepatitis C virus (HCV) is rare in adults. A T-lymphocyte response is thought to be involved in HCV-RNA clearance. Splenectomy reportedly has a beneficial effect on T cell immune function in patients with cirrhosis. To the best of our knowledge, the present report is the first to describe spontaneous clearance of serum HCV-RNA within 1 year after splenectomy in a patient with cirrhosis. CASE PRESENTATION A 55-year-old man with HCV cirrhosis was transferred to our institution with advanced pancytopenia, splenomegaly, and gastric varices. He had a 1-year history of ascites, edema, and general fatigue. The patient had a Child-Pugh score of 8 and serological type 1 HCV; the HCV-RNA level was 4.7 log IU/mL. Contrast-enhanced computed tomography showed gastric varices and marked splenomegaly (estimated spleen volume of 2175 mL). Esophagogastroduodenoscopy revealed enlarged gastric varices with no red color sign, and the varices were larger than those 1 year prior. He was diagnosed with decompensated HCV-related liver cirrhosis and portal hypertension. We considered direct-acting antiviral (DAA) therapy; however, DAA therapy was not approved in Japan for patients with decompensated cirrhosis at that time. Hand-assisted laparoscopic splenectomy was performed to improve the worsening portal hypertension. Further, we planned the initiation of DAA therapy after surgery, when such therapy would become available. DAA therapy was approved 1 year after splenectomy. At that time, we measured the HCV-RNA level before the initiation of DAA therapy; unexpectedly, however, serum HCV-RNA was not detectable, and the virus continued to disappear during the following 4 years. His liver function (total bilirubin, albumin, and prothrombin time) and pancytopenia improved during the 5 years postoperatively. The serum aspartate and alanine aminotransferase levels normalized between 1 and 5 years postoperatively. Esophagogastroduodenoscopy showed no change in the gastric varices during the 5 years after surgery. The patient remained asymptomatic and continued to do well. CONCLUSIONS We have presented a case of spontaneous clearance of HCV-RNA after splenectomy in a patient with cirrhosis and portal hypertension. Splenectomy may be associated with disappearance of HCV-RNA based on previous reports. More cases should be accumulated and evaluated.

Abstract
BACKGROUND AND AIM Liver function can be improved in patients with chronic hepatitis C virus (HCV) infection who achieved sustained virologic response (SVR) with direct-acting antiviral (DAA) treatment. However, to our knowledge, the impact of liver function improvement after SVR on prognosis has not been investigated. METHODS A total of 716 patients with chronic HCV infection and compensated advanced liver fibrosis who began receiving DAA treatment between September 2014 and August 2018 in 25 Japanese hospitals and achieved SVR were enrolled. RESULTS The median age was 73 years, and 336 (47%) and 380 (53%) patients had albumin-bilirubin (ALBI) grade 1 and grade 2, respectively. Improvement to ALBI grade 1 at 1 year after the end of treatment (EOT) was observed in 76% of the patients with baseline ALBI grade 2. Among 380 patients with baseline ALBI grade 2, alanine aminotransferase (ALT) levels ≥ 40 U/L (p < 0.001) and modified ALBI (mALBI) grade 2a (p < 0.001) were significantly associated with improvement to ALBI grade 1 at 1 year after EOT in multivariate analysis. During the median observation period of 51.8 months, 4 and 10 patients with baseline ALBI grade 1 and 2, respectively, died. In patients with baseline ALBI grade 2, only the absence of improvement to ALBI grade 1 at 1 year after EOT was significantly associated with all-cause mortality in univariate analysis. CONCLUSIONS Baseline ALT levels and mALBI grade were significantly associated with improvement in liver function after SVR. Patients whose liver function improved after SVR could have better prognosis.

Response to antiviral therapy for chronic hepatitis C and risk of hepatocellular carcinoma occurrence in Japan: a systematic review and meta-analysis of observational studies. Sci Rep 2023; 13:3445. [PMID: 36859564 PMCID: PMC9977913 DOI: 10.1038/s41598-023-30467-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 02/23/2023] [Indexed: 03/03/2023] Open
Abstract
In Japan, hepatocellular carcinoma (HCC) is a leading cause of cancer mortality and hepatitis C virus infection is a major cause of HCC. We conducted a systematic review and meta-analysis of published studies evaluating patient response to antiviral therapy for chronic hepatitis C on the risk of HCC occurrence in Japan. Articles were searched using terms determined a priori through PubMed, screened by title and abstract, and selected by full-text assessment according to criteria determined a priori, including HCC occurrence in response to interferon (IFN)-based or IFN-free therapy, Japanese study, and 2 or more years of follow-up. We excluded studies on HCC recurrence. We calculated the pooled estimate of the crude incidence rate ratio with data from the selected studies using the person-years method with Poisson regression model and pooled estimate of the hazard ratio adjusted for potential confounders reported by the studies using a random effects model. A total of 26 studies were identified, all of which examined only IFN-based therapy as a result of the selection process. The pooled estimate (95% confidence interval [CI]) of 25 studies was 0.37 (0.33-0.43) for sustained virologic response (SVR) and 1.70 (1.61-1.80) for non-SVR for the HCC incidence rate per 100 person-years, and 0.22 (0.19-0.26) for the incidence rate ratio (SVR vs. non-SVR). The pooled estimate of the hazard ratio (95% CI) of HCC incidence adjusted for potential confounders of 8 studies was 0.25 (0.19-0.34). SVR to interferon therapy for chronic hepatitis C reduces the risk of HCC occurrence.

Abstract
AIM To determine the impact of direct-acting antiviral therapy on the long-term prognosis of decompensated cirrhotic patients. METHODS A total of 37 patients with hepatitis C virus-induced decompensated cirrhosis treated with sofosbuvir and velpatasvir (SOF/VEL group) were prospectively enrolled. For historical control, 65 hepatitis C virus-positive decompensated cirrhotic patients who did not receive direct-acting antiviral therapy were included (control group). The incidence rates of hepatocellular carcinoma (HCC), decompensated events with hospitalization, and overall survival were compared between both groups. RESULTS A total of 41 patients experienced decompensated events during 15.0 months in the control group, and six patients during 21.6 months in the SOF/VEL group. The cumulative incidence rates of decompensated events after 2 years were significantly higher in the control group (53.1%) than in the SOF/VEL group (14.5%; p < 0.001). A total of 27 patients died within 22.0 months in the control group, and three patients died within 25.6 months in the SOF/VEL group. The overall survival rates after 2 years were significantly lower in the control group (67.6%) than in the SOF/VEL group (91.3%; p = 0.010). A total of 13 patients in the control group developed HCC during 15.8 months, and 10 patients during 17.3 months in the SOF/VEL group. The HCC incidence rates after 2 years were 20.3% and 29.6% in the control and SOF/VEL groups, respectively, with no significant difference (p = 0.327). CONCLUSIONS SOF/VEL therapy may suppress the development of decompensated events and improve the prognosis in decompensated cirrhotic patients; however, the incidence of HCC remains prevalent in these patients irrespective of SOF/VEL therapy.

Abstract
Zinc is an essential trace element for the maintenance of life because it acts as a center of activity or cofactor for hundreds of enzymes. Zinc deficiency causes a variety of symptoms, including anemia, dermatitis, stomatitis, alopecia, bedsores, decreased appetite, impaired growth, gonadal dysfunction, susceptibility to infection, and taste disorders, etc. In March 2017, zinc acetate hydrate, which had been approved for Wilson disease in Japan, received an additional indication for hypozincemia. Hypozincemia is frequently observed in patients with chronic liver disease (CLD), especially cirrhosis, and it has recently been shown that hypozincemia is closely related to the development of liver fibrosis and increased risk of liver carcinogenesis, in addition to the appearance of various subjective symptoms. Moreover, hypozincemia in CLD may be associated with sarcopenia (i.e., decrease in muscle strength and muscle mass) and frailty (i.e., vulnerability), which receive much attention these days. It is assumed that treatment with zinc acetate hydrate will become widespread in patients with CLD. Zinc acetate hydrate may also have potential for improving sarcopenia in patients with CLD. This review primarily outlines the significance of zinc in patients with CLD.

Abstract
Objective This retrospective, single-center study assessed the effects of interferon (IFN)-free treatment of hepatitis C virus (HCV) infection, which has been approved for seven years; calculated the incidence of hepatocellular carcinoma (HCC) after achieving a sustained virologic response (SVR); and elucidated problems with follow-up for surveillance of post-SVR HCC, particularly the impact of the coronavirus disease 2019 (COVID-19) pandemic. Methods We summarized the SVR achievement rate of 286 HCV-infected patients who received 301 IFN-free treatments and analyzed the cumulative incidence of initial HCC and the cumulative continuation rate of follow-up after SVR in the 253 patients who achieved SVR and did not have a history of HCC. Results Among 286 patients who received IFN-free treatments, 14 dropped out, and the 272 remaining patients achieved an SVR after receiving up to third-line treatment. Post-SVR HCC occurred in 18 (7.1%) of the 253 patients without a history of HCC, with a cumulative incidence at 3 and 5 years after SVR of 6.6% and 10.0%, respectively; the incidence of cirrhosis at those time points was 18.2% and 24.6%, respectively.Of the 253 patients analyzed, 58 (22.9%) discontinued follow-up after SVR. Patients who had no experience with IFN-based therapy tended to drop out after SVR. Notably, the number of dropouts per month has increased since the start of the pandemic. Conclusion Currently, IFN-free treatment is showing great efficacy. However, the incidence of HCC after SVR should continue to be monitored. In this study, the COVID-19 pandemic did not affect treatment outcomes, but it may affect surveillance for post-SVR HCC.

Abstract
AIM Hepatocellular carcinoma (HCC) after sustained virologic response (SVR) has been observed even in hepatitis C virus (HCV) patients without advanced liver fibrosis. Identifying predictors for HCC incidence in patients without advanced liver fibrosis will enable efficient post-SVR HCC surveillance. This study aimed to develop a scoring system to predict the incidence of HCC after SVR in HCV patients without advanced liver fibrosis. METHODS A total of 1682 HCV patients without advanced liver fibrosis (defined as Fibrosis-4 index <3.25) with no history of HCC who initiated direct-acting antiviral treatment between September 2014 and October 2020 at 26 institutions, and achieved SVR24, were included. We divided 1682 patients into training (1122) and validation (560) cohorts. RESULTS In the multivariate analysis, baseline age ≥ 65 years (p = 0.030), alanine aminotransferase (ALT) levels at SVR24 ≥ 30 U/l (p = 0.001), and α-fetoprotein (AFP) levels at SVR24 ≥ 5.0 ng/ml (p = 0.001) were independent predictors for HCC incidence in the training cohort. We developed a scoring system to predict HCC incidence after SVR24 using these three factors (1 point was added for each factor). The cumulative HCC incidence rates at 5 years were 7.1% in patients who scored 2 or 3, and no patients developed HCC in those who scored 0 in the validation cohort. CONCLUSIONS Our scoring system using the three factors of baseline age, ALT levels at SVR, and AFP levels at SVR is useful for post-SVR HCC surveillance of patients without advanced liver fibrosis.

Abstract
Background and Aim The development of hepatocarcinogenesis after a sustained virological response (SVR) remains an important issue affecting the balance between treatment and occupational life of workers with chronic hepatitis C virus (HCV) infection in Japan. Here, we aimed to evaluate the hepatocellular carcinoma (HCC) reducing effect and risk factors for developing HCC after SVR in patients treated with direct‐acting antiviral agents (DAAs) among the working population. Methods We studied 2579 working patients with chronic HCV infection who achieved SVR after antiviral treatment. We compared the difference in the cumulative incidence of post‐SVR HCC between the interferon (IFN)‐based n = 1615 and DAA (n = 964) groups. The risk factors for post‐SVR HCC development were determined in the DAA group. Results After propensity score matching (n = 644 in each group), the HCC development rates were not significantly different between the groups (P = 0.186). Multivariate Cox regression and the cutoff values determined by the receiver operating characteristic curve analyses revealed that age ≥61 years, diabetes, lower serum albumin levels <4.0 g/dL at 24 weeks after the end of treatment (EOT), and higher serum α‐fetoprotein levels ≥4.1 ng/mL at 24 weeks after the EOT were associated with the development of HCC. Conclusion The HCC suppressing effect after SVR through DAA treatment is equivalent to that of IFN treatment in patients in the working population. Intensive follow‐up is required after SVR with DAA treatment in Japanese workers with these risk factors to ensure the promotion of health and employment support.

Abstract
In Japan, the estimated number of chronic HBV infections was 1.1-1.2 million and that of chronic HCV was 0.9-1.3 million in 2015. The mortality of hepatocellular carcinoma (HCC) had been increasing and hit a peak at around 2002, which subsequently started to decrease. Japan has a national action plan for addressing viral hepatitis called, "Basic Act on Hepatitis Measures", established in 2009. "Basic Guidelines for Promotion of Control Measures for Hepatitis" was issued in 2011 and was updated in 2016, comprising 9 principles in order to promote measures to prevent hepatitis B and C. According to these guidelines, national and local government share screening costs for testing HBV and HCV for those residents who are over 40 years old. Thus, out-of-pocket expenses from examinees are free of charge or reduced to a minimum. In addition, for patients with chronic hepatitis B or C being treated: drug prices of nucleotide analogues, interferon treatment or direct antiviral agents, and examination expenses should be covered by a special program for viral hepatitis. From December 2018, the special coverage program of medical expenses, shared by central and local government, has started for patients with HBV- or HCV-induced liver cancer and decompensated cirrhosis. However, in the cascade-of-care of viral hepatitis in Japan, significant gaps still remain in the diagnosis, treatment and transition to patients in need. Several advantages have prevailed in Japanese health care systems for patients with viral liver disease compared to those in other countries in the Western Pacific Region. Therefore, Japan should take a lead in helping the implementation of a practical hepatitis action plan for each country in need.
