“…Although no epidemiological reports have indicated that athletes who take part in contact sports have a significantly higher prevalence of HBV infection [ 3 , 4 ], 3 previous case reports have shown HBV outbreaks among athletes who engage in contact sports, such as sumo wrestling and American football [ 5 – 7 ]. In all studies, the infections were presumed to have been transmitted horizontally from an index case to contacts via skin abrasions.…”

“…The spread of hepatitis B vaccination has been slower in Japan than in other countries. Three cases of horizontal transmission of HBV in contact sports have been previously reported in Japan [ 5 – 7 ]. The American Medical Society for Sports Medicine (AMSSM) has issued an advisory to alert clinicians regarding the risk of transmission of blood-borne pathogens such as HBV by contact sports [ 8 ].…”

“…Although post-transplant HBV vaccination is an alternative that may provide a chance to discontinue prophylaxis by producing anti-HBs, close monitoring of serum HBV markers is needed. Furthermore, based on the fact that Japanese adults are not obligated to undergo HBV vaccination (22), pre-transplant HBV vaccination is crucial for potential recipients of LT in Japan (19).…”

The use of hepatitis B core antibody (anti-HBc)-positive grafts is one strategy for expanding the donor pool for liver transplantation (LT). The aim of this study was to determine the risk factors associated with hepatitis B virus (HBV) recurrence after living donor LT (LDLT) of anti-HBc-positive grafts. From January 1996 to December 2018, a total of 609 LDLT procedures were performed at our center. A retrospective review was performed for 31 patients (23 males and 8 females; median age = 47 years) who underwent LDLT for HBVunrelated liver disease from anti-HBc-positive donors. The factors associated with HBV recurrence were evaluated and compared between the HBV recurrence and non-recurrence groups. The median follow-up period after LT was 135 months (range, 6-273 months). Four of 31 patients (12.9%) developed post-LT HBV recurrence. All four cases were HBV-naïve patients (anti-HBc-negative and Hepatitis B surface antibody-negative). The median interval between LDLT and HBV recurrence was 42 months (range, 20-51). The overall actuarial rates of HBV recurrence at 1, 3, 5, 10, and 20 years were 0%, 7.2%, 15.7%, 15.7%, and 15.7%, respectively. Although there were no significant differences between the HBV recurrence and non-recurrence groups, HBV recurrence tended to occur in HBV-naïve recipients (P = 0.093). HBV-naïve status may contribute to HBV recurrence after LDLT for HBV-unrelated liver disease from anti-HBc-positive donors. Careful monitoring for serological HBV markers is needed, particularly in this group.

“…A total of 1.34 million people died from viral hepatitisrelated chronic liver disease or hepatocellular carcinoma (HCC) in 2015, which was comparable to deaths caused by tuberculosis and higher than those caused by human immunodeficiency virus (HIV) [2]. Transmission of hepatitis viruses, such as HBV, has been documented by non-conventional routes among athletes participating in contact sports like wrestling [3][4][5] and football [6] due to close contact of the subjects and bleeding from combat activities and collisions occurring in any contact sport [7,8]. The risks of transmission of hepatitis viruses among elite athletes are hard to quantify owing to the scarcity of data in the literature.…”

Chronic Viral Hepatitis in Elite Athletes: Approaches to Risk Assessment, Prevention and Management

2022

Elite athletes who participate in contact sports are at risk of bleeding injuries, leading to transmission of blood-borne viruses including hepatitis type B, C and D (HBV, HCV and HDV) capable of causing chronic liver disease, liver failure and liver cancer. In view of the significant advances in the viral hepatitis field over the past decade, more structured approaches should be in place to screen for and manage viral hepatitis in elite athletes. HBV status should be assessed in all elite athletes, and those infected should receive nucleos(t)ide analogues for viral suppression, while uninfected individuals should receive HBV vaccination. The all-oral direct acting antivirals for HCV are highly effective and safe, thus the remaining challenge with hepatitis C is case identification and linkage to care. HDV is only found in HBV-infected individuals, which is characterized by rapid disease progression and higher rates of cirrhosis and liver cancer in infected subjects. Pegylated interferon was the mainstay of treatment for HDV infection until bulevirtide, a viral entry inhibitor, was recently approved by the European Union (EMA) and FDA in America, while multiple novel therapies are already in clinical trials as part of the HBV cure program. Overall, awareness of chronic viral hepatitis in athletes should be improved. Prevention remains the cornerstone of the management of viral hepatitis in sport coupled with rigorous disease assessment in infected individuals, and antiviral therapy where indicated.
