Economic Consequences of Anti-HCV Treatment of Patients Diagnosed Through Screening in Italy: A Prospective Modelling Analysis

Aim To evaluate the cost-consequences of the investment for anti-hepatitis C virus (HCV) treatment by the Italian National Health System (NHS) for patients who will be newly diagnosed through active HCV screening, implemented in Italy from 2020. Methods A previously published Markov model was used to estimate the disease complications avoided and the associated savings over 20 years to treat a standardised population of 10,000 HCV-infected patients diagnosed as a result of screening. Disease progression probabilities and fibrosis stage distribution were based on previously reported data in the literature. Real-life treatment effectiveness and medical expenses for disease management were estimated starting from a representative cohort of HCV-treated patients in Italy (Italian Platform for the Study of Viral Hepatitis Therapies). The breakeven point in time (BPT) was defined as the years required for the initial investment in treatment to be recovered in terms of cumulative costs saved. Results Over a 20-year time horizon, the treatment of 10,000 standardized patients diagnosed through active HCV screening results in 7769 avoided events of progression, which are associated with euro838.73 million net savings accrued by the Italian NHS. The initial investment in treatment is recouped in 4.3 years in the form of savings from disease complications avoided. Conclusion Investment in treatment of newly diagnosed patients will bring a significant reduction in disease complications, which is associated with great economic benefits. This type of action can reduce the infection rate as well as the clinical and economic disease burden of HCV in Italy

The impact of direct acting antivirals on hepatitis C virus disease burden and associated costs in four european countries

Background and Aims We assessed the clinical and economic impact of direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) in England, Italy, Romania and Spain.Methods An HCV progression Markov model was developed considering DAA eligibility and population data during the years 2015-2019. The period of time to recover the investment in DAAs was calculated as the cost saved by avoiding estimated clinical events for 1000 standardized treated patients. A delayed treatment scenario because of coronavirus disease (COVID-19) was also developed.Results The estimated number of avoided hepatocellular carcinoma, decompensated cirrhosis and liver transplantations over a 20-year time horizon was: 1,057 in England; 1,221 in Italy; 1,211 in Romania; and 1,103 in Spain for patients treated during 2015-2016 and 640 in England; 626 in Italy; 739 in Romania; and 643 in Spain for patients treated during 2017-2019. The cost-savings ranged from euro 45 to euro 275 million. The investment needed to expand access to DAAs in 2015-2019 is estimated to be recovered in 6.5 years in England; 5.4 years in Italy; 6.7 years in Romania; and 4.5 years in Spain. A delay in treatment because of COVID-19 will increase liver mortality in all countries.Conclusion Direct-acting antivirals have significant clinical benefits and can bring substantial cost-savings over the next 20 years, reaching a Break-even point in a short period of time. When pursuing an exit strategy from strict lockdown measures for COVID-19, providing DAAs should remain high on the list of priorities in order to maintain HCV elimination efforts

Hepatitis A, B and C viral co-infections among HIV-infected adults presenting for care and treatment at Muhimbili National Hospital in Dar es Salaam, Tanzania

<p>Abstract</p> <p>Background</p> <p>Tanzania is currently scaling-up access to anti-retro viral therapy (ART) to reach as many eligible persons as possible. Hepatitis viral co-infections are known to influence progression, management as well as outcome of HIV infection. However, information is scarce regarding the prevalence and predictors of viral hepatitis co-infection among HIV-infected individuals presenting at the HIV care and treatment clinics in the country.</p> <p>Methods</p> <p>A cross-sectional study conducted between April and September 2006 enrolled 260 HIV-1 infected, HAART naïve patients aged ≥18 years presenting at the HIV care and treatment clinic (CTC) of the Muhimbili National Hospital (MNH). The evaluation included clinical assessment and determination of CD4+ T-lymphocyte count, serum transaminases and serology for Hepatitis A, B and C markers by ELISA.</p> <p>Results</p> <p>The prevalence of anti HAV IgM, HBsAg, anti-HBc IgM and anti-HCV IgG antibodies were 3.1%, 17.3%, 2.3% and 18.1%, respectively. Dual co-infection with HBV and HCV occurred in 10 individuals (3.9%), while that of HAV and HBV was detected in two subjects (0.8%). None of the patients had all the three hepatitis viruses. Most patients (81.1%) with hepatitis co-infection neither had specific clinical features nor raised serum transaminases. History of blood transfusion and jaundice were independent predictors for HBsAg and anti-HBc IgM positivity, respectively.</p> <p>Conclusion</p> <p>There is high prevalence of markers for hepatitis B and C infections among HIV infected patients seeking care and treatment at MNH. Clinical features and a raise in serum alanine aminotransferase were of limited predictive values for the viral co-infections. Efforts to scale up HAART should also address co-infections with Hepatitis B and C viruses.</p

Sero-prevalence and risk factors for hepatitis B virus infection among health care workers in a tertiary hospital in Uganda

BACKGROUND: Hepatitis B virus (HBV) infection is a global public health challenge. Prevalence of current hepatitis B virus infection in the general population in Uganda is about 10%. Health care workers (HCW) have an extra risk of getting infected from their workplace and yet they are not routinely vaccinated against HBV infection. This study aimed at estimating prevalence of hepatitis B virus infection and associated risk factors among health care workers in a tertiary hospital in Uganda. METHODS: Data were obtained from a cross sectional survey conducted in Mulago, a national referral and teaching hospital in Uganda among health care workers in 2003. A proportionate to size random sample was drawn per health care worker category. A structured questionnaire was used to collect data on socio-demographic characteristics and risk factors. ELISA was used to test sera for HBsAg, anti-HBs and total anti-HBc. Descriptive and logistic regression models were used for analysis. RESULTS: Among the 370 participants, the sero-prevalence of current hepatitis B virus infection was 8.1%; while prevalence of life time exposure to hepatitis B virus infection was 48.1%. Prevalence of needle stick injuries and exposure to mucous membranes was 67.8% and 41.0% respectively. Cuts were also common with 31.7% of doctors reporting a cut in a period of one year preceding the survey. Consistent use of gloves was reported by 55.4% of respondents. The laboratory technicians (18.0% of respondents) were the least likely to consistently use gloves. Only 6.2% of respondents were vaccinated against hepatitis B virus infection and 48.9% were susceptible and could potentially be protected through vaccination. Longer duration in service was associated with a lower risk of current infection (OR = 0.13; p value = 0.048). Being a nursing assistant (OR = 17.78; p value = 0.007) or a laboratory technician (OR = 12.23; p value = 0.009) were associated with a higher risk of current hepatitis B virus infection. Laboratory technicians (OR = 3.99; p value = 0.023) and individuals with no training in infection prevention in last five years (OR = 1.85; p value = 0.015) were more likely to have been exposed to hepatitis B virus infection before. CONCLUSIONS: The prevalence of current and life time exposure to hepatitis B virus infection was high. Exposure to potentially infectious body fluids was high and yet only a small percentage of HCW were vaccinated. There is need to vaccinate all health care workers as a matter of policy and ensure a safer work environment

Non-travel related Hepatitis E virus genotype 3 infections in the Netherlands; A case series 2004 – 2006

<p>Abstract</p> <p>Background</p> <p>Human hepatitis E virus (HEV) infections are considered an emerging disease in industrialized countries. In the Netherlands, Hepatitis E virus (HEV) infections have been associated with travel to high-endemic countries. Non-travel related HEV of genotype 3 has been diagnosed occasionally since 2000. A high homology of HEV from humans and pigs suggests zoonotic transmission but direct molecular and epidemiological links have yet to be established. We conducted a descriptive case series to generate hypotheses about possible risk factors for non-travel related HEV infections and to map the genetic diversity of HEV.</p> <p>Methods</p> <p>A case was defined as a person with HEV infection laboratory confirmed (positive HEV RT-PCR and/or HEV IgM) after 1 January 2004, without travel to a high-endemic country three months prior to onset of illness. For virus identification 148 bp of ORF2 was sequenced and compared with HEV from humans and pigs. We interviewed cases face to face using a structured questionnaire and collected information on clinical and medical history, food preferences, animal and water contact.</p> <p>Results</p> <p>We interviewed 19 cases; 17 were male, median age 50 years (25–84 y), 12 lived in the North-East of the Netherlands and 11 had preexisting disease. Most common symptoms were dark urine (n = 16) and icterus (n = 15). Sixteen ate pork ≥ once/week and six owned dogs. Two cases had received blood transfusions in the incubation period. Seventeen cases were viremic (genotype 3 HEV), two had identical HEV sequences but no identified relation. For one case, HEV with identical sequence was identified from serum and surface water nearby his home.</p> <p>Conclusion</p> <p>The results show that the modes of transmission of genotype-3 HEV infections in the Netherlands remains to be resolved and that host susceptibility may play an important role in development of disease.</p
