Factors influencing cytomegalovirus DNA load measurements in whole blood and plasma specimens from allogeneic hematopoietic stem cell transplant reci…

2019

We assessed the impact of several parameters, including the nature of the episode of Cytomegalovirus (CMV) DNAemia, the use of preemptive antiviral therapy, and the blood cell content in CMV DNA loads measured in whole blood (WB) and plasma (PL). CMV DNA load was quantified in 245 paired specimens collected within 43 postengraftment episodes of CMV DNAemia by using the CMV RealTime CMV PCR (Abbott Molecular). Concordant categorical results were obtained for 78.4% of paired specimens (Kappa index, 0.385; P = 0.001). Overall, CMV DNA loads in PL were higher than those in WB (mean bias, +0.115 log IU/mL) in both initial and recurrent episodes; this was so in post-antiviral treatment but not in…

Real life experiences in HCV management in 2018

2019

Introduction: Hepatitis C virus (HCV) infection is a major cause of chronic liver disease, with approximately 71 million chronically infected individuals worldwide. Treatment of chronic hepatitis C has considerably improved in the last few years thanks to the introduction of direct-acting antivirals able to achieve sustained virological response in more than 95% of patients. Successful anti-HCV treatment can halt liver disease progression and solve the HCV-related extra-hepatic manifestations, eventually reducing liver-related and overall mortality. Areas covered: With the aim to respond to unmet needs in patient’s identification, universal access to antiviral therapy and treatment optimiza…

Early experiences from one of the first treatment programs for chronic hepatitis B in sub-Saharan Africa

2017

Treatment for chronic hepatitis B (CHB) is virtually absent in sub-Saharan Africa. Here we present early experiences from a pilot program for treatment of CHB in Ethiopia. Adults (≥18 years) with CHB were included in a cohort study at St. Paul’s Hospital Millennium Medical College, Addis Ababa, from February 2015. The baseline assessment included liver function tests, viral markers and transient elastography (Fibroscan 402, Echosense, France). Logistic regression models were used to identify predictors of fibrosis. Tenofovir disoproxil fumarate (TDF) was initiated based on the European Association for the Study of the Liver (EASL) criteria, with some modifications. The initial 300 patients …

Treatment of chronic hepatitis B in sub-Saharan Africa: 1-year results of a pilot program in Ethiopia

2018

Background The World Health Organization has set an ambitious goal of eliminating viral hepatitis as a major public health threat by 2030. However, in sub-Saharan Africa, antiviral treatment of chronic hepatitis B (CHB) is virtually unavailable. Herein, we present the 1-year results of a pilot CHB treatment program in Ethiopia. Methods At a public hospital in Addis Ababa, CHB patients were treated with tenofovir disoproxil fumarate based on simplified eligibility criteria. Baseline assessment included liver function tests, viral markers, and transient elastography (Fibroscan). Changes in laboratory markers were analyzed using Wilcoxon signed-rank tests. Adherence to therapy was measured by …

Predictors of mortality in patients under treatment for chronic hepatitis B in Ethiopia: a prospective cohort study

2019

Abstract Background Antiviral treatment for chronic hepatitis B (CHB) is largely unavailable in sub-Saharan Africa; hence, little is known about the prognosis after initiating treatment in African CHB patients. In this study we aimed to assess predictors of mortality in one of the largest CHB cohorts in sub-Saharan Africa. Methods Two-hundred-and-seventy-six CHB patients who started treatment with tenofovir disoproxil fumarate at a public hospital in Ethiopia between March 18, 2015, and August 1, 2017, were included in this analysis. Patients were followed up until October 1, 2017, and deaths were ascertained through hospital records and telephone interview with relatives. Decompensated cir…

The WHO guidelines for chronic hepatitis B fail to detect half of the patients in need of treatment in Ethiopia

2019

Background & Aims In 2015, the World Health Organization (WHO) issued guidelines for the management of chronic hepatitis B (CHB) in low- and middle-income countries, but little is known about the applicability of the WHO treatment criteria in sub-Saharan Africa. The aim of this study was to evaluate the diagnostic performance of the WHO guidelines in a large CHB cohort in Ethiopia. Methods Treatment-naive adults who attended a public CHB clinic in Addis Ababa were included in this analysis. All patients underwent a standardized evaluation at recruitment, including blood tests and transient elastography (Fibroscan®). A Fibroscan result >7.9 kPa was used to define significant fibrosis and >9.…

Hepatitis C virus early kinetics and resistance-associated substitution dynamics during antiviral therapy with direct-acting antivirals

2018

The emergence of resistance-associated substitutions (RASs) can compromise the high efficacy of direct-acting antivirals (DAAs). Little is known about RASs selection at very early time points during DAA treatment. Therefore, we analyzed the potential emergence of RASs immediately after therapy initiation. Samples of 71 patients treated with different DAAs were collected at baseline, during therapy (hours 4 and 8; days 1-7; weeks 2-4) or until target not detected. HCV-RNA levels were determined by qPCR, and RASs were detected by deep sequencing. Sixty-three (89%) patients achieved a sustained virological response (SVR), 7 (10%) relapsed, and 1 (1%) experienced a breakthrough. Almost all non-…
