DAA Treatment Failure in a HIV/HBV/HCV Co-Infected Patient Carrying a Chimeric HCV Genotype 4/1b
No full textApproved direct antiviral agent (DAA) combinations are associated with high rates of sustained virological response (SVR) and the absence of a detectable hepatitis C viral load 12–24 weeks after treatment discontinuation. However, a low percentage of individuals fail DAA therapy. Here, we report the case of a HIV/HBV/HCV co-infected patient who failed to respond to DAA pangenotypic combination therapy. The sequencing of NS5a, NS5b, NS3 and core regions evidenced a recombinant intergenotypic strain 4/1b with a recombination crossover point located inside the NS3 region. The identification of this natural recombinant virus underlines the concept that HCV recombination, even if it occurs rarely, may play a key role in the virus fitness and evolution
Hepatitis a outbreak in men who have sex with men (MSM) in Brescia (Northern Italy), July 2016-July 2017
No full textSince June 2016, an outbreak of hepatitis A has been reported in Europe. Here we report the HAV outbreak in Brescia (Northern Italy) from July 2016 to July 2017. We actively recorded all HAV cases defined by detection of HAV IgM antibodies in serum. Data on sexual behaviour, travel attitudes, concomitant sexually transmitted diseases (STDs), clinical presentation and laboratory results were collected. Forty-two confirmed cases were recorded: 25 (60%) were MSM and reported sexual contact at risk of STDs. Compared to 2015 and the first half of 2016, when only three hepatitis A cases were recorded, in the 12 months in question the number of cases rose 14-fold. Among 25 MSM, 14 were HIV-infected. Hepatitis A is usually a self-limiting disease, but it could be more serious in the case of HIV co-infection, immunosuppression and chronic hepatitis. HAV infection has a high outbreak potential in MSM because of more common oro-anal practices compared to HS, a high interconnectedness global network, chemsex practices and a new tendency to travel abroad to attend group sex events. In our experience, most cases occurred in MSM and 56% of them were HIV-infected, suggesting the need to promote active screening, immunization and education in this population
Tenofovir-induced Fanconi syndrome in chronic hepatitis B monoinfected patients that reverted after tenofovir withdrawal
No full textTenofovir disoproxil fumarate (TDF) is a nucleotide reverse transcriptase inhibitor widely used to treat patients with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infection. Despite the excellent safety records of this regimen, a few cases of acute renal failure and Fanconi syndrome have been reported among HIV patients exposed to TDF. In the HBV monoinfection scenario, only two cases of TDF-associated Fanconi syndrome have been reported thus far. Here, we describe two additional patients with chronic hepatitis B (CHB) who developed a TDF-induced Fanconi syndrome that reverted after TDF withdrawal and had viral replication fully suppressed upon switching to entecavir (ETV). Though the overall risk of TDF associated severe renal toxicity in HBV patients appears to be negligible, both glomerular and tubular function should be monitored in patients exposed to TDF, especially when other renal risk factors or a history of previous exposure to adefovir dipivoxil (ADV) are present
Hepatitis B virus reactivation after effective sofosbuvir and ribavirin treatment in a patient with occult hepatitis B virus infection
No full textReactivation of the hepatitis B virus (HBV) has been reported in patients with occult infection (OBI), i.e. HBV surface antigen (HBsAg) negative, HBV core antibody (anti-HBc) positive ± antibodies against HBsAg (anti-HBs) and detectable HBV DNA in serum or liver, receiving immunosuppressive or cytotoxic therapies. Recently, concerns have been raised regarding the risk of HBV reactivation in OBI patients treated with direct acting antiviral agents (DAAs) for chronic hepatitis C (CHC). Here we describe a case of HBV reactivation in a 72-year-old woman with OBI as a possible consequence of effective treatment with sofosbuvir (SOF) and ribavirin (Rbv) for genotype 2a/2c CHC
Lymphoproliferative disease with mixed cryoglobulinemia and hyperviscosity syndrome in an HIV-infected patient: HCV is the only culprit
No full textThe availability of direct antiviral agents (DAAs) offers the possibility to treat HCV-infected patients with a high rate of efficacy and a good safety profile. Little is known about the benefit of DAAs on HCV-related hematological diseases and their complications. We describe the case of an HIV/HCV-infected patient with HCV-related chronic lymphoproliferative disease, mixed cryoglobulinemia and hyperviscosity syndrome. Treatment with direct antiviral agents (DAAs) cured HCV infection and its complications, while HCV re-infection caused recrudescence of the associated diseases
Hepatitis B virus co-infection in human immunodeficiency virus-infected subjects
No full textShared epidemiological risks have resulted in HIV-infected populations having a high prevalence of hepatitis B virus (HBV) co-infection. Several prospective studies have investigated the impact of HBV co-infection on HIV disease progression; most of them were negative. On the contrary, there is evidence that HIV may modify the natural history of HBV infection. HIV positive subjects have higher rates of HBV chronification, higher HBV replication, lower ALT levels and lower rates of seroconversion to anti-HBe and anti-HBs. The impact of HIV co-infection on the outcome of HBV infection is still controversial, even if some studies have shown an accelerated progression towards decompensated cirrhosis in HIV co-infected subjects. HBV co-infection is a risk factor for severe hepatotoxicity during HAART. Vaccination for HBV is mandatory in nonimmune HIV subjects, however its efficacy in immunosuppressed patients is still controversial. HIV co-infection decreases the effectiveness of Interferon in the treatment of HBV infection. Because of its activity against both HBV and HIV, lamivudine is used in HIV-HBV co-infected patients at doses of 300 mg/daily and as part of an antiretroviral regimen, but the rate of sustained response is poor and HBV strains with mutations associated with lamivudine resistance occur at a rate of 20% per year. Trials of new drugs with activity against HBV, some of them with activity also against HIV, and some of them without cross-resistance with lamivudine, are now underway. Highly Active Anti-Hepatitis B Therapy will probably soon come of age
The Semantics of the Gaze: Fazio’s Mistress in Fazio Degli Uberti’s and Dante Gabriel Rossetti’s Representations
No full textThe intention of this paper is to discuss the act of (not) looking with respect to the fourteenth-century Italian poem His Portrait of His Lady, Angiola of Verona written by Fazio Degli Uberti, and Dante Gabriel Rossetti’s painting Fazio’s Mistress (Aurelia). The works chosen for this analysis seem to represent social conventions and expectations related to gender and sexuality. Both in the case of the painting and the poem, the gaze is a medium
of becoming a “surveyor” and “surveyed”, a means of typecasting, but also a reservoir of changing meanings. In the following discussion, the author approaches Uberti’s and Rossetti’s works in attempt to see how (and if) they renounce traditional views on domination and submission
High rates of 30-day mortality in patients with cirrhosis and COVID-19
No full textBackground & Aims: Coronavirus disease 2019 (COVID-19) poses a major health threat to healthy individuals and those with comorbidities, but its impact on patients with cirrhosis is currently unknown. Herein, we aimed to evaluate the impact of COVID-19 on the clinical outcome of patients with cirrhosis. Methods: In this multicentre retrospective study, patients with cirrhosis and a confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection were enrolled between 1st and 31th March 2020. Clinical and biochemical data at diagnosis of COVID-19 and at the last outpatient visit were obtained through review of medical records. Results: Fifty patients with cirrhosis and confirmed SARS-CoV-2 infection were enrolled (age 67 years, 70% men, 38% virus-related, 52% previously compensated cirrhosis). At diagnosis, 64% of patients presented fever, 42% shortness of breath/polypnea, 22% encephalopathy, 96% needed hospitalization or a prolonged stay if already in hospital. Respiratory support was necessary in 71%, 52% received antivirals, 80% heparin. Serum albumin significantly decreased, while bilirubin, creatinine and prothrombin time significantly increased at COVID-19 diagnosis compared to last available data. The proportion of patients with a model for end-stage liver disease (MELD) score ≥15 increased from 13% to 26% (p = 0.037), acute-on-chronic liver failure and de novo acute liver injury occurred in 14 (28%) and 10 patients, respectively. Seventeen patients died after a median of 10 (4–13) days from COVID-19 diagnosis, with a 30-day-mortality rate of 34%. The severity of lung and liver (according to CLIF-C, CLIF-OF and MELD scores) diseases independently predicted mortality. In patients with cirrhosis, mortality was significantly higher in those with COVID-19 than in those hospitalized for bacterial infections. Conclusion: COVID-19 is associated with liver function deterioration and elevated mortality in patients with cirrhosis. Lay summary: Coronavirus disease 2019 (COVID-19) poses a major health threat to healthy individuals and those with comorbidities. Herein, we assessed its impact on patients with cirrhosis. Infection with COVID-19 was associated with liver function deterioration and elevated mortality in patients with cirrhosis
A territory‐wide opportunistic, hospital‐based HCV screening in the general population from northern Italy: The 1969–1989 birth‐cohort
No full textBackground and Aim: The World Health Organization (WHO) goal of Hepatitis C Virus (HCV) elimination by 2030 rose awareness about the need of screening plans, worldwide. In Italy, graduated screening starting from people born in 1969–1989 might be the most-effective strategy. We performed an opportunistic HCV screening study in the general population attending health facilities in Lombardy region, Northern Italy. Methods: This is a prospective, multicenter, territory-wide, opportunistic study supported by the Regional Government of Lombardy, Italy. Between June 2022 and December 2022, all subjects born in 1969–1989, hospitalized or accessing blood collection centres were offered anti-HCV and HCV–RNA tests. Patients with known anti-HCV positivity and/or previous anti-HCV treatment were excluded. Demographic features were uploaded into a regional web-based platform. Results: In total, 120 193 individuals were screened in 75 centres. Mean age was 44 (±6) years, 65.2% were females, 83.7% were tested at blood collection centres. Anti-HCV tested positive in 604 (0.50%) subjects: mean age 47 (±5), 51.1% females. HCV seroprevalence was higher in males (p < 0.00001), elderly (p < 0.00001) and in- vs. outpatients (p = 0.0009). HCV–RNA was detectable in 125 out of 441 (28.3%) anti-HCV positive subjects. Actively infected patients were 46 (±6) years old, mainly males (56.8%). The overall prevalence of active HCV infection was 0.10%, higher in elderly (p = 0.0003) and in in-patients (p = 0.0007). Among 93 HCV–RNA positive patients, the median age was 48 years, 58% males, 62% Italian born, median HCV–RNA levels were 6,1 log IU/mL, liver stiffness measurement (LSM) values 5.5 (3.1–29.9) kPa and ALT levels 48 U/L. Conclusions: The prevalence of active HCV infection in the 1969–1989 population attending health facilities in Lombardy was low. Most viremic patients were Italian-born, with mild liver disease but high-HCV–RNA levels. Due to the higher prevalence in the elderly, the extension of such opportunistic screening programs to lower birth cohorts would be warranted
