Human immunodeficiency virus (HIV)-1 and hepatitis C virus (HCV) are major contributors to the global disease burden with many experts recognizing the requirement of an effective vaccine to bring a durable end to these viral epidemics. The most promising vaccine candidates that have advanced into pre-clinical models and the clinic to eliminate or provide protection against these chronic viruses are viral vectors [e.g., recombinant cytomegalovirus, Adenovirus, and modified vaccinia Ankara (MVA)]. This raises the question, is there a need to develop DNA vaccines against HIV-1 and HCV? Since the initial study from Wolff and colleagues which showed that DNA represents a vector that can be used to express transgenes durably in vivo , DNA has been regularly evaluated as a vaccine vector albeit with limited success in large animal models and humans...

Raltegravir (RAL) is an HIV-1 integrase strand transfer inhibitor that is well established as a component of highly active antiretroviral therapy regimens for the treatment of adults living with human immunodeficiency virus (HIV), due to its high virological efficacy and good tolerability profile. To date, limited data are available on the use of RAL with abacavir/lamivudine (ABC/3TC). We investigated retrospectively 62 HIV-1 infected patients managed by three Italian Infectious Diseases Outpatient Departments, including 57 treatment-experienced patients and 5 treatment-naïve patients, treated with ABC/3TC plus RAL...

BACKGROUND: Hepatic steatosis is prevalent in Western countries, but few studies have evaluated whether the frequency and severity of steatosis are greater in the setting of HIV infection. We compared the prevalence and severity of hepatic steatosis between HIV-infected (HIV+) and uninfected persons and identified factors associated with greater steatosis severity within both groups. METHODS: We performed a cross-sectional study among participants without cardiovascular disease who participated in a substudy of the Veterans Aging Cohort Study...

Background: As antiretroviral therapy has become more effective, persons with HIV live longer and develop conditions that are characteristic of older populations. Understanding changes in comorbid conditions has important implications for the complexity and cost of care, particularly for Medicaid programs and their enrollees, which comprise about 40% of all persons with HIV. Thus, our objective was to examine trends in comorbid conditions for Medicaid enrollees with HIV. Methods: Using 2001-2012 administrative claims data from the 14 states (NY, CA, FL, TX, MD, NJ, PA, IL, GA, NC, VA, LA, OH, MA) with the highest HIV prevalence, we identified 494 322 unique Medicaid enrollees with HIV, representing 5...

Chronic benign CD8+ proliferation is a rare syndrome that can take the form of a variety of other diseases. Peripheral adenopathy, cytopenia, and infiltration of the liver, kidneys, bowels, or other organs are the most common clinical presentations of the syndrome. CD8+ expansion can be clonal and nonclonal. It generally occurs in patients with innate or acquired immunodeficiency (HIV+) or in patients receiving immunosuppressive therapy. It has been found repeatedly in patients who developed severe hypogammaglobulinemia after treatment with rituximab...

Liver disease in human immunodeficiency virus (HIV) remains a main cause of morbidity and mortality. Liver-related morbidity and mortality can be caused by multiple etiologic factors, including opportunistic infections, direct and indirect effects of antiretrovirals, direct and indirect effects of HIV, and viral hepatitides. These factors present with varied liver pathophysiologic mechanisms that lead to abnormalities in liver enzymes and synthetic function test, followed by distinct clinical presentations...

BACKGROUND: Increased Risk Donors (IRDs) are a significant proportion of the deceased organ donor pool but may be declined by patients on the liver transplant waiting list due to various factors. We conducted a survey of patients with end-stage liver disease awaiting a liver transplant in order to determine the factors leading to the acceptance of an IRD organ, and what strategies we could use to better inform and increase this rate of acceptance. METHODS: Adult liver transplant candidates who were outpatients completed a survey consisting of 51 questions on a 5-point Likert scale, with categories related to demographics, knowledge of IRDs, and likelihood of acceptance...

OBJECTIVE: Hepatitis C virus (HCV) treatment may reduce liver-related mortality but with competing risks, other causes of mortality may undermine benefits. We examined changes in cause-specific mortality among HIV-HCV coinfected patients before and after scale-up of HCV treatment. DESIGN: Prospective multicentre HIV-HCV cohort study in Canada. METHODS: Cause-specific deaths, classified using a modified 'Coding of Cause of Death in HIV' protocol, were determined for two time periods, 2003-2012 and 2013-2017, stratified by age (20-49; 50-80 years)...

Allogeneic hematopoietic cell transplantation (allo-HCT) is a potentially curative therapy for hematologic malignancies in persons living with HIV (PLHIV), however, uncertainties exist in many domains related to their care, including optimal donor selection, conditioning regimen, immunosuppression for graft-versus-host disease (GVHD), and long-term outcomes. We undertook a comprehensive systematic review from multiple databases to evaluate the foregoing uncertainties. The final sample comprised 49 patients (median age at HCT, 34 years; 46 males [93...

EXECUTIVE SUMMARY: The risk of cervical cancer (CC) among women immunosuppressed for a variety of reasons is well documented in the literature. Although there is improved organ function, quality of life and life expectancy gained through use of immunosuppressant therapy, there may be increased long-term risk of cervical neoplasia and cancer and the need for more intense screening, surveillance, and management. Although guidance for CC screening among HIV-infected women (see Table 1) has been supported by evidence from retrospective and prospective studies, recommendations for CC screening among non-HIV immunosuppressed women remains limited because quality evidence is lacking...

With the successes of antiretroviral therapy, patients infected with human immunodeficiency virus (HIV) living longer. Regarding this, the common diseases of HIV population (i.e., opportunistic infections) are now losing ground in front of metabolic alterations. This phenomenon is related to the delay in progression to acquired immune deficiency syndrome (AIDS), making it so that patients live in a chronic inflammatory state which, combined with other mechanisms such infectious ones, cause metabolic diseases...

Through record linkage we describe causes of death among persons with diagnosis of HCV in England. Persons ≥1yrs with anti-HCV/HCV-PCR tests reported to PHE sentinel surveillance during 2002-2016 were linked to death registrations from the Office for National Statistics during 2008-2016. We fouind that 8.6% of the 204,265 with evidence of HCV during the study period died. Among them, external causes (accidental poisoning from drugs) and liver disease (end stage liver disease, liver cancer, hepatitis, alcohol and non-alcohol related) were the leading underlying causes of death (18% and 34...

People with haemophilia represent a population with a high prevalence of HCV infection due to the use of blood components and plasma-derived clotting factor concentrates before the introduction of viral-inactivating procedures (in the 1980s) and screening for HCV (in the 1990s). About 80% of HCV-infected patients have chronic HCV infection, and at least 20% develop end-stage liver disease. The aim of the study was to assess current anti-HCV positivity in a large cohort of Brazilian haemophilia patients and to determine associated factors with HCV exposure...
