With the advent and subsequent success of antiretroviral therapy, human immunodeficiency virus (HIV) infection has largely become a chronic condition and is increasingly seen alongside metabolic disorders such as dyslipidaemia and insulin resistance. Furthermore, the administration of antiretroviral therapy (ART) itself is associated with an increase in the incidence of metabolic risk factors (namely insulin resistance, lipoatrophy, dyslipidaemia, and abnormalities of fat distribution in HIV patients). Thus, further challenges in the management of HIV patients include the management of diabetes and the metabolic syndrome, non-alcoholic fatty liver disease (NAFLD)...

Primary HIV drug resistant mutations are mutations that occur in an HIV-infected individual prior to the initiation of antiretroviral therapy (ART). These mutations may arise by de novo mutagenesis or result from transmission. Drug resistant mutations (DRMs) may reduce the effectiveness of ART leading to inadequate virological outcomes. Currently, Sanger sequencing is the standard method for detection of DRMs to inform treatment decisions, but does not detect minor variant mutations. Drug resistant minority variants (DRMVs) can be detected by next generation sequencing (NGS)...

The effectiveness of modern antiretroviral therapies (ART) transformed HIV infection into a chronic disease characterized by a persistent condition of inflammation and immune activation. For this reason, even thought AIDS-related mortality has been reduced with an increased life expectancy, patients living with HIV infection are more likely to develop non-AIDS events despite the achievement of a complete suppression of HIV replication. Hence, the scientific community feels the need to find new biomarkers which would be suitable in clinical practice for identifying patients who require a close monitoring because of an increased risk of developing comorbidities...

HIV-positive individuals are at increased risk for cardiovascular disease due to complex interactions between the increased incidence of traditional cardiovascular risk factors and HIV and antiretroviral-associated inflammation and dyslipidemia. Increasing evidence suggests that a number of important co-pathogens, including cytomegalovirus, hepatitis C virus, and periodontal disease, are likely to also be contributing. Mechanisms such as molecular mimicry and modification of lipids play a role; however, induction of systemic inflammation is the likely key pathogenic link by which this occurs...

Global scale-up of antiretroviral treatment (ART) has dramatically changed the prospects of HIV/AIDS disease rendering life-long chronic care and treatment a reality for millions of HIV-infected patients. Affordable technologies to monitor ART are needed to ensure long-term durability of limited available drug regimens. HIV drug resistance tests can complement existing strategies in optimizing clinical decision-making for patients with treatment failure, in addition to facilitating population-based surveillance of HIV drug resistance...

Patients living with HIV have an increased risk of cardiovascular disease that is considered to be the result of an interaction between traditional cardiovascular risk factors, particularly smoking and dyslipidemia, and persistent chronic inflammation and immune activation associated with HIV infection, along with side effects of antiretroviral therapy. In the general population, the administration of statins has been associated with a reduction in cardiovascular disease-associated mortality, and these drugs are among the most common class of medication prescribed in high-income countries...

In Brazil, a nurse recently became infected with HIV-1 despite beginning antiretroviral therapy within one hour following accidental needle stick injury while puncturing the forearm of an HIV-infected patient with detectable plasma viremia. Thereafter, the patient's virus was found to harbor multiple drug resistance mutations.

In the era of efficacious and well-tolerated treatment for chronic hepatitis C virus (HCV) infection, there is an expanding population of individuals who achieve viral eradication. This in turn has generated a need to determine the impact of liver-related morbidity and mortality, particularly liver decompensation and hepatocellular carcinoma, in populations achieving sustained viral response (SVR), and how they correlate with that of the general population.

In the absence of antirretroviral therapy (ART), HIV infection leads to progression to AIDS in most infected individuals. However, there is a small group of HIV-infected patients capable of spontaneously controlling HIV infection, known as the elite controllers (less than 1% of total infected population). These patients maintain undetectable levels of HIV replication, in part, due to a continuously effective HIV specific T cell response. Moreover, in HIV-infected patients with suppressed viremia under ART, a chronic activation of the immune system persist, which can be related to a poor clinical outcome including death, development of co-morbidities, AIDS and non-AIDS defining events...

The II Conference of the Group for the Study of Viral Hepatitis (GEHEP) (29 September-1 October, Spain) updated epidemiological, diagnostic and treatment aspects on viral hepatitis. The conference was mostly focused on the latest news related to HCV infection, including the successes achieved since the implementation of direct-acting antiviral agents for HCV therapy, but also in the new, future challenges for a real HCV eradication. The scenario for chronic HCV infection has dramatically changed in the last two years and most patients have been cured after 12 weeks of therapy with minimal side effects...

Non-alcoholic fatty liver disease is one of the most frequent chronic hepatic conditions worldwide. The spectrum of non-alcoholic fatty liver disease goes from hepatic steatosis to steatohepatitis, cirrhosis, and hepatocellular carcinoma. Risk factors for non-alcoholic fatty liver disease are metabolic, mainly obesity and the accompanying consequences. Treatment and prevention of non-alcoholic fatty liver disease should target those metabolic abnormalities. The frequency of and the factors associated with hepatic steatosis in HIV infection seem to be similar to those reported in the general population, though direct comparisons are lacking...

Stefano Bonora, Massimo Puoti
The burden of HIV and HCV coinfection is estimated to affect 5-7 million people worldwide, with approximately 15-30% of people with HIV coinfected with HCV. The first oral direct-acting antivirals have shown to improve the response in patients with HIV/HCV coinfection, and more recently, other direct-acting antivirals that target various stages of the HCV life cycle have been developed, among them daclatasvir. The objective of this article is to examine recent clinical studies investigating the efficacy and safety of daclatasvir in comparison with other antiretroviral drugs, focusing on its efficacy in the coinfected HIV patient and real-life data...

The dosage of darunavir/ritonavir is 800/100 mg once daily for treatment-naive patients or treatment-experienced patients with no prior darunavir resistance associated mutations, and 600/100 mg twice daily for treatment-experienced patients with one or more darunavir resistance associated mutations. Results from the five available pharmacokinetic studies show reductions in total darunavir plasma concentrations of between 20-50% during the third trimester of pregnancy. The unbound darunavir concentrations have been measured only in subsets of patients in two of the five pharmacokinetic studies...

The pathogenic mechanisms of the accelerated progression of liver injury in HIV/HCV coinfection are incompletely understood. The progression of liver disease is variable between individuals having similar risk factors, suggesting that genetic background is an important contributor. The aim of this review is to give a summary of all single nucleotide polymorphisms associated with the severity of liver disease in patients coinfected with HIV and HCV reported in the literature. Therefore, a systematic search for articles published was made, 17 of which were selected for this review...

REVIEW
Carmen de Mendoza
Budget constrictions have pushed some researchers to explore whether antiretroviral therapy with one or two drugs instead of the well-established triple-drug regimens may be able to maintain undetectable viremia in HIV-infected individuals, at least used as simplification in patients already with viral suppression under standard triple therapy. With the advent of co-formulations and the improved safety of the newest antiretroviral agents, there is no other reason than cost to justify moving from triple to dual or monotherapy...

Two billion people have been exposed to HBV and exhibit serological markers of past infection such as anti-HBc and/or anti-HBs. However, around 240 million suffer from chronic hepatitis B, as defined by the presence of serum HBsAg for longer than six months. In addition, a small proportion of patients exposed to HBV may harbor detectable viremia (serum HBV DNA) in the absence of HBsAg, which is named "occult hepatitis B".

The increasing use of antiretrovirals for averting HIV infection before potential exposure is under debate. Whereas there is no doubt about the benefit of using Truvada® (tenofovir plus emtricitabine) to reduce HIV acquisition in uninfected persons who have sex with HIV-infected stable partners, concerns are rising about the increasing rate of sexually transmitted infections in subjects engaged in sex with multiple partners, due to misinterpreted self-security.

Approximately 30% of HIV individuals are coinfected with HCV. It is known that HIV accelerates liver fibrosis progression, even with the use of combination antiretroviral therapy, and HCV is now a leading cause of morbidity and mortality in this patient population. Past HCV therapy with pegylated interferon and ribavirin in this setting has demonstrated poor outcomes, which were inferior to those seen in HCV-monoinfected populations, especially in patients with genotype 1 infections. This and the high rate of adverse events with these agents resulted in very limited uptake of these treatment options...

Although more than one in two HIV-infected persons may develop central fat accumulation soon after commencing antiretroviral therapy, the association between antiretroviral therapy and body fat changes has not been consistent across primary epidemiological studies. We conducted a systematic review with meta-analyses to estimate the pooled effects of antiretroviral therapy on different measures of body fat, and to examine factors that potentially modify these effects. We searched for studies that compared body mass index, waist circumference, combined overweight/obesity, and central obesity between HIV-infected adults naive and exposed to antiretroviral therapy...

Both human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infection are important global public health problems with shared transmission routes. Although HIV/HCV coinfection is not uncommon, the prevalence rates vary significantly across different studies and regions. In Taiwan, injection drug users have become the major contributors to the HIV/AIDS epidemic since 2005. Because the prevalence of HCV infection is high in injection drug users, this HIV epidemic is also associated with a significant increase of HIV/HCV coinfection in Taiwan...
