Human Immunodeficiency Virus Pre-Exposure Prophylaxis: Is it the Answer?

With the development of effective therapies against human immunodeficiency virus (HIV), hepatitis C virus (HCV) infection has become a major cause of morbidity and mortality among patients with both infections (coinfection). In addition to the high prevalence of chronic HCV, particularly among HIV-infected injection drug users, the rate of incident HIV infections is increasing among HIV-infected men who have sex with men, leading to recommendations for education and screening for HCV in this population. Liver disease is the second leading and, in some cases, a preventable cause of death among coinfected patients. Those at risk for liver disease progression are usually treated with a combination of interferon (IFN) and ribavirin (RBV), which is not highly effective; it has low rates of sustained virologic response (SVR), especially for coinfected patients with HCV genotype 1 and those of African descent. Direct-acting antivirals might overcome factors such as immunodeficiency that can reduce the efficacy of IFN. However, for now it remains challenging to treat coinfected patients due to interactions among drugs, additive drug toxicities, and the continued need for combination therapies that include pegylated IFN. Recently developed HCV protease inhibitors such as telaprevir and boceprevir, given in combination with pegylated IFN and RBV, could increase the rate of SVR with manageable toxicity and drug interactions. We review the latest developments and obstacles to treating coinfected patients.

Patients with human immunodeficiency virus (HIV) infection have sustained alterations in metabolism (lipids and insulin/glucose homeostasis) and body composition (fat distribution) that are proatherogenic (the Figure). HIV infection itself and/or its therapies may contribute to these alterations (the Table); although most effects are reversible, there are some possibly irreversible consequences of treatment. With the relative restoration to health seen in the era of highly active antiretroviral therapy (HAART), many traditional risk factors and promoters of dyslipidemia and diabetes also are present; they interact with HIV-specific inducers to worsen dyslipidemia and to increase the prevalence of insulin resistance and diabetes. Figure. Overview of the effects of HIV and its therapies on CVD risk. The contribution of traditional risk factors must be kept in mind, and they may occur with increased prevalence in people with HIV infection (eg, smoking). HIV, likely through the inflammatory response, and antiretroviral therapies independently affect many of the mediators of CVD risk. The effects on lipids are a prominent but complex example; HIV infection lowers LDL levels, but antiretroviral therapy raises LDL back up to normal levels. The bidirectional arrows indicate associations, but there is not yet adequate proof of causality. The dotted arrow between body composition and CVD indicates that body fat is known to affect the mediators such as dyslipidemia and insulin resistance but may also have a direct effect. FFA indicates free fatty acids; ARV, antiretroviral. View this table: Table. Effects of HIV Treatment These disturbances in lipid and glucose metabolism and renal disease may contribute, at least in part, to the excess cardiovascular disease (CVD) morbidity and mortality observed in HIV-infected individuals (the Figure). However, the relative contribution to excess CVD risk of traditional CVD risk factors, especially smoking, compared with these infection- and treatment-specific complications requires clarification. More prospective data with multivariable modeling are needed. …

With successful antiretroviral therapy, patients infected with the human immunodeficiency virus (HIV) are living longer; however, recent reports suggest increased rates of coronary heart disease (CHD) among HIV-infected patients,1 and cardiovascular disease has become an important cause of morbidity and mortality in this population.2 Increased CHD rates in the HIV population may relate to traditional risk factors, including advancing age, higher smoking rates, dyslipidemia, insulin resistance, and impaired glucose tolerance. Cardiovascular disease may also be due to nontraditional factors, including changes in body composition with loss of subcutaneous fat and/or accumulation of visceral fat in some patients, inflammation, and direct effects of the virus on the vasculature, as well as to direct effects of specific antiretroviral drugs. Important questions remain as to the pathogenesis, detection, and treatment of cardiovascular disease and related risk factors in HIV-infected patients. These questions concern, among other things, the design of adequate trials to determine CHD incidence and the utility of existing CHD guidelines for screening, prevention, treatment, and risk stratification. To ascertain the state of the science with respect to these and related questions, a multidisciplinary conference with interested HIV specialists, cardiologists, endocrinologists, primary care physicians, National Institutes of Health representatives, and patient advocates was convened June 28–30, 2007, in Chicago, Ill, and chaired by Drs Steven Grinspoon and Robert Eckel. The discussions focused on 6 areas of interest, each with its own working group, including the following: (1) the contribution of metabolic and anthropometric abnormalities to cardiovascular disease risk factors (chaired by Drs Carl Grunfeld and Donald Kotler); (2) the epidemiological evidence for cardiovascular disease and its relationship to highly active antiretroviral therapy (HAART; chaired by Drs Judy Currier and Jens Lundgren); (3) the effects of HIV infection and antiretroviral therapy on the heart and vasculature (chaired by Drs Michael Dube …

The Uncertain Significance of Anti–Glomerular Basement Membrane Antibody Among HIV-Infected Persons With Kidney Disease

S tudies published over the past 3 years have tracked the incidence and course of human immunodeficiency virus (HIV) infection in relation to cardiac illness in both children and adults. 1 These studies show that subclinical echocardiographic abnormalities independently predict adverse outcomes and identify high-risk groups to target for early intervention and therapy.The Joint United Nations Program on HIV/AIDS estimates that 36.1 million people were living with HIV infection at the end of the year 2000. 2 If 8% to 10% of patients develop symptomatic heart failure over a 2-to 5-year period, 3 then 3 million cases of HIV-related heart failure will present during that period. 1 Cardiovascular manifestations of HIV have been altered by the introduction of highly active antiretroviral therapy (HAART) regimens.On one hand, HAART has significantly modified the course of HIV disease, lengthened survival, and improved the quality of life of HIV-infected patients.On the other hand, the early data have raised concerns that HAART is associated with an increase in both peripheral and coronary arterial diseases. 1The HAART-associated changes are relevant only to the minority of HIV-infected individuals worldwide who have access to HAART.Thus, studies conducted before HAART became available remain globally applicable.In this review article, the principal HIV-associated cardiovascular manifestations will be discussed, with an emphasis on new knowledge about prevalence, pathogenesis, and treatment.

Mississippi has the 10th highest rate of new human immunodeficiency virus (HIV) infections in the United States. The Mississippi State Department of Health (MSDH) integrated partner HIV testing into syphilis partner services (PS) in 2014, but the effectiveness of this as an HIV case finding strategy has not been evaluated. We identified all early syphilis (primary, secondary, and early latent) case records reported from July 1, 2014, to December 31, 2016, excluding case records for people concurrently newly diagnosed with HIV. Among sex partners of these people, we identified new diagnoses of early syphilis and HIV. We calculated the number needed to interview as the number of syphilis index case patients interviewed divided by the number of partners newly diagnosed with early syphilis or HIV. A total of 1535 (95%) of the 1619 early syphilis index case patients were interviewed for PS. These case patients named 2267 partners, of whom 1868 (82%) were contacted by MSDH. Among partners, 1508 (81%) tested for syphilis and 745 (56%) of 1321 partners not previously diagnosed with HIV were tested for HIV. Partner services identified 696 new early syphilis case patients (46%) and 24 (3.2%) new HIV case patients among partners. Sixty-four index case patient interviews were needed to identify 1 new case of HIV, and 2 interviews were needed to identify 1 new case of syphilis among partners. Syphilis PS allowed MSDH to interact with 1592 men who have sex with men over a 30-month period and was effective for identifying people newly infected with early syphilis and HIV. Increasing HIV testing among partners of syphilis case patients could increase HIV case finding in Mississippi.

Repeated exposure to HIV does not necessarily result in infection and HIV infection does not inevitably lead to the development of the AIDS. Multiple immunological and genetic features can confer resistance to HIV acquisition and progression at different steps in viral infection; a full understanding of these mechanisms could result in the development of novel therapeutic and vaccine approaches for HIV infection. In this review, we focus on the genetic mechanisms associated with resistance to HIV infection and to the progression to AIDS.

HAART and the HCV-infected liver: friend or foe?

Approximately 30 years ago, in June 1981, it was reported from theCenter forDiseaseControl andPrevention (CDC) that five, otherwise healthy, homosexual men in California had presented with pneumonia caused by Pneumocystis jiroveci pneumonia, a rare disease seen exclusively in individualswith a severely suppressed immune system. Several reports confirmed the initial observation and lent support to the possibility that a new sexually transmitted, infectious agent was circulating within the gay community in the United States. The clinical condition was named acquired immunodeficiency syndrome (AIDS). Two years later, a research team at the Institut Pasteur under the guidance of Francoise Barre-Sinoussi and Luc Montagnier isolated human immunodeficiency virus (HIV), the causative agent of AIDS, from a lymph node biopsy of a French patient. The isolation and characterization of HIV paved the way for the design of diagnosticmethods to identify the virus in blood andbloodproducts and towards the development of novel antiretroviral treatment (ART) to control HIV replication in infected patients. For their discoveries, Barre-Sinoussi and Montagnier were awarded the Nobel Prize in Physiology and Medicine in 2008.
