AbstractEpidemiological studies have shown that infection with the human immunodeficiency virus (HIV) is an influential risk factor for infection withMycobacterium tuberculosis(MTb), the rapid progression of the initial infection to active tuberculosis (TB), and the reactivation of latent TB infection. MTb infection is also one of the most common opportunistic infections in people with HIV, including AIDS patients receiving anti-retroviral therapy. Given the prevalence of HIV infection, the incidence of TB infection, which had begun to decline, is facing a severe situation. HIV associated with TB exerts an immense burden on the public health-care system, especially in countries with high incidences of HIV infection. Therefore, the global policies for the prevention and control of TB should be revised. Moreover, an increased investment in TB control has to be guaranteed. The purpose of this review is to summarize the recent progress in the prevention, treatment, and control of HIV and TB co-infection.

ABSTRACTWe describe three recent patients in whom evaluation of subacute, progressive encephalopathy led to the initial diagnosis of human immunodeficiency virus infection. The clinical neurological picture of a predominance of abnormalities of mental function with few elementary neurological deficits, in conjunction with a paucity of systemic symptoms and lack of evidence for prior opportunistic infections preceding the encephalopathy are notable. The cognitive, behavioral, and neuropsychiatric disturbances are described in detail to illustrate the range of manifestations of disordered mental states associated with encephalopathy in individuals with HIV infection. The importance of a comprehensive and broad-minded work-up by brain magnetic resonance imaging, cerebrospinal fluid examination, and specific microbiological tests in delineating the potential multifactorial pathogenesis of the cerebral syndromes in relation to the HIV infection is emphasized. The gratifying long-term clinical improvements in parallel with resolution of neuroimaging and other laboratory abnormalities in response, to antiretroviral drug treatment are reported.

Human immunodeficiency virus (HIV) causes breakdown of the immune system and predisposes patients to various opportunistic infections and neoplasms. However, many patients may not be aware of the HIV infection before the development of their first HIV related complications. We reported four unrecognised HIV patients presenting to our accident and emergency department with common complications of HIV infection and the acquired immunodeficiency syndrome (AIDS). Although not as common as in America, emergency physicians in Hong Kong still have to take care of patients with unknown HIV status. The common presentations of HIV patients will be discussed. A high index of suspicion and knowledge of common HIV/AIDS complications are required for managing these patients.

Latent Tb Infection

Tuberculosis (TB) is a major global public health problem and is the leading cause of death linked to a single pathogen, ranking above human immunodeficiency virus (HIV).1 Clinically, TB has been categorised as active disease (patients who are generally symptomatic and may be infectious if pulmonary involvement is present) and latent infection (asymptomatic and not infectious, but at variable risk for progression to active TB disease). It is increasingly being recognised that latent TB infection (LTBI) reflects diverse responses to infection with Mycobacterium tuberculosis and may lead to heterogeneous clinical outcomes. In an expert interview, Jean-Pierre Zellweger discusses the latest World Health Organisation (WHO) guidelines on the management of LTBI.

While there is no cure, antiretroviral therapy (ART) is highly effective in suppressing HIV replication. HIV disease is now a chronic condition and causes of death in this population have shifted from traditional AIDS-related illnesses to non-AIDS (Acquired Immune Deficiency Syndrome) events, the most common being atherosclerotic cardiovascular disease, liver disease, end-stage renal disease and non-AIDS–defining malignancies. There are a diverse range of nutritional conditions associated with HIV, reflecting the complexity of the disease and pharmacological management....

Latent Tb Infection

The synergy between Mycobacterium tuberculosis (Mtb) and HIV in coinfected patients has profoundly impacted global mortality because of tuberculosis (TB) and AIDS. HIV significantly increases rates of reactivation of latent TB infection (LTBI) to active disease, with the decline in CD4+ T cells believed to be the major causality. In this study, nonhuman primates were coinfected with Mtb and simian immunodeficiency virus (SIV), recapitulating human coinfection. A majority of animals exhibited rapid reactivation of Mtb replication, progressing to disseminated TB and increased SIV-associated pathology. Although a severe loss of pulmonary CD4+ T cells was observed in all coinfected macaques, a subpopulation of the animals was still able to prevent reactivation and maintain LTBI. Investigation of pulmonary immune responses and pathology in this cohort demonstrated that increased CD8+ memory T-cell proliferation, higher granzyme B production, and expanded B-cell follicles correlated with protection from reactivation. Our findings reveal mechanisms that control SIV- and TB-associated pathology. These CD4-independent protective immune responses warrant further studies in HIV coinfected humans able to control their TB infection. Moreover, these findings will provide insight into natural immunity to Mtb and will guide development of novel vaccine strategies and immunotherapies.

Antiretroviral therapy (ART) effectively reduces cycles of viral replication but does not target proviral populations in cells that persist for prolonged periods and that can undergo clonal expansion. Consequently, chronic human immunodeficiency virus (HIV) infection is sustained during ART by a reservoir of long-lived latently infected cells and their progeny. This proviral landscape undergoes change over time on ART. One of the forces driving change in the landscape is the clonal expansion of infected CD4 T cells, which presents a key obstacle to HIV eradication. Potential mechanisms of clonal expansion include general immune activation, antigenic stimulation, homeostatic proliferation, and provirus-driven clonal expansion, each of which likely contributes in varying, and largely unmeasured, amounts to maintaining the reservoir. The role of clinical events, such as infections or neoplasms, in driving these mechanisms remains uncertain, but characterizing these forces may shed light on approaches to effectively eradicate HIV. A limited number of individuals have been cured of HIV infection in the setting of bone marrow transplant; information from these and other studies may identify the means to eradicate or control the virus without ART. In this review, we describe the mechanisms of HIV-1 persistence and clonal expansion, along with the attempts to modify these factors as part of reservoir reduction and cure strategies.

Context.— With increasing use and efficacy of antiretroviral therapy for human immunodeficiency virus (HIV) infection, deaths from acquired immunodeficiency syndrome (AIDS)–defining conditions have decreased. Objective.— To examine trends in the cause of death of HIV-infected patients who underwent autopsy at a major New York City hospital from 1984 to 2016, a period including the major epochs of the AIDS epidemic. Design.— Retrospective review of autopsy records and charts with modeling of trends by logistic regression using polynomial models. Results.— We identified 252 autopsies in adult patients with AIDS (by 1982 definition) or HIV infection. Prior to widespread use of highly active antiretroviral therapy, in 1984–1995, on average 13 autopsies per year were done. Post–highly active antiretroviral therapy, the average number of autopsies declined to 4.5 per year. The fitted mean age at death was 35 years in 1984 and increased curvilinearly to 46 years (95% CI, 43–49) in 2016 (P < .001). By regression analysis, mean CD4+ T-cell count increased from 6 in 1992 to 64 in 2016 (P = .01). The proportion of AIDS-defining opportunistic infections decreased, from 79% in 1984–1987 to 41% in 2008–2011 and 29% in 2012–2016 (P = .04). The frequency of nonopportunistic infections, however, increased from 37% in 1984–1987 to 73% in 2008–2011 and 57% in 2012–2016 (P = .001). The frequency of AIDS-defining and other malignancies did not change significantly during the study period. The prevalence of atherosclerosis at autopsy rose dramatically, from 21% in 1988–1991 to 54% in 2008–2011 (P < .001). Conclusions.— Despite limitations of autopsy studies, many trends in the evolution of the HIV/AIDS epidemic are readily discernable.

Human immunodeficiency virus (HIV) interacts with the immune system throughout the course of infection. For most of the disease process, HIV activates the immune system, and the degree of activation can be assessed by measuring serum levels of molecules such as beta 2-microglobulin and neopterin, as well as other serum and cell surface phenotype markers. The levels of some of these markers correlate with clinical progression of HIV disease, and these markers may be useful as surrogate markers for development of clinical AIDS. Because the likelihood and timing of development of clinical AIDS following seroconversion, for any particular individual, are not readily predictable, the use of nonclinical disease markers has become critically important to patient management. Surrogate markers of HIV infection are, by definition, measurable traits that correlate with disease progression. An ideal marker should identify patients at highest risk of disease progression, provide information on how long an individual has been infected, help in staging HIV disease, predict development of opportunistic infections associated with AIDS, monitor the therapeutic efficacy of immunomodulating or antiviral treatments, and the easily quantifiable, reliable, clinically available, and affordable. This review examines the current state of knowledge and the role of surrogate markers in the natural history and treatment of HIV infection. The clinical usefulness of each marker is assessed with respect to the criteria outlined for the ideal surrogate marker for HIV disease progression.

We report a novel case of severe bilateral panuveitis with hypopyon secondary to rifabutin and cobicistat drug interaction in the setting of human immunodeficiency virus (HIV) infection and latent tuberculosis (TB). A 63-year-old woman presented with bilateral conjunctival injection and decreasing vision of 5 days’ duration. She had a history of well-controlled HIV infection, latent TB, and non-alcoholic steatohepatitis for which she was inadvertently being treated, due to a pharmacy error, concurrently with the anti-TB medicine rifabutin and the highly active antiretroviral therapy combination Genvoya® (elvitegravir 150 mg – cobicistat 150 mg – emtricitabine 200 mg – tenofovir alafenamide 10 mg). Ocular examination was significant for bilateral panuveitis with hypopyon. Blood, cerebrospinal fluid, and vitreous analysis were negative for infectious or rheumatologic abnormalities. Rifabutin was discontinued and the patient was treated with intravenous followed by oral steroids as an outpatient with eventual resolution of symptoms. This unique case of rifabutin-cobicistat drug interaction highlights the association between rifabutin drug levels and ocular inflammation and expands the potential presentation of rifabutin-associated uveitis to include bilateral panuveitis with hypopyon.
