BACKGROUND: The specificity of nucleic acid amplification tests (NAATs) used for early infant diagnosis (EID) of HIV infection is <100%, leading some HIV-uninfected infants to be incorrectly identified as HIV-infected. The World Health Organization recommends that infants undergo a second NAAT to confirm any positive test result, but implementation is limited. Our objective was to determine the impact and cost-effectiveness of confirmatory HIV testing for EID programmes in South Africa...

Background: Although there is increased attention on the role of trained traditional birth attendants (TBAs) in maternal care, most of the research has mainly focused on providing evidence of the relevance of trained TBAs to women in general without a specific focus on women who are HIV positive, despite them being most vulnerable. Therefore, the aim of this study is to fill this gap by assessing the relevance of trained TBAs to women living with HIV in resource-poor settings by using Zambia as a case study...

HIV-1 infection and methamphetamine (METH) abuse frequently occur simultaneously and may have synergistic pathological effects. Although HIV-positive/active METH users have been shown to have higher HIV viral loads and experience more severe neurological complications than non-users, the direct impact of METH on HIV infection and its link to the development of neurocognitive alternations are still poorly understood. In the present study, we hypothesized that METH impacts HIV infection of neural progenitor cells (NPC) by a mechanism encompassing NFκB/SP1-mediated HIV-LTR activation...

Modulation of host immunity in invasive fungal infection is an appealing but as yet mostly elusive treatment strategy. Animal studies in invasive candidiasis and aspergillosis have demonstrated beneficial effects of colony stimulating factors, interferon-gamma and monoclonal antibodies. More recent studies transfusing leukocytes pre-loaded with lipophilic anti-fungal drugs, or modulated T-cells, along with novel vaccination strategies show great promise. The translation of immune therapies into clinical studies has been limited to date but this is changing and the results of new Candida vaccine trials are eagerly awaited...

The picture of human immunodeficiency virus (HIV)-infected patients has changed dramatically since the original description in 1981. The introduction of antiretroviral drugs in 1987 and combination antiretroviral therapy has decreased mortality by as much as 80%. We now see patients in their 60s and 70s, having lived decades with HIV and living a normal live. As outlined in the article, despite good viral control, patients with HIV may present with solid organ cancers earlier than noninfected patients and are also prone to other complications of their disease that may require the attention of a thoracic surgeon...

Sporotrichosis is a human and animal disease caused by species of the Sporothrix schenckii complex. It is classically acquired through traumatic inoculation of fungal elements. Most frequently, sporotrichosis presents as a fixed cutaneous or as a lymphocutaneous form. A much smaller number of cases occur as cutaneous disseminated and disseminated forms. These cases require immediate diagnosis and management to reduce morbidity and mortality. We present the case of a 34-year-old male patient in whom the first presentation of HIV infection was a rapidly progressive sporotrichosis with multiple cutaneous lesions, a high fungal burden in tissues, and pulmonary involvement...

BACKGROUND: Approximately 8% of HIV-infected individuals are co-infected with hepatitis B virus (HBV) in sub-Saharan Africa (SSA). Knowledge of HBV status is important to guide optimal selection of antiretroviral therapy (ART) and monitor/prevent liver-related complications. We describe changes in testing practices and management of HBV infection over a 3-year period in HIV clinics across SSA. METHODS: A medical chart review was conducted in large urban HIV treatment centers in Côte d'Ivoire (3 sites), Benin, Burkina Faso, Cameroon, Kenya, Senegal, South Africa, Togo, Uganda and Zambia (1 site each)...

BACKGROUND: Individual-level simulation models are valuable tools for comparing the impact of clinical or public health interventions on population health and cost outcomes over time. However, a key challenge is ensuring that outcome estimates correctly reflect real-world impacts. Calibration to targets obtained from randomized trials may be insufficient if trials do not exist for populations, time periods, or interventions of interest. Observational data can provide a wider range of calibration targets but requires methods to adjust for treatment-confounder feedback...

In the era of Antiretroviral Therapy (ART) in which human immunodeficiency virus type 1 (HIV-1) infection affected children can expect a better prognosis, the importance of careful follow up of pediatric HIV-1 cases for neurological complications has been growing. We present a case of hemorrhagic Moyamoya syndrome in a child with congenital HIV-1 infection. A 10-year-old girl was referred to our hospital for the treatment of Pneumocystis Jirovecii Pneumonia (PCP: Pneumocystis pneumonia). Her HIV-1 control was poor and Moyamoya syndrome was found during the opportunistic infection screening at admission...

In 2016, WHO adopted a strategy for the elimination of viral hepatitis by 2030. Africa, and more specifically, sub-Saharan Africa, carries a substantial portion of the global burden of viral hepatitis, especially chronic hepatitis B and hepatitis C virus infections. The task that lies ahead for sub-Saharan Africa to achieve elimination is substantial, but not insurmountable. Major developments in the management of hepatitis C have put elimination within reach, but several difficulties will need to be navigated on the path to elimination...

While effective antiretroviral treatment makes human immunodeficiency virus (HIV)-related death decreased dramatically, neuropathic pain becomes one of the most common complications in patients with HIV/acquired immunodeficiency syndrome (AIDS). The exact mechanisms of HIV-related neuropathic pain are not well understood yet, and no effective therapy is for HIV-pain. Evidence has shown that proinflammatory factors (e.g., tumor necrosis factor alpha (TNFα)) released from glia, are critical to contributing to chronic pain...

Allogeneic hematopoietic stem cell transplantation (HSCT) is a critically important therapy for hematological malignancies, inborn errors of metabolism, and immunodeficiency disorders, yet complications such as graft-vs.-host disease (GvHD) limit survival. Development of anti-GvHD therapies that do not adversely affect susceptibility to infection or graft-vs.-tumor immunity are hampered by the lack of a physiologically relevant, preclinical model of allogeneic HSCT. Here we show a spectrum of diverse clinical HSCT outcomes including primary and secondary graft failure, lethal GvHD, and stable, disease-free full donor engraftment using reduced intensity conditioning and mobilized peripheral blood HSCT in unrelated, fully MHC-matched Mauritian-origin cynomolgus macaques...

The emergence of drug-resistant tuberculosis has generated great concern in the control of tuberculosis and HIV/TB patients have established severe complications that are difficult to treat. Although, the gold standard of drug-susceptibility testing is highly accurate and efficient, it is time-consuming. Diagnostic biomarkers are, therefore, necessary in discriminating between infection from drug-resistant and drug-susceptible strains. One strategy that aids to effectively control tuberculosis is understanding the function of secreting proteins that mycobacteria use to manipulate the host cellular defenses...

BACKGROUND: The expected value of sample information (EVSI) can help prioritize research but its application is hampered by computational infeasibility, especially for complex models. We investigated an approach by Strong and colleagues to estimate EVSI by applying generalized additive models (GAM) to results generated from a probabilistic sensitivity analysis (PSA). METHODS: For 3 potential HIV prevention and treatment strategies, we estimated life expectancy and lifetime costs using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) model, a complex patient-level microsimulation model of HIV progression...

BACKGROUND: Despite global health efforts to reduce maternal mortality, rates continue to be unacceptably high in large parts of the world. Feasible, acceptable, and accurate postmortem sampling methods could provide the necessary evidence to improve the understanding of the real causes of maternal mortality, guiding the design of interventions to reduce this burden. METHODS AND FINDINGS: The validity of a minimally invasive autopsy (MIA) method in determining the cause of death was assessed in an observational study in 57 maternal deaths by comparing the results of the MIA with those of the gold standard (complete diagnostic autopsy [CDA], which includes any available clinical information)...

Human cytomegalovirus (HCMV), a herpesvirus, is an important human pathogen that causes asymptomatic infections in healthy or immunocompetent individuals but can lead to severe and potentially life-threatening complications in immune-immature individuals such as neonates or immune-compromised patients such as organ-transplant recipients and HIV-positive individuals. Congenital HCMV infection represents a significant public health issue and poses substantial healthcare and economic burden to society. This virus causes the most common viral congenital infection worldwide, and is the leading non-genetic cause of sensorineural hearing loss in children in developed countries...

Confidentiality is a basic concept in medical ethics and protecting confidentiality is considered as physicians' duty. In some occasions, this protection is in conflict with the right of the patient's sexual partner, who should be informed about the possibility of being infected. The sexual partner being pregnant, the situation is going to be more complicated. In this paper, we present a case discussion with special ethical, legal, social, cultural, and religious aspects. According to this informing sexual partner with the patient's assent, opt-out Human immunodeficiency virus (HIV) screening in pregnant women and enhancing psychosocial and family support are highly recommended...

Randomized trials have shown that voluntary medical male circumcision (VMMC) significantly reduces the risk of HIV acquisition in men. However, the rate of complications associated with the surgical procedure varies from 0.7% to 37.4% in real-world settings. We assessed the frequency, type and severity of adverse events following VMMC among 427 adult men surgically circumcised in southeastern Botswana; 97% completed ≥1 follow-up visit within seven days post-circumcision. Thirty moderate AEs were observed in 28 men resulting in an overall AE rate of 6...
