As DMAC has a high mortality rate if not properly diagnosed and treated, we performed a literature review of HIV/AIDS and DMAC epidemiology, risk factors, prophylaxis, clinical manifestation, diagnosis, prognosis, and treatment.

We performed a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines to identify the factors that may affect the validity and reliability of HAC. This review included 25 studies that reported data on the associations of hair concentrations of 10 ARVs with 22 potential factors related to HAC. Notwithstanding scarce data and some inconsistencies, the data from existing studies suggested that (1) HAC was associated with hair types, hair segment position, housing, illegal drugs use, high-risk sexual behaviors, renal function, and genetic factors; (2) HAC was not associated with race/ethnicity, location of sample, ARV side effects, length of ARV treatment, smoking, alcohol use, orange consumption, depression, or anthropometry characteristics; and (3) the relationships of HAC with natural hair color, hair treatment, age, sex, dosing schedule, and liver function need further study. This review of factors related to HAC informed the design, analysis, and interpretation of the future HIV treatment and HIV prevention research utilizing hair concentrations of various ARVs as a biomarker of ARV adherence.

The virus is less transmissible than HIV-1, being sexual contacts the most frequent route of acquisition. In the absence of antiretroviral therapy, most HIV-2 carriers will develop AIDS; however, it takes longer than in HIV-1 infection. There is no global pandemic caused by HIV-2, as the virus is largely confined to West Africa. Due to historical ties, HIV-2 is also prevalent in Portugal and its former colonies in Brazil, India, Mozambique, and Angola. Other European countries with hundreds to thousands of HIV-2 infections are France, Belgium, and Spain. A few hundred have been reported in North America, mostly in West African foreigners. Globally, HIV-2 infections are steadily declining. Vorinostat manufacturer Although CD4 declines occur more slowly in HIV-2 than in HIV-1 patients, the CD4 recovery with antiretroviral treatment is smaller in the former. HIV-2 is naturally resistant to non-nucleoside viral therapy is warranted for either HIV-1 or HIV-2, given that it would protect from each other superinfection in persons at risk.

The advent of highly active antiretroviral therapy (HAART) has induced a marked reduction in the viral load and an increase in the CD4 cell count, thereby changing the course of the disease from an acute life-threatening condition to chronic disease. Accordingly, need and demand for oral rehabilitation in HIV positive population have increased in recent years. However, few drugs used in the HAART regimen have also known to be associated with osteopenia and osteoporosis. Although HAART reduces the morbidity in HIV patients, it remains unknown to what extent the therapy influences the implant healing. Few scientific literatures have identified osteoporosis and HIV infection as an unconducive milieu for dental implant placement and survival but demonstrated favorable outcomes in short-term assessments. The long-term impact of bone metabolic effects of HAART on implant success remains a conundrum.

Hence, the identification and characterization of these HIV-1 reservoirs were the focus of many studies during the past decades. In this review, a systematic literature screening and text mining approach were implemented to assess the evolution in experimental design of these HIV-1 reservoir studies. For this purpose, the online databases PubMed, Web of Science, and ClinicalTrials.gov were consulted and 1768 articles were identified, of which 106 are included in this review. We observed several evolutions that indicate a more structured approach of recent HIV-1 reservoir studies. This includes the use of well-characterized patient cohorts, tissue sampling at several time points and anatomical compartments, the inclusion of patients with different treatment status (on and off antiretroviral therapy), and the implementation of state-of-the-art research techniques such as single genome sequencing. In addition, there is an increased interest and sampling of lymphoid tissues and cerebrospinal fluid together with methods to investigate cellular subsets and HIV-1 sequences. Overall, this review describes an observed shift from detecting and quantifying HIV-1 toward a qualitative in-depth assessment of anatomical reservoirs and cellular subsets playing a role in HIV-1 persistence/latency. These trends coincide with the evolution in focus from controlling HIV-1 replication by currently available antiretroviral therapy toward HIV-1 curative strategies.

To inform services and policy development, we analyzed research growth and current trends in studies on children with HIV/AIDS. A total of 17,598 research papers and reviews in English, which were published on Web of Science, were downloaded. VOSviewer was used to generate an author keyword cooccurrence network and a network illustrating the connection among countries by shared coauthorships. Exploratory factor analysis was employed to identify research domains emerging from the abstracts' contents. The number of papers and their impacts had grown significantly in the past decade. The majority of study settings were in African countries. Research topics related to HIV in children were robust in areas of prevention of mother-to-child transmission and HIV and comorbidities treatments. Although psychosocial and behavioral disorders were recognized in previous studies, the number of interventions in these fields is still limited or not sustained.
