Article Abstract
Background: There are few recent data on the rates of AIDS-defining opportunistic infections (OIs) among human immunodeficiency virus (HIV)-infected patients in care in the United States and Canada.
Methods: We studied HIV-infected participants in 16 cohorts in the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) during 2000-2010. After excluding 16 737 (21%) with any AIDS-defining clinical events documented before NA-ACCORD enrollment, we analyzed incident OIs among the remaining 63 541 persons, most of whom received antiretroviral therapy during the observation. We calculated incidence rates per 100 person-years of observation (hereafter, "person-years") with 95% confidence intervals (CIs) for the first occurrence of any OI and select individual OIs during 2000-2003, 2004-2007, and 2008-2010.
Results: A total of 63 541 persons contributed 261 573 person-years, of whom 5836 (9%) developed at least 1 OI. The incidence rate of any first OI decreased over the 3 observation periods, with 3.0 cases, 2.4 cases, and 1.5 cases per 100 person-years of observation during 2000-2003, 2004-2007, and 2008-2010, respectively (Ptrend<.001); the rates of most individual OIs decreased as well. During 2008-2010, the leading OIs included Pneumocystis jiroveci pneumonia, esophageal candidiasis, and disseminated Mycobacterium avium complex or Mycobacterium kansasii infection.
Conclusions: For HIV-infected persons in care during 2000-2010, rates of first OI were relatively low and generally declined over this time.

Disseminated Mycobacterium avium complex (DMAC) infection is a major AIDS-defining condition with diagnostic challenges due to nonspecific symptoms. This study, for the first time in Iran, aimed to discriminate MAC organisms in 100 HIV-positive patients directly from clinical specimens and assess their clinical significance, epidemiological characteristics, and associated risk factors through a detailed review of medical and demographic records. Clinical specimens (blood, sputum, and stool) were collected, and routine clinical evaluations were performed.

Antiretroviral therapy (ART) has transformed HIV from a rapidly progressive and fatal disease to a chronic disease with limited impact on life expectancy. However, people living with HIV(PLWHs) faced high critical illness risk due to the increased prevalence of various comorbidities and are admitted to the Intensive Care Unit(ICU). This study aimed to use machine learning to predict ICU admission risk in PLWHs.

The availability of combined antiretroviral therapy has significantly reduced the number of new HIV infections and the associated mortality, and HIV infection has become a chronic disease with long-term survival. In Korea, more than 1,000 new HIV infections have been registered annually since 2013. After peaking at 1,223 in 2019, the number of new infections decreased between 2020 and 2023.

Introduction: HIV late presentation, defined as a CD4+ cell count below 350 cells/μL or the presence of an AIDS-defining condition at diagnosis, represents a significant global challenge, accounting for approximately 50% new HIV diagnoses worldwide. This phenomenon is associated with suboptimal clinical outcomes, increased morbidity and mortality, and elevated transmission risks due to prolonged undiagnosed infection.
Areas Covered: This review examines the definitions, risk factors, epidemiology, and clinical implications of late presentation in HIV.
