Abstract
Late presentation to medical care of individuals infected with the human immunodeficiency virus (HIV) is linked to poor outcomes and increased morbidity and mortality. Missed opportunities for a prompt diagnosis are frequently reported among late presenters. We aimed to estimate the proportion of late presenters and missed opportunities in diagnosis among newly diagnosed HIV-positive subjects presenting to a specialty clinic in Lebanon. This is a retrospective chart review of all newly diagnosed adult HIV-positive subjects presenting to clinic from 2012 to 2022. Demographic, laboratory, and clinical data were collected at initial HIV diagnosis or presentation to medical care. We defined late presentation as having a CD4 count < 350 or AIDS-defining event regardless of CD4 count. Advanced disease is defined as having a CD4 count below 200 cells/μL or the presence of an AIDS-defining illness, regardless of the CD4 count. A missed opportunity was defined as the presence of an indicator condition (IC) that suggests infection with HIV/AIDS during 3 years preceding the actual HIV diagnosis and not followed by a recommendation for HIV testing. The proportions for demographic, epidemiological, and clinical characteristics are calculated by excluding cases with missing information from the denominator. Our cohort included 150 subjects (92.7% males; 63.6% men who have sex with men (MSM); 33.3% heterosexuals; median age 30.5 years at diagnosis). 77 (51.3%) were late presenters and 53 (35.3% of all subjects, 68.8% of late presenters) had advanced HIV on presentation. Up to 76.5% of late presenters had a presentation with an HIV-related condition at a healthcare provider without getting HIV test within the previous 3 years. The most frequent ICs were weight loss, generalized lymphadenopathy, constitutional symptoms, and chronic idiopathic diarrhea. Overall mortality rate was 4% (6/150 individuals). All-cause mortality among those who presented with AIDS was 15.4% (6/39 subjects). In our setting, late presentations and missed opportunities for HIV diagnosis are common. In the Middle East, AIDS mortality remains high with a large gap in HIV testing. To effectively influence policies, comprehensive analyses should focus on estimating the preventable health and financial burdens of late HIV presentations. Another concern pertains to healthcare providers' attitudes and competencies.
