“…infection, as the immunosuppression caused by HIV infection facilitates the pathogenesis of Mycobacterium infection. INAAs caused by Mycobacteria are uncommon in patients without HIV but has been reported [52]. This reflects the degrading effect of HIV on the immune system, with risk of a variety of different OIs.…”

HIV‐associated infective native aortic aneurysms (INAA) constitute a subcategory of the disease INAA. This is a very rare group of patients. The aim of this systematic literature review was to compile a description of patient characteristics with HIV‐associated INAA. A systematic literature review was performed using the search terms HIV and aortic aneurysm in Ovid MEDLINE and Embase databases, on articles published between 1981 and 2022. Using the Preferred Reporting Items for Systematic reviews and Meta‐Analyses (PRISMA) statement, articles were scrutinized according to a predefined protocol including age, sex, comorbidities, microbiological pathogens, CD4‐count, HIV/AIDS state, aortic segment involved, treatment and outcome. Thirty‐three studies, all case reports with a total of 39 patients, were included. The median age was 48 years (range 27–79), most were male n = 35 (90%), and the median follow‐up was n = 6 months (range 0–63). Cardiovascular comorbidity was present in n = 1 (3%), median CD4‐count was 216 (range 6–1236), and n = 12 (31%) had AIDS. The most common microbiological pathogens were Treponema pallidum, n = 12 (31%), Salmonella spp. n = 10 (26%), Mycobacterium species n = 5 (12%) and Staphylococcal spp. n = 5 (13%). The HIV‐associated INAAs were localized in the abdominal aorta n = 32 (82%), in the thoracic aorta n = 5 (13%) and in the thoraco‐abdominal aorta n = 2 (5%). Open surgery was performed in n = 23 (59%) patients, endovascular aortic repair n = 6 (15%), and n = 7 (18%) did not receive surgery. Infection‐related complications were reported in n = 2 (7%) patients, both with postoperative development of fatal sepsis. Patients with HIV‐associated INAAs were younger, had lower rate of cardiovascular comorbidity, demonstrated low CD4 counts as a measure of immunosuppression, and demonstrated diverse microbiological pathogens compared with other INAAs. Treponema pallidum and Mycobacterium spp. were common pathogens, which are very rare microbiological pathogens in other INAAs.
