Sir,

Su et al. described nicely the clinical picture and management plan of renal vein aneurysm (RVA) in a Taiwanese patient.[1] It is noteworthy that there is an established relationship between human immunodeficiency virus (HIV) and the vascular system, which is characterized by the clinical expressions of aneurysmal and occlusive disease emanating from a common pathological process. The exact pathogenesis is currently unknown. However, evidence pointed out to leukocytoclastic vasculitis with the vaso vasora as the vasculopathic epicenter.[2] It was postulated that the virus itself or viral proteins could trigger the release of inflammatory mediators causing endothelial dysfunction and smooth muscle proliferation leading to vascular injury, aneurysmal dilatation, and thrombosis.[2] Actually, HIV-related aneurysmal vasculopathy has been reported among HIV-positive patients.[3] To my knowledge, HIV infection is an important health problem in Taiwan. Although no recent data are yet present on the exact HIV seroprevalence in Taiwan, the available data pointed out that by the end of 2016, the total number of HIV cases had been accumulated to 33,423 (15,418 of whom had developed full-blown AIDS and 5569 cases had deceased).[4] I presume that underlying HIV infection ought to be considered in the studied patient. Hence, arrangement for the diagnostic panel of viral overload and CD4 count estimations was solicited. If that diagnostic panel was performed and it revealed HIV infection, the case in question could be surely regarded a novel case report. This is because HIV-associated RVA has never been reported in the published literature so far.
