Is HIV a Model of Accelerated or Accentuated Aging?

Abstract: There is a need for validated biomarkers of aging in the context of HIV. Despite these differences, welldesigned studies of HIV-infected participants are likely to provide new opportunities to better understand the mechanisms that lead to aging and age-related diseases.

“…11 The term immunosenescence refers to age-related changes in both the innate and adaptive immune systems associated to morbidity and mortality and reduction in vaccines responses. 7,14,15 In older adults, these changes seem to be linked to pro-inflammatory pathway (Inflamm-Aging), even if the mechanism is not completely understood (cellular damage? endogenous activators?…”

“…HIV and CMV chronic infections and the consequent inflammation and immune activation, the perturbation of T-cell compartment associated to the supposed role of CMV as "smoking gun" in immunosenescence, make the double infection play a synergic role in accelerated aging. 7,14,27,28 Finally, HIV infection causes the depletion of CD4C T-cells of gut-associated lymphoid tissue (GALT) both by HIV direct effect and by activation-induced cell death. The mucosa-associated damage, due to GALT depletion, promotes a persistent intestinal bacterial translocation which increases chronic inflammation.…”

“…7 Pada pasien tersebut, secara klinis dapat dijumpai sindroma geriatri seperti multi-morbiditas, frailty dan polifarmasi. 8 Baik karena proses penuaan yang dipercepat ataupun faktor gaya hidup, tingkat komorbid non-HIV yang terkait dengan HIV meningkat seiring dengan bertambahnya usia, setara jika dibandingkan dengan populasi yang tidak terinfeksi HIV yang berusia 10-15 tahun lebih tua. [8][9][10][11][12] teori dapat mempercepat proses penuaan.…”

“…8 Baik karena proses penuaan yang dipercepat ataupun faktor gaya hidup, tingkat komorbid non-HIV yang terkait dengan HIV meningkat seiring dengan bertambahnya usia, setara jika dibandingkan dengan populasi yang tidak terinfeksi HIV yang berusia 10-15 tahun lebih tua. [8][9][10][11][12] teori dapat mempercepat proses penuaan. 15,16 Selain itu, pada pasien HIV yang belum mendapat terapi ARV, serta pada pasien HIVusia lanjut dijumpai hal-hal sebagai berikut: 1) ekspresi limfosit T dan cyclin-dependent kinase inhibitor 2A (CDKN2A); 2) akumulasi sel T CD28-CD8+; 3) berkurangnya generasi sel T naif; 4) sel T repertoire yang rendah; 5) rasio CD4+/CD8+ yang rendah; 6) ekspansi efektor sel T CD28; 7) kurangnya respons terhadap vaksin; dan 8) berlangsungnya aktivasi sistem imun yang terjadi terus menerus.…”
