Additional information on preventing and treating KS-IRIS is warranted including optimal timing of cART initiation for patients who present with extensive skin lesions and lung involvement, the impact of HIV and HHV-8/KSHV viral loads and CD4/CD8 counts as well as the production of inflammatory cytokines in diverse clinical scenarios as well as the role that other co-infections may have on the development of KS [55]. Here, CD4 is linked to Kaposi's sarcoma.
