Highly active antiretroviral therapy (HAART) reduces the incidence and improves the prognosis of Kaposi's sarcoma (KS). This study was designed to identify factors associated with KS clinical responses in HIV-infected patients during HAART. We reviewed the files of 138 HIV-1-infected patients with KS. Epidemiologic and HIV-related clinical and biological parameters were recorded at KS diagnosis (baseline) and every 6 months thereafter. In a subset of 73 antiretroviral-naive patients, we compared the clinical outcome of KS according to the use or nonuse of protease inhibitors (PI). After 6 months of follow-up, KS remission was more frequent in patients who were naive of HAART and who were at ACTG stage S0 at baseline (P ¼ 0.03 and 0.02). Undetectable HIV viral load was strongly associated with KS remission (Pp0.004 at all time points), while CD4 cell count was not. Among the 73 antiretroviralnaive patients at baseline, and who were studied for 24 months, KS outcome did not differ between patients who were prescribed PIcontaining and PI-sparing regimens. Intercurrent multicentric Castleman's disease was associated with poor outcome after 60 months of follow-up (Pp0.0001). Fourteen deaths occurred after a median follow-up of 37.5 months, eight of which were KS related. Suppression of HIV replication appears to be crucial to control KS. Non-PI-based regimens were equivalent to PI-based regimens as regards the clinical and virological outcome of antiretroviral-naive HIV-infected patients with KS.
Background: Anti-tumor necrosis factor (TNF) agents are increasingly being used for a rapidly expanding number of rheumatic and systemic diseases. As a result of this use, and of the longer follow-up periods of treatment, there are a growing number of reports of the development of autoimmune processes related to anti-TNF agents. The use of anti-TNF agents has been associated with more and more cases of autoimmune diseases, principally cutaneous vasculitis, lupus-like syndrome, systemic lupus erythematosus and interstitial lung disease. Observations: We report 2 cases of autoimmune bullous skin disease occurring in patients undergoing TNF-targeted therapy: a bullous pemphigoid and a pemphigus foliaceus. Both patients were treated by anti-TNF agents for rheumatoid arthritis and showed improvement following interruption of that treatment. Here, we discuss the relationship between anti-TNF therapy and the occurrence of autoimmune bullous disease. Conclusion: Anti-TNF agents should be considered as a potential cause of drug-induced autoimmune bullous skin disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
