In this presentation data was presented proving that it is safe to discontinue PCP prophylaxis in HIV-positive people who have had PCP in the past, but are on effective HAART therapy and have experienced a rise in CD4 cells to above 200. The extensive study, which included eight study sights around Europe, included 236 patients (of which 14% were women) who had a previous history of PCP. Follow-up after stopping the prophylaxis for PCP ranged from five to thirteen months, and during this time there was no recurrence of PCP in any of the patients in the study.
The conclusion from this study is that among patients who experience a CD4 rise to above 200 and who have effective viral suppression resulting from HAART; it is safe to discontinue PCP prophylaxis. Doing so will reduce the pill burden on many people and reduce the costs associated with long-term treatment of HIV without compromising the quality of care being provided. Accordingly, CDC guidelines need to be changed to reflect the findings of this study and expand their recommendations for when to discontinue PCP prophylaxis to include patients with a history of PCP, but who have CD4 counts over 200 coupled with effective viral suppression.
