Subject: "Preventing Opportunistic Infections in HIVInfected Injection Drug Users" Source: Journal of the American Medical Association (12/03/97) Vol. 278, No. 21, P. 1743; Kaplan, Jonathan E.; Jaffe, Harold W.; Masur, Henry; et al. Jonathan E. Kaplan and Harold W. Jaffe of the Centers for Disease Control and Prevention and colleagues have written a response to a letter to the editor in the Journal of the American Medical Association. In their response, they write that the letterwritten by David C. Perlman and colleaguesraises two issues relevant to the U.S. Public Health Service/Infectious Diseases Society of America guidelines on the prevention of opportunistic infections in HIVpositive persons. In both 1995 and 1997, the authors note, the scope of the guidelines was limited to the opportunistic infections of greatest importance in HIVpositive individuals. Perlman's letter, however, addresses the risks of infectious diseases among HIVpositive intravenous drug users, a population with a fastgrowing HIV infection rate. This raises questions regarding the inclusion of such diseases in the guidelines. Additionally, Kaplan et al. note, Perlman's letter raises questions about the system used to rate the strength of diseasespecific recommendations in the guidelines and the quality of evidence supporting those recommendations. In conclusion, the authors agree with Perlman that the infection risks and prevention methods associated with intravenous drug use, especially those that meet the definition of opportunistic infections, such as bacterial endocarditis, should be included in future editions of the guidelines. Nonopportunistic, riskgroup specific infections that are also transmitted through sexual contactsuch as syphilis, gonorrhea, chlamydia, giardiasis, and hepatitis A and Bshould also be included.
