RT Journal A1 Famularo G, De Simone C, Cifone G T1 CArnitine stands on its own in hiv infection treatment JF Archives of Internal Medicine JO Archives of Internal Medicine YR 1999 FD May 24 VO 159 IS 10 SP 1143 OP 1144 DO UL http://dx.doi.org/ AB We read with great interest the recent article by Fairfield and colleagues.1 We agree with their conclusions that appropriate investigations are necessary to establish with confidence the benefit or risk associated with the use of complementary and alternative medicine by persons infected with the human immunodeficiency virus (HIV). However, our experience is that the investigation of unconventional therapies is regarded as trivial by most researchers and, consequently, high-quality scientific evidence that clearly establishes the effectiveness (or lack thereof) of these interventions is lacking.
