Gj. Ruizarguelles et al., SURVIVAL OF PATIENTS WITH ADVANCED HIV-INFECTION TREATED WITH 300 MG D OF ZIDOVUDINE - A PROSPECTIVE-STUDY/, Revista de Investigacion Clinica, 46(6), 1994, pp. 491-493
In this prospective study we analyze the long-term survival using 300
mg/day zidovudine (AZT) in patients with advanced forms of human immun
odeficiency virus infection. The study is in a private-practice settin
g, over a 5-year period, and includes 72 patients with advanced human
immunodeficiency virus infection (categories C1, 2 or 3). The median s
urvival (SV) is above 60 months (24-months SV 65% and 60-month SV 54%)
. According to the number of CD4 cells at diagnosis it was found that
patients with above or below 200 CD4 T cells had a median SV of above
60 and 18 months (p < 0.001) and a 24-month SV 88 and 45% (p < 0.001);
for patients with CD4 cells below 20 at diagnosis, the median surviva
l was even lower (three months) and the 12-month survival less than 18
%. It is concluded that the results of treating HIV-infected patients
with AZT 300 mg/day are similar to those reported by others using high
er doses of AZT. A low dosage is also more easily available to a large
r number of HIV-infected individuals.
