Changing spectrum of HIV infection and its associated conditions in Spain: the end of the beginning?

| Abstract |
To evaluate the natural history and the impact that different strategies have had on HIV infection and its associated conditions, a cohort of 970 patients (432 had AIDS) who had been seen over a period of 13 years were studied. The incidence of new HIV-infected patients had increased steadily since 1985, peaking in 1993 (52.9 cases/100,000 population), to significantly decrease in the subsequent years. The most common AIDS-defining illnesses (ADIs) were tuberculosis (52.3% of the patients), Pneumocystis carinii pneumonia (30%), and candidal esophagitis (28.6%). The frequency of new cases of tuberculosis per patient with ADI clearly decreased over this period (p < 0.0001), whereas that of P. carinii pneumonia decreased slowly until 1994, to fall thereafter to about half the previous levels (p = 0.005). Candidal esophagitis showed a biphasic pattern, the second peak probably due to the emergence of fluconazole resistance. The number of ADIs per patient increased from the beginning of the observation period, peaking in 1995 (1.67 ADI/patient), followed by a statistically significant decrease that, in 1997, reached the 1987 levels (1.22 ADI/patient). We conclude that the clinical spectrum of HIV infection is improving in the last years. Except for tuberculosis, prophylaxis for other ADIs, although effective, does not seem to have had a dramatic impact on occurrence. The most impressive reductions have been observed only after the introduction of antiretroviral combination therapy.
