But with no millions and vaccine of people holding the virus or becoming newly infected, some researchers said ending HIV could be idealistic rather than practical. We’ve made progress, but the amount of people getting infected is extraordinarily high still, said Shabbar Jaffar, a professor of epidemiology at the London College of Hygiene and Tropical Medicine. He said that further scaling up treatment, especially in Africa, where about 70 % of people with HIV live, would be very hard.If the score on the DAS28 decreased by significantly less than 1.2, the participant was switched to the choice regimen. Sulfasalazine could be reduced to 500 mg twice a day if a participant acquired unacceptable side effects with the bigger dose. Participants were seen every 6 weeks for monitoring of laboratory values and adverse events. At the time of enrollment and every 12 weeks, the Health Assessment Questionnaire II27 was administered, a count of joints with disease activity was performed, and pain was assessed.
