“…At baseline, the main DRV-associated mutations were 33F (n ¼ 56, 32.4%), 84V (n ¼ 33, 19.1%), 32I (n ¼ 23, 13.3%), 47V (n ¼ 20, 11.6%) and 54L (n ¼ 20, 11.6%) ( Figure 1). Forty-seven per cent (n ¼ 82) of the patients were predicted to be susceptible to DRV/r, 9.2% (n ¼ 16) had potential low-level resistance, 23 Eighty-seven per cent of the patients (n ¼ 155) were on a PI regimen prior to the initiation of DRV/r associated with an OBR. The median number of PI mutations was 4 (range, 2-6), and 83.8% (n ¼ 145) of the patients had three or more PI mutations.…”

“…15,17 In São Paulo, Brazil, a recent study by our group at another tertiary centre showed that DRV/r plus an OBR use had an effectiveness of 71% after long term follow-up, demonstrating long-term persistent virological suppression. 23 None of these studies with extended follow-up assessed the factors associated with virological suppression or failure. 15,17,23 It is important to emphasize that PLWH in the present study had a worse resistance profile to DRV/r and more PI and DRV/r mutations than the patients in the Pernas et al 17 and Vidal et al longterm studies.…”

“…87 Variações entre a efetividade nos diversos estudos estão possivelmente associadas às características epidemiológicas, clínicas e genotípicas entre os grupos de pacientes estudados. É importante enfatizar que no presente trabalho, os pacientes apresentam pior perfil de sensibilidade ao DRV/r e mais mutações de resistência aos IP e ao DRV/r, que em outros estudos de longo seguimento 58,87 Resumo dos principais estudos observacionais, nacionais e internacionais, pode ser visto no Quadro 3.…”

“…***Os casos deste estudo são os mesmos incluídos no estudo de Vidal et al44 longo histórico de infecção por HIV, em 48 semanas de seguimento, tendo resultados de 71 a 135,9 células/mm³ entre eles 44,52,54,56,58,83 Em seguimentos mais prolongados, como nos estudosde Antinori et al (96 semanas) e Vidal et al (sete anos), variações médias de 138 e 353,3 células/mm³ foram encontradas, respectivamente. 59,87 Em relação à análise em 144 semanas, comparativamente com nosso estudo, Vidal et al, em sua coorte de longo seguimento, observaram uma variação média de 258,4 células/mm³.…”
