“…[ 36 , 37 ] Some studies showed a weak antibody response in a proportion of patients with early ART and fewer patients starting ART in chronic HIV infection. [ 38 ] In addition, patients with long-term suppressive ART still had continuous antigenic stimulation and lead to the evolution of HIV-specific antibody. [ 37 ] In our study, patients with VF prior to switch might have different HIV-specific antibody responses compared with patients without VF, further study should focus on the trend of antibody responses to HIV and give some hints to HIV incidence surveillance and vaccine development.…”

Background: Previous studies have shown low frequencies of seroreactivity to HIV diagnostic assays for infected infants treated with antiretroviral therapy (ART) early in infection. Methods: Fifty-eight HIV-infected infants treated with ART at a median age of 1.9 months (range: 0.2–5.4) for up to 4 years of life were assessed for seroreactivity to 4 routinely used HIV clinical immunoassays (IA): Second-generation (2ndG) IA and 2 rapid diagnostic tests (RDT), based on third-generation principles, measuring antibody only and a fourth-generation (4thG) antigen/antibody IA. HIV Western blot assay was also performed to assess HIV-specific antibodies. Results: The 2ndG IA demonstrated the highest frequency of seroreactivity in children (69%) followed by the 4thG IA (40%) and the RDT (26%) after one year of ART. Infants initiating ART during ages 3–6 months (N = 15) showed a greater frequency (range: 53%–93%) and breadth (median and range: 3 [1–4]) of reactivity across the assays compared with those treated within 3 months (N = 43):16%–61% and breadth (1 [0–4]). The 4thG IA showed significantly reduced reactivity relative to the 2ndG IA at one (P = 0.016) and 3 (P = 0.004) years of ART. Western blot profiles following 3 years of ART showed the highest frequency of reactivity to HIV Gag p24 (76%) and lowest reactivity to Env gp120 and gp41, with only 24% of children confirmed positive by the assay. Conclusions: These results suggest that the use of 4thG IA and RDT test combination algorithms with limited HIV antigen breadth may not be adequate for diagnosis of HIV-infected children following early treatment.
