Updated project metadata. The retrospective cohort study was focused on the first line ART patients who were enrolled in the antiretroviral therapy center, Sarojini Naidu Medical College, Agra, India from December 2009 to November 2016. The main criteria for inclusion was based on the immunological marker, i.e. CD4+ count (<350). The all age group adults and adolescents were included in this study. The informed consents were obtained from all patients. A patient information leaflet was used for collection of sociodemographic and clinical profile data. This study protocol was approved by Institute human ethics committee. The Institute ethics committee is constituted as per the guidelines directed by Indian Council of MedicalResearch. Ten ml of blood samples were collected from a total of six AIDS patients after counselling whose CD4+ count was <350 cells/µl. Then plasma was separated by centrifugation at 2000g for 10 minutes. Then plasma was stored at -800C for estimation of viral load and genotyping was carried out at NIRT, ICMR, Chennai, Tamilnadu, India.The viral load was estimated using Abbott automated m2000rt instrument. Those who were having>1000 copies/ml called as a drug resistant and < 1000 copies/ml called as drug responder. Among them, 3 patients were having high viral load >1000 copies/ml (drug resistant and 3 patients were with <1000 copies/ml (drug responder). The 3 treatment failure (>1000 copies/ml) samples were further considered for genotype analysis. Highly abundant proteins (Albumin and IgG) were depleted using the Aurum–Serum protein mini kit (Biorad, USA). The depleted plasma samples were analyzed in SWATH-MS. Then, the proteins were identified and characterized using the SWATH analysis.
