However, this adherence is far from being respected even by patients with serious pathologies such as patients living with HIV (PLWHIV). However, among PLWHIV, non-adherence is a significant source of virological failure and is difficult to assess because it is most often based on what the patient reports to their doctor. A currently used approach consists of determining the drug concentration in the blood and possibly that of its metabolite(s). However, determining a drug's blood concentration presents two major pitfalls: (i) it is necessary to take a blood sample, which remains an invasive procedure for the patient; (ii) for the vast majority of drugs, if the patient scrupulously adheres to the dosage schedule a few days before the blood sample is taken, the drug concentration is most often within the expected range. Therefore, a concentration in the reference range does not exclude partial or even total non-compliance between two medical visits. Saliva is a more easily accessible matrix than blood. However, the same representativeness problem is encountered due to the fact that saliva is in almost instantaneous equilibrium with blood.\n\nUrine could be used to assess compliance. However, this requires multiple urine collections between two doses. This constraint is not compatible with the organization of clinical services. The objective is to determine intra-individual variability in the amount of antiretroviral (ARV) in different segments of the same strand of hair during periods of full treatment adherence.\n\nThis objective is preliminary to the use of hair as a tool for detecting treatment non-adherence in patients.\n\nTwo reference antiretroviral molecules will be documented: Emtricitabine and Lamivudine, as they are present, one or the other, in the majority of antiretroviral combination strategies.",[69],"HIV (Human Immunodeficiency Virus)",[71,72,73,74,75],"Antiretroviral treatment","hair","intra-individual variance","HIV","Human immunodeficiency Virus","2026-03-18",{"date":78,"type":79},"2026-03-23","ACTUAL",{"date":81,"type":79},"2025-07-03",{"date":83,"type":64},"2027-06-30",{"name":5,"class":6},1]
