Brief Summary

The problem of adherence to long-term therapies has been known for years and occurs substantially in all countries, although with greater severity in developing countries. The investigators designed a prospective open study in which 200 patients followed for hypertension at the centers of the Italian Society of Hypertension (SIIA) adhering to the project will be evaluated on the basis of their clinical characteristics, the presence of comorbidities and the therapeutic scheme in place and will be subjected to hair sampling for the analysis of drugs of interest and their possible metabolites in this matrix. The use of the prescribed drugs is recorded along with the relevant clinical parameters and preliminarily evaluated by application of a questionnaire. At the first visit, patients who have been prescribed continuously in the 3 months preceding the study the same active ingredients will be invited to participate in the study, which involves a hair sampling. They will then be prescribed the same active ingredients according to the same scheme if the blood pressure values are within the recommended limits. When more than one antihypertensive drug is present in the therapeutic scheme, they will be prescribed in a single pill, as recommended. For patients with uncontrolled blood pressure, the therapeutic scheme will be modified with the inclusion of other active ingredients and using drug combinations when possible. Patients treated with statins will continue the treatment according to clinical indication using associations with antihypertensive drugs. Patients will be examined and re-tested 3-4 months after the first visit. The use of prescribed medications will be recorded along with clinical parameters of interest and preliminarily evaluated by application of questionnaires. At each of the two visits, the investigating physician will measure blood pressure using a semi-automatic device The 24-hour blood pressure monitoring will be used. Hair extraction ad UHPLC-QQQ/MS analysis will be performed. Concentrations of active ingredient and any metabolites in the keratin matrix are expressed in ng or fractions of ng/mg.

Outcome Measures

Primary Outcomes (2)

  • Determination of the concentration of antihypertensive drugs in hair samples collected at the first and second visits

    Determination of drug concentration is used for the classification of patients as adherent or non-adherent to therapy or part of therapy based on the presence of quantifiable drugs in different segments of the hair sample representative of the time interval covered by the study

    3 months

  • Determination of the concentration of statins prescribed to patient in hair samples collected at the first and second visits

    In patients who have had a prescription of statins in addition to antihypertensive drugs, their quantification in hair samples will be used to define the adherence to therapy.

    3 months

Secondary Outcomes (4)

  • Comparison the results of hair analysis performed at the first and second visits.

    3 months

  • Comparison of adherence to therapy in the presence of change in therapy

    3 months

  • Analysis of the relationship between adherence to therapy and factors associated with the patient.

    3 months

  • Assessment of the feasibility of hair analysis

    3 months

Interventions

Sampling MethodProbability Sample
Study Population

Adult patients (n=200) followed for essential hypertension at the SIIA centres will be evaluated on the basis of their clinical characteristics, the presence of comorbidities and the therapeutic scheme in place and will be subjected to hair sampling for the analysis of drugs of interest and their possible metabolites in this matrix. The use of the prescribed drugs will be recorded along with the relevant clinical parameters and preliminarily evaluated by application of a questionnaire.

You may qualify if:

  • All patients older than 18 years of both sexes with a diagnosis of hypertension undergoing treatment for at least 3 months with antihypertensive drugs and also statins.
  • Diagnosis of secondary forms of hypertension excluded.
  • Subjects who express their willingness to participate in the study by signing the consent form having understood the content of the written and verbal information provided about the purpose and mode of execution of the study.

You may not qualify if:

  • Subjects unable to express voluntary adherence to the study.
  • Renal insufficiency with estimated glomerular filtrate less than 50 mL/minute-
  • Heart failure with functional class equal to or greater than II.
  • Chronic inflammatory disease.
  • Neoplastic disease.
  • Any chronic diseases requiring continuous treatment with drugs known to interact pharmacokinetically with the antihypertensive drugs being monitored.
