Brief Summary

Nocturnal hypertension (i.e. blood pressure values \>120/70 or 10% higher than diurnal values, as measured by ambulatory blood pressure monitoring, ABPM) is particularly frequent in renal transplant recipients (RTR), despite the use of antihypertensive drugs. Since RTR are also affected by several sleep disorders (like insomnia, restless legs syndrome, sleep apnoea) that frankly impair their quality of sleep (SQ), the aim of the present study is to ascertain whether a relationship exists between nocturnal hypertension and SQ. In fact, both nocturnal hypertension and sleep disorders may favour the onset or the progression of cardiovascular diseases, the first cause of death in RTR.

Outcome Measures

Primary Outcomes (1)

  • Prevalence of "poor sleepers", as assessed by Pittsburgh Questionnaire, among renal transplant recipients with elevated blood pressure, measured by ambulatory continuous monitoring.

    Sleep quality will be evaluated by the Pittsburgh Questionnaire, which allows to investigate on 7 different components of sleep, determining a score ranging between 0 and 19: a score\>5 defines a "poor sleeper". Through bivariate and multivariate analysis, the study will evaluate which relationship exists between nocturnal hypertension ands sleep quality.

    Given the cross-sectional nature of the study, there is a single determination of sleep quality in each patient, carried out after completion of 24-hour ABPM, during a scheduled follow-up visit.

Interventions

All the patients will be administered the Pittsburgh Questionnaire after completion of ABPM.
