Trial Outcomes & Findings for Study to Estimate the Burden of Herpes Zoster (HZ) and Post-herpetic Neuralgia (PHN) in Italy (NCT NCT01772160)

NCT ID: NCT01772160

Last Updated: 2020-05-22

Results Overview

A case of HZ was defined as new unilateral pain (broadly defined to include allodynia and pruritus) accompanied by unilateral rash and no alternative diagnosis. Age ranges were 50-54, 55-59, 60-64, 65-69, 70-74, 75-79 and greater than or equal to (≥) 80 years. The incidence rate was expressed as the number of HZ cases per (/) 1000 person-years.

Timeframe: Day 0 to 2 years

Population: The analysis was performed on the HZ cases occurring in the total population covered by the participating general practitioners (GPs).

A case of HZ was defined as new unilateral pain (broadly defined to include allodynia and pruritus) accompanied by unilateral rash and no alternative diagnosis. Age ranges were 50-54, 55-59, 60-64, 65-69, 70-74, 75-79 and greater than or equal to (≥) 80 years. The incidence rate was expressed as the number of HZ cases per (/) 1000 person-years.

SECONDARY outcome

Timeframe: At Day 90, 180 and 270 after onset of HZ

Population: The analysis was performed on the HZ cases (with completed questionnaires up to Day 270) occurring in the According-To-Protocol cohort (ATP) which included all evaluable patients (i.e. those who met all eligibility criteria and complied with the study procedures defined in the protocol).

PHN persistence refers to pain occurring or persisting from Day 90 to Day 270 after the rash onset. PHN was assessed via the Zoster Pain Inventory (ZBPI) questionnaire, which includes four pain severity items (worst, least, average, present pain) and seven pain interference items which assess general activity, mood, walking ability, work, relations with others, sleep and enjoyment of life. All of the items are rated on an 11-point Likert scale (0-10). For the severity items, 0 = 'no pain' and 10 = 'pain as bad as you can imagine', whereas for the interference items, 0 = 'does not interfere' and 10 = 'completely interferes'.

EuroQoL-Five Digits (EQ-5D) is a standardised instrument for use as a measure of health outcome and is designed for self-completion by respondents. Its current format is 3-level and 5 dimensional (mobility, self-care, usual activities, pain/discomfort and anxiety/depression). The EQ-5D index was derived from the ratings recorded every 3 months for each of the five individual items (mobility, self-care, usual activities, pain/discomfort and anxiety/depression). The EQ-5D index/scale goes from 0 (worst health state) to 1 (perfect health state).

Population: The analysis was performed on the According-To-Protocol cohort (ATP) which included all evaluable patients (i.e. those who met all eligibility criteria and complied with the study procedures defined in the protocol).

The ZBPI is an assessment tool in the form of a questionnaire completed by the patient that is specifically designed to assess HZ-associated pain and discomfort. The ZBPI includes four pain severity items (worst, least, average, present pain) and seven pain interference items which assess general activity, mood, walking ability, work, relations with others, sleep and enjoyment of life. All of the items are rated on an 11-point Likert scale (0-10). For the severity items, 0 = 'no pain' and 10 = 'pain as bad as you can imagine', whereas for the interference items, 0 = 'does not interfere' and 10 = 'completely interferes'. Note: The Day 90 window included assessments between Day 83 and Day 97 relative to day of rash onset.

PHN persistence refers to pain occurring or persisting between 90-270 days after the rash onset. PHN was assessed via the Zoster Pain Inventory (ZBPI) questionnaire, which includes four pain severity items (worst, least, average, present pain) and seven pain interference items which assess general activity, mood, walking ability, work, relations with others, sleep and enjoyment of life. All of the items are rated on an 11-point Likert scale (0-10). For the severity items, 0 = 'no pain' and 10 = 'pain as bad as you can imagine', whereas for the interference items, 0 = 'does not interfere' and 10 = 'completely interferes'.

EuroQoL-Five Digits (EQ-5D) is a standardised instrument for use as a measure of health outcome and is designed for self-completion by respondents. Its current format is 3-level and 5 dimensional (mobility, self-care, usual activities, pain/discomfort and anxiety/depression). The EQ-5D index was derived from the ratings recorded every 3 months for each of the five individual items (mobility, self-care, usual activities, pain/discomfort and anxiety/depression). The EQ-5D index was 0 (worst health state) to 1 (best health state).
