Observational Study on the Use of Topical Nifedipine 0.3% and Lidocaine 1.5% in Acute Uncomplicated Hemorrhoidal Disease

Обзор

The goal of this observational study is to evaluate the effectiveness of topical nifedipine 0.3% plus lidocaine 1.5% for uncomplicated hemorrhoidal disease. The main question it aims to answer is: Does topical nifedipine 0.3% plus lidocaine 1.5% lower symptoms in patients with uncomplicated acute hemorrhoidal disease? Participants already taking nifedipine 0.3% plus lidocaine 1.5% as part of their regular medical care for hemorrhoidal disease will undergo four visits over a 30-day period, including two telephone contacts and two in-person visits.

Подробное описание

Prospective, observational, single-center study involving the administration of topical nifedipine 0.3% plus lidocaine 1.5%, rectally and perianally twice daily for at least 21 days, in patients with uncomplicated hemorrhoidal disease.

The Primary Objective is to evaluate the real-world effectiveness of topical nifedipine 0.3% + lidocaine 1.5% in acute, uncomplicated hemorrhoidal disease, with particular focus on symptom resolution, assessed through the analysis of changes in the HDSS (Hemorrhoidal Disease Symptom Score) questionnaire. The Secondary Objectives include the assessment of topical combinations effect on reduction of hemorrhoidal prolapse (down-staging), its impact on patients' quality of life and its role in preventing hemorrhoidal thrombosis.

Eligible patients-those who meet inclusion/exclusion criteria, sign informed consent, and receive a clinically indicated therapeutic protocol within 5 days of baseline evaluation (dietary recommendations, hydration, and topical therapy)-will undergo 4 assessments over approximately 30 days:

T0: Baseline visit within 5 days of starting nifedipine 0.3% + lidocaine 1.5% T1: Telephone contact at day 10 T2: In-person visit at day 21 T3: Telephone contact at day 30

The study includes an enrollment period of 10 months, an observation period of \~30 days and total duration of \~12 months

Data will be collected at the study center and entered by the investigator or designated personnel into a web-based electronic database (e-CRF), structured according to the study flow-chart.

The study plans to enroll 80 patients. This number is justified by the expected change in HDSS score between baseline (T-1) and T2 (day 21). Assuming a standard deviation of \~5 points, a sample of 70 patients ensures a precision of 1.2 points for 95% confidence intervals. To account for a 10% drop-out rate, the final sample size is set at 80 patients.

Continuous variables will be described using mean ± SD, quartiles (25%, 50%, 75%), and min/max.

Categorical variables using absolute frequencies and percentages. Statistical analysis will be performed using SAS 9.4.

Первичные конечные точки

  • Change in HDSS (hemorrhoidal disease symptom score) questionnaire, analyzed using paired t-test or Wilcoxon signed-rank test according to data distribution. The total HDSS ranges from 0 to 20, with higher scores indicating greater symptom severity. [Срок оценки: From enrollment to the 30-day follow-up]
