About this study

Official title: Observational Study on the Effect of Anticholinergic on the Autonomic System in Women With OAB

The aim of the study is to evaluate changes in autonomic nervous system following treatment with anticholinergic medication for OAB symptoms.

Heart variability as a measure of the functioning of the autonomic nervous system will be recorded before and three months following treatment with solifenacin succinate 10 mg daily.

Read the detailed description

30 women with clinical diagnosis of overactive bladder will be recruited for the study. An ECG strip for fifteen minutes at rest will be recorded through a 12-bit analog/digital data acquisition card (National Instruments, Austin TX) with a sampling frequency of 200 Hz and stored in a computer for offline studies. The digitized ECG signals will than processed and analyzed via dedicated robust software to detect the R wave peaks. The R point of each QRS complex was defined and the interval between two consecutive R points (the R-R interval) was computed. All R-R intervals will be visually inspected and manually edited if necessary to exclude background noise and artifacts. The edited segments accounts for less than 1% in each patient. A "clean" 2-5-min segment (preferably unedited) will be used for the analyses. An autoregressive model with the order of 16 was will be used to estimate the power spectrum densities of HRV. The power spectra are quantified by measuring the area under the following frequency bands: low-frequency (LF) (0.04-0.15 Hz) known to represents sympathetic activity, and high-frequency (HF) (0.15-0.4 Hz) which represents parasympathetic activity.

Questions about this trial

What is this clinical trial studying?

An observational study of Overactive Bladder, run by Rambam Health Care Campus at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 4 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Dalia Kesner, MD (DALIAKE@clalit.org.il), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in heart variability following treatment with Solifenacin succinate 10 mg (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01409512, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2011.
