Trial summary

The purpose of this study is to find out if tonsillectomy reduces the short-term risk of having an objectively confirmed (sequential changes in serum crp and procalcitonin levels) delayed pharyngitis episode among patients suffering from recurrent pharyngitis episodes. Read more about this study

About this study

The purpose of this study is to find out if tonsillectomy reduces the short-term risk of having an objectively confirmed (sequential changes in serum crp and procalcitonin levels) delayed pharyngitis episode among patients suffering from recurrent pharyngitis episodes. Other aims are to find out the effect of tonsillectomy to reduce the number of pharyngitis episodes or symptoms. Still, the possible disadvantages of tonsillectomy and changes in the quality of life after tonsillectomy among these patients are examined.

Read the detailed description

We will have a prospective randomized study. We allocated 87 consecutive patients referred for tonsillectomy randomly in two groups: tonsilectomy group or waiting list(control group). Patients in tonsillectomy group were operated as soon as possible and data on postoperative morbidity was collected. In the control group, patients were placed on our normal waiting list and they were operated on in normal time (about 5-6 months). The data on preoperative morbidity was collected. All the pharyngitis episodes were treated by a study investigator and laboratory tests (crp, procalcitonin) were taken at that time and after three days. In addition, the patients record their symptoms on a diary.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TonsillectomyProcedure or surgery

    Tonsillectomy under general anesthesia as a day surgery using diathermy or blunt dissection. Follow up started from the day of surgery.

  • no interventionOther

    No intervention (controls). Follow up started from the day of randomization.

Study groups in NCT00547391
Study groupRoleWhat they receive
1No interventionpatients on waiting list for a minimum of 5 months. These patients receive no prophylactic intervention for their recurrent pharyngitis episodes.
Receives: Other: no intervention
2Active comparatorTonsillectomy as soon as possible after randomization (within 2-3 weeks).
Receives: Procedure: Tonsillectomy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Absolute percentage difference between groups of patients having pharyngitis with delayed recovery time defined by symptoms and blood sample values (crp, procalcitonin)

    Measured: 5 months follow up

Secondary outcomes (4)
  1. Absolute percentage difference of patients having group A streptococcal pharyngitis.

    Measured: 5 months follow up

  2. Absolute percentage difference of patients having acute pharyngitis episode with and without medical consultation

    Measured: 5 months follow up

  3. Difference in the number and quality (mild, severe) of symptomatic days (fever, sore throat, rhinitis, cough)

    Measured: 5 months follow up

  4. Absolute percentage difference having harmful effects related to tonsillectomy (haemorrhage, soft tissue burns etc.)

    Measured: 5 months follow up

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Tonsillectomy in people with Tonsillitis and Pharyngitis, run by Oulu University Hospital at 1 site in Finland.

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 2 inclusion and 7 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: finished, as of the sponsor's last update on 19 Apr 2012. 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 Finland. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Absolute percentage difference between groups of patients having pharyngitis with delayed recovery time defined by symptoms and blood sample values (crp, procalcitonin) (time frame: 5 months follow up). 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 NCT00547391, which also lists 1 linked publication.

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 19 Apr 2012.
