About this study
Official title: Possible Relationship Between Apoptosis and Endoplasmic Reticulum Stress in the Etiopathogenesis of Chronic Tonsillitis and Tonsillar Hypertrophy
Tonsillar tissue is a significant organ for the performing of immune systems in children. The Endoplasmic Reticulum (ER), is an organelle needed for the care of a stable function of the cells. The purpose of the study was to explore the correlation among ER stress and tonsillar tissue disorders and to explain the structure of diseases related to the immune system.
Read the detailed description
A prospective study was conducted on 46 children aged who underwent tonsillectomy for chronic tonsillitis or tonsil hypertrophy. Tonsil tissues were evaluated in terms of ER stress markers and apoptosis markers by Real-time PCR and Western blot methods.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Tonsillectomy surgeryProcedure or surgery
The tonsillectomy procedure was performed under general anesthesia using the classical dissection method. Extracted tonsil tissue samples were sent to the medical genetics department in tubes to investigate the ER stress and apoptosis.
| Study group | Role | What they receive |
|---|---|---|
| Chronic tonsillitis | Patients with tonsil sizes grade 1 and 2, and tonsillectomy indications included frequently recurrent tonsillary infection, sore throat, and malodorous mouth problems were accepted as the chronic tonsillitis group. Receives: Procedure: Tonsillectomy surgery | |
| Tonsillar hypertrophy | Patients with tonsil size grades 3 and 4 and tonsillectomy indications included obstructive symptoms such as snoring, open mouth breathing, difficulty in breathing, and swallowing problems were accepted as the tonsillar hypertrophy group. Receives: Procedure: Tonsillectomy surgery |
What is being measured
The primary outcome is the main question the study is designed to answer.
Relationship of Endoplasmic Reticulum stress and apoptosis with chronic tonsillitis and tonsillar hypertrophy
Our primary outcome was to evaluate providing that Endoplasmic Reticulum stress and apoptosis reaction performing in chronic tonsillitis and tonsillar hypertropy, which is related with the immune system of children. GRP78, CHOP, ATF6, ATF4 proteins will be investigated in tonsillar tissues to evaluate ER stress index, and bax, bcl2 proteins will be investigated to evaluate apoptosis.
Measured: 2018-2020

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?
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?
Relationship of Endoplasmic Reticulum stress and apoptosis with chronic tonsillitis and tonsillar hypertrophy (time frame: 2018-2020). 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 NCT04653376, which also lists 3 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 Dec 2020; AzTrials last refreshed its copy on 7 Nov 2026.
