Interpretation of Tonsillectomy Outcome Inventory-14 scores: a prospective matched cohort study.

PURPOSE: Knowledge of disease-specific instruments enables the evaluation of health- related quality-of-life (QoL) change associated with chronic and recurrent tonsillitis in adults. The main objective was to explore the interpretation of scores according to the throat-related QoL instrument, Tonsillectomy Outcome Inventory-14 (TOI-14), by determining the typical scores in healthy subjects and patients and define the minimum important change (MIC). METHODS: We performed a prospective matched cohort study in a secondary care area of Oulu University Hospital. The surgical cohort consisted of 42 patients referred to tonsillectomy due to recurrent or chronic tonsillitis. The control cohort consisted of 42 age- and sex-matched healthy controls obtained from the escorts of patients in the same hospital. We translated and validated the Finnish TOI-14 instrument and collected TOI-14 scores at entry and at 6 months and compared results to the anchor question. RESULTS: At entry, the mean TOI-14 scores were significantly higher in the surgical cohort than in the control cohort [mean (95% confidence interval)] 33.0 (27.0-39.1) vs. 5.0 (3.6-6.4), respectively. At 6 months follow-up, the mean TOI-14 scores had improved markedly after tonsillectomy to the level of the control cohort. In the healthy population, the score was in most cases under 15.0 points. In patients, a score of about 20.0 indicated mild symptoms, 30.0 moderate symptoms and 40.0 or higher intense symptoms. The MIC value was 10.0 points. CONCLUSIONS: These results enable the more accurate interpretation of the scores of the only disease-specific QoL instrument for adult throat-related diseases.

Endoscopic sinus surgery (ESS) to change quality of life for adults with recurrent rhinosinusitis: study protocol for a randomized controlled trial.

BACKGROUND: Endoscopic sinus surgery (ESS) has been used for decades to treat recurrent acute rhinosinusitis episodes (RARS) in adults. RARS results in infectious symptoms, antibiotic courses, sick leaves, and impaired quality of life. Theoretically, the ESS procedure, through improving the drainage of the paranasal sinuses, decreases the symptoms and enhances the quality of life of the RARS patients. Whether this is true has not been reported in a randomized trial yet. METHODS: We conduct a single-center, non-blinded, randomized, 6-month, parallel group superiority clinical study including 80 adult participants referred to surgical treatment for RARS. The participants will either have ESS or conservative medical treatment (control group). The primary outcome will be the difference between the mean disease-specific Sinonasal Outcome Test 22 (quality of life questionnaire) change scores (from baseline to 6 months) of ESS and control group. DISCUSSION: This study will add significant new information to the effect and harms of ESS procedure in the treatment of adults with RARS. TRIAL REGISTRATION: ClinicalTrials.gov NCT04241016 .

Total or partial tonsillar resection (tonsillectomy or tonsillotomy) to change the quality of life for adults with recurrent or chronic tonsillitis: study protocol for a randomised controlled trial.

BACKGROUND: Tonsillar surgery has been used for decades to treat recurrent and chronic tonsillitis in adults. Recurrent and chronic tonsillitis result in disturbing symptoms, treatment costs, sick leave, and impaired quality of life (QoL). Theoretically, removing all or part of the altered pathological palatal lymphoid tissue alleviates the symptoms and enhances the QoL. Whether this is true with total or partial tonsillar resection (tonsillectomy (TE) and tonsillotomy (TT), respectively) has not been reported in a randomised trial yet. METHODS: We conduct a multicentre, partly blinded, randomised, 6-month, parallel-group clinical study including 285 adult participants referred to surgical treatment for chronic or recurrent tonsillitis. The participants will either have TE, TT or watchful waiting (WW). The primary outcome will be the difference between the mean disease-specific Tonsillectomy Outcome Inventory-14 (QoL questionnaire) scores at 6 months. Comparison is made firstly between the combined TE+TT and WW groups (superiority analysis), and secondly between the TE and TT groups (non-inferiority analysis). DISCUSSION: This study will add significant new information to the effects and harms of TE and TT procedures in the treatment of adults with chronic or recurrent tonsillitis. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04657549.

Tonsillar granuloma associated with hypogammaglobulinemia.

BACKGROUND: Rare tonsillar granulomas may be caused for example by infections, malignancies or sarcoidosis. Granulomas also occur in inborn errors of immunity (IEI) such as common variable immunodeficiency (CVID) with B cell maturation defects and hypogammaglobulinemia. CVID shares various features with sarcoidosis and drug-induced secondary hypogammaglobulinemia; careful consideration of differential diagnosis between these conditions is warranted. CASE PRESENTATION: A 29-year-old female with epilepsy developed dysphagia, dyspnea and impaired exercise tolerance. Obstruction caused by swollen lingual tonsil and edema in the epiglottis and arytenoid mucosa were found. Lingual tonsil and epiglottis biopsies displayed non-necrotizing granulomas. There was no evidence of viral, bacterial, mycobacterial or fungal infections. Chest X-ray, computerized tomography of chest and ultrasound of neck and abdomen remained unremarkable. Positron emission tomography/computed tomography (PET/CT) showed laryngeal enhancement. Empiric antimicrobials combined with prednisolone were insufficient to control her disease. In immunological evaluation, the patient had normal counts of B and T cells. Proportions of CD27+ memory B cells (30.3%) and IgD-IgM-CD27+ switched memory B cells (7.2%; normal range 6.5-29.2%) were normal. Percentage of activated CD21low B cells was high (6.6%; normal range 0.6-3.5%). IgG (3.5 g/L; normal range 6.77-15.0 g/l) and all IgG subclass concentrations were low. Anti-polysaccharide responses were impaired, with 3/10 serotypes reaching a level of 0.35 µg/ml after immunization with Pneumovax®. The findings were consistent with hypogammaglobulinemia resembling CVID, possibly secondary to antiepileptic medication. Her dyspnea and dysphagia responded favorably to subcutaneous IgG and rituximab. CONCLUSIONS: Tonsillar granulomas can be the presenting and only clinical feature of B cell deficiency, highlighting the diversity of symptoms and findings in primary or secondary immunodeficiencies.
