Importance of biomarkers in streptococcal acute tonsillitis & peritonsillar abscess.

Background & objectives Acute tonsillitis is a disease that can often be cured with medical treatment. However, complications may occur during this disease process. One of these complications is peritonsillar abscess. In recent years, biomarkers have been frequently used in the diagnosis of diseases. The aim of the study was to reveal whether peritonsillar abscess develops after acute tonsillitis, and acute tonsillitis can be differentiated using biomarkers and which biomarker has higher predictive value for this differentiation. Methods The control group consisted of individuals who were operated for septoplasty in the otolaryngology clinic, and the acute tonsillitis group consisted of individuals diagnosed with acute tonsillitis in the same clinic. Both groups were statistically compared in terms of mean platelet volume (MPV), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic immune inflammation index (SII), infection discrimination index (IDI), plateletcrit (PCT) and lymphocyte to monocyte ratio (LMR) biomarkers. Statistically, significant biomarker values were compared between the subgroups in the tonsillitis group of those who had only acute tonsillitis and those who had peritonsillar abscess due to acute tonsillitis. Receiver operating characteristics (ROC) curve analysis was performed on biomarkers for their ability to predict the presence of peritonsillar abscess. Results When the individuals who had only acute tonsillitis and those who had acute tonsillitis with peritonsillar abscess were compared in terms of biomarkers, there was a statistically significant difference between the mean MPV, SII and PCT (P=0.010, 0.021, 0.023, respectively). ROC analysis was performed to calculate the sensitivity and specificity of MPV, PCT and SII for the diagnosis of acute tonsillitis with peritonsillar abscess (sensitivity-specificity for MPV 51.9-72.7%, for SII 94.2-32.7%, for PCT 71.2-50.9%, respectively). Interpretation & conclusions MPV, SII and PCT biomarkers may be useful to help clinicians predict peritonsillar abscess due to acute tonsillitis.

Impact of adenotonsillectomy on the evolution of inflammatory markers.

BACKGROUND: Tonsils are first-line host defence organs against pathogenic agents and participate in local and systemic immunity. Persistent increases in systemic inflammatory responses may contribute to associated morbidity. The aim of this study was to verify the short- and long-term impact of adenotonsillectomy on the evolution of inflammatory markers in 3- to 9-year-old children. METHODS: A prospective and longitudinal study was conducted over 1 year in 29 children who underwent tonsillectomy due to either chronic tonsillitis or adenotonsillar hypertrophy. Measurements of high-sensitivity C-reactive protein (hs-CRP) levels were taken. Levels of Th1-type cytokines [interleukin-1, interferon-γ, and tumor necrosis factor-α (TNF-α)] and anti-inflammatory Th2-type cytokines [interleukin-4, -5, -6, -10 and -13] were measured. Levels of transforming growth factor-beta (TGF-ß) and intercellular adhesion molecule-1 (ICAM-1) were also determined. The results were compared to those of 29 control children. RESULTS: At baseline, children with surgery indications presented with higher levels of hs-CRP, interleukin-1 and -10, interferon-γ, TNF-α and ICAM-1, whereas values of interleukin-4 were significantly lower than in control children. Children with severe tonsillar obstruction had higher values of interleukin-1, -4, and -5 and lower values of interleukin-10 compared with children with recurrent tonsillitis. One year after surgery, the levels except IL-4 did not show a significant difference from those obtained in the control group. The levels of hs-CRP and TNF-α decreased significantly in the first month. CONCLUSION: Children with chronic tonsillitis and/or adenotonsillar hypertrophy have significantly elevated levels of proinflammatory cytokines. Adenotonsillectomy restores the normal values of these parameters 1 year after surgery.

Preoperative plasma fibrinogen as a predictive factor for post-tonsillectomy haemorrhage.

OBJECTIVES: To assess whether preoperative plasma fibrinogen is able to predict severe post-tonsillectomy haemorrhage. STUDY DESIGN: Retrospective chart review. METHODS: We included 456 patients who underwent tonsillectomy between 2008 and 2013. Preoperative plasma fibrinogen levels (PFL) were assessed in patients who developed severe bleeding requiring surgical revision under general anesthesia compared to those with uneventful postoperative courses. RESULTS: 414 (90.8%) had no severe post-tonsillectomy haemorrhage. In contrast, 42 (9.2%) patients needed surgical hemostasis. PFL were significantly higher (P = .023) in patients with a severe bleeding. Univariate Cox-regression analysis revealed that elevated preoperative fibrinogen represents a significant worse (P = .003; HR 2.66; 95% CI 1.38-5.10) prognostic factor for postoperative bleeding. Even at multivariable analysis, increased PFLs were a significantly worse prognostic factor for post-tonsillectomy haemorrhage (P = .016; HR 15.4; 95% CI 0.01-0.6). High preoperative PFL was associated with significantly higher risk for post-tonsillectomy haemorrhage within the first 31 days after surgery (65% vs 90%; P = .002). Moreover, accurate negative predictive value (NPV) of 95.1% pointed out that PFL could be used as a reliable preoperative screening marker. CONCLUSIONS: Elevated PFL represents an independent worse prognostic factor for severe bleeding after tonsillectomy and could be helpful to identify patients at higher risk for PTH.

Association between Ca/Mg/P status and suppurative tonsillitis in children.

Suppurative tonsillitis (ST) is a common respiratory disease in children. This study aims to investigate the association between calcium (Ca)/magnesium (Mg)/phosphorus (P) and the risk of onset of suppuration in tonsillitis in children. Seventy children with ST and 61 age- and sex-matched children with non-ST were enrolled in this study. The association between Ca/Mg/P and suppuration risk in tonsillitis was investigated. The relationship between Ca/Mg/P and the potential risk factors for ST were also studied. White blood cell (WBC), platelet (PLT), c-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels were significantly higher in the ST group than those in the non-ST group (p less than 0.05). Mg and P levels were significantly lower in the ST group than those in the non-ST group (p less than 0.05). There was no obvious difference in Ca level between the ST group and the non-ST group (p=0.762). A significantly negative association between P and PCT was noted (r=-0.236, p=0.035). The results indicated that Mg/P disorder may be associated with the susceptibility to suppuration in children with tonsillitis, inflammatory indexes may reflect this risk.

Amoxicillin and clavulanate potassium in treating children with suppurative tonsillitis.

To evaluate clinical effects of amoxicillin and clavulanate potassium in the treatment of children with suppurative tonsillitis, 146 children with suppurative tonsillitis were randomly divided into a ceftezole sodium group and an amoxicillin and clavulanate potassium group. The two groups were given anti-infection treatment using different drugs. Symptomatic treatment was carried out once symptoms such as fever appeared. Five to seven days were taken as one treatment course. Blood routine examination and the detection of C-reactive protein (CRP) were performed three days after treatment. Indexes such as the time to the relief of symptoms, the count of white blood cells, the proportion of neutrophil and CRP levels and the incidence of adverse reactions were compared between groups to evaluate the curative effect. The overall response rate of the amoxicillin and clavulanate potassium group was 94.52%, while that of the ceftezole sodium group was 78.08%; the difference was statistically significant (P<0.05). The improvement of white blood cells and CRP levels of the amoxicillin and clavulanate potassium group was more obvious than that of the ceftezole sodium group (P<0.05). The difference of the time to the improvement of symptoms between the two groups had statistical significance; the amoxicillin and clavulanate potassium group was superior to the ceftezole sodium group (P<0.05). No severe drug-related adverse reactions were observed. Amoxicillin and clavulanate potassium dispersible tablet is effective in treating children with suppurative tonsillitis as it can rapidly relieve the clinical symptoms without increasing incidence of adverse reactions.

Evaluation of iron and zinc levels in recurrent tonsillitis and tonsillar hypertrophy.

OBJECTIVES: The aim of this study is to look into the roles of iron and zinc metals in etiopathogenesis of recurrent tonsillitis and tonsillar hypertrophy by evaluating the levels of iron and zinc elements in the palatine tonsillar tissue. METHODS: In total, 40 patients who underwent a tonsillectomy to treat recurrent tonsillitis and tonsillar hypertrophy were included in the study. Patients were classified into two groups, recurrent tonsillitis and tonsillar hypertrophy, determined by the results of clinical and histopathological examination. The levels of iron and zinc elements were determined for each tonsillar tissue sample. RESULTS: There was a significant difference in the iron and zinc concentrations (p<0.001) between the tonsillar hypertrophy and recurrent tonsillitis groups. The levels of iron and zinc were significantly lower in the recurrent tonsillitis group. CONCLUSIONS: This study suggests that low tissue concentrations of iron and zinc may lead to recurrent tonsillitis.

USE OF NEUTROPHILS TO LYMPHOCYTES RATIO AS AN INFLAMMATION MARKER IN PATIENTS WITH CHRONIC TONSILLITIS.

The aim of this study was to assess the neutrophil to lymphocyte ratio (NLR) as an inflammation marker in patients with chronic tonsillitis and to compare the NLR values to other inflammation markers, such as antistreptolysin-O (ASO), C-Reactive Protein (CRP) and erythrocyte sedimentation rate (ESR). Thirty patients aged between 4 and 15 y.o. who had undergone surgery for chronic tonsillitis were included in this retrospective study. Blood samples including haemogram, ASO, CRP and ESR were taken from the patients the day before and one month after the surgery and were analysed retrospectively. Preoperative ASO values were 170±75.5 U, CRP values were 7.6±5 mg/L, ESR values were 15.7±10 mm/H and NLR values were 0.9±0.2. Postoperative ASO values were 140.9±58.5 U, CRP values were 6.8±3.4 mg/L, ESR values were 12.5±5.4 mm/H and NLR values were 1.2±0.4. Statistically significant decreases were observed in the white blood cell count (WBC), lymphocytes, ASO and ESR results, with increase in NLR values after the surgery (p<0.05). The neutrophil and CRP values after the surgery have shown statistically insignificant decrease (p>0.05). The NLR values were compared with the ASO, CRP and ESR values, which were used as inflammation markers. Negative correlation was found between decrease in ASO and ESR and increase in the NLR values after the surgery.

Serum 25-hydroxyvitamin D levels in children with recurrent tonsillitis living in Milan.

Involvement of 25-hydroxyvitamin D in the etiopathogenesis of tonsillar disease in children is still debated; this study assesses possible differences in serum 25-hydroxyvitamin D levels between 309 Caucasian children (58.1% males; mean age 55.7 ± 31.0 months) living in Milan with a history of recurrent tonsillitis (RT) and healthy controls. Mean serum 25(OH)D levels were significantly reduced in the children with a history of RT (22.0 ± 8.7 ng/mL vs 24.6 ± 7.8 ng/mL; p=0.03), and the proportion of children with insufficient or deficient serum 25(OH)D levels was higher in the RT group (81.5% and 6.5% respectively) than in the control group (75.1% and 3.5%) (not significant). The multivariable model created to test the independent association between serum 25(OH)D levels and a history of RT after adjusting for age and season showed that the association was not significant. Our study failed to find any significant reduction in serum 25(OH)D levels after adjustment for age and season in a case series of children with RT in comparison with healthy controls, which suggests that vitamin D does not play a relevant role in the etiology of pediatric tonsillar infections.

Blood parameters as indicators of upper airway obstruction in children with adenoid or adenotonsillar hypertrophy.

UNLABELLED: Adenotonsillar hypertrophy (ATH) is the most common cause of obstructive sleep apnea in children. This study aimed to evaluate the blood parameters of children with ATH who underwent surgery. METHODS: The study included a review of the medical records of 130 children who underwent adenoidectomy or adenotonsillectomy with a diagnosis of adenoid hypertrophy and/or chronic tonsillitis. Patients were classified into 3 groups: group 1 (n=69) underwent adenoidectomy, group 2 (n=61) underwent adenotonsillectomy, and group 3 consisted of 82 healthy children. White blood cell count, platelet count, hemoglobin levels, mean platelet volume, and platelet distribution width values were the primary outcome measures. RESULTS: Mean platelet volume, platelet distribution width and hemoglobin values decreased in the groups that underwent surgery. Whereas the decrease in group 1 was insignificant, it was significant in group 2. White blood cell count values increased in both group 1 (adenoidectomy) and group 2 (adenotonsillectomy), but the increase in group 2 was significant. No significant difference in platelet count was detected before versus after the operation. CONCLUSIONS: Upper airway obstruction caused by ATH remarkably changes the blood parameters related to chronic hypoxia. Significant improvement can be achieved after adenotonsillectomy rather than adenoidectomy alone.

Are procalcitonin or other infection markers useful in the detection of group A streptococcal acute tonsillitis?

BACKGROUND: The Centor criteria and the streptococcal rapid antigen detection test (RADT) are commonly used to differentiate sore throat patients with group A streptococci (GAS) from patients with other pathogens. We aimed to investigate if procalcitonin (PCT), C-reactive protein (CRP), white blood cell count (WBC), and absolute neutrophil count (ANC) could increase the diagnostic accuracy when added to the Centor score and RADT, or be used instead of the RADT, in the differential diagnosis. METHODS: A 6-month prospective study was carried out in a Danish general practice with 8 physicians. One hundred acute tonsillitis patients aged 15 to 40 y were included. RESULTS: The prevalence of GAS was 26%. The sensitivity (90%) and specificity (97%) of the RADT were high. Mean values of CRP, WBC, and ANC were significantly higher in patients with GAS compared to non-GAS patients (p < 0.001). However, the sensitivities (66-90%) and specificities (45-75%) were low. No difference in PCT levels was found (p = 0.334). CRP was the most reliable infection marker (sensitivity 90% and specificity 45%) for GAS aetiology. CONCLUSIONS: The sensitivity, specificity, and area under the curve of the RADT were higher than those of the 4 measured infection markers in the differentiation between GAS and non-GAS acute tonsillitis patients. The infection markers did not increase the diagnostic accuracy when added to the Centor score and RADT. When RADT is not available, measurement of CRP or ANC may increase the diagnostic accuracy in the detection of GAS-positive patients.

Preoperative serum pattern analysis to predict the outcome of tonsillectomy in adults with chronic tonsillitis.

The method of classification and tree analysis (CART) was used to predict the outcome of tonsillectomy for chronic tonsillitis (CHT) analyzing patterns of serological markers. In a prospective case study of 24 adult patients with CHT in comparison to 24 patients with acute peritonsillar abscess (PTA) blood samples were assessed 1 day before (T-1) and 3 days after tonsillectomy. Outcome 6 months later (T180) was documented using the Glasgow Benefit Inventory (GBI) and the Specific Benefits from Tonsillectomy Inventory (SBTI). In comparison to PTA, patients with CHT were at best classified by C-reactive protein with a cut-off value of <16.735 mg/dl. For CHT, immunoglobulin E ≤ 144.65 kU/l and the combination of monocytes ≤ 0.565 Gpt/l plus leucocytes >5.855 Gpt/l at T-1 were the best classificators for higher SBTI overall score and symptom score symptom score, respectively, at T180. A higher benefit subscore at T180 was associated to γ-globulin >15.85 % plus α2-globulin >8.950% at T-1. The best classificator for better GBI overall score at T180 was an ASL titer >169.0 IU/ml or the combination of an ASL titer ≤ 169.0 IU/ml with lymphocytes ≤ 2.195 Gpt/l. Lymphocytes ≤ 2.195 Gpt/l were associated with higher GBI general subscore. Leukocytes ≤ 6.780 Gpt/l were related to higher GBI social support subscore. The combination of immunoglobulin A >1.360 g/l with procalcitonin level >0.058 ng/ml was the best combination to classify for higher physical health score. Instead of looking on isolated serologic markers, CART of multiple parameters seems to be more effective to predict the outcome of tonsillectomy for CHT.

Impact of Low-Temperature Plasma Radiofrequency Tonsillectomy on Pain, Inflammatory Markers, and Sleep Quality in Adults with Chronic Tonsillitis.

AIM: Chronic tonsillitis (CT) is a very common ear, nose, and throat disease worldwide, and in severe cases it can cause sleep apnea hypoventilation syndrome, which can affect the patient's health and can even be life-threatening. Low-temperature plasma radiofrequency tonsillectomy is one of the commonly used methods for treating CT with remarkable results, but more detailed reports are lacking. In this study, we aimed to explore the impact of low-temperature plasma radiofrequency tonsillectomy on pain, inflammatory markers, and sleep quality in adult CT patients for clinical reference. METHODS: A retrospective study was performed on adult patients diagnosed with CT at our hospital between June 2019 and October 2023. Patients were categorized into a control group receiving traditional tonsillectomy and a treatment group undergoing low-temperature plasma radiofrequency tonsillectomy. The groups were compared in terms of baseline characteristics, surgical parameters, visual analogue scale (VAS) scores, 36-item short form (SF-36) health survey questionnaire scores, inflammatory markers, and Pittsburgh Sleep Quality Index (PSQI) scores. Group differences in postoperative complications were also analyzed. RESULTS: There were 160 patients, 80 in the treatment group (50 males and 30 females, mean age 28.90 ± 2.46 years) and 80 in the control group (46 males, 34 females, mean age 28.89 ± 2.01 years). Differences between the two groups in terms of age, sex, duration of disease, smoking history, body mass index, and other baseline characteristics were not statistically significant (p > 0.05). Operation time, intraoperative bleeding, return to normal diet, and pseudomembrane detachment time in the treatment group were all significantly lower than in the control group (p < 0.05). There were no significant differences in VAS or SF-36 scores before treatment (p > 0.05). Post-treatment, both groups had lower VAS scores and higher SF-36 scores in the treatment group compared to the control group (p < 0.05). There were no significant differences in levels of inflammatory markers before treatment (p > 0.05). Both groups showed increased levels of inflammatory markers post-treatment, but the treatment group had lower post-treatment levels of Interleukin-6 (IL-6) and hypersensitive-C reactive protein (hs-CRP) than the control group (p < 0.05). No significant difference was observed between the two groups in PSQI scores before treatment (p > 0.05). Following treatment, both groups had decreased PSQI scores, with lower scores in the treatment group than in the control group (p < 0.05). The complication rate was lower in the treatment group than in the control group, with rates of 8.75% and 23.75%, respectively (p < 0.05). CONCLUSIONS: Low-temperature plasma radiofrequency tonsillectomy for adult CT patients offers advantages such as shorter surgical time, reduced intraoperative bleeding, minimal trauma, and fewer postoperative complications. This procedure significantly alleviates pain, improves quality of life, reduces levels of inflammatory markers, and enhances sleep quality.

Clinical significance and diagnostic usefulness of serologic markers for improvement of outcome of tonsillectomy in adults with chronic tonsillitis.

BACKGROUND: The aim of the present study was to explore serological biomarkers which predict the outcome of tonsillectomy for chronic tonsillitis. METHODS: A case study in a University ENT department of 24 adult patients with chronic tonsillitis (CHT) in comparison to 24 patients with acute peritonsillar abscess (PTA) was performed. Blood samples for clinical routine hematological and serological parameters were assessed prior to surgery (T-1) and five days (T5) after tonsillectomy. Outcome 6 months later (T180) was documented using the Glasgow Benefit Inventory (GBI) and the Specific Benefits from Tonsillectomy Inventory (SBTI). Correlation analyses between CHT and PTA group as well as between the different time points within each group concerning the serological parameters and the outcome parameters were performed. RESULTS: At T-1, patients in the CHT group presented with significantly higher lymphocytes counts (relative and absolute), basophils (relative and absolute) and eosinophils but less white-cells, monocytes, neutrophils (absolute and relative), alpha-1, alpha-2, beta globulins, immunoglobulin and lower C-reactive protein and procalcitonin values than patients in the PTA group (all p < 0.05, respectively). Within each group, different significant changes of the serum parameters (often in opposite direction) were observed between T-1 and T5. SBTI scores at T-1 were significantly lower in the CHT group. In contrast, most GBI scores at T180 were significantly higher in the CHT group. Between T-1 and T180 the SBTI scores improved in three quarters of the CHT patients but only in three fifths of the PTA patients. Higher eosinophil counts and immunoglobulin E levels at T-1 predicted higher GBI scores at T180 in the CHT group. CONCLUSIONS: This pilot study showed a specific serological pattern for patients with chronic tonsillitis with a specific pattern of changes after tonsillectomy. But there is no established role for biomarkers currently used in clinical practice to predict the outcome of tonsillectomy for chronic tonsillitis.

[State of the immune system in children with tonsillitis-induced lesions of the cardiovascular system].

Purpose of work was study the state of the immune system in children with non-inflammatory tonzillogenic lesions of the cardiovascular system. The article describes the main features of the immune status of children 6-18 years with chronic tonsillitis with lesions of the cardiovascular system. We analyzed the content of serum lymphocytes, T-lymphocytes, T-helper cells, T-suppressor, null cells, B-cells, the concentration of immunoglobulin (Ig) A, G, M, immunoregulatory index. Found that children with chronic tonsillitis and tonzillogenic heart disease immune status changes were more significant in contrast to children with chronic tonsillitis without cardiac complications and manifested significant increase in T-suppressor cells, Ig M and decreased T-lymphocytes (P < 0.01).

[Estimation of clinical-pathogenetic efficiency of reamberin and cycloferon application in patients with the severe form of acute tonsillitis].

Efficiency of reamberin and cycloferon application combination at the patients with the heavy form of acute tonsillitis was investigated. It is set that cycloferon and reamberin application in the complex of treatment of the patients with this pathology is instrumental in normalization of the general state and feel of patients, liquidation of both commontoxic syndrome and local inflammatory displays in pharynx, and also normalization of the studied biochemical and immunological indexes. Application of cycloferon and reamberin provides the decline of "average molecules" and malon dialdehyde level to norm, that testifies about liquidation endogenous "metabolic" intoxication syndrome, and also instrumental in normalization of phagocytes activity of monocytes indexes, that describe normalize operating of the indicated preparation on the macrophage phagocytes system.

[Influence of сycloferon on the сytokine blood profile and production of proinflammatory сytokines in the cultures of mononucleares of peripheral blood of the patients with chronic tonsillitis].

The 88 patients with chronic tonsillitis (CT) was investigated. The 46 patients (basic group) got the modern immunoactive preparation cycloferon and 42 patients (comparison group) - only the generally accepted therapy. During immunological researches on a background clinical manifestation of СT the increase proinflammatory cytokines (CK) (TNFα, IL-1Β) in the serum, and also increase the level of spontaneous products of these CK in the cultures mononucleares of periferal blood was detected. At general accepted treatment took place increase level proinflammatory CK at serum on background decline stimulated product of CK at mononucleares cultures. Aрplication of cycloferon at the treatment of CT provided to normalization cytokines profile of the blood and production of CK in the cultures mononucleares.

IL-8 and IFN-γ as Preoperative Predictors of the Outcome of Tonsillectomy.

OBJECTIVES: Tonsillectomy (TE) and tonsillotomy (TO) due to recurrent episodes of acute tonsillitis (RAT) belong to the most frequent surgical procedures. However, an adequate objective marker predicting the outcome of TE/TO preoperatively is missing. METHODS: Patients with RAT who underwent TE/TO (n = 31) were included in this pilot study. A panel of cytokines and chemokines in serum and saliva were determined preoperatively. Health-related quality of life was assessed pre- and postoperatively by the Tonsillectomy Outcome Inventory-14. RESULTS: Health-related quality of life improved significantly after surgery. Increased serum levels of interleukin-8 (IL-8) and interferon gamma (IFN-γ) are associated with a less successful outcome. No correlation between the number of acute tonsillitis episodes and the health-related quality of life after TE or TO could be observed. CONCLUSIONS: Tonsillectomy and TO improve health-related quality of life independently from the number of past acute tonsillitis episodes. Interleukin-8 and IFN-γ in serum may serve as promising markers, predicting the benefit of TE or TO for patients preoperatively.

The correlation between EBV viral load in the palatine tonsils of patients with recurrent tonsillitis and concurrent serum titers of VCA­IgG.

Epstein­Barr virus (EBV) infection usually occurs in early childhood and can persist in palatine tonsil lymphocytes to induce tonsillitis at a later date. We have examined the presence of EBV in palatine tonsils and relationship between EBV-DNA quantity in tonsil tissues and VCA-IgG quantity in autologous sera. Tonsils were obtained from 36 patients, male 20 (55.6%), female 16 (44.4%) (mean age 7.96 ± 6.97 years), who underwent tonsils removal because of recurrent tonsillitis. Tissues were processed for real-time PCR and patient's sera were assayed to determine VCA-IgG by VCA-IgG ELISA. In 27 out of 36 cases (75%), positive EBV-DNA reaction was found. However, statistical analysis showed no correlation between EBV-DNA quantity and VCA-IgG quantity. We conclude that tonsils of children can be colonized by EBV and that virus may have a direct and indirect role in recurrent tonsillitis and nasopharyngeal carcinoma.

[Impact of alcohol abuse on the composition of serum lipids in patients with tonsillitis].

The purpose of the study was to assess the impact of alcohol abuse on the composition of serum lipids in patients with tonsillitis. The values of the serum lipid spectrum were studied in 100 alcohol abusers with Streptococcus-induced lacunar tonsillitis, 100 alcoholics without markers of viral hepatitis, and 50 healthy individuals. The effect of alcohol was shown in elevated triglyceride levels in patients with alcoholism and tonsillitis. Exposed to bacterial infection, the tonsillitis patients who abused alcohol had higher levels of phospholipids and free cholesterol and lower concentrations of free fatty acids and cholesterol esters than the alcoholics. The tonsillitis patients who abused alcohol were observed to have more considerable changes in the spectrum of phospholipids as a low relative content of lysophospholipids and higher levels of phosphatidylcholine and phosphatidylethanolamine than the alcoholics, which may be due to the predominant impact of bacterial infection.

Cytokine production in patients with recurrent acute tonsillitis: analysis of tonsil samples and blood.

The aim of this study was to examine T cell function in tonsils of patients with recurrent acute tonsillitis (RAT) or peritonsillar abscess (PTA) by analyzing the cytokine production following T cell receptor (TCR) and co-receptor stimulation with a combination of anti-CD3 and anti-CD28 antibodies. The release of IFN-γ, TNF-α, IL-2, IL-4, IL-6, IL-10 and IL-17A from isolated, stimulated T cells of 27 palatine tonsils (10 RAT, 7 PTA, 10 tonsils without inflammation) was measured via a bead-based flow cytometric analysis. The results were compared with the cytokine release of isolated peripheral T cells in a subset of the same patients (6 PTA, 4 patients without signs of inflammation in the blood). TCR stimulation increased the concentration of released cytokines in tonsil and blood as well as in different forms of inflammation and tissue with no inflammation. Stimulation increased the pro-inflammatory cytokines TNF-α, IFN-γ, and IL-2 more than the anti-inflammatory cytokines IL-4 and IL-10 in tonsil and blood samples in RAT, PTA, and samples without inflammation. Blood of patients with PTA showed a higher pro-inflammatory cytokine level compared to the samples of patients without inflammation. T cells in tonsils are fully responsive and competent for antigen-induced cytokine production in RAT and PTA. One should be aware that tonsillectomy, if indicated, might remove a functioning immune organ. Tonsillotomy might be an alternative even in adults to maintain immunological function.
