Tonsillectomy and the incidence of various types of cancer. Immunol Res 2021; 69:467-470.

Abstract
A potential connection between tonsillectomy and the development of various cancer types has repeatedly been reported in the scientific literature, but many studies have contradicted these observations. Thus, we have no clear evidence, neither to firmly support nor to refute the above-mentioned connection. Here, I suggest that the main reason for the lack of clearer evidence is that the investigations have so far mainly used incorrect sample groups. I propose that individual differences in the tonsils' involvement in immune reactions should be taken into account to solve this long-standing puzzle.

[PMID: 33720418 DOI: 10.1002/lary.29506] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 01/29/2021] [Accepted: 02/19/2021] [Indexed: 02/05/2023]
Abstract
OBJECTIVE Given the conflicting evidence regarding adenotonsillectomy and the risk of upper airway infections (UAIs), including acute pharyngitis (APT), rhinosinusitis (ARS), and otitis media (AOM), we evaluated the risk of developing UAIs following adenotonsillectomy in a childhood population. METHODS In this population-based follow-up study, we used data from the National Health Insurance Service-National Sample Cohort. The adenotonsillectomy group (n = 2,377) included patients aged <10 years who underwent an adenotonsillectomy. For every patient with APT (n = 2,309), ARS (n = 2,308), and AOM (n = 2,207) who had an adenotonsillectomy, four participants were randomly selected for the control groups (n = 9,204, n = 9,196, and n = 8,788, respectively) using propensity score matching. The number of postoperative hospital visits for UAIs was recorded for 1 to 9 years, and the equivalence test was used to compare the number of visits between the adenotonsillectomy and control groups. RESULTS There were no significant differences in the incidence of APT, ARS, or AOM at the margin of equivalence of difference (-0.5 < 95% confidence interval of difference < 0.5) between the two groups from postoperative year 1 to year 9. The hospital visits for these diseases gradually decreased over time in both groups. There was a significant decrease in the number of visits for APT, ARS, and AOM in the 5-9 years age group when compared with those in the <4 years age group (P < .01). CONCLUSION Our results suggest that adenotonsillectomy does not alter the frequency of UAIs in children. LEVEL OF EVIDENCE N/A Laryngoscope, 2021.

Abstract
BACKGROUND Although tonsillectomy is the most commonly performed surgical operation for children, its postoperative effect on the immune response was a source of debate among physicians. PURPOSE The aim of this systemic review was study the effect of tonsillectomy on children immune response. DATA SOURCES PubMed, Medline, Embase and Cochrane Library. REVIEW METHODS All relevant articles published English language addressing the effect of tonsillectomy on the immune system were included. One investigators extracted data regarding: year of the study, sample size, study design, sample size, timing of analysis, studied immune factors, result and conclusion were identified. Another investigator independently reviewed data accuracy. RESULTS Ten articles published between from January 2009 to January 2019 in about this issue that included 404 children were reviewed. All reviewed studies showed a non-significant difference between levels of indicators of the humeral immunity (IgA, IgG, IgM, C3 and C4) pre- and postoperatively. Studies that measured these indicators only after surgery, showed a non-significant difference in their levels between patients and healthy controls. Levels of indicators of cellular immunity (CD4+ , CD3+ , CD8+ , CD19+ , CD25+ , CD16+ , CD+ 56) showed slight reduction or increase in some studies but without a significant difference compared to their levels preoperatively, postoperatively at different intervals or with healthy controls. Other studies found no changes in these indicators postoperatively. CONCLUSION There was enough evidence to conclude that tonsillectomy has no negative affect on both humeral and cellular immunity of children.

Abstract
To investigate the short- and long-term impacts of adenoidectomy with/without tonsillectomy on the immune functions of young children < 3 years of age.This longitudinal prospective study included 40 pediatric patients (age <3 y) undergoing adenoidectomy with/without tonsillectomy for snoring and sleep apnea. Serum immunoglobulin IgA, IgG, IgM, complement C3, and C4 levels were measured for the status of humoral immunity; CD3+, CD4+, CD8+, CD4+/CD8+, CD19+, CD56+, CD3+CD4-CD8-, and CD3+CD4+CD8+ T cells were measured for the status of cellular immunity. Blood samples were taken at 3 time points: before surgery, 1 month after surgery (short-term), and 3 months after surgery (long-term). All patients were assessed for short-term outcome at 1-month postoperation, but only 30 patients were followed at 3 months after surgery. The incidence of recurrent respiratory tract infections and other immune-related conditions were recorded at each follow-up.The levels of IgA significantly decreased from the preoperative level at 1-month follow-up (P < .05), but still within normal range. No significant changes were found in the levels of IgA, IgG, IgM, C3, C4, CD3+, CD4+, CD8+, CD4+/CD8+, CD19+, CD56+, CD3+CD4-CD8-, and CD3+CD4+CD8+ T cell at 3-month follow-up in comparison with preoperative levels. There was also no episode of recurrent respiratory tract infection and other immune-deficiency conditions.Adenoidectomy with/without tonsillectomy may result in a reduction in individual antibodies in children <3 years of age, but did not show negative impacts on their immune functions. Also, the surgery does not lead to the increased risk of upper respiratory tract infection in these children.

Abstract
Objective: To evaluate the early stage effects of adenoidectomy with/without tonsillectomy on immune functions in children aged <3 years. Methods: Twenty-four children aged <3 years underwent adenoidectomy with/without tonsillectomy were included. The levels of IgG, IgA, IgM, C3, and C4 were measured for humoral immunity, and the levels of CD3+, CD4+, CD8+, CD19+, CD56+, CD3+CD4-CD8-, and CD3+CD4+CD8+ T cells were measured for cellular immunity before and 2 weeks after the operation. Results: The postoperative levels of IgA, IgG, IgM, C3, and C4 were significantly increased compared with the preoperative levels (P < 0.05). The levels of CD3+, CD4+, CD8+, CD56+, CD3+CD4-CD8-, and CD3+CD4+CD8+ T cells were increased, while the level of CD19+ was decreased in postoperative period compared with preoperative period. Compared with those in the control group, the preoperative levels of IgA, IgG, and CD3+CD4+CD8+ T cells were significantly increased (P < 0.05), while the levels of IgM, C3, C4 and CD3+, CD4+, CD8+, CD56+, and CD3+CD4-CD8- T cells were not significantly changed. The postoperative levels of IgA, IgG, C3, C4, CD3+CD4-CD8-, and CD3+CD4+CD8+ T cells were significantly increased (P < 0.05), while the levels of IgM, CD3+, CD4+, CD8+, and CD56+ T cells were not significantly changed compared with those in the control group. Conclusion: Adenoidectomy with/without tonsillectomy could stimulate the immune responses, which could avoid significant immune deficiency in a short period of time in children aged <3 years.

Abstract
SUMMARY Obstructive sleep apnoea syndrome can cause growth delay in children. Adeno-tonsillectomy can resolve the syndrome in most cases. The aim of our study is to examine modifications in clinical and laboratory growth and immunological parameters and food intake changes in OSAS children after surgery. Twenty-eight children with severe OSAS associated with adeno-tonsillar hypertrophy were submitted to paediatric evaluation to calculate auxologic parameters (weight, height, BMI and standard deviation scores), a blood draw to evaluate growth (GH; IGF-1) and immunological parameters (IgG; IgA; IgM) and a dietitian evaluation to calculate caloric intake before and after 3 months following adeno-tonsillectomy. Mean height and weight values in the study group were slightly inferior to same-age children mean according to the percentile values. After surgery, both height and BMI increased significantly at 3-months follow-up: mean height increased 2.93 cm (p = 0.0001); BMI values greatly increased by 0.72 kg/m2 (p = 0.009). Standard deviation scores increased significantly for height (p = 0.03), weight (p = 0.001) and BMI (p = 0.001). These values significantly increased, despite almost unchanged caloric intake between the pre- and post-surgery period (90 ± 24 vs 91 ± 27 kcal/kg/day; p > 0.05). In all children, age-related GH values were normal and did not show any significant increase, while IGF-1 values significantly increased during the study period (p = 0.01). Regarding immunological parameters, only IgA levels decreased after surgery and maintained a value that was higher than normal (> 70 mg/dL). In conclusion, children affected by adenotonsillar hypertrophy and OSAS do not show significant growth delay, but they do experience a slowdown in growth rate. After adeno-tonsillectomy, the speed of growth soon increases, as weight and growth increase notwithstanding an unchanged food intake. Moreover, surgery does not cause reduction in the efficiency of the immune system.

Abstract
OBJECTIVE To compare azithromycin (AZT) and benzathine penicillin (BP) in the treatment of recurrent tonsillitis in children. METHODS The study comprised of 350 children with recurrent streptococcal tonsillitis, 284 of whom completed the study and 162 children received conventional surgical treatment. The rest of the children, 122, were divided randomly into two equal main groups. Group A children received a single intramuscular BP (600,000IU for children≤27kg and 1,200,000IU for ≥27kg) every two weeks for six months. Group B children received single oral AZT (250mg for children≤25kg and 500mg for ≥25kg) once weekly for six months. RESULTS Both groups showed marked significant reduction in recurrent tonsillitis that is comparable to results of tonsillectomy. There were no statistical differences between group A and B regarding the recurrence of infections and drug safety after six-month follow-up. Group B showed better compliance. CONCLUSION AZT proved to be good alternative to BP in the management of recurrent tonsillitis with results similar to those obtained after tonsillectomy.

Abstract
BACKGROUND Recurrent tonsillitis is a common disease with marked evidence of affecting children quality of life (QOL) such as their progression in school and increased burden to extended families. The aim of this study was to compare the QOL outcomes after conventional dissection tonsillectomy versus azithromycin treatment in controlling recurrent tonsillitis. METHODS A double-blind, randomized clinical trial was carried out in 184 children with recurrent tonsillitis randomly divided into two groups: Group A was subjected to conventional dissection tonsillectomy, whereas Group B received single 250 mg (children ≤25 kg) and 500 mg (children ≥25 kg) of oral azithromycin once weekly. RESULTS There were no significant differences between the groups with regard to ear, nose, and throat infections during the 5-year follow-up. Better QOL was observed in both groups when compared with the pretreatment, but similar QOL in both groups QOL after treatment. CONCLUSION Azithromycin is an effective method as a prophylaxis against recurrent tonsillitis with a great benefit for better QOL outcomes.

Abstract
BACKGROUND Adenotonsillar hypertrophy can produce cardiopulmonary disease in children. However, it is unclear whether adenotonsillar hypertrophy causes atherosclerosis. This study evaluated carotid intimamedia thickness and carotid arterial stiffness in children with adenotonsillar hypertrophy. METHODS The study included 40 children with adenotonsillar hypertrophy (age: 5-10 years) and 36 healthy children with similar age and body mass index. Systolic blood pressure, diastolic blood pressure, and pulse pressure were measured in all subjects. Carotid intima-media thickness, carotid arterial systolic diameter, and carotid arterial diastolic diameter were measured using a high-resolution ultrasound device. Based on these measurements, carotid arterial strain, carotid artery distensibility, beta stiffness index, and elasticity modulus were calculated. RESULTS Carotid intima-media thickness was greater in children with adenotonsillar hypertrophy (0.36±0.05 mm vs. 0.34±0.04 mm, P=0.02) compared to healthy controls. Beta stiffness index (3.01±1.22 vs. 2.98±0.98, P=0.85), elasticity modulus (231.39±99.23 vs. 226.46±83.20, P=0.88), carotid arterial strain (0.17±0.06 vs. 0.17±0.04, P=0.95), and carotid artery distensibility (13.14±3.88 vs. 12.92±3.84, P=0.75) were similar between children with adenotonsillar hypertrophy and the healthy controls. CONCLUSIONS The present study revealed increased carotid intima-media thickness in children with adenotonsillar hypertrophy. The risk of subclinical atherosclerosis may be higher in children with adenotonsillar hypertrophy.

Abstract
BACKGROUND Tonsillectomy has been considered a treatment for IgA nephropathy (IgAN). It is aimed at removing a source of pathogens, reducing mucosa-associated lymphoid tissue and decreasing polymeric IgA synthesis. However, its beneficial effect is still controversial. In Asia, favorable outcomes have been claimed mostly in association with corticosteroids. In Europe, small, single-center uncontrolled studies have failed to show benefits. METHODS The European validation study of the Oxford classification of IgAN (VALIGA) collected data from 1,147 patients with IgAN over a follow-up of 4.7 years. We investigated the outcome of progression to end-stage renal disease (ESRD) and/or 50% loss of estimated glomerular filtration rate (eGFR) and the annual loss of eGFR in 61 patients who had had tonsillectomy. RESULTS Using the propensity score, which is a logistic regression model, we paired 41 patients with tonsillectomy and 41 without tonsillectomy with similar risk of progression (gender, age, race, mean blood pressure, proteinuria, eGFR at renal biopsy, previous treatments and Oxford MEST scores). No significant difference was found in the outcome. Moreover, we performed an additional propensity score pairing 17 patients who underwent tonsillectomy after the diagnosis of IgAN and 51 without tonsillectomy with similar risk of progression at renal biopsy and subsequent treatments. No significant difference was found in changes in proteinuria, or in the renal end point of 50% reduction in GFR and/or ESRD, or in the annual loss of eGFR. CONCLUSION In the large VALIGA cohort of European subjects with IgAN, no significant correlation was found between tonsillectomy and renal function decline.

Abstract
The IgA nephropathy (IgAN) is a very common glomerulonephritis and can result in end-stage renal disease. From a clinical point of view, IgAN is characterised by repeated events of macrohaematuria associated with infections of the upper airways. In IgAN, the IgA released by the tonsillar lymphatic tissue into blood circulation are defective in glycosylation. These aberrant IgA can reach the glomeruli and deposit into mesangium causing an inflammation with cellular proliferation. The treatment is not yet well defined: steroids and immunosuppressive drugs are suggested in cases with a progressive disease. Tonsillectomy was proposed to reduce the infective events of upper airways and the lymphatic tissue producing undergalactosylated IgA. The experiences in literature coming from Asia report positive effects of tonsillectomy on IgAN. In patients with tonsillectomy, the renal signs improved (less haematuria and proteinuria) and the renal outcome was better (slower progression of renal damage). These were uncontrolled studies and tonsillectomy was associated with steroid and immunosuppressive treatment, so it is not possible to tell the real effect of tonsillectomy. In contrast, the European studies reported that the tonsillectomy was not associated with a better outcome of IgAN. A critical review of the subject reveals that most of the papers with positive results were uncontrolled retrospective experiences, while in a randomised controlled trial paper the advantages of tonsillectomy disappeared. In conclusion, this review, in agreement with the international guidelines, concludes that tonsillectomy does not play any role in the progression of IgAN.

Abstract
IMPORTANCE The immunological sequelae of tonsillectomy in children have been a source of debate among physicians and a continuous concern for parents. Contradictory pertinent results exist in the literature. OBJECTIVE To understand the real effect of tonsillectomy on the immune system. DATA SOURCES MEDLINE, EMBASE and COCHRANE. STUDY SELECTION Articles addressing the effect of tonsillectomy on the immune system, up to Dec 2014. Related keywords and medical subject headings were used during the search. The abstracts were reviewed to determine suitability for inclusion based on a set of criteria. Manual crosscheck of references was performed. DATA EXTRACTION We checked the tests results and the conclusion of each study to classify it as supporting or refuting the hypothesis of a negative effect of tonsillectomy on the immune system. RESULTS We reviewed 35 articles, published between 1971 and 2014, including 1997 patients. Only Four studies (11.4%), including 406 patients (20.3%) found that tonsillectomy negatively affects the immune system. We performed a separate meta-analysis on various reviewed humoral and cellular immunological parameters (e.g. total and specific serum Ig's, SecIgA, cellular immunity, and Ag specific Ig). There is more evidence to suggest that tonsillectomy has no negative clinical or immunological sequalae on the immune system. Study limitations included heterogeneity in the diagnostic tools, timing of testing, indication for tonsillectomy and patients' age. CONCLUSION It is reasonable to say that there is enough evidence to conclude that tonsillectomy has no clinically significant negative effect on the immune system. It will be important for future studies to uniformly use both preoperative and control laboratory tests' levels to compare the postoperative levels with, to have short and long term follow-up levels, and to include both humoral and cellular immunity in their measurements. RELEVANCE The results should reassure both surgeons and parents that tonsillectomy has no proven clinical sequalae. If more research is to be done in the future, it should be performed in a standardized way to avoid the heterogeneity seen in the literature.

Abstract
BACKGROUND Although the tonsils contribute to first line immunity against foreign pathogens in the upper aero-digestive tract, the association of tonsillectomy with the risk of deep neck infection remains unclear. The aim of this study was to assess the incidence rate and risk of deep neck infection among patients who had undergone a tonsillectomy. METHODS This retrospective cohort study evaluated all patients who had undergone tonsillectomy between 2001 and 2009 as identified from the Taiwan National Health Insurance Research Database. For each post-tonsillectomy patient, 10 age-, sex-, and index date-matched controls without a history of tonsillectomy were randomly selected. Cox Proportional hazard model and propensity score model were performed to evaluate the association between tonsillectomy and deep neck infection after adjusting for demographic and clinical data. RESULTS There were 34 (71.6 cases per 100,000 person-years) and 174 (36.6 cases per 100,000 person-years) patients that developed deep neck infection in the tonsillectomized and comparison cohorts, respectively. After adjusting for covariates, patients who had undergone a tonsillectomy had a 1.71-fold greater risk of deep neck infection by both Cox proportional hazard model (95% confidence interval, 1.13-2.59) and propensity score model (95% confidence interval, 1.10-2.66). This association was not altered regardless of the indication for tonsillectomy (i.e. chronic/recurrent tonsillitis or sleep apnea/hypertrophy of tonsil) (p = 0.9797). CONCLUSIONS Based on our review of a nationwide cohort study we identified that the risk of deep neck infection is significantly increased among patients who have undergone a tonsillectomy. Additional research is needed to explore the possible mechanisms behind these findings.

Abstract
Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus (PANDAS) is a well-defined syndrome in which tics (motor and/or vocal) and/or obsessive compulsive disorders (OCD) consistently exacerbate in temporal correlation to a Group A beta-haemolytic streptococcal infection. In children with PANDAS, there is speculation about whether tonsillectomy or adenotonsillectomy might improve the neuropsychiatric course. Our objective was to examine whether such surgery impacted remission or, in patients without remission, modified clinical course of the disease, streptococcal antibody titers, neuronal antibodies or clinical severity of Obsessive-Compulsive Disorder (OCD) and/or tics. Study participants (n = 120) with positive PANDAS criteria were recruited, examined, and divided into surgical or non-surgery groups. The surgical group consisted of children with tonsillectomy or adenotonsillectomy (n=56). The remaining children were categorized as non-surgery (n=64). Clinical follow-up was made every 2 months for more than 2 years. Surgery did not affect symptomatology progression, streptococcal and neuronal antibodies, or the clinical severity of neuropsychiatric symptoms in these children. In conclusion, in our series clinical progression, antibody production, and neuropsychiatric symptom severity did not differ on the basis of surgical status. We cannot uphold surgical management as likely to impact positive remission rates, course of OCD/tics, or antibody concentrations in children with PANDAS.

Abstract
Tonsil hypertrophy (TH) is very common in children. Previously, it has been reported that an inverse relationship exists between adenoid hypertrophy (AH) and allergic rhinitis (AR). This study aimed to investigate the possible relationship between tonsil volume and AR diagnosis in a group of children complaining of upper airways obstruction. Globally, 171 children (91 boys; mean age, 6.6 years) were studied. Clinical visit, nasal endoscopy, and skin-prick test were performed in all patients. TH and anterior nasal obstruction were graded using the Friedman's classifications. Adenoid volume was graded using the Parikh's classification. Fifty-eight children (33.9%) had relevant TH (grades 3-4); 77 children (44.94%) had AR. There was a strong correlation (gamma = 0.564; p < 0.001) between TH and AH. Tonsil volume was inversely associated with AR diagnosis (odds ratio [OR], 0.314). Risk factors for TH were intense mucosal inflammation (pale mucous membranes) and AH (OR, 3.54 and 2.856, respectively). This study shows that large tonsils are negatively associated with allergy, whereas intense inflammation is a risk factor for TH; AH may be frequently associated with TH.

Abstract
BACKGROUND In children presenting with obsessive compulsive disorder (OCD) and/or tics, especially those with a temporal association with streptococcal pharyngitis (eg, Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus), there is speculation about whether tonsillectomy/adenoidectomy might improve the child's neuropsychiatric course. Our objective was to examine whether removal of the tonsils and/or adenoids impacted streptococcal antibody titers, the timing of onset of OCD and/or tics and the clinical severity of these symptoms. METHODS Study participants (N = 112; average age = 9.2 ± 2.4; 44 women) were recruited as part of a prospective investigation of neuropsychiatric phenomena with temporal association to streptococcal pharyngitis and examined by family history, diagnostic interview, physical examination, medical record review, psychological testing and streptococcal antibodies and divided into surgical or nonsurgical groups. The surgical group consisted of children having previously had a tonsillectomy and/or adenoidectomy (n = 32). The remaining children were categorized as nonsurgical group (n = 76). Measures of OCD and tic severity, streptococcal antibody titers and Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus classification were compared between both groups. RESULTS There were no significant differences as determined by streptococcal antibody titers, Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus classification and OCD or tic severity between the surgical and nonsurgical groups. Most participants had surgery before the onset of neuropsychiatric symptoms and surgery did not affect symptomology. CONCLUSIONS Streptococcal antibodies and neuropsychiatric symptom severity did not differ on the basis of surgical status. From these data, we cannot infer that tonsillectomy and adenoidectomy are likely to impact positively the course of OCD/tics or streptococcal antibody concentrations.

Abstract
Palatine and pharyngeal tonsils are immune reactive lymphoid organs that manifest specific antibodies and B/T-cell activity to respond to a variety of antigens. They perform humoral and cellular immune functions. The possible effects of adenotonsillectomy upon the immune system remain controversial. Objective To study the short and long-term impacts of tonsillectomy upon the cellular and humoral immunity of children. Method This longitudinal prospective study included 29 children referred to adenotonsillectomy for adenotonsillar hypertrophy. Serum IgA, IgM, and IgG and lymphocyte counts were analyzed at three points in time: before surgery, 1-2 months after surgery (short term), and 12-14 months after surgery (long term). Results TCD4+ cell counts were significantly increased shortly after surgery. IgA and IgG values were significantly reduced in the long run, but were within normal ranges for this age group. Conclusion This study indicated that adenotonsillectomy does not pose negative short or long term impacts upon the cellular and humoral immunity of children submitted to the procedure.

Abstract
OBJECTIVE To explore associated clinical factors in children with pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS). STUDY DESIGN Children with tics, obsessive-compulsive disorder, or both (n=109) were examined with personal and family history, diagnostic interview, physical examination, medical record review, and measurement of baseline levels of streptococcal antibodies. RESULTS Significant group differences were found on several variables, such that children in whom PANDAS (versus without PANDAS) were more likely to have had dramatic onset, definite remissions, remission of neuropsychiatric symptoms during antibiotic therapy, a history of tonsillectomies/adenoidectomies, evidence of group A streptococcal infection, and clumsiness. CONCLUSION The identification of clinical features associated with PANDAS should assist in delineating risks for this subtype of obsessive-compulsive disorder/tics.

Abstract
OBJECTIVE The aim of this study was to better characterize the impact of pre-transplant adenotonsillectomy in the development of graft-versus-host disease in pediatric patients undergoing allogeneic stem cell transplantation. METHODS This retrospective study involved 211 children undergoing stem cell transplantation at Duke University. Patients who had undergone transplant were characterized by age at transplant, age at adenotonsillectomy (if applicable), age at graft-versus-host disease (if applicable), average length of follow up and other factors. Statistical analyses were performed to determine the relative risks associated with each variable. RESULTS A total of 136 patients developed graft-versus-host disease and 75 did not. Average length of follow up was 2 years for GVHD and 1.7 years for non-GVHD patients. The relative risk (RR) of graft-versus-host disease was significantly increased under univariate analysis if the donor and recipient were unrelated (RR=2.1, p<0.0001) and if the HLA match was not identical (RR=1.6, p<0.001). A history of adenotonsillectomy prior to transplant did not affect the risk of developing graft-versus-host disease (RR=1.1, p=0.70). CONCLUSIONS Adenotonsillectomy prior to bone marrow transplant has no significant impact either protectively or adversely on the risk of developing graft-versus-host disease after transplantation in pediatric patients. Future studies are needed to further examine the impact of otolaryngologic surgery on pediatric patients in terms of immune system modification. Research should specifically focus on the immunological effects of surgery on patients who will be undergoing bone marrow transplant.

Abstract
OBJECTIVE The purpose of this follow-up study was to investigate the long-term effects of tonsillectomy in comparison with their short-term results. PATIENTS AND METHODS We successfully retrieved 20 out of our previously reported 37 patients who underwent tonsillectomy in our clinic 54 months ago. The blood levels of CD3+, CD4+, CD8+, CD19+, CD25+ and CD16++56+ (cellular immunity), and IgG, IgA, IgM, C3 and C4 (humoral immunity) were determined and compared with their previously reported short-term respective values. RESULTS There were no statistically significant differences between the short-term (1 month) and long-term (54 months) values of IgA, IgG, IgM and C4 levels of the patients (P>0.05). There was a slight but statistically significant decrease in complement factor C3 value compared to its the early-stage value (P<0.05) but this was not significantly different from age-matched healthy controls (P>0.05). The levels of CD4+ and CD19+ were higher and the levels of CD16++56+ and CD25+ were lower in the late-stage (54 months) compared to their early-stage values (P<0.05). When the long-term immune parameters of the tonsillectomized patients were compared with aged-match healthy controls, there were no significant differences between the levels of immunoglobulins, complements and lymphocytes (IgA, IgG, IgM, C3, C4, CD3+, CD4+, CD8+, CD19+, CD25+, CD16++56+) (P>0.05). CONCLUSION The results of this long-term follow-up study indicate that tonsillectomy do not compromise the immune functions of children as humoral and cellular immunity of patients recovered compared to their early-stage immune status (1 month), as they have similar immune capacity compared to their age-matched healthy controls at both early- and late-stages. Although a small sample of patients enrolled, our results are of importance with respect to the reassuring in settling the widely held urban myth that tonsillectomy compromises life long immunity.

Abstract
CONCLUSION Membrane-bound mucin MUC4 represents the predominant mucin expressed in the adenoid epithelium followed by MUC5AC (gel-forming mucin). This may suggest that membrane-bound mucins could be involved in pathogen binding and immunological stimulation. OBJECTIVES The aim of this study was to investigate mucin expression in hypertrophic adenoids. MATERIALS AND METHODS Adenoidal samples were obtained from 12 children. The expression of eight mucin genes, MUC1-4, MUC5AC, 5B, 6 and 7 was studied by in situ hybridization utilizing digoxigenin-labelled oligonucleotide probes. RESULTS The dominant mucin genes were MUC4, 3 and 5AC, while MUC1, 2, 5B and 7 were sparsely expressed and MUC6 was not expressed. Expression patterns were very different from those in the upper airways. Most samples expressed two membrane-bound mucins (MUC4 and 3) and one secretory mucin (MUC5AC).

Abstract
OBJECTIVES Compare the effects of partial tonsil resection using a radiofrequency technique, tonsillotomy (TT), with total tonsillectomy (TE, blunt dissection) after 1 and 3 years. Compare frequency of relapse in snoring or infections and possible long-term changes in behavior among TT children with those in TE children. METHOD Ninety-two children (5-15 yr) randomized to TT (n = 49) or TE (n = 43) groups because of obstructive problems with or without recurrent tonsillitis. One year after surgery, general health, degree of obstruction, history of infections, and behavior were investigated using two questionnaires, the Qu1 and Child Behavior Checklist, as well as an ENT visit. After 3 years, two questionnaires, Qu2 and the Glasgow Children's Benefit Inventory, were answered by mail. RESULTS : After 1 year, both groups were in good health. The effect on snoring and total behavior was the same for both groups, and the rate of recurrence of infections was not higher in the TT group. After 3 years, two children in the TT group were tonsillectomized (4%, 2/49), one because of peritonsillitis and another because of increased snoring. Otherwise, no differences existed between the groups in general health, snoring, or number of infections. CONCLUSION Removing only the protruding parts of the tonsils has the same beneficial long-term effect on obstructive symptoms and recurrent throat infections as complete TE in the majority of cases. The need for re-operation is low; therefore, it appears inadvisable to follow the current common practice of routinely removing the whole tonsil given its higher morbidity and risk for serious complications.

Abstract
We evaluated the differences in histological and immunological findings in children with recurrent tonsillitis and tonsillar hyperplasia and assessed the risk for relapsing tonsillar hyperplasia or recurrent tonsillitis after tonsillotomy in a prospective clinical study. Sixty-four children with recurrent tonsillitis underwent traditional (total) blunt dissection tonsillectomy between October 2003 and July 2004. Partial tonsillectomy (tonsillotomy) using CO(2)-laser technique was performed on 49 children with tonsillar hyperplasia and no history of recurrent tonsillitis between August 2003 and March 2005. The present study compares preoperative serum anti-streptolysin-O antibody and immunoglobulin levels (IgG, IgA and IgM), C-reactive protein levels (CRP) and blood leukocyte counts of the two study groups. Additionally the tonsillar tissue removed by tonsillotomy or tonsillectomy was histologically examined in order to determine the grade of hyperplasia, chronic inflammation and fibrosis. Furthermore, the grade of fresh inflammation within the tonsillar crypts of the specimens was analysed. The parents of 40 patients treated by laser tonsillotomy were surveyed in average 16 months. There was no statistically significant difference in preoperative serum anti-streptolysin-O antibody and immunoglobulin levels, C-reactive protein levels and blood leukocyte counts between the two study groups. All specimens showed the histological picture of hyperplasia. There was no statistically significant difference in the grades of hyperplasia between the two study groups. Signs of fresh but mild inflammation within the tonsillar crypts could be found in over 70% of both study groups. Fibrosis only occurred in children with recurrent tonsillitis (9%). In all specimens signs of chronic inflammation could be detected. The histological examinations of specimens from children with repeated throat infections more frequently showed a moderate chronic inflammation of the tonsillar tissue. Two of forty patients treated by tonsillotomy required a subsequent tonsillectomy due to a recurrence of tonsillar hyperplasia but no recurrent tonsillitis occurred. Tonsillotomy with CO(2)-laser technique is an effective surgical procedure with a long-lasting effect in patients with tonsillar hyperplasia. The benefits over conventional tonsillectomy are a lower risk for postoperative haemorrhage, reduced postoperative morbidity and accelerated recovery. Even in children with no history of recurrent tonsillitis signs of chronic inflammation histologically can be found in specimens after tonsillotomy. The occurrence of recurrent tonsillitis after tonsillotomy is rare, however. A low incidence of relapsing tonsillar hyperplasia after tonsillotomy should be expected. Preoperative laboratory investigations show few differences in patients with tonsillar hyperplasia and recurrent tonsillitis. Components of the antimicrobial defense system are also produced by chronically infected tonsils. Therefore tonsillotomy with CO(2)-laser could also be an option in some patients with mild symptoms of recurrent tonsillitis.

Abstract
BACKGROUND It remains controversial whether pediatric adenotonsillectomy ultimately results in decreased serum immunoglobulin levels and if so whether such a decrease is associated with increased susceptibility to upper respiratory tract infections (URIs). OBJECTIVE To evaluate changes in serum immunoglobulin levels in relation to occurrence of URIs in children participating in a randomized controlled trial on the effectiveness of adenotonsillectomy. METHODS A total of 300 children aged 2 to 8 years, with symptoms of recurrent throat infections or tonsillar hypertrophy, were randomly assigned to either adenotonsillectomy or watchful waiting (WW). Serum samples were collected at baseline and at 1-year follow-up. Occurrence of throat infections and other URIs during first-year follow-up was recorded in a diary by the child's parents. RESULTS Paired serum samples were available for 123 children (63 in the adenotonsillectomy group and 60 in the WW group). IgG1 and IgG2 levels decreased but remained within the reference range for age in both study arms. IgM and IgA levels decreased as well but remained elevated. The IgA level in the adenotonsillectomy group decreased in significantly greater degree compared with the WW group, but this difference disappeared in cases where children experienced frequent URIs. In general, no relation between immunoglobulin levels and the number of throat infections or URIs at 1-year follow-up was found. CONCLUSIONS Immunoglobulin levels of children undergoing adenotonsillectomy decreased from elevated to slightly elevated or reference values for age during 1-year follow-up irrespective of treatment (adenotonsillectomy or WW). IgA showed a greater decrease in the adenotonsillectomy group but rose to levels comparable with the WW group in cases of frequent URIs. This finding indicates that the remaining mucosa-associated lymphoid tissue can compensate for the loss of tonsil and adenoid tissue.

Abstract
Childhood OCD often develops into a chronic illness that lasts decades. Proof that some type of immunotherapy (such as antibiotic prophylaxis) could significantly reduce recurrence or exacerbation of symptoms of OC or tics would suggest a supportive role for immune triggers in the onset or worsening of these conditions and provide additional tools for improving outcome. The validity of PANDAS will continue to be questioned, however,because demonstrating a clear causation will be difficult on a background ofa common childhood illness. Along with the previously mentioned immuno-therapy study, validation of the PANDAS phenotype (broadly interpreted)would be advanced from new and continued research in the following areas: (1) prospective studies to identify infectious triggers in the onset and exacerbations of OCD spectrum disorders, (2) biological measures for immune and genetic susceptibility, and (3) large scale epidemiological studies demonstrating the relationship between infection and OCD spectrum disorders. The assimilation of these study results should allow for elucidation of the immune system's role in the onset and maintenance of OCD.

Abstract
OBJECTIVE Human palatine tonsils and the nasopharyngheal tonsil are the largest components of the Waldeyer's ring. Subepithelial and intraepithelial lymphocytes of human adenoids and tonsils are responsible for the local and the systemic immune response. We studied the cytokine production by lymphoid cells isolated from 16 nasopharyngeal tonsils (adenoid) and 9 palatine tonsils surgically removed by from 25 children (aged from 4 to 15 years) suffering from tonsil hypertrophy. METHODS We evaluated (by the cytometry method, using BD Bioscience kits, San Diego, CA) the concentration of IL-2, IL-4, IL-5, IL-10, TNF(alpha) and IFN(gamma) released from human peripheral blood mononuclear cells (MC) (activated or not activated by phytohaemagglutinin (PHA)) cultured in vitro during 72 h. The fluorescence-activated cell sorter (FACS) analysis was also performed and the percentage of mononuclear cells (unstimulated or activated by phorbol acetate during 24 h) stained with the monoclonal antibodies anti-CD3 containing the intracellular cytokines was calculated. RESULTS The increased secretion of IL-2, IL-4, IL-5, TNF(alpha) and IFN(gamma) from PHA activated palatine origin immune cell cultures, as compared to adenoids, was revealed. The higher mobilization (Delta%) of CD3+ T-lymphocytes containing IL-12 in palatine cell cultures (798.5+/-276.29%), in comparison with to the adenoids (298.5+/-49.16%; p< or =0.05), was also noted. CONCLUSION In palatine tonsils, as compared to adenoids, the cellular immune (Th1) response dominates over humoral immune (Th2) reaction.

Abstract
INTRODUCTION Lymphoid tissue from Waldeyer's ring produces all types of immunoglobulins, mainly G and A, and between 4 to 10 years, of age. In other words, the age in which the adenoid and tonsillar surgery is carried out. Our study tries to analyze the impact of the tonsillar surgery on the serum levels of immunoglobulins. MATERIAL AND METHODS We present a prospective study with 89 healthy children aged between 4 to 10 years. Immunoglobulin G, A and M levels were measured preoperatively, at a month and at four months after adenoidectomy and/or tonsillectomy. RESULTS Serum IgG levels dropped after surgery, but partially recovered four months later. IgA dropped less significantly and IgM did not change its levels. No one of the studied inmunoglobulins dropped below the normal serum levels. DISCUSSION/CONCLUSIONS Adenoid and tonsilar surgery cause a fall of postoperative immunoglobulin G and A serum levels, partially recovering after four months. Serum levels never dropped below normal levels, and of the studied children suffered a postoperative disease due to immunodeficiency.

Abstract
OBJECTIVE The purpose of this study was to investigate the changes in the humoral and cellular immunity of patients with chronic tonsillitis before and 1 month after tonsillectomy. PATIENTS AND METHODS 37 patients scheduled for tonsillectomy were enrolled in this study. The levels of CD3+, CD4+, CD8+, CD19+, CD25+ and CD16+ + 56+ were measured for cellular immunity, and levels of IgG, IgA, IgM, C3 and C4 were measured for humoral immunity in blood samples taken from these patients before and 1 month after the operation. RESULTS The levels of CD3+, CD8+ and CD19+ were reduced in post-operative period as compared to pre-operative period but this was not statistically significant (P > 0.05). However it was found that the level of CD4+ was significantly increased while the level of CD25+ was reduced (P < 0.05) in the post-operative period. There were statistically significant differences between pre- and post-operative levels of immunoglobulins, C3 and C4, which were decreased after tonsillectomy (P < 0.05), but these levels were comparable with those of the control group. CONCLUSION The results from the present study indicate that humoral and cellular immunity of patients undergoing tonsillectomy were decreased in the early period and came to normal later. The cellular and humoral immune responses are stimulated in patients with tonsillitis, and tonsillectomy removes this stimulus without negatively affecting the patient's immune functions.
