Abstract
BACKGROUND Immune responses, especially type 2 immunity, might be related to the prevalence of thyroid nodules, while the key regulators and potential pathways are remaining largely unknown. In addition, the immune status of individuals could be affected by mixed metabolic background. Herein our aim was to investigate the adjusted association between ultrasound-diagnosed low risk thyroid nodules and immune responses, excluding the interference of metabolic effects on immunity. METHODS We retrospectively enrolled 1764 subjects who underwent a thorough thyroid ultrasound examination. To eliminate the interference of confounders, we used propensity score matching (PSM) to match age, gender, cigarette smoking and alcohol drinking, parameters that are related with metabolic syndrome (MetS). Then the potential effectors of immune responses involved in the laboratorial assays were evaluated. Binary logistic regression analysis was used to assess the independent predictors of thyroid nodules in a multivariate manner. RESULTS The 1172 subjects were remained after PSM, and differences of demographic background between subjects with and without thyroid nodules were eliminated. Metabolic parameters comprising blood pressure, fasting blood glucose, total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein and serum uric acid were shown no significant difference between post-PSM subjects with and without thyroid nodules. Among the biochemistry and hematological parameters, white blood cell count and the positive rate of eosinophil percentage were increased in subjects with thyroid nodules than in those without thyroid nodules. In contrast, the positive rate of basophil percentage was lower in subjects with thyroid nodules than in those without thyroid nodules. In addition, the thyroid function test results showed that subjects with thyroid nodules had higher positive rates of antithyroglobulin antibody (TgAb) and antithyroid peroxidase antibody (TPOAb) than subjects without thyroid nodules. The logistic regression analysis indicated that the positive value of TgAb as well as high level of white blood cell count and BMI could serve as independent risk factors of thyroid nodules. CONCLUSIONS The type 2 immune responses mediated by increased level of eosinophils, along with positive value of TgAb and TPOAb were associated with the presence of thyroid nodules. In addition, the potential role of basophils in protecting against thyroid nodules and the pathogenesis of immune-metabolic status remains to be elucidated.

Abstract
Thyroglobulin antibody (TgAb) is a class G immunoglobulin and a conventional marker for thyroid autoimmunity. From a clinical perspective, TgAb is less useful than thyroid peroxidase antibodies for predicting thyroid dysfunction. However, TgAb is found more frequently in differentiated thyroid cancer (DTC) and can interfere with thyroglobulin (Tg) measurements, which are used to monitor the recurrence or persistence of DTC. Recent studies suggested a small but consistent role for preoperative TgAb in predicting DTC in thyroid nodules, and in reflecting adverse tumor characteristics or prognosis, including lymph node metastasis, but this is still controversial. Postoperative TgAb can serve as a biomarker for remnant thyroid tissue, so follow-up measures of TgAb are useful for predicting cancer recurrence in DTC patients. Since high serum TgAb levels may also affect the fine needle aspiration washout Tg levels from suspicious lymph nodes of DTC patients, it is important to use caution when interpreting the washout Tg levels in patients who are positive for TgAb.

Abstract
Thyroid cancer is the most frequent cancer among endocrine tumors, and account for approximately 1% of all malignancies. Recent literature has suggested an association between autoimmune thyroiditis and papillary thyroid cancer. The aim of the study was to choose the role of preoperative thyroid auto-antibodies as a predictive marker that could distinguish benign and malignant thyroid nodules and any other occult malignancy. This cross sectional study was done from July 2012 to June 2014 in department of Surgery Sir Salimullah Medical College & Mitford Hospital (SSMC&H) in collaboration with department of Otolaryngology SSMC&H, Bangabandhu Sheikh Mujib Medical University, Dhaka Medical College and Bangladesh Medical College of Dhaka city. Inclusion criteria were all patients presenting with thyroid swelling. For this study, 116 patients of thyroid swelling were studied by detailed history, clinical examination, thyroid hormone assay (serum T₃, T₄, TSH), ultrasonogram to detect single or multiple nodules, solid or cystic condition of nodules, thyroid scan to see functional status of gland, FNAC to detect benign or malignant condition preoperatively, thyroid auto antibodies (Tg-Ab and TPO-Ab) and histopathological examinations. FNAC outcomes were compared with anti-thyroid auto antibodies (ATA) and histopathological reports. In this study it showed that out off 89 benign classes 53 were with raised and 36 were with normal anti-thyroid auto anti-bodies (Tg-Ab+TPO-Ab). Among the raised 53 patient only 14(26.41%) were proved malignant in histopathological examination. On the other hand out off 36 normal anti-thyroid auto anti-bodies (Tg-Ab+TPO-Ab), 5(13.88%) became malignant histopathologically. In the cytological malignant group out off 17 patient 8 (47.05%) were with normal anti-thyroid auto anti-bodies (Tg-Ab+TPO-Ab) and 09(52.95%) were with raised anti-thyroid auto anti-bodies (Tg-Ab+TPO-Ab) and all of them were histologically malignant. It was observed that FNAC with high level of anti-thyroid auto anti-bodies (Tg-Ab+TPO-Ab) will be suspicious for malignancy but not statistically significant in this study odds ratio for anti-thyroid auto anti-bodies (Tg-Ab+TPO-Ab) within normal and raised were 0.78(0.501-1.214) and 1.23(0.807-1.89) respectively. In the series sensitivity, specificity, positive predictive value and negative predictive value of thyroid auto antibodies and FNACs were done by the ROC curve. It showed that PPV was highest 96% for FNAC and for Tg-Ab and TPO-Ab it was 27% and 24% respectively. In this study thyroid auto-antibodies were raised in both benign and malignant conditions. TPO-Ab was more raised than Tg-Ab in our country with malignant conditions of thyroid. Thyroid auto anti-bodies could not predict the malignant condition of thyroid. In our study the benign cytology with raised antithyroid auto antibodies showed risk to be malignant outcome in histopathology.

Abstract
Galectins (S-type lectins) are an evolutionarily-conserved family of lectin molecules, which can be expressed intracellularly and in the extracellular matrix, as well. Galectins bind β-galactose-containing glycoconjugates and are functionally active in converting glycan-related information into cell biological programs. Altered glycosylation notably occurring in cancer cells and expression of specific galectins provide, indeed, a fashionable mechanism of molecular interactions able to regulate several tumor relevant functions, among which are cell adhesion and migration, cell differentiation, gene transcription and RNA splicing, cell cycle and apoptosis. Furthermore, several galectin molecules also play a role in regulating the immune response. These functions are strongly dependent on the cell context, in which specific galectins and related glyco-ligands are expressed. Thyroid cancer likely represents the paradigmatic tumor model in which experimental studies on galectins' glycobiology, in particular on galectin-3 expression and function, contributed greatly to the improvement of cancer diagnosis. The discovery of a restricted expression of galectin-3 in well-differentiated thyroid carcinomas (WDTC), compared to normal and benign thyroid conditions, contributed also to promoting preclinical studies aimed at exploring new strategies for imaging thyroid cancer in vivo based on galectin-3 immuno-targeting. Results derived from these recent experimental studies promise a further improvement of both thyroid cancer diagnosis and therapy in the near future. In this review, the biological role of galectin-3 expression in thyroid cancer, the validation and translation to a clinical setting of a galectin-3 test method for the preoperative characterization of thyroid nodules and a galectin-3-based immuno-positron emission tomography (immuno-PET) imaging of thyroid cancer in vivo are presented and discussed.

Abstract
BACKGROUND Granulomatous disease in the thyroid gland has been linked to viral, bacterial and autoimmune etiologies. The most common granulomatous disease of the thyroid is subacute granulomatous thyroiditis, which is presumed to have a viral or post-viral inflammatory cause. Bacterial etiologies include tuberculosis, actinomycosis, and nocardiosis, but are extremely rare. Disseminated actinomycosis and nocardiosis more commonly affect organ-transplant patients with the highest susceptibility within the first year after transplant surgery. CASE A 45-year-old African American male, who received his third kidney transplant for renal failure secondary to Alport Syndrome, presented with numerous subcutaneous nodules and diffuse muscle pain in the neck. Further workup revealed bilateral nodularity of the thyroid. Fine needle aspiration of these nodules demonstrated suppurative granulomatous thyroiditis. Subsequent right thyroid lobectomy showed granulomatous thyroiditis with filamentous micro-organisms, morphologically resembling Nocardia or Actinomyces. CONCLUSION Disseminated granulomatous disease presenting in the thyroid is very rare, and typically afflicts immune-compromised patients. The overall clinical, cytologic and histologic picture of this patient strongly points to an infectious etiology, likely Nocardia, in the setting of recent organ transplantation within the last year.

Abstract
BACKGROUND Establishing the preoperative diagnosis and long-term prognosis of differentiated thyroid cancer (DTC) remain challenging in some patients. Myeloid-derived suppressor cells (MDSC) are tumor-induced cells mediating immune tolerance that are detectable in the peripheral blood of cancer patients. The authors previously developed a novel clinical assay to detect the phenotypes of two human MDSC subsets in peripheral blood, and hypothesize that higher MDSC levels measured by this assay correlate positively with both malignancy and worse patient outcomes. METHODS A prospective observational pilot study was performed of patients undergoing thyroidectomy for a solitary thyroid nodule. The presence of a thyroid nodule >1 cm was confirmed sonographically, and fine-needle aspiration biopsy performed prior to surgery in all cases. Peripheral blood collected preoperatively was analyzed using a novel flow cytometry-based immunoassay to detect and quantify two subsets of human MDSC. Circulating MDSC levels were compared by histopathologic diagnosis, stage, and presence of persistent disease after treatment. RESULTS Of 50 patients included in this study, MDSC measurement was successful in 47 (94%). One patient was found to have a concurrent cancer, leaving 46 patients for primary analysis. The cytologic diagnoses were benign in five (10.8%), atypia or follicular lesion of undetermined significance in five (10.8%), suspicious for follicular neoplasm in five (10.8%), suspicious for malignant in three (6.5%), and malignant in 28 (60.1%) of the 46 nodules. Final histopathology was benign in 11 (24%) and DTC in 35 (76%), encompassing 34 PTC cases and one follicular thyroid carcinoma. Mean percentages of CD11b(+)HLA-DR(low)HIF1a(+) MDSC (CD11b(+)MDSC) were 14.0 ± 6.2% and 7.9 ± 3.6% in DTC versus benign nodules, respectively (p < 0.005). A cutoff of 12% yielded a specificity of 0.91, a sensitivity of 0.72, and a likelihood ratio of 7.9. Mean CD11b(+)MDSC levels increased linearly with higher TNM stage (p < 0.01), and were 19.4 ± 5.4 in patients with persistent cancer after surgery compared with 13.2 ± 6.8 in those without evidence of disease (p < 0.05). CONCLUSION MDSC measurement using this flow cytometry-based assay represents a novel approach for preoperatively assessing malignancy risk and cancer extent in patients with thyroid nodules. While further validation is needed, these data suggest that MDSC assessment may serve as a useful adjunct when cytology is indeterminate, and predict tumor stage and recurrence risk in cases of thyroid cancer.

Abstract
This prospective study investigates the relationship between Hashimoto's thyroiditis (HT) and thyroid cancer (TC) in patients with thyroid nodules (TNs). We prospectively examined 2100 patients with 2753 TNs between January 5, 2010 and August 15, 2013. A total of 2023 patients with 2669 TNs met the inclusion criteria of TN ≥5 mm and age ≥18 years. Each patient had blood drawn before fine-needle aspiration biopsy (FNAB) for the following measurements: TSH, free thyroxine, free tri-iodothyronine, thyroid peroxidase antibody (TPOAb), and antithyroglobulin antibody (TgAb). Diagnosis of TC was based on pathology analysis of thyroidectomy tissue. The associations of TC with the independent variables were determined by univariate and multivariate logistic regression analysis and reported as adjusted odds ratio (OR) with 95% CI. A total of 248 malignant nodules were found in 233 patients. There was an association of TC with both increased serum TgAb concentration and age<45 years. An elevated serum TgAb concentration was found in 10.2% of patients (182 of 1790) with benign nodules as compared with 20.6% of patients (48 of 233) with malignant nodules (P≤0.0001). TgAb (OR=2.24: CI=1.57, 3.19) and TSH ≥1 μIU/ml (OR (95% CI)) OR: 1.49 (1.09, 2.03) were significant predictors of TC in multivariate analysis controlling for age and gender. TC was not associated with serum concentrations of TPOAb. In patients with TN, elevated serum concentration of TgAb and TSH ≥1 μIU/ml are independent predictors for TC. The association between HT and TC is antibody specific.

Abstract
BACKGROUND Even though the presence of antithyroglobulin antibodies (TgAbs) represents a significant problem in the follow-up of patients with differentiated thyroid cancer (DTC), the current guidelines on the management of DTC that have been published in recent years contain no text concerning the methods to be used for detecting such antibody-related interference in thyroglobulin (Tg) measurement or how to manage TgAb-positive patients in whom Tg cannot be used reliably as a tumor marker. AIM An international group of experts from the European Thyroid Association Cancer Research Network who are involved in the care of DTC patients met twice to form a consensus opinion on how to proceed with treatment and follow-up in TgAb-positive DTC patients based on the available evidence in the literature. Here we will report on the consensus opinions that were reached regarding technical and clinical issues. RESULTS This clinical opinion article provides an overview of the available evidence and the resulting consensus recommendations. The current literature does not provide sufficient data for giving evidence-based answers to many questions arising in the care of TgAb-positive DTC patients. Where insufficient evidence was available, a thorough discussion by a group of physician-scientists, all of whom have a distinguished track record in thyroid cancer care, was held to arrive at a consensus expert opinion. The questions and answers discussed were then summarized into an algorithm for the management of TgAb-positive patients. CONCLUSION We were able to define 26 consensus expert recommendations and a resulting algorithm for the care of TgAb-positive DTC patients.

Abstract
BACKGROUND Thyroid nodules are common among adults, and accurate diagnosis is critical in for management decisions. Ultrasound and fine needle aspiration cytology are the most common methods to evaluate nodules, but they are not practical for screening large numbers of patients because of cost and time considerations. OBJECTIVE The aim of this study was to isolate an autoantibody to tumour antigen, WD repeat domain 1 (WDR1), and evaluate its diagnostic sensitivity and specificity for thyroid neoplasms. PATIENTS AND METHODS We investigated serological biomarkers in patients with thyroid carcinoma who had a poor prognosis. Using a serological analysis of recombinant cDNA expression cloning (SEREX) strategy, we isolated WDR1 and its specific autoantibody in the sera of patients with undifferentiated thyroid carcinoma (UTC). We examined using indirect ELISA, the titre of the anti-WDR1 antibody (AWA) in 54 study patients: 10 with UTC, 20 with papillary thyroid carcinoma (PTC), 17 with benign thyroid nodule (BTN), 7 with autoimmune thyroid disease (AITD), as well as 38 controls (N). RESULTS WDR1 was ubiquitously expressed in various types of thyroid tissues. However, the titre of AWA in UTC and PTC was significantly higher than that in BTN, AITD and N (P < 0·001). No significant correlation was observed between thyroid function, serum thyroglobulin and tumour diameter. The cut-off value estimated using ROC to differentiate malignancies from others was 0·95 (sensitivity 96·7%, specificity 91·9%, AUC 0·969, P < 0·001). CONCLUSIONS Anti-WDR1 antibody could be a novel approach for serological screening of PTC and UTC, and could be an efficient and inexpensive biomarker.

Abstract
AIM To assess the relevance of thyroid autoimmunity and TSH as risk factors for malignancy in thyroid nodules (TN). SUBJECTS AND METHODS Retrospective analysis on 2053 patients with single/prevalent TN submitted to fine needle aspiration cytology (FNAC). Anti-thyroid autoantibodies (ATA) [anti-thyroperoxidase (TPOAb), anti-thyroglobulin (TgAb)] and TSH were measured. Cytology was classified as benign (class II), indeterminate (class III), and suspicious or malignant (class IV). Histology was available in 301 patients. Associations of malignancy with independent variables were determined by multivariate logistic regression analysis. RESULTS Higher prevalence of class IV (14.2% vs 6.8%: p<0.001) and class III (23.5% vs 17.1%: p<0.001) were found in ATA+ vs ATA- TN. Histology confirmed increased prevalence of cancer in ATA+ (p<0.05) TN and in those with diffuse lymphocytic thyroid infiltration (p<0.05). Interestingly, the prevalence of malignancies observed in operated class III nodules was strikingly lower in ATA+ (1/20, 5%), than in ATA- patients (34/67, 50.7%; p<0.001). Increased independent odds ratio (OR) for malignancy was conferred by any ATA [OR 2.21; 95% confidence interval (CI)=1.49-3.29, p<0.0001]; TPOAb (OR 2.15; CI=1.42-3.25, p<0.0001) and TgAb (OR 1.67; CI=1.05-2.67, p<0.05), by serum TSH>1.0 μUI/ml (OR 1.95; CI=1.01-3.76, p<0.05), and by young age (10-29 yr: OR 2.09; CI=1.02-4.26, p<0.05). A formula was calculated to assess the relative contribution of ATA, TSH, and age to the risk of TN malignancy. CONCLUSIONS Both thyroid autoimmunity and increased TSH represent independent risk factors for TN malignancy.

Abstract
BACKGROUND Percutaneous ethanol injection (PEI) is used to treat cystic or mixed benign thyroid nodules. This treatment can result in rare complications, and three cases of Graves' disease (GD) without Graves' ophthalmopathy (GO) have been reported after PEI treatment of toxic thyroid adenomas. Here we present a 55-year-old male patient who developed GD and severe GO after PEI treatment of a mixed cystic-solid, nontoxic thyroid nodule. PATIENT FINDINGS Six months after PEI, the nodule volume had decreased from 8.9 to 3.0 mL, but we observed severe hyperthyroidism with elevated serum free triiodothyronine, free thyroxine, and thyrotropin receptor antibody levels. We also observed ophthalmopathy with symmetrical orbit and soft tissue involvement (grade b/c) and a clinical activity score of 4/7. The diagnosis of GO was confirmed by bilateral corneal damage, increased intraocular pressure on upgaze, and inconstant diplopia. A computed tomography scan showed that the inferior, medial, and superior extraocular muscles were bilaterally enlarged, the perineural space at the orbital cone was slightly reduced and the ophthalmic vein was congested. SUMMARY A cause-effect relationship between PEI and GD/GO was likely in this patient because of the temporal sequence. Although the mechanism was unknown, we speculated that the thyroid tissue damage caused by PEI released a large amount of antigenic materials from follicular thyroid cells, including thyrotropin receptor protein, which triggered the autoimmune inflammatory response against the thyroid itself and the orbital soft tissues. The patient did not have any risk factors for either GD or GO. CONCLUSIONS This observation raises the concern, therefore, that unpredictable and severe complications, such as GD and GO, may occur in a few patients treated with PEI.

Abstract
OBJECTIVES The aim of our study was to evaluate the possible association between autoimmunity and thyroid nodular disease (TND). DESIGN AND SETTING We conducted a study on 58 patients who were treated in outpatient setting at the Department of Endocrinology, Metabolism and Internal Medicine. Serum samples were analyzed for TSH concentration and anti-TPO antibodies titers. Thyroid ultrasonography was performed in each subject in order to evaluate volume of the gland, and the number and size of nodules. RESULTS TND occurred in 70% of anti-TPO positive subjects and in 57.9% of anti-TPO negative subjects, but statistical analysis did not demonstrate a significant concordance between the presence of anti-TPO antibodies and prevalence of TND (p>0.05). We showed that the mean (0.82 vs 0.75; p=0.49), minimal (0.2 vs 0.3; p=0.89) and maximal (2.7 vs 2.4; p=0.49) diameters of a nodule were similar in both groups. Solely in anti-TPO positive patients, anti-TPO titers positively correlated with the number of nodules (p=0.04). CONCLUSION Our results favor the role of autoimmunity in TND development although associations between thyroid nodules and thyroid autoimmunity are complicated and may be the subject of much controversy. Increased anti-TPO may influence the number of nodules rather than the presence of TND itself.

Abstract
The diagnostic and prognostic role of thyroid ultrasound (TUS) in pregnant women positive for antibodies to thyroperoxidase (TPOAb) is unclear. The aim of our study was to compare the relation of ultrasound thyroid texture to the thyroid laboratory tests in pregnant women and controls. Using a semi-quantitative assessment we compared TUS in two groups of women with positive TPOAb and/or with thyroid dysfunction (TSH out of 0.06-3.67 mIU/L): 186 women in 1(st) trimester of pregnancy recruited from universal screening and 67 asymptomatic age-comparable non-pregnant non-postpartum women recruited from screening of general population (controls). Women with previous history of thyroid diseases were excluded. Only 64/131 (48.9 %) of TPOAb-positive pregnant women were TUS-positive (TUS with autoimmune pattern) in comparison with 35/49 (71.4 %) TPOAb-positive controls (p <0.011). Pregnant women had more often TSH >10.0 mIU/L if they were TPOAb-positive/TUS-positive as compared to those TPOAb-positive/TUS-negative (8/64 (12.5 %) vs. 0/67 (0 %), p = 0.009). The prevalence of preterm deliveries among TPOAb-positive women was significantly lower if TPOAb-positivity was not accompanied by TUS-positivity (2/67 (3.0 %) vs. 10/64 (15.6 %) in TPOAb-positive/TUS-positive women, p = 0.028). In conclusion, nearly half of the TPOAb-positive pregnant women did not have an autoimmune pattern in TUS. Normal TUS image in TPOAb-positive pregnant women might be a protective factor for preterm delivery.

Abstract
BACKGROUND The association between autoimmune thyroiditis (AIT) and thyroid cancer is still not clear despite many previous reports. This study investigated whether serologic thyroid antibodies are predictive of thyroid cancer in patients with thyroid nodules. METHOD We retrospectively reviewed records of patients with thyroid nodules evaluated by ultrasonography-guided fine-needle aspiration cytology at our institution between January 2006 and December 2008. Thyroid autoimmunity was assessed by measuring thyroglobulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb). The final outcome deciding a benign or malignant status involved a combination of cytology and histology. RESULTS Of the 1638 patients, malignant nodules had a higher rate of positive TgAb (30.8% vs. 19.6%; p < 0.001) and elevated thyrotropin (TSH) levels (2.5 +/- 2.8 mIU/L vs. 2.1 +/- 2.0 mIU/L; p = 0.021) than benign nodules. The rate of positive TPOAb was not higher in malignant nodules, although both TPOAb and TgAb were well correlated with TSH levels and histological AIT. In the multivariate analysis, a positive TgAb was significantly associated with thyroid cancer (odds ratio [OR] = 1.61, 95% confidence interval [CI] 1.12-2.33) with upper tertile of normal range of TSH levels (OR = 1.72, 95% CI 1.12-2.63) and above normal range of TSH levels (OR = 1.98, 95% CI 1.06-3.70). CONCLUSION We report for the first time that a positive serum TgAb test was an independent predictor for thyroid malignancy in thyroid nodules along with serum TSH levels regardless of the presence of AIT. Our results suggest that TgAb measurement could give additional information for predicting malignancy in cytologically indeterminate thyroid nodules in conjunction with clinical risk factors and TSH levels.

Abstract
OBJECTIVE To analyze the possible association between Hashimoto's thyroiditis (HT) and cervical lymphadenopathy in cases diagnosed by fine needle aspiration cytology. STUDY DESIGN Among the patients referred to our laboratory for ultrasound-guided fine needle aspiration cytology of thyroid nodules (USG-FNAC), cases of HT associated with cervical lymphadenopathy were evaluated. RESULTS Between February 2001 and May 2007, HT was diagnosed in 94 (11%) of a total of 856 thyroid USG-FNAC cases. Among these cases, 22 (23%) were associated with single/ multiple cervical lymphadenopathy. In all cases, FNAC of the lymph nodes was consistent with reactive lymphoid hyperplasia. Anti-TPO and anti-Tg antibody results were obtained in 14 of 22 cases with HT. Among these cases, 12 showed positive values. CONCLUSION Clinicians and cytopathologists who encounter thyroid nodules with cervical lymphadenopathy should also include the possibility of HT in the differential diagnosis. A literature search disclosed no report regarding the possible association between HT and cervical lymphadenopathy. Considering the limitations due to lack of immunocytochemical analysis of the thyroid and lymph node aspirates, our study should be taken as a preliminary one.

Abstract
Chemokines are a group of small proteins that recruit different leukocyte subtypes to sites of inflammation and play important roles in initiating and maintaining immunological responses in autoimmune endocrine diseases including Graves' disease (GD) and Hashimoto's thyroiditis (HT). Previous studies have found increased gene and protein expression of different kinds of chemokines not only within the thyroid gland but also within thyroid cells in GD or HT patients. A few studies have determined serum levels of chemokines, with conflicting results. We measured circulating concentrations of CCL2, CCL5, CXCL9, and CXCL10 in patients with GD, HT, and nontoxic nodular thyroid disease (NNT). While CCL2 and CXCL9 concentrations were comparable in patients with either AITD or NNT, CCL5 was significantly increased in GD patients compared with HT or NNT subjects. In contrast, CXCL10 levels were lower in patients with GD, but the difference was statistically significant only when compared with patients with HT (p=0.0018). Importantly, GD patients who relapsed or went into remission had significantly different levels of CXCL9 (p=0.0252). Serum levels of CCL2, CCL5, CXCL9, and CXCL10 did not reveal any correlation with thyroid volume; with the levels of thyrotropin (TSH), FT3, or FT4; or with the titers of TSH receptor antibody and thyroperoxidase antibody. These data suggest that the expression patterns of chemokines in various thyroid diseases differ from each other, which may reflect the distinct immune responses in HT and GD.

Abstract
BACKGROUND The relationship between thyroid autoimmunity and cancer is still uncertain. PATIENTS We approached this issue in 570 consecutive patients submitted to thyroidectomy for an indeterminate nodule on cytology. Thyroid autoimmunity was defined as positivity of circulating thyroid autoantibodies (TAb), autoimmune hypo- or hyperthyroidism, thyroid hypoechogenicity on ultrasound, and lymphocytic infiltration on histology. RESULTS TAb were found in 122/570 (21.4%), hypoechogenicity in 115/570 (20.1%), and lymphocytic infiltration in 117/570 (20.5%) of patients. The three features of thyroid autoimmunity were highly concordant: hypoechogenicity was observed in 71/448 (15.8%) patients with negative TAb and in 44/122 (36%) with positive TAb (P < 0.0001); lymphocytic infiltration was found in 53/448 (11.8%) patients with negative TAb and in 64/122 (52.4%) with positive TAb (P < 0.0001); hypoechogenicity on ultrasound was observed in 73/453 (16.1%) patients without, and in 42/117 (35.9%) with lymphocytic infiltration (P < 0.0001). None of these parameters was associated with malignancy. TAb were found in 32/135 (23.7%) patients with carcinoma and in 90/435 (20.6%) with a benign lesion (P = NS); hypoechogenicity was observed in 26/135 (19.2%) patients with carcinoma and in 89/435 (20.4%) patients with benign lesions (P = NS); lymphocytic infiltration was present in 28/135 (20.7%) patients with carcinoma and in 89/435 (20.4%) with benign lesions (P = NS). The frequency of cancer in 11 patients with clinically overt thyroid autoimmune disease did not differ from that observed in the whole study group. CONCLUSION In this group of patients with indeterminate thyroid nodules at cytology, clinical and pathological criteria of thyroid autoimmunity were strongly concordant and not associated with malignancy.

Abstract
INTRODUCTION The main trends concerning the volume of surgery in benign thyroid disease - thyroidectomy or organ - preserved surgery, performed in detected immunological disorders, are not well motivated. The AIM of this study was to analyze changes in humoral and cellular immunity in diseases before and after surgical treatment as well as to assess the effects of surgical procedure and to precise its volume. PATIENTS AND METHODS Changes in immune reactivity were investigated in 100 patients. They were selected with nodular (adenomatous) hyperplastic parenchymal processes in the thyroid gland, with or without hyperfunction - euthyroid or Basedowificated nodular goitre, solitary toxic adenoma and nodular form of lymphocytic thyroiditis. Serum anti - thyroglobulin and anti - microsomal antibodies were examined in these patients, and in 56 of them immunophenotypic flowcytometric analyses of peripheral lymphocytes was performed. RESULTS Serum antithyroid antibodies gradually decrease in one year after surgery. Pre-surgical changes in lymphocyte subsets number in peripheral blood recovered to great extent. This tendency is best demonstrated in lymphocytic thyreoiditis. DISCUSSION Study on immune parameters can help to evaluate the positive effect of organ - preserved and at the same time - radical surgical treatment. CONCLUSION In immune thyroid disorders the organ - preserved radical resection of thyroid gland leaving normal parenchyma is method of choice compared to thyroidectomy since it allows definite treatment with hormonal compensation.

Abstract
OBJECTIVE Denmark was an area of iodine deficiency, and mandatory iodine fortification of table salt and salt in bread (13 p.p.m. iodine) was initiated in 2000/2001. The Danish investigation on iodine intake and thyroid disease (DanThyr) is the monitoring of the iodine fortification program. DESIGN AND METHODS DanThyr consists of three main parts: a study of population cohorts initialized before (n=4649) and after (n=3570) iodization of salt, a prospective identification of incident cases of overt hyper- and hypothyroidism in a population of around 550,000 people since 1997, and compilation of data from the national registers on the use of thyroid medication, thyroid surgery, and radioiodine therapy. Studies were carried-out in parallel in subcohorts living in areas with differences in iodine content of ground water. RESULTS The study showed profound effects of even small differences in iodine intake level on the prevalence of goiter, nodules, and thyroid dysfunction. Mild and moderate iodine deficiency was associated with a decrease in serum TSH with age. Other environmental factors were also important for goiter development (increase in risk, smoking and pregnancy; decrease in risk, oral contraception and alcohol consumption), and the individual risk depended on the genetic background. Environmental factors had only a minor influence on the prevalence of thyroid autoantibodies in the population. There were more cases of overt hypothyroidism in mild than in moderate iodine deficiency caused by a 53% higher incidence of spontaneous (presumably autoimmune) hypothyroidism. On the other hand, there were 49% more cases of overt hyperthyroidism in the area with moderate iodine deficiency. The cautious iodine fortification program, aiming at an average increase in iodine intake of 50 mug/day has been associated with a 50% increase in incidence of hyperthyroidism in the area with the most severe iodine deficiency. The incidence is expected to decrease in the future, but there may be more cases of Graves' hyperthyroidism in young people. CONCLUSION A number of environmental factors influence the epidemiology of thyroid disorders, and even relatively small abnormalities and differences in the level of iodine intake of a population have profound effects on the occurrence of thyroid abnormalities. Monitoring and adjustment of iodine intake in the population is an important part of preventive medicine.

Abstract
OBJECTIVE We assessed the association between thyroid autoimmunity and thyroid cancer in a retrospective series of unselected thyroid nodules submitted to fine-needle aspiration cytology (FNAC) to avoid the selection bias of surgical series. SUBJECTS AND METHODS Ultrasound (US)-guided FNACs were obtained from 590 unselected consecutive patients with single thyroid nodules and positive (ATA + , n = 197) or negative (ATA - , n = 393) serum anti-thyroid antibody (ATA). Cytological results were classified in three classes of increased risk of malignancy: low risk or benign (class II); indeterminate risk (class III); and suspect or malignant (class IV). RESULTS A higher prevalence of class III (28.9% vs 21.4%, P < 0.05) and class IV (18.8% vs 9.2%, P < 0.001) and lower prevalence of class II (52.3% vs 69.5%, P < 0.001) were found in ATA + vs ATA - nodules respectively. By multivariate logistic regression analysis ATA + conferred a significant risk (odds ratio (OR): 2.29 (95% confidence interval (CI): 1.39-3.76)) for class IV cytology independently from age and sex. In 106 patients where thyroidectomy was carried out, thyroid cancer was found in 54/61 (88.5%) patients with class IV nodules (with similar positive predictive value for cancer in ATA + (96.4%) and ATA- (81.8%) nodules), in 6/31 (19.3%) of class III nodules (all ATA - ) and in none of 14 class II nodules. Non-specific cytological atypias from hyperplastic nodules in lymphocytic thyroiditis probably accounted for the different prevalence of cancer in class III ATA + and ATA - nodules. Histologically proven thyroid cancer (mostly papillary) was then observed in a higher proportion (27/197 = 13.7%) of ATA + , when compared with ATA - nodules (33/393 = 8.4%, P = 0.044), but the significance of this finding is limited by the low number of class II nodules operated on. CONCLUSIONS The presence of ATA + confers an increased risk of suspicious or malignant cytology in unselected thyroid nodules. Since ATA + is not responsible for increased false-positive class IV FNAC, our study provides indirect evidence supporting a significant association between thyroid carcinoma and thyroid autoimmunity, although further studies with a different design are needed for a definitive histological proof.

Abstract
OBJECTIVE Treatment of benign thyroid tumors with percutaneous ethanol injections (PEI) is an alternative to radioiodine and surgery. This procedure causes a release of large amounts of denaturated thyroglobulin within the gland which may become an autoantigen, triggering the mechanism of autoimmunization. The aim of the study was to investigate whether ethanol injections can induce increased levels of thyroid autoantibodies and tumor necrosis factor-alpha (TNF-alpha) in patients with nonfunctioning or pre-toxic thyroid nodules. MATERIAL AND METHODS Thirty-four patients (31 F, 3 M) with single benign thyroid tumors were enrolled, 23 (20 F/3 M) with nonfunctioning nodule (group 1) and 11 (F) with pre-toxic nodule characterized by normal free thyroid hormones and low TSH (group 2). Under sonographic guidance, sterile 96% ethanol solution was injected into thyroid nodules at 2-week intervals up to a dose of 0.7-1.0 ml of ethanol per 1.0 ml nodule volume. TSH, fT4, thyroglobulin antibodies and thyroperoxidase antibodies as well as TNF-apha levels were assessed prior to alcohol administration and 3, 6, and 12 months after the end of treatment. RESULTS PEI treatment decreased tumor volume by 75.8% in group 1 and by 80.4% in group 2, and normalized TSH level in 90.9% of patients with pre-toxic nodules. No statistically significant differences in thyroperoxidase antibodies and TNF-alpha levels were observed during the study period in both groups. Thyroglobulin antibody levels increased significantly 6 months after treatment in both groups, but returned to the baseline levels after 12 months. No significant difference in peak thyroglobulin antibody levels between the two groups was seen. CONCLUSION PEI procedure is a safe method for treating nonfunctioning and pre-toxic thyroid nodules since this treatment reduces tumor size significantly without inducing long-lasting autoimmune reactions in the thyroid gland. Transient increase in thyroglobulin antibodies indicates that this procedure should be performed with caution in patients at risk of autoimmune diseases.

Abstract
Why does cancer develop? What is the essence of premalignant lesions? My answer to these sacramental questions follows. I found out that hyperplastic and tumor nodules are immunologically privileged sites, like the anterior chamber of the eye or the hamster's retrobuccal sac. The antigens from the nodules do not provoke the body's immune reactions, unlike the same antigens from the extranodular tissue. On the other hand, both the autoantibodies and the killer-cells sensitized to this antigens are unable to react with that part of the cells possessing antigens, which are situated within the nodules and completely destroy the same cells in the extranodular tissue. Hyperplastic and tumor nodules are special sites where immunological surveillance is absent. It is because they have no lymphatic and so recirculation of immunocompetent cells through its territory is impossible. Thus, newborn malignant cells in these precancerous formations avoid the immunological control and survive, in contrast to the tissue with the normal structure. So, neoplastic processes will be free from immunological surveillance in the precancerous sites and will therefore be more likely to progress.

Abstract
Our aim was to investigate the occurrence of clinical and subclinical autoimmune thyroid disease in 79 patients with celiac disease as reflected in thyroid function, antibodies, and ultrasound. Since subclinical thyroid diseases are common in the population, 184 nonceliac controls were also studied. Normal thyroid function combined with positive antibodies and marked hypoechogenicity was considered subclinical disease. Autoimmune thyroid disease was observed in 13.9% of celiac patients and in 2.1% of controls (P = 0.0005); and subclinical disease in 10.1% and 3.3%, respectively (P = 0.048). The mean thyroid gland volume was 8.3 ml in celiac patients and 10.4 ml in controls (P = 0.007). Hypoechogenicity was found in 73% of celiac patients and in 42% of controls (P < 0.0001). Positive thyroid antibodies were associated with hypoechogenicity in celiac patients but not in controls. In conclusion, the occurrence of both clinical and subclinical autoimmune thyroid disease was increased in celiac disease; subclinical thyroid disease indicates regular surveillance.

Abstract
INTRODUCTION The chance of malignancy in scintigraphically cold thyroid nodules is 2-24%. Differentiation between malignant and benign cytology is difficult. The aim of this study was to evaluate the ability of immunostaining (MoAB47--raised against thyroid peroxidase (TPO)) to differentiate between malignant and benign cells taken from cold thyroid nodules by fine needle aspiration biopsy (FNAB) in order to reduce the number of unnecessary thyroid operations. MATERIALS AND METHODS One hundred and eighty-one patients (150 female) with a scintigraphically cold, solitary thyroid nodule were entered between 1993 and 1996. Fifty-seven were excluded for various reasons. Material removed by FNAB was stained with MoAB47 and routine staining. Staining of 80% or more of the cells was considered benign, less than 80% was considered malignant. Routine staining of operatively removed material was used as the final diagnosis. RESULTS A pattern with negative TPO staining was found in all lesions that were subsequently proved to be malignant. In all but one, the lesions subsequently diagnosed as being benign stained positive for TPO. The sensitivity and specificity were respectively 1.0 and 0.99. CONCLUSION TPO immunostaining of material removed by FNAB is a powerful tool in the differentiation between benign and malignant tumours.

Abstract
Prolactin (PRL) possesses mitogenic and immunomodulatory properties. We evaluated the prevalence of ultrasonographic thyroid alterations and thyroid autoimmunity in hyperprolactinaemic (HPRL) women and correlated these with PRL levels. Furthermore, we studied the PRL binding in human benign nodular thyroid tissues. 133 HPRL patients (16-63 years) and 103 healthy female controls (16-63 years) with no known history of thyroid disease were studied. Blood samples were collected for PRL, FT3, FT4, TSH, thyroid peroxidase auto-antibodies (TPO Ab) and thyroglobulin auto-antibodies (Tg Ab) assays. All subjects underwent thyroid ultrasonography. PRL binding to thyroid membranes was determined by in-vitro radioreceptor assay in 5 human benign nodular thyroid fragments obtained from female patients. No difference in TSH levels was found, while FT3 (4.5 +/- 0.1 pmol/L) and FT4 (16.2 +/- 0.4 pmol/L) levels were significantly higher in controls than in HPRL (FT3: 3.8 +/- 0.1 pmol/L, p = 0.01, FT4: 15.4 +/- 0.2 pmol/L, p = 0.04). The prevalence of thyroid ultrasonographic alterations (simple goitre, uni-multinodular goitre, chronic thyroiditis) was significantly higher in HPRL (30.8%) than in controls (15.5%, p = 0.01) but did not correlate with mean initial and actual PRL levels or duration of the disease. The prevalence of autoantibodies was significantly higher in HPRL (29.6%) than in controls (14.3%, p = 0.04) but did not correlate with PRL levels. Very low specific PRL binding to thyroid membranes was detected. The high prevalence of thyroid ultrasonographic alterations and autoimmunity in HPRL suggests a possible role of PRL in the development of thyroid diseases. Clinical and instrumental thyroid screening may therefore be advisable in these patients.

Abstract
OBJECTIVE To determine the value of cytomorphologic features and argyrophilic nucleolar organizer regions in fine needle aspiration smears of thyroid nodules. STUDY DESIGN Cytomorphologic features were analyzed for frequency and predictive value in smears of 60 histologically confirmed cases of thyroid nodules, comprising 16 cases of papillary carcinoma, 19 of follicular adenoma, 5 of follicular carcinoma, 3 or medullary carcinoma and 17 of adenomatous goiter. The smears were also stained for AgNORs to compare AgNOR counts in these lesions. RESULTS Intact follicles and abundant background colloid were useful for the diagnosis of adenomatous goiter; metaplastic cells, nuclear grooves and multinucleate giant cells predicted the diagnosis of papillary carcinoma; and acinar formations were important in the diagnosis of follicular adenoma and follicular carcinoma. AgNOR counts showed major overlaps among the various groups, although the mean counts in neoplastic lesions were slightly higher than those in adenomatous goiter CONCLUSION AgNOR counts failed to have any significant diagnostic utility, and the fine needle aspiration cytology diagnosis of thyroid nodules must still be based on a combination of cytologic features.

Abstract
The incidence of autoimmune disease of the thyroid approaches 10% in women. This autoimmune state, which predisposes to the development of thyroid neoplasia, especially in patients with subclinical hypothyroidism, combined with tumor growth and immunologic factors that occur in the pregnant state, account for the significant incidence of nodular thyroid disease in pregnancy. Thyroid carcinoma of follicular cell origin in a young woman can generally be expected to pursue a slow course with ample time for preoperative preparation and operative treatment. However, the pregnant state should be considered an exception and thyroid nodular disease with suspicious aspiration cytologic features should be managed with a certain degree of urgency. In an excellent article on the subject of pregnancy as a predisposing factor in thyroid neoplasia, Rosen and Walfish present a series of 30 patients with thyroid neoplasia arising during pregnancy. The incidence of thyroid carcinoma was 43% and the incidence of adenoma 37%, for an 80% overall incidence of neoplasia. Furthermore, during the course of the pregnancy, 20% of the patients showed marked increase in nodular growth, including a 26-year-old primiparous woman who developed a small nodule in the first trimester which proved to be cellular on needle aspiration biopsy. In spite of thyroid hormone treatment, the nodule grew markedly in the last trimester. At postpartum operation, the patient was found to have a papillary carcinoma with extensive unilateral neck and mediastinal node disease, which was clinically occult. These authors stress the importance of the operative treatment of thyroid neoplasia of pregnancy, either in the second trimester or immediately after delivery. We agree.

Abstract
The authors investigated the value of percutaneous ethanol injection in the treatment of Plummer's adenoma. Ten patients were studied: they exhibited a single, hot and toxic nodule in the thyroid. Thyroid autoimmunization (TSAb; TMAb; TGAb) and function (T3; T4; TSH; FT3; FT4) were studied in all patients, before treatment and at 1 month and 3 months. Scintigraphy with 99Tc was performed at the same time intervals. In the euthyroid stage, alcoholization was preceded by US and cytology. Three-four ml of ethanol 95 degrees were injected once or twice a week, from a minimum of 3 to a maximum of 8 injections. Treatment was successful in 2 cases; partial success was obtained in 4 cases, and in 4 cases treatment failed. In all successful cases antibodies were negative and the nodules had hypoechoic echostructure, with a peripheral hypoechoic halo and no areas of internal colliquation. Thus, US-guided percutaneous alcoholization seems to be capable of correct indications in hypoechoic nodules not exhibiting areas of colliquative necrosis and with negative antibodies. However, the problem of the dose of alcohol to inject to treat the nodule thoroughly is still to be debated.
