Clinical and laboratory characteristics of patients with thyroid diseases with and without alanine aminotransferase levels above the upper tertile – Cross-sectional analytical study

Objective Thyroid disease affects 6.6% of the general population. The liver is fundamental in metabolizing thyroid hormones, and hepatocytes are often affected in thyroid disease. We aimed to compare clinical and laboratory parameters among thyroid disease patients with alanine aminotransferase (ALT) levels above vs. below the upper tertile. Subjects and methods A retrospective cross-sectional analytical study was conducted in the endocrinology clinic at Polydoro Ernani de São Thiago University Hospital. Patients with thyroid disease between August 2012 and January 2014 were included in the study. Clinical and laboratory parameters were collected from medical records. Results One hundred patients were included, of which 14.0% were male, with a mean age of 49.1 ± 14.4 years. ALT levels ranged from 9 to 90 U/L, and the ALT upper tertile was defined as 0,64 times the upper normal limit (xUNL). Patients with ALT levels above the upper tertile exhibited a higher proportion of systemic arterial hypertension (SAH), a higher mean abdominal circumference and a higher frequency of elevated TSH levels than did patients with ALT levels below the upper tertile. In multivariate analysis, ALT ≥ 0.64 (xUNL) was independently associated with abdominal circumference (odds ratio [OR] = 0.087, 95% confidence interval [CI] 0012-0167, P = 0.022). ALT (xUNL) correlated positively with total cholesterol (r = 0.213, P = 0.042). Conclusions In patients with thyroid diseases, it was observed that those with ALT above the upper tertile are associated with abdominal circumference and ALT levels correlate with total cholesterol.

Relação dos níveis do hormônio estimulante da tireóide (TSH) com a maliginidade dos nódulos de tireóide / Association between elevated levels of TSH and higher prevalence of thyroid cancer has been reported

Introdução: associação entre os níveis elevados de TSH como fator trófico á célula tireoidiana e a maior prevalência de câncer tireoidiano tem sido discutida. Objetivos: Relacionar os Níveis de TSH em Valores de Corte, conforme a literatura, com a malignidade em nódulos de tireóide (NT). Material e métodos: Estudo tranversal de 159 prontuários ( 171NT) no HU/UFSC de agosto de 2010- 2012. Realizadas avaliações cito-patológicas e do TSH em ensaio de quimiluminescência( terceira geração) á época da punção aspirativa e categorizando os pontos de corte. Pacientes com disfunçaõ estabelecida foram excluídos. Análises estatistícas com teste do X2 e Fischer e significância em p< 0,05. Resultados: A média de idade dos pacientes foi de 48 anos com 92,4% de mulheres; 2,9% , 64,3% , 5,3%, 10,5%, 8,8% e 8,2% dos NT com Bethesda 1a VI respectivamente. O TSH variou de 0,08 a 10,5 ( média: 1,965 ± 1,69; mediana: 1,48) uUI/mL. Trinta e cindo NT foram operados, sendo 74,3% malignos e, deses, 80,8% carcinomas papilíferos. Análises dos grupamentos Bethesda e citopatológicos ( casos operados + não operados com citopatologias II, V, VI = 150 NT) em valores de corte de TSH< 1 e ≥ 1, TSH < 1,8 e ≥ 1,8 uUI/mL .Evidenciaram significância apenas em 1,8, com 32,7% dos NT Bethesda II e 71,4 % dos Bethesda VI ≥ 1,8 . Confirmando-se a Histopatologia onde 33,9%de 115 NT Benignos versus 60% de 35 NT Malignos apresentavam TSH≥ 1,8 uUI/mL(p<0,006).

Background: Association between elevated levels of TSH and higher prevalence of thyroid cancer has been reported. Objectives: To relate TSH levels with malignancy in thyroid nodules (TN). Methods: A transversal study of 159 medical records (171NT) in HU / UFSC August 2010-2012. Performed cyto-pathological and TSH reviews in chemiluminescence assay (third generation) will time of aspiration and categorizing the cutoffs. Patients with established dysfunction were excluded. Statistical analysis with X2 test or Fisher and significance was p <0.05. Results: Total 159 patients (171 TN). Average age: 48 years; women: 92.4%; TSH: 0.08 to 10.5 (mean: 1.965, median: 1.48) uUI / mL and 2.9%, 64.3%, 5.3%, 10.5%, 8.8% and 8.2% of the 171 TN with Bethesda I to VI, respectively. Thirty-five TN operated, being 74.3% malignant and, of these, 80.8% papillary carcinomas. Analyses in groups of Bethesda (171 TN) and cyto-pathological (150 TN) on TSH cutoffs of <1, ≥ 1, <1.8 and ≥ 1.8 uUI / mL showed significance on higher cutoffs (1.8) in the various groups of Bethesda, confirming the cyto-histopathology in 33.9% of 115 benign TN vs 60.0% of 35 malignant ≥ 1.8 uUI / mL (p = 0.006). Conclusion: Malignancy in NT was related to valro cutting TSH ≥ 1.8 UUI / mL.

Prevalence and clinical features of celiac disease in patients with autoimmune thyroiditis: cross-sectional study / Prevalência e características clínicas da doença celíaca em pacientes com tireoidite autoimune: estudo transversal

CONTEXT AND OBJECTIVE: Celiac disease is an autoimmune disorder with an average prevalence of 1% in Europe and the United States. Because of strong European ancestry in southern Brazil, this study aimed to evaluate the seroprevalence of celiac disease among autoimmune thyroiditis patients. DESIGN AND SETTING: Cross-sectional study in a public university hospital. METHODS: This cross-sectional prevalence study included autoimmune thyroiditis patients who were tested for anti-endomysial and anti-transglutaminase antibodies between August 2010 and July 2011. RESULTS: Fifty-three patients with autoimmune thyroiditis were included; 92.5% were women, with mean age of 49.0 ± 13.5 years. Five patients (9.3%) were serologically positive for celiac disease: three of them (5.6%) were reactive for anti-endomysial antibodies and two (3.7%) for anti-transglutaminase. None of them exhibited anemia and one presented diarrhea. Endoscopy was performed on two patients: one with normal histology and the other with lymphocytic infiltrate and villous atrophy. CONCLUSION: The prevalence of celiac disease among patients with autoimmune thyroid disease was 9.3%; one patient complained of diarrhea and none presented anemia. Among at-risk populations, like autoimmune thyroiditis patients, the presence of diarrhea or anemia should not be used as a criterion for indicating celiac disease investigation. This must be done for all autoimmune thyroiditis patients because of its high prevalence. .

CONTEXTO E OBJETIVO: A doença celíaca é uma doença autoimune, com prevalência média de 1% na Europa e nos Estados Unidos. Em função da forte ascendência europeia no sul do Brasil, este estudo objetiva relatar a soroprevalência de doença celíaca em indivíduos com tireoidite autoimune. TIPO DE ESTUDO E LOCAL: Estudo transversal em um hospital público universitário. MÉTODOS: Este estudo transversal de prevalência incluiu pacientes com tireoidite autoimune que foram submetidos a testes de anticorpos antiendomísio e antitransglutaminase entre agosto de 2010 e julho de 2011. RESULTADOS: Foram incluídos 53 pacientes com tireoidite autoimune, 92,5% mulheres, com idade média de 49,0 ± 13,5 anos. Cinco (9,3%) pacientes apresentaram sorologia positiva para doença celíaca, sendo três (5,6%) com anticorpo antiendomísio positivo e dois (3,7%) com antitransglutaminase positivo. Nenhum paciente apresentou anemia e um apresentou diarreia. Apenas dois pacientes realizaram endoscopia: um com histologia normal e outro apresentou infiltrado linfocitário e atrofia vilositária. CONCLUSÕES: A prevalência de doença celíaca entre pacientes com doença autoimune da tireoide foi de 9,3%; um paciente queixou-se de diarreia e ninguém apresentou anemia. Em populações de risco, como é o caso de pacientes com tireoidite autoimune, a presença de diarreia ou anemia não devem ser utilizados como critério para indicar investigação de doença celíaca, que deve ser feita em todos os indivíduos com tireoidite autoimune devido a sua alta prevalência. .
