LOW BONE MINERAL DENSITY IN BRAZILIAN PATIENTS AT DIAGNOSIS OF CELIAC DISEASE

BackgroundLow bone mineral density is considered an extra-intestinal manifestation of celiac disease with reduced bone mass, increased bone fragility, and risk of fractures. Celiac disease is considered a condition at high risk for secondary osteoporosis and the evaluation of bone density is very important in the clinical management of these patients.ObjectiveThe present study aimed to investigate bone alterations in celiac patients from Curitiba, South Region of Brazil at diagnosis, correlating the findings with age and gender.MethodsPatients who were included in the study were attended to in a private office of the same physician from January 2009 to December 2013. The diagnosis of celiac disease was done through clinical, serological and histological findings. All data were collected from the medical charts of the patients. After the diagnosis of celiac disease, evaluation for low bone mineral density was requested by dual-energy X-ray absorptiometry (DEXA). DEXA bone densitometer was used to estimate low bone mineral density at the lumbar spine and femur.ResultsA total of 101 patients, 82 (81.2%) female and 19 (18.8%) male subjects, with mean age of 39.0±3.03 years were included. At celiac disease diagnosis, 36 (35.6%) were younger than 30 years, 41 (40.6%) were between 31 and 50 years, and 24 (23.8%) were older than 50 years. Among the evaluated patients, 69 (68.3%) presented low bone mineral density, being 47% with osteopenia and 32% with osteoporosis. Patients who were older than 51 years and diagnosed with celiac disease presented low bone mineral density in 83.3% (20/24) of the cases. As expected, age influenced significantly the low bone mineral density findings. Among women, low bone mineral density was present with high frequency (60%) from 30 to 50 years. In patients diagnosed older than 60 years (n=8), all the women (n=5) and two of the three men had osteoporosis.ConclusionThis study demonstrated that 69% of Brazilian patients with celiac disease at diagnosis had low bone mineral density, being more frequent in women older than 50 years

Alterações do TSH em pacientes com síndrome de Down: uma interpretação nem sempre fácil Alterations of TSH in Down's syndrome patients: a hard interpretation

OBJETIVO: Determinar as concentrações de hormônio estimulante da tireóide (TSH) e a presença de anticorpos antitireoperoxidase (anti-TPO) em pacientes com síndrome de Down (SD) atendidos no ambulatório do Hospital de Clínicas da Universidade Federal do Paraná. MÉTODOS: Foram incluídos no estudo 72 pacientes com SD, não aparentados e selecionados consecutivamente, com média de idade de 6,15 anos. Oitenta crianças sadias, pareadas com os pacientes, foram utilizadas como controles. Em todas as amostras foram determinadas as concentrações séricas de TSH e de anti-TPO, através do método de dosagem imunométrica. RESULTADOS: Trinta pacientes com SD (42,9%) apresentaram alterações nas concentrações de TSH, sendo que 4,3% tinham valores menores que 0,5µUI/ml e 38,6%, valores superiores a 5µUI/ml (5,1 a 22) (média de 5,56 ± 4,18µUI/ml). Nos controles, a concentração média de TSH foi 2,76µUI/ml (± 1,14), evidenciando-se um aumento significativo nos níveis de TSH nos pacientes com SD (p < 0,001). De forma similar, caracterizou-se uma diferença significativa na positividade para o anti-TPO nos pacientes (15,4%) em relação aos controles (0%; p < 0,001). Observou-se ainda aumento significativo nas concentrações de TSH nos pacientes com idade superior a 9 anos (média de 6,86 ± 4,6µUI/ml) quando comparados aos menores de 9 anos (média de 5,24 ± 3,81µUI/ml; p = 0,006), bem como na positividade do anti-TPO (6/20 vs. 5/52; p = 0,041). CONCLUSÕES: Os resultados demonstraram alta prevalência de alterações das dosagens de TSH e de doença tireoidiana nos pacientes com SD, principalmente naqueles com idade superior a 9 anos. Os dados indicam que a avaliação da função tireoidiana nos pacientes com SD deve receber atenção especial dos profissionais de saúde que atendem esses pacientes.<br>OBJECTIVE: To evaluate the thyroid stimulating hormone (TSH) levels and the presence of antithyroperoxidase antibody (anti-TPO) in Down’s syndrome (DS) patients from Hospital de Clínicas of Universidade Federal do Paraná (HC/UFPR). METHODS: Seventy-two DS patients, non-related and consecutively selected (mean age 6.15) were included in the study. Eighty matched healthy children were used as controls. The TSH measurement and the anti-TPO were determined by immunometric assay in all samples. RESULTS: Thirty patients with DS (42.9%) presented abnormal levels of TSH; 4.3% showed values below 0.5µIU/ml and 38.6% presented values higher than 5µIU/ml (range 5.1-22; mean 5.56 ± 4.18µIU/ml). The mean concentration of TSH in the controls was 2.76 ± 1.14µIU/ml, indicating a significant increase in TSH levels in the DS patients (p < 0.001). Similarly, a significant difference was observed in the anti-TPO positivity in the patients’ group (15.4%) when compared with the controls (0%; p < 0.001). In addition, the TSH levels of patients older than 9 years presented a significant increase (mean of 6.86 ± 4.6µIU/ml) when compared with the levels observed in patients younger than 9 years (mean of 5.24 ± 3.81µIU/ml; p = 0.006). The same pattern was observed in the positivity of anti-TPO (6/20 vs. 5/52; p = 0.041). CONCLUSIONS: The results demonstrated high prevalence of elevated TSH and anti-TPO in the patients from the DS ambulatory of HC/UFPR, with increased frequency in those older than 9 years. The data indicate that the evaluation of thyroid function in DS patients must receive special attention from health professionals who take care of these patients

QUALITY OF LIFE EVALUATION IN CELIAC PATIENTS FROM SOUTHERN BRAZIL

BackgroundRestrictions imposed by the gluten-free diet generate large changes in the daily habits of the celiac patient, causing a negative impact on quality of life.ObjetiveThis study aimed to evaluate the quality of life of patients with celiac disease on a capital in Southern Brazil.MethodsPatients older than 18 years were included, with confirmed celiac disease for at least 60 days in the period from June to October 2013. A validated questionnaire, with specific questions to assess the patient&#8217;s quality of life celiac was applied. A total score ranged from 20 to 100 points; the higher the score, worse quality of life.ResultsA total of 103 questionnaires were evaluated, 96 (93.2%) female, with average score 56.6±12.35 (28 to 88 points). The comparison between the questionnaire scores and family income was not significant (P=0.139). Patients diagnosed less than 1 year have poorer quality of life than those with more than 10 years (P=0.063). Patients older than 60 years had better quality of life compared with the younger ones (P=0.04).ConclusionThere was no association between quality of life and factors such as family income, length of diet and age at diagnosis. Chronological age greater than 60 years has positively influenced the quality of life of celiac patients
