Increased levels of TC and LDL-C were found in patients infected with H. pylori, and updated Sydney System score showed a positive correlation with LDL-C and TC levels. These findings may explain why H. pylori infection is associated with increased risk of atherosclerosis.

IL-33 is a proinflammatory cytokine that is a member of IL-1 family. Previously the effect of IL-33 on kidney injury is showed in animal models. In this study, we searched if we can use IL-33 to show the early stage of kidney injury in diabetic patients. Three groups are identified: 26 patients in Group 1: Healthy group, that do not have any chronic diseases and not taking any medication; 42 patients in Group 2: DM (diabetes mellitus) group without any known kidney disease and with normal kidney functions; 32 patients in Group 3: DM þ MA (microalbuminuria) group that are assumed to have nephropathy. IL-33 level of DM patient group is greater than healthy group; also IL-33 level of DM þ MA patient group is greater than healthy group; but there is not any difference between DM and DM þ MA group. The increase in IL-33 levels in diabetic nephropathy is not associated with kidney injury but the increase could be resulting because of diabetes. So IL-33 cannot be used in early recognition of diabetic nephropathy.

Objective: To establish whether there is a relationship between hyperprolactinemia and primary thyroid disorders, focusing on patients with autoimmune features. Materials and methods: The medical records of 100 patients with hyperprolactinemia (HPRL) were retrospectively examined. Records of thyroid ultrasonography (USG), basal serum levels of thyroid stimulating hormone, circulating free thyroxine, free triiodothyronine, antithyroglobulin (anti-Tg), and antithyroperoxidase (anti-TPO) antibodies were analyzed. In 100 control subjects, matched by age and gender with HPRL patients, thyroid USG, thyroid function tests (TFTs), and autoantibody panel were obtained. Results:The median PRL in patients was 93 ng/mL (range: 37-470). Twenty-five patients (25%) and 22 controls (22%) had positive anti-Tg and/or anti-TPO titers (P = 0.739). The median serum PRL was 98 (37-470) ng/mL in patients with positive thyroid autoantibodies, and 92 (40-470) ng/mL in patients who were negative (P = 0.975). Among the individuals with autoantibody positivity TFTs abnormalities were more frequent in HPRL patients (60%, out of 25 patients, 14 with subclinical hypothyroidism and one with hyperthyroidism) than in controls (9.1%, out of 22 patients, 2 with subclinical hyperthyroidism) (P < 0.001). Twenty-seven patients with HPRL and 31 controls had goiter (27 vs. 31%, P = 0.437). Fortysix patients (46%) and 50 (50%) controls had one or more of the features of thyroid disorder, which were goiter, positive thyroid autoantibody, and thyroid function abnormality (P = 0.888). Conclusion:HPRL may be associated with more severe thyroid dysfunction in patients with thyroid autoimmunity.Arq Bras Endocrinol Metab. 2014;58(1):48-52 Keywords Hyperprolactinemia; thyroiditis; autoimmunity; goiter RESUMO Objetivo: Verificar se existe uma relação entre a hiperprolactinemia e distúrbios primários da tireoide, focando em pacientes com características autoimunes. Materiais e métodos: Os prontuários de 100 pacientes com hiperprolactinemia (HPRL) foram examinados retrospectivamente. Foram analisados registros de ultrassonografia da tireoide (USG), níveis séricos basais de hormônio tireoestimulante, tiroxina livre, triiodotironina livre e anticorpos antitireoglobulina (anti-Tg) e antitireoperoxidase (anti-TPO). Foram obtidos de 100 controles, pareados por idade e sexo com pacientes com HPRL, USG, testes de função da tireoide (TFTs) e painel de autoanticorpos. Resultados: A média de PRL em pacientes foi de 93 ng/mL (variação: 37-470). Vinte e cinco pacientes (25%) e 22 controles (22%) foram positivos para títulos de anti-Tg e/ou anti-TPO (P = 0,739). A mediana de PRL sérica foi de 98 (37-470) ng/mL em pacientes positivos para autoanticorpos tiroidianos e 92 (40-470) ng/mL em pacientes negativos (P = 0,975). Entre os indivíduos positivos para autoanticorpos, as anormalidades da TFTs foram mais frequentes em pacientes HPRL (60%; de 25 pacientes, 14 com hipotireoidismo subclínico e um com hipertireoidismo) do que nos controles (9,1%; de 22 pacientes, 2 com hip...

Objectives: To compare B-type natriuretic peptide (BNP) and echocardiographic parameters in patients with hepatitis B virus (HBV) and healthy control subjects. Subjects and Methods: 52 consecutive patients with HBV and 47 healthy controls were examined. All subjects underwent transthoracic echocardiography after a complete medical history and laboratory examination including BNP, C-reactive protein (CRP) and high-sensitivity CRP (hsCRP). Results: Demographic characteristics were similar in patients with HBV and the control group. No significant difference was found in conventional Doppler and tissue Doppler parameters between the two groups. BNP levels were significantly higher in patients with HBV [6.5 ng/l (range 0.5-85.2)] than controls [4.3 ng/l (range 0.5-18.3)], p = 0.039. hsCRP [3.25 mg/l (0.02-40.2) vs. 0.5 mg/l (0.02-8.0)] levels were significantly higher in patients with HBV than control subjects (p < 0.001). Conclusion: Patients with HBV had higher BNP, CRP, and hsCRP levels than controls. Echocardiographic findings were similar in both groups. This slight BNP elevation in HBV patients may be related to chronic inflammation due to HBV.

For detection of malignant lymph nodes, determining ratios of nonaspiration FNB-Tg to whole blood and/or serum washout-Tg might be a promising method to increase accuracy and provide standardization of lymph node washout procedure.
