Thymic Neuroendocrine Tumor Presenting as Cushing’s Syndrome

Krausova Adela , Limanova Zdenka , Sedlačkova Eva , Schutzner Jan , Michalsky David , Hana Vaclav , Jiskra Jan

Introduction: Cushing’s syndrome (CS) is a rare disease with incidence estimated 2-4 cases per million inhabitants per year. ACTH-dependent forms comprise up to 80% of all cases, of which 80% are central and 20% are ectopic, paraneoplastic forms of ACTH-dependent CS. Thymic neuroendocrine tumors (NET) are accounting for 0,4 - 3% of all NET’s with incidence of 0.02/100 000 inhabitants/year. Up to one third of them are hormonally active (secrete adrenocorticotropic hor...

Anti-C1q autoantibodies are linked to autoimmune thyroid disorders in pregnant women.

Vitkova Hana , Jiskra Jan , Springer Drahomira , Limanova Zdenka , Telicka Zdenek , Bartakova Jana , Potlukova Eliska

Introduction: Anti-C1q antibodies have been implicated in the pathogenesis of systemic lupus erythematosus. We have previously shown that anti-C1q antibodies are also linked to autoimmune thyroid disorders (AITD). The aim of this study was to assess the occurrence of anti-C1q antibodies in pregnant women with AITD.Methods: Serum anti-C1q antibodies were measured during the 9–11th gestational weeks in 103 pregnant women screened positive for AITD, an...

Latent toxoplasmosis: a novel risk factor for autoimmune thyroid diseases in pregnancy?

Potlukova Eliska , Prochazkova Lucie , Jiskra Jan , Limanova Zdenka , Springer Drahomira , Calda Pavel , Flegr Jaroslav , Kankova Sarka

Introduction: Latent toxoplasmosis, a zoonosis caused by protozoan Toxoplasma gondii, is the most widespread human parasitosis in developed countries (prevalence 20–80%). Upon infection, T. gondii stays in human organism lifelong. It has been linked to several autoimmune diseases, including autoimmune thyroid disease (AITD). The aim of our study was to assess the impact of latent T. gondii infection on the prevalence of AITD in pregnancy with re...

Iodine status in women after early miscarriages in the Czech Republic

Jiskra Jan , Fait Tomas , Bilek Radovan , Bartakova Jana , Potlukova Eliska , Springer Drahomira , Telicka Zdenek , Limanova Zdenka

Background: Early miscarriages are of multifactorial origin. Subclinical thyroid dysfunction belongs to the common causes. Thyroid dysfunction in pregnancy is caused mainly by thyroid autoimmunity and/or iodine deficiency. The Czech Republic belongs to countries with sufficient iodine intake. The aim of the study was to determine iodine status in women after early miscarriages (n=183) and to compare it with randomly chosen age-comparable euthyroid women without previo...

Is age a risk factor for hypothyroidism in pregnancy? An analysis of 5223 pregnant women

Potlukova E. , Potluka O. , Jiskra J. , Limanova Z. , Telicka Z. , Bartakova J. , Springer D.

Introduction: The guidelines of American Thyroid Association from 2011 include age over 30 as one of the risk factors for hypothyroidism in pregnancy. The aim of our study was to verify whether age increases the risk of autoimmune thyroid diseases (AITD) in pregnant women.Methods: We performed a cross-sectional study in 5223 unselected consecutive pregnant women in the 9th–12th gestational weeks. In a single laboratory, we measured serum concentrati...

Postpartum follow-up of women positively screened for thyroid disease in pregnancy: the necessity of a better care

Potlukova E , Jiskra J , Telicka Z , Bartakova J , Springer D , Limanova Z

Introduction: The utility of screening for antibodies against thyroperoxidase (TPOAb) in early pregnancy remains controversial. The aim of our retrospective follow-up study was to examine the thyroid function of initially euthyroid TPOAb+ women at a longer period after delivery.Methods: We invited 822 women screened positive for thyroid disorders in the first trimester of pregnancy (9th–12th gestational week) for follow-up. This included measurement...

Serum levels of antibodies to thyroid peroxidase in women after miscarriages in comparison with the 1st trimester of pregnancy and healthy non-pregnant women

Jiskra Jan , Fait Tomas , Limanova Zdenka , Antosova Marie , Telicka Zdenek , Springer Drahomira , Potlukova Eliska

Background: Etiology of infertility and miscarriages is multifactorial. Negative impact of overt thyroid dysfunction on fertility, pregnancy and development of offspring is known. Moreover, even presence of euthyroid autoimmune thyroid diseases may increase risk of miscarriages. The prevalence of positive antibodies to thyroid peroxidase (TPOAb) ranges 9–39% in women with recurrent miscarriages and 0–37% in controls. The aim of the study was to compare serum concentr...

The prevalence of anti-C1q antibodies is increased in autoimmune thyroid disorders

Potlukova Eliska , Jiskra Jan , Sandova Petra , Limanova Zdenka , Smutek Daniel , Mareckova Helena , Antosova Marie , Trendelenburg Marten

Background: Autoantibodies directed against complement C1q (anti-C1q) have been described in a number of systemic autoimmune disorders. In systemic lupus erythematosus, they are strongly associated with proliferative lupus nephritis. However, no study has focused on the presence of anti-C1q in organ specific autoimmune disorders. The aim of this study was to determine the prevalence of anti-C1q in autoimmune thyroid disorders (AITD).Methods: Serum levels...

Soluble interleukin 2 receptor is elevated in sera of women with Graves’ disease and has relation to serum free thyroxin and thyroid volume

Jiskra J , Antosova M , Potlukova E , Lacinova Z , Mareckova H , Sandova P , Smutek D , Limanova Z

Introduction: Although some studies have shown elevated soluble interleukin 2 receptor (sIL-2R) in sera of patients with hematological malignancies and some autoimmune diseases, its role in serum is not fully understood.Patients and methods: The aim was to compare serum levels of sIL-2R in four groups of women (11 with Graves’ disease, 10 with Hashimoto’s thyroiditis, 11 with breast cancer and 10 healthy controls) and to test their possible rel...

Thyroid hormones regulate the production of complement mannan-binding lectin regardless of the MBL2 genotype: a cohort study of 95 patients with autoimmune thyroid disorders.

Potlukova Eliska , Jiskra Jan , Freiberger Tomas , Limanova Zdenka , Zivorova Dana , Malickova Karin , Springer Drahomira , Grodecka Lucie , Antosova Marie , Telicka Zdenek , Pesickova Sattu Sinikka , Trendelenburg Marten

Introduction: Complement mannan-binding lectin (MBL) deficiency is associated with increased susceptibility to infections and autoimmune diseases. Previous studies suggested that the production of MBL is stimulated by thyroid hormones. The aim of our study was to investigate this association in patients with autoimmune thyroid diseases (AITD).Methods: Serum levels of MBL and parameters of the thyroid function were determined in 62 patients with Hashimoto...
