Introduction: Reduction of quality of life in patients with chronic hypoparathyroidism (HPT) has been reported by several studies. Additionally, self-report data point to a higher prevalence of anxiety disorders in HPT compared to patients after thyroidectomy.Objectives: To characterize psychiatric diseases in a systematically reviewed cohort of patients with chronic HPT.Methods: We systematically assessed psychiatric comorbidities...

Adrenal crisis (AC) is a life threatening condition in chronic adrenal insufficiency (AI). Furthermore, recent data demonstrate increased mortality in this patient group.Incidence and causes of adrenal crisis as well as general morbidity and hospitalization was assessed in 472 patients in a prospective trial. Patients were contacted via mail every 6 months and in case of AC additionally by phone to evaluate the exact circumstances of AC. Criteria for AC ...

Adrenocortical carcinoma (ACC) is part of the Li-Fraumeni tumour syndrome which is due to germline mutations in TP53. Recent studies demonstrate low penetrance mutations leading to later tumour manifestation. Furthermore, in ACC mutations outside the hotspot region have been found. TP53-polymorphisms have also been described to impact on p53 function. We, therefore investigated TP53 sequence alterations in a large cohort of adult patients with ACC.Method...

Subject: Treatment options for adrenocortical carcinoma (ACC) are still unsatisfactory. We could recently demonstrate that several patients with ACC exhibit a high and specific uptake of 123I-Iodometomidate (123I-IMTO). Therefore, we investigated if 131I-IMTO holds potential for radiotherapy in ACC.Methods: Dosimetry with 40 MBq I-131-IMTO was performed over 5 days in 7 patients and calculated activities were administered on a compassionate use basis in ...

Introduction: Chemokines and their receptors (CR) have been demonstrated to be involved in tumour growth and site specific metastasis. Furthermore, several cytokines have been described to modulate adrenocortical function. Therefore, we have investigated the expression pattern and functional activity of chemokine receptors and of corresponding chemokines in adrenocortical tissue.Methods: Chemokine and CR expression was assessed by RT-PCR in normal adrena...

Objective: There is evidence that current replacement regimens fail to restore well-being in patients with adrenal insufficiency (AI). No data is available on the effect of different therapeutical regimes (hydrocortisone, prednisolone, cortisone acetate) on the quality of life in these patients.Methods: About 883 patients with adrenal insufficiency were contacted, 526 patients participated (60%) and received a disease specific questionnaire and three sta...

Objective: There is evidence that current replacement regimens fail to restore well-being in patients with adrenal insufficiency. No data is available on the effect of twice or thrice daily administration of hydrocortisone on the quality of life in these patients.Methods: About 883 patients with adrenal insufficiency were contacted, 526 patients participated (60%) and received a disease specific questionnaire and three standardized questionnaires (SF36, ...

Adrenal crisis (AC) is a rare but life-threatening complication in chronic adrenal failure. Here we evaluated frequency, causes and potential risk factors of AC in a large sample of patients with primary AI (PAI) or secondary AI (SAI).In a cross-sectional study 883 patients with AI were contacted by mail. 526 patients agreed to participate and received a disease specific questionnaire. Diagnoses and co-morbidities were verified by review of medical recor...

Objective: Isolated ACTH-deficiency (IAD) is considered a rare autoimmune endocrinopathy most frequently associated with autoimmune thyroid diseases (ATD). We have previously diagnosed IAD in four patients with primary hypothyroidism and negative TPO antibodies. The aim of this study was to determine the prevalence of undiagnosed IAD in patients with ATD.Methods: We studied 45 patients with ATD on stable L-thyroxine replacement (dose range...

Objective: There is evidence that current replacement regimens fail to restore well-being in patients with adrenal insufficiency (AI). No data is available on the effect of different therapeutical regimes (hydrocortisone, prednisolone and cortisone acetate) on the quality of life in these patients.Methods: Eight hundred and eighty three patients with adrenal insufficiency were contacted, 526 patients participated (60%) and received a disease specific que...
