Effects of Cross-sex Hormone Therapy on Eating Behavior, Metabolism, Energy Balance and Cardiovascular System

Current study aims to characterize five highly interconnected physiological systems in patients undergoing cross-sex hormone therapy - namely glucose and lipid metabolism, energy balance, eating behavior, functional brain networks involved in the regulation of eating behavior and the cardiovascular system - to gain novel insights into the effects of sex hormones on the human body. Gathered information will help to identify pathophysiological mechanisms for the development of overeating/obesity, insulin resistance, and cardiovascular disease. Secondarily, the relationships between the gut and oral microbiomes and metabolomes and circulating bacterial signatures will be investigated in relation to the other pervasive physiological systems. Current study is an observational study. The decision if the patient's request for cross-sex hormone therapy can complied with (i.e., if cross-sex hormone therapy is medically indicated) is made prior to the first contact with the study center and with the outpatients clinic for Endocrinology at the University Hospital in Leipzig. Decision ifor treatment is made according to national and international guidelines. Treatment of study participants with testosterone and estradiol/antiandrogens is not affected by the study. During the course of the study no invasive interventions are being performed.

Microangiopathy in Diabetes

This clinical trial aims to evaluate the use of a contactless and non-invasive technique to measure the properties of the skin's microcirculation and its regulatory functions in both healthy individuals and patients with microvascular disease associated with type 1 diabetes. It is hoped that the study results will lead to the development of a useful method for detecting diabetic complications at an early stage, thereby enabling treatment and preventive measures before the onset of severe microangiopathy.

Post-transplant Thrombotic Microangiopathy: Evaluation of Outcomes at the Bologna Kidney Transplant Centre

It is a retrospective-prospective, single-centre, non-pharmacological, retrospective tissue study carried out for scientific and health protection purposes. It involves the systematic collection of clinical information from patients diagnosed with PT-TMA

Poznan Prospective Study of Type 1 Diabetic Patients

The purpose of this study is to evaluate the development and progression of chronic complications (retinopathy, neuropathy, diabetic chronic renal disease, cardiovascular events) in patients with type 1 diabetes treated from the onset of the disease with recommended method of intensive insulin therapy. All patients attended a five-day structured training program during first hospitalization and re-education once year during the observation. After five years of observation and next - once a year chronic complications are assessed. The investigators would like to evaluate also the relationship of the management of the disease, knowledge about the treatment and diabetes, insulin resistance and inflammatory markers with development and progression of chronic complications.
