Clinical trials

This study will evaluate physical function, cardiorespiratory fitness, muscle strength, and quality of life in patients with Fabry disease and assess the effects of a 12-week physiotherapy-led exercise programme. Participants will be non-randomly assigned to an exercise intervention group or a control group receiving no study-specific exercise intervention. The intervention group will be assessed at baseline, immediately after the 12-week intervention, and 12 months after baseline. The control group will be assessed at baseline and 12 months after baseline.

The purpose of this clinical trial is to evaluate the efficacy and safety of inhaled tiotropium bromide (Spiriva Respimat) in preterm-born children and adolescents suffering from chronic bronchial obstruction. Preterm infants often experience persistent narrowing of the airways, which leads to shortness of breath, chronic respiratory symptoms, and reduced exercise tolerance. Tiotropium is a long-acting muscarinic antagonist (LAMA) that helps dilate the airways and facilitate breathing. While this medication is already approved for pediatric patients aged 6 years and older with severe asthma, its efficacy and safety have not yet been validated in the specific population of preterm infants with bronchial obstruction. This study aims to fill this clinical knowledge gap. This is a non-commercial, monocentric, prospective, randomized, open-label, phase IV study utilizing a 2x2 crossover design. The trial will enroll 50 participants aged 6 to 18 years. Each participant will undergo two distinct 3-month phases: a treatment period with daily inhaled tiotropium (5 µg once daily) and a control observation period without long-term anticholinergic therapy. The sequence of these periods will be randomly assigned to each participant. The primary objective is to demonstrate lung function improvement by evaluating the change in forced expiratory volume in 1 second (FEV1) expressed in liters and Forced Vital Capacity (FVC) expressed in liters between the treatment and control periods. No blood samples or invasive procedures are required for this study.

The project will study the impact of individually tailored lifestyle counselling compared to standard care on the parameters of NAFLD/NASH in patients with metabolic syndrome. The factors affecting the outcome (including clinical and laboratory parameters and microbiome profiling) will be evaluated.

The objective of the trial is to assess whether the combination of enoxaparine (LMWH) with progesterone increases the live birth rate compared to standard of care (no active treatment) in women with unexplained recurrent pregnancy loss.

This interventional study is part of a broader research project entitled "Bone Marrow Adipose Tissue in Relation to Bone and Energy Metabolism in Obesity and Type 2 Diabetes Mellitus." The broader project includes both a cross-sectional study evaluating bone marrow adipose tissue and bone marrow mesenchymal stem cells in people with different metabolic and bone disorders and the present dietary intervention study. The interventional study investigates whether caloric restriction changes bone marrow adipose tissue, bone health, whole-body metabolism, and the molecular and cellular characteristics of bone marrow mesenchymal stem cells in obese non-diabetic premenopausal women. A group of lean healthy premenopausal women will serve as a comparison group. Participants in the intervention group will undergo an eight-week formula-based very-low-calorie diet using Cambridge Weight Plan products, providing approximately 2.5-3.35 MJ (600-800 kcal) per day, followed by a dietary weight-maintenance phase. Participants will receive nutritional counselling, and dietary adherence, body weight, physical activity, and clinical status will be monitored during scheduled study visits. Clinical and laboratory assessments will be conducted at baseline and after 2, 6, and 12 months. Assessments will include magnetic resonance imaging and proton magnetic resonance spectroscopy of the lumbar spine to measure the amount and lipid composition of vertebral bone marrow adipose tissue. Bone mineral density and body composition will be measured using dual-energy X-ray absorptiometry, with particular attention to bone mineral density at the total hip and femoral neck. Additional measurements will include body weight, waist and hip circumference, body composition, physical activity, and fasting blood tests evaluating bone turnover, glucose and lipid metabolism, inflammatory markers, hormones, and adipokines. Bone marrow aspirates and abdominal subcutaneous adipose tissue biopsies will be obtained at baseline and after six months. Bone marrow-derived and adipose tissue-derived mesenchymal stem cells will be examined for changes in cellular composition, gene-expression profiles, metabolic activity, oxidative stress, differentiation capacity, and senescence-related characteristics. Single-cell RNA sequencing will be used to characterize specific bone marrow mesenchymal stem cell subpopulations. Bone marrow plasma and other biological samples will also undergo metabolomic, lipidomic, and proteomic profiling using high-resolution mass spectrometry. These analyses will be used to identify extracellular molecules and molecular patterns associated with glucose and lipid metabolism, inflammation, cellular senescence, and the response to caloric restriction. The study aims to determine whether diet-induced weight loss can improve the bone marrow microenvironment and modify vertebral bone marrow fat, bone parameters, and the metabolic and senescent phenotype of mesenchymal stem cells. The findings may help identify imaging, cellular, and molecular markers of obesity-related bone fragility.

Patients indicated for subtotal hysterectomy will be tested for High risk HPV and if the result is positive will undergo expert colposcopy and conisation if not indicated otherwise at the time of subtotal hysterectomy

The HART (HPV After chemoRadiotherapy) study is a prospective multicenter observational trial designed to evaluate the clinical utility of HPV testing in the follow-up of patients treated with definitive chemoradiotherapy (CRT) for cervical cancer. Current surveillance after CRT relies mainly on clinical examination and imaging, while the role of HPV-based molecular monitoring remains insufficiently defined. The study plans to enroll 120 patients with FIGO stage IB-IVA cervical cancer treated with primary radiotherapy with curative intent. HPV detection will be performed using two complementary approaches: PCR-based detection of HPV DNA from a cervical swab and analysis of circulating HPV tumor DNA (ctDNA) in peripheral blood. Samples will be collected before treatment and during follow-up at 3, 12, and 24 months after completion of CRT. The primary objective is to determine the sensitivity of these methods for detecting disease recurrence during a two-year follow-up period. Secondary objectives include evaluation of HPV clearance after treatment, comparison of HPV genotypes before and after therapy in cases of persistence, and comparison of the diagnostic performance of cervical HPV testing and ctDNA detection. The study aims to generate evidence supporting the integration of HPV-based molecular monitoring into routine follow-up, potentially enabling earlier detection of recurrence and more individualized surveillance strategies for patients after CRT for cervical cancer.

The aim of this study is to assess the extent of histopathological regression of severe cervical precancerous lesions (CIN 2 and CIN 3); evaluate the proportion of patients who experience the normalization of HPV test and cytology finding among those who were treated conservatively and those who underwent conization; and identify predictive parameters associated with regression. Based on this analysis, a model will be proposed to predict the likelihood of lesion regression.

Postural abnormalities (PA) negatively affecting the axial system are part of the symptoms of Parkinson's disease (PD). They occur in more than 20% of patients with PD especially in more advanced stages of the disease, contribute significantly to patient disability, affect respiratory functions, and reduce quality of life. Eighty-five percent of patients with forward trunk flexion (FTF) reported difficulties with swallowing (dysphagia), shortness of breath, and drooling. Previous studies in patients with PD also identified cough disorders (dystussia). Since cough and properly functioning swallowing are key mechanisms for airway protection, impairments in these functions lead to a higher risk of aspiration. The seriousness of this problem is clearly confirmed by the fact that aspiration pneumonia is the leading cause of death in patients with PD. Among non-pharmacological interventions for airway protection, expiratory muscle strength training (EMST) has been shown to be beneficial in patients with PD. Recent randomized controlled studies demonstrated a significant effect of EMST on dysphagia, dystussia, drooling, and dysarthria in patients with PD. However, the literature lacks data on the effect of EMST on dystussia in patients with PD and FTF, who, according to previous research, are also affected by restrictive ventilatory impairment, which negatively affects respiratory capacity and, in particular, cough strength. The aim of this study is to evaluate the effect of EMST on cough, swallowing, respiratory muscle strength, and drooling in patients with PD and forward trunk flexion.

The previous pilot study showed that two weeks of intensive expiratory muscle strength training (EMST) with SpiroGym was sufficient to significantly improve voluntary peak cough flow (PCF). The improvement was quantitatively comparable to that reported in other intensive EMST studies of longer duration. To explain this rapid improvement, we considered the potential contribution of SpiroGym's visual feedback. We assumed that real-time visual feedback increased training effort compared with conventional EMST performed without immediate feedback. The aim of this study is to evaluate the effect of visual feedback provided by the SpiroGym mobile application on performance during expiratory muscle strength training in patients with Parkinson's disease.

Postural abnormalities involving the trunk are prevalent in over 20% of patients with Parkinson's disease (PD). Pathological forward trunk flexion (FTF) is a drug-refractory complication in patients with PD leading to imbalance, pain and fall-related injuries. Deep abdominal muscle training is a key rehabilitation strategy for FTF, as muscles like the transversus abdominis and multifidus are crucial for lumbar stabilization. This training has been shown to improve body position and lumbar proprioception. Abdominal muscles are also responsible for forced expiration. Expiratory muscle strength training (EMST) utilizing forced expiration through expiratory trainer has emerged as a beneficial intervention in the non-pharmacological management of PD, positively impacting clinical aspects such as dysphagia, dystussia, hypokinetic dysarthria, and drooling. EMG study showed large abdominal muscles activity, particularly the transversus abdominis and internus obliquus abdominis during EMST. Therefore, EMST might also be effective in improving lumbar stabilization. Given the established role of abdominal muscles in trunk stabilization, it is plausible that activation of deep abdominal muscles during EMST with the right level of resistance might improve FTF in PD patients. No studies have yet examined the effect of EMST on posture in PD. The primary aim of this study will be to evaluate the effect of EMST on forward trunk flexion in patients with Parkinson's disease. The secondary aim will be to assess the potential duration of the EMST effect on postural abnormalities and its impact on patient stability.

The main mechanisms of airway protection include a properly functioning swallowing process and a cough. Studies focusing on patients with Parkinson's disease (PD) have previously demonstrated impairments in both swallowing (dysphagia) and coughing (dystussia). Aspiration pneumonia is the leading cause of death in individuals with PD. Swallowing function is directly related to body posture. Postural abnormalities (PA) are a common symptom of PD and significantly contribute to patient disability, affect respiratory function, and reduce quality of life. Previous research has shown that more than 20% of PD patients suffer from some form of PA. Most PD patients with a forward trunk flexion angle greater than 30 degrees report specific difficulties, such as dysphagia. A link has previously been demonstrated between postural abnormalities associated with flexed posture and restrictive ventilatory impairment. It can be assumed that this restrictive ventilatory impairment, which reduces the amount of air the patient can inhale into the lungs and subsequently exhale, negatively affects the strength of voluntary cough. However, this hypothesis has not yet been verified in the mentioned patient group. The primary aim of the study will be to examine the effect of forward trunk flexion (FTF) in Parkinson's disease on the airway defense system.

The goal of this clinical trial is to determine whether adding strength training to aerobic training has a comparable or greater effect on the clinical status of Parkinson's disease patients than a standalone aerobic training. \- Does combined strength-endurance circuit training provide added benefits to physical performance, disease severity, blood biomarkers, and quality of life in PD patients compared to standalone aerobic training? Participants will: * undergo outcome measurements before and after the 12-week intervention and a 3-month follow-up measurement, * visit the clinic twice a week for 1-hour training sessions. * selected patients will be given a smartwatch with a pedometer that will count their average number of steps before, during and after the training period

A prospective pilot feasibility study of prehospital ECPR in patients with refractory OHCA

Tru-cut biopsy (TCB) is a minimally invasive method to get an adequate sample from the lesion in order to tailor the appropriate management avoiding unnecessary surgery. The aim of our trial is to evaluate the adequacy, accuracy and safety of the method related to the final histology as reference standard.

The OSIRIS trial is an investigator-initiated, multicenter, multinational, open-label, randomized controlled trial with a 2:1 concealed allocation of refractory out-of-hospital cardiac arrest (OHCA) patients to the extracorporeal cardiopulmonary resuscitation (ECPR) based approach versus the conventional cardiopulmonary resuscitation (CCPR) approach.

The pilot study by Srp et al. (2021) proved that the SpiroGym app was feasible for supporting expiratory muscle strength training (EMST) in Parkinson's disease (PD) patients. Two weeks of intensive EMST coupled with SpiroGym were sufficient to significantly improve the participants' voluntary peak cough flow (PCF). The improvement was quantitatively comparable to the results of other intensive EMST studies with longer durations. When interpreting such rapid improvement, the impact of SpiroGym's visual feedback was considered. It was assumed that visual feedback increased training effort compared to regular training without immediate control. However, comparative studies were required to verify the possible additional effects of visual feedback on voluntary PCF compared to EMST without feedback.

The primary aim of the project is to analyse gene expression in individual types of ectopic endometrium (ovarian endometriosis, peritoneal endometriosis, deep infiltrating endometriosis) and compare it with gene expression in eutopic endometrium. The analysis focuses on the identification of genes with significantly increased expression in each type of ectopic endometrium and comparison of their expression with the degree of disease, ovarian reserve and clinical manifestations of the disease (pain, infertility).

The primary objective of the trial is to compare the impact and safety of delayed salvage therapy (dSRT, i.e., SRT initiated at PSA values of 0.4-0.5 ng/ml) to those of early salvage therapy (eSRT, i.e., at PSA levels of 0.2 ng/ml) in patients with biochemical relapse after radical prostatectomy. The secondary objective of the trial is to perform analysis of the subgroups of patients to determine which patients are most likely to benefit from dSRT Exploratory objective of the trial is to determine whether selected molecular genetic parameters (172 candidate genes and molecular alterations) and known clinical parameters can be used to identify potential predictors of worse prognosis in patients with known risk factors for relapse after radical prostatectomy, thereby augmenting and refining patient stratification, optimizing their therapy, and clarifying the proper timing of multimodal therapy
