There are about 1447 clinical studies being (or have been) conducted in Croatia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Vedolizumab is a medicine that helps to reduce inflammation and pain in the digestive system. In this study, children and teenagers with moderate to severe ulcerative colitis will be treated with vedolizumab. The main aim of the study is to check if participants achieve remission after treatment with vedolizumab. Remission means symptoms improve or disappear and an endoscopy shows no or limited signs of disease. The study is also evaluating side effects of vedolizumab in the children and teenager with moderately to severely active ulcerative colitis. Participants will receive 3 infusions of vedolizumab over 6 weeks. Then, those who have a clinical response will receive 1 of 3 doses of vedolizumab once every 8 weeks. They will receive the same dose every time.
The objective of the current study is to evaluate the effect of a probiotic mixture on the adequate relief and faecal microbiota in obese patients with irritable bowel syndrome
Pertussis is a vaccine preventable disease caused by Bordetella pertussis. Older children and adolescents with pertussis continue to be a significant source of infection for incompletely vaccinated infants who are in harm for developing severe disease. The primary objective of our study is to estimate the duration of protection elicited by the current vaccination schedule against pertussis in Croatia.
Ap¬plications of CO2 insufflation for endoscopic procedures have been reported for the performance of routine colonoscopy, small bowel endoscopy, endoscopic retro¬grade cholangiopancreatography (ERCP) and endoscopic submucosal dissection in the upper and lower gastrointestinal tracts. These studies showed that CO2 insufflation reduces the post-procedural abdominal distension and pain without CO2 retention and adverse events. However, there has been no report on the safety and efficacy of CO2 insufflation in PEG procedures in adults or in children. In the present study, we would like to evaluate by randomized controlled trial: the safety of the CO2 insufflation during PEG and the inhibi¬tory effects of CO2 insufflation on bowel distension after PEG.
Temporomandibular disorders (TMD) are the most common orofacial pain disorders of non-dental origin with the prevalence of 6.1-10.2%, and incidence of 3.9%. Observable pathology is mostly absent, and the etiology often remains unknown. Since some other painful conditions of unknown origin (eg. fibromyalgia), also imply genetic factors, the aim of the study is to investigate genetic predisposition in relation to the risk for TMD onset. This will be achieved through analysis of polymorphisms in the selected genes in TMD patients (DC/TMD) and matched control subjects. The possibility of involvement of specific polymorphisms in modulation of therapy response will also be investigated. The hypotheses: (I) the Single Nucleotide Polymorphism (SNPs) clustering will be dependent on presence or absence of TMD (comparison of patients with control subjects), and will possibly depend on source of pain, pain intensity, presence of bone changes, psychological features and previous orthodontic therapy, and (II) SNPs will influence the treatment response. Along with anamnestic and clinical examination and occlusal splint therapy, genomic DNA will be analyzed from the buccal swabs. Isolated DNA will be used for the determination of 19 polymorphisms of selected genes using Real-Time PCR method. The analysis of salivary oxidative stress markers and opiorphin will be also performed, as their relationship with TMD has been shown previously. This time, their concentration will be associated with polymorphisms in the promoters of genes responsible for their synthesis. The investigators expect to show that particular gene profile or group of SNPs represent a risk factor for TMD development. Innovative approach of the concept of determining the genetic predisposition for TMD has the potential for development of commercial genetic test with potential for risk estimation in relation to TMD onset. This could enable early interventions and active avoidance of environmental risk factors.
Patients diagnosed with acute pancreatitis regardless of etiology, severity of disease, and prior attacks will be randomized in two groups. The intervention group will receive a balanced crystalloid (Plasmalyte) at a rate of 10 ml/kg during the first 60 min and then continued at 3 ml/kg/h for the next 72 hours. The control group will receive normal saline at the same rate.
Geriatric presentations to emergency services comprise a significant percentage of all emergency service presentations in Europe and it has been reported that 3-23% of all emergency service presentations from various regions of the countries. There are specific management practices for patients who are 65 years and older at emergency services. On the other hand several risk-scoring systems have been developed to define the severity class of the patient during their initial evaluation at emergency services.Only a few studies in the literature have evaluated risk-scoring systems for the geriatric patient group.Several studies have reported that risk-scoring systems, such as Identification of Seniors at Risk and Triage Risk Screening Tool, which are specifically developed for geriatric patients over 65 years who present to emergency services, are not sufficiently effective for evaluating patients in more severe conditions. Previously the TEDGeS (Turkish Emergency Departments Geriatric Scoring Study) pilot study was carried out and published by some of the investigators of this project.This pilot study enrolled all geriatric patients (age ≥ 65 years) and carried out in 13 centers from different cities of Turkey. This pilot study showed that geriatric patients not only constitute significant proportion of emergency department presentations but also these patients need more hospitalization. The predictive powers of the Modified Early Warning Score, Rapid Emergency Medicine Score and The Vital PAC Early Warning Score for hospitalization and mortality in geriatric patients those presented to emergency department are significantly high and might be concerned in the emergency department triage of these patients. Within the light of these pilot study results, the investigators have decided to execute this prospective, multinational, multicentric study with the main objective to determine the epidemiological and age related characteristics of geriatric patients presenting to the emergency department across Europe and evaluate early warning scoring systems systems regarding hospitalization, ICU admission and in-hospital mortality for geriatric patients.
Patients with idiopathic dilative cardiomyopathy who have systolic left ventricular dysfunction (NYHA III - IV) despite adequate therapy according treatment guidelines of heart failure and who have a baseline left ventricular ejection fraction of ≥25% and ≤35 will receive a C-MIC System and microcurrent therapy after device implantation with optimal medical management. At the end of the study after 6 months, the C-MIC System will be turned off. The control group will receive optimal medical management without device implantation.
The study will investigate changes in certain locomotor parameters as early predictors of disease in smokers who are prone to develop chronic obstructive pulmonary disease (COPD).
The purpose of this study is to evaluate the efficacy and the safety of two doses of CHF6001 (Tanimilast) as add-on to maintenance triple therapy in the target patient population.
