Active clinical trials for "Immune System Diseases"

The purpose of the study is to gain a deeper understanding of the impact of asthma attacks on the lives of patients who experience them. This will help us to describe the true extent of the impact of asthma attacks on factors of importance to patients which have not previously been well described, including the psychological, social, financial and emotional burden of asthma attacks. Additionally, it is hoped that detailed questioning regarding features of asthma attacks from a patient perspective will improve our understanding of patient recognition of attacks, consistency of certain features of attacks and patient views regarding preventative strategies for attacks. Patient experiences of asthma attacks are poorly described in previous research. Hence this work is expected to provide useful insights into these experiences which will contribute to improvements in detecting, treating and preventing asthma attacks. The study will consist of a one-off interview lasting about 45 minutes with patients who have recently had asthma attacks. We plan to recruit patients for the study from an outpatient clinic for those who have had a recent attack or from a register of patients who have volunteered for future asthma research studies. The interviews will take place in person at the Respiratory Research Unit at the Nottingham City Hospital or over the telephone depending on patient preference.

The purpose of this study is to determine the predictive value of a mRNA signature and liquid biopsy in patients with Diffuse Large B cell lymphoma.

The SECOND SOUFFLE survey focuses on aspects of care and quality of life in a period when the landscape of severe asthma is changing in the context of biotherapies. Moreover survey on care pathway and quality of life of the asthmatic severe population according to their phenotype have never been done. It is likely to bring results in a relatively fast time, results that can lead to guide the criteria collected in RAMSES a national severe asthma cohort and future research tracks of this cohort.

A weekly questionnaire is sent to patients and parents of patients who are vulnerable for infections. Possible symptoms of COVID19 are asked for and use of healthcare services and testing for COVID19. Weekly reports are being send to the national institutions to update advice given to this group.

Treatment of acute relapsing multiple sclerosis (MS) has remained largely unaltered within past years. However, evidence defining the exact role of apheresis treatment in the therapeutic sequence is still incomplete. INCIDENT-MS evaluates the mechanism of action of immunoadsorption compared to escalated methyl prednisolone treatment in steroid-refractory MS relapses and thereby will help to identify predictive markers for optimal treatment choice and will generate further insights into the pathophysiology of MS relapses.

Each Multiple Sclerosis patient will be submitted to Cognitive Abilities Screening Instrument (CASI), Expanded Disability Status Scale, Epowrth Sleeping Scale(ESS),Fatigue Severity Scale(FSS), Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Headache Disability Index, specific questionnaire based on International Headache Society (IHS) recommendations

This is a non-interventional, Phase 4 study designed to improve understanding of current clinical practice in the treatment of CLL/SLL and to describe treatment pattern and evaluate outcomes of ibrutinib-treated CLL patients in China. This study will include both retrospective and prospective data collection.

One of the best understood mechanisms by which cytokines activate signals, thus eliciting specific responses in target cells, involves enzymes such as Janus kinases (JAKs) and transcriptional factors such as signal transducers and activators of transcription (STATs). For immune mediated diseases, both activating and inactivating mutations of JAKs and STATs may cause abnormalities in immune homeostasis. Polymorphisms of JAK/STAT genes have been linked to susceptibility for rheumatoid arthritis (RA) , systemic lupus erythematosus (SLE), psoriatic arthritis (PA) and inflammatory bowel disease (IBD) . Janus_kinase 3 expression will be evaluated in the serum and renal tissue of lupus patients during active stage of the disease through this study

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding Rheumatoid Arthritis

Correlation of serum lactate and activity of multiple sclerosis and its correlation to different type of MS
