NCT ID: NCT05055115 Recruiting - Clinical trials for Eustachian Tube Dysfunction

Ph.D.-Project: Eustachian Tube Dysfunction: Causes, Diagnosis, Treatment, and Prognosis

Start date: June 1, 2021
Phase: N/A
Study type: Interventional

Background: The Eustachian Tube (ET) is a mucosa-lined connection between the nasopharynx and the middle ear cavity. It is believed to have three functions: 1) ventilation of and pressure equalization in the middle ear cavity, 2) mucus drainage from the middle ear, and 3) protection against sound and infection from the nasopharynx1. In adults, Eustachian Tube Dysfunction (ETD) can cause complaints from one or both ears. For many years, various definitions of ETD have been used, impairing the opportunity to compare studies. However, in 2015, an international consensus on definition, types, clinical presentation, and diagnosis of ETD was published by Schilder et al2, which has been adopted by all the Scandinavian countries. The symptoms include pressure (fullness), and/or pain in the ear, muffled hearing, and overall discomfort. Furthermore, chronic ETD can result in tympanic membrane retraction, atelectasis of the middle ear cavity, and ultimately formation of cholesteatoma3. Unfortunately, the symptoms of ETD are multiple and inaccurate giving rise to varying estimates of the prevalence. As an example, a study in UK found a 0.9 % prevalence of ETD4. In addition, clear guidelines on diagnostics and treatment are not currently available due to the fact, that no objective test for detection of ETD exists. In the need of a symptom scoring system, the patient reported Eustachian Tube Dysfunction Questionnaire (ETDQ-7) has been developed and validated in English5. Yet, translation into other languages as well as validation in other settings are necessary in order to substantiate the applicability of ETDQ-7. ETD is associated with a lack of opening of ET. It is believed that the length, diameter and angle of ET influences its ability to open regularly, thus affecting its function. A short, narrow and angled ET may predispose to ETD. However, the imaging available to visualize ET are not accurate enough to diagnose ETD. A direct test of the function of ET is not available. Tubomanometry is a relatively new method developed to directly test the opening of ET, but is yet to be validated6. Both non-surgical and surgical treatment options to improve the function of the Eustachian Tube are available. Non-surgical management includes pressure equalization methods (e.g. the Valsalva maneuver), antihistamines, treatment with decongestants, and nasal douching with a saline solution. Surgically, ventilation tubes are often used to treat ETD. In case of adenoid hypertrophy obstructing the pharyngeal opening of ET, adenoidectomy is recommended. Balloon Eustachian Tuboplasty (BET) was introduced in 2010 by Ockermann et al7. BET is a non-invasive procedure performed under general anesthesia. During the procedure, a catheter is inserted either endonasally or transtympanic into ET, and a balloon is inflated with water for approximately two minutes. Various heterogeneous studies have shown a short-term effect of BET, but long-term effects are unclear8. In summary, despite the assumption of being a common condition, the field of ETD suffers from lack of precise definition, diagnostic criteria, identification of underlying causes as well as purposeful treatment, and prognostic factors. Especially, long-term effects of BET need further investigation. Therefore, in an effort to fill out the gap of knowledge about ETD, the following specific aims are proposed:

NCT ID: NCT05055037 Completed - Clinical trials for Post Traumatic Stress Disorder

Neurofeedback as a Treatment for Trauma-affected Refugees

Start date: November 22, 2018
Phase: N/A
Study type: Interventional

Neurofeedback (NF) is a form of treatment that can assist individuals in learning to control their brain wave activity. NF-studies have shown promising results in reducing PSTD-symptoms among military veterans, but there are no published peer-reviewed studies with refugees. However, preliminary studies from Malmö and Sydney indicate that refugees could benefit from NF. Therefore, at the Competence Centre for Transcultural Psychiatry (CTP) a longitudinal feasibility study, testing NF for trauma-affected was started. The study contains both a quantitative and a qualitative substudy. In in the quantitative substudy, where a total of 32 participants have been included, the aim was to evaluate the feasibility of NF with trauma affected refugees using a quantitative perspective. The NF intervention offered was 12 training sessions of 12-20 minutes NF, and the outcome measures were self-administered questionnaires and semi-structured interviews collected before and after the intervention. In a subsample of eight participants of those included in the quantitative substudy, qualitative in-depth interviews were carried out. The participants were offered two interviews; one before the first NF training and one during the treatment course. The aim of the qualitative substudy was to evaluate the feasibility of NF with trauma-affected refugees by examining the participants' thoughts and expectations prior to participating in NF treatment as well as their experience with the treatment after a few sessions.

NCT ID: NCT05053139 Not yet recruiting - Haemophilia A Clinical Trials

A Research Study Investigating Mim8 in Adults and Adolescents With Haemophilia A With or Without Inhibitors

Start date: December 3, 2021
Phase: Phase 3
Study type: Interventional

This study is investigating how Mim8 works compared to other medicines in people with haemophilia A, who either have inhibitors or do not have inhibitors. Mim8 is a new medicine that will be used for prevention of bleeding episodes. Mim8 works by replacing the function of the missing clotting factor VIII (FVIII). When and how often participants will receive Mim8 is dependent on their previous treatment - but is otherwise decided by chance. The study will last for 72-124 weeks (17-29 months) depending on how long participants will be followed before it is decided when they start receiving Mim8 - the period before this is decided is called the 'run-in'. Participants will have 13-17 clinic visits. Mim8 will be injected into a skinfold on the stomach with a thin needle either once a week or once a month.

NCT ID: NCT05052385 Recruiting - Clinical trials for Steroid Refractory GVHD

ECP Combination Study

Start date: April 13, 2021
Study type: Observational

Extracorporeal photopheresis (ECP) offers an alternative to standard immunosuppression and shows an immunomodulatory rather than an immunosuppressive effect, which is associated with less toxicities and side effects. Additionally ECP has been shown to allow tapering of steroids and immunosuppressant agents which should be a goal of GvHD therapy. ECP has been used for the management of GvHD since first described in 1994 and as its use has continued over the decades. The treatment was incorporated into a number of guidelines as a second line therapy in steroid refractory or steroid dependent GvHD patients. As well as being used in addition and after steroids, it is also used in combination with CNI Inhibitors, MMF and other immunosuppressant agents. However, despite the current widespread use of ECP in the treatment of patients with GvHD, clinical data from randomized studies is limited and small prospective and retrospective trials are the main evidence base .This is also the case for other commonly used immunosuppressant agents, which have been used in GvHD since ECP was introduced. The systematic review concluded that ECP is an effective therapy for oral, skin, and liver SR-cGVHD, with modest activity in lung and gastrointestinal SR-cGVHD. In the USA Ibrutinib is the only FDA approved agent for second line cGvHD therapy once steroid therapy has failed and Ruxolitinib had been approved in the USA for the treatment of steroid refractory GvHD. While studies have shown the effectiveness and safety of ECP in GvHD treatment, there is limited data to show how it is being used in combination with the recently approved agents. Using existing registry data targeting centres where the newer agents are being used and enhancing the capture of treatment data we believe we can undertake a larger scale study, which will include the new treatment protocols. The aim of the current study is to improve the evidence basis on the potential benefit of ECP use as treatment of GVHD.
