NCT ID: NCT06291142 Enrolling by invitation - Systemic Sclerosis Clinical Trials

Early Diagnosis of SSc in the General Rheumatology Clinic - Pilot

Start date: November 22, 2023
Phase:
Study type: Observational

The goal of this observational pilot data acquisition study is to establish if target users can obtain diagnostic quality images in the clinic, from participants with Systemic Sclerosis (SSc), and SSc spectrum conditions. The main questions it aims to answer are: - Can a range of healthcare professionals, including non-specialists, use the capillaroscopy image acquisition system to take high quality images that can be used to create a clinical report? - Can the investigators collect user and patient feedback on the usability of the capillaroscopy system, to help develop the software and to develop the clinical report - Which microscope light source, from four different light wavelengths is better to see the blood vessels in skin with more melanin content. Participants will be asked to attend a single clinic visit where they will undergo a brief, non-invasive nailfold capillaroscopy examination, using the software-guided capillaroscopy system. Participants and rheumatology healthcare professionals will be invited to take part in one or more focus groups and interviews, to collect feedback and to contribute to the development of the image acquisition software and the clinical report.

NCT ID: NCT05204784 Recruiting - Systemic Sclerosis Clinical Trials

Rheopheresis for Raynaud's and Digital Ulcers in Systemic Sclerosis

RHEACT
Start date: February 28, 2022
Phase: N/A
Study type: Interventional

In this feasibility study, we aim to explore therapeutic Rheopheresis (RheoP) as a novel treatment option for SSc-associated Raynaud's phenomenon and/or digital ulcers and compare it to the standard of care treatment (intravenous iloprost. RheoP has been used for RP/DU with some success in observational studies, nevertheless, the optimal treatment modality, duration, or frequency of RheoP (and PEX in general) in SSc has not been established as of yet.

NCT ID: NCT05125029 Recruiting - Raynaud Phenomenon Clinical Trials

Botulinum Toxin in Raynaud's Phenomenon

Start date: February 10, 2022
Phase: Phase 4
Study type: Interventional

Raynaud's Phenomenon (RP) is the most common vasospastic disorder encountered by hand surgeons with an estimated prevalence of 5% in the general population. It's manifestations are broad, and can range from minor to severe. Sometimes it can be refractory to treatments. The goal of this study is to evaluate the efficacy of Botulinum toxin (BT) in the treatment of treatment refractory RP by objective and subjective measures.

NCT ID: NCT04898036 Withdrawn - Raynaud Phenomenon Clinical Trials

Phototherapy For Treatment Of Raynaud's Phenomenon

Start date: August 2022
Phase: N/A
Study type: Interventional

To determine if blue light therapy can improve the symptoms of Raynaud's phenomenon, and provide parameters for ultimately designing commercial treatment devices, an investigational stationary phototherapy unit was designed and built.

NCT ID: NCT04854850 Completed - Fatigue Clinical Trials

Apollo Device for Fatigue in Systemic Sclerosis

Start date: July 7, 2020
Phase: N/A
Study type: Interventional

The purpose of this study is to learn about the effect of Apollo (a vibrating wearable about the side of an Apple Watch) on fatigue, Raynaud symptoms, depression, quality of life, and disease symptoms in patients with systemic sclerosis. SSc patients frequently have fatigue as a characteristic feature of their disease and fatigue negatively impacts quality of life (Haythornthwaite 2003, Richards 2003, Suarez-Almazor 2007, Basta 2017). The prevalence of fatigue among SSc patients is 75%, with 61% ranking fatigue among their top three most distressing complaints. Fatigue is also associated with poor sleep quality, greater pain and depressive symptoms (Sandusky 2009). We hypothesize that treatment with Apollo over 1 month will improve fatigue. If successful, the Apollo technology will be the first treatment option for fatigue and Raynaud's in this population.

NCT ID: NCT04644523 Completed - Raynaud Phenomenon Clinical Trials

Dermoscopy in Primary Raynaud's Phenomenon

VASCUL-R
Start date: January 1, 2021
Phase:
Study type: Observational

Raynaud's phenomenon (RP) is very frequent in general population (up to 10%). Nailfold capillaroscopy (NFC) is recommended for patients presenting RP, to eliminate systemic disease such as systemic sclerosis. NFC is not easily available in clinical practice. Dermoscopy, used for pigmentary skin lesion screening, may help to detect giant loops, hemorrhages or other capillaries anomalies. However, no study has evaluated the performance of dermoscopy in primary RP. The objective is to determinate which items in dermoscopy are correlated with a normal NFC and predict with a good negative predictive value, a normal NFC in RP patients. The secondary objective is to assess inter-observer reproducibility of dermoscopy in patients with RP.

NCT ID: NCT04388176 Completed - Systemic Sclerosis Clinical Trials

Cold Challenge With C21 in RP

Start date: January 3, 2020
Phase: Phase 2
Study type: Interventional

This is a randomised, double-blind, placebo-controlled, cross-over phase 2 trial investigating the effect of C21 on cold-induced vasoconstriction in subjects with Raynaud's phenomenon secondary to systemic sclerosis. The purpose of the trial is to achieve a vasodilatory effect in subjects with Raynaud's phenomenon by stimulation of the AT2R (angiotensin II type 2 receptor) with C21.

NCT ID: NCT04015193 Recruiting - Raynaud Phenomenon Clinical Trials

Follow-up of SPTS in Patients With Raynaud's Phenomenon

Start date: March 28, 2019
Phase:
Study type: Observational

Background: Raynaud's phenomenon is a vasospasm of the extremities, leading to extensive discomfort in daily life and potentially severe ischemia. Some patients are resistant to conventional vasodilatory drug treatment. In the University Medical Center Groningen, single-port thoracoscopic sympathicotomy (SPTS) was developed. This is a new minimally invasive endoscopic technique, extensively limiting surgical burden. In many hospitals in the Netherlands, this operation is sometimes performed on patients with Raynaud's phenomenon. However, the techniques used are more invasive than the SPTS technique. Furthermore, studies on sympathectomy and sympathicotomy in Raynaud's are limited and encompass obsolete more invasive techniques. Also, it is unclear which patients would benefit the most and for how long and in which percentage of patients treatment effects persist over time. In a recent study on the new SPTS technique, it was found that one month after the procedure, the Raynaud's attacks were substantially reduced and the hand perfusion increased on the operated side. Based on these short term effects and previously reported broad experience with this technique for other indications, it is possible to offer this option to a broader range of patients with Raynaud's as a reasonable and safe treatment option. However, whether the effects persist on the long-term needs to be established. Main research question: The aim of the study is to assess the 5 year efficacy and outcome in patients with primary and secondary Raynaud's phenomenon in whom SPTS has been performed. Design (including population, confounders/outcomes): Patients with Raynaud's, who will undergo SPTS in patient care setting, will be included. Data from the patient file will be collected, including vascular measurements to assess hand perfusion, a Raynaud diary (Raynaud condition score, duration and frequency of the attacks), quality of life questionnaires, and adverse events.

Localized Effects of PBM and Exogenous NO on CREST Patients Calcinosis Cutis & Raynaud Phenomenon

Start date: June 20, 2019
Phase:
Study type: Observational

Background CREST is an acronym for the cardinal clinical features of the syndrome (Calcinosis, Raynaud phenomenon, Esophageal dysmotility, Sclerodactyly, and Telangiectasia) and part of the heterogeneous group of sclerodermas. Calcinosis is the pathologic calcification of soft tissues. When symptomatic, they can be tender and painful, ulcerate, and drain a white chalky substance. With time, heterotopic bone formation may occur. Inflammatory reactions also intermittently occur at the site of calcinosis. It has been suggested that TGF-beta3 plays a major role in the pathogenesis of calcinosis. A variety of medical therapies have been used to try to alleviate patient symptoms. These include pharmacological approaches (e..g., warfarin), surgical curettage or excision, as well as carbon dioxide laser treatments. No consistently reliable pharmacological treatment seems to be available to prevent or eliminate calcinosis. Curettage and excision and carbon dioxide laser of localized painful large deposits can relieve symptoms but recurrence is common. In addition, aggressive curettage or excision can damage deeper neurovascular structures. While calcinosis is associated with significant morbidity its treatment remains a challenge. Photobiomodulation (PBM) has been shown to promote wound healing, suppress inflammatory reactions and regulate collagen synthesis in a number of in vitro and in vivo studies. Human skin contains photolabile nitric oxide (NO) derivatives which decompose after UVA irradiation and release vasoactive NO. However, aside from blue light, barely nothing has been reported about the effects of red and NIR wavelengths. Method A custom-built air tight sleeve which envelopes the forearm of a subject will be used to measure the NO emanating from the skin under photobiomodulation conditions (red & NIR) and quantified by chemiluminescence detection. Simultaneously, CREST patient's hands exhibiting calcinosis and/or Raynaud phenomenon will be exposed to exogenous gaseous nitric oxide (INOMAX) to determine the vascular impact of this approach. This case series will assess Light Emitting Diode (LED) based PBM therapy as a treatment alternative for cutaneous calcinosis and the effects of gaseous NO on calcinosis and/or Raynaud phenomenon in CREST patients.
