Safety and Efficacy of Tofacitinib for Chronic Granulomatous Disease With Inflammatory Complications...
Chronic Granulomatous DiseaseInflammatory Gastrointestinal Disease2 moreBackground: Chronic granulomatous disease (CGD) is a disease of the immune system, which is how the body fights germs. People with CGD get infections easily and have other health problems. Some medicines to treat CGD have a lot of side effects and do not always work. Researchers want to see if a new drug can help. Objective: To see if tofacitinib is safe to use for treating chronic CGD. Eligibility: Adults aged 18 and older with CGD who have not had success with other treatments and who are enrolled on NIH study # 93-I-0119. Design: Participants will be screened with the following: Physical exam Medical history Blood, urine, and stool tests Pregnancy test, if needed An upper gastrointestinal endoscopy and/or colonoscopy, if needed for their symptoms. Tissue samples will be collected. Skin assessment, if needed Participants will repeat some screening tests at visits. Participants will complete questionnaires about their general health and how CGD affects their daily life. Photographs will be taken of their skin, if needed. They will have lung function tests, if needed. They will have a computed tomography (CT) scan of the chest, abdomen, and pelvis, if needed. A CT scan uses X-rays to create pictures of the inside of the body. Participants will gradually reduce the amount of some CGD medicines they take. Then they will take tofacitinib as a pill twice a day for 3 months. They will keep a drug diary. They will have monthly study visits. They will have a follow-up visit about 1 month after their last study drug visit. Participation will last for about 6 months.

The pilot study will be implemented as a 2-arm trial with local healthcare providers and patients with skin diseases over a 3-month follow-up period.
Patient Reported Outcomes With UVA-1 Therapy for Treatment of Sclerosing Skin Diseases
SclerodermaSystemic2 moreThe purpose of this study is to assess the degree of improvement seen patient reported outcomes after 30 sessions of UVA-1 therapy in treating systemic scleroderma, morphea, and sclerodermatous Graft-Versus-Host Disease. While patients have verbally reported improvement of their sclerosing skin disease with UVA-1, patient reported outcomes have not been rigorously studied. In sclerosing skin diseases where clinical change is difficult to measure, patient reported outcomes may offer a better way to study the impact of treatments like UVA-1. This will be a non-blinded, non-randomized prospective trial using UVA-1 phototherapy in patients with established sclerosing skin disease. Patients will report the severity of their condition using multiple patient reported outcomes and will also be analyzed using multiple clinical investigator assessments at the beginning and end of 30 treatment sessions.

Residual Disease MEMory in PSOriasis Skin During EnstiLAR® and Narrow-band Ultraviolet B Therapy:...
Psoriasis VulgarisPsoriasis4 morePsoriasis is a non-communicable chronic immune-mediated disease. Psoriatic skin is characterized by excessive proliferation of skin cells and infiltration of immune cells. The cause of psoriasis is so far unknown. Established therapeutics include topical, oral-systemic, biologic, narrow-band ultraviolet B (NB-UVB). A persistent antipsoriatic effect by the newest biologic therapies has been demonstrated after treatment discontinuation. However, the remittive hallmark of psoriasis suggests the existence of a molecular scar, a kind of disease memory, in clinically healed skin. It has been suggested that this disease memory can be attributed to the tissue-resident memory T (TRM) cell. The main purpose of the study is to investigate whether (NB-UVB) treatment and concomitant Enstilar® treatment can change the amount of TRMs in the skin as well as change the expression in the microenvironment around these cells in the skin from psoriasis patients. In addition, the investigators will investigate whether the treatment can change the quantity and types of other psoriasis-related cells in the skin. In addition to this, the investigators will also examine the effect of treatment on patient-related parameters.
Single-cell Transcriptome Identification of UV- and Visible-light-induced Genes in Human Melanocytes...
Skin DiseasesMedical condition and pathology studied skin pigmentation. Justification / rationale for the study UV are both the physiological stimulus for skin pigmentation and the main etiological factor in melanoma. Recently, visible (blue) light has also been described to induce skin pigmentation, without any obvious pro-carcinogenic effect. Studies have been carried out to identify genes induced by UV in melanocytes and to understand the mechanisms responsible for photo-induced skin pigmentation. However, the rarity of these cells in the epidermis (3% of cells) has so far been an insurmountable obstacle to achieving this goal. The same is true for visible light, for which the data is even more patchy. The advent of transcriptome analysis techniques at the single cell or single nucleus level will allow us to overcome this obstacle and identify the transcriptional effects of UV and blue light in melanocytes in-situ, as well as in other skin cells (keratinocytes, fibroblasts). Understanding the molecular mechanisms regulated by UV and blue light in melanocytes and other cells will reveal new key steps in skin pigmentation. The data from our study will be used to develop new photoprotective agents as well as new treatments for pigmentary pathologies. Primary objective Describe the variations in gene expression induced by solar ultraviolet (UV) radiation or blue light in human melanocytes in vivo. Secondary objectives Describe the variations in gene expression induced by ultraviolet (UV) radiation sunlight or blue light in other skin cells. Evaluation criteria Single cell transcriptome analysis Immunolabelling on skin sections Population and number of inclusions Healthy male volunteers, phototype III on the Fitzpatrick scale, age 25 + 5 years and of similar corpulence (body mass index between 20 and 28). 2 inclusions Duration of the study Total duration of the study: 12 months Duration of the inclusion phase: 1 month Duration of participation for a patient: 11 days Methodology Two healthy volunteers will be exposed to UV or visible light in the forearm region. Suction blisters, and skin biopsies will be performed in the test areas, suction bubbles for transcriptome, biopsies for immunohistochemistry. The study of gene expression in the different cell types will be done by RNA-Seq on single cells, using the 10X genomics approach. Finally a validation of the results will be carried out by immunostaining with specific antibodies or RNA-Scope. Course of the study - Day 1: The study begins with the determination of the Minimum Erythemal Dose (MED) for each subject in the region of the forearms. This determination will be carried out by means of the administration of six different doses in increasing stages of 25% of UVB + UVA rays (simulated solar ultraviolet spectrum) on six selected test areas (each 1.3 cm²). Exposed areas will be assessed 24 + 2 hours after exposure on Day 2, erythema will be assessed Day 2: Reading of the DEM, and irradiations on two zones in the region of the forearms with respectively a dose of 2 DEM UV, and 48J/cm2 in visible light. A third non-irradiated area will serve as a control. Day 3: A skin blister and biopsy will be performed on each of the three test areas. Cells collected in the blister fluid will be used for the transcriptome and biopsies for validation by immunohistochemistry. Day 11: The subjects will be seen again eight days after the day of sampling, i.e. on Day 11 for removal of sutures and monitoring of healing. On the same day, an evaluation of the level of UV pigmentation induced on each test area will be carried out visually and by colorimetry.
