Active clinical trials for "Ichthyosis"

People with Xeroderma Pigmentosum (XP) have a genetic condition which stops their skin repairing damage from Ultraviolet Radiation (UVR). This means they are much more likely to develop potentially fatal skin cancers. The only way to reduce this damage is to rigorously protect the skin, by limiting UVR exposure. This done in a number of ways including: staying indoors; wearing protective clothing, sunscreen and glasses. People with XP can find it difficult to maintain this level of protection, putting themselves at risk. This research will test whether an intervention designed to enhance photoprotection activities is successful. It will use a randomised controlled trial design to compare the amount of UVR reaching the face, between participants receiving the intervention and those receiving standard clinical care. The amount of UVR reaching the face is important, as this is where people with XP develop most cancers. It is dependent on the overall level of exposure to UVR in the environment, and photoprotection used. The intervention involves a tailored conversation with the participant about their photoprotection practices. It will target both the overall exposure to UVR and the photoprotection used when outdoors, and will be conducted in 7 sessions with an intervention facilitator. The content will be dependent on the specific photoprotection behaviour being targeted (e.g., poor sunscreen application) and the reasons for poor photoprotection for each person. This could be low motivation related to doubts about the need to protect and concerns about protecting. Other barriers to protection might be lack of routines. The facilitator will provide information tailored to these beliefs and use other standard behaviour change techniques to encourage the development of "better" photoprotection habits. The investigators predict that the intervention group will have a lower mean daily dose of UVR to the face compared to the control group in two time periods in the summer months.

This phase Ib trial investigates the side effects of the combination of nivolumab and ipilimumab, and to see how well they work in treating patients with cancers that have come back (relapsed) or does not respond to treatment (refractory) and have an increased number of genetic changes. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Tumor mutational burden (TMB) is the total amount of genetic changes or "mutations" found in tumor cells. Some studies in adults with cancer have shown that patients with a higher TMB (an increased number of genetic changes) are more likely to respond to immunotherapy drugs. There is also evidence that nivolumab and ipilimumab can shrink or stabilize cancer in adult patients with cancer. This study is being done to help doctors learn if the combination of nivolumab and ipilimumab can help children, adolescents, and young adults patients live longer.

Lamellar ichthyosis (IL) is a rare autosomal recessive genodermatosis with a defect of keratinization of the skin which results in a severe generalized cutaneous xerosis with dark brown big scales, an ectropion, an eclabion, an alopecia and a palmo-plantar keratodermia. They are due to mutations of the gene TGM1 coding for the transglutaminase keratinocyte 1 (TG1) in 1/3 of the cases. Other genes were recently identified, ABCA12 coding for the triphosphate-binding adenosine cassette A12 and FLJ39501 which codes for a protein of the cytochrome p450 ( CYP4F2). No etiological treatment is available. Symptomatic treatment consists on twice application of emollients and keratolytic ointments which decrease the dryness of the skin and reduce scales. Oral isotretinoin is usually partially effective but is only suspensive and has numerous side effects. Recent studies showed that the epigallocatechin-3-gallate (POLYPHENON E®), extracted from green tea increases the differentiation of the normal human keratinocytes, as showedb by the increase of the involucrine, TG1 and caspase-14 genes expression. The main objective of this pilot study is to estimate the action and the tolerance of a daily application of topical Polyphénon E 10% ® to improve the desquamation and the cutaneous roughness of patients with lamellar ichthyosis, after 4 weeks of treatment. The secondary objectives To estimate the duration of remission obtained after the treatment To estimate the action of cutaneous Veregen® to improve the palmar and plantar involvement. To estimate the action of cutaneous Veregen on the pruritus And to estimate the global level of acceptability by the patient of the Veregen 10 %

This is an experimental non-randomized clinical study aimed at expanding the indications for the use of biological drugs with the aim of using them for the pathogenetic therapy of children with congenital ichthyosis.

A randomized double blinded clinical trial will be conducted comparing the effect of two simple basic moisturizers only different in the concentration of carbamide (urea). The concentrations of carbamide will be tested are 0 and 7.5, respectively. The study will be conducted as a split-body-study and will contain two arms randomized to comparing 0 and 7.5 % carbamide, respectively. Approximately 20 patients with at least clinically verified Ichthyosis Vulgaris will be enrolled to each study arm. The effect of the moisturizers will be assessed by clinical examination (score), patients assesment of effect and measurement of transepidermal water loss (TEWL) and other skin parameters.

The investigators' primary objective is to identify common and rare mutations in the filaggrin gene in African American patients with a diagnosis of atopic dermatitis and ichthyosis vulgaris. Atopic dermatitis, or eczema, is a common, chronic, relapsing and remitting problem in many children and affects 10-20% of the pediatric population. Itch is a predominant feature of this disease and is quite disruptive to daily activities of life. In addition to itch, it is characterized by markedly dry skin, small red bumps that may have fluid. Ichthyosis vulgaris is characterized by extremely dry, scaly skin with a fine white scale and increased amounts of lines noted on the palms. Filaggrin is a protein that is essential for the skin to function properly as a barrier and found to be mutated in some European patients with ichthyosis vulgaris and atopic dermatitis. This association has not been looked at in the African American population. Genomic DNA (gDNA) will be purified from buccal swabs using commercially available kits and analyzed.

Presence/absence of subclinical keratoconus with corneal topographic abnormalities (skewed radial axes for forme fruste keratoconus, and inferior steepening for keratoconus suspect) on axial specular topography (TMS-4 Tomey), and elevation topographies: Pentacam (Oculus) and Orbscan (Bausch & Lomb).

Study aim: To determine the effect of an intensified daily photoprotection over 24 months with an SPF30 sunscreen and an after sun-lotion both containing liposomal DNA repair enzymes in a population of patients at high-risk for skin cancer, including xeroderma pigmentosum (XP) and basal cell nevus syndrome.

RATIONALE: Patients with xeroderma pigmentosum are more likely to develop skin lesions in sun-affected areas. These skin lesions, such as actinic keratoses, can develop into skin cancer. T4N5 liposome lotion may reduce actinic keratoses or other sun-induced skin damage in patients with xeroderma pigmentosum. PURPOSE: Randomized double-blinded phase III trial to compare treatment using T4N5 liposome lotion with treatment using placebo in reducing actinic keratoses and other sun-induced skin damage in patients with xeroderma pigmentosum.

This is designated to validate patient-reported outcomes (PRO) measures in itch-specific pediatric skin conditions, such as atopic dermatitis, and examine the ability of a modified stigma instrument to assess the severity and type of stigma experienced in atopic dermatitis and other potentially stigmatizing conditions.
