Ichthyosis Clinical Trials

There is emerging evidence that alterations in bile acids and SCFA associated with IBS could be associated with changes in the gut microbiota. In addition to modulating levels of intraluminal organic acids, it has been hypothesized that gut microbiota may alter local immune responses, modulate visceral pain responses, and impair ...

This study involves a series of research and development projects targeted at two of the most common chronic diseases affecting children: asthma and atopic dermatitis (AD, or eczema). The Investigators propose to directly validate patient-reported outcomes (PRO) measures in a large cohort of itch-specific pediatric skin conditions, with a primary ...

Background: Hereditary ichthyosis are rare genetic diseases characterized by an abnormal epithelial keratinization due to mutations in gene involved in skin barrier. Patients present with scales on the whole body. Recent classification basically distinguishes syndromic from non-syndromic forms. Ichthyoses are severe diseases with significant impact on quality of life, due ...

Netherton Syndrome is a serious skin disorder caused by damage in a gene called SPINK5. This gene controls the formation of a protein called LEKTI, which important for skin barrier function. LEKTI inhibits certain enzymes (serine proteinases) in the outermost layer of the skin (epidermis). The function of the serine ...

This project will test the effectiveness of an integrative medicine approach in treating irritable bowel syndrome (IBS). Over the course of 18 months, we will recruit 85 participants with IBS in New York City. These participants will be randomized to either a 4-week group-oriented treatment intervention incorporating a low FODMAP ...

This study will assess dynamic effects of two major antigens on the duodenal mucosa by confocal laser endomicroscopy (CLE). Patients will be blinded to the antigens used (wheat, yeast). Following CLE it is planned to have a cross over exclusion diet with/without the antigens including a washout phase. Furthermore, patients ...

Rectal biopsies from IBS patients or healthy subjects will be taken. Biopsies will be used for: the isolation of submucosal plexus to perform: 1.1 live nerve recordings and Calcium imaging; 1.2 immunohistochemistry; 1.3 mRNA (Messenger ribonucleic acids) isolation and real time PCR (Polymerase chain reaction); culturing biopsies On the basis ...

The investigators hypothesize that early complications and comorbidities in infants with congenital ichthyosis are genotype-dependent, such that clinical standards of care can be tailored to the genetic diagnoses. Definition of clinical groups based upon phenotype may also provide useful predictors of outcome. Information gained from this study will provide the ...

Four rare genetic diseases, xeroderma pigmentosum (XP), Cockayne syndrome (CS), the XP/CS complex and trichothiodystrophy (TTD) have defective DNA excision repair although only XP has increased cancer susceptibility. We plan to perform careful clinical examination of selected patients with XP, XP/CS, CS, TTD, XP/TTD and other overlap syndromes to follow ...
