Official title
The Immune Signature of Palmoplantar Pustulosis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is being done to learn more about a less common "type" of psoriasis, called palmoplantar pustulosis (PPP). The majority of the current treatments used for this type of psoriasis have only a moderate effect on PPP. Thus, the investigators believe that PPP may be a different disease entity altogether, requiring different therapies. As such, the investigators hope to discover an immune signature for this condition. An immune "signature" is the unique way in which the combination of genes, cells, and proteins of the immune system work for each person. Because both psoriasis and the type of psoriasis patients have been diagnosed with, PPP, are conditions of abnormal immune system function, it is important to understand the overall function of the immune system in this condition (that is, find the immune "signature"). This study should help identify an immune system "signature" in people with PPP. The investigators have a laboratory technology which allows them to read the genetic "signatures" of a person's blood cells. Genes contain the instructions for making living things. Genes are contained in the cells' DNA (deoxyribonucleic acid). Most DNA is the same among humans, but the small differences people have in their DNA may explain why people develop different diseases. DNA and the genes it contains help produce RNA (ribonucleic acid), which in turn helps make proteins in people's cells. Differences in the types of proteins and the amount of those different proteins people's cells produce can affect a person's immune system. To help the investigators determine the immune "signature" in PPP, they will be examining the different genes, cells, and proteins that are active in patients with PPP versus patients who do not have the condition. The investigators will examine these genes, cells, and proteins in skin (through a skin sample) and in blood (through a blood draw). The goal is to develop new treatments for this skin condition. To do this, the investigators need to compare the skin and blood of patients with this particular type of psoriasis to the samples of healthy patients.
