Rapid Response To Sirolimus In Patients With Pik3ca-Related Overgrowth Spectrum, Jessica R Nye, Jackson C Green, Michael Talanker, Jose Barrera, Kate Richardson, Neethu M Menon, Adelaide A Hebert, Matthew R Greives, Autumn A Atkinson

Faculty, Staff and Student Publications

PIK3CA-related overgrowth spectrum (PROS) is an umbrella term used to unify a heterogenous group of vascular overgrowth disorders by a shared genetic cause. Given that patients with PROS have a known, or likely, gene mutation in the PI3K/AKT/mTOR cascade, we hypothesize they experience a rapid response to inhibitors of this pathway, including sirolimus. In the following case series, we describe 3 patients with PROS and their response to sirolimus therapy. Despite their unique clinical presentations, insight into the genetic origin of their vascular overgrowth allowed for their successful treatment with the same medication.

PURPOSE: Improving the treatment of psoriasis is a serious challenge today. Psoriasis is an immune-mediated skin condition affecting 125 million people worldwide. It is commonly treated with cyclosporine-A (CsA) and dithranol (DTH). CsA suppresses the activation of T-cells, immune cells involved in forming psoriatic lesions. Meanwhile, DTH is a potent anti-inflammatory and anti-proliferative drug that effectively reduces the severity of psoriasis symptoms such as redness, scaling, and skin thickness. CsA and DTH belong to BCS class II with limited oral bioavailability. We aim to develop a drug delivery system for topical co-delivery of CsA and DTH, exploring its therapeutic potential. …
