Filter by:Cutaneous microcystic lymphatic malformations (CMLMs) are rare conditions of children and adults resulting from abnormal embryologic development of lymphatic vessels. They present as clusters of vesicles full of lymph and blood of various extent. They ooze and bleed, inducing maceration, esthetic impairment, scars, pain, bacterial infections and impaired quality of life. Currently, treatments for CMLMs are disappointing, and their management is challenging. Sirolimus is an inhibitor of mammalian target of rapamycin (mTOR), a serine/threonine protein kinase involved in cell growth and proliferation, cellular metabolism, autophagy and angio-lymphangiogenesis. Topical sirolimus, known to be efficient and well tolerated in cutaneous angiofibromas linked to tuberous sclerosis, has recently been reported effective in few reports of patients with CMLMs. The objective of this trial is to compare the efficacy and safety of a 12-week application of 0.1% topical sirolimus versus topical vehicle in CMLMs in children and adults.
Standard of care for Lymphatic Malformations has been surgical excision. We have been using OK432/Picibanil (generously supplied by Chugai Pharmaceuticals in Japan) since 1992 with great success for macrocystic disease. The objective of the study was to provide OK-432 immunotherapy to subjects with macrocystic or mixed (> 50% macrocystic) lymphatic malformations (LMs) and investigate the efficacy and safety of OK 432 as a treatment option in subjects with LMs.
The lymphatics regulate the interstitial fluid by removing excessive fluid. It represents an extremely important step in the prevention of edema. The Fontan-Kreutzer procedure has revolutionized the treatment of univentricular hearts. However, it is associated with severe complications such as protein-losing enteropathy (PLE) and peripheral edema that may involve the lymphatic circulation. Our hypothesis is that patients with a univentricular circulation have a reduced functionality of the lymphatic vasculature, which predisposes them to developing complications such as edema and PLE. The functional state of lymphatics is investigated using near infrared fluorescence imaging, NIRF. The anatomy is described using non-contrast MRI and the capillary filtration rate is measured using plethysmography.
To evaluate the efficacy of Rapamycin in extended cervicofacial lymphatic malformations in pediatric patients. Rapamycin is administered oral for a 6 month period. The success rate is determined by volume reduction superior to 1/5e of the initial volume measured by MRI, impact on QOL and reduction of bleeding in case of mucosal involvement.
Lymphatic anomalies are a rare subset of vascular anomalies that are poorly understood. the understanding of the natural history, long-term outcomes, risk factors for morbidity and mortality, and the relative benefit of medical therapies and procedures is limited.The goal of this project is to better understand these diseases and improve the care of theses rare patients. To do this, the investigators are conducting an observational study of patients with lymphatic anomalies, including an annual follow-up questionnaire to gather prospective data on mortality, morbidity, treatments, and functionality as well as quality of life.
A Phase 2 study to evaluate safety and efficacy of sildenafil taken orally to improve or resolve lymphatic malformations in children. Subjects may receive either placebo or treatment in an oral dosage with an open label extension for subjects who received placebo. The study treatment assignment will be randomized in a double blind fashion. MRI examination will evaluate change in lesion volume due to treatment. Other safety and efficacy measures will be taken through the 32-week study duration. Funding Source - FDA OOPD
There is an unsatisfied medical need for a first-line treatment of lymphatic malformations with a good benefit/risk profile. Based on a patient experience in the institution, the investigators plan to verify whether or not the medication sildenafil has a beneficial effect on lymphatic malformations. The investigators plan to do this by treating patients with lymphatic malformations with the medication sildenafil for a 20 week period. This is an investigator initiated study funded by an Innovations in Patient Care grant and a SPARK grant.
The investigators propose a pilot trial to obtain preliminary information regarding the safety and response rate of patients with symptomatic lymphatic malformations treated with oral Selenium. Information obtained in this pilot trial will be used to plan future phase 2 clinical trials. Hypotheses: - Selenium will be safe and efficacious in the treatment of adolescents and young adults with symptomatic lymphatic malformations - Disease response will correlate with serum levels of selenium and blood levels of antioxidants essential to selenium metabolism.
The purpose of this study is to determine if the use of sirolimus in the treatment of children and young adults with complicated vascular anomalies will prove to be safe and provide objective response resulting in improved clinical status and quality of life.

Controversy exists in the treatment of airway hemangiomas ranging from tracheotomy, various lasers, to open removal, none of which have proven to be a gold standard. Venous malformations of the airway are difficult to treat and also require laser therapy or open removal and often repeated treatments are required. Similarly airway lymphatic malformations can require multiple treatment modalities as well as multiple procedures and are infrequently eradicated when extensive. New uses for various lasers and differing treatment protocols are frequently developed. Review of the treatment modalities and efficacy of these methods is required. The goal of this research is to determine protocols for treatment of airway vascular malformation and to evaluate our results from treatment of these lesions.
