Brief Summary:
This study will determine if medical treatment of colitis inflammation of the colon resulting in loose bowel movements rectal bleeding and belly pain that is used for other colitis conditions such as Crohns disease and ulcerative colitis is safe and effective for treating colitis in patients with Hermansky-Pudlak syndrome HPS HPS is a hereditary disorder that causes albinism visual impairment and abnormal bleeding Some patients also develop colitis pulmonary fibrosis and kidney disease
Patients with HPS and colitis who are 18 years of age or older may be eligible for this study Participants receive treatment for their colitis symptoms with one or more of several study drugs which include mesalamine 5-ASA corticosteroids infliximab and 6-mercaptopurine adalimumab and tacrolimus The drugs are added to the treatment plan one at a time to find the combination that works best for the individual patient Patients who respond to one or more of the medications may continue treatment with that same combination for up to 6 months
Regular clinic visits are scheduled for blood tests symptoms ratings questionnaires and periodic physical examinations and colonoscopies to measure the response to treatment and evaluate any side effects

Detailed Description:
The primary purpose of this study is to detect patterns of immune abnormalities in the colitis associated with Hermansky-Pudlak Syndrome HPS Additionally we aim to document the clinical response to and tolerance of conventional inflammatory bowel disease IBD therapy for HPS patients with active colitis associated with Hermansky-Pudlak Syndrome HPS HPS is a rare autosomal recessive disorder causing dysfunctional lysosome-related organelle formation and trafficking resulting in oculocutaneous albinism and a bleeding diathesis secondary to platelet dysfunction Associated conditions include pulmonary fibrosis IBD and systemic ceroid deposition The associated IBD has been reported to occur at a higher frequency in the HPS-1 and HPS-4 subtypes compared to the prevalence of IBD in non-HPS populations HPS IBD has clinical features of both ulcerative colitis UC and Crohns disease but histologically resembles Crohns disease in that granulomas are commonly seen in the mucosa of the intestine The pathogenesis of HPS IBD is not fully understood and little data beyond descriptions of the clinical and histologic manifestations have been published Furthermore reports on treatment of the colitis in HPS patients are largely anecdotal and our own experience suggests that many patients may be under-treated
HPS patients with active colitis will be enrolled into this prospective treatment study Endpoints for the immunopathogenesis studies will include baseline measurements of and changes in immune cell populations cytokine and chemokine expression In the blood and gut mucosa Endpoints for the study of response to treatment will include changes in clinical endoscopic and histologic scores as well as the rate and severity of adverse events Descriptive summary statistical analysis n mean median standard deviation minimum and maximum range and simple correlations of clinical response variables with immune parameters will be done
