Estrogen-progesterone therapy for bleeding gastrointestinal telangiectasias in chronic renal failure. An uncontrolled trial

Gastrointestinal telangiectasias cause hemorrhage in patients with chronic renal failure. Therapies using vasoconstrictors, endoscopic application of heat, and surgery have had limited efficacy. Because several reports have suggested that estrogen or estrogen-progesterone therapy may control mucosal bleeding from telangiectasias in patients with hereditary hemorrhagic telangiectasia, we treated seven patientss with chronic renal failure and bleeding gastrointestinal telangiectasias with systemic estrogen or estrogen-progesterone in an uncontrolled trial. Bleeding ceased in all patients. Blood transfusion requirements decreased from a mean of 1.2 U/month before treatment to 0.21 U/month after treatment. No significant side effects were noted. Results of this trial indicate the need for controlled investigations of this type of hormonal therapy.
