Minimal Hepatic Encephalopathy in Hereditary Hemorrhagic Telangiectasian

Italy50 participantsStarted 2018-01-08

Plain-language summary

HHT or Rendu-Osler-Weber disease is a genetic disease with an autosomal dominant inheritance pattern, characterized by widespread telangiectases that can involve several organs including the intestinal tract and the liver. Liver involvement by HHT is characterized by widespread diffuse liver vascular malformations that give origin to arteriovenous, arterioportal and portovenous shunts. The prevalence of hepatic involvement in HHT can reach 78%. Less commonly, patients may also develop porto-systemic encephalopathy (PSE). However, there are no studies on the possibility that patients with HHT might develop mHE, a highly plausible hypothesis considering the presence of diffuse macroscopic and microscopic porto-systemic shunt in this pathological condition.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * In this study all patients with hereditary hemorragic telangectasia carrying micro or macro porto-systemic vascular shunts will be enrolled. Exclusion Criteria: * Actual or previous presence of overt HE (West-Haven criteria) (1,2), gastrointestinal bleeding in the previous 2 weeks, significant comorbidities such as cardiac, respiratory or renal failure; previous transjugular intrahepatic portosystemic shunt, electrolyte imbalance as hyponatremia (Na\<125 mg/dl), neurological diseases, color blindness or severe visual disturbances (cataracts, diabetic retinopathy), hepatocellular carcinoma or other malignancies, use of psychotropic drugs in the week prior to the study. Patients with advanced liver disease will also be excluded. Diagnosis of cirrhosis or advanced liver fibrosis will be based on: a) histological evaluation documented at any time before enrollment, b) liver transient elastography and c) a combination of clinical, laboratory and abdominal ultrasound parameters established a priori (Barone M et al. Digestive and Liver Disease 2018;50:496-500).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
