Аннотация
AIM: The present study aims to describe the phenotypic features of patients with hereditary haemorrhagic telangiectasia (HHT) seen at Royal Melbourne Hospital, Victoria, Australia, and to customise a protocol for surveillance of patients with HHT.
METHODS: This is a retrospective study in a tertiary referral hospital of all patients referred to the Clinical Genetics Service between 2007 and 2011 with a suspected diagnosis of HHT. Data abstracted from patient clinical records were analysed for clinical features, types of HHT and genetic testing results where available.
RESULTS: Our cohort comprising 40 females and 23 males patients was assessed using the Curacao criteria. Twenty-two patients fulfilled the criteria for a definite diagnosis, 30 had a possible diagnosis, and 11 patients were assessed as unlikely to have HHT at the time of data analysis. Seventeen patients had pulmonary arteriovenous malformations (AVM), five had cerebral AVM, five had hepatic AVM, three had confirmed bowel telangiectasia, and one patient had a pancreatic AVM. Two female patients with HHT had complicated pregnancies during their follow up with us. Three families had mutations in the endoglin (ENG gene), three had mutations in the ACVRL1 gene, and two families had mutations in the SMAD4 gene.
CONCLUSION: HHT is a multisystemic disorder and needs involvement of a team with experience in managing patients with HHT.
