Introduction |
|---|
Hereditary haemorrhagic telangiectasia (HHT, Rendu-Osler-Weber
syndrome) exemplifies an important group of diseases which have
catalysed advances in the understanding of fundamental
pathophysiological mechanisms. In this paper areas of clinical
management of HHT are discussed and the molecular pathogenesis is
reviewed. The first section is aimed at all clinicians and concentrates
on the recognition of a disorder in which silent cerebral and pulmonary involvement may be life threatening if left untreated. Recent data
concerning the diagnostic and treatment modalities for pulmonary arteriovenous malformations (PAVMs) are also reviewed, and the growing
concern that many patients with HHT may have small or residual PAVMs is
highlighted. The paucity of good longitudinal data on these patients
and others with different forms of HHT highlights the need for further
clinical studies. In the second section the results of molecular
research which suggests a role for receptors and ligands of the
transforming growth factor (TGF)-
superfamily
