In a large clinical trial, bevacizumab infusion was associated with a decrease in cardiac output and reduced duration and number of episodes of epistaxis in treated HHT patients. Thalidomide, another anti-angiogenesis drug, was also reported to have beneficial effects in HHT patients. Thalidomide treatment was found to induce vessel maturation in an experimental mouse model of HHT and to reduce the severity and frequency of nosebleeds in the majority of a small group of HHT patients. The blood hemoglobin levels of these treated patients rose as a result of reduced hemorrhage and enhanced blood vessel stabilization. Epidemiology
Population studies from numerous areas in the world have shown that HHT occurs at roughly the same rate in almost all populations: somewhere around 1 in 5000. In some areas, it is much more common; for instance, in the French region of Haut Jura the rate is 1:2351 - twice as common as in other populations. This has been attributed to a founder effect, in which a population descending from a small number of ancestors has a high rate of a particular genetic trait because one of these ancestors harbored this trait. In Haut Jura, this has been shown to be the result of a particular ACVRL1 mutation (named c.1112dupG or c.1112_1113insG). The highest rate of HHT is 1:1331, reported in Bonaire and Curaçao, two islands in the Caribbean belonging to the Netherlands Antilles.Most people with HHT have a normal lifespan. The skin lesions and nosebleeds tend to develop during childhood.
