Onset of systemic arterial hypertension after initiation of elexacaftor/tezacaftor/ivacaftor in adults with cystic fibrosis: A case series.

Elexacaftor/tezacaftor/ivacaftor (ETI) is associated with major improvements in respiratory outcomes of individuals with cystic fibrosis (CF) and at least one Phe508del mutation. Although ETI was well tolerated in registration studies, the attention on adverse events not previously described is very high in the post-marketing phase. In this case series we report the onset of systemic arterial hypertension in 4 individuals with CF within the first weeks of starting therapy. All patients needed cardiac evaluation and started chronic anti-hypertensive therapy. Until more data is available, this report could foster the attention of CF physicians towards careful monitoring of cardiovascular parameters in patients starting ETI.
