Pituitary stalk interruption syndrome (PSIS) is a particular entity in the population of patients with hypopituitarism. Only rare cases have a known genetic cause.
i) To compare subgroups with or without extra-pituitary malformations (EPM) in a cohort of PSIS patients to identify predictive factors of evolution, ii) to determine the incidence of mutations of the known pituitary transcription factor genes in PSIS.
We analyzed features of 83 PSIS patients from 80 pedigrees and screened HESX1, LHX4, OTX2, and SOX3 genes.
PSIS had a male predominance and was rarely familial (5%). Pituitary hypoplasia was observed only in the group with EPM. Multiple hormone deficits were observed significantly more often with versus without EPM (87.5 vs 69.5% respectively). Posterior pituitary location along the stalk was a significant protective factor regarding severity of hormonal phenotype. A novel HESX1 causative mutation was found in a consanguineous family, and two LHX4 mutations were present in familial PSIS.
PSIS patients with EPM had a more severe hormonal disorder and pituitary imaging status, suggesting an antenatal origin. HESX1 or LHX4 mutations accounted for <5% of cases and were found in consanguineous or familial cases.

The low prevalence of pituitary diseases makes patient autonomy crucial, and self-management programs should be more common.
To assess the efficacy of an education program for patients with pituitary diseases in terms of patients’ quality of life, satisfaction and goal attainment.
Design and methods
Adult patients with pituitary disorders were recruited in a tertiary referral center and chose at least three of eight possible sessions on various topics, from disease management to psychosocial issues. Patients were included if they attended at least three sessions between 2012 and 2016 and completed the initial, final, and follow-up questionnaires. Data on quality of life (SF36), satisfaction and goal attainment were analyzed.
Fifty-three patients were included (33 women; mean age, 53.5 years). There were a significant quality of life improvements in terms of physical and psychic limitation scores at the final assessment that persisted at follow-up evaluation. Most patients reached their objectives, especially those on sharing experiences and improving autonomy and self-confidence. More than half set new objectives at the end of the program, the most popular one being to reinforce their knowledge of their pituitary disease, its evolution and treatment (17.1% of patients). The mean overall satisfaction score was 3.75/4. At follow-up evaluation, patients reported improved self-management of pituitary disease (3.6/5) and improved self-efficacy (3.8/5).
Individualizing the educational objectives of patients with pituitary disease improves the way they live with their disease. If confirmed in other cohorts, this approach could become the gold standard for education programs in rare endocrine diseases.
