Gut microbial alteration in chronic spontaneous urticaria unresponsive to second generation antihistamines and its correlation with disease characteristics- a cross-sectional case-control study.

Background: Gut microbial involvement has been speculated in chronic spontaneous urticaria (CSU). The aim of the study was to compare the gut microbiome composition and diversity in CSU patients uncontrolled with second-generation antihistamines (sgAHs) and healthy individuals, as well as to explore any association between gut microbiome and disease characteristics.

Methods: A cross-sectional case-control study including 20 CSU patients unresponsive to standard doses of sgAHs, and 15 age-and-sex matched healthy controls was conducted.

Haematopoietic gene therapy of non-conditioned patients with Fanconi anaemia-A: results from open-label phase 1/2 (FANCOLEN-1) and long-term clinical trials.

Background: Allogeneic haematopoietic stem-cell transplantation is the standard treatment for bone marrow failure (BMF) in patients with Fanconi anaemia, but transplantation-associated complications such as an increased incidence of subsequent cancer are frequent. The aim of this study was to evaluate the safety and efficacy of the infusion of autologous gene-corrected haematopoietic stem cells as an alternative therapy for these patients.

Methods: This was an open-label, investigator-initiated phase 1/2 clinical trial (FANCOLEN-1) and long-term follow-up trial (up to 7 years post-treatment) in Spain.
