Real life outcome analysis of breast cancer brain metastases treated with Trastuzumab Deruxtecan.

Tumor dissemination to the central nervous system (CNS) is almost a rule in the treatment journey of advanced HER2+ breast cancer (BC). Recent results demonstrated high intracranial efficacy with Trastuzumab Deruxtecan (T-DXd). However, a real-world evidence is lacking in literature.

Intra-mesenteric steroids for steroid-refractory graft-versus-host disease in pediatric patients: A safe option.

Introduction: Graft-versus-host disease is a serious complication after hematopoietic stem cell transplantation and is a major cause of death post-transplantation. Approximately 50% of acute graft-versus-host disease patients do not respond to systemic steroids and their prognosis is poor regardless of the treatment. This study describes our experience with pediatric patients diagnosed with steroid-refractory graft-versus-host disease who received intra-mesenteric steroid treatment.

A hidden enemy: Understanding the hemophagocytic syndrome in children under five years of age in a high-complexity institution in southwestern Colombia.

Introduction. Hemophagocytic syndrome is an under-recognized condition with high mortality in the pediatric population. It is characterized by excessive activation of immune cells and cytokine release, leading to persistent inflammation.

Non-cystic fibrosis bronchiectasis in pediatrics: A cohort profile of patients with inborn errors of immunity at a referral center in Cali, Colombia.

Introduction. Inborn errors of immunity are frequently associated with bronchiectasis. The diagnostic performance of these inborn errors has improved because the association of some of these entities with progressive airway damage is better known.

Haploidentical hematopoietic stem cell transplantation using post-transplant cyclophosphamide in patients with inborn errors of immunity: Experience in a reference center in Colombia.

Introduction: Inborn errors of immunity is a diverse group of rare diseases caused by over 400 genetic mutations affecting the immune system and increasing infection susceptibility, autoimmunity, and malignancy. Hematopoietic stem cell transplantation offers a curative option for some inborn errors of immunity, with haploidentical donors providing a viable alternative when identical donors are unavailable.

Objective: To determine survival, usefulness of weekly chimerism monitoring, immune reconstitution, and complications in patients with inborn errors of immunity who underwent haploidentical hematopoietic stem cell transplantation at a reference center in Colombia.
