Lipopolysaccharide responsive beige-like anchor protein (LRBA) deficiency is a primary immunodeficiency disorder (PID) that can cause a common variable immunodeficiency (CVID)-like disease. The typical features of the disease are autoimmunity, chronic diarrhea, and hypogammaglobulinemia. Neurological complications are also reported in patients affected by LRBA deficiency. We describe a 7-year old female with an acute cervical longitudinally extensive transverse myelitis (LETM) as a feature of LRBA deficiency. This is the first case of LETM associated with LRBA deficiency described in literature.

Inborn errors of immunity (IEI) are rare diseases that affect the immune system. According to the latest International Union of Immunological Societies (IUIS) classification, 485 different IEI have been identified. Even if increased susceptibility to infections is the best-known symptom, IEI are no longer defined by the higher likelihood of infections alone.

Deleterious mutations in the lipopolysaccharide responsive beige-like anchor protein (LRBA) gene cause severe childhood immune dysregulation. The complexity of the symptoms involving multiple organs and the broad range of unpredictable clinical manifestations of LRBA deficiency complicate the choice of therapeutic interventions. Although LRBA has been linked to Rab11-dependent trafficking of the immune checkpoint protein CTLA-4, its precise cellular role remains elusive.

Article Synopsis
  • The study focuses on a case involving a 49-year-old woman diagnosed with rheumatoid arthritis and subsequent severe immune deficiency due to a homozygous mutation in the LRBA gene, which is crucial for immune regulation.
  • The patient showed various symptoms, including massive splenomegaly, portal hypertension, and a rare type of cystitis associated with mast cells, indicating a complex clinical presentation.
  • This case emphasizes the importance of understanding LRBA's role in immune function and the diverse clinical manifestations linked to its deficiency.

LRBA deficiency is an inborn error of immunity defined by autoimmunity, lymphoproliferation, recurrent infections, cytopenia, and inflammatory bowel disease. Despite recent advances in managing this disease with targeted biologic therapy, haematopoietic stem cell transplant (HSCT) remains the only cure. However, great variability exists between protocols used to transplant patients with LRBA deficiency.

Homozygous mutations in the lipopolysaccharide-responsive vesicle trafficking, beach- and anchor-containing () gene lead to a syndrome characterized by early-onset hypogammaglobulinemia, autoimmunity, lymphoproliferation, and inflammatory bowel disease. This report describes a 10-year-old female who experienced three seizure episodes, including two generalized tonic-clonic seizures (GTCS) and one focal seizure, alongside septic shock. The patient had a history of recurrent respiratory tract infections, inflammatory bowel disease, multiple blood transfusions, lymphadenopathy, significant organomegaly, and hematological abnormalities, all consistent with an deficiency.
