Article Synopsis
  • Allogeneic haematopoietic stem cell transplantation (alloHSCT) shows high survival rates (90% overall survival) in adolescents and adults with severe inborn errors of immunity (IEI), as assessed in a study of 82 patients.
  • The study found that pre-transplant immune dysregulation (measured by the IDDA v2.1 score) and the haematopoietic cell transplantation comorbidity index (HCT-CI) score significantly affected transplant outcomes, including overall survival and event-free survival.
  • Notably, a portion of patients with a high IDDA v2.1 score and low HCT-CI score indicates that existing risk assessments may underestimate the risks of alloHSCT, highlighting

Dominant negative variants in ITPR3 impair T cell Ca2+ dynamics causing combined immunodeficiency.

J Exp Med

January 2025

Molecular and Cellular Immunology, Great Ormond Street Institute of Child Health, University College London, London, UK.

The importance of calcium (Ca2+) as a second messenger in T cell signaling is exemplified by genetic deficiencies of STIM1 and ORAI1, which abolish store-operated Ca2+ entry (SOCE) resulting in combined immunodeficiency (CID). We report five unrelated patients with de novo missense variants in ITPR3, encoding a subunit of the inositol 1,4,5-trisphosphate receptor (IP3R), which forms a Ca2+ channel in the endoplasmic reticulum (ER) membrane responsible for the release of ER Ca2+ required to trigger SOCE, and for Ca2+ transfer to other organelles. The patients presented with CID, abnormal T cell Ca2+ homeostasis, incompletely penetrant ectodermal dysplasia, and multisystem disease.

Fabry disease (FD) is an X-linked lysosomal storage disease caused by pathogenic variants in the GLA gene. It has a wide range of clinical manifestations, typically related to the specific underlying GLA variant. One of the main features of FD is kidney involvement; therefore, several studies have addressed the prevalence of FD in all types of patients with chronic kidney disease.

Protein kinases: drug targets for immunological disorders.

Nat Rev Immunol

December 2023

Molecular Immunology and Inflammation Branch, National Institute of Arthritis and Musculoskeletal and Skin Diseases, National Institutes of Health, Bethesda, MD, USA.

Protein kinases play a major role in cellular activation processes, including signal transduction by diverse immunoreceptors. Given their roles in cell growth and death and in the production of inflammatory mediators, targeting kinases has proven to be an effective treatment strategy, initially as anticancer therapies, but shortly thereafter in immune-mediated diseases. Herein, we provide an overview of the status of small molecule inhibitors specifically generated to target protein kinases relevant to immune cell function, with an emphasis on those approved for the treatment of immune-mediated diseases.

Heterozygous mutations in result in an inborn error of immunity with an autoimmune and frequently severe clinical phenotype. Autologous T cell gene therapy may offer a cure without the immunological complications of allogeneic hematopoietic stem cell transplantation. Here, we designed a homology-directed repair (HDR) gene editing strategy that inserts the cDNA into the first intron of the genomic locus in primary human T cells.

Purpose: Allogeneic hematopoietic stem cell transplant (HSCT) remains the treatment of choice for patients with inborn errors of immunity (IEI). There is little published medical outcome data assessing late medical complications following transition to adult care. We sought to document event-free survival (EFS) in transplanted IEI patients reaching adulthood and describe common late-onset medical complications and factors influencing EFS.

Introduction: Obesity is a chronic disease, which has significant health consequences and is a staggering burden to health care systems. Obesity can have harmful effects on the cardiovascular system, including heart failure, hypertension, coronary heart disease, and atrial fibrillation (AF). One of the possible substrates might be epicardial adipose tissue (EAT), which can be the link between AF and obesity.

Allogeneic hematopoietic stem cell transplantation (HSCT) is the gold standard curative therapy for infants and children with many inborn errors of immunity (IEI), but adolescents and adults with IEI are rarely referred for transplant. Lack of published HSCT outcome data outside small, single-center studies and perceived high risk of transplant-related mortality have delayed the adoption of HSCT for IEI patients presenting or developing significant organ damage later in life. This large retrospective, multicenter HSCT outcome study reports on 329 IEI patients (age range, 15-62.

How I use allogeneic HSCT for adults with inborn errors of immunity.

Blood

November 2021

Institute of Immunity & Transplantation, University College London, London, United Kingdom.

Inborn errors of immunity (IEIs) are rare inherited disorders arising from monogenic germline mutations in genes that regulate the immune system. The majority of IEI are primary immunodeficiencies characterized by severe infection often associated with autoimmunity, autoinflammation, and/or malignancy. Allogeneic hematopoietic stem cell transplant (HSCT) has been the corrective treatment of choice for many IEIs presenting with severe disease in early childhood, and experience has made this a successful and comparatively safe treatment in affected children.

Article Synopsis
  • Haematology patients undergoing chemotherapy or immunotherapy face higher risks for severe COVID-19 outcomes, prompting a study on risk factors and treatment complications in 55 such patients.
  • Among the patients, 82% were receiving systemic anti-cancer therapy at COVID-19 diagnosis, with 37% of hospitalized patients succumbing to the virus, but all outpatients recovered.
  • Key findings suggest that while SACT should be continued in urgent cases despite COVID-19, treatment modifications may be needed on a case-by-case basis, highlighting the need for further studies in larger cohorts to refine treatment strategies.

Allogeneic HSCT in Adolescents and Young Adults With Primary Immunodeficiencies.

Front Pediatr

October 2019

Department of Pediatrics, Dr. von Hauner Children's Hospital, University Hospital, LMU Munich, Munich, Germany.

Significant advances in hematopoietic transplantation over the past 20 years, have facilitated the safe transplantation of older adults with higher co-morbidities. In pediatric practice these advances have simultaneously improved outcomes for sicker children with complex, rare diseases including the primary immunodeficiencies, PID. With more widespread adoption of genetic sequencing, older patients with disease-causing mutations restricted to the hematopoietic system can be identified who may benefit from allogeneic hematopoietic stem cell transplantation (Allo-HSCT).

Objectives: To establish the incidence of obstetric neonatal brachial plexus and facial nerve injuries in a tertiary maternity hospital in the United Kingdom and to identify associated risk factors with an emphasis on the time of delivery.

Study Design: From our hospital electronic data bases we identified all live births born between 2000 and 2016 and those neonates who sustained a nerve injury during delivery. We performed a logistic regression analysis linking "facial nerve injury" and "brachial plexus injury" with variables for which we had complete cohort data including "breech", "gestation", "sex", "birthweight", "day of week", "time of delivery", "method of delivery", "singleton/multiple deliveries" and "number of deliveries per day".

Ocular features of Gaucher disease include gaze abnormalities, corneal clouding, ocular deposits and pigmentary changes in the macula. We report the presence of bilateral fovea sparing macular deposits in a 21-year-old woman with type 3 Gaucher disease. Macular deposits occur due to glucocerebroside accumulation within histiocytes and retinal deposits might correlate with the degree of systemic infiltration.
