Recent decades have seen the discovery of new genes in the lymphopoiesis pathway, such as JAK\u2013STAT. This case series supplemented by a literature review aims to describe clinical and biological characteristics of patients with both CIVD and LGLL.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methodology<\/jats:title><jats:p>Patients were included through a call for comments to French and Belgian centers and through a literature review via PubMed. Clinical characteristics were compared to two large French cohort involving CVID and LGLL patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twelve patients were included. In all cases, CVID precedes LLGL (median diagnosis delay for LLGL was 7\u2009years). Most cases presented with splenomegaly and autoimmune cytopenia. Ten out of 12 patients underwent splenectomy during follow up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Patients with LGLL and CVID differ from patients without immune deficiency in term of clinical presentation and prognosis. We suggest CVID may act as a trigger of LGL lymphocytosis, due to endogenous and exogenous antigenic pressure leading to the selection of a dominant LGL clone and stimulation of the JAK\u2013STAT pathway. The role of splenomegaly and splenectomy in LGLL onset warrant further investigation in future studies.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ejh.14265","type":"journal-article","created":{"date-parts":[[2024,7,11]],"date-time":"2024-07-11T06:29:42Z","timestamp":1720679382000},"page":"550-557","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Characteristics of large granular lymphocyte leukemia associated with variable common immunodeficiency disorders: A study of 12 cases"],"prefix":"10.1111","volume":"113","author":[{"given":"C.","family":"Gueuning","sequence":"first","affiliation":[{"name":"Internal Medicine and Infectious diseases, H\u00f4pital Haut\u2010L\u00e9v\u00eaque  Pessac France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Lazaro","sequence":"additional","affiliation":[{"name":"Internal Medicine and Infectious diseases, H\u00f4pital Haut\u2010L\u00e9v\u00eaque  Pessac France"},{"name":"Universit\u00e9 de Bordeaux  Bordeaux France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Dupuy","sequence":"additional","affiliation":[{"name":"Internal Medicine and Infectious diseases, H\u00f4pital Haut\u2010L\u00e9v\u00eaque  Pessac France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Leonard","sequence":"additional","affiliation":[{"name":"Internal Medicine and Infectious diseases, H\u00f4pital Haut\u2010L\u00e9v\u00eaque  Pessac France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Greib","sequence":"additional","affiliation":[{"name":"Internal Medicine and Infectious diseases, H\u00f4pital Haut\u2010L\u00e9v\u00eaque  Pessac France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Prot\u2010Leurent","sequence":"additional","affiliation":[{"name":"Internal Medicine and Infectious diseases, H\u00f4pital Haut\u2010L\u00e9v\u00eaque  Pessac France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Riviere","sequence":"additional","affiliation":[{"name":"Internal Medicine and Infectious diseases, H\u00f4pital Haut\u2010L\u00e9v\u00eaque  Pessac France"},{"name":"Universit\u00e9 de Bordeaux  Bordeaux France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
