T cell dysfunction is often present, and lymphoproliferative and autoimmune disorders as well as haematological cytopenias are frequently observed. In this study, we report a polyclonal expansion of large granular lymphocytes (LGL) in a substantial proportion of CVID patients, associated with splenomegaly, increased numbers of CD8+ T cells, inverted CD4\u2003:\u2003CD8 T cell ratios and neutropenia. CVID patients who had both increased numbers of LGL and granulocytopenia had elevated levels of soluble Fas ligand (sFasL). Our observations indicate that CVID may be added to the list of inflammatory diseases associated with increased numbers of LGL. Furthermore, our findings suggest common pathogenic mechanisms of granulocytopenia in CVID and lymphoproliferative disease of granular lymphocytes.<\/jats:p>","DOI":"10.1111\/j.1365-2249.2006.03086.x","type":"journal-article","created":{"date-parts":[[2006,4,29]],"date-time":"2006-04-29T03:22:04Z","timestamp":1146280924000},"page":"418-424","source":"Crossref","is-referenced-by-count":30,"title":["Polyclonal
