In a group of 6 children (age range 4\u201315 years; mean age 8.5 years) with portal hypertension, we examined peripheral blood mononuclear leukocytes for possible changes in their proportions, numbers and function. Compared to normal subjects, children with portal hypertension had a marked reduction in the percentages and absolute numbers of T lymphocytes (CD3+), T \u2018helper\/inducer\u2019 (CD4+) and T \u2018suppressor\/cytotoxic\u2019 (CD8+) cells. However, the percentages of B lymphocytes (FMC1+), natural killer cells (Leu 11+) and monocytes (morphological) were increased, and the absolute numbers of B cells were significantly increased in these patients. Lymphocyte responsiveness to phytohemagglutinin, pokeweed mitogen and concanavalin A were depressed in the patients, while the natural killer cell cytotoxicity was slightly increased. Thus, children with portal hypertension show changes in the relative proportions and absolute numbers of peripheral blood mononuclear blood leukocyte subpopulations as well as changes in mononuclear leukocyte function.<\/jats:p>","DOI":"10.1159\/000234823","type":"journal-article","created":{"date-parts":[[2009,8,7]],"date-time":"2009-08-07T09:46:18Z","timestamp":1249638378000},"page":"348-352","source":"Crossref","is-referenced-by-count":4,"title":["Alterations in Function and Subpopulations of Peripheral Blood Mononuclear Leukocytes in Children with Portal Hypertension Leukocyte Subtypes and Function in Portal Hypertension"],"prefix":"10.1159","author":[{"given":"Antonio","family":"Ferrante","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Geoffrey P.","family":"Davidson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lorraine J.","family":"Beard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David H.B.","family":"Goh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,8,5]]},"container-title":["International Archives of Allergy and Applied Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/234823","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000234823","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T11:00:07Z","timestamp":1777633207000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000234823"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,8,5]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000234823","archive":["Portico"],"relation":{},"ISSN":["0020-5915","2571-6662"],"issn-type":[{"value":"0020-5915","type":"print"},{"value":"2571-6662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,8,5]]}}}
