Long-term monitoring of immunological profile in children with immunodeficiency disorders.
1. The fulfillment of research project allowed us to make deeper scope of literature sources with the children IDS topic. The proper experience with children IDS management has been acquired in the specialized service for immunodeficient children at Pediatric Clinic of Teaching Hospital in Hradec Králové. 2. IDS screening and diagnostic in children were studied with participation of immunologic laboratories, and the development of available immunologic indices in IDS children has been monitored at long-term. Problems mentioned were the content of partial research project VII-6-6/19 for 1976-1980, VII-6-6/9 for 1980-1985, VIII-6-5/11 starting from 1986 and resolved till now by Pediatric Clinic of Teaching Hospital in Hradec Králové. The immunodeficient conditions were studied minutely at long-term and with complex relations. 3. Authors were involved in management of life threatening infectious complications and performed both control and moderation of diseases manifested as such. Applied management approaches were then evaluated from the scope of actual therapy. Our pathophysiologic IDS concept is more extended. The individual IDS represents a complex real situation developing in time. Therefore, the long-term monitoring is of benefit in detecting certain developmental IDS tendencies such as, e. g., occurrence of autoimmune diseases and malignancies in children with IDS. 4. We stated that thymectomy in infants: --was of no expressed disturbing influence on health of two children at least for 12 years of long-term monitoring; --manifested the transient decrease of circulating T-lymphocyte percentage which was detected in one child 2 years after TE, in other up 10 years after TE, respectively. However, both of them showed a constant decreasing tendency; --is responsible of changes in subpopulations of T-lymphocytes; --changes of laboratory tests provided after TE 12 years till now show no clinical significance. 5. Selective IgA deficiency has been diagnosed in a total of 14 children, and the development of their immunologic indices was monitored at long-term. Several literature data were proved as well as enlarged and extended: --IgA deficiency is a constant defect; --this is a simultaneous deficiency of both serum and secretory IgA in a majority of cases; --selective IgA deficiency is most pronounced and complex immunity disorder involving not only humoral, but also cellular immunity; --in IgA deficiencies, mainly respiratory infections are predominant though having neither serious course nor complications; --immunoglobulins are not necessary in managing infections in IgA deficient cases for as much as an appropriate antiinfection therapy is of choice. Dispensary care is needed similarly to other IDS conditions due to recurrent infections and risk of autoimmune diseases and tumors.(ABSTRACT TRUNCATED AT 400 WORDS)
