Short Term Culture

We have studied HLA allogeneic interactions in short-term cultures of lymphocytes from the parents having children with congenital heart defects (CHD), or subject to early reproductive losses. Twentyone married couples (CHD as the main group) who had children with sporadic CHD (interventricular septal defect) without chromosomal diseases were observed. Fifty married couples (a comparison group) had two or more reproductive losses in early gestation (up to 9 weeks), denoted as PNPs (miscarriages, missed abortions, habitual miscarriages. Forty-one families with three or more healthy children represented a control group. Immune response in cell cultures was evaluated by increasing expression of HLA-DR in a mixed culture, as compared to spontaneous lymphocyte cultures. Initial labeling of female and male lymphocytes with monoclonal antibodies to CD45 conjugated to different fluorescent dyes (PC-5 and PC-7) allowed us to evaluate the immune response of female lymphocytes to males and vice versa. The suppressor effect of autologous female serum upon the mixed culture of the lymphocytes of the spouses was also evaluated. Results of the present study showed a difference in HLA allogeneic interactions in the short-term culture of lymphocytes registered for spouses with reproductive losses and children with congenital heart defects. Reproductive losses were associated with a low blocking effect of female auto-serum upon allogeneic HLA interactions in the short-term culture of the lymphocytes of the spouses. Congenital heart defects were associated with high activity of female B-lymphocytes (CD3-/HL-DR+) in short-term mixed culture of lymphocytes from the spouses.

This study is aimed to investigate the effect of female autoserum on the HLA-DR expression in various subpopulations of lymphocytes obtained from spouses with children with sporadic congenital heart defects without chromosomal diseases. 78 married couples with children with congenital heart disease were included in the study group. The control group was formed from 35 married couples with healthy children. The immune response in a mixed culture of lymphocytes of spouses was evaluated by an increased HLA-DR expression in a mixed culture in relation to spontaneous cultures of lymphocytes. Primary staining of female and male lymphocytes by monoclonal antibodies to CD45 conjugated with various fluorescent dyes (PC-5 and PC-7) was performed to assess the immune response of female lymphocytes to male ones and vice versa. The activating effect of female autoserum on all subpopulations of female lymphocytes simultaneously occurred significantly less frequently in the study group compared to the control. The control group was characterized by the domination of the positive effect of female autoserum on HLA-DR expression for all subpopulations of female lymphocyte. For all female lymphocytes having HLA-DR molecule on its membrane, the blocking effect of female autoserum in the study group was significantly more expressed in relation to the control group. Thus, the effect of female autoserum is manifested in relation to the HLA-DR expression on its own lymphocytes, but not on the lymphocytes of the spouse.

A felnőttkorban operált veleszületett szívhibák között vezetnek az I. rekonstrukciós beavatkozások: a) frissen felismert betegségek, b) megelőzően inoperábilisnak ítélt kórképek, c) pulmonalis hypertonia, jobbkamra-elégtelenség miatt „elkésett” műtétek. Növekszik a II. REDO műtétek száma: a) residuumok korrigálása, b) kinőtt, diszfunkciós homograftok cseréje, c) műtéti/intervenciós korrigálás utáni recoarctatio (aneurysma, dissectio) sebészete, d) aorta valvulotomia/valvuloplastica, illetve társvitiumok (TGA) korrigálásának következményeként Ross-műtét, műbillentyű-beültetés . Betegek, eredmények: A 2001–2008 között végzett 4496 műtét közül 166 volt fiatal-felnőtt korú (16–52, átlagéletkor: 28 év) (Ia: 77, Ib: 15, Ic: 4, IIa: 11, IIb: 22, IIc: 9, IId: 28). Műtéti mortalitás nem volt, 1 beteg pulmonalis hypertoniás krízisben, 1 jobbkamra-elégtelenség miatti malignus ritmuszavarban, 2 többszerv-elégtelenségben halt meg. Konklúzió: A rizikófaktorokat a pulmonalis hypertonia és a jobbkamra-elégtelenség jelenti. A bonyolult sebészi megoldások a „congenitalis szívsebész” számára nem jelentenek problémát, de koraibb diagnózisok, terápiában az extracorporalis membránoxigenátor használata az eredményeket javíthatja.
