Abstract
Neskatoties uz mūsdienu augstajiem medicīnas sasniegumiem un izmeklēšanas metodēm, Rh izosensibilizētu grūtnieču vadīšanā ir daudz neskaidrības, jo joprojām perinatālā mirstība Rh izosensibilizētu jaundzimušo vidū ir augsta.
ACM MPĀ (arteria cerberi media maksimālplūsmas ātrums) mērījumi tiek uzskatīti par precīzu diagnostikas metodi, lai spriestu par augļa anēmijas esamību. Lai mēs varētu precīzāk spriest par augļa patieso stāvokli, ir papildus diagnostikas metodes, kas ļautu to izvērtēt. Viena no tām ir antieritrocitārās antivielas, ko nosaka pirmajā antenatālās vizītes laikā, grūtniecībai tupinoties, antivielu titrs tiek kontrolēts dinamikā. Pētījuma mērķis: izvērtēt anti–D antivielu titru korelāciju ar ACM MPĀ rādītājiem pirmreizēji un atkārtotas sensibilizācijas gadījumā. Pētījuma hipotēze: anti–D antivielu titrs korelē ar ACM MPĀ mērījumiem tikai pirmreizēji sensibilizētā grūtniecībā. Pētījuma veids: retrospektīvs pētījums, darbam turpinoties – prospektīvs pētījums, kura laikā tika izskatītas pacientes ar diagnozi Rh izosensibilizēta grūtniecība, kurām tika veikti ACM MPĀ mērījumi un ņemts anti–D antivielu titrs vienādos grūtniecības laikos. Pirmreizēji sensibilizētu grūtnieču anti–D antivielu titru ar ACM MPĀ, vidēji stipri, statistiski ticami korelē ar ACM MPĀ. (rs=0.59; p=0.00) Atkārtoti sensibilizētām pacientēm korelācija arī ir vidēji stipra un statistiski ticama. (rs=0,44; p=0.01) Korelācijas ciešums pirmreizēji sensibilizētām grūtniecēm un atkārtoti sensibilizētām grūtniecēm abās grupās neatšķiras. (z=0.89; p=0.04)
Despite modern medical advances and the high level of diagnostic methods, the management of Rh izosensibilization in pregnant women has a lot of unclear things and perinatal mortality of Rh izosensibilizated newborns is high. ACM MPA (arteria cerberi media maximum flow rate) measurements are considered to be an accurate diagnostic method for fetal anemia prediction. So that we can more accurately know the true state of the fetus, in addition to the diagnostic methods that allow to consider it. One of them is anti - erythrocyte antibody, diagnosed at the first antenatal visit, continuing the pregnancy antibody titer is controlled in dynamics. Aim: To evaluate the anti - D antibody titer correlations with ACM MPA at first affected pregnancy and at previously affected pregnancies. Hypothesis : anti-D antibody titers correlates with the MPA ACM only at first affected pregnancy. Methods: a retrospective study, and as the work continues - a prospective study, included patients with a diagnosis of Rh izosensibilizated pregnancy, wich had the ACM MPA measured and anti-D antibody titer analyzed at the same pregancy time. Results: In the first affected pregnancy anti - D antibody titer had moderate correlations with ACM MPA. (rs = 0.59, p = 0.00) In previously affected pregnancy. patients correlation was moderate and statistically significant too. (rs = 0.44, p = 0.01) Conclusion: Overall, it appears that there is no difference between correlations in primary affected pregnancies and previosely affected pregnancies (z = 0.89, p = 0.04) do not difference between groups. (z = 0.89, p = 0.04).
