Follow-up della Preeclampsia ed esiti a distanza - Sergio Ferrazzani

A cura di Sergio Ferrazzani.

La gravidanza è un periodo molto bello della vita di una donna, ma non sempre le cose procedono senza problemi. Alcuni di questi sono particolarmente importanti e possono mettere a rischio la salute della mamma e del bambino. La Preeclampsia, che si manifesta con un aumento della pressione arteriosa e con la perdita di proteine nelle urine, ha un decorso rapidamente ingravescente, talora fulminante, e può danneggiare molti organi materni tra cui cervello, fegato, rene, cuore e sistema circolatorio. Spesso si accompagna a una grave alterazione del sistema della coagulazione, con seri rischi sia emorragici che trombotici. In più compromette quasi inevitabilmente la funzione della placenta e quindi la crescita ed il benessere del feto. Soprattutto nei casi ad esordio in epoche precoci della gravidanza, i danni feto-neonatali comportano disabilità permanenti a causa della prematurità.

È importante pertanto la diagnosi precoce unitamente alla sorveglianza clinica mirata a cogliere precocemente i segni di eventuali complicazioni, al fine di programmare il parto nel momento più opportuno sia per la madre che per il bambino.

Su queste basi questo corso, a più voci di Specialisti scelti in base al loro specifico expertise, si pone l'obiettivo di un aggiornamento del trattamento dell'Ipertensione in gravidanza sulle più recenti linee guida della International Society for the Study of Hypertension in Pregnancy ISSHP per il miglioramento dei sistemi di valutazione e di misurazione dell'efficienza e appropriatezza delle prestazioni nei livelli di assistenza.

Design Population based cohort study of registry data. Subjects Mothers and fathers of all 626 272 births that were the mothers’ first deliveries, recorded in the Norwegian medical birth registry from 1967 to 1992. Parents were divided into two cohorts based on whether the mother had pre-eclampsia during the pregnancy. Subjects were also stratified by whether the birth was term or preterm, given that pre-eclampsia might be more severe in preterm pregnancies. Main outcome measures Total mortality and mortality from cardiovascular causes, cancer, and stroke from 1967 to 1992, from data from the Norwegian registry of causes of death. Results Women who had pre-eclampsia had a 1.2-fold higher long term risk of death (95% confidence interval 1.02 to 1.37) than women who did not have pre-eclampsia. The risk in women with pre-eclampsia and a preterm delivery was 2.71-fold higher (1.99 to 3.68) than in women who did not have pre-eclamptic pregnancies than the fathers of pregnancies in which pre-eclampsia did not occur. Conclusions Genetic factors that increase the risk of cardiovascular disease may also be linked to pre-eclampsia. A possible genetic contribution from fathers to the risk of pre-eclampsia was not reflected in increased risks of death from cardiovascular causes or cancer among fathers. Introduction Pre-eclampsia, which is characterised by hypertension and proteinuria, occurs in 3-5% of pregnancies.1 The condition may be life threatening to the mother and the fetus if it is not properly managed, but it usually ends when the baby and placenta are delivered.2 The causes of pre-eclampsia are not well under- stood. A paradoxical preventive effect when the mother smokes has been established, even though the mechanism is unknown.3 4 Maternal and fetal genes, including paternal genes expressed in the fetus, probably also play a part.1 5 A high risk of recurrence of pre-eclampsia in subsequent pregnancies supports the role of an inherited susceptibility in the maternal genes. In a previous study in Norwegian women we reported a 12-fold increase in the risk of pre-eclampsia in a second pregnancy when the woman had had pre- Medical Birth Registry of Norway, Locus for Registry Based Epidemiology, Department of Public Health and Primary Health Care, University of Bergen, Haukeland Hospital, N5021 Bergen, Norway Henrik U Irgens medical student Lars Reisæter medical student Lorentz M Irgens professor Rolv T Lie professor Correspondence to: L M Irgens lorentz.irgens@ mfr.uib.no BMJ 2001;323:1213–7 significant) decreased risk of cancer.

The effects of these antibodies can be blocked with losartan, a pharmacological AT1 receptor antagonist, or by an antibody-neutralizing peptide (30). However, AT1 receptor autoantibodies do not give explanation for the suppression of aldosterone production noted in preeclampsia (42). Present not only during preg- nancy, AT1 receptor autoantibodies appear to be increased as well in malignant renovascular hyperten- sion and vascular rejection (30). These autoantibodies may account for the increased angiotensin II sensitiv- ity for preeclampsia. In summary, AT1-AA may be one of several insults that can contribute to the placental damage that is proximally linked to the production of anti-angiogenic factors (see FIGURE 4). Immunological intolerance and inflamma- tion/oxidative stress. Immune maladaption remains an intriguing explanation about the pathogenesis of preeclampsia. Normal placentation requires the development of immune tolerance between the fetus and the mother. Preeclampsia occurs more often in first pregnancies, after a change in paternity (94), or with long interpregnancy interval (95). In addition, women using barrier contraceptive methods that reduce maternal exposure to sperm have increased incidence of preeclampsia (46). Women who con- ceived via intracytoplasmic sperm injection (ICSI) in which sperm was surgically obtained from the male had a threefold increased risk of preeclampsia com- pared with ICSI cases where sperm was obtained by ejaculation (102). These observations suggest that preeclampsia may involve an abnormal maternal immune response to novel paternally derived fetal antigens. Women with untreated HIV have a very low incidence of preeclampsia, but the incidence returns to normal in HIV-positive women who are on anti- retroviral therapy (108). Natural killer (NK) cells at the maternal/fetal inter- face are also thought to play an important role in the pathogenesis of preeclampsia. They are thought to be important in modulating immune tolerance required for normal placental development as well as the induction of angiogenic factors and vascular remodel- ing (33). Recent genetic studies have suggested that the susceptibility to preeclampsia may be influenced by polymorphic human leukocyte antigen C (HLA-C) ligands and the killer immunoglobulin receptors 154 PHYSIOLOGY • Volume 24 • June 2009 • www.physiologyonline.org preeclampsia have increased vascular responsiveness to angiotensin II and other vasoconstrictive agents. Angiotensin II is a well recognized octapeptide medi- ator of elevated blood pressure that signals arterial vasoconstriction after binding to the angiotensin II type 1 (AT1) receptor. Angiotensin II hypersensitivity in preeclampsia may also be due to heterodimeriza- tion of AT1 receptors with bradykinin receptors (1). FIGURE 4.

Renin-angiotensin-aldosterone. In addition to altered angiogenic balance and failed cytotrophoblast invasion, the renin-angiotensin-aldosterone axis is also perturbed in preeclampsia. In normal pregnancy, renin, aldosterosterone, and angiotensin are increased. These hormones are suppressed relative to normal pregnancy in preeclampsia. Women with preeclampsia have increased vascular responsiveness to angiotensin II and other vasoconstrictive agents. Angiotensin II is a well recognized octapeptide medi- ator of elevated blood pressure that signals arterial vasoconstriction after binding to the angiotensin II type 1 (AT1) receptor.

Angiotensin II hypersensitivity in preeclampsia may also be due to heterodimeriza- tion of AT1 receptors with bradykinin receptors (1). FIGURE 4. Summary of the pathogenesis of preeclampsia Immune factors (such as AT1-AA), oxidative stress, NK cell abnormalities, and other fac- tors may cause placental dysfunction, which in turn leads to the release of anti-angio- genic factors (such as sFlt1 and sEng) and other inflammatory mediators to induce hypertension, proteinuria, and other complications of preeclampsia.

Methods: This prospective population-based study included 40,454 mothers who gave birth in Western Jerusalem, Israel, to 125,842 children and were followed for an average of 37 years after the birth of their first child. Cox proportional hazards models were used to evaluate long-term total and specific-cause mortality of women by their parity. Results: We found a U-shaped relationship between the number of offspring and risk of all-cause mortality in mothers. After adjustment for sociodemographic characteristics and maternal health and obstetric conditions, higher mortality rates were observed for mothers of 1 child (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.04e1.4), mothers of 5 to 9 children (HR, 1.21; 95% CI, 1.09e1.33), and mothers of 10 or more children (HR, 1.49; 95% CI, 1.12e1.99) compared with mothers of 2 to 4 children. Mortality risk from specific causes including coronary disease, circulatory disease, and cancer were increased for multiparous women. Conclusions: In this long-term follow-up study, there was an association between number of children and mortality risk for mothers. These findings suggest that maternal pregnancies and postnatal character- istics as reflected by number of children may have consequences for long-term maternal health. Ó 2013 Elsevier Inc. All rights reserved. The reproductive patterns of women have long-term implica- tions for women’s health, yet only a few studies have addressed the association between parity, as reflected by number of children, and long-term mortality. Theories from evolutionary biology, such as the “disposable soma” theory, suggest a trade-off between reproductive factors and somatic maintenance [1,2]. These theories are based both on experiments in Drosophila melanogaster and on epidemio- logic studies that show a positive relationship between fertility and mortality [3,4]. The physiologic findings complement the antago- nistic pleiotropy theory, which suggests that deleterious mutations that accumulate during an organism’s lifetime, favor reproduction at younger ages but are harmful at later ages [5,6]. Findings from studies that have investigated historical cohorts as well as contemporary populations have been inconsistent. Although most of these studies showed a positive association between parity and mortality [7e11], others found the opposite association [12e14]. It may be that this inconsistency can to some extent be attributed to short follow-up period, loss to follow-up, misclassification of the number of births (especially in historical cohorts), random error owing to small numbers at the extremes of family size, small differences in mortality risk, and failure to adjust for important potential confounders such as biological and socio- economic factors [15]. The purpose of the current study was to examine the associa- tions between number of children and all-cause mortality and mortality owing to specific causes in mothers after taking into account maternal health conditions as well as lifestyle and socio- economic factors as potential confounders.

  71. 71. Rischio cardiovascolare dopo la PE: Possibili meccanismi Ø Infiammazione/Endoteliopatia/Aterosclerosi. Sia nella preeclampsia a sia nell’aterosclerosi, infatti, il primum movens è uno stato infiammatorio con attivazione dei monociti/macrofagi. Tale processo è agevolato da una endoteliopatia dovuta a specie reattive dell’ossigeno e particelle endotelio-tossiche che favoriscono l’emissione endoteliale di chemochine, citochine e molecole di adesione che portano all’invasione leucocitaria del tessuto endoteliale e dell’infiammazione. Ø Insulino-resistenza/Sindrome metabolica. Studi sull’utilizzo del minimal model e del clamp euglicemico-iperinsulinemico hanno dimostrato una enfatizzazione della fisiologica insulino- resistenza della gravidanza nelle pazienti con ipertensione gestazionale e la preeclampsia tardiva o “maternogenica”. Ø Disfunzione cardiaca. Nelle donne con preeclampsia ricorrente sono stati osservati segni di disfunzione diastolica e diverse anomalie del ventricolo sinistro, che persistono anche fuori gravidanza, mentre nelle donne con preeclampsia episodica non ricorrente mostrano caratteristiche strutturali e funzionali del ventricolo sinistro intermedie, rispetto alla popolazione generale e alle donne con preeclampsia ricorrente.

SINTESI DELLE RACCOMANDAZIONI Livello A: ØLe donne con precedente storia di preeclampsia devono essere informate del loro aumentato rischio di patologia cardiovascolare, devono essere inserite in programmi di screening periodico con valutazione del rischio cardiovascolare e devono essere edotte sulla modificazione dello stile di vita da adottare (cessazione del fumo, riduzione di peso, aumento dell’attività fisica, dieta adeguata). ØAlle donne con persistenza dell’ipertensione arteriosa (Pressione arteriosa 140/90mmHg o 130/80mmHg in pazienti con comorbilità come insufficienza renale cronica o diabete mellito) deve essere iniziata una terapia antipertensiva Livello B: ØValutare la terapia con statine in donne con pregressa preeclampsia e dislipidemia Livello C: ØValutare la profilassi farmacologica con aspirina a basse dosi in base alla stratificazione del rischio

Preeclampsia is considered to be triggered by placental dysfunction, which results in widespread endothelial dysregulation with consecu- tive deficits in perfusion of several organs, including the brain.22 Animal models of placental ischemia have demonstrated impaired cerebral blood flow autoregu- lation and increased blood–brain barrier permeabil- ity.23 Interestingly, the cerebral insult may not be limited to the time of pregnancy; a mouse model of preeclampsia recently showed that after preeclamptic but not normotensive pregnancy carotid injury leads to enhanced vascular remodeling with increased vessel fibrosis.2 This offers a plausible explanation for our finding that the amount of cerebral damage increases with time from pregnancy only in those women who had preeclampsia. This could also be a major factor underlying the increased risk of cerebrovascular disease in women with a history of preeclampsia.1 Another possible link between altered brain architec- 0.81 ,0.01 0.20 20.73 0.60 0.11 ,0.01 0.03a 0.04 0.98 0.61 ,0.01 0.86 0.04 0.98 0.75 ,20.01 0.91 ,0.01 0.72 h-density lipoprotein; HOMA IR 5 homeostatic model assessment Siepmann Neurology® 2017 Modelli animali di ischemia placentare: • ↑ della permeabilità della barriera emato-encefalica e inefficiente autoregolazione del flusso ematico cerebrale • Rimodellamento vascolare carotideo con fibrosi

Email d.berks@erasmusmc.nl Accepted 2 November 2012. Published Online 26 March 2013. Objective This study addresses the following questions. Do cardiovascular risk factors fully explain the odds ratio of cardiovascular risk after pre-eclampsia? What is the effect of lifestyle interventions (exercise, diet, and smoking cessation) after pre-eclampsia on the risk of cardiovascular disease? Design Literature-based study. Setting N/A. Population or Sample N/A. Methods Data for the calculations were taken from studies identified by PubMed searches. First, the differences in cardiovascular risk factors after pre-eclampsia compared with an Results After correction for known cardiovascular risk factors, the odds ratios of pre-eclampsia for ischaemic heart disease and for stroke are 1.89 (IQR 1.76–1.98) and 1.55 (IQR 1.40–1.71), respectively. After pre-eclampsia, lifestyle interventions on exercise, dietary habits, and smoking cessation decrease cardiovascular risk, with an odds ratio of 0.91 (IQR 0.87–0.96). Conclusions Cardiovascular risk factors do not fully explain the risk of cardiovascular disease after pre-eclampsia. The gap between estimated and observed odds ratios may be explained by an additive risk of cardiovascular disease by pre-eclampsia. Furthermore, lifestyle interventions after pre-eclampsia seem to be effective in decreasing cardiovascular risk. Future research is DOI: 10.1111/1471-0528.12191 www.bjog.org Maternal medicine ns.

Future research is needed to overcome the numerous assumptions we had to make in our calculations.
