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.

Long term mortality of mothers and fathers after
pre-eclampsia: population based cohort study

Abstract
Objective To assess whether mothers and fathers
have a higher long term risk of death, particularly
from cardiovascular disease and cancer, after the
mother has had pre-eclampsia.
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-

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

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.

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

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-

Purpose: To examine the association between parity and long-term, all-cause mortality and mortality
owing to specific causes in women.
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.

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.

77. 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.
80. Early e late PE in Italia

81. Conclusioni
• In Italia una sottopopolazione di PE meno frequente…
• … ma più grave perché associata a maggior frequenza di
insufficienza placentare e quindi di FGR
• Il rischio vascolare a distanza negli anni rilevato in alcuni paesi
industrializzati potrebbe non essere rappresentativo della

• L’insulino-resistenza non si associa alla PE placentare e
potrebbe quindi non essere la causa della prognosi

83. Due importanti teorie
The disposable soma
• A causa delle richieste competitive
della riproduzione si investe di meno
nel mantenimento dei tessuti somatici
di quanto non sia necessario per una
lunga sopravvivenza
The antagonistic pleiotropy
• Cer~ alleli che sono favori~ in
conseguenza di un effe€o benefico
precoce (fer~lità e crescita della prole)
presentano anche effe‚ deleteri
tardivi
84. Differenti tipi di PE in alcuni paesi
industrializzati
• Possono spiegare differenze nell’epidemiologia della mortalità
cardiovascolare materna
• La curva di mortalità materna a lungo termine delineata in
Norvegia potrebbe non essere adattabile a quella in Italia
85. Malattia cardiovascolare (CVD)
• Tra 20 aa e 49 aa la frequenza di insulino-resistenza nella
donna raggiunge il 20%
• Molte meno donne sviluppano la PE
• È solo l’insulino-resistenza causa di danno CVD?
• Forse c’è altro….
88. Il “Mild cognitive
impairment” è più
frequente nelle
donne dopo una PE.
Le abilità più
frequentemente
interessate sono
quelle a carico di
funzioni esecutive,
verbali ed attenzione.

• Management of Lipid Disorders
• Insulin Resistance and Diabetes
• Aspirin Therapy
94. 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

/Aterosclerosi
• Similitudini tra PE e aterosclerosi
• Primum movens stato infiammatorio con
attivazione dei monociti/macrofagi
• Endoteliopatia da specie reattive dell’ossigeno
e particelle endotelio-tossiche
• Emissione endoteliale di chemochine,
citochine e molecole di adesione con
invasione leucocitaria del tessuto endoteliale
e ulteriore infiammazione

to the pregnancy itself. 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

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.

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

• I fattori di rischio CV non spiegano completamente
l’esito in malattia CV tardiva
• Il gap tra OR stimati e osservati spiegabile da un rischio
aggiuntivo della PE
• La PE stessa sarebbe un fattore di rischio piuttosto che
un marker di malattia CV
