embark upon a pregnancy. Severe airflow
limitation, with lung function measurements
below 60% of predicted, leads
many units to advise CF women against
becoming pregnant although, as Canny
et al demonstrate, more seriously limited
women can come through pregnancy
successfully.60 it is vital that the developpment
of edema, headaches and
mental confusion is recognized as respiratory
failure and not mistaken for preeclampsia.
After a pregnancy, women with CF have
worse lung function than before, but this
deterioration is no greater than that seen
in non pregnant CF women over a 9month
period.
7. Influenza and the common cold:
Influenza is generally self limited in
healthy young adults. However, if pneumonia
develops, it can be life-threatening
and may be more severe in pregnancy.25.
The influenza vaccine is recommended
for all women who will be
in the second or third trimester of pregnancy
during the influenza season.
Because influenza does not usually result
in a viremia, transplacental infection
rarely occurs. Concern has been raised
about a possible association between influenza
in early pregnancy and anencephaly,
but there is no firm evidence.
Influenza-specific antibody is transmitted
to the fetus in utero and protects
the newborn. However, susceptible newborns
are at increased risk for influenza,
with manifestations ranging from mild
coryza to sepsis. If influenza occurs in
late pregnancy, delivery should be delayed
until the mother has recovered, if
possible, to allow the newborn to acquire
transplacental antibodies. This usually
107
occurs by five days after the onset of
symptoms. The common cold is the most
frequent acute illness affecting humans.
