The aim of this study was to evaluate the side effects of Jadelle® implants in the immediate postpartum and study their impact on the metabolism and growth of the newborn and infant.
Materials and Method: To do this, we inserted the implants at two different postpartum period : first, between the first and the seventh day for the immediate postpartum period (IPP) group ; second, between the 45th and the 3rd postpartum months for the late postpartum (LPP) group. The variables studied were birth route, weight at birth, quality of milky climb, pregnancy term at time of delivery, complaints, the weight, height, head, brachial, thoracic and cranial perimeters and their evolution over time.
Results : In both groups, full-term infants were the most numerous. In the IPP group, however, the proportion of premature babies was slightly higher than in the other group. In both groups, the upper lane (caesarean section) was the most frequently reported delivery route, 86% for the late postpartum group and 70% for the immediate postpartum group. In the IPP group, insertions took place on the third postpartum day for the majority of patients, and were all done before the seventh day. The LPP group took place at six weeks and rarely more than two months (four cases only). The mean weights of the two groups were not very different. They were 2920g and 2930g respectively for the immediate postpartum group and the late postpartum group. This was not the case for the maxima of 4400g and 5000g respectively for the IPP and LPP group. By correcting this discrepancy, there is no statistically significant difference in infant growth. The same is true for newborns of low birth weight. Given the low sample size after adjusting the data, caution is required in interpreting these results. we found that the metabolism of the liver was not disturbed by the product.
Conclusion: Our results are encouraging to further promote contraception in the immediate postpartum period in developing countries and thus reach a wide range of users. We can therefore say that the side effects are not different during this period and largely are also tolerated.
In sub-Saharan Africa, maternal mortality remains at a worrying level. Every year more than 500,000 women lose their lives by giving birth. In Senegal, it is currently 392 per 100,000 live births . Birth spacing has been strongly advised by world health organization (WHO) to reduce these alarming rates . Immediate postpartum can be widely depicted by high-profile hospitals such as ours to reduce missed opportunities. Indeed, most of the patients are referred to other structures. Reducing unmet need for contraception especially after childbirth is a major challenge in sub-Saharan Africa. This period is undoubtedly more delicate for a prescription of hormonal contraceptives. Because of this, the enzymatic immaturity of the fetal liver where a metabolism of the products used. This period can be considered
a difficult contraception because of neonatal hepatic immaturity. The objective of this study is to assess the safety of levonorgestrel in the newborn and infant during the first six months of life.
We included in this study all patients who had a natural birth or caesarean delivery in our service during the collection period, who accepted the contraceptive method by Jadelle® implants after counseling and who were not contraindicated for this method. We don’t included all patients with contraindications for the use of hormonal contraception or breast-feeding and newborns with a severe condition and finally patients who did not consent to the use of the method. The insertion was made after delivery before returning home or during post-natal consultations. It occurred between the first and the seventh day of the postpartum period
for the immediate postpartum period (IPP) group and between
the 45th and the 3rd postpartum months for the late postpartum
(LPP) group at the internal side of the arm (of the non-dominant
member). The procedue was practiced by the same practitioner.
From the date of insertion, patients were monitored on a monthly
basis. During the post-insertion consultations, patients were
completely clinical examinated. All the patients were examined
by the same practitioner. The variables studied were age, childbirth,
caesarean section, quality of milky rise, age last child,
contraception, pregnancy term at time of delivery, complaints,
weight. At each consultation, clinical (weight, height, perimeter,
brachial and thoracic) and biological (transaminases, bilirubin)
constants were recorded monthly and quarterly respectively.
The data collected was processed using the EXCEL software for
Windows Office 2010 for the global computerization of data and
the production of tables and figures and SPSS 17.0 for Windows
for the calculation of means and tests of significance.
Due to the absence of ultrasound dating of the pregnancy and
the date of the last precise menstruations, the precise terms of
the pregnancies at the time of delivery could not be specified.
The subjective criterion used was the clinical examination of the
newborn at birth, the birth weight and the presumed term given
by the mother. In both groups, full-term infants were the most
numerous. In the IPP group, however, the proportion of premature
babies was slightly higher than in the other group (Table 1).
In both groups, the caesarean section was the most frequently
reported delivery route, 86% for the late postpartum group
and 70% for the immediate postpartum group. There was no significant
difference between the two groups (p=0.53).
In the IPP group, insertions took place on the third postpartum
day for the majority of patients, and were all done before the
seventh day. The LPP group took place at six weeks and rarely
more than two months (four cases only).
The mean weights of the two groups were not different. They
were 2920g and 2930g respectively for the immediate postpartum
group and the late postpartum group. This was not the case
for the maxima of 4400g and 5000g respectively for the IPP and
LPP group (Figure 1&2).
All our patients had initially opted for exclusive breastfeeding
for the first six months. When the Jadelle® implants were
inserted, the milky rise was considered satisfactory, as was the
post-natal consultation for all patients.
Taken as a whole, neonates did not differ in the change in infant
weight as a function of time if the weight difference was taken
into account for children in the late postpartum group present
at recruitment. Mean monthly weight gain ranged from 706g to
1214g for IPP group babies, and from 669g to 1096g for the LPP
group; with a respective average weight gain of 912g and 763g
(Table 2). By correcting this discrepancy, there is no statistically
significant difference in infant growth. The same is true for newborns
of low birth weight. Given the low sample size after adjusting
the data, caution is required in interpreting these results. The
weight at the first consultation is taken as a reference. For newborns
with low birth weight, weight gain was steady and faster than that of eutrophic newborns at birth. In the IPP group, the
mean weight at first visit was 2083.33g and 8840.00g at the last,
resulting in an average monthly gain of 1126.16g. For the LPP
group, the mean weight at the first visit was 2400g and 7300g at
the last, giving an average monthly weight gain of 806.66g (Table
In the immediate postpartum group, the mean monthly gain
of 1.98 cm for all newborns combined. For the late postpartum
group, it was 2.60cm. The two evolutionary curves show a steady
rise in the size of the first to the sixth post-natal visit. The evolutionary
curves of low birth weight babies in the two groups
are broadly similar, as they are all ascending from the first to the
sixth postnatal consultation (Table 4&5).
Infants in the immediate postpartum group had an average
cranial perimeter of 37.84cm at the first consultation and
44.52cm at the last. Those of the other group had an average of
39.14cm at the first consultation and 45.32cm at the last. For
newborns of low birth weight have also experienced a growing
ascent (Table 6&7).
The mean thoracic perimeter of infants in the immediate
postpartum group at the first visit was 36.71cm and 44.37cm at
the last. For those of the late postpartum it was 39.3cm at the
first visit and 45.71cm at the sixth. But on the curves of comparative
evolution, this difference does not appear, the curves being
almost confounded. For newborns of low birth weight taken
separately, those of the immediate postpartum had an average
of 32.67cm at the first consultation and 44cm at the last. As for
those in the other group, the average at the first consultation was
32cm and 42cm at the last. There is also no significant difference
in the chest perimeter curves of premature infants. There is a
steady and continuous increase from the first to the sixth postnatal
consultation. The data from the first consultation were taken
The mean transaminase level of all late postpartum infants
was 44 IU at the first consultation, 35 IU at the third and 16 IU at
the last consultation. There are, however, maxima of 117, 90 and
77. In the immediate postpartum group, these mean rates were
respectively 41.89, 42.26 and 38.82 IU/L. However, maximum
rates of 134, 80 and 100 IU were observed in the first, second
and third consultations. On the evolution curves, there is a gradual
decrease in average rates over time.
The mean rate of transaminases in newborns in the late
postpartum group at the first prenatal visit was 20.6591 IU/L,
16.74 IU/L at the third consultation and 20.88 IU/L at the sixth
consultation. Taking 40UI/ L as the upper limit of reference, 6%
of infants, including those born prematurely or with a low birth weight, had a high ALT transaminase level but never doubled
this level. These rates were 44, 52 and 68 IU/L. In the immediate
postpartum group, the mean rates at the 1st, 2nd and 6th
post-natal consultations were 26.90 IU/L, 26.63 IU/L and 23.64
IU/L. but six of the infants had high levels above 40 IU/L but did
not double this rate. In the immediate postpartum group, mean
ALT rates tended to decline gradually, which was almost the reverse
of what was observed in the other group. In both groups,
there were no abnormally high rates in low birth weight babies.
In the infants of the immediate postpartum group, the mean
total bilirubin levels during the consultations were 2.0737,
0.6029 and 0.3488 μmol/L at the first, third and sixth consultations,
respectively. In the late postpartum group, these same
rates were 1.7243, 0.6797, 0.395 μmol/L at the three postnatal
consultations. Since the normal total bilirubin level did not
exceed 6 μmol/L, none of the infants followed had pathological
For indirect bilirubin, mean rates in the immediate postpartum
group were 0.9955, 0.4138 and 0.325 μmol/L for the three
postnatal visits. In the late postpartum group, these rates were
respectively 0.7151, 0.6259 and 0.3536 μmol/L, respectively; but
with a maximum rate of 10.68 μmol/L at the first consultation.
Evolution curves in both groups showed rates with a progressive
decrease in postnatal follow-up, none of which had reached
In the immediate postpartum group, the mean rates at the
three post-natal consultations were 1.029, 0.3644 and 0.2705
μmol/L. But high levels were noted with a maximum of 13.6
μmoles/L at the first. In the late postpartum group, the respective
rates were 0.871, 0.2784 and 0.2257 μmol/L. Here a maximum
level of 10 μmol/L is also obtained at the following consultation.
The curves of rates in both groups had a tendency to
decrease as time went on.
The need for immediate postpartum use of hormonal contraception
during breastfeeding is a complex problem. Progestin-
only implants (Norplant®, Jadelle® and Implanon®) deliver
a product that remains active after secretion into breast milk. But
the proof of the deleterious effects of these steroids absorbed
by the newborn exposed in the early days of the postpartum remains
to be established.
For patients in the IPP group, the minimum weight found at
the first visit was 1300g and the maximum weight was 4300g
with an average weight of 2920g. In the LPP group the extremes
were 1600g for the minimum and 5000g for the maximum weight
with an average of 2930g. The figures below provide information
on the evolution of average weight and height of infants in
both sexes compared to WHO standards (z-scores) (Figure 3&4).
Many studies have been conducted to evaluate the effect of hormones
(including progesterone) in contraceptives on the quality
of milder growth and neonatal growth [3-6]. All performed with
an introduction after six weeks postpartum, they did not report
deleterious effects on infant growth (Figure 5&6).
A study comparing the growth of infants of mothers on Norplant
® inserted after six weeks postpartum on the one hand and
copper IUD on the other hand showed no difference between the two groups . The same is true for the levonorgestrel intrauterine
device (Mirena®) [7-9]. We can deduce that there is no
difference between the two groups on the one hand and on the
other hand with the WHO standards, and these data are consistent
with those of the literature.
On the evolution curves there is a gradual decrease in average
rates over time. Infants, having rates greater than or equal
to twice the normal rate at the first visit, had no visible clinical
manifestations and during control these rates normalized. There
are no data available in the literature that took into account biological
parameters. In both groups there are no abnormally high
rates in low birth weight. There were no clinical manifestations
in infants with high levels. No data from the literature is available
to compare the results.
The normal total bilirubin level should not exceed 6 μmol/L,
none of the infants followed, in this case had pathological levels.
Rates evolution curves in both groups tended to decrease rates,
initially high over time. This phenomenon could share the same
mechanism of occurrence as neonatal jaundice. The evolution
curves in both groups show rates with a progressive decreasing
trend along the postnatal follow-up, and none of these rates had
reached a pathological value. No data from the literature is available
to compare the results.
In light of these findings, we can say that the early introduction
of progestational contraception in the postpartum before
returning home does not seem to alter the hepatic metabolism
in normal neonates breastfed exclusively in the breast. And it
would be prudent to avoid its use in case of pathological situation
(liver disease, severe neonatal jaundice, fetal distress). To
minimize the risk of disruption of hepatic metabolism, the examination
of the newborn should be systematic.
