• ACE inhibitors can be divided into three groups based on their molecular structure:• Sulfhydryl-containing agents[edit]• Captopril (trade name Capoten), the first ACE inhibitor• Zofenopril• Dicarboxylate-containing agents[edit]• This is the largest group, including:• Enalapril (Vasotec/Renitec)• Ramipril (Altace/Prilace/Ramace/Ramiwin/Triatec/Tritace)• Quinapril (Accupril)• Perindopril (Coversyl/Aceon/Perindo)• Lisinopril (Listril/Lopril/Novatec/Prinivil/Zestril)• Benazepril (Lotensin)• Imidapril (Tanatril)• Trandolapril (Mavik/Odrik/Gopten)• Cilazapril (Inhibace)• Phosphonate-containing agents[edit]• Fosinopril (Fositen/Monopril) is the only member of this group• Naturally occurring[edit]• Casokinins and lactokinins, breakdown products of casein and whey, occur naturally after ingestion of milk products, especially
cultured milk. Their role in blood pressure control is uncertain.[24]
• The lactotripeptides Val-Pro-Pro and Ile-Pro-Pro produced by the probiotic Lactobacillus helveticus or derived from casein have been shown to have ACE-inhibiting and antihypertensive functions

Preconception Counseling for Pregestational Diabetes
• Advise reproductive age women with diabetes about
reliable birth control– NOTE: Metformin in PCOS may improve fertility need to
warn about possible pregnancy
– Metformin safe for ovulation induction in PCOS
• Achieving a healthy weight is essential – obesity
associated with adverse pregnancy outcomes
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
• Metformin is safe in pregnancy and women with gestational diabetes treated with metformin have less weight gain during pregnancy than those treated with insulin. Babies born to women treated with metformin have been found to develop less visceral fat, making them less prone to insulin resistance in later life.
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Screen for Complications: Pre-pregnancy and Intrapartum
Screening for:
1. Retinopathy: Need ophthalmological evaluation
2. Nephropathy: Assess creatinine + urine
microalbumin / creatinine ratio (ACR)– Women with microalbuminuria or overt nephropathy are at
↑ risk for hypertension and preeclampsia
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Recommendations 1-2: Preconception Care
1. All women of reproductive age with type 1 or type 2
diabetes should receive advice on reliable birth control,
the importance of glycemic control prior to pregnancy,
impact of BMI on pregnancy outcomes, need for folic
acid and the need to stop potentially embyropathic
drugs prior to pregnancy [Grade D, Level 4].
2. Women with type 2 diabetes and irregular
menses/PCOS who are started on metformin or a
should be advised that fertility may improve and be
warned about possible pregnancy [Grade D, Consensus].

guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Recommendation 3: Preconception Care
3. Before attempting to become pregnant, women
with type 1 or type 2 diabetes should:
a) Receive preconception counseling that
includes optimal diabetes management and
nutrition, preferably in consultation with an
interdisciplinary pregnancy team to optimize
maternal and neonatal outcomes [Grade C, Level 3]
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Recommendation 3: Preconception Care (continued)
b) Strive to attain a preconception A1C of ≤7.0% (or
A1C as close to normal as can safely be achieved)
to decrease the risk of:
– Spontaneous abortion [Grade C, Level 3]
– Congenital anomalies [Grade C, Level 3]
– Pre-eclampsia [Grade C, Level 3]
– Progression of retinopathy in pregnancy [Grade A, level
1 for type 1 diabetes (23); Grade D, Consensus for type 2 diabetes]
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
c) Supplement their diet with multivitamins containing 5
mg of folic acid at least 3 months pre-conception
and continuing until at least 12 weeks post-
conception [Grade D, Level 4]. Supplementation should
continue with a multivitamin containing 0.4-1.0 mg
of folic acid from 12 weeks postconception
through to 6 weeks postpartum or as long as
breastfeeding continues [Grade D, Consensus].
Recommendation 3: Preconception Care (continued)
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
d) Discontinue medications that are potentially
embryopathic, including any from the following
classes:
• ACE inhibitors and ARBs prior to conception
or upon detection of pregnancy [Grade C, Level 3]
• Statins [Grade D, Level 4]
2013
Recommendation 3: Preconception Care (continued)
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
4. Women with type 2 diabetes who are planning a
pregnancy should switch from non-insulin
antihyperglycemic agents to insulin for glycemic
control [Grade D, Consensus].
Women with pregestational diabetes who also
have PCOS may continue metformin for
ovulation induction [Grade D, Consensus].
Recommendation 4: Preconception Care
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Recommendations 5 and 6: Preconception and Complications
5. Women should undergo an ophthalmological
evaluation by an eye care specialist [Grade A, Level 1, for
type 1; Grade D, Level 4 for type 2].
6. Women should be screened for chronic kidney
disease prior to pregnancy [Grade D level 4 for type 1 diabetes
Grade D, consensus for type 2 diabetes]. Women with
microalbuminuria or overt nephropathy are at
increased risk for the development of HTN and
preeclampsia [Grade A level 1]; and should be followed
closely for these conditions [Grade D, Consensus]

because of the increased risk of severe
hypoglycemia during pregnancy [Grade D, Consensus]
d) Perform SMBG, both pre- and postprandially
to achieve glycemic targets and improve
pregnancy outcomes [Grade C, Level 3]

Remains a Controversial Topic …
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Considerations for the CDA Adopting the IADPSG Thresholds
• How can we select an odds ratio threshold in the
absence of a true threshold in the data?
• What is the impact on the patient and workload of
increasing the prevalence of GDM?
• Do we have sufficient evidence with respect to
treatment benefit at the various thresholds to make
an informed decision?
• In the absence of clear benefit, should the diagnostic
criteria be changed from 2008?

2013 CDA Diagnostic Criteria for GDM
PREFERRED APPROACH (2 steps)
1. 50 gram glucose challenge test
2. 75 gram oral glucose tolerance test
– Using thresholds of OR 2.0
ALTERNATIVE APPROACH (1 step)

Recommendations 16-17: Diagnosis of GDM
16.All pregnant women should be screened for GDM
at 24-28 weeks of gestation [Grade C, Level 3].
17. If there is a high risk of GDM based on multiple
clinical factors, screening should be offered at any
stage in the pregnancy [Grade D, Consensus]. If the initial
screening is performed before 24 weeks of
gestation and is negative, rescreen between 24-28
weeks of gestation. (see next slide)
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Recommendation 17: Risk Factors for GDM (continued)
• Age ≥35 years
• Previous GDM
• Prediabetes
• High risk population – Aboriginal, Hispanic, South
Asian, Asian, African
• BMI ≥30 kg/m2
• Polycystic ovarian
syndrome
• Acanthosis nigricans
• Corticosteroid use
• History of macrosomic
infant
• Current fetal macrosomia
or polyhydramnios [Grade D, Consensus]
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Recommendation 18: Diagnosis of GDM
18.The preferred approach for the screening and
diagnosis of GDM is the following [Grade D, Consensus]:
a) Screening for GDM should be conducted using the 50 g
glucose challenge test (GCT) administered in the non-
fasting state with plasma glucose measured one hour later
[Grade D, Level 4]. A plasma glucose value ≥7.8 mmol/L at
one hour will be considered a positive screen and will be
an indication to proceed to the 75 gram OGTT [Grade C, Level
2]. A plasma glucose value >11.1 mmol/L can be
considered to be diagnostic of gestational diabetes and
does not require a 75 gram OGTT for confirmation [Grade C,
Level 3].

guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Recommendation 18: Diagnosis of GDM (continued)
b) If the GCT screen is positive, a 75 gram OGTT
should be performed as the diagnostic test for
GDM using the following criteria: >1 of the
following values: – Fasting >5.3 mmol/L,
– 1h >10.6 mmol/L,
– 2h >9.0 mmol/L [Grade B, Level 1]

Recommendation 19: Diagnosis of GDM
19.An alternative approach that may be used to screen
and diagnose GDM is the one-step approach [Grade D,
Consensus]:
a) A 75 gram OGTT should be performed (with no
prior screening 50g GCT) as the diagnostic test for
GDM using the following criteria [Grade D, Consensus]:
≥1 of the following values: – Fasting > 5.1 mmol/L, – 1h > 10.0 mmol/L, – 2h > 8.5 mmol/L [Grade B, Level 1 (4)]

What About Insulin Analogues and Oral Agents Among Patients with GDM?
• May use rapid-acting analog insulin for postprandial
glucose control – no difference in perinatal outcomes
• May use glyburide or metformin for women who
are non-adherent to or who refuse insulin– Likely safe BUT it is OFF-Label no long-term data, need
discussion with patient

GDM: Glycemic Management During Labour and Delivery
• Keep maternal blood glucose l between 4.0 and 7.0
mmol/L reduce risk of neonatal hypoglycemia
• Women should receive adequate glucose during
labour in order to meet the high energy requirements

Postpartum GDM Management Checklist
1. Encourage Breastfeeding
2. 75g OGTT between 6 weeks - 6 months
postpartum to detect prediabetes or diabetes
3. Discuss increased long-term risk of diabetes –

Recommendation 20: Management During Pregnancy (GDM)
20.Women with GDM should:
a. Strive for target glucose values: – Fasting PG below 5.3 mmol/L [Grade B, Level 2]
– 1h postprandial below 7.8 mmol/L [Grade B, Level 2]
– 2h postprandial below 6.7 mmol/L [Grade B, Level 2]
b. Perform SMBG, both fasting and postprandially to
achieve glycemic targets and improve pregnancy
outcomes [Grade B, Level 2]
c. Avoid ketosis during pregnancy [Grade C, Level 3]
guidelines.diabetes.ca | 1-800-BANTING (226-8464) | diabetes.caCopyright © 2013 Canadian Diabetes Association
Recommendation 21: Management During Pregnancy (GDM)
21.Receive nutrition counseling from a registered
dietitian during pregnancy [Grade C, Level 3] and
postpartum [Grade D, Consensus]. Recommendations for
weight gain during pregnancy should be based on
pregravid BMI [Grade D, Consensus].

Recommendation 22 and 24: Management During Pregnancy (GDM)
22. If women with GDM do not achieve glycemic targets
within 2 weeks from nutritional therapy alone,
insulin therapy should be initiated [Grade D, Consensus].
23. Insulin therapy in the form of multiple injections
should be used [Grade A, Level 1].
24.Rapid-acting bolus analog insulin may be used
over regular insulin for postprandial glucose control
although perinatal outcomes are similar [Grade B, Level 2].

Recommendation 25: Management During Pregnancy (GDM)
25.For women who are non-adherent to or who refuse
insulin, glyburide [Grade B, Level 2] or metformin [Grade B,
Level 2] may be used as alternative agents for
glycemic control. Use of oral agents in pregnancy is
off-label and this should be discussed with the
patient [Grade D, Consensus].

Recommendation 26: Intrapartum Management (GDM)
26.Women should be closely monitored during labour
and delivery and maternal blood glucose levels
should be kept between 4.0 and 7.0 mmol/L in
order to minimize the risk of neonatal hypoglycemia. [Grade D, Consensus]
27.Women should receive adequate glucose during
labour in order to meet the high energy requirements [Grade D, Consensus].

Recommendation 28: Postpartum (GDM)
28.Women with GDM should be encouraged to
breastfeed immediately after delivery in order to
avoid neonatal hypoglycemia [Grade D, Level 4] and to
continue for at least three months postpartum in
order to prevent childhood obesity [Grade C, Level 3] and
reduce risk of maternal hyperglycemia [Grade C, Level 3].
29.Women should be screened with a 75g OGTT
between 6 weeks and 6 months postpartum to
detect prediabetes and diabetes [Grade D, Consensus].
