December 24, 2021 updated by: ENRIQUE REYES-Munoz MD, Instituto Nacional de Perinatologia Isidro Espinosa de los Reyes

Efficacy of Two Schemes of Self-monitoring Capillary Glucose to Monitor Glycemic Control in Mexican Women With GDM

Gestational diabetes mellitus (GDM) affects 10 % of women who receive prenatal care at Instituto Nacional de Perinatología (Mexico, City). Currently, there is clear evidence on the utility of self- monitoring of capillary glucose (SMGC) to evaluate the efficacy of medical-nutrition therapy on glycemic control. However, the reports regarding the best pattern of SMGC in terms of frequency and number of determinations per day are limited. The objective of this study is to evaluate the efficacy of two SMGC schemes for monitoring glycemic control in Mexican women with GDM.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Currently, the evidence from randomized clinical trials about the most appropriate scheme of SMGC for monitoring the glycemic control among women with GDM is limited. This study was designed to evaluate the efficacy of two different schemes of SMGC in GDM Mexican population, it is an open-label randomized clinical trial including 2 groups: group 1 (SMGC 4 times/day) measured in fasting and 1 hour postprandial of breakfast, lunch and dinner; group 2 (SMGC 2 times/day), measured preprandial and 1 hour postprandial, of breakfast, lunch or dinner, alternating the meal each day, from GDM diagnosis until the resolution of pregnancy. Additionally, determinations of insulin, lipids and glycosylated hemoglobin (HbA1c) will be determinate at enrollment, and between the 30-32 and 36-38 of gestation week. The primary outcome: To compare the proportion of women who achieve glycemic control using SMGC 4 times/day versus SMGC 2 times/day.

Secondary outcome: To compare the risk of new-born large for gestational age, gestational hypertension, preeclampsia, preterm birth, cesarean section, new-born weight, neonatal hypoglycemia, neonatal hyperbilirubinemia and entry to neonatal intensive care between groups. An analysis for intention of treatment will be made according to the recommendations of the CONSORT guidelines.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

  • GDM diagnosis, defined by 2 or more altered values during oral glucose tolerance test (75g-2h): Fasting ≥ 95 mg/dl, 1 hour ≥ 180 mg/dl and 2 hours ≥ 155 mg/dl.
  • Singleton pregnancy between 12-32 weeks of gestation at GDM diagnosis.

Exclusion Criteria:

  1. Multiple pregnancy.
