Preeclampsia and eclampsia cause significant morbidity and mortality for mothers and neonates in Peru. Recent studies have suggested that secretion excess of a naturally occurring anti-angiogenic molecule of placental origin (soluble fmslike tyrosine kinase-1 - sFlt-1, or sVEGFR-1) may contribute to the pathogenesis of preeclampsia. sFlt-1 acts by antagonizing two pro-angiogenic molecules –vascular endothelial growth factor (VEGF) and placental growth factor (PLGF). Abnormalities in the angiogenic balance have been proposed as having a major role in the molecular cascade leading to proteinuria, hypertension, and endothelial dysfunction. Further evidence supports the hypothesis that angiogenic balance is crucial for differentiation and invasion of cytotrophoblasts. The abnormal placentation and the accompanying hypoxia may, in turn, result in more sFlt-1 production, thus leading to a vi...

We show how diabetes mellitus complicates pregnancy and what are the risks these patients and their newborns are exposed to. For this purpose the experience of Hospital San Bartolomé was revised. From January 1972 to December 1989, 56,347 pregnant women attended for pre-natal care, 11,298 (20%) women had diabetes risk factors and underwent oral glucose tolerance (OGIT) according to conventional criteria 538 patients were identified as pregnancy complicated by diabetes (GDM). Mean age was 31 y.o. (DS ± 6,5). 525 GDM (97,6%) were gestational diabetes (GD) and 13 (2,4%) pregestational diabetes (PGD). These latter were older than GD (p<0,05). 54 patients were lost (10%) and did riot deliver at the hospital. GDM women had significant maternal and perinatal complications in comparison to the total pregnant population (p<0,005). Considering abnormal plasma fasting glucose ³ 80 mg/dl (4,5 mM/...

Diabetes mellitus is a state of impaired glucose tolerance, caused by inadequate or ineffective insulin secretion action thereof. This altered metabolic state may worsen during pregnancy because pregnancy causes changes in metabolism of carbohydrates, fats and proteins that can aggravate diabetes in patients with a genetic predisposition for the disease.

Fetal macrosomia has been traditionally defined based on an arbitrary birthweight. However, fetal macrosomia is currently defined as a large for gestational age infant (>90 percentil) because of increased perinatal risk. This prospective investigation performed at San Bartolome's Hospital in Lima, Peru, included 1697 pregnant women from June 1990 to June 1993. 278 pregnant women had large infants (LGA) and 1 336 had normal sized infants. The predictor factors for LGA were: excessive weight gain (70%), male fetal sex (77%), placental width > 4 cm (74%), age over 30 years old (41,7%), obesity (33,5%), previous large infant (27%), fasting blood sugar > 79 mg/cIl (21,6%), 2h  post  prandial glucose > 110 mg/dl (20,7%), height > 160 cm (20%), familial diabetes (13,7%) and anemia (10, 1 %). The predictable maternal complications were: excessive weight gain, anemia, threatened abortion, place...

651 pregnant women at 26 to 36 weeks gestation were tested 1 hour with 50 g oral load of glucose (Test 50 g). They are passing the threshold of greater than or equal 130 mg / dl in plasma were suspicious of Gestational Diabetes (SDG). You're were subsequently tested oral glucose tolerance (OGTT) stop the diagnosis of gestational diabetes mellitus (BG) according to the criteria of the National Diabetes Data Group. The age of pregnant women was 26.3 ± 6.4 years (mean ± SD), range 16-45 years. 310 pregnant women (47.6%) did not have any risk factors for diabetes mellitus. 57 pregnant women (8.7%) were SDG. 32 (4.9%) underwent OGTT, resulting DG 24 patients (3.7%). There was no significant difference in the incidence of BG in people with risk factors and those that had not. The sensitivity of the test was 50 g of 88.9% and specificity of 95.2%. There were 3 DG not detected by the test; so ...

The HAPO study encompassed 25,505 unique pregnancies across 9 countries, which underwent a 2-hour Oral Glucose Tolerance Test (OGTT) with 75 g of glucose between weeks 24 to 32 of gestation. In 2010, the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) reported that the diagnosis of hyperglycemia in pregnancy could be established using fasting values, and 1 and 2 hours post OGTT levels associated with a 1.75 times increased risk above the average of adverse effects found in the HAPO study. These levels corresponded to fasting blood sugar ≥ 92 mg/dl, 1-hour blood sugar ≥ 180 mg/dl, and 2-hour blood sugar ≥ 153 mg/dl. Although the OGTT in the HAPO study was conducted from week 24 to 32 of pregnancy, the World Health Organization in 2013 recommended using these values for the diagnosis of hyperglycemia in pregnancy outside of this gestational period, a rec...

A propósito de la reciente promulgación de la Resolución Ministerial N.º 486-2014/Minsa, que aprueba la guía técnica nacional para el aborto terapéutico, se ha generado un gran debate al respecto. Como un aporte a la discusión, se presenta una revisión sobre las definiciones y tipos de aborto, para luego centrarse en el denominado ‘aborto terapéutico’ y explorar las  dificultades que existen para definirlo. Finalmente, sepresentan algunas observaciones a esta Guía técnica emitida por el Minsa. Se concluye que el término ‘aborto terapéutico’ es anacrónico y contradictorio porque el aborto no es un tratamiento que asegure mejorar la salud de la mujer ni la del niño. El término apropiado debería ser ‘interrupción del embarazo por razones médicas’.

Blood samples in the rasting state were drawn rrom 1,560 non diabetic Peruvan pregnant women at 26 to 36 weeks or gestatlon in order to establish a normal range für fasting serum glucose in pregnancy (ortho-tolouidine method) and to examine whether maternal-fetal prognosis differs when maternal fasting blood sugar (FBS) values are beyond this range. The 3rd, 50th and 95th percentiles were SO, 67, 80 and 85 mg/dl, respectively. Pregnant women with diabetes risk factors had mean serum glucose values higher titan pregnant women without such risk factors significantly. Follow up was completed on 1,415 (90.7%) of the pregnancies and 1,043 (67%) of the newborns. Maternal FDS showed a positive association to diabetes rlsk factors, pregnancy complicatlons, feto-pelvic disproportion, shoulder dystocia, operative deliveries and perinatal morbidity and mortality. A significant increase In the mate...

Introduction. Cesarean section is one of the most predominant surgical procedures worldwide. In Peru, national datashows that our rates fluctuate around 36%, and a prevalent factor in the indication for cesarean delivery is previous cesarean section. Objective. To determine the prevalence of previous cesarean section as an indication for cesarean deliveryin a Peruvian hospital during the period from January to December 2022. Materials and Methods. A descriptive studywas carried out based on the information from the medical records of pregnant women with an indication for cesarean delivery attended in a hospital. From a population of 6100 pregnant women attended in 2022, a total of 236 medical recordsof patients who underwent cesarean section with a history of cesarean section were obtained. Sociodemographic andclinical information was extracted. Results. It was found that the prevalence ...
