[Calcium-phosphorus-magnesium homeostasis in women with threatened abortion].

One hundred twenty eight women were submitted to research including: 38 healthy not pregnant women, 40 healthy women in the first trimester of uncomplicated pregnancy (6-15 weeks) and 50 pregnant women with symptoms of threatened abortion (6-15 weeks). The following parameters were measured in serum: total Ca, Ca++, ionised inorganic phosphorus (Pi), magnesium (Mg), total protein and albumin and also total alkaline phosphatase activity (APt). Micromethods generally accepted in clinical laboratories were used. The study showed symptoms of threatened abortion are related to decreased concentrations of Pi, Mg, total protein and albumin and reduced activity of APt. Women who did not underwent miscarriage showed significantly higher Pi concentration compared to those who lost pregnancy, what might be of prognostic value. Threatened abortion was not considered to alter calcium homeostasis.

[Calcium, phosphorus and magnesium in pregnant women with primary hypertension].

Sixty five women were in the third trimester of pregnancy (29-40 weeks of gestation) submitted to the study including 35 with primary hypertension (the studied group) and 30 healthy (control group). The following parameters were measured in blood serum and urine from 24 hrs, collection: total Ca and Ca++, inorganic phosphorus (Pi) and magnesium. Generally accepted micromethods were used; Ca++ was measured using AVL type 9140 analyser. Women of the studied group presented mean blood pressure 164 +/- 14/106 +/- 9.7 mm Hg and did not have proteinuria and oedema. They presented decreased concentrations of total Ca (p < 0.004) and ionised Ca++ (p < 0.004), and an increase of Pi (p < 0.002) in blood serum. No differences in magnesium concentrations were found. Distinct decrease of calcium excretion in urine was found in hypertensive women (4.50 +/- 2.76 vs 6.60 +/- 3.4 mmol/24 hrs, p < 0.024). No alterations in phosphorus and magnesium urine excretion were observed in women with hypertension (women of both groups had the same volume of 24 urine). Our study concludes the main alterations in calcium-phosphorus-magnesium homeostasis in pregnant women with primary hypertension are the calcium homeostasis alterations. Phosphorus homeostasis is less affected while magnesium distribution does not change. Hypocalciuria might be related to impaired glomerular filtration in this pathology in pregnancy. Hypocalciuria and lowered serum concentrations of total Ca and ionised Ca++ might prove general deficiency of this element in pregnancy complicated by primary hypertension.

[Neonatal outcome depending on the mode of delivery and fetal presentation in twin gestation].

A retrospective analysis of 301 twin deliveries managed at The Second Department of Obstetrics and Gynecology, Warsaw Medical Academy, from January 1, 1986 to December 31, 1995 was undertaken in order to investigate the impact of the mode of delivery and twin presentation on neonatal outcome. Vertex presentation of both twins was the most common with an incidence of 47.5% followed by vertex-non-vertex (27.6%) and nonvertex presentation of the first twin (24.9%). 186 (61.8%) patients delivered vaginally, while 115 (38.2%) women underwent caesarean section including 6 operations performed after the vaginal delivery of the first twin. In vertex presentation of the first twin and breech second twin there was no significant difference in neonatal outcome measured by 5-minute Apgar score and birth trauma incidence between second twins delivered vaginally and second twins delivered by caesarean section. Vaginal delivery with internal podalic version of the second twin in vertex-transverse presentations was related to increased risk of lower 5-minute Apgar score and increased risk of birth trauma occurrence compared to caesarean section. Time interval between vaginal delivery of twins had no significant impact on neonatal outcome.

[Lipid metabolism in women with threatened abortion].

The study group consisted of 130 subjects: 50 healthy nonpregnant, 35 healthy women in the I trimester of gestation (gestational age 6-15 weeks) and 45 patients with symptoms of threatened abortion (the same gestational age). In the latter group pain and bleeding ceased after hormonal treatment and spasmolytic drugs. Serum blood concentration of following compounds were determined: total lipids, LDL fraction, total cholesterol, phospholipids, triglycerides, HDL and LDL cholesterol fractions. Threatened abortion had changed lipids profile; diminished concentrations of LDL fraction, total cholesterol, LDL cholesterol fraction and phospholipids were observed. Levels of total lipids, phospholipids and triglycerides++ in blood serum of healthy pregnant women in the I trimester of gestation were higher than in nonpregnant women.

[Homeostasis of calcium-phosphorus-magnesium in women with pregnancy induced hypertension].

Study group consisted of 63 women in the III trimester of pregnancy (gestational age 29-40 weeks). 32 subjects with PIH (investigated group) were compared to control group consisted of 30 healthy patients with uneventful course of gestation. Women with PIH had no proteinuria nor oedema, their mean blood pressure remained at the level of 161 +/- 16.7/98 +/- 12.8 mm Hg. Concentration of calcium, phosphorus and magnesium in serum blood and urine were determined. It was stated that due to renal impairment observed during PIH, calcium urine excretion and calcium concentration in blood serum are decreased while serum inorganic phosphorus levels are increased. No changes in magnesium and ionised calcium homeostasis were seen in the course of PIH.

[Evaluation of fetal condition in pregnancy complicated by hypertension--biochemical assessment of amniotic fluid. I. Protein and lipid components and kidney maturation].

Sixty two samples of amniotic fluid were submitted to biochemical investigation including 31 samples from women with pregnancy complicated by hypertension (studied group with mean blood pressure 165 +/- 15/95 +/- 5 mmHg) and 31 samples deriving from healthy pregnant women (control group with mean blood pressure 118 +/- 10/74 +/- +/- 9 mmHg). In the studied group pregnancy induced hypertension, primary hypertension and nephrogenic hypertension scored 58%, 32% and 10% of cases respectively. Both investigated and control groups consisted of pregnant women with the same gestational age of 37 +/- 2 weeks (34-40 weeks). The following parameters of amniotic fluid were measured: 1) total protein, 2) albumin, 3) beta-lipoprotein, 4) cholesterol, 5) uric acid, 6) urea, 7) creatinine. Micromethods were used. Amniotic fluid deriving from women with pregnancy complicated by hypertension showed decreased concentrations of total protein, albumin and beta-lipoprotein. In pregnancy complicated by hypertension kidneys of the fetuses were estimated to be as mature as in the normal pregnancy within the same gestational age.

[Evaluation of fetal condition in pregnancy complicated by hypertension--biochemical assessment of amniotic fluid. II. Enzymes].

Sixty two samples of amniotic fluid were submitted to biochemical investigation including 31 samples from women with pregnancy complicated by hypertension (studied group with blood pressure -65 +/- 15/95 +/- 5 mm Hg) and 31 samples deriving from healthy pregnant women (control group with mean blood pressure 118 +/- 10/74 +/- +/- 9 mm Hg). The following parameters of amniotic fluid were measured: 1) aminotransferases: alanine AlAT and aspartate AspAT, 2) alkaline phosphatase (APt) and its thermostable isoenzyme (APh), 3) ceruloplasmin (Crlp), 4) alpha-amylase (alpha-Amy). The study showed pregnancy complicated by hypertension is related to fetal salivary gland's immaturity presenting decreased activity of alpha amylase in amniotic fluid. Amniotic fluids deriving from women with pregnancy complicated by hypertension showed normal activities of AlAT, AspAT, APt, APh and Crlp.

[Evaluation of fetal condition in pregnancy complicated by hypertension--biochemical assessment of amniotic fluid. III. Acid-base balance].

Sixty two samples of amniotic fluid, collected by ultrasound guided amniocentesis, were submitted to biochemical investigation including 31 samples from women with pregnancy complicated by hypertension (studied group) and 31 samples deriving from healthy pregnant women (control group with). The following parameters of acid-base balance were measured in amniotic fluids of both groups: pH, pCO2, base deficiency, standard HCO3 and total CO2. Corning device type 168 was used. Distinct metabolic-respiratory acidosis was present in amniotic fluids of studied group showing the decrease of a pH, pO2, standard HCO3 values and an increase of CO2 values and base deficiency. Authors believe in pregnancy complicated by hypertension biochemical environment of intrauterine fetal development with regard to acid-base balance is highly unfavourable.

[The effect of total estrogens and lactogen hormone on lipid metabolism in women during normal pregnancy].

Lipids parameters and total oestrogen and HPL levels were estimated in blood serum. Investigated group consisted of 45 women with uneventful course of pregnancy. All pregnant women were in the gestational age between 29 and 40 weeks. This is positive correlation increased concentration of total lipids, LDL fraction, phospholipids, triglycerids and raising of total oestrogens. High concentration of total cholesterol, LDL cholesterol fraction and phospholipids were observed at the same time as increased levels of HPL. We suggest that multivariative hormonal changes during uncomplicated course of gestation could be the cause of modificated lipids profile.

[Bile acids in blood serum of women during normal pregnancy, early puerperium and in the neonate].

Total bile acids in serum blood samples from 325 subjects were estimated. Study group consisted of 50 nonpregnant women, 40-in the I trimester, 50-in the II and 100-in the III trimester of gestation, 55 patients in the third day of puerperium and 30 newborn infants (cord serum). All women were healthy, their age varied between 20 and 36 years. Children were mature, born in good condition (Apgar score > 8 points). Bile acids concentration were determined using enzymatic method with reagent kits by Nycomed Pharme, Norway. In the course of pregnancy continuous increase of investigated compounds was observed. The concentration of bile acids in puerperium was lower than in the III trimester of pregnancy and equal to that determined in cord serum. Authors conclude that during normal, uneventful course of gestation symptomless, benign intrahepatic cholestasis occurs.

[Fetal metabolism in post term pregnancy based on biochemical investigations of amniotic fluid. IV. Ion composition].

Concentrations of calcium, sodium, magnesium, calcium (total and ionised) and inorganic phosphorus were determined in amniotic fluid. Samples were taken from patients between 42-43 week of gestation (investigated group) and between 38 and 40 week (control group). Micro-methods, generally acknowledged in laboratories of clinical biochemistry were used. In the protracted pregnancies increase of magnesium levels and decrease of sodium levels were observed. No differences in concentrations of calcium, calcium (total and ionised) and inorganic phosphorus between investigated and control group were noted. Independently of the duration of pregnancy, near term or post term, ionised calcium constituted 90% of total calcium in amniotic fluid.

[Fetal metabolism in post-term pregnancy based on biochemical examinations of amniotic fluid. V. Glucose, bilirubin, H+ ions, hormones and tests of lung maturation].

Concentrations of glucose, bilirubin, H+ ions, estriol, HPL were determined in the samples of amniotic fluid from post term and near term pregnancies. Investigated group consisted of samples taken between 42-43 week of gestation, control group between 38-40 week. In both groups biochemical tests of pulmonary maturation--Lectin/Sphingomyelin ratio, foam test, 650 nm absorbance were carried out. In the diagnosis of post term pregnancy glucose concentrations, oestrogens, HPL, 650 nm adsorption, foam test and L/S ratio had proper diagnostic value. No differences were observed in bilirubin concentrations.

[Activity of alpha-amylase in serum and urine of pregnant women with diabetes mellitus type I].

The investigations covered 33 women in the III trimester of pregnancy with diagnosed, insulin-dependent diabetes mellitus, and 108 healthy women in the control group. The alpha-amylase activity was measured in the blood-serum and urine samples using the Caravay technique. An increased activity was demonstrated in the blood-serum samples in the examined group. The values were not related to the levels of glycemia. The urinary alpha-amylase activity was similar to that in the control patients. No coincidence between the activity and glycemia or acetone levels could be demonstrated.

Carbohydrate metabolism in the course of intrahepatic cholestasis in pregnancy.

Glucose metabolism was evaluated in pregnant women with clinically and biochemically demonstrated intrahepatic cholestasis. Laboratory investigations included measurements of serum glucose concentrations on fasting and 2 hours after breakfast, the glucose tolerance test (100 gm oral glucose load), and 24-hour glycemia profile. All patients were admitted to the II Department of Obstetrics and Gynecology, Institute of Obstetrics and Gynecology of the Medical School in Warsaw, Poland. None of the patients exhibited manifest diabetes mellitus or had any clinical history suggestive of previous diabetes. The serum samples collected 2 hours after breakfast demonstrated higher glucose concentrations in women with intrahepatic cholestasis when compared with healthy control subjects. The glucose tolerance tests demonstrated consistently higher concentrations of glucose in blood serum samples after loading in the study group. The 24-hour glycemia profile showed greater glucose concentrations in serum samples collected 2 hours after breakfast and after supper. These results suggest that in the course of cholestasis in pregnancy, visible changes occur in the carbohydrate metabolism of the pregnant woman.
