Role of anion gap and different electrolytes in hypertension during pregnancy (preeclampsia).

The present study was designed to determine the changes in serum sodium, anion gap, different antioxidants and free radicals in preeclamptic patients and control subjects. Serum sodium, chloride, bicarbonate, calcium, potassium and magnesium were estimated and anion gap was determined in 100 proteinuric hypertensive and 100 normotensive pregnant women. Mean serum sodium, chloride and bicarbonate level (133.26 +/- 13.1, 104.97 +/- 11.37, and 22.01 +/- 4.66 mEq/l, respectively) were significantly higher in proteinuric hypertensive women as compared to controls (125.85 +/- 10.4, 101.90 +/- 6.3, 19.34 +/- 3.21 mEq/l, respectively) whereas anion gap level (6.28 +/- 16.147) was nonsignificantly higher in proteinuric hypertensive as compared to normotensive (4.61 +/- 11.84). Total serum sodium concentration increases in preeclamptic subjects, the exact distribution of serum sodium in various compartments of the body are not clear and correlation of serum sodium and anion gap with proteinuria is also not known. The levels of different antioxidants were decreased in preeclamptic patients as compared to the controls while the level of free radicals elevated in preeclamptic subjects as compared to controls. In our study, anion gap level was found to be rather non-significantly higher in proteinuric hypertensive women as compared to normotensive women.

Alterations in gallbladder emptying and bile retention in the absence of changes in bile lithogenicity in postmenopausal women on hormone replacement therapy.

The role of female sex hormones in the pathogenesis of gallstones is well established. Pregnancy, contraceptive use, estrogen replacement therapy in postmenopausal women, and estrogen therapy in men for the treatment of prostatic carcinoma have been found to be associated with increased risk of cholesterol gallstones. Alterations in gallbladder emptying and in bile lithogenicity in postmenopausal women receiving hormone replacement therapy (HRT) have not been studied to date. The present study was undertaken to study the effect of HRT on gallbladder emptying and bile lithogenicity. Sixteen postmenopausal women were included in the study. None of the patients had gallstone disease and none had received prokinetic drugs, such as, erythromycin, metoclopramide, domperidone or cisapride, aspirin, and nonsteroidal antiinflammatory drugs. Gallbladder emptying (n = 16), bile microscopy (n = 7), cholesterol saturation index (CSI) (n = 7), and nucleation time (n = 7) were studied before and 3 months after HRT (conjugated estrogen, 0.625 mg, + medroxyprogesterone acetate, 2.5 mg, everyday). Fasting and residual volumes increased (fasting volume, 18.2 +/- 2.2 mL pre-HRT vs 27.6 +/- 3.2 mL post-HRT, P = 0.0003; residual volume, 3.9 +/- 0.6 mL pre-HRT vs 10.3 +/- 2.0 mL post-HRT, P = 0.00009) and ejection fraction decreased (78.2 +/- 2.5% pre-HRT vs 62.2 +/- 3.8% post-HRT; P = 0.0017) after 3 months of HRT. There was no change in CSI (2.32 +/- 0.36 pre-HRT vs 2.60 +/- 0.51 post-HRT; P = NS) or in nucleation time (19.0 +/- 1.2 days pre-HRT vs 17.6 +/- 1.3 days post-HRT; P = NS). None of the bile samples either pre-HRT or post-HRT showed cholesterol monohydrate crystals. Though impairment of gallbladder emptying occurs in the short term with HRT in postmenopausal women, there is no change in CSI and nucleation time.

Lipid peroxidation and vitamin E status in gestational diabetes mellitus.

AIM: To investigate any correlation between plasma levels of lipid peroxides, antioxidant nutrient (alpha-tocopherol) and oxidized high-density lipoprotein (HDL) in patients with gestational diabetes and those with a normal pregnancy and the incidence of pre-eclampsia. METHODS: Sixty pregnant women attending an antenatal clinic were recruited for the study and were divided into two groups. Thirty women with gestational diabetes mellitus were recruited in the study group. The glucose-tolerance-test criteria, using 100 g of glucose taken orally, as laid down by the American College of Obstetricians and Gynecologists (1994) for diagnosis of gestational diabetes mellitus was used. Thirty gestation-matched pregnant women with normal glucose tolerance test results were recruited as controls. A 10 mL venous blood sample was collected from each subject at the time of recruitment and thereafter at 4 week intervals until the time of delivery. Samples were analyzed for malondialdehyde thiobarbituric acid reactive, oxidized HDL-cholesterol and alpha-tocopherol. The incidence of pre-eclampsia and its correlation with antioxidant and lipid peroxide levels were compared in both the groups. RESULTS: Ten subjects out of 30 in the study group and three subjects out of 30 in the control group developed pre-eclampsia. The incidence of preterm labor in both the groups was same (16.66%). The mean lipid peroxide level was lower in the study group at recruitment and later the levels kept falling, whereas levels of alpha-tocopherol and oxidized-HDL were higher in the study group and kept on rising at follow up. CONCLUSION: Gestational diabetes is not associated with increased levels of lipid peroxides and decreased levels of alpha-tocopherol.

Pregnancy with acute intermittent porphyria: a case report and review of literature.

Acute intermittent porphyria (AIP) is an inherited disorder characterized by partial defects in the heme biosynthetic pathway. Although its association with pregnancy is rare, it presents the obstetrician with challenging problems especially in labor management, as one of the obstetrical life line drugs (methergin) is contraindicated for use in these patients. We hereby present a case of AIP who had an uneventful pregnancy with a good neonatal outcome.
