Twenty-four epileptic women were followed-up during late pregnancy, labor, and early puerperium in order to detect possible alterations in serum protein binding of antiepileptic drugs (AEDs). The total and free concentrations of carbamazepine (CBZ), phenytoin (PHT), and valproate (VPA) in maternal serum were measured. In addition, the concentrations of albumin, alpha 1-acid glycoprotein (AGP), and free fatty acids (FFA) were also measured. Total AED concentrations during labor were influenced by changes in drug dosages; total PHT increased during the first puerperal weeks. During labor the free fraction of CBZ remained stable, whereas PHT and particularly VPA free fractions increased. This phenomenon was parallel to the increase in FFA concentration; FFA concentrations decreased again during the first days postpartum. Albumin and AGP concentrations were low during pregnancy and labor, and increased after delivery. The total umbilical CBZ and PHT concentrations were not significantly different from maternal concentrations. The total VPA concentration in umbilical serum was significantly higher than that in maternal serum. The free fraction of CBZ was higher and that of PHT and VPA lower in umbilical than in maternal serum at delivery. Umbilical cord serum had a higher albumin but a lower AGP and FFA concentration than maternal serum. The changes in PHT and particularly VPA free fraction associated with changes in FFA concentration should be considered when assessing the total concentration of these drugs in maternal and umbilical serum. 相似文献

Levodopa, bromocriptine and selegiline modify cardiovascular responses in Parkinson's disease 总被引:2,自引:0,他引:2

Autonomic nervous system (ANS) involvement is frequently found in Parkinson's disease (PD), but its causal relationship to
the disease itself and its medication is unclear. We evaluated the effects of PD medications on cardiovascular ANS functions.
Heart rate (HR) responses to normal and deep breathing, the Valsalva manoeuvre and tilting, and blood pressure (BP) responses
to tilting and isometric work were measured prospectively in 60 untreated PD patients randomised to receive either levodopa
(n=20), bromocriptine (n=20) or selegiline (n=20) as their initial treatment. The results were compared with those of 28 healthy controls. The responses were recorded
at baseline, after 6 months on medication and following a 6-week washout period. At baseline HR responses to normal breathing,
deep breathing and tilting were already lower and the fall in the systolic BP immediately and at 5 min after tilting was more
pronounced in the PD patients than in the controls. Six months' levodopa treatment diminished the systolic BP fall after tilting
when compared to baseline, whereas bromocriptine and selegiline increased the fall in systolic BP after tilting and selegiline
diminished the BP responses to isometric work. The BP responses returned to the baseline values during the washout period.
The drugs induced no change in the HR responses. Thus PD itself causes autonomic dysfunction leading to abnormalities in HR
and BP regulation and the PD medications seem to modify ANS responses further. Bromocriptine and selegiline, in contrast to
levodopa, increase the orthostatic BP fall and supress the BP response to isometric exercise reflecting mainly impairment
of the sympathetic regulation.

Is there any link between insulin resistance and inflammation in established preeclampsia? 总被引:5,自引:0,他引:5
Kaaja R Laivuori H Pulkki P Tikkanen MJ Hiilesmaa V Ylikorkala O 《Metabolism: clinical and experimental》2004,53(11):1433-1435
Both insulin resistance and inflammation may contribute to the onset of preeclampsia. They also could be interrelated. We studied the relationship between inflammatory cytokines and markers of insulin resistance. During their third trimester, 22 proteinuric preeclamptic women and 16 normotensive controls underwent intravenous glucose tolerance test (minimal model). Preeclamptic women were more insulin-resistant (P = .009), and they had higher levels of serum soluble tumor necrosis alpha receptor II (TNFalpha RII) (P = .002), triglycerides (P = .006), uric acid (P = .001), and leptin (P = .002) than did the controls. However, the study groups did not differ in serum TNFalpha, C-reactive protein (CRP), interleukin-6 (IL-6), sex hormone-binding globulin (SHBG), and high-density lipoprotein-2 (HDL(2))-cholesterol. In multiple regression analysis only SHBG (P = .01) and triglycerides (P = .0036) were associated with insulin sensitivity independently of body mass index (BMI), weight gain, HDL(2)-cholesterol, CRP, TNFalpha, and TNFalpha RII, IL-6, and leptin. We conclude that insulin resistance and the inflammatory markers studied were not associated in established preeclampsia. 相似文献

Common chronic infections including those caused by cytomegalovirus (CMV), herpes simplex viruses (HSV), Helicobacter pylori and Chlamydia pneumoniae have previously been related to increased risk of coronary heart disease (CHD). We investigated the association between serology of these chronic infections and coronary bypass graft occlusions in 61 patients. As a result, IgG seropositivity rate against H. pylori was higher among patients without occlusion (82%) than in those with occlusion (45%) or apparently healthy controls (57%) (p = 0.004 and p = 0.008, respectively). In conclusion, H. pylori infection, as judged by IgG seropositivity, is associated with lower occurrence of venous bypass graft occlusion in patients with CHD and may thus be connected with better outcome and prognosis of CHD patients after bypass graft surgery. 相似文献

Aims/hypothesis Our aim was to study whether pre-eclampsia and pregnancy-induced hypertension are predictors of diabetic nephropathy in type
1 diabetic women.
Materials and methods A total of 203 type 1 diabetic women, who were pregnant between 1988 and 1996 and followed at the Department of Obstetrics
and Gynaecology in Helsinki, were re-assessed after an average of 11 years within the nationwide, multi-centre Finnish Diabetic
Nephropathy Study. Diabetic nephropathy was defined as microalbuminuria, macroalbuminuria or end-stage renal disease.
Results Patients with prior pre-eclampsia had diabetic nephropathy more often than patients with a normotensive pregnancy (diabetic
nephropathy vs normal albumin excretion rate: 41.9% vs 8.9%; p<0.001), whereas patients with a history of pregnancy-induced hypertension did not (10.3% vs 8.9%; p=0.81). CHD was more prevalent in patients with a history of pre-eclampsia than in patients with a normotensive pregnancy
(12.2% vs. 2.2%; p=0.03). Pre-eclampsia (odds ratio [OR] 7.7, 95% CI 1.6-36.1; p=0.01) and HbA1c (OR 2.0, 95% CI 1.1-3.8; p<0.05) were associated with incident diabetic nephropathy even when adjusted for follow-up time, BMI, smoking, diabetes duration
and age.
Conclusions/interpretation These data suggest that a history of pre-eclamptic pregnancy but not pregnancy-induced hypertension is associated with an
elevated risk of diabetic nephropathy.

Venous thromboembolism remains an important cause of maternal mortality. In a randomised open study, 44 pregnant women with confirmed previous or current thromboembolism were randomised to receive either low-molecular-weight heparin, dalteparin (N = 21) once daily subcutaneously or unfractionated sodium heparin (UF heparin, N = 23) twice daily subcutaneously for thromboprophylaxis during pregnancy and puerperium. Bone mineral density (BMD) in the lumbosacral spine was measured with dual X-ray absorptiometry (DEXA) 1, 6, 16, 52 weeks and, if possible, 3 years after delivery. BMD values were also compared with those of healthy, delivered women (N = 19). Mean BMD of the lumbar spine was significantly lower in the unfractionated heparin group compared with the dalteparin and with the control groups (repeated measures ANOVA p = 0.02). BMD in the dalteparin group did not differ from BMD of healthy delivered women. Multiple logistic regression analysis revealed that therapy was the only independent factor influencing BMD at weeks 16 and 52. Therefore we recommend use of dalteparin instead of UF heparin for long-term thromboprophylaxis during and after pregnancy. 相似文献

Bilateral subthalamic nucleus stimulation improves health-related quality of life in Parkinsonian patients 总被引:5,自引:0,他引:5
Erola T Karinen P Heikkinen E Tuominen J Haapaniemi T Koivukangas J Myllylä V 《Parkinsonism & related disorders》2005,11(2):89-94
Parkinson's disease (PD) is a common neurological disorder. Recently, bilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) has become an option in the treatment of severe PD. We measured the health-related quality of life (HRQoL) of 27 parkinsonian patients, who underwent a bilateral STN-operation. The instruments used for the evaluation of the HRQoL were the Parkinson's Disease Questionnaire (PDQ-39) and the Finnish version of the Nottingham Health Profile (NHP). We found that the quality of life significantly improved when measured with both HRQoL scales. Clinical improvement and improvement in HRQoL were positively correlated. 相似文献
