Efficacy and tolerance of recombinant tissue-type plasminogen activator in patients with thrombotic or embolic occlusions of leg-arteries     

Prof. Dr. F. A. Spengel  G. Küffer  H. Stiegler 《Journal of molecular medicine (Berlin, Germany)》1993,71(4):323-326

Summary The efficacy and safety of recombinant tissue-type plasminogen activator (rt-PA) was evaluated in 46 patients with thrombembolic arterial occlusions in leg arteries. rt-PA was given over 1–4 h with a maximum dose of 18 mg. The effect of rt-PA treatment was determined as patency of the occluded arteries in 44 different patients 14 days after treatment. In 41 patients at least one artery was recanalized (93%) by rt-PA, and in almost half of these patients (48%) no residual stenosis were detected after the lytic treatment. A slight residual stenosis was detected in 29% of the patients and a severe residual stenosis in 21%. An additional treatment with percutaneous transluminal angioplasty was performed in 23 of the 44 patients and successful in 21 (91%). In 8 patients an addition catheter-embolectomy was performed. No difference in patency rate was detected between patients with thrombotic and those with embolic occlusions. The age of the occlusion influenced the patency rate; occlusions under the age of 5 weeks showed a patency rate of 96% compared to 82% in older occlusions. The length of the occlusion did not have any influence on the outcome of the rt-PA treatment. From the results of this open study we conclude that a dose of up to 18 mg of rt-PA is both safe and effective in the treatment of thromboembolic occlusions in leg arteries.Abbreviations rt-PA recombinant tissue-type plasminogen activator - GGT gamma-glutamyltransferase - SGOT aspartate aminotransferase - SGPT alanine aminotransferase - LDH lactate dehydrogenase - PTA percutaneous transluminal angioplasty Dedicated to Prof. Dr. N.

The aim of this study was to evaluate the embryo-fetal development toxicity of honokiol microemulsion. The drug was intravenously injected to pregnant SD rats at dose levels of 0, 200, 600 and 2000 μg/kg/day from day 6–15 of gestation. All the pregnant animals were observed for body weights and any abnormal changes and subjected to caesarean-section on gestation day (GD) 20; all fetuses obtained from caesarean-section were assessed by external inspection, visceral and skeletal examinations. No treatment-related external alterations as well as visceral and skeletal malformations were observed in honokiol microemulsion groups. There was no significant difference in the body weight gain of the pregnant rats, average number of corpora lutea, and the gravid uterus weight in the honokiol microemulsion groups compared with the vehicle control group. However, at a dose level of 2000 μg/kg/day, there was embryo-fetal developmental toxicity observed, including a decrease in the body length and tail length of fetuses. In conclusion, the no-observed–adverse-effect level (NOAEL) of honokiol microemulsion is 600 μg/kg/day, 75 times above the therapeutic dosage and it has embryo-fetal toxicity at a dose level of 2000 μg/kg/day, which is approximately 250 times above the therapeutic dosage.  相似文献

Intravenous rt-PA in patients with ischaemic stroke and renal dysfunction     

P. Sobolewski  G. Kozera  R. Kaźmierski  S. Michalak  W. Szczuchniak  M. Śledzińska-Dźwigał  W.M. Nyka 《Clinical neurology and neurosurgery》2013

Objective

Renal dysfunction (RD) increases risk for ischaemic stroke (IS). The impact of RD on the effects of iv-thrombolysis in the Caucasian population has not been fully determined.

Aims

To evaluate the associations between RD and the outcome of iv-thrombolysis in Caucasian patients with IS.

Methods

The observational, multicentre study included 404 patients with IS who were treated with iv-thrombolysis. RD was defined as estimated glomerular filtration rate ≤60 ml/min/1.73 m². Outcome was assessed with modified Rankin Score at 3 months after the stroke onset.

Results

Medians baseline NIHSS score did not differ between groups of patients with and without RD (12.0 vs. 11.0 pts, p = 0.33). Unfavourable outcome was found in 52.1% of patients with and in 41.2% of patients without RD (p = 0.05), mortality was higher in patients with RD (29.9% vs. 14.3%, p < 0.001), and the presence of haemorrhagic transformation (HT) did not differ between the groups (17.1% vs. 17.1% respectively, p = 0.996). A multivariate analysis showed no impact of RD on the unfavourable outcome (OR 0.98; 95%CI 0.88–1.10), mortality (OR 0.92; 95%CI 0.81–1.05) or presence of HT (OR 1.03; 95%CI 0.90–1.18).

Conclusions

We found no impact of RD on the safety and efficacy of iv-thrombolysis in Caucasian patients with IS.  相似文献
