Full textThe aim of the present study was to clarify if the pulmonary protective effects of AT III in LPS-induced ARDS can be attributed to a stimulation of the pulmonary vascular release of PGI2. The pulmonary vascular release of big ET-1 and ET-1 under septic conditions and the possible influence of AT III was to be investigated. To this end, we used the model of the isolated perfused rat lung. Exposure of the lung to LPS increased the release of 6-Keto-PGF1(, the stable metabolite of PGI2, 1.6fold and the production of TxB2, the stable metabolite of TxA2, 2.9fold compared with control lungs. The release of ET-1 increased 1.6fold under LPS, whereas the concentration of big ET-1 was unchanged. The application of AT III had no effect on the release of PGI2 and TxA2. The effects following combined application of LPS and AT III were similar to the effects of LPS alone. Compared with controls, AT III, at 2 U/ml, increased the perfusate levels of big ET-1 and ET-1 1.7fold and 1.2fold, respectively; the administration of 5 U/ml AT III raised big ET-1 and ET-1 1.6fold and 1.3fold, respectively. Combined application of LPS and AT III resulted in a 2.6fold rise of big ET-1 levels compared with controls, whereas concentrations of ET-1 did not differ from those in the presence of LPS or AT III alone. Cicaprost, a stable PGI2 analogue, affected neither the basal nor the AT III plus LPS-stimulated release of big ET-1 and ET-1. Nicardipin, an L-type calcium channel blocker, heparin and N-acetyl heparin, a heparin derivative devoid of AT III affinity, each antagonized completely the AT III-stimulated increase in big ET-1 and ET-1 levels. Staurosporin, an inhibitor of protein kinase C, and genistein, an inhibitor of tyrosine kinases, did not influence the AT III effects on endothelins. CONCLUSIONS: In ARDS, the well-known rise in plasma PGI2 in response to AT III obviously originates from non-pulmonary sources. PGI2 does not suppress the pulmonary ET-1 secretion; therefore, this mechanism seems not involved in the AT III-induced lung protection during septic ARDS. The AT III-mediated stimulation of the release of pulmonary endothelins is of potential pathophysiological relevance, because it may blunt the protective effects of AT III in ARDS. In the intact rat lung, this stimulatory effect of AT III is mediated neither by protein kinase C nor by tyrosine kinases. Moreover, the observed effect of AT III on pulmonary endothelins is based on calcium influx through L-type calcium channels and depends on the intracellular calcium activity. The equipotency of heparin and N-acetyl heparin in inhibiting the AT III action demonstrates that direct binding of AT III is not essential for the blocking effect of heparins. This fact points to additional involvement of an IP3-dependent intracellular calcium release.

Full textUnfractionnated heparin (UFH), low molecular weight heparins (LMWH), and fondaparinux are used therapeutically as anticoagulants. They potentiate antithrombin (AT): a physiological inhibitor of coagulation. Their therapeutic use is associated with a major risk of bleeding. Currently, protamine sulfate is the only antidote available for UFH. It is partially effective for LMWH, and has no effect against fondaparinux, which has no antidote. So, we propose modified inactive AT, but able to bind heparin molecules as antidote of these heparins. These molecules would compete with plasmatic AT for binding to heparins, and neutralize their anticoagulant effect. To produce that AT, we realized a genetic approach and a chemical approach. In the first approach, we expressed the variant AT-N135Q-Pro394 that had an anti-Xa or anti-IIa activity below 0.02% in the presence of heparins, and heparin affinity three times higher, compared to the plasmatic AT. In the chemical approach, we modified the plasmatic AT by 2,3-butanedione (AT-BD), a chemical reagent for arginin’s characterization. The AT-BD had a moderate loss of anticoagulant activity, and a heparin affinity 20 times higher, compared to the plasmatic AT. Despite these differences in biochemical properties, these two modified AT neutralize similarly heparins in vitro and in a mouse model. Moreover, unlike protamine sulfate, our antidotes had not an intrinsic anticoagulant effect in activated partial thromboplastin test. Thus, this PhD-work offers the first and the only specific antidote described to fondaparinux, and it can be used too alternatively for all anticoagulant heparins

Full textTiivistelmä Tutkimuksessa arvioitiin osaa yleisimmän pahanlaatuisen imukudossyövän eli lymfooman, diffuusin suurisoluisen B-solulymfooman, hoidon haasteista. Osa potilaista saa ensilinjan hoidon jälkeen joko paikallisen tai aivoston alueen taudin uusiutuman. Uusiutuneen taudin hoito on haasteellista, ja hoitoyrityksistä huolimatta osa potilaista kuolee tautiinsa. Solunsalpaajille resistentti tauti on myös yksi haastavista hoitotilanteista, ja osa potilaista kärsiikin hoitojen läpi etenevästä taudista. Antioksidatiivisia entsyymejä, kuten peroksiredoksiineja ja tioredoksiinia, arvioitiin ennusteellisina ja ennakoivina merkkiaineina diffuusissa suurisoluisessa B-solulymfoomassa. Peroksiredoksiini VI:n korkea sytosolinen ilmaantuvuus korreloi tavallista huonompaan diffuusin suurisoluisen B-solulymfooman ennusteeseen. Tioredoksiinin hiljentäminen lymfoomasoluviljelyssä paljasti sen mahdollisen ennakoivan merkityksen hoitoon liittyvässä päätöksenteossa. Solut herkistyivät tiodredoksiinin hiljentämisen vuoksi doksorubisiinille, jota käytetään laajalti diffuusin suurisoluisen B-solulymfooman solunsalpaajahoidoissa. Etoposidi, joka on huomattavasti myrkyllisempi solunsalpaaja, päinvastoin tappoi enemmän tavallisia diffuusia suurisoluisia B-solulymfoomaa edustavia soluja kuin doksorubisiini. Potilaat, joilla oli korkea tioredoksiinin määrä taudin diagnostisessa vaiheessa, hyötyivät etoposidia sisältävästä korkea-annoshoidosta sekä autologisesta kantasolusiirrosta. Näille potilaille ei kehittynyt kantasolusiirron jälkeisiä taudin uusiutumia kuin taas niitä kehittyi potilaille, joilla oli tioredoksiini negatiivinen. Antitrombiini III:a on ehdotettu soveltuvaksi aikaisempien tutkimusten perusteella aivoston lymfooman merkkiaineeksi aivo-selkäydinnesteestä. Tässä tutkimuksessa antitrombiini III:n määrää mitattiin potilailta, joilla oli aivoston lymfooma tai neurologinen sairaus. Korkeat konsentraatiot antitrombiini III:a aivo-selkäydinnesteessä kuitenkin vain heijastivat veri-aivoesteen vuotamisen määrää, ja näin ollen antitrombiini III:a ei tulisi käyttää kliinisessä käytössä

Full textThe aim of this study was to evaluate differences in maternal and neonatal outcomes in pregnancies complicated by inherited thrombophilias between patients with and without venous thromboembolism. Despite increasing evidence in the literature indicating an association between inherited thrombophilias and adverse obstetric outcomes, doubts remain whether thrombophilic patients with venous thromboembolism present poorer maternal and neonatal outcomes than thrombophilic patients without venous thromboembolism. In this retrospective, observational and comparative study, 66 pregnant women with inherited thrombophilias, including 33 with venous thromboembolism and 36 without thromboembolism, were investigated. The main end-points analyzed were severe pre-eclampsia, placental abruption, fetal growth restriction, stillbirth, preterm delivery, and maternal hemorrhagic complications. The congenital thrombophilias included in this study were factor V Leiden (FVL), prothrombin G20210A mutation, C677T mutation in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene, protein S deficiency, protein C deficiency, and antithrombin deficiency. The two groups were similar in terms of population characteristics. The frequency of maternal and fetal/neonatal complications was similar in the two groups: severe pre-eclampsia (P=0.097), placental abruption (P=0.478), fetal growth restriction (P=0.868), stillbirth (P=0.359), preterm delivery (P=0.441), and maternal hemorrhagic complications (P=0.478). This study concluded that venous thromboembolism in thrombophilic patients does not worsen maternal or neonatal outcomes when compared to thrombophilic patients without venous thromboembolism.
