Unprecedented community containment measures were taken following the recent outbreak of COVID-19 in Italy. The aim of the study was to explore the self-reported future compliance of citizens with such measures and its relationship with potentially impactful psychological variables.. An online survey was completed by 931 people (18-76 years) distributed across the Italian territory. In addition to demographics, five dimensions were measured: self-reported compliance with containment measures over time (today, at 7, 14, 30, 60, 90, and 180 days from now) at three hypothetical risk levels (10, 50, 90% of likelihood of contracting the COVID-19), perceived risk, generalized anxiety, intolerance of uncertainty, and relevance of several psychological needs whose satisfaction is currently precluded.. The duration of containment measures plays a crucial role in tackling the spread of the disease as people will be less compliant over time. Psychological needs of citizens impacting on the compliance should be taken into account when planning an easing of the lockdown, along with interventions for protecting vulnerable groups from mental distress.. La apendicitis aguda (AA) es la urgencia quirúrgica abdominal más frecuente. No encontramos estudios específicos que evalúen el impacto de la pandemia causada por el coronavirus 2 (SARS-Cov-2) sobre la AA y su tratamiento quirúrgico. Analizamos la influencia de esta nueva patología sobre la AA.. Estudio observacional retrospectivo en pacientes intervenidos por AA desde enero hasta abril de 2020. Fueron clasificados según el momento de la apendicectomía, antes de la declaración del estado de alarma (Pre-COVID19) y después de la declaración del estado de alarma (Post-COVID19) en España. Se evaluaron variables demográficas, duración de la sintomatología, tipo de apendicitis, tiempo quirúrgico, estancia hospitalaria y complicaciones postoperatorias.. La pandemia por SARS-Cov-2 influye en el momento de diagnóstico de la apendicitis, así como en su grado de evolución y estancia hospitalaria. La peritonitis fue lo más frecuentemente observado. Una sospecha y orientación clínica más temprana, es necesaria para evitar un manejo inadecuado de este trastorno quirúrgico común.. The primary outcome is improvement in PaO. Findings will provide timely information on the safety, efficacy, and optimal dosing of t-PA to treat moderate/severe COVID-19-induced ARDS, which can be rapidly adapted to a phase III trial (NCT04357730; FDA IND 149634).. None.. The gut barrier is crucial in cirrhosis in preventing infection-causing bacteria that normally live in the gut from accessing the liver and other organs via the bloodstream. Herein, we characterised gut inflammation by measuring different markers in stool samples from patients at different stages of cirrhosis and comparing this to healthy people. These markers, when compared with equivalent markers usually measured in blood, were found to be very different in pattern and absolute levels, suggesting that there is significant gut inflammation in cirrhosis related to different immune system pathways to that seen outside of the gut. This provides new insights into gut-specific immune disturbances that predispose to complications of cirrhosis, and emphasises that a better understanding of the gut-liver axis is necessary to develop better targeted therapies.. La surveillance de l’intervalle QT a suscité beaucoup d’intérêt durant la pandémie de la COVID-19 en raison de l’utilisation de médicaments prolongeant l’intervalle QT et les préoccupations quant à la transmission virale par les électrocardiogrammes (ECG) en série. Nous avons posé l’hypothèse que la surveillance en continu de l’intervalle QT par télémétrie était associée à une meilleure détection des épisodes de prolongation de l’intervalle QT.. Nous avons introduit la télémétrie cardiaque en continu (TCC) à l’aide d’un algorithme de surveillance automatisée de l’intervalle QT dans nos unités de COVID-19. Les mesures automatisées quotidiennes de l’intervalle QT corrigé (auto-QTc) en fonction de la fréquence cardiaque maximale ont été enregistrées. Nous avons comparé la proportion des épisodes de prolongation marquée de l’intervalle QTc (QTc long), définie par un intervalle QTc ≥ 500 ms, chez les patients montrant une suspicion de COVID-19 ou ayant la COVID-19 qui avaient été admis avant et après la mise en place de la TCC (groupe témoin. La surveillance en continu de l’intervalle QT est supérieure à la norme de soins dans la détection des épisodes de QTc long et exige peu d’ECG. La réponse clinique aux épisodes de QTc long est sous-optimale.. Exposure to a model wildfire air pollution source modifies cardiovascular responses to HC challenge, suggesting air pollution sensitizes the body to systemic triggers.. Though the majority of HIV-infected adults who were on HAART had shown viral suppression, the rate of suppression was sub-optimal according to the UNAIDS 90-90-90 target to help end the AIDS pandemic by 2020. Nonetheless, the rate of immunological recovery in the study cohort was low. Hence, early initiation of HAART should be strengthened to achieve good virological suppression and immunological recovery.. Dust in Egyptian laying hen houses contains high concentrations of microorganisms and endotoxins, which might impair the health of birds and farmers when inhaled. Furthermore, laying hens in Egypt seem to be a reservoir for ESBL-producing Enterobacteriaceae. Thus, farmers are at risk of exposure to ESBL-producing bacteria, and colonized hens might transmit these bacteria into the food chain.. The lack of significant differences in the absolute changes and relative ratios of injury and repair biomarkers by contrast-associated AKI status suggests that the majority of mild contrast-associated AKI cases may be driven by hemodynamic changes at the kidney.. Most comparisons for different outcomes are based on very few studies, mostly low-powered, with an overall low CoE. Thus, the available evidence is considered insufficient to either support or refute CH effectiveness or to recommend one ICM over another. Therefore, further well-designed, larger RCTs are required.. PROSPERO database Identifier: CRD42016041953.. Untouched root canal at cross-section perimeter, the Hero 642 system showed 41.44% ± 5.62% and Reciproc R40 58.67% ± 12.39% without contact with instruments. Regarding the untouched area, Hero 642 system showed 22.78% ± 6.42% and Reciproc R40 34.35% ± 8.52%. Neither instrument achieved complete cross-sectional root canal debridement. Hero 642 system rotary taper 0.02 instruments achieved significant greater wall contact perimeter and area compared to reciprocate the Reciproc R40 taper 0.06 instrument.. Hero 642 achieved higher wall contact perimeter and area but, regardless of instrument size and taper, vital pulp during. The functional properties of the main mechanisms involved in the control of muscle Ca. This study showed that the anti-inflammatory effect of the iron-responsive product DHA in arthritis can be monitored by an iron-like radioactive tracer (. Attenuated vascular reactivity during pregnancy suggests that the systemic vasodilatory state partially depletes nitric oxide bioavailability. Preliminary data support the potential for MRI to identify vascular dysfunction in vivo that underlies PE. Level of Evidence 2 Technical Efficacy Stage 1 J. MAGN. RESON. IMAGING 2021;53:447-455.. La evaluación de riesgo es importante para predecir los resultados postoperatorios en pacientes con cáncer gastroesofágico. Este estudio de cohortes tuvo como objetivo evaluar los cambios en la composición corporal durante la quimioterapia neoadyuvante e investigar su asociación con complicaciones postoperatorias. MÉTODOS: Los pacientes consecutivos con cáncer gastroesofágico sometidos a quimioterapia neoadyuvante y cirugía con intención curativa entre 2016 y 2019, identificados a partir de una base de datos específica, se incluyeron en el estudio. Se utilizaron las imágenes de tomografía computarizada, antes y después de la quimioterapia neoadyuvante, para evaluar el índice de masa muscular esquelética, la sarcopenia y el índice de grasa visceral y subcutánea.. In this in vitro premature infant lung model, HF oscillation of BCPAP was associated with improved CO. Our results showed that HPC significantly promotes neurogenesis after MCAO and ameliorates neuronal injury.. Inflammatory markers are highly related to signs of systemic hypoperfusion in CS. Moreover, high PCT and IL-6 levels are associated with poor prognosis.. These findings indicate that Tetrapleura tetraptera fruit has a protective potential against stroke through modulation of redox and electrolyte imbalances, and attenuation of neurotransmitter dysregulation and other neurochemical dysfunctions. Tetrapleura tetraptera fruit could be a promising source for the discovery of bioactives for stroke therapy.

Acute kidney injury (AKI) is a critical complication among patients with acute coronary syndrome (ACS) undergoing invasive management. The value of adjunctive antithrombotic strategies, such as bivalirudin or unfractionated heparin (UFH) on the risk of AKI is unclear.. Among 7213 patients enrolled in the MATRIX-Antithrombin and Treatment Duration study, 128 subjects were excluded due to incomplete information on serum creatinine (sCr) or end-stage renal disease on dialysis treatment. The primary endpoint was AKI defined as an absolute (>0.5 mg/dL) or a relative (>25%) increase in sCr. AKI occurred in 601 patients (16.9%) treated with bivalirudin and 616 patients (17.4%) treated with UFH [odds ratio (OR): 0.97; 95% confidence interval (CI): 0.85-1.09; P = 0.58]. A >25% sCr increase was observed in 597 patients (16.8%) with bivalirudin and 616 patients (17.4%) with UFH (OR: 0.96; 95% CI: 0.85-1.08; P = 0.50), whereas a >0.5 mg/dL absolute sCr increase occurred in 176 patients (5.0%) with bivalirudin vs. 189 patients (5.4%) with UFH (OR: 0.92; 95% CI: 0.75-1.14; P = 0.46). By implementing the Kidney Disease Improving Global Outcomes (KDIGO) criteria, the risk of AKI was not significantly different between bivalirudin and UFH groups (OR: 0.88; 95% CI: 0.72-1.07; P = 0.21). Subgroup analyses of the primary endpoint suggested a benefit with bivalirudin in patients randomized to femoral access.. Among ACS patients undergoing invasive management, the risk of AKI was not significantly lower with bivalirudin compared with UFH.. clinicaltrials.gov NCT01433627.

Acute kidney injury (AKI) is not uncommon in patients undergoing transcatheter aortic valve replacement (TAVR).. We examined the incidence, predictors, and outcomes of AKI from the BRAVO 3 randomized trial.. The BRAVO-3 trial included 802 patients undergoing transfemoral TAVR randomized to bivalirudin vs. unfractionated heparin (UFH). The primary endpoint of the trial was Bleeding Academic Research Consortium (BARC) type ≥ 3b bleeding at 48 h. Total follow-up was to 30 days. AKI was adjudicated using the modified RIFLE (Valve Academic Research Consortium, VARC 1) criteria through 30-day follow-up, and in a sensitivity analysis AKI was assessed at 7 days (modified VARC-2 criteria). We examined the incidence, predictors, and 30-day outcomes associated with diagnosis of AKI. We also examined the effect of procedural anticoagulant (bivalirudin or unfractionated heparin, UFH) on AKI within 48 h after TAVR.. The trial population had a mean age of 82.3 ± 6.5 years including 48.8% women with mean EuroScore I 17.05 ± 10.3%. AKI occurred in 17.0% during 30-day follow-up and was associated with greater adjusted risk of 30-day death (13.0% vs. 3.5%, OR 5.84, 95% CI 2.62-12.99) and a trend for more BARC ≥ 3b bleeding (15.1% vs. 8.6%, OR 1.80, 95% CI 0.99-3.25). Predictors of 30-day AKI were baseline hemoglobin, body weight, and pre-existing coronary disease. AKI occurred in 10.7% at 7 days and was associated with significantly greater risk of 30-day death (OR 6.99, 95% CI 2.85-17.15). Independent predictors of AKI within 7 days included pre-existing coronary or cerebrovascular disease, chronic kidney disease (CKD), and transfusion which increased risk, whereas post-dilation was protective. The incidence of 48-h AKI was higher with bivalirudin compared to UFH in the intention to treat cohort (10.9% vs. 6.5%, p = 0.03), but not in the per-protocol assessment (10.7% vs. 7.1%, p = 0.08).. In the BRAVO 3 trial, AKI occurred in 17% at 30 days and in 10.7% at 7 days. AKI was associated with a significantly greater adjusted risk for 30-day death. Multivariate predictors of AKI at 30 days included baseline hemoglobin, body weight, and prior coronary artery disease, and predictors at 7 days included pre-existing vascular disease, CKD, transfusion, and valve post-dilation. Bivalirudin was associated with greater AKI within 48 h in the intention to treat but not in the per-protocol analysis.

Acute kidney injury (AKI) is an important complication of both diagnostic cardiac catheterization and percutaneous coronary intervention (PCI). A large body of evidence supports that AKI is related to volume of contrast used. Despite several measures are available to reduce the impact of contrast media on AKI, its incidence remains significant as other mechanisms of renal damage are involved. A new paradigm is established according to which bleeding prevention is at least as important as preventing recurrent ischemic events in the management of patients with acute coronary syndromes (ACS) undergoing an invasive approach. Periprocedural bleeding, which is consistently reduced by radial approach, is emerging as a risk factor for the development of AKI. Therefore, the role of vascular access as a measure to prevent AKI needs to be systematically assessed in randomized studies. To date, no prospective comparison on renal outcomes has been carried out in randomized trials between radial and femoral approach. The Minimizing Adverse hemorrhagic events by TRansradial access site and systemic Implementation of AngioX (MATRIX) trial (ClinicalTrials.gov identifier: NCT01433627) has been designed to test whether to minimize bleeding events by using radial access and bivalirudin, across the whole spectrum of patients with ACS undergoing PCI, will result in improved outcomes with respect to both ischemic and bleeding complications. The AKI-MATRIX sub-study will provide a unique opportunity to assess whether the advantages of radial approach may even contribute to the reduction of the risk of AKI in patients with ACS.

To evaluate the safety and efficacy of bivalirudin compared with heparin for preventing hemofilter occlusion during continuous venovenous hemofiltration (CVVH).. Prospective, randomized, double-blind study.. University-affiliated hospital.. Ten critically ill adults (median age 58 yrs, 70% male) with acute renal failure who, without anticoagulation, experienced hemofilter survival time of 24 hours or less during CVVH.. Patients were randomized to receive bivalirudin 2 mg/hour (five patients) or heparin 400 units/hour (five patients) administered prefilter into the extracorporeal circuit.. Patients had a median Acute Physiology and Chronic Health Evaluation (APACHE) II score of 24, Sequential Organ Failure Assessment (SOFA) score of 11, and reduced antithrombin activity (75.5 units/dl). Baseline characteristics were not significantly different between groups. Study drug was administered in 40 hemofilters (18 from bivalirudin-treated patients, 22 from heparin-treated patients). The primary efficacy outcome was hemofilter survival time, defined as the interval of time between commencement of CVVH with a new extracorporeal circuit (hemofilter) and hemofilter failure. Compared with no anticoagulation, the addition of bivalirudin or heparin significantly improved hemofilter survival time (mean ± SD 10 ± 5 hrs with no anticoagulation vs 22 ± 18 hrs with anticoagulation, p=0.0005). Hemofilter survival time was significantly increased in patients receiving bivalirudin versus those receiving heparin (29.6 ± 20.7 vs 16.5 ± 13.6 hrs, p=0.045). Independent predictors of hemofilter survival were use of bivalirudin therapy and increased antithrombin III activity. No patients randomized to bivalirudin experienced any bleeding or thrombosis events; one patient who received heparin developed alveolar hemorrhage, and one developed a lower extremity deep vein thrombosis.. Compared with heparin, bivalirudin was more efficacious in prolonging hemofilter survival time and was well tolerated. Additional studies of bivalirudin for prevention of hemofilter occlusion during continuous renal replacement therapy are warranted.

Besides possible bleeding complications a further problem in anticoagulation during continuous renal replacement therapy (CRRT) is the development of heparin-induced thrombocytopenia type II (HIT II) where further anticoagulation with heparin is contraindicated. The application of continuous hirudin as alternative for heparin caused bleeding complications by comparable filter efficacy. Aim of this prospective-controlled pilot study was to compare the efficacy and safety of intermittent hirudin and continuous heparin for anticoagulation during CRRT in critically ill patients.. 26 patients receiving CRRT were randomly allocated to two groups: Heparin group (14 patients): continuous administration of 250 IU/h heparin, dose was adjusted in 125 IU/h steps with a targeted activated clotting time (ACT) of 180-210 s. Hirudin group (12 patients): initial bolus application of 2-2-5 microg/kg hirudin, dose was adjusted in 2 microg/kg bolus steps with a targeted ecarin clotting time (ECT) >80 s. Observation time was 96 hours.. Measured filter run time was virtually longer for heparin. No bleeding complications were observed in the hirudin group, two bleeding complications in the heparin group.. Intermittent hirudin can be used safely for anticoagulation in CRRT. However, the in tendency better filter survival for heparin elucidates the need for further investigations to find the right dosage equilibrium between filter clotting and bleeding complications.

To compare the efficacy and safety of hirudin and heparin for anticoagulation during continuous renal replacement therapy (CRRT) in critically ill patients.. Prospective, randomized controlled pilot study.. Single centre; interdisciplinary intensive care unit at a university hospital.. Seventeen patients receiving CRRT.. Patients were randomly allocated to two groups. Heparin group (nine patients): continuous administration of 250 IU/h heparin; dose was adjusted in 125 IU/h steps with a targeted activated clotting time (ACT) of 180-210 s. Hirudin group (eight patients): continuous infusion of 10 micrograms/kg/h hirudin, dose was adjusted in 2 micrograms/kg/h steps with a targeted ecarin clotting time (ECT) of 80-100 s. Observation time was 96 h.. Measured filter run patency and haemofiltration efficacy did not significantly differ between the two groups. Three bleeding complications were observed in the hirudin group, none in the heparin group (P < 0.01). At the onset of bleeding, which occurred 60 or more hours after the start of therapy, only one patient was still under continuous hirudin administration but levels were either in therapeutic range or below.. Hirudin can be used efficiently for anticoagulation in CRRT. Late bleeding complications may have been caused by possible hirudin accumulation, but this was not evident from hirudin plasma and ECT levels. Since bleeding complications were observed only in the presence of documented coagulation disorders, not only adequate drug monitoring but also the plasmatic and cellular coagulation status of the patient should be taken into consideration for adjusting hirudin dosage.

Recombinant hirudin (lepirudin) is a potent direct thrombin inhibitor, which has been approved for the treatment of heparin-induced thrombocytopenia type II (HIT). Because the drug is mainly eliminated by the kidneys, a single loading dose of hirudin may induce therapeutic anticoagulation for up to one week in patients with renal insufficiency. Thus, the use of hirudin in critically ill patients with renal failure could markedly increase their bleeding risk. In this study, hirudin was used in critically ill patients with suspected HIT while on continuous venovenous hemodialysis (CVVHD).. Hirudin anticoagulation was performed in seven critically ill patients with suspected HIT. Four patients were initially anuric. Three patients had residual renal function. In all 64 CVVHD treatments (mean duration 12 hr), a polysulfone high-flux hemodialyzer (0.75 m2) with a dialysate flow rate of 1.5 liter/hr and an ultrafiltration rate of up to 200 ml/hr was used. Hirudin was given either as continuous intravenous infusion or as repetitive intravenous boli. Monitoring of anticoagulation was performed by measurements of the systemic activated partial thromboplastin time (aPTT).. Hirudin dosage had to be individualized according to the risk of bleeding or clotting. During CVVHD, a continuous intravenous infusion (0.006 to 0.025 mg/kg body wt/hr, N = 2) or repetitive intravenous boli (0.007 to 0.04 mg/kg, N = 5) were given. Two patients required blood transfusions prior to and during hirudin treatment. In five patients without a high bleeding risk, the hirudin dose was adjusted to achieve the target aPTT (1.5 to 2.0 x baseline) in order to prevent thrombotic complications or frequent clotting in the extracorporal circuit. Hirudin dose requirements depended on residual renal function and extracorporal clearance.. We conclude from these first clinical data that anticoagulation with hirudin in critically ill patients on continuous hemodialysis can be performed without excessive bleeding risk by combining close clinical and laboratory monitoring. The hirudin dose has to be reduced because of renal failure, and may require adjustment for residual or recovering renal function and extracorporal elimination.

As patients transition between dialysis modalities, and from the intra- to the inter-dialytic period, medications with a narrow therapeutic index that are cleared in dialysis may require dose adjustments and close monitoring. Three cases of patients receiving bivalirudin while converting from continuous to prolonged intermittent renal replacement therapy are reported. Details provided include flow rates and ultrafiltrate volume. In these cases, it appears pre-emptive dose adjustments may be unwarranted, and clinicians should be aware of potential rebound after cessation of dialysis.

Patients with a previous history of heparin-induced thrombocytopenia are at a higher risk for thromboembolic events, and heparin administration is formally contraindicated. Bivalirudin has been reported as an alternative therapy whenever an intervention that requires systemic anticoagulation and cardiopulmonary by-pass pump is needed. We present the case of a patient diagnosed with heparin-induced thrombocytopenia and heparin-PF4 (+) antibodies requiring a triple cardiac valve replacement who developed fulminant coagulopathy after bivalirudin administration. A discussion on the serious difficulties that the management of these types of patients involves, as well as a review of prevention strategies are presented.

To describe a case of successful bivalirudin use as a prefilter anticoagulant in continuous venovenous hemofiltration (CVVH).. A 30-year-old male was brought to the hospital by ambulance with an anterior communicating artery subarachnoid hemorrhage, signs of intraparenchymal hemorrhage, and hydrocephalus. During the patient's complicated hospital course, he developed acute renal failure requiring CVVH, as well as hepatic insufficiency (Child-Pugh class B). Unfractionated heparin was used as a prefilter anticoagulant. After he had a positive heparin-induced thrombocytopenia (HIT) antibody test, prefilter heparin was discontinued in favor of bivalirudin. Filter survival and systemic activated partial thromboplastin time (aPTT) values were compared between prefilter heparin (n = 5) and bivalirudin (n = 4). Filter survival was similar (median 26 h with heparin vs 37 h with bivalirudin; p = 0.52). Prefilter bivalirudin 1-2.5 mg/hour (0.009-0.023 mg/kg/h) was effective in maintaining systemic aPTTs that were 1-1.4 times the reference range. Serotonin release assay and subsequent HIT antibodies were negative. The patient's renal function improved and CVVH was discontinued.. Critically ill patients requiring CVVH often need regional or systemic anticoagulation to prevent filter occlusion. In some patient populations, such as those with HIT or liver failure, prefilter heparin and regional citrate, respectively, may not be options. Alternative anticoagulants may be needed to avoid complications of frequent filter occlusions. The direct thrombin inhibitors (DTIs) lepirudin and argatroban have been used to maintain hemofilter patency, in small studies. Bivalirudin may have pharmacokinetic advantages over other DTIs when used in patients with hepatic and renal impairment. In our patient, bivalirudin provided a safe alternative to heparin therapy and was effective in maintaining hemofilter patency during CVVH.. Prefilter bivalirudin may be an option to prevent filter occlusion in patients requiring continuous renal replacement therapy. Future studies are needed to validate the safety and efficacy of bivalirudin as a prefilter anticoagulant.

The decision for an anticoagulant for renal replacement therapy (RRT) in patients with acute renal failure and heparin-induced thrombocytopenia (HIT) has to be made carefully. Based on results from the literature argatroban is favoured in patients without hepatic dysfunction, referring to its short halftime and easy feasable monitoring. In the case of coexsisting hepatic disorder, danaparoid provides a safe alternative therapy. However, long halftime and the difficult elimination of the substance are unfavourable. Lepirudin represents another possible anticoagulant therapy. Bleeding complications and monitoring of the ecarin clotting time imposes limitations. Experiences with bivalirudin, fondaparinux and prostaglandines are limited and future trials will have to determine the significance of their application in RRT in HIT patients. Furthermore it has to be proven whether the combination of alternative anticoagulants with citrate prolongates circuit halftime of CVVH.

A 56-year-old man with heparin-induced thrombocytopenia with thrombosis syndrome (HITTS) received anticoagulation with recombinant hirudin (lepirudin) for emergency coronary artery bypass graft (CABG) surgery and aortic valve replacement. The patient experienced life-threatening refractory bleeding that was successfully treated with recombinant factor VIIa. He had a history of infective endocarditis that resulted in severe aortic insufficiency, three-vessel coronary artery disease, and acute renal failure requiring hemodialysis. The patient was transferred from another hospital for the emergency surgery, but before his transfer, he developed HITTS secondary to therapeutic heparin for a deep vein thrombosis of the lower extremity. The presence of HITTS, the urgent nature of the case, and the availability of the direct thrombin inhibitor led the surgical team to select lepirudin for anticoagulation to facilitate cardiopulmonary bypass. After separation from cardiopulmonary bypass, the patient was in a coagulopathic state due to the inability to reverse the lepirudin and the slowed elimination of the drug secondary to inadequate renal function. As a result, the patient experienced excessive generalized oozing that was unresponsive to traditional therapies and blood product transfusions. Recombinant factor VIIa 35 microg/kg was given as rescue therapy. The bleeding slowed, which allowed placement of chest tubes and closing of the sternum. The patient was transferred to the intensive care unit in stable condition with no evidence of thrombosis in the freshly placed bypass grafts or on the bioprosthetic valve. Recombinant factor VIIa appears to be a suitable option as salvage therapy in patients with refractory bleeding secondary to anticoagulation with a direct thrombin inhibitor during cardiac surgery.

After a Caesarean section subcutaneous bleeding with a secondary infection occurred accompanied by acute renal failure. Additionally the diagnosis of a heparin-induced thrombocytopenia type II could be made. Therefore, haemodialysis treatments were performed with r-hirudin as an alternative anticoagulation. Even in dialysis dependent acute renal failure a safe anticoagulation with r-hirudin is possible if aPTT and plasma r-hirudin are closely monitored.

The endothelial vasoconstrictor endothelin (ET) can induce acute renal failure when fibrinolysis and vasodilatory prostanoids (PGs) are inhibited. This study compares therapeutic agents preventing ET-induced acute renal failure in anesthetized female pigs. We investigated the effect of four ET boli (1.5 microg/kg, i.v.) after pretreatment with indomethacin (2 mg/kg) and epsilon-aminocaproicacid (100 + 50 mg/kg) alone (controls, group 1) or during additional nifedipine (10 microg/kg/h; group 2), hirudin (0.5 mg/kg; group 3), or enalapril (2 x 0.15 mg; group 4) on coagulation, PGs, and renal function. The ET-induced blood pressure increase was lower in groups 2 to 4 (lowest in group 3, P < 0.05). PG synthesis was blocked in all groups. The initial hypercoagulability (controls) resulted in disseminated intravascular coagulation that was prevented by hirudin and was attenuated in groups 2 and 4. At the end of the experiment, creatinine clearance was significantly (P < 0.05) decreased. The recovery of renal function two hours after the last ET bolus was most pronounced in the hirudin group. All therapeutic drugs attenuated ET-induced impairment of renal function. Hirudin seems to be the most potent protective drug. Prevention of further ET release evoked by ET-mediated secretion of thrombin might explain this. These results suggest three important pathways for ET's hemodynamic and renal effects.
