INTRODUCTION. Gastrointestinal bleeding is the most important complication associated with acetylsalicylic acid therapy. Patients with preexisting haemostatic disorders are at the higher risk and may experience life-threatening hemorrhagic syndrome. Platelet transfusions and desmopressin administration commonly successfully arrest bleeding. However, in clinical situations with profound bleeding and haemorrhagic shock, these therapeutic approaches may fail. CASE OUTLINE. We report a 24-year old female patient with previously undetected acquired platelet dysfunction, who underwent reconstructive surgical intervention. On the 20th postoperative day, acetylsalicylic acid was introduced due to reactive thrombocytosis (platelet count 1480x109/L) with daily dose of 100 mg tablets. On the 12th day of the acetylsalicylic acid treatment, massive gastrointestinal bleeding with haemorrhagic shock suddenly occurred. Attempts to control massive haemorrhage by resuscitation, blood products and haemostatics (desmopressin, tranexamic acid) failed. Two bolus doses of recombinant activated factor VII (rFVIIa) (100 ?g/kg and 60 ?g/kg respectively) in 90 minutes interval were given. Bleeding was successfully controlled with no requirements for further haemoproducts and haemostatic remedies treatment. CONCLUSION. This case demonstrates that the use of rFVIIa may be a specific treatment option in patients suffering from severe gastrointestinal bleeding associated with acetylsalicylic acid treatment.

Intermittent and concomitant acetylsalicylic acid (ASA) therapy was superimposed onto a 21-day regimen with diflunisal 250 mg b.i.d. Low doses of ASA (600 mg single dose or 300 mg q.i.d.) did not influence significantly diflunisal blood levels whereas a 600 mg q.i.d. dosing caused a small significant drop, especially at trough level. This drop is not expected to be clinically significant. No ototoxicity could be demonstrated with any treatment of diflunisal though four of fourteen subjects reported mild tinnitus during concomitant therapy at the higher doses of ASA. Diflunisal at 375 mg b.i.d. failed to alter the metabolism of a single dose of labelled ASA (600 mg) as judged by plasma levels, urinary excretion and plasma binding. Daily urinary excretion of prostaglandins E1 and E2 major metabolite was decreased by about 70% by diflunisal.

In a review, we described risks and benefits of surgery performed while continuing aspirin therapy in perioperative period. Aspirin therapy is associated with mild increase in surgery related bleeding risk. On the other hand, aspirin therapy leads to significant decrease of mortality and perioperative cardiovascular risk in most cases.

Введение. При использовании ацетилсалициловой кислоты (АСК) в качестве антиагреганта после операции аортокоронарного шунтирования (АКШ) может встречаться феномен резистентности к АСК, генез которого недостаточно изучен. С помощью хемилюминесцентного (ХЛ) анализа изучена функциональная активность тромбоцитов резистентных и чувствительных к АСК. Методика. Обследовано 104 пациента с хронической коронарной болезнью (ХКБ). Контрольная группа - 30 здоровых доноров. Забор крови проводили до АКШ, в 1-е и на 8-е - 10 сут после АКШ. Определяли агрегацию с коллагеном, адреналином, АДФ и резистентность тромбоцитов к АСК с помощью оптической агрегометрии с арахидоновой кислотой при уровне ≥20%. Исследовали спонтанную и АДФ-индуцированную ХЛ тромбоцитов с люминолом и люцигенином на биохемилюминесцентном анализаторе. Результаты. 71 пациент с ХКБ оказался чувствительным к АСК (чАСК), 33 - резистентными (рАСК). У чАСК пациентов большинство показателей ХЛ было выше, чем в контрольной группе в течение всего периода наблюдения, у рАСК пациентов таковые были на уровне контрольных значений. До АКШ у чАСК пациентов значения показателей ХЛ с люцигенином выше, чем у рАСК. В группе чАСК пациентов на 1-е сут после АКШ наблюдалось снижение ХЛ с люцигенином, а на 8-10-е сут повышение ХЛ с люминолом по сравнению с уровнем до операции. У рАСК пациентов наблюдается положительная корреляция показателей ХЛ и агрегации тромбоцитов. Заключение. С помощью ХЛ можно судить о функциональной активности тромбоцитов при ХКБ. Исследование показателей ХЛ позволяет до операции АКШ выявить рАСК пациентов. Наличие динамики в показателях ХЛ тромбоцитов у чАСК пациентов до и после АКШ, отсутствие таковой у рАСК пациентов позволяет сделать предположения о зависимости резистентности к АСК не только от внутреннего состояния тромбоцитов, но и от межклеточных связей. Introduction. Some patients after coronary artery bypass grafting (CABG) may be resistant to acetylsalicylic acid (ASA) used as an antiplatelet agent. The mechanisms of this condition are still under discussion. We studied the functional activity of ASA-resistant and -sensitive platelets using a chemiluminescent (CL) analysis. Methods. 104 patients with chronic coronary disease (CCD) were evaluated. The control group consisted of 30 healthy donors. Blood sampling was performed prior to CABG and at one and 8-10 days after CABG. Platelet aggregation with collagen, adrenaline, and ADP and platelet resistance to ASA were determined by optical aggregometry with arachidonic acid at a level ≥20%. Spontaneous and ADP-induced CL of platelets with luminol and lucigenin was studied with a biochemiluminescence analyzer. Results. 71 patients with CCD were found to be sensitive to ASA (sASA) whereas 33 patients were resistant to ASA (rASA). Most of CL indexes were higher in sASA patients than in the control group during the entire observation period; in rASA patients, values of these indexes were at the control level. Pre-CABG values of CL indexes were higher in rASA patients than in sASA patients. Lucigenin-enhanced CL was decreased in rASA patients on the first day after CABG and increased on days 8-10 compared to the preoperative level. CL indexes positively correlated with platelet aggregation in rASA patients. Conclusion. The CL method allows assessing the functional activity of platelets in CCD. The study of CL indexes may identify rASC patients before the CABG surgery. The dynamics of CL index values in sASK patients before and after surgery and the absence of such dynamics in patients with rASC suggests that aspirin resistance depends not only on the internal condition of platelets but also on intercellular relations.
