Введение. Ревматические заболевания относятся к процессам, характеризующимся иммунным поражением различных органов и систем с выраженными изменениями сосудистой стенки и системы гемостаза. Цель исследования: изучить влияние высоких доз глюкокортикостероидов (ГКС) и цитостатиков на клинико-гемостазиологические показатели у больных системной красной волчанкой (СКВ). Материалы и методы. Обследовано 18 больных СКВ женщин (средний возраст — 35,6 ± 1,6 года), которые получали пульс-терапию ГКС и цитостатиком циклофосфаном по стандартной схеме. Критерии отбора для проведения пульс-терапии: высокая активность аутоиммунного процесса по шкалам SLAM, SLEDAI, ECLAM, поражение почек и центральной нервной системы. Гемостазиологические показатели исследовали до лечения, на 1-й и 14-й день после пульс-терапии. Для оценки состояния коагуляционного звена гемостаза определяли: активированное частичное тромбопластиновое время, тромбиновое время, протромбиновое время по Квику, содержание фибриногена, растворимых фибрин-мономерных комплексов, Д-димера, активность антитромбина III (АТ-III), протеина С, фибринолитической системы крови. Результаты. У больных СКВ наблюдали активацию коагуляционного гемостаза на фоне снижения активности естественных антикоагулянтов и процессов фибринолиза. На 1-е сутки после пульс-терапии выявлен значительный рост тромбинемии; к 14-у дню большинство показателей плазменного гемостаза возвращались к исходным на фоне снижения активности системы протеина С и роста активности АТ-III. Заключение. Исследование коагулологических параметров следует проводить всем больным СКВ, получающим пульс-терапию, так как существует угроза развития тромбозов у данных пациентов. Полученные данные подтверждают необходимость применения антикоагулянтов при назначении высоких доз ГКС и цитостатиков. Introduction. Rheumatic diseases are characterized by the immune damage of various organs and systems with expressed changes in the vascular wall and hemostasis. Aim: to study the eff ect of high doses of glucocorticosteroids (GCS) and cytostatics on the clinical and hemostasiological parameters in patients with systemic lupus erythematosus (SLE). Materials and methods. We examined 18 women with SLE of (average age — 35.6 ± 1.6 years) who received pulse therapy by GCS and cyclophosphamide according to the standard scheme. Selection criteria for pulse therapy were high activity of the autoimmune process according to SLAM, SLEDAI, ECLAM scales, kidney and central nervous system damage. Hemostasiological parameters were investigated before treatment, on the 1st and 14th days after pulse therapy. To assess the state of coagulation hemostasis, we determined: activated partial thromboplastin time, thrombin time, Quick prothrombin time, fibrinogen content, soluble fi brin-monomer complexes, D-dimer, activity of antithrombin III (AT-III), protein C, fibrinolytic system. Results. In patients with SLE, activation of coagulation hemostasis was observed with the reduction in the activity of natural anticoagulants and fi brinolysis processes. On the 1st day after pulse therapy, a signifi cant thrombinemia growth was detected; by the 14th day, most of plasma hemostatic parameters returned to baseline with reduction of protein C system activity and increasing of AT-III activity. Conclusion. The study of coagulological parameters should be carried out in all patients with SLE who receive pulse therapy, since there is a risk of thrombosis in these patients. The obtained data confirm the need for anticoagulants use in the appointment of high doses of GCS and cytostatics.

The authors report a case of a 19-year-old woman admitted for the investigation of fever and hemolytic anemia for the previous 2 months. As an inpatient, she had convulsions and sudden loss of consciousness, developing hemoptysis, hypoxia, and respiratory insufficiency. Examination showed pericardial effusions on the echocardiogram and bilateral alveolar condensations on the thoracic radiograph. A hypothetical diagnosis of systemic lupus erythematosus was made, and measurement of the antinuclear factor was requested along with daily pulse therapy methylprednisolone, in spite of which the outcome was fatal. Afterwards, the result of the antinuclear factor test was positive, with a titer of 1:5120, showing a fine punctiform pattern, fulfilling the criteria for systemic lupus erythematosus according to the American College of Rheumatology. Secondary pulmonary hemorrhage in this connective tissue disease is an uncommon but serious complication that involves a high level of mortality in spite of intensive treatment, as is also reported in the literature.

Abstract Acquired activated protein C resistance (APCR) has been hypothesized as a possible mechanism by which antiphospholipid antibodies (APLAs) cause thrombotic events (TEs). However, available evidence for an association of acquired APCR with APLAs is limited. More importantly, an association of acquired APCR with TEs has not been demonstrated. The objective of the study was to determine, in pediatric patients with systemic lupus erythematosus (SLE), whether (1) acquired APCR is associated with the presence of APLAs, (2) APCR is associated with TEs, and (3) there is an interaction between APCR and APLAs in association with TEs. A cross-sectional cohort study of 59 consecutive, nonselected children with SLE was conducted. Primary clinical outcomes were symptomatic TEs, confirmed by objective radiographic tests. Laboratory testing included lupus anticoagulants (LAs), anticardiolipin antibodies (ACLAs), APC ratio, protein S, protein C, and factor V Leiden. The results revealed that TEs occurred in 10 (17%) of 59 patients. Acquired APCR was present in 18 (31%) of 58 patients. Acquired APCR was significantly associated with the presence of LAs but not ACLAs. Acquired APCR was also significantly associated with TEs. There was significant interaction between APCR and LAs in the association with TEs. Presence of both APCR and LAs was associated with the highest risk of a TE. Protein S and protein C concentrations were not associated with the presence of APLAs, APCR, or TEs. Presence of acquired APCR is a marker identifying LA-positive patients at high risk of TEs. Acquired APCR may reflect interference of LAs with the protein C pathway that may represent a mechanism of LA-associated TEs.
