Abstract Objectives The evidence supporting the role of circulating markers of inflammation in the pathogenesis of atria fibrillation remains controversial. This study investigated the levels of serum lipids, C-reactive proteins, erythrocyte sedimentation rate, prothrombin time, and platelet count in subjects with new-onset atria fibrillation (NAF), but with no established cardiac disease, in a Nigerian community. Methods The case control study involved a total of 200 subjects: 110 subjects with NAF and 90 apparently healthy subjects without AF, as control. AF was confirmed by a 12-lead electrocardiogram (ECG), while excluding subjects with high risk. Blood samples from the subjects were analyzed for the following parameters: C-reactive proteins using ELISA method and serum lipids using an enzymatic, colorimetric method; erythrocyte sedimentation rate, by Westergreen method; platelet count using a Midray hematology auto analyzer; and the prothrombin time using a tissue thromboplastin method. Data collected from the result were analyzed using SPSS version 15. Results There was a significant increase in the levels of C-reactive proteins and ESR in subjects with NAF when compared with the control subjects. A significant increase was observed in the mean values of total cholesterol and low-density lipoproteins in subjects with NAF, while that of high-density lipoproteins was lower in NAF than in controls. There was no significant difference in the mean values of triglyceride in NAF and the control. Results also showed significantly reduced prothrombin time, with more platelet count in subjects with NAF. The result demonstrated that females (56.3%) had greater risk of developing AF than males (45.8%), while incidence of AF was observed to increase with age. Conclusion The results of the markers assayed suggest marked dyslipidemia, inflammation, and thrombogenesis in subjects with new-onset AF. Hence dyslipidemia and inflammation play critical roles in the pathogenesis of atria fibrillation.

Введение. Метод Борна стал золотым стандартом тромбоцитарной агрегометрии вполне заслуженно: он исторически был разработан первым, первым же вошел в клиническую практику и за счет этого приобрел самую обширную доказательную базу. Имеющиеся сведения наглядно демонстрируют его достоинства и недостатки. Метод Platelet Function Analysis (PFA) был разработан значительно позднее, но во многом в ответ на ограничения метода Борна и в соответствии с клиническим требованием иметь в практике pointofcare метод оценки агрегационной активности тромбоцитов. Особенностью PFA является оценка агрегационного ответа тромбоцитов текущей (это важно) цельной крови в условиях имитации повреждения сосудистой стенки мелких сосудов. Цель исследования: изучить соответствие результатов теста PFA данным, получаемым с помощью золотого стандарта агрегатометрии по Борну, а также определить причины и диагностическое значение расхождений. Материалы и методы. Обследован 51 пациент (28 мужчин и 23 женщины) с хронической цереброваскулярной патологией. Из них 35 человек получали per os препараты ацетилсалициловой кислоты (АСК) в дозе 100 150 мг/сут (группа 1), а 16 пациентов клопидогрел в дозе 75 мг/сут (группа 2). Кроме того, 20 человек, получавших АСК, были обследованы дважды: до начала приема и через 14 дней. Все пациенты были обследованы по следующим показателям: концентрация гемоглобина, количество тромбоцитов, скорость оседания эритроцитов (СОЭ), содержание общего белка, глюкозы, триглицеридов и общего холестерина. Также определяли коагулологические показатели: активированное частичное тромбопластиновое время, протромбиновое время с расчетом международного нормализованного отношения, уровень фибриногена и концентрацию Ддимера методом латексных частиц с высоко специфичными моноклональными антителами к Ддимеру на автоматическом коагулометре ACL ElitePro (США) с использованием наборов реагентов фирмы Instrumentation Laboratory (США). Результаты. Группы оказались практически одинаковыми по возрасту, наличию и выраженности фонового воспалительного процесса и состоянию системы гемостаза. Оценка агрегации тромбоцитов в ответ на АДФ и адреналин у пациентов до начала приема АСК в дозе 150 мг/сут и через 2 нед не выявила противоречивых данных и показала, что оба метода отчетливо регистрируют ее угнетение. На фоне приема АСК результаты агрегометрии тромбоцитов обоими методами с индуктором АДФ совпали с коэффициентом корреляции r 0,74 (p 0,05), с индуктором адреналин с коэффициентом r 0,63 (p 0,05). На фоне приема клопидогрела результаты АДФиндуцированной агрегометрии, полученные обоими метода ми, совпадали с большим коэффициентом корреляции: r 0,82 (p 0,05), адреналининдуцированной агрегации r 0,88 (p 0,05). Корреляционный анализ выявил зависимость результатов, получаемых каждым методом на фоне приема АСК или клопидогрела, от следующих параметров: возраст, концентрация фибриногена, количество тромбоцитов и СОЭ, что в большей степени проявилось для PFA. Заключение. Очевидно, что метод Борна показывает лишь то, насколько тромбоциты в целом чувствительны к действию ингибитора агрегации, тогда как метод PFA демонстрирует реальную картину образования сгустка на фоне всех имеющихся условий, т.е. как результат всего многообразия взаимодействий тромбоцитов per se в цельной крови. Другими словами, метод PFA отражает общий уровень тромбогенности, которая, в свою очередь, очевидно является причиной так называемой резистентности к антиагрегантам, нередко наблюдаемой у данной категории больных. Introduction. Borns method became the gold standard of platelet aggregometry because it has been developed historically the first. On today it has the most extensive evidence base showing clearly its advantages and disadvantages. The Platelet Function Analysis (PFA) is a method developed much later as a response to the limitations of the Borns method in order to have a pointofcare platelet aggregometry in practice. The main feature of PFA is the evaluation of platelet aggregation occurring in flowing whole blood under conditions simulating vascular wall damage. Aim: to study the compliance between PFA test results and the data obtained by Borns aggregatometry as well as to determine the causes and diagnostic value of their discrepancies. Materials and methods. The study included 51 patients (28 men and 23 women) with chronic cerebrovascular pathology, from them 35 were intaking acetylsalicylic acid, ASA (100 150 mg/day per os, group 1), and clopidogrel in 16 patients (75 mg/day per os, group 2). In addition, 20 patients with ASA were examined twice as before as well as in 14 days. Lab testing included hemoglobin, platelet count, erythrocyte sedimentation rate, total protein, glucose, triglyceride, total cholesterol, activated partial thromboplastin time, prothrombin time as international normalized ratio, fibrinogen and Ddimer with using of ACL ElitePro coagulometer and reagents kits by Instrumentation Laboratory (USA). Results. The groups were appeared almost identical in age, the severity of the background inflammatory and the clotting conditions. Both methods have registered clearly platelet aggregation inhibition in 2 weeks of ASA administration both in response to ADP and to epinephrine, and no any disagreements was found between the methods. By ASA administration the ADPinduced aggregations from Borns method and PFA showed the correlation r 0.74 (p 0.05), the epinephrininduced aggregations have coincided with r 0.63 (p 0.05). In cases with clopidogrel we found large correlation coefficients as r 0.82 (p 0.05) and r 0.88 (p 0.05) between ADPinduced aggregations and between epinephrininduced aggregations, respectively. The correlation analysis revealed that the results obtained by each method were closely related to parameters such as age, fibrinogen, platelet count and erythrocyte sedimentation rate, and that was more evident for PFA. Conclusion. Obviously, the Borns method shows only how platelets are sensitive generally to the antiaggregation agents, whereas the PFA method plots a real picture of clot formation against all available conditions, i.e. as a result of the whole variety of platelet interactions per se in whole flowing blood. It does mean the PFA method reflects the overall level of thrombogenicity. In turn that is obviously the cause of the socalled resistance to antiplatelets observed often in such category of patients.

Currently, the epidemic situation regarding the incidence of coronavirus infection COVID−19 in Ukraine continues to be tense. In order to in−depth study of the problem of clinical features, treatment and prevention of this disease, as well as the development of a mathematical model for predicting the severity of its course, 30 patients aged 18 to 85 years were examined. Among the patients there were young and middle−aged people as well as elderly patients with chronic diseases, namely obesity, hypertension, diabetes. The diagnosis of coronavirus infection was confirmed in all the patients by molecular genetic method, i.e. SARS−CoV−2 RNA was isolated, and in 10 patients − IgM + IgG to SARS was determined by immunochromatographic analysis. With COVID−19, young and middle−aged patients have a fairly mild course with a decrease in platelet count by 7 %, erythrocyte sedimentation rate by 48 %, prothrombin by 14 % and D−dimer by 31 %. The construction of regression equations based on trend lines revealed that in elderly patients after treatment there was a further decrease in the level of D−dimer (20 %), an increase in platelet count (30 %), a decrease in white blood cell count (26 %), neutrophils (38 %), increase in lymphocyte levels by 3 times, decrease in erythrocyte sedimentation rate (by 10 %) and prothrombin parameters (by 15 %). Based on cluster and regression analysis, coefficients were calculated for each prognostic function. It was found that the linear dependence and statistically significant effect on the course of COVID−19 in all patients have leukocytes, erythrocyte sedimentation rate and D−dimer. In order to prevent the spread of coronavirus infection in Ukraine COVID−19 in this March, quarantine was introduced throughout the country, which is being extended to this day. There is no doubt about the importance of recommendations for improving anti−epidemic measures to prevent coronavirus infection throughout Ukraine. Key words: coronavirus infection, COVID−19, clinical blood counts, disease prognosis, anti−epidemic measures in Ukraine.

An estimated 50,000 Nigerian women die each year from complications of pregnancy and childbirth, accounting for 10% of global estimates of pregnancy maternal death with about 2% resulting from drug induction. This cross-sectional study sets out to evaluate the Prothrombin time test (PT), activated partial thromboplastin time test (aPTT) Erythrocyte sedimentation rate (ESR), and Platelet count (PC) of pregnant women attending antenatal clinics at Oredo Health Centre in Benin City, Edo State. A total number of 130 subjects comprising 100 pregnant women and 30 non-pregnant women were recruited for the study. Prothrombin time (PT), Activated Partial Thromboplastin Time (APTT), Platelet count and Erythrocyte Sedimentation Rate (ESR) were studied using standard manual methods. The prothrombin time (sec) of the pregnant women 1st trimester (19.12±0.77b), 2nd trimester (19.90±1.02 b) and 3rd trimester (19.66±0.56 b), activated partial thromboplastin time (sec) 1st trimester (44.02±1.17 b), 2nd trimester (47.72±1.47 b) and 3rd trimester (45.88±1.10b), Erythrocyte sedimentation rate (mm/hr) 1st trimester (24.37±3.04 a), 2nd trimester (37.83±4.53 a) and 3rd trimester (43.25±5.24 a) and platelet count (X109/L) 1st trimester (248.29±23.18a), 2nd trimester (236.33±13.84 b) and 3rd trimester (239.10±16.07 a) were significantly higher than the prothrombin time (sec) 16.48±0.81 a, activated partial thromboplastin time (sec) 36.53±1.42 a, ESR (mm/hr) 29.83±4.14 a and platelet count (X109/L) 201±9.54 an of the non-pregnant women (p<0.05). The ESR (mm/hr) of the 3rd trimester (43.25±5.24) was observed to be significantly higher than that of the 1st trimester (24.37±3.04) and 2nd trimester (37.83±4.53) (p<0.05). Our investigation showed that antibiotics in pregnancy have a deleterious effect on PT, ESR, APTT and PC studied. We recommend that pregnant women should be given due attention throughout the course and events of pregnancy to prevent or reduce the risk of thrombotic episodes and possible disseminated intravascular coagulation (DIC) with resultant better maternity/child safety and health outcome and educated on the effects of antibiotics to pregnancy.

Objective: To characterize viscoelastic testing profiles of children with multisystem inflammatory syndrome in children (MIS-C). Methods: This single-center retrospective review included 30 patients diagnosed with MIS-C from January 1 to September 1, 2020. Thromboelastography (TEG) with platelet mapping was performed in 19 (63%) patients and compared to age- and gender- matched controls via Student’s t-test and Wilcoxon rank sum test. Pearson’s and Spearman correlation were used to assess relationships between TEG parameters and inflammatory markers. Results: Patients with MIS-C had abnormal TEG results compared to controls, including decreased K time (1.1 vs. 1.7 min, P<0.01), increased alpha angle (75.0 vs. 65.7 degrees, P<0.01), increased maximum amplitude (70.8 vs. 58.3 mm, P<0.01), and decreased Ly-30 (1.1 vs. 3.7%, P=0.03); consistent with increased clot formation rate and strength, and slower fibrinolysis. TEG maximum amplitude was moderately correlated with erythrocyte sedimentation rate (r=0.60, P=0.02), initial platelet count (r=0.67, P<0.01), and peak platelet count (r=0.51, P=0.03). TEG alpha angle was moderately correlated with peak platelet count (r=0.54, P=0.02). 17 (57%) patients received aspirin (ASA) and anticoagulation, 5 (17%) received only ASA, and 3 (10%) received only anticoagulation. No patients had a thrombotic event. 6 (20%) patients had a bleeding event, none of which was major. Conclusions: Patients with MIS-C had evidence of hypercoagulability on TEG. Increased erythrocyte sedimentation rate and platelets were associated with higher clot strength. Treatment with ASA or anticoagulation was well tolerated. Further multi-center study is required to characterize the rate of thrombosis and optimal thromboprophylaxis algorithm in this patient population.
