Concomitant use of dupilumab with glucocorticoid in bullous pemphigoid reduces disease severity: A preliminary study.

OBJECTIVE: To retrospectively analyze the efficacy and safety of dupilumab in the treatment of bullous pemphigoid. METHODS: From October 2020 to October 2022, the medical records of patients with bullous pemphigoid who were treated with dupilumab in our department were collected retrospectively to analyze the therapeutic effect and changes in laboratory indexes. RESULTS: The records of a total of 11 patients with bullous pemphigoid who were treated with dupilumab was reviewed. Within 2 weeks of the treatment, 10 (90.9%) of the 11 patients had complete or substantial control of the disease. The BPDAI scores of the patients decreased from baseline 113 (62, 181) to 37 (6, 130) at 2 weeks (p = .001) and 4 (0, 37) at 12 weeks after treatment (p < .001). In the 11 patients treated with dupilumab, the relief time of pruritus was 0-3 days (0.5, 7) days, and the pruritus was significantly alleviated after 2 weeks (t = 15.925, p < .001). The DLQI score decreased from (25.5 ± 2.5) before treatment, to (11.8 ± 4.4) at 2 weeks (t = 10.764, p < .001) and (2.1 ± 1.9) at 12 weeks (t = 30.038, p < .001). The patients had high eosinophil counts, high serum IgE levels, low serum total protein levels, and abnormal blood coagulation function. The aforementioned indicators gradually returned to normal after treatment. No adverse reactions occurred during the treatment. CONCLUSION: Dupilumab can effectively control the condition of bullous pemphigoid, efficiently relieve pruritus symptoms, and is relatively safe.

Combined monitoring of thrombelastography, coagulation function and mean platelet volume/platelet count ratio to evaluate the prognosis of patients with sepsis / 中华急诊医学杂志

Objective:To compare the value of difference between thromboelastogram (TEG), coagulation function and mean platelet volume (MPV)/platelet count (PLT) ratio in sepsis patients with short-term prognosis.Methods:A total of 271 patients with sepsis admitted to the Affiliated Hospital of Xuzhou Medical University from January 2020 to September 2021 were retrospectively analyzed. The clinical data of the patients were recorded, and the SOFA score and APACHE Ⅱ score were calculated. The patients were followed up within 28 days and were divided into the survival group and death group. The TEG, coagulation function and MPV/PLT ratio were compared between the two groups. The independent prognostic factors of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were confirmed by Logistic regression analysis. The combination of Angle + CI + AT-Ⅲ + D-Di +MPV/PLT ratio was established, and the ROC curve was drawn to evaluate the prognostic value of Angle, CI, AT-Ⅲ and D-Di combined with MPV/PLT ratio in patients with sepsis.Results:The mortality rate of patients with sepsis was 42.4%. The D-Di and MPV/PLT ratio of the death group were significantly higher than those of the survival group, and the differences were statistically significant. Angle, CI and AT-III in the death group were significantly lower than those in the survival group, and the differences were statistically significant. Logistic regression analysis showed that Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were independent predictors of the prognosis of patients with sepsis (all P < 0.05) . The area under the curve of the combined detection of Angle, CI, AT-Ⅲ, D-DI and MPV/PLT ratio to evaluate the prognosis of sepsis at 28 days was 0.931, which was larger than that of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio alone (0.755, 0.790, 0.776, 0.729 and 0.746). The sensitivity and specificity of the combination of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were 83.5% and 91.0%, which were also higher than those of the single index . Conclusions:Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio are independent prognostic predictors of patients with sepsis. The combination of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio has high sensitivity and specificity in evaluating the prognosis of sepsis.

Effects of Astragalus Polysaccharides Nanoparticles on Cerebral Thrombosis in SD Rats.

OBJECTIVE: To investigate the efficacy and improvement of Astragalus polysaccharides (APS) and APS-nano on cerebral thrombosis in rats. METHODS: A total of 72 SD rats were randomly divided into NC group, Model group, APS-Nano group, and APS group. The cerebral thrombosis Model of SD rats was established by injecting compound thrombus inducer into the internal carotid artery. After 14 days of different intervention treatments, the TTC staining of brain tissue were performed, and A/left brain wet weight ratio, left brain/right brain wet weight ratio, blood rheology indexes, and coagulation function indexes of cerebral thrombosis were measured. ELISA was used to measure the contents of thromboxane 2 (TXB2), 6-keto-prostaglandin F1α (6-Keto-PGF1α), tissue factor (TF), neuron-specific enolase (NSE), S-100ß, catenin (CAT), superoxide dismutase (SOD), as well as malondialdehyde (MDA). The binding specificity between miR-885-3p and TF was verified by the double-luciferin reporting experiment, and western blot was used to measure the expression level of TF protein. RESULTS: Compared with the Model group, after treatment with APS-nano or APS, the ratio of left brain/right brain wet weight decreased significantly. Whole blood low shear viscosity (WBLSV), whole blood high shear viscosity (WBHSV), plasma viscosity (PV), and erythrocyte aggregation index (Arbc) was all reduced. In addition, prothrombin time (PT) and activated partial thromboplastin time (APTT) were increased, and fibrinogen (FIB) content was decreased. The expression of TXB2, 6-Keto-PGF1α, and TF showed a downward trend. Similarly, the expression of TF protein was decreased. Furthermore, the contents of NSE and S-100ß proteins were all decreased, whereas the contents of CAT and SOD were increased, and the contents of MDA was decreased. At the same dose, compared with APS treatment, APS-nano treatment had a significant inhibitory effect on cerebral thrombosis in rats. Finally, we found that TF is a target gene of miR-885-3p and specifically binds to miR-885-3p. CONCLUSION: APS has a significant inhibitory effect on the formation of cerebral thrombosis induced by compound thrombus inducers. Moreover, APS-nano has a more significant inhibitory effect on cerebral thrombosis. Meanwhile, the regulation of miR-885-3p regulating TF expression may be related to the occurrence of cerebral thrombosis.

The effect of remote ischemic conditioning on blood coagulation function and cerebral blood flow in patients with aneurysmal subarachnoid hemorrhage.

OBJECTIVE: To explore the effect of remote ischemic conditioning (RIC) on blood coagulation function and cerebral blood flow in patients with aneurysmal subarachnoid hemorrhage. PATIENTS AND METHODS: According to inclusion and exclusion standards, from October 2017 to June 2018, 30 consecutive patients of aneurysmal subarachnoid hemorrhage admitted to Intensive Care Unit, Department of Neurosurgery at Xuanwu Hospital, were given remote ischemic conditioning 5 times intervention to each patient within 7 days, and blood coagulation function testing, including prothrombin activity (PTA), prothrombin time (PT), activated partial prothrombin time (APTT), fibrinogen (Fib), D-dimer, and thromboelastogram (TEG, including R, K, Angle, MA, EPL, LY30, A, CI, G, and A30) were performed for each patient before and after the RIC intervention, as well as venous ultrasound monitoring before and after the RIC intervention for detection of deep vein thrombosis (DVT). Transcranial Doppler evaluation (TCD), including cerebral blood flow of bilateral ACA, MCA, PCA and intracranial segments of VA, as well as BA and the ratios of MCA cerebral blood flow/terminal segment of ipsilateral ICA cerebral blood flow, was performed before and after RIC intervention; and fresh infarction was evaluated by head CT or MRI recheck after RIC intervention. Thirty cases without RIC intervention of matched age, gender, and Hunt Hess grade with aneurysmal subarachnoid hemorrhage were selected to compare coagulation function and cerebral blood flow using TCD with RIC group. RESULTS: (1) Comparing the data before and after the RIC intervention, there was no significant difference for APTT, Fib, and D-dimer (P > 0.05), while PTA decreased and PT increased slightly after intervention as well as INR (P < 0.05) but all still in normal reference values. (2) Comparing the data before and after the RIC intervention, within TEG parameters, only the R value increased with significant difference (P < 0.05) but still in normal reference value, while K, Angle, MA, EPL, LY30, A, CI, G, and A30 had no significant difference (P > 0.05). (3) Comparing the data before and after the RIC intervention, DVT was not detected on the pressurized limbs of patients. (4) Comparing the data before and after the RIC intervention, the cerebral blood flow of bilateral MCA, L-ACA, L-VA, and BA increased (P < 0.05), while the elevation ranges were all in 25%, and the other parameters showed no significant difference. (5) Head CT or MRI showed no fresh cerebral infarction after the RIC intervention. (6) Compared with the group without RIC intervention, the coagulation function and the cerebral blood flow evaluated by TCD of the RIC group showed no statistical difference (P > 0.05) except APTT and D-dimer decreased after RIC but still in normal reference values. CONCLUSION: RIC showed no obvious effect on blood coagulation function and cerebral blood flow in patients with aneurysmal subarachnoid hemorrhage both after the intervention and compared with the non-intervention group. DVT was not detected on the pressurized limbs of patients and no fresh cerebral infarction was detected. This preliminary study confirmed the safety of RIC on blood coagulation function and cerebral blood flow in patients with aneurysmal subarachnoid hemorrhage, and the application of RIC on patients with aneurysmal subarachnoid hemorrhage needs further study to confirm and validate the safety and effectiveness.

Effect of vascular interventional therapy on coagulation function in patients with advanced tumors: A retrospective study / 中国肿瘤临床

Objective: To study the changes in coagulation function in patients with advanced tumors before and after vascular interventional therapy. Methods: A total of 174 patients with middle-late stage tumors undergoing oncology vascular interventional treatment at Beijing Hospital Of Traditional Chinese Medicine Affiliated With Capital Medical University, between January 2018 and October 2018 were included in this retrospective analysis. Changes in platelets (PLT) and related blood coagulation indicators were observed before and after vascular intervention. Among them, 63 patients who received relevant indicators detection within a week after vascular intervention were in group A, and 111 patients who received relevant indicators detection 1 month (30±7 days) after vascular intervention were in group B. SPSS version 22 software was used for statistical analysis. Results: In group A, fibrinogen (FIB) and D-dimer (D-D) values significantly increased, activated pattial thromboplastin timeAPITshortened, and PLT values decreased compared to those before treatment (all P0.05) than those before treatment. Before vascular interventional therapy, a total of 58 patients had hypercoagulability, including 28 patients in group A (48.3%) and 30 patients in group B (51.7%). In contrast, after vascular interventional therapy, a total of 71 (40.8%) patients had hypercoagulability, including 40 (56.3%) patients in group A and 31 (43.7%) patients in group B. Conclusions: Vascular interventional treatment can affect the related blood clotting index in the short term, which is intensified in patients with middle-late tumors and a high blood coagulation state. However, over time the coagulation state gradually mitigated and eventually returned to before-treatment levels. These findings suggest that patients' coagulation function should be closely monitored after intervention treatment.

Safety and efficacy of regional citrate anticoagulation in continuous blood purification treatment of patients with multiple organ dysfunction syndrome

The aim of this study was to discuss the safety and efficacy of regional citrate anticoagulation (RCA) on continuous blood purification (CBP) during the treatment of multiple organ dysfunction syndrome (MODS). Thirty-five patients with MODS were divided into two groups: the local citrate anticoagulation (RCA) group, and the heparin-free blood purification (hfBP) group. The MODS severity was assessed according to Marshall's MODS score criteria. Blood coagulation indicators, blood pressure, filter lifespan, filter replacement frequency, anticoagulation indicators, and main metabolic and electrolyte indicators were analyzed and compared between RCA and hfBP groups. RCA resulted in lower blood pressure than hfBP. The filter efficacy in RCA treatment was longer than in the hfBP group. The blood clearance of creatine, blood urea nitrogen and uric acid was better in the RCA group. RCA also led to higher pH than hfBP. Neither treatment resulted in severe bleeding events. In addition, MODS score was positively correlated with prothrombin time and activated partial thromboplastin time but negatively correlated with platelet concentration. RCA is a safer and more effective method in CBP treatment; however, it could also lead to low blood pressure and blood alkalosis.

The effects of platelet apheresis on blood saving and coagulation in bilateral total hip replacement: A prospective study on 60 patients.

BACKGROUND: Preoperative platelet rich plasma (PRP) harvest has been used in cardiopulmonary surgery for more than 10 years. There is no previous study dealing with PRP in bilateral total hip replacement. This study was to investigate the effects of PRP on blood saving and blood coagulation function in patients with bilateral total hip replacement. PATIENTS AND METHODS: A prospective, randomized, clinical trial was conducted. Sixty patients were enrolled, including 30 patients undergoing PRP in the PRP group and 30 controls. The surgery time, total transfusion volume, blood loss, allogenic blood transfusion, autologous blood transfusion, urine volume, drainage volume, some blood parameters (including Fibrinogen, D-dimer, Prothrombin time, international normalizedratio, activated partial thromboplastin time, Platelet, Haemoglobin B), thrombelastogram (TEG) and blood-gas parameters were studied in the perioperative stage. The measurement data were analyzed statistically. RESULTS: There was no statistical difference between the two groups in baseline characteristics, surgery time, total transfusion volume, blood loss, autologous blood transfusion, etc. Allogenic blood transfusion in the PRP group was less than the control group with statistical difference (p = 0.024). Fibrinogen in the PRP group was higher than the control group (p = 0.008). Among the TEG indicators, activated clotting time and coagulation time K in the PRP group were less than the control group. Clotting rate and maximum amplitude in the PRP group were higher. The blood-gas parameters presented no statistical difference. CONCLUSION: The results suggested that PRP probably played a positive role in blood coagulation function as well as blood saving in patients with bilateral total hip replacement.

Researches on inflammatory factor and blood coagulation in patients with laparoscopic gastric cancer radical surgery / 天津医药

Objective To investigate the change of inflammatory factor and blood coagulation in patients with laparo?scopic gastric cancer radical surgery. Methods Data of seventy-seven stomach cancer patients hospitalized in our hospital and received the surgical treatment from June 2012 to June 2014 were retrospectively analyzed. Thirty-eight of these pa?tients underwent laparoscopic treatment (laparoscopic group) and 39 cases received laparotomy treatment (laparotomy group). The values of interleukin-6 (IL-6), IL-8 and tumor necrosis factor alpha (TNF-α) were analyzed at the time points of preop?eration and 6 h, 24 h after the surgery in two groups. The levels of activated partial thromboplastin time (APTT), prothrombin time (PT), international standardization ration (INR), fibrinogen (FIB) and D dimer (D-D) were also analyzed at the same time points in two groups. The postoperative thrombosis and tumor recurrence rate were also analyzed in two groups of pa?tients. Results There were no significant differences in the gender, age, the size of tumor, differentiation degree and TNM staging between two groups of patients. The serum levels of IL-6, IL-8 and TNF-αwere significantly increased after surgery in two groups (P < 0.01), and which were significantly higher in laparotomy group than those of laparoscopic group (P<0.01). The levels of APTT, PT and INR were significantly lower after surgery in two groups of patients, and which were signifi?cantly lower in laparoscopic group than those of laparotomy group (P<0.05). The levels of FIB and D-D were significantly increased after operation in two groups of patients (P<0.05), which were significantly higher in laparoscopic group than those of laparotomy group (P<0.05). The postoperative recurrence of cancer was less in laparoscopic group than that of lapa?rotomy group. But, the postoperative thrombosis was more in laparoscopic group than that of laparotomy group. Conclusion There was less release of inflammatory mediators and less effect on the body’s immune function in patients with laparoscopic gastric cancer radical surgery. But, the surgery has a large influence in blood coagulation, we should pay attention to it in the clinical treatment.

Blood coagulation function changes and intervention effects of metformin in patients with impaired glucose tolerance / 中国医师进修杂志

Objective To investigate the blood coagulation function changes and intervention effects of metformin in patients with impaired glucose tolerance.Methods One hundred patients with impaired glucose tolerance and 50 healthy volunteers (control group) were recruited.The patients with impaired glucose tolerance were divided into test group 1 and test group 2 by random digits table method.The patients in test group 2 were given metformin and the patients in test group 1 were given the same dosage of placebo.The oral glucose tolerance test (OGTT),glycosylated hemoglobin (HbA1c),prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT) and fibrinogen (Fib) level were determined before and after treatment.Results Compared with those in control group,the patients in test group 1 and test group 2 had higher level of 2 h postprandial blood glucose (2 h PBG),HbA1c and Fib,and lower level of APTT,PT (P ＜ 0.05).The level of 2 h PBG,HbA1c and Fib in test group 2 were significantly lower than those in test group 1,(6.6 ± 2.5) mmol/L vs.(7.9 ± 3.6) mmol/L,(5.2 ± 1.3)％ vs.(5.8 ± 1.4)％,(3.0 ± 1.0) g/L vs.(3.6 ± 1.2) g/L,and the level of APTT and PT were significantly higher than those in test group 1,(34.3 ± 6.8) s vs.(31.6 ± 6.5) s,(12.6 ± 0.7) s vs.(12.3 ± 0.7) s,P ＜ 0.05.Compared with those in control group,there were no significant differences (P ＞ 0.05).Pearson line correlation analysis revealed that APTT and PT had negative correlation with 2 h PBG and HbA1c (P ＜ 0.01),and Fib had positive correlation with 2 h PBG and HbA1c (P ＜ 0.01).TT had no correlation with 2 h PBG and HbA1c (P ＞ 0.05).Conclusion Blood coagulation function of patients with impaired glucose tolerance may have some alteration,and appropriate therapeutic intervention can reduce the risk factors for cardiovascular disease.

Investigation on change regulation of blood coagulation function before and after treatment of snake bite patients / 国际检验医学杂志

Objective To explore the change regulation of blood coagulation function before and after treatment of snake bite pa‐tients .Methods A total of 226 hospitalized patients with clear diagnosis belong to what kind of snakes in the past two years were selected in this study ,39 cases were bit by coral ,76 cases were bit by trimeresurus stejnegeri ,47 cases were bit by cobra ,24 cases bit by king cobra ,40 cases were bit by adder .Five blood coagulation indexes were determined before and after treatment various pe‐riods for these patients .The tested results were made to statistical analysis according to kind of snakes ,periods and disease condi‐tion .Results D‐D level obvious .rise before treatment for the severe cases patients of coral snake bite (P0 .05) before and after treatment ,only D‐D level of the severe cases had statistical significance before treat‐ment in contrast to the mild cases of cobra bite (P< 0 .05) .The changes of 5 item blood coagulation indexes were all very large whether mild or severe for viper bite patients ,a number of comparisons had statistical significance difference (P<0 .05) whether before or after treatment and whether mild or severe for viper bite patients .Conclusion The bite of coral snake ,cobra and king co‐bra affect little for the blood coagulation function .The severe cases patients of trimeresurus stejnegeri bite might lead to more seri‐ous blood coagulation function abnormality but the recovery is faster after treatment .The viper bite might lead to maximum blood coagulation function abnormality and the recovery is slow after treatment .
