Increased thrombin-activatable fibrinolysis inhibitor levels in patients with chronic rhinosinusitis with nasal polyps. J Allergy Clin Immunol 2019; 144:1566-1574.e6.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a heterogeneous chronic inflammatory disease subdivided based on the presence or absence of nasal polyps (NPs). Histologic features of chronic rhinosinusitis with nasal polyps (CRSwNP) include inflammatory cell infiltration and excessive fibrin deposition in NPs. Thrombin-activatable fibrinolysis inhibitor (TAFI) is an enzyme that plays an antifibrinolytic role in the body. The significance of TAFI has been documented in patients with chronic inflammatory diseases, including chronic lung disease; however, it has not been evaluated in the pathogenesis of NPs. OBJECTIVE The objective of this study was to evaluate the potential role of TAFI in the pathogenesis of NPs. METHODS Nasal lavage fluid was collected from control subjects and patients with CRS. We measured levels of thrombin/anti-thrombin complex (TATc) and TAFI protein using an ELISA. RESULTS TATc levels in nasal lavage fluid were significantly increased in patients with CRSwNP and patients with chronic rhinosinusitis without nasal polyps (CRSsNP) compared with control subjects, and TAFI levels in nasal lavage fluid were also significantly increased in patients with CRSwNP compared with those in control subjects and patients with CRSsNP. There was a significant correlation between TATc and TAFI levels in nasal lavage fluid. Interestingly, patients with CRS and asthma showed increased TATc and TAFI levels in nasal lavage fluid compared with those in patients with CRS without asthma, especially patients with CRSwNP. CONCLUSIONS Increased TATc and TAFI levels in nasal passages of patients with CRSwNP might participate in fibrin deposition in NPs and might play a role in the pathogenesis of CRSwNP and asthma.

Abstract
AIM Coagulation disorders may develop in association with severe acute pancreatitis (AP). Plasma thrombin-antithrombin III complex (TAT) levels are one of the principal markers of coagulation disorder. The purpose of this study was to evaluate TAT and other hemostatic parameters in patients with AP and to examine whether or not these parameters indicate the severity of AP. METHOD Forty-six patients with AP (14 severe, 32 non-severe) and a 30-member healthy control group were recruited. The severity of AP was determined using the revised Atlanta classification. ELISA was used to measure patients' plasma TAT levels. RESULTS The TAT levels of AP patients at presentation were higher than those of the control group (p = 0.005). The plasma TAT levels of patients with severe AP were also significantly higher than those of patients with non-severe AP (p = 0.05) and of the control group (p < 0.001). The general accuracy, sensitivity and specificity of TAT levels in predicting the severity of AP were 77.4, 77.8, and 77.3% respectively. CONCLUSION The coagulation cascade was activated in the AP patients in our study, and this was shown to become more pronounced as severity of the disease increased. Plasma TAT levels at the time of presentation in patients with AP can be used as a marker for predicting the severity of the disease.

Abstract
Recurrent spontaneous abortion (RSA) is defined as 3 or more consecutive pregnancy failures. Thrombin-activatable fibrinolysis inhibitor (TAFI) is a plasma zymogen that regulates both fibrinolysis and inflammation. The TAFI 1040C/T polymorphism could alter the circulating levels of TAFI with a reduced capacity to remove the fibrin clots from the circulation; therefore, it could be considered a molecular risk factor for RSA. The TAFI 1040C/T polymorphism was studied in 50 patients with RSA by polymerase chain reaction-restriction fragment length polymorphism technique and compared to 50 age- and gender-matched healthy volunteers as a control group to verify its possible association with RSA. In case group, the wild genotype (C/C) and heterozygous genotype (C/T) did not reduce the risk of RSA (odds ratio: 0.368 and 0.767, respectively), even when compared to the number of RSA ( P = .71). A higher frequency of C allele in the control group and a higher frequency of T allele in the case group were observed but with no statistical significance. In conclusion, our study revealed that TAFI 1040C/T could not be considered a molecular predictive factor for RSA in Egyptians.
