Abstract:
Objective:To analyze the independent risk factors of ulcerative colitis (UC) with thromboembolism (TE), in order to diagnose UC with TE as early as possible and take corresponding preventive measures, so as to improve the prognosis and reduce the mortality of UC with TE.Methods:From January 1, 2011 to December 31, 2020, at the First Affiliated Hospital of Xinjiang Medical University, from January 1, 2015 to December 31, 2020, at the Second Affiliated Hospital of Xinjiang Medical University, from January 1, 2015 to December 31, 2020, at the Fifth Affiliated Hospital of Xinjiang Medical University, during hospitalization 46 patients diagnosed with UC with TE were enrolled. According to the ratio of 1∶2, at same period 92 simple UC patients were selected as control. The condition of embolization of UC patients with TE was analyzed. The clinical data(hypertension history, length of hospital stay, etc.), the degree of disease activity, laboratory test indicators (prothrombin time (PT), D-dimer, fibrin degradation product(FDP), hemoglobin(Hb), mean platelet volume(MPV), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), etc.)of the patients of UC with TE and UC without comorbidities were compared. Multivariate logistic regression was used to analyze the independent risk factors of UC with TE. Independent sample t test, Mann-Whitney U test, Chi-square test or Fisher′s exact probability method were used for statistical analysis. Results:Among the 46 cases of UC with TE, 14 cases (30.4%) had single site venous TE, mainly venous thrombosis of lower limbs; 20 cases (43.5%) had single site arterial TE, mainly myocardial infarction and cerebral infarction; 12 cases (26.1%) had multi-site TE. The proportion of patients with hypertension history and with severe active period of UC, and the levels of D-dimer, FDP, ESR and CRP in patients with UC with TE were all higher than those in patients without comorbidities(52.2%, 24/46 vs.33.7%, 31/92, 45.7%, 21/46 vs.19.6%, 18/92, (822.03±654.33) μg/L vs.(230.28±225.62) μg/L, 5.77 mg/L(6.87 mg/L) vs. 2.10 mg/L(1.55 mg/L), (46.32±28.27) mm/1 h vs.(33.08±24.30) mm/1 h, 22.05 mg/L(46.42 mg/L) vs. 5.58 mg/L(11.58 mg/L)); the hospital stay and PT were longer than those in patients without comorbidities ((12.76±10.18) d vs.(8.66±4.89) d, (14.13±6.06) s vs.(11.86±1.42) s); the Hb and MPV were lower than those in patients without comorbidities ((110.91±31.38) g/L vs.(123.83±27.67) g/L, (9.60±0.94) fL vs.(10.04±1.16) fL; and the differences were statistically significant( χ2=4.37 and 10.29, t=-5.96, Z=-5.78, t=-2.85, Z=-3.87, t=-2.58, -2.50, 2.47 and 2.47; all P<0.05). The results of multivariate logistic regression analysis showed that severe activity period of UC ( OR=3.079, 95% confidence interval (95% CI) 1.100 to 8.615), hypertension history ( OR=4.454, 95% CI 1.467 to 13.519), and D-dimer level( OR=1.003, 95% CI 1.001 to 1.005) were all independent risk factors of UC with TE(all P<0.05). Conclusions:Lower extremity venous, myocardial infarction and cerebral infarction are common in UC with TE. Severe activity period of UC, history of hypertension and D-dimer level are independent risk factors of UC with TE. These above factors should be paid attention to and corresponding prevention should be taken.
