ABSTRACT

Objective:To analyze the clinical features of MDA5 antibody positive dermatomyositis (MDA5-DM) and to provide evidence for early diagnosis and treatment.Methods:From March 2019 to June 2021, 272 patients with anti-MDA5-DM from the Nanjing Medical University myositis-associated interstitial lung disease cohort were enrolled, with 76 patients with anti-synthetase syndrome (ASS) as the control group. The clinical characteristics and the occurrence of interstitial lung disease were analyzed. T-test was used for normally distributed and variance-homogeneous independent samples, Mann-Whitney U test for non-normally distributed data, and chi-square test or Fisher′s exact test for dichotomous variables. Results:Among the 272 anti-MDA5-DM patients, 88.6% (241/272) developed interstitial lung disease (ILD), and 33.8% (92/272) developed rapidly progressive ILD (RP-ILD). The six-month all-cause mortality rate of anti-MDA5-DM patients was 16.9% (46/272), and it was as high as 47.8% (44/92) for those with RP-ILD. Compared with ASS patients, anti-MDA5-DM patients had a significantly higher proportion of males, arthritis, Gottron's sign, heliotrope rash, V-sign, periungual erythema, and skin ulcers ( P<0.05). The levels of ALT, AST, and ferritin were significantly increased ( P<0.05). Compared with non-RP-ILD patients, RP-ILD patients had a significantly higher proportion of males [35.9%(33/92) vs. 23.3%(42/180), χ2=4.79, P=0.029], higher levels of LDH [387 (276, 547) U/L vs. 310 (245, 400) U/L, Z=-3.67, P<0.001], ESR [45.5 (29.25, 63.25) mm/1 h vs. 31.2 (20, 51) mm/1 h, Z=-3.71, P<0.001], CRP [10.9 (4.1, 25.2) mg/L vs. 4.54 (2.58, 9.08) mg/L, Z=-4.97, P<0.001], ferritin [1 340 (650, 2 000) ng/ml vs. 556 (203, 1 186) ng/ml, Z=-4.40, P<0.001], and a higher proportion of anti-Ro52 antibody and anti-MDA5 antibody co-positivity [87.0%(80/92) vs. 52.2%(94/180), χ2=31.87, P<0.001]. Conclusion:Anti-MDA5-DM patients are prone to develop RP-ILD and have poor prognosis.

ABSTRACT

Objective@#To evaluate the relationship between the status of collateral circulation provided by multiphase CT angiography and the benefit and risk of vascular recanalization in patients with middle cerebral artery (MCA) occlusion.@*Methods@#This retrospective study included 49 patients diagnosed with acute MCA occlusion and treated with rt-PA in the First Affiliated Hospital of Nanjing Medical University from October 2017 to September 2018. According to the ASPECTS collateral circulation score, the patients were divided into two groups: good collateral group (n=31) and poor collateral group (n=18). The benefits and risks after thrombolysis in the two groups were compared, including 24-h NIHSS score, 30-day mortality, 90-day modified rankin scale (mRS) score, and the incidence of symptomatic cerebral hemorrhage. Statistical analysis was performed using t test, corrected χ2 test, or Fisher's exact test.@*Results@#The 24-h NIHSS score and 90-day mRS score in the good collateral group were significantly lower than those in the poor collateral group (4.6±5.6 vs 12.5±8.4, P=0.00; 1.7±1.7 vs 3.1±1.5, P<0.05). The incidence of NIHSS score improved by ≥50% and the incidence of 90-day mRS 0-2 was significantly higher in the good collateral group after 24 h of thrombolysis (77.4% vs 27.8%, P<0.05; 80.6% vs 27.8%, P=0.00); The incidence of symptomatic cerebral hemorrhage was significantly lower in the good collateral group than in the poor group (9.7% vs 50.0%, P<0.05). There was no significant difference in mortality between the two groups after 30 days of thrombolysis (P>0.05), but the 30-day mortality of the poor collateral group was still greater than that of the good collateral group (11.1% vs 0%).@*Conclusion@#For patients with acute MCA infarction and receiving vascular recanalization therapy, patients with good collateral circulation can achieve good clinical outcomes, restore better recent neurological function, and obtain lower incidence of symptomatic cerebral hemorrhage and lower disability and mortality rate.

ABSTRACT

Objective To evaluate the relationship between the status of collateral circulation provided by multiphase CT angiography and the benefit and risk of vascular recanalization in patients with middle cerebral artery(MCA)occlusion.Methods This retrospective study included 49 patients diagnosed with acute MCA occlusion and treated with rt-PA in the First Affiliated Hospital of Nanjing Medical University from October 2017 to September 2018.According to the ASPECTS collateral circulation score,the patients were divided into two groups: good collateral group(n=31)and poor collateral group(n=18).The benefits and risks after thrombolysis in the two groups were compared,including 24-h NIHSS score,30-day mortality,90-day modified rankin scale(mRS)score,and the incidence of symptomatic cerebral hemorrhage.Statistical analysis was performed using t test,corrected x2 test,or Fisher's exact test.Results The 24-h NIHSS score and 90-day mRS score in the good collateral group were significantly lower than those in the poor collateral group(4.6±5.6 vs 12.5±8.4,P=O.OO; 1.7±1.7 vs 3.1±1.5,P<0.05).The incidence of NIHSS score improved by ≥50%and the incidence of 90-day mRS 0-2 was significantly higher in the good collateral group after 24 h of thrombolysis(77.4%vs 27.8%,P<0.05; 80.6%vs 27.8%,P=O.OO); The incidence of symptomatic cerebral hemorrhage was significantly lower in the good collateral group than in the poor group(9.7%vs 50.0%,P<0.05).There was no significant difference in mortality between the two groups after 30 days of thrombolysis(P>0.05),but the 30-day mortality of the poor collateral group was still greater than that of the good collateral group(11.1%vs 0%).Conclusion For patients with acute MCA infarction and receiving vascular recanalization therapy,patients with good collateral circulation can achieve good clinical outcomes,restore better recent neurological function,and obtain lower incidence of symptomatic cerebral hemorrhage and lower disability and mortality rate.

ABSTRACT

Objective To analyze the clinical characteristics and short-term prognostic factors in acute cerebral infarction patients who underwent recanalization. Methods This retrospective study enrolled 94 cases of acute cerebral ischemic patients in the First Affiliated Hospital of Nanjing Medical University between October 2014 and August 2016. Based on the clinical characteristics of the enrolled patients, a multivariate Logistic regression model was established to analyze the risk factors of unfavorable prognosis. Besides, patients were further divided into good collateral circulation group (1-2) and poor collateral circulation group (3-5) according to the Pial Collateral score, and the prognosis improvement rates between patients recanalized within 4 h and over 4 h were analyzed in each group. Chi-square test or Fisher's exact test was used to analyze statistical difference as indicated. Results By multivariate Logistic regression analysis, age older than 70 years old (OR=2.651, 95%CI: 1.013-6.937)and poor collateral circulation (OR=3.160, 95%CI: 1.113-8.977) were independent risk factors of short-term poor prognosis. In the poor collateral circulation subgroup, patients recanalized within 4 h exerted a relatively better prognosis than patients recanalized over 4 h (42.9% vs.10.5%, P=0.047). However, the effect of recanalization duration on the prognosis in the good collateral circulation subgroups was not statistically significant (42.9% vs. 10.5%, P=0.047), however, the effect of recanalization duration on prognosis in patients with good collateral circulation was not statistically significant (58.3% vs. 37.8%, P=0.117). Conclusions For patients with acute cerebral infarction, age and collateral circulation status may influence the prognosis of recanalization therapy. The treatment time had a significant influence on the prognosis in patients with poor collateral, while it had minimal significance on patients with good collateral.

ABSTRACT

Objective The goal of this study is to compare the prognosis of recombinant tissue plasminogen activator (rt-PA) thrombolysis for middle cerebral artery (MCA) occlusion with patients with good and poor cerebral collateral circulation.Methods This retrospective study included 49 patients diagnosed with acute MCA occlusion and treated with rt-PA in the First Affiliated Hospital of Nanjing Medical University between October 1,2014 and February 1,2016.Patients were divided into good collaterals group (n =31) and poor collaterals group (n =18) according to their distribution of leptomeningeal arteries with CTA.Thirty day mortality rate,the incidence of symptomatic intracranial hemorrhage,24h and 30 day Stroke scores with National Institute of Health Stroke Scale (NIHSS) were compared between the two groups.Corrected chi-squared test,Fisher's exact test,or t test was used to statistical analysis as appropriate.Results The 30 day mortality rate of good collaterals group was significantly lower than that of poor collaterals group (0% vs.16.7%,P < 0.05).There were no significant differences in the incidence of symptomatic intracranial hemorrhage and 24h NIHSS score between the two groups (P > 0.05),however,30 day NIHSS score of good collaterals group was significantly lower than that of poor collaterals group (7.2 ± 3.1 vs.9.6 ± 2.7,P < O.05).Conclusion For patients with MCA occlusion and receiving intravenous thrombolysis,good cerebral collateral circulation may reduce their mortality and improve their clinical outcome after thrombolysis.However,good cerebral collateral circulation does not reduce the risk of symptomatic intracranial hemorrhage in those patients.
