Objective Comprehensive mortality risk analyses and therapeutic assessment in real-world practice are beneficial to guide individual treatment in patients with Carbapenem-resistant Klebsiella pneumoniae bloodstream infections(CRKP-BSI).Methods Retrospective analysis of the clinical characteristics of 81 CRKP-BSI patients in our intensive care unit from July 2016 to June 2020,to indentify the risk factors of death and treatment effects of different antibiotic regimens.Results In 81 CRKP-BSI cases,the majority source were from abdominal and respiratory,accounting for 56.79%(46 cases)and 22.22%(18 cases),respectively.The 28-day mortality and hospitalization mortality of CRKP-BSI were 54.32%(44 cases)and 65.43%(53 cases).Multivariate regression analysis suggested that biliary tract disease before admission(P=0.026)and increased SOFA score at the onset of BSI(P=0.006)were independent risk factors for 28-day mortality.There was no statistically significant difference in 28-day mortality between the groups of antibiotic treatment based on tigecycline(44 cases)and polymyxin B(26 cases)[56.82%(25/44)vs.57.69%(15/26),P=0.943].Patients were evaluated based on their age(≤65 years vs.>65 years),gender,body mass index(≤25 kg/m2 vs.>25 kg/m2),and APACHEⅡ score(≤20 vs.>20),the use of renal replacement therapy and mechanical ventilation,there was no difference in the mortality among each subgroup.Conclusions Biliary tract disease before admission and SOFA score were independent risk factors for 28-day mortality.There was no significant difference outcomes between tigecycline-and polymyxin B-based therapy.

Objective:To explore the clinical features and prognosis of central nervous system involvement in patients with microscopic polyangiitis (MPA).Methods:We retrospectively investigated the clinical data of 138 MPA patients hospitalized with MPA in Tianjin Medical University General Hospital from January 1, 2010 to November 1, 2019. Patients were divided into two groups according to whether they had the central nervous system (CNS) involvement or not and then Kaplan-Meier survival curve was used to analyze the survival rate between the two groups, Logistic regression model analysis was adopted to analyze risk factors, and P<0.05 was considered statistically significant. Results:①29 patients (21.0%)among the 138 MPA had CNS-affected, including 13(44.8%) males and 16(55.2%) females. CNS involvement was present at the diagnosis of MPA in 20 cases (69.0%) and after the diagnosis of MPA in 9 cases (31.0%). ②The clinical manifestations were motor impairment in 14 cases (48.3%), sensory impairment in 10 cases (34.5%), speech loss in 9 cases (31.0%), headache in 8 cases (27.6%), consciousness disorder in 7 cases (24.1%), dysphagia and bucking in 4 cases (13.8%), cranial nerves involvement in 3 cases (10.3%). The imaging manifestations of the head included infarction, hemorrhage, infarction with hemorrhage and linear dural thickening. Five patients received lumbar puncture. One patient showed elevation of cerebrospinal fluid pressure, 1 patient had elevated protein and 5 patients showed elevation of LDH.③Eighteen patients received glucocortoid combined with cyclophosphamide. CNS symptoms recurred in 6 patients, four patients had recurrent cerebral infarction. ④Median survival time was 55 months in the CNS affected group [95% CI=(14.215, 95.785)] and 86 months in the N-CNS group [95% CI=(24.378, 147.622)]. Kaplan-Meier survival curve showed that there was no significant difference in survival rate between the two groups ( χ2=0.07, P=0.794) . Conclusion:The central nervous system involvement of microscopic polyangiitis is not uncommon. The clinical manifestations are various, with motor impairment the most. The most common imaging manifestation is cerebral infarction and the patients mainly presenteas multiple cerebral infarction. However, the CNS involvement of microscopic polyangiitis is not associated with mortality.

Objective:To investigate the clinical characteristics and prognosis of idiopathic inflammatory myopathy (IIM) patients with positive anti-melanoma differentiation-associated gene 5 (MDA5) antibody.Methods:A total of 194 hospitalized IIM patients who were tested for myositis-specific autoantibodies (MSAs) in the Departments of Rheumatology and Immunology of Tianjin Medical University General Hospital from January 2015 to September 2020 were collected, including 29 cases with positive anti-MDA5 antibody and 165 cases with negative anti-MDA5 antibody. Their clinical data were analyzed retrospectively. T test was used for measurement data with normal distribution. Measurement data with non-normal distribution were tested by Mann-Whitney U rank sum test. χ2 test was used for counting data. Risk factors were analyzed by binary Logistic regression, survival analysis by Kaplan-Meier method and Cox regression analysis. Results:IIM patients with positive anti-MDA5 antibody had a high incidence of dermatomyositis specific skin rash, and the skin rash was the most common presenting symptom. In the positive anti-MDA5 antibody group, muscle symptoms were mild; and the patients were prone to have fever, arthritis, oral ulcer and weight loss. All patients were complicated with interstitial lung disease (ILD). In patients with negative anti-MDA5 antibody, white blood cell (WBC) count [7.59(5.61, 9.89)×10 9/L vs 4.07(3.17, 5.50×10 9/L, Z=-5.05, P<0.001], platelet (PLT) [249.00 (200.00, 302.00)×10 9/L vs 205.00 (178.00, 244.00)×10 9/L, Z=-2.59, P=0.010], lymphocyte (LY) [1.34(0.85, 1.94)×10 9/L vs 0.64(0.40, 0.83)×10 9/L, Z=-5.78, P<0.001), serum creatine kinase (CK) [558.00 (72.00, 2 959.00) U/L vs 64.00 (35.00, 149.50) U/L, Z=-3.97, P<0.001], creatine kinase isoenzymes (CK-MB) [38.00 (17.00, 127.00) U/L vs 16.00 (14.00, 25.00) U/L, Z=-3.84, P<0.001], myoglobin (MYO) [243.65 (60.50, 829.83) ng/ml vs 34.55(21.00, 104.23) ng/ml, Z=-3.98, P<0.001], troponin T (TnT) [0.09(0.03, 0.44) ng/ml vs 0.02(0.01, 0.04) ng/ml, Z=-4.17, P<0.001], albumin (ALB) [34.00(30.00, 38.00) g/L vs 31.00 (26.50, 36.00) g/L, Z=-2.68, P=0.007], cluster of differentiation 4 (CD4) + T cells [498.00(276.00, 752.00) cells/μl vs 259.50 (179.00, 498.25) cells/μl, Z=-2.79, P=0.005], partial pressure of carbon dioxide (PaCO 2) [39.00(36.13, 42.00) mmHg vs 35.35 (31.30, 38.88) mmHg, Z=-3.75, P<0.001], partial pressure of oxygen (PaO 2) [82.00(71.90, 90.20) mmHg vs 73.25(64.30, 84.05) mmHg, Z=-2.08, P=0.037], arterial oxygen saturation (SaO 2) [96.50% (95.05%, 97.30)% vs 95.80%(93.70%, 96.55%), Z=-2.11, P=0.035], diffusion capacity for carbon monoxide of the Lung (DLco) [(63±21) % vs (52±14)%, t=0.96, P=0.006] were significantly reduced, while UTP [260.50 (172.25, 401.25) g vs 331.00 (252.75, 666.25) g, Z=-2.18, P=0.029], alanine aminotransferase (ALT) [40.00 (21.00, 83.00) U/L vs 56.00(40.00, 107.50), Z=-2.27, P=0.023], glutamyltranspeptidas (GGT) [22.50(15.00, 42.00) U/L vs 57.00 (38.00, 101.50) U/L, Z=-4.98, P<0.001], D-Dimer [850.00 (485.00, 1 799.50) ng/ml vs 1 346.00 (896.50, 2 527.00) ng/ml, Z=-2.55, P=0.011], immunoglobulin (Ig)E [60.00 (25.60, 147.50) U/ml vs 173.00(68.25, 471.50) U/ml, Z=-3.06, P=0.002], C4[20.25(16.68, 25.03) mg/L vs 23.60(20.20, 28.35) mg/L, Z=-2.38, P=0.017], Fer [228.01 (115.40, 513.36) ng/ml vs 1 636.39 (851.80, 3 888.82) ng/ml, Z=-6.01, P<0.001], krebsvondenlungen-6 (KL-6) [365.00 (180.25, 1 018.75) U/ml vs 788.00 (406.00, 1 364.00) U/ml, Z=-2.10, P=0.035] were higher when compared to patients with positive anti-MDA5 antibody. In the anti-MDA5 antibody positive group, patients had high mortality rate [8.5%(14/165) vs 34.5%(10/29), χ2=13.07, P<0.001], and the use of intravenous immunoglobulin [32.7%(54/165) vs 65.5%(19/29), χ2=11.30, P=0.001] and steroid pulse therapy [4.8%(86/165) vs 27.6%(8/29), χ2=13.98, P<0.001] were more frequent. Patients in the positive anti-MDA5 antibody group were classified into two sub groups based on lung features: the rapidly progressive interstitial lung disease (RP-ILD) group (48.28%, 14/29) and the chronic interstitial lung disease (C-ILD) group (51.72%, 15/29). RP-ILD patients had significantly elder disease onset age, higher C-reaction protein (CRP), Fer, IgE levels and the positive rate of anti-Ro52 antibody, while ALT was lower. The difference was statistically significant. Regression analysis suggested that older onset age [ HR (95% CI)=1.154 (1.069, 1.246), P<0.001], male [ HR(95% CI)=6.383(1.038, 39.242), P=0.045], positive anti-MDA5 antibody [ HR(95% CI)=17.180 (2.900, 101.766), P=0.002], LY decrease [ HR (95% CI)=0.083 (0.008, 0.817), P=0.033], high serum Fer level [ HR (95% CI)=1.001(1.000, 1.001), P=0.016], increased D-Dimer [ HR(95% CI)=1.000(1.000, 1.001), P=0.004] and compicated with carcinoma [ HR (95% CI)=11.849 (1.978, 70.970), P=0.007] were independent risk factors for death in IIM patients. Binary logistic regression analysis suggested that late onset age [ OR(95% CI)=1.090 (1.005, 1.183), P=0.038], high Fer level [ OR (95% CI)=1.001 (1.000, 1.001), P=0.022] and decreased ALB [ OR (95% CI)=0.818 (0.696, 0.963), P=0.016] might be risk factors for RP-ILD in patients with positive anti-MDA5 antibody. Conclusion:In patients with positive anti-MDA5 antibody group, typical skin damage, mild muscle symptoms, high proportion of ILD and poor prognosis are chardcteristic when compared to patients without this autoantibody. It is necessary to monitor the disease activity closely and explore the treatment strategy.

Objective To evaluate an effective and feasible quantitative evaluation table of traditional Chinese medicine (TCM) syndrome differentiation, and to observe the effect of combination of TCM syndrome differentiation and standard bundle therapy in patients with septic shock. Methods A prospective randomized controlled trial was conducted. The septic shock patients with acute deficiency syndrome admitted to department of critical care medicine of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from January 1st, 2016 to December 31st, 2017 were enrolled. The patients were randomly divided into control group and Shenfu group. The patients in both groups received early application of standardized bundle therapy; those in Shenfu group received 60 mL Shenfu injection infusion in addition for 7 days. The TCM syndrome score was evaluated by classification and scoring method of TCM symptoms. The circulation and tissue perfusion, severity of disease, organ function, inflammation response, adjuvant treatment and 28-day mortality were compared between the two groups. Results A total of 50 patients with septic shock were enrolled in the analysis, 25 in control group and 25 in Shenfu group. The markedly effective rate of TCM symptoms score in Shenfu group was significantly higher than that in control group [60.0% (15/25) vs. 16.0% (4/25), P < 0.01]. There was no significant difference in all parameters before treatment between the two groups. After treatment, the observation indexes of both groups were improved. Compared with control group, the mean arterial pressure (MAP) in Shenfu group increased more significantly [mmHg (1 mmHg = 0.133 kPa): 13.0 (2.5, 28.5) vs. 6.0 (0, 13.5)], the lactate (Lac) and procalcitonin (PCT) decreased more significantly [Lac (mmol/L): 0.8 (0.1, 3.7) vs. 0.5 (-0.6, 1.7), PCT (μg/L): 2.0 (0.7, 32.3) vs. 0 (-1.8, 3.8)], activated partial thromboplastin time (APTT) was shortened more significantly [s: 8.5 (0, 12.9) vs. 0 (-7.2, 10.0)], and interleukins (IL-2 receptor and IL-6) levels decreased more significantly [IL-2 receptor (ng/L):1 031.0 (533.0, 1 840.0) vs. 525.5 (186.0, 1 166.8), IL-6 (ng/L): 153.1 (21.4, 406.8) vs. 35.1 (16.3, 110.1)] with significant differences (all P < 0.05). There was no significant difference in the use time of vasoactive drugs, duration of mechanical ventilation, severity of the disease or 28-day mortality between the two groups. However, the use time of vasoactive drugs in Shenfu group was shorter than that in control group (days: 5.48±4.81 vs. 8.28±7.83), and the 28-day mortality was decreased [8.0% (2/25) vs. 20.0% (5/25)]. Conclusions TCM syndrome score is helpful to evaluate the effect of TCM syndrome differentiation and treatment, and it is effective and feasible in clinical application. Septic shock patients treated with TCM syndrome differentiation and treatment combined with standard bundle therapy were significantly improved in circulation, tissue perfusion, coagulation function and inflammation reaction.
