ABSTRACT
Objective:To explore the clinical characteristics of acquired immunodeficiency syndrome (AIDS) complicated with nontuberculous mycobacteria (NTM) disease.Methods:The clinical data of 190 patients with AIDS complicated with NTM disease diagnosed by Shanghai Public Health Clinical Center, Fudan University from January 1, 2019 to December 31, 2021 were analyzed retrospectively. NTM diseases were divided into disseminated NTM disease group and non-disseminated NTM disease group. The independent sample t test, Mann Whitney U test and chi-square test were used for statistical analysis. Results:The 190 patients with AIDS complicated with NTM disease included 182 males and eight females. The age was (42±13) years old, and the first hospital stay was 15(6, 26) days. Pneumocystis carinii pneumonia was the most common co-infection in 12.1%(23/190) of patients, 87 cases (45.8%) were disseminated NTM disease. The clinical symptoms of patients were common in fever (55.8%(106/190)), cough (50.0%(95/190)), and expectoration (28.9%(55/190)). The proportions of fatigue (31.0%(27/87) vs 7.8%(8/103)), poor appetite (21.8%(19/87) vs 10.7%(11/103)) in the AIDS patients with disseminated NTM disease group were higher than those in the non-disseminated NTM disease group, and the differences were statistically significant ( χ2=16.99, P<0.001 and χ2=4.42, P=0.036, respectively). There was no significant difference in the proportions of deaths between AIDS patients with disseminated NTM disease and those without disseminated NTM disease (17.2%(15/87) vs 12.6%(13/103), χ2=0.80, P=0.371). The most common NTM species was Mycobacterium avium (67.1%(49/190)), followed by Mycobacterium kansasii (15.1%(11/190)). Hemoglobin ((90.3±23.9) g/L vs (110.1±24.2) g/L), albumin ((29.7±5.5) g/L vs (34.7±5.6) g/L), CD4 + T lymphocyte count (11(5, 30)/μL vs 52(16, 96)/μL) and CD8 + T lymphocyte count ((362±320)/μL vs (496±352)/μL) in the disseminated NTM disease group were lower than those in non-disseminated NTM disease group ( t=-5.63, P<0.001; t=-6.18, P<0.001; Z=-5.90, P<0.001; and t=-2.73, P=0.007, respectively), while procalcitonin (0.24(0.10, 0.77) μg/L vs 0.10 (0.04, 0.51) μg/L) was higher than that in the non-disseminated NTM disease group ( Z=-3.09, P=0.002), with statistical significance. The most common imaging features were lung patch and strip shadow (67.4%(128/190)). Conclusions:The most common type of AIDS patients complicated with NTM disease is disseminated NTM disease, and Mycobacterium avium is the most common NTM species. The clinical manifestations (fatigue, anorexia) and laboratory tests (hemoglobin, albumin, procalcitonin, CD4 + T lymphocyte count, CD8 + T lymphocyte count) of AIDS patients with disseminated NTM disease and non-disseminated NTM disease are different, while the prognosis is not significantly different.
ABSTRACT
Objective:To analyze the clinical and epidemiological characteristics and changing trends of acquired immunodeficiency syndrome (AIDS)-associated talaromycosis in Shanghai City.Methods:The clinical data of patients with AIDS-associated talaromycosis hospitalized at Shanghai Public Health Clinical Center, Fudan University from Janauary 1, 2014 to December 31, 2021 were collected. The medical information included age, gender, place of origin, clinical symptoms, imaging manifestations, blood routine test, CD4 + T lymphocyte count. The chi-square test or Fisher exact probability test was used for statistical analysis. Univariate logistic regression was used to analyze the related risk factors for death. Results:From 2014 to 2021, a total of 12 165 AIDS patients were admitted, including 169 (1.4%) AIDS-assiociated talaromycosis patients. The proportions of AIDS-associated talaromycosis in AIDS inpatients from 2014 to 2021 were 1.8%(21/1 149), 1.1%(14/1 307), 1.3%(19/1 446), 0.9%(15/1 610), 1.2%(20/1 626), 1.2%(22/1 778), 1.7%(28/1 624) and 1.8%(30/1 625), respectively, which had not changed much. There was no statistically significant difference in the proportion of AIDS-associated talaromycosis in AIDS inpatients in different years ( χ2=9.50, P=0.218). Among the 169 patients, 157 cases (92.9%) were male, with the age of (37.9±12.2) years, and 35 were from Jiangxi Province, 31 from Shanghai Municipality, 29 from Zhejiang Province, 17 from Anhui Province, 14 from Fujian Province, 11 from Jiangsu Province, eight from Hunan Province, four from Heilongjiang Province, three cases each from Guangxi Zhuang Autonomous Region, Guizhou Province and Henan Province, two cases each from Hubei Province, Shandong Province, Shanxi Province, Yunnan Province and Guangdong Province, and one case from Chongqing Municipality. Patients from non-traditional endemic areas did not find a clear history of living in traditional endemic areas. Of 169 patients, 143(84.6%) cases had fever, 73(43.2%) had respiratory symptoms, and 26(15.4%) had rash during the course of the disease, 147(87.0%) had pulmonary imaging abnormalities, 94(55.6%) were complicated by other pathogens, and 44(26.0%) had hepatosplenomegaly, 137(81.1%) had CD4 + T lymphocyte count <50/μL. Twenty-three patients died, with the total fatality rate of 13.6%. The overall mortality rate showed a downward trend year by year. There was a statistically significant difference in the case fatality rate of AIDS-associated talaromycosis in different years (Fisher exact probability test, P=0.046). The result of univariate logistic regression model showed that patients with platelet count<50×10 9/L had an increased risk of death (odds ratio ( OR)=3.33, 95% confidence interval ( CI) 1.13 to 9.81, P=0.029). Conclusions:The overall change of AIDS-associated talaromycosis inpatients in Shanghai is not significant, while the prevalence rate has increased slightly in recent two years. The case fatality rate is declining year by year. The proportions of patients without a history of living in or traveling to epidemic areas and without rash as the first manifestation are high, and the main clinical manifestation is multi-system damage. Patients with platelet count<50×10 9/L have an increased risk of death.
ABSTRACT
Objective To analyze the clinical features of patients with coronavirus disease 2019 (COVID-19) in Shanghai and to investigate the risk factors for disease progression to severe cases. Methods The clinical data of 292 adult patients with COVID-19 hospitalized in Shanghai Public Health Clinical Center from January 20, 2020 to February 10, 2020 were retrospectively analyzed, including 21 severe patients and 271 mild patients. The demographic characteristics, epidemiological history, history of underlying diseases and laboratory examinations were compared between the two groups. Measurement data were compared using t test or Mann-Whitney U test. The count data were compared using hi-square test. The binary logistic regression equation was used to analyze the risk factors for the progression of patients to severe cases. Results Among the 292 patients, 21 were severe cases with the rate of 7.2% (21/292). One patient died, and the mortality rate was 4.8% in severe patients. The severe patients aged (65.0±15.7) years old, 19 (90.5%) were male, 11 (52.4%) had underlying diseases, 7 (33.3%) had close relatives diagnosed with COVID-19. The mild patients aged (48.7±15.7) years old, 135 (49.8%) were male, 74 (27.3%) had underlying diseases, 36 (13.3%) had close relatives diagnosed with COVID-19. The differences between two groups were all significant statistically ( t =-4.730, χ 2 =12.930, 5.938 and 4.744, respectively, all P <0.05). Compared with the mild patients, the levels of absolute numbers of neutrophils, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatinine, serum cystatin C, C reactive protein (CRP), procalcitonin , D -dimer, pro-B-type natriuretic peptide (proBNP), serum myoglobin, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), serum troponin I (cTnI) in severe patients were all significantly higher ( U =2 091.5, 1 928.0, 1 215.5, 729.0, 1 580.5, 1 375.5, 917.5, 789.5, 1 209.0, 1 434.0, 638.0, 964.5, 1 258.0 and 1 747.5, respectively, all P <0.05), while the levels of lymphocyte count, albumin, transferrin, CD3 + T lymphocyte count, CD8 + T lymphocyte count and CD4 + T lymphocyte count in severe patients were all significantly lower ( U =1 263.5, t =4.716, U =1 214.0, 962.0, 1 167.5 and 988.0, respectively, all P <0.05). Further logistic regression analysis showed that the albumin (odds ratio ( OR )=0.806, 95% CI 0.675-0.961), CRP ( OR =1.016, 95% CI 1.000-1.032), serum myoglobin ( OR =1.010, 95% CI 1.004-1.016), CD3 + T lymphocyte count ( OR =0.996, 95% CI 0.991-1.000) and CD8 + T lymphocyte count ( OR =1.006, 95% CI 1.001-1.010) at admission were independent risk factors for the progression of COVID-19 patients to severe illness (all P <0.05). Conclusions Severe cases of patients with COVID-19 in Shanghai are predominantly elderly men with underlying diseases. Albumin, CRP, serum myoglobin, CD3 + T lymphocyte count and CD8 + T lymphocyte count could be used as early warning indicators for severe cases, which deserve more clinical attention.
ABSTRACT
Objective:To analyze the effects of angiotensin converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) on coronavirus disease 2019 (COVID-19) patients with hypertension, and to provide an evidence for selecting antihypertensive drugs in those patients.Methods:Clinical data were retrospectively analyzed in 58 COVID-19 patients with hypertension admitted to Shanghai Public Health Clinical Center from January 20 to February 22, 2020, including epidemiological history, clinical manifestations, laboratory findings, chest CT and outcome. Patients were divided into ACEI/ARB group and non-ACEI/ARB group.Results:Twenty-six patients were in ACEI/ARB group and the other 32 patients in non-ACEI/ARB group, with median age 64.0 (49.5, 72.0) years and 64.0 (57.0, 68.8) years respectively. The median time to onset was 5(3, 8) days in ACEI/ARB group and 4 (3, 7) days in non-ACEI/ARB group, the proportion of patients with severe or critical illness was 19.2% and 15.6% respectively. The main clinical symptoms in two groups were fever (80.8% vs. 84.4%) and cough (23.1% vs. 31.3%). The following parameters were comparable including lymphocyte counts, C-reactive protein, lactate dehydrogenase, D-dimer, bilateral involvement in chest CT (76.9% vs. 71.9%), worsening of COVID-19 (15.4% vs. 9.4%), favorable outcome (92.3% vs. 96.9%) between ACEI/ARB group and non-ACEI/ARB group respectively (all P>0.05). However, compared with non-ACEI/ARB group, serum creatinine [80.49 (68.72, 95.30) μmol/L vs. 71.29 (50.98, 76.98) μmol/L, P=0.007] was higher significantly in ACEI/ARB group. Conclusions:ACEI/ARB drugs have no significant effects on baseline clinical parameters (serum creatine and myoglobin excluded) , outcome, and prognosis of COVID-19 patients with hypertension. Antihypertensive drugs are not suggested to adjust in those patients, but the potential impairment of renal function as elevation of serum creatinine should be paid attention in patients administrating ACEI/ARB drugs.
ABSTRACT
Objective:To summarize the clinical features of patients with Klebsiella pneumoniae pyogenic liver abscess(KP-PLA). Methods:Clinical data of 133 patients with pyogenic liver abscess(PLA) and positive results of blood or pus culture were retrospectively analyzed in Huashan Hospital Affiliated to Fudan University from 2009 to 2018. According to the culture results, patients were divided into KP-PLA group ( n=92) and non-KP-PLA group ( n=41). Results:KP-PLA and non-KP-PLA were similar in gender composition with males accounting for 67.39% and 70.73%, and had age of (56.8±13.8) years and (55.0±13.0) years (χ 2=0.146, 0.708, P>0.05) respectively. The underlying diseases were more common in KP-PLA group, including diabetes accounting for 45.65% and 24.39%, and hypertension accounting for 32.61% and 14.63% (χ 2=5.384, 4.642, P<0.05) respectively. Patients with KP-PLA had more invasive infections beyond liver than those with non-KP-PLA, which were 27.17% and 9.76% (χ 2=5.046, P=0.025). The laboratory results showed that hemoglobin levels in KP-PLA and non-KP-PLA were (109.88±20.97) g/L and (97.75±20.25) g/L ( t=3.086, P=0.002). Serum alkaline phosphatase levels were 146.50 (114.50, 237.50) U/L and 220.50 (120.00, 316.75) U/L in KP-PLA and non-KP-PLA ( U=2 239.500, P=0.048) patients. Conclusions:KP-PLA mainly develops in middle-aged and elderly men, especially those with diabetes and hypertension. Patients with KP-PLA need to be paid more attention for invasive manifestations beyond liver.

Measurement data were compared using t test or Mann-Whitney U test. The count data were compared using chi-square test. The binary logistic regression equation was used to analyze the risk factors for the progression of patients to severe cases. Results:Among the 292 patients, there were 21 severe cases with the rate of 7.2%. One patient died, and the mortality rate was 4.8% in severe patients. The severe patients aged (65.5±15.7) years old, and 19 (90.5%) were male, 11 (52.4%) had underlying diseases, seven (33.3%) had close relatives diagnosed with COVID-19. The mild patients aged (48.7±15.7) years old, and 135 (49.8%) were male, 74 (27.3%) had underlying diseases, 36 (13.3%) had close relatives diagnosed with COVID-19. The differences between two groups were all significant statistically ( t=-4.730, χ2=12.930, 5.938 and 4.744, respectively, all P<0.05). Compared with the mild patients, the levels of absolute numbers of neutrophils, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatinine, serum cystatin C, C reactive protein (CRP), procalcitonin, D-dimer, pro-B-type natriuretic peptide (proBNP), serum myoglobin, creatine kinase (CK), creatine kinase isoenzyme (CK-MB), serum cardiactroponin I (cTn I) in severe patients were all significantly higher ( U=2 091.5, 1 928.0, 1 215.5, 729.0, 1 580.5, 1 375.5, 947.5, 789.5, 1 209.0, 1 434.0, 638.0, 964.5, 1 747.5 and 1 258.0, respectively, all P<0.05), while the levels of lymphocyte count, albumin, transferrin, CD3 + T lymphocyte count, CD8 + T lymphocyte count and CD4 + T lymphocyte count in severe patients were all significantly lower ( U=1 263.5, t=4.716, U=1 214.0, 962.0, 1 167.5 and 988.0, respectively, all P<0.05). Further logistic regression analysis showed that the albumin (odds ratio ( OR)=0.806, 95% confiderce interval ( CI)0.675-0.961), serum myoglobin ( OR=1.010, 95% CI 1.004-1.016), CRP ( OR=1.016, 95% CI 1.000-1.032), CD3 + T lymphocyte count ( OR=0.996, 95% CI 0.991-1.000) and CD8 + T lymphocyte count ( OR=1.006, 95% CI 1.001-1.010) at admission were independent risk factors for the progression of COVID-19 patients to severe illness (all P<0.05). Conclusions:Severe patients with COVID-19 in Shanghai are predominantly elderly men with underlying diseases. Albumin, CRP, serum myoglobin, CD3 + T lymphocyte count and CD8 + T lymphocyte count could be used as early warning indicators for severe cases, which deserve more clinical attention.
ABSTRACT
Objective To explore the clinical characteristics,drug resistance and prognosis of Klebsiella pneumoniae bloodstream infection (KP-BSI),and to analyze the risk factors of death and drug resistance.Methods The clinical data of hospitalized patients with KP-BSI from April 2015 to April 2017 in Huashan Hospital were retrospectively analyzed.Continuous variables were compared using t test.Categorical variables were compared using x2 test or Fisher exact test.The independent risk factors for death were determined by logistic regression model.Results The majority of the 74 patients with KP-BSI were male (67.6％) and elderly patients (78.4％).Nosocomial infection occurred in 58 cases (78.4％) and a total of 24 (32.4％) cases died.The patients were widely distributed in various departments of the hospital.The first was the Department of Infectious Diseases (29.7％),followed by the intensive care unit (23.0％).The patients were often complicated with various underlying diseases and the most common was pulmonary infection (56.8％).There were 45 (60.8％) multiple drug resistance (MDR) strains and 29 (39.2％) Carbapenems resistant Klebsiella pneumoniae (CRKP) strains.There were significant differences of nosocomial infections (x2 =4.655,P =0.031),deep venous catheters (x2 =5.432,P-0.02),and invasive mechanical ventilation (x2 =7.630,P =0.006) between MDR and non-MDR patients.Deep venous catheters (x2 =5.923,P=0.015),invasive mechanical ventilation (x2 =16.845,P=0.000),other catheters (x2 =4.009,P=0.045) and surgery (x2 =3.910,P=0.048) were all significantly different between CRKP and non-CRKP patients.APACHE Ⅱ scores were performed in all patients.The average APACHE Ⅱ score was 8.74-±5.32 of the 50 cases (67.6％) in the survival group and that was 16.46 ± 6.62 of the 24 cases (32.4％) in the death group.The APACHE Ⅱ score in the survival group was significantly lower than that in the death group.The difference was statistically significant (t=5.091,P=0.000).APACHE Ⅱ ≥15 was the independent factor of death (B =-2.708,P=0.000).Conclusions The situation of drug-resistant KP-BSI is severe in the clinic.According to the clinical data,nosocomial infections,invasive mechanical ventilation and deep venous catheters may be the risk factors for MDR bloodstream infection.Deep venous catheters,invasive mechanical ventilation,other catheters and surgery may be the risk factors for bloodstream infection with CRKP.APACHE Ⅱ ≥15 is the independent risk factor for death.The evaluation of APACHE Ⅱ score may predict the prognosis of patients with bloodstream infection.
