ABSTRACT
Objective:To analyze the clinical features of acquired immunodeficiency syndrome (AIDS) patients complicated with peripulmonary occupational lesions.Methods:Fifty-five AIDS patients with peripulmonary occupational lesions treated in Guangzhou Eighth People′s Hospital from January 2012 to January 2019 were included, and the clinical data of patients were retrospectively analyzed. According to the results of lung biopsy, the patients were divided into Mycobacterium infection group, fungal infection group and tumor group. The clinical characteristics, the proportion of different CD4 + T lymphocyte counts and chest computed tomography (CT) features of the three groups were compared. Chi square test was used for comparison among the three groups, and Bonferroni method was used to correct the test level for pairwise comparison. The significance level was 0.016 7 because of three pairwise comparisons. Results:Among 55 AIDS patients complicated with peripulmonary occupational lesions, pulmonary biopsy showed 14 cases with Mycobacterium infection, 12 cases with fungal infection and 15 cases with tumor lesions. Mixed diseases were found in 11 patients, including seven cases with Mycobacterium and fungus coinfection, four with tumor complicated with fungus and (or) Mycobacterium. Three with chronic interstitial pneumonia. The main clinical manifestations of 55 patients were fever, expectoration, fatigue, weight loss and superficial lymph node enlargement. There were no significant differences in symptoms/signs, white blood cell counts, hemoglobin levels, alanine transaminase and creatinine among Mycobacterium infection group, fungal infection group and tumor group (all P>0.05). There was significant difference in anti-retroviral therapy (ART) acceptance among the three groups ( χ2=15.165, P<0.01). However, the results of pairwise comparison between groups showed that there was significant difference between fungal infection group and tumor group ( χ2=7.514, P<0.016 7), while there was no significant difference between Mycobacterium infection group and tumor group, Mycobacterium infection group and fungal infection group ( χ2=0.255 and 5.306, respectively, both P>0.016 7). There were significant differences in clinical outcomes among the three groups ( χ2=15.119, P<0.01), and the pairwise comparison between the Mycobacterium infection group and the tumor group, and the fungal infection group and the tumor group showed significant differences ( χ2 =10.311 and 9.095, respectively, both P<0.016 7). The cases with CD4 + T lymphocyte count ≤50/μL, 51-<200/μL and ≥200/μL in Mycobacterium infection group were three cases, one case and 10 cases, respectively; those in fungal infection group were 10 cases, two cases and 0 case, respectively, and those in tumor group were one case, two cases and 12 cases, respectively. The difference was statistically significant ( χ2=21.284, P<0.01). Chest CT showed that there was significant difference in the types of space occupying lesions among the three groups ( χ2=13.308, P=0.003), and pairwise comparison between the two groups showed that there was significant difference between the Mycobacterium infection group and the tumor group ( χ2=11.312, P<0.016 7), while there were no significant differences between the Mycobacterium infection group and fungal infection group ( χ2=0.931, P>0.016 7), and the fungal infection group and the tumor group ( χ2=7.053, P>0.016 7). There was significant difference among the three groups in calcification focus ( χ2=8.524, P=0.004), while there was no difference between the Mycobacterium infection group and fungal infection+ tumor group ( χ2=10.982, P<0.016 7). Conclusions:Mycobacterium infection, fungal infection and tumor are the main types of peripulmonary occupational lesions in AIDS patients. The differential diagnosis could be made by combining with chest CT features, ART acceptance and CD4 + T lymphocyte level.
ABSTRACT
Objective To observe the changes of tongue and pulse parameters in the patients with chronic hepatitis B(CHB)after pegylated interferon alpha-2a(PEG-IFNα-2a)treatment,to investigate its value in evaluation clinical efficacy of PEG-IFNα-2a treatment.Methods 120 patients with CHB who confirmed to the standard received PEG-IFNα-2a antiviral therapy for 48 weeks,and followed up for 24 weeks.The tongue and pulse parameters were detected by DS01-A type digital tongue and pulse presentation analyzer.The changes of liver function,serum HBV markers,HBV DNA,tongue and pulse parameters were observed before and after treatment.Results 113 patients completed the course of treatment,46 cases received complete response(response rate 40.7%).The response rate of liver stagnation and spleen deficiency group was higher than that of blood stasis group(95%CI:0.010-0.677,P 0.05;W/t,t′=0.688,P >0.05;R,t =1.317,P =0.190;G,t =0.346,P =0.729;B,t =1.720,P =0.088).After 48 weeks treat-ment,and followed up for 24 weeks,the tongue and pulse parameters of response group and non response group were compared with baseline,h3 /h1,h4 /h1 decreased,R value and G value increased,the differences were statistically sig-nificant(Response group:h3 /h1,t =3.004,P =0.003;h4 /h1,t =2.702,P =0.008;R,t′=2.258,P 0.05;h4 /h1,t =0.390,P =0.697 2;h5 /h1,t′=0.957,P >0.05;W/t,t =0.149,P =0.881;R,t =1.343,P =0.181;G,t =0.994,P =0.322;B,t =0.565,P =0.572).Conclusion The changes of tongue and pulse parameters have improved after treatment with PEG-IFNαin patients with CHB. However,the value in predicting the efficacy of antiviral therapy may be limited.
ABSTRACT
Objective To explore the risk factors for the prognosis of acquired immunodeficiency syndrome (AIDS)-related lymphoma (ARL).Methods A total of 32 patients with ARL were enrolled in this study from Guangzhou Eighth People's Hospital during August 2011 and July 2014,who were followed up for 2 to 48 months (median 9 months).The risk factors for the prognosis of ARL were analyzed by Logistic regression analysis.Results A total of 32 patients were included,among whom 27 were males and the rest were females,with a mean age of (42.8± 13.5) years (ranging from 4 to 70 years).Regarding the clinical staging at the initial diagnosis,6 cases (18.8 ％) were classified as stage Ⅰ,4 cases (12.5％) stage Ⅱ,5 cases (15.6％) stage Ⅲ,and 17 cases (53.1％) stage Ⅳ.As for international prognostic index (IPI) score,4 cases (12.5％) were in the low risk group (IPI 0-1),5 cases (15.6％) in the low-middle group (IPI 2),8 cases (25.0％) in the middle-high risk group (IPI 3),and 15 cases (46.9 ％) in the high risk group (IPI 4-5).According to the pathological diagnosis,26 cases (81.2％) were B cell non-Hodgkin lymphoma (NHL),4 cases (12.5％) were T cell NHL,and 2 cases (6.2％) were Hodgkin lymphoma (HL) nodular sclerosis.In total,23 cases (71.9％) had received highly active antiretroviral therapy (HAART) before the first hospital visit or within one month after the diagnosis of lymphoma.Sixteen (50.0％) cases received standard chemotherapy regimen formulated by the oncology specialists.A total of 17 patients died,with the mortality rate of 53.1％.By univariate analysis,the prognostic factors included age (OR=0.915,P=0.012),high lactate dehydrogenase (OR=1.006,P=0.021) value at baseline,receiving HAART (OR =12.444,P=0.011),and standard chemotherapy regimen (OR=13.000,P=0.001).By multivariate Logistic regression,receiving standard chemotherapy regimen (OR=0.035,P=0.022) was the only prognostic factor of ARL.Conclusions The mortality of ARL is high and the most common pathological type was NHL.The prognosis could be improved by standard chemotherapy regimen on the basis of HAART.
ABSTRACT
Objective To analyse the effect of antivirus treatment on the survival time of chronic severe hepatitis B retrospectively.Methods one hundred and twenty-one patients with chronic severe hepatitis B and positive HBV DNA were divided into 3 groups:42 patients in entecavir(ETV)group,34 patients in lamivudine(LVD)group and 45 patients in control group.The primary data were recorded and followed.The survival curve was described using Kaolain-Maier method.The comparison of survival rate among groups was done using Logrank test.Results The baseline characteristics were well balanced among 3 groups.When the follow-up ended,the mean survival time of ETV group,LVD group and control group was(49.4±5.8)weeks,(51.6±6.7)weeks,(32.8±5.7)weeks;the total survival rate was 0.567,0.557,0.318 respectively,there was a statistical difference between ETV group and control grouP(χ2=5.742,P<0.05),or between LVD group and control group (χ2=5.472,P<0.05).There was not statistical difference between ETV group and LVD group in the week of 2,4,8,12,24,48.Conclusion ETV and LVD can improve the survival rate of chronic severe heoatitis B,and ETV iS not different from LVD.
