RESUMO
Objective To compare the clinical features of cytomegalovirus (CMV) infection and CMV disease after allogeneic hematopoietic stem-cell transplantation (HSCT) from HLA haploidentical related doors vs.HLA-matched sibling donors.Methods A total of 327 patients who received allogeneic HSCT from Jan.2011 to Dec.2011 were enrolled.There were 312 patients who had complete serological data before HSCT including 216 cases of HLA haploidentical related HSCT and 96 cases of HLA-matched sibling HSCT.Monitoring of CMV antigenemia was performed by using real-time quantitative (RQ) PCR after transplantation.Risk factors were compared by univariate and multivariate analysis.Results The cumulative incidence of CMV infection and CMV disease was (80.1 ± 2.7) ％ and (8.7 ± 2.0) ％ in HLA haploiddentical HSCT group,and (21.1 ± 4.9) ％ and 0 in HLA-matched sibling HSCT group respectively,and the difference was statistically significant between the two groups (P＜0.01).Univariate analysis revealed that HLA haploidentical related HSCT,less than 20 years of age,high risk disease,CMV-IgG serum positivity in patients or donors,acute graft-versus-host disease (aGVHD),EB viremia,and hemorrhagic cystitis were the risk factors of CMV infection.HLA haploidentical related SCT and hemorrhagic cystitis were the risk factors for CMV disease.Multivariate analysis showed that patients less than 20 years of age had a significantly high incidence of CMV infection.Patients from HLA-matched sibling HSCT,low risk disease,aGVHD,hemorrhagic cystitis had a significantly low incidence of CMV infection.Conclusion Compared with patients receiving HLA-matched sibling HSCT,those who received HLA haploidentical related HSCT had significantly high incidence of CMV infection and CMV disease,which were correlated with incidence of hemorrhagic cystitis.
RESUMO
Objective To study the diagnostic values of a distintegrin and metalloproteases-8 (ADAMS) in non-small cell lung cancer(NSCLC).Methods The serum protein level of ADAM8 was assayed by ELISA in 62 NSCLC patients,27 lung benign lesions and 32 healthy people.Results The serum levels of ADAM8 of NSCLC [(456.88±143.87)ng/L] were higher than those with lung benign lesions[ (271.63±74.20) ng/L] and normal controls(253.09±72.15 ng/L) (P<0.01), but there was no significant difference between lung benign lesions and normal controls (P0.05).No significant difference was found between adenocarcinoma and squamous cell carcinoma in serum ADAM8 level,the serum levels of ADAM8 in NSCLC with stages Ⅲ-Ⅳ [ (498.80 ± 151.80) ng/L] were higher than those with stages Ⅰ -Ⅱ[(385.80±95.85) ng/L] (P <0.01 ).The diagnostic sensitivity of detection of ADAM8 for NSCLC was 77.4% and the specificity was 90.6%.Conclusion The overexpression of ADAM8 in serum of NSCLC patients indicates that ADAM8 is related with occurrence and metastasis of NSCLC;De-tection of ADAM8 could assist the diagnosis for NSCLC.
