To further analyze immunoglobulin (Ig) properties of panel reactive antibodies (PRA) and their potential harmful effects on allogeneic renal transplants. Methods Since dithiothreitol (DTT) is able to crack disulphuric bond of Ig and to depoly-merize IgM with heavy molecular weight, PRA study was performed with treatment of DTT. Thus, a DTT-ERA method was established, which can identify immunoglobulin class in sera of high PRA patients. Results Among 701 recipients, whose sera were positive by the standard PRA, the positive rate of DTT-PRA was 33.2% . Besides, positive PRA patients could be divided into three groups according to their sera's sensitivity to DTT: Group 1 consisted of patients whose sera contained exclusively IgM antibodies; Group 2 consisted of patients whose sera contained of IgG antibodies only; Group 3 consisted of patients whose sera were found to contain both IgM class antibodies and IgG antibodies. Conclusion IgM class antibodies are not associated with posttrans-plant rejection, while IgG antibodies alone and mixture of IgG and IgM antibodies may mediate acute, or even hyperacute rejection.

Objective To establish a novel flow cytometric crossmatch assay allowing detection of complement-fixing donor specific anti-HLA IgG alloantibodies (Flow cytometry complement-dependent crossmatch,Flow-CDC). Methods One hundred pretransplant crossmatchings were performed using Flow-CDC and NIH-CDC between 62 patients awaiting renal transplantation and 33 donor cells.These crossmatchings were divided into two groups according to PRA.Group 1 consisted of 25 sera with negative PRA,and group 2 consisted of 75 sera with positive PRA.All of the sera were pretreated with DTT to inactivate IgM. Lymphocytes were isolated from peripheral blood (or,in a few instances,from the spleen) of the cadaveric donors. The correlation between different techniques for detection of donor specific anti-HLA antibodies was evaluated.The effect of both methods on clinical transplantation outcome was observed. Results In group 1,NIH-CDC and Flow-CDC were negative for all 25 sera.In group 2,24 (32.0%) had a positive NIH-CDC,31 (41.3%) had a positive Flow-CDC.There was a significant difference between two methods (?2=5.14, P= 0.016 ).Overall concordance between both tests was 93% with 69 concordant negatives and 24 concordant positives. The correlation coefficient (r) was 0.80.In group 2,5 patients received transplantation. One of them with negative NIH-CDC and positive Flow-CDC suffered from acute rejection after transplantation and lost the graft,and the other patients with negative NIH-CDC and Flow-CDC had good outcome. Conclusions Flow-CDC can detect specifically complement-fixing IgG alloantibodies against donor HLA and is more sensitive than NIH-CDC.Additionally,the computer printouts represent a permanent record of the crossmatch for retrospective review.Flow-CDC may become the standard crossmatch method as a possible alternative to conventional NIH-CDC testing.

Objective To better understanding the clinical presentations of phaeohyphomycosis,and improve the diagnosis and management of the disease.Methods We reported a case of pulmonary phaeohyphomycosis caused by Exophiala jeanselmei at the First Affiliated Hospital of Guangzhou Medical University in 2008,and reviewed the relevant literature.The clinical,radio-logical and etiological features were summarized based on this case and the other 23 phaeohyphomycosis patients reported in China from January 1995 to August 2013.Results 24 Chinese cases of phaeohyphomycosis have been reported to date,including 15 males and 9 females.The age of these patients ranged from 4 to 76 (mean 40.0±21 .8)years old.Seventeen patients were otherwise healthy.The other 7 patients had complications.Clinical presentations of phaeohyphomycosis vary widely,including cutaneous and subcutaneous infection in 18 cases,pulmonary and central nervous system involvement in two cases each,para-nasal sinus and palpebral conjunctiva infection one case each.The diagnosis of 18 cases were confirmed both microbiologically and histologically.One case was confirmed histologically alone.Five cases were identified microbiologically alone.The samples for culture were collected from skin abscess (1/5 ),pulmonary tissue (2/5 ),and cervical spinal fluid (2/5 ),respectively. Twenty-two strains of causative organisms were identified,7 of which were Exophiala jeanselmei .Twenty-three patients received treatment.They were cured by antifungal agents alone (18)or in conjunction with surgical resection (4 ),or assisted with XD-635AB-based photodynamic laser therapy (1).Specifically,10 pa-tients were cured by itraconazole alone.Conclusions In China, most patients of phaeohyphomycosis have concurrent conditions or have previously received immunosuppressive agents and cor-ticosteroids.Cutaneous and subcutaneous infection were most common,located mainly on limbs,face,chest and abdominal skin.The most frequently isolated pathogen is Exophiala jeanselmei ,followed by Phialophora verrucosa and Exophiala spinifera .Itraconazole therapy would be very effective.Susceptibility testing is very useful in case of refractory infection.

Objective To explore the relationship of serum anti-MICA antibody and development of chronic rejection (CR) after renal transplantation. Methods The enrolled 105 patients included 43 cases of CR, and 62 cases of functioning renal allograft as controls. Data including PRA level before transplantation, HLA mismatch, cold ischemic time, SCr at discharge, immunosuppressive regimen,and months after transplantation were analyzed. Blood samples were collected immediately after grouping for anti-MICA antibodies, SCr determination. Acute rejection episodes and renal allograft function which was evaluated by △SCr/M [(SCr at present - SCr at discharge) /months after transplantation) were compared between anti-MICA-antibody positive patients and anti-MICA-antibody negative patients. Results There was no significant difference in gender, age, HLA mismatch, cold ischemic time, immunosuppressive regimen, SCr at discharge, months after transplantation between CR and control groups (P>0.05). Serum creatinine level and number of antiMICA-antibody positive patients in CR group were significantly increased as compared with those in control group (P<0.01 ). Acute rejection episodes during the first 3 months after transplantation in anti-MICA-antibody positive patients were significantly more than those in anti-MICA-antibody negative patients (P<0.05),and the △SCr/M in the former was higher than that in the latter (8.3 +3.6 vs 2.4 ± 2.6, P<0.05). Conclusion Humoral immunoreaction mediated by MICA partly participates the development of CR after renal transplantation. MICA antibody is a risk factor affecting long-term allograft function.
