BACKGROUND: Lung cancer is the leading cause of cancer-related death, of which non-small cell lung cancer (NSCLC) is the most common type. Immune checkpoint inhibitors (ICIs) have now become one of the main treatments for advanced NSCLC. This paper retrospectively investigated the effect of peripheral blood inflammatory indexes on the efficacy of immunotherapy and survival of patients with advanced non-small cell lung cancer, in order to find strategies to guide immunotherapy in NSCLC. METHODS: Patients with advanced non-small cell lung cancer who were hospitalized in The Affiliated Cancer Hospital of Nanjing Medical University from October 2018 to August 2019 were selected to receive anti-PD-1 (pembrolizumab, sintilimab or toripalimab) monotherapy or combination regimens. And were followed up until 10 December 2020, and the efficacy was evaluated according to RECIST1.1 criteria. Progression-free survival (PFS) and overall survival (OS) were followed up for survival analysis. A clinical prediction model was constructed to analyze the predictive value of neutrophil-to-lymphocyte ratio (NLR) based on NLR data at three different time points: before treatment, 6 weeks after treatment and 12 weeks after treatment (0w, 6w and 12w), and the accuracy of the model was verified. RESULTS: 173 patients were finally included, all of whom received the above treatment regimen, were followed up for a median of 19.7 months. The objective response rate (ORR) was 27.7% (48/173), the disease control rate (DCR) was 89.6% (155/173), the median PFS was 8.3 months (7.491-9.109) and the median OS was 15.5 months (14.087-16.913). The chi-square test and logistic multi-factor analysis showed that NLR6w was associated with ORR and NLR12w was associated with ORR and DCR. Further Cox regression analysis showed that NLR6w and NLR12w affected PFS and NLR0w, NLR6w and NLR12w were associated with OS. CONCLUSIONS In patients with advanced non-small cell lung cancer, NLR values at different time points are valid predictors of response to immunotherapy, and NLR <3 is often associated with a good prognosis.

To investigate the correlation between peripheral concentration of infliximab (IFX) or anti-IFX antibody titers and short-term therapeutic effect of IFX in patients with active rheumatoid arthritis (RA).
 Methods: Twenty patients with active RA were treated with combination of methotrexate (MTX), leflunomide (LEF) with IFX, and the clinical and laboratory index and the side effects were recorded before and after IFX treatment. Twenty healthy subjects were chosen as a control group.
 Results: After 14-week treatment, patients were categorized into good, moderate or no responders according to EULAR remission criteria. There were no significant differences in peripheral IFX concentration, anti-IFX antibody titers and TNF-α levels among the 3 groups, and there were no significant correlations among ΔDAS28-CRP, peripheral IFX concentration, anti-IFX antibody titers and TNF-α levels.
 Conclusion: Peripheral IFX concentration, anti-IFX antibody titers and TNF-α levels can not be used as reliable predictive index for short-term effect of IFX in active RA.

OBJECTIVETo evaluate the efficiency and safety of rituximab and dexamethasone combined with cyclophosphamide for treating patients with relapsed and refractory immune thrombocytopenia (ITP).

METHODSTwelve patients with relapsed and refractory immune thrombocytopenia were prospectively enrolled in this study, and received rituximab 375 mg/m(2) once a week for 4 weeks, dexamethasone 40 mg once a day for consecutive 4 days, and cyclophosphamide 500 mg/m(2) biweekly for 2 weeks. The levels of IFN-r and IL-4 in peripheral blood of patients were measured by enzyme-linked immunosorbent assay (ELISA), and the percentages of Breg, Treg and Th17 cells were detected by flow cytometry before and after treatment. Efficiency was evaluated according to platelet counts, and side effects were observed.

RESULTSSix out of 12 patients reached to complete remission and 4 patients reached to partial remission, with the total response rate 83.33%. The platelet counts [(115.42 ± 76.60) × 10(9)/L] after treatment were significantly higher than that before treatment [(115.42 ± 76.60) × 10(9)/L] (P < 0.001). The ratio of IFN-r/ IL4 after treatment (5.89 ± 2.30) was very significantly lower than that before treatment (7.00 ± 2.73) (P = 0.002). The percentage of Breg cells after treatment [(21.27 ± 4.28)%] were much significantly higher than that before treatment [(15.48 ± 1.67)%] (P < 0.001). The ratio of Treg/Th17 after treatment (3.07 ± 1.50) was significantly higher than that before treatment (0.98 ± 0.45) (P < 0.001). Infusion reaction was observed in 1 patient, secondary hypertension and hyperglycemia were in 1 patient, and pneumonia in 2 patients.

CONCLUSIONRituximab and dexamethasone combined with cyclophosphamide can improve the outcomes of patients with relapsed and refractory immune thrombocytopenia patients and they were well tolerated, its mechanism may be related with the balance between T cell sunsets and Treg cells.

BACKGROUND/AIMS: The relationship between patient survival and biopsy-proven acute rejection (BPAR) in liver transplant recipients with hepatitis C remains unclear. The aims of this study were to compare the characteristics of patients with and without BPAR and to identify risk factors for BPAR. METHODS: We retrospectively reviewed the records of 169 HCV-RNA-positive patients who underwent LT at three centers. RESULTS: BPAR occurred in 39 (23.1%) of the HCV-RNA-positive recipients after LT. The 1-, 3-, and 5-year survival rates were 92.1%, 90.3%, and 88.5%, respectively, in patients without BPAR, and 75.7%, 63.4%, and 58.9% in patients with BPAR (P<0.001). Multivariate analyses showed that BPAR was associated with the non-use of basiliximab and tacrolimus and the use of cyclosporin in LT recipients with HCV RNA-positive. CONCLUSION: The results of the present study suggest that the immunosuppression status of HCV-RNA-positive LT recipients should be carefully determined in order to prevent BPAR and to improve patient survival.

Ulcerative colitis is a chronic inflammatory condition of the colon, characterized by diffuse mucosal inflammation and blood-mixed diarrhea. The main treatment has been 5-aminosalicylic acid, steroid, thiopurine, and anti-tumor necrosis factor alpha (TNF-alpha) antibodies including infliximab, adalimumab, and golimumab. Golimumab, a new anti-TNF-alpha agent has been recently approved for patients with moderate to severe ulcerative colitis. Its efficacy and safety has been demonstrated in line with infliximab and adalimumab in preclinical and clinical studies. This review will focus on golimumab therapy in ulcerative colitis.

OBJECTIVETo investigate the influence of divalent cation chelator EDTA and heparin sodium on the detection of ITP platelet-specific autoantibodies by the modified monoclonal antibody immobilization of platelet antigen assay (MAIPA) and to explore the relationship between types of platelet specific autoantibodies and glucocorticoid efficacy.

METHODSThe samples were obtained from EDTA- and heparin- anticoagulant ITP patients, respectively, so as to detect the platelet-specific autoantibodies (GPIIb/IIIa and GPIbα) in 140 ITP samples by modified MAIPA, then the differences between these two methods were compared.

RESULTSOut of 140 cases in EDTA group, 55 cases were positive for GPIIb/IIIa, while 76 cases in heparin group were positive for GPIIb/IIIa, 42 cases in both group were repeatable; among them 13 cases were positive in EDTA group and negative in heparin group, while 34 cases were positive in heparin group and negative in EDTA group, there was significant difference between them (x (2) = 9.38, P < 0.05), 62 cases in 140 cases of EDTA group were positive for GPIba, while 51 cases in heparin group were positive for GPIba, 42 cases in both group were repeatabe; among them 20 cases were positive in EDTA group and negative in heparin group, while 9 cases were positive in heparin group and negative in EDTA group, there was no significant difference between them (x (2) = 3.44, P > 0.05). A total of 320 cases received a standard glucocorticoid treatment, out of them 143 cases were positive for GPIbα with effective rate 39.9%, 177 cases were negative for GPIbα with effective rate 79.7%, there was statisticalty significant difference between them (x (2) = 53.115, P < 0.05).

CONCLUSIONEDTA anticoagulant (a divalent cation chelator) has a significant influence on detection of ITP platelet-specific autoantibodies (GPIIb/IIIa) by a modified MAIPA method and the GPIbα antibody positive may be one of the important factors that results in un-sensitivity of ITP patients to glucocorticoid treatment.

BACKGROUND/AIMS: Several studies have demonstrated the effect of autologous hematopoietic stem cell transplantation (auto-HSCT) as a salvage treatment for patients with relapsed diffuse large B-cell lymphoma (DLBCL). However, the role of auto-HSCT as a frontline treatment has not been fully investigated in the rituximab era. We validated the age-adjusted International Prognostic Index (aaIPI) score for high-risk DLBCL patients and identified a possible role for frontline auto-HSCT. METHODS: We recommended frontline auto-HSCT for high-risk DLBCL patients who satisfied the criteria of both a higher Ann-Arbor stage (III to IV) and an elevated lactate dehydrogenase (LDH) level at diagnosis with an aaIPI score > or = 2. From 2006 to 2011, among the 150 DLBCL patients aged < or = 60 years who were treated with six cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP), 23 high-risk patients with a complete response (CR) were treated with auto-HSCT. For comparison, we selected 35 well-matched high-risk patients with CR who completed R-CHOP treatment alone. In addition, there were 81 low-risk patients and 11 refractory patients. RESULTS: DLBCL patients with an aaIPI score > or = 2 showed inferior overall survival (OS; p = 0.040) and progression-free survival (PFS; p = 0.007) compared to the aaIPI score 0 to 1. Between the two treatment arms among the high-risk DLBCL patients, the clinical parameters were not different. The high-risk group treated with frontline auto-HSCT showed similar OS (p = 0.392) and PFS (p = 0.670) to those in the low-risk group. Thus, frontline auto-HSCT showed superior PFS (p = 0.004), but only a trend towards favorable OS (p = 0.091) compared to R-CHOP alone. CONCLUSIONS: We identified the possible role of frontline auto-HSCT for high-risk DLBCL with a higher stage (III to IV) and elevated LDH level.

Several studies have suggested that a positive lymphocyte cross-matching (XM) is associated with low graft survival rates and a high prevalence of acute rejection after adult living donor liver transplantations (ALDLTs) using a small-for-size graft. However, there is still no consensus on preoperative desensitization. We adopted the desensitization protocol from ABO-incompatible LDLT. We performed desensitization for the selected patients according to the degree of T lymphocyte cross-match titer, model for end-stage liver disease (MELD) score, and graft liver volume. We retrospectively evaluated 230 consecutive ALDLT recipients for 5 yr. Eleven recipients (4.8%) showed a positive XM. Among them, five patients with the high titer (> 1:16) by antihuman globulin-augmented method (T-AHG) and one with a low titer but a high MELD score of 36 were selected for desensitization: rituximab injection and plasmapheresis before the transplantation. There were no major side effects of desensitization. Four of the patients showed successful depletion of the T-AHG titer. There was no mortality and hyperacute rejection in lymphocyte XM-positive patients, showing no significant difference in survival outcome between two groups (P=1.000). In conclusion, this desensitization protocol for the selected recipients considering the degree of T lymphocyte cross-match titer, MELD score, and graft liver volume is feasible and safe.

PURPOSE: The modified Glasgow Prognostic Score (mGPS) consisting of serum C-reactive protein and albumin levels, shows significant prognostic value in several types of tumors. We evaluated the prognostic significance of mGPS in 285 patients with diffuse large B cell lymphoma (DLBCL), retrospectively. MATERIALS AND METHODS: According to mGPS classification, 204 patients (71.5%) had an mGPS of 0, 57 (20%) had an mGPS of 1, and 24 (8.5%) had an mGPS of 2. RESULTS: Our study found that high mGPS were associated with poor prognostic factors including older age, extranodal involvement, advanced disease stage, unfavorable International Prognostic Index scores, and the presence of B symptoms. The complete response (CR) rate after 3 cycles of R-CHOP chemotherapy was higher in patients with mGPS of 0 (53.8%) compared to those with mGPS of 1 (33.3%) or 2 (25.0%) (p=0.001). Patients with mGPS of 0 had significantly better overall survival (OS) than those with mGPS=1 and those with mGPS=2 (p=0.036). Multivariate analyses revealed that the GPS score was a prognostic factor for the CR rate of 3 cycle R-CHOP therapy (p=0.044) as well as OS (p=0.037). CONCLUSION: mGPS can be considered a potential prognostic factor that may predict early responses to R-CHOP therapy in DLBCL patients.

BACKGROUNDBone damage around the joints is one of the major pathophysiological mechanisms that leads to rheumatoid arthritis (RA) chronic disability. Serum tartrate-resistant acid phosphatase 5b (TRACP-5b) is secreted by osteoclasts, its activity can be used as a clinically relevant bone resorption marker. The aim of this study was to test whether the measurement of serum levels of TRACP-5b in patients with RA would correlate with measures of disease activity and with responses to therapy.

METHODSFifty-six patients were randomly assigned to receive recombinant human cytotoxic tlymphocyte-associated antigen-4 immunoglobulin (RhCTLA4-Ig), infliximab or methotrexate (MTX). The clinical and serologic indicators of RA activity were evaluated at baseline and at 24 weeks. Serum TRACP-5b was measured by Enzyme-linked Immunosorbent Assay (ELISA) at 0, 12 and 24 weeks. Hand X-rays were obtained at baseline.

RESULTSAt baseline, the levels of TRACP-5b correlated with the severity of X-ray damage, disease duration (r = 0.332, P = 0.012), and tender joint count (r = 0.408, P = 0.002). The 24 weeks values of TRACP-5b for RhCTLA4-Ig group and infliximab group differed significantly from the baseline values in each group (P < 0.05; P < 0.05), whereas only the value for RhCTLA4-Ig group differed significantly from the 24 weeks value for the MTX group (P < 0.01). Considering the two biologics-treated groups together, the TRACP-5b levels at 24 weeks differed significantly from the baseline values only in those patients who reached an ACR70 level (P < 0.05).

CONCLUSIONSMeasurement of serum TRACP-5b in RA patients reflects clinical and radiological measures of disease activity, treatment with certain biologics, and degree of response to therapy. TRACP-5b should be investigated further as a potential biomarker to predict response to therapy, including slowing of radiographic progression.
