Objective: To analyze the value of 3-dimensional speckle tracking echocardiograghy (3D-STE) derived strain parameters on the detection of subclinical myocardial deformation alterations in patients with lymphoma treated with anthracycline agents. Methods: This study was a retrospective study. A total of 37 patients with newly diagnosed diffuse large B cell non-Hodgkin lymphoma between December 2012 and December 2014 in Cancer Center, Fudan university were included. 3D-STE strain measurements were performed at baseline (T0),after the completion of two therapy circles (T1) and at the end of anthracycline regimen chemotherapy (Te). Echocardiography images were analyzed on the TTA workstation, and the indexes included left atrial minimum volume (LAVmin), left atrial emptying index (LAEF), left atrial active emptying index (LAAEF), as well as the left ventricular global longitudinal strain (LVGLS), left ventricular global circumferential strain (LVGCS), left atrial global longitudinal strain (LAGLS). The overall left atrioventricular longitudinal strain (LAVGLS) was calculated, which was the sum of the absolute values of LVGLS and LAGLS. The changes of left ventricular strain indexes measured by 3D-STE at different time points of patients were evaluated. Results: Thirty-seven patients with DLBCL, aged (48.3±12.1)years, including 23 males (63.9%), were enrolled. Compared with baseline, LVGLS (T1: (-18.63±4.73)% vs. (-22.13±4.40)%, P=0.001; Te:(-18.26±4.64)% vs. (-22.13±4.40)%, P<0.001), LAGLS (T1: (20.41±5.56)% vs. (23.98±5.59)%, P=0.003; Te: (17.60±3.96)% vs. (23.98±5.59)%, P<0.001) and LAVGLS (T1: (39.05±7.60)% vs. (46.11±7.77)%, P<0.001; Te: (40.34±8.55)% vs. (46.11±7.77)%, P<0.001) were all deteriorated at the T1 and Te. While LVGCS ((-21.98±5.82)% vs. (-26.15±7.51)%, P=0.010), LAVmin ((23.93±7.29)ml vs. (20.33±7.03)ml, P=0.029), LAEF ((28.94±11.16)% vs. (35.79±11.12)%, P=0.002) and LAAEF ((11.93±10.00)% vs. (18.10±9.96)%, P=0.013) were decreased only until Te. Conclusions: 3D-STE strain measurements could detect early myocaridial function alteration in patients receiving anthracycline regimen chemotherapy, thus may provide a novel approach to monitor anthracycline caused myocardial toxicity.

As a new type of anthracyclines, pegylated liposomal doxorubicin (PLD) is widely used in the treatment of a variety of malignant tumors, including soft tissue sarcoma, ovarian cancer, breast cancer, multiple myeloma, and so on. Compared with traditional anthracyclines, PLD can significantly decrease the incidences of adverse events such as cardiac toxicity and alopecia. However, the use of PLD will be accompanied with toxic side effects such as hand-foot syndrome, oral mucositis, and infusion reaction. This consensus will mainly focus on the mechanism, prevention and treatment of adverse events of PLD, in order to improve the therapeutic efficacy of PLD and life quality of patients.

Background: Follistatin-like 1 (FSTL1) is a novel profibrogenic factor that induces pulmonary fibrosis (PF) through the transforming growth factor-beta 1 (TGF-β1)/Smad signaling. Little is known about its effects on PF through the non-Smad signaling, like the mitogen-activated protein kinase (MAPK) pathway. Therefore, this study aimed to investigate the role of FSTL1 in PF through the MAPK signaling pathway and its mechanisms in lung fibrogenesis. Methods: PF was induced in Fstl1and wild-type (WT) C57BL/6 mice with bleomycin. After 14 days, the mice were sacrificed, and lung tissues were stained with hematoxylin and eosin; the hydroxyproline content was measured to confirm PF. The mRNA and protein level of FSTL1 and the change of MAPK phosphorylation were measured by quantitative polymerase chain reaction and Western blotting. The effect of Fstl1 deficiency on fibroblasts differentiation was measured by Western blotting and cell immunofluorescence. MAPK signaling activation was measured by Western blotting in Fstl1 and WT fibroblasts treated with recombinant human FSTL1 protein. We pretreated mouse lung fibroblast cells with inhibitors of the extracellular signal-regulated kinase (ERK), p38, and Jun N-terminal kinase (JNK) signaling and analyzed their differentiation, proliferation, migration, and invasion by Western blotting, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide analysis, and transwell assays. The Student's t-test was used to compare the differences between two groups. Results: Fstl1 deficiency attenuated phosphorylation of the ERK, p38, and JNK signaling in bleomycin-induced fibrotic lung tissue 14 days after injury (0.67 ± 0.05 vs. 1.22 ± 0.03, t = 14.92, P = 0.0001; 0.41 ± 0.01 vs. 1.15 ± 0.07; t = 11.19; P = 0.0004; and 0.41 ± 0.01 vs. 1.07 ± 0.07, t = 8.92, P = 0.0009; respectively), compared with WT lungs at the same time and in primary lung fibroblasts (0.82 ± 0.01 vs. 1.01 ± 0.04, t = 4.06, P = 0.0150; 1.04 ± 0.03 vs. 1.24 ± 0.03, t = 4.44, P = 0.0100; and 0.76 ± 0.05 vs. 0.99 ± 0.05, t = 4.48, P = 0.0100; respectively), compared with TGF-β1-stimulated WT group. Recombinant human FSTL1 protein in lung fibroblasts enhanced TGF-β1-mediated phosphorylation of the ERK (1.19 ± 0.08 vs. 0.55 ± 0.04, t = 6.99, P = 0.0020), p38 (1.18 ± 0.04 vs. 0.66 ± 0.03, t = 11.20, P = 0.0020), and JNK (1.11 ± 0.01 vs. 0.84 ± 0.04, t = 6.53, P = 0.0030), compared with the TGF-β1-stimulated WT group. Fstl1-deficient fibroblasts showed reduced alpha-smooth muscle actin (α-SMA) expression (0.70 ± 0.06 vs. 1.28 ± 0.11, t = 4.65, P = 0.0035, compared with the untreated WT group; 1.40 ± 0.05 vs. 1.76 ± 0.02, t = 6.31, P = 0.0007; compared with the TGF-β1-treated WT group). Compared with the corresponding condition in the control group, the TGF-β1/FSTL1-mediated α-SMA expression was significantly suppressed by pretreatment with an inhibitor of p38 (0.73 ± 0.01 vs. 1.13 ± 0.10, t = 3.92, P = 0.0078) and JNK (0.78 ± 0.03 vs. 1.08 ± 0.06, t = 4.40, P = 0.0046) signaling. The proliferation of mouse lung fibroblast cells (MLgs) significantly decreased after treatment of an inhibitor of p38 (0.30 ± 0.01 vs. 0.46 ± 0.03, t = 4.64, P = 0.0009), JNK (0.30 ± 0.01 vs. 0.49 ± 0.01, t = 12.84, P = 0.0001), and Smad2/3 (0.18 ± 0.02 vs. 0.46 ± 0.02, t = 12.69, P = 0.0001) signaling compared with the dimethylsulfoxide group. The migration and invasion cells of MLgs significantly decreased in medium pretreated with an inhibitor of p38 (70.17 ± 3.28 vs. 116.30 ± 7.11, t = 5.89, P = 0.0042 for the migratory cells; 19.87 ± 0.84 vs. 32.70 ± 0.95, t = 10.14, P = 0.0005 for the invasive cells), JNK (72.30 ± 3.85 vs. 116.30 ± 7.11, t = 5.44, P = 0.0056 for the migratory cells; 18.03 ± 0.94 vs. 32.70 ± 0.95, t = 11.00, P = 0.0004 for the invasive cells), and Smad2/3 (64.76 ± 1.41 vs. 116.30 ± 7.11, t = 7.11, P = 0.0021 for the migratory cells; 18.03 ± 0.94 vs. 32.70 ± 0.95, t = 13.29, P = 0.0002 for the invasive cells) signaling compared with the corresponding condition in the dimethylsulfoxide group. Conclusion FSTL1 affects lung fibroblast differentiation, proliferation, migration, and invasion through p38 and JNK signaling, and in this way, it might influence the development of PF.

BACKGROUND/AIMS: To determine the incidence and clinical characteristics of tuberculosis (TB) medication-associated Clostridium difficile infection. METHODS: This multicenter study included patients from eight tertiary hospitals enrolled from 2008 to 2013. A retrospective analysis was conducted to identify the clinical features of C. difficile infection in patients who received TB medication. RESULTS: C. difficile infection developed in 54 of the 19,080 patients prescribed TB medication, representing a total incidence of infection of 2.83 cases per 1,000 adults. Fifty-one of the 54 patients (94.4%) were treated with rifampin. The patients were usually treated with oral metronidazole, which produced improvement in 47 of the 54 patients (87%). Twenty-three patients clinically improved with continuous rifampin therapy for C. difficile infection. There were no significant differences in improvement between patients treated continuously (n=21) and patients in whom treatment was discontinued (n=26). CONCLUSIONS: The incidence of C. difficile infection after TB medication was not low considering the relatively low TB medication dosage compared to other antibiotics. It may not be always necessary to discontinue TB medication. Instead, decisions concerning discontinuation of TB medication should be based on TB status.

Autoimmune hepatitis (AIH) is an immune-mediated chronic liver disease characterized by hepatocellular inflammation, necrosis, and fibrosis, which can progress to cirrhosis and fulminant hepatic failure. The standard treatment for AIH includes corticosteroids alone or in combination with azathioprine. Although most patients achieve remission using the standard regimen, some patients do not respond due to either drug intolerance or refractory disease; in such cases alternative immunosuppressive agents should be explored. The second-line therapies are cyclophilin inhibitors such as cyclosporine A or tacrolimus, and nowadays mycophenolate mofetil (MMF) is widely used if azathioprine-based therapies are not tolerated. Although these are recommended as an alternative to the first-line regimen, there is insufficient evidence for the efficacy of second-line therapies, with the evidence based mainly on expert opinion. Therefore, we report an AIH patient receiving the standard regimen in whom remission did not occur due to side effects to azathioprine, but was successfully treated with MMF in combination with corticosteroids as an alternative to the standard regimen.

OBJECTIVETo evaluate the efficacy and safety of cisplatin and capecitabine combination (XP) therapy for patients with metastatic triple negative breast cancer (TNBC) progressing after anthracycline and taxane treatment.

METHODSTwenty-nine metastatic TNBC patients were prospectively enrolled to receive capecitabine (1, 000 mg/m(2) twice daily on days 1-14) and cisplatin (75 mg/m(2) on day 1) , repeated every 3 weeks.

RESULTSWith a median of 6 cycles of XP, all 29 patients were evaluable for response, including 18 PR (62.1%), 6 SD (20.7%), 5 PD (17.2%) and no CR. The response rate was 62.1%. Patients with earlier stage at diagnosis (stage I to IIIA), longer post-operative disease free survival (>2 years) and less metastatic sites (≤ 3) obtained significantly higher response rate than patients with later stage at diagnosis (stage IIIB to IV), shorter post-operative disease free survival (≤ 2 years) and more metastatic sites (>3). The leading side effects were grade 1/2 gastrointestinal and hematological toxicities. Grade 3/4 toxicities included neutropenia (34.5%), leukocytopenia (31.0%), anemia (6.9%), thrombocytopenia (3.4%), nausea/vomiting (20.7%), stomatitis (3.4%), and hand-foot syndrome (3.4%).

CONCLUSIONCisplatin and capecitabine combination therapy is an active and well-tolerated doublet treatment in metastatic TNBC patients progressing after anthracycline and taxane treatments.

OBJECTIVETo assess the efficacy of vinorelbine (NVB)-based regimens in patients with metastatic triple negative breast cancer (mTNBC) pretreated with anthracyclines and taxanes.

METHODSClinical data of 48 patients diagnosed and treated for mTNBC between 2004 and 2012 at the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) were retrospectively analyzed. All patients were pretreated with anthracyclines and at least one taxane in neo-adjuvant, adjuvant or chemotherapy for mTNBC and patients should be having at least one measurable metastatic lesion. Totally, 48 patients were included in this study, of which 21 cases received first-line chemotherapy and 27 cases received second-line chemotherapy. Based on the regimen they received, 22 patients were treated with NVB plus platinum (NP), and 26 patients with NVB plus capecitabine (NX).

RESULTSAfter 70 months follow-up, in the total group of patients, the objective response rate was 20.8%, clinical benefit rate was 43.8%, median progression free survival (PFS) was 4.4 months and median overall survival (OS) was 15.5 months. In addition, the ORR was significantly better in the NP arm versus NX arm (33.8% vs.7.7%, P=0.029) as well as PFS was statistically improved in the NP arm than NX arm (5.3 m vs. 3.0 m, P=0.023). Similar trend was observed in the OS, although the difference was not statistically significant (27.7 m vs. 14.8 m, P=0.077). In all, the most frequently reported adverse events were G1/2 gastrointestinal toxicity (68.8%) and neutropenia (62.5%) . No significant difference was observed between the NP arm and NX arm (P>0.05). The percentage of patients who delayed chemotherapy administration in the NP arm and NX arm was 9.1% (n=2), and 3.8% (n=1), respectively.

CONCLUSIONSNVB-based combination chemotherapy demonstrates moderate efficacy in mTNBC patients pretreated with anthracyclines and one taxane with manageable toxicity. NP regimen shows potential superiority over NX regimen, and should be further verified in randomized phase III clinical trial in larger cohort.

There are several reports to demonstrate that rifampicin, a major anti-tuberculosis agent, is associated with some adverse renal effects, with a few cases of rifampicin-induced minimal change disease (MCD). In the present case, a 68-year-old female presented with nausea, vomiting, foamy urine, general weakness and edema. She had been taking rifampicin for 4 weeks due to pleural tuberculosis. The patient had no proteinuria before the anti-tuberculosis agents were started, but urine tests upon admission showed heavy proteinuria with a 24-h urinary protein of 9.2 g/day, and serum creatinine, albumin, and total cholesterol levels were 1.36 mg/dL, 2.40 g/dL, and 283 mg/dL, respectively. MCD was diagnosed, and the patient achieved complete remission after cessation of rifampicin without undergoing steroid therapy.

BACKGROUND/AIMS: Among diffuse large B cell lymphoma (DLBCL) patients, determining the appropriate dose and chemotherapy schedule to balance toxicity and efficacy is harder in elderly than in younger patients. Moreover, there are no currently available clinical factors that consistently identify patients who are unfit to receive chemotherapy. Therefore, the clinical characteristics and outcomes of elderly patients with DLBCL and the causes of treatment-related death were investigated in this study. METHODS: The clinical characteristics and outcomes of 44 elderly (> or = 70 years of age) patients diagnosed with DLBCL between January 2005 and June 2013 were evaluated. Variable clinical data along with the response rate, overall survival (OS), and causes of treatment-related death or treatment interruption were investigated. RESULTS: The median OS was 18.6 months, and 19 patients completed curative treatment. The mean average relative dose intensity of adriamycin in patients who completed chemotherapy was 0.617, and of these patients, 16 achieved complete remission. Chemotherapy incompletion, infectious complications, ex tranoda l involvement, high lactate dehydrogenase, poor performance status, and low albumin level at diagnosis were related to a shorter OS. However, multivariate analysis revealed that only infections and chemotherapy incompletion were significantly related to poor prognosis. The most common cause of treatment-related death was infection, and patients who had experienced infectious complications tended to have lower albumin levels than those of patients without such complications. CONCLUSIONS: In the treatment of elderly lymphoma patients, the dose intensity of adriamycin is not as important as it is in young patients. However, in elderly patients, infections are particularly dangerous, especially in patients with low albumin levels.
