Organizing Pneumonia in A Patient Double-Positive for ANCA and Anti-GBM Antibodies: A Case Report / 中国医学科学杂志(英文版)

Both anti-glomerular basement membrane (GBM) disease and the anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) are common causes of pulmonary-renal syndrome. Organizing pneumonia (OP), a special pattern of interstitial lung disease, is extremely rare either in AAV or anti-GBM disease. We report an old woman presented with OP on a background of co-presentation with both ANCA and anti-GBM antibodies.

Role of YKL-40 in the Microenvironment of Glioblastoma / 中国生物化学与分子生物学报

Glioblastoma (GBM) is the most common malignant tumor of the brain and central nervous system. The complex tumor microenvironment of glioblastoma is considered as the main challenge for clinical treatment of glioblastoma, also the main reason for the high recurrence rate and low survival rate of glioblastoma patients. YKL-40, a secreted protein, is associated with poor prognosis in many types of solid tumors. The expression of YKL-40 in serum and tumor tissues is significantly increased in high-grade gliomas, especially in glioblastoma patients. While this feature is not found in low-grade gliomas, indicating that the expression of YKL-40 is closely related to glioma grade and malignant development. Targeted therapy using YKL-40 antibody together with ionizing radiation has also been shown to synergistically inhibit tumor angiogenesis and malignant progression in glioblastoma patients. Based on the important role of YKL-40 in regulating the tumor microenvironment, this paper summarizes the research progress of YKL-40 in malignant tumors, and discusses the related role of YKL-40 in the occurrence and development of glioblastoma and its clinical application prospect.

Reporte de un caso de glomerulonefritis rápidamente progresiva por anticuerpos antimembrana basal glomerular / Case report of rapidly progressive glomerulonephritis due to anti-glomerular basement membrane antibodies

RESUMEN Una vez más en medicina interna no podemos, aún, prescindir de los métodos invasivos para alcanzar un diagnóstico. Los avances diarios en el hallazgo de nuevas herramientas paraclínicas no permiten reemplazar aquellos métodos de certeza como la anatomía patológica. El caso presentado es una muestra de ello. Se trata de una mujer de 27 años de edad, con antecedente de tiroiditis de Hashimoto que consulta por presentar severo deterioro de la función renal asociado a oligoanuria. Realizamos una revisión del tratamiento de las glomerulonefritis rápidamente progresivas por anticuerpos antimembrana basal glomerular, serológicamente negativas.

ABSTRACT Once again in internal medicine we cannot do a diagnosis without invasive methods. Daily advances in the finding of new paraclinical tools do not allow the replacement of certain methods such as pathological anatomy. The case presented is a sample of this. This is a 27-year-old woman with a history of Hashimoto's thyroiditis who consults for presenting severe impairment of kidney function associated with oligoanuria. We performed a review of the treatment of the rapidly progressive glomerulonephritis for serologically negative anti-GBM antibodies.

National trends in radiation dose escalation for glioblastoma

PURPOSE: Glioblastoma (GBM) carries a high propensity for in-field failure despite trimodality management. Past studies have failed to show outcome improvements with dose-escalation. Herein, we examined trends and outcomes associated with dose-escalation for GBM. MATERIALS AND METHODS: The National Cancer Database was queried for GBM patients who underwent surgical resection and external-beam radiation with chemotherapy. Patients were excluded if doses were less than 59.4 Gy; dose-escalation referred to doses ≥66 Gy. Odds ratios identified predictors of dose-escalation. Univariable and multivariable Cox regressions determined potential predictors of overall survival (OS). Propensity-adjusted multivariable analysis better accounted for indication biases. RESULTS: Of 33,991 patients, 1,223 patients received dose-escalation. Median dose in the escalation group was 70 Gy (range, 66 to 89.4 Gy). The use of dose-escalation decreased from 8% in 2004 to 2% in 2014. Predictors of escalated dose were African American race, lower comorbidity score, treatment at community centers, decreased income, and more remote treatment year. Median OS was 16.2 months and 15.8 months for the standard and dose-escalated cohorts, respectively (p = 0.35). On multivariable analysis, age >60 years, higher comorbidity score, treatment at community centers, decreased education, lower income, government insurance, Caucasian race, male gender, and more remote year of treatment predicted for worse OS. On propensity-adjusted multivariable analysis, age >60 years, distance from center >12 miles, decreased education, government insurance, and male gender predicted for worse outcome. CONCLUSION: Dose-escalated radiotherapy for GBM has decreased over time across the United States, in concordance with guidelines and the available evidence. Similarly, this large study did not discern survival improvements with dose-escalation.

Predictive factors for survival and outcome in patients with high grade gliomas: A single centre retrospective study

Background: Patients with high grade gliomas have poor survival even with aggressive multimodality approach. The aim of our study is to evaluate the predicting factors affecting the survival outcome in patients with high grade gliomas (HGG). Materials and methods: 46 patients diagnosed to have high grade gliomas (HGG) treated in our Radiotherapy department during the period of March 2014 to March 2017 were analyzed in this single centre retrospective study. All patients underwent maximal safe surgery followed by postoperative radiotherapy with or without temozolamide chemotherapy. Data regarding the patient age, gender, performance status, histology, grade of the tumor, tumor location, extent of surgery, radiotherapy, and chemotherapy details were collected and analyzed. The differences in clinical characteristics and treatment variables were analyzed by chi square test and overall survival analysis using Kaplan Mayer method. The Cox proportional hazards regression model was used to determine statistically significant variables related to survival. Results: The median survival of patients with HGG in this study was 9 months. The median survival of patients with grade III and IV glioma was 19 and 4 months respectively. In univariate analysis histology, grade, laterality were identified to have prognostic significance. The result of multivariate analysis showed that performance status, grade, histology, extent of surgery is significant for survival. S. Jeeva, V. Vanitha, K. Chandralekha, M.

The survival of HGG was poor in spite of combined modality treatment.

Research progress of epithelial-to-mesenchymal(-like) transition in glioblastoma / 中国肿瘤临床

Epithelial-to-mesenchymal transition (EMT) is a normal process of cell physiological development in which the epithelial cells transform into mesenchymal cells through a specific program. EMT plays key roles in embryogenesis, tissue regeneration, and tu-mor progression. Recent research has shown the involvement of EMT-like in the tumorigenesis and progression (especially invasion and metastasis) of glioblastoma (GBM). This article reviews the molecular regulatory mechanisms of EMT (-like) including the main sig-naling pathways, EMT-factors, miRNA, cancer stem cells, hypoxia microenvironments, and therapy resistance in GBM.

Regulatory effect of hsa-miR-150-5p on malignant behaviors of glioblastoma U-251MG cells by targeting HIF1α / 中国肿瘤生物治疗杂志

@#Objective: To explore the effect and possible mechanisms of has-miR-150-5p targeting HIF1α to regulate malignant biological behaviors of glioblastoma (GBM) U-251MG cells. Methods: Real-time quantitative PCR (RT-PCR) was used to detect the expression of miR-150-5p and hypoxia inducible factor 1 (HIF1α) in U-251MG cells. Luciferase report assay was carried out to verify the biological relationship between miR-150-5p and HIF1α and their biological functions in U-251MG cells. The protein expressions of miR150-5pand HIF1α in U-251MG cells were detected by western blotting. The ability of cell migration was detected by wound healing test and cell invasion ability was detected by transwell test. Results: After miR-150-5p mimic transfection, the mRNA expression of HIF1α was significantly reduced in U-251MG cells (P<0.01). Bioinformatics prediction and luciferase reporter assay demonstrated that miR-150-5p down-regulated HIF1α through directly binding to HIF1α 3’-untranslated region (3’-UTR) (all P<0.05). In U-251MG cells, miR-150-5p over-expression significantly inhibited HIF1α expression, cell invasion and migration (all P<0.05). Conclusion: miR150-5p inhibits cell invasion and metastasis through negative regulation of HIF1α, indicating that miR-150-5p and HIF1α were both potential therapeutic targets for glioblastoma.

Síndrome de Goodpasture atípico como reto diagnóstico / Atypical Goodpasture syndrome as diagnostic challenge

Resumen La enfermedad de Goodpasture es una entidad clínica con una base fisiopatológica inmunológica como punto de partida, en la que la unión al dominio terminal NC1 afecta principalmente en la zona glomerular y pulmonar, con lo que su diagnóstico está orientado hacia estas insuficiencias orgánicas; su incidencia varía de 0.5 a 1 casos por millón de habitantes, por lo que se considera una enfermedad poco frecuente y de mortalidad elevada debido a las complicaciones derivadas del mecanismo inmunológico. La manifestación pulmonar de manera aislada representa un porcentaje aún menor; la hemoptisis es, incluso en 66% de los casos, la forma más frecuente de expresión clínica. El pronóstico de estos pacientes se asocia con la forma de manifestación de la enfermedad y la calidad en la atención recibida. El diagnóstico definitivo se realiza mediante toma de biopsia; sin embargo, la existencia de anticuerpos anti-MBG (antimembrana basal glomerular) mediante la prueba ELISA puede manejarse en el diagnóstico con buena sensibilidad.

Abstract Goodpasture's disease is a clinical entity with an immunological pathophysiological basis, where the union to terminal NC1 domain mainly affects glomerular and lungs; thus, its diagnosis is oriented to such organ failure; its incidence varies from 0.5 to 1 cases per million population, for this reason it is considered a rare disease with high mortality due to complications from immune mechanism. Isolated lung presentation accounts for an even fewer percentage; in two thirds of cases hemoptysis is the most common clinical expression of the disease. Prognosis of these patients is associated to the presentation of the disease and the quality of care provided during the same. The definitive diagnosis is made by biopsy; however, the presence of antiGBM antibodies (glomerular basement membrane) by ELISA can be handled in the diagnosis with good sensitivity.

GBM Propensity Score Weighting for Causal Inference Research / 世界科学技术-中医药现代化

Objective In observational studies or non-randomized design,the researchers' ability to make causal inferences from data was hampered by confounding factors.This study used this method to analyze a group of observational medical data in order to instruct relevant medical personnel to carry out their own causal inference studies.Methods At present,the four main types of propensity scoring methods:matching,stratification,inverse probability weighting and covariate adjustment have been widely used in the study of causal inference.Propensity score method can theoretically eliminate the bias of the observable confounding factors,so that the treatments variables are close to the result of random assignment design,thus,it is estimated that the treatment factor has a causal effect on the outcome.Results Considering the advantages of the inverse probability weighting method over other methods,this paper summarizes the applicable conditions for the estimate of causal effect,particularly illustrates the use of a modern nonparametric statistical technology--Generalized Boosted Models (GBM) and its advantages and disadvantages.Conclusion When there is a lot of different types of confounding factors,and uncertain functional forms for their associations with treatment selection in linear,non-linear or interaction effect,and other issues,GBM propensity score weighting method can overcome the obstacles in the process of accurately estimating propensity score.

Differentiation between Glioblastoma and Primary Central Nervous System Lymphoma Using Dynamic Susceptibility Contrast-Enhanced Perfusion MR Imaging: Comparison Study of the Manual versus Semiautomatic Segmentation Method

BACKGROUND: Normalized cerebral blood volume (nCBV) can be measured using manual or semiautomatic segmentation method. However, the difference in diagnostic performance on brain tumor differentiation between differently measured nCBV has not been evaluated. PURPOSE: To compare the diagnostic performance of manually obtained nCBV to that of semiautomatically obtained nCBV on glioblastoma (GBM) and primary central nervous system lymphoma (PCNSL) differentiation. MATERIALS AND METHODS: Histopathologically confirmed forty GBM and eleven PCNSL patients underwent 3T MR imaging with dynamic susceptibility contrast-enhanced perfusion MR imaging before any treatment or biopsy. Based on the contrast-enhanced T1-weighted imaging, the mean nCBV (mCBV) was measured using the manual method (manual mCBV), random regions of interest (ROIs) placement by the observer, or the semiautomatic segmentation method (semiautomatic mCBV). The volume of enhancing portion of the tumor was also measured during semiautomatic segmentation process. T-test, ROC curve analysis, Fisher's exact test and multivariate regression analysis were performed to compare the value and evaluate the diagnostic performance of each parameter. RESULTS: GBM showed a higher enhancing volume (P = 0.0307), a higher manual mCBV (P = 0.018) and a higher semiautomatic mCBV (P = 0.0111) than that of the PCNSL. Semiautomatic mCBV had the highest value (0.815) for the area under the curve (AUC), however, the AUCs of the three parameters were not significantly different from each other. The semiautomatic mCBV was the best independent predictor for the GBM and PCNSL differential diagnosis according to the stepwise multiple regression analysis. CONCLUSION: We found that the semiautomatic mCBV could be a better predictor than the manual mCBV for the GBM and PCNSL differentiation. We believe that the semiautomatic segmentation method can contribute to the advancement of perfusion based brain tumor evaluation.

Serum microRNA profiles as novel biomarkers for the post-operative evaluation and survival of patients with glioblastoma multiform / 中国肿瘤临床

Objective:To investigate the differentially expressed miRNAs in serum collected post operation and compared these miR-NAs with those collected pre-surgery among patients suffering from glioblastoma multiform (GBM) and undergoing regular clinical fol-low-up. These miRNAs may be potential biomarkers for the post-operative evaluation of patients with GBM. Methods:Forty-eight pa-tients with GBM and clinical pathological diagnosis were enrolled in this study. In the initial biomarker screening stage, total RNAs were extracted and subjected to Solexa sequencing to select miRNAs with significantly altered expression pre-and post-operation. Some of these differentially expressed miRNAs were chosen and verified through TaqMan probe-based qRT-PCR assay. A t-test was performed to determine the miRNAs that satisfied the two criteria, namely, fold change>2 and P<0.05. All of the patients were fol-lowed-up, and survival data were collected. The patients were then classified into two groups, namely, long-and short-survival groups, on the basis of the median of the miR-30e expression levels in the sera collected post-operation. Kaplan-Meier method and Log-rank test (SPSS version 19.0, IBM) were employed to determine the possible relationships between miR-30e expression levels in the sera collected post-operation and patients' overall survival. Results: Solexa revealed 63 differentially expressed miRNAs. Four miRNAs, namely, miR-26b, miR-30e, miR-129-3p, and miR-206, were selected on the basis of previous and present findings. These miRNAs were then verified in the RT-qPCR phase. Among these miRNAs, only miR-30e was significantly upregulated post-operation. The serum miR-30e expression level post-operation was not significantly associated with the overall survival of the patients. A low miR-30e expression level corresponded to prolonged survival. Conclusion:miR-30e was upregulated in the sera collected post-operation from patients with GBM. This miRNA may be negatively related to the tumor load of these patients. The miR-30e expression level in the serum col-lected post-surgery serum was not significantly associated with overall survival. Therefore, miR-30e may serve as a novel potential non-invasive biomarker for the post-operative evaluation of patients with GBM.

L-carnitine sensitizes human glioblastoma cells to TRAIL-induced apoptosis / 中国药理学通报

Aim To investigate the enhancing effect of L-carnitine as a sensitizer on tumor necrosis factor-re-lated apoptosis inducing ligand ( TRAIL)-induced ap-optosis in glioma cells. Methods Glioma cell U87 was used as model cell line. Cell viability was determined by CCK-8 , and apoptosis was assessed by Annexin V-FITC/PI staining, caspase-3 activity and expres-sion. The expression and transcription of nuclear factor kappa B ( NF-κB ) and FLICE inhibiting protein ( c-FLIP) were measured by RT-PCR and Western blot. In addition, NF-κB was knockdown to analyze its regu-lating effect on c-FLIP expression. Results The com-bination treatment with TRAIL and L-carnitine signifi-cantly inhibited cell proliferation and induced apopto-sis. Compared with control, combinational treatment significantly suppressed the transcription and expres-sion of c-FLIP as well as translocation of NF-κB. Through silencing NF-κB, NF-κB was found to act as upstream signaling to regulate c-FLIP. Conclusion L-carnitine sensitizes TRAIL-induced tumor cell apoptosis via suppression of NF-κB-dependent c-FLIP expres-sion.

Glioblastoma Multiforme Metastasizing to Humerus and Craniospinal Axis.

Glioblastoma multiforme (GBM) is the most common malignant brain tumour. GBM metastasizing to humerus has never been reported. This is the first such case of recurrent GBM to be reported in medical literature with both extracranial and cerebrospinal dissemination. Our case amply demonstrated the need to keep vigil and high index of suspicion while interpreting the clinical and radiological findings in GBM wih a risk of CSF spread and systemic metastases.

Proliferating cell nuclear antigen, p53 and micro vessel density: Grade II vs. Grade III astrocytoma.

Histological classification and grading are prime procedures in the management of patients with astrocytoma, providing vital data for therapeutic decision making and prognostication. However, it has limitations in assessing biological tumor behavior. This can be overcome by using newer immunohistochemical techniques. This study was carried out to compare proliferative indices using proliferating cell nuclear antigen (PCNA), extent of p53 expression and micro vessel morphometric parameters in patients with low grade and anaplastic astrocytoma. Twenty-five patients, each of grade II and grade III astrocytoma were evaluated using monoclonal antibodies to PCNA, p53 protein and factor VIII related antigen. PCNA, p53-labeling indices were calculated along with micro vessel morphometric analysis using Biovis Image plus Software. Patients with grade III astrocytoma had higher PCNA and p53 labeling indices as compared with grade II astrocytoma (29.14 plus/minus 9.87% vs. 16.84 plus/minus 6.57%, p 0.001; 18.18 plus/minus 6.14% vs. 6.14 plus/minus 7.23%, p 0.001, respectively). Micro vessel percentage area of patients with grade III astrocytoma was also (4.26 plus/minus 3.70 vs. 1.05 plus/minus 0.56, p 0.001), higher along with other micro vessel morphometric parameters. Discordance between histology and one or more IHC parameters was seen in 5/25 (20%) of patients with grade III astrocytoma and 9/25 (36%) of patients with grade II disease. PCNA and p53 labeling indices were positively correlated with Pearson's correlation, p less than 0.001 for both). Increased proliferative fraction, genetic alterations and neovascularization mark biological aggressiveness in astrocytoma. Immunohistochemical evaluation scores over meet the challenge of accurate prognostication of this potentially fatal malignancy.

Brain Tumor Stem Cells as Therapeutic Targets in Models of Glioma

At this time, brain tumor stem cells remain a controversial hypothesis while malignant brain tumors continue to present a dire prognosis of severe morbidity and mortality. Yet, brain tumor stem cells may represent an essential cellular target for glioma therapy as they are postulated to be the tumorigenic cells responsible for recurrence. Targeting oncogenic pathways that are essential to the survival and growth of brain tumor stem cells represents a promising area for developing therapeutics. However, due to the multiple oncogenic pathways involved in glioma, it is necessary to determine which pathways are the essential targets for therapy. Furthermore, research still needs to comprehend the morphogenic processes of cell populations involved in tumor formation. Here, we review research and discuss perspectives on models of glioma in order to delineate the current issues in defining brain tumor stem cells as therapeutic targets in models of glioma.

Glioblastoma multiforme: a rare manifestation of extensive liver and bone metastases

Glioblastoma multiforme (GBM) is the most aggressive form of primary brain tumours known collectively as gliomas. Gliomas are graded by their microscopic appearance. As a rule, their behaviour can be predicted from histology: Grade I (pilocytic astrocytomas) and Grade II (benign astrocytomas) tumours are of low grade and grow slowly over many years. Grade IV tumours (GBM) are the most aggressive and, unfortunately, also the most common in humans, growing rapidly, invading and altering brain function. These tumours arise from the supporting glial cells of the brain during childhood and in adulthood. These growths do not spread throughout the body like other forms of cancer, but cause symptoms by invading the brain. Untreated GBMs are rapidly lethal. Most patients with GBM die of their disease in less than a year and none have long term survival. Extracranial metastases from GBM are extremely rare, with a reported frequency of only 0.44% because of the absence of lymphatics in the brain and the difficulty of tumours to penetrate blood vessels. A case of glioblastoma multiforme with the rare features of extensive liver and bone metastases is presented in this paper.

A Case of Goodpasture's Syndrome Combined with Crohn's Disease / 결핵및호흡기질환

A 29-year-old male patient was admitted due to his general weakness and poor oral intake for several months. He was diagnosed as having Crohn disease 16 years ago and total colectomy was performed 10 years ago. On the 3rd day after admission, gross hematuria and sudden hemoptysis combined with diffuse infiltration were noted on chest X-ray. His symptoms and the diffusely increased lung opacities improved with administering high-dose steroid therapy. Later, anti-GBM antibody was found to be positive on the laboratory findings. We report here on a rare case of Goodpsture syndrome combined with prolonged Crohn disease along with a review of literature.

Adenovirus-mediated Gene Therapy of Uteroglobin Protects the Experimental Glomerulonephritis in Mice / 대한신장학회잡지

PURPOSE: Uteroglobin (UG), steroid inducible cytokine-like protein, has potent anti-inflammatory and immunomodulatory action. It is secreted by the mucosal epithelia of virtually all mammals. The aims of this study were to investigate the efficacy of recombinant adenovirus carrying uteroglobin (AdCMV-UG) in prevention and treatment of glomerulonephritis (GN) in mice. METHODS: The AdCMV-UG was created by inserting the uteroglobin cDNA into the pAdTrack- CMV vector and was transfected into the 293 cells through liposome mediated vehicles. AdCMV-UG was injected direct to the both kidneys of 20 mice. In control groups (disease controls), 13 mice received adenoviral vector with GFP and another 11 mice received PBS only. After 5days of viral injection, GN was induced by repetitive intravenous injection of 3.0 mg rabbit anti-GBM Ab to the pretreated mice (C57/B6). Histological and biochemical changes were evaluated 7 and 14 days after injection of anti-GBM Ab. RESULTS: UG was expressed in the renal tissues and mesangial cells infected with the infection of AdCMV-UG. Pretreatment with AdCMV-UG attenuated the cellular crescent formation 7 days after induction of GN when compared to AdCMV-GFP, PBS only. We also observed reduced mesangial matrix expansion in mice treated with adenovirus carrying UG. Proteinuria was significantly reduced in the mice treated with adenovirus carrying UG when compared with disease control mice (AdCMV-UG 102.2+/-20.97, AdCMV-GFP 170.6+/-41.77, and PBS 169.8+/-55.67, respectively p<0.05 mg/mg). However, at 14 days after anti-GBM Ab injection (total 19 days), there was no significant difference in the amounts of prot einuria and morphologic findings between pretreated and disease control groups. CONCLUSION: Adenoviral mediated gene transfer is an effective way of gene delivery. Locally expressed uteroglobin attenuated the severity of glomerulonephritis induced by anti-GBM antibody, although it was transient. Gene therapy using uteroglobin may be constituted for the treatment of human diseases such as chronic GN.

Prevention and Treatment of Experimental Glomerulonephritis Using Recombinant Uteroglobin / 대한신장학회잡지

Glomerulonephritis(GN) is characterized by cognate immune responses against self or non-self antigen. It is suggested that the crescentic GN is a manifestation of cell-mediated immune response akin to delayed type hypersensitivity. Uteroglobin(UG) is a steroid-dependent, immunomodulatory, and cytokine-like protein. It was reported that UG prevented fibronectin(Fn) deposition in the glomeruli of normal mice to form Fn-UG heterodimers that competed with Fn self-aggregation. We hypothesized that UG would prevent the development of experimental GN induced by anti-glomerular basement membrane globulin(anti-GBM Ab) in mice through immunomodulatory properties. GN was induced by intravenous injection of 4.5 mg rabbit anti-GBM Ab to mice(C57BL/6). Renal injury was evaluated at 7, 14, and 21 days thereafter. UG-treated mice(n=10) were received for 3 days(0.5 mg/mouse/day) beginning 1 hour after anti-GBM Ab injection. Also, disease-control mice(n=10) were received PBS for 3 days after anti-GBM Ab. Proteinuria was significantly reduced in the mice treated with UG when compared with the disease-control mice after 7 and 14 days of anti-GBM Ab injection. The amount of proteinuria was similar between UG treated and normal control mice. The mesangial matrix expansion and cellular crescent were markedly attenuated by the injection of UG. The proliferative responses of mesangial cells(C57BL/6) to LPS were blunted with the addition of UG in dose-dependent manner. In this study, we revealed the preventive effects of UG in the experimental model of glomerulonephritis. This result in turn could provide the basis for the treatment of human disease such as chronic glomerulonephritis.
