Usefulness of abdominal ultrasonography in the analysis of endoscopic activity in patients with Crohn's disease: changes following treatment with imm…
2013
The objective of this study was to analyze the accuracy of abdominal ultrasonography (AUS) in the assessment of mucosal healing in patients with Crohn's disease (CD) receiving immunomodulators and/or biological treatment, with ileocolonoscopy as the reference standard.Thirty patients were included in a prospective longitudinal study. All patients underwent ileocolonoscopy and AUS before and after a minimum of one year of treatment. The Crohn's Disease Endoscopic Inflammatory Index of Severity (CDEIS) was used for endoscopic assessment whereas AUS was analyzed by means of bowel wall thickness, color Doppler grade and percentage of increase of parietal enhancement after contrast injection.In …
Thymosin α1 and α-Inteferon with Cisplatin and Etoposide in Advanced Non-Small-Cell Lung Cancer: A Phase II Study
1993
In recent years, biological response modifiers (BRMs) have emerged as an important new class of agents for treating cancer. Agents such as interferon (IFN) and interleukin 2 (IL-2) have been reported to induce significant tumor regression in various types of cancer usually resistant to chemotherapy (1,12), but their use in non-small-cell lung cancer (NSCLC) has received little attention.
P228 Cytomegalovirus Infection: is it a cause of flare-up in inflammatory bowel diseases?
2020
Abstract Background The presence of CMV in blood is quite common in patients with severe flares of ulcerative colitis (UC) and Crohn’s disease (CD) and seems to predict an adverse outcome. The impact of antiviral treatment on CMV in this setting (indications and drug options) is an unresolved issue. Our aim was to reassess the CMV role in patients with IBD hospitalised for severe exacerbations, analysing the relationship between CMV positivity, clinical characteristics, antiviral therapy and disease outcomes. Methods We evaluated a homogeneous cohort of 97 consecutive patients with IBD hospitalised from 2012 to 2018. Data regarding age, gender, smoke, familial predisposition, type of IBD, e…
Cytokines with Possible Clinical Utility
1987
Biological response modifiers (BRM) are agents aimed at reducing tumor growth, not primarily by exerting direct cytotoxic effects but by modulation of tumor gene expression (e.g., induction of differentiation) or by enhancing host defense mechanisms directed against cancer cells. BRM as primary therapy or as adjuncts to cytotoxic agents in the treatment of cancers have attracted increasing interest in view of stagnating clinical results in many areas [1], and there is increasing evidence of in vitro and in vivo efficacy of these agents. Furthermore, advances in molecular biology suggesting that oncogenes and their products play a crucial role in oncogenesis support approaches to modulation …
Therapy of Peritoneal Murine Cancer with Biological Response Modifiers
1985
We have used a murine renal adenocarcinoma of spontaneous origin (Renca) inplanted in the peritoneal cavity to study the therapeutic potential of biological response modifiers (BRMs) used alone or in conjunction with chemotherapy. This tumor model is therapeutically challenging since following intraperitoneal (i.p.) injection, the tumor grows progressively with hemorrhagic ascites, abdominal metastases to lymph nodes, liver, spleen, most serous membranes, and, in some animals, metastases to extra-abdominal sites (lungs). In the absence of therapy, death invariably occurs within 36 +/- 2 days. The tumor is efficiently lysed in 4 hours by peritoneal cells isolated from mice treated with BRMs.…
