Innovative Therapy, Monoclonal Antibodies and Beyond
2017
IF 6.794; International audience; The seventh Edition of "Innovative Therapy, Monoclonal Antibodies and Beyond" Meeting took place in Milan, Italy, on January 27, 2017. The two sessions of the meeting were focused on: 1) Preclinical assays and novel biotargets; and 2) monoclonal antibodies, cell therapies and targeted molecules. Between these two sessions, a lecture entitled "HLA-antigens modulation and response to immune checkpoint inhibitor immunotherapy" was also presented. Despite the impressive successes in cancer immunotherapy in recent years, the response to immune based interventions occurs only in a minority of patients (∼20%). Several basic and translational mechanisms of resistan…
Is it time to combine untargeted antifungal strategies to reach the goal of 'early' effective treatment?
2016
A recently published retrospective study by Posteraro et al. [1] investigated the use of (1–3)-β-D-glucan (BDG) as a strategy for antifungal drug administration in patients at high risk of candidemia. The strategy consisted of the administration of antifungals (anidulafungin in most cases) to septic patients with a Candida score ≥ 3a nd a positive BDG result (≥80 pg/ml). This untargeted strategy led to better selection of patients, avoiding exposure to antifungals in approximately 73 % of patients with negative BDG results and leading to shortened treatment duration in another 20 % of patients. Untargeted antifungal treatments (including prophylaxis, pre-emptive and empiric approaches) are …
Field performance of HBsAg rapid diagnostic tests in rural Ethiopia.
2020
Abstract Point-of-care rapid diagnostic tests (POC-RDTs) are widely used to screen and diagnose hepatitis B virus (HBV) infection and are often the only available diagnostic tools in resource-limited settings. The aim of this study was to evaluate the validity of three hepatitis B surface antigen (HBsAg) POC-RDTs (Healgen®, Advanced Quality™ and Determine™) in an area with high prevalence of HBV in eastern Ethiopia. Results were compared with a commercial enzyme linked immunosorbent assay (ELISA) as gold standard. Quantification of HBsAg was performed in false negative samples. A total of 511 subjects were screened, of whom 81 (15.9 %) were HBsAg-positive with the gold standard. All three P…
Short-course radiotherapy followed by chemotherapy before total mesorectal excision (TME) versus preoperative chemoradiotherapy, TME, and optional ad…
2021
BACKGROUND: Systemic relapses remain a major problem in locally advanced rectal cancer. Using short-course radiotherapy followed by chemotherapy and delayed surgery, the Rectal cancer And Preoperative Induction therapy followed by Dedicated Operation (RAPIDO) trial aimed to reduce distant metastases without compromising locoregional control. METHODS: In this multicentre, open-label, randomised, controlled, phase 3 trial, participants were recruited from 54 centres in the Netherlands, Sweden, Spain, Slovenia, Denmark, Norway, and the USA. Patients were eligible if they were aged 18 years or older, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, had a biopsy-prove…
Randomized controlled trial comparing embryo culture in two incubator systems: G185 K-System versus EmbryoScope
2017
Objective To study whether the closed culture system, as compared with a benchtop incubator with similar culture conditions, has a positive impact on intracytoplasmic sperm injection (ICSI) outcomes. Design Randomized controlled trial. Setting University hospital. Patient(s) A total of 386 patients undergoing ICSI cycles with at least six mature oocytes were randomized. Intervention(s) Of these patients, 195 were assigned to the group with culture in a time-lapse imaging (TLI) system (EmbryoScope) and 191 to the group with culture in the G185 K-System (G185). Main Outcome Measure(s) Rate of implantation (primary endpoint) and embryo morphology grade. Result(s) No significant differences wer…
“New Kids on the Block” — The Game Changers. The Role of Immune Check Point Blockade in Personalised Treatment of Prostate, Urinary Bladder and Kidne…
2021
Abstract Early detection and diagnosis of cancer followed by a personalised approach to treatment is a key and can save lives. It has been an important issue in both the medical and social fields. The search for instruments and/or diagnostics tools able to detect cancers at an early stage has led to consideration of the usage of various approaches, such as exhaled air, biomarkers in blood, urine testing as well as imaging techniques. This actual time and everything that is happening around us could be characterised as a strange and very unpredictable time. This comparison could be made not only due to the actual coronavirus situation, but also the same can be noticed in the personalised med…
Symptomatic COVID-19 in advanced-cancer patients treated with immune-checkpoint inhibitors. Prospective analysis from a multicentre observational tri…
2020
Background:This prospective, multicentre, observational INVIDIa-2 study is investigating the clinical efficacy of influenza vaccination in advanced-cancer patients receiving immune-checkpoint inhibitors (ICIs), enrolled in 82 Italian centres, from October 2019 to January 2020. The primary endpoint was the incidence of influenza-like illness (ILI) until 30 April 2020. All the ILI episodes, laboratory tests, complications, hospitalizations and pneumonitis were recorded. Therefore, the study prospectively recorded all the COVID-19 ILI events.Patients and methods:Patients were included in this non-prespecified COVID-19 analysis, if alive on 31 January 2020, when the Italian government declared …
Immunotherapeutic properties of chemotherapy
2017
IF 5.363; International audience; Impressive remissions driven by immunological checkpoint blockade in cancer patients have prompted the scientific community to investigate afresh the crosstalk between cancer cells and the patient's immune system. Preclinical and clinical studies have highlighted that the anticancer efficacy of some conventional chemotherapeutics is based on their ability to restore anticancer immune responses. The current challenge is to understand and circumvent immune resistance mechanisms to chemo- and immunotherapies to design relevant immunotherapy and chemotherapy combinations. In this review, we will summarize which immunological processes are involved in the antica…
Immunoistochemical expression of PD-1 and PD-L1 in bone marrow biopsies of patients with acute myeloid leukemia
2020
Background. Haematological and non-haematological malignancies are able to escape the host immune by the capacity to hijack the immune check-points. Several immune check-point molecules are known, such as T cell immunoglobulin mucin-3 (TIM-3), cytotoxic T-cell antigen-4 (CTLA-4), programmed death-1 (PD-1) with its ligand PD-L1 and others.1 The function of these immune check-points is to prevent the damage resulting from an excessive activation of the immune response in the setting of chronic antigenic stimulation, thus leading to autoimmune phenomena, as proved in knock-out mice models. PD-1 is normally present on activated T lymphocytes membrane, acting as a negative costimulatory receptor…
Apert Syndrome With FGFR2 758 C > G Mutation: A Chinese Case Report
2018
Background: Apert syndrome is considered as one of the most common craniosynostosis syndromes with a prevalence of 1 in 65,000 individuals, and has a close relationship with point mutations in FGFR2 gene.Case report: Here, we described a Apert syndrome case, who was referred to genetic consultation in our hospital with the symptom of craniosynostosis and syndactyly of the hands and feet. Craniosynostosis, midfacial retrusion, steep wide forehead, larger head circumference, marked depression of the nasal bridge, short and wide nose and proptosis could be found obviously, apart from these, ears were mildly low compared with normal children and there was no cleft lip and palate. Mutation was i…
