COVID-19 Vaccine in Lung and Liver Transplant Recipients Exceeds Expectations: An Italian Real-Life Experience on Immunogenicity and Clinical Efficacy of BNT162b2 Vaccine.

This study assessed humoral and T cell-mediated immune responses to the BNT162b2 vaccine in orthotopic liver transplant (OLT) and lung transplant (LUT) recipients who received three doses of the vaccine from March 2021 at our institution. Serum samples were collected 60 days post-second and third dose to quantify antibodies against the spike region of SARS-CoV-2 while whole blood samples were collected to analyze the SARS-CoV-2-specific T-cell response using an IFN-γ ELISpot assay. We enrolled 244 OLT and 120 LUT recipients.

Impact of COVID-19 on the quality of life of patients with neuromuscular disorders in the Lombardy area, Italy.

Introduction: /AIMS: Patients with neuromuscular disorders (NMDs), including many elderly, immunosuppressed, and disabled individuals, may have been particularly affected during the coronavirus disease 2019 (COVID-19) pandemic in Lombardy, a COVID-19 high-incidence area between February and May 2020. We aimed to evaluate the effects of the COVID-19 pandemic on the quality of life (QoL) and perceived disease burden of this group of patients.

Methods: We conducted a cross-sectional phone-based survey study between June 1 and June 14, 2020, on a sample of 240 NMD patients followed at our clinic in Milan, Italy.

Animal Models of CMT2A: State-of-art and Therapeutic Implications.

Charcot-Marie-Tooth disease type 2A (CMT2A), arising from mitofusin 2 (MFN2) gene mutations, is the most common inherited axonal neuropathy affecting motor and sensory neurons. The cellular and molecular mechanisms by which MFN2 mutations determine neuronal degeneration are largely unclear. No effective treatment exists for CMT2A, which has a high degree of genetic/phenotypic heterogeneity.

Neural Stem Cell Transplantation for Neurodegenerative Diseases.

Neurodegenerative diseases are disabling and fatal neurological disorders that currently lack effective treatment. Neural stem cell (NSC) transplantation has been studied as a potential therapeutic approach and appears to exert a beneficial effect against neurodegeneration via different mechanisms, such as the production of neurotrophic factors, decreased neuroinflammation, enhanced neuronal plasticity and cell replacement. Thus, NSC transplantation may represent an effective therapeutic strategy.

Glial cells involvement in spinal muscular atrophy: Could SMA be a neuroinflammatory disease?

Spinal muscular atrophy (SMA) is a severe, inherited disease characterized by the progressive degeneration and death of motor neurons of the anterior horns of the spinal cord, which results in muscular atrophy and weakness of variable severity. Its early-onset form is invariably fatal in early childhood, while milder forms lead to permanent disability, physical deformities and respiratory complications. Recently, two novel revolutionary therapies, antisense oligonucleotides and gene therapy, have been approved, and might prove successful in making long-term survival of these patients likely.

Challenges and prospects in the diagnosis and treatment of primary central nervous system lymphoma.

: Primary central nervous system lymphoma (PCNSL) retains peculiar biological and clinical characteristics and a worse prognosis with respect to other comparable lymphomas. The need for high doses of chemotherapy to achieve valid drug concentrations in cerebral tissues and/or radiotherapy results in severe treatment-related toxicities, mainly neurologic, which are frequently as disabling as the disease itself.: Several emerging combined therapies are addressed that focus on treating PCNSL.

Primary central nervous system lymphoma.

Primary CNS lymphomas (PCNSL) represent a subgroup of malignancies with specific characteristics, aggressive course, and unsatisfactory outcome in contrast with other lymphomas comparable for tumour burden and/or histological type. Despite a high chemo- and radiosensitivity, remissions are frequently shortlasting, mainly because the blood brain-barrier limits the access of many drugs to the CNS. Moreover, survivor patients are at high risk of developing severe treatment-related toxicity, mainly disabling neurotoxicity, raising the question of how to balance therapy intensification with side-effects control.

Clinical predictors and microbiology of ventilator-associated pneumonia in the intensive care unit: a retrospective analysis in six Italian hospitals.

The purpose of this study was to assess the main clinical predictors and microbiological features of ventilator-associated pneumonia (VAP) in the Intensive Care Unit (ICU) environment. This work is a retrospective analysis over one year from September 2010 to September 2011. Patients' risk factors, causes of admission, comorbidities and respiratory specimens collected in six Italian ICUs were reviewed.

Present and future treatment options for primary CNS lymphoma.

Introduction: Primary Central Nervous System (CNS) lymphomas are a rare group of malignancies with peculiar clinical and biologic features, aggressive course, and unsatisfactory outcome in contrast with other aggressive lymphomas. Despite a high chemo- and radiosensitivity, remissions are frequently short lasting, mainly because the blood-brain barrier limits the access of many drugs to the CNS, preventing a homogeneous treatment of all CNS tissues. Moreover, survivor patients are at high risk of developing severe treatment-related toxicity, mainly disabling neurotoxicity for elderly ones, raising the question of whether to intensify therapy to improve the cure rate or to downgrade treatment to reduce side effects.

High Doses of Antimetabolites Followed by High-Dose Sequential Chemoimmunotherapy and Autologous Stem-Cell Transplantation in Patients With Systemic B-Cell Lymphoma and Secondary CNS Involvement: Final Results of a Multicenter Phase II Trial.

Purpose: Treatment of secondary CNS dissemination in patients with aggressive lymphomas remains an important, unmet clinical need. Herein, we report the final results of a multicenter phase II trial addressing a new treatment for secondary CNS lymphoma based on encouraging experiences with high doses of antimetabolites in primary CNS lymphoma and with rituximab plus high-dose sequential chemoimmunotherapy (R-HDS) in relapsed aggressive lymphoma.

Patients And Methods: HIV-negative patients with aggressive B-cell lymphoma and secondary CNS involvement at diagnosis or relapse, age 18 to 70 years, and Eastern Cooperative Oncology Group performance status ≤ 3 were enrolled and treated with high-doses of methotrexate and cytarabine, followed by R-HDS (cyclophosphamide, cytarabine, and etoposide) supported by autologous stem-cell transplantation (ASCT).

Microbiologic characteristics and predictors of mortality in bloodstream infections in intensive care unit patients: A 1-year, large, prospective surveillance study in 5 Italian hospitals.

Background: Bloodstream infections (BSIs) from multidrug-resistant (MDR) bacteria cause morbidity and mortality in intensive care unit (ICU) patients worldwide. This study investigated the incidence of BSIs in 5 adult general ICUs in Rome, Italy, and evaluated the mortality rate and risk factors associated with these infections.

Methods: Over a 12-month period, 1,318 patients were enrolled.

Risk-tailored CNS prophylaxis in a mono-institutional series of 200 patients with diffuse large B-cell lymphoma treated in the rituximab era.

The most effective strategy to prevent central nervous system (CNS) dissemination in diffuse large B-cell lymphoma (DLBCL) remains an important, unmet clinical need. Herein, we report a retrospective analysis of risk-tailored CNS prophylaxis in 200 human immunodeficiency virus-negative adults with DLBCL treated with rituximab-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) or similar. High risk of CNS relapse was defined by involvement of specific extranodal organs, or simultaneous presence of advanced stage and high serum lactate dehydrogenase level; CNS prophylaxis with high-dose methotrexate ± intrathecal chemotherapy (IT) was routinely used in high-risk patients diagnosed after 2007.

Current uses of radiation therapy in patients with primary CNS lymphoma.

High-dose methotrexate (HD-MTX)-based chemotherapy is the current first-line therapy for primary CNS lymphoma. Whole-brain radiotherapy (WBRT) plays an important role in the management of primary CNS lymphoma and is indicated in patients with contraindication to chemotherapy, in patients with unusual histologic subtypes as curative treatment, as complementary therapy for patients failing to achieve complete remission after systemic chemotherapy and as salvage therapy for refractory or relapsing patients when systemic chemotherapy is no longer advisable. The two major pitfalls in WBRT use are transitory efficacy and neurotoxicity with deterioration of quality of life.

[The primary mediastinal lymphoma: state of the art and therapeutical perspectives].

Within diffuse large B-cell lymphomas, the Primary Mediastinal Large B-Cell Lymphoma has to be considered as a separate and well-defined clinico-pathological entity. Its tendency to target young adults makes its social impact particularly significant; hence, the General Practitioner carries the responsibility for an early diagnosis. On the contrary, the extreme complexity of the available therapies makes a quick referral to specialized Clinical Centres of outmost importance, since this remains the best way to enrol as many patients as possible in therapeutic protocols.

Background: NGR-hTNF consists of human tumour necrosis factor-alpha (hTNF-alpha) fused to the tumour-homing peptide NGR, a ligand of an aminopeptidase N/CD13 isoform, which is overexpressed on endothelial cells of newly formed tumour blood vessels. NGR-TNF showed a biphasic dose-response curve in preclinical models. This study exploring the low-dose range aimed to define safety and optimal biological dose of NGR-hTNF.

Phase Ib study of NGR-hTNF, a selective vascular targeting agent, administered at low doses in combination with doxorubicin to patients with advanced solid tumours.

Background: Asparagine-glycine-arginine-human tumour necrosis factor (NGR-hTNF) is a vascular targeting agent exploiting a tumour-homing peptide (NGR) that selectively binds to aminopeptidase N/CD13, overexpressed on tumour blood vessels. Significant preclinical synergy was shown between low doses of NGR-TNF and doxorubicin.

Methods: The primary aim of this phase I trial was to verify the safety of low-dose NGR-hTNF combined with doxorubicin in treating refractory/resistant solid tumours.

Cytokine secretion associated with the clearance of apoptotic bodies in renal cell carcinoma patients.

The factors determining the outcome of immunotherapy in metastatic renal cell carcinoma (RCC) patients remain elusive. Macrophages from normal donors that phagocytose apoptotic cells secrete the immunosuppressive cytokine IL-10 in vitro. Conversely, IL-10 genetic deletion enhances the immunogenicity of apoptotic tumor cells in vivo.

In vivo administration of GM-CSF promotes the clearance of apoptotic cells: effects on monocytes and polymorphonuclear leukocytes.

The clearance of apoptotic cells is crucial to avoid chronic inflammation and autoimmunity. Little is known about the factors that regulate it in vivo. We show that granulocyte-macrophage colony-stimulating factor (GM-CSF) administration to carcinoma patients confers to their leukocytes a significantly higher ability to phagocytose apoptotic cells than before (P < 0.
