[Practical approach to the patient with fever in the intensive cardiac care unit: diagnostic framework and therapy notes].

The management of the patient with fever in the intensive cardiac care unit begins with a thorough evaluation of the patient, particularly symptoms, clinical history and physical examination, to provide information regarding the origin of the fever. The global evaluation of the patient should be integrated with blood and microbiological tests, in particular blood culture and swab. The laboratory, microbiologic or radiologic tests could be more or less detailed and targeted depending on the type of suspected infection and clinical conditions of the patient.

Clinical efficacy of different monoclonal antibody regimens among non-hospitalised patients with mild to moderate COVID-19 at high risk for disease progression: a prospective cohort study.

This study aimed to compare the clinical progression of COVID-19 in high-risk outpatients treated with the monoclonal antibodies (mAb) bamlanivimab, bamlanivimab-etesevimab and casirivimab-imdevimab. This is an observational, multi-centre, prospective study conducted from 18 March to 15 July 2021 in eight Italian tertiary-care hospitals including mild-to-moderate COVID-19 outpatients receiving bamlanivimab (700 mg), bamlanivimab-etesevimab (700-1400 mg) or casirivimab-imdevimab (1200-1200 mg). All patients were at high risk of COVID-19 progression according to Italian Medicines Agency definitions.

Prompt Hematological Recovery in Response to a Combination of Pegylated Interferon α-2a and Rituximab in a Profoundly Immuno-Suppressed Hairy Cell Leukemia Patient with a Mycobacterial Infection at Onset: Benefits and Drawbacks of Rapid Immune Reconstitution.

The present paper reports, to the best of our knowledge for the first time, the efficacy and tolerability of the combination of interferon (IFN)α-2a in pegylated formulation and rituximab after a "priming" phase with IFN in the frontline treatment of hairy cell leukemia (HCL) in a profoundly immunosuppressed patient with a infection at onset. This immunotherapy combination may represent a potential therapeutic option in patients with active severe infection and for whom the use of purine nucleoside analogues (PNA) is contraindicated. The benefits and drawbacks of remarkably rapid immune reconstitution in the context of opportunistic infections are highlighted as well, as the potentially paradoxical effects of immune recovery as a result of effective immunotherapy strategies, known as immune reconstitution inflammatory syndrome (IRIS), have to be taken into account when dealing with patients with opportunistic infections.

COVID-19 in B Cell-Depleted Patients After Rituximab: A Diagnostic and Therapeutic Challenge.

B cell-targeting strategies such as rituximab are widely used in B cell hematologic malignancies, rheumatologic and musculoskeletal diseases and a variety of autoimmune disorders. The purpose of this paper is to illustrate how exposure to anti-CD20 treatment profoundly affects B cell functions involved in anti-SARS-CoV-2 immunity and significantly impacts on the clinical and serological course of SARS-CoV-2 infection, long term immunity and vaccine responses. The data presented here suggest that the effects of B cell-depleting agents on adaptive immunity should be taken into account for the proper selection and interpretation of SARS-CoV-2 diagnostics and to guide appropriate therapeutic approaches and protective measures.

Dramatic Response to Convalescent Hyperimmune Plasma in Association With an Extended Course of Remdesivir in 4 B Cell-Depleted Non-Hodgkin Lymphoma Patients With SARS-Cov-2 Pneumonia After Rituximab Therapy.

• Four B cell–depleted non-Hodgkin lymphoma (NHL) patients with SARS-CoV-2 pneumonia after rituximab therapy were initially treated with a 5-day remdesivir course and steroids. After transient virologic and clinical response, they all experienced early relapse and subsequent prolonged disease course, with rapid and significant response to convalescent hyperimmune plasma in association with an extended course of remdesivir. The clinical observations here reported suggest that the immunological effects of Rituximab treatment in NHL patients should be taken into account for the proper choice and interpretation of SARS-CoV-2 laboratory tests and to guide the appropriate therapeutical approach.

Suppression of Covid-19 outbreak among healthcare workers at the Treviso Regional Hospital, Italy and lessons for ophthalmologists.

Purpose: To describe a strategy to reduce Covid-19 spread among healthcare workers and provide ophthalmologists with recommendations useful for a possible second wave of Covid-19 in Autumn.

Methods: Epidemiological surveillance at the Cà Foncello Hospital (Veneto, Italy) since 24 February 2020 to 24 April 2020 when the municipality of Treviso was hit by the Covid-19 outbreak. The number of naso-pharigeal (NP) swabs performed was 7010.

Progressive disseminated histoplasmosis among human immunodeficiency virus-infected patients from West-Africa: report of four imported cases in Italy.

We report four imported cases of progressive disseminated histoplasmosis (PDH) due to Histoplasma capsulatum variety capsulatum in Human Immunodeficiency Virus-infected patients from West Africa. This report highlights the need to consider diagnosis of PDH among patients with acquired immunodeficiency syndrome who originate from West Africa and present with a prolonged febrile illness and very low CD4 count.

Infective endocarditis in patients with diabetes mellitus.

Background And Aim Of The Study: Numerous studies have been conducted to investigate the conditions associated with poor outcome among patients with infective endocarditis (IE). Yet, diabetes mellitus alone has rarely been analyzed as participating in the prognosis, and few data are available relating to the clinical characteristics of IE in diabetics. The study aim was to assess the influence of diabetes mellitus on the characteristics and prognosis of IE, and to identify predictors of poor outcome among diabetic patients with this condition.
