Efficacy and Safety of Nirmatrelvir/Ritonavir, Molnupiravir, and Remdesivir in a Real-World Cohort of Outpatients with COVID-19 at High Risk of Progression: The PISA Outpatient Clinic Experience.

Introduction: Different antivirals are available for the treatment of outpatients with COVID-19. Our aim was to describe a real-world experience of outpatient management of COVID-19 subjects at high risk of progression.

Methods: This prospective observational study conducted in the University Hospital of Pisa (January 2022-July 2022) included consecutive COVID-19 outpatients with at least one risk factor for disease progression.

An octopus gift: Mycobacterium marinum multiple skin lesions.

Mycobacterium marinum is a nontuberculous mycobacterium responsible of infections in humans, ranging from skin infection to disseminated infection in immunocompromised hosts. Clinical suspicion and prompt diagnosis are crucial to prescribe appropriate antimycobacterial treatment and avoid sequelae.

Cardiovascular implantable electronic device endocarditis treated with daptomycin with or without transvenous removal.

Background And Methods: Nine patients with cardiovascular implantable electronic device (CIED) endocarditis were treated with daptomycin after the failure of previous treatment. The blood and CIED lead cultures of 1 patient were negative. In the other 8 patients, we observed 6 monomicrobic infections and 2 polymicrobic infections.

Acute varicella-zoster virus necrotizing meningoencephalomyelitis with sudden visual loss and paraparesis in an HIV-infected patient.

We describe a case of acute varicella-zoster virus (VZV) hemorrhagic meningoencephalomyelitis in an HIV-infected patient. On admission the patient's CSF was mild haemorrhagic and xanthochromic after centrifugation and he had thoracic skin blisters. VZV DNA was isolated from both the thoracic blisters and CSF.

Hepatitis C virus genotypes in the liver and serum of patients with chronic hepatitis C.

OBJECTIVE: To evaluate the prevalence of hepatitis C virus (HCV) genotypes in a central area of Italy (Umbria); to analyze the correspondence of the genotypes detected in serum and liver samples; to study the relationship between HCV genotypes and severity of liver disease; to test whether co-infection with more than one HCV subtype could be influenced by the source of infection. METHODS: Genotyping by polymerase chain reaction with core-specific primers (Okamoto method) was performed in the serum and liver from 48 consecutive patients with histologically confirmed chronic C hepatitis. RESULTS: HCV genotype 1b was the prevalent strain and was not associated with more severe histologic damage.
