Objectives: The dysregulated immune response occurring upon COVID-19 infection can lead to tissue damage and organ failure. Different therapeutic strategies are needed to cope with the current and future outspread of COVID-19, including antiviral and anti-inflammatory agents. We describe the outcome of hospitalized patients treated with canakinumab and remdesivir plus the standard of care therapy. Methods: This observational study describes the outcome of the combination of canakinumab (450 mg for patients ≥40 and <60 kg, 600 mg for those ≥60 and <80 kg, or 750 mg for patients ≥80 kg) and 200 mg remdesivir intravenous infusion, plus standard of care (SOC), in 17 moderate-to-severe COVID-19 patients hospitalized in the "Annunziata" Hospital, Cosenza, Italy, between August and November 2021. Hematological markers, biochemical, and hemogasanalysis values at baseline versus day 7 of combination treatment were compared by paired t test after checking for normal distribution and correcting for multiple comparison. Results: The median age of patients was 64 years (range: 39-85), and the median hospitalization time (calculated on the 16 patients that were not transferred to intensive care unit) was of 12.5 days (range: 7-35 days); 15/17 patients (88%) did not experience complications. After 7 days of combination therapy, all the inflammatory parameters were significantly reduced with the exception of procalcitonin; moreover, hematological prognostic markers such neutrophil-to-lymphocyte ratio, CRP-to-lymphocyte ratio, and derived neutrophil-to-lymphocyte ratio reduced. Overall, 16/17 patients (94%) recovered after 14 days. Conclusions: Canakinumab and remdesivir treatment, in addition to SOC, in the early stage of moderate-to-severe COVID-19 showed promising outcomes in terms of safety and effectiveness potentially leading to a reduction in inflammatory and hematological prognostic markers after 7 days of treatment.

A unique report of Schönlein-Henoch purpura (SHP) associated with a recent Giardia lamblia enteric infection is described and discussed on the ground of the available literature. Tinidazole plus an appropriate probiotic therapy, including Lactobacillus reuteri and vitamin D, proved to be effective in the condition. SHP is an immunocomplex-mediated disorder characterised by a number of differently associated signs and symptoms, leading to the possible involvement of the skin, joints, abdomen and kidneys. Recent bacterial, viral, or protozoan infections may trigger the disease onset in patients of all ages. The paper describes the first case of SHP triggered by a giardiasis. Tinidazole plus an appropriate probiotic therapy, i.e. L. reuteri and vitamin D proved to be effective in this condition. To our knowledge, this is the first reported case of lambliasis-associated SHP described in an international traveller.

Thrombotic thrombocytopenic purpura (TTP) is a potentially life-threatening, rare acute thrombotic microangiopathy (TMA), caused by a severe ADAMTS13 deficiency. As the COVID-19 pandemic rapidly spread around the globe, much data about the pathogenicity of this virus were published. Soon after the detection of the first cases of COVID-19, it was clear that there was a wide range of COVID coagulopathy manifestations, such as deep venous thrombosis, pulmonary thromboembolism, and thrombotic microangiopathies. In the literature, little data have been reported about the association between TTP and COVID-19, and the treatment of COVID-19-associated TTP is still under debate. Here we present the case of a 46-year-old woman who developed a COVID-associated TTP, successfully treated with plasma exchange (PEX), steroids, and caplacizumab.
RESUMEN
Both the safety and effectiveness of intrathecal tigecycline (TGC) for treatment of infections of the central nervous system (CNS) are discussed using the clinical findings from a study of a recent patient who came to our attention, along with a literature review. Although penetration into the CNS is low (approximately 11%), intraventricular TGC could help treat patients with severe post- neurosurgical CNS infections. The use of multiple routes of TGC administration appears to be encouraging and should be considered in managing life-threatening intraventricular infections.

Glecaprevir (GLE)/pibrentasvir (PIB) is a pangenotypic direct-acting antiviral regimen approved for treating chronic hepatitis C virus. Primary treatment and re-treatment with GLE/PIB are effective and safe for patients without decompensated liver cirrhosis and chronic hepatitis C in a real-world clinical setting. However, in the context of compensated cirrhosis and concomitant administration of inhibitors of cytochromes, a careful monitoring of liver biomarkers, as well as therapeutic drug monitoring (TDM), may be advisable during GLE/PIB therapy. The GLE / PIB combination is very effective and safe in achieving a sustained virological response, but it can be associated with the development of severe hepatic adverse events, which require virological and serum concentration monitoring of the two drugs to prevent a serious liver damage. The possible onset of hyperbilirubinemia must not necessarily lead to the suspension of therapy, because the phenomenon may be transient. We report what is likely the first known case of severe jaundice after treatment with GLE/PIB in Italy in a patient with compensated chronic hepatitis in the context of HIV disease.

This brief report documents the safety and efficacy of high-dose tigecycline as a salvage-therapy in in a case series of five patients with serious central nervous system (CNS) rocky mountain spotted fever (RMSF). These severily ill patients were unable to take any oral drug therapy, parenteral doxycycline was unavailable and absorption of oral doxycycline was a concern in these critically ill patients. As far as we know, we report the successfull use of tigecycline for the treatment of rickettsial meningitis for the first time in Italy. We suggest more studies on tigecycline in severe CNS infections from Rickettsia species and multi-drug resistant bacteria, especially the use of tigecycline at higher than standard doses in these life-threathening infectious diseases.
RESUMEN
INTRODUCTION: The fully-human monoclonal anti-interleukin (IL)-1ß antibody canakinumab may inhibit the production of inflammatory mediators in patients with coronavirus disease 2019 (COVID-19) and the hyperinflammatory response potentially leading to acute respiratory distress syndrome. OBJECTIVES: The goal of our retrospective, observational analysis was to evaluate the safety and efficacy of subcutaneous (s.c.) canakinumab in combination with our standard of care (SOC) treatment of selected patients with COVID-19 with respiratory failure and elevated reactive pro-inflammatory markers. METHODS: Eight participants received two doses of s.c. canakinumab 150 mg (or 2 mg/kg for participants weighing ≤40 kg) in addition to SOC. 12 patients received only SOC treatment. RESULTS: Canakinumab treatment reduced the need for mechanical ventilation and reduced proinflammatory markers, resulting in an amelioration of the final outcome, with respect to the control group who received SOC alone. The treatment was safe and well tolerated; no adverse events were reported. CONCLUSION: The use of canakinumab (300 mg, s.c.) in the early stage of COVID-19 with mild-to-moderate respiratory failure was superior to SOC at preventing clinical deterioration and may warrant further investigation as a treatment option for patients with COVID-19 who experience a hyperinflammatory response in the early stage of the disease.

Ivabradine is a pure heart rate-lowering drug that acts directly on the sinus node and does not affect atrioventricular or intraventricular conduction times, myocardial contractility or ventricular repolarization. Ivabradine is used in the treatment of adults with New York Heart Association (NYHA) class II-IV chronic heart failure (CHF) with systolic dysfunction, in sinus rhythm, with a heart rate of ≥75 beats per minute (bpm). This report describes the beneficial effect of ivabradine on clinical parameters in a HIV-infected patient with dilated cardiomyopathy presenting with NYHA class III CHF symptoms. Ivabradine improved functional capacity and left ventricular (LV) systolic function in our patient with HIV-related dilated cardiomyopathy and CHF. This report also lists the summaries of potential clinically significant interaction, likely to require additional monitoring, alteration of drug dosage or timing of administration, between ivabradine and antiretroviral drugs.

Oseltamivir is an orally administered antiviral medication that selectively inhibits the influenza neuraminidase enzymes that are essential for viral replication and it is active against both influenza A and B viruses. Oseltamivir is indicated for therapy or post-exposure prevention of influenza A and B. Side effects are uncommon and include mild nausea, gastrointestinal upset, dizziness, and headache. Despite widespread use, oseltamivir has not been associated with clinically apparent liver injury; however, there is growing evidence of possible toxic liver involvement during oseltamivir therapy. To the best of our knowledge, this is the first reported case in Italy linking the development of acute hepatitis and oseltamivir therapy, in a patient suffering from influenza H1N1 infection. We also present a review of the literature on cases of oseltamivir hepatotoxicity, through the consultation of PubMed database, the bibliographical references of various articles and an extensive search using Google. In view of the analyzed results, we suggest that experts should carefully consider the need for inclusion of potential serious liver reactions be added to the oseltamivir product label.

BACKGROUND: Patients with severe coronavirus disease 2019 (COVID-19) have elevated levels of acute phase reactants and inflammatory cytokines, including interleukin-6, indicative of cytokine release syndrome (CRS). The interleukin-6 receptor inhibitor tocilizumab is used for the treatment of chimeric antigen receptor T-cell therapy-induced CRS. METHODS: Patients aged 18 years or older with laboratory-confirmed COVID-19 admitted to the Annunziata Hospital in Cosenza, Italy, through March 7, 2020, who received at least one dose of tocilizumab 162 mg subcutaneously for the treatment of COVID-19-related CRS in addition to standard care were included in this retrospective observational study. The primary observation was the incidence of grade 4 CRS after tocilizumab treatment. Chest computed tomography (CT) scans were evaluated to investigate lung manifestations. FINDINGS: Twelve patients were included; all had fever, cough, and fatigue at presentation, and all had at least one comorbidity (hypertension, six patients; diabetes, five patients; chronic obstructive lung disease, four patients). Seven patients received high-flow nasal cannula oxygen therapy and five received non-invasive mechanical ventilation for lung complications of COVID-19. No incidence of grade 4 CRS was observed within 1 week of tocilizumab administration in all 12 patients (100%) and within 2 days of tocilizumab administration in 5 patients (42%). The predominant pattern on chest CT scans at presentation was ground-glass opacity, air bronchograms, smooth or irregular interlobular or septal thickening, and thickening of the adjacent pleura. Follow-up CT scans 7 to 10 days after tocilizumab treatment showed improvement of lung manifestations in all patients. No adverse events or new safety concerns attributable to tocilizumab were reported. INTERPRETATION: Tocilizumab administered subcutaneously to patients with COVID-19 and CRS is a promising treatment for reduction in disease activity and improvement in lung function. The effect of tocilizumab should be confirmed in a randomised controlled trial.
