Delayed Surgical Treatment of a CE1 Lung Cyst Resulting in Pericystectomy of CE4 Cyst.

Lung is the second most common locationof cystic echinococcosis (CE), after the liver. Diagnosis of lung CE is often incidental, and clinical manifestations depend on the location and size of the cyst, the most common being chest pain, shortness of breath, expectoration of fragments of endocyst, and haemoptysis. Surgery is the primary treatment, with a minor role for medical therapy. Delayed diagnosis and treatment may have important consequences. We present a case of lung CE in whichsurgical treatment was delayed due to the first wave of COVID-19. Since surgery could not be performed immediately, the patient was kept on albendazole and the cyst stage moved from CE1 to CE3a, to CE4, eventually requiring a more aggressive pericystectomy instead of the commonly performed endocystectomy. The clinical and imaging characteristics of a rare CE4 cyst of the lung are reported.

New Insights into the Identification of Metabolites and Cytokines Predictive of Outcome for Patients with Severe SARS-CoV-2 Infection Showed Similarity with Cancer.

SARS-CoV-2 infection is characterized by several clinical manifestations, ranging from the absence of symptoms to severe forms that necessitate intensive care treatment. It is known that the patients with the highest rate of mortality develop increased levels of proinflammatory cytokines, called the "cytokine storm", which is similar to inflammatory processes that occur in cancer. Additionally, SARS-CoV-2 infection induces modifications in host metabolism leading to metabolic reprogramming, which is closely linked to metabolic changes in cancer. A better understanding of the correlation between perturbed metabolism and inflammatory responses is necessary. We evaluated untargeted plasma metabolomics and cytokine profiling via 1H-NMR (proton nuclear magnetic resonance) and multiplex Luminex assay, respectively, in a training set of a limited number of patients with severe SARS-CoV-2 infection classified on the basis of their outcome. Univariate analysis and Kaplan-Meier curves related to hospitalization time showed that lower levels of several metabolites and cytokines/growth factors, correlated with a good outcome in these patients and these data were confirmed in a validation set of patients with similar characteristics. However, after the multivariate analysis, only the growth factor HGF, lactate and phenylalanine retained a significant prediction of survival. Finally, the combined analysis of lactate and phenylalanine levels correctly predicted the outcome of 83.3% of patients in both the training and the validation set. We highlighted that the cytokines and metabolites involved in COVID-19 patients' poor outcomes are similar to those responsible for cancer development and progression, suggesting the possibility of targeting them by repurposing anticancer drugs as a therapeutic strategy against severe SARS-CoV-2 infection.

Endobronchial hamartoma in a young COVID-19 symptomatic woman. Radical endoscopic treatment with a disposable bronchoscope. Case Report.

Pulmonary hamartomas represent the most frequent family of benign lung tumors that typically involve the lung parenchyma and only rarely grow as endobronchial tumors. The elective treatment of endobronchial hamartoma is the bronchoscopic resection, and in those cases in which tumor extension and localization makes it not possible, surgical treatment must be evaluated. Patients with symptomatic COVID-19, hospitalized, frequently undergo a chest CT scan and in some cases, occasional findings may emerge, requiring diagnostic investigations such as bronchoscopy and interventional pulmonology procedures. Therefore, in such a delicate pathological condition, such as COVID-19, the need to perform bronchoscopy and interventional pulmonology procedures, minimizing the risk of viral transmission and ensuring necessary assistance, represents a great challenge for pulmonologists. In this article authors describe, for the first time in literature, a rare case of endobronchial hamartoma, radically resected using a single use bronchoscope, in a young female patient hospitalized for symptomatic COVID-19.

Atypical COVID-19 dynamics in a patient with mantle cell lymphoma exposed to rituximab.

Patients with non-hodgkin lymphomas (NHL) represent a population of special interest during the current Coronavirus disease-19 (COVID-19) pandemics. NHLs are associated with disease- and treatment-related immunodeficiencies which may generate unusual COVID-19 dynamics and pose unique management challenges. We report the unusual clinical course of COVID-19 in a patient with mantle cell lymphoma (MCL) exposed to nine doses of Rituximab shortly before infection with severe acute respiratory syndrome corona virus 2 (SARS-CoV-2). He had a prolonged asymptomatic phase, with negative molecular and antibody testing for SARS-CoV-2, followed by a rapidly progressive evolution to severe COVID-19. Despite detection of viral RNA overlapped with first symptoms occurrence, anti-SARS-CoV-2 antibodies displayed an asynchronous pattern, with IgG first appearing 2 days after RNA positivity and IgM never being detected throughout the entire clinical course. While disease-associated immune derangements and/or previous treatments involving anti-CD20 antibodies might have contributed to COVID-19 dynamics in our patient, data suggests that antibody testings, without concurrent molecular assessment for SARS-CoV-2, may turn inadequate for monitoring of MCL patients, and in general NHL patients heavily exposed to anti-CD20 antibodies, during the current pandemics. We suggest that repeated molecular testing of nasopharyngeal swab should be implemented in these subjects despite a negative serology and absence of symptoms of SARS-CoV-2 infection. For the same reasons, a customized strategy needs to be developed for patients exposed to anti-CD20 antibodies, based on different features and mechanism of action of available SARS-CoV-2 vaccines and novel vaccinomics developments.

Impact of chronic liver disease upon admission on COVID-19 in-hospital mortality: Findings from COVOCA study.

BACKGROUND: Italy has been the first Western country to be heavily affected by the spread of SARS-COV-2 infection and among the pioneers of the clinical management of pandemic. To improve the outcome, identification of patients at the highest risk seems mandatory. OBJECTIVES: Aim of this study is to identify comorbidities and clinical conditions upon admission associated with in-hospital mortality in several COVID Centers in Campania Region (Italy). METHODS: COVOCA is a multicentre retrospective observational cohort study, which involved 18 COVID Centers throughout Campania Region, Italy. Data were collected from patients who completed their hospitalization between March-June 2020. The endpoint was in-hospital mortality, assessed either from data at discharge or death certificate, whilst all exposure variables were collected at hospital admission. RESULTS: Among 618 COVID-19 hospitalized patients included in the study, 143 in-hospital mortality events were recorded, with a cumulative incidence of about 23%. At multivariable logistic analysis, male sex (OR 2.63, 95%CI 1.42-4.90; p = 0.001), Chronic Liver Disease (OR 5.88, 95%CI 2.39-14.46; p<0.001) and malignancies (OR 2.62, 95%CI 1.21-5.68; p = 0.015) disclosed an independent association with a poor prognosis, Glasgow Coma Scale (GCS) and Respiratory Severity Scale allowed to identify at higher mortality risk. Sensitivity analysis further enhanced these findings. CONCLUSION: Mortality of patients hospitalized for COVID-19 appears strongly affected by both clinical conditions on admission and comorbidities. Originally, we observed a very poor outcome in subjects with a chronic liver disease, alongside with an increase of hepatic damage.

Immunocytometric analysis of COVID patients: A contribution to personalized therapy?

AIMS: This study aims to cast light on immunocytometric alterations in COVID-19, a potentially fatal viral infection with heterogeneous clinical expression and a not completely defined pathophysiology. METHODS: We studied 35 COVID patients at hospital admission testing by cytofluorimetry a large panel of lymphocyte subpopulations and serum tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-17A and the soluble receptor of IL-17A (IL-17RA). KEY FINDINGS: At hospital admission, total lymphocytes and most T and B subpopulations were reduced in 50-80% of patients, with close relationship to disease severity. While activated T helper 1 (TH1) and TH17 cells resulted normal or higher. Serum IL-6 was increased in all patients, while TNF-α and IL-17A were higher in advanced stages. A patient subset with low severity had very high IL-17RA levels. Tocilizumab treatment caused an increase of IL-17A in 3/6 patients and a reduction in 3 others, while the lymphocyte number increased in 3 patients and did not change in the others. SIGNIFICANCE: Cytofluorimetry revealed a functional exhaustion of most lymphocyte populations in COVID patients not involving activated TH1 and TH17. Consequently, there was a relevant cytokines production that contributes to impair the respiratory inflammation. The increase of TH17 and IL-17 in a subset of cases and the evidence of a significant increase of IL-17RA (that prevents the interaction of IL-17 with the cell receptor) in patients with low severity suggest that some patients could benefit from monoclonal antibodies treatment targeting IL-17 pathway. Immunocytofluorimetric markers may contribute to a personalized therapy in COVID patients.

Covid-19 and the role of smoking: the protocol of the multicentric prospective study COSMO-IT (COvid19 and SMOking in ITaly).

The emergency caused by Covid-19 pandemic raised interest in studying lifestyles and comorbidities as important determinants of poor Covid-19 prognosis. Data on tobacco smoking, alcohol consumption and obesity are still limited, while no data are available on the role of e-cigarettes and heated tobacco products (HTP). To clarify the role of tobacco smoking and other lifestyle habits on COVID-19 severity and progression, we designed a longitudinal observational study titled COvid19 and SMOking in ITaly (COSMO-IT). About 30 Italian hospitals in North, Centre and South of Italy joined the study. Its main aims are: 1) to quantify the role of tobacco smoking and smoking cessation on the severity and progression of COVID-19 in hospitalized patients; 2) to compare smoking prevalence and severity of the disease in relation to smoking in hospitalized COVID-19 patients versus patients treated at home; 3) to quantify the association between other lifestyle factors, such as e-cigarette and HTP use, alcohol and obesity and the risk of unfavourable COVID-19 outcomes. Socio-demographic, lifestyle and medical history information will be gathered for around 3000 hospitalized and 700-1000 home-isolated, laboratory-confirmed, COVID-19 patients. Given the current absence of a vaccine against SARS-COV-2 and the lack of a specific treatment for -COVID-19, prevention strategies are of extreme importance. This project, designed to highly contribute to the international scientific debate on the role of avoidable lifestyle habits on COVID-19 severity, will provide valuable epidemiological data in order to support important recommendations to prevent COVID-19 incidence, progression and mortality.

Incidental diagnosis of lung adenocarcinoma following coronavirus OC 43 severe pneumonia.

Viral infections are frequent among patients with thoracic malignancies prompted by dysregulation of innate and adaptative immune response. Clinical symptoms and radiological findings of both viral pneumonia and lung adenocarcinoma may overlap resulting in diagnostic and clinical  challenges.We present the case of a women admitted to our department presenting with an acute manifestation of coronavirus OC43 pneumonia with underlying undiagnosed lung adenocarcinoma.

COVID-19 and the elderly: insights into pathogenesis and clinical decision-making.

The elderly may represent a specific cluster of high-risk patients for developing COVID-19 with rapidly progressive clinical deterioration. Indeed, in older individuals, immunosenescence and comorbid disorders are more likely to promote viral-induced cytokine storm resulting in life-threatening respiratory failure and multisystemic involvement. Early diagnosis and individualized therapeutic management should be developed for elderly subjects based on personal medical history and polypharmacotherapy. Our review examines the pathogenesis and clinical implications of ageing in COVID-19 patients; finally, we discuss the evidence and controversies in the management in the long-stay residential care homes and aspects of end-of-life care for elderly patients with COVID-19.

The role of CEUS in characterization of superficial lymph nodes: a single center prospective study.

Accurate lymph node characterization is important in a large number of clinical settings. We evaluated the usefulness of Contrast Enhanced Ultrasound (CEUS) in distinguishing between benign and malignant lymph nodes compared with conventional ultrasonography in the differential diagnosis of superficial lymphadenopathy.We present our experience for 111 patients enrolled in a single center.111 superficial lymph nodes were selected and only 1 lymph node per patient underwent CEUS. A definitive diagnosis for all lymph nodes was obtained by ultrasonographically guided biopsy and/or excision biopsy.The size of the lymph nodes, the site (neck, axilla, inguinal region) being easily accessible for biopsy, and the US and color Doppler US characteristics guided us in selecting the nodes to be evaluated by CEUS.In our study we identified different enhancement patterns in benign and malignant lymph nodes, with a high degree of diagnostic accuracy for superficial lymphadenopathy in comparison with conventional US.

Amprenavir inhibits the migration in human hepatocarcinoma cell and the growth of xenografts.

The introduction of HAART (highly-active-antiretroviral-therapy) has resulted in extended survival of HIV positive patients. Conversely, due to the prolonged expectancy of life and the ageing of the HIV positive population, tumors are now one of the major cause of death, and among them hepatocellular carcinoma (HCC) has become a growing concern in these patients. Considering the potential anti-tumoral effects of HIV protease inhibitors, we decided to evaluate the anti-tumoral activity of Amprenavir on liver carcinoma and to evaluate its potential synergistic effects in combination with standard chemoterapic drugs, such as Doxorubicin. Our results indicate that Amprenavir had direct inhibitory effects on invasion of Huh-7 hepatocarcinoma cell lines, inhibiting MMP proteolytic activation. Amprenavir was able to delay the growth of hepatocarcinoma xenografts in nude mice and had a synergistic effect with Doxorubicin. Furthermore, Amprenavir was able to promote regression of hepatocarcinoma growth in vivo by anti-angiogenetic and overall anti-tumor activities, independently by PI3K/AKT related pathways that at today is one of the more suggestive hypothesis to explain the anti-tumor effects of the different protease inhibitors. In summary these findings suggest novel anti-neoplastic action of Amprenavir on liver cancer showing the possibility of novel combination therapies.

Safety of fosamprenavir in a cohort of HIV-1-infected patients with co-morbidities.

BACKGROUND: The hypothesis that fosamprenavir-including highly active antiretroviral therapy (HAART) regimens would be associated with few metabolic and hepatic side-effects was investigated. PATIENTS AND METHODS: An observational single-arm retrospective study was set up on a cohort of 139 human immunodeficiency virus (HIV)-infected patients, followed up at A.O.R.N. Cotugno Hospital, Naples, Italy, treated with antiretroviral regimens including fosamprenavir, in order to evaluate the safety of these regimens in relationship to hepatic and metabolic side-effects, also considering co-morbidities and other risk factors. RESULTS: Only seven patients met the criteria to reach the primary end-point (grade ≥ 3 adverse event) and none of them discontinued HAART therapy during the follow-up period. Eighty percent of the patients reached viral load <50 cp/µl at 48 weeks of observation. At the end of follow-up, no patient with fasting serum total cholesterol and/or fasting serum triglycerides above grade 3 was found, while 1 out of 114 (0.88%) cases presented aspartate transaminase and alanine transaminase ≥ grade 3 and 1 out of 114 (0.88%) cases had fasting serum glucose ≥ grade 3. One out of 137 patients developed a malignant neoplasm (0.73%) and 4 (2.92%) displayed newly diagnosed hypertension. CONCLUSION: Fosamprenavir-based regimens caused a low number of serious metabolic adverse events during a 48 week follow-up period, with a low incidence of co-morbidities and satisfying results in terms of viro-immunological response including for patients with already existing co-morbidities requiring other therapies.

[Use of PCR for TB bacteria on BAL in early diagnosis of tubercular lobitis]. / PCR per BK su BAL nella diagnostica precoce di lobite tubercolare.

In June 2008 a 23-year-old immunocompetent came to our observation, without fever and with an occasional cough for 2 months, who showed two chest X-rays and a CT, performed respectively 60, 40 and 20 days earlier, that pointed to a small lobitis at the right lung base. The patient had already undergone several antibiotic therapies that had not changed the X-graphic framework. On presentation, routine blood tests and cultural examinations of sputum were carried out to detect common germs, fungi and TB bacteria (microscopic observation, cultivation and PCR), and a new antibiotic therapy (piperacillin/tazobactam) was started. Since the radiological picture appeared unchanged after 10 days of therapy and the examinations (microscopic observation and PCR) were negative, bronchoscopy with bacteriological evaluation of BAL was performed, which was positive to Mycobacterium tuberculosis, and then tubercular lobitis was diagnosed. Therefore a specific therapy - rifampin (RMP), isoniazid (INH), etambutol (EMB), pyrazinamid (PZA) - was started and changed after 10 days due to the growth of mycobacteria resistant to INH and EMB on examination of sputum. Consequently, the early use of PCR on BAL allows, in skilled hands, small aspecific lobitis to be diagnosed more rapidly than using cultural examination of sputum.
