Abstract

Preliminary evidence supports the notion that COVID-19 patients may have an increased susceptibility to develop venous thromboembolism (VTE). However, the magnitude of this association still needs to be defined. Furthermore, clinical predictors of thrombogenesis, and the relationship with the inflammatory status are currently unknown. On this basis, we conducted a retrospective, observational study on 259 consecutive COVID-19 patients admitted to an academic tertiary referral hospital in Northern Italy between March 19th and April 6th, 2020. Records of COVID-19 patients with a definite VTE event were reviewed for demographic information, co-morbidities, risk factors for VTE, laboratory tests, and anticoagulation treatment. Twenty-five cases among 259 COVID-19 patients developed VTE (9.6%), all of them having a Padua score > 4, although being under standard anticoagulation prophylaxis since hospital admission. In the VTE subcohort, we found a significant positive correlation between platelet count (PLT) and either C reactive protein (CRP) (p p = 0.0013), while a significant inverse correlation was observed between PLT and mean platelet volume (p p p = 0.002 and p = 0.005, respectively). No significant difference was found in d-dimer levels between VTE and non VTE patients, while significantly higher levels of LDH (p = 0.04) and IL-6 (p = 0.04) were observed in VTE patients in comparison to non-VTE patients. In conclusion, our findings showed a quite high prevalence of VTE in COVID-19 patients. Raised inflammatory indexes and increased serum levels of pro-inflammatory cytokines should raise the clinical suspicion of VTE.

Abstract

The clinical manifestation of COVID-19 can vary from an asymptomatic course to ARDS requiring invasive mechanical ventilation and extracorporeal membrane oxygenation. A kidney transplanted patient infected with SARS CoV-2 infection showed a mild disease despite immune suppression. It is possible that Immunosuppression can "be protective" as the cytokine storm is an important factor in the disease story. Despite the good outcome reported in the present case report, is remains of vital importance the solid organ transplant patients use precautions in order to avoid the infection.

Abstract

Olfactory and taste disorders (OTD) are commonly found as presenting symptoms of SARS-CoV-2 infection in patients with clinically mild COVID-19. Virus-specific T cells are thought to play an important role in the clearance of SARS-CoV-2; therefore the study of T cell specific immune responses in patients with mild symptoms may help to understand their possible role in protection from severe disease. We evaluated SARS-CoV-2-specific T cell responses to four different peptide megapools covering all SARS-CoV-2 proteins during the acute phase of the disease in 33 individuals with mild or no other symptom beside OTD and in 22 age-matched patients with severe infection. A control group of 15 outpatients with OTD and consistently negative nasopharyngeal SARS-CoV-2 RNA swabs and virus-specific IgG serology was included in the study. Increased frequencies of virus-specific CD4+ and CD8+ T cells were found in SARS-CoV-2 positive patients with OTD compared with those with severe COVID-19 and with SARS-CoV-2 negative OTD individuals. Moreover, enhanced CD4+ and CD8+ T-cell activation induced by SARS-CoV-2 peptides was associated with higher interferon (IFN)γ production. Increased frequencies of Spike (S1/S2)-specific CD4+ T cells showing enhanced IFNγ secretion and granzyme B content were associated with serum spike-specific IgG in the OTD group. In conclusion, patients with SARS-CoV-2 induced OTD develop highly functional virus-specific CD4+ and CD8+ T cells during the symptomatic phase of the disease, suggesting that robust and coordinated T-cell responses provide protection against extension of COVID-19 to the lower respiratory tract.

Abstract

SARS-CoV-2 and flu may lead to severe acute respiratory distress syndrome (ARDS) requiring extracorporeal membrane oxygenation (ECMO). The aim of the present study is to compare the incidence of bloodstream infections (BSIs) and outcome in patients with flu and SARS-CoV-2 infection hospitalized in ICU and undergoing ECMO. This study is a retrospective analysis of the San Matteo COVID-19 Registry (SMACORE) cohort. The study was conducted from January 2018 to April 2020. Demographic data and microbiological data were recorded during hospitalization. BSIs occurring during ECMO were analyzed. Eighteen patients treated with ECMO, 22 subjects with SARS-CoV-2 infection and 7 with flu, median age 61years for SARS-CoV-2 and 50 for flu (p=NS). Median ECMO duration was similar in the two pathologies. Median time to bloodstream infection from ECMO initiation was similar. Bloodstream infection incidence rate was 2.65 per 100 patients/days for flu and 2.2 per 100 patients/days for SARS-CoV-2. Global infection rate was 5 per 100 patients/days for SARS-CoV-2 patients and 5.3 per 100 patients/days for flu. Mortality during ECMO was 40.9% (5 out of 22 patients) for SARS-CoV-2 infection while none died among flu patients. ECMO-associated mortality was higher in SARS-CoV-2 infection compared with flu infection.

Abstract

The COVID-19 pandemic is posing an unprecedented threat worldwide. One issue that has faltered, though, concerns the underestimated risk to trade all for COVID-19, misdiagnosing other potentially life-threatening diseases. Further still, the presence of respiratory symptoms in AIDS patients should stimulate more vigilant efforts to uncover other or additional infections. This case report highlights the pitfalls of diagnosing a rare pulmonary infection during the COVID-19 pandemic.
