ABSTRACT
Objectives: Cases of fulminant myocarditis after mRNA COVID-19 vaccination have been reported. The most severe may need venoarterial extracorporeal membrane oxygenation (V-A ECMO) support. Here we report two cases successfully rescued with V-A ECMO. Method(s): We included all the cases supported with V-A ECMO for refractory cardiogenic shock due to myocarditis secondary to a mRNA SARS-COV2 vaccine in the high-volume adult ECMO Program in Vall Hebron University Hospital since January 2020. Result(s): We identified two cases (table). One of them was admitted for out-of-hospital cardiac arrest. In both, a peripheral V-A ECMO was implanted in the cath lab. An intra-aortic balloon pump was needed in one case for left ventricle unloading. Support could be successfully withdrawn in a mean of five days. No major bleeding or thrombosis complications occurred. Definite microscopic diagnosis could be reached in one case (Image, 3). Treatment was the same, using 1000mg of methylprednisolone/day for 3 days. A cardiac magnetic resonance 10 days after admission showed a significant improvement in systolic function and diffuse oedema and subepicardial contrast intake in different segments (Image, 1-2). Both patients were discharged fully recovered. Conclusion(s): V-A ECMO should be established in cases of COVID-19 vaccine-associated myocarditis with refractory cardiogenic shock during the acute phase. (Table Presented).
ABSTRACT
COVID-19 will mark a before and after. Moreover, events are occurring that will tend to lessen the significance of the pandemic, to place it as a health event of extraordinary importance. Events such as the rearrangement of existing empires in search of new balances;generalized social explosion;possible regressive trajectories in world democratization;populist-nationalist movements that are highly dangerous for democracies;intensification of ecological refugee flows and phenomena such as climate change, which is unnerving public opinion, are just some of the current macro-trends. With specific reference to the post-pandemic period, there are facts that should be investigated: Why, for several decades, have the countries of the region allocated to their health services a lower percentage investment than those considered appropriate by the World Health Organization (WHO) or the practical non-existence of acceptable social security systems? Why has the democratizing wave that has benefited the region underestimated public health as an important item to improve the quality of life? Regarding the economic devastation caused by the pandemic, experts have dared to say that it will take one to two decades to return to normality, especially in the labor market, where millions of workers have been made redundant and profound changes are expected in the modalities and ways of working, leading to a reduction in employment opportunities. Education, fundamental to continuing future progress, will emerge from the pandemic subject to a major overhaul. After the pandemic, there will be a demand for more resources to be allocated to scientific research on infectious diseases;one field that will surely be strengthened will be that of ecology. I am convinced that the pandemic has served to strengthen the paradigm of sustainable development;that which harmonizes economic, social, political, and ecological sustainability. © Gac Méd Caracas 2022.

ABSTRACT
BACKGROUND: COVID-19 infection manifests as pneumonia associated with multiple organ failure, and death. Acute kidney injury is a risk factor for mortality. There is limited scientific literature on COVID-19 infection and allergic tubulointerstitial nephritis, its clinical course and short- and long-term prognosis. METHOD: We performed a retrospective study where medical records of 60 patients with histological diagnosis of allergic tubulointerstitial nephritis from January 2009 to November 2020. In these patients, we studied the incidence of COVID-19 infection, clinical characteristics and prognosis from March to the actual date. RESULTS: Of 60 patients with allergic tubulointerstitial nephritis, 6 (10%) patients were diagnosed with COVID-19. The first case, an 85-year-old woman with a history of metastatic melanoma treated with nivolumab and allergic tubulointerstitial nephritis by immunobiological agents in 2018, diagnosed with mild COVID-19 infection in April 2020 without deterioration of renal function in controls at 3 and 6 months of follow-up. The second case, a 51-year-old woman with a history of large B-cell lymphoma with plasmacytic differentiation and progression to multiple myeloma of lambda light chains and allergic tubulointerstitial nephritis due to chemotherapy since 2019, admitted for acute pyelonephritis and PRES syndrome secondary to first dose of bortezomib complicated with COVID-19 nosocomial pneumonia and acute pancreatitis treated with corticosteroids and broad spectrum antibiotic therapy;she died of abdominal refractory septic shock. The third patient, a 64-year-old man without prior renal impairment, was admitted for severe COVID-19 pneumonia and acute kidney injury secondary to acute tubulointerstitial nephritis of uncertain etiology that required orotracheal intubation and continuous veno-venous hemodiafiltration for a week who received methylprednisolone in bolus for 3 days and continued treatment with corticosteroid therapy with complete recovery of renal function and improvement in proteinuria at 3 months of follow-up. The fourth patient, an 82-yearold woman with acute kidney injury AKIN 3 secondary to acute allergic tubulointerstitial nephritis related to ciprofloxacin complicated with severe COVID-19 nosocomial pneumonia, who died despite ventilatory support and high-dose steroids therapy and tocilizumab. The fifth patient, a 75-year-old with a history of metastatic lung adenocarcinoma treated with immunobiological agents and allergic tubulointerstitial nephritis in 2018, admitted in march 2020 for mild COVID-19 pneumonia treated with steroids and hydroxychloroquine without deterioration of respiratory and kidney function. The sixth patient, an 86-years-old man with acute kidney injury AKIN 3 due to acute allergic tubulointerstitial nephritis secondary to proton-binding inhibitors and nosocomial COVID-19 infección with improvement of kidney function with steroids therapy only. CONCLUSION: Our 6 patients with allergic tubulointerstitial nephritis and COVID-19 infection presented different spectrum of the disease. It seems that nosocomial COVID-19 infection in patients admitted with recent diagnosis of acute allergic tubulointerstitial nephritis presented a worse clinical prognosis compared with long-term diagnosed acute tubulointerstitial nephritis. Further studies with a larger sample size are needed.
ABSTRACT
BACKGROUND AND AIMS: COVID-19 infection is responsible for respiratory infection with variable clinical expression from its asymptomatic form to severe pneumonia associated with acute respiratory distress syndrome and death. Risk factors related to higher mortality are age over 65 years, cardiovascular, pulmonary and kidney disease, hypertension, and diabetes. There is limited scientific literature on COVID-19 infection and previous kidney disease, specifically in patients with glomerular and tubular kidney disease. The aim of this study was to determine general characteristics, analytical parameters and clinical evolution of patients with kidney disease who have undergone kidney biopsy and who presented infection or high suspicion of infection by COVID-19. Identify mortality and associated risk factors. METHOD: we studied patients with high clinical suspicion of infection or confirmed infection by COVID-19 from March 2020 to May 15, 2020 of all patients who underwent percutaneous renal biopsy at the Vall d'Hebron Hospital between January 2013 and December 2019. RESULTS: 39 of the 553 patients have been diagnosed with COVID-19 infection since March 2020. The average age was 63615 years and 48.7% were male. Hypertension was present in 79.5% of patients, chronic kidney disease without renal replacement therapy in 76.9%, and cardiovascular disease in 64.1%. Nasopharyngeal swab was performed in 26 patients;older patients (p=0.01), patients with hypertension (p=0.005), immunosuppression (p=0.01), use of RAS-blocking drugs (p=0.04) and gastrointestinal symptoms (p=0.02) were more likely to be tested for COVID-19. 22 patients required hospitalization and 15.4% died. In the bivariate analysis, mortality was associated with older age (p=0.03), cardiovascular disease (p=0.05), chronic obstructive pulmonary disease (COPD) (p=0.05) and low hemoglobin levels (p=0.006). Adjusted Cox regression showed that low hemoglobin levels (10.12±1.89g/dL) at admission had 1.81 greater risk of mortality [1.04-3.13;p=0.04]. CONCLUSION: Patients with COVID-19 infection and kidney disease confirmed by kidney biopsy presented mortality of 15.4%. Swab test for COVID-19 was more likely to be performed in older, hypertensive, use of RAS-blocking drugs, immunosuppressed patients and those with gastrointestinal symptoms. Low hemoglobin is a risk factor for mortality.
