RESUMO
Cancer patients are exposed to more complications from COVID-19 than non-cancer patients. We report a cohort of 74 cancer patients (87.8% with solid neoplasia and 12.2% with hematological diseases) with COVID-19 infection admitted to a tertiary medical cancer center in Argentina. Pulmonary infiltrates were diagnosed at admission in 78.3% (N = 58) of the cases. COVID-19 infection was hospital-acquired in 20 (27.0%) patients. Thirty-nine patients (52.7%) received anticancer therapy within the 30 days prior to COVID-19 diagnosis; one was on radiation therapy. Twenty-four (32.4%) patients were admitted in the intensive care unit (ICU) and 18 (75.0%) required mechanical ventilation. All cause in-hospital mortality was 32.4% (N = 24) and ICU mortality was 62.5% (N = 15). Mortality under mechanical ventilation was 72.2% (N = 13). In the univariate analysis age, neutrophil count, neutrophil/lymphocyte index, D-dimer, ferritin, smoking, and nosocomial acquired infection were associated with in-hospital mortality. There were no statistically significant differences in mortality related to disease stage for solid tumors, neither cancer treatment within 30 days of COVID-19 diagnosis. Age and smoking were associated with mortality in the multivariate analysis. The adjusted odds ratios (95 CI) for age = 65 years and smoking were 8.87 (1.35-58.02) and 8.64 (1.32 - 56.64), respectively. Our experience can be useful for other institutions that assist cancer patients during the pandemic.
Los pacientes con cáncer y COVID-19 tienen más complicaciones que la población general. Comunicamos una cohorte de 74 pacientes con cáncer y COVID-19 internados en una institución oncológica. El 87.8% tenía diagnóstico de tumores sólidos y 12.2% oncohematológicos. Entre los tumores sólidos, el 61.5% presentó enfermedad metastásica. El 78.3% (N = 58) tenía infiltrados pulmonares al diagnóstico de COVID-19. La infección fue intrahospitalaria en 20 pacientes. Habían recibido tratamiento antineoplásico dentro de los 30 días anteriores al diagnóstico 39 pacientes (52.7%); uno se encontraba recibiendo radioterapia. Veinticuatro pacientes (32.4%) se derivaron a terapia intensiva (UTI) y 18 (75%) de ellos requirieron asistencia respiratoria mecánica (ARM). La mortalidad general durante la internación fue 32.4% (N = 24). La mortalidad en UTI fue 62.5% (N = 15). La mortalidad en ARM fue 72.2% (N = 13). La edad, recuento de neutrófilos, índice neutrófilo/linfocito, dímero D, ferritina, tabaquismo y haber adquirido la infección durante la internación resultaron estadísticamente significativos en el análisis univariado para mortalidad. No hallamos diferencias en mortalidad por estadio de enfermedad, en los pacientes con tumores sólidos, ni por haber recibido tratamiento antineoplásico dentro de los 30 días del diagnóstico de COVID-19. En el análisis multivariado con el modelo de regresión logística, solo la edad y el tabaquismo fueron predictores de mortalidad. Los odds ratios (IC 95) ajustados para la edad =65 años y el tabaquismo fueron 8.87 (1.35-58.02) y 8.64 (1.32-56.64), respectivamente. Este trabajo puede resultar de utilidad para instituciones polivalentes que asistan pacientes oncológicos durante la pandemia.

OBJECTIVE: We examined whether PEEP during the first hours of ARDS can induce such a change in oxygenation that could mask fulfillment of the AECC criteria of a PaO(2)/FIO(2) = 200 essential for ARDS diagnosis. DESIGN AND SETTING: Observational, prospective cohort in two medical-surgical ICU in teaching hospitals. PATIENTS: 48 consecutive patients who met AECC criteria of ARDS on 0 PEEP (ZEEP) at the moment of diagnosis. MEASUREMENTS AND RESULTS: PaO(2)/FIO(2) and lung mechanics were recorded on admission (0 h) to the ICU on ZEEP, and after 6, 12, and 24 h on PEEP levels selected by attending physicians. Lung Injury Score (LIS) was calculated at 0 and 24 h. PaO(2)/FIO(2) rose significantly from 121+/-45 on ZEEP at 0 h, to 234+/-85 on PEEP of 12.8+/-3.7 cmH(2)O after 24 h. LIS did not change significantly (2.34+/-0.53 vs. 2.42+/-0.62). These variables behaved similarly in pulmonary and extrapulmonary ARDS, and in survivors and nonsurvivors. After 24 h only 18 patients (38%) still had a PaO(2)/FIO(2) of 200 or lower. Their mortality was similar to that in the remaining patients (61% vs. 53%). CONCLUSIONS: The use of PEEP improved oxygenation such that one-half of patients after 6 h, and most after 24 h did not fulfill AECC hypoxemia criteria of ARDS. However, LIS remained stable in the overall series. These results suggest that PEEP level should be taken into consideration for ARDS diagnosis.
