ACP risk grade: a simple mortality index for patients with confirmed or suspected severe acute respiratory syndrome coronavirus 2 disease (COVID-19) during the early stage of outbreak in Wuhan, China

BackgroundSince the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease (COVID-19) outbreaks in Wuhan, China, healthcare systems capacities in highly endemic areas have been overwhelmed. Approaches to efficient management are urgently needed and key to a quicker control of the outbreaks and casualties. We aimed to characterize the clinical features of hospitalized patients with confirmed or suspected COVID-19, and develop a mortality risk index for COVID-19 patients. MethodsIn this retrospective one-centre cohort study, we included all the confirmed or suspected COVID-19 patients hospitalized in a COVID-19-designated hospital from January 21 to February 5, 2020. Demographic, clinical, laboratory, radiological and clinical outcome data were collected from the hospital information system, nursing records and laboratory reports. ResultsOf 577 patients with at least one post-admission evaluation, the median age was 55 years (interquartile range [IQR], 39 - 66); 254 (44.0%) were men; 22.8% (100/438) were severe pneumonia on admission, and 37.7% (75/199) patients were SARS-CoV-2 positive. The clinical, laboratory and radiological data were comparable between positive and negative SARS-CoV-2 patients. During a median follow-up of 8.4 days (IQR, 5.8 - 12.0), 39 patients died with a 12-day cumulative mortality of 8.7% (95% CI, 5.9% to 11.5%). A simple mortality risk index (called ACP index), composed of Age and C-reactive Protein, was developed. By applying the ACP index, patients were categorized into three grades. The 12-day cumulative mortality in grade three (age [≥] 60 years and CRP [≥] 34 mg/L) was 33.2% (95% CI, 19.8% to 44.3%), which was significantly higher than those of grade two (age [≥] 60 years and CRP < 34 mg/L; age < 60 years and CRP [≥] 34 mg/L; 5.6% [95% CI, 0 to 11.3%]) and grade one (age < 60 years and CRP < 34 mg/L, 0%) (P <0.001), respectively. ConclusionThe ACP index can predict COVID-19 related short-term mortality, which may be a useful and convenient tool for quickly establishing a COVID-19 hierarchical management system that can greatly reduce the medical burden and therefore mortality in highly endemic areas.

Effect of FOLFOX6 chemotherapy on serum VEGF expression in advanced colorectal cancer patients.

OBJECTIVE: To explore the effect of FOLFOX6 chemotherapy on serum vascular endothelial growth factor (VEGF) expression in advanced colorectal cancer patients. METHODS: A retrospective analysis of 81 patients with advanced colorectal cancer who visited our hospital from March 2014 to February 2016 was performed. All the patients were treated with FOLFOX6 chemotherapy. On day 1, patients received oxaliplatin 100 mg/m2 ivgtt (2h), calcium folinate 200 mg/m2 ivgtt (2h), 5 fluorouracil 400 mg/m2 iv bolus and 5 fluorouracil 2500 mg/m2 ivgtt (5h). The treatment course was 2 weeks, and 4 treatment courses were required. The changes in the levels of VEGF and CRP and quality of life before and after 4 courses of chemotherapy were observed and therapeutic effects and adverse reactions after chemotherapy were evaluated. RESULTS: After treatment, the total efficiency of chemotherapy was 82.72% (67/81) with 24 cases in complete remission, 25 cases in partial response, 18 cases in stable disease and 14 cases in progressive disease. The levels of CRP and VEGF after the treatment were significantly lower than those before treatment (5.69±0.77) mg/L vs. (7.99±1.36) mg/L; (443.26±21.55) pg/mL vs. (542.83±20.44) pg/mL] (P<0.05). The KPS grade after treatment was significantly higher than that before treatment (57.84±4.6) point vs. (50.99±3.73) point] (P<0.05). Among them, 3 cases developed a rash, 5 cases experienced hair loss, and 9 cases developed nausea and vomiting. CONCLUSION: FOLFOX6 chemotherapy can decrease serum VEGF expression in patients with advanced colorectal cancer and enhance the curative effect with high safety, which is good for the improvement of patients' survival.

RESUMO OBJETIVO: Explorar o efeito da quimioterapia Folfox6 na expressão do fator de crescimento endotelial vascular sérico (VEGF) em pacientes com câncer colorretal avançado. MÉTODOS: Uma análise retrospectiva de 81 pacientes com câncer colorretal avançado que visitaram nosso hospital de março de 2014 a fevereiro de 2016 foi realizada. Todos os pacientes foram tratados com quimioterapia Folfox6. No dia 1, os doentes receberam oxaliplatina 100 mg / m2 ivgtt (2h), folinato de cálcio 200 mg/m2 ivgtt (2h), 5 fluorouracil 400 mg/m2 iv bolus e 5 fluorouracil 2.500 mg/m2 ivgtt (5h). O curso de tratamento foi de duas semanas e foram necessários quatro cursos de tratamento. Foram observadas as alterações nos níveis de VEGF e CRP e qualidade de vida antes e após quatro cursos de quimioterapia e avaliados os efeitos terapêuticos e reações adversas após a quimioterapia. RESULTADOS: Após o tratamento, a eficácia total da quimioterapia foi de 82,72% (67/81), com 24 casos em remissão completa, 25 casos em resposta parcial, 18 casos em doença estável e 14 casos em doença progressiva. Os níveis de CRP e VEGF após o tratamento foram significativamente inferiores aos do tratamento (5,69 ± 0,77) mg / L vs. (7,99 ± 1,36) mg / L; (443,26 ± 21,55) pg / mL vs. (542,83 ± 20,44) pg / mL] (P < 0,05). O grau de KPS após o tratamento foi significativamente maior do que antes do tratamento (57,84 ± 4,6 pontos) vs. (50,99 ± 3,73 pontos)] (P < 0,05). Entre eles, três casos desenvolveram erupção cutânea, cinco casos sofreram perda de cabelo e nove casos desenvolveram náuseas e vômitos. CONCLUSÃO: A quimioterapia Folfox6 pode, obviamente, diminuir a expressão de VEGF no soro em pacientes com câncer colorretal avançado e melhorar o efeito curativo com alta segurança, o que é bom para a melhoria da sobrevivência dos pacientes.
