Coronavirus disease-19 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV- 2) and has resulted in increased mortality worldwide. Several studies have identified the involvement of the gastrointestinal tract, respiratory tract, and other tissues. Although it has been reported that the angiotensin-converting enzyme-2 receptor affected by SARS-CoV is expressed more in the pancreas than in the lungs, the issue regarding the occurrence of pancreatitis is controversial. SARS Cov-2 rarely causes acute necrotizing pancreatitis without significantly affecting the respiratory and other systems. This paper presents a patient who underwent laparotomy due to acute necrotizing pancreatitis and hemodynamic instability caused by COVID-19 without any known risk factors.

Purpose:
The purpose of our study was initially to explore the prognostic role of LDH-to-albumin ratio in patients with colorectal carcinoma (CRC) undergoing curative resection.
Methods:
The retrospective study included 295 CRC patients that underwent curative resection. According to timedependent receiver operating characteristics (ROC) analysis, the optimal cutoff value for pretreatment LDH-to-albumin ratio was 52.7. Cox regression univariate and multivariate analyses were utilized to analyze the prognostic factors for disease-free survival (DFS) and overall survival (OS).
Results:
The 295 participants included 117 women (39.7%) and had an overall mean age of 55.8 ± 14.1 years. The median follow-up period was 31.8 ± 21 months (range, 6–78 months) and 53 patients (18.0%) died from cancer during the followup period. The 5-year DFS and OS rates were 65.4% and 68.5% in patients with LDH-to-albumin ratio <52.7 (n = 152), and were 55.2% and 55.4% in patients with LDH-to-albumin ratio ≥52.7 (n = 143), respectively. Kaplan-Meier curves showed that LDH-to-albumin ratio ≥52.7 was significantly associated with worse DFS and OS (p = 0.003 and p < 0.001, respectively). Multivariate analyses revealed that LDH-to-albumin ratio was an independent predictor of resectable CRC (odds ratio, 2.104; 95% confidence interval, 1.112–3.982; p = 0.022).
Conclusion
Our study revealed that high pretreatment LDH-to-albumin ratio level was an unfavorable prognosticator in patients with CRC undergoing curative resection. LDH-to-albumin ratio is a candidate to be a prognostic biomarker in clinical practice.
