Elevated Pancreatic Enzymes in ICU Patients With COVID-19 in Wuhan, China: A Retrospective Study

Acute pancreatitis as a complication of acute COVID-19 in kidney transplant recipients

BACKGROUND

Acute pancreatitis is a rare extrapulmonary manifestation of coronavirus disease 2019 (COVID-19) but its full correlation with COVID-19 infection remains unknown.

AIM

To identify acute pancreatitis' occurrence, clinical presentation and outcomes in a cohort of kidney transplant recipients with acute COVID-19.

METHODS

A retrospective observational single-centre cohort study from a transplant centre in Croatia for all adult renal transplant recipients with a functioning kidney allograft between March 2020 and August 2022 to record cases of acute pancreatitis during acute COVID-19. Data were obtained from hospital electronic medical records. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was proven by a positive SARS-CoV-2 real-time reverse transcriptase-polymerase chain reaction on the nasopharyngeal swab.

RESULTS

Four hundred and eight out of 1432 (28.49%) patients who received a renal allograft developed COVID-19 disease. The analyzed cohort included 321 patients (57% males). One hundred and fifty patients (46.7%) received at least one dose of the anti-SARS-CoV-2 vaccine before the infection. One hundred twenty-five (39.1%) patients required hospitalization, 141 (44.1%) developed pneumonia and four patients (1.3%) required mechanical ventilation. Treatment included immunosuppression modification in 233 patients (77.1%) and remdesivir in 53 patients (16.6%), besides the other supportive measures. In the study cohort, only one transplant recipient (0.3%) developed acute pancreatitis during acute COVID-19, presenting with abdominal pain and significantly elevated pancreatic enzymes. She survived without complications with a stable kidney allograft function.

CONCLUSION

Although rare, acute pancreatitis may complicate the course of acute COVID-19 in kidney transplant recipients. The mechanism of injury to the pancreas and its correlation with the severity of the COVID-19 infection in kidney transplant recipients warrants further research.

Investigation of factors affecting COVID-19 pancreatic injury: a single-center, retrospective study

Pancreatic injury is considered an organ-related complication in patients with coronavirus disease 2019 (COVID-19). However, it is unclear whether COVID-19 status affects pancreatic injury. This retrospective study aimed to determine whether COVID-19 affects the occurrence of pancreatic injuries. Consecutive patients diagnosed with sepsis admitted to the ICU between March 2020 and September 2021 were included. The primary endpoint was a pancreatic injury, which was defined as amylase or lipase levels > 3 times the upper limit of the normal range. Among the 177 patients included in the analysis, 40 (23%) were COVID-19 patients, and 54 (31%) had pancreatic injuries. Of these three patients, acute pancreatitis was diagnosed based on computed tomography. The pancreatic injury was significantly more common among COVID-19 patients (75 vs. 18%, p < 0.001). Multivariate analysis showed that COVID-19 and steroid use were independent risk factors for pancreatic injury (Odds Ratio (OR) 4.79 [95% confidence interval (CI) 1.48-15.5], p = 0.009; OR 4.02 [95% CI 1.42-11.4], p = 0.009). This study revealed that the proportion of pancreatic injury in septic patients with COVID-19 was significantly higher than in those without COVID-19. It may be difficult to diagnose pancreatitis based on amylase and lipase levels in COVID-19 patients.

The Pancreas in Coronavirus Disease 2019 Infection

An association between acute pancreatitis (AP) and coronavirus disease 2019 (COVID-19) has been proposed but the mechanisms of pancreatic injury of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and the implicative role on the development of AP are not yet fully understood. COVID-19 also imposed major challenges on pancreatic cancer management. We conducted an analysis on the mechanisms of pancreatic injury by SARS-CoV-2 and reviewed published case reports of AP attributed to COVID-19. We also examined the pandemic effect on pancreatic cancer diagnosis and management, including pancreatic surgery.

The burden of acute pancreatitis on COVID-19 in the United States

Background

Although SARS-CoV-2 primarily affects the respiratory system, gastrointestinal symptoms were also seen. Our study analyzed the prevalence and impact of acute pancreatitis (AP) on COVID-19 hospitalizations in the United States.

Methods

The 2020 National Inpatient Sample database was used to identify patients with COVID-19. The patients were stratified into 2 groups based on the presence of AP. AP as well as its impact on COVID-19 outcomes were evaluated. The primary outcome was in-hospital mortality. Secondary outcomes were intensive care unit (ICU) admissions, shock, acute kidney injury (AKI), sepsis, length of stay, and total hospitalization charges. Univariate and multivariate logistic/linear regression analyses were performed.

Results

The study population comprised 1,581,585 patients with COVID-19, from which 0.61% of people had AP. Patients with COVID-19 and AP had a higher incidence of sepsis, shock, ICU admissions, and AKI. On multivariate analysis, patients with AP had higher mortality (adjusted odds ratio [aOR] 1.19, 95% confidence interval [CI] 1.03-1.38; P=0.02). We also noted a higher risk of sepsis (aOR 1.22, 95%CI 1.01-1.48; P=0.04), shock (aOR 2.09, 95%CI 1.83-2.40; P<0.001), AKI (aOR 1.79, 95%CI 1.61-1.99; P<0.001), and ICU admissions (aOR 1.56, 95%CI 1.38-1.77; P<0.001). Patients with AP also had a longer length of stay (+2.03 days, 95%CI 1.45-2.60; P<0.001), and higher hospitalization charges ($44,088.41, 95%CI $33,198.41-54,978.41; P<0.001).

Conclusions

Our study revealed that the prevalence of AP in patients with COVID-19 was 0.61%. Although this was not strikingly high, the presence of AP is associated with worse outcomes and higher resource utilization.

SARS-CoV-2 and the pancreas: What do we know about acute pancreatitis in COVID-19 positive patients?

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause pancreatic damage, both directly to the pancreas via angiotensin-converting enzyme 2 receptors (the transmembrane proteins required for SARS-CoV-2 entry, which are highly expressed by pancreatic cells) and indirectly through locoregional vasculitis and thrombosis. Despite that, there is no clear evidence that SARS-CoV-2 is an etiological agent of acute pancreatitis. Acute pancreatitis in coronavirus disease 2019 (COVID-19) positive patients often recognizes biliary or alcoholic etiology. The prevalence of acute pancreatitis in COVID-19 positive patients is not exactly known. However, COVID-19 positive patients with acute pancreatitis have a higher mortality and an increased risk of intensive care unit admission and necrosis compared to COVID-19 negative patients. Acute respiratory distress syndrome is the most frequent cause of death in COVID-19 positive patients and concomitant acute pancreatitis. In this article, we reported recent evidence on the correlation between COVID-19 infection and acute pancreatitis.

Lipase elevation on admission predicts worse clinical outcomes in patients with COVID-19

BACKGROUND AND OBJECTIVES

Hyperlipasemia is highly prevalent among coronavirus disease 2019 (COVID-19) patients. The aim of this study was to assess the effect of lipase activity, measured at the time of admission, on the clinical course and mortality in COVID-19 patients.

METHODS

The population of this study comprised 12,139 patients who were hospitalized due to COVID-19 between June 2020 and June 2021 in a pandemic hospital. Of these, 8819 patients were excluded from the study due to missing data, four patients were excluded due to a diagnosis of acute pancreatitis (according to the revised Atlanta criteria), and 72 patients were excluded due to alcohol use or having a history of chronic pancreatitis. The final study sample consisted of the remaining 3244 COVID-19 patients. Laboratory results, intensive care unit (ICU) follow-up periods, the need for mechanical ventilation, and mortality rates were compared between the normal lipase activity and high lipase activity groups.

RESULTS

There were 968 (29.8%) patients with high lipase activity at the time of admission. The rate of ICU admission was 36.1% vs. 9.9% (p < 0.001), mechanical ventilation requirement rates were 33.7% vs. 8.3% (p < 0.001), and mortality rates were as 24.6% vs. 6.4% (p < 0.001) in the high lipase activity group compared to the normal lipase activity group. Multivariate regression analysis revealed that high lipase activity was an independent factor in predicting mortality in hospitalized COVID-19 patients (odds ratio [OR]: 3.191, p < 0.001).

CONCLUSION

Elevated lipase activity without acute pancreatitis at the time of admission in COVID-19 patients was determined as an independent predictor of poor prognosis.

Prevalence and Outcomes of Pancreatic Enzymes Elevation in Patients With COVID-19: A Meta-Analysis and Systematic Review

Background

Although coronavirus disease 2019 (COVID-19) is considered to be a disease that mainly involves the respiratory system, an increasing number of studies have reported that COVID-19 patients had pancreatic enzymes (PE) elevation and even pancreatic injury. The study aims to determine the prevalence of PE elevation, and the relationship between elevated PE and prognosis in COVID-19 patients.

Methods

A comprehensive literature search was conducted according to the PRISMA guideline in PubMed, Embase, Scopus, Web of Science, and Google Scholar for studies reporting PE elevation in patients with COVID-19 from 1st January 2020 to 24th November 2021.

Results

A total of 13 studies (24,353 participants) were included in our review. The pooled prevalence of PE elevation in COVID-19 patients was 24% (18%-31%), the pooled odds ratio (OR) of mortality was 2.5 (1.7-3.6), the pooled OR of ICU admission was 4.4 (2.8-6.8), and the pooled OR of kidney injury, respiratory failure and liver injury were 3.5 (1.6-7.4), 2.0 (0.5-8.7), and 2.3 (1.4-3.9) respectively. In addition, the subgroup analysis revealed that although PE elevated to > 3 × upper normal limit (ULN) was significantly related to the mortality (OR = 4.4, 2.1-9.4), it seemed that mild elevation of PE to 1-3 ULN also had a considerable risk of mortality (OR = 2.3, 1.5-3.5).

Conclusions

PE elevation was a common phenomenon in patients with COVID-19, and was associated with poor clinical outcomes. However, due to the limited numbers of included studies, the result of our study still needed to be validated.

Prevalence and prognosis of increased pancreatic enzymes in patients with COVID-19: A systematic review and meta-analysis

INTRODUCTION

The prevalence of increased pancreatic enzymes (elevated serum amylase and/or lipase) and its relationship to clinical outcomes in patients with coronavirus disease 2019 (COVID-19) infection is not known.

METHODS

A systematic review and meta-analysis of relevant studies reporting prevalence and impact of increased pancreatic enzymes (defined as an elevation in amylase and/or lipase levels above the upper limit of normal [ULN] value) in COVID-19 was undertaken.

RESULTS

A total of 36,496 patients from 21 studies were included for this meta-analysis. The overall prevalence and mortality for increased pancreatic enzymes (>ULN) in COVID-19 were 25.4% (95% CI, 15.8%-36.2%) and 34.6% (95% CI, 25.5%-44.4%), respectively. The overall prevalence and mortality for increased pancreatic enzymes (>3 × ULN) were 6.1% (95% CI, 3.6%-9.2%) and 39.2% (95% CI, 18.7%-61.6%), respectively. Patients with increased pancreatic enzymes, including elevated serum lipase or amylase of either type, had worse clinical outcomes, including need for ICU admission, mechanical ventilation and mortality.

DISCUSSION

Increased pancreatic enzymes is frequent and may exacerbate the consequences of COVID-19 infection.

Single-Cell Transcriptome Analysis Reveals the Role of Pancreatic Secretome in COVID-19 Associated Multi-organ Dysfunctions

The SARS-CoV-2 infection affects the lungs, heart, kidney, intestine, olfactory epithelia, liver, and pancreas and brings forward multi-organ dysfunctions (MODs). However, mechanistic details of SARS-CoV-2-induced MODs are unclear. Here, we have investigated the role of pancreatic secretory proteins to mechanistically link COVID-19 with MODs using single-cell transcriptome analysis. Secretory proteins were identified using the Human Protein Atlas. Gene ontology, pathway, and disease enrichment analyses were used to highlight the role of upregulated pancreatic secretory proteins (secretome). We show that SARS-CoV-2 infection shifts the expression profile of pancreatic endocrine cells to acinar and ductal cell-specific profiles, resulting in increased expression of acinar and ductal cell-specific genes. Among all the secretory proteins, the upregulated expression of IL1B, AGT, ALB, SPP1, CRP, SERPINA1, C3, TFRC, TNFSF10, and MIF was mainly associated with disease of diverse organs. Extensive literature and experimental evidence are used to validate the association of the upregulated pancreatic secretome with the coagulation cascade, complement activation, renin-angiotensinogen system dysregulation, endothelial cell injury and thrombosis, immune system dysregulation, and fibrosis. Our finding suggests the influence of an upregulated secretome on multi-organ systems such as nervous, cardiovascular, immune, digestive, and urogenital systems. Our study provides evidence that an upregulated pancreatic secretome is a possible cause of SARS-CoV-2-induced MODs. This finding may have a significant impact on the clinical setting regarding the prevention of SARS-CoV-2-induced MODs.

Pancreatic Injury in Patients with SARS-Cov-2 (COVID-19) Infection: A Retrospective Analysis of CT Findings

Objective

To determine the association between COVID-19 infection and peripancreatic changes on CT as a sign of acute pancreatic injury.

Methods

Retrospective analysis of CT examinations in patients with confirmed COVID-19 infection yielded 103 instances. An age- and gender-matched cohort of patients without COVID-19 was found. CT examinations were evaluated for peripancreatic stranding or edema, fluid collection, or necrosis, without any other explanation. Depicted pulmonary parenchyma was evaluated for possible COVID-19-related changes. Clinical and laboratory data were retrieved from the clinical database.

Results

Peripancreatic fat stranding (n = 8) or fluid collection (n = 2) without any other cause was found in 10 (10%) patients. Abdominal complaints were reported in 4 (40%) patients. Elevated serum amylase or lipase levels were documented in 5 (50%) patients who also satisfied the diagnostic criteria for acute pancreatitis. From the study sample of 103 patients with COVID-19, pulmonary parenchyma was depicted in 102 (99%), and from these, 57 (55%) had an evidence of pulmonary changes compatible with COVID-19 pneumonia. This proportion was not significantly different between patients with and without peripancreatic changes (p = 0.35). In the matched cohort, we found peripancreatic changes in 2 (2%, p = 0.033) patients. Patients with pancreatic injury and elevated amylase levels were more likely to require orotracheal intubation (35% vs. 12%, p = 0.021).

Conclusions

We showed that the prevalence of peripancreatic stranding or fluid collection is higher in patients diagnosed with COVID-19 infection compared to an age- and gender-matched cohort. Patients with pancreatic injury and elevated amylase levels are more likely to require orotracheal intubation. Our findings corroborate the link between COVID-19 infection and pancreatic injury from the perspective of imaging.
