    SARS-CoV-2 leading to acute pancreatitis: an unusual presentation
    (2020) ALVES, Amanda Mandarino; YVAMOTO, Erika Yuki; MARZINOTTO, Maira Andrade Nacimbem; TEIXEIRA, Ana Cristina de Sa; CARRILHO, Flair Jose
    During SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) pandemic, the etiologic agent of COVID-19, several studies described the involvement of other tissues besides the respiratory tract, such as the gastrointestinal tract. Angiotensin-converting enzyme-2, the functional virus host cell receptor expressed by organs and tissues, seems to have an important role in the pathophysiology and presentation of this disease. In pancreas, this receptor is expressed in both exocrine glands and islets, being a potential target for the virus and subsequent pancreatic injury. There are few articles reporting pancreatic injury in COVID-19 patients but most of them do not report acute pancreatitis. Diagnosing acute pancreatitis secondary to SARS-CoV-2 infection is challenging due to the need to rule out other etiologies as well the notable heterogeneous presentations. Herein we report the case of a patient with COVID-19 who developed severe acute pancreatitis. (C) 2020 Sociedade Brasileira de Infectologia.

    Frequency of Tabagism and N34S and P55S Mutations of Serine Peptidase Inhibitor, Kazal Type 1 (SPINK1) and R254W Mutation of Chymotrypsin C (CTRC) in Patients With Chronic Pancreatitis and Controls

    Objective: This study aimed to investigate the association between chronic pancreatitis and smoking or genetic mutations. Methods: The study sample comprised 148 patients with chronic pancreatitis, 110 chronic alcoholic subjects without pancreatic disease, and 297 volunteer blood donors. Results: Of the patients with chronic pancreatitis, 74% had alcoholic etiology and 26% had idiopathic pancreatitis. The frequency of smoking was 91.4% in patients with alcoholic pancreatitis, higher than 73.3% in alcoholic subjects without pancreatitis (P < 0.01). The difference in smoking frequency was not significant between the patients with idiopathic pancreatitis and blood donors. The N34S mutation of serine peptidase inhibitor, Kazal type 1 (SPINK1) was found in 2.7% of patients with chronic alcoholic pancreatitis, in 5.3% of patients with idiopathic pancreatitis, and in 0.4% of blood donors (P = 0.02). The P55S mutation of SPINK1 was found in 2.7% of patients with alcoholic pancreatitis and in 0.7% of blood donors (P = 0.12). The R254W mutation of chymotrypsin C was found in 0.9% of patients with alcoholic pancreatitis, in 0.9% of chronic alcoholic subjects without pancreatitis, and in 0.4% of blood donors (P = 0.75). In all cases, the mutations were heterozygous. Conclusions: Smoking and the N34S mutation of SPINK1 were positively correlated with chronic pancreatitis.
