February 2021—SARS-CoV-2 primarily causes pulmonary injury, but it has been implicated in hepatic injury through the use of serum markers and histologic evaluation. The histologic pattern of injury has not been completely described, and studies quantifying viral load in the liver are lacking. The authors conducted a study in which they reported the clinical and histologic findings related to the liver in 40 patients who died of complications of COVID-19. For the study, they subjected a subset of liver tissue blocks to polymerase chain reaction (PCR) for viral RNA. Peak levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated, with a median ALT peak of 68 U/L (normal up to 46 U/L) and median AST peak of 102 U/L (normal up to 37 U/L). Macrovesicular steatosis was the most common finding, involving 30 (75 percent) patients.

Molecular pathology selected abstracts

February 2021—Beta-thalassemia and sickle cell disease are common hereditary conditions that can have life-threatening complications. Both diseases are caused by genetic alterations affecting the beta subunit of hemoglobin. Mutations that reduce or prevent the synthesis of the beta-globin protein cause beta-thalassemia, a disease characterized by inadequate red blood cell production and, therefore, anemia. In contrast, sickle cell anemia results from a specific point mutation in the beta-globin gene that causes the resulting protein to polymerize. These protein polymers form rigid fibers that affect the stability of the red blood cell and cause its characteristic sickling deformity. Destruction of the aberrant red blood cells leads to anemia, and the sickled cells can also cause painful vaso-occlusive episodes and tissue damage.

Q&A column

Q.
 Can toxicology testing be performed on a person who has been deceased for two years? Read answer.
Q. Is there a standardized procedure for performing platelet estimates that incorporates the dilution effect for low hemoglobin in anemic patients? The formula I found for platelet estimation works well with low hemoglobin levels but not with levels greater than 13 g/dL. Read answer.

From the President’s Desk: Celebrating 75 years

January 2021—Please join me in a collective sigh of relief: 2020 is finally over. I am glad that awful year is behind us at last and sincerely hope that 2021 will be kinder and gentler to us all. From my perspective, 2021 is already off to a better start because it gives us a reason to celebrate. In 1946, 140 board-certified pathologists gathered in Chicago on Dec. 12 and 13 and formed the College of American Pathologists. This year is our 75th anniversary.

Clinical pathology selected abstracts

January 2021—Annual expenditures for clinical laboratory testing account for approximately $71.6 billion of health care costs and represent about 2.4 percent of all health care spending. While laboratory testing is critical, recommendations of the Choosing Wisely initiative focus on reducing laboratory costs and unnecessary testing, in part through dialogue between physicians and patients. Specialty societies widely accept and participate in Choosing Wisely recommendations, but outcomes of the initiative are largely unknown. The American Society for Clinical Pathology put forth 25 recommendations for Choosing Wisely, of which the 13th recommendation stated that serum lipase is the preferred test for diagnosing acute pancreatitis because lipase peaks by 24 hours and remains elevated for eight to 14 days. It was also recommended that serum amylase tests not be ordered with serum lipase tests because one or the other is sufficient for the diagnosis.

January 2021—The authors conducted a review of postmortem pulmonary histopathologic findings of COVID-19 pneumonia in patients who had a spectrum of disease course that ranged from rapid demise to prolonged hospitalization. They analyzed histopathologic findings in postmortem lung tissue from eight patients who died from COVID-19 pneumonia. Immunohistochemistry and next-generation sequencing (NGS) were used to detect the virus. Diffuse alveolar damage (DAD) was seen in all cases with a spectrum of acute phase or organizing phase, or both. IHC with monoclonal antibodies against SARS-CoV-2 viral nucleoprotein and spike protein detected virus in areas of acute but not organizing DAD.

Molecular pathology selected abstracts

January 2021—Circular RNAs are a novel class of recently discovered RNA with emerging roles in gene regulation, homeostasis, and disease. They are generated by ligation of the distal ends to form a circular product and originate from parental-coding genes and noncoding regions of the genome. Circular RNAs (circRNAs) are widespread in the plant and animal kingdoms and conserved in multiple species. Recent literature suggests that they inhibit micro RNA (mi­RNA), an important class of RNAs that regulates gene expression by binding to messenger RNAs (mRNA). Therefore, the post-transcriptional regulation of gene expression by RNAs has expanded to include a circRNA–mi­RNA–mRNA regulatory network.

Pathology informatics selected abstracts

January 2021—A major barrier to adopting whole slide imaging for primary diagnosis in the United States was FDA regulatory approval. However, the FDA approved marketing of the first whole slide imaging (WSI) system for digital pathology in 2017. The agency subsequently cleared Leica’s Aperio AT2 DX system for in vitro diagnostic use to aid pathologists in reviewing and interpreting digital images of surgical pathology slides prepared from formalin-fixed paraffin-embedded tissue. The authors conducted a study in which they compared pathologists’ primary diagnoses rendered through the use of WSI versus standard glass microscopy. Their multicenter, double-blind, randomized clinical trial was conducted at five sites: the University of California Davis, Pacific Rim Pathology, Dignity Health, TriCore Reference Laboratories, and Intermountain Healthcare.
