Seronegative Autoimmune Hepatitis: A Rare Manifestation of COVID-19.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus pandemic in 2019, commonly causes hepatic dysfunction. Liver injury ranges from mildly elevated liver enzymes to fulminant liver failure. Interestingly, there are cases that suggest a relationship between autoimmune hepatitis (AIH) in patients who either contracted coronavirus disease in 2019 (COVID-19) or were vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We present a case of a 39-year-old female without a significant past medical history who presented with two weeks of jaundice, abdominal pain, nausea, and diarrhea. She had significantly elevated liver enzymes and conjugated hyperbilirubinemia. She also tested positive for SARS-CoV-2 but denied any respiratory symptoms; her vaccination status was up to date. She denied taking hepatotoxic agents, and the workup was negative for acute viral hepatitis. The F-actin antibody level was 22 units, but serum immunoglobulin (IgG), anti-nuclear (ANA), anti-smooth muscle, anti-mitochondrial, anti-liver/kidney microsomal-1, anti-soluble liver antigen, and anti-neutrophil cytoplasmic antibodies levels were not elevated. Computerized tomography of the abdomen and pelvis revealed hepatic hemangiomas. Eventually, a liver biopsy was performed, and histology showed active lymphoplasmacytic hepatitis with prominent regenerative changes and areas of confluent necrosis. The histologic findings, along with the patient's clinical course, were suggestive of autoimmune hepatitis. The patient was started on systemic steroids with an improvement of abdominal pain and jaundice, as well as an improvement of her liver chemical profile. She was discharged with plans for hepatology clinic follow-up. Here, we present a rare case of seronegative AIH in a patient with a recent COVID-19 infection and discuss the potential underlying mechanism. We call for further investigation into the relationship between autoimmune dysfunction and COVID-19, as well as the pathophysiology behind it. Analyzing how the virus causes autoimmune dysfunction may allow clinicians to more effectively treat patients suffering from sequelae of COVID-19 infection, and it is important not to exclude autoimmune hepatitis from the differential based on the initial autoimmune workup.
