H7N9 Influenza A-induced Pneumonia Associated with Acute Myelitis in an Adult
Open accessAbstract
Recently, we encountered three patients infected with an avian influenza A virus (H7N9) who exhibited upper respiratory catarrh symptoms, pharyngalgia, a high fever and hypodynamia in the early stages of the disease. Their conditions deteriorated rapidly, and one-sided pneumonia progressed to two-sided pneumonia. The patients developed respiratory failure and even acute respiratory distress syndrome (ARDS). One patient experienced numbness of the lower limbs, urinary retention and fecal incontinence. Magnetic resonance imaging (MRI) of the spinal cord indicated edema at the thoracic level, and the patient was diagnosed with acute myelitis. This report details the diagnosis and treatment of a patient with H7N9-induced pneumonia associated with acute myelitis.

Human influenza viruses often cause pneumonia and acute respiratory distress syndrome, but on rare occasions they can cause extra-respiratory illnesses including meningitis, encephalitis, meningoencephalitis, and myelitis.
“Human influenza viruses often cause pneumonia and acute respiratory distress syndrome (ARDS) [87], but on rare occasions, they can cause extra-respiratory illnesses, including meningitis [87], encephalitis [88], meningoencephalitis, and myelitis [89].”
From Viral meningitis: an overview (2021) · cites this paper as [89]
Citation [89] follows “meningoencephalitis, and myelitis.” The Introduction says influenza-associated nervous-system symptoms are uncommon and lists myelitis among reported complications; the Abstract describes a patient with H7N9-associated acute myelitis. Our copy does not mention meningoencephalitis, so that part of the attributed claim is unsupported. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
