Background Acute motor and sensory axonal neuropathy (AMSAN) is a subtype of Guillain-Barré syndrome (GBS) differentiated by nerve conduction studies (NCS) and characterized by symmetric ascending paralysis often involving respiratory muscles. While opsoclonus, which is involuntary chaotic rapid eye movements, is not a common manifestation of GBS. Moreover, little published data are available on the relation between liver enzymes elevation and GBS. Case presentation A 42-year-old man presented to Al Mouwassat University Hospital with weakness in all limbs and dyspnea. Examination showed an elevated respiratory rate, hyporeflexia, and decreased strength of upper and lower limbs. Analysis of cerebrospinal fluid revealed an albuminocyto-dissociation suggesting the diagnosis of GBS and subsequent plasmapheresis. NCS confirmed a diagnosis of AMSAN. Elevation in liver enzymes was noticed prompting further exploration with no positive findings. Despite treatment efforts, the patient developed severe dyspnea, deterioration in cognitive abilities, and opsoclonus with a normal brain MRI. Unfortunately, he developed respiratory failure which lead to his death. Conclusion In this case, we highlight the occurrence of opsoclonus which is a rarely-encountered manifestation of GBS, in addition to an unexplained elevated liver enzyme, the thing that could contribute to larger research to further comprehend the pathophysiology of GBS.
Background: Adult-onset Still’s disease (AOSD) is a rare auto-inflammatory disorder with unknown etiology by which an infectious trigger is usually responsible for the onset of the disease. It is diagnosed by exclusion when certain clinical, biochemical, and radiological criteria are met after excluding all other potential causes. Besides, SARS‑CoV‑2 infection is increasingly being reported to have autoimmune complications. In the literature, 3 AOSD cases have been reported to be triggered by SARS‑CoV‑2 infection and here we report the fourth. Case presentation: A 24-year-old female doctor suffered from fever, sore throat, and mild cough a few days after a shift in the COVID-19 ward. A week later, she developed polyarthritis, salmon-colored rash, and high-grade fever, and the laboratory findings were indicating an inflammatory syndrome. COVID-19 IgM antibodies were positive indicating recent infection. After running a battery of tests, infectious, neoplastic, and rheumatic causes of these symptoms that persisted for about 50 days were excluded which led to a diagnosis of AOSD after fulfilling its criteria with subsequent treatment with methylprednisolone. Drastic improvement was achieved with no recurrence until the date of reporting. Conclusion: This case presents a new consequence of COVID-19 and adds to the emerging cumulative experiences with this disease. We encourage health care professionals to report such cases to further understand the nature of this infection and its possible outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
