Abstract

Background: The spectrum of neurological complications from SARS-CoV-2 infection is under constant investigation. According to numerous publications, occurrence of neurological complications can be about 36.4%. There are no reports to date of the occurrence of bilateral median nerve neuritis in the wrist after SARS-CoV-2 infection. Case: A previously healthy 24 years old female was observed in March 2021 due to dysesthesias in both hands, associated with nocturnal discomfort and decreased grip strength. The symptoms started a month earlier with acroparesthesias. SARS-CoV-2 virus infection was in January 2021 and evolved favorably, with progressive remission in about 10 days. Prior to the infection she didn’t have any of the hand symptoms; denied diabetes or metabolic diseases. Negative tests for SARS-CoV-2 infection since February. April 2021, the patient returned with persistent dysesthesias in her hands. Normal EMG, however with Sensitive Conduction Speed (SCS) of 50 m/sec on the right wrist; on the left SCS 55 m/sec. Sensitive latency 2.8 on the right and 2.6 on the left. Amplitude 17 on the right and 24 on the left. MRI detected an increase in signal in PDFS sequences in both median nerves, in the carpal tunnel, with no detected variations in cross-sectional areas or masses. The treatment was a 30 days 150 mg benfotiamine in two daily doses. Discussion: There is a wide variation in the clinical presentation of SARS-CoV-2 infection, ranging from asymptomatic patients to death. Most frequent symptoms are fever, dry cough, sore throat, dyspnea, myalgia, fatigue, chills, diarrhea, chest pain and vomiting, and the most common complications pneumonia and acute respiratory distress syndrome. Neurological manifestations of viral infection can occur in about 36.4% and in 45.5% in severe disease. They include Guillán- Barré and Miller Fischer syndrome; however, these conditions usually occur in more severe cases of the disease, but this patient hadn’t the typical picture of ataxia, ophthalmoplegia and areflexia. Benfotiamine is a synthetic derivative of thiamine with a multifaceted therapeutic profile, with a therapeutic role especially in diabetic neuropathy. Conclusion: Knowledge and recognition of neurological manifestations of SARS-CoV-2 infection and early detection of secondary peripheral neuropathies result in improvement of patients' clinical results and development of ideal ways of treatment. Although only a small percentage of patients develop peripheral neuropathy, in a pandemic this can result in a major social and health impact. The reported case is the first case of bilateral secondary median nerve neuritis in the literature. Level of evidence 4.
