Acute Onset Chronic Inflammatory Demyelinating Polyneuropathy Following COVID-19

This is the authors' abstract. We don't add key points for this paper.

The cases of Guillain Barre Syndrome (GBS) have been reported following the coronavirus disease 2019 (COVID-19). Here, we describe a case that evolved from GBS to chronic inflammatory demyelinating polyneuropathy (CIDP) after COVID-19 in terms of contributing to the literature due to its different aspects. In the cerebrospinal fluid examination of the acute onset mixed type polyneuropathy case, albuminocytological dissociation was not detected. The patient was given a loading dose and monthly maintenance intravenous immunoglobulin (IVIG) for six months. Blood ferritin levels gradually decreased in parallel with clinical improvement. Four months after the IVIG treatment was terminated, the findings recurred and the CIDP was developed and IVIG treatment was continued. Long-term follow-up of post-COVID-19 GBS patients is important in terms of recurrence and chronicity. Ferritin level may be a biochemical marker in the clinical follow-up of these cases.
