EGPA — diagnosed 9 months earlier due to fever, acute dyspnea, acute kidney injury, and peripheral neuropathy with hypereosinophilia, high serum eosinophilic cationic protein levels, perinuclear-ANCA pattern on indirect immunofluorescence assay, high anti-MPO antibody levels, and increased IgE levels — was in remission and under almost complete symptoms control with only mild paresthesia of the right foot digits. Here, MPO is linked to peripheral neuropathy.
