BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease that causes severe demyelination, especially in the optic nerve and spinal cord with typical clinical manifestations of acute optic neuritis and transverse myelitis. The symptoms can occur simultaneously or separated by a variable period. NMOSD is associated with serum aquaporin antibodies 4 immunoglobulin G (AQP4-IgG). CASE PRESENTATION: We report a case of a 22-year-old male with complaints of weakness of all four limbs, impaired vision, urinary incontinence, and dyspnea. The Expanded Disability Status Scale (EDSS) was nine. Spinal magnetic resonance imaging (MRI) showed longitudinal extensive transversal myelitis. The brain MRI showed a normal impression, whereas the brain magnetic resonance spectroscopy (MRS) examination showed a description of the mild demyelination process. The serum antibody AQP4 (AQP4-IgG) results were seronegative, the cerebrospinal fluid examination was normal, and the oligoclonal band was negative. The ophthalmoscopic examination found bilateral papillary atrophy but optical coherence tomography (OCT) was still normal. Somatosensory evoked potential and visual evoked potential examinations were abnormal. The patient was diagnosed with NMOSD and was given combination immunosuppressant therapy, corticosteroids, and therapeutic plasma exchange. The patient experienced significant improvement with EDSS decreased to six. CONCLUSION: In the case of relapsing NMOSD patient, combination therapy of immunosuppressants, corticosteroids, and TPE was used. There were significant improvements from EDSS nine to six.

AbstractTherapeutic plasma exchange (TPE) is a treatment administered with the aim of removing a pathogenic material or compound causing morbidity in a variety of neurologic, hematologic, renal, and autoimmune diseases. In this study, we aimed to assess the indications, efficacy, reliability, complications, and treatment response of pediatric patients for TPE. This retrospective study analyzed data from 39 patients aged from 0 to 18 years who underwent a total of 172 TPE sessions from January 2015 to April 2018 in a tertiary pediatric intensive care unit. Indications for TPE were, in order of frequency, macrophage activation syndrome (28.2%, n = 11), renal transplantation rejection (15.4%, n = 6), liver failure (15.4%, n = 6), Guillain–Barre's syndrome (15%, n = 6), hemolytic uremic syndrome (7.7%, n = 3), acute demyelinating disease (7.7%, n = 3), septic shock (5.1%, n = 2), and intoxication (5.1%, n = 2). No patient had any adverse event related to the TPE during the procedure. The TPE session was ended prematurely in one patient due to insufficient vascular access and lack of blood flow (2.6%). In the long term, thrombosis due to the indwelling central catheter occurred (5.1%, n = 2). TPE appears to be an effective first-stage or supplementary treatment in a variety of diseases, may be safely used in pediatric patients, and there are significant findings that its area of use will increase. In experienced hands and when assessed carefully, it appears that the rate of adverse reactions and vascular access problems may be low enough to be negligible.
