A short-term functional recovery comparison of therapeutic plasma exchange and immunoadsorption in severe acute neuroimmune diseases. Int Immunopharmacol 2024; 140:112796. [PMID: 39096871 DOI: 10.1016/j.intimp.2024.112796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 06/24/2024] [Accepted: 07/23/2024] [Indexed: 08/05/2024]
Abstract
OBJECTIVE To compare the differential impact of recombinant protein A immunoadsorption (PAIA) or therapeutic plasma exchange (TPE) on neurological functional improvement and quality of life in patients afflicted with severe acute neuroimmune diseases, including Guillain-Barré syndrome (GBS), myasthenia gravis (MG), neuromyelitis optica spectrum disorder (NMOSD), and anti-NMDA receptor encephalitis (NMDARE). METHODS The retrospective study included 29 patients with moderate to severe disability (modified Rankin scale, mRS≥3) due to acute neuroimmune diseases at the second Xiangya hospital from January 2021 to January 2023. The clinical efficacy of PAIA and TPE in improving neurological function (ΔmRS≥1) and the difference in favorable functional outcomes (mRS 0-2) at three months were evaluated. The impact of both treatments on patients' health-related quality of life (HRQoL) was assessed using a visual analog scale (EQ-VAS) score ranging from 0 to 100. RESULTS The findings revealed that the PAIA group exhibited a significantly higher rate of improvement in modified Rankin scale (mRS) scores (ΔmRS≥1) at the three-month follow-up compared to the TPE group (94.4 % vs. 54.5 %, p = 0.018). However, no statistically significant difference was observed between the two treatment modalities in terms of favorable neurological functional outcomes at the three-month mark. Furthermore, the PAIA group demonstrated a significantly higher EQ-VAS score at 14 days post-treatment compared to the TPE group (60.0 vs. 47.7, p = 0.017). CONCLUSION In the short-term management of severe acute neuroimmune diseases, PAIA may present a greater probability of improving neurological function and facilitating an earlier enhancement of quality of life compared to TPE.

Abstract
Anti-NMDA receptor encephalitis (NMDARE), an autoimmune encephalitis associated with autoantibodies against the N-methyl-D-aspartate (NMDA) receptor, affects predominantly young women and is associated with psychiatric symptoms, seizures, movement disorders, and autonomic instability. Traditional treatments of anti-NMDA receptor encephalitis involve corticosteroids, intravenous immunoglobulin, plasmapheresis, cyclophosphamide, and rituximab. However, many controversies remain in the treatment for NMDA receptor encephalitis, such as optimal timing and combination of different immunotherapies, the role of newer strategies (e.g., bortezomib or tocilizumab) for severe and refractory patients, and the need or not for long-term immunosuppression. Our goal was to perform a scoping review to discuss the controversial topics of immunotherapy for NMDA receptor encephalitis and propose operational definitions to guide clinical practice and future research in the field.

Lei Y, Cui TJ, Wang XH, Zhang XM, Tang C, Zheng ZH. Plasma adsorption in refractory chronic gouty arthritis flare: A case report. Front Immunol 2022; 13:1045982.

Abstract
Background Along with uric acid, which is the primary driving factor of gout, downstream inflammatory mediators have been shown to be involved in the pathogenesis of gouty arthritis flares. Extracorporeal haemadsorption is an emerging technology for the treatment of dysregulated inflammatory states by effectively removing cytokines from the bloodstream. Whether haemadsorption was effective in refractory gout flares has not been reported in the literature. Case summary We report the case of a 52-year-old male who presented with refractory gouty arthropathy for 30 years. His uric acid levels were poorly controlled due to poor diet and treatment compliance. Tophi were found to have precipitated in multiple joints and subcutaneous tissue. In the last 2 years, his incidents of gouty flares had become more frequent, and resistant to the medications, including colchicine, allopurinol, febuxostat, glucocorticoids, and NSAID analgesics. He had experienced a triad of chills, high fever and arthritis for the past 2 weeks. Therefore, he took 2 mg colchicine twice daily for 2 weeks with no improvement in his pain. Proinflammatory cytokines, such as interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α), were found to be remarkably elevated. Given that conventional treatment was unsuccessful, we tried to employ plasma adsorption (PA) to remove inflammatory cytokines. After 4 sessions, symptoms, such as fever, joint swelling and pain, were greatly improved. Meanwhile, the levels of proinflammatory factors such as IL-6 and TNF-α were found to be decreased, while the anti-inflammatory factor IL-10 remained the same during the course. He was followed up for 8 months and arthritis have flared up twice in response to a high-purine diet. Conclusion Our study suggests that plasma adsorption (PA) may be a promising and feasible treatment for refractory gout when conventional treatments are unsatisfactory or contraindicated. However, more clinical trials are needed to verify the efficacy and safety of the treatment. Core tip Chronic gouty arthritis flares are refractory to conventional treatment, such as uric acid-lowering drugs and NSAID analgesics. Due to the involvement of inflammatory cytokines, plasma adsorption was employed to alleviate flares by removing inflammatory mediators. Herein, we report a 52-year-old male who presented with refractory gouty arthropathy for 30 years, manifested with a triad of chills, high fever and arthritis. He underwent several sessions of plasma adsorption, and his symptoms soon improved, along with a drop in inflammatory mediators. We conclude that plasma adsorption may be a promising and feasible treatment for refractory gout when conventional treatments are unsatisfactory or contraindicated.

Treatment of Severe Japanese Encephalitis Complicated With Hashimoto's Thyroiditis and Guillain-Barré Syndrome With Protein A Immunoadsorption: A Case Report. Front Immunol 2022; 12:807937.

Abstract
A severely comatose female patient was diagnosed with Japanese encephalitis (JE). Her condition was complicated by Hashimoto’s thyroiditis (HT) and Guillain-Barré syndrome (GBS). After antiviral, glucocorticoid, and immunoglobulin treatment, the patient’s consciousness was restored, and she could breathe spontaneously. Following this, new-onset, primarily demyelinating GBS developed, which progressed to demyelination combined with axonal injury. The patient was switched to protein A immunoadsorption (PAIA) therapy, and her Hughes score decreased rapidly, from 4 to 1 after 6 months. This patient is the first to receive PAIA combined with an antiviral-glucocorticoid-immunoglobulin regimen to treat encephalitis, meningitis, HT, and GBS caused by JE infection, thereby reflecting the importance of clinical application of PAIA in the treatment of immunological complications of JE.
