Neurological autoimmunity in melanoma patients: a comparison between those exposed and non-exposed to immune checkpoint inhibitors. J Neurol 2024; 271:3279-3290. [PMID: 38467790 DOI: 10.1007/s00415-024-12252-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 02/09/2024] [Accepted: 02/10/2024] [Indexed: 03/13/2024]
Abstract
BACKGROUND The clinical spectrum of melanoma-associated neurological autoimmunity, whether melanoma-associated paraneoplastic neurological syndromes (PNS) or induced by immune checkpoint inhibitors (ICI), is not well characterized. We aim to describe the clinical spectrum of melanoma-associated neurological autoimmunity. METHODS A systematic review of the literature combined with patients from French databases of paraneoplastic neurological syndromes was conducted. All melanoma patients with a possible immune-mediated neurologic syndrome were included and classified according to whether they had previously been exposed to ICI (ICI-neurotoxicity) or not (ICI-naïve) at first neurological symptoms. RESULTS Seventy ICI-naïve (literature: n = 61) and 241 ICI-neurotoxicity patients (literature: n = 180) were identified. Neuromuscular manifestations predominated in both groups, but peripheral neuropathies were more frequent in ICI-neurotoxicity patients (39.4% vs 21.4%, p = 0.005) whereas myositis was more frequent in ICI-naïve patients (42.9% vs 18.7%, p < 0.001). ICI-naïve patients had also more frequent central nervous system (CNS) involvement (35.7% vs 23.7%, p = 0.045), classical paraneoplastic syndrome (25.7% vs 5.8%, p < 0.001), and more frequently positive for anti-neuron antibodies (24/32, 75.0% vs 38/90, 42.2%, p = 0.001). Although more ICI-neurotoxicity patients died during the acute phase (22/202, 10.9% vs 1/51, 2.0%, p = 0.047), mostly myositis patients (14/22, 63.6%), mortality during follow-up was higher in ICI-naïve patients (58.5% vs 29.8%, p < 0.001). There was no significant difference in the frequency of life independence (mRS ≤ 2) in the surviving patients in both groups (95.5% vs 91.0%, p = 0.437). CONCLUSIONS Melanoma-associated PNS appear remarkably rare. The clinical similarities observed in neurological autoimmunity between ICI-treated and ICI-naïve patients, characterized predominantly by demyelinating polyradiculoneuropathy and myositis, suggest a potential prior immunization against melanoma antigens contributing to ICI-related neurotoxicity.

Absent well-characterized onconeural antibodies in 283 patients with various polyneuropathies: A retrospective monocenter study. J Neurol Sci 2020; 413:116804. [PMID: 32240853 DOI: 10.1016/j.jns.2020.116804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2019] [Revised: 03/23/2020] [Accepted: 03/24/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND Paraneoplastic neurological syndromes (PNS) might present as polyneuropathies (PNP). Because PNS are rare and PNP are frequent, it may be difficult to decide in patients with PNP of unclear or presumably idiopathic etiology whether to test for onconeural antibodies, which are highly predictive for PNS. In this regard, this is the largest study investigating the prevalence of onconeural antibodies in patients with PNP, in order to clarify whether such testing should be standard. METHODS Of 1842 consecutive patients, 283 were suitable and had stored serum samples for screening for onconeural antibodies (anti-Hu, Yo, Ri, CV2/CRMP5, Ma2, and amphiphysin) by ELISA: 159 patients with PNP of - despite laborious work-up - unknown etiology without cancer, 67 with Guillain-Barré syndrome (GBS), 31 with chronic inflammatory demyelinating PNP (CIDP), and 26 with cancer and PNP. RESULTS None of the 283 screening samples revealed high concentrations for any of the tested antibodies. Thirteen sera (4.6%) showing positive reactivity in the screening ELISA (11 with PNP of unknown etiology without cancer, one with GBS, and one with CIDP) most likely represented increased background activity, as confirmatory assays (immunoblotting and immunohistochemistry) were negative. Furthermore, none of these 13 patients had diagnosed cancer and 10 with sufficient follow-up data did not develop cancer during follow-up. Interestingly, none of the patients with known cancer and PNP was screened positive for any antibody reactivity. CONCLUSIONS Our data suggest that routine screening for onconeural antibodies in etiologically unclear and in presumably idiopathic (GBS and CIDP) PNP is not mandatory.

Abstract
INTRODUCTION In the past decade, intravenous immunoglobulins (IVIG) have been widely used and their administration has grown throughout the world. The current indications of IVIG in neurological diseases are discussed on the basis of the passed and current trials. Unlike other immuomodulatory agents, IVIG are well tolerated and have very few side effects and a good viral safety. STATE OF ART There is clinical evidence, based on controlled trials, for the effectiveness of IVIG in Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy and multifocal neuropathy with conduction blocks. In myasthenia gravis, the IVIG are effective especially in myasthenic crisis, but their synergistic effect with other treatments, the steroid sparing effect, and their long-term effect are unknown. These issues need to be addressed in further controlled clinical trials. In dermatoploymyositis, IVIG are reserved for steroid resistant patients. There is actually no support or no significant clinical benefit for the routine use of IVIG in other neurological diseases. PERSPECTIVES Further controlled trials are warranted to assess the quality of life, the dose-finding effect and their long-term efficacy in order to improve clinical practices. CONCLUSION Routine use of IVIG should be reserved for diseases in which positive controlled trials are available. For the remaining dysimmune diseases, IVIG should be assess in comparison with the other available therapies, taking into consideration the age of the patients, the safety of the IVIG and, in our country, the economic aspect.

Abstract
PURPOSE OF REVIEW Peripheral nervous system (PNS) involvement is of great diagnostic value in systemic vasculitides, because it occurs frequently and often early during the course of these diseases, despite the supposed blood-nerve barrier that should prevent or at least minimize PNS damage. However, it carries no poor prognostic value in vasculitides. Recent advances have been made in understanding the pathogenetic mechanisms of PNS involvement. RECENT FINDINGS Vasculitic neuropathy may result from primary or secondary systemic vasculitides, or may be restricted to the PNS, in a form that is now also considered to be a systemic vasculitis. The blood-nerve barrier is not as efficient as the blood-brain barrier. Inflammatory cell infiltration into the vasa nervorum and epineurial arteries leads to ischemic axonal nerve injury and is facilitated by additional breaches in the blood-nerve barrier, induced by proinflammatory cytokines, oxidative stress-derived molecules, and matrix metalloproteinases. Although animal models of myeloperoxidase or, now, proteinase 3-antineutrophil cytoplasmic autoantibody-inducing vasculitis have been developed, they do not support a role for antineutrophil cytoplasmic autoantibodies in PNS involvement. Treatment should be chosen based on the other organ involvement and the patient's general condition. When PNS involvement is isolated, corticosteroids alone should be used as first-line treatment. SUMMARY Apart from the so-called nonsystemic nerve vasculitis, PNS involvement is rarely the sole clinical sign of systemic necrotizing vasculitis, and its association with other typical manifestations is often suggestive of the diagnosis of vasculitis. Herein are summarized recent advances that have clarified but not yet fully elucidated the pathogenesis of peripheral neuropathy in systemic vasculitides, together with the latest clinical findings and therapeutic strategies.
