Updates in the Management of Paraneoplastic Syndrome.

Paraneoplastic neurological syndromes (PNS) are defined as remote neurologic immune-mediated effects triggered by underlying systemic tumors. While recognizing specific syndromes can aid early cancer detection, overutilization of paraneoplastic assays in the absence of a classic syndrome can precipitate overdiagnosis and overtreatment. PNS involve autoantibodies targeting intracellular or extracellular antigens, with variable immunotherapy responses based on antigen type.

Cardiac sarcoidosis: a comprehensive review of risk factors, pathogenesis, diagnosis, clinical manifestations, and treatment strategies.

Cardiac Sarcoidosis (CS) is a deadly consequence of systemic sarcoidosis that inflames all three layers of the heart, especially the myocardium-clinical signs of CS range from asymptomatic disease to abrupt cardiac death. CS generally remains undiagnosed secondary to a lack of definitive diagnostic criteria, a high percentage of false negative results on endomyocardial biopsy, and ill-defining clinical manifestations of the disease. Consequently, there is a lack of evidence-based recommendations for CS, and the present diagnostic and therapeutic management depend on expert opinion.

A Brain, A Heart, and the Courage: Balancing Benefit and Toxicity of Immunotherapy in Melanoma.

The overall survival of advanced melanoma has improved dramatically. Immunotherapies, specifically checkpoint inhibitors, have played a large role in this improvement. These agents have also shown benefit in the adjuvant setting, are approved for treatment of resected stage II, III, and IV melanoma, and play an evolving role in the neoadjuvant setting.

Rituximab for Immune Checkpoint Inhibitor Myasthenia Gravis.

The use of immune checkpoint inhibitors (iCPI) in the treatment of multiple cancers has gained prominence due to their high efficacy. However, neurological immune-related adverse events (irAEs) such as myasthenia gravis (MG) have been associated with iCPI therapy. Most of these neurological irAEs are rare, and in many cases, their diagnoses and management can be challenging.

Immunotherapy Induced Myasthenic-Like Syndrome in a Metastatic Melanoma Patient With Amyotrophic Lateral Sclerosis.

Immunotherapy agents such as ipilimumab and nivolumab are immensely effective in the treatment of various malignancies. Despite this, neurologic immune-related sequelae (NIRS) have been observed. Prompt diagnosis and treatment is critical to improve patient outcomes.

Immune checkpoint inhibitor induced anti-glutamic acid decarboxylase 65 (Anti-GAD 65) limbic encephalitis responsive to intravenous immunoglobulin and plasma exchange.

Immune checkpoint inhibitors have made significant advances in available cancer treatment options towards progression-free and overall survival in cancer patients by potentiating own anti-tumor immune response. Anti-programmed death (PD-1) and anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) have been increasingly associated with neurologic complications. LE is a rare complication and like many complications secondary to immunotherapy, there is no standard for evaluation and treatment.
