    Study Notes

    European Guidelines for the Management of Narcolepsy in Adults and Children

    • Narcolepsy is a rare hypothalamic disorder that affects 25-50 persons out of 100,000.

    • It can significantly affect quality of life, with symptoms including excessive daytime sleepiness, fragmented and disturbed nighttime sleep, cataplexy, and hallucinatory experiences around sleep-wake transitions.

    • Narcolepsy is usually a sporadic acquired immune-mediated condition that develops in people who are genetically predisposed.

    • The European Academy of Neurology, European Sleep Research Society, and European Narcolepsy Network created a task force of 18 narcolepsy specialists and 4 patient representatives to provide evidence-based guidelines for the management of narcolepsy in adults and children.

    • A total of 10,247 references were evaluated, 308 studies were assessed and 155 finally included in developing the guidelines.

    • The main recommendations include scheduled naps, modafinil, pitolisant, sodium oxybate, and solriamfetol for excessive daytime sleepiness in adults, and scheduled naps, sodium oxybate, modafinil, methylphenidate, pitolisant, and amphetamine derivatives for excessive daytime sleepiness in children.

    • For cataplexy in adults, sodium oxybate, venlafaxine, clomipramine, and pitolisant are recommended, and for cataplexy in children, sodium oxybate and antidepressants are recommended.

    • Treatment choices should be tailored to each patient's symptoms, comorbidities, tolerance, and risk of potential drug interactions.

    • The guidelines also evaluate pharmacological treatments that are potentially disease-modifying as well as therapies for a variety of comorbid conditions such as obesity, sleep-disordered breathing, rapid eye movement sleep behavior disorder, restless legs syndrome, and periodic limb movements.

    • Non-pharmacological treatments such as cognitive-behavioral therapy, sleep hygiene, and regular exercise can also improve symptoms of narcolepsy.

    • The guidelines also include expert statements and patient perspectives on the management of narcolepsy.

    • The aim of the guidelines is to provide up-to-date, evidence-based recommendations for the management of narcolepsy in both adults and children.Clinical Guidelines for the Management of Narcolepsy

    • The guidelines were developed by a task force established by three societies in 2017 and finalized in September 2020.

    • The task force used the GRADE approach and identified key questions and outcomes essential for clinical management.

    • The literature search was conducted between July and October 2018 and updated in July and October 2020.

    • Non-pharmacological management should always be considered first, and individual factors should be taken into account.

    • There is limited scientific evidence for the efficacy of non-pharmacological treatments other than scheduled napping.

    • Disease-modifying treatments for narcolepsy are not currently recommended.

    • Wake-promoting agents and sodium oxybate are effective in improving excessive daytime sleepiness (EDS).

    • Different compositions or formulations of sodium oxybate may have an additional impact on improving disturbed nocturnal sleep (DNS).

    • Stimulants may increase heart rate and blood pressure and require careful monitoring.

    • Sleep paralysis and hypnagogic/hypnopompic hallucinations are reported by approximately 50% of patients with narcolepsy, but there is no evidence for the efficacy of treatments.

    • There is a need for specific trials on the impact of compounds, including antidepressants and sodium oxybate, on sleep paralysis and hypnagogic/hypnopompic hallucinations.

    • Improving daily performance, quality of life measures, and the ability to work are key aims of narcolepsy management.Pharmacological Treatment and Management of Narcolepsy: Recommendations and Future Directions

    • Psychiatric disturbances, including depression and anxiety, are common in narcolepsy patients.

    • Treatment for psychiatric disorders in narcolepsy should follow general principles for the general population.

    • Shared compounds for symptoms of narcolepsy and comorbid mood disorders should be considered where appropriate.

    • There is no established recommendation for the use of narcoleptic drugs during puberty.

    • Treatment strategies for narcolepsy in children and adolescents should take into account developmental aspects.

    • Non-pharmacological approaches, such as cognitive behavioral therapy, should be considered for psychiatric comorbidities in narcolepsy.

    • The lack of specific studies makes it difficult to support any particular treatments for depression in narcolepsy.

    • Almost no head-to-head trials have been performed between drugs for the treatment of narcolepsy.

    • Sodium oxybate is the only EU-approved medication for the treatment of narcolepsy.

    • Trials on the safety and efficacy of pitolisant in children are yet to be published.

    • The clinical efficacy of sodium oxybate for the treatment of EDS and cataplexy in children was first reported in 2018.

    • The clinical evidence for efficacy of pharmacological treatment of any symptom of narcolepsy in children is limited.Guidelines for the Management of Narcolepsy: Key Recommendations and Patient Perspectives

    • Narcolepsy is a sleep disorder that affects multiple aspects of daily life, including excessive daytime sleepiness (EDS), cataplexy, and disturbed nocturnal sleep (DNS).

    • Pharmacological treatment is the primary approach to managing narcolepsy, with various drugs available, including modafinil, methylphenidate, sodium oxybate, amphetamine derivatives, and pitolisant.

    • Treatment may be complicated by factors such as age, pregnancy, breastfeeding, and comorbidities, and discontinuation of drug therapy before pregnancy is strongly advised.

    • Low doses of antidepressants seem relatively safe for narcolepsy treatment, but recent studies have raised doubts about the safety of modafinil and its potential to cause congenital defects.

    • L-carnitine may have a positive effect on reducing daytime nap time in some patients.

    • Perioperative risk in narcolepsy is generally not an independent risk factor for surgery, but existing comorbidities and medication use may affect risk.

    • Patients' views and needs should be considered in developing clinical practice and patient-oriented guidelines, including addressing non-pharmacological treatments and specialized ancillary health workers.

    • Non-pharmacological treatments such as regular naps, exercise, good sleeping habits, and regular schedules may help manage symptoms of narcolepsy.

    • Complete symptom control in narcolepsy is relatively rare, and less than 50% of treated patients are normalized on subjective measures of EDS.

    • There is an unmet need for specialized ancillary health workers, including nurses and psychologists, working in sleep centers specializing in narcolepsy.

    • Clinical observational studies with long-term follow-up and precise individual treatment plans are necessary to improve the development of disease-modifying drugs and evaluate symptomatic medications.

    • The guidelines will be updated in 5 years or earlier if major changes in evidence or new interventions become available.

    Evidence-based guidelines for the management of narcolepsy in adults and children

    • Narcolepsy is a disabling hypothalamic disorder that presents with a variety of sleep-wake and other symptoms.
    • Narcolepsy with typical cataplexy (type 1 narcolepsy, NT1) is considered a distinct entity, associated with hypocretin deficiency, while narcolepsy without cataplexy (type 2 narcolepsy, NT2) is less clearly defined.
    • The precise etiology of narcolepsy is unknown, but it is usually a sporadic acquired immune-mediated condition that develops in people who are genetically predisposed.
    • Worldwide prevalence estimates suggest that approximately 25–50 persons out of 100,000 are affected.
    • Narcolepsy potentially affects every aspect of daily life with considerable personal, social and economic consequences.
    • Current treatments include non-pharmacological and pharmacological approaches.
    • Treatment guidelines for narcolepsy were first published in Europe in 2006 and in the USA in 2007.
    • Criteria for diagnosing narcolepsy into types 1 and 2 (NT1 and NT2) were revised in 2014 by the American Academy of Sleep Medicine.
    • There have been considerable developments in our understanding of both the etiopathology and clinical characteristics in narcolepsy since 2006.
    • The European Academy of Neurology (EAN), European Sleep Research Society (ESRS), and European Narcolepsy Network (EU-NN) nominated a task force of 18 narcolepsy specialists to provide evidence-based guidelines for the management of narcolepsy in both adults and children.
    • According to the EAN recommendations, 10 relevant clinical questions were formulated in PICO format.
    • The main recommendations include scheduled naps, modafinil, pitolisant, sodium oxybate (SXB), solriamfetol, methylphenidate, amphetamine derivatives, venlafaxine, and clomipramine, and treatment choices should be tailored to each patient's symptoms, comorbidities, tolerance, and risk of potential drug interactions.

    Clinical Evidence and Recommendations for the Management of Narcolepsy

    • Disease-modifying treatments for the remission or improvement of narcolepsy are not recommended.
    • Monoclonal antibody therapies and selective hypocretin receptor agonists are promising new treatments for preventing or slowing hypocretin neuron loss.
    • Non-pharmacological management approaches, such as planned daytime naps and a healthy lifestyle, should be considered first for symptom control.
    • Informed scientific knowledge of narcolepsy and attempts to implement a fixed schedule for sleep and daytime activities with short scheduled naps are important.
    • Joining a patients' organization can be helpful for information, exchange, and support.
    • Symptomatic pharmacological treatments should focus on improving the sleep-wake cycle of narcoleptic patients with attention to daytime performance and reducing cataplexy.
    • Treatment goals and choices should consider an individual's symptoms, preferences, and comorbidities.
    • Wake-promoting agents and sodium oxybate have clear evidence for improving excessive daytime sleepiness (EDS).
    • Long-term efficacy and safety data for EDS treatments are limited, but a recent study supports the safety and efficacy of pitolisant for up to 1 year.
    • Stimulants may increase heart rate and blood pressure and require careful monitoring.
    • Head-to-head studies for comparing efficacy between different stimulants/wake-promoting drugs are lacking.
    • New compounds, such as novel histamine 3 receptor inverse agonists and hypocretin receptor agonists, may become available for treating EDS in the future.

    Update on Treatment and Diagnosis of Chemotherapy-Induced Peripheral Neuropathy

    • Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent adverse effect of anticancer agents, which primarily affects sensory nerves and causes pain, tingling, and numbness in a symmetrical “glove and stocking” distribution.

    • The pathophysiology of CIPN is complex and varies with the different classes of chemotherapy drugs. It involves multiple mechanisms, including mitochondrial toxicity and oxidative stress, DNA damage, axonal transport disruption, and ion channel remodeling in peripheral nerves.

    • Patients with a more severe CIPN presentation experience a decreased quality of life physically, emotionally, and socially, and it has been associated with interfering with patients’ ability to work and a greater financial burden.

    • There are currently no approved or effective agents for CIPN prevention, and duloxetine is the only medication that is an effective treatment against CIPN, but it has limited benefits.

    • Other options such as tricyclic antidepressants or anti-seizure medications have been explored, but trials show mixed results, and there are no recommendations on these other therapies.

    • The epidemiology of CIPN is complicated because of the many different scales used to assess CIPN, and there is no standardized approach for assessing and diagnosing CIPN.

    • Assessment techniques can be divided into objective and subjective approaches, with nerve conduction studies (NCS) and quantitative sensory testing (QST) being effective objective and subjective assessments, respectively.

    • Composite studies have become progressively favorable for assessing CIPN, with the most common one being the Total Neuropathy Score (TNS), which allows simultaneous assessment of graded physician-reported severity with objective sensibility measures and NCS.

    • The first step in diagnosing CIPN is to exclude other potential neuropathy causes such as preexisting conditions, association with surgery, and any other factors that would come with.

    • Prevention and treatment of CIPN are tremendously challenging because of the varying underlying pathophysiological causes with differing chemotherapy agents.

    • There is still a need to explore and develop efficacious treatments for CIPN, and future perspectives include ion channel-targeted therapies and drugs that inhibit anticancer agent-induced Schwann cell damage as potential therapeutic agents for CIPN.

    • The purpose of this review is to examine CIPN, innovative pharmacological and nonpharmacological therapy and preventive strategies for this illness, and future perspectives for this condition and its therapies.Treatment Options for Chemotherapy-Induced Peripheral Neuropathy (CIPN)

    • Clinical examination is usually used to diagnose CIPN following exclusion of other potential causes, but it cannot prove the origin of abnormalities in the nervous system.

    • Gabapentin and pregabalin both bind to the alpha2-delta protein and are first-line treatment options for neuropathic pain, but studies have shown that patients who respond poorly to gabapentin may experience a clinically significant improvement in pain when switching to pregabalin.

    • Erythropoietin (EPO) possesses neuroprotective effects and is a seemingly ideal candidate for CIPN; however, its utilization for the treatment of CIPN is highly contraindicated and should be approached with caution as EPO is associated with tumor cell growth.

    • Non-steroidal anti-inflammatory drugs (NSAIDs) can reduce pain symptoms and the underlying inflammation associated with pain, but studies involving NSAIDs in the treatment of CIPN are limited and require further evaluation.

    • Lidocaine is a sodium channel blocker that effectively relieves various causes of neuropathic pain, including CIPN. Intravenous (IV) lidocaine produced a significant, moderate long-term analgesic effect in patients with CIPN.

    • Magnesium infusion has been postulated as a potential therapeutic option for CIPN, but other studies have failed to demonstrate any efficacy in using magnesium infusions to treat CIPN. Similarly, calcium infusions failed to reduce CIPN in multiple studies.

    • Selective serotonin and norepinephrine reuptake inhibitors (SNRIs) are the first and only FDA-approved drug class for treating pain caused by diabetic peripheral neuropathy. Duloxetine is often considered a first-line treatment option for CIPN.

    • Tricyclic antidepressants (TCAs) have long been recognized for their use in treating neuropathic pain, but studies have found these drugs to be ineffective in treating pain associated with CIPN.

    • Topical mixtures of amitriptyline and ketamine, and amitriptyline, ketamine, and baclofen have not shown significant improvement in CIPN symptoms compared to placebo.

    • Capsaicin, a transient receptor potential vanilloid receptor (TRPV1) agonist, has demonstrated efficacy in treating neuropathic pain, including that associated with CIPN.

    • Mangafodipir, a manganese chelate and superoxide dismutase mimetic, has provided evidence for the use in treating CIPN, where individuals experienced a significant reduction in pain.

    • Non-pharmacologic interventions, such as acupuncture, massage, foot bath, and physical therapy, have produced a significant reduction in CIPN symptoms. Scrambler therapy, a noninvasive treatment strategy for CIPN, has shown promising results but requires further studies. Neurofeedback therapy is a non-invasive treatment thatAdvances in Treatment Options for Chemotherapy-Induced Peripheral Neuropathy

    • Chemotherapy-induced peripheral neuropathy (CIPN) is a common adverse effect of chemotherapy that causes pain and affects patients' quality of life.

    • CIPN is difficult to treat, and there is no standardization on which assessment and diagnosis methods to use.

    • The pathophysiology of CIPN is not well understood, leading to many different pharmacological and non-pharmacological agents being used in trials to find prevention and treatment methods.

    • Duloxetine is currently the only recommended agent for CIPN treatment, but many other agents show promise and need further studies, such as IV lidocaine, cannabinoids, oral glutamine, cryotherapy, acupuncture, massage therapy, and exercise.

    • Some therapies can increase the risk and severity of CIPN and should be avoided, including EPO and acetyl-L-carnitine (ALC).

    • Non-pharmacological therapies have proven to be helpful in some patients, including integrative and behavioral approaches, acupuncture, massage therapy, and mind-body techniques.

    • Glutamine is an amino acid that plays an important role in our immune system and intestinal health, but studies have not supported the efficacy of oral glutamine therapy in alleviating CIPN symptoms.

    • Topical treatments have been explored, such as menthol and potential combinations, but further studies are needed.

    • Scrambler therapy is a treatment that sends "non-pain" signals to replace "pain" signals perceived by the nerves, reducing the pain felt by the patient.

    • Pharmacological agents being explored include MR309, a selective antagonist of the sigma 1 receptor, which has shown promise in reducing chronic neuropathic pain.

    • The goal of future directions in the treatment of CIPN is to better understand the pathophysiology and find a therapy that can help treat this condition.

    • Funding for research on CIPN is available, and studies are ongoing to find effective treatment options for patients.Current approaches for the prevention and treatment of chemotherapy-induced peripheral neuropathy

    • Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating side effect of cancer treatment.

    • CIPN is characterized by a range of symptoms, including pain, numbness, tingling, and weakness, which can affect quality of life and limit treatment options.

    • There is no single effective treatment for CIPN, and current approaches are focused on prevention and symptom management.

    • Prevention strategies include reducing chemotherapy dose, using neuroprotective agents, and incorporating alternative therapies such as acupuncture and exercise.

    • The use of neuroprotective agents such as calcium and magnesium infusions, erythropoietin, and anticonvulsants such as gabapentin and pregabalin have shown promise in managing CIPN symptoms.

    • Antidepressants such as duloxetine and venlafaxine have also been used to manage CIPN-related pain.

    • The Total Neuropathy Score (TNS) is a commonly used tool for assessing the severity of CIPN symptoms.

    • The National Cancer Institute-Common Toxicity Scale (NCI-CTC) is another tool used to assess the severity of CIPN symptoms, but it has limitations.

    • Lidocaine, a local anesthetic, has been used to manage CIPN-related pain, but its effectiveness is still being studied.

    • Magnesium and calcium infusions have been found to be effective in preventing oxaliplatin-induced sensory neurotoxicity.

    • Gabapentin and pregabalin are anticonvulsants that have shown efficacy in managing neuropathic pain, including CIPN-related pain.

    • More research is needed to identify effective treatments for CIPN and to better understand the underlying mechanisms of CIPN.

    Update on Treatment and Diagnosis of Chemotherapy-Induced Peripheral Neuropathy

    • Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent adverse effect of anticancer agents, which primarily affects sensory nerves and causes pain, tingling, and numbness in a symmetrical “glove and stocking” distribution.

    • The pathophysiology of CIPN is complex and varies with the different classes of chemotherapy drugs. It involves multiple mechanisms, including mitochondrial toxicity and oxidative stress, DNA damage, axonal transport disruption, and ion channel remodeling in peripheral nerves.

    • Patients with a more severe CIPN presentation experience a decreased quality of life physically, emotionally, and socially, and it has been associated with interfering with patients’ ability to work and a greater financial burden.

    • There are currently no approved or effective agents for CIPN prevention, and duloxetine is the only medication that is an effective treatment against CIPN, but it has limited benefits.

    • Other options such as tricyclic antidepressants or anti-seizure medications have been explored, but trials show mixed results, and there are no recommendations on these other therapies.

    • The epidemiology of CIPN is complicated because of the many different scales used to assess CIPN, and there is no standardized approach for assessing and diagnosing CIPN.

    • Assessment techniques can be divided into objective and subjective approaches, with nerve conduction studies (NCS) and quantitative sensory testing (QST) being effective objective and subjective assessments, respectively.

    • Composite studies have become progressively favorable for assessing CIPN, with the most common one being the Total Neuropathy Score (TNS), which allows simultaneous assessment of graded physician-reported severity with objective sensibility measures and NCS.

    • The first step in diagnosing CIPN is to exclude other potential neuropathy causes such as preexisting conditions, association with surgery, and any other factors that would come with.

    • Prevention and treatment of CIPN are tremendously challenging because of the varying underlying pathophysiological causes with differing chemotherapy agents.

    • There is still a need to explore and develop efficacious treatments for CIPN, and future perspectives include ion channel-targeted therapies and drugs that inhibit anticancer agent-induced Schwann cell damage as potential therapeutic agents for CIPN.
