Current Treatment of Selected Pediatric Sleep Disorders NEUROTHERAPEUTICS Sullivan, S. S. 2012; 9 (4): 791-800


While pediatric sleep disorders are relatively common, treatments are often not straightforward. There is often a paucity of gold standard studies and data available to guide clinicians, treatments may yield arguably incomplete results, interventions may require chronic use, and/ or involve multiple modalities including behavioral interventions that require high parental and family commitment. This review points out diagnostic differences compared to adults and focuses on current therapy for selected common pediatric sleep disorders including sleep disordered breathing/ obstructive sleep apnea, narcolepsy, and restless legs syndrome. Other common pediatric sleep disorders, such as insomnia and parasomnias, are not covered.

Update on emerging drugs for insomnia EXPERT OPINION ON EMERGING DRUGS Sullivan, S. 2012; 17 (3): 295-298


In recent years, there has been no evidence that the problem of chronic insomnia has faded in the least in US adults; on the contrary, a recent estimate of annual lost productivity due to insomnia was $63.2 billion dollars. However, the proportion of insomniacs who are treated continues to be low, indicating the need for continued development and dissemination of effective therapies. Hypnotic drug development has arguably become more focused in recent years, particularly upon the highly anticipated novel target, the orexin (hypocretin) system. Merck's suvorexant (MK-4305) is the first compound of the so-called dual orexin receptor antagonist (DORA) class expected to be submitted for FDA approval, with a new drug application anticipated in 2012. While there has also been some new activity in the modulation of well-characterized targets with well-characterized agents, such as CNS histamine receptors with low-dose doxepin, a decades-old antidepressant and GABA(A) with sublingual zolpidem, experience with melatonin and serotonin modulators suggests that other targets also exist. Diversifying insomnia drug targets may expand possibilities for customizing hypnotic administration to individualized patient presentation and mechanistic underpinnings. In addition, it may offer improved avenues for combining medications with non-drug treatments such as cognitive behavioral therapy for insomnia (CBT-I).

Narcolepsy in adolescents. Adolescent medicine: state of the art reviews Sullivan, S. S. 2010; 21 (3): 542-?


Narcolepsy is a disorder of children and adolescence, but until recently it was often not identified until adulthood, with a reported time from onset to diagnosis of about a decade. This disorder affects approximately 0.05% of the population and starts in childhood and adolescence about half of the time. With narcolepsy, the boundaries between wake, sleep, and dreams are blurred. The cardinal features of narcolepsy-cataplexy are daytime somnolence, cataplexy (sometimes occurring long after onset of sleepiness), sleep paralysis, and hypnagogic hallucinations. Weight gain, disturbed nocturnal sleep, and social/school functional changes are common; reactive substance use to maintain wakefulness during the day may also be seen. Males and females are equally affected. It is classically associated with HLA DQB1*0602, the most specific genetic marker for narcolepsy across all ethnic groups. CSF hypocretin has recently been found to be depleted in this disorder, and late-breaking data support that the disease is caused by autoimmune destruction of hypocretin-producing neurons in the hypothalamus. There is no known cure for narcolepsy. Therapies include behavioral/ scheduling modification, medications to combat daytime sleepiness and cataplexy, and treatment of concomitant disorders leading to daytime sleepiness. The differential diagnosis for this disorder should include other disorders of excessive daytime sleepiness with a proclivity toward onset in adolescence, such as delayed sleep phase syndrome, obstructive sleep apnea, and insufficient sleep time; substance use; and less commonly neurologic disorders such as Klein Levin syndrome, Prader-Willi syndrome, and others. Immunomodulator therapy and hypocretin replacement are proposed therapies that hold promise for the future.

Insomnia Pharmacology MEDICAL CLINICS OF NORTH AMERICA Sullivan, S. S. 2010; 94 (3): 563-?


Insomnia is not only the most common sleep disorder in the population, it is a frequent complaint heard overall by primary care physicians and specialists alike. Given the high prevalence of this disorder, its tendency to persist, and the frequency with which patients complain of symptoms in practice, it is imperative to have an understanding of basic sleep-wake mechanisms and the evolving field of pharmacologic approaches to enhance sleep. Currently, pharmacologic approaches are among the most widely used therapies for insomnia. This article reviews sleep-wake mechanisms, the neuroanatomic targets for sleep and wake-promoting agents, and discusses currently used agents to promote sleep and investigational hypnotics.

Emerging drugs for insomnia: new frontiers for old and novel targets EXPERT OPINION ON EMERGING DRUGS Sullivan, S. S., Guilleminault, C. 2009; 14 (3): 411-422


Insomnia is the most prevalent sleep disorder, with up to 50% of the US adult population reporting symptoms of insomnia on a weekly basis and approximately 12% with insomnia disorder. Comorbid conditions such as depression and anxiety are frequent. Insomnia is more common with older age, female gender and socioeconomic status. Traditionally, therapy has focused on GABA(A) receptor agonists, and off-label antidepressant and antihistamine use.With increased understanding of complex neural networks involved in sleep and wake, hypnotics are being developed to target a broader variety of receptors with increasing selectivity. This review summarizes promising compounds in Phase II and III trials with evidence supporting efficacy for treatment of insomnia.5-HT(2A) and 5-HT(2C) antagonists, melatonergic (MT1/MT2) agonists, orexin receptor (OX1/OX2) antagonists, as well as GABA(A) receptor agonists are reviewed and summarized. Data are collected from PubMed and Pharmaprojects database searches, company websites, recent scientific meeting presentations and abstracts.A variety of drugs targeting several pathways, including GABA(A) agonism, MT1/MT2 agonism, 5-HT(2A) antagonism, OX1/OX2 antagonism and others, are in Phase II and III trials. More work should be done to understand the impact of these drugs in certain populations and in the context of comorbid conditions.

Multiple Sleep Latency Test and Maintenance of Wakefulness Test CHEST Sullivan, S. S., Kushida, C. A. 2008; 134 (4): 854-861


Excessive daytime sleepiness and fatigue are common complaints in the sleep clinic. The objective evaluation and quantification of these symptoms is important for both the diagnosis of underlying health problems and for gauging treatment response. The multiple sleep latency test measures physiologic sleepiness, whereas the maintenance of wakefulness test (MWT) aims to measure manifest sleepiness. Neither test correlates well with subjective measures of sleep such as the Epworth sleepiness scale and the Stanford sleepiness scale. Although in the past methodological testing differences existed, in 2005 updated practice parameters were published, promoting the standardization of testing procedures. In recent years, there has been an effort to document daytime sleepiness when associated with occupational risk. However, these laboratory-based tests may not reflect or predict real-life experience. Normative data for both tests, particularly the MWT, are limited, and are inadequate for the evaluation of pediatric patients, shift workers, and others.

Nasal obstruction in children with sleep-disordered breathing ANNALS ACADEMY OF MEDICINE SINGAPORE Sullivan, S., Li, K., Guilleminault, C. 2008; 37 (8): 645-648


Nasal obstruction secondary to pathological enlargement of inferior nasal turbinates contributes to sleep-disordered breathing (SBD) in prepubertal children, but treatments designed to address turbinate enlargement are often not performed. The aims of these studies are: (1) to appreciate the contribution to SDB of untreated enlarged nasal turbinates in prepubertal children; and (2) to report our experience with treatment of enlarged nasal turbinates in young children with SDB.Children with enlarged nasal turbinates who underwent adenotonsillectomy (T&A) had significantly less improvement in postoperative apnoea-hypopnoea index (AHI) compared to those treated with concomitant turbinate reduction. Children in the untreated turbinate hypertrophy group subsequently underwent radiofrequency ablation of the inferior nasal turbinates; following this procedure, AHI was no different than AHI of those without hypertrophy.In an analysis of safety and effectiveness of radiofrequency treatment of the nasal turbinates, we found the procedure to be a well-tolerated component of SDB treatment.We conclude that radiofrequency (RF) treatment of inferior nasal turbinates is a safe and effective treatment in young prepubertal children with SDB. When indicated, it should be included in the treatment plan for prepubertal children with SDB. However, the duration of effectiveness is variable and therapy may need to be repeated if turbinate hypertrophy recurs.
