RESUMO

About 20% of adults experience excessive daytime sleepiness or severe fatigue. Causes include somatic conditions, psychiatric disorders, and medication or drug use. Treatment depends on the underlying cause. If sleepiness persists despite optimal treatment of the underlying condition, exclusion of other causes, and behavioral interventions, wakefulness-promoting agents may be considered. However, no established pharmacological strategy exists for symptomatic treatment. Modafinil and stimulants like methylphenidate may offer some benefit based on experiences with narcolepsy or idiopathic hypersomnia. Studies in specific patient groups (e.g., multiple sclerosis, Parkinson's disease, traumatic brain injury, cancer-related fatigue) show variable results. The use of wakefulness-promoting agents is discouraged for addressing unexplained fatigue, as seen in the context of chronic fatigue syndrome.

RESUMO

Eugeroics are a relatively new class of wakefulness-promoting agents. Thegroup includes adrafinil, modafinil and armodafinil. Modafinil is the most widely used and the best studied agent. Indications for the use of modafinil include the treatment of narcolepsy, shift-work sleep disorders and excessive daytime sleepiness associated with obstructive sleep apnea. Many studies show the utility of modafinil and armodafinil in the treatment of depression - both in monotherapy andas potentiation therapy if needed. Modafinil has proven to be effective in the treatment of residual symptoms of unipolar and bipolar depression such as fatigue, excessive sleepiness and some cognitive impairment. Research on armodafinil points to its effectiveness mainly in augmentation therapy of depression in the course of bipolar disorder. There are also reports on the effectiveness of eugeroics in special cases - seasonal depression, atypical depression with hyperphagia, apathy in the course of depression or as an isolated symptom, cancer-related fatigue in patients receiving chemotherapy, fatigue and excessive sleepiness in neurological diseases. Eugeroics due to their high selectivity of action in the CNS have a low addictive potential compared with other stimulants. The risk of manic switch is comparable to placebo. In general, they are well-tolerated and safe. The purpose of this paper is to review the literature on the use of eugeroics in the treatment of affective disorders.

RESUMO

OBJECTIVES: We investigated the management of travel fatigue and jet lag in athlete populations by evaluating studies that have applied non-pharmacological interventions (exercise, sleep, light and nutrition), and pharmacological interventions (melatonin, sedatives, stimulants, melatonin analogues, glucocorticoids and antihistamines) following long-haul transmeridian travel-based, or laboratory-based circadian system phase-shifts. DESIGN: Systematic review Eligibility criteria Randomised controlled trials (RCTs), and non-RCTs including experimental studies and observational studies, exploring interventions to manage travel fatigue and jet lag involving actual travel-based or laboratory-based phase-shifts. Studies included participants who were athletes, except for interventions rendering no athlete studies, then the search was expanded to include studies on healthy populations. DATA SOURCES: Electronic searches in PubMed, MEDLINE, CINAHL, Google Scholar and SPORTDiscus from inception to March 2019. We assessed included articles for risk of bias, methodological quality, level of evidence and quality of evidence. RESULTS: Twenty-two articles were included: 8 non-RCTs and 14 RCTs. No relevant travel fatigue papers were found. For jet lag, only 12 athlete-specific studies were available (six non-RCTs, six RCTs). In total (athletes and healthy populations), 11 non-pharmacological studies (participants 600; intervention group 290; four non-RCTs, seven RCTs) and 11 pharmacological studies (participants 1202; intervention group 870; four non-RCTs, seven RCTs) were included. For non-pharmacological interventions, seven studies across interventions related to actual travel and four to simulated travel. For pharmacological interventions, eight studies were based on actual travel and three on simulated travel. CONCLUSIONS: We found no literature pertaining to the management of travel fatigue. Evidence for the successful management of jet lag in athletes was of low quality. More field-based studies specifically on athlete populations are required with a multifaceted approach, better design and implementation to draw valid conclusions. PROSPERO registration number The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO: CRD42019126852).

RESUMO

OSA is a highly prevalent sleep disorder, and subjective excessive daytime sleepiness (EDS) is the cardinal symptom for which many individuals seek medical advice. Positive airway pressure (PAP) devices, first-line treatment for OSA, eliminates EDS in most patients. However, a subset of patients suffers from persistent EDS despite adherence to therapy. Multiple conditions, some reversible, could account for the residual sleepiness and need to be explored, requiring detailed history, review of PAP data from the smart card, and sometimes additional testing. When all known causes of EDS are excluded, in adequately treated subjects, the purported mechanisms could relate to long-term exposure to the OSA-related sleep fragmentation, sleep deprivation, and hypoxic injury to the arousal system, shifts in melatonin secretion, or altered microbiome. Independent of the mechanism, in well-treated OSA, pharmacological therapy with approved drugs can be considered. Modafinil is commonly prescribed to combat residual EDS, but more recently two drugs, solriamfetol, a dual dopamine-norepinephrine reuptake inhibitor, and pitolisant, a histamine H3 receptor inverse agonist, were approved for EDS. Solriamfetol has undergone randomized controlled trials for treatment of EDS associated with both OSA and narcolepsy, exhibiting robust efficacy. Solriamfetol is renally excreted, with no known drug interactions. Pitolisant, which is nonscheduled, has undergone multiple RCTs in narcolepsy, showing improvement in subjective and objective EDS and one OSA trial showing improvement in subjective EDS.

RESUMO

OBJECTIVES: To examine sleep-promoting and wake-promoting drug use in police officers and associations between their use and health (excessive sleepiness, stress and burnout), performance (fatigue-related errors) and safety (near-crashes) outcomes, both alone and in combination with night-shift work. DESIGN: Cross-sectional survey. SETTING: Police officers from North America completed the survey either online or via paper/pencil at a police station. PARTICIPANTS: 4957 police participated, 3693 online (91.9%, participation rate) and 1264 onsite (cooperation rate 63.1%). MAIN OUTCOME MEASURES: Sleep-promoting and wake-promoting drug use, excessive sleepiness, near-crash motor vehicle crashes, dozing while driving, fatigue errors, stress and burnout. RESULTS: Over the past month, 20% of police officers reported using sleep-promoting drugs and drugs causing sleepiness, while wake-promoting agents were used by 28% of police (5% used wake-promoting drugs, 23% used high levels of caffeine and 4% smoked to stay awake). Use of sleep-promoting drugs was associated with increased near-crashes (OR=1.61; 95% CI 1.21 to 2.13), fatigue-related errors (OR=1.75; 95% CI 1.32 to 2.79), higher stress (OR=1.41; 95% CI 1.10 to 1.82), and higher burnout (OR=1.83; 95% CI 1.40 to 2.38). Wake-promoting drug use, high caffeine and smoking to stay awake were associated with increased odds of a fatigue-related error, stress and burnout (ORs ranging from 1.68 to 2.56). Caffeine consumption was common, and while smoking was not, of those participants who did smoke, one-in-three did so to remain awake. Night-shift work was associated with independent increases in excessive sleepiness, near-crashes and fatigue-related errors. Interactions between night-shift work and wake-promoting drug use were also found for excessive sleepiness. CONCLUSIONS: Police who use sleep-promoting and wake-promoting drugs, especially when working night shifts, are most vulnerable to adverse health, performance and safety outcomes. Future research should examine temporal relationships between shift work, drug use and adverse outcomes, in order to develop optimal alertness management strategies.

RESUMO

The wake-promoting drug Modafinil has been used for treatment of sleep disorders, such as Narcolepsy, excessive daytime sleepiness and sleep apnea, due to its stimulant action. Despite the known effect of Modafinil on brain neurochemistry, particularly on brain dopamine system, recent evidence support an immunomodulatory role for Modafinil treatment in neuroinflammatory models. Here, we aimed to study the effects of in vitro and in vivo Modafinil treatment on activation, proliferation, cell viability, and cytokine production by immune cells in splenocytes culture from mice. The results show that in vitro treatment with Modafinil increased Interferon (IFN)-γ, Interleukin (IL)-2 and IL-17 production and CD25 expression by T cells. In turn, in vivo Modafinil treatment enhanced splenocyte production of IFN-γ, IL-6 and tumor necrosis factor (TNF), and increased the number of IFN-γ producing cells. Next, we addressed the translational value of the observed effects by testing PBMCs from Narcolepsy type 1 patients that underwent Modafinil treatment. We reported increased number of IFN-γ producing cells in PBMCs from Narcolepsy type 1 patients following continuous Modafinil treatment, corroborating our animal data. Taken together, our results show, for the first time, a pro-inflammatory action of Modafinil, particularly on IFN-mediated immunity, in mice and in patients with Narcolepsy type 1. The study suggests a novel effect of this drug treatment, which should be taken into consideration when given concomitantly with an ongoing inflammatory or autoimmune process.

RESUMO

Modafinil (MOD) is a wakefulness-inducing compound prescribed for treatment of excessive daytime sleepiness as a consequence of sleep disturbances such as shift work sleep disorder, obstructive sleep apnea, restless leg syndrome, or narcolepsy. While providing effective results in patients with sleepiness, MOD also produces positive outcomes in the management of fatigue associated with different conditions including depression, cancer, or tiredness in military personnel. Although there is clear evidence of the stimulant effects of MOD, current data also show that administration of this drug apparently induces positive neurobiological effects, such as improvement in memory. However, serious concerns have been raised since some reports have suggested MOD dependence. Taken together, these findings highlight the need to characterize the changes induced by MOD which have been observed in several neurobiological functions. Moreover, further work should follow up on the likely long-term effects of this drug if used for treatment of drowsiness and tiredness. Here, we review and summarize recent findings of the medical uses of MOD in the management of sleepiness and fatigue associated with depression or cancer as well as exhaustion in military personnel. We also discuss the available literature related with the cognitive enhancing properties of this stimulant, as well as what is known and unknown about MOD addiction.

RESUMO

ABSTRACT: Disorders of consciousness may follow brain injury, due to impairments of wakefulness and/or awareness. Polysomnography can identify elements that may be ascribed to impairments of specific neuroanatomical areas. Recognizing which impairments affect each patient is crucial for diagnosis, prognosis, and to select an appropriate therapy. We present a pediatric case of insufficient wakefulness in a patient with severe disability following a pilocytic astrocytoma. Polysomnography was crucial for diagnosis, as it detected a well-structured pattern with daytime sleep initiations in the REM sleep phase. Treatment with modafinil was successful, as confirmed by polysomnography, leading to partial recovery of the patient's consciousness and communication ability. We suggest that polysomnography is a useful diagnostic tool to direct the pharmacotherapy and rehabilitation of states of reduced consciousness.

RESUMO

IMPORTANCE: Cancer-related fatigue (CRF) remains one of the most prevalent and troublesome adverse events experienced by patients with cancer during and after therapy. OBJECTIVE: To perform a meta-analysis to establish and compare the mean weighted effect sizes (WESs) of the 4 most commonly recommended treatments for CRF-exercise, psychological, combined exercise and psychological, and pharmaceutical-and to identify independent variables associated with treatment effectiveness. DATA SOURCES: PubMed, PsycINFO, CINAHL, EMBASE, and the Cochrane Library were searched from the inception of each database to May 31, 2016. STUDY SELECTION: Randomized clinical trials in adults with cancer were selected. Inclusion criteria consisted of CRF severity as an outcome and testing of exercise, psychological, exercise plus psychological, or pharmaceutical interventions. DATA EXTRACTION AND SYNTHESIS: Studies were independently reviewed by 12 raters in 3 groups using a systematic and blinded process for reconciling disagreement. Effect sizes (Cohen d) were calculated and inversely weighted by SE. MAIN OUTCOMES AND MEASURES: Severity of CRF was the primary outcome. Study quality was assessed using a modified 12-item version of the Physiotherapy Evidence-Based Database scale (range, 0-12, with 12 indicating best quality). RESULTS: From 17 033 references, 113 unique studies articles (11 525 unique participants; 78% female; mean age, 54 [range, 35-72] years) published from January 1, 1999, through May 31, 2016, had sufficient data. Studies were of good quality (mean Physiotherapy Evidence-Based Database scale score, 8.2; range, 5-12) with no evidence of publication bias. Exercise (WES, 0.30; 95% CI, 0.25-0.36; P < .001), psychological (WES, 0.27; 95% CI, 0.21-0.33; P < .001), and exercise plus psychological interventions (WES, 0.26; 95% CI, 0.13-0.38; P < .001) improved CRF during and after primary treatment, whereas pharmaceutical interventions did not (WES, 0.09; 95% CI, 0.00-0.19; P = .05). Results also suggest that CRF treatment effectiveness was associated with cancer stage, baseline treatment status, experimental treatment format, experimental treatment delivery mode, psychological mode, type of control condition, use of intention-to-treat analysis, and fatigue measures (WES range, -0.91 to 0.99). Results suggest that the effectiveness of behavioral interventions, specifically exercise and psychological interventions, is not attributable to time, attention, and education, and specific intervention modes may be more effective for treating CRF at different points in the cancer treatment trajectory (WES range, 0.09-0.22). CONCLUSIONS AND RELEVANCE: Exercise and psychological interventions are effective for reducing CRF during and after cancer treatment, and they are significantly better than the available pharmaceutical options. Clinicians should prescribe exercise or psychological interventions as first-line treatments for CRF.

RESUMO

PURPOSE: Cancer-related insomnia is associated with diminished quality of life (QOL), suggesting that improvement in insomnia may improve QOL in cancer survivors. Cognitive behavioral therapy for insomnia (CBT-I) has been shown to improve insomnia, but less is known regarding its effect on QOL and whether improvement in insomnia corresponds to improved QOL. The present analysis examines the effects of CBT-I, with and without armodafinil, on QOL both directly and indirectly through improvements of insomnia. METHODS: This is an analysis of 95 cancer survivors for a specified secondary aim of a four-arm randomized controlled trial assessing the combined and individual effects of CBT-I and armodafinil to improve insomnia. QOL and insomnia severity were assessed before, during the intervention, at post-intervention, and 3 months later by Functional Assessment of Cancer Therapy-General and Insomnia Severity Index, respectively. RESULTS: Mean change in QOL from pre- to post-intervention for CBT-I + placebo, CBT-I + armodafinil, armodafinil, and placebo was 9.6 (SE = 1.8; p < 0.0001), 11.6 (SE = 1.8; p < 0.0001), -0.2 (SE = 3.2; p = 0.964), and 3.3 (SE = 2.0; p = 0.124), respectively. ANCOVA controlling for pre-intervention scores showed that participants receiving CBT-I had significantly improved QOL at post-intervention compared to those not receiving CBT-I (p < 0.0001, effect size = 0.57), with benefits being maintained at the 3-month follow-up. Path analysis revealed that this improvement in QOL was due to improvement in insomnia severity (p = 0.002), and Pearson correlations showed that changes in QOL from pre- to post-intervention were significantly associated with concurrent changes in insomnia severity (r = -0.56; p < 0.0001). Armodafinil had no effect on QOL for those who did or did not receive it (p = 0.976; effect size = -0.004). CONCLUSION: In cancer survivors with insomnia, CBT-I resulted in clinically significant improvement in QOL via improvement in insomnia. This improvement in QOL remained stable even 3 months after completing CBT-I. IMPLICATIONS FOR CANCER SURVIVORS: Considering the high prevalence of insomnia and its detrimental impact on QOL in cancer survivors and the effectiveness of CBT-I in alleviating insomnia, it is important that evidence-based non-pharmacological sleep interventions such as CBT-I be provided as an integral part of cancer care.

RESUMO

BACKGROUND: Fatigue in military operations leads to safety and operational problems due to a decrease in alertness and performance. The primary method of counteracting the effects of sleep deprivation is to increase nightly sleep time, which in operational situations is not always feasible. History has taught us that surgeons and surgical teams are finite resources that cannot operate on patients indefinitely. METHODS: A systematic review was conducted using the search terms 'sleep' and 'deprivation' examining the impact of sleep deprivation on cognitive performance in military surgical teams. Studies examining outcomes on intensive care patients and subjects with comorbidities were not addressed in this review. RESULTS: Sleep deprivation in any 'out-of-hours' surgery has a significant impact on overall morbidity and mortality. Sleep deprivation in surgeons and surgical trainees negatively impacts cognitive performance and puts their own and patients' health at risk. All published research lacks consensus when defining 'sleep deprivation' and 'rested' states. It is recognised that it would be unethical to conduct a well-designed randomised controlled trial, to determine the effects of fatigue on performance in surgery; however, there is a paucity between surrogate markers and applying simulated results to actual clinical performance. This requires further research. Recommended methods of combating fatigue include: prophylactically 'sleep-banking' prior to known periods of sleep deprivation, napping, use of stimulant or alerting substances such as modafinil, coordinated work schedules to reduce circadian desynchronisation and regular breaks with enforced rest periods. CONCLUSIONS: A forward surgical team will become combat-ineffective after 48 hours of continuous operations. This systematic review recommends implementing on-call periods of no more than 12 hours in duration, with adequate rest periods every 24 hours. Drug therapies and sleep banking may, in the short term, prevent negative effects of acute sleep deprivation.

RESUMO

STUDY OBJECTIVES: This study involves the analysis of a secondary outcome of a trial examining whether cognitive behavior therapy for insomnia (CBT-I), a wake-promoting medication (armodafinil), or both results in greater improvement in prospectively assessed sleep continuity and daytime sleepiness than a placebo-alone group among a heterogeneous group of cancer survivors. Whether or not armodafinil alone, and/or when combined with CBT-I, affected adherence with CBT-I was evaluated. DESIGN: This study is a randomized, placebo-controlled, clinical trial. SETTING: This study was conducted at two northeastern academic medical centers. PARTICIPANTS: Eighty-eight cancer survivors with chronic insomnia were recruited between October 2008 and November 2012. Participants were assigned to one of four conditions: 1) CBT-I and placebo (CBT-I+P); 2) CBT-I and armodafinil (CBT-I + A); 2) armodafinil alone (ARM); or 4) placebo alone (PLA). INTERVENTIONS: CBT-I was delivered in seven weekly individual therapy sessions (three in person, four via telephone). The armodafinil dosage was 50 mg BID. MEASUREMENTS AND RESULTS: Sleep continuity was measured with daily sleep diaries assessing sleep latency (SL), wake after sleep onset (WASO), and total sleep time (TST). The Epworth Sleepiness Scale (ESS) measured daytime sleepiness. Compared to the PLA group, the CBT-I+P and CBT-I+A groups reported a significant reduction in SL with effect sizes of 0.67 and 0.58, respectively. A significant reduction was observed in WASO in the CBT-I+A group with an effect size of 0.64. An increasing trend of TST was observed in the CBT-I+P, CBT-I+A, and PLA groups, but not in the ARM group. No statistically significant reductions in daytime sleepiness (ESS) were observed for any of the groups. CONCLUSION: CBT-I alone and in combination with armodafinil caused significant improvement in sleep continuity. The addition of armodafinil did not appear to improve daytime sleepiness or enhance adherence to CBT-I.

RESUMO

BACKGROUND: Fatigue is a common and disabling symptom in people with a primary brain tumour (PBT). The effectiveness of interventions for treating clinically significant levels of fatigue in this population is unclear. OBJECTIVES: To assess the effectiveness and safety of pharmacological and non-pharmacological interventions for adults with PBT and high levels of fatigue. SEARCH METHODS: In March 2016, we searched the Cochrane Register of Controlled Trials (CENTRAL), MEDLINE, PsycINFO and CINAHL and checked the reference lists of included studies. We also searched relevant conference proceedings, searched for ongoing trials via ClinicalTrials.gov and contacted major co-operative groups with trials in this area. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that investigated any pharmacological or non-pharmacological intervention in adults with PBT and fatigue, where fatigue was the primary outcome measure. We restricted inclusion specifically to studies that enrolled only participants with clinically significant levels of fatigue. DATA COLLECTION AND ANALYSIS: Three review authors (JD, SYK, DC) independently evaluated search results, extracted data from selected studies and carried out a bias risk assessment. We extracted data on fatigue, cognition, mood, quality of life and adverse events outcomes. MAIN RESULTS: We identified nine studies. We excluded eight of these as they did not restrict participation to people with high fatigue. The single eligible trial investigated the use of modafinil compared to placebo. Although this study found a significant improvement over time in the primary outcome of fatigue, the improvement occurred after both modafinil and placebo with no significant difference in response between the two groups. The included trial did not reach its planned recruitment target and therefore may not, in practice, have been adequately powered to detect a difference. The trial was at a low risk of bias across most areas. There was an unclear risk of bias related to the use of mean imputation because the investigators did not analyse the impact of imputation on the results. AUTHORS' CONCLUSIONS: There was insufficient evidence to draw reliable and generalisable conclusions regarding potential effectiveness or harm of any pharmacological or non-pharmacological treatments for fatigue in people with PBT. More research is needed on how best to treat people with brain tumours with high fatigue.

RESUMO

BACKGROUND: Fatigue is common among glioma patients undergoing radiotherapy (RT) and impacts quality of life (QOL). We evaluated whether armodafinil, a wakefulness-promoting medication, improves fatigue in glioma patients undergoing RT. METHODS: Eligibility criteria included age ≥18 years, Karnofsky performance status ≥60, and grade 2-4 glioma undergoing RT to a total dose of 50-60 Gy. Patients were randomized 1:1 to armodafinil or placebo for 8 weeks beginning within 10 days of starting RT. Fatigue and QOL were assessed at baseline, day 22, day 43, and day 56 with the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F), the Functional Assessment of Cancer Therapy - General (FACT-G), the Brief Fatigue Inventory (BFI), and the Cancer Fatigue Scale (CFS). The primary aim was to detect a difference in the 42-day change in FACIT-F fatigue subscale between the 2 groups using a 2-sample Wilcoxon statistic. RESULTS: We enrolled 81 patients total (42 armodafinil and 39 placebo). Armodafinil did not significantly improve fatigue or QOL based on the 42-day change in FACIT-F fatigue subscale, FACT-G, CFS, or BFI. Further analysis suggests no difference between the arms even after accounting for the potential bias of missing data. Treatment was well tolerated with few grade 3 or 4 toxicities. CONCLUSIONS: While treatment was well-tolerated, an 8-week course of armodafinil did not improve fatigue or QOL in glioma patients undergoing RT in this pilot study. Further studies are needed to determine whether pharmacologic treatment improves fatigue in glioma patients undergoing RT.

RESUMO

OBJECTIVES: To evaluate the impact of modafinil on "free" and "cued" recall of clinical information in fatigued but nonsleep-deprived clinicians. SUMMARY BACKGROUND DATA: Despite attempts to minimize sleep deprivation through redesign of the roster of residents and staff surgeons, evidence suggests that fatigue remains prevalent. The wake-promoting agent modafinil improves cognition in the sleep-deprived fatigued state and may improve information recall in fatigued nonsleep-deprived clinicians. METHODS: Twenty-four medical undergraduates participated in a double-blind, parallel, randomized controlled trial (modafinil-200 mg:placebo). Medication was allocated 2 hours before a 90-minute fatigue-inducing, continuous performance task (dual 2-back task). A case history memorization task was then performed. Clinical information recall was assessed as "free"(no cognitive aids) and "cued"(using aid memoirs). Open and closed cues represent information of increasing specificity to aid the recall of clinical information. Fatigue was measured objectively using the psychomotor vigilance task at induction, before and after the dual 2-back task. RESULTS: Modafinil decreased false starts and lapses (modafinil = 0.50, placebo = 9.83, P < .05) and improved psychomotor vigilance task performance (Decreased Performance, modafinil = 0.006, placebo = 0.098, P < .05). Modafinil improved free information recall (modafinil = 137.8, placebo = 106.0, P < .01). There was no significant difference between groups in the amount of information recalled with open (modafinil = 62.3, placebo = 52.8, P = .1) and closed cues (modafinil = 80.1, placebo = 75.9, P = .3). CONCLUSION: Modafinil attenuated fatigue and improved free recall of clinical information without improving cue-based recall under the design of our experimental conditions. Memory cues to aid retrieval of clinical information are convenient interventions that could decrease fatigue-related error without adverse effects of the neuropharmacology.

RESUMO

PURPOSE: Fatigue is a prevalent, distressing side effect of cancer and cancer treatment which commonly coexists with insomnia. Cognitive behavioral therapy for insomnia (CBT-I) has been shown to improve insomnia in cancer patients, but less is known about its ability to impact fatigue. This work is the analysis for a secondary aim of a four-arm randomized controlled trial (RCT) study assessing the combined and comparative effect of CBT-I and a wakefulness-promoting agent, armodafinil (A), to improve sleep and daytime functioning in cancer survivors. Herein, we examine the effect of CBT-I, with and without A, on fatigue in cancer survivors. PATIENTS AND METHODS: This study was a four-arm factorial study with CBTI-I (yes/no) versus A (yes/no). It consisted of 96 cancer survivors (average age 56 years; 88 % female; 68 % breast cancer). Fatigue was assessed by the brief fatigue inventory (BFI) and the FACIT-Fatigue scale. The analysis assessed the additive effects of CBT-I and A and possible non-additive effects where the effect of CBT-I changes depending on the presence or absence of A. RESULTS: Analyses adjusting for baseline differences showed that CBT-I improved fatigue as measured by two separate scales (BFI: P = 0.002, Std. error = 0.32, effect size (ES) = 0.46; FACIT-Fatigue: P < 0.001, Std. error = 1.74, ES = 0.64). Armodafinil alone did not show a statistically significant effect on fatigue levels (all Ps > 0.40) nor did the drug influence the efficacy of CBT-I. Structural equation analysis revealed that reductions in insomnia severity were directly responsible for improving cancer-related fatigue. CONCLUSIONS: CBT-I with and without armodafinil resulted in a clinically and statistically significant reduction of subjective daytime fatigue in cancer survivors with chronic insomnia. Armodafinil did not improve cancer-related fatigue (CRF) and did not change the efficacy of CBT-I. Patients reporting CRF should be screened and, if indicated, treated for insomnia as part of a comprehensive fatigue management program.

RESUMO

OBJECTIVE: The aim of this study was to examine the effect of modafinil on depression via a secondary data analysis of a randomized clinical trial of modafinil for fatigue in cancer patients. The primary aim is to elucidate factors that contributed to the effectiveness of modafinil in the parent trial. METHODS: Five hundred forty-one cancer patients receiving chemotherapy and experiencing fatigue (Brief Fatigue Inventory [BFI] item 3 of ≥3) were randomized to receive 200 mg modafinil (n = 260) or placebo (n = 281) daily from baseline (cycle 2) to posttest (cycle 4). Patients completed the Center for Epidemiological Studies-Depression Scale (CES-D) and Profile of Mood States depression-dejection subscale at baseline and posttest. We used linear regression to address the hypothesis that modafinil would be associated with reduced depression, particularly in those experiencing severe fatigue (BFI ≥7). RESULTS: Modafinil did not have a significant effect on depression, even for those patients with severe fatigue. However, for subjects with severe fatigue (BFI ≥7), those receiving modafinil had lower depression scores than did control subjects. Modafinil significantly moderated the relationship between baseline fatigue and CES-D total scores (P = 0.04) and was marginally significant as a moderator for the relationship between baseline fatigue and Profile of Mood States depression-dejection subscale scores (P = 0.07). Modafinil also significantly moderated the relationship between baseline fatigue and CES-D positive affect subscale scores (P = 0.003), but not CES-D somatic, negative affect, or interpersonal subscale scores. CONCLUSIONS: Modafinil differentially impacts depression based on a patient's level of fatigue and reduced depressive symptoms only in those with extreme fatigue. This effect may be driven by increases in positive affective symptoms. These results have significant implications for intervention; in patients with high levels of fatigue, modafinil might also reduce depression. Future randomized clinical trials are needed to confirm these results.

RESUMO

As patients recover from their critical illness, the focus of intensive care unit (ICU) care becomes rehabilitation. Fatigue, excessive daytime somnolence (EDS), and depression can delay their recovery and potentially worsen outcomes. Psychostimulants, particularly modafinil (Provigil), have been shown to alleviate some of these symptoms in various patient populations, and as clinical trials are underway exploring this novel use of the drug, we present a case series of 3 patients in our institution's Thoracic Surgery Intensive Care Unit. Our 3 patients were chosen as a result of their fatigue, EDS, and/or depression, which prolonged their ICU stay and precluded them from participating in physical therapy, an integral component of the rehabilitative process. The patients were given 200 mg of modafinil each morning to increase patient wakefulness, encourage their participation, and enable a more restful sleep during the night. Although the drug was undoubtedly not the sole reason why our patients became more active, the temporal relationship between starting the drug and our patients' clinical improvement makes it likely that it contributed. Based on our observations with these patients, the known effects of modafinil, its safety profile, and the published experiences of others, we believe that modafinil has potential benefits when utilized in some critically ill patients and that the consequences of delayed patient recovery and a prolonged ICU stay may outweigh the risks of potential modafinil side effects.

RESUMO

Adult Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent psychiatric condition associated with high disability and frequent comorbidity. Current standard pharmacotherapy (methylphenidate and atomoxetine) improves ADHD symptoms in the short-term, but poor data were published about long-term treatment. In addition a number of patients present partial or no response to methylphenidate and atomoxetine. Research into the main database sources has been conducted to obtain an overview of alternative pharmacological approaches in adult ADHD patients. Among alternative compounds, amphetamines (mixed amphetamine salts and lisdexamfetamine) have the most robust evidence of efficacy, but they may be associated with serious side effects (e.g. psychotic symptoms or hypertension). Antidepressants, particularly those acting as noradrenaline or dopamine enhancers, have evidence of efficacy, but they should be avoided in patients with comorbid bipolar disorder. Finally metadoxine and lithium may be particularly suitable in case of comorbid alcohol misuse or bipolar disorder.

RESUMO

BACKGROUND: Common acute-term side effects of brain radiotherapy (RT) include fatigue, drowsiness, decreased physical functioning, and decreased quality of life (QOL). We hypothesized that armodafinil (a wakefulness-promoting drug known to reduce fatigue and increase cognitive function in breast cancer patients receiving chemotherapy) would result in reduced fatigue and sleepiness for patients receiving brain RT. METHODS: A phase II, multi-institutional, placebo-controlled randomized trial assessed feasibility of armodafinil 150 mg/day in participants receiving brain RT, from whom we obtained estimates of variability for fatigue, sleepiness, QOL, cognitive function, and treatment effect. RESULTS: From September 20, 2010, to October 20, 2012, 54 participants enrolled with 80% retention and 94% self-reported compliance. There were no grade 4-5 toxicities, and the incidence of grade 2-3 toxicities was similar between treatment arms, the most common of which were anxiety and nausea (15%), headaches (19%), and insomnia (20%). There were no statistically significant differences in end-RT or 4 week post-RT outcomes between armodafinil and placebo in any outcomes (Functional Assessment of Chronic Illness Therapy [FACIT]-Fatigue, Brief Fatigue Inventory, Epworth Sleepiness Scale, FACT-Brain, and FACIT-cognitive function). However, in participants with more baseline fatigue, those treated with armodafinil did better than those who received the placebo on the end-RT assessments for several outcomes. CONCLUSION: Armodafinil 150 mg/day was well tolerated in primary brain tumor patients undergoing RT with good compliance. While there was no overall significant effect on fatigue, those with greater baseline fatigue experienced improved QOL and reduced fatigue when using armodafinil. These data suggest that a prospective, phase III randomized trial is warranted for patients with greater baseline fatigue.
