Can triptans safely be used for airplane headache?

Rimegepant in airplane headache treatment: a case report

BACKGROUND

Airplane headache is a rare condition first identified in 2004 and subsequently included in the International Classification of Headache Disorders (Headache Classification Committee of the International Headache Society in Cephalalgia 33:629-808, 2013. https://doi.org/10.1177/0333102413485658 ). Airplane headache typically presents as intense, stabbing, unilateral pain in the frontal or orbital regions, with a severity of 8-10 on the numeric rating scale. Despite its relatively low prevalence and generally nondisabling nature, the intense pain associated with airplane headache often leads to significant anxiety and fear of flying, underscoring the need for effective treatment strategies. Currently, there are no established guidelines for the treatment of airplane headache. Various anecdotal treatments have been reported, including nasal decongestants, nonsteroidal antiinflammatory drugs, and triptans.

CASE PRESENTATION

We describe the case of a 28-years old Caucasian female patient with recurrent airplane headache successfully treated with rimegepant, a calcitonin gene-related peptide receptor antagonist, taken half an hour before plane departure. A 10-month follow-up confirmed the treatment efficacy.

CONCLUSION

This novel use of rimegepant, typically employed in migraine management, demonstrates a promising therapeutic option for airplane headache.

Efficacy of a long-term acting triptan for Headache attributed to aeroplane travel: a case report

Headache attributed to aeroplane travel (AH) is a well-defined nosological entity whose diagnostic criteria have been published in the third provisional International Classification of Headache Disorders (ICHD) and confirmed in the definitive version. Despite the severe intensity of pain, less than half of the AH cases described used medications for preventing the attack. The most frequent prophylactic therapy spontaneously used by sufferers are simple analgesics, non-steroidal anti-inflammatory drugs (NSAIDs), and nasal decongestants, achieving a complete or partial benefit in about 50% of patients. A complete response of AH to fast-acting triptans has been reported. We describe the case of a 37-year-old migrainous woman suffers from AH in about 75% of her flights who preempted the attacks by using a long-acting triptan (frovatriptan). Giving triptans' mechanism of action, an involvement of the trigemino-vascular system in the pathogenesis of AH could be advanced.

Successful Treatment of Airplane Headache with Rizatriptan: Case Report

Optimal management of airplane headache (AH) is still unresolved. A female, 53 years, complained of severe short-lasting jabbing pain attacks over the forehead and in the eyebrows, mainly on the left side, that occur during take-off and landing. Neurological, opthalmological, and otolaryngological examinations and brain MRI were normal. It was diagnosed as AH. The patient was recommended to take 10 mg rizatriptan 30 min before the flight. It resulted in a complete absence of headache during the take-off and significant decrease of pain intensity during the plane descending. Based on the flight duration (about 2.5 h) and rizatriptan pharmacokinetics, the patient was recommended to take a second dose of rizatriptan 10 mg 1 h before flight ending. The patient reported a complete absence of pain attacks during the next flights. The effectiveness of AH pain attack prevention is based on the pharmacokinetic properties of the drug, time of pain onset during flight, and the flight duration.

Sherpas, Coca Leaves, and Planes: High Altitude and Airplane Headache Review with a Case of Post-LASIK Myopic Shift

PURPOSE OF REVIEW

High altitude headache is a common neurological symptom that is associated with ascent to high altitude. It is classified by the International Classification of Headache Disorders, 3rd Edition (ICHD-3) as a disorder of homeostasis. In this article, we review recent clinical and insights into the pathophysiological mechanisms of high altitude and airplane headache. We also report a second case of post-LASIK myopic shift at high altitude exposure secondary hypoxia. Headache attributed to airplane travel is a severe typically unilateral orbital headache that usually improves after landing. This was a relative recent introduction to the ICHD-3 diagnostic criteria. Headache pain with flight travel has long been known and may have been previously considered as a part of barotrauma. Recent studies have helped identify this as a distinct headache disorder.

RECENT FINDINGS

Physiologic, hematological, and biochemical biomarkers have been identified in recent high altitude studies. There have been recent advance in identification of molecular mechanisms underlying neurophysiologic changes secondary to hypoxia. Calcitonin gene-related peptide, a potent vasodilator, has been implicated in migraine pathophysiology. Recent epidemiological studies indicate that the prevalence of airplane headache may be more common than we think in the adult as well at the pediatric population. Simulated flight studies have identified potential biomarkers. Although research is limited, there have been advances in both clinical and pathophysiological mechanisms associated with high altitude and airplane headache.

Diving Headache

This review will focus on the most recent information regarding the ICHD-3 definition of diving headache as well as other important causes of diving headache that are not listed in the ICHD-3 classification system. The paper will discuss etiology, diagnosis, and management of these disorders, focusing, when possible, on the newest research available. ICHD-3 diving headache is due to hypercapnia and is treated accordingly with oxygen. Other causes of diving headache range from decompression sickness to external compression headache to primary headache disorders, such as migraine. Correctly determining the underlying cause of the diving headache is critical to management and relies on history taking and physical exam. The pathophysiology of newly described types of diving headache, such as diving ascent headache, remains under investigation but may be related to other homeostatic headache causes, such as airplane headache. Further investigation may yield more information regarding management as well as possible insight into other headache disorders.

Prevalence of headache attributed to aeroplane travel in headache outpatient populations: An Italian multicentric survey

Background

To assess the prevalence of headache attributed to aeroplane travel (AH) in patients referred to Italian Headache Centres.

Material and method

869 consecutive patients visiting six Italian headache centres during a 6 month-period (October 2013 to March 2014) were enrolled in the survey. Among them, 136 (15.6%) had never flown and therefore were excluded from the study. The remaining 733 patients (f = 586, m = 147; age 39.1 ± 17.3) were asked about the occurrence of headache attacks during flight; those who answered the question positively filled in a detailed questionnaire that allowed the features of the attacks to be defined.

Results

Headache attacks during the flight was reported by 34/733 subjects; four presented attacks fulfilling ICHD-3 beta (1) criteria for migraine without aura and therefore were not further considered. The features of the remaining 30 (4.0%; m = 18, f = 12, age 36.4 ± 7.3) completely fulfilled the ICHD-3 beta criteria for AH. In more detail, the pain was unilateral (fronto-orbital: n = 23; fronto-parietal: n = 7; without side-shift: n = 25, with side-shift: n = 5), lasting up to 30 min in 29 subjects. All the patients reported the pain as very severe or unbearable and landing as the phase of travel in which the attack appeared. In four cases, a postictal, milder, dull headache could last up to 24 hours. Accompanying symptoms were present in eight cases (restlessness: n = 5; conjunctival injection and tearing: n = 2; restlessness + ipsilateral conjunctival injection and tearing: n = 1). The fear of experiencing further attacks negatively affected the propensity for future flights in 90.0% of subjects (n = 27). In all the patients, AH onset did not coincide with the first flight experience. Concomitant migraine without aura was diagnosed in 24, tension-type headache in four, migraine without aura + tension-type headache in two cases; none suffered from cluster headache. Five subjects reported AH on each flight, 20 in > 50% of flights, five occasionally. Despite the severe intensity of the pain, only one third of this sample spontaneously reverted to a pharmacological treatment; the most useful strategy combines a decongestant nasal spray plus the intake of a simple analgesic 30 min before the estimated attack. Spontaneous manoeuvres were applied by 18 patients (Valsalva-like: n = 12; compression: n = 2; both manoeuvres: n = 4), more often without significant improvement. These data confirm our previous finding on the clinical features of AH.

Conclusion

AH was found in 4.0% of a multicentre, large sample of patients with flight experiences. Although limited to a sample of patients followed in six Italian headache centres, to the best of our knowledge these are the first epidemiological data on AH gathered by direct interview. If properly investigated, AH seems to be a not infrequent condition, which, when diagnosed, could probably be prevented in many cases.

Headache Attributed to Aeroplane Travel: An Historical Outline

INTRODUCTION

Headache attributed to aeroplane travel (AH) is one of the new nosological entries in the International Classification of Headache Disorders (ICHD) 3 beta.

MATERIALS AND METHODS

This study retraces the history of headache related to flight, from the initial description to the modern reports, on the basis of original sources.

RESULTS

Head pain related to flight has been reported since the beginning of flight era. However, most of those early cases are easily recognized as secondary to an exceptional barotrauma and/or a sinusitis concomitant with the flight. Instead, contemporary research identified a new nosological entity, AH, which by definition occurs in normal flying conditions and in absence of any sinus pathology. Moreover, we identified recently similar forms of headache, triggered by sudden changes of external pressure (rapid descent from mountain, mountain descent headache, MDH); and ascent from diving, diving ascent headache (DAH).

CONCLUSION

Head pain related to flight has been reported since the origin of aviation, but it was caused by an exceptional barotrauma or a respiratory infection. Instead, AH occurs in normal flying conditions. Two newly identified conditions, MDH and DAH, appear to share a common pathogenetic mechanism with AH: namely the imbalance between intrasinusal and external air pressure. Therefore, we assert that an expansion of this entity of AH is something that should be considered in the next ICHD.

Headache attributed to airplane travel: diagnosis, pathophysiology, and treatment - a systematic review

BACKGROUND

Headache attributed to airplane travel, also named "airplane headache" (AH) is a headache that occurs during take-off and landing. Today, there are still uncertainties about the pathophysiology and treatment of AH. This systematic review was performed to facilitate identification of the existing literature on AH in order to discuss the current evidence and areas that remain to be investigated in AH.

METHODS

The systematic literature search was performed in 3 relevant medical databases; PubMed, Scopus, and Embase. The search yielded 220 papers and the papers were sorted based on inclusion and exclusion criteria established for this study.

RESULTS

This systematic review included 39 papers. Main findings revealed that AH attacks are clinically stereotyped and appear mostly during landing phases. The headache presents as a severe painful headache that often disappears within 30 min. The pain is unilateral and localized in the fronto-orbital region. Sinus barotrauma has been considered as the main cause of AH. Nonsteroidal anti-inflammatory drugs and triptans have been taken by passengers with AH, to relieve the headache.

CONCLUSIONS

Based on this systematic review, further studies seem required to investigate underlying mechanisms in AH and also to investigate the biological effects of nonsteroidal anti-inflammatory drugs and triptans for alleviating of AH. These studies would advance our understanding of AH pathogenesis and potential use of treatments that are not yet established.

Aeroplane headache, mountain descent headache, diving ascent headache.. Three subtypes of headache attributed to imbalance between intrasinusal and external air pressure?

Background

Headache attributed to aeroplane travel (AH) is currently codified in Chapter 10.1.2 of the International Classification of Headache Disorders 3 beta (ICHD 3 beta). After our previous papers, the investigation was enlarged to 200 patients.

Material and methods

People affected by AH contacted us by mail and agreed to fill in a detailed anonymous questionnaire that allowed a thorough definition of the headache features.

Results

This extended case series allows us to confirm most of the clinical features of AH, reported in our previously published article, and to partially modify others. New results mainly regard the higher occurrence of accompanying symptoms and the presence of a long lasting mild headache phase, usually not exceeding 24 h, that follows the short lasting acute pain, the duration of which has been confirmed as less than 30 min. Moreover, headache attacks identical to those of AH are reported in a portion of patients, triggered by the ascent during free/snorkeling or scuba diving and rapid descent from high mountains.

Conclusion

The coexistence of AH with headache triggered by different environmental factors (ascent during free/scuba diving and descent from high mountains) indicates a common causal mechanism, that is, the imbalance between intrasinusal and external air pressure. We propose to classify them together, within Chapter 10 “ Headache attributed to disorders of homoeostasis”, under a unique heading “ Headache attributed to imbalance between intrasinusal and external air pressure”.

Simulated airplane headache: a proxy towards identification of underlying mechanisms

BACKGROUND

Airplane Headache (AH) occurs during flights and often appears as an intense, short lasting headache during take-off or landing. Reports are limited on pathological mechanisms underlying the occurrence of this headache. Proper diagnosis and treatments would benefit from identification of potential pathways involved in AH pathogenesis. This study aimed at providing a simulated airplane headache condition as a proxy towards identification of its underlying mechanisms.

METHODS

Fourteen participants including 7 volunteers suffering from AH and 7 healthy matched controls were recruited after meeting the diagnostic and safety criteria based on an approved study protocol. Simulation of AH was achieved by entering a pressure chamber with similar characteristics of an airplane flight. Selected potential biomarkers including salivary prostaglandin E₂ (PGE₂), cortisol, facial thermo-images, blood pressure, pulse, and saturation pulse oxygen (SPO) were defined and values were collected before, during and after flight simulation in the pressure chamber. Salivary samples were analyzed with ELISA techniques, while data analysis and statistical tests were handled with SPSS version 22.0.

RESULTS

All participants in the AH-group experienced a headache attack similar to AH experience during flight. The non-AH-group did not experience any headaches. Our data showed that the values for PGE₂, cortisol and SPO were significantly different in the AH-group in comparison with the non-AH-group during the flight simulation in the pressure chamber.

CONCLUSION

The pressure chamber proved useful not only to provoke AH-like attack but also to study potential biomarkers for AH in this study. PGE₂, and cortisol levels together with SPO presented dysregulation during the simulated AH-attack in affected individuals compared with healthy controls. Based on these findings we propose to use pressure chamber as a model to induce AH, and thus assess new potential biomarkers for AH in future studies.

Headaches attributed to airplane travel: a Danish survey

Background

Airplane headache (AH) is a headache that occurs during take-off and landing. The pain is described as severe, unilateral, and located in the fronto-orbital region. This study aimed at investigating the incidence of AH among Scandinavian air-travelers, and to elucidating potential risk factors.

Methods

An online, Danish-survey was developed. The questionnaire consisted of 14 questions and was distributed through the Facebook-pages of Scandinavian-airlines and interest organizations. Participants reached the questionnaire through a web-link.

Results

Out of 254 responses, 89 noted that they suffered from headaches associated to airplane travel. Of the 89, 21 cases the headache was severe and limited to 30 min duration, as described in the ICH’s criteria of AH. The remaining 68 cases indicated that the headache lasted longer than 30 min. Our data demonstrated that High-Altitude Headache (HAH) is a risk factor for developing AH (p < 0.05). Triptans (19 %) and paracetamol (5 %) were reported effective to relieve AH.

Conclusion

This study indicates that up to 8.3 % of the studied population suffered from AH, with a higher incidence in those with a history of HAH. Self-medication by triptans and paracetamol were reported effective for relieving AH.

Childhood headache attributed to airplane travel: a case report

Headache attributed to airplane flights is a rare form of headache disorder. This case study describes an 11-year-old girl with recurrent, severe, frontal headaches occurring during airplane travel. The episodes were associated with dizziness and facial pallor but no additional symptoms and showed spontaneous resolution on landing. Blood tests and imaging revealed no abnormalities. The present case fulfils the criteria for airplane headache recently included in the revised edition of the International Classification of Headache Disorders (ICHD-III Beta). Only a few cases of airplane headache have been reported in children. To our knowledge, this is the fourth case. We review the current literature on this rare syndrome and discuss various proposed pathophysiological mechanisms.

Diagnosis and management of headache attributed to airplane travel

The headache attributed to airplane travel, also named "airplane headache", is characterized by the sudden onset of a severe head pain exclusively in relation to airplane flights, mainly during the landing phase. Secondary causes, such as upper respiratory tract infections or acute sinusitis, must be ruled out. Although its cause is not thoroughly understood, sinus barotrauma should be reasonably involved in the pathophysiological mechanisms. Furthermore, in the current International Classification of Headache Disorders, rapid descent from high altitude is not considered as a possible cause of headache, although the onset of such pain in airplane travellers or aviators has been well known since the beginning of the aviation era. On the basis of a survey we conducted with the courteous cooperation of people who had experienced this type of headache, we proposed diagnostic criteria to be added to the forthcoming revision of the International Classification of Headache Disorders. Their formal validation would favour further studies aimed at improving knowledge of the pathophysiological mechanisms involved and at implementing preventative measures.

Headache attributed to airplane travel ('airplane headache'): clinical profile based on a large case series

BACKGROUND

The 'headache attributed to airplane travel', also named 'airplane headache' (AH), is a recently described headache disorder that appears exclusively in relation to airplane flights, in particular during the landing phase. Based on the stereotypical nature of the attacks in all reported cases, we proposed provisional diagnostic criteria for AH in a previously published paper. Up to now 37 cases have been described in the literature.

METHODS

After our paper was disseminated via the Internet, we received several email messages from subjects around the world who had experienced such a peculiar headache. Their cooperation, by completing a structured questionnaire and allowing the direct observation of three subjects, enabled us to carry out a study on a total of 75 patients suffering from AH.

RESULTS

Our survey confirmed the stereotypical nature of the attacks, in particular with regard to the short duration of the pain (lasting less than 30 minutes in up to 95% of the cases), the clear relationship with the landing phase, the unilateral pain, the male preponderance, and the absence of accompanying signs and/or symptoms. It is conceivable to consider barotrauma as one of the main mechanisms involved in the pathophysiology of AH. The observation that the pain appears inconstantly in the majority of cases, without any evident disorder affecting the paranasal sinuses, could be consistent with a multimodal pathogenesis underlying this condition, possibly resulting in the interaction between anatomic, environmental and temporary concurrent factors.

CONCLUSIONS

This is by far the largest AH case series ever reported in the literature. The diagnostic criteria that we previously proposed proved to be valid when applied to a large number of patients suffering from this condition. We support its recognition as a new form of headache, to be included in the forthcoming update of the International Headache Society Classification, within '10. Headache attributed to disorder of homoeostasis'. Its formal validation would favour further studies aimed at improving the understanding of its pathophysiology and implementing preventative measures.
