Itch is one of the most protean manifestations of skin disease and can take a substantial physical and emotional toll on patients. For physicians, it is a frequent—if often dreaded—patient concern with a rising incidence. Lack of specific itch therapies as well as associations with multiple dermatologic conditions, including xerosis, psoriasis, atopic dermatitis, cutaneous lymphoma, contact dermatitis, and internal malignancies, make management of these itchy patients challenging and deserving of our attention. Studies evaluating patients with chronic pruritus identified a considerable impact on health-related quality of life, including development of depression, inability to perform activities of daily living, and sleep difficulties. ¹

How to Classify Itching

Itch, or pruritus, originally was defined as an unpleasant sensation that provokes the desire to scratch,² but this definition likely limits our ability to assess itch. The urge to scratch the skin to relieve the itch is sometimes a reflex of the muscles triggered by the spinal cord that can be either conscious or unconscious. If 2 patients present with itch, does the patient with more excoriated skin experience more severe itch? Conversely, does the patient who scratches less have an equivalent decrease in itch severity? Although it is tempting to quantify itch through physical signs such as excoriations, it ultimately is a subjective symptom that is difficult to assess.

Pain is another complex subjective symptom but is one that has been better studied. A previous intensity theory postulated that itch is a form of pain: low-intensity noxious stimuli are perceived as itch, while high-intensity stimuli are perceived as pain. Over time, our understanding of itch evolved, and it became clear that a specific neuronal pathway for itch also exists.³ However, the pathophysiology of itch and pain remain intertwined. Scratching may elicit pain, providing a change in sensation that replaces the itch, whereas opioid analgesics suppress pain but may worsen the itch.

We are gaining a better understanding of the biology and classification of itch, which will hopefully enable the development of new measures to accurately assess itch. Four main categories of itch currently exist: neurogenic, psychogenic, neuropathic, and pruritoceptive.⁴ Patients may have one or multiple types of itch, which can be differentiated clinically and biochemically. Neurogenic (also known as systemic) itch is transmitted via the central nervous system with possible involvement of itch-specific neurons in the spinal cord and encompasses itch associated with pruritus from other organ systems. As the term implies, psychogenic itch is associated with psychiatric disorders. Neuropathic itch is generated from the inappropriate firing of peripheral or central sensory neurons in the absence of pruritogenic stimuli, which can be seen in notalgia paresthetica, brachioradial pruritus, and postherpetic neuralgia. Pruritoceptive itch most commonly is encountered in dermatology and is associated with skin inflammation or other dermatoses.⁴

How to Assess Itch Quantitatively

There currently are 2 major questions about quantitative assessments of itch. First, how do we measure itch in studies that are designed to relieve a different skin disease that is associated with itch? Most clinical trials investigating therapeutic options for atopic dermatitis and psoriasis now include itch assessment and improvement as a secondary outcome. Second, how do we measure itch in studies that are designed with relief of itch as the primary end point? Both of these scenarios require a fundamental set of decisions. Itch clearly is a subjective experience, but it also is one that can be local, regional, generalized, or transitory. Just as with pain, an individual can be distracted from their itch to some extent and consequently experience it more acutely when there are fewer stimuli in their environment. Classically, patients will report that itching is worse at night, preventing them from sleeping. Sleep disruption previously has been demonstrated.⁵ Of course, the environment also can exacerbate itch, as dry air and in some cases humidity can flare the sensation.

Fundamentally, therefore, the questions that are asked to assess itch are incredibly relevant, and there is a matrix of possible avenues of inquiry. Should you measure the peak itch in one area or the peak itch overall? Is the duration, the frequency, or the persistence of the itching most relevant? What is the correct time frame in which to do an assessment: the last 24 hours, the last 48 hours, or the last week? Because these parameters have been so challenging, most investigators have used a visual analog scale, similar to what is used to assess pain, at a 24-hour interval to decrease recall bias. The most commonly employed tool is the itch numeric rating scale (NRS), which asks patients to rate their symptoms on a scale of 0 (no itch) to 10 (worst imaginable itch). Although the psychometric properties of the itch NRS have been validated, debate still exists as to whether the itch NRS is best administered at a specific time of day or if it should be updated to evaluate peak pruritus scores explicitly. Regardless, implementing these scales often is time consuming and burdensome in the clinical trial setting, as participants are asked to complete daily diaries at the same time each day using either paper forms or electronic tablets.

Once scores are collected, we then need to quantitate a meaningful difference in itch. For pain, there has been some acceptance of a 30% difference, or a 2-point reduction, as being clinically meaningful; however, there was substantial debate at the time of the approval of ixekizumab as to whether that was a similarly appropriate threshold for itch. Using data from ixekizumab phase 2 and phase 3 trials, a 4-point reduction in itch NRS was found to be optimal for evaluating clinically significant changes in moderate to severe psoriasis.⁶ A more recent study of the validity of the itch NRS in prurigo nodularis suggested a 1-point change was correlated with minimal clinical improvement.⁷ Thus, the interesting question of how assessment of itch varies across clinical trials and disease states needs to be raised. Psoriasis classically has been thought of as not particularly itchy, and atopic dermatitis and prurigo nodularis have been regarded as extraordinarily itchy, yet one study comparing baseline itch scores in psoriasis and atopic dermatitis suggested that the experience actually is somewhat similar.⁸

Final Thoughts

The subjective nature of itch makes NRSs our best option at this time, but the best disease severity assessment tools are objective, sensitive, and generalizable. Unfortunately, we do not have such tools available to us yet, but technology—smart devices to monitor nocturnal scratching and machine learning algorithms that use electromagnetic impact to capture motion associated with itching and scratching⁹—may offer new objective measures for itch that can be used to further validate the current itch NRS. Even if these technology-based approaches become the standard of measurement, they will certainly help us understand what we are measuring. And even better, the focus on how to develop meaningful end points around the improvement of itch will likely lead us to measure it more and drive the development of therapeutics that address the effect and consequences of this pernicious problem.

To the Editor:

Erosive lichen planus (LP) often is painful, debilitating, and resistant to topical therapy making it both a diagnostic and therapeutic challenge. We report the case of an elderly woman with isolated perianal erosive LP, a rare clinical manifestation. We also review cases of erosive perianal LP reported in the literature.

A 72-year-old woman was referred to our dermatology clinic for evaluation of multiple pruritic and painful perianal lesions of 1 year’s duration. The lesions had remained stable since onset, with no other reported lesions elsewhere on body, including the mucosae. Her medical history was notable for rheumatoid arthritis, osteoporosis, hypercholesterolemia, and hypertension. She was taking methotrexate, folic acid, abatacept, alendronate, atorvastatin, and lisinopril. The patient reported she had been using abatacept for 3 years and lisinopril for 2 years. Her primary care physician initially treated the lesions as hemorrhoids but referred her to a gastroenterologist when they failed to improve. Gastroenterology evaluated the patient, and a colonoscopy was performed with unremarkable results. Thus, she was referred to dermatology for further evaluation.

Physical examination revealed 2 tender, sharply defined, angulated erosions with irregular violaceous borders involving the perianal skin (Figure 1). A biopsy of one of the lesions was taken. Histopathologic examination revealed acanthosis of the epidermis with slight compact hyperkeratosis, scattered dyskeratotic keratinocytes, and a dense bandlike lymphohistiocytic infiltrate that obliterated the dermoepidermal junction (Figure 2). A diagnosis of perianal erosive LP was made. The patient was prescribed mometasone ointment 0.1% daily with notable improvement after 2 months.

Treatment of LP varies depending on the location and subtype of the lesions and is primarily aimed at improving symptoms. Topical corticosteroids are the standard treatment of LP; however, there is limited evidence regarding their efficacy for mucosal LP. Although randomized controlled trials assessing the efficacy of different interventions on oral erosive LP are available in the literature,¹⁵ there is a paucity of studies addressing this topic for genital or perianal LP. A review of the literature regarding perianal erosive LP suggests good response to high-potency topical steroids and calcineurin inhibitors with resolution of lesions within 3 to 4 weeks.^11,15-18

Erosive LP is a painful variant that can cause erosions, ulcerations, and scarring. It rarely is seen in the perianal region alone and presents a diagnostic challenge. Treatment with high-potency topical steroid therapy seems to be effective in the few cases that have been reported as well as in our case. More comprehensive data from randomized controlled trials would be needed to evaluate their efficacy compared to other therapies.

An increase in the use of hypofractionated radiotherapy for lung cancer has been one of the many consequences of the COVID-19 pandemic, according to initial data from the COVID-RT Lung study.

The U.K.-based study showed that patients with stage I-III lung cancer who were set to undergo radiotherapy with curative intent were more likely to receive fewer fractions at higher doses when treated between April and October 2020. During that period, 19% of patients had their radiotherapy dose or fractionation schedule changed to deviate from standard care.

In addition, 8% of patients who were set to undergo surgery ultimately received radiotherapy instead, presumably to ease pressures on already struggling intensive care services, said Kathryn Banfill, MBChB, of Christie NHS Foundation Trust in Manchester, England.

Dr. Banfill presented results from the COVID-RT Lung study at the European Lung Cancer Virtual Congress 2021 (Abstract 203MO).


 

New guidelines prompt study

When the COVID-19 pandemic began, European and joint European and North American guidelines were issued to try to ensure that lung cancer patients would continue to receive the best possible treatment under the circumstances. This included guidance on how and when to use treatments such as radiotherapy.

One U.K. guideline included recommendations on the use of hypofractionation in the COVID-19 era. The recommendations focused on altering the dosage or length of radiotherapy treatments to try to reduce the number of hospital visits, thereby reducing the risk of exposing patients to SARS-CoV-2.

“The aim of these guidelines is very much to reduce the risk to patients,” Dr. Banfill said. “These patients are often at higher risk of serious COVID-19, both as a result of their cancer and also as a result of many of the coexisting medical conditions that they have, such as COPD [chronic obstructive pulmonary disease],” she explained.

The COVID-RT Lung study was essentially born out of these guidelines. The goals of the study were to see what changes to radiotherapy practice occurred as a result of the guidelines and to assess how the changes have affected patient outcomes.
 

Changes to diagnosis and treatment

COVID-RT Lung is an ongoing, prospective study of patients with biopsy- or imaging-proven stage I–III lung cancer who were referred for, or treated with, radical radiotherapy at one of 26 oncology centers in the United Kingdom between April and October 2020.

Records on 1,117 patients were available for the initial analysis. The patients’ median age was 72 years (range, 38-93 years), and half were women.

The records showed changes to diagnostic investigations in 14% of patients (n = 160). Changes included not obtaining histology (4.6%, n = 51), not conducting nodal sampling (3.1%, n = 35), not performing pulmonary function tests (1.8%, n = 20), not conducting brain imaging (2.9%, n = 32), not performing PET/CT scans or having out-of-date scans (4.2%, n = 47), and delays in diagnosis (0.6%, n = 7).

Changes to treatment – deviations from standard care – occurred in 37% of patients (n = 415). This included 19% of patients (n = 210) having changes to radiotherapy dose or fractionation schedule, 8% (n = 86) undergoing radiotherapy instead of surgery, and 13% (n = 143) having their chemotherapy omitted or reduced.

The median number of radiotherapy fractions was 15 for patients who had their radiotherapy adjusted and 20 for those who had no treatment amendments.

“Those who had their treatment changed were more likely to have hypofractionated or ultra-hypofractionated radiotherapy,” Dr. Banfill said.

This was particularly true for patients with early-stage disease, she noted, where there was an increase in the percentage of patients getting more than 15 Gy per fraction. Even in stage III disease, there was an increased use of 3–5 Gy per fraction, although “virtually nobody” who had a change in treatment received less than 2 Gy per fraction, Dr. Banfill said.

“The changes are in line with what was reported in international recommendations,” observed Yolande Lievens, MD, PhD, of Ghent University Hospital in Belgium, who discussed the findings at the meeting.
 

Few patients had COVID-19

“It was striking to me to see that so few patients developed COVID-19 prior to radiotherapy or during radiotherapy,” Dr. Lievens noted. “This is actually something that we’ve also experienced in our setting.”

Indeed, just 15 patients (1%) were diagnosed with COVID-19, 10 of whom were diagnosed before receiving radiotherapy.

Dr. Banfill observed that the COVID-19 diagnosis had been “a reasonable time” before the patients started radiotherapy, and some had been diagnosed with lung cancer as a result of having a chest x-ray for suspected COVID-19.

Of the four patients who were diagnosed during treatment, two had their radiotherapy interrupted as a result.

The low COVID-19 rate is perhaps a result of the protective measures recommended in the United Kingdom, such as advising patients to shield from others, Dr. Banfill said.
 

Are changes to practice likely to hold?

“Part of the reason we actually stopped the data collection in October was that people were starting to go, ‘Well, is this actually a change?’ because they’d been doing it for 6 months,” Dr. Banfill observed during the discussion session.

“It was becoming almost normal for some of these hypofractionated changes. I think there is potential for these to become more embedded going forward,” she said. Data on how these changes might affect patients in the long term is going to be the focus of a future analysis.

“There is ongoing data collection on recurrence and survival and toxicity, which will hopefully provide more information on the outcomes of this patient group,” Dr. Banfill said.

The COVID-RT Lung project is supported by the NIHR Manchester Biomedical Research Centre. Dr. Banfill and Dr. Lievens reported no relevant conflicts of interest.

“The aim of these guidelines is very much to reduce the risk to patients,” Dr. Banfill said. “These patients are often at higher risk of serious COVID-19, both as a result of their cancer and also as a result of many of the coexisting medical conditions that they have, such as COPD [chronic obstructive pulmonary disease],” she explained.

The COVID-RT Lung study was essentially born out of these guidelines. The goals of the study were to see what changes to radiotherapy practice occurred as a result of the guidelines and to assess how the changes have affected patient outcomes.
 

Changes to diagnosis and treatment

COVID-RT Lung is an ongoing, prospective study of patients with biopsy- or imaging-proven stage I–III lung cancer who were referred for, or treated with, radical radiotherapy at one of 26 oncology centers in the United Kingdom between April and October 2020.

Records on 1,117 patients were available for the initial analysis. The patients’ median age was 72 years (range, 38-93 years), and half were women.

The records showed changes to diagnostic investigations in 14% of patients (n = 160). Changes included not obtaining histology (4.6%, n = 51), not conducting nodal sampling (3.1%, n = 35), not performing pulmonary function tests (1.8%, n = 20), not conducting brain imaging (2.9%, n = 32), not performing PET/CT scans or having out-of-date scans (4.2%, n = 47), and delays in diagnosis (0.6%, n = 7).

Changes to treatment – deviations from standard care – occurred in 37% of patients (n = 415). This included 19% of patients (n = 210) having changes to radiotherapy dose or fractionation schedule, 8% (n = 86) undergoing radiotherapy instead of surgery, and 13% (n = 143) having their chemotherapy omitted or reduced.

The median number of radiotherapy fractions was 15 for patients who had their radiotherapy adjusted and 20 for those who had no treatment amendments.

“Those who had their treatment changed were more likely to have hypofractionated or ultra-hypofractionated radiotherapy,” Dr. Banfill said.

This was particularly true for patients with early-stage disease, she noted, where there was an increase in the percentage of patients getting more than 15 Gy per fraction. Even in stage III disease, there was an increased use of 3–5 Gy per fraction, although “virtually nobody” who had a change in treatment received less than 2 Gy per fraction, Dr. Banfill said.

“The changes are in line with what was reported in international recommendations,” observed Yolande Lievens, MD, PhD, of Ghent University Hospital in Belgium, who discussed the findings at the meeting.
 

Few patients had COVID-19

“It was striking to me to see that so few patients developed COVID-19 prior to radiotherapy or during radiotherapy,” Dr. Lievens noted. “This is actually something that we’ve also experienced in our setting.”

Indeed, just 15 patients (1%) were diagnosed with COVID-19, 10 of whom were diagnosed before receiving radiotherapy.

Dr. Banfill observed that the COVID-19 diagnosis had been “a reasonable time” before the patients started radiotherapy, and some had been diagnosed with lung cancer as a result of having a chest x-ray for suspected COVID-19.

Of the four patients who were diagnosed during treatment, two had their radiotherapy interrupted as a result.

The low COVID-19 rate is perhaps a result of the protective measures recommended in the United Kingdom, such as advising patients to shield from others, Dr. Banfill said.
 

Are changes to practice likely to hold?

“Part of the reason we actually stopped the data collection in October was that people were starting to go, ‘Well, is this actually a change?’ because they’d been doing it for 6 months,” Dr. Banfill observed during the discussion session.

“It was becoming almost normal for some of these hypofractionated changes. I think there is potential for these to become more embedded going forward,” she said. Data on how these changes might affect patients in the long term is going to be the focus of a future analysis.

“There is ongoing data collection on recurrence and survival and toxicity, which will hopefully provide more information on the outcomes of this patient group,” Dr. Banfill said.

The COVID-RT Lung project is supported by the NIHR Manchester Biomedical Research Centre. Dr. Banfill and Dr. Lievens reported no relevant conflicts of interest.

An increase in the use of hypofractionated radiotherapy for lung cancer has been one of the many consequences of the COVID-19 pandemic, according to initial data from the COVID-RT Lung study.

The U.K.-based study showed that patients with stage I-III lung cancer who were set to undergo radiotherapy with curative intent were more likely to receive fewer fractions at higher doses when treated between April and October 2020. During that period, 19% of patients had their radiotherapy dose or fractionation schedule changed to deviate from standard care.

In addition, 8% of patients who were set to undergo surgery ultimately received radiotherapy instead, presumably to ease pressures on already struggling intensive care services, said Kathryn Banfill, MBChB, of Christie NHS Foundation Trust in Manchester, England.

Dr. Banfill presented results from the COVID-RT Lung study at the European Lung Cancer Virtual Congress 2021 (Abstract 203MO).


 

New guidelines prompt study

When the COVID-19 pandemic began, European and joint European and North American guidelines were issued to try to ensure that lung cancer patients would continue to receive the best possible treatment under the circumstances. This included guidance on how and when to use treatments such as radiotherapy.

One U.K. guideline included recommendations on the use of hypofractionation in the COVID-19 era. The recommendations focused on altering the dosage or length of radiotherapy treatments to try to reduce the number of hospital visits, thereby reducing the risk of exposing patients to SARS-CoV-2.

“The aim of these guidelines is very much to reduce the risk to patients,” Dr. Banfill said. “These patients are often at higher risk of serious COVID-19, both as a result of their cancer and also as a result of many of the coexisting medical conditions that they have, such as COPD [chronic obstructive pulmonary disease],” she explained.

It is often assumed that cognitive decline is an inevitable part of aging, but a new study of centenarians suggests otherwise.

Investigators found that despite the presence of neuropathologies associated with Alzheimer’s disease (AD), many centenarians maintained high levels of cognitive performance.

“Cognitive decline is not inevitable,” senior author Henne Holstege, PhD, assistant professor, Amsterdam Alzheimer Center and Clinical Genetics, Amsterdam University Medical Center, said in an interview.

“At 100 years or older, high levels of cognitive performance can be maintained for several years, even when individuals are exposed to risk factors associated with cognitive decline,” she said.

The study was published online Jan. 15 in JAMA Network Open.
 

Escaping cognitive decline

Dr. Holstege said her interest in researching aging and cognitive health was inspired by the “fascinating” story of Hendrikje van Andel-Schipper, who died at age 115 in 2015 “completely cognitively healthy.” Her mother, who died at age 100, also was cognitively intact at the end of her life.

“I wanted to know how it is possible that some people can completely escape all aspects of cognitive decline while reaching extreme ages,” Dr. Holstege said.

To discover the secret to cognitive health in the oldest old, Dr. Holstege initiated the 100-Plus Study, which involved a cohort of healthy centenarians.

The investigators conducted extensive neuropsychological testing and collected blood and fecal samples to examine “the myriad factors that influence physical health, including genetics, neuropathology, blood markers, and the gut microbiome, to explore the molecular and neuropsychologic constellations associated with the escape from cognitive decline.”

The goal of the research was to investigate “to what extent centenarians were able to maintain their cognitive health after study inclusion, and to what extent this was associated with genetic, physical, or neuropathological features,” she said.

The study included 330 centenarians who completed one or more neuropsychological assessments. Neuropathologic studies were available for 44 participants.

To assess baseline cognitive performance, the researchers administered a wide array of neurocognitive tests, as well as the Mini–Mental State Examination, from which mean z scores for cognitive domains were calculated.

Additional factors in the analysis included sex, age, APOE status, cognitive reserve, physical health, and whether participants lived independently.

At autopsy, amyloid-beta (A-beta) level, the level of intracellular accumulation of phosphorylated tau protein in neurofibrillary tangles (NFTs), and the neuritic plaque (NP) load were assessed.
 

Resilience and cognitive reserve

At baseline, the median age of the centenarians (n = 330, 72.4% women) was 100.5 years (interquartile range, 100.2-101.7). A little over half (56.7%) lived independently, and the majority had good vision (65%) and hearing (56.4%). Most (78.8%) were able to walk independently, and 37.9% had achieved the highest International Standard Classification of Education level of postsecondary education.

The researchers found “varying degrees of neuropathology” in the brains of the 44 donors, including A-beta, NFT, and NPs.

The duration of follow-up in analyzing cognitive trajectories ranged from 0 to 4 years (median, 1.6 years).

Assessments of all cognitive domains showed no decline, with the exception of a “slight” decrement in memory function (beta −.10 SD per year; 95% confidence interval, –.14 to –.05 SD; P < .001).

Cognitive performance was associated with factors of physical health or cognitive reserve, for example, greater independence in performing activities of daily living, as assessed by the Barthel index (beta .37 SD per year; 95% CI, .24-.49; P < .001), or higher educational level (beta .41 SD per year; 95% CI, .29-.53; P < .001).

Despite findings of neuropathologic “hallmarks” of AD post mortem in the brains of the centenarians, these were not associated with cognitive performance or rate of decline.

APOE epsilon-4 or an APOE epsilon-3 alleles also were not significantly associated with cognitive performance or decline, suggesting that the “effects of APOE alleles are exerted before the age of 100 years,” the authors noted.

“Our findings suggest that after reaching age 100 years, cognitive performance remains relatively stable during ensuing years. Therefore, these centenarians might be resilient or resistant against different risk factors of cognitive decline,” the authors wrote. They also speculate that resilience may be attributable to greater cognitive reserve.

“Our preliminary data indicate that approximately 60% of the chance to reach 100 years old is heritable. Therefore, to get a better understanding of which genetic factors associate with the prolonged maintenance of cognitive health, we are looking into which genetic variants occur more commonly in centenarians compared to younger individuals,” said Dr. Holstege.

“Of course, more research needs to be performed to get a better understanding of how such genetic elements might sustain brain health,” she added.
 

A ‘landmark study’

Commenting on the study in an interview, Thomas Perls, MD, MPH, professor of medicine, Boston University, called it a “landmark” study in research on exceptional longevity in humans.

Dr. Perls, the author of an accompanying editorial, noted that “one cannot absolutely assume a certain level or disability or risk for disease just because a person has achieved extreme age – in fact, if anything, their ability to achieve much older ages likely indicates that they have resistance or resilience to aging-related problems.”

Understanding the mechanism of the resilience could lead to treatment or prevention of AD, said Dr. Perls, who was not involved in the research.

“People have to be careful about ageist myths and attitudes and not have the ageist idea that the older you get, the sicker you get, because many individuals disprove that,” he cautioned.

The study was supported by Stichting Alzheimer Nederland and Stichting Vumc Fonds. Research from the Alzheimer Center Amsterdam is part of the neurodegeneration research program of Amsterdam Neuroscience. Dr. Holstege and Dr. Perls reported having no relevant financial relationships. The other authors’ disclosures are listed on the original article.

Nonalcoholic fatty liver disease (NAFLD) in children is almost always caused by excess body weight, not other etiologies, based on a retrospective analysis of 900 patients.

Just 2% of children with overweight or obesity and suspected NAFLD had other causes of liver disease, and none tested positive for autoimmune hepatitis (AIH), reported lead author Toshifumi Yodoshi, MD, PhD, of Cincinnati Children’s Hospital Medical Center, and colleagues.

“Currently, recommended testing of patients with suspected NAFLD includes ruling out the following conditions: AIH, Wilson disease, hemochromatosis, alpha-1 antitrypsin [A1AT] deficiency, viral hepatitis, celiac disease, and thyroid dysfunction,” the investigators wrote in Pediatrics.

Yet evidence supporting this particular battery of tests is scant; just one previous pediatric study has estimated the prevalence of other liver diseases among children with suspected NAFLD. The study showed that the second-most common etiology, after NAFLD, was AIH, at a rate of 4%.

But “the generalizability of these findings is uncertain,” noted Dr. Yodoshi and colleagues, as the study was conducted at one tertiary center in the western United States, among a population that was predominantly Hispanic.

This uncertainty spurred the present study, which was conducted at two pediatric centers: Cincinnati Children’s Hospital Medical Center (2009-2017) and Yale New Haven (Conn.) Children’s Hospital (2012-2017).

The final analysis involved 900 patients aged 18 years or younger with suspected NAFLD based on hepatic steatosis detected via imaging and/or elevated serum aminotransferases. Demographically, a slight majority of the patients were boys (63%), and approximately one-quarter (26%) were Hispanic. Median BMI z score was 2.45, with three out of four patients (76%) exhibiting severe obesity. Out of 900 patients, 358 (40%) underwent liver biopsy, among whom 46% had confirmed nonalcoholic steatohepatitis.

All patients underwent testing to exclude the aforementioned conditions using various diagnostics, revealing that just 2% of the population had etiologies other than NAFLD. Specifically, 11 children had thyroid dysfunction (1.2%), 3 had celiac disease (0.4%), 3 had A1AT deficiency (0.4%), 1 had hemophagocytic lymphohistiocytosis, and 1 had Hodgkin’s lymphoma. None of the children had Wilson disease, hepatitis B or C, or AIH.

Dr. Yodoshi and colleagues highlighted the latter finding, noting that 13% of the patients had autoantibodies for AIH, but “none met composite criteria.” This contrasts with the previous study from 2013, which found an AIH rate of 4%.

“Nonetheless,” the investigators went on, “NAFLD remains a diagnosis of exclusion, and key conditions that require specific treatments must be ruled out in the workup of patients with suspected NAFLD. In the future, the cost-effectiveness of this approach will need to be investigated.”

Interpreting the findings, Francis E. Rushton, MD, of Beaufort (S.C.) Memorial Hospital emphasized the implications for preventive and interventional health care.

“This study showing an absence of etiologies other than obesity in overweight children with NAFLD provides further impetus for pediatricians to work on both preventive and treatment regimens for weight issues,” Dr. Rushton said. “Linking community-based initiatives focused on adequate nutritional support with pediatric clinical support services is critical in solving issues related to overweight in children. Tracking BMI over time and developing healthy habit goals for patients are key parts of clinical interventions.” 

The study was funded by the National Institutes of Health. The investigators reported no conflicts of interest.

Out of 900 patients, 358 (40%) underwent liver biopsy, among whom 46% had confirmed nonalcoholic steatohepatitis.

All patients underwent testing to exclude the aforementioned conditions using various diagnostics, revealing that just 2% of the population had etiologies other than NAFLD. Specifically, 11 children had thyroid dysfunction (1.2%), 3 had celiac disease (0.4%), 3 had A1AT deficiency (0.4%), 1 had hemophagocytic lymphohistiocytosis, and 1 had Hodgkin’s lymphoma. None of the children had Wilson disease, hepatitis B or C, or AIH.

Dr. Yodoshi and colleagues highlighted the latter finding, noting that 13% of the patients had autoantibodies for AIH, but “none met composite criteria.” This contrasts with the previous study from 2013, which found an AIH rate of 4%.

“Nonetheless,” the investigators went on, “NAFLD remains a diagnosis of exclusion, and key conditions that require specific treatments must be ruled out in the workup of patients with suspected NAFLD. In the future, the cost-effectiveness of this approach will need to be investigated.”

Interpreting the findings, Francis E. Rushton, MD, of Beaufort (S.C.) Memorial Hospital emphasized the implications for preventive and interventional health care.

“This study showing an absence of etiologies other than obesity in overweight children with NAFLD provides further impetus for pediatricians to work on both preventive and treatment regimens for weight issues,” Dr. Rushton said. “Linking community-based initiatives focused on adequate nutritional support with pediatric clinical support services is critical in solving issues related to overweight in children. Tracking BMI over time and developing healthy habit goals for patients are key parts of clinical interventions.” 

The study was funded by the National Institutes of Health. The investigators reported no conflicts of interest.

Nonalcoholic fatty liver disease (NAFLD) in children is almost always caused by excess body weight, not other etiologies, based on a retrospective analysis of 900 patients.

Just 2% of children with overweight or obesity and suspected NAFLD had other causes of liver disease, and none tested positive for autoimmune hepatitis (AIH), reported lead author Toshifumi Yodoshi, MD, PhD, of Cincinnati Children’s Hospital Medical Center, and colleagues.

“Currently, recommended testing of patients with suspected NAFLD includes ruling out the following conditions: AIH, Wilson disease, hemochromatosis, alpha-1 antitrypsin [A1AT] deficiency, viral hepatitis, celiac disease, and thyroid dysfunction,” the investigators wrote in Pediatrics.

Yet evidence supporting this particular battery of tests is scant; just one previous pediatric study has estimated the prevalence of other liver diseases among children with suspected NAFLD. The study showed that the second-most common etiology, after NAFLD, was AIH, at a rate of 4%.

But “the generalizability of these findings is uncertain,” noted Dr. Yodoshi and colleagues, as the study was conducted at one tertiary center in the western United States, among a population that was predominantly Hispanic.

This uncertainty spurred the present study, which was conducted at two pediatric centers: Cincinnati Children’s Hospital Medical Center (2009-2017) and Yale New Haven (Conn.) Children’s Hospital (2012-2017).

The final analysis involved 900 patients aged 18 years or younger with suspected NAFLD based on hepatic steatosis detected via imaging and/or elevated serum aminotransferases. Demographically, a slight majority of the patients were boys (63%), and approximately one-quarter (26%) were Hispanic. Median BMI z score was 2.45, with three out of four patients (76%) exhibiting severe obesity. Out of 900 patients, 358 (40%) underwent liver biopsy, among whom 46% had confirmed nonalcoholic steatohepatitis.

Real-world data for caplacizumab outcomes matched those seen in randomized controlled trials (RCTs) for the treatment of immune-mediated thrombotic thrombocytopenic purpura (iTTP), according to the results of a retrospective study.

Data collected from 2018 to 2020 were assessed for 85 patients (4 of them children) receiving caplacizumab at 22 United Kingdom hospitals, according to a report published online in Blood.

Researchers Tina Dutt, PhD, from the Liverpool (England) University Hospitals NHS Foundation Trust, and her colleagues compared patient characteristics and outcomes in these real-world clinical settings to those of caplacizumab trial endpoint results and to historical outcomes in the precaplacizumab era.

Acquired thrombotic thrombocytopenic purpura is an immune-mediated deficiency of the von Willebrand factor–cleaving protease (ADAMTS13), which allows unrestrained adhesion of von Willebrand factor multimers to platelets, leading to thrombocytopenia, hemolytic anemia, and tissue ischemia.

Standard management of iTTP has focused on the replacement of ADAMTS13 and the removal of autoantibodies using plasma exchange and immunosuppression, an approach which has reduced the mortality of acute TTP from greater than 90% to between 10% and 20%, according to the report.

Caplacizumab is a novel anti–von Willebrand factor immunoglobulin fragment that inhibits this interaction between von Willebrand factor multimers and platelets and is now added to the standard treatment regimen. The drug has been assessed in two pivotal multicenter RCTs that led to European Union and U.S. Food and Drug Administration approval.
 

Benefits and risk

Eighty-four of 85 patients received steroid and rituximab as well as plasma exchange along with caplacizumab treatment. All patients had ADAMTS13 activity at presentation less than 20 IU/dL, with 99% of patients (84/85) having ADAMTS13 activity less than 10 IU/dL, confirming a clinical diagnosis of acute TTP, according to the researchers.

The median time to platelet count normalization (3 days), the median duration of plasma exchange (7 days), and the median hospital stay (12 days) were all comparable with the RCT data, according to the researchers. In addition, the median duration of plasma exchange and time from beginning plasma exchange to platelet count normalization were favorable, compared with historical outcomes (P < .05).

TTP recurred in 5 of the 85 patients, all of whom had persistent ADAMTS13 activity less than 5 IU/dL.

There were 31 adverse events reported in 26 patients, 17 of these (55%) were bleeding episodes, and 5 of 31 (16%) were thrombotic events (2 unrelated to caplacizumab). The overall mortality was 6% (five patients), with no deaths attributed to caplacizumab. In four of the five deaths, caplacizumab was introduced more than 48 hours after plasma exchange initiation (range 3-21 days).

“This real-world evidence from the largest series of TTP patients receiving caplacizumab, outside of the pivotal studies, provides confirmation of the therapeutic benefits of caplacizumab and its inherent bleeding risk,” the researchers concluded.

Dr. Dutt and several of her colleagues reported receiving honoraria from Sanofi for serving on advisory boards, as well as speaker fees from Sanofi and Alexion.

Evidence Summary

Single-dose IV ketamine elicits a short-term response

A meta-analysis of RCTs evaluating a single dose of IV ketamine vs placebo for severe depression found that it increased the chance of a treatment response for up to 1 week afterward. Studies included patients with severe (N = 30), treatment-resistant (N = 40), and psychotic depression (N = 10), based on Diagnostic and Statistical Manual of Mental Disorders–Fifth Edition criteria.¹

The primary outcome was treatment response: either an improvement of > 50% on a standardized depression scale or a Clinical Global Impression–Improvement scale score of 1 or 2 (“very much” and “much” improved, respectively, as assessed by a clinician). Ketamine increased the likelihood of short-term response or improvement at 24 hours (3 RCTs; N = 56; odds ratio [OR] = 11; 95% CI, 2-58); at 72 hours (3 RCTs; N = 56; OR = 13; 95% CI, 2-66); and at 7 days (4 RCTs; N = 88; OR = 2.6; 95% CI, 1.1-6.2).¹ Response rates equaled placebo at 2 weeks. The authors rated the RCTs as low quality.

Another systematic review of single-dose IV ketamine vs placebo for major depression and bipolar disorder included 3 additional small, low-quality RCTs, 2 of which showed short-term response to ketamine. The authors used Hedge’s g statistic to standardize effect size (a score of magnitude 0.2 indicates a small effect; 0.6, moderate; 1.2, large; and 2, very large). One RCT (n = 26) found a very large 1-day response (effect size: –2; 95% CI, –2.8 to –1.3), and 2 RCTs found conflicting responses at 12 days (RCT with N = 18: effect size: –0.2; 95% CI, –0.4 to 0.02 [no significant response] vs RCT with N = 8: effect size: –1.5; 95% CI, –2.5 to –0.5).²

More frequent dosing of IV ketamine improves symptoms

An RCT (N = 67) evaluating twice- or thrice-weekly IV ketamine vs placebo in patients with recurrent depression (with at least 1 treatment failure) found that ketamine significantly improved standardized depression scores and response rates at 15 days. Patients with clinically significant suicidality were excluded.³

Researchers randomized patients to IV ketamine (0.05 mg/kg) twice or thrice weekly or to saline control and used the 60-point Montgomery-Asberg Depression Rating Scale (MADRS). A response was defined as a reduction of the MADRS score by 50%.

A single dose of IV ketamine increased the chance of a treatment response for up to 1 week, compared to placebo.

Both ketamine arms produced greater symptom improvement at 15 days, compared to placebo (twice weekly: −18.4 vs −5.7; P < 0.001; thrice weekly: −17.7 vs −3.1; P < 0.001) in addition to higher response rates (twice weekly: 69% vs 15%; P = .005; number needed to treat [NNT] = 2; and thrice-weekly: 54% vs 6%; P = .004; NNT = 2).³ There was no significant difference between twice- or thrice-weekly dosing. The study was flawed by dropouts (N = 57 at 15 days and N = 25 at 28 days), primarily attributed to ketamine adverse effects, that prevented assessment beyond 2 weeks.

Oral ketamine has a moderate effecton depression

A systematic review included 2 low-quality RCTs evaluating oral ketamine vs placebo as adjunctive treatment with sertraline, and oral ketamine vs diclofenac, and found improvement in patients with moderate depression.⁴ In the first RCT (n = 45), researchers found that oral ketamine (25 mg bid) plus sertraline (25 mg titrated up to 150 mg/d) produced more treatment responses (> 50% reduction on a standardized depression rating scale) than placebo plus sertraline (2 weeks: 85.4% vs 42.5%; P < .001; 6 weeks: 85.4% vs 57.5%; P = .005).⁴

In the second RCT (n = 23), researchers randomized patients with mild-to-moderate depression and comorbid chronic headaches to take oral ketamine (50 mg tid) or oral diclofenac (50 mg tid) and measured effect size on standardized depression scores at 3 weeks (no difference) and 6 weeks (Cohen d effect size = 0.79 [rated as a moderate effect]; P = .017).⁴

Nasal esketamine + oral antidepressants boosts treatment response rates

A meta-analysis with 4 RCTs (N = 708) evaluating intranasal esketamine vs placebo as an adjunct to oral antidepressants for patients with predominantly treatment-resistant major depression found that it boosted response rates by about 40%. Researchers randomized patients to intranasal esketamine (mostly 28-84 mg twice weekly for 28 days) or placebo spray as an adjunct to oral antidepressants (duloxetine, escitalopram, sertraline, venlafaxine).

The primary outcomes were treatment response (≥ 50% reduction in depression scores) or remission (a MADRS score < 12). Adjunctive intranasal esketamine produced greater rates of treatment response compared to placebo at 24 hours (21% vs 7%; relative risk [RR] = 8.4; 95% CI, 1.4 to 21.2; P < .02; NNT = 7) and at 28 days (59% vs 43%; RR = 1.4; 95% CI, 1.2 to 1.60; P < .0001; NNT = 6).⁵ Adjunctive intranasal esketamine also produced greater rates of remission at the end of the study (mostly at 28 days), compared with placebo (41% vs 25%; RR = 1.4; 95% CI, 1.2 to 1.7; P = .0004; NNT = 7).⁵ The authors rated study quality as moderate to high.

Adverse effects are common, may cause Tx discontinuation

Ketamine-produced adverse effects (AEs) included confusion (2 trials; N = 76; OR = 3.7; 95% CI, 1.1-12) and emotional blunting (1 trial; N = 30; OR = 23; 95% CI, 1.1-489).¹

A 2018 systematic review assessed the safety of ketamine in depression after single and repeated dose in 60 studies (N = 899; 20 RCTs, 17 open-label-trials, 20 case series, and 3 retrospective studies). The most common AEs reported were headache (35% of studies), dizziness (33%), dissociation (28%), elevated blood pressure (28%), and blurred vision (23%), with the majority reported to resolve shortly after administration. The most common psychiatric AE was anxiety (15%).⁶ Included studies varied greatly in design and dosage form, and no meta-analysis could be performed.

Nasal esketamine produced more AEs causing discontinuation than did placebo (5.8% vs 1.5%; RR = 3.5; 95% CI, 1.34-8.9; number needed to harm [NNH] = 23), including blurred vision, dizziness, sedation, nausea, and dysphoria.⁵A review (5 RCTs and 1 open-label trial; N = 1708) analyzing the cardiac safety profile of intranasal esketamine adjuvant therapy found that it produced transient and asymptomatic blood pressure elevations (OR = 3.2; 95% CI, 1.9-5.8; NNH = 13).⁷

Recommendations from others

A clinical practice guideline from the US Veterans Administration lists IV ketamine as 1 of the therapeutic options for patients with treatment-resistant depression and suicidal ideation.⁸ However, a Department of Veterans Affairs Panel restricted its use to a pre-approved case-by-case basis.⁸

Editor’s takeaway

Physicians with patients facing the all-too-common problem of treatment-resistant major depression will be wondering if ketamine, either by itself or as an augmentation therapy, can help. Unfortunately, the outcomes we report here are too short term to answer that question, and we must await the results of further studies. Augmentation with intranasal esketamine, at a cost of $370/month, might offer some promise.

The authors used Hedge’s g statistic to standardize effect size (a score of magnitude 0.2 indicates a small effect; 0.6, moderate; 1.2, large; and 2, very large). One RCT (n = 26) found a very large 1-day response (effect size: –2; 95% CI, –2.8 to –1.3), and 2 RCTs found conflicting responses at 12 days (RCT with N = 18: effect size: –0.2; 95% CI, –0.4 to 0.02 [no significant response] vs RCT with N = 8: effect size: –1.5; 95% CI, –2.5 to –0.5).²

More frequent dosing of IV ketamine improves symptoms

An RCT (N = 67) evaluating twice- or thrice-weekly IV ketamine vs placebo in patients with recurrent depression (with at least 1 treatment failure) found that ketamine significantly improved standardized depression scores and response rates at 15 days. Patients with clinically significant suicidality were excluded.³

Researchers randomized patients to IV ketamine (0.05 mg/kg) twice or thrice weekly or to saline control and used the 60-point Montgomery-Asberg Depression Rating Scale (MADRS). A response was defined as a reduction of the MADRS score by 50%.

A single dose of IV ketamine increased the chance of a treatment response for up to 1 week, compared to placebo.

Both ketamine arms produced greater symptom improvement at 15 days, compared to placebo (twice weekly: −18.4 vs −5.7; P < 0.001; thrice weekly: −17.7 vs −3.1; P < 0.001) in addition to higher response rates (twice weekly: 69% vs 15%; P = .005; number needed to treat [NNT] = 2; and thrice-weekly: 54% vs 6%; P = .004; NNT = 2).³ There was no significant difference between twice- or thrice-weekly dosing. The study was flawed by dropouts (N = 57 at 15 days and N = 25 at 28 days), primarily attributed to ketamine adverse effects, that prevented assessment beyond 2 weeks.

Oral ketamine has a moderate effecton depression

A systematic review included 2 low-quality RCTs evaluating oral ketamine vs placebo as adjunctive treatment with sertraline, and oral ketamine vs diclofenac, and found improvement in patients with moderate depression.⁴ In the first RCT (n = 45), researchers found that oral ketamine (25 mg bid) plus sertraline (25 mg titrated up to 150 mg/d) produced more treatment responses (> 50% reduction on a standardized depression rating scale) than placebo plus sertraline (2 weeks: 85.4% vs 42.5%; P < .001; 6 weeks: 85.4% vs 57.5%; P = .005).⁴

In the second RCT (n = 23), researchers randomized patients with mild-to-moderate depression and comorbid chronic headaches to take oral ketamine (50 mg tid) or oral diclofenac (50 mg tid) and measured effect size on standardized depression scores at 3 weeks (no difference) and 6 weeks (Cohen d effect size = 0.79 [rated as a moderate effect]; P = .017).⁴

Nasal esketamine + oral antidepressants boosts treatment response rates

A meta-analysis with 4 RCTs (N = 708) evaluating intranasal esketamine vs placebo as an adjunct to oral antidepressants for patients with predominantly treatment-resistant major depression found that it boosted response rates by about 40%. Researchers randomized patients to intranasal esketamine (mostly 28-84 mg twice weekly for 28 days) or placebo spray as an adjunct to oral antidepressants (duloxetine, escitalopram, sertraline, venlafaxine).

The primary outcomes were treatment response (≥ 50% reduction in depression scores) or remission (a MADRS score < 12). Adjunctive intranasal esketamine produced greater rates of treatment response compared to placebo at 24 hours (21% vs 7%; relative risk [RR] = 8.4; 95% CI, 1.4 to 21.2; P < .02; NNT = 7) and at 28 days (59% vs 43%; RR = 1.4; 95% CI, 1.2 to 1.60; P < .0001; NNT = 6).⁵ Adjunctive intranasal esketamine also produced greater rates of remission at the end of the study (mostly at 28 days), compared with placebo (41% vs 25%; RR = 1.4; 95% CI, 1.2 to 1.7; P = .0004; NNT = 7).⁵ The authors rated study quality as moderate to high.

Adverse effects are common, may cause Tx discontinuation

Ketamine-produced adverse effects (AEs) included confusion (2 trials; N = 76; OR = 3.7; 95% CI, 1.1-12) and emotional blunting (1 trial; N = 30; OR = 23; 95% CI, 1.1-489).¹

A 2018 systematic review assessed the safety of ketamine in depression after single and repeated dose in 60 studies (N = 899; 20 RCTs, 17 open-label-trials, 20 case series, and 3 retrospective studies). The most common AEs reported were headache (35% of studies), dizziness (33%), dissociation (28%), elevated blood pressure (28%), and blurred vision (23%), with the majority reported to resolve shortly after administration. The most common psychiatric AE was anxiety (15%).⁶ Included studies varied greatly in design and dosage form, and no meta-analysis could be performed.

Nasal esketamine produced more AEs causing discontinuation than did placebo (5.8% vs 1.5%; RR = 3.5; 95% CI, 1.34-8.9; number needed to harm [NNH] = 23), including blurred vision, dizziness, sedation, nausea, and dysphoria.⁵A review (5 RCTs and 1 open-label trial; N = 1708) analyzing the cardiac safety profile of intranasal esketamine adjuvant therapy found that it produced transient and asymptomatic blood pressure elevations (OR = 3.2; 95% CI, 1.9-5.8; NNH = 13).⁷

Recommendations from others

A clinical practice guideline from the US Veterans Administration lists IV ketamine as 1 of the therapeutic options for patients with treatment-resistant depression and suicidal ideation.⁸ However, a Department of Veterans Affairs Panel restricted its use to a pre-approved case-by-case basis.⁸

Editor’s takeaway

Physicians with patients facing the all-too-common problem of treatment-resistant major depression will be wondering if ketamine, either by itself or as an augmentation therapy, can help. Unfortunately, the outcomes we report here are too short term to answer that question, and we must await the results of further studies. Augmentation with intranasal esketamine, at a cost of $370/month, might offer some promise.

The list of medical comorbidities associated with high risk for severe COVID-19 now includes moderate to severe asthma, diabetes, and substance use disorders, according to the Centers for Disease Control and Prevention.

The CDC’s latest list consists of 17 conditions or groups of related conditions that may increase patients’ risk of developing severe outcomes of COVID-19, the CDC said on a web page intended for the general public.

On a separate page, the CDC defines severe outcomes “as hospitalization, admission to the intensive care unit, intubation or mechanical ventilation, or death.”

Asthma is included in the newly expanded list with other chronic lung diseases such as chronic obstructive pulmonary disease and cystic fibrosis; the list’s heart disease entry covers coronary artery disease, heart failure, cardiomyopathies, and hypertension, the CDC said.

An endocrinologist in Naples, Fla., faces multiple federal charges after police found homemade explosives and bomb-making supplies, as well as numerous illegal drugs, in his home.

Police were executing a search warrant at the home of Christy Daniel Cugini, MD, 63, on March 30 when they found the items, according to Collier County Sheriff’s Office (CCSO).

“An investigation continues and more charges could be brought,” the sheriff’s office said in a statement. As of April 1, Dr. Cugini was out on bond. His next court appearance is on April 26.

A search of his bedroom turned up marijuana, tramadol, oxycodone, and hydrocodone, the sheriff’s office said. According to nbcmiami.com, police also found 560 grams of marijuana and $20,000 in cash and jewelry in a safe.

“Some of the narcotics were in pill bottles with other people’s names on them. Many of the substances were of trafficking quantities. The search also turned up numerous items of narcotic paraphernalia, including heat seal bags, a vacuum sealer, and a scale,” the CCSO report said.

Charges against Dr. Cugini include narcotics trafficking; possession of marijuana with intent to sell/manufacture/deliver; possession of more than 20 grams of marijuana; possession of a controlled substance; and possession of narcotic paraphernalia, according to the report.

He was also charged with nine counts of making/possessing a destructive device.

The CCSO bomb squad was brought in to investigate the homemade explosive devices and supplies, including potassium nitrate and ammonium nitrate – which can be used as oxidizers – PVC pipe, and flash powders used in fireworks in Dr. Cugini’s house and garage.

Newsweek reported that the bomb squad found six red cylindrical devices about 4 inches long, according to information reported in an affidavit from Collier County Officer Jeffrey Tayar. They may have been intended to be a hand-tossed improvised explosive device, Mr. Tayar wrote.

An officer also found three other devices made up of PVC pipe attached to a small wood square. A rifle round was inserted into the PVC pipe, Mr. Tayar’s report said.

“The device could be placed on the ground in such a manner as to leave the rifle round facing up,” Mr. Tayar reportedly wrote. “If downward pressure were applied on the tip of the round ... the rifle round [would] discharge, launching the projectile portion of the round upward, presumably into the foot of the subject stepping on it.”

NBC News reported that deputies said Dr. Cugini appeared to live only with his young daughter.

He initially agreed to speak with deputies but then invoked his Miranda rights and stopped answering questions, NBC said.

Dr. Cugini’s profile has been removed from the Millennium Physician Group website.

His employer offered this statement via spokesperson Liza Fernandez: “We are shocked at the allegations regarding Dr. Christy Cugini. He has been placed on administrative leave until further notice. Millennium is committed to cooperating with law enforcement and is conducting an internal investigation.”

According to U.S. News & World Report, Dr. Cugini is affiliated with NCH Baker Hospital. He received his medical degree from Ross University School of Medicine, now located in Barbados, and has been practicing for more than 20 years.

Attempts to contact Dr. Cugini were unsuccessful.

Patients with migraine experienced about a 60% reduction in pain intensity and number of headache days per month after exposure to green light therapy, according to results of a small study from the University of Arizona, Tucson.

“This is the first clinical study to evaluate green light exposure as a potential preventive therapy for patients with migraine, “ senior author Mohab M. Ibrahim, MD, PhD, said in a press release. “Now I have another tool in my toolbox to treat one of the most difficult neurologic conditions – migraine.”

“Given the safety, affordability, and efficacy of green light exposure, there is merit to conduct a larger study,” he and coauthors from the university wrote in their paper.

The study included 29 adult patients (average age 52.2 years), 22 with chronic migraine and the rest with episodic migraine who were recruited from the University of Arizona/Banner Medical Center chronic pain clinic. To be included, patients had to meet the International Headache Society diagnostic criteria for chronic or episodic migraine, have an average headache pain intensity of 5 out of 10 or greater on the numeric pain scale (NPS) over the 10 weeks prior to enrolling in the study, and be dissatisfied with their current migraine therapy.

The patients were free to start, continue, or discontinue any other migraine treatments as recommended by their physicians as long as this was reported to the study team.
 

White versus green

The one-way crossover design involved exposure to 10 weeks of white light emitting diodes, for 1-2 hours per day, followed by a 2-week washout period and then 10 weeks’ exposure to green light emitting diodes (GLED) for the same daily duration. The protocol involved use of a light strip emitting an intensity of between 4 and 100 lux measured at approximately 2 m and 1 m from a lux meter.

Patients were instructed to use the light in a dark room, without falling asleep, and to participate in activities that did not require external light sources, such as listening to music, reading books, doing exercises, or engaging in similar activities. The daily minimum exposure of 1 hour, up to a maximum of 2 hours, was to be completed in one sitting.

The primary outcome measure was the number of headache days per month, defined as days with moderate to severe headache pain for at least 4 hours. Secondary outcomes included perceived reduction in duration and intensity of the headache phase of the migraine episodes assessed every 2 weeks with the NPS, improved ability to fall and stay asleep, improved ability to perform work and daily activity, improved quality of life, and reduction of pain medications.

The researchers found that when the patients with chronic migraine and episodic migraine were examined as separate groups, white light exposure did not significantly reduce the number of headache days per month, but when the chronic migraine and episodic migraine groups were combined there was a significant reduction from 18.2 to 16.5 headache days per month.

On the other hand, green light did result in significantly reduced headache days both in the separate (from 7.9 to 2.4 days in the episodic migraine group and 22.3 to 9.4 days in the chronic migraine group) and combined groups (from 18.4 to 7.4 days).

“While some improvement in secondary outcomes was observed with white light emitting diodes, more secondary outcomes with significantly greater magnitude including assessments of quality of life, Short-Form McGill Pain Questionnaire, Headache Impact Test-6, and Five-level version of the EuroQol five-dimensional survey without reported side effects were observed with green light emitting diodes,” the authors reported.

“The use of a nonpharmacological therapy such as green light can be of tremendous help to a variety of patients that either do not want to be on medications or do not respond to them,” coauthor Amol M. Patwardhan, MD, PhD, said in the press release. “The beauty of this approach is the lack of associated side effects. If at all, it appears to improve sleep and other quality of life measures,” said Dr. Patwardhan, associate professor and vice chair of research in the University of Arizona’s department of anesthesiology.
 

Better than white light

Asked to comment on the findings, Alan M. Rapoport, MD, clinical professor of neurology at the University of California, Los Angeles, said research has shown for some time that exposure to green light has beneficial effects in migraine patients. This study, although small, does indicate that green light is more beneficial than is white light and reduces headache days and intensity. “I believe patients would be willing to spend 1-2 hours a day in green light to reduce and improve their migraine with few side effects. A larger randomized trial should be done,” he said.

The study was funded by support from the National Center for Complementary and Integrative Health (to Dr. Ibrahim), the Comprehensive Chronic Pain and Addiction Center–University of Arizona, and the University of Arizona CHiLLI initiative. Dr. Ibrahim and one coauthor have a patent pending through the University of Arizona for use of green light therapy for the management of chronic pain. Dr. Rapoport is a former president of the International Headache Society. He is an editor of Headache and CNS Drugs, and Editor-in-Chief of Neurology Reviews. He reviews for many peer-reviewed journals such as Cephalalgia, Neurology, New England Journal of Medicine, and Headache.
