The 2007 and 2008 shingles and varicella vaccination recommendations may have contributed to the declining herpes zoster hospitalization rates in some groups.

The 2007 and 2008 herpes zoster and varicella vaccination recommendations may have affected the declining herpes zoster hospitalization rates in targeted age groups, according to a study published in Vaccine.

The Centers for Disease Control and Prevention officially endorsed the 2005 recommendation from the Advisory Committee on Immunization Practices for the addition of a second booster dose at age 4 to 6 years in the varicella vaccine schedule, and the herpes zoster single-dose vaccine for people aged ³60 years, in 2007 and 2008, respectively. Currently, there are limited published data on the effect of the 2-dose varicella and single-dose herpes zoster vaccine recommendations on herpes zoster incidence in the United States. Therefore, this study examined trends in herpes zoster hospitalization rates and assessed the effect of both policy recommendations, using hospital discharge data.

Discharge data (2001-2015) were extracted to identify primary and secondary herpes zoster diagnoses from the Nationwide Inpatient Sample, which contains annual discharge data for a 20% sample of US hospitals and is the largest publicly available all-payer inpatient care database in the United States, containing roughly 8 million hospitalizations annually. Herpes zoster-associated hospitalization was defined by a first or second discharge diagnosis, indicated with specific International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), or ICD-10-CM codes. 

Annual total and age-specific herpes zoster hospitalization rates and average length of stay trends were examined. The average annual rates for the pre- and postzoster vaccination policy eras were compared (2001-2005 and 2012-2015, respectively). Researchers noted that the 2006 to 2011 period was treated as a transition period because of a vaccine supply shortage resulting from manufacturing issues. In addition, absolute change in herpes zoster hospitalizations was calculated.

Results suggested that the 2-dose varicella vaccination recommendation may have contributed to declining herpes zoster hospitalization rates among children (£14 years), and the 2008 herpes zoster vaccine may have also contributed to declining hospitalization rates for adults aged ³60 years. From 2001 to 2015, there were 400,651 herpes zoster hospitalizations, which accounted for 0.07% of all US hospitalizations during the study period. 

The number of herpes zoster hospitalizations increased in direct proportion with age: 0.07% in those aged 7 to 14 years, 0.06% in those aged 40 to 49 years, 0.07% in those aged 60 to 69 years, 0.12% in those aged 70 to 79 years, 0.16% among those aged 80+ years, and less than 0.05% in all other groups. In 2001, the annual incidence rate of herpes zoster hospitalizations was 8.6 per 100,000 population in the US and decreased to 6.8 per 100,000 population in 2015. Although there were steady increases in the overall rate of herpes zoster hospitalizations from 2001 to 2008, this significantly decreased between 2001 and 2015. 

Further, the largest decreases in herpes zoster hospitalization rates between 2001 and 2015 occurred in groups that were directly targeted by the 2007/2008 recommendations. The age-adjusted average annual change in hospital rates from pre- vs post-herpes zoster vaccine period was 1.9 fewer hospitalizations per 100,000 population (P <.001).

Overall, the study authors concluded, “The recent licensure of a new 2-dose recombinant sub-unit herpes zoster vaccine and expansion of the recommended age of herpes zoster vaccination to ³50 years should have significant [effect] in the [US] on vaccination coverage and herpes zoster hospitalizations over time, and continued surveillance will be necessary to measure this [effect].”

In an effort to effectively address global health concerns, the WHO has announced the 13th General Programme of Work, a 5-year strategic plan spanning from 2019 to 2023.
In an effort to effectively address global health concerns, the WHO has announced the 13th General Programme of Work, a 5-year strategic plan spanning from 2019 to 2023.

The health of one country is the health of all countries. Diseases can travel around the world in days, along with the people and vectors that carry and transmit them. With environmental issues setting the stage for eruption of disease on a global level, it has become clear that the medical initiatives of 1 small village or town can only work if the world at large supports it.

In an effort to effectively address global health concerns, the World Health Organization (WHO) has announced the 13th General Programme of Work, a 5-year strategic plan spanning from 2019 to 2023 that hopes to ensure that “1 billion more people benefit from access to universal health coverage, 1 billion more people are protected from health emergencies and 1 billion more people enjoy enough better health and well-being.”

At the center of their efforts, the WHO first identified 10 key issues that are projected to threaten public health this year. At the very top of the list are air pollution and climate change, followed by noncommunicable diseases, pandemic influenza, fragile settings, antimicrobial resistance, recurring pathogens, weak primary care, and vaccine hesitancy. Rounding out the list are continued wide-scale risks of acquiring dengue fever and HIV, 2 diseases that can be largely contained.

Threat No. 1: Air Pollution and Climate Change

The WHO estimates that 7 million people die prematurely every year from diseases such as cancer, stroke, heart, and lung disease, of which about 90% of cases are associated with poor air quality. “Household air pollution using dirty cook stoves indoors causes around 4 million premature deaths every year. About 3 billion people cook using polluting open fires or dirty fuels. Almost half the deaths due to pneumonia in children aged less than 5 years are caused by soot inhaled from household air pollution,” explained María P. Neira, MD, director of the Department of Public Health, Environment, and Social Determinants of Health at the WHO.

Mortality is expected to increase by 250,000 deaths annually between 2030 and 2050 from climate-related malnutrition, malaria, diarrhea, and heat stress. “Awareness of the health effects of pollution and climate change is increasing, and there is much more evidence now that air pollution is responsible for many health issues, ranging from brain development in babies, to heart disease and stroke in adults,” Dr Neira added. The WHO is calling on countries to commit to reaching new designated air quality guideline levels by 2030.

Threat No. 2: Noncommunicable Diseases

Diabetes, cancer, and heart disease collectively cause 41 million deaths worldwide, accounting for more than 70% of global mortality. An estimated 15 million people between the ages of 30 and 60 years die prematurely, the vast majority of those from low- and middle-income countries. The WHO set goals to significantly reduce the 5 major risk factors for all these diseases by 2030, including tobacco use, physical inactivity, overuse of alcohol, poor diet, and air pollution.

Threat No. 3: Pandemic Flu

A pandemic is expected to happen again; the only questions are when and where it will start.

At this time, 153 institutions across 114 countries participate in the WHO’s Global Influenza Surveillance and Response System to monitor and track influenza infections around the world, the data from which are then used to prepare vaccines for the next influenza season. The biggest challenge is the potential for a new strain to develop, particularly in underdeveloped nations that cannot adequately prepare and respond to prevent an epidemic from spreading through global portals.

Threat No. 4: People in Fragile or Vulnerable Settings

Approximately 22% of the world’s population, or 1.6 billion people, live in areas where they are frequently displaced from their homes by war, famine, or climate disasters. One serious consequence for these displaced populations is the loss of access to basic healthcare services, which puts large populations at risk for outbreaks of disease that can then spread worldwide. The WHO has focused on providing continuity of quality care to those in fragile settings, including immunization services.

Threat No. 5: Antimicrobial resistance

The WHO predicts that the era of treating infections such as salmonella, pneumonia, tuberculosis, or gonorrhea with antimicrobial drugs is nearly done, with no other treatments set to replace them. The WHO’s global action plan focuses on increasing awareness, using preventive measures to reduce risks for infection, and careful antimicrobial stewardship among the medical community.

Threat No. 6: Recurring High-Threat Pathogens

There are a number of known diseases that could cause public health emergencies. Pathogens from Ebola to Zika, Nipah to Middle East respiratory syndrome coronavirus and Severe Acute Respiratory Syndrome, among others, are all listed on the international watch list for priority research called the WHO’s R&D Blueprint. These diseases have no effective treatments or vaccines, and can readily spread not only in rural areas but also within densely populated urban zones, particularly during active conflicts that limit access to care. In addition, the WHO continues to focus its efforts on Disease X, the unknown pathogen that can cause a global outbreak at any time.

Threat No. 7: Weak Primary Healthcare

Many countries, particularly those with fewer national resources, fail to provide adequate basic medical care for their populations, creating windows for opportunistic diseases to go unchecked and spread. An estimated half of the world’s population does not have access to care for even the most essential and basic needs. The WHO has committed to partnering with countries to help strengthen primary care globally in accordance with the Astana Declaration.

Threat No. 8: Vaccine Hesitancy

The 2019 WHO initiative states that vaccine hesitancy “threatens to reverse progress made in tackling vaccine-preventable diseases.” An estimated 2 to 3 million deaths annually are prevented by vaccination, which could be further extended to prevent another 1.5 million deaths through improved global vaccine coverage. 

One of the target diseases is measles, which has been a recurring issue in countries that were once close to eliminating the disease, including the United States. Globally, there has been a 30% increase in measles cases. “The resurgence of measles is of serious concern, with extended outbreaks occurring across regions, and particularly in countries that had achieved, or were close to achieving, measles elimination,” said Soumya Swaminathan, MD, deputy director general for programmes at WHO. “Without urgent efforts to increase vaccination coverage and identify populations with unacceptable levels of under- or unimmunized children, we risk losing decades of progress in protecting children and communities against this devastating, but entirely preventable, disease,” she added.

Threat No. 9: Dengue Fever

An estimated 40% of the world is now at risk of dengue fever as climate change increases the infectious season in primary areas such as Bangladesh and India while increasing the range of the disease to more temperate countries such as Nepal. Approximately 390 million additional infections are diagnosed per year. The WHO’s Dengue control strategy aims to reduce deaths by 50% by 2020. 

Threat No. 10: HIV

Despite tremendous advances in treatment, HIV continues to spread among those who have little or no access to effective treatments. WHO Regional Director for Africa Matshidiso Moeti, MBBS, initiated a call to action on January 18 to end HIV among children in West and Central Africa. “Diagnosis and treatment of children living with HIV is a major challenge. It is unacceptable that only 1 in 4 children living with HIV have access to treatment,” she said. “Most of the children with HIV are receiving suboptimal treatment regimens. This is a particular concern in the [subregions] where drug resistance rates are reaching over 60% in some areas, with only 30% of people on treatment successfully achieving viral suppression.”

Alarmingly, new populations at risk are also being identified. Young girls and women aged 15 to 24 years in sub-Saharan Africa now account for 1 in 4 HIV infections in that region, despite being only 10% of the population. “This is part of the reason why I made adolescent health a priority in the African Region,” Dr Moeti added.

FDA: New Plan for Regulations, Oversight of Dietary Supplement Industry

The FDA has announced a new plan to significantly modernize the regulation and oversight of dietary supplements.
The FDA has announced a new plan to significantly modernize the regulation and oversight of dietary supplements.

The Food and Drug Administration (FDA) has announced a new plan to significantly modernize the regulation and oversight of dietary supplements, according to a statement released today. The new document will be the first update in over 25 years.

“I’ve personally benefited from the use of dietary supplements and, as a physician, recognize the benefits of certain supplements as a part of a comprehensive care plan,” said FDA Commissioner Scott Gottlieb, MD, in the statement. 

“It’s clear that the US Food and Drug Administration plays an important role in helping consumers make use of safe, high-quality dietary supplements while also protecting Americans from the potential dangers of products that don’t meet the agency’s standards for marketing.”

Continue Reading Below

The dietary supplement industry is worth more than $40 billion; more than 50,000 supplement products are available to consumers. In contrast, when the original Dietary Supplement Health and Education Act (DSHEA) was passed, the industry was worth only $4 billion.

While DSHEA stipulates a number of requirements for the manufacture and label of dietary supplements, there are numerous loopholes through which so-called bad actors can “exploit the halo created by quality work of legitimate manufactures to…distribute and sell dangerous products that put consumers at risk.”

Dr Gottlieb added that one of the top goals of the new regulation is to ensure that consumers still have access to safe, well-manufactured, appropriately labeled products, while holding accountable those who do not comply with the laws.

“Legitimate industry benefits from a framework that inspires the confidence of consumers and providers. Patients benefit from products that meet high standards for quality,” Dr Gottlieb concluded.

Data collection included socio-demographic variables, comorbidities, treatment-related clinical events, immunosuppressant usage, concomitant treatment, and more.
Data collection included socio-demographic variables, comorbidities, treatment-related clinical events, immunosuppressant usage, concomitant treatment, and more.

Patients with moderate to severe atopic dermatitis using immunosuppressant treatment experience unsatisfactory outcomes, frequently need systemic steroid rescue therapy, and report many associated adverse events, according to a study published in PLoS One.

Researchers in this retrospective cohort study used data from the Truven Health MarketScan database to analyze the impact immunosuppressant treatment has on patients with atopic dermatitis. All patients included in this study had a pre-index baseline period that lasted 6 months and a post-index follow-up period that lasted 12 months. All patients were categorized into either the immunosuppressant arm that included treatments of cyclosporine, azathioprine, methotrexate, and mycophenolate mofetil or a control arm that excluded treatments of systemic immunosuppressants, systemic corticosteroids, or phototherapy. Data collection included socio-demographic variables, comorbidities, treatment-related clinical events, immunosuppressant usage, concomitant treatment, and adjustments in dose or type of immunosuppressant.

Continue Reading Below

The study included 4204 patients using an immunosuppressant to treat atopic dermatitis who were matched with 4201 controls using another form of treatment. During the post-index follow-up period for patients in the immunosuppressant arm, 68.5% were non-persistent, 84.6% received concomitant treatment, 36.3% required dose escalation, 7.6% required additional immunosuppressants, and 2.8% switched immunosuppressants. Significantly more patients in the immunosuppressant arm had immunosuppressant-related clinical events, required hospitalization (<.0001), required immunosuppressant-related monitoring tests (<.001), and had higher levels of healthcare resource utilization and associated costs.

Limitations of this study include using medical claim codes as a basis for diagnosis, which could lead to misclassification of patients. Also, using retrospective data means a direct causal relationship cannot be proven.

The researchers concluded that their study “highlights the unmet need for more effective long-term therapies for atopic dermatitis with improved safety profiles and reduced monitoring requirements.”

These findings indicate age-specific treatment approaches would likely benefit patients with atopic dermatitis.
These findings indicate age-specific treatment approaches would likely benefit patients with atopic dermatitis.

Age-specific treatment modalities may be more beneficial for patients with atopic dermatitis (AD) across the life span, according to research that explored changes in the molecular profiles of people with moderate to severe AD. The findings were published in the Journal of Allergy and Clinical Immunology.

Researchers examined age-specific changes in blood and lesional/non-lesional tissues from patients with moderate to severe AD (n=246) and age-matched, healthy controls (n=72) via Singulex, quantitative reverse transcription-polymerase chain reaction, and immunohistochemistry. Participants were categorized into 18-40, 41-60, and 61+ age groups for analysis.

Although disease severity, as measured by SCORing Atopic Dermatitis (SCORAD), was similar across the age groups with AD (mean: ∼60; P =.873), dendritic cell infiltrates (CD1b+, FcεRI+; P <.05) decreased with age. Measures of TH2 (IL-5, IL-13, CCL13, CCL18, CCL26) decreased significantly with age in participants with AD, but increased with age in controls. TH22-secreted IL-22 also decreased with age in participants with AD only (P <.05), while TH1- (IFN-γ, IL-12/23p40, STAT1, CXCL9; P <.05 for CXCL9) and TH17-related markers (IL-17A, IL-20; P <.05 for IL-20) increased with age in both controls and patients with AD.

Significant increases in terminal differentiation measures were observed in older participants with AD (LOR, FLG; P <.05), while decreases were observed in hyperplasia markers (epidermal thickness, K16, Ki67; P <.05 for K16) and S100As (S100A8; P <.01). Serum trends among participants with AD mimicked skin findings, with age-related TH2 downregulation (CCL26; r=-0.32, P <.1) and TH1 upregulation (IFN-γ; r=0.48, P <.01).

Study investigators concluded that these findings indicate age-specific treatment approaches would likely benefit patients with AD. “Therapeutic targeting with TH2-, TH22-, and TH17/TH1-specific antagonists are needed in order to understand the varying pathogenic roles of these axes in [atopic dermatitis]. Elucidating the differential patterns of immune skewing and barrier abnormalities among different [atopic dermatitis] phenotypes may be useful for developing personalized treatment approaches, especially in patients with recalcitrant [atopic dermatitis].”

Omadacycline is noninferior to moxifloxacin for community-acquired bacterial pneumonia and noninferior to linezolid for acute bacterial skin infections.

HealthDay News — Omadacycline is noninferior to moxifloxacin for community-acquired bacterial pneumonia and noninferior to linezolid for acute bacterial skin infections, according to two studies published in the Feb. 7 issue of the New England Journal of Medicine.

Roman Stets, M.D., Ph.D., from the City Clinical Hospital in Zaporizhzhia, Ukraine, and colleagues randomly assigned adults with community-acquired bacterial pneumonia to receive omadacycline (386 patients) or moxifloxacin (388 patients), with a total treatment duration of seven to 14 days. The researchers found that omadacycline was noninferior to moxifloxacin for early clinical response (81.1 and 82.7 percent, respectively; difference, −1.6 percentage points; 95 percent confidence interval, −7.1 to 3.8). Omadacycline was also noninferior for the posttreatment evaluation rates of investigator-assessed clinical response (87.6 and 85.1 percent, respectively; difference, 2.5 percentage points; 95 percent confidence interval, −2.4 to 7.4).

William O’Riordan, M.D., from eStudySite in San Diego, and colleagues randomly assigned adults with acute bacterial skin and skin-structure infections to omadacycline (316 patients) or linezolid (311 patients), with total treatment duration of seven to 14 days. The researchers found that omadacycline was noninferior to linezolid in the modified intention-to-treat analysis with respect to early clinical response (84.8 and 85.5 percent, respectively; difference, −0.7 percentage points; 95 percent confidence interval, −6.3 to 4.9). With respect to investigator-assessed clinical response at the posttreatment evaluation, omadacycline was also noninferior to linezolid (86.1 and 83.6 percent, respectively; difference, 2.5 percentage points; 95 percent confidence interval, −3.2 to 8.2).

“Well designed clinical trials of omadacycline for the treatment of infections caused by multiple-drug-resistant gram-negative pathogens are needed to determine its real value as an antibacterial agent,” write the authors of an accompanying editorial.

Both studies were funded by Paratek, the manufacturer of omadacycline.

Evidence Lacking for Persistence and Effectiveness of Systemic Psoriasis Therapies

Share this content:
This systematic review was limited by literature that was lacking in survival analyses and inconsistent definitions of drug discontinuation across the literature.
This systematic review was limited by literature that was lacking in survival analyses and inconsistent definitions of drug discontinuation across the literature.

A systematic review of the persistence and effectiveness of systemic therapies for psoriasis was limited by lack of evidence and incomplete reporting in clinical practice, according to research published in the British Journal of Dermatology.

Researchers utilized a literature search using Embase, MEDLINE, PubMed, and the Cochrane Library to identify studies that investigated persistence of therapy survival probabilities, mean or median time to therapy discontinuation, or the proportion of patients discontinuing treatment with acitretin, ciclosporin, fumaric acid esters (FAE), or methotrexate. The observational studies reporting on persistence (therapy duration or the proportion of patients discontinuing therapy during follow-up) or effectiveness (improvements in Psoriasis Area and Severity Index [PASI] or Physician Global Assessment [PGA]) were published between January 1, 2007, and November 1, 2017. Eight studies involving patients with moderate to severe psoriasis (N=4624) were included for analysis.

Continue Reading Below

The probability of drug survival at 1 year was 23% for ciclosporin, 42% for acitretin, and 50% for methotrexate. Discontinuations due to adverse events were more common for FAE than for methotrexate (42-46% FAE vs 22% methotrexate). For discontinuations due to ineffectiveness, results were mixed (44% acitretin, 21% ciclosporin, and 33% methotrexate vs 22% FAE).

This systematic review was limited by literature that was lacking in survival analyses and inconsistent definitions of drug discontinuation across the literature.

Further research is needed to fully elucidate the persistence and effectiveness of acitretin, ciclosporin, FAE, and methotrexate; reviews should include a more robust definition to minimize risk of excluding studies that used different but relevant outcome definitions.

Strong Bidirectional Association Found Between Depression and Alopecia

Share this content:
Primary study outcomes were the development of alopecia areata in the cohort exposed to depression and the development of major depressive disorder in the cohort exposed to alopecia.
Primary study outcomes were the development of alopecia areata in the cohort exposed to depression and the development of major depressive disorder in the cohort exposed to alopecia.

Major depressive disorder and alopecia areata have a strong bidirectional association, according to a study published in JAMA Dermatology.

The investigators of this population-based retrospective study sought to assess the bidirectional relationship of major depressive disorder and alopecia areata by establishing clinical temporality between these diseases.

The study investigators extracted data on approximately 12 million patients, aged 10 to 90 years, from a registry of general practices in the United Kingdom between January 1986 to May 2012. Risk for alopecia areata was assessed in a cohort of patients with incident major depressive disorder (n=405,339) and in a reference general population cohort (n=5,738,596). Risk for major depressive disorder was assessed in a cohort of patients with incident alopecia areata (n=6861) and in a reference general population cohort (n=6,137,342).

Continue Reading Below

Primary study outcomes were the development of alopecia areata in the cohort exposed to depression and the development of major depressive disorder in the cohort exposed to alopecia.

Analyzing for risk of alopecia areata, 662 patients (0.2%) in the major depressive disorder cohort developed alopecia vs 6356 patients (0.1%) in the reference cohort. After adjusting for variables, a diagnosis of major depressive disorder was associated with increased risk of subsequently developing alopecia areata by 90% (hazard ratio [HR] 1.90; 95% CI, 1.67-2.15; P <.001). Demonstrated by lower incident ratios in both cohorts, antidepressant use showed a protective effect on the risk for alopecia areata (HR 0.57; 95% CI, 0.53-0.62; P <.001). Analyzing for risk of major depressive disorder, 513 patients (7.5%) in the alopecia areata cohort developed depression vs 405,102 patients (6.6%) in the reference cohort. After adjusting for variables, incident alopecia areata was associated with the risk of subsequently developing major depressive disorder by 34% (HR 1.34; 95% CI, 1.23-1.46; P <.001).

Limitations to study included the possible misclassification of major depressive disorder or alopecia areata and potential confounding factors not considered in the study.

Through reciprocal analysis of major depressive disorder and alopecia areata, the investigators discovered a bidirectional association between the 2 diseases in which the incidence of major depression imposed a significant risk for the subsequent development of alopecia areata. Additional evidence of these findings was supported by the association of antidepressant use with reduced alopecia risk compared with not taking antidepressants.

After 16 weeks of treatment with dupilumab, the median SCORAD score decreased 55%.
After 16 weeks of treatment with dupilumab, the median SCORAD score decreased 55%.

After 16 weeks of dupilumab usage, patients with atopic dermatitis saw improvements in quality of life, pruritus, and sleep, according to a study published in The British Journal of Dermatology.

Researchers of this prospective, observational study evaluated the efficacy of dupilumab on atopic comorbidities, symptoms, and immunoglobulin E levels in a real-life practice setting. Patients with moderate to severe atopic dermatitis completed ophthalmologic and ear nose and throat examinations, respiratory tests, SCOring Atopic Dermatitis (SCORAD) evaluations, visual analogue scales for sleep and pruritus, Investigator’s Global Assessment, Dermatology Life Quality Index, and immunoglobulin E concentration laboratory work.

Of the 19 patients included, 79% were men, and the mean age was 38 years old. Follow-up data were available for 18 patients. At baseline, 10 patients had >2 atopic comorbidities, including asthma, allergic rhinitis, allergic conjunctivitis, or food allergy. All but 1 patient had above normal immunoglobulin E levels; 10 patients had abnormal ophthalmologic evaluations; and 15 patients had seasonal rhinitis, perennial rhinitis, or rhinosinusitis. The median SCORAD was 49, the median visual analogue scale for pruritus was 5, and the median visual analogue for sleep loss was 3.

After 16 weeks of treatment with dupilumab, the median SCORAD score decreased 55% (P <.001), the median visual analogue scale for pruritus decreased significantly, the median visual analogue for sleep loss decreased significantly, and there was a significant decrease in median total immunoglobulin E levels (P =.001). Ophthalmologic examinations showed a worsening of conjunctivitis in 5 of the 10 patients. Ear nose and throat examinations indicated 10 patients showed stability and 4 showed improvements, and no significant changes were found in asthma control.

Limitations of this study included small sample size, short-term follow-ups, and the observational nature of the study.

In conclusion, “[d]upilumab reduces global severity, pruritus, sleep loss and improves quality of life in [atopic dermatitis] in real-life clinical practice.”

The HIDRAdisk, a validated, visual, interactive electronic instrument completed together by patients and dermatologists, is an easy-to-use quality of life tool that could improve the management of hidradenitis suppurativa while also strengthening patient-clinician relationships, according to a study published in Journal of the European Academy of Dermatology and Venerology.

The chronic relapsing inflammatory skin disease hidradenitis suppurativa has a significant negative impact on patient quality of life, which has been reported to be greater than that of atopic eczema and psoriasis. This multicenter, longitudinal, observational study was designed to demonstrate the reliability, responsiveness, and overall validity of HIDRAdisk, a new tool designed to rapidly assess hidradenitis suppurativa burden with an intuitive graphic visual of the measurement outcome. Study authors compared HIDRAdisk with the following validated questionnaires: Work Productivity and Activity Impairment-General Health (WPAI:GH), Dermatology Life Quality Index (DLQI), and Skindex-16. They evaluated HIDRAdisk’s correlation with disease severity as measured by Hurley stage and Hidradenitis Suppurativa Physician Global Assessment (HS-PGA).

Participants were identified from 27 Italian dermatologic centers (N=140; mean age 34.9±11.0 years, 59% women). HIDRAdisk showed a statistically significant correlation with both Hurley stage (P =.0002) and HS-PGA (P =.0041), a good correlation with WPAI:GH (correlation coefficient: 0.5947), and a strong correlation with Skindex-16 (correlation coefficient: 0.7568) and DLQI (correlation coefficient: 0.6651). Very good internal consistency was demonstrated, with raw and standardized Cronbach coefficient values greater than >0.80 (0.894 and 0.898, respectively), correlation between the 10 items ranging between 0.308 and 0.673, good test-retest reliability (Spearman correlation coefficient, 0.8331; P <0.0001), and statistically significant responsiveness to changes.

Study investigators concluded that “the HIDRAdisk is a validated visual instrument administered on electronic devices, completed by patient and dermatologist together, making it an easy-to-use [quality of life] tool that, in our wishes, should be implemented soon in routine clinical practice to improve the management of [hidradenitis suppurativa], as well as strengthen the patient–physician relationship.”
