BACKGROUND: Patient-Reported Outcomes Measurement Information System Global Health (PGH) was validated to assess health-related quality of life in several diseases. Little is known about its measurement properties in adult atopic dermatitis. OBJECTIVE: Examine the measurement properties of PGH in adult atopic dermatitis. METHODS: A prospective dermatology practice-based study of 994 atopic dermatitis patients (18-97 years). RESULTS: PGH physical and mental health 4-item and abridged 2-item T scores, as well as mapped EuroQol-5D score, showed strong to very strong correlation with one another and moderate to strong Spearman correlations with Patient-Oriented Scoring Atopic Dermatitis, Patient-Health Questionnaire-9, Patient-Reported Outcomes Measurement Information System sleep disturbance and related impairment, Eczema Area and Severity Index, objective Scoring Atopic Dermatitis; and weak to moderate correlations with Patient Oriented Eczema Measure, numeric rating scale worst itch and average itch, and Scoring Atopic Dermatitis. The Dermatology Life Quality Index (DLQI) had stronger correlations with Patient Oriented Eczema Measure, Patient-Oriented Scoring Atopic Dermatitis, numeric rating scale worst itch and average itch, Eczema Area and Severity Index, and Scoring Atopic Dermatitis, but weaker correlations with Patient-Health Questionnaire-9 and Patient-Reported Outcomes Measurement Information System sleep disturbance and related impairment (convergent/divergent validity). PGH and DLQI scores had similarly poor ability to differentiate between levels of self-reported global atopic dermatitis severity (known-groups validity). No floor or ceiling effects were observed. No PGH or DLQI items had differential item functioning by demographics. PGH and DLQI scores showed fair to good responsiveness. Finally, PGH and DLQI showed similarly good test-retest reliability. LIMITATIONS: Single-center study. CONCLUSION: PGH scores had sufficient validity and reliability to assess health-related quality of life in atopic dermatitis.

BACKGROUND: It is well established that asthma is common in patients with atopic dermatitis (AD). OBJECTIVES: We performed a systematic review and meta-analysis to determine the prevalence of asthma and respiratory symptoms in individuals with AD as well as the association between AD and asthma. METHODS: At least 2 authors independently searched the medical databases PubMed, EMBASE, LILACS, and SCOPUS for all English-language studies with data on asthma prevalence among patients with AD or the association between AD and asthma. Pooled odds ratios with 95% confidence intervals (CIs) and pooled proportions were estimated with random-effects models. The Newcastle-Ottawa scale was used to assess study quality. RESULTS: The search yielded 39,503 articles. Of these, 213 studies were included in a quantitative analysis. The overall pooled prevalence of asthma was 25.7% (95% CI, 23.7-27.7) in patients with AD and 8.1% (95% CI, 7.0-9.4) among reference individuals. There was a significant association between AD and asthma when compared with reference individuals (odds ratio, 3.03; 95% CI, 2.64-3.47). LIMITATIONS: The definitions of AD and asthma differed across the included studies and varied from self-report to physician diagnosed. CONCLUSIONS: Asthma is a common comorbidity of AD. Physicians should be cognizant of this relationship and address asthma symptoms in their patients.

BACKGROUND: Few outcome measures were validated for assessing depressive symptoms in AD. Patient Health Questionnaire-9 (PHQ9) and the abridged PHQ2 are established patient-reported outcome measures of depressive symptoms. OBJECTIVE: We sought to examine the measurement properties of PHQ9 and PHQ2 in adult AD. A prospective dermatology-practice based study of 458 AD patients (age 18-97 years) was conducted. RESULTS: PHQ9 strongly correlated with Dermatology Life Quality Index, Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep-Disturbance and Sleep-Related Impairment, and PROMIS Itch Questionnaire Mood and Sleep (PIQ-MS), and moderately correlated with Patient-Oriented Eczema Measure, Numeric Rating Scale (NRS) average-itch, NRS-sleep, Eczema Area and Severity Index, Scoring AD and Rajka-Langeland scores. PHQ2 had significantly weaker correlations than PHQ9 with PROMIS SD, SRI and PIQ-MS, but similar correlations with other outcomes. PHQ9 and PHQ2 had good discriminant validity. Changes from baseline in PHQ9 and PHQ2 were poorly or weakly correlated with changes of the other outcome measures. There was no differential item functioning of PHQ items. PHQ9 showed good reliability (intraclass correlation coefficient range: 0.80-0.87). PHQ2 had slightly lower reliability (0.76-0.82). CONCLUSIONS: PHQ9 and PHQ2 had similar measurement properties, but PHQ2 was more feasible to assess depressive symptoms in AD.

Prurigo nodularis (PN) is a chronic, pruritic, debilitating disease. Previous studies found that chronic pruritus in general negatively affects patients' quality of life (QoL). However, results about the impact of PN on QoL are conflicting. Our objective was to assess the QoL burden of PN. A systematic review was conducted of all published studies that assessed QoL measures in PN. OVID MEDLINE, EMBASE, SCOPUS, and Web of Science were searched. Pooled meta-analysis (means) was performed using random-effects weighting. Overall, 13 studies met inclusion criteria. All studies identified QoL reductions in patients suffering from PN compared to control groups. The most common QoL instrument used was the Dermatology Life Quality Index [n = 9 studies; pooled mean (95% confidence interval): 13.8 (10.6-16.9), denoting a very large effect]. In particular, PN was associated with substantial impact on multiple domains of QoL. No publication bias was detected. In conclusion, QoL is negatively impacted in PN. Future studies are necessary to determine the best instruments of measuring QoL in PN patients, better understand this association, and assess the impact in males and females separately.

BACKGROUND: The ideal patient-reported outcome measure to assess sleep disturbance in atopic dermatitis (AD) has not been determined. OBJECTIVE: We sought to determine the measurement properties of the Patient-Reported Outcomes Measurement Information System (PROMIS) Itch Questionnaire Mood and Sleep (PIQ-MS), Sleep Disturbance (SD), Sleep-Related Impairment (SRI), and Epworth Sleepiness Scale (ESS) in adults with AD. METHODS: A prospective dermatology practice-based study was performed using questionnaires and evaluation by a dermatologist (n=611). RESULTS: PIQ-MS, PROMIS SD, SRI, and ESS had good convergent validity with intensity and frequency of sleep disturbance, Patient-Oriented Eczema Measure, Eczema Area and Severity Index, total and objective-Scoring AD, Numerical Rating Scale of worst-itch and average-itch, and Dermatology Life Quality Index. PIQ-MS had significantly better correlations with other severity measures than the other sleep measures (Fisher z-scores, P≤0.007). PIQ-MS, and to lesser extent PROMIS SD, PROMIS SRI and ESS had good discriminant validity. All four sleep assessments showed fair responsiveness to change of severity of sleep-disturbance, AD and itch. PIQ-MS had the best reliability. PIQ-MS, PROMIS SD, SRI and ESS showed good internal consistency and were feasible for use in clinical practice. CONCLUSIONS: PIQ-MS, followed by PROMIS SD, had the best construct validity and reliability in adult AD.

BACKGROUND: Atopic dermatitis (AD) is associated with heterogeneous triggers of itch, which may affect AD course and severity. OBJECTIVE: To characterize the triggers of itch in adult AD. METHODS: This was a prospective dermatology practice-based study using questionnaires and evaluation by a dermatologist (n = 587). Thirteen itch triggers were assessed using the patient-reported outcomes measurement information system Itch-Triggers. RESULTS: Overall, 381 (64.9%) patients reported greater than or equal to 1 itch trigger in the past week and 212 (36.1%) reported greater than or equal to 3 itch triggers. The most commonly reported triggers were stress (35.4%), sweat (30.5%), weather change (24.7%), dry air (24.4%), and heat (24.0%). In multivariable Poisson regression models, the number of itch triggers was associated with more severe patient-reported global AD severity, Numeric Rating Scale worst itch, Patient-Oriented Eczema Measure, Scoring Atopic Dermatitis sleep, Numeric Rating Scale skin pain, Eczema Area and Severity Index, and objective Scoring Atopic Dermatitis. The seasonality of AD was associated with distinct itch triggers. In multivariable logistic regression models, the number of itch triggers was associated with less than or equal to 3 months of AD remission during the year, greater than or equal to 2 AD flares, and AD being worse during some seasons. Four patterns of itch triggers were identified using latent class analysis, each associated with different clinical characteristics. CONCLUSION: Itch triggers are common and affect the course of AD. Itch triggers are an important end point to assess in patients with AD.

BACKGROUND: Atopic dermatitis (AD) is associated with itch, pain, and sleep disturbance, all of which may contribute toward cognitive dysfunction. OBJECTIVE: To determine the relationship of AD severity and cognitive function in adults. METHODS: We performed a prospective dermatology practice-based study using questionnaires and evaluation by a dermatologist (n = 386). Cognitive function was assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) Cognitive Function 8-item Short-Form. RESULTS: At baseline, 118 patients (58.1%) reported ≥1 symptoms of cognitive dysfunction in the past 4 weeks, with 29 (14.3%) having mild, 11 (5.4%) moderate, and 4 (2.0%) severe PROMIS Cognitive Function T-scores. In propensity score-weighted regression models, PROMIS Cognitive Function T-scores were inversely associated with patient-reported global AD severity, Patient Oriented Eczema Measure (POEM), Numeric Rating Scale worst itch and skin pain, SCORing Atopic Dermatitis (SCORAD)-sleep, POEM-sleep, Eczema Area and Severity Index, and SCORAD, with stepwise decreases of cognitive function with worsening AD severity. At all AD severity levels, cognitive dysfunction was associated with increased Dermatology Life Quality Index and ItchyQoL scores. Changes from baseline in PROMIS Cognitive Function T-scores were weakly to moderately inversely correlated with changes from baseline in multiple AD outcomes. LIMITATIONS: Single-center study without non-AD controls. CONCLUSION: Cognitive dysfunction is associated with AD severity. Cognitive function may be an important end point for monitoring treatment response in AD.

BACKGROUND: The American Contact Dermatitis Society Contact Allergen Management Program (CAMP) database was developed to provide patients with safe alternative products free of selected contact allergens. However, the CAMP database also records valuable information including the frequency of contact allergen searches for patients. OBJECTIVES: The aim of the study was to determine the relative prevalence of contact allergens in North America. METHODS: Data from the CAMP database were analyzed from January 1, 2018, to January 1, 2019. The number of searches performed for each specific allergen served as a measure of the relative prevalence for each contact allergen. Results were then stratified by age, sex, atopic history, and patch screening tray used. RESULTS: The 2018 CAMP data show that many of the prevalent allergens are not currently on any contact allergy screening series. These data strongly indicate that testing only to an 80-item screening series will not provide adequate care for many patients with contact allergy. The most prevalent contact allergens seen were fragrance mix, nickel, balsam of Peru, methylchloroisothiazolinone/methylisothiazolinone, and cobalt. Some important differences are seen when stratifying CAMP data by age, sex, atopic history, and patch screening tray used. LIMITATIONS: Possible sources of data error exist because of lack of uniformity of patch test practices. CONCLUSIONS: The CAMP database can be used to determine the relative prevalence of contact allergens, to help develop North American core screening patch test series, and to document the medical necessity of more comprehensive patch testing for patients with recalcitrant contact allergy.

BACKGROUND: Little is known about the measurement properties of Patient-Oriented Scoring Atopic Dermatitis (PO-SCORAD) in adults with atopic dermatitis (AD). Even less is known about how PO-SCORAD performs compared with the Patient-Oriented Eczema Measure (POEM). OBJECTIVE: To examine the measurement properties of PO-SCORAD and compare them with those of POEM. METHODS: A prospective dermatology practice-based study of 291 patients with AD (age range, 18-72 years). RESULTS: PO-SCORAD and POEM were moderately correlated with each other (Spearman ρ = 0.56) and had weak-moderate correlations with the Numeric Rating Scale (NRS) worst itch and average itch, Dermatology Life Quality Index (DLQI), ItchyQOL, Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance (SD) and Sleep-Related Impairment (SRI), Patient Health Questionnaire-9 (PHQ-9), and Eczema Area and Severity Index (EASI) (P < .001). POEM had significantly stronger correlations with DLQI, ItchyQOL, and EASI than did PO-SCORAD. PO-SCORAD and POEM had fair discriminant validity. Changes from baseline in PO-SCORAD and POEM were moderately correlated with each other; were weakly to strongly correlated with NRS worst itch and average itch, DLQI, ItchyQOL, PROMIS SD, PROMIS SRI, PHQ-9, and EASI; and had good test-retest reliability. There was no differential item functioning of items or floor or ceiling effects for PO-SCORAD or POEM. The thresholds for meaningful change for PO-SCORAD and POEM were -15.5 and -5.0, respectively. Median completion times for PO-SCORAD and POEM were 3 minutes and 1 minute, respectively. CONCLUSION: PO-SCORAD and POEM had good construct and cross-cultural validity, reliability, and responsiveness in adults with AD and were feasible for use in clinical trials and practice. However, POEM had better measurement properties than PO-SCORAD.

Prurigo nodularis (PN) and lichen simplex chronicus (LSC) are debilitating chronic pruritic diseases that can lead to and be exacerbated by psychosocial distress. However, little is known about the mental health (MH) comorbidities of PN/LSC. We sought to evaluate the likelihood and cost-burden of MH comorbidities and emergencies associated with PN/LSC. Data were examined from the 2002-2012 Nationwide Inpatient Sample, including a representative ~ 20% sample of US hospitalizations (n = 87,053,155 admissions). Inpatients with vs. without PN/LSC had higher odds of MH disorders overall (39.4% vs. 20.0%; adjusted odds ratio [95% confidence interval, CI] 2.26 [2.13-2.41]) and in all 15 individual MH disorders examined. Inpatients with vs. without PN/LSC were more likely to be admitted with a primary diagnosis of a MH disorder (4.5% vs. 2.2%; 2.16 [1.91-2.45]), particularly developmental, psychotic, and mood disorders, history of MH disorders or substance abuse, and cognitive disorders. PN/LSC were associated with prolonged inpatient length of stay, and an excess $0.69 million in inpatient costs of care indirectly related to hospitalization for MH disorders. In conclusion, inpatients with PN/LSC had increased likelihood of comorbid MH disorders and emergencies requiring hospitalization. Optimized approaches are needed for screening and managing MH comorbidities in PN/LSC.

BACKGROUND: It is known that malignant melanoma (MM) survivors are at increased risk of future primary MM. However, the risk for noncutaneous second primary malignancies (SPMs) is not as well-understood. METHODS: An observational study utilizing data from the Surveillance, Epidemiology, and End Results (SEER) database was performed, assessing data from patients diagnosed with primary cutaneous MM to measure overall, as well as specific, tumor type and risk of SPM. RESULTS: Of the 132,438 patients recruited in the study population (mean age 55.5 years; 54% male), 23,794 SPMs were observed (O) (18% of patients at a mean age of 68.8 years), while 17,923 SPMs were expected (E) to occur (O : E 1.33, 95% CI 1.31-1.34). Excluding cutaneous MM occurring as a new primary malignancy, there was a significantly increased risk for SPMs among cutaneous MM survivors for each of the following tumor types: eye and orbit melanoma, tracheal, thyroid, salivary gland, retroperitoneum, small intestine, kidney, lymphoid and hematopoietic system, lymphoma overall, non-Hodgkin lymphoma, lymphocytic leukemia overall, chronic lymphocytic leukemia, male genital system (including prostate), and breast. Certain gender-specific trends for SPMs were also detected. CONCLUSIONS: Patients with primary cutaneous MM are at increased risk for primary noncutaneous MM as well as noncutaneous SPMs that include numerous tumor types. Enhanced oncologic surveillance for a variety of tumor types in melanoma survivors is warranted.

BACKGROUND: Alopecia areata (AA) is a common autoimmune alopecia with heterogeneous severity and distribution. Previous studies found conflicting results about AA epidemiology. OBJECTIVE: To determine the prevalence, incidence, and predictors of AA, alopecia totalis, alopecia ophiasis, and alopecia universalis. METHODS: A systematic review of all published cohort and cross-sectional studies that analyzed AA and its subtypes. MEDLINE, Embase, LILACS, Scopus, Cochrane Library, and GREAT were searched. At least 2 reviewers performed study title/abstract review and data extraction. Random-effects meta-analysis was used because of significant heterogeneity (I2 = 99.97%). RESULTS: Ninety-four studies met the inclusion criteria. The pooled prevalence (95% confidence interval, N) of AA overall was 2.11% (1.82-2.42, N = 302,157,365), with differences of population-based (0.75% [0.49-1.06%], N = 301,173,403) and clinic-based (3.47% [3.01-3.96], N = 983,962) studies. The prevalences of alopecia totalis, ophiasis, and universalis were 0.08% (0.04-0.13, N = 1,088,149), 0.02% (0.00-0.06, N = 1,075,203), and 0.03% (0.01-0.06, N = 1,085,444), respectively. AA prevalence (95% confidence interval) increased over time (<2000: 1.02% [0.85-1.22]; 2000-2009: 1.76% [1.51-2.03]; >2009: 3.22% [2.59-3.92]; P < .0001) and differed by region. AA prevalence was significantly lower in adults (1.47% [1.18-1.80]) than children (1.92% [1.31-2.65]; P < .0001). CONCLUSIONS: AA affects 2% of the global population. AA prevalence is lower in adults than children, is increasing over time, and significantly differs by region.

BACKGROUND: Atopic dermatitis (AD) has a variable disease course and intermittent triggers, and responses to topical therapy vary, potentially affecting the magnitude of the placebo response in AD trials. OBJECTIVE: To determine the predictors of increased placebo response in randomized controlled trials of AD. METHODS: We performed a systematic review and meta-analysis of randomized controlled trials for systemic therapy in AD published during 2007-2018. We searched the Cochrane Library, Medline, Embase, Global Resource for EczemA Trials (GREAT), Literature of the Latin American and Caribbean Health Sciences (LILACS), and Scopus. Two authors performed study selection and data extraction. Multivariable mixed models were constructed for Cohen D of Eczema Area and Severity Index (EASI), SCORing Atopic Dermatitis (SCORAD), numeric rating scale (NRS)-itch and visual analog scale (VAS)-itch, and Dermatology Life Quality Index (DLQI). RESULTS: Overall, 64 trials were included. Use of concomitant topical therapy prescriptions, study duration ≥3 months, and fewer treatment arms were associated with an increased placebo response for EASI, NRS- and VAS-itch, and DLQI. For EASI, the placebo response was increased in studies with a higher proportion of male patients, mild-moderate mean baseline EASI scores, and no blinding. For NRS-itch, and VRS-itch, higher placebo responses were associated with higher proportions of male patients and moderate-severe mean itch scores at baseline. CONCLUSION: Placebo responses can be reduced in clinical trials of systemic therapy in AD by incorporating double- and triple-blinding, balancing the sex distribution of patients, disallowing concomitant use of prescription topical therapy, and having shorter study durations.

BACKGROUND: Gray matter (GM) atrophy in brain is one of the best predictors of long-term disability in multiple sclerosis (MS), and recent findings have revealed that localized GM atrophy is associated with clinical disabilities. GM atrophy associated with each disability mapped to a distinct brain region, revealing a disability-specific atlas (DSA) of GM loss. OBJECTIVE: To uncover the mechanisms underlying the development of localized GM atrophy. METHODS: We used voxel-based morphometry (VBM) to evaluate localized GM atrophy and Clear Lipid-exchanged Acrylamide-hybridized Rigid Imaging-compatible Tissue-hYdrogel (CLARITY) to evaluate specific pathologies in mice with experimental autoimmune encephalomyelitis (EAE). RESULTS: We observed extensive GM atrophy throughout the cerebral cortex, with additional foci in the thalamus and caudoputamen, in mice with EAE compared to normal controls. Next, we generated pathology-specific atlases (PSAs), voxelwise mappings of the correlation between specific pathologies and localized GM atrophy. Interestingly, axonal damage (end-bulbs and ovoids) in the spinal cord strongly correlated with GM atrophy in the sensorimotor cortex of the brain. CONCLUSION: The combination of VBM with CLARITY in EAE can localize GM atrophy in brain that is associated with a specific pathology in spinal cord, revealing a PSA of GM loss.

BACKGROUND: Previous studies found conflicting results about whether hidradenitis suppurativa (HS) is associated with depression or anxiety. OBJECTIVES: To determine the relationship of HS with depression and anxiety. METHODS: A systematic review was performed of published observational studies in MEDLINE, PubMed, Embase, Global Resource for Eczema Trials (GREAT), Latin American and Caribbean Health Sciences Literature (LILACS), Cochrane, Scopus, and PsychInfo that analyzed depression or anxiety in HS. Two reviewers performed title/abstract review and data extraction. Meta-analysis was performed with random-effects weighting. RESULTS: Thirty-eight studies met inclusion criteria; 27 had sufficient data for meta-analysis. The prevalences of depression (26.5% vs 6.6%) and anxiety (18.1% vs 7.1%) were higher in persons with versus without HS. Patients with HS had higher odds of depression in 12 of 13 studies and pooled analysis (odds ratio, 2.54; 95% confidence interval, 2.15-3.01), and anxiety in 6 of 6 studies and pooled analysis (odds ratio, 2.00; 95% confidence interval, 1.66-2.42). Similar results were found in sensitivity analyses for different methods of HS diagnosis (physician diagnosed and chart review) and control groups (healthy and dermatologic control individuals). HS was associated with higher antidepressant and anxiolytic use and with suicidality, but not mean depression and anxiety scale scores. LIMITATIONS: Individual-level data were unavailable. CONCLUSIONS: Patients with HS have higher odds of depression, anxiety, and suicidality.

BACKGROUND: The optimal approaches for monitoring sleep disturbances in adults with atopic dermatitis (AD) is not established. Multiple patient-reported outcome measures for AD and itch have sleep-related items. These items have not been validated previously. OBJECTIVE: Assess the measurement properties of sleep-related items from the Patient-Oriented Eczema Measure (POEM), SCORing AD (SCORAD), 5-dimensions of itch (5D), and ItchyQOL in adults with AD. METHODS: We performed a prospective dermatology practice-based study using questionnaires and evaluation by a dermatologist (n = 115). RESULTS: There was modest overlap and weak-moderate concordance of responses to the different assessments. Regarding concurrent validity, POEM-sleep, SCORAD-sleep, 5D-sleep, and ItchyQOL-sleep showed moderate correlations with each other. Regarding convergent validity, all items showed moderate correlation with total POEM, but weak correlations with Eczema Area and Severity Index (EASI), objective and total SCORAD, moderate to strong correlations with mean ItchyQOL and Dermatology Life Quality Index (DLQI), but poor or no significant correlation with Numeric Rating Scale (NRS) for worst or average itch. Regarding discriminant validity, all items showed significant and stepwise increases with increasing self-reported and physician-reported AD severity (Kruskal-Wallis, P < .01 for all). Floor effects were observed for POEM-sleep (n = 53, 46.1%), SCORAD-sleep (n = 28, 24.4%), 5D-sleep (n = 41, 35.7%), and ItchyQOL-sleep (n = 33, 28.7%); no ceiling effects were observed. Change in sleep-related item scores showed moderate strong correlations with change in POEM, 5Ditch, mean ItchyQOL, DLQI, objective and total SCORAD, and EASI, but inconsistent correlations with change of itch severity. CONCLUSION: Sleep-related items from POEM, SCORAD, 5D and ItchyQOL showed good validity and responsiveness to monitor sleep disturbances in adult AD patients.

BACKGROUND: Psoriasis is associated with psychosocial distress. Little is known about the relationship between psoriasis and mental health (MH) emergencies. OBJECTIVE: To examine the associations of psoriasis and MH hospitalizations in the USA. METHODS: Data from the 2002-2012 National Inpatient Sample were analyzed, including an approximately 20% sample of all US hospitalizations (n = 87,053,155 children and adults). RESULTS: Hospitalization for MH disorders occurred more commonly in those with psoriasis compared to those without psoriasis (4.04 vs. 2.21%). In multivariable logistic regression models, psoriasis was associated with higher odds of admission for any MH disorder overall (adjusted odds ratio [95% confidence interval]: 2.32 [2.24-2.41]), as well as 9 of the 15 MH-specific disorders examined. Associated MH disorders included: anxiety, schizophrenia, personality disorder, depression, substance use disorders, history of MH disorder, alcohol-related disorders, adjustment disorders, and cognitive disorders. Children with versus those without psoriasis were also more likely to have a primary hospitalization for any MH disorder (2.82 [2.24-3.56]). Psoriasis inpatients were also more likely to have a primary hospitalization for any MH disorder compared to those with alopecia areata (1.99 [1.45-2.74]) or hidradenitis suppurativa (3.97 [3.49-4.52]). Psoriasis patients hospitalized with any MH disorder had higher mean [95% confidence interval] cost of inpatient care (USD 11,004 [10,846-11,241] vs. 9,547 [8,730-10,364]; p < 0.0001) compared to those without psoriasis, with USD 1,610,860 excess costs annually, with the majority of the costs coming from depression and mood disorders. CONCLUSIONS: Children and adults with psoriasis had increased hospitalization for multiple MH disorders, which were associated with a considerable financial burden.

OBJECTIVE: To evaluate alterations in apparent axon diameter and axon density obtained by high-gradient diffusion MRI in the corpus callosum of MS patients and the relationship of these advanced diffusion MRI metrics to neurologic disability and cognitive impairment in MS. METHODS: Thirty people with MS (23 relapsing-remitting MS [RRMS], 7 progressive MS [PMS]) and 23 healthy controls were scanned on a human 3-tesla (3T) MRI scanner equipped with 300 mT/m maximum gradient strength using a comprehensive multishell diffusion MRI protocol. Data were fitted to a three-compartment geometric model of white matter to estimate apparent axon diameter and axon density in the midline corpus callosum. Neurologic disability and cognitive function were measured using the Expanded Disability Status Scale (EDSS), Multiple Sclerosis Functional Composite (MSFC), and Minimal Assessment of Cognitive Function in MS battery. RESULTS: Apparent axon diameter was significantly larger and axon density reduced in the normal-appearing corpus callosum (NACC) of MS patients compared to healthy controls, with similar trends seen in PMS compared to RRMS. Larger apparent axon diameter in the NACC of MS patients correlated with greater disability as measured by the EDSS (r = 0.555, P = 0.007) and poorer performance on the Symbol Digits Modalities Test (r = -0.593, P = 0.008) and Brief Visuospatial Memory Test-Revised (r = -0.632, P < 0.01), tests of interhemispheric processing speed and new learning and memory, respectively. INTERPRETATION: Apparent axon diameter in the corpus callosum obtained from high-gradient diffusion MRI is a potential imaging biomarker that may be used to understand the development and progression of cognitive impairment in MS.
