Associated comorbidities in psoriasis and inflammatory bowel disease.

BACKGROUND: The association between psoriasis and inflammatory bowel disease (IBD) has been previously reported although a great deal remains unknown about associated comorbidities. OBJECTIVES: The aim of this study was to examine comorbidities in individuals diagnosed with both psoriasis and IBD, and to compare those with individuals diagnosed with psoriasis-only. We also looked at differences within the IBD group by clearly defining that cohort. METHODS: We included 146 patients diagnosed with both psoriasis and IBD and 146 controls diagnosed of psoriasis-only without previous records of IBD, matched by gender, ethnicity and age (±5 years). Patients were obtained from the research patient data repository of Brigham and Women's Hospital (BWH) and Massachusetts General Hospital. Controls were obtained from the psoriatic arthritis and psoriasis follow-up study (PAFS) at BWH. The comparison between the two groups included socio-demographics, comorbidities and laboratory inflammation parameters. RESULTS: Compared to individuals with psoriasis-only, patients with both psoriasis and IBD had significantly higher rates of autoimmune thyroiditis (2.1% vs. 6.8%), hepatitis (0.7 vs. 6.2%) and diabetes (11.0% vs. 26.7%). In addition, of the 146 patients with psoriasis and IBD, 60 (41.1%) were diagnosed with seronegative arthritis. The average C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) of the last visits in our clinics were significantly elevated compared to the individuals with psoriasis-only (ESR, 33.5 vs. 4.0 mm/h; CRP, 9.1 vs. 2.3 mg/L; both P-values <0.0001). CONCLUSIONS: We found that patients with both, psoriasis and IBD have a number of further associated comorbidities, some at significantly higher levels than individuals with psoriasis-only. Common inflammatory pathways and genetic predispositions for specific patterns in the immune response may play an important role in the evolution of associated conditions.

Development and pilot-testing of a psoriasis screening tool.

BACKGROUND: There is a need to validate psoriasis self-reports in epidemiological studies, where individuals may not be seeing dermatologists or other health care providers. OBJECTIVES: To develop and pilot test the Psoriasis Screening Tool (PST) in an ambulatory setting. PATIENTS AND METHODS: The PST was designed with eight closed-ended questions requiring a 'yes' or 'no' response. Typical images of skin, nail and scalp changes in psoriasis were included with respective questions. We administered the PST to 222 consecutive individuals being seen at a dermatology clinic. All English-speaking subjects completed the PST without assistance. A board-certified dermatologist established the diagnosis of psoriasis or excluded psoriasis in all participants. RESULTS: A total of 222 completed PST questionnaires were included for analysis. There were 111 individuals in the psoriasis group and 111 individuals in the nonpsoriasis group. A combination of three questions resulted in a sensitivity of 96.4% [95% confidence interval (CI) 93.2-98.0] and specificity of 97.3% (95% CI 94.1-98.9) for psoriasis. Adding a pictorial question increased the sensitivity of the screening tool to 98.2% (95% CI 95.0-99.5). Of the 111 individuals with psoriasis, 69% answered yes to having plaque-type psoriasis, 50% answered yes to having nail involvement, 66% answered yes to having scalp involvement, and 59% answered yes to having inverse-type psoriasis. CONCLUSIONS: This pilot study suggests that the PST can distinguish individuals with psoriasis from individuals without psoriasis in an English-speaking population being seen at an outpatient dermatology clinic. Furthermore, the PST may be used to identify psoriasis phenotypes. Although the PST may be limited by spectrum bias in this pilot study, we believe it remains a reliable tool to collect information on psoriasis in remote populations.

The impact of spirometry on pediatric asthma diagnosis and treatment.

Research has shown that spirometry is underutilized in the clinical setting. This study profiles the use of spirometry in an asthma management program at an inner-city community health clinic. Eligible subjects included 56 children who presented with an acute asthma exacerbation. Physicians recorded patient diagnosis before and after viewing spirometry. Bivariate and multivariate analysis was used to determine associations between symptoms and forced expiratory volume in 1 second (FEV1). Physicians changed 30.4% of patients' treatment plans after viewing spirometry results. Wheezing was significantly associated with FEV1 in bivariate analysis; however, multivariate modeling failed to identify significant relationships. The use of spirometry influenced patient diagnosis and treatment.
