Factors Influencing Willingness to Pay for Teledermatology among Patients with Psoriasis

Objective: To determine the proportion of patients with psoriasis prepared to pay for TD. Attitudes and factors influencing their willingness to pay (WTP) were evaluated. Materials and Methods: This cross-sectional study was conducted from July 2020 to October 2021. Adult patients with psoriasis completed a 2-page self-administered questionnaire. Results: Of 200 patients, 133 (66.5%) were unfamiliar with TD. However, 144 (72%) were prepared to pay for TD if it were introduced. The majority of patients answered that 300 Bath was the maximum price that they were willing to pay for TD service. Compared with traditional in-person visits, the significant positive influencing factors on WTP were TD’s quicker delivery of treatment, lower costs, and non-inferiority to usual care. Multivariate analysis showed that the independent factors for WTP were higher educational levels, elimination of out-of-pocket, in-hospital visit expenses, owning a business, TD options suited to psoriasis, and no adverse effects on the patient-doctor relationship. Conclusion: Knowing patients’ attitudes toward TD and the factors influencing their WTP is essential for developing efficient services. Data from this study can be used to develop successful TD services for patients with psoriasis

Utility of the Siriraj Psoriatic Arthritis Screening Tool, the Thai Psoriasis Epidemiology Screening Tool, and the Early Arthritis for Psoriatic Patients Questionnaire to Screen for Psoriatic Arthritis in an Outpatient Dermatology Clinic Setting, and Identification of Factors Significantly Associated with Psoriatic Arthritis

Objective: To assess the clinical utility of the Psoriasis Epidemiology Screening Tool (PEST), the Early Arthritis for Psoriatic Patients (EARP) questionnaire, and the Siriraj Psoriatic Arthritis Screening Tool (SiPAT) as screening tools for psoriatic arthritis (PsA), and to identify factors significantly associated with PsA. Methods: This cross-sectional study included adult psoriasis patients who attended the outpatient clinic at Siriraj Hospital and had not been diagnosed with PsA during 1 March 2017 to 28 February 2018. Participants completed the EARP, PEST, and SiPAT, after which musculoskeletal history was taken, and examination and radiography were performed. Diagnosis of PsA was based on Classification Criteria for Psoriatic Arthritis. Receiver operator characteristic (ROC) curves, sensitivity, and specificity were used to determine assessment tool performance. Logistic regression analysis was used to identify factors associated with PsA. Results: Eighty-seven patients with a mean age of 45.90±14.75 years were enrolled. Twenty-six (29.88%) patients were diagnosed as PsA. According to ROC values, EARP had the best discriminative power (0.83) for distinguishing between psoriatic patients with and without PsA (SiPAT: 0.78, PEST: 0.77). SiPAT had the highest sensitivity (92.3%), followed by EARP (84.6%) and PEST (50.0%); whereas, PEST had the highest specificity (82.0%), followed by EARP (62.3%) and SiPAT (54.1%) for detecting PsA. Multivariate analysis revealed body surface area involvement >10% to be the only independent predictor of PsA (OR: 2.99, 95% CI: 1.09-8.21). Conclusion: SiPAT is an effective and simple to use tool for screening PsA in psoriasis patients. Body surface area involvement >10% is a significant predictor of PsA

Evaluating Risk Factors for Cumulative Life Course Impairment in Psoriasis using Patient-Acceptable Symptom State and European Quality of Life 5 Dimensions (EQ-5D)

Objective: To evaluated the health-utility values and risk factors for cumulative life course impairment (CLCI) using Patient Acceptable Symptom State (PASS) and European Quality of Life 5 Dimensions (EQ-5D). Materials and Methods: This cross-sectional investigation enrolled patients with psoriasis. Patients were asked PASS questions about their overall self-perceived health state, adaptation, and expectations for current, future, and lifelong conditions. The patients also completed EQ-5D. Results: The mean age of 139 enrolled patients was 45.8 ± 14.4 years, and 57.6% were women. Most cases had chronic plaque psoriasis 121 (87.1%). For current PASS, satisfaction was significantly associated with older age, being married, and lower disease severity. The mean health-utility value and visual analog scale of the 139 patients were 0.89 ± 0.12 and 77.0 ± 17.4, respectively. Patients would not accept their disease if they had moderate to extreme problems in usual activities and depression/anxiety for the future and lifelong. Univariate analysis revealed that depression and usual activities were significantly associated with satisfaction for current PASS, future PASS, and lifelong PASS. Conclusion: Disease severity, age, marital status, problems with usual activities, and depression/anxiety were significantly related to CLCI. These findings may allow physicians to identify psychosocial and psychological aspects of psoriatic patients at high risk for developing CLCI. Early and adequate treatment, good coping strategies, and good social support can prevent a negative impact on CLCI and major life-changing decisions

Retrospective Analysis of Inpatient Dermatologic Consultations in a Residency Training Program

Objective: This study assessed the prevalence and clinical characteristics of inpatient dermatologic diseases, examined trends over 3 academic years in a tertiary care hospital in Thailand, and evaluated their relevance to the current dermatology residency curriculum. Materials and Methods: A retrospective review was performed at the Department of Dermatology, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand. Consultation records from July 2018 to June 2021 were assessed. Data extracted included patient age, sex, referring departments, and diagnoses. Results: Of the 1964 consultations, 2002 diagnoses were identified. Consistent with previous findings, the predominant diagnostic categories were drug eruptions (28.02%; 561), eczema (16.18%; 324), and viral infections (9.29%; 186). Internal medicine made the most requests, followed by surgery and orthopedics. While the prevalence of consulted diseases remained constant over the 3 academic years, the total number of consultations increased. Most of the consulted conditions were already covered in the “must-know” section of the dermatology residency curriculum, with a few exceptions. The consultation cases satisfied the inpatient evaluation requirements of Entrustable Professional Activity. Conclusion: The prevalence of inpatient dermatologic diseases was highest for drug eruptions, followed by eczema and viral infections. The consistent trend in the prevalence of these consulted diseases underscores the significance of inpatient dermatology. Incorporating these insights into revisions of the dermatology residency curriculum may enhance the training of dermatologists

Polymorphic Eruption of Pregnancy Presented with Targetoid Lesions: A Report of Two Cases

Background: Skin lesions in pregnant women could be caused by physiologic or pathologic changes. Polymorphic eruption of pregnancy (PEP), which manifests as various types of skin lesions, is the most common pregnancy dermatosis. Thus, PEP could mimic other skin diseases related to unfavorable maternal and fetal outcomes. Main Observations: Two PEP patients with targetoid lesions are presented here. One of them was a primigravida, whereas the other was a secundigravida. Both patients had singleton pregnancies and skin rash which started during the third trimester. The lesions began on the abdomen and then spread to the trunk and extremities. The face, palms, soles, and mucosa were not affected. Pruritus was observed but no other systemic symptoms were reported. Both patients delivered healthy, term infants without complications. Conclusion: Targetoid lesions in PEP are an uncommon presentation, and the differential diagnosis of PEP along with other dermatoses should be considered. However, the prognosis for this type of PEP is not different from that for classic PEP

Cutaneous Miliary Tuberculosis in a Chronic Kidney Disease Patient

A 79-year-old Thai woman with advanced renal failure, dyslipidemia and anemia of chronic disease was admitted to hospital with prolonged fever, productive cough and multiple discrete small pustules on her face, trunk and extremities. A chest X-ray revealed diffuse miliary infiltration. Mycobacterium tuberculosis complex DNA was detected by polymerase chain reaction in sputum and scrapings of pustules from her skin. Blood culture identified M. tuberculosis complex. Pulmonary and cutaneous miliary tuberculosis was diagnosed. The patient's symptoms improved after 3 weeks of treatment with isoniazid, rifampicin, ethambutol and pyrazinamide. This report details a case of cutaneous miliary tuberculosis in a non-dialysis chronic kidney disease patient

Exploring adult-onset actinic prurigo in Thailand

Actinic prurigo (AP) is an uncommon photodermatosis. In European and native American populations, AP is more frequently found in young women and shows clinical improvement or remission in adulthood. The clinical symptoms of AP in Asians differ in that the condition usually occurs in adults (adult-onset AP) and is clinically persistent. The objective of this study is to investigate the characteristics and outcomes of patients with AP in Thailand. A total of 15 cases diagnosed AP were reviewed. All cases were adult-onset AP (mean age of onset was 45.5 years). Male predominated (66.7%). Mostly of them presented with papules on face and upper extremities. Mucositis was presented in 2 patients. Phototesting revealed decreased MED for UVA alone in 3 patients and decreased MED for both UVA and UVB in 3 patients. Nine patients who had normal MED were further performed photoprovocation test and showed positive UVA photoprovocation in 5 patients; positive both UVA and UVB photoprovocation in 4 patients. Systemic immunosuppressant was prescribed in 60% of patients. Median time to clinical improvement was 8.6 months. Complete clinical remission was found in only 3 patients. Adult-onset AP has different clinical features and responds differently to treatment, compared to classical AP

Proteomics in Psoriasis

Psoriasis has been thought to be driven primarily by innate and adaptive immune systems that can be modified by genetic and environmental factors. Complex interplay between inflammatory cytokines and T-cells, especially Th1 and Th17 cells, leads to abnormal cell proliferation and psoriatic skin lesions. Nevertheless, such mechanisms do not entirely represent the pathogenesis of psoriasis. Moreover, earlier and better biomarkers in diagnostics, prognostics, and monitoring therapeutic outcomes of psoriasis are still needed. During the last two decades, proteomics (a systematic analysis of proteins for their identities, quantities, and functions) has been widely employed to psoriatic research. This review summarizes and discusses all of the previous studies that applied various modalities of proteomics technologies to psoriatic skin disease. The data obtained from such studies have led to (i) novel mechanisms and new hypotheses of the disease pathogenesis; (ii) biomarker discovery for diagnostics and prognostics; and (iii) proteome profiling for monitoring treatment efficacy and drug-induced toxicities

Psoriasis and Risk of Uveitis: A Systematic Review and Meta-Analysis

Background. Uveitis is a known ophthalmologic manifestation of seronegative spondyloarthropathy, including psoriatic arthritis. However, the data is less clear among patients with psoriasis due to the limited number of published studies. Aims. To investigate whether the risk of incident and prevalent uveitis is elevated among patients with psoriasis using systematic review and meta-analysis technique. Methods. The MEDLINE and EMBASE databases were searched from their inception to May 2019. Eligible studies must have included a psoriasis group and a nonpsoriasis group. Eligible studies must also have investigated for prevalent or incident uveitis, and the magnitude of difference between the study groups must have been reported. Pooled risk ratio and 95% confidence interval (CI) were calculated using random-effect generic inverse variance methods. Results. Of 7,107 potentially eligible articles from the EMBASE and MEDLINE databases, 7 studies were included in the meta-analysis. Two of those studies compared the incidence, and 5 studies compared the prevalence of uveitis between the psoriasis and nonpsoriasis groups. For incident uveitis, a total of 5,865,801 patients (222,083 with psoriasis and 5,643,718 without psoriasis) were analyzed. For prevalent uveitis, a total of 1,343,436 patients (37,891 with psoriasis and 1,305,545 without psoriasis) were studied. The risk of incident uveitis was significantly higher among patients with psoriasis with a pooled risk ratio of 1.23 (95% CI: 1.05-1.45, I2=55%). The risk of prevalent uveitis was also significantly higher among patients with psoriasis with a pooled risk ratio of 1.97 (95% CI: 1.68-2.31, I2=0%). Conclusions. The results of this study revealed significantly increased risk of both prevalent and incident uveitis among patients with psoriasis
