A retrospective analysis of 65 patients with acrodermatitis continua of Hallopeau.

There are limited data on acrodermatitis continua of Hallopeau (ACH), particularly among Asian populations. The primary aim was to evaluate the clinical features of ACH and treatment approaches in a sizeable multicentre Asian cohort. We analysed data from adult patients diagnosed with ACH. Of 65 patients with ACH, seven patients had ACH with GPP. Females were more frequently affected in both conditions. Five (71.4%) developed GPP 5-33 years after ACH onset, while two (28.6%) developed GPP concurrently with ACH. The onset age for ACH with GPP (27.9 ± 13.6 years) was earlier than that of isolated ACH (39.8 ± 17.3 years). Metabolic comorbidities were common. ACH exhibited a chronic persistent course. Among systemic non-biologics, acitretin was the most frequently prescribed, followed by ciclosporin and methotrexate. Acitretin and ciclosporin demonstrated similar marked response rates, which surpassed that of methotrexate. Regarding biologics, a marked response was more commonly observed with interleukin-17 inhibitors than with tumour necrosis factor inhibitors. Females are predominant in both conditions. The onset age for ACH among Asian patients is earlier (late 30s) than that for Caucasian patients (late 40s). Interleukin-17 inhibitors may be more effective than tumour necrosis factor inhibitors in managing ACH.

The Steatosis-associated fibrosis estimator (SAFE) score for assessing significant liver fibrosis in psoriasis patients.

BACKGROUND: There is an urgent need for noninvasive tests to identify psoriasis patients at risk of significant liver fibrosis. OBJECTIVES: This study aimed to externally validate the ability of the steatosis-associated fibrosis estimator (SAFE) score to detect significant liver fibrosis in psoriasis patients using transient elastography (TE) as a reference. METHODS: We analyzed data from 75 psoriasis patients, including TE, SAFE score, FIB-4 index, and NAFLD fibrosis score. Significant liver fibrosis was defined as TE values ≥7.1 kPa. Diagnostic accuracy was assessed using the area under the receiver operating characteristic curve (AUROC). RESULTS: Fifteen patients (20%) exhibited significant liver fibrosis. The AUROCs for the SAFE and FIB-4 scores were 0.82 (95% CI, 0.67-0.97) and 0.62 (0.45-0.79), respectively. The SAFE score outperformed the FIB-4 index (P = 0.011) but was comparable to the NAFLD fibrosis score (P = 0.053) in predicting significant fibrosis. Using thresholds of <0, 0-<100, and ≥100, the SAFE score categorized 36, 24, and 15 patients into low, intermediate, and high-risk groups for significant fibrosis. The negative predictive value for excluding significant fibrosis with a SAFE score of <0 was 94.4%, and the positive predictive value for diagnosing significant fibrosis with a SAFE score of >100 was 53.3%. The duration of psoriasis, joint involvement, and methotrexate treatment, except the age of the patient, did not affect the diagnostic ability of the SAFE score. CONCLUSIONS: The SAFE score demonstrated good accuracy in assessing clinically significant fibrosis among psoriasis patients. This score should prove valuable for risk stratification and patient management in dermatology practice.

Dermatologists Should Encourage and Resume Photoprotection in Patients with Photodermatoses and Melasma Following the COVID-19 Pandemic.

Background: The COVID-19 pandemic may alter individuals' perspectives and behaviors regarding sun exposure and photoprotection. Presently, there is a paucity of information about how the pandemic influences photoprotection in photodermatoses and melasma. Objective: To compare the photoprotection attitudes and behaviors of individuals with photodermatoses and melasma with those of a control group (other dermatologic patients) before and during the COVID-19 pandemic. Methods: A questionnaire-based, cross-sectional study was conducted among Thai patients with photodermatoses, melasma, and other dermatological conditions between August 2021 and November 2022. Each of the three groups consisted of 35 patients. Results: Among the 105 patients, 81.9% were female, and the mean age was 45.83 years. Over 80% of individuals who used surgical masks daily for 4 to 8 hours believed that these masks provided skin protection from the sun. The duration of sun exposure and the frequency of photoprotection practices decreased significantly in all groups during the COVID-19 pandemic compared to the pre-pandemic period. Sunscreen was the most prevalent form of photoprotection, but its usage declined considerably during the pandemic. Upon physical examination, the photodermatoses and control groups exhibited unchanged skin conditions, while the patients with melasma demonstrated improved skin conditions during the pandemic. Conclusion: Owing to increased indoor activities and the perception that face masks could block sunlight, the COVID-19 pandemic led to notable reductions in sun exposure and photoprotective practices. Despite the absence of photodermatoses exacerbation and the observed improvements in patients with melasma, consistent and effective photoprotection must continue to be promoted.

Prevalence and clinical characteristics of pruritus, and the factors significantly associated with high pruritic intensity in patients with psoriasis: a cross-sectional study.

Despite the significant prevalence of pruritus in psoriasis, its pathogenesis remains unknown, and research on pruritus in Thai psoriasis patients is limited. Objectives: The objective was to investigate the prevalence and clinical characteristics of pruritus, and the factors significantly associated with high pruritic intensity in Thai psoriasis patients. Material and methods: In a cross-sectional study design, pruritus data were collected from the medical records of patients who attended an outpatient psoriasis clinic in Thailand between 2020 and 2021. Results: The overall prevalence of pruritus was 81.2% among 314 psoriasis patients. Psoriasis patients with pruritus had higher Psoriasis Area Severity Index and Dermatology Life Quality Index scores than those without pruritus. The legs, back, arms, and scalp were the most common areas for pruritus. Pruritus was relieved with topical emollients, topical corticosteroids, and oral antihistamines in 66.3, 63.1, and 52.9% of patients, respectively. Female sex, psoriasis body surface area greater than or equal to 10%, and genital psoriasis were factors that independently predicted high pruritus intensity. Conclusion: Psoriasis patients should be screened and treated for pruritus to improve both psoriasis treatment outcomes and patient quality of life. Further studies are needed to clarify the most effective medications for pruritus in patients with severe psoriasis.

The efficacy of bimatoprost ophthalmic solution combined with NB-UVB phototherapy in non-segmental and segmental vitiligo: a single-blind randomized controlled study.

Bimatoprost ophthalmic solution 0.03% (PGF2α analogues) combined with narrowband ultraviolet B (NB-UVB) was reported to be an effective treatment for vitiligo. To investigate the efficacy and safety of treatment for non-segmental/segmental vitiligo compared among bimatoprost ophthalmic solution 0.01% combined with NB-UVB phototherapy, bimatoprost monotherapy, and placebo. This single-blind randomized controlled study enrolled stable Thai vitiligo patients with at least three similarly sized lesions in the same anatomical area. The treatment duration was 6 months with 1- and 2-month post-treatment follow-ups. The 3 selected lesions on each patient were randomized to receive combination therapy, monotherapy, or placebo. The Vitiligo Area Scoring Index (VASI) was used to evaluate lesion response. Of the 25 initially enrolled subjects, 19 patients were analyzed. There were 13 and 6 non-segmental and segmental vitiligo cases, respectively. Eight and 11 cases had face/neck and non-face/neck lesions, respectively. Non-segmental vitiligo and non-face/neck vitiligo patients in the combination group had significant improvement in VASI score at 3 months, 6 months, and at the 2-month follow-up. No side effects were observed/reported. Bimatoprost combination therapy was shown to be safe and effective for treating Thai patients with non-segmental vitiligo in non-face/neck areas of the body.

Do different platforms of coronavirus vaccines have different impacts on psoriasis flares?

This study evaluated the impacts on psoriasis flares of 3 vaccine platforms: inactivated, viral vector and mRNA. Respectively, 198 and 96 psoriasis patients with and without COVID-19 vaccination during the study period. Group comparison revealed no increased risk of psoriasis flaring after COVID-19 vaccination. The vaccinated group received 425 doses of vaccine (140 inactivated, 230 viral vector and 55 mRNA). Patients' self-reported symptoms included all three platforms causing psoriasis flare, but the highest was among patients administered with mRNA vaccines. Most flares were mild to moderate, and most patients (89.8%) managed their flare-up lesions without rescue therapy. In conclusion, our study showed that the rate of psoriasis flare was not significantly different between vaccinated and unvaccinated groups. Factors that might explain psoriasis flare include vaccine-related psychological stress and side effects from vaccination. Different platforms of corona vaccines seemed to have different impact of psoriasis flares. Based on our results and the recommendations of several consensus guidelines, the benefits of COVID vaccinations outweigh the risks to patients with psoriasis. Patients with psoriasis should receive a COVID vaccine as soon as one is available.

An analysis of psoriasis hospitalisation in Thailand.

Psoriasis hospitalisation is not frequently reported. The objective of this study was to determine (1) the clinical, laboratory and treatment features of patients with psoriasis hospitalised due to flare-up and (2) other causes of admission of patients with psoriasis. We retrospectively reviewed data on 48 patients admitted due to psoriasis flare-up and 1908 patients with psoriasis admitted due to concomitant illnesses or comorbidities. The study period was 2005-2021. The latter group was compared with 821,804 patients without psoriasis admitted during the period. Of the 48 cases, 37.5% had erythroderma, and 62.5% had generalised pustular psoriasis (GPP). Women (68.8%) predominated, especially in the GPP group (76.7%). The mean age of admission with erythroderma (44.8 years) was higher than for GPP (32.1 years). Infection was the main trigger for psoriasis flare-up (46%). Abnormalities in liver function tests were found in 33.3% of the cases. These abnormalities usually subsided 1-2 months after skin improvement (83.4%). Acitretin was the most prescribed drug for GPP (81.4%), whereas topical treatment alone (50%) was the most frequent erythroderma therapy. Intensive care was needed by 9.3% of patients with GPP. In the psoriasis group admitted due to concomitant illnesses or comorbidities, admission due to digestive and infectious causes was significantly higher for psoriasis patients. Our study showed that trend of psoriasis admission due to disease flare-up was not significantly changed even in the era of biologics. We believed that patient education on avoiding the common precipitating factors of psoriasis flare-up and good self-care is mandatory to reduce the risk of hospitalisation.

Prevalence of Depressive Symptoms and Their Impact on Perceived Stress and Quality of Life Among Patients with Psoriasis.

Objective: This study aimed to investigate the prevalence of depressive symptoms in patients with psoriasis and the association between depressive symptoms, perceived stress level, and quality of life of the participants. Methods: Patients with psoriasis were invited to complete the Thai versions of the Patient Health Questionnaire, Perceived Stress Scale-10, Psoriasis Disability Index, and Simplified Psoriasis Index. To identify significantly related factors of depression, the independent sample t-test or Mann-Whitney U-test was performed to compare continuous variables between groups, and the chi-square test or Fisher's exact test was used to compare categorical variables between groups. The association between the severity of depression and other variables was examined using Spearman's correlation coefficient. Results: Of the 150 participants assessed, 32 (21.3%) had depressive symptoms. Elevated stress scores, subjective psychosocial impact of psoriasis, self-perceived current severity of psoriasis, and impaired quality of life were significantly associated with depressive symptoms. Depressive symptom severity was determined to be positively correlated with perceived stress, quality-of-life impairment, current severity, and the psychosocial impact of psoriasis. Conclusion: Depressive symptoms are prevalent among patients with psoriasis. Those with high scores for perceived stress, a psychosocial impact of psoriasis, or disease severity should be evaluated for depression, as it can hamper their quality of life.

The Anti-Psoriatic Efficacy and Safety Profile of Topical and Intralesional Methotrexate: A Literature Review.

Methotrexate (MTX) has long been considered the first-line oral systemic pharmacotherapy for psoriasis. The drug has several well-known systemic side effects, such as bone marrow suppression and hepatotoxicity. To avoid them, the use of topical or intralesional administrations of MTX has become an interesting option. With the advent of novel drug delivery systems, especially nanocarriers, the usage of a high-efficacy and safe topical MTX for psoriasis has nearly been attained. This review examined the development, anti-psoriatic efficacy and adverse effects of topical forms of MTX (plain MTX; MTX with chemical enhancer; MTX using nanotechnology; MTX with protein transduction domains; MTX with liquid crystalline systems; and MTX with physical enhancer/laser) and intralesional MTX in psoriasis patients and psoriasis-induced animals. The efficacy of topical MTX varied with the drug delivery technology employed. Nevertheless, the overall safety profile of the topical forms was favourable. A 25 mg/mL MTX solution injected intralesionally at the nail matrix worked well for nail psoriasis recalcitrant to topical treatment. To improve the standard of care for patients with psoriasis, randomized controlled trials that establish the most effective MTX-delivery system are needed.

Retrospective study of psoriasis in people living with HIV: Thailand's experience.

Psoriasis in people living with HIV (PLHIV) has been reported as having particular clinical characteristics. However, most of the source data was derived from descriptive studies in Europe and the USA. This study was conducted to compare the characteristics of psoriasis in PLHIV to general psoriasis patients. We retrospectively reviewed the records of 73 cases of psoriasis in PLHIV and of 232 general psoriasis patients who visited a psoriasis clinic in Bangkok, Thailand. Psoriasis in PLHIV predominated in males (78.1%), with an older age of onset, significantly lower rates of nail involvement and psoriatic arthritis, but higher rates of co-infectious diseases than for general psoriasis patients. A low nadir CD4 T-cell count (<100 cells/µl) and CD4 T-cell count at psoriasis diagnosis were associated with a high body surface area (BSA) involvement. The mean BSA involvement in PLHIV was 24. Although 64.4% (47/73) of the PLHIV had moderate-to-high psoriasis severity, 29.8% of those (14/47) only received topical treatment. Acitretin was the most common drug used. Other therapies were rarely used, and no biologics were administered. In conclusion, psoriasis in PLHIV has several clinical features that differ from general psoriasis. PLHIV tend to receive substandard care for psoriasis, even in upper-middle-income countries.

Using the patient-acceptable symptom state to evaluate patients' perspectives of living with psoriasis: A cross-sectional study.

BACKGROUND: Taking the perspectives of patients into consideration is of the utmost importance when defining treatment goals for psoriasis. The patient-acceptable symptom state (PASS) is a dichotomised question that captures patients' perceptions of their overall health state. OBJECTIVES: To evaluate PASS and determine the factors associated with a satisfactory PASS for psoriatic patients. METHODS: Three questions were asked: (Q1) Considering the ways that your skin symptoms affect your functioning, is your current skin psoriasis satisfactory? (Current PASS), (Q2) Considering the ways that your psoriasis is affecting you, if you were to remain in this state for the next few months, would this be satisfactory? (Future PASS) and (Q3) If you were to remain for the rest of your life as you were during the last 48 hours, would this be satisfactory? (Lifelong PASS). Disease severity, symptoms and health-related quality of life (HRQoL) were collected. RESULTS: Of 140 patients, 74.3%, 70.0% and 85.7% expressed satisfaction with their current, future and lifelong skin psoriasis conditions respectively. A satisfactory PASS was significantly associated with older and married patients; lower disease severity; fewer skin symptoms; and a higher HRQoL. A multivariate analysis revealed that the independent factors associated with a satisfactory PASS were being older than 40 years, being married, practising meditation, not having extensive lesions at sensitive areas and having a high HRQoL. CONCLUSIONS: PASS is a simple and easily administered questionnaire that reflects both disease severity and HRQoL. Understanding patients' needs and satisfaction levels will result in better care for psoriatic patients than otherwise.

Outcomes of autologous non-cultured melanocyte keratinocyte transplantation in vitiligo and nevus depigmentosus.

BACKGROUND: Melanocyte-keratinocyte transplantation procedure (MKTP) is an effective surgical technique for restoring skin pigmentation in all types of vitiligo and leukoderma patients who are unresponsive to medical and/or phototherapy treatment. Data specific to the outcomes of MKTP among Thai vitiligo and nevus depigmentosus patients are currently scarce. OBJECTIVES: To evaluate the efficacy and safety of MKTP in patients with vitiligo or nevus depigmentosus at the short-term (≤6 months) and long-term (≥12 months) follow-up. MATERIALS AND METHODS: A retrospective review of the medical records of vitiligo or nevus depigmentosus patients who underwent MKTP at the Department of Dermatology, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand during 2016 to 2019 was conducted. Repigmentation outcomes were evaluated by Vitiligo Area Scoring Index (VASI). RESULTS: Twenty-five patients had 27 MKTP surgeries on 32 anatomically-based lesions. The mean age was 32.4 years, the mean age at onset was 25.5 years, and 19 patients were male. Segmental vitiligo, non-segmental vitiligo, and nevus depigmentosus had significantly improved VASI scores at the short-term follow-up (-74.2% ± 23.2%, -100%, and -62.5% ± 17.6%, respectively) and the long-term follow-up (-81% ± 27.7%, -95.0% ± 7.0%, and -83.3% ± 14.4%, respectively). CONCLUSION: MKTP is a safe and effective method for treating refractory vitiligo and nevus depigmentosus in Thai patients.

Patient-ready syringes containing 25 mg/mL methotrexate can be kept at temperature ranging from 4 °C to 37 °C for up to 12 weeks for use in psoriatic and rheumatologic conditions.

BACKGROUND: Methotrexate (MTX) is a mainstay drug in the treatment of psoriatic and rheumatologic conditions. Subcutaneous MTX has become a feasible treatment alternative with the development of prefilled syringes or autoinjectors containing MTX solution that can be self-administered by the patient at home. However, MTX prefilled auto-injector pens are still not available in some countries. OBJECTIVE: This study aimed to investigate the stability and sterility of 25 mg/mL MTX solution in a disposable plastic syringe over a 12-week period under light protection at temperatures of 4 °C, 25 °C, and 37 °C. METHODS: This study was conducted during November 2019 to February 2020 at the Faculty of Medicine Siriraj Hospital, Mahidol University. Stability was evaluated using ultra-high-performance liquid chromatography technique, and sterility was assessed by cultures for bacterial and fungal contamination. RESULTS: Our results revealed that patient-ready syringes containing 25 mg/mL MTX solution can be prepared in advance and kept for up to 12 weeks under light protection, and they can be kept at temperatures ranging from 4 to 37 °C. CONCLUSION: This system for delivering MTX to patients that are refractory to or intolerant of oral MTX via a self-administered pre-filled syringe is both efficient and easy to implement in care settings where commercially alternatives are not yet available.

Dietary habits and perceptions of psoriatic patients: Mediterranean versus Asian diets.

BACKGROUND: Mediterranean diets have been reported to improve psoriasis. Asian food has a unique character and differs from Mediterranean diets. METHODS: This study compared the dietary intake of psoriatic patients and individuals without psoriasis, and investigated the association between diet and psoriasis severity. Data were collected on the frequency of consumption of Mediterranean and Asian diets. RESULTS: One-hundred psoriatic patients and 100 individuals (age- and sex-matched controls) was conducted. In the case of the anti-inflammatory diets, the psoriatic patients consumed significantly less olive oil, berry fruits, fish, seafood, tree nuts, and eggs than the controls. As to the pro-inflammatory diets, greater quantities of dairy products and soft drinks were consumed by the psoriatic patients than the controls. Regarding Asian food, the patients consumed significantly less pickled foods and brown rice/Riceberry (a rice variety), but more coconut milk, than the controls. In terms of psoriasis severity, the patients with lower severities consumed significantly more vegetables; in contrast, a higher consumption of red meat, belly meat, and instant noodles was associated with greater psoriasis severities. CONCLUSIONS: Our study adds further information on the role of diets-especially Asian diets-and psoriasis. These data should help patients and clinicians to focus more clearly on diet management.

Reliability, Validity and Feasibility of the Vitiligo Extent Score (VES) and Self-Assessment Vitiligo Extent Score (SA-VES) Among Vitiligo Patients: A Cross-Cultural Validation.

BACKGROUND: The Vitiligo Extent Score (VES) and Self-Assessment Vitiligo Extent Score (SA-VES) have not been formally validated in Thai population. OBJECTIVE: To evaluate reliability, validity and feasibility of the VES and SA-VES in Thai vitiligo patients. METHODS: Vitiligo lesions from 100 patients were evaluated by 2 independent dermatologists using VES and Vitiligo Area Scoring Index (VASI). Reliability was assessed by comparing VES scores between physicians. Validity was determined by comparison among the VES, VASI, and SA-VES instruments. Patients scored their vitiligo severity using the SA-VES. RESULTS: The reliability of the VES was excellent (inter-rater reliability: 0.997, 95% confidence interval: 0.995-0.998). There was very strong correlation between the VES and VASI (r=0.976, p<0.001), and strong correlation between the VES and SA-VES (r=0.890, p<0.001), and between the VASI and SA-VES (r=0.866, p<0.001). Moderate correlation among the VES, VASI, and SA-VES was observed in patients with segmental or <1% body surface area (BSA) vitiligo. Ninety-five percent of patients rated the SA-VES as easy to moderately easy. CONCLUSION: The VES has reliability and validity comparable to that of the VASI. The SA-VES is an user-friendly instrument that correlated well with physicians' scoring methods in patients with non-segmental or >1% BSA vitiligo.

An evaluation of the course of facial sunscreen coverage and sustainability over an 8-hour workday among outdoor workers.

BACKGROUND: Reapplication of sunscreen every 2 hours is recommended, especially after swimming, sweating, or working outdoors. However, the sustainability of sunscreen during the workday among outdoor workers is still unclear. OBJECTIVE: To evaluate the course of facial sunscreen coverage and sustainability over an 8-hour workday among outdoor workers. MATERIALS AND METHODS: This open-label trial included 20 healthy subjects who spend at least 80% of their workday outdoors. All volunteers applied 2 mg/cm2 of provided broad-spectrum sunscreen mixed with the invisible blue fluorescent agent to all parts of their face in the morning. A VISIA-CR camera was used to capture facial fluorescence intensity every 2 hours, and digital image analysis software was used to quantify fluorescence intensity at six areas of the face at each time point for 8 hours. RESULTS: Sunscreen coverage declined most rapidly during the first 2 hours with a mean reduction of 18.31%. By the end of the 8-hour study workday, the mean decrease in sunscreen coverage was 31.63% (range: 17.39%-45.29%). CONCLUSION: Reapplication of sunscreen is essential among outdoor workers. After 4 hours, the amount of sunscreen remaining on the face may not be sufficient for protecting the skin from harmful ultraviolet radiation.

How do we treat psoriasis patients with hepatitis C infections in real-world situations? A retrospective analysis of 34 patients.

BACKGROUND: There is still relatively limited data on psoriasis and hepatitis C virus (HCV) infections. OBJECTIVE: This study investigated the clinical characteristics and treatment of psoriasis patients with HCV infections in real-world practice. METHODS: Medical records of all psoriasis patients with HCV infections who attended the outpatient clinic at Siriraj Hospital over a 10-year period were retrospectively reviewed. RESULTS: Of 34 patients, 26 and 8 patients were men and women, respectively with a mean age of 57.0 ± 8.7 (range, 42.2-77.2) years. The median age of psoriasis onset was 42.7 ± 12.7 (range, 8-67.25) years. With a median follow-up period of 13.6 years, cirrhosis and hepatocellular carcinoma were found in 67.6% and 29.4% of the patients, respectively. The interferon used for HCV treatment exacerbated the psoriasis in 20% of those patients. Conventional treatments and anti-tumor necrosis factors (anti-TNFs) were used in strict collaboration with hepatologists. No patients experienced a worsening of their HCV infection. CONCLUSION: Despite a limited number of patients, a male predominance and late-onset psoriasis were frequently observed. Although, interferon therapy for HCV can exacerbate psoriasis, it is not contraindicated. All conventional treatments and anti-TNFs can be used, provided that there is strict collaboration with hepatologists.

Relationship Between Depression and Quality of Life Among Vitiligo Patients: A Self-assessment Questionnaire-based Study.

BACKGROUND: Vitiligo is a common chronic autoimmune disease that is characterized by progressive loss of skin color due to melanocyte destruction. In addition to the physical effects of vitiligo, this condition exerts adverse psychological effects and causes social stigmatization. Earlier studies reported that individuals with vitiligo suffer from poor quality of life (QoL), but data about the QoL of Thai vitiligo patients is scarce. OBJECTIVE: This study aimed to investigate the QoL and prevalence of depression in Thai vitiligo patients, association between QoL and depression, and factors associated with QoL and depression among Thai people with vitiligo. METHODS: This cross-sectional self-assessment questionnaire-based study was conducted at the phototherapy and vitiligo clinics of the Department of Dermatology, Faculty of Medicine Siriraj Hospital, Mahidol University (Bangkok, Thailand). QoL was assessed using the Dermatology Life Quality Index (DLQI) questionnaire, and depression was evaluated via the Patient Health Questionnaire (PHQ-9). RESULTS: Among the 104 vitiligo patients that were recruited, the mean DLQI score was 7.46, and the prevalence of depression (PHQ-9 ≥9) was 13.5%. Factors significantly associated with a higher mean DLQI score were skin phototype IV compared to phototype III, active disease, new lesions within the last three months, lesions involving upper extremities, and PHQ-9 ≥9 (p<0.05). Moderate correlation was found between DLQI score and PHQ-9 score (Pearson's correlation coefficient: 0.524, p<0.001). Factors significantly associated with depression were working status and developing new lesions within the last three months (p<0.05). Patients with new lesions were 4.12 times more likely to be depressed than those without new lesions (OR: 4.12, 95%CI: 1.20-14.16; p=0.025). CONCLUSION: Developing new lesions, active disease, dark skin phototype (IV), and lesion on upper extremity had significant adverse effects on QoL. Vitiligo patients who were employed and who had new vitiligo lesions are significantly more likely to be depressed.

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, I 2 = 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, I 2 = 0%). CONCLUSIONS: The results of this study revealed significantly increased risk of both prevalent and incident uveitis among patients with psoriasis.

Impact of long-term systemic treatment for psoriasis on liver disease in psoriasis patients with coexisting hepatitis B virus infection.

Continuously updated information is helpful for evaluating the safety of long-term systemic drug use in psoriasis patients with concomitant hepatitis B virus (HBV) infection. To investigate the impact of long-term systemic treatment for psoriasis on liver disease in psoriasis patients with HBV infection. Data of patients during 10-year period were recorded and analyzed. Sixty-six patients (46 males and 20 females) with a mean age of 58.5 ± 13.1 years were recruited. Our study estimated that the 5-year cumulative risks of developing cirrhosis and HCC were 30% and 5%, respectively, in patients receiving systemic treatments for psoriasis. Risks of cirrhosis and HCC were not significantly different between systemic and topical treatment groups. Thirty patients were prescribed systemic treatments (acitretin, methotrexate, ciclosporin, and anti-tumor necrosis factors). Three HBsAg+ patients developed viral reactivation (two patients with methotrexate and one patient with ciclosporin). The effects of systemic treatments for psoriasis on liver outcome in patients with coexisting HBV infection are needed to be determined. HBsAg+ patients are more likely to develop viral reactivation during systemic treatment for psoriasis than HBsAg- patients. Monitoring of liver enzymes and HBV DNA every 3 months is recommended during treatment and for 6 to 12 months after drug discontinuation.
