    All around the world, there is growing evidence of the association between psoriasis and comorbidities which increase the risk of cardiovascular disease. This study aims to determine the prevalence of various comorbidities among adult psoriasis patients in Malaysia. A cross-sectional study was conducted among patients in the Malaysian Psoriasis Registry from January 2007 to December 2008. A total of 2,267 adult patients with psoriasis from 13 dermatology centers were included. Prevalence of various comorbidities were: hypertension 25.9%, diabetes mellitus 17.7 %, dyslipidaemia 17.8%, overweight 33.2%, obesity 20.7%, ischaemic heart disease 5.8% and cerebrovascular disease 1.4%. These comorbidities were more prevalent in patients with psoriasis of late-onset and longer duration. Active screening of these comorbidities in all adult psoriasis patients is recommended.

    Background: Psoriasis is a chronic inflammatory skin disease affecting 2-3% of the general population.
    Aim: To evaluate the epidemiology and clinical characteristics of patients with psoriasis who seek treatment in outpatient dermatology clinics throughout hospitals in Malaysia.
    Materials and Methods: Data were obtained from the Malaysian Psoriasis Registry (MPR). All patients (aged 18 and above) who were notified to the registry from July 2017 to December 2017 were included in this study.
    Results: Among 15,794 patients, Malays were the most common (50.4%), followed by Chinese (21.4%), Indian (17.6%), and others (10.6%). The mean age onset of psoriasis for our study population was 35.14 ± 16.16 years. Male to female ratio was 1.3 : 1. 23.1% of patients had positive family history of psoriasis. The most common clinical presentation was chronic plaque psoriasis (85.1%), followed by guttate psoriasis (2.9%), erythrodermic psoriasis (1.7%), and pustular psoriasis (1.0%). Majority of our patients (76.6%) had a mild disease with BSA < 10%. 57.1% of patients had nail involvement, while arthropathy was seen in 13.7% of patients. Common triggers of the disease include stress (48.3%), sunlight (24.9%), and infection (9.1%). Comorbidities observed include obesity (24.3%), hypertension (25.6%), hyperlipidemia (18%), diabetes mellitus (17.2%), ischaemic heart disease (5.4%), and cerebrovascular disease (1.6%). The mean DLQI (Dermatology Life Quality Index) was 8.5 ± 6.6. One-third (33.1%) of the patients had a DLQI score of more than 10, while 14.2% of patients reported no effect at all.
    Conclusion: Our study on the epidemiological data of adult patients with psoriasis in Malaysia showed a similar clinical profile and outcome when compared to international published studies on the epidemiology of psoriasis.

    Generalized pustular psoriasis (GPP) is a rare, potentially life-threatening disease characterized by episodes of widespread sterile macroscopic pustules, with or without systemic inflammation and/or plaque psoriasis. Multiple GPP subtypes have been described, from acute GPP of von Zumbusch to milder, annular pustular psoriasis. Generalized pustular psoriasis mainly affects adults, with a female preponderance, but juvenile GPP also occurs. Flares are a hallmark of GPP and may occur de novo or be provoked by triggers, including withdrawal of systemic corticosteroids, infections, stress, pregnancy, and menstruation. Severity of flares varies widely between patients, and between flares in an individual patient. Significant flares are often accompanied by systemic symptoms, notably fever, general malaise, and extracutaneous manifestations such as arthritis, uveitis, and neutrophilic cholangitis. Common laboratory abnormalities include neutrophilia, elevated C-reactive protein levels, hypocalcemia, and abnormal liver function tests. The clinical course of GPP is highly variable; it can be a relapsing disease with recurrent flares and no pustulation between flares or a persistent disease with perpetual mild pustulation punctuated with flares of greater severity. Patients may have multiple flares per year or a flare every few years. Most flares last 2-5 weeks and approximately 50% require hospitalization. Life-threatening complications include sepsis and renal, hepatic, respiratory, and heart failure. Reported mortality rates are 2-16%.

    Generalized pustular psoriasis (GPP) is a rare neutrophilic skin condition characterized by episodes of widespread eruption of sterile macroscopic pustules that can be associated with systemic inflammation. The rarity of GPP and its heterogeneous cutaneous and extracutaneous symptoms pose considerable challenges to the development and adoption of comprehensive accurate disease measures for the routine clinical assessment of disease severity and the evaluation of new treatments in clinical trials. Psoriasis disease measures remain among the most commonly used methods for evaluating patients with GPP, despite their limitations owing to a lack of assessment of pustules (a hallmark of GPP), systemic inflammation, and disease symptoms. The adaptation of psoriasis disease measures and the development of assessment tools specific for GPP severity will enable more effective and accurate monitoring of patients with GPP and enhance the clinical development of new therapies. Further clinical validation of recently developed modified assessment tools, such as the Generalized Pustular Psoriasis Physician Global Assessment and the Generalized Pustular Psoriasis Area and Severity Index, and international consensus on using quantitative tools and patient-reported outcome measures in the development of new treatments are needed to advance patient care.

    BACKGROUND: Psoriasis is a complex chronic inflammatory skin disease with a worldwide distribution.
    OBJECTIVE: To determine the prevalence of psoriasis according to age, gender and ethnicity among outpatients attending the dermatology clinic in Hospital Tengku Ampuan Rahimah, Klang Malaysia.
    STUDY POPULATION: All outpatients attending the specialist clinic of the dermatology department in Hospital Tengku Ampuan Rahimah, Klang, Malaysia from January 2003 to December 2005.
    METHODS: This is a retrospective descriptive study of all outpatients who attended the specialist clinic from January 2003 to December 2005 and diagnosed for psoriasis. The study population consisted of patients of all ages, both gender and different ethnic groups (Malay, Chinese, Indians and foreign workers) living in the Klang Valley and the surrounding areas.
    RESULTS: A total of 5607 patients were examined during a period of three years and 9.5% were found to be suffering with psoriasis. It was more common in males (11.6%) than in females (7.2%). Patients within the 40-60 year age group had the highest (17.2%) rate and were lower in the younger age group including those aged over 60 years (8.1%). With regards to ethnicity, it was more common in Indians followed by Malays, Chinese and migrant foreign workers respectively. The study indicates that psoriasis is common in Malaysia and its distribution varies with age, ethnicity and gender.

    Generalized pustular psoriasis is a potentially life-threatening neutrophilic skin disease characterized by recurrent flares of widespread erythema and eruption of sterile pustules. In the Effisayil™ 1 study (NCT03782792), 53 patients with a generalized pustular psoriasis flare were treated with placebo or spesolimab, a humanized anti-interleukin-36 receptor monoclonal antibody, the first targeted treatment to be studied in a randomized clinical trial. Spesolimab treatment resulted in rapid pustular and skin clearance, with an acceptable safety profile. Here, we evaluate the efficacy and safety of spesolimab in 29 Asian patients in the Effisayil™ 1 study. The primary endpoint, a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) pustulation subscore of 0 (no visible pustules) at Week 1, was achieved by 10 patients (62.5%) randomized to spesolimab and one patient (7.7%) randomized to placebo (risk difference 54.8, 95% confidence interval [CI] 17.3-79.8). The key secondary endpoint, a GPPGA total score of 0 or 1 (clear or almost clear skin) at Week 1, was achieved by eight (50.0%) and two (15.4%) patients, respectively (risk difference 34.6, 95% CI -3.1-64.7). This was similar to previously published data in the overall population in whom the primary and key secondary endpoints were achieved by 54% versus 6% and 43% versus 11% of patients, respectively. The percentages of Asian patients randomized to spesolimab with a GPPGA pustulation subscore of 0 and GPPGA total score of 0 or 1 were sustained above 60% for up to 12 weeks. In these patients, patient-reported outcomes also improved and markers of systemic inflammation were normalized. Eleven (68.8%) and eight (61.5%) of spesolimab- and placebo-treated patients, respectively, experienced at least one adverse event. In conclusion, spesolimab improved outcomes in Asian patients compared with placebo, supporting its use in the treatment of generalized pustular psoriasis flares.

    Effisayil 1 was a multicentre, randomized, double-blind, placebo-controlled study of the anti-interleukin (IL)-36 receptor monoclonal antibody, spesolimab, in patients presenting with a generalized pustular psoriasis (GPP) flare. Previously published data from this study revealed that within 1 week, rapid pustular and skin clearance were observed in patients receiving spesolimab versus placebo. In this pre-specified subgroup analysis, the efficacy of spesolimab was evaluated according to patient demographic and clinical characteristics at baseline in patients receiving spesolimab (n = 35) or placebo (n = 18) on Day 1. Efficacy was by assessed by achievement of primary endpoint (Generalized Pustular Psoriasis Physician Global Assessment [GPPGA] pustulation subscore of 0 at Week 1) and key secondary endpoint (GPPGA total score of 0 or 1 at Week 1). Safety was assessed at Week 1. Spesolimab was found to be efficacious and had a consistent and favourable safety profile in patients presenting with a GPP flare, regardless of patient demographics and clinical characteristics at baseline.

    Psoriasis is an immune-mediated skin disorder associated with severe systemic comorbidities. Whereas IL-36 is a key disease driver, the pathogenic role of this cytokine has mainly been investigated in skin. Thus, its effects on systemic immunity and extracutaneous disease manifestations remain poorly understood. To address this issue, we investigated the consequences of excessive IL-36 activity in circulating immune cells. We initially focused our attention on generalized pustular psoriasis (GPP), a clinical variant associated with pervasive upregulation of IL-36 signaling. By undertaking blood and neutrophil RNA sequencing, we demonstrated that affected individuals display a prominent IFN-I signature, which correlates with abnormal IL-36 activity. We then validated the association between IL-36 deregulation and IFN-I over-expression in patients with severe psoriasis vulgaris (PV). We also found that the activation of IFN-I genes was associated with extracutaneous morbidity, in both GPP and PV. Finally, we undertook mechanistic experiments, demonstrating that IL-36 acts directly on plasmacytoid dendritic cells, where it potentiates toll-like receptor (TLR)-9 activation and IFN-α production. This effect was mediated by the upregulation of PLSCR1, a phospholipid scramblase mediating endosomal TLR-9 translocation. These findings identify an IL-36/ IFN-I axis contributing to extracutaneous inflammation in psoriasis.

    Ustekinumab adalah agen biologi yang berkesan untuk rawatan kulit psoriasis dengan menyasarkan molekul interleukin 12 dan 23. Namun begitu ada beberapa halangan ketika penggunaannya seperti kegagalan sekunder dan juga peristiwa paradoks. Penyakit juga didapati kembali menyerang selepas terapi dihentikan. Kajian kohort retrospektif telah dilakukan ke atas pesakit kulit kronik psoriasis yang telah menerima ustekinumab di antara tahun 2013 ke 2018 di Pusat Perubatan Universiti Kebangsaan Malaysia (PPUKM). Demografi, ciri-ciri klinikal, keberkesanan rawatan, komplikasi, kadar dan corak penyakit berulang dikaji melalui rekod-rekod pesakit. Enam (75%) pesakit adalah lelaki. Enam (75%) pesakit ini tidak pernah menerima agen biologi sebelum ini. Usia median pesakit adalah 41.5 tahun (IQR 26.8-48.3), tempoh median penyakit ialah 16.5 tahun (IQR 6.5- 23.0). Tempoh median untuk mencapai kadar 75% pengurangan penyakit (PAS I75) adalah 16 minggu. PASI75 pada minggu ke 12 dicapai oleh 37.5% pesakit manakala tempoh median untuk mencapai sekurang-kurangnya PASI75 adalah 16 minggu. Tempoh median keseluruhan rawatan adalah selama 102 minggu. Semua pesakit berjaya dirawat. Dua (25%) pesakit mengalami kegagalan sekunder. Seorang (12.5%) pesakit mendapat peristiwa paradoks dengan tumbuhnya fenomena nanah dan plak di kulit semasa rawatan. Tempoh median untuk penyakit berulang adalah 40 minggu. Semua pesakit kecuali seorang memerlukan rawatan biologi untuk penyakit berulang. Ustekinumab berkesan untuk semua pesakit. Kejayaan rawatan diperolehi 4 minggu selepas piawai yang dijangkakan. Kohort ini telah merekodkan kegagalan sekunder dan fenomena paradoks yang jarang berlaku. Penyakit didapati akan berulang dan corak psoriasis yang berbeza ditemui selepas rawatan dihentikan.

    Erythroderma can be life-threatening, primarily because of its metabolic burden and complications. It is mandatory to establish its etiopathology in order to facilitate precise and definitive management. This disorder may be the morphologic presentation of a variety of cutaneous and systemic diseases. Detailed history and thorough work-up is therefore essential. Management of erythroderma involves multi-disciplines with progress monitoring especially on signs and symptoms suggestive of acute skin failure induced complications. Early diagnosis and referral of erythroderma to centres with dermatological services is crucial and will directly affect the outcome of the patients.

    Psoriasis is a chronic inflammatory skin disease characterized by thickened, silvery-scaled patches. There is currently no cure and treatments only attempt to reduce the severity of symptoms. This study reports the case of a 36-year-old female who presented to the clinic with severe psoriasis and had been treated with topical steroid cream for the past 14 years. After adherence to prescribed dietary changes for 6 months, including abundant intake of vegetables, minimal consumption of meat, and avoidance of junk food and sugar in food or drinks, as well as nutritional supplementation with Vitacor Plus, ProLysinC, VitaCforte and LysinC Drink mix, the patient experienced complete resolution of psoriatic patches on her body.

    Psoriasis is a skin disorder which is caused by a genetic fault. Although there is no cure for psoriasis, there are many treatment modalities to help control the disease. To evaluate treatment efficacy, the current gold standard method, PASI (Psoriasis Area and Severity Index), is used to measure psoriasis severity by evaluating the area, erythema, scaliness and thickness of the plaques. However, the determination of PASI can be tedious and subjective. In this work, we develop a computer vision method that determines one of the PASI parameters, the lesion area. The method isolates healthy and healed skin areas from lesion areas by analysing the hue and chroma information in the CIE L*a*b* colour space. Centroids of healthy skin and psoriasis in the hue-chroma space are determined from selected sample. The Euclidean distance of all pixels from each centroid is calculated. Pixels are assigned to either healthy skin or psorasis lesion classes based on the minimum Euclidean distance. The study involves patients from different ethnic origins having three different skin tones. Results obtained show that the proposed method is able to determine lesion areas with accuracy higher than 90% for 28 out of 30 cases.

    A prospective clinical study of 181 patients with psoriasis seen in Seremban General Hospital showed the incidence of psoriasis among dermatology outpatients was 2.15%. A significantly higher proportion of male patients were affected, with a male to female ratio of 1.7:1. Within the racial groups; 63 were Malays, 37 Chinese, and 81 Indians. There was a significantly higher proportion of Indians affected as compared with the races. The mean age of patients in this study was 43.7 years old but the mean age of onset of psoriasis in these patients was 33.1 years old. Thirty-one (17.1%) patients gave a positive family history of psoriasis and the mean age of onset of psoriasis was lower (29.3 years old) for patients with a positive family history. Plaque psoriasis was the commonest type of clinical presentation with the scalp being the commonest site affected. Psoriatic arthropathy was seen in 35 (19.3%) patients. Ninety-five (52.5%) patients gave a positive history of factors exacerbating their pre-existing disease and stress was singled out as the most common exacerbating factor.
