PMID: 15727378 MyJurnal

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.

CONTEXT: Acitretin increases serum lipids. Data on its effects on insulin resistance and glucose metabolism are sparse and contradicting.
AIMS: The aim of this study is to investigate the effects of acitretin on insulin resistance, glucose metabolism, and lipids.
METHODS: Dermatology clinic in a public tertiary hospital. A cross sectional study involving chronic plaques psoriasis patients on acitretin plus topical therapy or topical therapy alone was performed. Fasting blood glucose (FBG), serum lipids, serum insulin, and glucose tolerance test (GTT) were performed. Homeostatic model of insulin resistance (HOMA-IR) was calculated. Psoriasis severity was evaluated using Psoriasis Area and Severity Index. Chi square and t-tests determined differences between cases and controls. Pearson's correlation coefficient test determined the relationship between continuous variables.
RESULTS: A total of 60 patients participated, 30 were on acitretin while 30 were on topical therapy. Psoriasis duration, disease severity, BMI, presence of metabolic syndrome, and other comorbidities between the two groups were similar. There were no significant differences in GTT, FBG, HOMA-IR, and serum lipids. Patients on acitretin >25 mg daily had lower FBG [4.4 (0.8) versus 4.9 (0.9), P = 0.04] and triglyceride [1.05 (0.33) versus 1.57 (1.03), P = 0.02] compared with doses ≤25 mg. Higher acitretin dose correlated with lower FBG (r = -0.36, P = 0.05) and triglycerides (r = -0.37, P = 0.05) while longer therapy duration correlated with lower total cholesterol (r = -0.37, P = 0.05). HOMA-IR showed inverse correlation with acitretin dose and duration (r = -0.10, P = 0.61 and r = -0.12, P = 0.53, respectively).
CONCLUSION: Acitretin therapy resulted in increased triglyceride. The effect of acitretin on glucose metabolism and insulin resistance maybe dependent on the dose and duration of therapy.
Fulltext Position Statement on Secukinumab in the Management of Plaque Psoriasis: The Malaysian Perspective

Psoriasis is a chronic inflammatory skin disease affecting nearly 10% of dermatologic patients in Malaysia. Treatment options include topical agents and phototherapy as well as nonbiologic and biologic systemic therapy. Mild psoriasis can often be managed with topical agents. However, managing moderate to severe psoriasis is more challenging and may require systemic treatment with nonbiologics or biologics. Despite the availability of several biologics, there are many unmet clinical needs, which may be addressed by secukinumab, an IL-17A inhibitor. This position statement is based on an expert panel discussion and is intended to provide dermatologists an overview of existing options as well as to provide a better understanding of secukinumab and how it can be integrated into current practice. During the discussion, panel members examined current approaches and the role of secukinumab in plaque psoriasis management. Panel members estimated that up to 30% of patients have moderate to severe psoriasis but only 1-2% receive biologics. Highlights from the discussion were that (i) the threshold for biologic use should be lower, in line with international guidelines; (ii) studies have shown that secukinumab has several advantages over other biologics which are greater efficacy, sustained efficacy over time, rapid onset of action, and early evidence of possible disease-modifying potential; and (iii) ideal candidates for secukinumab are all patients of moderate to severe psoriasis, including those with history of treatment failure, difficult-to-treat patterns of psoriasis (nail, scalp, and palmoplantar psoriasis), psoriatic arthritis, and comorbidities and those aiming for clear skin. Panel members recommend that secukinumab be considered first line option among biologic therapies.
