Cryotherapy is a standard treatment for warts. Tuberculin immunotherapy is a novel therapeutic option. We compared the efficacy and safety of cryotherapy versus tuberculin immunotherapy in a randomized, assessor-blinded study. 15 patients were treated with intralesional tuberculin and 15 patients received cryotherapy every 2 weeks until complete wart resolution or a maximum of six sessions. Wart diameter, total number of warts and adverse effects were documented. Complete clearance of treated warts was achieved in 13(86.7%) and 11(73.3%) of patients with immunotherapy and cryotherapy respectively. Immunotherapy showed greater wart size reduction (51.88 ± 89.36 mm) than cryotherapy (32.99 ± 36.19 mm), (p = 0.46). Immunotherapy resulted in 64% reduction in total number of warts compared to 23.2% with cryotherapy, p

OBJECTIVE: Antibiotics and retinoids have been used for acne vulgaris for decades. Though effective, each has its own drawbacks. Chemical peels have been used for treatment of acne vulgaris with inadequate clinical evidence. We sought to determine the efficacy and safety of Jessner's solution (JS) in comparison with salicylic acid (SA) 30% in the management of acne vulgaris and postacne hyperpigmentation in patients with colored skin.
METHODS: A total of 36 subjects (94.5% Fitzpatick Type IV-V) were recruited in this randomized double-blinded, split-face, controlled trial. Each side of the face was randomly assigned for treatment with either JS or SA. Subjects were treated once fortnightly for a total of three sessions. Lesion counting, Michaelsson acne score (MAS), photographs, and postacne hyperpigmentation index (PAHPI) were used to objectively assess the improvement. Complications were assessed during each visit. Statistical analysis was conducted using SPSS v22.0. Significance was set at P = 0.05.
RESULTS: At the end of therapy, significant reduction in inflammatory, noninflammatory lesions, MAS, and PAHPI scores (P

Hydroxychloroquine (HCQ) is the first-line systemic treatment for cutaneous lupus erythematosus (CLE). Whole blood HCQ concentration (WBHCQ) was found to correlate with CLE severity among Caucasians. However, studies on Asians are scarce. We aim to explore the relationship of WBHCQ with CLE disease activity among multi-racial Malaysians and the factors associated with WBHCQ. A cross-sectional study targeting patients with CLE was conducted from 1 June till 30 November 2019. Disease activity was assessed using Cutaneous Lupus Erythematosus Disease Area and Severity Index - Activity Score (CLASI-AS). Blood was analyzed for WBHCQ concentration using a high-performance liquid chromatography technique. Statistical analysis was done using R studio version 1.2.1335. A total of 88 subjects (male : female, 4.5:1) with a median age of 41 years old were recruited. The median duration CLE was 5 years. The majority had acute cutaneous lupus (n = 45, 51.1%). The median WBHCQ was 946.8 ng/mL. Indians were found to have the highest WBHCQ (median ± interquartile range [IQR], 1515.4 ± 1494.8 ng/mL). Males had a lower WBHCQ (median ± IQR, 733.5 ± 573.8 ng/mL) than females (995.5 ± 925.1 ng/mL). However, no statistically significant association between race and sex with WBHCQ was demonstrable (p = 0.247, p = 0.066). No correlation was demonstrated between WBHCQ and CLASI-AS (r = -0.02, p = 0.851). A positive correlation was found between HCQ dosage (ideal bodyweight) and WBHCQ (r = 0.24, p = 0.027). No other factors were found associated with WBHCQ. Indians and females were observed to have higher WBCHQ; however, no significant correlation was identified. Further study is required to confirm the finding.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a wide range of clinical manifestations and multifactorial etiologies ranging from environmental to genetic. SLE is associated with dysregulated immunological reactions, with increased immune complex formation leading to end-organ damages such as lupus nephritis, cutaneous lupus, and musculoskeletal disorders. Lupus treatment aims to reduce disease activity, prevent organ damage, and improve long-term patient survival and quality of life. Antimalarial, hydroxychloroquine (HCQ) is used as a first-line systemic treatment for lupus. It has shown profound efficacy in lupus and its associated conditions. However, wide variation in terms of clinical response to this drug has been observed among this group of patients. This variability has limited the potential of HCQ to achieve absolute clinical benefits. Several factors, including genetic polymorphisms of cytochrome P450 enzymes, have been stipulated as key entities leading to this inter-individual variation. Thus, there is a need for more studies to understand the role of genetic polymorphisms in CYP450 enzymes in the clinical response to HCQ. Focusing on the role of genetic polymorphism on whole blood HCQ in lupus disorder, this review aims to highlight up-to-date pathophysiology of SLE, the mechanism of action of HCQ, and finally the role of genetic polymorphism of CYP450 enzymes on whole blood HCQ level as well as clinical response in lupus.
