Background:
Lipid lowering drugs (LLDs) are widely used. However, reports on its adverse cutaneous drug reactions (ACDRs) are
scarce.
Objectives:
The study objective was to review the patterns of LLD induced ACDRs.
Methods:
We reviewed all LLDs induced ACDRs reported to MADRAC (Malaysian Adverse Drug Reaction Advisory Committee) from
January 2005 till December 2009.
Results:
LLD induced ACDRs (124 patients) comprised of 2.07% of all ACDRs reported during the study period. Statins were
responsible for most cases (81.5%), followed by fibrates (15.8%), selective cholesterol-absorption inhibitors (1.4%) and
combination therapies (statin/selective cholesterol-absorption inhibitors and selective prostaglandin-2 receptor inhibitor/
niacin) in 1.4%. Majority were due to lovastatin (42.5%), simvastatin (28.1%) and gemfibrozil (8.9%). The three commonest
ACDRs reported with statins usage were non-specific dermatitis (45.0%), pruritus/stinging (25.0%) and urticaria/angioedema
(10.0%) while fibrates caused non-specific dermatitis (52.2%), urticaria/angioedema (13.0%) and photodermatitis (9.7%).
There was no reported case of photodermatitis associated with statin usage. Interestingly, statins were the offending
drugs resulting in all the five cases of vesiculobullous eruptions, two cases of Stevens-Johnson syndrome and one case of
dermatomyositis. No mortalities were reported to be associated with LLD induced ACDRs.
Conclusions:
LLD induced ACDRs were not uncommon. Statins were the main putative drugs implicated in those reactions. Spectrum
of ACDRs differed between statin and fibrate although non-specific dermatitis remained the main ACDRs in both classes.
The unavailability of guided and classified ACDRs reporting accounted for the large number of non-specific dermatitis.
Although most LLD induced ACDRs were mild, statins were reported to cause severe ACDRs.

Bullous pemphigoid (BP) has a recognized association with solid organ tumors, but is relatively rare in hematological malignancies. We report a 67-year-old male who developed BP after being diagnosed with myelodysplastic syndrome and refractory anemia with excess of blast (RAEB). Skin biopsy elucidated sub-epidermal bulla using direct immunofluorescence, revealing linear C3 and IgG deposits along the basement membrane. His BP was recalcitrant to the conventional treatment and only responded to a combination of high dose oral prednisolone and azathioprine. The relative refractory nature of his condition and concurrent RAEB supports a paraneoplastic nature.

Introduction: Acne vulgaris is a chronic inflammatory dermatosis caused by Propionibacterium acnes. Clinicians are constantly attempting to discover the best antibiotic regimes in treating acne vulgaris. This study compares two regimens in terms of efficacy, tolerability, compliance and recurrence rate to make recommendation on which is the best regime. Methods: An open-labelled prospective randomized investigator-blinded interventional study was carried on moderate acne vulgaris patients. Patients were assigned to treatment arm at enrolment followed by follow-up and maintenance visits. Demographic data were collected at enrolment and questionnaire enquiring acne condition, general health and quality of life impairment were filled at every visit followed by blinded dermatologist assessment. Antibiotic tablets were provided based on assigned arm until follow-up 3. Results: 26 mild acne vulgaris patients aged 17 to 29 years were recruited. Physician assessment based on GAGS and photo assessment analysis showed an overall significant change (p<0.05) with decreasing trend indicating that the treatment is statistically effective. However, no significant differences (p>0.05) were found between regimens. Similarly, patient self-perceived assessment and CADI assessment also showed overall significant changes (p<0.05) with increasing trend indicating improvement in acne condition but no significant differences (p<0.05) between regimens. Conclusion: Neither regimen were significantly more efficacious than another. In view of cost, oral azithromycin 500mg daily for consecutive 4 days monthly is suggested as a better option.
