ABSTRACT
@#INTRODUCTION: Linear IgA bullous disease (LABD) is a rare autoimmune blistering disease characterized by subepithelial bullae and linear IgA deposition along the basement membrane zone of the epidermis. Lesions present as pruritic papulovesicles and tense bullae which may coalesce forming annular or polycyclic urticarial plaques with blistering on the edge of the lesions forming the classic “string of pearls” sign. Lesions may affect the face, trunk, and extensor extremities. Incidence rates range from 0.5 to 2.3 cases per million individuals per year. Due to its rare occurrence, there are only a fewdocumented reports on cases of LABD, particularly in the Filipino population. CASE REPORT: A 33 year-old Filipino female consulted because of a 3-week history of severely pruritic vesicles and crusts on the face, trunk, and arms. Patient noted no gastrointestinal symptoms on consultation. Skin punch biopsy revealed subepidermal blisters with collection of neutrophils at the dermal papillae. Direct immunofluorescence showed strong (+2) deposits of linear IgA at the dermo- epidermal junction in perilesional skin thus validating the diagnosis. The patient’s serum was negative for IgA anti-tissue transglutaminase and IgA antiendomysial antibodies. Patient was treated with topical corticosteroids and Dapsone 50 mgs OD with remarkable improvement. CONCLUSION: Linear IgA bullous disease has very few reported cases especially in the Philippine setting. Dapsone is considered the first-line treatment. The disease may persist for a decade or longer, and relapses may occur. Careful history-taking accompanied by the histological, immunofluorescence, and serological findings must be done to ensure proper treatment and good prognosis.

Background@#Superficial pyoderma is an infection most commonly caused by Staphyloccoccus aureus. The drug of choice is 2% mupirocin cream. However, high cost and emerging drug resistance affect compliance and overall cure. Tinospora rumphii has demonstrated antibacterial activity in vivo rendering it a potential cost-effective alternative treatment.@*Objectives@#To determine the safety and efficacy of 25% T. rumphii cream versus 2% mupirocin cream in the treatment of superficial pyodermas caused by S. aureus.@*Methods@#A randomized, double-blind, controlled study of 60 patients with superficial pyodermas caused by S aureus, aged 18-60, were given either 25% T. rumphii or 2% mupirocin cream for two weeks. Bactericidal activity, erythema, edema, induration and size of lesion were evaluated at baseline, days 3, 7, and 14. Participants Global Assessment (PGA) score and adverse events were noted. Statistical analysis was done using Mann-Whitney U and Pearson Chi square test. RESULTS: Fifty-one subjects (85%) completed the trial. There were no statistically significant differences between the two treatment groups for bactericial activity against Staphylococcus aureus (p=0.687) at day 14, for erythema (p=0.923, 0.5335, 0.3726, 0.6949), edema (p=0.0972, 0.5967, 0.2052, 0.2783), induration (p=0.0855, 0.3113, 0.281, 0.3161), and size of lesions (p=0.7262, 0.169, 0.15, 0.3988) at baseline, days 3, 7 and 14. There was no significant difference in PGA score (p=0.3086, 0.3483, 0.2234) at Days 3, 7 and 14 in both groups. No adverse events were noted.@*Conclusion@#Twenty five percent T. rumphii cream is equally safe and effective as 2% mupirocin cream for treatment of superficial pyodermas caused by S. aureus.
