Abstract
Objectives Pemphigus, a group of autoimmune bullous diseases, can be fatal, resulting from overwhelming opportunistic infection of lesions secondary to cutaneous bacterial infections. This study aimed to look into the cutaneous bacterial infection profile of pemphigus patients as timely identification and appropriate treatment can play a major role in reducing mortality. Materials and Methods Pus samples/swabs received from patients with pemphigus over a 2-year period from July 2018 to June 2020 were subjected to standard microbiological culture techniques and susceptibility testing. The frequency of isolation and susceptibility profile of the different bacterial pathogens toward various antimicrobial agents were interpreted and analyzed as per the Clinical and Laboratory Standards Institute's guidelines. Results Samples from 315 patients were received during the study period comprising of 203 (64.4%) males and 112 (35.5%) females. Of 211 samples which were culture-positive, a total of 245 bacterial isolates were obtained, comprising of 158 Gram-positive cocci and 87 Gram-negative bacilli. Staphylococcus aureus (138, 56.3%) was the most common isolate followed by Pseudomonas aeruginosa (41, 16.7%) and Escherichia coli (16, 6.5%). Methicillin resistance was observed in 24.6% Staphylococcus aureus isolates and carbapenem resistance in 9.5 to 14.6% Gram-negative bacilli. Conclusions Study findings emphasize the need for continuous monitoring of cutaneous pemphigus lesions for appropriate choice of antimicrobial therapy.
