Is There a Role for Opportunistic Infection Prophylaxis in Pemphigus? An Expert Survey

Abstract

Background

Opportunistic infections (OIs) are a dreaded adverse effect of immunosuppressive therapy, leading to the use of opportunistic infection prophylaxis (OIP) in many immunosuppressed conditions. However, guidelines for OIP in pemphigus are lacking.

Objective

Our objective was to evaluate the approach of leading pemphigus experts towards OIP.

Methods

We conducted an online survey of OIP trends.

Results

The survey was completed by 33 experts. Prior to initiation of immunosuppressive therapy, 75% routinely screened for hepatitis viruses, and at least half screened for HIV or tuberculosis. Most experts (76%) prescribed OIP but to <10% of their patients, and the most frequent drugs of choice were sulfamethoxazole/trimethoprim and acyclovir. Most experts agreed that treatment with three or more immunosuppressive agents or a previous history of OIs would lead to the use of OIP that was then discontinued with cessation of immunosuppression. The arguments against OIP were the lack of evidence for its necessity and concern about side effects or emergence of resistant pathogens. The surveyed experts treated patients with severe disease in a tertiary care setting, which may have led to an overestimation of the use of OIP. Infectious disease specialists were not included.

Conclusion

Substantial disparities exist in approaches to OIP for patients with pemphigus, including the decision to treat, type of treatment, and risk stratification among pemphigus experts.
