Helminth seropositivity in allergic bronchopulmonary aspergillosis: Co-exposure, misdiagnosis, or cross-reactivity?

Allergic broncho-pulmonary aspergillosis (ABPA) shares clinical and immunologic features with helminth infections. We investigated helminth seropositivity among ABPA patients in a retrospective cross-sectional study. Our findings highlight the need for parasitic evaluation in ABPA patients in helminth-endemic regions, particularly with incomplete treatment response or atypical features.
