Helminth infection and control

Strongyloidiasis is an intestinal parasitic infection that is particularly relevant in immunosuppressed patients because it can cause severe disseminated disease. This review discusses the recent advances in the diagnosis of strongyloidiasis. We suggest clinical and epidemiologic criteria for the diagnosis and screening of strongyloidiasis, taking into account different epidemiologic contexts. The state of the art of the diagnosis of strongyloidiasis is discussed including parasitologic methods that are commonly used despite having low sensitivity; serology, which has demonstrated better sensitivity (with some exceptions such as travelers or immunosuppressed patients), and molecular biology methods, which have virtually 100 % specificity. Finally, we discuss different strategies to follow up patients after treatment, highlighting the importance of having accurate and reliable follow-up markers when assessing treatment efficacy both in a clinical and research context.
