Background: Strongyloides stercoralis infection is a neglected tropical disease in endemic areas such as Peru, with an overall frequency of 6.6%. Four clinical syndromes can be distinguished: acute (AS), chronic (CS), hyperinfection (HS) and disseminated strongyloidiasis (DS). Objective: To describe the clinical and epidemiological characteristics of patients diagnosed with strongyloidiasis. Material and methods: 27 clinical charts of patients with estrongioloidiasis admitted from July 2014 to August 2015 at the Hospital Regional Lambayeque, from Peru, were reviewed. Results: The median age was 41 years (Interquartile range: 2 to 84) and 74% (20/27) were males. There were 10 (37.04%) cases of CS and 10 cases (37.04%) of HS. Of the total, 63% presented eosinophilia, 85.2% anemia and 85.1% diarrhea; 59.3% were some type of immunocompromise and 18.5% died. Conclusions: The majority of patients with strongyloidiasis in this study presented CS and HS, eosinophilia, anemia, diarrhea and some type of immunocompromise. Also, the high frequency of severe strongyloidiasis in patients with immunocompromise reveals the need for a coproparasitological screening with specific methods (Baerman and agar culture) to detect and treat previously chronic infection.
