ENDEMIC ZONES: Strongyloidiasis is an intestinal parasitosis which is frequently found in tropical and subtropical regions. RISK: The "autoinfection" cycle during this helminthiasis explains why the infection can be perpetuated without further exposure to exogenous, infective larvae. Hyperinfection may occur by dissemination of Strongyloides stercoralis in immuno-compromised patients, particularly those under corticotherapy. DISSEMINATATED STRONGYLOIDIASIS: Disseminated strongyloidiasis is characterized by severe gastrointestinal and respiratory tract involvement, meningitis, skin rash, or Gram-negative bacteremia. Since disseminated stronglyoidiasis is fatal in 80% of cases it is imperative to diagnose and treat this condition before long-term corticotherapy. Ivermectin is currently recommended because it is effective and well tolerated.

Individuals with hematologic malignancy have increased risk of latent tuberculosis infection (LTBI) reactivation and (SS) dissemination. However, screening prior to chemotherapy or corticosteroids is not routine. We conducted a LTBI and SS screening intervention amongst patients with hematologic malignancies.

The use of immunosuppressants such as corticosteroids and Baricitinib for treating COVID-19 pneumonia can be responsible for patients' immunosuppression and cause Strongyloides hyperinfection syndrome. The chance increases when the patient belongs to countries or regions where chronic infection with Strongyloides is more prevalent.

Cytomegalovirus (CMV) infection is an opportunistic disease in immunocompromised patients that may appear without symptoms, with constitutional symptoms, or as a tissue-invasive disease. infection often manifests with non-specific symptoms; however, it can lead to severe malabsorption and extraintestinal dissemination by accelerated autoinfection. The coinfection of CMV and has rarely been reported, particularly with solely severe gastrointestinal bleeding.
