    Abstract:
    Strongyloidiasis is a gastrointestinal parasitic infection caused by percutaneous infection with Strongyloides stercoralis, which is mainly distributed in the tropics and subtropics worldwide. Digestive symptoms like diarrhea and abdominal pain are the main manifestation, but serious infections such as bacterial pneumonia, purulent meningitis and sepsis also occur in immunocompromised individuals. Herein, we present a rare case of a type II diabetes mellitus (T2DM) patient presented with gastrointestinal hemorrhage and sepsis caused by concomitant Strongyloides stercoralis and cytomegalovirus (CMV) infection. This 51-year-old male patient presented to the hospital with vomiting, diarrhea, dyspnea, palpitation and weakness. Examination revealed skin soft-tissue infection with T2DM, and upper endoscopy revealed gastric mucosal erosion and hemorrhage. Radiology revealed bilateral diffuse interstitial infiltrates and thickened walls of the colon. Importantly, stool and vomitus examination showed numerous larvae of Strongyloides stercoralis. Then the diagnosis of Strongyloides hyperinfection syndrome was made. But antibiotics and albendazole treatment did not improve the patient's symptoms of gastrointestinal bleeding and sepsis. Subsequently, other pathogens were screened by sequence and a positive CMV gene was found in the peripheral blood. Thus, antibiotics, albendazole and ganciclovir were all used which ultimately resolved the infection in this patient. Therefore, this case indicated CMV could also by co-infected with Strongyloides stercoralis in the immunocompromised patient, which remind us that an CMV test should also be performed when encountered in severe strongyloidiasis infection, which could improve the prognosis of the patient.
