Co-infection with Strongyloides stercoralis hyperinfection syndrome and Klebsiella in a nephrotic syndrome patient: A case report.

rationalePatients with chronic Strongyloides stercoralis infection are usually asymptomatic; therefore, their condition is easily overlooked. In immunosuppressed patients, mortality is high because of disseminated infection and hyperinfection. This report describes a fatal S stercoralis hyperinfection in a patient with nephrotic syndrome after treatment with steroids. PATIENT CONCERNS: A 70-year-old male presented with a history of progressive edema, skin infection, persistent fever, cough, intermittent abdominal pain, and progressive respiratory failure after steroid treatment. DIAGNOSIS: Nephrotic syndrome; cellulitis; S stercoralis hyperinfection; Klebsiella pneumonia.

interventionsDuring the first hospital admission, the patient was administered full-dose glucocorticoid and antibiotic therapy after suffering from cellulitis. During the second admission, he was diagnosed and treated for normal digestive discomfort and a bacterial infection. The patient had progressive respiratory failure and was placed on a ventilator. He was immediately treated with albendazole when S stercoralis was found in samples of his sputum and feces. OUTCOMES: The patient died despite treatment with albendazole and antibiotic therapy. LESSONS: It is essential to consider the possibility of S stercoralis infection in immunosuppressed patients with nephrotic syndrome. Given the lack of classic manifestations and high mortality rate of advanced disease, continuous monitoring, early diagnosis, and proper treatment are imperative.
