Abstract
JULIA ROMERO, Celia; BADENES GOTERRIS, Ferrán and VEINTIMILLA ESCOT, Alba. Hyperinfection on Strongyloides stercolaris of early appearance after corticosteroid treatment of a nephrotic syndrome. Rev Cubana Med Trop [online]. 2022, vol.74, n.1 Epub May 02, 2022. ISSN 1561-3054.
Strongyloides stercolaris is an endemic threadworm from tropical areas that infects its host through transcutaneous penetration of its filariform larvae. Generally, S. stercolaris infection is asymptomatic. However, in a percentage of immunosuppressed patients, the hyperinfection syndrome may occur, presenting constitutional symptoms, gastrointestinal, pulmonary and, sometimes, central nervous system symptoms. The association between S. stercolaris and glomerular damage is unusual. We report the case of a 42-year-old Bolivian patient, living in Spain, that came to the emergency room due to edema in lower limbs and dyspnea. Symptoms and laboratory test results were compatible with nephrotic syndrome, so she was admitted to Nephrology to receive treatment with intravenous corticosteroids, as well as a renal biopsy. After 10 days of treatment, she presented clinical improvement, so she was discharged waiting the anatomopathological results. Ten days later, she was readmitted due to severe abdominal pain, diarrhea, and persistent dyspnea. The patient was diagnosed with hyperinfection syndrome due to S. stercolaris secondary to the immunosuppressive treatment received. Symptoms resolved with ivermectin and albendazole. Biopsy results revealed findings consistent with minimal change disease secondary to S. stercolaris infection. Although glomerulopathy usually appears between the first and second month after immunosuppressive treatment, in the present study, an early appearance of symptoms was observed compared to the rest of the cases, appearing on day 21 of corticosteroid treatment.
