Opportunistic Strongyloides stercoralis infection in lymphoma patients. Report of a case and review of the literature

Cancer (Impact Factor: 4.89). 04/1989; 63(7):1407 - 1411. DOI: 10.1002/1097-0142(19890401)63:7<1407::AID-CNCR2820630729>3.0.CO;2-I

ABSTRACT

Strongyloides stercoralis is an intestinal parasite that may cause fatal opportunistic infections in immunocompromised patients. Herein is reported a patient who developed fatal disseminated strongyloidiasis 6 weeks after the initiation of chemotherapy for a large cell lymphoma of the small intestine. After reviewing the clinical and epidemiologic features of 16 other cases of disseminated strongyloidiasis in patients with malignant lymphomas, the currently available laboratory methods for the diagnosis of this parasite are outlined. Because uncomplicated infections are treatable, candidates for chemotherapy or immunosuppression with a relevant geographic history should be screened for S. stercoralis prior to the initiation of the treatment.

    ABSTRACT: Strongyloides stercoralis is a nematode parasite, which is endemic in tropical and subtropical regions. Infection usually remains asymptomatic, but in immunocompromised hosts severe and life-threatening manifestations such as hyperinfection syndrome and disseminated disease might occur. We retrospectively analyzed the epidemiological and clinical characteristics, including HIV co-infection, microbiological findings, and outcome in 30 patients with strongyloidiasis, who attended in the Infectious Diseases F. J. Muñiz Hospital in Buenos Aires from January 2004 to December 2008. The study included 20 men and 10 women with an average age of 33 years. HIV co-infection was present in 21 patients (70%) with a median CD4 T cell count of 50 cells/mm³ (range 7-355) (average 56 cells/mm³). Among HIV negative patients the following comorbidities were detected: tuberculosis (n = 3) and chronic alcoholism, leprosy treated with corticosteroids, immunosuppressive treatment for psoriasis, and diabetes mellitus (each in one patient). Two patients did not have any predisposing diseases or immunosuppressive treatments. Seventeen patients presented with diarrhea and were classified as chronic intestinal strongyloidiasis (57%), asymptomatic infection with peripheral eosinophilia was diagnosed in 7 (23%), and 6 patients (20%) developed hyperinfection syndrome. Seventeen patients (57%) presented peripheral eosinophilia. Diagnosis was achieved by direct visualization of larvae in feces by Baermann technique (n = 20), by multiple stool smears examinations (n = 2), by combination of both (n = 1), by visualization of the filariform larvae in duodenal fluid and stool (n = 1), and in fecal and bronchoalveolar lavage specimens (n = 6). Overall mortality in this series was 20% (6/30). There was no significant correlation between age and mortality. A significant inverse correlation between the survival rate and CD4 T-cell count as well as eosinophilia was observed. There was also a significant correlation between HIV co-infection and mortality. Twenty-two patients responded favorably to treatment with ivermectin.

    ABSTRACT: Strongyloides stercoralis infection can persist in the host for several decades, and patients with cancer and other clinical conditions who are exposed to immunosuppressive therapy are at risk of developing hyperinfection. This is a case of angioimmunoblastic T-cell lymphoma (AITL) in a patient with lymphadenopathy and bulky neck mass. Severe sepsis and episodes of diarrhea were observed upon the first cycle of cyclophosphamide, doxorubicin, oncovin (vincristine) and prednisone (CHOP) regime chemotherapy preceded by high dose of dexamethasone. There was Klebsiella pneumoniae bacteremia and moderate eosinophilia. Rhabditiform S. stercoralis larvae were observed in the stool, and this was confirmed by real-time PCR. Strongyloides-specific IgG and IgG4 were also positive. The patient was treated with oral albendazole (400mg/day) for 3 days and intravenous tazocin (4.5gm/6 hours) for 5 days; however he succumbed following multi-organ failure. This is likely a case of Strongyloides hyperinfection with secondary bacteremia.
