Inflammatory Syndrome

Parasitic infections such as Strongyloides stercoralis and HIV have been reported to coexist, particularly in resource-limited settings such as India. In an immunocompromised host, S. stercoralis can progress to strongyloidiasis hyperinfection syndrome (SHS). However, SHS is not common in patients with advanced HIV disease. Immune reconstitution inflammatory syndrome (IRIS) developing after initiation of antiretroviral therapy (ART) can target multiple pathogens including S. stercoralis. The authors present here a 46-year-old HIV-infected female who was recently diagnosed with HIV-1 infection, started ART, and developed SHS. Her upper GI endoscopy revealed severe gastroduodenitis, and X-ray chest showed extensive bilateral pneumonitis. We could identify S. stercoralis in induced sputum and duodenal biopsy. We could also identify gut inflammation to restrict invading parasites. After receiving antihelminthic therapy, she showed improvement, a course of events that fit the diagnosis of unmasking S. stercoralis IRIS.

And Control

SUMMARYThe majority of the 30–100 million people infected withStrongyloides stercoralis, a soil transmitted intestinal nematode, have subclinical (or asymptomatic) infections. These infections are commonly chronic and longstanding because of the autoinfective process associated with its unique life cycle. A change in immune status can increase parasite numbers, leading to hyperinfection syndrome, dissemination, and death if unrecognized. Corticosteroid use and HTLV-1 infection are most commonly associated with the hyperinfection syndrome.Strongyloidesadult parasites reside in the small intestine and induce immune responses both local and systemic that remain poorly characterized. Definitive diagnosis ofS. stercoralisinfection is based on stool examinations for larvae, but newer diagnostics – including new immunoassays and molecular tests – will assume primacy in the next few years. Although good treatment options exist for infection and control of this infection might be possible,S. stercoralisremains largely neglected.

We report a case ofStrongyloides stercoralishyperinfection syndrome with central nervous system involvement, in a patient with late human immunodeficiency virus (HIV) infection starting antiretroviral therapy, in whomStrongyloides stercoralislarvae andCryptococcus neoformanswere isolated antemortem from cerebrospinal fluid. Our patient was not from an endemic region for the parasite, so strongyloidiasis was not originally suspected. For this reason, we conclude thatStrongyloides stercoralisinfection should be suspected in HIV-infected patients starting antiretroviral therapy in order to avoid potential fatal outcomes.

SummaryStrongyloidiasis is a parasitic disease that may progress to a disseminated form, called hyperinfection syndrome, in patients with immunosuppression. The hyperinfection syndrome is caused by the wide multiplication and migration of infective larvae, with characteristic gastrointestinal and/or pulmonary involvement. This disease may pose a diagnostic challenge, as it presents with nonspecific findings on endoscopy.

To Receive

Ivermectin, an antiparasitic agent, is not recommended for prophylaxis or treatment of coronavirus disease 2019 (COVID-19). Inappropriate use of ivermectin for treatment of COVID-19 may make it less available for patients with serious parasitic infections who could benefit from its use and worsen the current shortage of ivermectin in Canada. However, patients with COVID-19 who are candidates to receive immunomodulatory therapies (e.g. corticosteroids and interleukin-6 inhibitors) may be at risk of hyperinfection syndrome and disseminated disease from Strongyloides stercoralis. These complications can be severe and even fatal. It is important to recognize and screen patients who may be at risk of strongyloidiasis, as these patients may require treatment with ivermectin to avoid the potential for a hyperinfection syndrome and disseminated disease, which is frequently deadly. Clinicians should follow evidence-based recommendations to screen and treat for Strongyloides infection in patients with COVID-19 who are under consideration to receive specific COVID-19 therapies that alter immune response and may lead to hyperinfection syndrome or disseminated disease.

Strongyloidiasis is caused by the nematode Strongyloides stercoralis which has the unique ability to reproduce and complete its entire life cycle within the human host through its autoinfection cycle. Diagnosis of this infection is important because of its potential to cause fatal hyperinfection syndrome or disseminated infections in those with defective cellular immunity. Parasitological methods based on faecal microscopy and culture often fail to detect low-intensity infections. A multiplex polymerase chain reaction (PCR) assay was developed for the detection of S. stercoralis, Ascaris lumbricoides, and Enterobius vermicularis by designing primers specific for the ITS1 region of ribosomal DNA of S. stercoralis and A. lumbricoides and 18S region of rRNA of E. vermicularis. A 61-year-old patient presented with chronic gastrointestinal and respiratory symptoms and weight loss with a stool microscopy positive for helminth larvae. Stool cultures with the Harada–Mori technique yielded L3 larvae which were identified as S. stercoralis based on morphology. The multiplex PCR performed on DNA extracted from stool elicited the expected band at 129 bp on gel electrophoresis of the PCR yield providing molecular evidence of intestinal strongyloidiasis. The patient’s gastrointestinal symptoms improved with a six-day course of albendazole (400 mg twice daily). Negative posttreatment stool microscopy, culture, and PCR confirmed successful clearance of infection. Molecular-based PCR assay is a promising tool to diagnose and assess the therapeutic efficacy of anthelmintics in intestinal helminthiases such as strongyloidiasis.
