Hyperinfection syndrome should be considered a potential medical emergency. Thus, treatment should be started immediately if this is being considered. Strongyloides stercoralis Hyperinfection remain quiescent indefinitely, immunosuppression can lead to the hyperinfection syndrome, which is. Whereas in chronic strongyloidiasis and in hyperinfection syndrome the larvae are limited to the GI tract and the lungs, in disseminated.

However, Kerepesi et al. Case report A 77 year old male veteran with past medical history significant for chronic obstructive pulmonary disease, coronary artery disease status post coronary artery bypass graft, dyslipidemia, hypertension, and gastro esophageal reflux disease was found to have an incidental eosinophilia with A 77 year old male veteran with past medical history significant for chronic obstructive pulmonary disease, coronary artery disease status post coronary artery bypass graft, dyslipidemia, hypertension, and gastro esophageal reflux disease was found to have an incidental eosinophilia with This can also lead to polymicrobial bacteremia, gram-negative bacillary meningitis, pneumonitis, and alveolar hemorrhage.
Choi S, Reddy P. Within the intestinal lumen, the eggs hatch into noninfective rhabditiform larvae, which are excreted, along with stool, into the environment ie, soil. IL-3 Interleukin-3 has been shown in multiple previous studies as a potent mast cell synthesis stimulator.
Although multiple agents have been implicated in increasing the risk of hyperinfection syndrome, corticosteroids administration carries the greatest risk; interestingly, disseminated Strongyloides infection has occurred within a week of corticosteroid initiation [ 23 ]. Chronic strongyloidiasis most frequently causes asymptomatic infection in immunocompetent individuals. Of all the mentioned methods, multiple studies have shown detection of strongyloides larvae in stool specimens is more effective and accurate with agar plate culture technique [ 473 – 75 ].
Chronic infection and malnutrition also predispose to systemic strongyloidiasis [ 19 ]. Clin Exp Nephrol ; Other manifestations including disseminated infection Even though, most cases of strongyloidiasis are asymptomatic or present with mild symptoms, fatal disseminated infection with involvement of multiple organ systems other than the respiratory and gastrointestinal systems as in hyperinfection syndrome could also occur especially in patients with immunosuppression from systemic steroids [ 14 ].
Although albendazole, mechanical ventilator support, fluid resuscitation, vasopressor support, extracorporeal membrane oxygenation, hydrocortisone, and broadspectrum antimicrobials were actively used, the patient eventually died. Due to the asymptomatic nature of intestinal strongyloidiasis, and the risk for hyperinfection, screening of the population in endemic areas especially before considering immunosuppressive therapy is important.
Intestinal strongyloidiasis and hyperinfection syndrome
Fatal Strongyloides stercoralis infection in a young woman with lupus glomerulonephritis. Travel-related schistosomiasis, strongyloidiasis, filariasis, and toxocariasis: Occasionally this may also present as a pruritic, erythematous, morbiliform eruption [ 15 ], or as an intensely itching prurigo [ 23 ]. Dissemination of Strongyloides stercoralis as an immune restoration phenomenon in an HIVinfected man on antiretroviral therapy. Centers for Disease Control and Prevention; Strongyloides stercoralis in the Immunocompromised Population.
Although Strongyloides often causes chronic and clinically asymptomatic infection, parasite number can increase substantially in those who are immunocompromised, leading to hyperinfection, dissemination, and death if unrecognized.
As no human studies are available indicating the importance of IL-4, and with the exact role of IL-4 in helminth infection being unknown, it would be premature to consider IL-4 as an important factor in the defense against strongyloidiasis [ 91 ].
He was discharged home on D83 on valganciclovir, cotrimoxazole, and prednisolone. To the best of our knowledge, this is the first case report of Strongyloides hyperinfection with concurrent CMV infection and Gram-negative sepsis in a Saudi patient.

His computed tomographic scan of the abdomen revealed peripancreatic, peritoneal effusion, ascites, and the stomach diffuse edema. Acknowledgements The authors would like to express their appreciation hyperindection Mrs. Studies of the use of albendazole in children as young as one year old suggest that its hylerinfection is safe. He was given a preliminary diagnosis of septic shock from abdominal source, and acute respiratory failure. J Nephrol ; Severe infection with Strongyloides has not been observed frequently with HIV-infected patients [ 29 ].
Endoscopic view of the duodenal bulb in a patient with Strongyloides hyperinfection syndrome.
Intestinal strongyloidiasis and hyperinfection syndrome
The role of B cells in immunity against larval Strongyloides stercoralis in mice. Studies with animal models and Strongyloides ratti showed the important role played by goblet cells in the expulsion of the parasite from the GI tract [ 81 ]. Strongyloidiasis among patients with chronic kidney disease is rarely reported.
More on this topic Strongyloidiasis: Also rare, but documented, are endoscopic exams revealing pathology similar to pseudopolyposis. Thus, parasites can remain in the human body for the remainder of the host’s life. Mucosal immunity against parasitic gastrointestinal nematodes. The authors declare that there are no competing interests regarding the publication of this paper. His level of consciousness was reduced, with ecchymosis in large area of trunk limbs.
Recently, there has been a change in the treatment of strongyloidiasis with more studies showing ivermectin as the drug of choice. An estimated million people worldwide are infected with S. It affects specific patients with acquired immunodeficiencies such as HTLV-1 or iatrogenically by immunosuppressive agents. Background In United States, strongyloidiasis is the most important nematode infection in humans with a tendency towards chronic persistent infection and with special characteristic features of autoinfection, hyperinfection involving pulmonary and gastrointestinal systems, and disseminated infection involving other organs [ 1 – 4 ].
Articles from Clinical and Molecular Allergy: There is increasing evidence that IgE mediated activation of accessory cells can play an important role in the resistance against parasitic infection [ 82 ]. The hyperinfection syndrome happens from the enormous multiplication and migration of infective larvae especially in an immunosuppressed state.
The following are signs and symptoms that can be seen with hyperinfection syndrome and disseminated strongyloidiasis:. The larvae mature into adult worms, mate and release eggs in the gastrointestinal tract. Infect Dis Clin North Am.
