“…Isolated cases report that strongyloidiasis is associated with nodular lesions in biliary ducts and bronchi, the former resulting in obstructive jaundice and the latter resulting in asthma-like symptoms secondary to an obstructive lung pattern [19, 20]. Another case report described biliary obstruction resulting from papillary stenosis caused by S. stercoralis [21].…”

Strongyloidiasis is an intestinal infection caused by the parasitic nematodes of the Strongyloides species, most commonly Strongyloides stercoralis. We report a case of a 66-year-old immigrant male from Haiti who presented with complaints of diarrhea and an unintentional 80-lb weight loss over the past 5 years. Stool examination was positive for strongyloidiasis. Following albendazole therapy, esophagogastroduodenoscopy (EGD) showed a unique ampullary lesion. Histopathology of the ampullary lesion showed reactive epithelium with Strongyloides larva. In addition, endoscopic ultrasound (EUS) detected a large pancreatic cyst. Both these findings were absent on EGD 5 years previously, prior to the onset of his symptoms. This paper documents a rare case of an ampullary lesion and pancreatic cyst secondary to hepatobiliary strongyloidiasis in a non-Human Immunodeficiency Virus (HIV) patient. We review the epidemiology, life cycle, clinical presentation and treatment of strongyloidiasis.

Strongyloides stercoralis infection after the use of emergency corticosteroids: a case report on hyperinfection syndrome

et al. 2019

View full text Add to dashboard Cite

Background In clinical practice, identification of a case of severe asthma exacerbation prompts initiation of corticosteroids. However, not all that wheezes is asthma. Case presentation A 61-year-old man from the Peruvian Amazon presented with progressive dyspnea, abdominal pain, and cough for the past week. His medical history was remarkable for asthma since childhood; he was treated with beta-agonists, ipratropium, and orally administered corticosteroids. On evaluation, he was febrile and ill-appearing. His chest examination revealed diffuse wheezing and bilateral crackles. He was diagnosed as having community-acquired pneumonia and asthma exacerbation and was started on empiric antibiotics, nebulized beta-agonists, and orally administered corticosteroids. His clinical status continued deteriorating and he became critically ill despite broad-spectrum antibiotics and antifungals. Considering the epidemiological background of our patient, bronchoalveolar and fecal samples were obtained to investigate soil-transmitted helminths. Larvae of Strongyloides stercoralis were found in both specimens. Ivermectin was initiated and corticosteroids were discontinued. He experienced remarkable improvement of clinical condition over the next weeks. The literature on this topic was reviewed. Conclusion Cases of severe asthma exacerbation warrant careful evaluation before the initiation of corticosteroids, especially in patients at risk for parasitic infections. A high index of suspicion is critical. Alternative etiologies of respiratory decompensation should be considered in patients who fail to improve with broad-spectrum antibiotics and antifungals.

Comparative analysis of a chemotherapy effect on the cuticular surface of Wuchereria bancrofti adult worms in vivo

et al. 2007

Wuchereria bancrofti is the main species responsible for human lymphatic filariasis and remains a major public health problem in tropical countries around the world. Diethylcarbamazine (DEC) has been used for decades in control programs as an effective microfilaricide, although its efficacy in killing adult worms is only around 50% and its direct mode of action is unclear. Recently, in an attempt to control and eliminate lymphatic filariasis, WHO has recommended albendazole (ALB), a broad-spectrum anthelminthic combined with DEC or ivermectin for mass treatment. Some studies have shown that DEC alone blocks oogenesis, fertilization in adult worms, and loss of the microfilarial sheath of several filarial species, whereas ALB is thought to target nematode tubulin. So far, the direct effect of ALB in combination with DEC has not been described in W. bancrofti adult worms. Therefore, the purpose of this study is to investigate by scanning electron microscopy if DEC coadministered with ALB can induce in vivo morphological alterations of the W. bancrofti adult worm surface obtained from a patient in whom the adult worm remained alive, checked serially by ultrasonography for 2 months after antifilarial treatment. Our analysis demonstrates that worms presented morphologic alterations in some regions suggesting cuticular surface damage. On the other hand, adult worms that were recovered from a patient treated with DEC alone after a single dose did not show such any abnormalities.
