Strongyloides hyper-infection causing life-threatening gastrointestinal bleeding.

A 55-year old male patient was diagnosed with strongy-loides hyper-infection with stool analysis and intestinal biopsy shortly after his chemotherapy for myeloma. He was commenced on albendazole anthelmintic therapy. After initiation of the treatment he suffered life-threatening gastrointestinal (GI) bleeding. Repeated endoscopies showed diffuse multi-focal intestinal bleeding. The patient required huge amounts of red blood cells and plasma transfusions and correction of haemostasis with recombinant activated factor VII. Abdominal aorto-angiography showed numerous micro-aneurysms ('berry aneurysms') in the superior and inferior mesenteric arteries' territories. While the biopsy taken prior to the treatment with albendazole did not show evidence of vasculitis, the biopsy taken after initiation of therapy revealed leukoclastic aggregations around the vessels. These findings suggest that, in addition to direct destruction of the mucosa, vasculitis could be an important additive factor causing the massive GI bleeding during the anthelmintic treatment. This might result from substances released by the worms that have been killed with anthelmintic therapy. Current guidelines advise steroids to be tapered and stopped in case of systematic parasitic infections as they might reduce immunity and precipitate parasitic hyper-infection. In our opinion, steroid therapy might be of value in the management of strongyloides hyper-infection related vasculitis, in addition to the anthelmintic treatment. Indeed, steroid therapy of vasculitis with other means of supportive care resulted in cessation of the bleeding and recovery of the patient.

Electroencephalography, Doppler vascular scanning, and single photon emission computed tomography in a child with hydranencephaly and intractable seizures.

In a child with hydranencephaly and refractory seizures, the electroencephalogram showed a flat isoelectric pattern with no significant slow waves or epileptiform activity; cranial computed tomography, magnetic resonance imaging, Doppler vascular scanning, and single photon emission computed tomography (SPECT) were done to define the pathogenesis of the seizures. The investigations were suggestive of a lack of significant cortical, subcortical, or thalamic structures with hypoplasia of the vermis and cerebellum. SPECT showed little activity in the base of the brain and cerebellum. The cause of the seizures remained unclear in spite of the investigations.

The clinical course and sequel of the life-threatening gastrointestinal (GI) bleeding during the treatment of strongyloides helmintic hyperinfection induced by immunosuppression in a patient with multiple myeloma is presented. A 55-year old male patient was diagnosed with strongyloides infection with stool analysis and intestinal biopsy shortly after his combined chemotherapy for myeloma. He was commenced on albendazole anthelmintic therapy. However, after initiation of the treatment he suffered life-threatening GI bleeding. Repeated endoscopies, including intraoperative enteroscopy, concluded to diffuse multifocal intestinal bleeding. The patient required huge amounts of red blood cells and plasma transfusions and correction of haemostasis with recombinant activated factor VII. Abdominal aorto-angiography showed numerous microaneurysms ("berry aneurysms") in the superior and inferior mesenteric arteries' territories. While the biopsy taken prior to the treatment with albendazole did not show evidence of vasculitis, the biopsy taken after initiation of therapy revealed leukoclastic aggregations around the vessels which was also consistent with vasculitis. These findings suggest that--in addition to direct destruction of the mucosa-vasculitis could be an important additive factor to the massive GI bleeding during the anthelmintic treatment. This might result from substances released by the worms that have been killed with anthelmintic drugs. Current guidelines advise steroids to be tapered and stopped in case of systematic parasitic infections as they reduce immunity and precipitate parasitic hyperinfection. In our pinion, steroid therapy might be of value in the management of strongyloides hyperinfection related vasculitis--in addition to the specific anthelmintic treatment. Indeed, steroid therapy of vasculitis with other means of supportive care yielded in sequel of the bleeding and in recovery of the patient.
