The effect of albendazole treatment on non-seizure outcomes in patients with symptomatic neurocysticercosis.

Background: There is little information about the impact of anthelminthic treatment on clinical symptoms other than seizures in neurocysticercosis (NC). We investigated the effect of albendazole on non-seizure symptoms experienced by patients with NC. Methods: Data are from a randomized controlled trial comparing albendazole plus prednisone with placebo plus prednisone for treatment of NC among 173 patients with active or transitional NC cysts and new-onset symptoms. We performed negative binomial regression to examine the number of follow-up visits when a symptom was reported, logistic regression to examine the probability of experiencing the symptom and Cox proportional hazards models to examine the time to first reporting the symptom. Results: Eighty-five percent of patients reported at least one non-seizure symptom at baseline. Those treated with albendazole had significantly lower odds of memory loss and/or confusion during months 1-24 (odds ratio [OR] 0.42, p=0.037) and significantly increased odds of anxiety and/or depression during months 1-12 (OR 1.87, p=0.049). No treatment difference existed in experiencing symptoms in general or in experiencing headaches, limb weakness or gait disturbances, vomiting, nausea and/or stomach pain or visual disturbances over the follow-up period. Conclusions: While the prevalence of non-seizure symptoms was high, albendazole treatment was associated with only two significant differences in the non-seizure symptoms over follow-up. Further research is needed to identify strategies to reduce the long-term symptom burden in patients with NC.

Parasitic myositis in tropical Australia.

Three patients with Australian parasitic myositis caused by the muspiceoid nematode Haycocknema perplexum are described. Treatment with albendazole led to a slow and incomplete recovery, but treatment with steroids caused life-threatening deterioration.

Diagnosis of Strongyloides stercoralis in a peritoneal effusion from an HIV-seropositive man. A case report.

BACKGROUND: Strongyloides stercoralis, a nematode parasite in humans with free-living and autoinfective cycles, is often an asymptomatic infection of the upper small intestine. If the host becomes immunocompromised, autoinfection may increase the intestinal worm burden and lead to disseminated strongyloidiasis. The parthenogenetic adult female larvae can remain embedded in the mucosa of the small intestine for years, producing eggs that develop into either rhabditiform, noninfective larvae or filariform, infective larvae. Manifestations of dissemination occur when the filariform larvae penetrate the intestinal wall and migrate into the blood. Pulmonary involvement is common, and the central nervous system may be affected. Blood eosinophilia is typical, and gram-negative sepsis from enteric bacteria may occur. Much less commonly described is invasion of the peritoneal cavity with peritoneal effusion. CASE: A 49-year-old man who came to the United States from Liberia 4 years earlier presented with sudden onset of severe abdominal distention, generalized weakness and marked pedal edema. Diagnostic paracentesis showed numerous filariform larvae of S stercoralis. Stool examination confirmed the presence of both rhabditiform and filariform larvae. Subsequently the patient was found to be HIV seropositive, with a CD4 lymphocyte count of 59. CONCLUSION: Early detection of S stercoralis may alter the often-fatal course of infection. The present case is the second reported one in the English-language literature of the diagnosis of S stercoralis in ascitic fluid.

A viable residual spinal hydatid cyst cured with albendazole. Case report.

Spinal hydatid disease is a rare entity that frequently yields to severe, acute-onset neurological deficits. Although the gold standard treatment is total surgical removal of the cysts without inducing any spillage, it may not be possible to perform this in patients with multiple and fragile cysts. In such cases, the neural structures should be adequately decompressed and albendazole should be administered promptly. The authors describe the case of a 13-year-old girl who was admitted with a history of back pain and acute-onset lower-extremity weakness. Magnetic resonance imaging scans demonstrated severe spinal cord compression caused by multiple cysts involving T-4 and the mediastinum. The patient underwent surgery, and the cysts were removed, except for one cyst that was hardly exposed. Following histopathological confirmation of spinal hydatid disease, she was treated with albendazole for 1 year. One year postoperatively, the residual cyst had gradually shrunk and had almost disappeared. Although a single case is not sufficiently promising, we believe that administration of albendazole is efficient to prevent recurrences in cases in which it is not possible to obtain total removal of the cysts without inducing spillage.
