Single small enhancing computed tomographic (CT) lesions representing cysticercus granuloma are a common cause of focal seizures in children. Controversy exists regarding the efficacy of various modalities of treatment. We conducted a randomized prospective trial to evaluate the efficacy of corticosteroids, albendazole, and corticosteroids with albendazole in children with focal seizures and single small enhancing CT lesions. The study population consisted of 133 children with focal seizures of recent onset (< 3 months) and single small enhancing CT lesions who presented to the Neurocysticercosis Clinic of Pediatric Neurology Services at the Advanced Pediatrics Centre, Postgraduate Institute of Medical Education and Research, an urban teaching and tertiary care hospital in Chandigarh, North India. All children were randomly assigned to receive corticosteroids (group S), albendazole (group A), or both corticosteroids and albendazole (group SA) for 28 days. CT was done at 3 and 6 months after enrollment in the study. Of the 133 patients enrolled, 23 were lost to follow-up. Of the remaining 110 patients, 38 patients were in group S, 37 in group A, and 35 in group SA. All children were followed up for at least 18 months. Disappearance of the lesion on CT scan was noted in 52.6% of patients in group S, 59.5% in group A, and 62.9% in Group SA (P > .1) at the 3-month follow-up. After the 6-month follow-up, disappearance of the lesion was noted in 76.3% in group S, 75.7% in group A, and 74.2% in group SA (P > .1). Twenty-three patients had seizure recurrence while on antiepilepsy drugs: 36.8% of patients in group S, 13.5% in group A, and 11.4% in group SA (P < .05). Seizure recurrence after antiepilepsy drug withdrawal was seen in seven children (three in group S and two each in groups A and SA). In conclusion, there was no significant difference in resolution of CT lesions in the three therapy groups at 3 and 6 months of follow-up. Children in the corticosteroid group had significantly more seizure recurrences while on antiepilepsy drugs. To determine the efficacy of albendazole plus dexamethasone in children with 1 or 2 ring-enhancing lesions (by computed tomography scan) on resolution of lesions and recurrence of seizure.
                Randomized controlled open trial.
                Children of either sex, 1 to 14 years of age, with seizures and 1 or 2 ring-enhancing lesions <20 mm in diameter on computed tomography scan, likely to have neurocysticercosis, were assigned to treatment l groups. Children assigned to the treatment group (n=61) were given 0.15 mg/kg per day dexamethasone for 5 days plus 15 mg/kg per day albendazole for 28 days, starting on the third day of dexamethasone. Control group (n=62) children were given neither dexamethasone or albendazole. Anti-epileptic therapy was given to both the study groups.
                The lesions resolved completely or partially in more children in the treated group compared with the control group (79% versus 57%; P=.02). The proportion of children who had seizures was significantly lower in the treated group compared with the control group at 3 months (10% versus 32%; P=.006) and 6 months (13% versus 33%; P=.03).
                Albendazole plus dexamethasone increased complete or partial resolution of lesions and reduced the risk of subsequent recurrence of seizures among children with neurocysticercosis who had with seizures and 1 or 2 ring-enhancing lesions on computed tomography. Neurocysticercosis is a common cause of acquired seizure disorder in developing countries, including India. The role of antiparasitic (albendazole) therapy for seizure control and resolution of lesions is still controversial due to a lack of adequately controlled studies. The objective of the present study was to evaluate the role of albendazole therapy for neurocysticercosis patients with two or more lesions to achieve seizure-free status and resolution of lesions. This was a randomised controlled study in which patients suffering from neurocysticercosis were prospectively followed up for more than 5 years (from January 1997 to January 2005). Patients were divided into two groups: patients in group A (n=150) were treated with a combination of tapered doses of dexamethasone and albendazole, plus antiepileptic drugs; patients in group B (n=150) were treated with antiepileptic drugs plus a placebo control. Patients were followed up every month for the first 6 months and then at 3-month intervals thereafter up to 5 years. Variables of interest were (i) recurrence of seizures; (ii) encephalopathy (headache/vomiting/altered sensorium); (iii) need for subsequent hospital admission; (iv) death; (v) resolution of lesions on follow-up CT. During the first 6 months and at intervals thereafter, increased seizure frequency and hospital readmissions, and increased incidence of encephalopathy were observed in group A (p=0.01), and two patients in this group died with intractable seizures and encephalopathy. A greater proportion of lesions completely resolved in group B (p=0.05), whereas a greater proportion of lesions calcified in group A (p=0.05). Albendazole plus antiepileptic drugs did not have greater beneficial effects than antiepileptic drugs alone, but may have an adverse effect with respect to seizure control, encephalopathy, recurrent hospital admissions, calcification of lesions and cost of treatment. A combination of albendazole and praziquantel was more effective than albendazole alone in destroying Taenia cysts in an animal model. There are no such studies in humans.
                To evaluate the efficacy and safety of a combination of albendazole and praziquantel in children with seizures and single small enhancing computerized tomographic lesions.
                Prospective, interventional, randomized, placebo-controlled, double blind clinical trial at a tertiary hospital in North India.
                : One hundred twelve children with seizures for <3 months and single lesion neurocysticercosis; 9 lost to follow-up.
                All children received albendazole (15 mg/kg/d) for 7 days with either praziquantel or placebo (75 mg/kg/d) for 1 day according to random allocation. Repeat CT scans were done after 1, 3, and 6 months. All children were followed up for at least 6 months.
                Fifty-three children received praziquantel (group A) and 50 placebo (group B). Complete resolution of lesions was seen in 60% and 72% of children at 3 and 6 months in group A versus 42% and 52% of children in group B. Nonresolution and calcification were higher in group B than in group A at 3 months (B: 28%, 14%; A: 12%, 8%) and 6 months (B: 16%, 22%; A: 6%, 9%), but the differences were not statistically significant. Seizure control and side effects were similar in the 2 groups.
                A combination therapy for albendazole and praziquantel was statistically comparable to sole therapy with albendazole in eradicating lesions and preventing seizures. Single small enhancing computerized tomographic (CT) lesions (SSECTLs) are common in children with focal seizures. These are considered to represent solitary cysticercus granulomas. Controversy exists regarding their treatment.
                To evaluate the efficacy of albendazole in cases of focal seizures with SSECTLs.
                Randomized, placebo-controlled, double blind trial.
                Pediatric service of Nehru Hospital, PGIMER, an urban tertiary care teaching hospital.
                63 children between 2 and 12 years of age with focal seizures for <3 months and SSECTLs.
                All children were randomly assigned to receive either albendazole (15 mg/kg/ day) or placebo for 28 days. CT scan was done at 1 and 3 months after beginning treatment. Codes opened after 6 months of inclusion in the study showed that 31 had received albendazole and 32 had received placebo. All children were followed up for at least 15 months.
                Disappearance of lesions on CT scan was noted in 41% of albendazole vs. 16.2% of placebo patients after 1 month of follow-up (P < 0.05) and 64.5% of albendazole- vs. 37.5% of placebo-treated patients after 3 months of follow-up (P < 0.05). During the first 4 weeks of therapy seizure recurrence was seen in 9.7% of albendazole vs. 3.2% of placebo-treated children (odds ratio, 3.32; 95% confidence interval, 0.33 to 33.8). After 4 weeks seizure recurrence was seen in 31.3% of placebo-treated children vs. 12.9% of albendazole-treated children (odds ratio, 3.07; 95% confidence interval, 1.18 to 11.15).
                Albendazole therapy results in significantly faster and increased resolution of solitary cysticercus lesions (SSECTLs) and appears to reduce the risk of late seizure recurrences. No trials to date have focused on long-term seizure outcome in solitary cerebral cysticercal lesion (SCCL), which is believed to produce a relatively benign form of epilepsy. This is a prospective randomized controlled study to evaluate the effect of Albendazole on long-term seizure outcome in patients with MRI-confirmed solitary cerebral cysticercal lesion (SCCL). One hundred and twenty-three patients with new-onset seizures and SCCL on contrast MRI were randomized to treatment with albendazole and followed for up to five years with serial MRI and clinical evaluation. At final analysis 103 patients (M-54, F-49) with a mean age of 18.6+/-10.7 years and follow-up period more than 12 months were included. The mean follow-up duration was 31.4+/-14.8 months (12-64). At one month follow-up more patients receiving albendazole were seizure-free (62% versus 49% for controls). Subsequently there was no significant difference in overall seizure outcome between the two groups. There was no correlation between seizure semiology, albendazole therapy and long-term seizure outcome. Baseline MRI showed active lesions in all; 23% remained active at 12 months with no difference between the albendazole and control groups. Patients whose lesions resolved at 12 months showed better seizure outcome. Reduction in mean cyst area was greater in the albendazole group as compared to the controls and the difference at six months was significant (p<0.05). At three months follow-up perilesional edema also resolved faster in albendazole group (p<0.05). Thus, albendazole did not alter the long-term seizure outcome in patients with SCCL and epilepsy. However, albendazole hastened resolution of SCCL on MRI, but interestingly 23% of lesions were still active 12 months after treatment. The clinical findings of neurocysticercosis, diagnosed primarily on the basis of computed tomography (CT), and response to albendazole therapy in a randomized, double-blind, placebo-controlled trial were studied in 72 newly diagnosed children aged 1.5-12 years admitted to hospital in New Delhi, India, during March to July 2000. The lesions by initial CT were mostly single with perilesional oedema, and were located in the parietal lobes. The most common clinical finding was partial seizure (79.2%). The outcome of the albendazole trial was assessed through changes in CT lesions and status of seizure after 6 months of follow-up; about 55% of the lesions had disappeared and about 80% of the children were seizure-free. The frequency of healing of CT lesions in the albendazole-treated group and placebo group was 54.2% and 55.2%, respectively, and the frequency of a seizure-free state in the albendazole-treated group and placebo group was 87.5% and 77.5%, respectively; the differences were not statistically significant. Changes in lesions by CT and the recurrence of seizures after 6 months of follow-up were not related to the number of lesions by initial CT and albendazole was not beneficial in neurocysticercosis in children with ring-enhancing lesions in CT. Neurocysticercosis is the main cause of adult-onset seizures in the developing world. Whether therapy with antiparasitic agents results in improved seizure control has been questioned because of the lack of adequate, controlled studies.
                We conducted a double-blind, placebo-controlled trial in which 120 patients who had living cysticerci in the brain and seizures treated with antiepileptic drugs were randomly assigned to receive either 800 mg of albendazole per day and 6 mg of dexamethasone per day for 10 days (60 patients) or two placebos (60 patients). The patients were followed for 30 months or until they had been seizure-free for 6 months after the doses of the antiepileptic drugs had been tapered. The efficacy of treatment was measured as the decrease in the number of seizures after treatment.
                In the albendazole group, there was a 46 percent reduction in the number of seizures (95 percent confidence interval, -74 to 83 percent) during months 2 to 30 after treatment. This reduction, which was not statistically significant, was composed of a nonsignificant reduction of 41 percent in the number of partial seizures (95 percent confidence interval, -124 to 84 percent) and a significant 67 percent reduction in the number of seizures with generalization (95 percent confidence interval, 20 to 86 percent). Most of the difference in the number of partial seizures was attributable to a few patients who had many seizures during follow-up. The proportions of patients who had partial seizures during follow-up were similar in the two groups (19 of 57 in the albendazole group and 16 of 59 in the placebo group), but the patients in the placebo group had a greater tendency to have seizures with generalization (22 of 59, vs. 13 of 57 in the albendazole group; risk ratio, 1.63; 95 percent confidence interval, 0.91 to 2.92). More of the intracranial cystic lesions resolved in the albendazole group than in the placebo group. With the sole exception of abdominal pain, side effects did not differ significantly between the two groups.
                In patients with seizures due to viable parenchymal cysts, antiparasitic therapy decreases the burden of parasites and is safe and effective, at least in reducing the number of seizures with generalization.
                Copyright 2004 Massachusetts Medical Society The appropriate duration of albendazole therapy in neurocysticercosis remains to be determined. Observations in small, uncontrolled clinical trials that short course therapy is as effective as longer regimens must be tested by proper trials.
                To compare efficacy of 1 and 4 weeks of albendazole therapy in children with neurocysticercosis.
                A randomized, placebo-controlled, double blind clinical trial at the Pediatric Neurocysticercosis Clinic of Advanced Pediatric Centre, a tertiary care teaching hospital.
                We observed 122 consecutive children with seizures and either a single small enhancing computerized tomographic lesion or up to 3 lesions on head computerized tomography (CT) examination.
                All children received albendazole (15 mg/kg/day) for 7 days followed by either albendazole or placebo for the following 21 days according to their random number allocation. CT scans were repeated at 1 and 3 months after completion of therapy. Codes opened at the completion of study revealed that 60 children had received albendazole for 28 days (Group A) and 62 received albendazole for 7 days (Group B). All children were followed for at least 2 years.
                Complete resolution of lesions was similar in the two therapy groups on the first (42% vs. 39%) and second (77% vs. 79%) follow-up CT. Reduction in total number and size was also similar. Also the proportion of lesions that calcified (5% vs. 10%) did not differ significantly. Seizure control at 2 years was similar in the 2 groups.
                In this clinical trial 1 week of albendazole therapy was as effective as 4 weeks of therapy in children with neurocysticercosis having one to three lesions. Single, small, enhancing lesions that often resolve spontaneously are frequent findings on CTs of Indian patients with seizures. Based on ELISA and biopsy data, the majority of these lesions are probably cysticercosis. To determine if these patients should be treated with albendazole, we performed a double-blind, randomized, placebo-controlled study involving 75 patients with seizures and the appropriate CT abnormality without neurologic abnormality on examination. Patients were randomized to albendazole (15 mg/kg/d) and placebo for 1 week, and we obtained serial CTs at the end of 1 week, 1 month, and 3 months. All patients completed a 3-month follow-up and none had systemic evidence of tuberculosis or cysticercosis. The lesions varied in size from 3 mm to 2.1 cm, with an average size of 1.18 cm. Serum ELISA for cysticercosis was positive in 30 and CSF ELISA was positive in 20 of 45 patients. Forty patients received albendazole and 35 received placebo. At the end of 3 months, a total of 68 patients showed resolution. Thirty-five of 40 patients who received albendazole showed resolution, as opposed to 33 of 35 patients on placebo. We conclude that albendazole therapy was not beneficial. The aim of this trial was to evaluate the effects of albendazole (ALB) on cyst disappearance, reduction of the number of cysts and seizure recurrence.
                178 patients with new onset symptoms due to active or transitional neurocysticercosis were randomly assigned to receive either 800 mg of ALB daily or placebo for 8 days. All patients also received prednisone. Imaging studies were done at baseline and at months 1, 6 and 12 of follow-up.
                Active cysts were identified in 59 of 88 people randomised to ALB and 57 of the 90 in the placebo arm. By 1 month, 31% were free of active cysts in the treatment group compared with 7% in the placebo group (p = 0.001). In addition, the ALB group had a greater reduction in the number of active cysts compared with the placebo group (p = 0.001). After 1 month following treatment there was no additional gain by treatment group in the disappearance or reduction in the number of active cysts. ALB treatment had little effect on cysts in the transitional or calcification stage. We found no difference between the ALB and placebo groups in symptoms during treatment or in seizure recurrence during the 12 months after treatment.
                Albendazole plus symptomatic treatment leads to the disappearance of active cysts in 31% of patients compared with 7% of those with symptomatic treatment alone. This treatment effect occurs within the first 30 days after treatment. Trial registration number: NCT00283699. Neurocysticercosis is a major cause of neurologic illness worldwide. Its manifestations are variable, and somewhat different when it occurs in children. Controversy exists regarding anticysticercal therapy. The clinical, laboratory, and radiographic features of 500 consecutive children with neurocysticercosis were studied; the children were then followed prospectively and their response to albendazole therapy was analyzed. Diagnosis of neurocysticercosis was based primarily on neuroimaging. Computed tomographic (CT) scans, neurocysticercosis serology, chest radiographs, and Mantoux tests were done in all children, and magnetic resonance imaging scans in 10%. All children with multiple lesions, and some randomly allocated children with single, small, enhancing CT lesions received albendazole. CT scans were repeated after 3 to 6 months. There were 272 boys and 228 girls, age range 1 6/12 to 12 6/12 years. Seizures were present in 94.8% of cases; 83.7% had focal seizures. Features of raised intracranial pressure were seen in 30% of patients and focal neurodeficit in 4%. Single lesions were seen in 76% of the children, with perilesional edema in 57.4%. Thirty-four children who had multiple cysts and received albendazole underwent serial CT evaluation. Four showed disappearance of lesions and 22 had reductions in the size or number, to give an overall improvement rate of 76%. Serial CT studies were available on 176 children with single lesions, 90 of whom received albendazole. Improvement (disappearance or reduction in the size of lesions) was observed in 91% (82 of 90) of albendazole-treated children versus 85% (73 of 86) of untreated children. This difference was not significant. No significant side-effects of albendazole were reported. These data indicate that partial seizures and single parenchymal cysts are the most frequent clinical and neuroradiographic manifestations of neurocysticercosis in children. Although albendazole therapy should be considered, especially in children with multiple lesions, many children with isolated neurocysticercosis will improve without antiparasitic therapy. Praziquantel and albendazole have been recently described as effective drugs for treating cysticercosis of the brain. In this study, effectiveness of each drug for therapy for parenchymal brain cysticercosis was compared. Twenty patients were treated either with albendazole or with praziquantel; in addition, five patients were taken as controls and treated only with symptomatic drugs. Three months after therapy, results showed that both drugs, albendazole and praziquantel, were highly effective, as seen by the disappearance of cystic lesions in computed tomographic scans. All lesions in control patients remained unchanged. Albendazole, when compared with praziquantel, showed a 76% vs 73% disappearance of lesions, respectively. It was concluded that both drugs have similar equivalent efficacy and greatly improve the therapeutics of cysticercosis. In India, parenchymatous cysticercus cysts are more common than the meningeal racemose variety which are seen frequently in Latin America. Reports from Mexico suggest that albendazole is effective in the treatment of neurocysticercosis. We, therefore, studied whether this drug changed the natural course of neurocysticercosis in India.
                In a randomized, double-blind, placebo controlled study, we allocated 29 consecutive patients (22 men and 7 women) with multiple cystic lesions on computed tomography (CT) of the head suggestive of cysticercosis to 7 days treatment with albendazole (15 mg/kg/day) or placebo. CT scans were repeated at the end of treatment and 1 and 3 months later to assess the number of cysts and extent of oedema.
                Sixteen patients received albendazole and 13 placebo. No change was seen at the end of one week. At 3 months, 14 patients in the albendazole group and 10 in the placebo group showed more than 25% reduction in the number of lesions. The difference between the two groups was not significant.
                Albendazole given in a dose of 15 mg/kg/day for 1 week does not change the natural course of neurocysticercosis. Albendazole has been used successfully in the treatment of cerebral cysticercosis for several years. The published dosage schedule has varied from 15 mg/kg/day for 8 days to up to 30 days. Fifty three patients with neurocysticercosis received 8, 15 or 30 days treatment with 800 mg of albendazole daily. The present study demonstrates the effectiveness in clinical and radiological terms of albendazole 800 mg/day for 8 days for the majority of patients affected with cystic or encephalitic parenchymatous cysticercosis. There was no apparent advantage of continuation of treatment for 15 or 30 days in this series. The routine use of high dose steroids limited the effects of parasite destruction. No toxicity attributable to albendazole was encountered. Thirty-six patients with subarachnoid and intraventricular cysticercosis were randomly assigned to receive albendazole at 15 or 30 mg/kg/day plus dexamethasone for 8 days. Results favored a higher dose, with larger cyst reduction on MRI at 90 and 180 days and higher albendazole sulfoxide levels in plasma. An albendazole course at 30 mg/kg/day combined with corticosteroids is safe and more effective than the usual dose. A single treatment was insufficient in intraventricular and giant cysts. A double-blind placebo-controlled study of the concurrent administration of albendazole and praziquantel was conducted in>1500 children with high prevalences of geohelminths and schistosomiasis. The study sites were in China and the Philippines, including 2 strains of Schistosoma japonicum, and 2 different regions of Kenya, 1 each with endemic Schistosoma mansoni or Schistosoma haematobium. Neither medication affected the cure rate of the other. There was no difference between the side effect rate from albendazole or the double placebo. Praziquantel-treated children had more nausea, abdominal pain, and headache but these side effects were statistically more common in children with schistosomiasis, suggesting a strong influence of dying parasites. The subjects were followed for 6 months for changes in infection status, growth parameters, hemoglobin, and schistosomiasis morbidity. In all 4 sites, a significant 6-month increase in serum hemoglobin was observed in children who received praziquantel, strongly supporting population-based mass treatment. To compare the effectiveness of two regimens of albendazole therapy for neurocysticercosis.
                Randomized, double-blind clinical trial.
                Patients admitted to neurologic wards in Lima, Peru.
                Adult patients with active neurocysticercosis demonstrated by CT and Western blot (immunoblot).
                One week (n = 25) versus 2 weeks (n = 25) of albendazole therapy.
                Decrease in the number of cysts on CT.
                Effectiveness of albendazole was 78%, with no difference between the groups when compared 3 months after therapy. Complete cure was obtained in only 38% of patients. Patients with more than 20 cysts had poorer responses to therapy. The clinical course and EEG evolution improved in most patients. Side effects were present in 38% of patients, mainly mild, transient gastrointestinal symptoms. Therapy was also associated with exacerbation of neurologic symptoms. Two patients died in the first year after therapy, both because of aggregated infections of ventricle-peritoneal shunts. One-year follow-up CT showed lesions in three of 10 patients presumed to be cured 3 months after therapy.
                Extension of albendazole therapy for more than 7 days adds no benefits for the patients. Eighteen patients with nonenhancing parenchymal brain cysts were treated with albendazole; 9 patients were treated for 3 days and 9 patients for 1 month at daily doses of 15 mg/kg of body weight. Three months after starting therapy, results showed that in both groups the treatment was highly effective. Control studies carried out in the same group before the trial did not show any significant improvement. Five patients were controls and were treated only with symptomatic drugs. The total diameter of the lesions was reduced from 220.1 mm to 52.1 mm, which signifies a reduction of 76.3% in patients treated for a period of 3 days, and from 278.5 mm to 82.1 mm, which is 70.5%, in patients treated for 30 days. We conclude that albendazole administered according to the 3-day therapeutic scheme proposed above is as highly effective for the treatment of parenchymal brain cysticercosis as the 30-day scheme. The efficacy of albendazole (15 mg/kg/d for 1 week) was compared with praziquantel (100 mg/kg in three divided doses at 2-hour intervals) for therapy of parenchymal brain cysticercosis. Ten patients were treated with albendazole and 10 patients with praziquantel. Although the total number of cysts was significantly reduced from 64 to 7 in patients treated with albendazole and from 59 to 24 in those treated with praziquantel, the number of patients improving with albendazole was not significantly different from those treated with praziquantel.
In patients with viable lesions, evidence from trials of adults suggests albendazole may reduce the number of lesions. In trials of non-viable lesions, seizure recurrence was substantially lower with albendazole, which is counter-intuitive. It may be that steroids influence headache during treatment, but further research is needed to test this.
