The clinical and laboratory data of 88 black patients with computed tomographic (CT) evidence of active neurocysticercosis were analysed. The CT appearance of neurocysticercosis was distinctive in the majority. Seizures, chronic headache and neuropsychiatric changes were the most common clinical presentations. Hydrocephalus was diagnosed in 17 patients (9 obstructive and 8 communicating) and cerebral infarction with focal neurological deficit occurred in 4 cases. All patients were treated with praziquantel (Biltricide: Bayer Miles). There was complete cyst clearance after two courses in 14 patients and in 16 cases the mean percentage reduction in cyst number was 85.88% and in cyst size 80.84%. In 1 patient there was no response to treatment. Although praziquantel was effective in parenchymal neurocysticercosis, it was ineffectual in the treatment of 5 patients with cysticercal meningitis. There were 2 deaths in the series.

Praziquantel (2-cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4H-pyrazino[2,1-a]++ +isoquinolin- 4-one, EMBAY 8440, Biltricide) has been used in 4853 patients with Opisthorchis viverrini infection. 786 patients were treated as inpatients with extensive clinical evaluation and the rest were out-patients. A cure rate (evaluated with 5 faecal samples) of 100% was obtained in groups given 6 X 25 mg/kg on 2 days and 3 X 25 mg/kg on 1 day, while in groups given 2 X 25 mg/kg, 1 X 25 mg/kg and 1 X 40 mg/kg all on 1 day the cure rates were 88, 44 and 91%, respectively. With one sample evaluation the parasitological cure rate was 96% in further 96 patients excreting the geometric mean (GM) of 5394 eggs per gram (EPG) and receiving 1 X 40 mg/kg. Another 68 patients with an egg output of 26044 (GM/EPG) and treated with 1 X 50 mg/kg showed a cure rate of 97% by similar evaluation. Side effects were mild and transient and were more frequent in higher dosage groups. They included anorexia, nausea, vomiting, abdominal pain, epigastric pain, rumbling in the abdomen, diarrhoea, lassitude, myalgia, headache, dizziness, sleeplessness, sleepiness, "hot sensation", shortness of breath, and skin rash in a few cases. Headache (30.7%) was most common in the 6 X 25 mg/kg group. In 53 patients with severe jaundice the side effects were similar. There was no evidence of toxicity. Remarkable was one patient treated with 1 X 50 mg/kg who expelled 5636 O. viverrini worms, most of which were elongated and damaged. When a single dose is prescribed it should be given at bed time to reduce the side effect of sedation.

108 patients coming to France from Southeast Asia were treated with praziquantel (2-cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4H-pyrazino[2,1-a] isoquinolin-4-one, EMBAY 8440, Biltricide) for opisthorchiasis. All patients, 31 children and 77 adults, were examined at the Department of Parasitic Diseases 30 to 90 days after arrival in France. They came from Laos (79 cases), Viet Nam (4 cases) and Cambodia (25 cases), generally via Thailand. 6 heavy (10 000-19 999 eggs per gram of faeces, EPG), 23 moderate (1000-9999 EPG) and 79 light infections (1-999 EPG) were detected. Praziquantel was given at a dose of 25 mg/kg body weight, three times on a single day at intervals of 4 h. The biological tolerability was excellent without any variation of the biological norm values (47 parameters). Clinical tolerability was perfect in 48 patients and pretty good in the 60 remaining cases. We only observed, for one or two days, lassitude, headache, drowsiness, nausea, epigastric pain or arthralgia-myalgia always of weak or moderate intensity. The therapeutic efficacy is remarkable with 100% cure in all patients who were followed-up for 90 days. All earlier controls (7th, 20th, 40th days) were always negative except for one child with a light infection still weakly positive at the 7th, 20th and 40th day controls but negative, too, after 90 days.

2-Cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4H-pyrazino [2,1-a]isoquinolin-4-one (praziquantel, EMBAY 8440, Biltricide) was administered to 78 patients aged from 6 to 18 years. They were divided into 3 groups, receiving single doses of 30 mg and 40 mg/kg b.w. and 2 doses of 20 mg/kg b.w. (at an interval of 6 h), respectively. Tolerance examinations showed that 65% of the patients treated did not complain of any side effects. The remaining patients mentioned abdominal pain, headache and/or nausea. All these symptoms disappeared within a few hours without special treatment. Compared with pretreatment results, clinical examinations after treatment did not reveal any significant changes of haematocrit, haemoglobin, transaminases and bilirubin. Follow-up urine examinations were carried out 6 months after treatment in 71 children, of whom 68 were found to be no longer excreting viable eggs of Schistosoma. This corresponds to a parasitological cure rate of 95.8%. In the three patients who were not cured the number of eggs excreted was reduced by 89.2%. No statistically significant difference in efficacy was recorded between the three doses administered. Praziquantel appears to be an effective, well tolerated and easily administrable schistosomicide and thus a favourable contribution to the control of urinary schistosomiasis.

41 patients (20 females and 21 males aged from 8 to 68 years) were prescribed 2-cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4H-pyrazino[2,1-a]isoquinolin-4-one(praziquantel, EMBAY 8440, Biltricide) at a dose of 25 mg/kg body weight given three times on a single day at intervals of 4 h, for the treatment of opisthorchiasis. Clinical as well as biological tolerance was followed up very closely, first during a hospitalization period of 6 days, then on day 20, 40, 90 or more after treatment. None of the biological controls consisting of a total of 47 parameters (haematological, biochemical, urinary) showed any variation from before to after treatment. Clinical examinations, recorded in very carefully prepared case report sheets, served for systematically screening general signs and symptoms (fever, headache, etc.), digestive manifestations or neurological signs. Tolerability was absolutely perfect in 10 patients. In the remaining 31 cases the following signs were observed: lassitude or vertigo (15 times), headache (14 times), drowsiness and nausea (5 times), epigastric pain (9 times), arthralgia-myalgia (3 times), sweating (1 time). All these signs lasted one or two days only and were of weak or moderate intensity, thus allowing the conclusion that even at higher dosages tolerability to praziquantel is excellent.

Praziquantel(Distocide), the Korean product, was tested for its safety and efficacy in treatment of Clonorchis sinensis infection during the period from April to September, 1983 in Korea. A total of 55 egg positive cases were selected and treated with the regimen of 25 mg/kg t.i.d. for 1 day (total 75 mg/kg). The follow-up stool examination was done in 47 cases by cellophane think smear and Stoll's egg counting techniques. The 8 uncured cases were treated again with the same regimen. The laboratory tests for blood picture and liver function were done in 27 cases and compared before and after the treatment. The results obtained are as follows: After single course treatment, the cure and egg reduction rates were 83.0% and 99.1% respectively. With the second treatment, excellent results of 100% in both rates were obtained. Several kinds of side effects such as dizziness, headache, etc. were complained by 29 cases (61.7%), however, those were so mild and transient that no special treatment was necessary. No significant chang in laboratory findings was recognizable before and after the treatment. From the above results, it is concluded that Distocide is as effective and safe as Biltricide(R) and highly recommendable in treatment of C. sinensis infection.
