In January and February 1974, 32 adults (20 males and 12 females) and a 13-year-old girl with taeniasis saginata were treated with the mixture of boiled areca nuts and pumpkin seeds at Mastoban, Jen-ai District, Nantou County, Taiwan. A total of 48 worms including 42 scolices were recovered from 29 cases. Side-effects were observed in 4 cases including 3 with complaints of dizziness, tinnitus, nausea and vomiting, and one with coma and abdominal pain. Mixtures of 75-150 g areca nuts and 50-100 g pumpkin seeds were judged effective and safe.

A total of 118,925 individuals in four Nigerian states was treated for onchocerciasis between February and December, 1991, using centralized and house-to-house distribution of ivermectin. Pre-treatment prevalences of the disease ranged between 28% and 90%. Only 0.7% of those treated reported adverse reactions within three days of treatment: 230 individuals (0.19%) had headache, 210 (0.17%) general body pains, 150 (0.12%) pruritus, 120 (0.10%) oedema, 80 (0.06%) fever, 20 (0.02%) dizziness, 15 (0.01%) vomiting, 10 (0.01%) diarrhoea, and 25 individuals (0.02%) noticed that they passed intestinal worms. Treatment in the endemic communities continues. The results show that mass treatment of onchocerciasis with ivermectin is quite safe and the drug's acceptability increases its potential as the drug of choice for control of onchocerciasis in Nigeria.

The objective of this multidisciplinary clinical investigation was to test whether amocarzine was absorbed effectively and safely in patients of two races and either sex infected with Onchocerca volvulus while living in the holoendemic area of Esmeraldas Province, Ecuador. The prerequisite for a systemic onchocercacidal effect is the regular absorption of orally administered amocarzine. Single dosing after overnight fasting proved to produce irregular absorption of amocarzine, although some microfilaricidal effect was achieved. A pilot study with repeated low dose and postprandial administration of amocarzine showed a regular and predictable absorption with acceptable tolerability and a microfilaricidal effect lasting up to one year post-therapy. Since amocarzine and its major N-oxide metabolite are coloured agents, urine colorimetry was used to assess the urinary excretion of the N-oxide qualitatively. For the postprandial drug regimens plasma concentrations of amocarzine and its metabolite were determined at two selected time points in patients of two races and either sex; the results showed no major differences. Excision of onchocercal nodules was performed four months post-therapy. The pooled results of the histologic analysis of 100 patients with the same drug regimen read under blinded condition showed that 65% of the adult female worms were dead, 20% necrobiotic and 15% alive. The male worms were fewer and mainly necrobiotic. Control worm populations in Esmeraldas without chemotherapy showed that on the average 81.5% were alive and 18.5% dead. Amocarzine was also microfilaricidal producing a reduction of skin dwelling microfilariae to about 10% of the initial value within the first week after start of therapy and lasting for half a year at a 20% level. The reduction of ocular microfilarial was slower and reached 35-40% after one year. The general tolerability was acceptable to good. Reversible dermal reactions were usually mild and peaked as a rash in 57% of the patients on day 6. No prohibitive ocular intolerance was observed. Mild and reversible dizziness peaked on day 4 in 74% of patients. A positive reversible Romberg sign was found in 12 patients on day 4. Amocarzine, the first oral micro- and macrofilaricidal agent administered as a low dose repeat regimen (3 mg/kg twice daily and postprandial for three consecutive days) can be recommended for oral onchocercacidal therapy in adult patients. Clinical trials in juveniles should be encouraged.

The present field trial attempts to test the efficacy of niclosamide by a modified chemotherapeutic schedule to collect the purged stool samples consecutively to search expelled worms. Nineteen patients with taeniasis were given 1 gm of niclosmaide with 3 gm sodium bicarbonate twice at 30-minute interval, then purgative was administered. The patients were allowed only fluid meal or fruit juice before treatment. In all, 33 worms (11 with scolex, 22 without), 17 strobilae and 247 segments were collected from consecutive purged stools. The scolex recovery rate was 33%. After taking the purgative, 5 female patients showed side-reactions (nausea, vomiting and dizziness) which were mild and transient. Two months after the treatment, 14 patients were still passing strobilae and/or proglottides in the stools but 5 were not. Four months after the treatment, only 3 cases were still passing strobilae and/or segments in the stools showing a cure rate of 84.2%. The results indicate that niclosamide is a good taenicide but with a slow effect.

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.

Six species of Paragonimus have been reported in Thailand: P. siamensis in cat, bandicoot and rat; P. bangkokensis in mongoose; P. harinasutai in cat and dog (experiment); P. macrochis in bandicoot and rat; P. westermani in tiger and P. heterotremus in cat, dog and man. It is interesting to note that in 1965 two immature P. heterotremus worms were recovered for the first time in man, namely in subcutaneous swellings in a boy; in 1981 nine mature P. heterotremus worms were expectorated after praziquantel treatment. P. heterotremus has been postulated to be the main cause of human paragonimiasis in Thailand. The clinical manifestation of paragonimiasis heterotremus is similar to paragonimiasis westermani. In the 1960's and 1970's bithionol was used to treat paragonimiasis, the cure rate was only 50-60%, and side effects including urticaria, rash, abdominal pain, nausea, vomiting, diarrhoea and dizziness were common. In the past 4 years, niclofolan and praziquantel (2-cyclohexyl-carbonyl-1,2,3,6,7,11b-hexahydro - 4H - pyrazino [2,1-a]isoquinolin-4-one, EMBAY 8440, Biltricide) have been used. A single dose of 2 mg/kg body weight of niclofolan yielded 100% cure rate. Praziquantel at dosages of 3 X 25 mg/kg body weight daily for one day and two days gave 80% and 100% cure rates, respectively. The eggs disappeared in 2-3 weeks with improvement of symptoms and signs, but radiologically lesions took a few months or more to clear, depending on size and severity. Side effects in the niclofolan group were higher; in the praziquantel group side effects were minimal and no toxic effects were detected.

Fourteen patients with active schistosomiasis mansoni in spite of previous treatment with oxamniquine and/or hycanthone were treated with praziquantel, single oral dose of 45 to 50 mg/kg body-weight. All underwent clinical, laboratory and electrocardiographic examination before and after treatment. Untoward effects (dizziness, drowziness, nausea and abdominal pain) were observed in ten. Laboratory findings disclosed no significant alteration and the electrocardiograms showed no abnormalities. Monthly follow-up examinations of 13 patients for six consecutive months showed parasitological cure in all. Before praziquantel treatment strains of Schistosoma mansoni were isolated from two patients, one treated three times with oxamniquine and the other with hycanthone once and oxamniquine twice. Progenies of these strains were maintained in Biomphalaria glabrata and mice. Groups of these infected mice were then treated with oxamniquine, hycanthone, niridazole and praziquantel and results compared with the BH strain maintained in our laboratory for many years. Schistosomicidal activity was assessed by the localization of worms in the portal vein system and oogram changes. Progenies from the strains isolated in this study were resistant to oxamniquine and hycanthone but sensitive to niridazole and praziquantel. The BH strain was sensitive to all four drugs. The serial runs of S. mansoni strains through intermediate and definitive hosts have not influenced their reactions to these schistosomicides.

The hundred men from a forest area of Ghana, without vector control or ivermectin distribution, were randomized to receive a single dose of ivermectin (150 micrograms/kg body weight) on day 1 followed by amocarzine (3 mg/kg twice daily after meals) on days 8, 9 and 10 (34 patients), the ivermectin alone (33 patients) or the amocarzine alone (33 patients). Detailed clinical and laboratory examinations were made before, during and after drug administration. On day 120, all palpable nodules were excised, fixed, sectioned, stained and examined by two blinded observers and the results compared with those for nodules from untreated controls. Mazzotti-type reactions, such as itching, rash, peripheral sensory phenomena and swellings, were more severe or frequent with amocarzine than ivermectin. Pretreatment with ivermectin markedly suppressed these reactions to amocarzine but did not affect other manifestations such as dizziness and gaze-evoked nystagmus. Ocular effects were minor in all groups. Ivermectin produced minor macrofilaricidal effects on the adult male worms, marked degeneration of intra-uterine embryos, and potent microfilaricidal effects and suppressed skin microfilariae. Amocarzine did not affect the male worms or the intra-uterine embryos, was a less potent microfilaricide and did not suppress skin microfilariae. The efficacy of ivermectin plus amocarzine was similar to that of ivermectin alone. The present results do not support the findings from the Americas and show that amocarzine has no role in the treatment of onchocerciasis in Africa.

Feverfew (Tanacetum parthenium L.) (Asteraceae) is a medicinal plant traditionally used for the treatment of fevers, migraine headaches, rheumatoid arthritis, stomach aches, toothaches, insect bites, infertility, and problems with menstruation and labor during childbirth. The feverfew herb has a long history of use in traditional and folk medicine, especially among Greek and early European herbalists. Feverfew has also been used for psoriasis, allergies, asthma, tinnitus, dizziness, nausea, and vomiting. The plant contains a large number of natural products, but the active principles probably include one or more of the sesquiterpene lactones known to be present, including parthenolide. Other potentially active constituents include flavonoid glycosides and pinenes. It has multiple pharmacologic properties, such as anticancer, anti-inflammatory, cardiotonic, antispasmodic, an emmenagogue, and as an enema for worms. In this review, we have explored the various dimensions of the feverfew plant and compiled its vast pharmacologic applications to comprehend and synthesize the subject of its potential image of multipurpose medicinal agent. The plant is widely cultivated to large regions of the world and its importance as a medicinal plant is growing substantially with increasing and stronger reports in support of its multifarious therapeutic uses.

Taeniasis refers to the infection with adult tapeworms of Taenia spp. in the upper small intestine of humans, which is also a cause of cysticercosis infection in either both humans and/or animals. Currently the most commonly applied anthelminthics for treatment of taeniasis are praziquantel and niclosamide. Praziquantel is very effective, but has the risk of induction of epileptic seizures or convulsions in carriers with asymptomatic concurrent neurocysticercosis. In contrast, niclosamide is safe and effective, but is not readily available in many endemic countries including China. In the current community-based study, we assessed the curative effect of either pumpkin seeds or areca nut extract alone in taeniasis, and also looked at synergistic effects of these two herb drugs on tapeworms. In the study group with the pumpkin seed/areca nut extract treatment, 91 (79.1%) of 115 suspected taeniasis cases (with a history of expulsion of proglottids within the previous one year) released whole tapeworms, four (3.5%) expelled incomplete strobila, and no tapeworms or proglottids were recovered in the remaining 20 cases. In these 115 persons, 45 were confirmed as taeniasis before treatment by microscopy and/or coproPCR. Forty (88.9%) of 45 confirmed cases eliminated intact worms following treatment. The mean time period for complete elimination of tapeworms in 91 taeniasis cases was 2 h (range 20 min to 8 h 30 min), and 89.0% (81) of 91 patients discharged intact worms within 3h after drug administration. In Control Group A with treatment of pumpkin seeds alone, 75.0% (9/12) of confirmed taeniasis cases expelled whole tapeworms, but the mean time period for complete elimination was about 14 h 10 min (range 3 h 20 min to 21 h 20 min), which was much longer than that (2 h) for the study group, whereas in Control Group B treated with areca nut extract alone, only 63.6% (7/11) of taeniasis cases discharged whole tapeworms, and the mean time period was 6 h 27 min (range 1-22 h). Mild side effects included nausea and dizziness in about 46.3% of patients with the pumpkin seeds/areca nut extract treatment, but all discomforts were transient and well tolerated. In conclusion, a synergistic effect of pumpkin seed and areca nut extract on Taenia spp. tapeworms was confirmed in the current study, primarily in producing an increased rate of effect on tapeworm expulsion (average time 2 h for combination vs 6-21 h for individual extracts). The pumpkin seed/areca combined treatment was indicated to be safe and highly effective (89%) for human taeniasis.
