Amoebic dysentery appears to be rare in the northeast of Tanzania. Hepatic amoebiasis, on the other hand, is apparently widespread since at least 200 cases are seen every year at the Kilimanjaro Christian Medical Centre. This incidence of cases enabled us to carry out trials on the spot with a new imidazole derivative, Tinidazole. Formerly the difficult diagnosis based on clinical symptoms had to be buttressed by radiological evidence and possibly by the result of puncture. Indirect fluorescent antibody tests for the diagnosis of amoebiasis were performed elsewhere on all the patients, using for this purpose microspecimens of dried blood. In 12 cases out of 34 an agglutination test with sensitized latex particles was performed on the spot. This latter test has the practical advantage of being easy to employ. It cannot, however, be considered as a screening test since it is subject to downward and upward errors. The indirect fluorescent antibody test has been found to be constantly and highly positive, certain antibody titres attaining 1/6400. This fully confirms the value of the method even under special working conditions. Seventeen of our 34 patients (2 women and 15 men ranging in age from 20 to 75 years) were treated with 2 g of Tinidazole per day in a single dose for 2 to 3 consecutive days. Puncture to evacuate pus was also performed where abscesses had collected. Tolerance on the whole was good without a single sign of cardiovascular or urinary toxicity. However, paraesthesia of the hands was observed in one case, transitory thrombocytopenia in one other patient, and increased alkaline phosphatases. Minor disorders were also observed in our series of patients: mild vertigo (7 cases), headache (6 cases), and dry mouth (2 cases). After 8 months the therapeutic results were as follows: 12 complete cures out of 17, 2 improvements with final cure probable, 3 partial failures necessitating supplementary treatment with Metronidazole (2.4 g per day for 2 days). These preliminary trials appear to the encouraging and the study is being continued with series compared with cases treated with Emetine or Metronidazole.

Metronidazole is an antimicrobial, antiprotozoal agent that has been widely used in the treatment of a variety of infections. Some therapeutic indications necessitate prolonged treatment with metronidazole. Peripheral neuropathy is a potential metronidazole-induced toxicity, which has been reported in only a few isolated retrospective studies. This prospective study was designed to determine the toxic profile of metronidazole in patients undergoing long-term treatment with this drug. In the present study, 17 patients of both sexes, aged between 20 and 50 years, with body weights ranging from 46 to 62 kg and who were suffering from various medical ailments were recruited. The patients received 400 mg t.i.d. oral metronidazole in a total dose of 16.8-39.6 g for 2-4 weeks. It was found that patients usually suffered from some of the toxic symptoms of metallic taste, headache and dry mouth and to a lesser extent nausea, glossitis, urticaria, pruritus, urethral burning and dark colored urine. Symptoms were irrespective of sex and directly proportional to duration of therapy. Deep tendon ankle jerks were maximally reduced in four patients and sense of vibration at the level of olecranon and patella was affected in two patients. Distal latency and velocity of the sural and posterior tibial nerves were significantly affected (p < 0.01) compared with control values. These results indicate possible motor-sensory neurotoxicity involving the lower limbs due to long-term metronidazole therapy.
