The new anticancer agent lonidamine has been recently revisited for the treatment of various solid tumors, due to its peculiar and unusual mechanism of action (ie, interference with energy metabolism of tumor cells, morphologically displayed by the appearance of "condensed mitochondria"). First generation trials have in fact demonstrated therapeutic activity and an unusual toxicity profile. Lonidamine is devoid of conventional side effects induced by antiproliferative agents (ie, myelosuppression, stomatitis, cystitis, alopecia, renal, hepatic, and cardiac toxicity). No serious or life-threatening adverse reactions have been recorded even over long term treatment periods. Given as a single agent (in daily doses ranging between 300 and 900 mg) lonidamine induces the following side effects: myalgia, testicular pain, asthenia, ototoxicity, nausea and vomiting, gastric pain, and drowsiness. Hyperesthesia and photophobia have also been reported. In combination with radiotherapy (in oral daily doses ranging between 300 and 450 mg) lonidamine was well tolerated, without any reported evidence of additional toxicity. When associated with cytotoxic agents no enhanced toxicity was observed. In particular, myelosuppression and other conventional nonhematological adverse reactions were never greater than would be expected with chemotherapy alone. The same applies to toxicity and tolerance of lonidamine when used concurrently with hypertermia. The data collected from large series of cancer patients treated with this new agent show that lonidamine is a safe drug whether used alone or in combination with other effective anticancer treatments. The reported therapeutic efficacy and the peculiar toxic profile make lonidamine an interesting new drug for future clinical trials.

Fourteen previously treated patients with relapsed or refractory poor-prognosis non-Hodgkin's lymphoma were given chemotherapy regimens containing high doses of cytosine arabinoside alone (seven patients) or with an anthracycline or amsacrine (seven patients). Five patients achieved a complete remission and two patients had a partial remission. The durations of remission, however, were short (median, 3 months; range, 2-6 months). Toxicities included conjunctivitis, photophobia, stomatitis, dermatitis, cerebellar dysfunction, diarrhea, nausea, vomiting, liver dysfunction, and severe myelosuppression. Recovery of an absolute granulocyte count greater than 500/microliter and an untransfused platelet count greater than 20,000/microliter required a median of 31 (range, 28-35) and 30 (range, 27-43) days, respectively. Six patients died with recurrent or residual disease before bone marrow recovery. Younger age, good performance status, and a previous complete remission were predictive of a good response. High-dose cytosine arabinoside has major myelotoxicity but significant activity in some patients with poor-prognosis non-Hodgkin's lymphoma.

Thirty-six patients with measurable or evaluable advanced soft tissue sarcoma were entered in a phase II trial with PALA. Among the 27 evaluable patients, 15 were men, the median age was 55 yr (16-69) and the median performance status (Karnofsky) was 80 (50-100). Most patients had leiomyosarcoma (8), liposarcoma (3), neurofibrosarcoma (3), synovial cell sarcoma (3), or undifferentiated sarcoma (3). Indicator lesions consisted essentially of lung metastases (21) and/or soft tissue lesions (14). All patients had received prior chemotherapy with 1-5 regimens and 6 had achieved objective response with these previous treatments. PALA was given as a 60-min i.v. infusion at a daily dose of 2.5 g/m2 for two consecutive days. Courses were repeated every two weeks. A median number of 3 courses (2-17) were administered. Partial remission (greater than 50%) was obtained in one patient with a liposarcoma who had also responded to prior combination chemotherapy. This single response to PALA lasted 6 weeks from initiation of therapy. Four patients had unchanged disease after 6+ courses of PALA and 22 had progressive disease. Toxic effects were generally mild to moderate and included cutaneous toxicity (17), diarrhea (14), stomatitis (13), ocular manifestations, consisting of conjunctivitis, corneal ulceration and/or photophobia (11), nausea and vomiting (6) and, possibly, seizures (2). There was no evidence of drug-related myelosuppression. It is concluded that PALA given at the dose schedule selected for this trial has no significant antitumor activity in advanced soft tissue sarcoma previously treated with chemotherapy.

In this study, pathological, serological and virological examinations were performed on 15 sheep from a flock of 250 sheep and lambs that suffer from simultaneous naturally occurring BTV, PPRV and SPV outbreaks. SPV was diagnosed macroscopically and histopathologically, BTV was diagnosed by ELISA, and PPRV was diagnosed pathologically and by ELISA. Clinically fever, diarrhea, depression, polypnea, conjunctivitis, lacrimation, rhinitis, erosive stomatitis, edema of eyelids, photophobia, cutaneous eruption with erythematous areas especially noticeable in wool-free parts of the body and axilla lesions evolving into papules were observed. At necropsy, the most effected organs were lungs and gut. Subepicardial hemorrhages were also commonly seen. While typical pox lesions were observed in some lambs, usually fibrinous pleuropneumonia was more prominent lung lesion. SPV and PPRV lesions were seen at the histopathological examination of the lesioned tissues, BT lesions were mild than SPV and PPRV microscopically. Serum and leukocyte samples of 15 animals were examined for PPRV and BTV by ELISA; 5 samples were positive for PPRV and 6 BTV, 4 were positive for both PPRV and BTV simultaneously. One hundred animals died, most were lambs. Mortality rates were 100% in lambs and 80% in the herd.
