Lomustine, vindesine and bleomycin (LVB) used in the treatment of relapsed advanced Hodgkin's disease. A prospective study on behalf of the East of Scotland and Newcastle Lymphoma Group (ESNLG).

Sixty-three patients with relapsed advanced Hodgkin's disease were treated with lomustine (CCNU), vindesine and bleomycin (LVB). Age range was 17-72 years, with 38 males and 25 females. Thirty patients achieved complete remission (CR) with a median duration of 24+ months (range 3-55). Nineteen continue in unmaintained CR. CR rates were highest for those patients who relapsed greater than 6 months after first line treatment and for those at second or subsequent relapse. CR rates were higher in those with nodal only relapse. Twenty-seven patients were non-responders and six were partial responders. These 33 patients were subsequently changed to alternative chemotherapeutic regimes and 26 failed to respond to any therapy and have since died. Only one patient is in unmaintained complete remission. The regimen was well tolerated by patients, and easy to administer. It produced no serious episodes of toxicity. We conclude that LVB is of value in the management of relapsed advanced Hodgkin's disease especially in chronic relapsing patients, and where relapse occurs greater than 6 months after the first line treatment. We are presently unsure whether it offers any advantage over reintroduction of first line treatment in the latter group.

Interactions between viscerotropic velogenic Newcastle diseases virus and pet birds of six species. I. Clinical and serologic responses, and viral excretion.

Clinical and serologic responses to a psittacine isolate of viscerotropic velogenic Newcastle disease virus (VVNDV) were evaluated in pet birds of six species: budgerigar, yellow-headed Amazon parrot, halfmoon conure, lesser hill mynah, black-headed nun, canary. The clinical response was most marked in the budgerigars, parrots, and conures, and only minimal in the nuns. Between post-exposure days (PED) 3 and 5 some birds developed ruffled plumage, conjunctivitis, and central nervous system dysfunction: ataxia, wing tremors, paralysis of the extremities, and tremors of the head accompanied by nodding and jerking. Mortality by PED 203 was 55% (29/52) in the halfmoon conures, 22% (23/105) in budgerigars, 29% (12/42) in parrots, and 21% (15/71) in nuns. The only clinical signs in canaries and mynahs were progressive death losses, respectively 25% (33/132) and 21% (10/48). The visceral lesions common in chickens with VVNDV were not observed in these six species. Canaries rapidly eliminated Newcastle disease virus (NDV), whereas it was detected for protracted periods in the oral and cloacal secretions of the other five species (for more than a year in parrots). Serologic evaluation by the hemagglutination-inhibition and neutralization tests also indicated prolonged NDV infections in 5 of the 6 species. The seroconversion rate observed in canaries was minimal (13%).
