    Notes: Abstract Incidence and mortality of AIDS patients have significantly declined in the developed countries due to the very active anti-HIV combination therapy available today. Because of the prolongation of the survival expectancy of these patients, other non-AIDS defining tumours have been recently reported in several cohort studies with increased frequency. We want to report the clinico-pathological features and the outcome of 39 patients with lung cancer and HIV infection, collected by the Italian Cooperative Group on AIDS and Tumors (GICAT) between 1986 and December 1997. As a control group, we decided to evaluate patients, less than 60 years of age, with lung cancer but without HIV infection seen at the CRO, Aviano, during 1995 and 1996. The median age of the study group patients was 38 years (range 28–58) and 90% of them were males. Sixty-nine percent of patients were intravenous drug users and HIV infection was asyntomatic in 41% of patients. NSCLC was observed in 78% of patients, SCLC in 13% and mesothelioma in 8%. Among NSCLC, adenocarcinoma was the most frequently observed histological subtype (48%). No differences were found as regards the stage of disease at diagnosis and the histologic subtype in comparison with the control group. The median overall survival was significantly shorter for patients with HIV infection when compared to that of the control group (5 months vs. 10 months, P 〈 0.0001). In conclusion, the outcome of patients with SNCLC and HIV infection seems worse than that of the general population, suggesting a synergistic and/or addictive adverse effect of HIV on the outcome of lung cancer.

    Description / Table of Contents: Zusammenfassung Amphotericin B ist die einzige antimykotisch wirkende Substanz, die trotz ihrer dosislimitierenden Toxizität intravenös gegeben werden kann, wenn eine aggressive Behandlung erforderlich ist. In der Absicht, die medikamentös-toxischen Nebenwirkungen bei gleichbleibender therapeutischer Wirksamkeit zu reduzieren, wurden neue Formulierungen von Amphotericin B entwickelt. Am erfolgversprechendsten erwies sich bisher die Verwendung von Lipiden als Trägersubstanzen. Bis jetzt wurden drei lipid-gebundene Amphotericin-B-Formulierungen von pharmazeutischen Unternehemen entwickelt, die zur Zeit klinisch geprüft werden. Es werden Angaben zur Wirksamkeit und Verträglichkeit dieser Derivate bei Tieren und Menschen zusammenfassend dargestellt, insbesondere unter Berücksichtigung der Kryptokokken-Infektion. Die Autoren berichten über ihre Erfahrungen mit einer kleinen unilamellären liposomalen Amphotericin-B-Formulierung (AmBisome™) in der Primärtherapie der Kryptokokkose. Neun Patienten mit AIDS und Kryptokokken-Infektion (sieben Patienten hiervon mit Meningitis) erhielten AmBisome™ (3 mg/kg/Tag) über 3–6 Wochen. Vollständige Remissionen wurden bei sechs Patienten erreicht, eine deutliche Besserung bei zwei Patienten. Bei einem Patienten versagte die Therapie. AmBisome™ wurde gut vertragen und verkürzte das Zeitintervall bis zur klinischen und mykologischen Besserung, was eine weitere Verbesserung in der Therapie der Kryptokokkose bedeuten kann.
    Notes: Summary Amphotericin B is the only antifungal drug which, despite its dose-limiting toxicity, can be given intravenously when an aggressive treatment is required. In an attempt to reduce the drug toxicity while retaining its therapeutic efficacy, new formulations of amphotericin B have been developed. The most promising have employed lipid vehicles such as liposomes. Three lipid-based amphotericin B formulations have been developed by pharmaceutical companies and are under active clinical investigation. Efficacy and safety data of these derivatives in animals and humans are reviewed, with particular concern to cryptococcal infection. The authors' experience with a small unilamellar liposomal amphotericin B formulation, AmBisome, in the primary therapy of cryptococcosis is reported. Nine AIDS patients affected with cryptococcosis, seven of whom had meningitis, were given AmBisome (3 mg/kg/day) for 3–6 weeks. Complete response was obtained in six patients, marked improvement in two, and failure in one. AmBisome was well tolerated and shortened the time to clinical and mycological response suggesting a further improvement in the management of cryptococcosis in AIDS patients.

    Description / Table of Contents: Sommario Sono riportiti i risultati delle titolazioni anticorporali verso i virus della parotite, della rosolia, Sendai ed herpes simplex nel siero di 176 pazienti affetti da Sclerosi Multipla e di 150 soggetti sani di controllo, nonché nel liquor di 48 dei malati. In precedenza negli stessi gruppi di soggetti erano stati studiati gli anticorpi antimorbillo. Differenze tra i malati ed i controlli sono state riscontrate solo per la prevalenza nel siero degli anticorpi inibenti l'emoagglutinazione antiparotite e degli anticorpi fissanti il complemento verso l'herpes simplex. Va sottolineato che, al contrario di quanto si è verificato per il virus della parotite, solo i pazienti sottoposti a terapia con farmaci immunodepressivi presentavano una prevalenza degli anticorpi fissanti il complemento verso l'herpes simplex statisticamente maggiore dei controlli. Sulla base delle presenti e di precedenti osservazioni, sembra che il morbillo in primo luogo e la parotite siano i virus per i quali esistono maggiori evidenze di un coinvolgimento nell'eziopatogenesi della Sclerosi Multipla.
    Notes: Abstract The sera of 176 MS patients and of 150 healthy adult controls were assayed for antibodies against mumps, rubella, Sendai and herpes simplex viruses, a higher prevalence of measles c.f.a. having already been demonstrated in the MS patients. The CSF of 48 of the MS patients were subjected to the same tests. The patients differed from the controls in a higher prevalence of h.i.a. to mumps and of c.f.a. to herpes simplex. For the latter, but not for the former, the prevalence was statistically higher only in patients treated with immunosuppressants. To date measles seems to be the most seriously incriminated virus in the etiopathogenesis of MS, mumps ranking second.
