A rare occurrence of invasive pulmonary aspergillosis complicates influenza pneumonia in a previously healthy adult. Five other similar cases are reported in the literature. Both transient depression of cell-mediated immunity and loss of ciliary function in the tracheobronchial tree occurs during acute influenzal illness and may predispose to fungal superinfection. Early diagnosis and treatment of opportunistic Aspergillus infection complicating influenza is mandatory in view of the high mortality associated with this complication.

Eight previously treated and four untreated patients with B cell chronic lymphocytic leukemia (CLL) received 20 X 10(6) U/m2 recombinant leukocyte interferon clone A (rIFN-alpha A) intramuscularly three times a week for 8 weeks. None of the eight patients who had received prior chemotherapy exhibited objective evidence of tumor regression. Two of the four previously untreated patients responded with transient (90%) decreases in absolute lymphocyte counts lasting for 2 and 7 months. Toxicity was moderate, with all patients experiencing a flu-like syndrome requiring a 50% dose reduction. Half of the patients exhibited anorexia, weight loss, and a drop in performance status. The two responders had normal serum immunoglobulin levels prior to treatment, whereas 80% of non-responders had depressed levels. Treatment with rIFN-alpha A was associated with a depression of nonspecific and specific humoral immunity in assays employing cryopreserved autologous pretherapy CLL cells. No consistent effects were demonstrable in cytolytic assays with purified peripheral blood T cells as effector cells, including one that utilized autologous CLL target cells. rIFN-alpha A has limited antitumor activity in B cell CLL which is restricted to untreated patients with an early stage of disease. With the assays employed it was not possible to demonstrate that rIFN-alpha A could augment autologous antitumor immunity.

I have presented a possible case of mania induced by influenza B. Some epidemic influenza viruses may be neurovirulent. These epidemics seem to be associated with postencephalitic Parkinson's disease, mania, and depression. Viral, neuroanatomic, neurophysiologic, neurochemical, pharmacologic, clinical, and epidemiologic evidence can be found to suggest a connection between the locus ceruleus, the influenza virus, and the induction of a manic psychosis.

Experimental and more limited clinical studies have suggested that influenza vaccination may depress the oxidative hepatic metabolism of various drugs and lead to drug toxicity. The alleged mechanism is the formation of interferon and the resulting decrease in cytochrome P-450 available for drug oxidation. Because of the clinical and basic science implications of these reports, we undertook to study the effects of influenza vaccine on the metabolism of three commonly used drugs: chlordiazepoxide, theophylline, and lorazepam. Our healthy male subjects were studied just before and 1 and 7 days after vaccination. As expected, lorazepam metabolism, which proceeds by glucuronidation and not oxidation, was not altered by vaccination. Surprisingly, however, the oxidation of chlordiazepoxide was also not depressed by the vaccine. Theophylline oxidation, which proceeds primarily by microsomal oxidation (demethylation), was significantly decreased 1 day, but not 7 days, after vaccination. Serum alpha-interferon levels rose after vaccination for only about 8 hours, and levels of gamma-interferon rose to about 500 IU/ml at 24 hours, peaked at 72 hours, and returned to normal by 100 hours after dosing. It appeared that the higher the theophylline clearance before vaccination, the greater the degree of clearance depression after vaccination. Thus the inhibition of drug oxidation after influenza vaccination is selective and each drug should be studied individually. The degree of depression of theophylline clearance is small and transient and appears to be greater in subjects with higher prevaccination clearance.

From April to August, 1981, 15 cases of perinatal listeriosis were seen in Halifax, Nova Scotia, Canada. Nine of the 15 mothers presented with 'flu-like' symptoms, 3 had symptoms of an upper respiratory infection and 2 a history of fever alone. During labor 11 mothers had fevers greater than 38 degrees C and 9 had stained amniotic fluid. Twelve delivered prematurely. Among the 15 infants the most common clinical features were perinatal depression, respiratory distress, fever, hematologic abnormalities and rash. There were 7 deaths (case fatality rate of 46.7%). A transplacental route of infection for the fetus was suggested by the signs of systemic illness in most mothers, the lack of positive maternal vaginal cultures and evidence of chorioamnionitis, premature labor, severe fetal disease and intrauterine death prior to membrane rupture. The delivery of healthy infants to two mothers who had received antepartum treatment for listeriosis suggests that earlier recognition and treatment of maternal disease will improve perinatal outcome.

The effect on respiratory burst of murine spleen cells after in vitro exposure to influenza virus, subunits, or subunits conjugated to muramyl dipeptide (MDP) was studied by luminol-dependent chemiluminescence (CL) in response to stimulation by zymosan. CL induced by infectious influenza A virus was depressed but could be elevated to normal levels when MDP was added together with a low, but not with a high, dose of the virus. Profound depression of CL was induced by high doses of influenza A/Brazil, A/Bangkok, and B/Singapore subunits. The same amounts of viral subunits conjugated to MDP restored or even enhanced the CL responses of spleen cells from BALB/c and C57BL/6 mice. Splenic cells from BALB/c mice generated higher levels of CL than did cells from C57BL/6 mice.

When ten cats were infected orally with undiluted or a 10(-1) dilution of virulent feline infectious enteritis (panleucopaenia) virus, all developed severe leucopaenia followed by the development of demonstrable antibody, but none died. Eighteen of 29 cats given a 10(-2) dilution of virus died of the disease. Three of the survivors had white blood cell counts of less than 4000 and three had counts between 4000 and 6000 cells. Although the remaining five animals never had individual counts of less than 6000 cells, the geometric means of these counts showed that a marked depression in the leucocyte counts had occurred. All surviving cats developed antibody.Among the ten cats dosed with either 10(-3) or 10(-4) dilution of virus, four died of feline infectious enteritis and three developed antibody after falls in the leucocyte counts. It is suspected that low dilutions of feline infectious enteritis virulent virus in cats produce a phenomenon similar to that reported by von Magnus (1954) with influenza virus in eggs.Leucopaenia is commonly defined as less than 4000 white blood cells/mm.(3) of blood. Counts lower than this are usual in cats which either die of the disease or have received large doses of virus; they are less common in cats surviving after administration of diluted virus. Challenge of cats with pre-existing antibody did not provoke a depression in the leucocyte counts.

Susceptibility of eight strains of influenza A and B viruses to interferon and to poly(I) . poly(C) were determined by the plaque reduction method. All strains tested were slightly less susceptible than vesicular stomatitis virus (VSV) in an established line of canine kidney (MDCK) cells. The 50% plaque depression doses (PD50) of poly(I) . poly(C) for influenza A and B viruses were as high as 3.0- to 4.5-fold and 6- to 18-fold that for VSV, respectively. The amounts of interferon required to inhibit plaque formation of influenza A and B viruses by 50% were 3.0-6.2 and 7.3-15.2 units/ml, respectively. The ratio of PD50 of poly(I) . poly(C) for each strain of influenza viruses tested to that for VSV in chick embryo cells was almost the same as in MDCK cells. Furthermore, in chick embryo cells, the strains of influenza virus tested were demonstrated to be much more susceptible to poly(I) . poly(C) than both Newcastle disease virus and vaccinia virus. It is suggested that influenza viruses may be relatively susceptible to interferon and to poly(I) . poly(C).

The coordination compound cis-dichlorodiammineplatinum(II) (cis-DDP) was shown by Rosenberg et al. (17) to exhibit antitumour activity. Several authors have indicated limited virustatic properties of cis-DDP against bacterial, oncogenic, avipox and paramyxo viruses. In our investigations, cis-DDP significantly showed an antiviral action in vitro against enveloped DNA and RNA viruses, such as vaccinia, pseudorabies, herpes simplex type 1, Newcastle disease, influenza A/fowl plague, influenza A/Victoria 3/75, influenza A/Jena 48/78, influenza B/Johannesburg and vesicular stomatitis viruses. Out of the group of nonenveloped viruses, adenovirus type 4 and 5 were inhibited, whereas no inhibition against naked cardiovirus Mengo could be estimated. The antiviral action was proved against extracellular virus by dialysis experiments with vaccinia virus and also during the replication cycles of enveloped viruses. In trials with cell-free viruses the plaque reduction of all sensitive viruses mentioned above amounted to 100 per cent in comparison to the untreated controls caused by virus inactivation with loss of infectivity in contact with several concentrations of cis-DDP. On the other hand, the addition of the compound for one hour only immediately after infection or up to 8 hrs later produced a complete depression of further multiplication of vaccinia virus. Likewise, the replication of influenza virus A/FPV or VSV was inhibited whereas the multiplication of adenoviruses was not influenced in a comparable manner.

In September 1980, an outbreak of febrile respiratory disease was observed in a herd of sows (1-2 years of age) in Ehime Prefecture, Japan. Most of the swine showed clinical signs of disease such as depression, anorexia, fever, nasal discharge, and cough. A hemagglutinating agent was isolated from a nasal swab from one of the diseased pigs. By cross-hemagglutination-inhibition and neuraminidase-inhibition tests with antisera to influenza viruses of swine origin, the isolate was identified as an influenza A virus of the H1N2 (former designation, Hsw1N2) subtype, and designated A/swine/Ehime/1/80 (H1N2). Significant antibody rises against the surface antigens of the isolate were found in convalescent swine sera. The distribution of antibody against H1N2 virus in swine sera in Ehime Prefecture was examined. Seven (8%) of 93 sera collected after the outbreak (in 1981) showed antibodies to only H1 and N2 antigens but none of the sera before the outbreak contained such antibodies, indicating that H1N2 virus had been restricted prevalent among swine but was not wide-spread until 1981.
