Five infants with pneumococcal sepsis presented with respiratory distress and clinical signs of infection in the first day of life. Although there was no apparent epidemiological relationship among the patients, four of the five were seen within a 12-month period. Pneumonia, prolonged rupture of fetal membranes, and prematurity were features in these patients. Three infants died, two within 12 hours of diagnosis. Streptococcus pneumoniae was isolated from the vagina of three of the mothers; in two, the serotype was identical to that recovered from their infants. Clinical features of neonatal pneumococcal sepsis are similar to those of early-onset group B streptococcal infection. Like the group B Streptococcus, S. pneumoniae acquired from the maternal vagina is a potential life-threatening pathogen in the newborn period.

Cold-insoluble protein complexes (cryoprecipitates) can be found in the serum in a variety of infectious diseases. We studied serum cryoprecipitates isolated from three patients with pneumococcal pneumonia by counterimmunoelectrophoresis (CEP) and immunofluorescent technics for the presence of immune complexes. The cryoprecipitates and supernatant serum were tested for pneumococcal capsular polysaccharide (PCP) by CEP at 37 C and 56 C with the appropriate controls. Antibodies against PCP in the cryoprecipitates and the supernatant serum were detected as follows. Streptococcus pneumoniae from each case was fixed onto slides. The slides were incubated with each cryoprecipitate and supernatant serum at 37 C, and further incubated with fluorescein isothiocyanate-conjugated antisera to human IgG, IgM, and IgA. The slides were examined with an immunofluorescent microscope. PCP was demonstrated in all of the cryoprecipitates. IgG antibodies against PCP were detected in all of the cryoprecipitates, while IgM antibodies were detected in Cases 1 and 2, and IgA antibodies in Case 1 only. Complement components of C3 and C4 also were demonstrated in the cryoprecipitates by CEP. These findings suggest that some patients with pneumococcal pneumonia have cryoprecipitable-immune complexes consisting of PCP and its antibodies.

An etiologic classification of acute pneumonia was presented and the relative importance of some of the causative agents was briefly reviewed. The early developments of the therapy of pneumococcal pneumonia with type-specific antisera, sulfonamide drugs, and antimicrobial drugs were reviewed, mostly from the experiences of the author at Boston City Hospital. Changes in the occurrence and relative importance of the pneumococcus as a cause of infections associated with bacteremia, empyema, and meningitis were demonstrated, based on cases observed at Boston City Hospital during 12 selected years between 1935 and 1972. These findings, among others, indicate that the pneumococcus is still one of the most important causes of serious bacterial infections and of mortality from such infections, particularly in the elderly. Some possible indications for polyvalent pneumococcal capsular polysaccharide vaccine were discussed, and the need for further extensive clinical and field trials to demonstrate its range of effectiveness was stressed.

207 patients of a geriatric department were immunized against influenza with either tween-ether-split-vaccine or subunit-vaccine in a double blind study. For 6 months the following data were daily registered: rest in bed, fever over 38,5 degrees C, rhinitis, laryngopharingitis, bronchitis, pneumonia, enteritis, medication with antibiotics or chemotherapeutics. In cases with fever over 38,5 degrees C blood tests were taken for serological examination. The immune response against influenza A was excellent in both groups, the titer was higher in the subunit group, only one patient showed influenza infection. The immune response against the type B Hongkong was not satisfactory in both groups. The clinical data showed a significant lower incidence of rhinitis, laryngopharingitis and bronchitis in the group immunized with the tween-ether-split-vaccine. This effect was more distinct within the first 3 months after the immunization than within the second 3 months.

Thirty-seven patients with advanced Hodgkin's disease have been treated for greater than or equal to 3 months with a protocol consisting of alternate monthly courses of MOPP (mechlorethamine, Oncovin [vincristine], procarbazine, and prednisone) and ABDV (adriamycin, bleomycin, DTIC, and vinblastine) with local radiotherapy (RT) to areas of originally bulky disease. This therapy produced CR in 19 of 19 previously untreated patients (100%), eight of nine previously treated with RT (89%), and six of nine previously treated with RT and MOPP (67%). The remaining patients are all PRs tending toward CR status. The median time to CR was 3.0 months. The median time in remission to date for the previously untreated patients is 8+ months (2+-14+). After an induction period of eight cycles of chemotherapy patients are maintained on alternate-month treatment continuing the alternating sequence. During this phase three patients have experienced reappearance of disease (one recurrence, one possible second primary lymphoma, and one recurrence in a patient whose original diagnosis is in doubt). The regimen has been well tolerated. All patients were treated as outpatients. Alopecia and neurotoxicity were mild and myelosuppression was moderate. Clinically significant cardiopulmonary toxicity has been limited to mild radiation pneumonitis in one patient and bleomycin pneumonitis which cleared during prednisone in a second patient.

An antigenically distinct adenovirus is described which was isolated in March 1973 from the lungs and kidney of a 61-year-old woman who died of diffuse interstitial adenovirus pneumonia 55 days after receiving a cadaveric renal allograft. Complement fixation, hemagglutination inhibition, and serum neutralization tests on sequential serum specimens from the patient confirmed that the adenovirus infection occurred in coincidence with her clinical illness and failed to document concomitant infection by any other common respiratory agent. Pathological and virological findings indicated that the pneumonia was only one manifestation of a disseminated adenovirus infection, the source of which may have been a latent infection pre-existing in the donor kidney. The adenovirus, purified by terminal dilution and plaque procedures, has antigenic, morphological, biological, biophysical, host susceptibility, and hemagglutinating properties characteristic of adenovirus group 1A. Buoyant densities in CsCl are 1.340 g/ml for the virion, 1,300 g/ml for the group complement-fixing (hexon) antigen, and 1.290 g/ml for the major soluble complete hemagglutinin (dodecon). The virus was serologically distinct from adenoviruses 1 to 34 in reciprocal serum neutralization tests with antisera to these viruses. We propose this virus as candidate adenovirus type 35 (holden).

Mediators of immediate-type hypersensitivity were studied in the sputum of patients with chronic bronchitis. The same mediators were also measured in early-onset, skin-test-positive asthmatics, in late-onset, skin-test-negative asthmatics, and in patients with bronchial carcinoma, bronchiectasis, and pneumonia. Sputum eosinophilia was a feature of bronchitics and asthmatics, whereas raised blood eosinophil levels were found only in the early-onset, skin-test-positive asthmatics. Histamine and IgE were present in considerable amounts in the sputum of bronchitics and early-onset, skin-test-positive asthmatics. Smaller amounts were found in the other groups. The sputum in all the groups contained material giving an "S.R.S (slow-reacting substance) like" induced contraction of the guinea pig ileum. "Classical" S.R.S.-A., determined by arylsulphatase IIB susceptibility, was present only in bronchitics and both types of asthmatics. Since the bronchitics were, in general, skin-test negative and had normal concentrations of circulating IgE and eosinophils, it is suggested that the findings in the sputum indicate an element of local immediate-type (type I) hypersensitivity in bronchitis although its significance for pathogenesis is not known.

A new polyvalent, cell wall extract, Pseudomonas aeruginosa vaccine (PEV-01), was evaluated by using a guinea pig model of experimental Pseudomonas pneumonia. Guinea pigs routinely developed fourfold rises in serum hemagglutinating Pseudomonas antibodies after four vaccine injections given over 2 weeks. Vaccinated animals survived an intratracheal Pseudomonas challenge (1 X 10(8) colony-forming units) significantly better (13 of 14 survived) than did a control group (5 of 14 survived) (P less than 0.01). Clearance of viable Pseudomonas from lung tissue was significantly better in vaccinees than controls at both 3 h (P less than 0.02) and 6 h (P less than 0.05) after infection. Both gross and histological examinations of lung tissue revealed less pulmonary tissue damage in vaccinated animals following Pseudomonas infection. Thus, PEV-01 Pseudomonas vaccine appears capable of eliciting a specific protective response in the guinea pig respiratory tract.

3 separate prospective controlled studies in India and Canada were conducted to determine the immunologic benefits of breastfeeding. In the Indian rural study, 35 newborn infants breastfed exclusively for at least the first 2 months of life were studied (average duration of breastfeeding, 4.8 months; range, 2.2-8.5 months), along with 35 bottlefed controls (using fresh cow's or buffalo's milk) matched as to socioeconomic status, parental education, occupation and family size. In the Canadian urban study, 30 breastfed neonates (average duration of breastfeeding, 3 to 6 months, range 2.5-5.8 months) and 30 matched bottlefed controls were similarly studied. The third study consisted of 37 infants exclusively breastfed for the first 6 weeks of life or longer; these infants had older siblings diagnosed as having an atopic disease. The controls consisted of 37 bottlefed infants who also had an older sibling with an allergic disease. In both the Indian and Canadian studies, all breastfed infants had significantly lower incidence of respiratory and diarrheal diseases and of complications such as pneumonia and dehydration (p0.001 in the Indian study; in the Canadian study, p.001 for respiratory infection and otitis media, p0.01 for diarrhea and p0.1 for dehydration) compared with bottlefed infants. In the study of infants with family history of atopy, breastfed infants had a marked reduction in the incidence of clinical atopic eczema and of recurrent allergic wheezing. High levels of serum IgE were seen in a large number of bottlefed infants, as were eosinophilia; IgE antibodies to cow's milk protein (40% of bottlefed babies); hemagglutinating antibodies (84%), and; complement activation in vivo after milk challenge. These findings support the claim that breastmilk provides immunologic benefits to the infant. They also show that 6 weeks of exclusive breastfeeding is effective in reducing the possibility of hypersensitivity and the incidence of manifest allergic disease in susceptible infants.

Acute lupus pneumonitis was the presenting manifestation of systemic lupus erythematosus in six of 12 cases in this series. The clinical picture was characterized by severe dyspnea, tachypnea, fever and arterial hypoxemia. Radiographic findings included an acinar filling pattern which was invariably found in the lower lobes and was bilateral in 10 of the cases. Studies failed to reveal evidence of infection as a cause of the acute pulmonary infiltrates. All patients were treated with oxygen and corticosteroids; seven received azathioprine. Six patients survived and are clinically well 14 months to four years following their acute illness. Three of these patients have residual interstitial infiltrates with persistent pulmonary function test abnormalities indicating progression to chronic interstitial pneumonitis. Histologic sections of the lungs available from four patients revealed hyaline membranes and interstitial edema (four cases), acute alveolitis (two cases), arteriolar thrombosis (one case) and a prominent lymphocytic interstitial pneumonitis with organizing bronchiolitis (one case).
