For the purpose of evaluating the efficiency of an unspecific immunostimulation in acute leukaemias the results of treatment obtained from two groups of patients (a total of 55 children) were compiled. In the first group an unspecific immunostimulation with vaccination (BCG, diphtheria-tetanus-pertussis, measles) could be observed after the induction of remission during a cytostatic maintenance therapy. In the second group a polychemical therapy and the CNS-irradiation was applied according to the treatment scheme developed by the working team of Donald Pinkel. The group of patients treated with unspecific immunostimulation involved a high percentage of surviving children. In total there was no essential difference between the treatment results of both schemes of therapy during our period of observation. As before, the treatment of hyperleukocytic forms of leukaemias will cause particular difficulties.

Thymus of (C57Bl/6 x DBA/2) F1 mice was examined histologically, histochemically and ultrastructurally, seven days after intravenous injection of BCG, pertussis vaccine, lipopolysaccharide or human gamma globulin, or intraperitoneal injection of complete or incomplete Freund's adjuvants or of phytohemagglutinin. Only BCG induced a marked increase of the secretory activity of the thymic epithelium at all histological sites (cortex, corticomedullary junction and medullar). Only with this adjuvant was the epithelial hyperplasia associated with marked mitotic activity and high percentage of cells with cytoplasmic pyroninophilia among cortical lymphoid cells. The other substances tested produced different changes in the thymic epithelial cells according to the histologic zones. These results suggest that the epithelial cells of the cortex, the corticomedullary junction and the medulla respond differently to the agents tested and that the action of these substances upon thymus-dependent lymphoid cells may be indirect perhaps involving factors secreted by the epithelial cells.

A new and sensitive assay procedure for studying erythrophagocytosis is described. The assay technique permits quantitation of the in vivo and in vitro effects of chemicals, hormones, and cell, or microbrial products, on the level of phagocytic activation of glass-adherent cells. The effect of intraperitoneal injection of BCG, Zymosan, Vitamin A, B. pertussis, cortisone, estrone, and thioglycollate on phagocytic activation of peritoneal exudate cells harvested from two days up to 28 days following drug injection was examined by this assay. Erythrophagocytosis was compared to the effect of "activated" spleen cells on tritiated thymidine uptake of a tumor target cell suspension.

Enhancing and suppressing effects of microbial adjuvants were studied in female mice of the C3H/He, AKR and SL strains. Propionibacterium acnes, Bordetella pertussis, BCG and yeast cell wall (YCW) were chosen as adjuvants. As antigens, we chose hamster erythrocytes (HRBC) which proved to be a weak antigen for mice. Adjuvants were given on day --7, day 0 or day 3, and HRBC were injected on day 0. The results were as follows. 1) P. acnes facilitated IgM and IgG antibody production in AKR mice and suppressed IgM antibody production in SL mice, when given on day --7. When P. acnes was given on day 0, they suppressed IgM antibody production in all of the strains used. 2) When B. pertussis was given on day 0, it exhibited enhancing effects on IgG antibody production in all of the strains and a suppressing effect on IgM antibody production in SL mice. 3) BCG suppressed IgM antibody production in all strains when given on day 0. 4) YCW showed no influence on antibody production in any combination used in this work. 5) SL mice were very sensitive to suppressing effects by adjuvants. Strain differences in the expression of enhancing and suppressing effects by adjuvants appear to be under some control independent of antigen-specific immune response genes.

Whether differences in foetoplacental weight and post-implantation mortality in rodents are secondary to heterosis and inbreeding depression or antigenic differences between mother and foetus has been a continuing controversy. To determine whether non-specific depression or stimulation of the maternal immune system affects the success of the foetoplacental allograft, groups of virgin Fischer (Ag-B1) females of similar age and weight mated with DA (Ag-B4) males were treated with daily intraperitoneal injections of: (a) saline, (b) methylprednisolone (MP), 1-0 mg/kg, (c) cyclophosphamide (CY), 3.0 mg/kg, or (d) azathioprine (AZ), 3.0 mg/kg; or they were injected intraperitoneally on the fifth day of gestation with: (a) B. pertussis, 1.0 ml, (b) C. parvum, 0.2 ml, or (c) BCG, 0.1 ml. None of the immunostimulating agents were detrimental to the progeny, but the immunosupprissive drugs caused an increased percentage of foetal deaths and foetoplacental growth retardation. The reduced foetal and placental size induced by CY or AZ could be partially blocked by simultaneous maternal treatment with BCG. Analysis of mean maternal weight gain, spleen weight assays, changes in the lymph nodes draining the uterus and comparison of data from non-pregnant animals and syngeneic pregnancies treated with these agents suggest that immunosuppressive drugs reduce foetal survival rates and produce foetoplacental growth retardation via a combination of immunological and cytotoxic mechanisms.

In a controlled field-trial in infants in the Philippines, a two-dose schedule with an interval of 6 months between injections using a concentrated adsorbed DPT-vaccine was evaluated. The serologic response against the three components in the vaccine was satisfactory, whereas the side-effects in the concentrated vaccine group did not differ from those observed in a control DPT group. After two injections, the coverage percentage with DPT-vaccine was shown to be higher than 70%. Two implications of the introduction of the two-dose DPT-immunization schedule are discussed, i.e. (a) the possibility of using it as the nucleus of a complete schedule including immunization against poliomyelitis, BCG, smallpox and measles, and (b) the consequences which the interval of 6 months might have on the epidemiological spread of B. pertussis infections.

Cell-mediated immune response (CMI) and several aspects of humoral immune status and response were measured and related to nutritional status in preschool children in north India. CMI was measured by means of postvaccinal (BCG) tuberculin sensitivity and leucocytic blast cell transformation. Humoral immune response was measured by means of tetanus antibody production following vaccination with diphtheria-pertussis-tetanus vaccine. Immunoglobulins A, G, and M and complement (C(3)) were also determined. CMI, serum IgA, and C(3) were found to be directly correlated with weight-for-age status.

The effect, hazards and risk of vaccinations may be calculated by means of special formulas which determine the value for N, Q and D. The formula for N considers the question whether a vaccination is effective, necessary and valuable and may be recommended on epidemiological grounds. Q considers the individual risk (i. e. relation between total risk of unvaccinated and vaccinated persons) and D the yearly difference in risks between unvaccinated and vaccinated members of a community. If p stands for protection rate of a vaccination, t = time for which the vaccination effect is lasting, R = complications of disease under study in a community in which vaccinations against this disease are not in use and r = comparable complications of vaccination, the following formulas are applicable: (see article) A vaccination may be recommended if N and Q greater than 1 and the value for D is positiv. Application of these formulas to special vaccinations lead to the following conclusions: In case of BCG, measles and poliomyelitis (oral vaccination) the above mentioned values exceed at least 10(1)-10(2) (N), 4-5 (Q) or are highly positiv (D). These vaccinations-if performed correctly-are considered valuable and highly recommendable. Vaccination against pertussis is not recommendable beyond the second year of life. According to the present epidemiologic situation in Austria this vaccination is still rectified in children under 2 years. However, values for N, Q and D are near border-line and should be yearly evaluated. Smallpox vaccination in Europe is still recommendable. Similarly, continuous reevaluations are necessary due to low values of N, Q and D. On the other hand, vaccination against tetanus is available and vaccination against influenza may be recommended.

A retrospective study of 1984-89 records in the Department of Control and Surveillance of Diseases at the Directorate of Health Affairs in Al-Hassa, Saudi Arabia, aimed to determine the effect of vaccination coverage in the first year of life on the trend of target diseases of the expanded program if immunization (EPI), begun in February 1987, and to determine the effect this program had on vaccination coverage. From 1984-89, vaccination coverage of the first year of life increased significantly for BCG (88.6 vs. 97.8%); oral polio vaccine (86 vs. 96%); diphtheria, pertussis, and tetanus (DPT) vaccine (85.8 vs. 95.2%); and measles vaccine (72.6 vs. 89.2%) (p .01 for all vaccines). Average vaccination coverage per year in the first year of life against the EPI target diseases rose from 83-94.7% (p .01). The number of cases of pulmonary tuberculosis (TB) and measles decreased steadily during the same period (97-56 and 502-84, respectively). All the diphtheria cases occurred in 1985 (6 cases). There were no pertussis cases in 1985, 1987, or 1988. 14 pertussis cases occurred in 1984, 4 in 1986, and 2 in 1989. TB cases fell 42.3%,measles cases 83.3%, and pertussis 34.6%. Neither poliomyelitis nor neonatal tetanus afflicted any infants in Al-Hassa during the same period. A negative correlation existed between BCG, DPT, and measles vaccine and reported cases of respective diseases. It was significant for measles vaccine (p = .043). In fact, the number of reported cases of measles fell by 25 cases for every 1% improvement in measles vaccination coverage. Most infants (78.5-80.2%) were vaccinated against the EPI target diseases at primary health care centers or at Ministry of Health hospitals. The remaining 19.8-21.5% of infants received the EPI vaccines at health facilities of the Arabian American Oil Company, the National Guard, and the private sector. These findings suggested that implementation of the primary health care program, EPI, improved vaccination coverage and reduced the number of cases of EPI target diseases in Al-Hassa.

The Integrated Child Development Services (ICDS) programme was launched by the Indian government in October 1975 to provide a package of health, nutrition and informal educational services to mothers and children. In 1988 we studied the impact of ICDS on the immunization coverage of children aged 12-24 months and of mothers of infants in 19 rural, 8 tribal, and 9 urban ICDS projects that had been operational for more than 5 years. Complete coverage with BCG, diphtheria-pertussis-tetanus (DPT) and poliomyelitis vaccines was recorded for 65%, 63%, and 64% of children, respectively, in the ICDS population. By comparison, the coverage in the non-ICDS group was only 22% for BCG, 28% for DPT, and 27% for poliomyelitis. Complete immunization with tetanus toxoid was recorded for 68% of the mothers in the ICDS group and for 40% in the non-ICDS group. Coverage was greater in the urban and lower in the tribal projects. Scheduled castes, scheduled tribes, backward communities, and minorities (groups that have a high priority for social services) had immunization coverages in ICDS projects that were similar to those of higher castes.
