Abstract
Hepatitis C virus (HCV) infection becomes chronic in more than 70% of patients, leading to end stage liver disease in about 20-30% of these patients. Apart from the virus itself, host factors that modulate the immune response are likely to be involved in determining the outcome of HCV infection. Studies on the association of human leucocyte antigens (HLAs) and HCV infection have shown inconsistent results. Selection of patient subgroups may be crucial. However, any association relevant to HCV disease progression will become evident, especially in those patients with end stage liver disease. Therefore, we analysed the phenotype frequencies of HLA antigens in two groups of 69 and 39 patients with HCV induced liver cirrhosis who had received a transplant or were awaiting liver transplantation. The first group was typed serologically and compared with 331 blood and liver donors. The second group, prospectively HLA typed by a polymerase chain reaction-sequence specific oligonucleotide (PCR-SSO) procedure for HLA-DRB and DQB alleles, was compared with another 170 PCR-SSO typed and randomly selected blood donors. Decreased frequencies for HLA-DR5 and HLA-DQ3 were found in one group of patients with HCV induced liver cirrhosis compared with the control groups. In the second analysis comparing 39 patients with end stage liver cirrhosis with blood donors, we confirmed the significant decrease in HLA-DRB1*11 and HLA-DQB1*03, which corresponded to serological HLA-DR5 and HLA-DQ3 antigens, respectively. Our results show that the presence of HLA-DRB1*11 and HLA-DQB1*03 alleles is associated with a reduced risk for the development of HCV induced end stage liver disease.

Abstract
Serum concentrations of the thrombopoiesis-enhancing cytokines thrombopoietin (TPO), erythropoietin (EPO), interleukin (IL)-6 and IL-11 were determined in 119 healthy whole-blood (WBD) and 101 platelet donors (PD) prior to donation. The 90% TPO reference interval in WBD of 64-867 pg/ml (median 163, 100% range 45-7572) was significantly higher than in PD of 56-524 (median 122, range 44-801, P = 0.004), whereas their platelet counts were lower (P < 0.001). EPO levels were not different (WBD 7.7 +/- 3.8, PD 8.0 +/- 4.9 IU/l), IL-6 and IL-11 were below the detection limit in >/=90% of cases (IL-6 < 3.2 pg/ml, IL-11 < 31.2 pg/ml). None of the cytokines correlated with platelet counts, other blood parameters, or in the PD group with the frequency of platelet donations within the last 6 months. We conclude that plateletpheresis does not lead to a lasting increase of thrombopoietic cytokines and provide reference data for potential platelet mobilization strategies with recombinant growth factors.

Abstract
Variable amounts of non-specific amplification may occur in HLA PCR-SSP typing, and this can be significantly reduced by the use of AmpliTaq Gold. In an effort to achieve an optimal balance between specificity and efficiency of the PCR amplification for both HLA alleles and the internal control, we designed a system of timed-release activity by combining two different Taq DNA polymerases. The reaction was started at a relatively low level of enzyme activity and as thermal cycling progressed more and more Ampli-Taq Gold was slowly activated for the reaction to continue. We applied this system to all routine HLA PCR-SSP typing. The number of repeat typings due to non-specific amplification and/or amplification failure of the internal control was remarkably reduced.

Abstract
48 healthy donors underwent peripheral blood stem cell (PBSC) apheresis for allogeneic transplantation beginning on day 4 of G-CSF (2 x 5 microg/kg) mobilization. In one to four (median two) large-volume mononuclear cell aphereses, a median of 55.9 x 10(9) of lymphocytes (range 21.0-109.2 x 10[9]) were collected, an amount comparable to lymphocyte numbers removed by therapeutic lymphaphereses in autoimmune diseases. Mean peripheral lymphocyte counts decreased from premobilization values of 2.31 x 10(9)/l to 1.31 x 10(9)/l at a median of 34 d (1 month) and 1.53 x 10(9)/l at a median of 327 d (11 months). The decrease in peripheral lymphocyte counts was significantly correlated with the number of lymphocytes removed and the number of aphereses. Neutrophil and platelet counts returned to normal values after 1 month whereas monocyte counts and haemoglobin concentrations were significantly decreased at 1 month but not at 11 months.

Abstract
Here we present a PCR-SSO procedure designed to simplify HLA-DR typing. We labelled 8 of a total of 16 oligonucleotide probes with digoxigenin, the others with biotin, and formed 8 pairs, each containing a digoxigenin- as well as a biotin-labelled probe. Each pair was hybridized simultaneously to one of eight dot blot membranes containing the DNA to be typed. Specific binding was detected by incubation with a mixture of the appropriate conjugates followed by sequential addition first of a chemiluminescent substrate to detect the digoxigenin-labelled probe and then a chromogenic substrate for detection of the biotin-labelled probe. With this procedure, the specific binding of two different probes to the same dot blot membrane could be evaluated, considerably reducing the labor inherent in PCR-SSO typing.

Abstract
The erythrocytes of a blood donor (P) showed an unusual pattern with anti-D sera: no agglutination with incomplete sera, and a strong agglutination with 2 out of 5 complete, monoclonal sera. These findings suggested the presence of an Rh 33, which was then confirmed in two external laboratories as the genotyp R0Har. Using anti-e sera, the titer scores of the cells of P were comparable with those of Ee cells but were only half as high as the scores of ee cells. This is consistent with a weak e in R0Har. The red cells of the donor's daughter (T) gave a positive reaction with all anti-D sera, but we observed no or only weak agglutination with several anti-e sera. It is very probable that T is also carrier of R0Har.

DRB1*08 haplotypes have not been known to carry a DRB3 gene. We have found a patient suffering from liver disease who has a novel HLA haplotype of DRB1*0801 with DRB3*0202 as established by family segregation. These two genes were confirmed by sequencing. DR8 and DR52 antigen specificities were serologically detected, indicating expression of these genes.

Abstract
OBJECTIVES Human platelet alloantigen (HPA) typing has potential clinical relevance in a variety of contexts. We can improve methods for HPA genotyping by complementing our knowledge of the DNA sequence polymorphisms of HPA genes and experience with various DNA-based HPA typing techniques. METHODS A newly available DNA polymerase, AmpliTaq Gold (Perkin Elmer), provided in an inactive state and activated by heat, makes it possible to perform a hot start polymerase chain reaction (PCR) in order to prevent nonspecific amplification during the setup of PCR. To establish a practical procedure for HPA-1, 2, 3 and 5 genotyping, we applied the AmpliTaq Gold for a hot start PCR and employed 8 pairs of published sequence-specific primers (SSP). A simple simultaneous genotyping of these 4 HPA systems could be rapidly achieved with high specificity. RESULTS The HPA gene frequencies observed in 126 randomly selected German blood donors were 0.82 and 0.18 for HPA-1a and 1b, 0.92 and 0.08 for HPA-2a and 2b, 0.63 and 0.37 for HPA-3a and 3b and 0.90 and 0.10 for HPA-5a and Sb, respectively. CONCLUSION Using our hot start PCR-SSP procedure with AmpliTaq Gold a simple, rapid and reproducible genotyping for HPA-1, 2, 3 and S systems could be achieved.

Abstract
BACKGROUND Divergent results have been reported with regard to the relationship between the course of hepatitis B virus (HBV) infection and the human leukocyte antigen (HLA) determinants. The aim of the present study was to investigate the phenotype frequencies of HLA class-I and -II alleles in Caucasians with and without HBV infection. METHODS Fifty-eight patients with persistent HBV infection (group 1), 119 patients with resolved HBV infection (group 2), and 106 patients neither infected by HBV nor vaccinated against HBV (group 3) were analyzed. All patients had end-stage renal disease. HLA class-I antigens were serologically determined. For HLA class-II typing we performed DRB1, DQA1, and DQB1 genotyping using a polymerase chain reaction-sequence-specific oligonucleotide procedure. RESULTS Compared with group 2, group 1 showed increased frequencies of HLA-B8, DR3 (P < 0.05), A30, DQA1*0501 (P < 0.01), and a decreased frequency of HLA-B12 (P < 0.05). Decreased frequencies of HLA-B27, B40, DR13, and DQ1*0604 (P < 0.05) and an increased frequency of HLA-B35 (P < 0.05) were found in groups 1 and 2 compared with controls (group 3). None of the differences detected in the phenotype frequencies of HLA alleles were statistically significant after correction. CONCLUSIONS We conclude that the susceptibility to HBV infection and the different courses of HBV infection are not strongly related to HLA status in Caucasians.

Abstract
An allogeneic transplantation programme using immunoselected blood progenitor and bone marrow CD34+ cells has been established. Thirteen healthy HLA-matched, MLC negative sibling donors received two doses of 5 micrograms kg-1 G-CSF (s.c. daily) for 5 days. On days 4 and 5, large-volume mononuclear cell aphereses were performed (COBE Spectra) and on day 5 one unit of autologous blood was obtained. Mononuclear cells were pooled and cryopreserved after CD34+ cell-immunoselection on day 5. Bone marrow (BM) of the same donors was procured under routine conditions 10-45 days later (median: 27 days). The final graft consisted of blood CD34+ cells with either complete BM (n = 5) or immunoselected BM CD34+ cells (n = 8). The present paper describes the progenitor cell mobilization and apheresis protocol and analyzes the cell loss by BM and peripheral blood progenitor cell (PBPC) donation. Considerably larger amounts of mononuclear cells (CD45+), T-lymphocytes (CD3+) and platelets were lost by the apheresis as compared to bone marrow without apparent immediate clinical consequences for the donors. Owing to cross-cellular contamination of the apheresis concentrate, blood platelet count (PC) significantly decreased (mean PC after the second apheresis 116 x 10 microL-1); furthermore on average 3.04 x 10(10) CD3+ cells were removed by two apheresis sessions. This loss did not lead to long-term total lymphocyte count changes (2370 microL-1 versus 1889 microL-1) as observed during the long-term follow-up of 7/13 donors (mean 290 days). Subjectively, the PBPC collections were better accepted than BM donations in all but one family donor.

Abstract
In hepatitis C, both susceptibility to infection and the course of disease may depend on differences in the immune response. As the major histocompatibility complex (MHC) plays a crucial role in antigen presentation, we investigated a possible relationship between susceptibility to hepatitis C virus (HCV) infection and human leucocyte antigen (HLA) alleles. Therefore, phenotype frequencies of HLA were compared in 186 anti-HCV positive patients with end-stage renal disease (ESRD) to 328 anti-HCV negative patients with ESRD. HLA class I alleles were determined serologically and HLA class II alleles (DRB1, DQA1, DQB1) by the polymerase chain reaction sequence-specific oligonucleotide (PCR-SSO) technique. Additionally, in anti-HCV positive patients we looked for a relationship between the activity of hepatitis C (indicated by elevation of transaminases or the presence of viremia) and HLA determinants. For the three criteria (antibody status, elevation of transaminases and viremia) a significant association to HLA alleles was not found in patients with ESRD. This suggests that neither susceptibility to HCV infection nor the biochemical activity of hepatitis and HCV-RNA positivity seem to be strongly related to HLA status in Caucasian patients with end-stage renal disease.

Abstract
PATIENTS AND METHODS From January 1986 until August 1995 230 adult patients received an allogeneic or autologous transplantation of bone marrow or hematopoietic blood stem cells. The conditioning and myeloablative treatment regimens were chosen according to the underlying disease and type of transplant. RESULTS The observation period comprises 1 to 115 months after transplantation. After allogeneic transplantation from HLA-identical family donors, the probabilities of disease-free survival were for acute myeloid leukemia in first complete remission (CR) (n = 35) 77%, for acute lymphoid leukemia in 1st CR (n = 7) 72% and in 2nd CR (n = 10) 40%, in first chronic phase of chronic myeloid leukemia (n = 34) 50% and in severe aplastic anemia (n = 7) 100%. Following myeloablative therapy and autologous transplantation the probabilities of disease-free survival were 47% in relapsed Hodgkin's disease (n = 22) and 42% for relapsed high-grade non-Hodgkin's lymphoma (n = 12). Eight of 10 patients with acute myeloid and 7 of 8 with acute lymphoid leukemia suffered a leukemic relapse after autologous bone marrow transplantation. Three of 8 patients with relapsed testicular cancer survived relapse-free. Treatment failures were due to more advanced acute graft versus host disease after allogeneic transplantation and caused by relapse after autologous transplantation. Current protocols evaluate the allogeneic transplantation of enriched CD34+ blood stem cells. In chronic myeloid leukemia the autologous transplantation of blood stem cells after myeloablative therapy is being studied.

Abstract
To simplify DQA and DQB oligotyping, we applied our improved PCR-SSO procedure for DR typing. We used 12 oligonucleotide probes for DQA typing and 18 for DQB typing. Oligonucleotide probes that require the same hybridization and stringent washing conditions were selected as pairs for simultaneous hybridization to a dot-blot membrane containing various DNA samples. One probe of each pair was labeled with digoxigenin and the other with biotin. After hybridization, the dot-blot membranes were incubated with a mixture of conjugates. Specific binding of the corresponding DNA probes was visualized on an X-ray film using a chemiluminescent substrate (CSPD) and by staining using a chromogenic substrate (TMB). This approach, previously employed for DR typing, is also suitable for DQA and DQB oligotyping and significantly reduces the labor inherent in PCR-SSO typing.

Abstract
BACKGROUND Cryopreservation is the only available method for the long-time maintenance of blood cells. The present study was designed to prove: (i) the reliability of multiparameter flow cytometry (MFC) for estimation of CD34+ cells in frozen-thawed cell suspensions and (ii) the acceptability of a new teflon container for the cryopreservation of hematopoietic progenitor cells. MATERIALS AND METHODS Each of 15 ABO-compatible buffy coats (BC) were pooled, and mononuclear cells (MNC) were then separated with the Fresenius AS 104 device (n = 10). MNC harvested by apheresis were then divided into 2 portions and transferred pairwise into either the new Fresenius or into Gambro cryopreservation containers. Paired samples were frozen at controlled rates (9% DMSO final concentration) and stored at -196 degrees C in liquid nitrogen for 2 weeks. Leukocyte, MNC and differential blood counts and proportions of CD3+, CD4+, CD8+, CD14+ and CD34+ cells were assessed from the pooled BC, the apheresis products, and the frozen-thawed samples. Methyl cellulose culture assays as well as trypan blue viability staining were also carried out. RESULTS The mean content of the divided apheresis products was 4.9 x 10(9) leukocytes with 86% MNC, 6.89 x 10(6) CD34+ cells, 2.1 x 10(5) granulocyte-macrophage colony-forming units (CFU-GM) and 7.1 x 10(5) erythroid burst-forming units (BFU-E). As expected, there were virtually no granulocytes after freezing in both types of container. The corresponding mean cell content was as follows: 6.3 x 10(6) CD34+ cells, 2.5 x 10(5) CFU-GM, and 8.1 x 10(5) BFU-E in Fresenius containers, and 6.1 x 10(6) CD34+ cells, 1.3 x 10(5) CFU-GM, and 7.7 x 10(5) BFU-E in Gambro containers. The mean MNC viability of the samples frozen in Fresenius was 81.5% and 82.7% in the Gambro containers. MFC was found to compare with stained smear differentials. CD34+ cell counts correlated with CFU-GM (0.69, p = 0.03) and BFU-E (0.63, p = 0.02) colony formation. CONCLUSIONS The study reported here revealed no significant differences between the 2 types of storage containers. The new Fresenius teflon container could thus be recommended for cryopreservation of hematopoietic progenitor cells. MFC provided reliable data on CD34+ cell content and leukocyte subset composition of the frozen-thawed cell suspension.

Abstract
OBJECTIVE Two different types of polyolefin storage containers were compared in order to estimate their ability to preserve apheresis platelet concentrates for 5 days. MATERIAL AND METHODS Ten pairs each consisting of one patient with thrombocytopenia following chemotherapy and one healthy platelet apheresis donor were examined. The platelet concentrates stored in the LE-2 bag were collected with a Fresenius AS 104 cell separator and those stored in the PL 732 with a Fenwal CS 3000. RESULTS The separation efficiency of both cell separators was similar; the mean yields were 3.37 +/- 0.83 x 10(11) platelets in 274 +/- 26 ml for the AS 104 and 3.87 +/- 1.31 x 10(11) platelets in 318 +/- 22 ml for the CS 3000 (mean +/- SD). Storage for 5 days did not influence the platelet count significantly. The platelet loss due to filtration was 16 and 13%, respectively. The mean platelet volume obtained with both systems was reduced from a mean of 8.4 fl immediately after harvesting to 7.6 fl after storage (p < 0.0001) and to 7.3 fl after filtration (p = 0.001). The established corrected count increments (CCI) and the pre- and posttransfusion platelet counts were satisfactory and comparable for the 2 systems tested. The mean CCI of the AS 104-LE-2 system was 14.5 1 h and 7.4 x 10(9) platelets 24 h after transfusion, the mean CCI of the CS 3000-PL 732 system was 12.5 and 5.2 x 10(9) platelets, respectively. CONCLUSIONS Single-donor apheresis concentrates with a large platelet content may be stored in the new LE-2 polyolefin container for up to 5 days and used in clinical transfusion.

Abstract
To simplify PCR-SSO HLA-DRB generic typing, we labeled eight of 15 oligonucleotide probes with DIG and the others with biotin, and hybridized each dot blot with both a biotin-labeled probe and a DIG-labeled probe simultaneously. We chose oligonucleotide pairs which require the same hybridization and stringent washing conditions and do not compete with each other during hybridization. After incubation with a mixture of anti-DIG Fab fragment-alkaline phosphatase and streptavidin-peroxidase conjugates, specific binding of the DIG-labeled probe was revealed by a chemiluminescent substrate (CSPD) and specific binding of the biotin-labeled probe was subsequently visualized by a chromogenic substrate (TMB). The sensitivity of both probes was similar and gave comparable hybridization signals. Using this simplified procedure, the number of hybridizations or dot blots can be reduced to half the usual amount and the labor involved in PCR-SSO typing significantly reduced.

Abstract
There is a proven relation between cytomegalovirus (CMV) infection in seronegative immunocompromised patients and transfusion of random CMV unscreened cellular blood products (BP), where the leukocytes are thought to be the vector of transmission. We examined whether freezing, thawing, and washing, in attempt to reduce the quantity of leukocytes, also reduces the CMV-DNA-carrying cells of BP of CMV-seropositive donors and their infectivity for fibroblasts, using the polymerase chain reaction (PCR). The leukocyte contamination of the thawed-washed erythrocyte concentrates was < 1 x 10(8)/l and of the thawed-washed platelet concentrates, approximately 2.5 x 10(8)/l. All plasma samples and most samples of BPs of the CMV-seronegative controls were PCR-CMV-DNA-negative. The differences of the PCR results with the samples of CMV-seropositive donors before and after freezing were not significant. Thus we concluded that freezing-thawing-washing of cellular BP could not eliminate all CMV-DNA-bearing leukocytes. Plasma carries low risk for CMV infection, if at all.

Abstract
The measurement of reactive oxygen species provides a simple method for monitoring the degree of activation of leukocytes in various disorders, and for determining the effects of drugs on this activation. The present report describes the determination of luminol- or lucigenin-amplified chemiluminescence of whole blood in a microtitre plate assay with a 96-well luminometer (HAMAMATSU MTP reader). Using heparinized venous human blood from healthy donors, optimal chemiluminescence intensities were determined at a blood dilution of 1/100 in a total volume of 0.25 ml of Hank's balanced salt solution, containing 0.4 mmol/l luminol as enhancer and either opsonized zymosan (1 milligram) or the phorbol ester, 12-O-tetradecanoylphorbol 13-acetate (10(-6) mol/l), as stimuli. The in vitro effects of nordihydroguaiaretic acid, diphenylene iodonium, and diclofenac were tested. After preincubation of the diluted whole blood with these drugs for 15 min, the zymosan-stimulated chemiluminescence was diminished in all cases. The specific NADPH oxidase inhibitor, diphenylene iodonium, was most effective (half maximal inhibition at 1.5 x 10(-8) mol/l), whereas higher concentrations of the antioxidant, nordihydroguaiaretic acid (1.6 x 10(-6) mol/l), or the nonsteroidal antiinflammatory drug, diclofenac (about 10(-5) mol/l), were needed to achieve half maximal inhibition. In addition to its usefulness in the rapid screening of drug effects this assay system seems to be very beneficial for the clinical diagnosis of congenital disorders. Furthermore, it is suited as an effective and simple method for the continuous determination of the phagocyte functional state in patients in pathophysiological situations and during therapy.

Abstract
Immunoglobulin heavy chain (G1m, G2m, G3m, A2m) and kappa light chain (Km) allotype and phenotype frequencies of 323 central European Caucasian patients with systemic lupus erythematosus (SLE) were examined and correlated with various genetic, serologic and clinical markers of SLE. No significant associations were found between immunoglobulin allotypes or phenotypes and all 20 parameters tested (nephritis, vasculitis, arthralgias, photosensitivity, discoid lesions, central nervous system disease, Raynaud's phenomenon, sex, anti-Ro, anti-La, anti-nRNP, HLA-DR1-DR7, HLA phenotypes B8-DR3, B7-DR2). It could therefore be assumed that Gm, A2m and Km allotypes were not associated with HLA-antigens and had no influence on the serologic and clinical expression of SLE.

Abstract
An analysis of HLA class II antigens in 356 white patients with systemic lupus erythematosus (SLE) showed that all HLA-DR and -DQ homozygous and heterozygous combinations appear with frequencies expected from the observed gene frequencies. HLA-DR2 and HLA-DR3 gene frequencies were both increased in SLE, as were the odds ratios of all DR2 and DR3 hetero- and homozygous combinations. HLA-DR2/C4AQ0 heterozygotes were also not increased over expected values. Therefore, gene complementation at MHC loci does not contribute to susceptibility to SLE, but rather one or two MHC allele(s) in linkage with HLA-DR2 and HLA-DR3.

Abstract
Liver transplantation in HBs-antigen (HBsAg) positive allograft recipients is associated with a high risk of HBV recurrence some time after surgery. So far, results of measures to prevent recurrent HBV-infection by means of treatment with interferon, hepatitis B vaccination and short-term passive immunization with hepatitis B immunoglobulin (HBIg) or monoclonal antibody to HBsAg (anti-HBs) have been disappointing. In the present study the results of long-term, anti-HBs monitored passive immunization with HBIg is reported. In 23 HBsAg-positive liver transplant recipients an anti-HBs level of greater than or equal to 100 IU/l was maintained for 6 or 12 months, respectively. The rate of recurrent infection was found to be less than 20% under HBIg substitution, whereas 11 graft recipients with no or only short-term HBIg prophylaxis were reinfected by month 15 after transplantation. HBV recurrence was associated with chronic liver disease and recurrent cirrhosis in the allograft.

Abstract
Multidrug resistance refers to a complex cellular phenotype, the hallmark of which is cross-resistance to multiple drugs, for example, chemotherapeutic agents, that are unrelated to the selecting agent in structure, cellular target, and mode of action. The expression of this multidrug resistance is connected with the overexpression of P-glycoprotein. By applying the method of immunocytochemical assay, we have demonstrated the appearance of the multidrug-resistant phenotype (P-glycoprotein+ cells, multidrug-resistant cells) in mononuclear cells of the peripheral blood from 32/49 patients receiving triple-drug (azathioprine, steroids, cyclosporine) immunosuppressive therapy after heart transplantation. In the group of patients showing not only the presence of cells with multidrug-resistant phenotype in the peripheral blood, but also a significant increase in the number of these cells during the interval of observation (0 to 767 days)-16/32/49 cases--a significantly increased incidence of acute rejection episodes could be demonstrated. This supports the hypothesis of a possible existence of a therapy-resistant form of acute rejection, with an involvement of mechanisms of multidrug-resistance playing a role in its causal development.

Abstract
501 blood donors from Bremen have been typed for HLA-ABC and -DR. The results are compared with HLA data obtained on 474 blood donors from Hannover. The gene frequencies do not differ significantly between these two population samples. Comparisons with population samples from Kiel, Hamburg, Essen, Frankfurt/M., Mainz, Mannheim, Freiburg/Br., Munich and Vienna did also not reveal any remarkable differences concerning the gene frequencies. Analysis of linkage disequilibrium of two-factor and three-factor haplotypes could show that the typical Caucasoid allele combination A1/B8 is not a constituent part of three-factor haplotype combinations. Between the population samples from Bremen and Hannover no marked differences in the distribution of two-factor and three-factor haplotype frequencies could be found.

Abstract
A set of early diagnostic (ED) criteria comprising clinical data, ESR, radiological spinal signs, and the risk factor HLA B27 was evaluated after 5 and 10 years in a follow-up of 54 patients with an initial diagnosis of possible ankylosing spondylitis (AS). After 10 years 32 patients (59%) had developed definite AS according to the New York criteria, 10 individuals (19%) had possible or undifferentiated spondylarthropathy (SA), whereas in 12 patients (22%) other diagnoses were stated. ED criteria had a high discriminatory significance for the development of AS after 5 and 10 years (P less than 0.005, P less than 0.001 respectively). In this respect they were more valuable than B27 determination alone (P less than 0.01) or the ED criteria without HLA B27 (P less than 0.05). Furthermore, patients with still possible or undifferentiated SA had a higher mean score at the first examination than individuals with other final diagnosis (P less than 0.05). Thus, the ED criteria were useful for the identification of patients developing definite AS and of individuals in the AS related group of possible or undifferentiated SA.

Abstract
The irradiation of blood components is supposed to be the safest way of the graft versus host reaction prophylaxis. The radiotherapy facilities and compact irradiators for blood preparations and biological materials are used for prophylactic irradiations, practically. The radiotherapy machines allow a homogeneous dose application, but need a high organizing effort. The use of compact irradiators is less complicated but the large dose differences can be found in the target volume. There is no agreement about the extent of the prophylactic dose. For radiation biology reasons the application of prophylactic doses between 15 and 50 Gy seems to be justified. A restriction of this range in favor of higher doses can be expected, when newer experimental findings are proven by clinical observations.

Abstract
Eighty-eight patients with possible ankylosing spondylitis (AS) were selected for this followup study. They showed normal or at most suspicious radiographic findings of the sacroiliac joints. After 5 years' followup, 24, and after 10 years 32 patients (59% of the 54 finally available, 36% of the 88 original patients) had definite AS. In 12 individuals, AS could be excluded. Of the 10 remaining patients, 6 still had possible, and 4 had undifferentiated spondyloarthropathy. A comparison between HLA-B27 positive and negative patients showed a significantly increased frequency of definite AS or possible and undifferentiated spondyloarthropathy (p less than 0.05) in the group of HLA-B27 positive patients. The development of AS was characterized by a prolonged course: radiological sacroiliitis became evident after at least 9 +/- 6 years, radiological signs of spinal involvement after 11 +/- 6 years mean disease duration. After 18 +/- 6 years 25 (78%) of 32 patients with AS still maintained good or sufficient functional capacity, indicating a good functional prognosis in the great majority of the patients.

Abstract
It has been shown that fatal "poisoning" with the mushroom species Paxillus involutus is caused by antibodies against the fungus in sensitized patients. Because circulating immune complexes play an important role, therapeutic procedures which can eliminate those complexes could stop immune hemolysis. A 37-year-old patient became severely ill after repeated ingestion of sufficiently cooked Paxillus involutus. As a result of hemolysis with reversible shock symptoms, acute renal failure developed. Plasma exchange with 3,000 ml albumin 5% was carried out daily during the first 3 days after admission. Each plasma exchange lowered free hemoglobin and immune complex levels by 60%-75%. Acute renal failure was successfully treated with hemodialysis. Specific IgG-antibodies against membrane particles of Paxillus involutus were detected by hemagglutination tests in the serum of the patient. The sequence of reactions resulting from the testing procedures strongly suggests the formation of immune complexes. These complexes are likely to bind to erythrocytes acting as innocent bystanders. Activation of the complement system finally results in hemolysis and shock. In addition to adequate shock treatment elimination of these immune complexes by plasma separation seems to be the therapy of choice.

Abstract
A family study was performed in 24 members of a Turkish sibship with familial Mediterranean fever (FMF) with 5 patients affected in 3 generations. The well-known autosomal-recessive inheritance of the disease was masked by a pseudodominant appearance, reflecting the striking frequency of congenial marriages. The immunogenetic investigation excluded a linkage between the expression of the disease and the HLA system. The arthritis of FMF was characterized typically by monarticular attacks in large joints of the lower limb. Frequently this manifestation led to diagnostic problems, particularly at the onset of the disease. No patient presented the clinical or radiological signs of sacroileitis. An observation of the disease process up to 3 years showed a benign prognosis of FMF-arthritis in 3 of 4 patients. Neither long-lasting functional impairment nor radiological signs of erosion had to be recognized. One patient suffered from a necrosis of the femoral head, possibly caused by the recurrent inflammation of the hip joint. Laboratory findings reflected the clinical picture of relapsing acute inflammation in an uncharacteristic manner. Their diagnostic significance exists mainly for the exclusion of other diseases.

Abstract
A conventional in vitro test assay was used to determine maximal bactericidal capabilities of human granulocytes. By means of a mathematical model the maximal phagocytosis and killing activity could be calculated for S. aureus and P. aeruginosa serving as test organisms. The evaluation allowed moreover the determination of the optimal bacterial load and also of critical bacterial concentrations leading to a complete depression of observable granulocyte killing functions. In contrast to other studies frozen suspensions of bacteria were used allowing the employment of identical microorganisms within a complete series of experiments. On average one granulocyte was found to ingest a maximum of 17 CFU of S. aureus with 9 CFU killed under optimal ratios of bacteria per granulocyte. For P. aeruginosa the granulocyte function reached peak values of 96 CFU ingested and 62 CFU killed per one granulocyte. The new assay might provide a highly reproducible method for clinical assessment of granulocyte dysfunctions in various diseases.
