Abstract
We assessed whether complement and its factor C4 or abnormal immunoglobulin levels are associated with chronic or recurrent rhinosinusitis. We used multiple patient and control groups to obtain clinically meaningful data. Adult chronic or recurrent rhinosinusitis and acute purulent rhinosinusitis patients were compared with unselected adults and controls without previous rhinosinusitis. Associated clinical factors were reviewed. Levels of immunoglobulins, plasma C3, C4 and classical pathway haemolytic activity were analysed. C4 immunophenotyping was used to detect C4A and C4B deficiencies as null alleles. Complement was up-regulated in rhinosinusitis. C4A nulls and low IgA, IgG, IgG1, IgG2, IgG3 and IgG4 levels were all more common in chronic or recurrent rhinosinusitis patients than in unselected and healthy controls. We searched for relevant differences between the patient groups. According to stepwise logistic regression analysis, nasal polyposis [odds ratio (OR) 10.64, 95% confidence interval (CI) 2.5-45.7, P = 0.001], bronchial asthma (OR 8.87, 95% CI 2.3-34.9, P = 0.002), C4A null alleles (OR 5.84, 95% CI 1.4-24.9, P = 0.017) and low levels of IgG4 together with either IgG1 or IgG2 (OR 15.25, 95% CI 1.4-166.8, P = 0.026) were more common in chronic or recurrent rhinosinusitis than in acute rhinosinusitis patients. Isolated low IgG subclasses had limited value in patient assessment. C4A null alleles are associated with chronic or recurrent rhinosinusitis, potentially through their effect on immune defence and inflammation control. Multiple clinical and immunological parameters may need to be evaluated when searching for prognostic variables.

Abstract
The tumor necrosis factor alpha (TNF-alpha) -308 G/A and TNF-beta NcO1 polymorphisms have been described to be associated with an increased risk for sepsis in critically ill patients. Functional consequences associated with these polymorphisms remain unclear. We compared the genotype distribution of these TNF polymorphisms with susceptibility to severe sepsis and leukocyte function in blunt trauma patients (n = 70; mean injury severity score, 24 points [range, 4 to 57). Severe sepsis was defined according to the American College of Chest Physicians-Society of Critical Care Medicine consensus conference criteria. Genotyping for the NcO1 polymorphism (alleles TNFB1 and TNFB2) was performed by PCR and digestion of the products with NcO1, and that for the TNF-alpha -308 G/A polymorphism (alleles TNF1 and TNF2) was performed by real-time PCR. Leukocyte function was assessed by measurement of the production of endotoxin-induced cytokines (TNF-alpha, interleukin-6 [IL-6], and IL-8) in whole blood. TNF-alpha, IL-6, and IL-8 were determined by enzyme-linked immunosorbent assay. For the genotypes of the TNF-alpha -308 G/A polymorphism, differences in the frequency of development of severe sepsis were not detectable. Patients developing severe sepsis after trauma were significantly more likely to possess a homozygous genotype of the TNF-beta NcO1 polymorphism. Compared with heterozygotes, the odds ratio for the TNFB2/B2 genotype for the development of severe posttraumatic sepsis was 11 (P = 0.01), and that for the TNFB1/B1 genotype was 13 (P = 0.014). TNF-alpha -308:TNF-beta NcO1 haplotype analysis showed that the TNFB2:TNF2 haplotype is significantly negatively associated with development of severe sepsis. Patients homozygous for the TNFB1 or TNFB2 allele showed a persistently higher cytokine-producing capacity during at least 4 to 8 days after trauma than the heterozygotes. In patients homozygous for the TNF1 allele, a higher TNF-alpha- and IL-8-producing capacity was found only at day 1 after trauma. Although the TNF-beta NcO1 polymorphism appears to be less likely to be causative for development of severe sepsis after trauma, it is thus far the only genetic marker identified which can be used as a relevant risk estimate for severe sepsis in trauma patients immediately after the injury.

Abstract
OBJECTIVE To investigate the relation of the biallelic Nco1 restriction fragment length polymorphism in the first intron of the tumor necrosis factor (TNF) beta gene with the development of severe sepsis in multiply injured patients. SUMMARY BACKGROUND DATA The biallelic Nco1 polymorphism of the TNFbeta gene has been described to be associated with autoimmune diseases and with the mortality rate in severe sepsis. Therefore, the Nco1 polymorphism may be associated with the clinical finding that despite comparable risk factors, posttraumatic sepsis develops in some patients but not others. METHODS The study group consisted of 110 patients with severe blunt trauma (Injury Severity Score > or = 17). Typing of each patient for the biallelic Nco1 polymorphism was performed by analyzing restriction fragments of an Nco1-digested DNA fragment obtained using polymerase chain reaction. Genotypes were then related to the occurrence of severe posttraumatic sepsis and TNFalpha serum concentrations. RESULTS Fifty-seven patients showed an uncomplicated posttraumatic recovery, and severe sepsis developed in 53 patients. The overall allele frequency (TNFB1 0.29, TNFB2 0.71) and genotype distribution (TNFB1 homozygous 7.3%, TNFB1/TNFB2 42.7%, TNFB2 homozygous 50%) were in agreement with the distribution in healthy volunteers. Genotype distribution in patients with an uncomplicated clinical course was significantly different from that in patients with severe posttraumatic sepsis. Development of severe posttraumatic sepsis was significantly increased in patients homozygous for the allele TNFB2. In patients with severe posttraumatic sepsis, TNFalpha serum concentrations were significantly higher in TNFB2-homozygous individuals compared with heterozygous and TNFB1 -homozygous individuals. The age- and injury-matched odds ratio for the homozygous TNFB2 genotype compared with the heterozygous genotype was 5.22 (p = 0.007, 95% confidence interval 1.6 to 17.9). CONCLUSIONS In multiply injured patients, the Nco1 polymorphism within the TNFbeta gene is associated with the development of severe posttraumatic sepsis and with increased TNFalpha serum levels when severe sepsis has occurred. This suggests a genetic determination of the individual inflammatory response after infection or tissue damage, which significantly influences susceptibility to severe nosocomial infections.

Abstract
OBJECTIVE Recent studies have demonstrated an association between a microsatellite polymorphism of the CTLA-4 gene, specifically a 106 base pair allele, and both Graves' disease and autoimmune hypothyroidism. The aim of the present study was to determine whether the same polymorphism of the CTLA-4 gene was associated with autoimmune Addison's disease. DESIGN AND PATIENTS We analysed a microsatellite polymorphism (variant lengths of a dinucleotide (AT)n repeat) within exon 3 of the CTLA-4 gene in the following groups: 21 English patients with non-associated Addison's disease, 18 with autoimmune polyglandular syndrome type 2 (APS2) and 173 healthy control subjects; 26 Norwegian patients with non-associated Addison's disease, 9 with autoimmune polyglandular syndrome type 1 (APS1), 17 with APS2 and 100 controls; 3 Finnish patients with non-associated Addison's disease, 5 with APS2 and 71 controls; 10 Estonian patients with non-associated Addison's disease, 2 with APS2 and 45 controls. MEASUREMENTS The CTLA-4 microsatellite gene polymorphisms were determined by polymerase chain reaction amplification of genomic DNA and resolution of the products on sequencing gels. RESULTS The frequency of the 106 base pair allele was significantly increased in the groups of English patients with either non-associated Addison's disease or APS2 (P = 0.02 and 0.04, respectively), when compared to healthy controls with no clinical evidence or family history of either Addison's disease or any other autoimmune disorder. For Norwegian patients with either non-associated Addison's disease, APS1 or APS2, there was no association (P = 0.69, 0.62 and 0.97, respectively). This was also the case for Finnish patients with either non-associated Addison's disease or APS2 (P = 0.23 and 0.28, respectively) and for Estonian patients with either non-associated Addison's disease or APS2 (P = 0.34 and 0.29, respectively). CONCLUSIONS These results indicate that differences exist in the frequency of the 106 base pair allele in different population groups and in only the English population was the 106 base pair allele associated with Addison's disease.

Abstract
The tumor necrosis factor B (TNFB) gene is closely liked with tumor necrosis factor A (TNFA) gene between the HLA-B and C2 genes on chromosome 6p21.3. Several genetic variabilities at the human TNFB loci have been identified, which are the NcoI restriction fragment length polymorphism (RFLP) in the first intron, amino acid substitution at codon 26 of exon 3 and EcoRI RFLP in untranslated exon 4. The NcoI RFLP of TNFB gene gives two allelic fragments of 238/259 bp and 497 bp, corresponding to TNFB*1 and TNFB*2 alleles, respectively. To investigate the frequency of NcoI RFLP in the first intron of TNFB in Koreans and to compare to that of other ethnic population, genomic DNAs were extracted from leukocytes of 305 unrelated healthy Koreans and amplified the first intron of TNFB gene by PCR. The phenotype frequencies of NcoI RFLP such as TNFB* 1/TNFB*1, TNFB*1/TNFB*2 and TNFB*2/TNFB*2 were 8.6% (n = 26), 45.2% (n = 138) and 46.2% (n = 141), respectively. The estimated allele frequencies for TNFB*1 and TNFB*2 were 0.3115 and 0.6885, respectively. The observed and expected frequencies were in good agreement with the Hardy-Weinberg's equilibrium. The heterozygosity revealed 45.2% and the allele frequencies of NcoI RFLP of TNFB in Koreans were observed comparatively similar to those of other ethnic groups.

Abstract
The major autoantigens in Addison's disease have recently been shown to be members of the adrenal steroidogenic enzymes, such as 21OH. The genes encoding the 21OH enzyme are located in the class III segment of the MHC complex. Therefore, its identification as an autoantigen provides a novel link between MHC and susceptibility to this autoimmune disease. We have determined the MHC class II (DRB1, DQA1, DQB1, DPB1) and class III (TNF, HSP70, C4, 21OH) gene polymorphism in patients with Addison's disease. Also, we tested whether presence of autoantibodies against 21OH is associated with specific alleles in MHC. Our results show that patients with Addison's disease in association with APS2 or Addison's disease as an isolated form share highly similar MHC class II and class III alleles. A very strong association with HLA DRB1*0301, DQA1*0501, DQB1*0201, and DPB1*0101, as well as with the C4A + 21OHA gene deletion and TNFB*1 allele was observed. However, identical gene markers were observed also in controls matched for DRB1*0301, thus suggesting that the patient group did not carry MHC gene segments specific for Addison's disease. The presence of autoantibodies against 21OH was not found to be directly determined by the MHC alleles; rather it was associated with the clinical form of the disease.

Abstract
HLA-DR and -DQ typings were performed by a combination of RFLP and PCR-SSP techniques in 234 Danish women with at least three consecutive unexplained fetal losses (recurrent fetal losses) and 360 controls and the DRB1, DQA1 and DQB1 alleles were deduced. In the total group of patients, the frequency of no DRB1-DQA1-DQB1 haplotype was significantly increased compared with controls. In the subgroup of 97 women with four or more fetal losses (multiple fetal loss group), the frequency of women carrying the DRB1*0101, DQA1*0101, DQB1*0501; DRB1*0102, DQA1*0101, DQB1*0501 and DRB1*0103, DQA1*0101, DQB1*0501 haplotypes or the DRB1*0301, DQA1*0501, DQB1*0201 haplotype were significantly increased compared with controls (RR = 2.1; pc < 0.05 with regard to former three haplotypes combined and RR = 2.2; pc < 0.05 for the latter). The frequency of women with at least one of the four haplotypes was significantly (p < 0.002) increased with the number of previous fetal losses in the women's history. Analysis of the DQA1 and DQB1 phenotypes in women with at least four fetal losses showed that DQA1*0501 and DQB1*0501 were increased compared with controls (RR = 1.9; pc < 0.05 and RR = 2.2; pc < 0.025, respectively). Analysis of DRB1-DQA1-DQB1/DRB1-DQA1-DQB1 genotypes suggested that genotypes comprising both DQA1*0501 and DQB1*0501 alleles (in trans) exhibited a higher RR for experiencing at least four fetal losses (RR = 3.4, p = 0.002) than each of the alleles did alone.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The polymorphism of Major Histocompatibility Complex (MHC) class II genes DRB, DQA, DQB, and DPA was studied by TaqI Restriction Fragment Length Polymorphism (RFLP) in recurrent spontaneous abortions (RSA). The study group consisted of 35 primary abortion (PA) couples (no children) and 15 secondary abortion (SA) couples (1-2 children before abortions). We found no increase in DR-DQ compatibility between the mother and the foetus in the Finnish RSA group. In contrast to findings in some other populations, foeto-maternal incompatibility was increased in the PA group. Thus, our results do not support the theory that increased MHC class II compatibility is a cause of abortions as such. The Finns are a small and relatively isolated population with a unique gene inheritance. Thus, one can speculate that, if the human MHC class II is in the linkage with disadvantageous 'fertility genes', and these genes might nonetheless still be clustered in only a few MHC haplotypes among the Finns. This would be the reason, that DR-DQ sharing is not seen. The presence of rare HLA alleles, such as DR2 and DR6, among the aborters also supports this. In addition, this study extends our previous findings on MHC class III in regards to PA and SA couples differing immunogenetically from each other. In MHC class II, this was most obvious in the DPA1 locus. The vast majority of SA women were heterozygous for the two most common DPA1 alleles (14.0 kb and 13.5 kb), resulting in significantly smaller chances for a DPA1 mismatched foetus to occur in the SA group than in the controls or in the PA women.

Abstract
PROBLEM AND METHOD The role of major histocompatibility complex (MHC) genes in the etiology of recurrent spontaneous abortion (RSA) was studied by analyzing the polymorphism of several, at least 14, immunogenetically important MHC genes either by serological or molecular methods in 56 Finnish RSA couples, and in 29 infants born to these families during the follow-up period of two years after the abortions. RESULTS The haplotype analysis showed that the RSA couples had significantly increased sharing of MHC fragments, compared to the control families. Furthermore, the MHC risk markers for abortions defined 12 different, extended MHC haplotypes that were found in a significantly higher proportion among persons in the RSA group (45%) than in the controls (11%). However, neither of these observations associated with the reproductive success of the study couples. CONCLUSIONS The results suggest that extended MHC haplotypes, disadvantageous for reproduction, exist in some isolated populations, such as the Finns.
