This paper lists the genotype frequencies of 50 polymorphisms of 37 genes (ALDH2, ADRB2, ADRB3, COMT, CD36, CXCR2, CCND1, COX2, CYP2A6, CYP17, CYP19, IGF1, IL-1A, IL-1B, IL-1RN, IL-1R1, IL-6, IL-8, IL-10, LEP, Le, L-myc, MPO, MTR, MTHFR, MAO-A, NQO1, OGG1, p53, p73, Se, SRD5A2, TGF-B, TNF-A, TNF-B, XPD, and XRCC1) and 6 sets of combined genotype frequencies for 241 non-cancer Japanese outpatients. Though the genotype frequencies of 25 polymorphisms have already been reported in our previous papers, 15 polymorphisms (CD36 A52C, CXCR2 C785T, CCND1 G870A, IGF1 C/T at intron 2 and G2502T, IL-1A 46-bp VNTR, IL-1R1 C-116T, IL-6 Ins/Del 17C, IL-8 A-278T and C74T, IL- 10 T-819C, LEP A-2548G, SRD5A2 2-bp VNTR, XPD Lys751Gln, and XRCC1 Arg399Gln) and six sets of combined genotype frequencies (IL-1B C-31T and IL-1A C-889T, IL-1B C-31T and IL-1RN 86-bp VNTR, IL-1B C-31T and IL-1R1 C-116T, TNF-A G-308A and TNF-B A252G, SRD5A2 Val89Leu and 2-bp VNTR, and XRCC1 Arg399Gln and XPD Lys751Gln) were reported in this paper for the first time for Japanese. Although microarray technology will produce this kind of information in near future, this is the first document that reports the genotype/allele frequencies among Japanese for an archival purpose.

We investigated the effects of instrumentation on postoperative inflammatory reaction and identified standard changes in serum cytokine concentrations after spinal surgery. Pro-inflammatory cytokines [interleukin (IL)-6 and IL-8] and anti-inflammatory cytokines [IL-10, IL-1 receptor antagonist (ra), and soluble tumor necrosis factor receptors (sTNF-R) I and II] were assayed in serum from seven patients with lumbar spinal posterior decompression, six with spinal decompression and posterolateral fusion without instrumentation and seven with spinal decompression and posterolateral fusion with instrumentation. All cytokines after spinal instrumentation increased significantly more than in other groups on postoperative days 0 and 1. Seven days after SI, IL-6, -8, and -10 had normalized, but IL-1ra and sTNF-RI and sTNF-RII remained elevated. Both pro-inflammatory and anti-inflammatory cytokines were enhanced by implants in the acute phase, whereas only anti-inflammatory cytokines were enhanced by instruments in the subacute phase.

The clinical implications of increased cytokine levels after major surgery remain unclear. In this study, systemic concentration of a spectrum of cytokines, including interleukins IL-6, IL-8, IL-10, IL-1ra, and soluble tumor necrosis factor receptor-I (sTNF-RI) was examined in patients with and without postoperative septic complications following colorectal surgery. Although there were no significant changes in IL-1beta, TNF-alpha, and IL-8 serum levels during the observation period, there was a significant rise in IL-6, IL-1ra, and sTNF-RI concentrations in the entire group of patients between postoperative day 1 and 14. There were no differences between the group without and with local complications when IL-6, IL-1ra, and IL-10 were examined. The serum levels of sTNF-RI, IL-1ra, and IL-6 were found to be sensitive indicators of the pro- and anti-inflammatory response to the surgical trauma, but only sTNF-RI turned out to be a sensitive early marker of local septic postoperative complications in patients with colorectal carcinoma.

Inflammation plays a critical role in lung disease progression in cystic fibrosis (CF). This inflammatory process is dominated by a neutrophil influx in the airways. To determine whether the accumulation of neutrophils in the airways of CF patients is associated with an altered function, we analyzed the capacity of neutrophils isolated from the lung compartment and the blood to release the major neutrophil pro- and anti-inflammatory cytokines IL-8 and IL-1-receptor antagonist (ra) spontaneously and in the presence of LPS. Comparison of cytokine production by blood neutrophils from CF patients and from control subjects showed significantly increased IL-8 and decreased IL-1ra release by CF neutrophils. Comparison of cytokine production by airway and blood neutrophils from CF patients also documented distinct profiles: the spontaneous release of IL-8 and IL-1ra by airway neutrophils was significantly higher than that from blood neutrophils. Culture in the presence of LPS failed to further enhance cytokine production. Analysis of the effect of dexamethasone confirmed the difference in the responsiveness of lung and blood neutrophils in CF. Used at a concentration effective in reducing IL-8 production by blood neutrophils, dexamethasone (10(-6) M) was unable to repress secretion of IL-8 by airway neutrophils. In addition, comparison of cytokine production by airway neutrophils from children with CF and children with dyskinetic cilia syndrome also documented distinct profiles of secretion. These results are consistent with a dysregulated cytokine production by lung and blood neutrophils in CF. They provide support to the hypothesis that not only the CF genotype but also the local environment may modify the functional properties of the neutrophils.

To understand the dynamics of the intraarticular acute inflammatory phase of an anterior cruciate ligament (ACL) injured knee, we analyzed the level of inflammatory cytokines (TNF-alpha, IL-1beta, IL-6, IL-8, IL-1ra, and IL-10) in joint fluid samples aspirated from 34 knees following an acute ACL injury. The samples were divided into the following five groups according to the duration from injury to aspiration: within 24 h (n=5), 2-3 days (n=14), 4-6 days (n=5), 7-9 days (n=5), 10-14 days (n=4), and 15-21 days (n=3). For comparison, 7 samples were also aspirated from 4 patients with osteoarthritis and 3 with postmenisectomy hydrops (chronic arthritis group). The highest levels of inflammatory cytokines were detected in the ACL-injury group within 24 h of the injury, and the levels decreased thereafter. While there were several patterns of decrease, nearly all of the inflammatory cytokines decreased to the level of that in the chronic arthritis group within 1 week. These dynamics are similar to those reported for inflammatory cytokines in wound fluid during wound healing, and suggest that the intraarticular healing process also progresses in ACL injured knees.

Migratory pattern of schistosomula of Schistosoma mansoni, S. haematobium, and S. japonicum through human skin were analyzed in skin organ cultures. These studies showed that the schistosomula of S. mansoni and S. haematobium has similar migratory patterns through human skin. During the first 24h after infection nearly 90% of S. mansoni and S. haematobium schistosomula were present only in the epidermis. Majority of the schistosomula were found in the dermis only after 48h and they appear to reach the dermal vessels around 72h after infection. Migratory pattern of S. japonicum on the other hand was significantly different from the other two species in that over 90% of the parasites had already reached the dermis within the first 24h and schistosomula were present in the dermal vessels within 2h after infection. Analysis of the cytokine pattern at 8h after infection by a macro gene array and RT-PCR analysis showed that out of 24 different cytokines analyzed only IL-1ra, IL-10, and TNF-alpha were increased in the human skin following infections with S. mansoni and S. haematobium, whereas, after infection with S. japonicum there was significant increases in IL-1beta, IL-1ra, IL-2, IL-6, IL-8, IL-10, IL-15, IL-18, and TNF-alpha. Immunohistochemical analysis of epidermal sheets showed focal accumulation of HLA-DR(+) cells in areas where schistosomula of S. mansoni had entered the human skin.

The small bowel is an important dose-limiting organ in abdominal radiotherapy because irradiation can cause acute enteritis that, in turn, leads to progressively reduced motility and finally, in a later phase, to fibrosis. Because these clinical symptoms may be caused by the early stage of an inflammatory process, we characterized the radiation-induced intestinal inflammation in rats. Abdominal gamma-irradiation (10-Gy) induced a cascade of inflammatory events characterized by an early (6 h after exposure) increase in IL-1beta, TNF-alpha, and IL-6 mRNA levels in the rat ileal muscularis layer. IL-8 [a cytokine-induced neutrophil chemoattractant (CINC)] mRNA appeared later (at 3 days). The expression of TGF-beta (a profibrotic cytokine) was higher in irradiated than control tissue at day 1, whereas IL-10 (an anti-inflammatory cytokine) expression vanished completely. Despite strong IL-1ra expression, the IL-1ra/IL-1beta ratio, which is an indicator of inflammatory balance, was -41% at day 1 in irradiated compared with control tissue. The nuclear transcription factors NF-kappaB and activator protein-1 (AP-1) govern transcription of these genes, directly or indirectly. Although expression of the subunits of NF-kappaB (p65, p50) and AP-1 (c-fos, c-jun) did not increase, irradiation caused a rapid and persistent translocation of p65 and p50. An imbalance between proinflammatory and anti-inflammatory mediators may contribute to perpetuating intestinal inflammation, thus making it chronic.

Changes in immune and oxidative stress parameters were measured in ultramarathon runners competing in the 160-km Western States Endurance Run. Forty-five runners agreed to provide blood and saliva samples the morning before the race event, at the 90-km aid station, and 5 - 10 min post-race. Upper respiratory tract infection (URTI) during the two-week period post-race was assessed retrospectively by telephone interviews. Forty subjects completed 90-km (race time, 13.1 +/- 0.3 h), and 31 completed the 160-km race event (27.0 +/- 0.4 h). The blood neutrophil and monocyte counts rose 249 % and 214 %, respectively, in the 31 finishers. Salivary IgA (sIgA) secretion rate decreased significantly from 508 +/- 40 micro g/min pre-race, to 287 +/- 39 micro g/min at 90-km, and 254 +/- 30 micro g/min post-race (50 % decrease). Significant increases were measured in cytokines at 90-km and post-race, with post-race IL-10 increasing 9.5-fold, IL-1ra 6.1-fold, IL-6 50.2-fold, and IL-8 2.5-fold over pre-race levels. Post-race indicators of oxidative stress, F (2)-isoprostane and lipid hydroperoxides, increased 33 % and 88 %, respectively. Pearson product-moment correlations revealed positive correlations at 90-km between F (2)-isoprostane and IL-6 (r = 0.31, p = 0.048), IL-10 (r = 0.31, p = 0.050), and IL-8 (r = 0.43, p = 0.005), but no other significant relationships between immune and oxidative stress indicators at 90-km and post-race. In the group of runners completing at least 90 km of the race, 26 % reported an URTI episode during the two-week period post-race. A low sIgA secretion rate at 90-km was the best predictor of post-race URTI (173 +/- 34 micro g/min in those who later acquired URTI compared to 325 +/- 40 micro g/min in those without URTI, p = 0.007). In conclusion, a modest correlation was found between cytokines and F (2)-isoprostane at 90-km when the greatest oxidative stress occurred, but no other significant correlations in immune and oxidative stress indicators during and following a 160-km ultramarathon race event were noted. About one in four ultramarathoners reported URTI during the two-week period post-race, and a low sIgA secretion rate mid-race best predicted URTI occurrence.

Helicobacter pylori (HP) infection elevates the risk of gastric diseases including peptic ulcer and gastric cancer. The infection induces inflammatory cytokines, which could work both for and against lifetime infection in the human stomach. Genetic polymorphisms of the cytokines and other related ligands, receptors, and enzymes may influence persistent HP infection. This paper summarizes studies done on the associations between anti-HP antibody seropositivity and polymorphism genotypes. To date, the associations with the polymorphisms of fucosyl transferase 2 (FUT2 or secretor gene), FUT3 (Lewis gene), interleukin 1A (IL-1A), IL-1B, IL-1RN, IL-8, IL-10, myeloperoxidase (MPO), and tumor necrosis factor A (TNF-A) and TNF-B have been reported. Polymorphisms of other related genes, CD14, CXC chemokine receptor 2 (CXCR2), IL-1RI, nuclear factor KB2 (NF-KB2), and Toll-like receptor 4 (TLR4), have the potential to influence persistent infection. Unpublished results from our datasets are reported here for all these polymorphisms except TLR4. Gene-environment interactions between these genotypes and smoking are reviewed. An effect on OR due to the involvement of unexposed subjects is demonstrated to elucidate a disadvantage in the studies done in areas where the majority of the population is not exposed to HP.

Inactivated parapoxvirus ovis (Orf virus; PPVO) recently displayed strong immunostimulating and modulating capacities in several animal models for acute and chronic virus infections through the induction of gamma interferon (IFN-gamma) as a key mediator of antiviral activity. The data presented in this work demonstrate that inactivated PPVO has strong effects on cytokine secretion by human immune cells, including the upregulation of inflammatory and Th1-related cytokines (IFN-gamma, tumor necrosis factor alpha [TNF-alpha], interleukin 6 [IL-6], IL-8, IL-12, and IL-18) as well as anti-inflammatory and Th2-related cytokines (IL-4, IL-10, and IL-1 receptor antagonist [IL-1ra]). Studies on the mechanism of action revealed virus particles to be the effective components of the preparation. The virus particles activate monocytes or other antigen-presenting cells (APC), e.g., plasmacytoid dendritic cells, through signaling over CD14 and a Toll-like receptor and the intracellular presence of certain PPVO-specific components. The activation of monocytes or APC is followed by the release of early proinflammatory cytokines (TNF-alpha, IL-6, and IL-8) as well as the Th1-related cytokines IL-12 and IL-18. Both IL-18 and IL-12 are involved in PPVO-mediated IFN-gamma release by T cells and/or NK cells. The proinflammatory response is accompanied by the induction of anti-inflammatory and Th2-related cytokines (IL-4, IL-10, and IL-1ra), which exert a limiting efffect on the inflammatory response induced by PPVO. We conclude that the induction of a natural immune response with physiologically significant amounts of different cytokines and with antiviral potential might provide advantages over existing antiviral immunotherapies.
