Abstract
We report the case of a 76-year-old female with diffuse large B cell lymphoma who developed tumor lysis syndrome (TLS) and subsequent acute kidney injury (AKI) due to massive hyperphosphatemia during the prophylactic use of rasburicase. Our case showed no hyperphosphatemia before chemotherapy but had elevated uric acid and creatinine levels and unilateral hydronephrosis due to paraaortic lymphadenopathy. TLS risk was classified as high risk because of bulky mass, LDH elevation, and renal disturbance. With rasburicase use, uric acid was completely controlled but massive hyperphosphatemia and, subsequently, AKI developed. Immediate kidney replacement therapy led to improvement of hyperphosphatemia and AKI. In the rasburicase era, hyperphosphatemia has been a key target for preventing and treating TLS. Renal replacement therapy is the only effective option for lowering hyperphosphatemia and treating AKI.

Abstract
Decreasing graft rejection and increasing graft and patient survival are great challenges facing liver transplantation (LT). Different T cell subsets participate in the acute cellular rejection (ACR) of the allograft. Cell-mediated immunity markers of the recipient could help to understand the mechanisms underlying acute rejection. This study aimed to analyse different surface antigens on T cells in a cohort of adult liver patients undergoing LT to determine the influence on ACR using multi-parametric flow cytometry functional assay. Thirty patients were monitored at baseline and during 1 year post-transplant. Two groups were established, with (ACR) and without (NACR) acute cellular rejection. Leukocyte, total lymphocyte, percentages of CD4+ CD154+ and CD8+ CD154+ T cells, human leukocyte antigen (HLA) mismatch between recipient-donor and their relation with ACR as well as the acute rejection frequencies were analysed. T cells were stimulated with concanavalin A (Con-A) and surface antigens were analysed by fluorescence activated cell sorter (FACS) analysis. A high percentage of CD4+ CD154+ T cells (P = 0·001) and a low percentage of CD8+ CD154+ T cells (P = 0·002) at baseline were statistically significant in ACR. A receiver operating characteristic analysis determined the cut-off values capable to stratify patients at high risk of ACR with high sensitivity and specificity for CD4+ CD154+ (P = 0·001) and CD8+ CD154+ T cells (P = 0·002). In logistic regression analysis, CD4+ CD154+ , CD8+ CD154+ and HLA mismatch were confirmed as independent risk factors to ACR. Post-transplant percentages of both T cell subsets were significantly higher in ACR, despite variations compared to pretransplant. These findings support the selection of candidates for LT based on the pretransplant percentages of CD4+ CD154+ and CD8+ CD154+ T cells in parallel with other transplant factors.

Abstract
Introduction Hypnosis is a therapeutic strategy for pain control. We aimed at investigating the use of this technique in a large population undergoing atrial fibrillation (AF) ablation. Methods 70 consecutive AF patients referred for transcatheter ablation, underwent hypnotic communication for periprocedural analgesia (Group A), were compared with 70 patients undergoing conventional analgesia (Group B). Procedural data, anxiety, perceived pain, perceived procedural duration and the dosages of administered analgesic drugs were compared using validated score scales. Results Hypnotic communication (Group A) resulted in a significant procedural-related anxiety reduction (Pre procedural 4.7 ± 2.9 Vs Intra Procedural 0.8 ± 1.2, P < 0.001) and perceived procedural duration (Real length 108 ± 33 min Vs Perceived Length 77 ± 39 min, P < 0.001). Group A patients reported a painless procedure in 78% (Pain scale ≤2). Regarding analgesic drug, Group A used only Fentanyl and Paracetamol. The Fentanyl dosage was similar in Group A and B (mean 0.142 Vs 0.146 mg, P = 0.65) while higher Paracetamol dosage was reported in Group A (mean 853 Vs 337 mg, P < 0.001). Group B also used Midazolam (mean 1.8 mg), Propofol (mean 43.8 mg) and narcosis was required in 2 patients. Total radiofrequency (RF) delivered time did not differ between the two groups (mean 28.9 Vs 27.6 min, P = 0.623) as well as mean RF power (mean 35.3 Vs 35.5 W, P = 0.424). No complications occurred. Conclusion Hypnotic communication during AF ablation was related to a significant reduction of intra-procedural anxiety, perceived pain, procedural analgesic drugs dosage and perceived procedural duration without affecting total RF delivered time and procedural safety.

Abstract
An important factor affecting the success in the setting of related haploidentical hematopoietic stem cell transplantation (HSCT) is the graft-versus-leukemia effect mediated by natural killer (NK) cells when the donor displays NK alloreactivity versus the recipient. NK cell function is regulated by killer immunoglobulin-like receptors (KIR) and it has been described that donor KIR genotype influences transplantation outcome. This has led to a requirement of laboratories to have a quality assurance program for validation and control of their KIR genotyping methods. The goal of the 1st and 2nd Spanish KIR Genotyping Workshops was to provide an external proficiency testing program in KIR genotyping for Spanish immunology and transplant laboratories. These workshops were conducted during the years 2014-2016 and consisted of 17 participating laboratories typing a set of 20 samples. The presence/absence of 16 mandatory KIR loci (2DL1, 2DL2, 2DL3, 2DL4, 2DL5, 2DS1, 2DS2, 2DS3, 2DS4, 2DS5, 2DP1, 3DL1, 3DL2, 3DL3, 3DS1, and 3DP1) was evaluated per sample. Methods for KIR genotyping included polymerase chain reaction with the use of sequence-specific primers and sequence-specific oligoprobes. Consensus typing was reached in all samples, and the performance of laboratories in external proficiency testing was satisfactory in all cases. The polymorphism detected in the small sample studied in both workshops is indicative of an ample variety of KIR gene profiles in the Spanish population.

Abstract
Anti-inflammatory cytokines have an important role in disease, tumour and transplant processes. Alterations in the regulation of several cytokines have been implicated in a variety of inflammatory disorders, including IBD (inflammatory bowel disease) [Crohn's disease (CD) and ulcerative colitis (UC)]. Cytokine polymorphisms are also known to affect the level of gene expression. Thus, the aim of this study was to determine the relationship between cytokine polymorphisms and the IBD pathologies in a Spanish population. Polymorphisms analysis was performed using PCR-SSOP using a microbeads luminex assay. The following polymorphisms were determined: TNFα [-238G/A (rs361525) and -308G/A (rs1800629)], IFNγ [+874A/T (rs62559044)], TGFβ [+869C/T (rs1982073) and +915G/C (rs1800471)], IL10 [-1082A/A (rs1800896), -592A/C (rs1800872), -819C/T (rs1800871)], IL6 [-174C/G (rs1800795)], IL12p40 [3'UTR -1188A/C (rs3212227)], IL1α [-889C/T (rs1800587)], IL1β [-511C/T (rs1143634) and +3962C/T (rs1143633)], IL1R [Pst-1 1970C/T] and IL1RA [Mspa-1 11100C/T]. No statistical differences in TNFα, IFNγ, TGFβ, IL10, IL6, IL1α, IL1β, IL1R and IL1Ra genotypes and allele distributions between the IBD groups and healthy controls were found. However, we observed significant differences in the 3'UTR -1188A/C polymorphism of IL12p40. So -1188A allele was increased in patients with UC and the -1188C allele (high IL12p40 production) was increased in patients with CD with respect to controls. These data are in concordance with the fact that CD has been shown to be associated with a Th1 T-cell-mediated inflammation model and high IL12/IFNγ production at histological affected sites. These data suggest that cytokine polymorphisms in TNFα, IFNγ, TGFβ, IL10, IL6 and IL1α, IL1β, IL1R and IL1Ra cytokine gene do not seem to be relevant in IBD susceptibility and IL12p40 3'UTR -1188A/C polymorphism seems to be associated with a differential IBD development.

Abstract
Although flood risk perceptions and their concomitant motivations for behaviour have long been recognised as significant features of community resilience in the face of flooding events, there has, for some time now, been a poorly appreciated fissure in the accompanying literature. Specifically, rationalist and constructivist paradigms in the broader domain of risk perception provide different (though not always conflicting) contexts for interpreting evidence and developing theory. This contribution reviews the major constructs that have been applied to understanding flood risk perceptions and contextualises these within broader conceptual developments around risk perception theory and contemporary thinking around flood risk management. We argue that there is a need to re-examine and re-invigorate flood risk perception research, in a manner that is comprehensively underpinned by more constructivist thinking around flood risk management as well as by developments in broader risk perception research. We draw attention to an historical over-emphasis on the cognitive perceptions of those at risk to the detriment of a richer understanding of a wider range of flood risk perceptions such as those of policy-makers or of tax-payers who live outside flood affected areas as well as the linkages between these perspectives and protective measures such as state-supported flood insurance schemes. Conclusions challenge existing understandings of the relationship between risk perception and flood management, particularly where the latter relates to communication strategies and the extent to which those at risk from flooding feel responsible for taking protective actions.

Abstract
BACKGROUND There is no consensus about the impact of thresholds of complement-fixing antibody assays. Recently, a C1q-SAB assay has been developed to identify complement-fixing HLA antibodies with high sensitivity and specificity. Our aim was to determine the correlation between IgG single antigens beads (SAB) and C1q-SAB assay results among patients on the renal waiting list. PATIENTS AND METHODS Serum samples from immunized renal waiting list patients as well as negative and positive controls were valided by Luminex (LMX). These sera, which were positive for 166 antibody specificities, were tested for HLA class I in parallel by LMX-IgG and LMX-C1q. RESULTS Comparison of antibody detection revealed no correlation based on median fluorescent intensity (MFI), levels between the IgG SAB and the C1qSAB assay (P > .05). IgG-positive sera with MFIs as low as 700 were able to fix C1q, whereas other sera with MFIs as high 14,500 did not. Furthermore, there appeared to be disparities in the profiles of class I antigens able to fix C1q-SAB. In our series, only 34% class I IgG SAB antibodies were also C1qSAB+. In several patients, we detected C1qSAB+ against IgGSAB- that was surely due to IgM antibodies. So, the C1qSAB assay detected IgM antibodies that fix complement. CONCLUSION These data suggested that the C1q-SAB assay could be an important method to evaluate pretransplant virtual crossmatch and to define nonpermitted specificities (C1q-fixing) in kidney transplantation.

Abstract
Tumour necrosis factor alpha (TNF-α) has an important role in inflammatory response. Alterations in the regulation of TNF-α have been implicated in a variety of inflammatory disorders, including Inflammatory bowel disease (IBD). Indeed, a common treatment for IBD is the use of TNF-α inhibitors. Polymorphisms in the TNF-α promoter region are known to affect the level of gene expression. Our aim was to investigate the influence of these single nucleotide polymorphisms (SNPs) in TNF-α promoter gene play in the risk of IBD in a Spanish population and their individual response to anti-TNF-α treatment. DNA samples from patients with IBD and controls were screened for TNF-α -238G/A (rs361525) and -308G/A (rs1800629) SNPs by PCR-SSOP using a microbeads luminex assay and compared with response to TNF-α inhibitors. There were not statistical differences in -238G/A and -308G/A allele and genotype frequencies between patients. However, we found an increased frequency of -308A allele and -308GA genotype in these nonresponders patients to TNF-α inhibitors with respect to responders patients (Pc < 0.05). This -308GA genotype has been classified as high producer of this cytokine. This fact could actually be interesting to explain the different response of patients with IBD with respect to TNF-α inhibitors. TNF-α promoter gene polymorphism does not seem to play a role in IBD susceptibility, but particular TNF-α genotypes may be involved in the different responses to TNF-α inhibitor treatment in Spanish patients with IBD.

Abstract
A 55-year-old man underwent rectal amputation for rectal cancer in August 2005. A tiny thin-walled cavity lesion in his left S1+2 was found on computed tomography (CT) of the chest in November 2008. The cavity lesion in the left S1+2 gradually increased in size over 3 months and positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) showed FDG accumulation at the lesion. Videoassisted thoracoscopic (VATS) wedge resection was performed to make a definite diagnosis in March 2009. The pathological findings revealed a metastatic lung tumor from the rectal cancer. It is necessary to consider the possibility of metastatic lung tumors in a case with the cavity lesions especially in patients with a history of colon cancer.

Abstract
Co-stimulatory factors such as CD86 and apoptotic molecules such as CD95 and CD95L required to start and to turn off the allogenic immune response may also be present as soluble proteins. To determine the role of the soluble forms of CD86 (sCD86), CD95 (sCD95) and CD95L (sCD95L) in the outcome of liver transplants, we analyzed the circulating levels of these molecules in patients subjected to liver transplantation in the pre-operative period and during the first month post-transplantation. Serum samples were obtained from sixty-nine first orthotopic liver transplants (OLT). The patients were classified into acute rejection (AR=24) and not acute rejection (NAR=45), or considering the presence of chronic active hepatitis B or C (VP=30) or other primary liver diseases (VN=39). The levels of sCD86, sCD95 and sCD95L were analyzed by solid phase sandwich enzyme-linked immunoabsorbent assays. Our results first showed that the pre-transplantation serum levels of sCD86 in the AR group were significantly higher than in the NAR group (1007±82U/mL vs. 739±46U/mL, p=0.006), and in the post-transplantation period these levels decreased sharply. Second, the levels of sCD95L and sCD95 in the pre-transplantation period did not point to statistically significant differences between the AR and NAR groups. Considering primary liver disease, the pre-transplantation levels of sCD86 and sCD95L in the VP group were significantly higher than those of the VN group (VP, 977±69U/mL vs. VN, 722±51U/mL, p<0.002, and VP, 482±78pg/mL vs. VN, 221±31pg/mL, p=0.002, respectively). Multivariate analysis revealed that only the pre-transplantation levels of sCD86 were independently associated with the development of episodes of acute rejection (p=0.005, OR=2.1, IC 95%=1.27-3.47). In conclusion, the present work shows that primary liver disease could influence the pre-transplantation levels of sCD86 and sCD95L. High pre-transplantation serum levels of sCD86 could favor the development of episodes of acute rejection.

Abstract
Viral infections and cellular acute rejection (AR) condition immunosuppressive therapy and compromise the evolution of allografts. Immune monitoring can be useful for ascertaining rejection and for differentiating allo-reaction from activation induced by infections. This work analyzes the usefulness of monitoring the expression of CD28 and KIR2D receptors in peripheral blood T lymphocytes by flow cytometry, to ascertain the immune response in heart and liver transplant recipients. In both types of transplant, the up-regulation of CD28 in CD4(+) lymphocytes in the periods of greatest AR frequency indicates an effective allo-response, whereas the post-transplantation emergence of circulating CD8(+)CD28(-) and CD8(+)CD28(-)KIR2D(+) T cells correlates with better early clinical results. Cytomegalovirus (CMV) infection, but not hepatitis C virus (HCV) or other infections, abrogated both CD28 up-regulation and CD8(+)CD28(-)KIR2D(+) T-cell expansion. Our results show that monitoring the expression of CD28 and KIR2D receptors on T lymphocytes might be considered as sensors of the immune status of heart and liver recipients.

Abstract
CCL5/RANTES, a member of the C-C chemokine family, is a potent eosinophil, monocyte, basophile and lymphocyte chemo-attractant at the site of inflammation. Recent studies revealed that a functional mutation at the -403 position in the promoter may have significance for atopic dermatitis, bronchial asthma, sarcoidosis, rheumatoid arthritis and HIV infection, and others. Another polymorphism in the -28 position has been reported. Our objective was to investigate the possible influence of the CCL5/RANTES promoter polymorphisms in the different types of bronchial asthma. CCL5/RANTES genotyping was performed by polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) in 306 asthmatic patients with non-atopic (n = 145) and atopic (n = 161) asthma and 242 controls. The 81.9% of the atopic asthma patients for -403G/A had the G allele and the A allele frequency was 18%. Of the non-atopic asthma patients, the G allele frequency was 79.7% and the A allele was 20.3%. Concerning the -28C/G polymorphism, the frequency of the CCL5/RANTES -28G allele in our patients is 2.8%, which is similar to Spanish adult population. After comparing patients with asthma, atopic patients, non-atopic patients and control population, we found no significant deviation in the distribution of the alleles or genotypes of CCL5/RANTES promoter polymorphisms in any tested comparison. Therefore, human CCL5/RANTES gene promoter polymorphisms are not associated with the different types of bronchial asthma in Spanish population.

Abstract
During the rejection process of cardiac allografts, the expression of HLA antigens increases on various graft tissues, ie, the myocardium and the interstitial structures. However, in this type of transplant there is a paucity of knowledge about HLA expression on recipient cells, such as peripheral blood mononuclear cells. In the present study expression of HLA class I and class II antigens was monitored on peripheral blood lymphocytes prior to and during a 12-month follow-up, using flow cytometry. In our series, the frequency of acute rejection episodes was greater from the fourth to the ninth month after transplantation, coinciding with a reduction in cyclosporine blood levels. At the same time, expression of HLA class I and class II antigens significantly increased among recipients suffering from more severe acute rejection episodes compared with those showing acceptance of their grafts (P < .01). In conclusion, acute rejection episodes in cardiac transplantation were associated with up-regulation of HLA molecules on recipient peripheral blood cells. Monitoring the expression of HLA molecules on peripheral blood lymphocytes may represent an easy, noninvasive practice to individualize immunosuppressive therapy.

Abstract
The role of MICA antibodies in acute heart allograft rejection was examined utilizing 190 pre- and post-transplant serum samples from 44 patients collected during the first year after transplantation. MICA antibodies were detected by CDC test on recombinant cell lines and by the newly developed Luminex MICA antibody detection assay. Additionally, MICA expression was analyzed by 'real time' RT-PCR and by immunohistochemistry in 10 endomyocardial biopsies. Only two subjects had HLA antibodies post-transplant. Nevertheless, MICA antibodies were found in a significant number of subjects. The prevalence of MICA antibodies was significantly higher among those with severe acute rejection (AR) than in those without rejection (60.7% vs. 14.3%, p = 0.0038 by CDC; 55.5% vs. 5.7%, p = 0.0020 by Luminex). In most cases, the appearance of MICA antibodies post-transplant precedes AR. Following transplantation, MICA up-regulation correlated with histological evidence of severe rejection. Monitoring for MICA antibodies post-transplant may be useful to establish new risk factors for acute rejection.

Abstract
The Fas receptor is capable of transducing apoptotic cell death upon interaction with their ligand (FasL). Recent studies suggest that the Fas/FasL system is involved both in graft rejection and in transplantation tolerance. In this study, we analyzed the effect of Fas and FasL polymorphisms in liver allograft outcome. Fas and FasL polymorphisms were analyzed in 151 primary liver graft recipients. The Fas (-670 A/G) and the FasL (IVS2nt -124 A/G and IVS3nt 169 T/delT) polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism. Fas -1377 G/A polymorphism was determined by allele-specific amplification. Fas and FasL polymorphisms were not associated with acute and chronic rejection in liver transplant. In contrast, those recipients bearing the AA -670 Fas genotype showed significantly lower graft survival rate (S = 40%) than those bearing the GA genotype (S = 63.1%). These differences were detected from the first year post-transplant. Multivariate analysis confirmed that the AA genotype increased the risk of liver graft loss. This work suggests for the first time a possible harmful effect of Fas -670 AA genotype on liver graft survival, whereas the Fas and FasL polymorphisms are not associated with acute or chronic rejection in liver graft recipients.

Abstract
BACKGROUND Efficient T cell-APC interaction requires the participation of primary and co-stimulatory signals. The main co-stimulatory pathway involves the interaction of CD80 and CD86, expressed on the APCs, with their T cell counter-receptor, CD28 and CTLA-4. Recently, a G to A transition has been described at position +1057 of the CD86 gene, located in their cytoplasmic tail. METHODS CD86 polymorphism was analyzed by sequence based typing in DNA samples obtained from 205 liver transplant recipients. Acute rejection and chronic rejection were diagnosed based upon conventional clinical, biochemical and histological criteria. RESULTS The study of CD86 +1057 (G/A) polymorphism revealed that recipients bearing the A allele or the AA genotype have a reduced risk of acute rejection. In fact, the AA genotype was absent in the group of patients showing acute rejection episodes, whereas its frequency in those patients without acute rejection episodes was 8.8% (P=0.009, OR=0.07). This polymorphism did not reveal any association with the incidence of chronic rejection, but patients bearing the AA genotype showed a higher graft survival rate (83.3%) than those bearing the GA genotype (49.3%) or GG genotype (56.5%). CONCLUSIONS The results of the present report suggest that the CD86 AA genotype at +1057 position could be involved in liver transplant acceptance, given that its presence is related to a decrease of acute rejection frequency and to a graft survival increase.

Abstract
Although liver transplants show a special tolerogenic behaviour, rejection remains an important problem that involves several immunological mechanisms, some of which are unknown. Our study sought to analyze the influence of HLA-C polymorphism on short-term liver graft acceptance by HLA-C genotyping of 100 orthotopic liver transplant recipient-donor pairs. Recipients were statified according to the occurrence of acute rejection. HLA-Cw*06 allele appeared to be underrepresented among recipients without versus those with acute rejection or those in control groups. With regard to HLA-C allelic compatibility, the frequency of acute rejection or those in episodes decreased with fewer HLA-C mismatches. These findings suggest the participation of HLA-C molecules in liver graft alloresponses, involving HLA-C genotyping, as well as compatibility.

Abstract
Several authors have shown that anti-donor antibodies before liver transplantation are associated with decreased graft survival. The aim of this study was to investigate the relationship between anti-donor antibodies detected by the CDC technique or by FlowPRA, and acute or chronic rejection as well as graft survival. Furthermore, we sought to determine whether anti-donor antibodies, detected by the CDC technique, correlated with those discovered by cytometric screening. The acute rejection incidence among patients with complement-dependent cytotoxicity positive CDC cross-match was similar to that for patients with a negative cross-match. None of the patients with a positive cross-match developed chronic rejection. Allograft survival was significantly lower among recipients with a positive T-lymphocyte cross-match. Indeed, the majority of recipients with positive CDC cross-matches displayed graft failures before first posttransplant year. The results of a positive FlowPRA determination were concordant with a positive CDC cross-match in 85.71% of cases. Our data demonstrate that pretransplant FlowPRA correlates with the final CDC cross-match results. This finding suggests that in the future prospective pretransplant antibody screening with FlowPRA or CDC techniques may be useful to identify high-risk recipients.

Abstract
The immune response against melanoma can be influenced by cytokines with potentially opposite effects on tumour cell growth, such as interleukin-10 (IL10), interleukin-6 (IL6) and interferon-gamma (IFNgamma). Our objective in this study was to investigate whether polymorphisms in the regulatory regions of IL10, IL6 and IFNgamma genes are associated with the development of primary cutaneous melanoma and/or the prognosis of this tumour. We studied genotypic variations at positions -1082, -819 and -592 in the IL10 promoter, -174 in the IL6 promoter and +874 in the IFNgamma intron 1 in 42 melanoma patients and 48 healthy controls. These two populations showed very similar genotypic frequencies for IL10, IL6 and IFNgamma gene polymorphisms. There was a significant increase in the prevalence of IL10 low expression genotypes, specially the ACC/ATA genotype, among patients with a poorer prognosis. In contrast, IL6 promoter and IFNgamma intron 1 gene polymorphisms did not correlate with melanoma prognosis. These data indicate that investigation of polymorphisms in the regulatory regions of IL10, IL6 and INFgamma genes does not seem to be useful for predicting the risk of development of primary cutaneous melanoma. However, IL10 low expression genotypes may be associated with a poorer outcome in melanoma patients.

Abstract
We have analysed two Caucasian families in which recombinant individuals have been identified. In both families, initial low resolution typing of class I and II antigens of possible patients referred for bone marrow transplantation and their respective potential donors (based on inherited haplotypes analysis) revealed them to be HLA identical and supposedly inheriting-non-recombinant haplotypes. The mothers were found to be DRB1*04 generic allele homozygous, but possessing two DRB1*04 specific alleles, DRB1*0403 and DRB1*0404 (family A) and DRB1*0401 and DRB1*0402 (family B). In both cases the patients inherited a maternal haplotype that is the result of a recombination event between the mother's HLA-DRB1 and -B genes on their chromosomes. Based on linkage disequilibrium it is likely that the recombinant haplotypes are present in the patients rather than their brothers. In both families, the results of the MLC in terms of relative response was positive. Thus, these cases illustrate the importance of high resolution DNA class II typing when assignment of MHC antigens is of extreme importance (i.e. bone marrow transplantation).

Abstract
HLA-DQB1*0302 allele frequency is increased in liver graft recipients with acute rejection. We investigated polymorphism in the upstream regulatory regions (URRs) of the DQB1 gene to determine whether polymorphism in the DQB1 promoter region influences liver graft acceptance. A combination of typing protocols based on the polymerase chain reaction were used in 103 first-time liver transplants and 108 healthy Spanish controls. The QBP3.21 allele frequency and QBP3.21-DQB1*0302 haplotype were significantly different in recipients with acute rejection compared to those with good graft acceptance and to controls. Of major interest for acute rejection development are the promoter "splits" of DQB1*0302 (QBP3.21, QBP3.22, and QBP3.3 alleles), which are in linkage disequilibrium with DQB1*0302. The promoter splits were equally distributed in all groups. Thus, although there are significant differences in the frequencies of the QBP alleles and QBP-DQB1 haplotypes between recipients with and without acute rejection and controls, the composition of these haplotypes is essentially the same in all groups. In conclusion, our data show that the polymorphism in the DQB1 promoter region does not clearly influence liver graft acceptance, and, as occurs in other populations, QBP alleles exhibit strong linkage disequilibrium with the DQB1 locus.

Abstract
This study was conducted to establish reference values for percent oxygen saturation of hemoglobin (SaO2, %) and heart rate (HR, bpm) in children living at high altitude (4,100 m) and to relate possible differences in the variables with ethnic origin. Healthy children from a mine-located school (Tintaya, n = 417), a nearby school (Marquiri, n = 474), and a rural Andean community (Nuñoa, n = 373) were investigated. The samples included different ethnic combinations, with the Nuñoa children having a predominant Quechua ancestry. Mean SaO2 for all ages was substantially lower in all high altitude children compared to values considered normal for sea level. Among the three samples, SaO2 was higher (91.3 +/- 2.7) and HR was lower (84.8 +/- 13.6) in Nuñoa than in Tintaya (SaO2, 89.8 +/- 2.5; HR, 91.7 +/- 14.9) and Marquiri (SaO2, 89.6 +/- 3.1; HR, 88.5 +/- 12.9) (P < 0.05). There was no sex difference and only a weak age-dependent trend for SaO2. Values considered abnormal at sea level were observed in all healthy high-altitude children. Higher SaO2 and lower HR in Nuñoa children may suggest a better degree of acclimatization to altitude.
