Abstract
PROBLEM The aim of this meta-analysis was to evaluate whether specific maternal HLA alleles and HLA sharing of couples are associated with the occurrence of recurrent miscarriage (RM). METHOD OF STUDY A systematic literature search was performed for studies that evaluated the association between HLA alleles, HLA sharing and RM. RM was defined as three or more consecutive unexplained miscarriages and a control group was included of women with at least one live birth and no miscarriages in their history. Meta-analyses were performed and the pooled odds ratio (OR) was calculated. RESULTS We included 41 studies. Selection bias was present in 40 studies and information bias in all studies. Meta-analyses showed an increased risk of RM in mothers carrying a HLA-DRB1*4 (OR 1.41, 95% CI 1.05-1.90), HLA-DRB1*15 (OR 1.57, 95% CI 1.15-2.14), or a HLA-E*01:01 allele (OR 1.47, 95% CI 0.20-1.81), and a decreased risk with HLA-DRB1*13 (OR 0.63, 95% CI 0.45-0.89) or HLA-DRB1*14 (OR 0.54, 95% CI 0.31-0.94). Pooling results for HLA sharing showed that HLA-B sharing (OR 1.39, 95% CI 1.11-1.75) and HLA-DR sharing (OR 1.57, 95% CI 1.10-1.25) were both associated with the occurrence of RM. CONCLUSION Although the present systematic review and meta-analysis demonstrates that specific HLA alleles and HLA sharing are associated with RM, a high degree of bias was present and therefore observed results should be interpreted carefully.

Gestational dermatosis shortly after implantation associated with parental class II HLA compatibility and maternal immune activation: preliminary report of a prospective case series.

Abstract
BACKGROUND Pregnancy represents a semi-allograft, subject to similar immune responses as allogeneic organ transplants. Tolerance of pregnancy appears best with maximal class II HLA heterogeneity between mother and father, while compatibilities are associated with increased pregnancy loss and maternal autoimmunity. Tolerance abnormalities often involve skin reactions. Abnormalities in tolerance of the fetal graft may do the same. OBJECTIVE To define the characteristics of a newly described dermatosis in very early pregnancy. METHODS Prospective case series of 7 couples/12 clinical episodes. RESULTS The dermatosis was observed in 7 out of 285 women undergoing in vitro fertilization (IVF; 2.5%; 95% CI 0.66-4.26%) and in 12 out of 277 total IVF cycles reaching embryo transfer (4.3%; 95% CI 1.93-6.73%). Prior to IVF all women reported autoimmune clinically significant allergies. All but 1 couple demonstrated class II HLA compatibility. Two of 4 pregnancies miscarried. All rashes erupted within days from embryo implantation. CONCLUSIONS The 'implantation rash' reported here is uncommon but not rare. It may be the consequence of abnormal maternal immune responses to embryo implantation in women with prior immune activation, associated with class II HLA compatibility between parents. Further prospective studies are required to better define this condition.

Abstract
BACKGROUND In this study, recurrent miscarriages (RMs) are defined as loss of two or more clinically detectable pregnancies before 20 weeks of gestation. HLA has been thought to play a role in RM. However, the results of earlier studies on the role of different human leucocyte antigen (HLA) genes were conflicting and inconclusive. In the present study, we investigate HLA genes (HLA-DRA, HLA-DRB1, HLA-DQA1 and HLA-DQB1) in RM couples with unknown etiology and normal couples. METHODS Blood samples from 143 RM couples and 150 control couples were analyzed, firstly to validate previously reported association studies and secondly to explore whether any novel alleles or haplotypes specific to Indian populations can be observed to be associated with RM. HLA typing was carried out by DNA sequencing. RESULTS Results suggest an association of the DQB1*03:03:02 allele with RM (odd ratio = 2.66; p(c) = 0.02; confidence interval = 1.47-4.84). Haplotypes of the DQA1 and DQB1 risk alleles also showed a significant association with RM, albeit not after Bonferroni correction for multiple comparisons. CONCLUSIONS HLA-DQB1 appears to have a strong involvement in the manifestation of RM in this population from South India. The current genetic analysis of RM and control couples not only highlights the genes exhibiting a strong etiological role but also reflects the protective nature of some HLA genes against RM. Nevertheless, most of these alleles/haplotypes were not those that are implicated in RM in other ethnic backgrounds, and hence require further validation in other populations of India, from different ethnic and/or geographic backgrounds.

Abstract
The aim of the study was to investigate whether human leukocyte antigen (HLA) allele sharing between partners or the maternal killer immunoglobulin-like receptor (KIR) repertoire is associated with recurrent spontaneous abortion (RSA) and repeated implantation failure after in vitro fertilization (IVF)/embryo transfer. From a total population of 158 RSA couples, 40 couples with repeated implantation failures (IVF) and 81 control couples, reported by five different laboratories, analysis was performed for (a) HLA sharing in 50 RSA, 31 IVF and 31 control couples, (b) DQA1*0505 sharing/homozygosity among partners in 108 RSA, 40 IVF and 36 control couples, and (c) the women's KIR repertoire in 46 RSA, 26 IVF and 36 control wives. RSA couples were divided into alloimmune aborter (RSAallo) and autoimmune aborter (RSAauto). The results oppose to the suggestion that increased HLA sharing per se or a limited maternal KIR repertoire predisposes to RSA or IVF failure. However, the observation of a slightly higher percentage of DQA1*0505 sharing in the RSAauto and the IVF group needs further investigation. The ratio of inhibitory to activating KIR (actKIR) was slightly lower in RSAallo and IVF women (1.9 vs 2.6 in controls), while in a high percentage of these women, the standard receptors of the KIR A haplotype were combined with actKIR/s of the haplotype B (66.6% and 45.4% vs 20% and 15.3% in RSAauto and control groups). This may suggest a possible involvement of actKIRs in embryo implantation and the maintenance of pregnancy and also requires further investigation.

Abstract
It is hypothesized that patients having unexplained recurrent miscarriage lack an appropriate immune reaction against their partner's antigens, which means possible compatibility of HLA antigens between the patient couples. The conclusion, however, has not yet been achieved, so the purpose was to determine whether significant compatibility of HLA class II exists between the couples. The HLA-DRB1 and -DQB1 genotypes were determined using PCR-RFLP method in 91 patient couples and in 72 normal couples. The number of patient couples with zero-allele mismatch was not significantly different compared with that of control couples regarding HLA-DRB1 genotype and phenotype, as well as regarding HLA-DQB1 genotype and phenotype. While the number of patient couples with zero- and one-allele mismatch was significantly higher compared with that in control as to HLA-DR and -DQ phenotype (P=0.029 by Chi-square test). In conclusion, it is suggested that the compatibility of HLA class II antigens between couples might be involved in the genesis of unexplained recurrent miscarriage.

Abstract
An estimated 15% of clinically recognized pregnancies abort spontaneously. Recurrent spontaneous abortion (RSA) is defined as three or more consecutive miscarriages conceived with the same partner in the absence of uterine, genetic or autoimmune abnormalities. Evidence points to human leucocyte antigens (HLA) as playing a role in the successful development of the foetus. In particular, HLA compatibility is more prevalent in couples experiencing reproductive failure, especially RSA couples, compared to fertile couples. According to the immunological hypothesis, an adequate immune response is necessary for proper implantation of the embryo; conversely, a depressed response of maternal lymphocytes to the stimulation by paternal antigens because of HLA sharing can result in disorders, such as RSA. The genetic hypothesis implicates homozygosity for recessive lethal alleles in linkage disequilibrium with specific HLA haplotypes. The specificity of HLA alleles or haplotypes responsible for or linked to other RSA susceptibility genes remains unclear. In this study, we identified 40 observational studies (32 case-control, five cohort, one cross-sectional, one case series and one basic science) that examined the associations between HLA and RSA, focusing on HLA allele couple and maternal-foetal sharing, and the special role of HLA-G. We sought to identify consistent findings among studies examining similar questions. Evidence remains divided concerning the role of HLA allele couple sharing. Of major concern is the focus of many studies on couple sharing as a proxy measure of maternal-foetal sharing. Therefore, adequately powered studies are needed, which employ standard case definitions and reproducible methodologies to directly assess the role of maternal-foetal HLA sharing on the risk of RSA.

Abstract
In order to clarify the genetic background of recurrent spontaneous abortion, the frequency of HLA-A, -B, and -C alleles was analyzed in eighty-nine patients with a history of unexplained primary recurrent abortion. The frequency of each HLA-A, -B, and -C antigen allele was calculated in patients with recurrent abortion and their husbands, and compared with the frequencies in the general population represented by 207 individuals in the Niigata district of Japan. The incidence of individuals homozygous for the HLA-A, -B, and -C alleles was also compared between the patient group and the control group. The frequency of HLA-B35 in the patient group (5 of 89, 5.6%) was significantly lower than in the general population (40 of 207, 19.3%) (Odds Ratio, 0.25; 95% Confidence Interval, 0.09-0.65; P < 0.005; Pc, not significant). The frequencies of other HLA-A, -B, and -C alleles were not significantly different between the patient group and the general population. No significant difference in the frequency of HLA-A, -B, and -C alleles was observed between the husband group and the general population. The incidence of individuals homozygous for HLA-A, -B, or -C alleles in the patient group was not significantly different from the general population. The significantly lower frequency of HLA-B35 in patients with unexplained recurrent abortion suggests that the Th2-associated immune reactions may be lacking in such patients, as it has been reported that an enhanced Th2 response in conjunction with a decreased T Th1 response is a common immune reaction in HLA-B35-positive individuals.

Abstract
PROBLEM To clarify whether HLA-DP antigens are associated with patient population of unexplained recurrent abortion. METHOD OF STUDY The frequency of HLA-DPB1 alleles in patients with unexplained recurrent abortion, and the compatibility of HLA-DPB1 alleles between patient couples, were studied using a polymerase chain reaction (PCR)-restricted fragment length polymorphism (RFLP) method. Thirty patients who had a history of unexplained primary recurrent abortion, and their husbands, were typed for HLA-DPB1 genotype. Two hundred and ninety-nine base pair fragments from the second exon of HLA-DPB1 genes were selectively amplified using the PCR-primers. After amplification, the DNAs were digested with restriction endonucleases, and subjected to electrophoresis in a 12% polyacrilamide gel to determine HLA-DPB1 genotype. RESULTS The frequency of HLA-DPB1*0402 and DPB1*04 alleles in the patient group (n = 30) was significantly increased, as compared to that in the normal fertile women (n = 30). The frequency of HLA-DPB1*04 allele in the patient group was significantly increased, as compared to that in the general population (n = 112). No significant compatibility of HLA-DPB1 alleles could be observed between patient couples and normal fertile couples. CONCLUSION These findings suggest a possible new class II association with patient population of unexplained recurrent abortion.

Abstract
PROBLEM The influence of HLA sharing on pregnancy outcome is controversial. In renal transplantation, HLA-DQB1 donor-recipient mismatches have been shown beneficial for long-term transplant success. Since pregnancy is defined as Nature's allograft, we investigated the relevance of HLA-DQ mismatching in normal reproducing couples compared to couples experiencing RSA. METHOD Unexplained RSA couples referred to our laboratory for immunological testing were classified by immunological findings and obstetrical history. Primary RSA couples shared > or = 2 HLA-A, B, or DR antigens, had no cytotoxic anti-paternal antibodies, and no gestation beyond 20 weeks. Secondary RSA couples had cytotoxic anti-paternal antibodies and RSA after a live birth. HLA-DQA1 and DQB1 alleles were identified by PCR-SSP. RESULTS No differences in DQA1 and DQB1 mismatch were observed among RSA patients and controls. DQA1-DQB1 haplotype mismatches were not different among the three groups of couples. CONCLUSIONS In contrast to renal transplant, HLA-DQ incompatibility did not differ among RSA couples compared with successful reproducing couples.

Abstract
Using the "Polymerase Chain Reaction-Sequence Specific Oligoprobes" (PCR-SSOp) technique, we studied the HLA-DPB locus in both partners of 59 couples with a history of three spontaneous abortions, and of 38 control couples in order to determine the role of this centromeric region of the major histocompatibility complex (MHC) in the immune reaction needed for a favorable course of pregnancy. As no particular phenotypes were noted, and also neither excessive HLA-DP homozygosity in sterile women nor excessive HLA-DP allele sharing between sterile partners, this MHC class II sub-region would seem to play no role either directly or by linkage disequilibrium, in the development of normal pregnancy.
