BACKGROUND Recurrent fetal loss (RFL) is a prevalent problem affecting ~1% of all women of childbearing age. Many factors can lead to RFL; however, recent studies have indicated the important role of the maternal immune system in this process. The human leukocyte antigens (HLA), HLA-linked genes and regulatory factors play an important role in fetal loss and in fetal development. The current retrospective study was preformed to examine the HLA alleles shared between couples with RFL in Saudi Arabia, using a large cohort of women (having three or more RFL). Specific HLA alleles that could influence this condition, or the number of miscarriages experienced, were expected to be highlighted in this way. METHODS A total of 253 consecutive patients who visited the RFL clinic at the King AbdulAziz Medical City, National Guard Hospital in Riyadh were included in this study. They included 54 consanguineous couples, 132 non-consanguineous couples and another 67 couples shared only their tribal origin. Clinical examinations as well as laboratory investigations were carried out on each patient. Class I HLA, HLA-A, HLA-B and HLA-C, and Class II HLA, HLA-DR and HLA-DQ, were typed for each patient and their partner. RESULTS No relationship was seen between sharing of HLA alleles and the number of RFL experienced by the couples, among neither consanguineous nor non-consanguineous couples. CONCLUSIONS Although the results of this study suggest that HLA sharing is not an indicative factor in RFL, definitive conclusions on this topic must be based on large case–control studies.
