Abstract: The autopsy records between 1980 and 1995 of 399 female rhesus monkeys (Macaca mulatta) at the Wisconsin Regional Primate Research Center were examined. Spontaneous endometriosis was found in 81 (20%) of the animals. The mean (+/- SD) ages at death for animals with and without endometriosis were 20.7 +/- 5.5 (range 10-35) and 13.4 +/- 7.7 (range 4-37) years respectively. Many of the animals had been exposed to experimental procedures, including laparoscopies, hysterotomies and oestradiol implants, and these were examined as possible risk factors for endometriosis. Of the 81 affected animals, 62 were matched to unaffected controls for age at death (to within 1 year) and year of death (to within 2 years) and the effect of various factors on the development of endometriosis was determined using conditional logistic regression. Exposure to three or more oestradiol implants or one or more hysterotomies were both significant risk factors, with estimated relative risks of 9.7 (95% confidence interval 2.5-37.2) and 5.8 (95% confidence interval 1.6-20.2) respectively. Animals that had been exposed to one or more laparoscopies showed no increased risk for developing endometriosis. These findings provide insight into the aetiology of the disease in women. ?2P51 4RR00167

Abstract: Linkage analysis can be problematic in humans because of the lack of large, multigenerational pedigrees and the difficulties in obtaining phenotypic data on all family members. In contrast, large, captive colonies of rhesus macaque are a potentially valuable resource for linkage studies because detailed phenotypic and genealogical data are kept, inbreeding is avoided, and DNA s les can usually be obtained. Microsatellite marker sets for genome-wide screening are available in a number of species, but not for the rhesus macaque. We tested primers to 400 human microsatellite markers from a genome-wide mapping set using DNA from nine unrelated female rhesus macaques. We found that 76 (19%) of the primers lified a polymorphic product using the standard protocols for human DNA. The average heterozygosity of the markers in humans was 0.80, compared to 0.65 in the rhesus macaques. This study provides preliminary data, which could be used toward the development of a linkage mapping set in this species. There would be a need, however, to confirm the Mendelian inheritance of the markers.

Abstract: Endometriosis occurs in several non-human primate species that have menstrual cycles. This study investigated the prevalence and familial aggregation of endometriosis in one of those species, the rhesus macaque. Between 1978 and 2001, 142 animals with endometriosis were identified from necropsy and surgical records and through the use of magnetic resonance imaging (MRI) at the Wisconsin National Primate Research Center, Madison, USA. All cases were used to build one large multigenerational pedigree and nine nuclear families comprising 1602 females in total. By 2002, the pedigrees contained 124 cases diagnosed at necropsy 17 at surgery and three at MRI. Female animals that had died aged > or = 10 years without endometriosis, had both ovaries until at least 1 year prior to death, and had a full necropsy, were considered unaffected. The prevalence of endometriosis among necropsied animals aged > or = 10 years in the colony was 31.4% [95% confidence interval (CI) 26.9-35.9%] prevalence increased with rising age and calendar age at death. Familial aggregation of endometriosis was strongly suggested by a significantly higher average kinship coefficient among affecteds compared with unaffecteds (P < 0.001) and a higher recurrence risk for full sibs (0.75 95% CI 0.45-1.0) compared with maternal half sibs (0.26 95% CI 0.10-0.41) and paternal half sibs (0.18 95% CI 0.02-0.34). The segregation ratio among affected mothers (44.2%) was not significantly higher compared with unaffected mothers (36.6%). The results support familial aggregation of endometriosis in the rhesus macaque, and indicate that this is a promising animal model for the investigation of mode of inheritance, the location of potential genetic susceptibility loci and the influence of environmental factors.
