Mar 15, The incidence of Rh incompatibility in the Rh-negative mother who is also ABO incompatible is reduced dramatically to % and is believed to.

The above could be explained by the sampling method used, which would result in the overrepresentation of females in the sample. Interestingly, those immunogenic variants are widely distributed among indigenous and mestizo people [ 4755 ]. Todos los derechos reservados. Erythrocytes were separated for the determination of blood type. It was found that allele was more frequent in SinaloaJaliscoand Sonorawhile in PueblaEstado de Mexicoand Veracruz it was less frequent Table 3.

The chi-squared test was performed to compare differences between groups and categories. Interestingly, slight differences were observed in some blood types in both genders.

It is important to take into account the fact that Mexicans are a mestizo population recently established, composed of the admixture of European, African, and majorly Amerindians [ 1920 ] where the allele is incomoatibilidad fixed [ 373946 ]. Blood Groups Distribution by Age and Gender The blood types distribution inpeople studied revealed that O was the most frequent However, their frequencies change across the country Figure 2.

Rh-negative pregnant women can be exposed to the Rh protein that might cause antibody production in other ways too.

For example, in Incompatibllidad, some works have found a positive association between specific HLA haplotypes and acute kidney rejection [ 1517 ]. Indexed in Science Citation Index Expanded. Esta mayor cantidad de anticuerpos puede poner en peligro la vida de un feto en el futuro.

Moreover, the allele frequencies for both loci in previous works were different from those reported here. This stabilizes the level of incompatibilidsd blood cells and minimizes damage from Rh antibodies already in the baby’s bloodstream. The frequencies observed in Coahuila, Nuevo Leon, Jalisco, and Ciudad de Mexico were similar to that previously reported [ 30 — 34 ]; however, for Durango, Puebla, and Guanajuato, proportions of blood antigens were different compared with our results [ 29313435 ].


If this happens, the mother’s body recognizes the Rh protein as a foreign substance. Cuando una mujer tiene un factor Rh negativo y el feto es Rh positivo, esto se llama incompatibilidad del factor U.

Different distributions of blood groups across regions were found; additionally, genetic incompatibilodad revealed that the and allele showed an increasing trend from the north to the center, while the and allele tended to increase from the center to the north. With early detection and treatment of Rh incompatibility, you can focus on more important things — like welcoming a new, healthy baby.

The incompatibilida group includes the states of Coahuila, Queretaro, and Veracruz which have moderate frequencies of the and alleles first quadrant. Material and Methods 2. Her Rh factor may play a role in her baby’s health, so it’s important to know this information early in pregnancy.

The pooled ABO and Rh incompatibilidsd had the following distribution: The fourth group has higher frequencies of and alleles and includes the states of Sinaloa, Sonora, Baja California, Michoacan, Jalisco, and Nayarit which belong to northwest and west of Mexico Table 3.

The highest genetic differentiation for the ABO locus was found in the north and in the west for the D locus. One of the first tests a pregnant woman should expect is a blood-type test. Rg states of Aguascalientes, Guanajuato, and Nuevo Leon, also, were included in this group, since they have higher frequencies of the allele and are more related to Durango than the other states incompatibilirad this group Figure 4.

The blood types distribution incompatbilidadpeople studied revealed that O was the most frequent Differentiation in Mexican populations was found among regions analyzed; also a higher heterozygosity and gene diversity were observed in the north and west; meanwhile, in the east and south-center we found low heterozygosity and gene diversity.



This information will allow health institutions to obtain enough blood units since the site where it is more frequent to get a specific blood type with the confidence that these frequencies will be relatively constant is known, and it will be not necessary to investigate the distribution of blood groups incompaatibilidad these populations again as soon.

Furthermore, blood antigens play an important role in the success of transfusions and organ transplants [ 12 ]; compatibility of ABO groups between donors and recipients is desirable to avoid immune responses against inccompatibilidad and reducing the use of immunosuppressive incompatobilidad.

The second comprises Durango, Aguascalientes, Nuevo Leon, and Guanajuato which have higher proportions of the I B and I D alleles and moderate frequencies of allele second quadrant.

Gas necesario para poder vivir. If a pregnant woman has the potential to develop Rh incompatibility, doctors give her a series of two Rh immune-globulin shots during her first pregnancy.

Rh Incompatibility During Pregnancy

Surprisingly, a negative value for the genetic differentiation parameter in the east was found, suggesting no differentiation in both loci in this region, which is consistent with low heterozygosities observed Table 4. Not everyone carries this protein, though most do. View at Google Scholar P. Thanks to the success rate of Rh immune-globulin shots, exchange transfusions in Rh-incompatible pregnancies are rarely needed in the United States. Together these works show the effects of gene diversity on diagnostic tools and the risk to get some diseases that will have to be taken into account in the future to improve accuracy in biomedicine.

Rh Incompatibility During Pregnancy (for Parents)

The overall gene diversity incompatlbilidad higher at the ABO locus than the D locus ; similarly, the gene diversity within populations was higher in the ABO locus than the D locus. Hillyer, American Association of Blood Banks: View at Google Scholar S. In contrast, B Rh d 0.
