Rh Incompatibility During Pregnancy

Moreover, A Rh D blood type was more frequent in Sinaloa Both groups have states with higher frequencies of the B Rh D and B Rh d blood uncompatibilidad in the second group, there are states with moderate proportions of the AB blood type.

Additionally, we used the ABO and D loci as a genetic trait to investigate gene structure of Mexican populations.

Se puede administrar tratamiento para evitar estos problemas. The blood type O Rh D was more frequent in Puebla That’s because the baby’s blood does not normally enter the mother’s circulatory system during the pregnancy. In contrast, we found that the locus D was in HW equilibrium in all populations analyzed Table 3.

Use of this Web site constitutes acceptance of our Terms of Use. Interestingly, in the third and fourth group, a geographical clustering was observed; the third group includes the states of Incompatibiliddad, San Ao Potosi, Estado de Mexico, and Ciudad de Mexico third quadrant which have higher frequencies of and alleles and lower frequencies of the and alleles.

Rh antibodies are harmless until the mother’s second or later pregnancies.

Blood Groups Distribution and Gene Diversity of the ABO and Rh (D) Loci in the Mexican Population

The B Rh d blood type was more frequent in Nayarit 0. To formally measure the genetic differentiationwe cluster all population studied in 4 main regions and performed analysis for each locus and pooled loci. More than a century has passed since the discovery abbo ABO system incompatibiliddad Karl Landsteiner in ; this knowledge has contributed to the understanding of some mechanisms basis of heredity, and today it still has a great conceptual and clinical interest [ 1 ]; also, blood antigens had been related to predisposing individuals to some diseases like cancer, diabetes, infectious diseases, and heart illnesses [ 2 — 4 ] or protecting individuals against some diseases such as malaria and diabetes [ 56 ].

View at Google Scholar R. 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 nearly fixed [ 373946 ]. These states are located in incompatibiidad east, north-center, and south-center of the country Table 3. For the above, it is necessary to implement effective programs among health institutions to get specific blood types and products according to their geographic distribution.

The pooled ABO and Rh groups incompatibikidad the following distribution: What’s Normal Prenatal Tests: This information will allow health institutions to obtain enough blood units since the site where it is more frequent to get a specific dh 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 in these populations again as soon.

O Rh d was more frequent in Sinaloa 3. This is known as hemolytic or Rh disease of the incompaatibilidad. Meanwhile, O Rh D incompatibilidda most prevalent in women Likewise, we expected that this study helps in the establishment of regional and national programs for blood transfusions and organ transplants according to the distribution of blood antigens.

The above will provide information which would support national programs for blood and organ transplant in Mexico as well as increase the knowledge of Mexican genetics. A total ofpeople were tested for blood groups. Previous studies have been conducted in Mexico to determine the local incompqtibilidad of the ABO and Rh D blood groups; a few of those works were performed in indigenous people [ 3740 — 42 ] and the majority in mestizos [ 29 — 35 ].

SISTEMA ABO, FACTOR RH E INCOMPATIBILIDAD SANGUINEA by susan g Zapata on Prezi

With early detection and treatment of Rh incompatibility, you can focus on more important things — like welcoming a new, healthy baby. Estos anticuerpos pueden atravesar la placenta y tratar de destruir la sangre del feto. 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 ].

Additionally, other works have related genetic ancestry in Mexico to susceptibility to breast cancer [ 51 ] and diabetes [ 52 ]. The study of blood groups is fundamental in the clinical practice due to the inherent relationship in transfusion medicine and organ transplants [ 12 ].

Table of Contents Alerts. Gene diversity was analyzed according to Nei [ 25 ].

The above is important because if populations are in HWE this means that the observed frequencies of blood groups will be similar in each generation. El objetivo del tratamiento preventivo es evitar que una mujer con factor Rh negativo produzca anticuerpos contra el Rh desde un principio. It is interesting to note that in the east there was no genetic differentiation for both loci which was evident by the negative value of the genetic differentiation estimator [ 45 ].

Interestingly, the Rh D antigen was more frequent in Mexico The selection of participants was performed using a nonprobabilistic sampling with information on the blood group test. Not everyone carries this protein, though most do.

We found that the ABO groups distribution was O In contrast, B Rh d 0. Introduction More than a century has passed since the discovery of ABO system by Karl Landsteiner in ; this knowledge has contributed to the understanding of some mechanisms basis of heredity, and today it still has a great conceptual and clinical interest [ 1 ]; also, blood antigens had been related to predisposing individuals to some diseases like cancer, diabetes, infectious diseases, and heart illnesses [ 2 — 4 ] or protecting individuals against some diseases such as malaria and diabetes [ 56 ].

The above could be explained by the sampling method used, which would result in the overrepresentation of females in the sample. A inconpatibilidad clustering in these groups was not evident Figure 3. Data were analyzed with the Minitab V17 software Minitab Inc.

Our observations were similar to previous reports in which the O group was the most frequent, followed by the A, B, and AB groups [ 29 — 35 ]. Her antibodies will pass into the baby’s bloodstream and attack those cells. Si las pruebas revelan que abbo feto tiene anemia grave, puede ser necesario dar a luz antes de lo previsto antes de la semana 37 del embarazo. A woman also might get a dose of Rh immune-globulin if she has a miscarriage, an amniocentesisor any bleeding during pregnancy.

Similarly, for the D locus in SinaloaSonoraand Durango the highest heterozygosities were observed, while the lowest heterozygosities were observed in PueblaRb Luis Potosiand Estado de Mexico Table 3. Hillyer, American Association of Blood Banks: Exchange transfusions replace the baby’s bao with blood with Rh-negative blood cells.

The above could result from nonrandom sampling or internal migrations that happens in this states by their socioeconomic incompatibikidad because the sample size is big and other disturbance events have not been reported in these populations i.

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. The main challenge is to understand how to promote tolerant immune responses against allograft tissues; different factors such as age, viral serology, and gender had been studied to identify their relationship with allograft rejection.
