[Irregular antierythocytic antibodies outside of the ABO system in the perinatal period]. / Anticuerpos irregulares antieritrocitarios fuera del sistema ABO en el periodo perínatal.

Included in this study are the results of the tests done with irregular anti-erythrocytic antibodies outside of the ABO system of women in reproductive stage. In 2,623 cases considered, 279 samples positive for the antibodies were found (10.6%). In 184 cases (65.9%), the antibodies were classified as "immune irregular". The most frequently found antibodies from this group were the anti-D (63.08%), followed by the anti-c (1.07%), the anti-Kell (0.72%), anti-C, anti-E and an anti-Rh system (0.36% for each one). In 52 cases (18.6%) there were irregular "natural" antibodies, predominantly the anti-Lewis (9.68%), followed by anti-P (5.02%), the anti-I (3.2%), an anti-M and an anti-N (0.36% each one). In 43 (15.4%) cases, we were not able to identify the specificity of the antibody found. We include a discussion and a comparison of the frequency of these antibodies in our population. Based on these data, we recommend the clinician to consider the existence and specificity of the irregular anti-erythrocytic antibodies in their obstetric patients, candidates to transfusional therapy, as well as those newborn with hemolytic diseases.

[Antierythrocyte antibodies due to ovarian dysgerminoma. A case report]. / Anticuerpos antieritrocitarios por disgerminoma del ovario. Informe de un caso.

The case of a 24-year-old woman with fever, abdominal pain and weight loss, is presented. Right ovarian dysgerminoma was diagnosed; group A blood, negative direct Coombs. The search for free serum antibodies was positive, with specificity: auto anti 1, anti P with activity at 37 degrees C. Hysterectomy, appendectomy, omentectomy and retroperitoneal ganglia biopsy, were performed; the latter one showed metastasis. Blood transfusions were given. Thirty days postoperative, the red cell polyagglutination had disappeared, as well as antibodies.
