Immune hemolytic anemia associated with probenecid.

Upon hospital admission a patient was found to have severe anemia and a strongly positive direct antiglobulin test (DAT). The patient was taking probenecid periodically for gout. An antibody was detected in the patient's serum that only reacted with red blood cells (RBCs) when probenecid was added. Eluates from the patient's RBCs, with and without the presence of drug, were nonreactive. Upon the discontinuation of probenecid, the patient's hemoglobin level improved steadily. We believe this to be the first reported case of immune hemolytic anemia associated with probenecid.

Difficulty in LW typing as revealed by a family study.

A family is described in which two members of the second generation are of the phenotype LW3. In the course of the investigation the mother of the LW3 propositus was at first believed to be phenotypically LW3 as well. Eventually, it was shown that she is, in fact, phenotypically LW2 but that her R-1 (no D), LWlw, genotype had resulted in less LW being present on her red blood cells than is expected in LW2 persons. This reduced level of LW could not be detected with one example of anti-LW made by an LW3 individual.

Donor antibody detection using plasma in place of serum.

Twenty-two types of erythrocyte antibodies from 53 individuals were studied for their detectability in serum versus CPD, ACD and EDTA plasms samples. In no specimen thus far tested was there an antibody detectable in serum but not detectable in plasma. These results suggest that blood samples collected in anticoagulant are suitable not only for antigen typing but also for antibody screening.

Acute hemolytic anemia associated with a chlorpropamide-induced apparent auto-anti-Jka.

A patient with acute hemolytic anemia and a positive direct antiglobulin test was found to be Jk(a + b +) with anti-Jka in her serum. For 2 weeks prior to admission, the patient had taken chlorpropamide, a hypoglycemic agent. The drug was discontinued upon the diagnosis of hemolytic anemia, and the hemoglobin concentration gradually increased. When chlorpropamide was added to the patient's serum in vitro, it enhanced the reactivity of the anti-Jka, and 40 days posttransfusion, the serum would only react with Jk(a+) red cells when chlorpropamide was present. These findings suggest that a chlorpropamide-dependent antibody with Jka specificity had formed. We do not know why the antibody induced by chlorpropamide reacted preferentially with Jk(a+) red cells.
