Drug-induced immune hemolytic anemia (DIIHA) is a rare side effect of drugs. DIIHA may cause a systemic inflammatory response that results in acute multi-organ failure and death. Ceftizoxime belongs to the class of third generation cephalosporins, which are the most common drugs associated with DIIHA. Herein, we present a case of a 66-year-old man who developed fatal DIIHA after receiving a second dose of ceftizoxime. He was admitted to receive photodynamic therapy. He had a history of a single parenteral dose of ceftizoxime 3 months prior to admission. On the day of the procedure — shortly after the infusion of ceftizoxime — the patient's mental status was altered. The blood test results revealed hemolysis. Oliguric acute kidney injury developed, and continuous renal replacement therapy had to be applied. On the suspicion of DIIHA, the patient underwent plasmapheresis. Diagnosis was confirmed by a detection of drug-dependent antibody with immune complex formation. Although his hemolysis improved, his liver failure did not improve. He was eventually discharged to palliative care, and subsequently died.

We report here the results of the external quality assessment scheme (EQA) of blood bank tests in Korea carried out in 2015. The proficiency testing specimens used in the survey were prepared at Ajou University Hospital. The response rates from participating laboratories for the first and second trials were 98.7% (542/549) and 98.2% (544/554), respectively. No answers to tests were considered incorrect, and the average accuracy rates for six different test items on the standard survey were as follows: ABO grouping, 99.4% to 100.0%; RhD typing, 99.4% to 100.0%; crossmatching, 93.6% to 99.0%; direct antiglobulin test (DAT) using a polyspecific reagent, 92.9% to 98.3%; DAT using an IgG monospecific reagent, 94.6% to 100.0%; DAT using a C3d monospecific reagent, 84.2% to 98.6%; unexpected antibody screening test, 94.5% to 100.0%; and antibody identification test, 93.8% to 100.0%. We performed a pilot survey on reactivities to A1 (54 responses) and H (50 responses); Rh C, c, E, and e antigen testing (47 responses); and ABO antibody titration (10-34 responses). We obtained excellent results for this EQA, and these results will be helpful for improving or maintaining the quality of the participating laboratories.

BACKGROUND: Detection of anti-Kidd antibody is important because of its clinical significance. If detection is difficult due to weak serological reactivity or dosage effect, use of an enzyme method could be helpful. However, despite use of an enzyme method, we still observed weak reactivity of anti-Kidd antibody. METHODS: All identified anti-Kidd antibody cases from Jan 2012 to Aug 2015 in Asan Medical Center were reviewed. Antibody identification test was performed using the column agglutination technique using Bio-Rad ID-DiaPanel with LISS/Coombs card, Bio-Rad ID-DiaPanel-P with NaCl/Enzyme card, and ID-DiaPanel-P with LISS/Coombs card. The test results were compared. RESULTS: Sixty cases of anti-JK(a) or anti-Jk(b) were detected and tested by enzyme method. Among them, 34 (56.6%) cases showed strengthened reactivity using the ID-DiaPanel-P with NaCl/Enzyme card method. However, 26 (43.4%) cases showed weakened reactivity. Of these, 13 cases that could be tested by an additional method using ID-DiaPanel-P with LISS/Coombs card containing anti-IgG and anti-C3d showed successfully strengthened reactivity. CONCLUSION: The reactivity of anti-Kidd antibodies that was not strengthened using ID-DiaPanel-P with NaCl/Enzyme card method could be successfully strengthened by use of the ID-DiaPanel-P with LISS/Coombs card.

All living creatures on this planet, from bacteria to human, produce sugar chains (glycans). This means that sugar chains are essential for living a life. Abundant, diverse, and highly regulated repertoire of glycans are synthesized by glycosylation process in cells. Located in proteins (N-glycans and O-glycans) and lipids (glycosphingolipids), glycans participate in many vital biological processes including molecular recognition, cell adhesion, molecular trafficking and clearance, receptor activation, and signal transduction. Histo-blood group antigens that are composed of sugar chains are expressed under the control of the Secretor, Lewis and ABO glycosyltransferases. They play important roles in microbial infections and cancers. Many of sugar chains associated with histo-blood group antigens are exploited as receptors for microorganisms. Aberrant glycosylation of proteins and lipids occurs commonly during malignant transformation and leads to the expression of tumor-associated glycans. In this review, over the scope of transfusion medicine, we discussed deep down the biologic meaning of sugar chains, through exploring how the sugar chains are synthesized, structured, and functioning.

BACKGROUND: The therapeutic efficacy of red blood cell (RBC) transfusions in patients with autoimmune hemolytic anemia (AIHA) is highly debated because of speculations on the increased risk of transfusion reactions; yet it is a suggested adjuvant therapy in anemic patients with life-threatening hypoxemia. In this study, we evaluated the safety and efficacy of RBC transfusions in AIHA patients. METHODS: Daily changes in hemoglobin, total bilirubin, and lactate dehydrogenase (LDH) were assessed in 161 AIHA patients without bleeding history who were transfused once with 1-5 units of the least-incompatible RBCs and monitored over a seven-day period. Post-transfusion patients positive for alloantibodies only or those without RBC-specific antibodies were considered as control groups (N=100 for both groups). RESULTS: The three groups revealed similar increases in hemoglobin of 1.40-1.70 g/dL (autoantibodies), 1.20-1.60 g/dL (alloantibodies only), and 1.40-1.55 g/dL (no antibodies) for seven days following transfusion of 10 mL RBCs/kg. During follow-up, no significant changes in total bilirubin or LDH levels were detected in the AIHA group compared with controls. Influences due to autoantibody type, direct antiglobulin test (DAT) specificity and strength, and steroid therapy status on transfusion reactions were not evident in AIHA patients. In addition, changes in hemoglobin levels were significantly higher (P<0.001) in severe anemia (<5 g/dL) than in other patients. CONCLUSIONS: Transfusion of the least-incompatible RBCs in AIHA patients is effective and safe without any associated increase in hemolysis risk when compared with post-transfusion patients positive for alloantibodies or those lacking RBC-specific antibodies.

We report here the results of surveys on external quality assessment (EQA) of blood bank tests in Korea carried out in 2014. The proficiency testing specimens were prepared at Ajou University Hospital and the response rates for the 1st and 2nd trials were 94.3% (537/549) and 96.0% (545/554), respectively. No answers were considered incorrect, and the average accuracy rates of six different test items on the regular survey were as follows: ABO grouping, 98.5% to 100.0%; RhD typing, 98.1% to 99.4%; crossmatching, 91.2% to 99.6%; direct antiglobulin test (DAT) using a polyspecific reagent, 96.7% to 98.4%; DAT using an immunoglobulin-G monospecific reagent, 93.8% to 98.7%; DAT using a C3d monospecific reagent, 89.5% to 98.7%; unexpected antibody screening test, 96.2% to 100.0%; and antibody identification test, 69.8% to 100.0%. Test items for the pilot survey were reactivities to anti-A1 and anti-H, Rh subgrouping, and ABO antibody titration. Except for the result of the antibody identification test for specimens with multiple antibodies, we obtained excellent survey results for the EQA of blood bank tests carried out in 2014. In addition, the number of participating institutes was higher in 2014 than in 2013. The EQA of blood bank tests in 2014 should be helpful for improving the quality of the participating laboratories.

Anti-f(ce) has been associated with hemolytic transfusion reaction (HTR) and hemolytic disease of the fetus and newborn (HDFN), however, anti-Cs(a) has not been associated with red blood cell (RBC) destruction. Although anti-Cs(a) has clinical insignificance as a high-titer low-avidity (HTLA) antibody, this antibody can cause confusion in interpreting an antibody identification test, particularly coexistence of a clinically significant antibody. A 65-year-old woman with liver metastases of Klatskin tumors and cholangitis was admitted to the hospital for abdominal pain. She developed hematochezia on hospital day 10. She was at the status of active bleeding and required transfusion. The result of antibody identification test was warm-reactive autoantibody and unidentifiable alloantibody, therefore, the least incompatible packed RBCs had to be transfused to the patient. No hemolytic transfusion reaction occurred and hemoglobin level was normalized. Thereafter, anti-f(ce) and anti-Cs(a) antibodies were identified in the patient's serum. To the best of our knowledge, this is the first report of anti-f and anti-Cs(a) antibodies in Korea.

Intravenous immune globulin (IVIG) is widely used in treatment of hypogammablobulinemia and for immunomodulation. Passive transfer of anti-D activity through administration of IVIG may cause difficulty in serologic assessment of patients. Here we report on a case of passive anti-D from IVIG in a D positive patient. The patient was a 72-year-old Korean woman who was hospitalized for refractory immune thrombocytopenic purpura that is not cured after steroid therapy. IVIG 6,000 mg was administered for treatment of immune thrombocytopenic purpura. After IVIG administration for two days, we identified anti-D in the patient and a positive direct antiglobulin test was demonstrated. The patient's hemoglobin level remained unchanged. After IVIG administration for 10 days, the patient's specimen was negative for anti-D, as would be expected with passively acquired antibody. Antibodies in IVIG may confuse and complicate serologic testing of transfusion candidates. Therefore, passive transfer of anti-D should be considered when anti-D is detected, especially when the patient has received IVIG, as in this case.
