The high incidence antigert Jr" was first identified in 1970 by Stroup and Macllroy. Anti-Jr~ was immune antibodies developed by transfusion or pregnancy and occasionally cause hemolytic disease of the newborn and transfusion reaction, but these usually mild. We are reporting the first case of anti-Jra in Korea, which was identified in pregnant woman with transfusion history. The 35 year old pregnant woman(G6P4L1D3A1) admitted to treat for incompetent internal os of cervix on department of Obstetrics and Gynecology. Prenatal irregular antibody screening was negative. One unit of RBC was transfused at 21 gestational weeks for correction of anemia. One week later, irregular antibody was detected in her serum. The antibody reacted best by indirect antiglobulin test and panagglutinated all identified cells. The titer was 1 : 8. The antibody was identified as anti-Jr by Dr. Osaka Red Cross Center. Her phenotype of Jra was Jr(a-), but there was no Jr(a-) person in her family. She might have anti-Jra in her serum with undetectable level due to multiple pregnancies. In this case, the development of anti-Jr was stimulated by one unit of RBC transfusion with anamnestic reaction. The titer of anti-Jr was gradually reduced during pregnant period. She delivered at 37 gestational weeks by cesarian section. The baby was clinically well at birth and typed as Jr(a+).

BACKGROUND: Hypocalcemia is the most common side effect in large-volume leukapheresis (LVL) for collection of peripheral blood stem cells (PBSCs). We evaluated the effect of intravenous calcium infusion on the hypocalcemic symptoms during LVL. METHODS: Seventy-six LVLs with hypocalcemic symptoms were participated in this study. LVLs were performed using Gambro Spectra (blood rate, 80 mL/min; whole blood to ACD-A with heparin, 24:1) until 20 L of blood was processed. Blood flow rate was slowed to 60-70% of initial in 35 LVLs (group A) and 20 mL of 3% CaCl2 was infused intravenously in 41 LVLs (group B). Serum levels of ionized calcium, total magnesium, and electrolytes were determined before and after each LVL and analyzed with students?-test. RESULTS: The observed hypocalcemic symptoms were perioral paresthesias (71%), digital numbness (17%), chest tightness (4%), chills (4%), headache (3%), and vomiting (1%). Serum ionized calcium decreased by 15.9% in group A (P<0.001) and increased by 1.3% in group B. Total magnesium in group A (11.4%, P=0.002) and potassium in both groups (9.5%, P<0.001 and 8.6%, P=0.02, respectively) were significantly reduced. In group A, hypocalcemic symptoms were not completely relieved but weakened in 63%, and blood flow rate had to be kept below 55 mL/min in 37%. In group B, the symptoms were relieved by 20 mL of 3% CaCl2 in 27% and by 40 mL in 73%. CONCLUSION: Reduction of blood flow for relief of hypocalcemia symptoms was only helpful in lightening the symptoms. Intravenous infusion of calcium was more effective and convenient to alleviate hypocalcemic symptoms and did not affect LVL procedures nor serum levels of ionized calcium.

BACKGROUND: Cytoplasmic stainings in antinuclear antibody tests using HEp-2 cells are usually undetermined and the significance has not been fully understood until now. Hence, we evaluated their clinical characteristics and also the coexistence of other autoantibodies in the sera with cytoplasmic stainings in antinuclear antibody tests. METHODS: We reviewed clinical records retrospectively in 53 sera showing cytoplasmic stainings among 3, 610 sera that were tested antinuclear antibodies from January to September, 2002 and performed antimitochondrial antibodies (AMA) tests using indirect immunofluorescence (IIF) and antibodies to antiribosomal P and extractable nuclear antigens (ENA) tests using enzyme immunoassay (EIA). RESULTS: Among 53 sera with cytoplasmic stainings, 31 sera showed an AMA pattern and 15 sera showed an antibody to ribosomal P pattern. Three cytoskeletal and one golgi complex patterns were also observed. The most common diagnosis was autoimmune disorders (32, 60.4%) and hepatic disorders (excluding autoimmune hepatitis) (6, 11.3%). Hepatic disorders including autoimmune, drug-induced, and alcoholic hepatitis were most commonly observed (32.3%) in sera with an AMA pattern. On the other hand, various autoimmune disorders such as SLE, systemic sclerosis, dermatomyositis, and polymyositis were observed (86.7%) in sera with a ribosomal P pattern. Of 31 sera with the AMA pattern, the corresponding antibodies were confirmed in three by IIF and of 15 sera with a ribosomal P pattern, only one was confirmed to have this antibody by EIA. All the confirmed sera showed high titered (>1: 320) cytoplasmic stainings. Antibodies to ENA were positive in sixteen (RnP, 5; Sm, 4; Ro, 5; La, 2) and anti-DNA in three of the sera. CONCLUSIONS: Although cytoplasmic staining patterns are not disease specific, it is suggested that continuous high titer stainings be followed up since they could provide diagnostic help.

The Di(a+b-) phenotype is extremely rare among Caucaclans and mostly confined to mongoloids. The incidences of Di antigen among Koreans were reported to be 6.1 to 14.5%, with an average of 9.6%; it can be calculated that the frequency of Di(a+b-) is 0.25% on the average. Authors report the first case of hemolytic disease of the newborn due to anti-Dib in Korea. The Diego phenotypes of the mother, baby and father were Di(a+b-), Di(a+b+) and Di (a-b+), respectively. The mother's serum and eluate from infant's erythrocytes contained anti-DP antibody active in the antiglobulin phase. After transfusions of Di-negative red cells from the mother and mother's relative, the patient was recovered from anemia and jaundice.
