Agglutinins

07/01/2007 - "It was observed that the plasmid-cured strains were immunogenic since infection with live plasmid-cured AO1 isolates generated effective T cell responses and led to increase in serum antibacterial agglutinin titres in C. "
11/01/1998 - "263 sera (18.8%) gave positive results and 41 (2.9%) had a titre of agglutinins > or = 400, suggesting recent infection. "
01/01/1980 - "Antibody response was minimal when sheep cells had been injected 10 days after infection with Toxoplasma; subsequently immunologic reactivity improved, but even after 30 days anti-sheep agglutinin titers were still below pre-infection levels."
01/01/2004 - "The cut-off value for infection was an agglutinin O titre > or = 1/160 (a value validated in an earlier study in the same region). "
07/01/1995 - "The investigations were initiated to study the presence of agglutinins in serum, in response to a previous infection with Bordetella species. "

01/01/2009 - "Difficulties in blood grouping tests and the presence of a warm reactive agglutinin in samples from two patients with hemolytic anemia led to further serologic studies and the identification of anti-IT. "
11/09/2023 - "Cold agglutinin-induced acrocyanosis without hemolytic anemia."
07/26/2021 - "Bloodwork demonstrated severe cold agglutinin mediated haemolytic anaemia. "
07/01/2020 - "Labs revealed the presence of cold agglutinin hemolytic anemia. "
01/01/2020 - "He had a severe hemolytic anemia with a high cold agglutinin (CA) titer. "

02/01/2009 - "Her laboratory test results improved, and she was discharged undelivered with a presumptive diagnosis of cold agglutinin autoimmune hemolytic anemia. "
07/01/2023 - "Cold agglutinin syndrome (CAS) is a rare subset of autoimmune hemolytic anemia (AIHA) and can be classified as either primary or secondary. "
05/23/2022 - "Warm autoimmune haemolytic anaemia mediated by warm agglutinins is a rare and heterogeneous disease which can be idiopathic or secondary to an underlying disease. "
01/01/2022 - "The cold agglutinin titer was examined in 22 patients due to symptoms suggestive of cold agglutinin disease, and all tested negative. "
08/01/2021 - "Resolution of serologic problems due to cold agglutinin mediated autoimmune hemolytic anemia and its transfusion decision."

11/01/2011 - "When the numbers of pertussis cases with high antibody titres in the two tests were compared, 60% of cases with a Yamaguchi agglutinin titre of ≥1:1280 showed an anti-PT antibody titre of ≥100 EU/mL. These results indicate that the bacterial agglutination test is a method with low sensitivity and specificity for the diagnosis of B. "
03/01/2010 - "Therefore, the bacterial agglutination assay against strain Yamaguchi may be a useful tool for diagnosis of adolescent and adult pertussis, especially in young adults, when an agglutinin titer cutoff value of >or=160x is used in combination with clinical symptoms and other clinical laboratory tests."
03/01/2010 - "Analysis of Bordetella pertussis agglutinin titers during an outbreak of pertussis at a university in Japan."
12/01/1997 - "After the third injection, all the infants had a PRP antibody titer greater than or equal to 0.15 microgram/mL and 94.4% of infants had a PRP antibody titer greater than or equal to 1 microgram/mL; the pertussis agglutinin titers were over the threshold 40 and 80 in all infants and 98.1% were over the threshold 320. "
05/01/1994 - "A similar trend was found for pertussis agglutinin titers (93.4 vs. 65.4, P = 0.054). "

07/01/2023 - "Cold agglutinin syndrome secondary to splenic marginal zone lymphoma: a case report."
01/01/2023 - "In primary CAD, lymphoproliferative bone marrow disorder is noted, while as one of the secondary cold agglutinin syndromes (CAS), the initial manifestation of CAD is followed by development of lymphoma. "
03/01/2014 - "The absence of plasmacytoid cells, the presence of plasma cells predominantly outside the nodular lymphoid infiltrates, IGHV4-34 restriction and absence of MYD88 L265P mutation strongly suggest that cold agglutinin-associated lymphoproliferative disease is a distinct entity that is different from lymphoplasmacytic lymphoma. "
01/01/1993 - "It is strongly suggested that lymphoma cells were related to the production of cold agglutinin and the cause of SM."
07/01/1986 - "The cold agglutinin was the initial manifestation of disease and was apparent for at least two months before the diagnosis of lymphoma. "
