Thirty male patients with sexually acquired reactive arthritis (SARA) have been studied at the time of their initial presentation and thereafter. Chlamydia trachomatis was isolated from the urethral exudate of 9 (36.0%) of the 25 patients from whom urethral specimens were taken, and elevated titres of IgM antibody of C. trachomatis were detected in 11 (36.6%) of the 30 initial sera. Thirteen (4...

Objective To determine seroprotection and vaccine response rates produced by a diphtheria–tetanus–acellular pertussis–inactivated poliovirus–Haemophilus influenzae type-b conjugate (DTaP–IPV//PRP~T) vaccine containing a polyribosyl-ribitol-phosphate (PRP)– tetanus toxoid conjugate (PentaximTM) and given with a hepatitis B vaccine. Methods In this multicentre open-label trial, 424 infants who re...

autoimmune thrombocytopenic purpura, autoimmune haemolytic anaemia, systemic lupus erythematosus and rheumatoid arthritis. [2–4] The production of antibody depends on the antigenically driven clonal expansion of B cells into antibody-producing effector plasma cells. Plasma cells are short-lived cells, and survival of the populations depends on differentiation from their progenitor B cells [5]. ...

Background and Aims: A subgroup of group O individuals called ‘dangerous universal donors’ have immune (IgG) anti A and anti B antibodies which are active at 37˚C and capable of reacting with the red cells and causing lysis. The aim of this study was to find the prevalence of dangerous O group among the voluntary donor population and to assess the relation between the degree of haemolysis and t...

COVID‐19 is caused by SARS‐CoV‐2 and spreads from person‐to‐person. Pregnant women continued to be vulnerable COVID‐19. Infant protection covid-19 infection primarily dependent on neonatal innate immune responses maternally derived, transplacentally acquired antibodies. Our aim was study trans placental passage of anti-SARS-CoV-2 antibody the magnitude natural passive immunity in infants born m...

Elimination of lymphatic filariasis (LF) in the Pacific Island Countries and Territories (PICT) has been defined as <0.1% circulating filarial antigen (CFA) prevalence in children born after the implementation of successful mass drug administrations (MDAs). This research assessed the feasibility of CFA and antibody testing in three countries; Tonga, Vanuatu, and Samoa. Transmission is interrupt...

Introduction: The antibody titre offered by the Royal College of Pathologists Australasia Quality Assurance Programs (RCPAQAP) surveys laboratory technical procedures on titres using various methods. A review is performed reports last 5 years to ascertain any differences in sensitivity between methods employed laboratories. Method: Titre results were extrapolated from 20 samples over years. are...
