In human immunodeficiency virus (HIV)-infected individuals the amount of antibodies formed after vaccination with T-cell-dependent recall antigens such as tetanus toxoid is proportional to the peripheral blood CD4(+) T-lymphocyte counts. To investigate whether the immunoglobulin G (IgG) subclass distribution and avidity of the antibodies produced after vaccination are affected as well, we gave ...

OBJECTIVE To emphasise that tetanus still occurs in the United Kingdom, particularly in elderly people-as illustrated by two case reports-and to examine the state of tetanus immunity in elderly people. METHODS 111 elderly people (over 65 years) were studied: 43 males, mean age 77.7 years, range 67-94; 68 females, mean age 81.3 years, range 67-95. They were either attending the accident servic...

A rapid quantitative microenzyme-linked immunosorbent assay for the detection of immunoglobulin G antibodies to tetanus toxoid is described. The assay is performed in 2.5 h and detects antibody levels of between 0.1 and 6 U/ml. Quantitation of the antibody concentration is unique in that multiple serum dilutions are tested on a single patient, the results are plotted as an antibody dilution cur...

We conducted a prospective nested case-control study among military service members to investigate whether antibodies against tetanus or diphtheria predict multiple sclerosis (MS) risk. Paired T-tests were used to compare means of anti-tetanus and diphtheria toxoids among 56 MS cases and 112 matched controls. Conditional logistic regression was used to estimate odds ratios (OR). There were no d...

Topical corticosteroids are the mainstay of treatment in inflammatory skin diseases. Corticosteroids penetrate human skin, especially when the penetration barrier is damaged. Whether long-term application of topical corticosteroids can lead to alteration of immune responses is not clear. We sought to examine the impact of topical corticosteroids on immune responses in patients using long-term t...

BACKGROUND Because adolescents and adults act as a primary source of pertussis infection for infants, vaccination of mothers immediately postpartum is a potential strategy to reduce transmission (cocoon strategy). For this to be effective, high levels of antibodies must be achieved rapidly after vaccination. We sought to determine whether the antibody response to tetanus-diphtheria-acellular pe...

Effective immunization programs initiated many years ago have made tetanus a rare disease in the United States today. These programs have been so successful that in 1981 the Sixth International Conference on Tetanus (Lyon, France) proposed a goal of eliminating tetanus from the United States by 1985 and from the rest of the world by the year 2000.1 This goal has yet to be achieved. During the l...

To determine if inactivated poliovirus vaccine combined with diphtheria and tetanus toxoids and whole-cell pertussis vaccine interferes with the immunogenicity of pertussis vaccine, we performed a randomized trial of diphtheria and tetanus toxoids and pertussis vaccine combined with inactivated poliovirus vaccine given as a single injection or as two separate injections at the same visit to inf...

The baculovirus expression vector p36C was used to express in cells of the insect Spodoptera frugiperda fragment C of tetanus toxin under the control of the strong polyhedrin promoter. Fragment C was expressed intracellularly at a high level and was soluble, allowing it to be purified by affinity chromatography with monoclonal antibody TT08. Purified fragment C from baculovirus was used to immu...

To define the capacity of a tetanus toxoid booster to reactivate infant-triggered immunity, anti-tetanus antibodies were assessed before and after boosting 162 adolescents and 219 children from Mfou (Cameroon). Among 63 adolescents with 3 recorded dose of infant DTP, 29/63 (46%) responded with a > or =4-fold increase of antibody titers, 35/63 (55%) reaching the 0.10UI/ml threshold. Response rat...
