More What is Tetanus Toxoid tetanus toxoid vaccine? Tetanus is a serious disease caused by bacteria. Tetanus lockjaw causes painful tightening of the muscles, usually all over the body.
Introduction Treatment with abatacept has demonstrated efficacy in patients with active rheumatoid arthritis RA and an inadequate response to methotrexate, and in those with an inadequate response to anti-TNF therapy [ 1 — 3 ]. Abatacept is a soluble fusion protein consisting of the extracellular domain of human cytotoxic T-lymphocyte-associated antigen-4 linked to the Fc hinge, CH2 and CH3 domains portion of human IgG1, which has been modified to be noncomplement fixing.
CD28 co-stimulatory signal required for full T-cell activation [ 4 ]. Activation of T cells usually requires two signals from antigen-presenting cells [ 56 ]. The first signal is mediated through the T-cell receptor via an interaction with major histocompatibility complex-presented peptide antigen [ 6 ].
The impact of abatacept on humoral responses to two T-cell-dependent neoantigens, bacteriophage X and keyhole limpet hemocyanin, was previously evaluated in psoriasis patients treated with abatacept [ 8 ].
While the responses to these neoantigens were reduced, the primary response to these T-cell-dependent antigens was not completely blocked. In addition, tertiary and quaternary responses were restored following discontinuation of abatacept administration, demonstrating that tolerance to these neoantigens was not induced [ Drug study mucosulvan verorab tetanus toxoid ].
In the present article we describe the effect of a single dose of abatacept on the humoral response in healthy subjects to two vaccines, tetanus toxoid vaccine and valent pneumococcal vaccine.
This study was carried out in normal healthy subjects in order to evaluate the effects of abatacept on the response to therapeutic vaccines in intact immune systems before evaluating the response in RA patients.
Patients with active RA may not have normal immune function parameters, and often receive background disease-modifying antirheumatic drugs, many of which are immunosuppressive. It was intended that data from this study would guide the design of other studies evaluating vaccine responses in patients with RA.
These critical studies in 'real-world' RA patients are ongoing. In addition, the effect of abatacept upon two different types of antigen response was evaluated. The tetanus toxoid vaccine comprises a peptide antigen, and, since most individuals in the United States have been vaccinated with tetanus toxoid, the response measured in this study can be considered a T-cell-dependent memory response.
Polysaccharides, however, are able to elicit responses in the absence of T-cell help, although the magnitude of the response is reduced under those circumstances [ 9 — 11 ].
The response to pneumococcal vaccine measured in the present study is therefore not entirely T-cell independent, or the response is less T-cell dependent.
Finally, as a normal humoral response to T-cell-dependent antigens peaks at around 2 weeks [ 12 ], we also analyzed the impact on humoral response of the timing of vaccination relative to abatacept administration. Materials and methods Study design This open-label, parallel-group, controlled study was conducted at three study centers in the United States.
Subjects were randomized to one of four treatment groups Figure 1.
Figure 1 Patient disposition from enrollment to completion of the trial. Group A control group subjects received separate 0.
Group B subjects vaccines 2 weeks before abatacept received separate 0.
Serum samples were collected prior to the abatacept infusion on study day 14 and 14 days later on study day Group C subjects vaccines 2 weeks after abatacept received a single i.
Serum samples were obtained on study day 14 prior to vaccinations and at 14 and 28 days after the vaccinations study days 28 and 42, respectively. Group D subjects vaccines 8 weeks after abatacept received a single i.
Serum samples were obtained for subjects of Groups A and B at study days 14 and 28, for Group C subjects at study days 28 and 42, and for Group D subjects at study days 70 and Subjects were excluded if they had received any live vaccine within the prior 4 weeks, had received a tetanus booster or pneumococcal vaccine within 5 years or if they had baseline anti-tetanus antibodies below clinically detectable levels.
Abatacept serum concentrations were measured at the same time as the antibody titers were determined.Footnotes † Persons who are immunocompromised because of immune deficiency diseases, leukemia, lymphoma, generalized cancer, or the acquired immunodeficiency syndrome, or who are receiving immunosuppressive therapy with corticosteroids, alkylating agents, anti-metabolites, or radiation..
