Abstract
Aims: In kidney transplant recipients (KTR), antibody (Ab) synthesis is hampered by AZA and CsA. We here report in a prospective cohort study, the effects of mycophenolate mofetil (MMF) associated to a calcineurin inhibitor on plasma levels of anti-tetanus anatoxin Ab (TAnAb) and anti-pneumococcal Ab (PnPsAb). Methods: Serum titers of the TAnAb and the PnPsAb against serotypes 14, 19F and 23F were measured in 94 KTR on Day 0 (TO) and 1 year (T12) after renal transplantation and in 49 healthy controls. Results: 1) At TO, TAnAb were detected in only 71% of patients vs. 98% of controls (p < 0.0001) and the titers were significantly lower in KTR (1.46 UI/ml vs. 2.74 in controls, p = 0.01); they further decreased between TO and T12 (1.46 UI/ml to 0.31, p < 0.0001). The calculated half-life (t(1/2)) of TAnAb was 7.7 months, as compared to more than 10 years in a normal population. 2) In KTR, PnPsAb titers decreased significantly between TO and T12 (p < 0.005); the t(1/2) of the different PnPsAb ranged from 9.2 to 11.9 months. Conclusions: In KTR treated by MMF and CNI, the TAnAbs and PnPsAbs titers decrease significantly and profoundly during the first year. Immunization pre-transplantation should be encouraged to maintain adequate post-transplant Abs levels.
