Publications in this field reveal conflicting data and opinions; no evidence-based guidelines currently exist. However, in spite of several discrepancies some commonly accepted information and conclusions exist. Efforts to find a common strategy of re-immunization should be directed towards setting up prospective studies on sufficient numbers of patients to obtain statistically relevant end points.
