Immune-complex vasculitis, allergic

Cell therapy consists of the parenteral or enteral administration of cells or parts of cell obtained from animal organs and/or tissues from cattle, sheep, pigs, or rabbits. Two different types of cell preparations are in use fresh cells, which are administered in fresh form, and dried cells or so-called sicca cells, which are prepared for later use. The most prevailing risks of cell therapy are local and generalized allergic reactions (fever, nausea, vomiting, urticaria, and anaphylactic shock). Other untoward consequences include fatal and non-fatal encephalomyelitis, polyneuritis, Landry-Guillain-Barre sjmdrome, fatal serum sickness, perivenous leukoencephalitis, and immune-complex vasculitis.
