[Prevention of infections in chronic bronchitis using vaccination and/or immunomodulation].
Polyvalent antimicrobial vaccines have been widely used in chronic bronchitis for nearly fifty years without their effect or mechanism of action always being well understood. The polysaccharide vaccines, in particular pneumococcal, are better defined chemically and in their mode of action. However, it does not seem that ordinary chronic bronchitis is a good indication for these vaccines. The immunomodulators, extracts of the cell wall of certain bacteria, are aimed at increasing the host's defence capacity in a non-specific manner. The addition of ribosomes may favour specific and non-specific immunomodulation. Certain vaccines have shown their efficacy in reduction of infective episodes in chronic bronchitis. However, other studies ought to be undertaken to obtain purified products which are not toxic and are yet more effective. Finally, it is necessary to have better knowledge of the mode of administration and of the doses administered corresponding to the optimal efficacy of the vaccines.
