Vanishing results for reduced Lp,q-cohomology are established in the case of twisted products, which are a~generalization of warped products. Only the case q ≤ p is considered. This is an extension of some results by Gol'dshtein, Kuz'minov and Shvedov about the Lp-cohomology of warped cylinders. One of the main observations is the vanishing of the "middle-dimensional" cohomology for a large class of manifolds. This means that the L2-Betty numbers are zero in the "middle dimension".
