              Abstract
              We prove a refinement of Campanatos result on local and global under Dirichlet boundary conditions BMO regularity for the gradient of solutions of linear elliptic systems of second order in divergence form we just need that the coefficients are «small multipliers of BMOΩ» a class neither containing nor contained inC0 left bar Omega  right We also prove local and global Lp regularity this result neither implies nor follows by the classical one by Agmon Douglis and Nirenberg
