Query: Regularity results for local solutions to some anisotropic elliptic
  equations   In this paper we study a class of anisotropic equations with a lower order
term whose coefficients lay in Marcinkiewicz spaces. We prove some regularity
results for local solutions requiring any control on the norm of the
coefficients.
