A generalisation of the Stieltjes relations for the Painleve-IV transcendents and their higher analogues determined by the dressing chains is proposed. It is proven that if a rational function from a certain class satisfies these relations it must be a solution of some higher Painleve-IV equation. The approach is based on the interpretation of the Stieltjes relations as local trivial monodromy conditions for certain Schrodinger equations in the complex domain. As a corollary a new class of the Schrodinger operators with trivial monodromy is constructed in terms of the Painleve-IV transcendents.
