With optical and near-infrared follow-up observations of gamma-ray bursts (GRBs) it is possible to study the chemical enrichment of galaxies at high redshift. Especially interesting are measurements of the metallicity of GRB host with z\gtrsim 4.7, since it has recently been shown that damped Lymann-α absorbers have a rapid decrease in metallicity at this redshift (Rafelski et al. 2013). In this paper measurements of the amount of metals and dust in the host galaxy of GRB 111008A at z=5.0 is presented, and it is discussed how observations of more high-z GRB host galaxies can give clues about dust formation mechanisms and the distribution of metals in the early Universe.
