GDNF and Hyperglycemia: We identify GDNF and several plasma analytes, dominated by chemokines, that are associated with hyperglycemia over several months p.i. We provide leads involving inflammatory processes, as well as potentially dysregulated liver glucose homeostasis, that warrant further investigation to improve our understanding of how early inflammatory and metabolic responses against SARS-CoV-2 infection influence its severity and long-term metabolic complications.
