GCG and macrothrombocytopenia and granulocyte inclusions with or without nephritis or sensorineural hearing loss: Fasting plasma GLP-1 (3.286 ± 0.706 for SBS patients vs 1.553 ± 0.063 for controls, P < 0.05 in Mann-Whitney test) and GLP-2 (3.664 ± 0.716 for SBS patients vs 1.394 ± 0.252 for controls P < 0.05 in Mann-Whitney test) concentrations were both higher in SBS patients than in controls subjects (see also Supplemental Figure S2C,E).
