Proton MR spectra and biochemical assays have been recorded on the sera of 40 patients and ten controls in order to document the correlation between spectroscopic and biochemical variations in selected pathologies (cancer, inflammatory and infectious diseases, diabetes). N-acetyl proton resonances are essentially generated by the N-acetyl residues of the glucidic moieties borne by the most abundant acute-phase proteins (alpha1-acid glycoprotein, alpha1-antitrypsin and haptoglobin). These resonances are not correlated to immunoglobulins A, G and M levels. Principal component analysis shows that variations in spectroscopic and biochemical data are independent markers of the inflammatory status of patients but no additional sensitivity or specificity is obtained when the two sets of data are combined.
