ABSTRACT
UNLABELLED: Diabetes mellitus type 2 is the most common metabolic disorder and it causes an important morbimortality. The structural modifications in the parotid gland (sialosis) had already been described in these patients and could result in variations in the salivary composition, as well as an increase in periodontal and dental pathology. OBJECTIVES: To compare the biochemical findings in the saliva and to correlate these biochemical disturbances with the morphologic findings previously described. PATIENTS AND METHODS: Clinical information were gathered about 33 patients, 17 had type 2 diabetes. Samples of whole saliva were obtained for biochemical analysis and serum samples to determine metabolic control. RESULTS: In the diabetics saliva we found urea and total proteins increased and reduced levels of microalbumina. Salivary glucose was only augmented in patients with poor metabolic control. Clinical symptoms of xerostomia were present in 76,4% and dental and periodontal disease in 100%. The parotid gland was characterised by the presence of small acini, lipid intracytoplasmic droplets, as well as adipose stroma infiltration. The acinar cytoqueratins expression was heterogeneous and very positive in the hyperplasic ducts. CONCLUSIONS: These biochemical disorders in the saliva of the type 2 diabetic patients would be related with the structural changes previously observed in parotid glands.

La diabetes mellitus tipo 2 es el desorden metabólico más frecuente, siendo además causante de una importante morbi-mortalidad. En estos pacientes se han descrito alteraciones estructurales de la parotida (sialosis) que podrían comportar modificaciones en la composición salivar, así como un incremento de patología dental y periodontal. Objetivos: establecer las alteraciones bioquímicas de la saliva y su posible correlación con los hallazgos morfológicos. Diseño del estudio: se realizo un estudio clínico de 33 pacientes, 17 de ellos con diabetes tipo 2. Se recogieron muestras de saliva para análisis bioquímico y suero para control metabólico.Resultados: en la saliva de los pacientes diabéticos encontramos un incremento de la urea y las proteínas totales, así como una reducción de la microalbumina. La glucosa salivar estaba solo aumentada en los diabéticos con mal control metabólico. Los síntomas de xerostomía se detectaron en el 76,4% de los casos y las lesiones dentales y periodontales en el 100% de los pacientes. Conclusión: estos desordenes bioquímicos en la saliva de los pacientes con diabetes tipo 2 se pueden correlacionar con las alteraciones estructurales descritas previamente
