          Abstract

          Resumen Introducción: el principal problema de salud pública en México es la obesidad y sus enfermedades asociadas, incluyendo las bucales. Objetivo: evaluar el efecto del tratamiento con metformina en pacientes obesos de clase I sobre la actividad de las metaloproteinasas presentes en el periodonto con periodontitis crónica. Métodos: se realizó un estudio clínico con 68 pacientes mujeres con obesidad de clase I y enfermedad periodontal. Se dividieron en 4 grupos; a 2 de ellos, además del tratamiento periodontal, se les administro metformina de 850 mg al día durante seis semanas. Se tomaron 2 muestras por paciente de tejido periodontal antes y después de cada tratamiento y se midió el índice de masa corporal (IMC), el índice de placa dentobacteriana y de inflamación. Mediante zimografía en gel de acrilamida se midió la actividad de las metaloproteinasas en la muestra de tejido recolectada. Los datos obtenidos fueron analizados mediante estadística descriptiva t de student para muestras relacionadas y se realizó ANOVA de una vía considerando p < 0,01 como estadísticamente significativa. Resultados: en el grupo de pacientes a las que se les administro metformina al final del tratamiento se observó una disminución del índice de masa corporal, del grado de inflamación y menor actividad de metaloproteinasas respecto al grupo control (65% frente a 25%; p < 0,01). Conclusiones: el tratamiento con metformina en pacientes con obesidad de clase I y enfermedad periodontal disminuye el IMC, mejora los síntomas de la periodontitis crónica y disminuye la actividad de las metaloproteinasas 1, 3, 8 y V presentes en el periodonto de estos pacientes.

          Abstract Introduction: in Mexico the main problem in public health is obesity and other diseases that are associated whit this condition, including oral health. Objective: to evaluate the effect of metformin treatment in patients with class I obese on the activity of metalloproteinases present in periodontium with chronic periodontitis. Methods: a clinical study was conducted in 68 patients with class I obesity and periodontal disease. They were divided into 4 groups. 2 of them, in addition to the periodontal treatment, were administered metformin 850 mg per day for six weeks; 2 samples were taken per patient of periodontal tissue before and after each treatment, body mass index, plaque index and inflammation were measured. Acrylamide gel zymography was used to measure the activity of metalloproteinases in the sample of tissue collected. The data obtained were analyzed by descriptive statistics, student t for related samples and one-way ANOVA was performed considering p < 0.01 as statistically significant. Results: in the group of patients who were administered metformin at the end of the treatment, there was a decrease in the body mass index, the degree of inflammation and lower metalloproteinase activity, compared with the control group (65% vs 25%; < 0.01). Conclusions: treatment with metformin in patients with obesity class I and periodontal disease decreases BMI, improves the symptoms of chronic periodontitis and decreases the activity of metalloproteinases 1, 3, 8, V present in periodontium of these patients.

          Matrix metalloproteinases (MMPs) in oral diseases.

          Matrix metalloproteinases (MMPs) are a group of enzymes that in concert are responsible for the degradation of most extracellular matrix proteins during organogenesis, growth and normal tissue turnover. The expression and activity of MMPs in adult tissues is normally quite low, but increases significantly in various pathological conditions that may lead into unwanted tissue destruction, such as inflammatory diseases, tumour growth and metastasis. MMPs have a marked role also in tissue destructive oral diseases. The role of collagenases, especially MMP-8, in periodontitis and peri-implantitis is the best-known example of the unwanted tissue destruction related to increased presence and activity of MMPs at the site of disease, but evidence has been brought forward to indicate that MMPs may be involved also in other oral diseases, such as dental caries and oral cancer. This brief review describes some of the history, the current status and the future aspects of the work mainly of our research groups looking at the presence and activity of various MMPs in different oral diseases, as well as some of the MMP-related aspects that may facilitate the development of new means of diagnosis and treatment of oral diseases.

            Zymography methods for visualizing hydrolytic enzymes.

            Zymography is a technique for studying hydrolytic enzymes on the basis of substrate degradation. It is a powerful, but often misinterpreted, tool yielding information on potential hydrolytic activities, enzyme forms and the locations of active enzymes. In this Review, zymography techniques are compared in terms of advantages, limitations and interpretations. With in gel zymography, enzyme forms are visualized according to their molecular weights. Proteolytic activities are localized in tissue sections with in situ zymography. In vivo zymography can pinpoint proteolytic activity to sites in an intact organism. Future development of novel substrate probes and improvement in detection and imaging methods will increase the applicability of zymography for (reverse) degradomics studies.

              Obesity prevalence in Mexico: impact on health and economic burden.

              Along with other countries having high and low-to-middle income, Mexico has experienced a substantial change in obesity rates. This rapid growth in obesity prevalence has led to high rates of obesity-related diseases and associated health-care costs.
