ABSTRACT
In human medicine, diagnosis of diabetic ketoacidosis (DKA) is usually based on measurement of capillary 3-beta-hydroxybutyrate (3-HB) with a hand held ketone sensor. This study was conducted to determine if measurement of capillary 3-HB could be useful for the diagnosis and monitoring of canine DKA. Fifteen dogs with diabetic ketosis and 10 with DKA were evaluated. Paired measurements of 3-HB of capillary and venous blood samples were analysed by the electrochemical sensor and reference method. Use of capillary 3-HB measurement during DKA management was then evaluated through simultaneous measurements of capillary 3-HB, urinary AcAc and venous blood gas analysis. Good agreement between capillary and venous 3-HB measurement was detected by the electrochemical sensor and reference method. Monitoring treatment of DKA revealed a significant correlation between capillary 3-HB and acidosis markers, while no significant correlation was observed between AcAc and acidosis markers. A cut-off value of capillary blood 3-HB >3.8 mmol/L for diagnosis of DKA resulted in 70% and 92% sensitivity and specificity. The electrochemical sensor accurately measures 3-HB concentration in both capillary and venous blood samples, is accurate in diagnosing canine DKA, and appears to reflect the patient's metabolic status during DKA treatment.

Desde la salud pública, los programas de detección para diabetes mellitus tipo 2 son un recurso para su vigilancia. La Secretaría de Salud Nacional implementó como estrategia de tamizaje el Programa de Acción Diabetes Mellitus (PADM-2), el cual se basa en dos pruebas secuenciales: Cuestionario de Factores de Riesgo y medición de glucemia capilar. En este trabajo, se exploró la capacidad del PADM-2 como estrategia de tamizaje. El estudio se efectuó en el año 2005, participaron 1.562 individuos que asistieron a seis unidades del primer nivel de atención de la Secretaría de Salud del Gobierno del Distrito. Se consideró como el estándar de oro a la glucosa sérica en ayuno. Al valorar las dos pruebas en serie, la sensibilidad fue de 98 por ciento, la especificidad de 58,7 por ciento, y el valor predictivo positivo de 16,6 por ciento. El valor predictivo positivo apunta a que una alta proporción del gasto se destina a detectar falsos positivos, lo cual hace necesario replantearse los criterios utilizados en el PADM-2, de tal manera que se obtenga un mayor beneficio económico y social.
From the public health perspective, programs to detect type 2 diabetes mellitus are a prime resource for surveillance of the disease. As a screening strategy, the Mexican Ministry of Health implemented the Diabetes Mellitus Action Program (PADM-2), based on two sequential tests: the Risk Factor Questionnaire and capillary blood glucose test. This study explored the Program's capacity as a screening strategy. The study was carried out in the year 2005, with a sample of 1,562 that attended six primary care units under the Health Secretariat of the Federal District. Fasting serum glucose was defined as the gold standard. When assessing the two tests sequentially, sensitivity was 98 percent, specificity 58.7 percent, and positive predictive value 16.6 percent. The positive predictive values indicates that a high proportion of the expenditure still goes to detecting false-positives, thus requiring reconsideration of the Program's criteria to obtain a greater economic and social benefit.

O trabalho visa avaliar eficácia e a preferência dos pacientes na monitorização da glicemia capilar em locais alternativos: lóbulo de orelha, antebraço e panturrilha em relação à ponta de dedo. Foram avaliados 89 pacientes (39 M/50 F) com diabetes melito tipo 2 (DM2). A monitorização foi feita com glicosímetro digital (ACCU - CHEK Performa, Roche), lancetador ACCU-CHEK Multiclix, em grau 5 na face palmar da falange distal do 3º dedo da mão direita, porção inferior do lóbulo da orelha direita, antebraço direito e região superior da panturrilha direita. Não houve diferença da glicemia capilar na ponta de dedo em relação aos locais alternativos. A ponta de dedo foi o local mais doloroso. Quanto ao local de preferência, a orelha e a ponta de dedo foram os preferidos. A monitorização glicêmica em locais alternativos é simples, segura e eficaz, como a glicemia de ponta de dedo.
This paper evaluate the efficacy and patients preferences of glucose monitoring in alternatives sites: ear lobe, forearm and calf against conventional fingerstick. We studied 89 patients (39 M/ 50 F) with type 2 diabetes mellitus (DM2). Glucose monitoring was measured using a digital glucosimeter (ACCU - CHEK Performa, Roche), and ACCU-CHEK Multiclix lancetador, with grade 5 on the distal phalange on the right hand's third finger, inferior part of right ear lobe, right forearm and right calf. There was not statistical significance on the comparative analyzes of fingerstick and alternatives sites. There was more pain in fingerstick. The patients preferred the fingerstick and the ear lobe. Glucose monitoring in alternative sites is as simple, safe and efficient as fingerstick.
