3. INTRODUCCION
La heterogeneidad y complejidad de la fisiopatológica de la Diabetes Mellitus hace que
el tratamiento sea desde su diagnostico un abordaje de múltiples cambios en el
estilo de vida hasta la presencia de tratamiento combinados multifactoriales.
Dentro del diagnostico de la Diabetes Mellitus es evidente que se incluyen fenotipos
con una base genética, fisiopatología y comportamiento clínicos muy diferentes. Así
mismo, el momento de la historia natural de la enfermedad en el que se encuentra
cada paciente demanda medidas diferentes.
En las últimas décadas el tratamiento farmacológico de la DM ha incorporado
interesantísimas nuevas opciones, tanto como modificaciones de clases terapéuticas ya
conocidas (nuevas insulinas, sulfonilureas…) como por la aparición de familias de
fármacos con mecanismos de acción nuevos.
4. Eficacia de los tratamientos actuales de la diabetes
Eficacia antihiperglucemiante
El tratamiento intensivo dirigido a alcanzar un nivel de hemoglobina glucosilada
A1c (HbA1c) inferior al 7% disminuye sustancialmente la incidencia de enfermedad
micro vascular en pacientes con DM 2 .
La eficacia de los tratamientos orales para la DM (medida como reducción de
HbA1c) está en torno al 1% .
Si bien el tratamiento con insulina se ha considerado tradicionalmente como de
potencia hipoglucemiante ilimitada, en la práctica clínica es difícil conseguir el
objetivo de HbA1c con las estrategias y formulaciones actuales.
Incluso utilizando estrategias intensivas para el control de la DM2 como el
tratamiento con múltiples dosis de insulina basal-bolus se consigue una HbA1c <
7% en menos del 60% de los pacientes, como prueban los metanálisis .

epidemic and its consequences? What are the current shortcomings? Acta Diabetol 2009; 46: pp. 173-181
5. Eficacia hipoglucemiante de fármacos para la diabetes tipo 2
Fármaco Reducción media de HbA1c esperada (%)
Inhibidores de alfa glucosidasas 0,5-0,8
Metformina 1-1,5
Sulfonilureas/glinidas 1,0-1,5
Inhibidores de DPPIV 0,7-1,0
Glitazonas 0,7-1,5
Agonistas del receptor de GLP1 0,8-1,2
Insulina 1,0-2,0
Hemoglobina glicosilada VN : 4 a 5,6 %
6. Eficacia de los tratamientos actuales de la diabetes
Eficacia antihiperglucemiante
De los nuevos fármacos : los agonistas del receptor de GLP1 (GLP1ar) pueden
conseguir reducciones de HbA1c mayores que algunos fármacos orales (−0.97%
[intervalo de confianza del 95% −1,13 a −0,81%]),especialmente los GLP1ar de larga
duración respecto a los inhibidores de DPPIV . Además aportan ventajas asociadas
en reducción de peso y presión arterial.
Pero sigue siendo un tratamiento limitado por la presencia de efectos indeseados
gastrointestinales, coste y falta de experiencia de uso a largo plazo.

to metformin in subjects with type 2 diabetes-a review and metaanalysis. Diabetes Obes Metab 2012; 14: pp. 762-767
7. Eficacia en control global de factores de riesgo cardiovascular
El efecto beneficioso de la terapia intensiva sobre la enfermedad macrovascular no
está completamente probado.
Dos metanálisis que evaluaron el tratamiento estándar vs. intensivo en reducción de
riesgo cardiovascular (CV) concluyeron que la terapia intensiva redujo
significativamente el riesgo de eventos CV .
En 2013 se publicaron en New England Journal of Medicine los resultados del estudio
correspondientes al periodo 1999-2010 . Pese a constatar mejoría en estos años,
entre el 33,4 y el 48,7% de los pacientes no cumplen los objetivos relativos a control
glucémico (HbA1c), lipídico (colesterol LDL), peso y presión arterial.
En el Estudio español con 286.791 , solo el 12,1% de los adultos con DM2 alcanzan
los objetivos de HbA1c < 7%, colesterol LDL <100 mg/dL y presión arterial < 130/80
mmHg .

receptor del péptido similar al glucagón tipo 1); SUs: sulfonilureas.Fuentes: Modificado de Morgan C et al. 1
11. Tratamientos antihiperglucemiantes e hipoglucemia
Posiblemente el efecto adverso más limitante en el uso de fármacos para la DM es la
hipoglucemia.
Las insulinas y los agentes antidiabéticos orales se situaron en segundo y cuarto lugar
respectivamente en frecuencia como causas de ingresos hospitalarios .Los tratamientos
de tipo endocrinológico supusieron el 42,1% de todos los ingresos urgentes en esta
población, y en el 94,6% de ellos el motivo fue la hipoglucemia .
El riesgo de hipoglucemia es muy diferente según el tratamiento empleado y sus
combinaciones. Es menor con los tratamientos más recientes (incretinmiméticos,
inhibidores de la proteína cotransportador de sodio-glucosa tipo 2…) .
12. Riesgo de hipoglucemia asociado a diferentes tratamientos para la diabetes tipo 2

Inhibidores de dipeptidil peptidasa IV; GLP1ar: agonistas del receptor del péptido
similar al glucagón tipo 1; SUs: sulfonilureas; TZDs: tiazolidindionas.

hypoglycemia in type 2 diabetes. JAMA 2010; 303: pp. 1410-1418
13. Sostenibilidad de la eficacia a largo plazo: preservación de la célula beta
La pérdida de la secreción adecuada de insulina es el fenómeno fisiopatológico clave en
el comienzo y desarrollo de la DM 2.
En las personas con DM2 incluye alteraciones cualitativas (pérdida de la primera fase de
secreción en respuesta a la ingesta, pérdida de pulsatilidad normal…) y cuantitativas
(reducción de masa celular beta/reserva insular endógena).
La disminución de la reserva insular endógena marca la progresión en la historia natural
de la DM2 y la constante necesidad de incrementar el tratamiento farmacológico hasta la
introducción del tratamiento con insulina exógena .
Varias clases farmacológicas (Glitazonas, incretinmiméticos) han mostrado resultados in
vitro que indican mejoría en la masa/función celular beta .

37. DIABETES Y NUEVOS FARMACOS
Hasta el año 1920, en que se descubrió la insulina, no se disponía de fármacos , por casi
60 años solo hemos dispuesto de tres fármacos para su tratamiento :
1.- Insulina ( 1920 )
2.- Sulfonilureas ( 1955 )
3.- Biguanidas ( 1957 )
Luego aparecen :
4.- Inhibidores de las alfa glucosidasas ( 1990 )
5.- Tiazolidinedionas ( 1995 ) y glimepirida ( 1995 ) pioglitazona (
1997 )
6.- Metiglinidas ( repaglinida ,Neteglinida ) y aparece la primera
sulfonilurea modificada * Glicazida . ( 1997 )

38. DIABETES Y NUEVOS FARMACOS
En la década del 2000, De Fronzo describe al “octeto ominoso” 9 , para referirse a los
múltiples y complejos mecanismos patogénicos de la DM2.
Este mayor conocimiento de la fisiopatología de la DM2 da origen al desarrollo de nuevos
fármacos con novedosos mecanismos de acción.
7.- Farmacos con efecto incretina :
.- agonista del peptido similar al glucagon tipo 1 ( AR –GLP1 ) (
2005 )
.- Inhibidores de la dipeptidil peptidasa ( 2006 )
8.-Inhibidores de los cotransportadores de sodio-glucosa tipo 2 ( ISGLT 2 )
( 2012 )
9.- Agonista de la dopamina con mecanismos e accion central no bien
definidos ( 2013 )
10 .- Analogos de amilina ,que disminuyen el glucagon postprandial y el
vaciamiento gastrico ,con modesto efecto en la HBA1c . ( 2013 )
40. CANDIDATOS PARA LOS INHIBIDORES DE LA DPP4
1.- Los inhibidores de la DPP-4 no se consideran una terapia inicial .
2.-La terapia inicial en la mayoría de los pacientes con diabetes tipo 2 debe comenzar
con dieta, reducción de peso, ejercicio y metformina.(en ausencia de
contraindicaciones).
3.-Los inhibidores de DPP-4 se pueden considerar como monoterapia en pacientes que
son intolerantes o tienen contraindicaciones para la metformina, las sulfonilureas o las
tiazolidinIdiona, como los pacientes con enfermedad renal crónica o que tienen un
riesgo particularmente alto de hipoglucemia.
4.-Los inhibidores de DPP-4 se pueden considerar como terapia farmacológica
complementaria para pacientes que no están controlados adecuadamente con
metformina, una tiazolidinIdiona o una sulfonilureas. Sin embargo, su modesta eficacia
y gasto para disminuir la glucemia disminuyen nuestro entusiasmo por estos
medicamentos.

41. Incretinas
Son hormonas enteroendócrinas producidas en el intestino en
respuesta a una comida ( es decir, en presencia de glucosa):
GLP-1 (Glucagon like peptide 1)
GIP (Glucose dependent insulinotropic peptide)
Mantienen el control glucémico aumentando la producción de insulina y
disminuyendo la producción de glucagon en respuesta a una elevación de
la glucemia.
Estudios experimentales in vitro han demostrado que las incretinas
tienen un papel importante en la replicación de las células beta y en el
descenso de la apoptosis, aunque la relevancia clínica de esto en
pacientes con diabetes tipo 2 es desconocido.
GLP-1 y GIP
42. La glucosa oral estimula en mayor medida la secreción de insulina ( en
comparación con la vía IV)
El “efecto incretina” es responsable de 50-70% de la insulina secretada
dependiente de glucosa
La enzima DPP 4 es responsable de la degradación rápida de las
incretinas biológicamente activa (en menos de dos minutos).
En la DM tipo 2, el “efecto incretina” esta ausente o reducido de
manera significativa

Potential sequences of antihyperglycemic therapy for patients with type 2 diabetes are displayed, the usual transition being vertical, from top to bottom (although horizontal movement within therapy stages is also possible, depending on the circumstances). The figure denotes relative glucose lowering efficacy, risk of hypoglycemia, effect on body weight, other side effects and approximate relative cost for each drug class.
In most patients, begin with lifestyle changes; metformin monotherapy is added at, or soon after, diagnosis, unless there are contraindications.

Here is a diagrammatic representation of the approximate pharmacokinetic properties of various insulin formulations. Understanding the onset, peak and duration of action of insulin products is key for successful management of patients with diabetes.
Basal insulin alone is usually the optimal initial regimen, beginning at 0.1-0.2 U/kg body weight, depending on the degree of hyperglycemia. It is usually prescribed in conjunction with 1-2 non-insulin agents, although insulin secretagogues (sulfonylureas, meglitinides) are typically stopped once more complex regimens beyond basal insulin are utilized.
In patients still not at target after basal insulin has been adequately titrated, and the patient is willing to take >1 injections, there are several options. First, consider GLP-1 receptor agonists (see Fig. 2). The combination of basal insulin + GLP-1RA is becoming well established after several studies confirmed its efficacy on par with more complex multi-dose insulin regimens, but with less hypoglycemia and with weight loss instead of weight gain. If such an approach is not possible or has been tried and proven unsuccessful, there are 3 possible advanced insulin regimens:
Adding 1 injection of a rapid acting insulin analogue before the largest meal,
Adding 2-3 injections of a rapid acting insulin analogue before 2-3 meals, or
Using premixed insulin BID
Each approach has its advantages and disadvantages. The figure describes the number of injections required at each stage, together with the relative complexity and flexibility.
A fourth, less common method (not shown) is referred to as ‘self-mixed split’ and involves 2 injections of NPH mixed with regular human insulin (or mixed with a rapid acting insulin analogue), administered before breakfast and the evening meal. This is a more cost-effective approach, using human insulins in vials, and allows self-adjustment by the patient of the short/rapid-acting component, based on pre-meal blood glucose or anticipated carbohydrate intake (or both.)
Once a strategy is initiated, titration of the insulin dose is important, with dose adjustments made based on the prevailing BG levels as reported by the patient.
Comprehensive education regarding self-monitoring of BG, diet, exercise, and the avoidance of, and response to, hypoglycemia are critical in any patient on insulin therapy.
