2 Aumento de la Expectativa de Vida e Impacto Global
Global Burden Disease. Murray y López Países desarrollados : disminución 25% menores de 15 ,incremento 71% mayores de 65. Países en desarrollo incremento 25% menores de 15 e incremento 140% 45 a 59. Poblaciones España e Italia 80 a 105 años. Japón 2002: 17,934 personas de 100 años.

3 Cambios Fisiológicos Disminución de la compliance de la pared torácica y el sistema respiratorio,así como del retroceso elástico resultan en atrapamiento aéreo ( incremento de VR ). Incremento de la CRF y del trabajo respiratorio. Afección de la musculatura respiratoria,cambios en la geometría de la caja torácica,estado nutricional, función cardíaca : sarcopenia. >80 años :PIM valores críticos bajos, hipoventilación alveolar.

4 Cambios Fisiológicos Disminuyen las tasas de PEF , y las curvas flujo-volumen sugieren colapso de la vía aérea periférica. El intercambio gaseoso es remarcablemente mejor conservado en reposo y durante el ejercicio a expensas de reducir la superficie alveolar e incrementar el desequilibrio ventilo-perfutorio. Disminución de la sensibilidad de los centros respiratorios a la hipoxemia e hipercapnia, puede resultar en rpta. ventilatoria disminuída en enfermedad aguda o agravar la obstrucción de la vía aérea.

6 Asma en Ancianos Por muchos años considerada enfermedad de niños y jóvenes e infrecuente en la ancianidad. Los Asmáticos ancianos generalmente son aquéllos que adquirieron la enfermedad en la niñez o la adolescencia ,en quienes la enfermedad progresó en el tiempo o se reactivó después de períodos de remisión; sin embargo las primeras manifestaciones de asma pueden ocurrir también después de los 65 años de edad.

7 Asma en Ancianos La presunción de baja prevalencia puede atribuirse a las grandes dificultades para encontrar un diagnóstico correcto en el geronte. Las razones por la que el Asma no es diagnosticado en al adulto mayor , no están claras. Confusión de síntomas Subestimados por el médico Falta de evaluación funcional apropiada. PUEDE DEBERSE A LA CONFUSION CON EPOC

8 Epidemiología Puede ser diagnosticada a cualquier edad y es común en el anciano. Una serie de estudios poblacionales han expuesto que la prevalencia de asma en ancianos es similar a la de otros grupos etáreos 4.5-8%. Diagnosticados como nuevos 0.1% por encima de los 65 años de edad.

9 Asma en el Geronte Puede clasificarse en :
Asma de “inicio tardío” aparición de novo después de los 65 años. Asma de comienzo temprano, continúa una enfermedad que comenzó antes de los 65 años. La relevancia de ésta clasificación es que la enfermedad puede ser severa en persistentes crónicos.

10 Asma en Anciano Diagnóstico
Considerar en todo caso de : Disnea inexplicada Sibilancias Tos nocturna. ( Nivel de Evidencia III ). Revisión cuidadosa en debut reciente : Medicación ASA , AINES ( Nivel de Evidencia II ).

11 Asma en Anciano Diagnóstico
Puede complicarse por diversos factores ,tales como: Síntomas no específicos, comunes a otras patologías. La presencia de enfermedades coexistentes. Diferenciación con EPOC Alteraciones en la percepción de los síntomas en ancianos Menor incidencia de asma y atopía en la tercera edad.

12 Asma en Anciano Diagnóstico
Los tests de función pulmonar tienen un rol muy importante y son fundamentales. Espirometría. Problemas de comprensión y de pobre coordinación afectan sus resultados.

13 Asma en Anciano Diagnóstico
Historia Clínica minuciosa. Laboratorio. Radiografía de tórax frente y perfil. Electrocardiograma. Espirometría. Establecer diagnósticos diferenciales. Puntualizar patologías subyacentes:terapeúticas, dosis, vías, etc.

14 Planes de Tratamiento Consideraciones Especiales
Disminución de la respuesta a estímulos especiales Trastornos de la memoria Pérdida de la coordinación y la fuerza muscular que afecta el uso de algunos dispositivos inhalatorios. Dificultades visuales y auditivas Dificultades del sueño que pueden afectar la esfera cognitiva Trastornos depresivos Elección de la medicación personalizada.

15 Diagnóstico Diferencial
Falla ventricular Izquierda Cáncer pulmonar Reflujo Gastroesofágico Fibrosis Pulmonar Bronquiectasias Tromboembolismo Pulmonar Tuberculosis.

16 Consideraciones Especiales del Manejo Terapeútico
Pacientes polimedicados, mayor cantidad de reacciones adversas e interacciones medicamentosas. Tener en cuenta para las dosis, integridad de la función hepática y renal , para evitar eventos adversos por la metabolización o excreción de las drogas.

17 Objetivos del manejo Prevenir síntomas de asma crónica
Optimizar la función pulmonar Mantener los niveles de actividad normal Minimizar los efectos colaterales de la medicación Reducir o eliminar las exacerbaciones y reconocerlas tempranamente Evitar el agravamiento de las patologías subyacentes.

24 Step 1 – As-needed reliever medication
Treating to Achieve Asthma Control Step 1 – As-needed reliever medication Patients with occasional daytime symptoms of short duration A rapid-acting inhaled β2-agonist is the recommended reliever treatment (Evidence A) When symptoms are more frequent, and/or worsen periodically, patients require regular controller treatment (step 2 or higher)

25

26 Treating to Achieve Asthma Control
Step 2 – Reliever medication plus a single controller A low-dose inhaled glucocorticosteroid is recommended as the initial controller treatment for patients of all ages (Evidence A) Alternative controller medications include leukotriene modifiers (Evidence A) appropriate for patients unable/unwilling to use inhaled glucocorticosteroids

27

28 Treating to Achieve Asthma Control
Step 3 – Reliever medication plus one or two controllers For adults and adolescents, combine a low-dose inhaled glucocorticosteroid with an inhaled long-acting β2-agonist either in a combination inhaler device or as separate components (Evidence A) Inhaled long-acting β2-agonist must not be used as monotherapy For children, increase to a medium-dose inhaled glucocorticosteroid (Evidence A)

29 Treating to Achieve Asthma Control
Additional Step 3 Options for Adolescents and Adults Increase to medium-dose inhaled glucocorticosteroid (Evidence A) Low-dose inhaled glucocorticosteroid combined with leukotriene modifiers (Evidence A) Low-dose sustained-release theophylline (Evidence B)

30

31 Treating to Achieve Asthma Control
Step 4 – Reliever medication plus two or more controllers Selection of treatment at Step 4 depends on prior selections at Steps 2 and 3 Where possible, patients not controlled on Step 3 treatments should be referred to a health professional with expertise in the management of asthma

32 Treating to Achieve Asthma Control
Step 4 – Reliever medication plus two or more controllers Medium- or high-dose inhaled glucocorticosteroid combined with a long-acting inhaled β2-agonist (Evidence A) Medium- or high-dose inhaled glucocorticosteroid combined with leukotriene modifiers (Evidence A) Low-dose sustained-release theophylline added to medium- or high-dose inhaled glucocorticosteroid combined with a long-acting inhaled β2-agonist (Evidence B)

33

34 Treating to Achieve Asthma Control
Step 5 – Reliever medication plus additional controller options Addition of oral glucocorticosteroids to other controller medications may be effective (Evidence D) but is associated with severe side effects (Evidence A) Addition of anti-IgE treatment to other controller medications improves control of allergic asthma when control has not been achieved on other medications (Evidence A)

35 Treating to Maintain Asthma Control
When control as been achieved, ongoing monitoring is essential to: - maintain control - establish lowest step/dose treatment Asthma control should be monitored by the health care professional and by the patient

36 Treating to Maintain Asthma Control
Stepping down treatment when asthma is controlled When controlled on medium- to high-dose inhaled glucocorticosteroids: 50% dose reduction at 3 month intervals (Evidence B) When controlled on low-dose inhaled glucocorticosteroids: switch to once-daily dosing (Evidence A)

37 Treating to Maintain Asthma Control
Stepping down treatment when asthma is controlled When controlled on combination inhaled glucocorticosteroids and long-acting inhaled β2-agonist, reduce dose of inhaled glucocorticosteroid by 50% while continuing the long-acting β2-agonist (Evidence B) If control is maintained, reduce to low-dose inhaled glucocorticosteroids and stop long-acting β2-agonist (Evidence D)

38 Treating to Maintain Asthma Control
Stepping up treatment in response to loss of control Rapid-onset, short-acting or long-acting inhaled β2-agonist bronchodilators provide temporary relief. Need for repeated dosing over more than one/two days signals need for possible increase in controller therapy

39 Treating to Maintain Asthma Control
Stepping up treatment in response to loss of control Use of a combination rapid and long-acting inhaled β2-agonist (e.g., formoterol) and an inhaled glucocorticosteroid (e.g., budesonide) in a single inhaler both as a controller and reliever is effecting in maintaining a high level of asthma control and reduces exacerbations (Evidence A) Doubling the dose of inhaled glucocortico-steroids is not effective, and is not recommended (Evidence A)

40 Asthma Management and Prevention Program Component 3: Assess, Treat and Monitor Asthma – Children 5 Years and Younger Childhood and adult asthma share the same underlying mechanisms. However, because of processes of growth and development, effects of asthma treatments in children differ from those in adults.

41 Asthma Management and Prevention Program Component 3: Assess, Treat and Monitor Asthma – Children 5 Years and Younger Many asthma medications (e.g. glucocorticosteroids, β2- agonists, theophylline) are metabolized faster in children than in adults, and younger children tend to metabolize medications faster than older children

42 Asthma Management and Prevention Program Component 3: Assess, Treat and Monitor Asthma – Children 5 Years and Younger Long-term treatment with inhaled glucocorticosteroids has not been shown to be associated with any increase in osteoporosis or bone fracture Studies including a total of over 3,500 children treated for periods of 1 – 13 years have found no sustained adverse effect of inhaled glucocorticosteroids on growth

43 Asthma Management and Prevention Program Component 3: Assess, Treat and Monitor Asthma – Children 5 Years and Younger Rapid-acting inhaled β2-agonists are the most effective reliever therapy for children These medications are the most effective bronchodilators available and are the treatment of choice for acute asthma symptoms

44 Asthma Management and Prevention Program Component 4: Manage Asthma Exacerbations
Exacerbations of asthma are episodes of progressive increase in shortness of breath, cough, wheezing, or chest tightness Exacerbations are characterized by decreases in expiratory airflow that can be quantified and monitored by measurement of lung function (FEV1 or PEF) Severe exacerbations are potentially life-threatening and treatment requires close supervision

45 Treatment of exacerbations depends on: The patient
Asthma Management and Prevention Program Component 4: Manage Asthma Exacerbations Treatment of exacerbations depends on: The patient Experience of the health care professional Therapies that are the most effective for the particular patient Availability of medications Emergency facilities

46 Primary therapies for exacerbations:
Asthma Management and Prevention Program Component 4: Manage Asthma Exacerbations Primary therapies for exacerbations: Repetitive administration of rapid-acting inhaled β2-agonist Early introduction of systemic glucocorticosteroids Oxygen supplementation Closely monitor response to treatment with serial measures of lung function

47 Asthma Management and Prevention Program Special Considerations
Special considerations are required to manage asthma in relation to: Pregnancy Surgery Rhinitis, sinusitis, and nasal polyps Occupational asthma Respiratory infections Gastroesophageal reflux Aspirin-induced asthma Anaphylaxis and Asthma

48 Asthma Management and Prevention Program: Summary
Asthma can be effectively controlled in most patients by intervening to suppress and reverse inflammation as well as treating bronchoconstriction and related symptoms Although there is no cure for asthma, appropriate management that includes a partnership between the physician and the patient/family most often results in the achievement of control

49 Asthma Management and Prevention Program: Summary
A stepwise approach to pharmacologic therapy is recommended. The aim is to accomplish the goals of therapy with the least possible medication The availability of varying forms of treatment, cultural preferences, and differing health care systems need to be considered

50 EPOC y Asma en Ancianos Comparten similitudes clínicas y funcionales
Presentaciones patológicas diferentes : dos enfermedades distintas. No se puede excluir la coexistencia de ambas enfermedades. Importante reconocerlas y distinguirlas tempranamente para el tratamiento apropiado.

52 EPOC es la unica causa de muerte que se ha incrementado significativamente en los últimos años.
Cambio en edad ajustado a tasa de muerte en USA, de 1965 a 1998 (%) +163 160 120 80 40 These data from the USA, collected from 1965 to 1998, show a 163% increase in age-adjusted death rates from chronic obstructive pulmonary disease (COPD). While the death rate is declining from diseases such as coronary heart disease (CHD) (a 59% decrease) and cerebrovascular disease (CVD) (a 35% decrease), the death rate from COPD is increasing markedly. All other causes of age-adjusted US deaths also saw a decline of 7%. It may that this is partly a feature of increased recognition of COPD including an increase in the mention of the term on death certificates, but this does not detract from the overall trends illustrated in the figure. The Global Burden of Disease (GBD) study attributed more than 2.2 million deaths to COPD in 1990 (4.4% of worldwide deaths), ranking COPD as the sixth most serious cause of worldwide mortality.1 Furthermore, the 2004 World Health Organization (WHO) report indicated that COPD deaths are on the increase, with over 2.7 million deaths (4.8%) in Even more concerning, COPD deaths are projected to rise to third place in the worldwide ranking with 4.5 million deaths in The 2004 American Lung Association Report estimated approximately 120,000 deaths in the USA in The European Lung White Book, the first comprehensive survey on respiratory health in Europe, estimated annual COPD mortality in Europe as 200,000–300,000.4 References Murray CJ, Lopez AD.

54 Resultados de las Exacerbaciones de la EPOC
Mortalidad Hospitalaria 20%-24% (1 año) En pacientes UCI En pacientes Hospitalizados Mortalidad Hospitalaria 2.5%-10% (5 días) Treatment failure is defined as not responsive to initial treatment(s). Outcomes = health utilizations. This slide shows outcomes of patients with acute exacerbations: 20-24% of patients in the ICU with an exacerbation died; 6-12% of patients in general hospital beds, not ICU beds, died. Of those who visited the ER for an acute exacerbation, 22-32% of those patients had to revisit the emergency room after being discharged. Those who were treated as outpatients 13-33% of those patients did not response to initial treatments and needed further medical intervention. Main point: Acute exacerbations are a serious matter and should be of concern to the health care provider.
