SMART metodo nauda astmos kontrolei Brigita Šitkauskienė ir Kęstutis Malakauskas Kauno medicinos universitetas

Astmos gydymo tikslas Astmos kontrolė - nėra simptomų - nėra paūmėjimų - normalus fizinis aktyvumas Naudojant mažiausią efektyvią vaistų dozę

Vyresnių nei 5 metų vaikų ir suaugusiųjų astmos gydymo pakopos 1 pakopa 2 pakopa 3 pakopa 4 pakopa 5 pakopa Pacientų ir jų šeimos narių mokymas; Aplinkos veiksnių kontrolė Greitai veikiantis beta-2 agonistas esant poreikiui Kontroliuojamo vaisto pasirinkimas Pasirinkti viena vaistą (ar derinį) Pridėti vieną ar daugiau vaistų Pridėti vieną ar abu vaistus Pasirinkti vieną vaistą Vidutinė ar didelė IKS dozė ir IVBA Maža IKS dozė ir IVBA Mažiausia geria- mojo KS dozė Maža IKS dozė Leukotrienų receptorių antagonistus Vidutinė ar didelė IGKS dozė Leukotrienų receptorių antagonistus Anti-IgE vaistas Maža IKS dozė ir leukotrienų receptorių antagonistus Lėtai atsipalaiduojantis Maža IKS dozė ir lėtai atsipalaiduojantis teofilinas

Astmos gydymas - pakopinis SMART astmos gydymo būdas: Tradicinis astmos gydymas: Symbicort + Symbicort IKS + TVBA Sudėtinis preparatas (Seretide arba Symbicort) + TVBA SMART = Symbicort Maintenance And Reliever Therapy, Symbicort nuolatiniam astmos gydymui ir simptomams slopinti

Symbicort SMART Symbicort Maintenance And Reliever Therapy Symbicort nuolatiniam astmos gydymui ir simptomams palengvinti Formoterolis (greitas simptomų slopinimas ir ilgai trunkantis bronchus plečiantis poveikis) Nereikia papildomo inhaliatoriaus simptomams slopinti Budezonidas (priešuždegiminis vaistas, pradeda veikti per keletą valandų*) Symbicort vartojimas “pagal poreikį” profilaktiškai prieš fizinį krūvį neindikuotinas *Gibson P. et al, AJRCCM 2001, 163, 32-36

SMART Galimybių langas apsaugoti nuo astmos paūmėjimų Daugiausiai simptomų Pacientų, kuriems buvo nustatytas paūmėjimas duomenys n=1596 Dažnėjantys, keliantys nerimą simptomai SMART Atsistatymas Pavieniai, „įspėjantys” simptomai Vidutinė trukmė: 5,7 d. Vidutinė trukmė: 5,7 d. Van der Molen T, Partridge MR, Myrseth SE and Busse W. ERS , 2005

Tyrimuose dalyvavo lengva, ir sunkia astma sergantys pacientai Symbicort SMART patvirtinta klinikiniais tyrimais, kuriuose dalyvavo apie 15000 pacientų Tyrimuose dalyvavo lengva, vidutinio sunkumo ir sunkia astma sergantys pacientai 2001 2008 SMART = Symbicort Maintenance And Reliever Therapy, Symbicort nuolatiniam astmos gydymui ir simptomams slopinti

This improvement was similar between treatment groups in both studies.1,2 The improvements in daily asthma control was achieved at a lower steroid load in the Symbicort SMART groups compared with the ICS/LABA+SABA groups. 1.

Symbicort SMART® reduces the rate of severe exacerbations compared with higher doses of ICS/LABA plus SABA This slide illustrates the effect Symbicort SMART has on the rate of severe exacerbations compared with higher doses of ICS/LABA in studies conducted by Kuna et al.1 and Bousquet et al.2 The total doses of ICS used are presented in the slide, ie a lower dose of ICS was used in the Symbicort SMART groups compared to the other groups. Severe exacerbations in both studies were defined as a deterioration in asthma resulting in hospitalisation/ER treatment or the need for oral steroids for ≥3 days. In the study by Kuna et al. patients (n=3335) were randomised to treatment with Symbicort SMART (160/4.5 µg bid+as needed), fixed-dose Seretide™ (50/250 µg bid) or fixed-dose Symbicort® (320/9 µg bid), both plus SABA as needed.1 The total number of severe exacerbations was significantly reduced by 39% with Symbicort SMART compared with fixed-dose Seretide (p<0.001) and by 28% compared with fixed-dose Symbicort (p<0.01).1 Bousquet et al. randomised patients (n=2309) to Symbicort SMART (2 x 160/4.5 µg bid) or high-dose Seretide (50/500 µg bid) plus SABA as needed.2 Treatment with Symbicort SMART led to a 21% statistically significant reduction in severe exacerbations compared with maximum-dose Seretide (p<0.05).2 1.

Gydant Symbicort SMART suvartojama mažiau steroidų palyginus su IKS/IVBA + TVBA IKS kiekis (BDP ekvivalentas) Geriamų steroidų dienos Seretide + TVBA Symbicort + TVBA Symbicort SMART 2000 1500 1600 1200 1200 900 600 800 FP 500 mcg/d FP 1000 mcg/d The benefits of Symbicort SMART® are achieved at a lower overall steroid load compared with higher dose ICS/LABA plus SABA The range of daily mean beclomethasone dipropionate (BDP)-equivalent ICS doses were calculated based on Global Initiative for Asthma (GINA) estimations of equipotence of ICS in metered doses: fluticasone(FP) 500 µg=budesonide 800 µg=BDP 1000 µg.3 In the study by Kuna et al., Symbicort SMART-treated patients had a 25% significantly lower daily ICS load compared with fixed-dose Seretide or Symbicort (755 µg compared with 1000 µg [BDP-equivalent] in both fixed-dose treatment groups) (p<0.001).1 Bousquet et al. reported a 38% significantly lower mean daily ICS dose with Symbicort SMART compared with high-dose Seretide plus SABA (2000 µg compared with 1238 µg BDP-equivalent, respectively) (p<0.0001).2 The number of days with oral steroid use due to severe exacerbations were reduced with Symbicort SMART compared with the other treatment groups in both studies.1,2 In Kuna et al, the oral steroid days were 619 for Symbicort SMART, 1044 for Symbicort+SABA and 1132 for Seretide+SABA. In Bousquet et al, the oral steroid days were 764 for Symbicort SMART and 990 for high dose Seretide+SABA. In the study by Kuna et al. patients with symptomatic asthma (n=3335) were randomised to 6 months of treatment with either Symbicort SMART (160/4.5 µg bid+as needed), fixed-dose Seretide™ (50/250 µg bid) or fixed-dose Symbicort® (320/9 µg bid), both plus SABA as needed.1 In the study by Bousquet et al. patients with symptomatic asthma (n=2309) were randomised to 6 months of treatment with either Symbicort SMART (2 x 160/4.5 µg bid+as needed) or high-dose Seretide (50/500 µg bid) plus SABA as needed.2 1.
