Prevalența PID-BTC

Fibroza pulmonară este o amenințare critică într-o gamă largă de pneumopatii interstițiale difuze asociate cu boala țesutului conjunctiv (PID-BTC)1–5

Clepsidra

PNEUMOPATIA INTERSTIȚIALĂ DIFUZĂ (PID) ESTE O MANIFESTARE TIMPURIE COMUNĂ A BTC ȘI ARE CĂI PATOGENICE COMUNE CĂTRE FIBROZA1–7

PID alcătuiește un grup divers de peste 200 de afecțiuni pulmonare heterogene, în mare parte clasificate ca fiind rare sau observate doar rar în practica clinică8–10

În timp ce unele PID sunt idiopatice, altele se manifestă ca rezultat al expunerii la antigenele de mediu sau ca o complicație pulmonară a unui BTC subiacent11

În PID-BTC, fibroza pulmonară este caracterizată prin cicatrizarea adesea cronică și ireversibilă a țesutului pulmonar,12,13 și este un factor cheie al leziunilor pulmonare ireversibile și al mortalității precoce în BTC.1–5,14

Care este prevalența PID în BTC?

Estimările de prevalență pentru diferite BTC și PID-BTC variază între diferite studii. Cifrele de prevalență prezentate mai jos se bazează pe o serie de estimări diferite din diverse studii.15–40

Cifrele de prevalență sunt obținute ca valori medii din intervalele pentru prevalența BTC și PID-BTC, după cum urmează: Prevalența AR 500-1000 la 100 000;15–17 Prevalența PID-AR 10%-30% din AR.18-22 Prevalența ScS 7,2-44,3 la 100 00023 Prevalența PID-ScS 42% din ScS.24 Prevalența sindromului Sjögren primar 90-2700 la 100 00025,26 Sindromul Sjögren primar-Prevalența PID 8%-20% din sindromul Sjögren primar27-30 Prevalența PM/DM 5-22 la 100 00031,32 Prevalența PM/DM/CADM-ILD 20%-78% din PM/DM/CADM.33-40

DE CE ESTE IMPORTANT DIAGNOSTICUL PRECOCE AL PID?

PID se dezvoltă adesea devreme în cursul evoluției BTC și poate fi chiar prima manifestare a unei BTC nediagnosticată sau nerecunoscută anterior,1,2,5,6 PID în BTC poate fi de natură subclinică (fără simptome),7 poate fi cronic progresivă, sau chiar prezentă într-o manieră care pune viața în pericol.42

Exacerbarea acută a PID, caracterizată prin deteriorarea rapidă a respirației cu hipoxemie severă, poate apărea la pacienții cu PID-BTC în orice moment pe parcursul evoluției bolii.43–47 Pe baza pacienților cu FPI, exacerbarea acută a PID este cel mai probabil declanșată de un eveniment acut, cum ar fi infecția.48 Se raportează că mortalitatea spitalicească post-exacerbare la pacienții cu PID-BTC variază între 50%-100%.43
