Summary: | The objective of this prospective, multicenter, observational study was to evaluate healthcare for hepatitis C virus (HCV)-infected drug abusers in France and to determine predictors of successful therapeutic intervention. A total of 170 drug users were recruited from 40 French centers. Three centers recruited 66 participants (38.8%), and one to eight patients each were enrolled from 37 other centers (
n
=
104). A sustained viral response (SVR) was seen in 65 (38.2%) patients. SVR rates were significantly higher in compliant than in non-compliant patients (43.5% versus 23.9%;
P
=
0.019), in patients from high- rather than low-recruiting centers (54.5% versus 27.9%;
P
<
0.001) and in patients receiving Buprenorphine
® rather than methadone (48.1% versus 21.8%;
P
=
0.001). In patients, who completed both the treatment and follow-up (
n
=
94), SVR rate was 57.4%. Buprenorphine
® substitution therapy and genotypes 2 or 3 HCV infection were associated with significantly higher rates of SVR (
P
<
0.01, for both comparisons). In conclusion, successful care of hepatitis requires an active treatment policy of every center toward drug addicts. Additional studies are needed to explore the difference in SVR with methadone versus Buprenorphine
® therapy.
Cette étude multicentrique, observationnelle, prospective avait pour but d’étudier l’accès aux soins et le résultat du traitement des hépatites C des usagers de drogue recevant un traitement de substitution en France. Cent soixante-dix usagers de drogue ont été recrutés dans 40 centres (70 centres prévus) sur les 400 initialement attendus. Trois centres ont inclus 66 malades (38,8 %). Les 37 autres ont enrôlé un à huit patients chacun (
n
=
108). Une réponse virologique prolongée a été observée dans 65 cas. Les réponses virologiques prolongées étaient plus fréquentes chez les malades
compliants (43,5 % versus 23,9 % ;
p
=
0,019), chez les malades des centres à fort recrutement (54,5 % versus 27,9 % ;
p
<
0,001), et chez les patients traités par la Buprénorphine
® comparés à ceux recevant de la méthadone (48,1 % versus 21,8 % ;
p
=
0,001). Chez les patients qui ont terminé leur traitement et qui ont eu un suivi complet, une réponse virologique prolongée a été observée dans 57,4 % des cas. La prise de buprénoprhine et les génotypes 2 ou 3 étaient associés à la réponse virologique prolongée (
p
<
0,001 pour chacun). En conclusion, réussir à traiter des usagers de drogue suppose une politique active de chaque centre. Les d |
