Obsesif kompulsif bozuklukta tedaviye cevapla ilişkili etkenler

Amaç: Bu çalışmada obsesif kompulsif bozuklukta (OKB) farmakolojik tedaviye yanıta etki eden faktörlerin araştırılması amaçlanmıştır, yöntem: Çalışmaya USM-IVe göre OKB tanısı konmuş olan 60 hasta (39 kadın ve 21 erkek) alınmıştır. Tüm hastalara, Yale-Brown Obsesyon Kompulsiyon Ölçeği (V-BOCS) uygulanmıştır Klinik değerlendirme sonrasında hastalara ilaç tedavisi başlandı (28 hastaya fluvoksamin 1OO-300 mg/gün; 15 hastaya fluoksetin 20-80 mg/gün ve 17 hastaya sertralin 100-200 mg/gün). Tedavi dozları hastanın klinik durumuna ve yan etkilere göre ayarlandı. Tedaviye, yanıt üçüncü ayın sonunda Klinik Global izlenim Ölçeği (KGl) ile değerlendirildi. Çok daha iyi ve daha iyi olanlar cevap verenler olarak tanımlandı. Tedavi yanıtına etki eden faktörleri saptamak için lojistik regresyon analizi uygulandı. Sonuçlar: Lojistik regresyon analizi sonucunda yaş, cinsiyet, hastalığın başlama yaşı, hastalık süresi, eşlik eden tik bozukluğu, Y-BOCS obsesyon, kompulsiyon, içgörü ve ciddiyet puanları değişkenleri arasında sadece içgörü puanının tedavi yanıtı üzerinde etkili olduğu bulundu (p=0.038, %95 CI 0.225-0.957). Buna göre içgörü puanının l puan düşük olması tedaviye yanıt verme olasılığını 2.5 kat artırıyordu. Tartışma: OKB'de tedaviye cevap ile ilişkili etkenler ile ilgili çalışmaların sonuçları yeterince net değildir. Obsesif kompulsif bozuklukta tedavi başarısı ya da başarısızlığı ile ilişkili prognostik değişkenlerin doğru şekilde tanımlanması tedavi programlarının gözden geçirilerek hastalara özgü farklı tedavi stratejilerinin uygulanmasına yol açabilecektir.

Factors associated with treatment response in obsessive compulsive disorder

Objective: The objective of this study was to investigate potential factors that might influence response to pharmacological treatment in obsessive compulsive disorder (OCD). Methods: A total of 60 patients with OCb diagnosed according to USM-IV criteria (39 women and 21 men) were included in the study. All patients were administered Yale-Brown Obsessive Compulsive Scale (Y-BOCS). After clinical evaluation, the patients were started on pharmacotherapy (28 patients on fluvoxamine 100-300 mg/day; 15 patients on fluoxetine 20-80 mg/day and 17patients on sertraline 100-200 mg/day) and dosages were adjusted according to clinical condition of the patients and adverse effects. Response to treatment was evaluated with Clinical Global Impression Scale (CGI) at the end of 3rd month of treatment. Responders were defined as those rated improved or very much improved on CGI. Results: A logistic regression analysis was done to investigate factors that might influence treatment response. Age, sex, age at onset, duration of disorder, accompanying tic disorder and obsession, compulsion, insight and severity scores on Y-BOCS were entered into logistic regressionanalysis, which revealed that among these variables, only insight score had influence on treatment response (p-0.038, %95 CI 0.225-0.957). Every one-point decrease in insight score increased the likelihood of treatment response 2.5 fold. discussion: Results of studies about factors associated with treatment response are not conclusive. Identification of prognostic factors associated with treatment success in OCd would lead to revision of treatment programs, resulting in administration of patient-specific treatment strategies.
