Abstract

Clozapine is one of the second generation antipsychotics most commonly associated with serious metabolic side effects including weight gain. Unexpectedly, weight loss can also be seen as a rare side effect of clozapine. The mechanism underlying clozapine induced weight loss is not clearly understood. Several factors including certain brain areas, neurotransmitters, neuropeptides and genetic variants were identified to play a role in weight loss associated with clozapine. In some patients who were reported to have a significant weight loss (13.5-50% of body weight) with clozapine, weight loss might not be associated with any underlying physical disorder. Weight loss may be due to the patients’ engagement in diet and exercise after clinical improvement, pharmacodynamic effects of clozapine, or other medical problems such as gastrointestinal tract hypomotility caused by clozapine. Some case reports suggested that clozapine-associated weight loss might be a sign of poor response to clozapine. Clinicians should keep in mind the fact that a specific group of patients may lose weight during clozapine treatment. In this case report, possible causes of weight loss due to clozapine use is discussed. We also discussed the possible relationship between clozapine dose and weight loss which has not drawn attention in previous case reports.

Özet

Klozapin, kilo artışı gibi metabolik yan etkilere en çok yol açan ikinci kuşak antipsikotiklerden biridir. Ancak, çok seyrek olmakla birlikte bazı hastalarda klozapin kullanımına bağlı kilo kaybı gelişmektedir. Klozapine bağlı kilo kaybının mekanizması henüz anlaşılamamıştır. Birçok beyin bölgesi, nörotransmitter, nöropeptit ve genetik faktörün kilo kaybında rol oynadığı düşünülmektedir. Klozapin kullanımı ile belirgin kilo kaybı (vücut ağırlığının %13,5-50’si) bildirilen vakalarda kilo kaybını açıklayacak herhangi bir bedensel hastalık bulunamamıştır. Bu durum ruhsal rahatsızlık belirtileri azalan hastaların daha çok egzersiz ve perhiz yapmasına bağlı olabileceği gibi tek başına klozapin kullanımının etkisi ile veya klozapinin mide bağırsak hareketlerini yavaşlatmasına ikincil olarak da ortaya çıkabilir. Ayrıca klozapin tedavisi sırasında meydana gelen kilo kaybının klozapine kötü yanıtın bir işareti olabileceğini ileri süren vaka bildirimleri bulunmaktadır. Klinisyenler klozapin kullanan hastaların bir bölümünün kilo verdiğini akılda tutmalıdır. Bu vaka sunumunda klozapin ile tedavi edilen bir şizofreni hastasında kilo kaybının olası nedenleri ve literatürde daha önce bildirilen vakalardan farklı olarak kilo kaybı ile klozapin dozu arasındaki olası ilişki tartışılmıştır.
