Regular and continuous screening of anti-TB drug resistance should be accomplished to survey the presence of drug resistant strains in the nation, to define the suitable drug regimens and to evaluate the quality of tuberculosis control programs.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:In this retrospective study, it was aimed to evaluate the primary drug resistance rates of 151 Mycobacterium tuberculosis complex (MTC) strains against primary anti-tuberculosis (anti-TB) drugs, isolated from 2213 tuberculosis suspected patients between January 2002 to December 2003 in our hospital, and also to compare these results with the data obtained from our previous results between January 1998 to December 2001.
📊
Key Findings & Data:It has been detected that there was a significant decrease in the susceptibility rates of MTC isolates to all anti-TB drugs both yearly from 1998 to 2003 (p< 0.001), and for the total of 1998 and 2003 years period (p<0.029).
💡
Conclusion & Impact:Regular and continuous screening of anti-TB drug resistance should be accomplished to survey the presence of drug resistant strains in the nation, to define the suitable drug regimens and to evaluate the quality of tuberculosis control programs.

Abstract

In this retrospective study, it was aimed to evaluate the primary drug resistance rates of 151 Mycobacterium tuberculosis complex (MTC) strains against primary anti-tuberculosis (anti-TB) drugs, isolated from 2213 tuberculosis suspected patients between January 2002 to December 2003 in our hospital, and also to compare these results with the data obtained from our previous results between January 1998 to December 2001. It has been detected that there was a significant decrease in the susceptibility rates of MTC isolates to all anti-TB drugs both yearly from 1998 to 2003 (p< 0.001), and for the total of 1998 and 2003 years period (p<0.029). When only the years 1998 and 2003 were taken into consideration, significant increases were found in any (one or more) combination of the drugs,.with isoniazid (INH), and only INH resistance rates (p<0.007 and p<0.033, respectively). Thus, naturally there was also an increase in resistance to total any drug resistance (p<0.029). We suggest that strict measures such as "directly observed therapy" should be undertaken in order to prevent development of drug resistance particularly against INH. Regular and continuous screening of anti-TB drug resistance should be accomplished to survey the presence of drug resistant strains in the nation, to define the suitable drug regimens and to evaluate the quality of tuberculosis control programs.

Özet

Bu retrospektif çalışmada, hastanemizde Ocak 2002-Aralık 2003 tarihleri arasında tüberküloz (TB) şüpheli 2213 hastanın 151'inden izole edilen Mycobacterium tuberculosis kompleks (MTK) suşlarının, ilk kuşak antitüberküloz (anti-TB) ilaçlara karşı primer ilaç direnç oranlarının saptanması ve Ocak 1998-Aralık 2001 tarihleri arasında elde edilen verilerle karşılaştırılması amaçlanmıştır. Hem 1998 yılından 2003 yılına kadar geçen sürede her yıl (p<0.001), hem de sadece 1998 ile 2003 yılları (p<0.029) dikkate alındığında, anti-TB ilaçların tümüne karşı duyarlılık oranlarında anlamlı bir azalmanın olduğu izlenmiştir. Sadece 1998 ile 2003 yılları esas alındığında, gerek tek başına izoniazide (INH) direnç oranlarında (p<0.033), gerekse INH ile herhangi bir ilacın kombinasyonuna karşı direnç oranlarında (p<0.007) anlamlı bir artışın olduğu ve bu artışın, toplam herhangi bir ilaca (tek veya kombine) direnç oranına da yansıdığı (p<0.029) görülmüştür. Özellikle son yıllarda INH'e karşı direnç oranlarının artış göstermesi, anti-TB ilaçlara direncin kontrol edilmesinde "direk gözetim altında tedavi yöntemi" gibi katı önlemlerin uygulanmasını gerekli kılmaktadır. Toplumdaki ilaca dirençli suşların yayılımlarını ortaya koymak, uygun ilaç rejimlerini belirlemek ve TB kontrol programlarının kalitesini değerlendirebilmek için anti-TB ilaç direnç taramaları, düzenli ve sürekli olarak yapılmalıdır.
