Gastrointestinal Sistem Ağrılarında Mikrobiyal Etkenler; Patogenezden Kliniğe
Özet
Gastrointestinal sistem ağrısı, klinik uygulamada en sık karşılaşılan semptomlardan biri olup enfeksiyöz ve enfeksiyöz olmayan çok sayıda hastalığın ortak bulgusudur. Mikrobiyal etkenler, akut ve kronik gastrointestinal ağrının önemli nedenleri arasında yer almakta; bakteriler, virüsler, parazitler ve mantarlar farklı patojenik mekanizmalar aracılığıyla ağrı gelişimine katkıda bulunmaktadır. Bu bölümde gastrointestinal sistem ağrısına neden olan başlıca mikrobiyal etkenler güncel literatür doğrultusunda değerlendirilmiş; ağrının oluşumunda rol oynayan mukozal invazyon, toksin üretimi, inflamasyon, visseral hipersensitivite, nöroimmün etkileşimler ve mikrobiyota–bağırsak–beyin ekseni ayrıntılı olarak ele alınmıştır. Ayrıca Helicobacter pylori, Salmonella spp., Shigella spp., Campylobacter spp., patojenik Escherichia coli grupları, viral gastroenterit etkenleri, intestinal parazitler ve fırsatçı fungal enfeksiyonların gastrointestinal ağrıdaki klinik önemi özetlenmiştir. Son yıllarda moleküler tanı yöntemleri, mikrobiyota analizleri ve nörogastroenteroloji alanındaki gelişmeler, gastrointestinal ağrının patogenezinin daha iyi anlaşılmasını sağlamış ve hedefe yönelik yeni tedavi yaklaşımlarına ışık tutmuştur. Mikrobiyal etkenlerin doğru tanımlanması ve patofizyolojik mekanizmaların anlaşılması, gastrointestinal ağrının etkili tanı ve tedavisinde temel öneme sahiptir.
Gastrointestinal pain is one of the most common symptoms encountered in clinical practice and represents a shared manifestation of numerous infectious and non-infectious diseases. Microbial pathogens constitute major causes of both acute and chronic gastrointestinal pain, with bacteria, viruses, parasites, and fungi contributing through diverse pathogenic mechanisms. This chapter comprehensively reviews the principal microbial agents associated with gastrointestinal pain and discusses the underlying mechanisms, including mucosal invasion, toxin production, inflammation, visceral hypersensitivity, neuroimmune interactions, and the microbiota–gut–brain axis. The clinical significance of Helicobacter pylori, Salmonella spp., Shigella spp., Campylobacter spp., pathogenic Escherichia coli strains, viral gastroenteritis agents, intestinal parasites, and opportunistic fungal infections is also summarized. Recent advances in molecular diagnostics, microbiome research, and neurogastroenterology have significantly improved our understanding of the pathogenesis of gastrointestinal pain and have opened new perspectives for targeted therapeutic strategies. Accurate identification of microbial pathogens together with a comprehensive understanding of the underlying pathophysiological mechanisms is essential for improving the diagnosis, management, and prevention of gastrointestinal pain associated with infectious diseases.
