INTRODUCTION: Personalized management strategies are pivotal in addressing irritable bowel syndrome (IBS). This multicenter randomized controlled trial focuses on comparing the efficacy of a microbiome-based artificial intelligence-assisted personalized diet (PD) with low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) for IBS management. METHODS: One hundred twenty-one patients participated, 70 assigned to PD group 51 FODMAP group. subtypes, demographics,...

İnsanlığın karşı karşıya kaldığı en önemli halk sağlığı sorunlarından biri olan ilaç direnci, antilayşmanyal ajan geliştirmede yeni stratejileri ve yaklaşımları zorunlu kılmaktadır. Dışa atım pompa inhibitörleri (DAPİ) diğer aday ajanlar ile ilgili gelişmeler umut verici olmakla birlikte, mevcut antilayşmanyallerin kullanım sürelerini etkinliklerini artırabilme arayışları da devam etmektedir. Bu çalışmada rezerpin (REZ), berberin (BER) verapamil (VER) olmak üzere üç adet DAPİ'nin...

Leishmania infantum is widely recognized as the primary causative agent of visceral leishmaniasis (VL) in Turkey, while tropica predominantly causes cutaneous (CL). Although L. capable causing VL, such cases remain exceedingly rare. This study aimed to identify genetic factors underlying visceralization potential by comparing isolates from VL and CL patients. Fourteen patients diagnosed with infection, confirmed parasite detection genotyping between 2012 2022, were included: seven CL....

Parasites might cause atypical and severe infections in immunocompromised hosts. The prevalence of diarrhea among common variable immune deficiency (CVID) syndrome patients varies between 20% 94%, which indicates that gastrointestinal system (GIS) complaints could be the second leading morbidity CVID after respiratory tract infections. This study aimed to assess intestinal parasites with GIS diarrhea.In this study, all cases followed up Immunology Allergy Clinic Ege University School...

Background: Currently, medications and behavioral modifications have limited success in the treatment of functional constipation (FC). An individualized diet based on microbiome analysis may improve symptoms FC. In present study, we aimed to investigate impacts modulation chronic constipation. Methods: Between December 2020−December 2021, 50 patients fulfilling Rome IV criteria for were randomized into two groups. The control group received sodium picosulfate plus conventional treatments...

The most common types of malaria in the world are Plasmodium vivax and P. falciparum. In countries where both species endemic, falciparum coinfection also occurs. Thus, possibility mixed Turkey should always be considered cases with a traveling history to these countries. Here, we report case vivax/P. infection that was diagnosed as Ethiopia. However, administered treatment inadequate, recurred because miss diagnosis malaria, for which an effective drug hypnozoites not administered. This...

Objective: Visceral Leishmaniasis (VL) is a widespread infectious disease of the reticuloendothelial system which mostly caused by Leishmania infantum and L.donovani. VL zoonotic infection dogs act as main reservoirs while vectors are female Phlebotomus, that to say, sandflies. Although spp. attributed reproduce asexually, genetic exchange between different strains has recently been demonstrated causes interspecific hybrids. We aimed present complete cycle hybrid strain infantum/donovani...
