Brucellosis is a zoonotic disease that primarily affects the reticuloendothelial system. But, the extent of liver damage in due course of the disease is unclear. This study included 325 brucellosis patients with significant hepatobiliary involvement identified with microbiological analyses from 30 centers between 2000 and 2013. The patients with ≥5 times of the upper limit of normal for aminotransferases, total bilirubin level ≥2 mg/dl or local liver lesions were enrolled. Clinical hepatitis was detected in 284 patients (87.3 %) and cholestasis was detected in 215 (66.1 %) patients. Fatigue (91 %), fever (86 %), sweating (83 %), arthralgia (79 %), and lack of appetite (79 %) were the major symptoms. Laboratory tests showed anemia in 169 (52 %), thrombocytopenia in 117 (36 %), leukopenia in 81 (25 %), pancytopenia in 42 (13 %), and leukocytosis in 20 (6 %) patients. The most commonly used antibiotic combinations were doxycycline plus an aminoglycoside (n = 73), doxycycline plus rifampicin (n = 71), doxycycline plus rifampicin and an aminoglycoside (n = 27). The duration of ALT normalization differed significantly in three treatment groups (p < 0.001). The use of doxycycline and an aminoglycoside in clinical hepatitis showed better results compared to doxycycline and rifampicin or rifampicin, aminoglycoside, doxycycline regimens (p < 0.05). However, the length of hospital stay did not differ significantly between these three combinations (p > 0.05). During the follow-up, treatment failure occurred in four patients (1 %) and relapse was seen in three patients (0.9 %). Mortality was not observed. Hepatobiliary involvement in brucellosis has a benign course with suitable antibiotics and the use of doxycycline and an aminoglycoside regimen seems a better strategy in select patients.

Two cases of brucellar spondylodiscitis of the lumbar area were presented. Although both cases showed typical radiological changes, serological tests could not detect Brucella agglutinating antibodies. One of the patients was bacteremic and Brucella spp. was identified from blood culture. In the second patient needle biopsy was required for definite diagnosis. Although small, serologic tests have a certain rate of false negative results in brucellosis. Thus, a negative serology should not exclude the diagnosis of brucellosis, as it is demonstrated in the current cases.

Extended spectrum beta-lactamase (ESBL) producing Escherichia coli has been an emerging etiologic agent in the community acquired infections. We investigated the occurrence of ESBL producing E. coli isolated from patients admitted with community acquired urinary tract infection (UTI) to the hospital of the Trakya University, Turkey during 2006. Eleven single patient isolates of E. coli harboring ESBL were identified among 30 E. coli isolated from patients admitted with symptoms corresponding to upper UTI. CTX-M type ESBLs were detected in all 11 ESBL-producers by isoelectric focusing and polymerase chain reaction screening. Sequence analysis revealed CTX-M-1 in one isolate, CTX-M-3 in three isolates and CTX-M-15 in seven isolates. ESBL-producing E. coli isolated from community acquired UTIs are widespread in the European part of Turkey.

Background: Many noninvasive methods, including amino transaminase (AST)/amino transaminase (ALT) ratio (AAR), AST-to-platelet ratio index (APRI), Bonacini cirrhosis discriminant score (CDS), fibrosis-4 (FIB4) index, and age-platelet index (API), have been described to determine the stage of hepatic fibrosis. However, these methods are developed for patients with chronic hepatitis C (CHC) and produce conflicting results in the prediction of liver fibrosis in patients with chronic hepatitis B (CHB). Objectives: The aim of this study was to evaluate the relationship between 7 noninvasive models, including AAR, APRI, CDS, API, FIB-4, neutrophil-to-lymphocyte ratio (NLR), and red cell distribution width (RDW)-to-platelet ratio (RPR) in patients with CHB. Methods: The study population included all patients with CHB, undergoing liver biopsy to determine HBsAg and HBV DNA positivity in more than 6 months. Results: A total of 2520 treatment-naive CHB patients from 40 different centers were included in the study. In total, 62.6% of the patients were male, and the mean age

Background: Chronic hepatitis B (CHB) affects 400 million people worldwide and is a major cause of morbidity and mortality. It is known that HBV DNA sequences were detected after the clearance of serum hepatitis B surface antigen (HBsAg) often in serum, liver and peripheral blood mononuclear cells. The objectives of our study were to evaluate the previous measurements of HBsAg titers versus. quantitative hepatitis B virus (HBV) DNA and ALT measurements in order to predict the nonresponse and response in interferon-alpha (IFN-α)-treated HBeAg-positive and HBeAg-negative chronic HBV patients. Methods: We investigate whether the presence of precore mutant affects the response to IFN-α therapy and on the titer of HBsAg or not. Twenty-one HBeAg-positive (group1), 38 HBeAg-negative (group 2), and 47 healthy inactive carriers (group 3) made up this study. Liver biopsy showed chronic hepatitis, there was no cirrhosis and none of the patients had IFN-α therapy before. Results: The decrease in HBsAg titers was found as statistically not significant in groups 1 (p = 0.192) and 3 (p = 0.236) and statistically significant in group 2 (p = 0.0001) within a 6-month interval. Conclusion: HBsAg titer may be a factor to predict the primary responders and nonresponders specially in HBeAg-negative patients.

Hastaların aynı başvuru sırasında incelenen diğer hepatit B serolojik belirteçleri, HBV-DNA düzeyleri, anti-HCV ve anti-HDV test sonuçları ile karaciğer transaminazları, serum albümin ve bilirubin düzeyleri, trombosit sayısı ve INR değerleri de geriye dönük olarak hastane kayıtlarından incelendi.Bulgular: HBsAg pozitif hastaların %3.6'sında anti-HDV testi pozitif saptandı. Anti-HDV pozitiflik oranının erkek olgularda kadınlardan daha düşük olduğu belirlendi (p=0.009). Yıllara göre anti-HDV pozitiflik oranlarında istatistiksel olarak anlamlı farklılık görülmedi (p>0.05). Anti-HDV negatif olgularda HBV-DNA pozitifliğinin, anti-HDV pozitif hastalardan yüksek olduğu belirlendi (p=0.001). Anti-HDV negatif olgularda anti-HBe pozitiflik oranının, anti-HDV pozitif olgulardan yüksek olduğu saptandı (p=0.001). Delta antikoru saptanan hastalarda trombosit sayısı ve albümin değerlerinin antikor saptanmayan hastalara göre düşük olduğu görülürken, INR değerleri yüksek bulundu (p<0.01). Sonuç: HBsAg pozitif hastalarda %3.6 oranında saptanan anti-HDV pozitifliğinin ülkemizde özellikle batı bölgelerde yapılan çalışmalar ile uyumlu olduğu görülmektedir. Hepatit D enfeksiyonunun klinik seyri göz önüne alındığında, hepatit B enfeksiyonlu hastaların hepatit D açısından taranması ve izlemi bu hastalığın yönetimi açısından oldukça önem taşımaktadır.

Background The core components (CCs) of infection prevention and control (IPC) from World Health Organization (WHO) are crucial for the safety and quality of health care. Our objective was to examine the level of implementation of WHO infection prevention and control core components (IPC CC) in a developing country. We also aimed to evaluate health care-associated infections (HAIs) and antimicrobial resistance (AMR) in intensive care units (ICUs) in association with implemented IPC CCs. Methods Members of the Turkish Infectious Diseases and Clinical Microbiology Specialization Association (EKMUD) were invited to the study via e-mail. Volunteer members of any healt care facilities (HCFs) participated in the study. The investigating doctor of each HCF filled out a questionnaire to collect data on IPC implementations, including the Infection Prevention and Control Assessment Framework (IPCAF) and HAIs/AMR in ICUs in 2021. Results A total of 68 HCFs from seven regions in Türkiye and the Turkish Republic of Northern Cyprus participated while 85% of these were tertiary care hospitals. Fifty (73.5%) HCFs had advanced IPC level, whereas 16 (23.5%) of the 68 hospitals had intermediate IPC levels. The hospitals’ median (IQR) IPCAF score was 668.8 (125.0) points. Workload, staffing and occupancy (CC7; median 70 points) and multimodal strategies (CC5; median 75 points) had the lowest scores. The limited number of nurses were the most important problems. Hospitals with a bed capacity of > 1000 beds had higher rates of HAIs. Certified IPC specialists, frequent feedback, and enough nurses reduced HAIs. The most common HAIs were central line-associated blood stream infections. Most HAIs were caused by gram negative bacteria, which have a high AMR. Conclusions Most HCFs had an advanced level of IPC implementation, for which staffing was an important driver. To further improve care quality and ensure everyone has access to safe care, it is a key element to have enough staff, the availability of certified IPC specialists, and frequent feedback. Although there is a significant decrease in HAI rates compared to previous years, HAI rates are still high and AMR is an important problem. Increasing nurses and reducing workload can prevent HAIs and AMR. Nationwide “Antibiotic Stewardship Programme” should be initiated.
