Noninvasive Models to Predict Liver Fibrosis in Patients with Chronic Hepatitis B: A Study from Turkey
Background: Many noninvasive methods, including aspartate amino transaminase (AST)/alanine 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 was 40.60 ± 12.34 years (minimum, 18 years; maximum, 77 years). The Ishak fibrosis score was ≥ 3 in 29.8% of the patients, indicating significant fibrosis. The mean API, APRI, CDS, NLR, FIB4, and RPR scores in the noninvasive models were significantly different between the groups with significant and low fibrosis (P < 0.05). All the noninvasive models (API, APRI, AAR, CDS, NLR, RPR, and FIB4) were found to be significant in the discrimination of cirrhosis (P < 0.05). In the multiple logistic regression analysis, CDS, albumin, alkaline phosphatase (ALP), total bilirubin, neutrophil count, NLR, mean platelet volume (MPV), and FIB4 were independent indices for cirrhosis. Conclusions: In the present study, the role of noninvasive tests in the prediction of liver fibrosis stage and cirrhosis was evaluated in a large cohort of CHB patients. Overall, noninvasive models are gradually becoming more promising. Accordingly, the need for liver biopsy can be reduced with a combination of noninvasive methods in the future.
A novel id-iri score: development and internal validation of the multivariable community acquired sepsis clinical risk prediction model
We aimed to develop a scoring system for predicting in-hospital mortality of community-acquired (CA) sepsis patients. This was a prospective, observational multicenter study performed to analyze CA sepsis among adult patients through ID-IRI (Infectious Diseases International Research Initiative) at 32 centers in 10 countries between December 1, 2015, and May 15, 2016. After baseline evaluation, we used univariate analysis at the second and logistic regression analysis at the third phase. In this prospective observational study, data of 373 cases with CA sepsis or septic shock were submitted from 32 referral centers in 10 countries. The median age was 68 (51–77) years, and 174 (46,6%) of the patients were females. The median hospitalization time of the patients was 15 (10–21) days. Overall mortality rate due to CA sepsis was 17.7% (n = 66). The possible predictors which have strong correlation and the variables that cause collinearity are acute oliguria, altered consciousness, persistent hypotension, fever, serum creatinine, age, and serum total protein. CAS (%) is a new scoring system and works in accordance with the parameters in third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). The system has yielded successful results in terms of predicting mortality in CA sepsis patients.
İmmünosüpresif Tedavi Veren Hekimlerin Hepatit B Virusu Reaktivasyonuyla İlgili Farkındalıklarının ve Klinik Pratiklerinin Değerlendirilmesi
Amaç: Bu çalışmada, immünosüpresif tedavi veren tüm hekimlerin hepatit B virusu (HBV) reaktivasyonuyla ilgili farkındalığının ve bilgi düzeyinin değerlendirilmesi; bu değerlendirme aracılığıyla da konunun önemine dikkat çekilmesi amaçlanmıştır. Yöntemler: Çalışma Ocak-Mart 2017 tarihleri arasında, Türkiye'de 37 sağlık kuruluşunda infeksiyon hastalıkları ve klinik mikrobiyoloji uzmanı hekimler tarafından yürütüldü. Çalışmaya her merkezde Tıbbi Onkoloji, Hematoloji, Deri ve Zührevi Hastalıklar, Fiziksel Tıp ve Rehabilitasyon ve Romatoloji birimlerinde görev yapan ve yazılı onamı alınan tüm uzman hekimler dahil edildi. Bulgular: Araştırmaya toplam 430 hekim katıldı. Hekimlerin yaş ortalaması 39.87±7.42 olup %47.9’unu erkekler oluşturuyordu. Hekimlerin çalışma yılı ortalaması 9.26±7.56 yıldı. Ankete katılan hekimlerin %39.3’ü çalıştıkları süre boyunca immünosüpresif tedavi alırken HBV reaktivasyonu gelişen hastayla karşılaşmışlardı. HBV reaktivasyonu sonucu ölüm gelişen hastayla karşılaşma oranı %6.5 idi. Ankete katılan hekimlerin %97’si HBV reaktivasyonu riskini önemli görmekteydi. Hekimlerin %70.2’si uzmanlık alanıyla ilgili katıldıkları kongrelerde HBV reaktivasyonuyla ilgili rehberlerin ve bu hastalarda antiviral tedavinin tartışıldığını belirtti. HBV reaktivasyonu gelişen hastaları olan hekimlerin hepatit taraması yapma oranı, HBV reaktivasyonu gelişen hastası olmayan hekimlerden istatistiksel olarak anlamlı bir biçimde yüksekti (p<0.05). HBV reaktivasyonuyla ilgili uzmanlık alanına ait rehberleri kullanan hekimlerin bu rehberleri kullanmayan hekimlere göre HBV infeksiyonu yönünden daha fazla tarama yaptığı görüldü (p=0.002). Sonuçlar: Çalışmamızda elde edilen sonuçlara göre, immünosüpresif tedavi veren hekimlerin HBV infeksiyonu yönünden tarama yapma oranları ve farkındalıkları benzer çalışmalara göre daha yüksektir. Bununla birlikte HBV infeksiyonu yönünden taramada kullandıkları serolojik göstergeler arasında HBV DNA ve anti-HBc’nin araştırılmasına daha fazla yer vermeleri için farkındalıklarının artırılması gerekmektedir.
