Item Current therapeutic approaches in childhood chronic hepatitis B infection: A multicenter study(Wiley, 2004-02) Dikici, Bünyamin; Özgenç, Funda; Kalaycı, Ayhan Gazi; Targan, Şeref; Seli̇moğlu, Ayşe; Doğancı, Tümay; Kansu, Aydan; Tosun, Selma Yegane; Arslan, Nur Ç.; Kasırga, Erhun; Boşnak, Mehmet; Özkan, Tanju Başarır; Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0001-5740-9729; 7004474005Background and Aim: The aim of the present study was to compare the therapeutic efficacy of three different regimens in childhood chronic hepatitis B (CHB) infection. Methods: A total of 182 children with CHB infection were prospectively allocated to three random groups. Sixty-two patients in the first group received high-dose interferon (IFN)-alpha 2b (10 MU/m(2)) thrice/weekly alone for 6 months. In the second (n = 60) and third groups (n = 60), IFN-alpha was used for 6 months (5 MU/m(2)) thrice/weekly in combination with lamivudine (LAM) (4 mg/kg, maximum 100 mg/day) for 12 months. Lamivudine was started simultaneously with IFN in the second group, while it was started 2 months prior to IFN injections in the third group. Results: The initial mean alanine aminotransferase (ALT) values for the first, second and third groups were 109 +/- 93 IU/L, 101 +/- 64 IU/L and 92 +/- 42 IU/L, respectively (P > 0.05). At the end of the therapy, ALT values decreased to 82 +/- 111 IU/L, 38 +/- 41 IU/L and 29 +/- 16 IU/L in groups 1, 2 and 3, respectively. The mean ALT value of the first group was significantly different to the second and third groups (P = 0.046 and P = 0.002, respectively) at the end of the therapy and these differences were found to be sustained after 18 months. However, results in the second and third groups were similar (P > 0.05). There were no significant differences in HBeAg clearance and anti-HBe seroconversion at the initial stage, 12 months and 18 months between the three groups (P > 0.05). Hepatitis B virus (HBV) DNA clearance in the first group was different from the second and third groups, while the second and third groups had similar HBV DNA clearance ratios at 12 and 18 months. No significant difference was found in the complete response (normalization of ALT, clearance of HBV DNA and seroconversion of anti HBe) ratios of all groups (at 12 months: 28.8, 45.5, 35.8% and at 18 months 33.3, 49 and 34% in groups 1, 2 and 3, respectively, P > 0.05). Conclusions: Although the ALT normalization and HBV DNA clearance ratios of IFN plus LAM combination groups were better than the high-dose IFN-alpha monotherapy group, no significant difference was found in the complete response ratios of all three groups.Publication Familial mediterranean fever mutation analysis in pediatric patients with inflammatory bowel disease: A multicenter study(Aves, 2021-03-01) Urgancı, Nafiye; Özgenç, Funda; Kuloğlu, Zarife; Yüksekkaya, Hasan; Sarı, Sinan; Erkan, Tülay; Önal, Zerrin; Caltepe, Gönul; Akçam, Mustafa; Arslan, Duran; Arslan, Nur; Artan, Reha; Aydoğan, Aysen; Balamtekin, Necati; Baran, Masallah; Baysoy, Gökhan; Çakır, Murat; Dalgıç, Buket; Doğan, Yaşar; Durmaz, Özlem; Ecevit, Çiğdem; Eren, Makbule; Gökçe, Selim; Gülerman, Fulya; Gürakan, Figen; Hızlı, Şamil; Işık, İshak; Kalaycı, Ayhan Gazi; Kansu, Aydan; Kutlu, Tufan; Karabiber, Hamza; Kasırga, Erhun; Kutluk, Günsel; Hoşnut, Ferdağ Özbay; Özen, Hasan; Özkan, Tanju; Öztuürk, Yeiim; Soylu, Özlem Bekem; Tutar, Engin; Tumgör, Gökhan; Unal, Fatih; Uğraş, Meltem; Üstündağ, Gonca; Yaman, Aytaç; ÖZKAN, TANJU MUNEVVER; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Çocuk Gastroenteroloji Anabilim Dalı.; JGY-1667-2023Background: the aim of the study was to evaluate familial Mediterranean fever (FMF) mutation analysis in pediatric patients with inflammatory bowel disease (IBD). The relation between MEFV mutations and chronic inflammatory diseases hos been reported previously.Methods: Children with IBD (334 ulcerative colitis (UC), 224 Crohn's disease (CD), 39 indeterminate colitis (IC)) were tested for FMF mutations in this multicenter study. The distribution of mutations according to disease type, histopathological findings, and disease activity indexes was determined.Results: A total of 597 children (mean age: 10.8 +/- 4.6 years, M/F: 1.05) with IBD were included in the study. In this study, 41.9% of the patients had FMF mutations. E148Q was the most common mutation in UC and CD, and M694V in IC (30.5%, 34.5%, 47.1%, respectively). There was a significant difference in terms of endoscopic and histopathological findings according to mutation types (homozygous/heterozygous) in patients with UC (P <.05).There was a statistically significant difference between colonoscopy findings in patients with or without mutations (P=.031, P=.045, respectively). The patients with UC who had mutations had lower Pediatric Ulcerative Colitis Activity Index (PUCAI) scores than the patients without mutations (P=.007).Conclusion: Although FMF mutations are unrelated to CD patients, but observed in UC patients with low PUCAI scores, it was established that mutations do not hove a high impact on inflammatory response and clinical outcome of the disease.Publication The frequency of lysosomal acid lipase deficiency in children with unexplained liver disease(Lippincott, 2019-03-01) Kuloğlu, Zarife; Kansu, Aydan; Selbuz, Suna; Kalaycı, Ayhan G.; Şahin, Gülseren; Kırsaçlıoğlu, Ceyda Tuna; Demirören, Kaan; Dalgıç, Büket; Kasırga, Erhun; Önal, Zerrin; İslek, Ali; Eren, Esra; Hoşnut, Ferda Özbay; Urgancı, Nafiye; Yaman, Aytaç; Özkan, Tanju; Bozbulut, Ekşi; Doğan, Güzide; Ekşi Bozbulut, Neslihan; Doğan, Güzide; Durmaz Uğurcan, Özlem; Usta, Ayşe Merve; Arslan, Duran; Akçam, Mustafa; Isik, Ishak Abdurrahman; Ecevit, Çigdem Ömür; Usta, Yusuf; Özgür, Taner; Özçay, Figen; Balamtekin, Necati; Öztürk, Yesim; Balamtekin, Necati; Öztürk, Yeşim; Cantez, Serdar; Gülerman, Fulya; Ustundag, Gonca Handan; Emiroğlu, Halil Haldun; Karacabey, Neslihan; Comba, Atakan; Erdemir, Gülin; Aydoğan, Aysen Uncuoğlu; Gökçe, Selim; Kuyum, Pınar; Gülsan, Meltem; Tosun, Mahya Sultan; Tokgöz, Yavuz; Güven, Burcu; Yüksekkaya, Hasan; Tümgör, Gökhan; Eren, Makbule; Baran, Maşallah; Gümüş, Meltem; Canan, Oğuz; Kocamaz, Halil; Gerenli, Nelgin; Çakır, Murat; Agiı, Mehmet; Hızlı, Samil; Doğan, Yasar; Çeltik, Coşkun; Deveci, Uğur; Balcı Sezer, Oya; Natl Lal-D Study Grp; ÖZKAN, TANJU MUNEVVER; ÖZGÜR, TANER; Bursa Uludağ Üniversitesi/Tıp Fakültesi; AAG-8416-2021; AAG-8381-2021Objectives: Evidence suggests that lysosomal acid lipase deficiency (LAL-D) is often underdiagnosed because symptoms may be nonspecific. We aimed to investigate the prevalence of LAL-D in children with unexplained liver disease and to identify demographic and clinical features with a prospective, multicenter, cross-sectional study.Methods: Patients (aged 3 months-18 years) who had unexplained transaminase elevation, unexplained hepatomegaly or hepatosplenomegaly, obesity-unrelated liver steatosis, biopsy-proven cryptogenic fibrosis and cirrhosis, or liver transplantation for cryptogenic cirrhosis were enrolled. A Web-based electronic data collection system was used. LAL activity (nmol/punch/h) was measured using the dried blood spot method and classified as LAL-D(<0.02), intermediate (0.02-0.37) or normal (>0.37). Asecond dried blood spot sample was obtained from patients with intermediate LAL activity for confirmation of the result.Results: A total of 810 children (median age 5.6 years) from 795 families were enrolled. The reasons for enrollment were unexplained transaminase elevation (62%), unexplained organomegaly (45%), obesity-unrelated liver steatosis (26%), cryptogenic fibrosis and cirrhosis (6%), and liver transplantation for cryptogenic cirrhosis (<1%). LAL activity was normal in 634 (78%) and intermediate in 174 (21%) patients. LAL-D was identified in 2 siblings aged 15 and 6 years born to unrelated parents. Dyslipidemia, liver steatosis, and mild increase in aminotransferases were common features in these patients. Moreover, the 15-year-old patient showed growth failure and microvesicular steatosis, portal inflammation, and bridging fibrosis in the liver biopsy. Based on 795 families, 2 siblings in the same family were identified as LAL-D cases, making the prevalence of LAL-D in this study population, 0.1% (0.125%-0.606%). In the repeated measurement (76/174), LAL activity remained at the intermediate level in 38 patients.Conclusions: Overall, the frequency of LAL-D patients in this study (0.1%) suggests that LAL-D seems to be rare even in the selected high-risk population.
