Five-year follow-up of 96 weeks peginterferon plus tenofovir disoproxil fumarate in hepatitis D.

BACKGROUND & AIMS: Until recently, pegylated interferon-alfa-2a (PEG-IFNa) therapy was the only treatment option for patients infected with hepatitis D virus (HDV). Treatment with PEG-IFNa with or without tenofovir disoproxil fumarate (TDF) for 96 weeks resulted in HDV RNA suppression in 44% of patients at the end of therapy but did not prevent short-term relapses within 24 weeks. The virological and clinical long-term effects after prolonged PEG-IFNa-based treatment of hepatitis D are unknown. METHODS: In the HIDIT-II study patients (including 40% with liver cirrhosis) received 180 µg PEG-IFNa weekly plus 300 mg TDF once daily (n = 59) or 180 µg PEG-IFNa weekly plus placebo (n = 61) for 96 weeks. Patients were followed until week 356 (5 years after end of therapy). RESULTS: Until the end of follow-up, 16 (13%) patients developed liver-related complications (PEG-IFNa + TDF, n = 5 vs PEG-IFNa + placebo, n = 11; p = .179). Achieving HDV suppression at week 96 was associated with decreased long-term risk for the development of hepatocellular carcinoma (p = .04) and hepatic decompensation (p = .009). Including complications irrespective of PEG-IFNa retreatment status, the number of patients developing serious complications was similar with (3/18) and without retreatment with PEG-IFNa (16/102, p > .999) but was associated with a higher chance of HDV-RNA suppression (p = .024, odds ratio 3.9 [1.3-12]). CONCLUSIONS: Liver-related clinical events were infrequent and occurred less frequently in patients with virological responses to PEG-IFNa treatment. PEG-IFNa treatment should be recommended to HDV-infected patients until alternative therapies become available. Retreatment with PEG-IFNa should be considered for patients with inadequate response to the first course of treatment. CLINICAL TRIAL REGISTRATION: NCT00932971.

Development of hepatocellular carcinoma in patients with chronic hepatitis C who had sustained viral response following direct-acting antiviral therapy.

Background and Aim: Several studies have suggested that treatment with direct-acting antivirals (DAAs) in patients with chronic hepatitis C virus (HCV) may be associated with an increased risk of developing hepatocellular carcinoma (HCC). We investigated the incidence and risk factors of HCC in HCV patients who achieved a sustained virologic response (SVR) following DAA therapies. Materials and Methods: The medical data of patients who were diagnosed with HCV and received DAA therapy in two tertiary centers in Turkey were retrospectively collected. Results: Among them, 75 patients (52.4%) were noncirrhotic and 68 patients (47.6%) were cirrhotic. The overall SVR rate was 97.2% (139/143). It was 100% in noncirrhotic and 94.1% in cirrhotic patients. HCC was developed in 5 (7.4%) patients, all of whom had baseline cirrhosis. The annual rate of HCC occurrence was 2.94%, and the 5-year cumulative incidence of HCC was 7.3%. The mean Child-Pugh score (CPS) and Model for End-Stage Liver Disease (MELD) score significantly decreased after DAA treatment (CPS 7.0 vs 5.9, p=0.001; MELD 10.8 vs 9.5, p=0.003). Conclusion: There was no significant increase in the rate of HCC in cirrhotic HCV patients treated with DAAs. This treatment led to a remarkably high SVR rate and lowered CPS and MELD scores in cirrhotic HCV patients.

Characteristics of Newly Diagnosed Hepatocellular Carcinoma Patients Across Turkey: Prospective Multicenter Observational 3K Registry Study.

AIMS: To evaluate patient profile for epidemiological and clinicopathological characteristics and potential risk/prognostic factors in newly diagnosed hepatocellular carcinoma (HCC) patients across Turkey. METHODS: A total of 547 patients (mean (SD) age 62.6 (10.3) years, 81.9% were males) were included in this registry study. Data on patient characteristics, etiologies of HCC, laboratory values, and tumor characteristics and stages were recorded at study enrollment. RESULTS: HBV infection (68.2%) was the leading etiology, followed by HCV infection (17.2%), HDV infection (5.5%), alcohol (6.4%), and NAFLD (3.5%), as the major etiologies. Considering that 51.6% of the patients had >5 cm HCC, 44% were Child-Pugh B/C and 57% were BCLC B-D, it appears that a significant group of HCC patients were diagnosed at advanced stages. Of 540 patients, 271 (50.2%) were referred or applied with the diagnosis of HCC. Patients with HCC at presentation had larger tumor size (median (min-max) 6.6 (0-30) vs. 4.8 (0-90) cm, P < .001) and more advanced BCLC stage (Stage C-D in 40.8% vs. 26.4%, respectively, P = .005), compared to patients who were diagnosed during follow-up. CONCLUSIONS: Our findings revealed that HBV infection was the leading etiology and a moderate-to-advanced disease was evident in more than half of patients at the time of diagnosis. HCC patients diagnosed at follow-up had smaller tumor size and earlier BCLC stage.

Brucellosis as a rare cause of granulomatous hepatitis with hepatic and bone marrow granulomas: A case report.

Brucellosis is a zoonotic infection that may involve the liver in a variety of ways, however, data on the histopathology of liver effects in brucellosis are limited. Brucellosis is generally characterized by a high fever, joint or back pain, and hepatosplenomegaly. This report illustrates a case of granulomatous hepatitis with granulomas in the liver and bone marrow in a patient who presented with non-specific symptoms, hepatomegaly, splenomegaly, digital clubbing, and laboratory signs of intrahepatic cholestasis. Granulomas were detected in the bone marrow and hepatic specimens. The diagnosis of brucellosis was based on the isolation of Brucella mellitensis in a blood culture and serum agglutination titers of 1:640. Treatment for brucellosis led to improved laboratory and clinical findings. Brucellosis should be considered in regions where it is endemic in cases of an elevated transaminase level and related clinical findings. Brucellosis should also be considered in the differential diagnosis of intrahepatic cholestasis and/or granulomas in hepatic and bone marrow biopsies. This case report provides valuable histopathological features and detailed information of liver involvement in a case of brucellosis.

Serum levels of inflammatory markers CRP, ESR and albumin in relation to survival for patients with hepatocellular carcinoma.

INTRODUCTION: Hepatocellular carcinoma is associated with several chronic inflammatory conditions. It is increasingly understood that the inflammation may be part of the carcinogenic process and prognostically important. OBJECTIVE: To evaluate the serum levels of three inflammation markers in relation to survival in HCC patients. METHODS: We retrospectively examined the serum levels of CRP, albumin and ESR, both singly and in combination, in relation to patient survival. RESULTS: Survival worsened with increase in CRP or ESR or decrease in albumin levels. Combinations of CRP plus albumin or CRP plus ESR were associated with an even greater range of survival (3-fold), together with significant differences in maximum tumor diameter (PVT) and percent of patients with portal vein thrombosis (PVT). The triplet of CRP plus albumin plus ESR was associated with a sevenfold difference in survival, comparing low vs high parameter levels. These significant differences were found in patients with small or large tumors. CONCLUSIONS: Combinations of CRP with albumin or ESR or all three parameters together significantly related to differences in survival and to differences in MTD and percent PVT, in patients with both small and large size HCCs.

Ten-year follow-up of a randomized controlled clinical trial in chronic hepatitis delta.

Hepatitis delta virus (HDV) infection causes the most severe form of viral hepatitis. PEG-interferon alpha-2a (PEG-IFNα-2a) is the only effective treatment but its long-term clinical impact is unclear. The aim of this study was to investigate the long-term outcome after 48 weeks of pegylated interferon alpha-2a therapy. We performed a retrospective follow-up study of the Hep-Net-International-Delta-Hepatitis-Intervention-Study 1 (HIDIT-I trial). Patients had received 48 weeks of treatment with either PEG-IFNα-2a plus adefovir dipivoxil (ADV) (Group I), PEG-IFNα-2a alone (Group II) or adefovir dipivoxil alone (Group III). Liver-related complications were defined as liver-related death, liver transplantation, liver cancer and hepatic decompensation defined as development of Child-Pugh scores B or C or an increase in Model for End-stage Liver Disease (MELD) scores of five or more points in relation to baseline values. Patients were considered for further analysis when they were retreated with PEG-IFNα-2a. Follow-up data (at least 1 visit beyond post-treatment week 24) were available for 60 patients [Group I, (n = 19), Group II (n = 20), Group III (n = 21)]. Mean time of follow-up was 8.9 (1.6 - 13.4) years. 19 patients were retreated with IFN-based therapy: 42% (n = 8) in PEG-IFNα-2a arms and 58% (n = 11) in the adefovir only arm. Clinical complications on long-term follow-up occurred in 17 patients and were associated with nonresponse to therapy and baseline cirrhosis. The annual event-free survival rate in patients with cirrhosis vs noncirrhotic patients at year 5 and 10 was 70% vs 91% and 35% vs 76%. Long-term follow-up of a large randomized clinical trial suggests that off-treatment HDV RNA response to PEG-IFNα-2a treatment leads to improved clinical long-term outcome.

Real-world efficacy and safety of Ledipasvir + Sofosbuvir and Ombitasvir/Paritaprevir/Ritonavir ± Dasabuvir combination therapies for chronic hepatitis C: A Turkish experience.

BACKGROUND/AIMS: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population. MATERIAL AND METHODS: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)±ribavirin (RBV) orombitasvir/paritaprevir/ritonavir±dasabuvir (PrOD)±RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed. RESULTS: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90±54.60 U/L to 17.00±14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51±4.54 to 7.32±3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0±16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%). CONCLUSION: LDV/SOF or PrOD±RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.

Inflammatory markers C-reactive protein and PLR in relation to HCC characteristics.

INTRODUCTION: Several markers of systemic inflammation, including blood C-reactive protein, platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) have been identified as independent prognosticators for hepatocellular carcinoma (HCC). METHODS: To attempt to understand the significance of these markers, they were examined in relation to 4 tumour parameters, namely maximum tumour diameter (MTD), tumour multifocality, portal vein thrombosis (PVT) and blood alpha-fetoprotein (AFP) levels. RESULTS: Using linear and logistic regression models, we found that C-reactive protein and PLR on single variables, were statistically significantly related to the tumour parameters. In a logistic regression final model, CRP was significantly related to MTD, AFP and PVT, and the Glasgow Index significantly related to MTD and AFP. Results of the area under the receiver operating characteristic curves (ROC), showed that the areas for PLR and CRP were statistically significant for high versus low MTD and for presence versus absence of PVT. CRP alone was significant for high versus low AFP. CONCLUSIONS: These analyses suggest that the prognostic usefulness of the inflammatory markers PLR and CRP (but not NLR) may be due to their reflection of parameter values for tumour growth and invasiveness.

C-Reactive Protein and Platelet-Lymphocyte Ratio as Potential Tumor Markers in Low-Alpha-Fetoprotein Hepatocellular Carcinoma.

The hepatocellular carcinoma (HCC) tumor marker alpha-fetoprotein (AFP) is only elevated in about half of the HCC patients, limiting its usefulness in following the effects of therapy or screening. New markers are needed. It has been previously noted that the inflammation markers C-reactive protein (CRP) and platelet-lymphocyte ratio (PLR) are prognostically important and may reflect HCC aggressiveness. We therefore examined these 2 markers in a low-AFP HCC cohort and found that for HCCs > 2 cm, both markers significantly rise with an increasing maximum tumor diameter (MTD). We calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Youden index value for each marker, and their area-under-the-curve values for each MTD group. Patients were dichotomized into 2 groups based on the CRP and PLR from the receiver-operating characteristic curve analysis. In the logistic regression models of the 4 different MTD patient groups, CRP and PLR levels were statistically significant to estimate MTD in univariate logistic regression models of MTD groups > 2 cm. CRP and PLR were then combined, and the combination was statistically significant to estimate MTD groups of 3-, 4-, and 5-cm cutoffs. CRP and PLR thus have potential as tumor markers for low-AFP HCC patients, and possibly for screening.

Macroscopic Portal Vein Thrombosis in HCC Patients.

Macroscopic portal vein invasion (PVT) by hepatocellular carcinoma (HCC) in the liver is one of the most important negative prognostic factors for HCC patients. The characteristics of a large cohort of such patients were examined. We found that the percent of patients with PVT significantly increased with increasing maximum tumor diameter (MTD), from 13.7% with tumors of MTD <5cm to 56.4% with tumors of MTD >10cm. There were similar numbers of HCC patients with very large tumors with and without PVT. Thus, MTD alone was insufficient to explain the presence of PVT, as were high AFP levels, since less than 50% of high AFP patients had PVT. However, the percent of patients with PVT was also found to significantly increase with increasing blood alpha-fetoprotein (AFP) levels and tumor multifocality. A logistic regression model that included these 3 factors together showed an odds ratio of 17.9 for the combination of MTD>5.0cm plus tumor multifocality plus elevated AFP, compared to low levels of these 3 parameters. The presence or absence of macroscopic PVT may therefore represent different HCC aggressiveness phenotypes, as judged by a significant increase in tumor multifocality and AFP levels in the PVT positive patients. Factors in addition to MTD and AFP must also contribute to PVT development.

C-reactive protein and hepatocellular carcinoma: analysis of its relationships to tumor factors.

C-reactive protein (CRP) is a blood marker for inflammation and is an independent prognostic factor for many human cancers. Combined with albumin levels, it forms the basis of the Glasgow Index for cancer prognosis. We reviewed the literature on CRP and HCC and also evaluated blood CRP levels and combination CRP plus albumin levels in a large HCC cohort. In order to understand the prognostic significance of CRP, we retrospectively examined a large HCC cohort and examined the relationship of CRP levels to tumor parameters. We report, that CRP alone and CRP plus albumin combined as well, significantly correlated with parameters of HCC aggressiveness, such as maximum tumor dimension (MTD), portal vein thrombosis (PVT) and blood alpha-fetoprotein (AFP) levels, both as individual parameters and all parameters together (Aggressiveness Index). This extends current thinking, to suggest a possible explanation for the usefulness of blood CRP levels in HCC prognostication.

HCC with low- and normal-serum alpha-fetoprotein levels.

A large database of 1773 HCC patients in Turkey was examined. 41.9% had alpha-fetoprotein (AFP) levels <20 IU/ml and an additional 16.123% had values between 20-100 IU/ml. This 58% of the cohort (<100 IU/ml AFP levels) was examined in detail. 66% of patients with small (<5 cm) HCCs had low AFP, compared to 49% of patients with larger (>5 cm) HCCs. The mean diameter (MTD) of larger MTD, low AFP tumors was 8.4cm. Therefore, factors other than AFP must contribute to HCC tumor growth. Larger tumors in low AFP patients had both higher platelet levels and increased PVT percent. Linear regression analysis for both MTD and multifocality showed that platelet numbers and presence of PVT were significant variables; whereas for PVT, significant variables were albumin, alkaline phosphatase and MTD. Comparisons between patients with AFP levels <20, 20-<100, 100-<1000 and >1000 IU/ml showed the most significant tumor finding was an increase in PVT percent between each group, and to a lesser extent, MTD. Thus, low- or normal-AFP HCCs constitute the majority of patients and have slightly lower MTD and much lower PVT percent than HCCs associated with elevated blood AFP levels. New, non-AFP markers are thus needed, especially for small HCCs.

Association Between Level of Hepatitis D Virus RNA at Week 24 of Pegylated Interferon Therapy and Outcome.

BACKGROUND & AIMS: Interferon is the only effective treatment for chronic hepatitis D virus (HDV) infection. No rules have been set for stopping treatment based on viral kinetics. We analyzed data from an international study of hepatitis D treatment to identify factors associated with outcomes of pegylated interferon treatment, with and without adefovir. METHODS: We analyzed data from the Hep-Net-International Delta Hepatitis Intervention Trial on 50 patients with compensated liver disease who tested positive for anti-HDV and HDV RNA. Subjects received pegylated interferon α 2a, with adefovir or placebo, or only adefovir, for 48 weeks. Twenty-four weeks after treatment ended, 41 patients were evaluated for levels of HDV RNA and DNA, liver enzymes, and hepatitis B surface antigen (HBsAg); liver biopsy specimens were analyzed for fibrosis. Response to therapy was defined as end-of-treatment response or post-treatment week 24 virologic response. In both cases virologic response was associated with undetectable HDV RNA levels. Patients with less than a 1 log decrease in HDV RNA at the end of treatment were considered null responders. RESULTS: Based on univariate and multivariate analysis, the level of HDV RNA at week 24 of treatment was associated more strongly with response to therapy than other factors analyzed. The level of HBsAg at week 24 of treatment was associated with a response to therapy only in univariate analysis. Lack of HDV RNA at week 24 of treatment, or end of treatment, identified responders with positive predicted values of 71% and 100%, respectively. At 24 weeks after treatment, a decrease in HDV RNA level of less than 1 log, combined with no decrease in HBsAg level, identified null responders with a positive predictive value of 83%. A decrease in HDV RNA level of more than 2 log at week 24 of treatment identified null responders with a negative predictive value of 95%. CONCLUSIONS: Based on an analysis of data from a large clinical trial, the level of HDV RNA at week 24 of treatment with pegylated interferon, with or without adefovir for 48 weeks, can identify patients who will test negative for HDV RNA 24 weeks after the end of treatment. This information can be used to help physicians manage patients receiving therapy for chronic hepatitis D.

Chronic hepatitis B associated with hepatic steatosis, insulin resistance, necroinflammation and fibrosis.

BACKGROUND: The effect of hepatitis B virus (HBV) infection on fatty liver disease is unclear. OBJECTIVES: The aim of this study was to investigate the viral and host causes of fatty liver in chronic hepatitis B (CHB) patients. This study included 88 CHB patients of which 17 were not treated. Liver biopsy was performed in each patient. Group 1 included those with hepatic steatosis (n=28) and group 2 those without hepatic steatosis. The groups were compared in terms of age, body mass index (BMI), Homeostasis Model Assessment- Insulin Resistance (HOMA-IR), viral load, biochemical parameters and histological findings. Patients in group 1 were subdivided according to the degree of steatosis as follows: grade 1 (15 patients, 53.6%), grade 2 (6 patients, 21.4%), and grade 3 (7 patients, 25%). RESULTS: In group 1 (n=28), mean age, BMI, cholesterol, and HOMA-IR were found to be significantly higher than in group 2 (n=60). There were no significant differences in the positivity of viral load, HbeAg, treatment, fibrosis and other laboratory parameters between the two groups. HOMA-IR was the only independent predictive factor of liver steatosis in patients with CHB in logistic regression analysis. CONCLUSION: Hepatic steatosis in CHB patients was associated with host metabolic factors.

Late HDV RNA relapse after peginterferon alpha-based therapy of chronic hepatitis delta.

UNLABELLED: Interferon alpha is the only treatment option for hepatitis delta virus (HDV). Trials investigating the efficacy of pegylated interferon alpha (PEG-IFNa) showed HDV RNA negativity rates of 25-30% 24 weeks after therapy. However, the clinical and virological long-term outcome of HDV-infected patients treated with PEG-IFNa is unknown. We performed a retrospective-prospective follow-up of 77 patients treated for 48 weeks with either PEG-alfa-2a and adefovir (ADV) or either drug alone in the Hep-Net-International-Delta-Hepatitis-Intervention-Study 1 (HIDIT-1) trial. Long-term follow-up data were available for 58 out of 77 patients (75%) with a median time of follow-up of 4.5 (0.5-5.5) years and a median 3 visits per patient. Patients treated with ADV alone received retreatment with PEG-IFNa (48% versus 19%; P = 0.02) more often. Hepatitis B virus surface antigen (HBsAg) became negative in six PEG-IFNa-treated patients until the end of long-term follow-up (10%). Sixteen patients tested HDV RNA-negative 6 months after PEG-IFNa treatment who were entered in the long-term follow-up study. Out of these, nine individuals tested HDV RNA-positive at least once during further long-term follow-up, with seven patients being HDV RNA-positive at the most recent visit. Clinical endpoints (liver-related death, liver transplantation, hepatic decompensation, hepatocellular carcinoma) were observed in three PEG-IFNa-treated (8%) and three ADV-treated (14%) patients during posttreatment long-term follow-up with an overall annual event rate of 2.5% (4.9% in cirrhosis). Sequencing confirmed the reappearance of pretreatment virus strains in all cases. CONCLUSION: Late HDV RNA relapses may occur after PEG-IFNa therapy of hepatitis delta and thus the term sustained virological response should be avoided in HDV infection. The annual posttreatment rate of clinical events in hepatitis delta patients eligible for PEG-IFNa therapy is about 2.5% and 4.9% in patients with cirrhosis.

Pegylated interferon-based treatment in patients with advanced liver disease due to chronic delta hepatitis.

BACKGROUND/AIMS: The safety and efficacy of interferons in advanced delta hepatitis have not been explored. The aim of this subanalysis of a multicenter clinical trial was to compare the efficacy and safety of 48 weeks of pegylated interferon alpha-2a (180 µg weekly) with or without adefovir (10 mg daily) in patients with chronic delta hepatitis-induced advanced liver disease and in those with non-advanced liver disease. MATERIALS AND METHODS: Thirty-one patients with advanced and 27 patients with non-advanced liver disease were assessed. Patients were considered to have advanced liver disease when biopsy disclosed a fibrosis score of ≥4 according to Ishak or when imaging studies were indicative of cirrhosis. Virologic response, defined as achievement of undetectable hepatitis D virus RNA, was assessed at the end of treatment and end of 24 weeks of treatment-free follow-up. RESULTS: Patients with advanced disease had lower hepatitis D virus RNA levels and platelet counts (p=0.014 and p=0.0015, respectively). End of treatment and end of follow-up virologic responses in patients with advanced vs. non-advanced liver disease were similar (29% vs. 19% and 32% vs 23%). Proportion of adverse events did not differ between groups except that thrombocytopenia was noted more often in the advanced liver disease group. Further, four cases of clinically important adverse events including two cases of hepatic decompensation and one case of tuberculosis reactivation occurred in the advanced liver disease group. CONCLUSIONS: Pegylated interferon is as effective in patients with advanced liver disease due to chronic delta hepatitis as in patients with non-advanced liver disease, but patients should be monitored closely for clinically important side effects.

The prevalence of hepatitis delta virus infection in acute and chronic liver diseases in Turkey: an analysis of clinical studies.

BACKGROUND/AIMS: The objective of this study was to review the studies on hepatitis D virus-related liver diseases and to evaluate the national and regional outcomes in order to identify the hepatitis D virus infection in Turkey. METHODS: This retrospective study included 2182 acute viral hepatitis, 6613 inactive HBsAg carriers, 5961 chronic hepatitis B, 1264 liver cirrhosis and 748 hepatocellular carcinoma cases, who were evaluated for anti-hepatitis D virus positivity at several centers in Turkey since 1980's. ELISA method was used and the results were statistically evaluated. RESULTS: The anti-hepatitis D virus positivity was 3.0% in 1416 acute viral hepatitis and 8.1% in 766 acute hepatitis B cases. This ratio was significantly higher in Diyarbakir than in Istanbul and Ankara for acute viral hepatitis (p<0.001). The mean anti-hepatitis D virus was 4.9% in inactive HBsAg carriers and significantly decreased from 1980 to 2005 (4.1% and 2.9%, respectively p<0.001). The anti- hepatitis D virus was 20% in chronic hepatitis B and 32.5% in liver cirrhosis cases. The positivity were significantly lower in Istanbul and Izmir compared to Diyarbakr and Van (p<0.001). Antihepatitis D virus positivity was decreased in all regions for the last two decades (p<0.001). The rates decreased from 31% to 11% for chronic hepatitis B and from 43.3% to 24% for liver cirrhosis (p<0.001). The mean anti-hepatitis D virus was 23% in hepatocellular carcinoma cases, which was significantly lower in Istanbul and Izmir compared to Diyarbakr and Elaz currency (p<0.0001). CONCLUSIONS: The hepatitis D virus infection is a critical problem in our country, particularly in the Eastern and Southeastern Anatolia. In recent years, the hepatitis D virus infection is decreasing countrywise, however the rate still remains to be critical.

Intracranial multiple tuberculomas: 2 unusual cases.

BACKGROUND: Tuberculosis (TB) is still a major public health problem that continues to be an important cause of morbidity and mortality at worldwide level. Only 1% of patients with TB develop an intracranial tuberculoma (Tbm), usually as part of miliary TB. The radiological findings are often nonspecific, and they are difficult to diagnose without an increased index of suspicion. CASES DESCRIPTIONS: In this report, we presented 2 unusual patients with intracranial multiple Tbms, one of whom is a 32-year-old woman who did not have pulmonary TB or other primary origin of TB. Her diagnosis was established histopathologically, and she was treated with antituberculous chemotherapy. The other patient is a 12-year-old girl who has pulmonary TB with portal hypertension together with liver cirrhosis. Her diagnosis was established with clinical, radiological, and laboratory findings, and she was treated with antituberculous chemotherapy for 18 months. CONCLUSIONS: Intracranial Tbms have become rare in developed countries, but TB is still a very common infectious disease at worldwide level. Therefore, diagnosis should be kept in mind when confronted with brain space-occupying lesions, especially in the immunocompromised or malnutritional hosts such as liver cirrhosis. When no other active extracranial tuberculous process is found, the diagnosis should be confirmed by a biopsy before beginning antituberculous treatment, which is rapidly effective. We have not encountered in the literature such a case of multiple intracranial Tbms associated with liver cirrhosis in an adult patient.

A three-month course of lamivudine therapy in HBeAg-positive hepatitis B patients with normal aminotransferase levels.

BACKGROUND/AIMS: HBeAg-positive patients with normal ALT levels are unlikely to respond to current therapy. In addition, there is a high risk of hepatocellular carcinoma in HBeAg-positive patients in the natural course of HBV infection. For this purpose, we aimed to investigate the clinical efficacy and safety of a three-month course of lamivudine therapy in HBeAg-positive hepatitis B patients with normal aminotransferase levels for assessing a more practical and economical approach to these patients. METHODS: Forty-six patients were prospectively randomized into two groups. Group A consisted of 13 patients treated with lamivudine 100 mg/day, for 12 weeks [7 males, mean age 23.30+/-5.82 years, median ALT of 27 IU/L (21-40), median HBV DNA of 4116 pg/ml (2885-6628)]. Group B consisted of 33 patients without treatment [18 males, mean age 24.75+/-6.92 years, median ALT of 30 IU/L (19-39), median HBV DNA of 4094 pg/ml (782-7387)]. Main outcome measure was sustained virologic response, which was defined as loss of HBV DNA in serum with HBeAg seroconversion at least 12 months thereafter. Follow-up lasted 12 months after the first dose. RESULTS: No significant effects were observed in the treated population in the reduction of HBV DNA to undetectable levels, in HBeAg/anti-HBe seroconversion, or in transaminase levels. At the end of follow-up, sustained virologic response was almost similar in the study as well as control group (7.6% vs. 3.0%, p=0.502). None of the 13 patients who received lamivudine therapy had HBeAg seroconversion during the study period. In addition, the suppression of serum HBV DNA was temporary; prolonged suppression could be achieved in only one patient in the follow-up period. The median levels of HBV DNA and ALT values between baseline and month 12 did not differ significantly between groups. All patients remained HBsAg positive and none developed anti-HBs. The therapy was well tolerated and post-therapy flare was not observed in any patient after stopping lamivudine therapy. CONCLUSIONS: A short course of lamivudine therapy resulted mostly in only temporarily depressed serum HBV DNA levels without significant change in viral clearance. Whether permanent suppression of HBV DNA can be achieved in this special population of HBsAg carriers by long-term treatment with lamivudine awaits further controlled trials. New and safe modalities of therapy are needed for the satisfactory treatment of these asymptomatic but viremic patients.
