The significance of Meckel's scan in pediatric gastrointestinal bleeding cases: A case report.

Meckel's diverticulum is the most prevalent congenital anomaly of the gastrointestinal tract, identified in 2% of the population according to autopsy studies. Most patients remain asymptomatic throughout their lives and are typically diagnosed when complications arise. The diagnosis can be challenging, but imaging is crucial for promptly identifying and distinguishing it from other conditions that have similar clinical manifestations. A 13-year-old male was admitted with a 5-day history of rectal bleeding. The patient continued to experience painless gastrointestinal bleeding, indicating the performance of a Tc-99m pertechnetate scintigraphy or Meckel's scan. Planar images revealed focal uptake within the right hemiabdomen, suggestive of the presence of a Meckel's diverticulum. Subsequent laparotomy surgery confirmed the presence of a Meckel's diverticulum located 50 cm from the ileocecal valve. Histopathological examination of the resected specimen confirmed Meckel's diverticulum with ectopic gastric mucosa. This patient with Meckel's diverticulum exhibited minimal abdominal symptoms, and there were no other complications such as intussusception, which could lead to bowel obstruction. Technetium-99m pertechnetate scintigraphy is a common method for evaluating children with unexplained gastrointestinal tract bleeding. SPECT/CT fusion imaging enables the simultaneous fusion of functional and anatomical information, preventing false-negative scintigraphy examinations. Its capability to precisely localize activity in abnormal structures contributes to accurate scan interpretation. Complications of Meckel's diverticulum are uncommon and pose a diagnostic challenge. Through comprehensive history-taking, physical examination, and nuclear imaging, the diagnosis can be identified, and surgical intervention can be performed to achieve the best possible outcome for the patient.

Estimated projection of oral squamous cell carcinoma annual incidence from twenty years registry data: a retrospective cross-sectional study in Indonesia.

Background: The incidence of oral squamous cell carcinoma (OSCC) has not been well documented in Indonesia. Thus, we aimed to analyze trends and clinicopathological profiles of OSCC cases in Indonesia, focusing on differences between age and sex groups. Methods: A cross-sectional study was conducted in Indonesia's main referral hospital, analyzing 1,093 registered OSCC cases from 2001 to 2020. Trend analysis was performed using Joinpoint regression analysis to determine the annual percentage change (APC) for overall cases and each case group based on age, sex, and anatomical subsites. APC significance was assessed using a Monte Carlo permutation test. The projection of case numbers for the following 5 years (2021-2025) was estimated using linear/non-linear regression analysis and presented as a mathematical function. The significance of the trend slope was measured using an ANOVA test. Demographic and clinicopathological characteristics of OSCC were analyzed according to age and sex, and their comparative analysis was assessed using Chi-square and its alternatives. Results: The incidence of OSCC in female patients and in the tongue and buccal mucosa showed a positive trend (APC 2.06%; 3.48%; 8.62%, respectively). Moreover, the incidence of OSCC overall, and in women with OSCC, is projected to increase significantly in the next 5 years following the quadratic model. The mean age of patients was 51.09 ± 14.36 years, with male patients being younger than female patients. The male-to-female ratio was 1.15, and 36.5% of these patients were categorized as young (≤45 years old). The tongue was the predominantly affected site. Prominent pathologic characteristics included well-differentiation, keratinization, and grade I of Bryne's (1992) cellular differentiation stage. Most patients presented with advanced staging, lymphovascular invasion, and uninvaded margins. Tumor sites and staging varied according to age, while age and tumor sites differed between sexes. Conclusion: The rising incidence trends of OSCC among Indonesian patients, both in the past and projected future, are concerning and warrant attention. Further research into risk factors should be conducted as preventive measures.

p53 expression is associated with tumor stage, grade and subtype in patients with hepatocellular carcinoma.

The present study aimed to determine the expression levels of p53 in patients with hepatocellular carcinoma (HCC) and to evaluate its association with several HCC-related prognostic factors and in particular, with tumor stage, grade and subtype. Therefore, a cross-sectional study, involving 41 patients with HCC, who underwent surgical resection between January, 2013 and December, 2020 was conducted. To assess the expression levels of p53 in all patients with HCC, immunohistochemical staining was performed. In addition, the association between p53 expression and the clinicopathological characteristics of patients with HCC, including prognostic factors, was evaluated by applying the appropriate statistical analysis methods. The results revealed that among the 41 patients enrolled, 35 patients (85.4%) were positive for p53 expression. A higher percentage of positive p53 expression was observed in male patients >60 years old, with single HCC nodules >5 cm in diameter and vascular invasion, compared with their counterparts. A positive p53 expression was associated with well- and poorly differentiated HCC, but not with tumor stage and subtype. No differences in p53 expression were observed across different tumor stages and subtypes. Additionally, patients with moderately and poorly differentiated HCC exhibited significantly higher p53 expression levels compared with those suffering from well-differentiated HCC. Overall, the results demonstrated that the rate of p53 immuno-positive cells was increased in patients with HCC. In addition, p53 expression was associated with well- and poorly differentiated HCC, thus suggesting its association with a poorer prognosis.

Clinical implications of Cytokeratin 19 expression in patients with oral squamous cell carcinoma.

Objective: This study was done to quantify the prevalence of high cytokeratin (CK) 19 expression in Indonesian oral squamous cell carcinoma (OSCC) patients and explore the prognostic role of CK19 in OSCC. Methods: Clinical data and samples from 61 patients diagnosed with OSCC at a tertiary national referral hospital in Jakarta, Indonesia were analyzed in this retrospective cohort study. Immunohistochemical staining of CK19 was performed on all patients and its expression was scored using the H system. All patients were followed up for a minimum of 36 months after diagnosis. Comparative and survival analyses were performed. Results: Twenty six point two percent of Indonesian OSCC patients had high CK19 expression. There were no differences in clinicopathological characteristics between patients with low and high CK19 expression. The 3-year overall survival (OS) of our cohort was 11.5%. Patients with high CK19 expression had lower 3-year OS compared to patients with low CK19 expression, even if the difference in OS was not statistically significant. Keratinization was an independent prognostic factor for survival in multivariate regression analysis. Conclusions: Data obtained here indicate a possible prognostic role of CK19 in OSCC. This prognostic role should be confirmed in larger series.

Clinicopathological characteristics predicting advanced stage and surgical margin invasion of oral squamous cell carcinoma: A single-center study on 10 years of cancer registry data.

The incidence profile of oral squamous cell carcinoma (OSCC) has not previously been comprehensively reported in Indonesia. The present study aimed to identify clinicopathological characteristics of patients with OSCC according to sex and age, to analyze histological differentiation patterns specific to tumor subsites, to highlight the role of lymphovascular invasion (LVI) in metastasis, and to develop a model to predict advanced stage and margin invasion. A retrospective cross-sectional study was performed using 581 medical records and pathological specimens from cancer registry data in the Dr Cipto Mangunkusumo Hospital (Jakarta, Indonesia), between January 2011 and December 2020. Clinicopathological characteristics were analyzed using parametric and non-parametric tests. Multivariate logistic regression analyses were performed for eligible parameters, identified using bivariate analysis, to predict advanced stage and margin invasion. Calibration of the prediction model was evaluated using the Hosmer-Lemeshow test, its discrimination value assessed using the receiver operating characteristic and area under the receiver operating characteristic curve (AUC). Sex-specific patterns in tumor subsites and differences in clinical staging according to age were demonstrated in the patients with OSCC. The proportion of well-differentiated cases was significantly higher in most tumor subsites, except in the buccal mucosa (more moderately differentiated cases) and floor of the mouth (well and moderately differentiated cases being equal). LVI was significantly associated with nodal metastasis but not distant metastasis. Multivariate analysis demonstrated that age ≤45 years [odds ratio (OR), 2.26] and LVI (OR, 8.42) predicted patients having advanced-stage OSCC among general populations (AUC, 0.773); however, LVI (OR, 8.28) was the sole predictor of advanced stage amongst young patients (AUC, 0.737). Margin invasion was predicted solely by tumor subsite, including mouth not otherwise specified (OR, 3.04) and palate (OR, 6.13), in the general population (AUC, 0.711). Furthermore, margin invasion was predicted by the palate subsite (OR, 38.77) and LVI (OR, 11.61) in young patients (AUC, 0.762). Investigating young patients thoroughly when finding SCC in the mouth and palate, and assessing LVI, especially among young patients, is critical to prevent advanced staging and margin invasion.

Fulminant necrotizing amoebic colitis presenting as acute appendicitis: a case report and comprehensive literature review.

Intestinal amoebiasis is a parasitic infection caused by Entamoeba histolytica. It is commonly found in developing countries with poor hygiene. A rare, life-threatening complication of amoebiasis is fulminant necrotizing amoebic colitis (FulNAC). We report a 59-year-old male with acute lower right abdominal pain. Before coming to our institution, he was diagnosed with acute appendicitis. Extensive necrosis near the caecum involving the appendix and colon was observed intraoperatively. The patient underwent a right hemicolectomy, followed by an ileostomy and colostomy. Histopathologic examination confirmed the diagnosis of FulNAC. After the surgery, the patient was transferred to the high care unit and treated with metronidazole after histopathologic findings confirmed the etiology. The patient showed excellent response to the antibiotic prescribed, and the symptoms subsided. He was discharged from the hospital on day nine. Additionally, we reviewed fifty-one existing case reports on invasive intestinal amoebiasis worldwide, confirmed by histopathological examination following their preoperative diagnosis, surgery, pharmacology treatment, and outcomes. The learning point of this case is that intestinal amoebiasis should be considered a differential diagnosis for patients around fifty years old with bowel symptoms and travel history or living in tight quarters. Blood tests, radiological examinations, and serological evaluations are valuable diagnostic modalities. Metronidazole should be given as early as possible, and health promotion is recommended to prevent this disease in the population.

Analysing 11 years of incidence trends, clinicopathological characteristics, and forecasts of colorectal cancer in young and old patients: a retrospective cross-sectional study in an Indonesian national referral hospital.

OBJECTIVE: To obtain annual incidence trends, understand clinicopathological characteristics, and forecast the future burden of colorectal cancer (CRC) in Indonesia. DESIGN: 11-year retrospective cross-sectional study. SETTING: A national referral hospital in Jakarta, Indonesia. PARTICIPANTS: Data from 1584 eligible cases were recorded for trends and forecasting analyses; 433 samples were analysed to determine clinicopathological differences between young (<50 years) and old (≥50 years) patients. METHODS: Trend analyses were done using Joinpoint software, expressed in annual percentage change (APC), and a regression analysis was executed to generate a forecasting model. Patients' characteristics were compared using χ2 or non-parametric tests. MAIN OUTCOMES: Analysis of trends, forecasting model, and clinicopathological features between the age groups. RESULTS: A significant increase in APC was observed among old patients (+2.38%) for CRC cases. Colon cancer increased remarkably (+9.24%) among young patients; rectal cancer trends were either stable or declining. The trend for right-sided CRC increased in the general population (+6.52%) and old patients (+6.57%), while the trend for left-sided CRC was stable. These cases are expected to be a significant health burden within the next 10 years. Patients had a mean age of 53.17±13.94, 38.1% were young, and the sex ratio was 1.21. Prominent characteristics were left-sided CRC, tumour size ≥5 cm, exophytic growth, adenocarcinoma, histologically low grade, pT3, pN0, inadequately dissected lymph nodes (LNs), LN ratio <0.05, no distant metastasis, early-stage cancer, no lymphovascular invasion, and no perineural invasion (PNI). Distinct features between young and old patients were found in the histological subtype, number of dissected LN, and PNI of the tumour. CONCLUSIONS: Epidemiological trends and forecasting analyses of CRC cases in Indonesian patients showed an enormous increase in colon cancer in young patients, a particularly concerning trend. Additionally, young patients exhibited particular clinicopathological characteristics that contributed to disease severity.

Ulcerative Colitis as the Rarer Phenotype of Inflammatory Bowel Disease to Coexist with Psoriatic Arthritis: A Case Report.

Psoriatic arthritis (PsA) has been linked to various diseases associated with immune dysregulation, such as Inflammatory Bowel Disease (IBD). Numerous studies have shown strong correlation between PsA and one of the phenotypes of IBD, Crohn's disease. On the other hand, the studies regarding the association of PsA with ulcerative colitis (UC) are less robust and have conflicting findings. We herein report a case of 56-year-old woman with a history of psoriatic arthritis, who developed chronic diarrhea and significant weight loss. The colonoscopy and histopathologic findings were suggestive of pancolitis with backwash ileitis, from which the working diagnosis of ulcerative colitis was carried out. The patient fit the typical epidemiological profile of a PsA patient with concomitant UC, but some aspects of the clinical features observed in this case, such as the development of anterior uveitis was rarely documented in similar studies. A conducted bidirectional meta-analysis also showed that there were more cases where UC preceded the diagnosis of psoriasis, which makes the late development of UC in this case atypical. Due to the uncommon nature of the concurrent development of these two disease entities in this case, this study could provide additional insights to the association of PsA and UC.

The Clinical Significance of Colon Polyp Pathology in Nonalcoholic Fatty Liver Disease (NAFLD) and Its Impact on Screening Colonoscopy in Daily Practice.

Aim: Nonalcoholic fatty liver disease (NAFLD) has been known as a risk for the presence of colon polyp and CRC development. This study was aimed to find out the clinical significance of colon polyps' pathology among NAFLD patients. Method: A retrospective database study was done in patients who underwent elective colonoscopy within one-year period in a referral private hospital, Jakarta. Subjects were adult patients who also had documented abdominal ultrasound (US). The association between NAFLD and colonic polyp was analyzed using Chi-square test with odds ratio (OR) and its corresponding 95% confidence interval (CI). Results: A total of 138 adult patients were enrolled; 68 (51.1%) were men. Patients' mean age was 56.8 ± 15.3 years old. Colon polyps were found in 49 (35.5%) cases; the most common histopathology was adenoma (42.9%). NAFLD was found in 68 (49.3%) of patients. Colon polyps were found to be more among patients with NAFLD than in those without NAFLD (44.1% vs. 27.1%; OR: 2.119; 95% CI: 1.040-4.318). Colon polyps were found in 30 (44.1%) NAFLD patients, where 18 (26.5%) patients had adenomatous polyp, and from this subset of patients with adenomatous polyp, 6 (8.8%) patients had mild dysplasia, 8 (11.8%) had moderate dysplasia, 1 (1.5%) had severe dysplasia, and 3 (4.4%) had adenocarcinoma. Conclusions: NAFLD is associated with increased risk of any colon polyp, regardless of the histopathological type, compared with patients without NAFLD. This finding implies the necessity to perform screening colonoscopy in patients with NAFLD in the future.

Immunohistochemical Staining on an Excision Biopsy Specimen as a Diagnostic Modality for Rare Idiopathic Hepatocellular Adenoma: A Case Report.

Hepatocellular adenoma is an extremely rare benign tumor of the liver which predominantly in young women. Its rare incidence with estimated 3-4 cases per 1.000.000 annually makes it a diagnostic challenge. Here we present a 30-year-old female patient with hepatocellular adenoma without classic risk factors. A series of work up tools have been performed in order to diagnose the condition. None but excision biopsy from segmental resection had been showed to increase diagnostic confidence. This case illustrates the role of immunohistochemical staining from excision biopsy as the best diagnostic modality of hepatocellular adenoma as well as therapeutic modality to prevent malignant transformation.

Extragonadal yolk sac tumor following congenital buccal mature cystic teratoma.

Yolk sac tumor (YST) and teratoma both categorized as germ cell tumor (GCT). YST shows preferential differentiation toward yolk sac structures, while teratoma consists of tissues that originate from at least two embryonic germinal layers. Extragonadal location of YST is rare, whereas extragonadal teratoma is majority presented in nasopharynx area. Mature teratoma tends to be benign although some malignant transformation can occur. Recurrence of teratoma was reported mostly in the case of immature teratoma. YST occurrence after removal of mature teratoma is never reported. It is extremely rare for a second GCT to occur at the same site and with a different histological type. We herein report a case of a female infant presented with YST following a congenital buccal mature teratoma.

Complete Remission after Sequential Therapy of Drug Eluting Beads Transarterial Chemoembolization and Liver Resection in Large Solitary Nodule Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the fifth most prevalent and the second highest cause of death among cancer. The treatment of large solitary nodule HCC is still challenging. Transarterial chemoembolization (TACE) and liver resection are two modalities of therapy in HCC management. However, recurrence rate from each therapy is relatively high. We report a case of 46-year-old man diagnosed with large solitary nodule HCC, who was treated with drug eluting bead TACE (DEB-TACE) prior to liver resection. Studies about this combination are still limited and showed various results.

Functional Dyspepsia with Helicobacter pylori Infection.

Helicobacter pylori infection is commonly found worldwide. In Indonesia, the prevalence of H. pylori infection is 22.1%. The bacteria are responsible for gastritis, peptic ulcer disease (PUD), and gastric cancer.Helicobacter pylori may also has a role in functional dyspepsia. Diagnostic approach consists of noninvasive and invasive examinations. One of the invasive strategy is upper gastrointestinal (UGI) endoscopy and gastric mucosa biopsy.

Short Communication: Few Liver-Infiltrating Cells Express CXCR3 in HIV/HCV Patients Commencing Antiretroviral Therapy.

Coinfections with Hepatitis C virus and human immunodeficiency virus accelerate the progression of both conditions and hamper effective treatment. Here we describe expression of CXCR3 on liver-infiltrating cells and peripheral T cells from coinfected patients commencing antiretroviral therapy (ART) in Indonesia. CXCR3 was expressed by small number of intrahepatic inflammatory cells, mostly in the portal areas. The number of cells did not change on ART and was markedly lower than the number of CD4+ and CD8+ cells in the liver. Data suggest that CXCR3 may contribute to liver infiltration but demonstrate a dynamic situation, changing as the immune system recovers on ART.

Detection rate of colorectal adenoma or cancer in unselected colonoscopy patients: Indonesian experience in a private hospital.

BACKGROUND: Colorectal cancer is currently the third most common cancer in Indonesia, yet colonoscopy--the most accepted mode of screening to date--is not done routinely and national data are still lacking. OBJECTIVE: To determine the detection rate of colorectal cancers and adenomas in unselected patients undergoing colonoscopy for various large bowel symptoms at the Digestive Disease and GI Oncology Centre, Medistra Hospital in Jakarta, Indonesia. MATERIALS AND METHODS: Colonoscopy data from January 2009 to December 2012 were reviewed. New patients referred for colonoscopy were included. Data collected were patient demographic and significant colonoscopy findings such as the presence of hemorrhoids, colonic polyps, colonic diverticula, inflammation, and tumor mass. Histopathological data were obtained for specimens taken by biopsy. Associations between categorical variables were analyzed using chi-square test, while mean differences were tested using the t-test. RESULTS: A total of, 1659 cases were included in this study, 889 (53.6%) of them being men. Polyps or masses were found in 495 (29.8%) patients while malignancy was confirmed in 74 (4.5%). Patients with a polyp or mass were significantly older (60.2 vs 50.8 years; p<0.001; t-test) and their presence was significantly associated with male gender (35.0% vs 23.9%; prevalent ratio [PR] 1.71; 95% confidence interval [CI] 1.38-2.12; p<0.001) and age>50 years (39.6% vs 16.6%; PR 3.29; 95% CI 2.59-4.12; p<0.001). Neoplastic lesions was found in 257 (16.1%), comprising 180 (11.3%) adenomas, 10 (0.6%) in situ carcinomas, and 67 (4.2%) carcinomas. CONCLUSIONS: Polyps or masses were found in 30% of colonoscopy patients and malignancies in 16.1%. These figures do not represent the nation-wide demographic status of colorectal cancer, but may reflect a potentially increasing major health problem with colorectal cancer in Indonesia.

Matrix metalloproteinase-9 (mmp-9) expression in different subtypes of ameloblastoma.

BACKGROUND: Ameloblastoma is a common benign odontogenic tumor of the jaw with a local invasive and highly destructive behavior and can develop in any age, with peak prevalence in 3rd-4th decade. Ameloblastoma can be divided into six histological types: follicular, plexiform, acanthomatous, desmoplastic, granular, and basal cell. Matrix metalloproteinase-9 (MMP-9) (92-kD gelatinase/type IV collagenases = gelatinase B) is involved in bone resorption by degradation of extracellular matrix and osteoclasts recruitment. Recent studies have found that MMP-9 is expressed by ameloblastoma and has a role in ameloblastoma local invasiveness. OBJECTIVE: To analyze MMP-9 expression between different histological types of ameloblastoma. MATERIAL AND METHOD: Forty samples of ameloblastoma were collected through consecutive sampling and the MMP-9 expression was detected using immunohistochemistry. RESULT: All samples showed positive MMP-9 expression with moderate to strong intensity. 82.4 % plexiform type and 83.3 % mixed type have strong immunoexpression, significantly different with follicular type with only 36.4 % (P < 0.05). CONCLUSION: Ameloblastoma plexiform and mixed type have higher MMP-9 expression than ameloblastoma follicular type. Different MMP-9 expression may contribute in different ameloblastoma biological behavior.

Periportal CD4+ cell infiltration increases in HIV/hepatitis C virus-coinfected patients commencing ART, whereas CD8+ cells clear from the liver.

Coinfection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) is common in Asia, but the effects of antiretroviral therapy (ART) are unclear. Histopathological changes in the liver are described in a prospective study of HCV-seropositive HIV-infected patients at Cipto Mangunkusomo Hospital (Jakarta, Indonesia). Liver biopsy specimens were collected at baseline (n = 48) and 48 weeks (n = 34). Ishak scores showed mild but detectable inflammation and/or fibrosis. Levels of portal inflammation declined during ART (P = .03), whereas fibrosis remained (P = .11). Portal infiltration of CD4(+) cells increased during ART (P < .0001), whereas infiltration of CD8(+) cells subsided. Numbers of CD4(+) cells in the liver at baseline correlated with circulating CD4(+) T-cell counts (P = .03-.05). Numbers of liver-infiltrating CD4(+) and CD8(+) cells at baseline were not associates with subsequent experience of an immune restoration disease, which is defined by a rise in alanine transaminase levels during ART.

Prevalence of hepatic steatosis in chronic hepatitis B patients and its association with disease severity.

AIM: to know the prevalence of liver steatosis in chronic hepatitis B (CHB) patients and evaluate whether its presence was associated with a more progressive disease. METHODS: a cross-sectional study was conducted in Cipto Mangunkusumo and Medistra Hospitals, Jakarta on CHB patients between 2007 and 2009. Data on patients' demography, anthropometry, liver function test and hepatitis B serology were collected. Hepatic steatosis was assessed by liver biopsy and graded as mild (<33%), moderate (33-66%) or severe (>66%). Fibrosis stage and necroinflammatory activity were assessed according to the METAVIR system. RESULTS: one-hundred and seventy four patients were enrolled; 99 (56.9%) among them were men. Patients' mean age was 39.9 ± 10.69 years. About 56% of cases were HBeAg negative. The prevalence of liver steatosis was 29.9%. Patients with liver steatosis had significantly higher body mass index (25.1 ± 3.3 vs. 22.7 ± 3.33 kg/m2, p<0.001) and waist circumference (88.3 vs. 79.0 cm; p<0.001). No association between liver steatosis and HBeAg status (p=0.736). There were no differences of log HBV-DNA levels (5.72 ± 1.993 vs. 6.07 ± 2.077; p=0.675) and liver stiffness (8.3 ± 6.28 vs. 9.5 ± 10.18 kPa) between patients with and without liver steatosis. The presence of significant fibrosis (61.5% vs. 69.7%; p=0.295) and necroinflammation (63.5% vs. 65.6%; p=0.789) was not differed between patients with and without liver steatosis. CONCLUSION: liver steatosis was found in 30% of chronic hepatitis B patients. Its presence was mostly associated with central obesity. Unlike chronic hepatitis C, liver steatosis in chronic hepatitis B was not related to a more progressive disease.

Significant hepatic histopathology in chronic hepatitis B patients with serum ALT less than twice ULN and high HBV-DNA levels in Indonesia.

OBJECTIVE: To study the prevalence of significant hepatic histopathology in chronic hepatitis B (CHB) patients with alanine aminotransferase (ALT) ≤ twice upper limit of normal (ULN) and its association with age, HBeAg status, hepatitis B virus (HBV)-DNA level and viral genotype. METHODS: A prospective study was conducted over a 3-year period in treatment-naive CHB patients with ALT ≤ twice ULN. Patients with a history of acute flare hepatitis, use of alcohol and hepatotoxic drugs, hepatitis C, hepatitis D and human immunodeficiency virus (HIV) co-infection were excluded from the study. Hepatic histopathology was assessed according to the METAVIR scoring system. RESULTS: A total of 145 patients were recruited, 81 (55.9%) of whom were male. The patients' mean age was 41.50 ± 10.74 years (range 16-70 years). Significant hepatic inflammation was found in 59.3% of these patients, and significant hepatic fibrosis was found in 62.1%, the latter being associated with hepatitis B e antigen status, ALT levels and serum HBV-DNA, but not with their age group or viral genotype. Significant hepatic fibrosis was found in 24 of 35 CHB patients (68.6%) who were previously considered in an immunotolerance phase. CONCLUSIONS: The prevalence of significant hepatic histopathology in CHB patients with serum ALT levels ≤ twice ULN is high. Delayed antiviral treatment can be harmful.
