RESUMO
INTRODUCTION: Cytarabine (ARA-C) is an antimetabolite agent used especially in the treatment of hematologic malignancies. Infusion reactions have an important place among the side effects that may occur due to treatment. Clinical findings of infusion reactions resemble allergic reactions. CASE REPORT: 47-year-old male patient with a diagnosis of B-cell Acute Lymphoblastic Leukaemia developed infusion reaction during ARA-C treatment. MANAGEMENT & OUTCOME: There was no alternative treatment option for his existing malignant disease, we decided ARA-C desensitization. DISCUSSION: We would like to describe a successful desensitization protocol in an adult patient who experienced a reaction during ARA-C infusion.

BACKGROUND AND AIMS: A few case reports of autoimmune hepatitis-like liver injury have been reported after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. We evaluated clinical features, treatment response and outcomes of liver injury following SARS-CoV-2 vaccination in a large case series. APPROACH AND RESULTS: We collected data from cases in 18 countries. The type of liver injury was assessed with the R-value. The study population was categorized according to features of immune-mediated hepatitis (positive autoantibodies and elevated immunoglobulin G levels) and corticosteroid therapy for the liver injury. We identified 87 patients (63%, female), median age 48 (range: 18-79) years at presentation. Liver injury was diagnosed a median 15 (range: 3-65) days after vaccination. Fifty-one cases (59%) were attributed to the Pfizer-BioNTech (BNT162b2) vaccine, 20 (23%) cases to the Oxford-AstraZeneca (ChAdOX1 nCoV-19) vaccine and 16 (18%) cases to the Moderna (mRNA-1273) vaccine. The liver injury was predominantly hepatocellular (84%) and 57% of patients showed features of immune-mediated hepatitis. Corticosteroids were given to 46 (53%) patients, more often for grade 3-4 liver injury than for grade 1-2 liver injury (88.9% vs. 43.5%, p = 0.001) and more often for patients with than without immune-mediated hepatitis (71.1% vs. 38.2%, p = 0.003). All patients showed resolution of liver injury except for one man (1.1%) who developed liver failure and underwent liver transplantation. Steroid therapy was withdrawn during the observation period in 12 (26%) patients after complete biochemical resolution. None had a relapse during follow-up. CONCLUSIONS: SARS-CoV-2 vaccination can be associated with liver injury. Corticosteroid therapy may be beneficial in those with immune-mediated features or severe hepatitis. Outcome was generally favorable, but vaccine-associated liver injury led to fulminant liver failure in one patient.

BACKGROUND: Data regarding outcome of Coronavirus disease 2019 (COVID-19) in vaccinated patients with autoimmune hepatitis (AIH) are lacking. We evaluated the outcome of COVID-19 in AIH patients who received at least one dose of Pfizer- BioNTech (BNT162b2), Moderna (mRNA-1273) or AstraZeneca (ChAdOx1-S) vaccine. PATIENTS AND METHODS: We performed a retrospective study on AIH patients with COVID-19. The outcomes of AIH patients who had acute respiratory syndrome coronavirus 2 (SARS-CoV-2) breakthrough infection after at least one dose of COVID-19 vaccine were compared to unvaccinated patients with AIH. COVID-19 outcome was classified according to clinical state during the disease course as: (i) no hospitalization, (ii) hospitalization without oxygen supplementation, (iii) hospitalization with oxygen supplementation by nasal cannula or mask, (iv) intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v) ICU admission with invasive mechanical ventilation or (vi) death, and data was analyzed using ordinal logistic regression. RESULTS: We included 413 (258 unvaccinated and 155 vaccinated) patients (81%, female) with a median age of 52 (range: 17-85) years at COVID-19 diagnosis. The rates of hospitalization were (36.4% vs. 14.2%), need for any supplemental oxygen (29.5% vs. 9%) and mortality (7% vs. 0.6%) in unvaccinated and vaccinated AIH patients with COVID-19. Having received at least one dose of SARS-CoV-2 vaccine was associated with a significantly lower risk of worse COVID-19 severity, after adjusting for age, sex, comorbidities and presence of cirrhosis (adjusted odds ratio [aOR] 0.18, 95% confidence interval [CI], 0.10-0.31). Overall, vaccination against SARS-CoV-2 was associated with a significantly lower risk of mortality from COVID-19 (aOR 0.20, 95% CI 0.11-0.35). CONCLUSIONS: SARS-CoV-2 vaccination significantly reduced the risk of COVID-19 severity and mortality in patients with AIH.

BACKGROUND AND AIMS: Data regarding outcome of COVID-19 in patients with autoimmune hepatitis (AIH) are lacking. APPROACH AND RESULTS: We performed a retrospective study on patients with AIH and COVID-19 from 34 centers in Europe and the Americas. We analyzed factors associated with severe COVID-19 outcomes, defined as the need for mechanical ventilation, intensive care admission, and/or death. The outcomes of patients with AIH were compared to a propensity score-matched cohort of patients without AIH but with chronic liver diseases (CLD) and COVID-19. The frequency and clinical significance of new-onset liver injury (alanine aminotransferase > 2 × the upper limit of normal) during COVID-19 was also evaluated. We included 110 patients with AIH (80% female) with a median age of 49 (range, 18-85) years at COVID-19 diagnosis. New-onset liver injury was observed in 37.1% (33/89) of the patients. Use of antivirals was associated with liver injury (P = 0.041; OR, 3.36; 95% CI, 1.05-10.78), while continued immunosuppression during COVID-19 was associated with a lower rate of liver injury (P = 0.009; OR, 0.26; 95% CI, 0.09-0.71). The rates of severe COVID-19 (15.5% versus 20.2%, P = 0.231) and all-cause mortality (10% versus 11.5%, P = 0.852) were not different between AIH and non-AIH CLD. Cirrhosis was an independent predictor of severe COVID-19 in patients with AIH (P < 0.001; OR, 17.46; 95% CI, 4.22-72.13). Continuation of immunosuppression or presence of liver injury during COVID-19 was not associated with severe COVID-19. CONCLUSIONS: This international, multicenter study reveals that patients with AIH were not at risk for worse outcomes with COVID-19 than other causes of CLD. Cirrhosis was the strongest predictor for severe COVID-19 in patients with AIH. Maintenance of immunosuppression during COVID-19 was not associated with increased risk for severe COVID-19 but did lower the risk for new-onset liver injury during COVID-19.

BACKGROUND: We investigated associations between baseline use of immunosuppressive drugs and severity of Coronavirus Disease 2019 (COVID-19) in autoimmune hepatitis (AIH). PATIENTS AND METHODS: Data of AIH patients with laboratory confirmed COVID-19 were retrospectively collected from 15 countries. The outcomes of AIH patients who were on immunosuppression at the time of COVID-19 were compared to patients who were not on AIH medication. The clinical courses of COVID-19 were classified as (i)-no hospitalization, (ii)-hospitalization without oxygen supplementation, (iii)-hospitalization with oxygen supplementation by nasal cannula or mask, (iv)-intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v)-ICU admission with invasive mechanical ventilation or (vi)-death and analysed using ordinal logistic regression. RESULTS: We included 254 AIH patients (79.5%, female) with a median age of 50 (range, 17-85) years. At the onset of COVID-19, 234 patients (92.1%) were on treatment with glucocorticoids (n = 156), thiopurines (n = 151), mycophenolate mofetil (n = 22) or tacrolimus (n = 16), alone or in combinations. Overall, 94 (37%) patients were hospitalized and 18 (7.1%) patients died. Use of systemic glucocorticoids (adjusted odds ratio [aOR] 4.73, 95% CI 1.12-25.89) and thiopurines (aOR 4.78, 95% CI 1.33-23.50) for AIH was associated with worse COVID-19 severity, after adjusting for age-sex, comorbidities and presence of cirrhosis. Baseline treatment with mycophenolate mofetil (aOR 3.56, 95% CI 0.76-20.56) and tacrolimus (aOR 4.09, 95% CI 0.69-27.00) were also associated with more severe COVID-19 courses in a smaller subset of treated patients. CONCLUSION: Baseline treatment with systemic glucocorticoids or thiopurines prior to the onset of COVID-19 was significantly associated with COVID-19 severity in patients with AIH.

The liver is the main organ for metabolic and detoxification reactions in the body. Therefore, its diseases can be associated with both metabolic disorders, such as insulin resistance, obesity, diabetes, or dyslipidemia, and exogenous insults such as drugs, xenobiotics, or alcohol. Indeed, lifestyle changes are the primary approaches for the prevention and treatment of liver diseases. Since ancient times, herbals have also been used for preventive and therapeutic purposes, because of their anti-apoptotic, anti-inflammatory, and antioxidant effects. Here, the literature was reviewed for potential therapeutic effects of plants and their compounds by including in vitro and in vivo studies, as well as clinical trials. Although the available data imply some beneficial roles of herbals on the liver, the indications and posology of specific plants need to be clarified through multicenter, randomized clinical trials.
RESUMO
INTRODUCTION: Anaphylaxis is a severe and life-threatening systemic hypersensitivity reaction. The most frequently encountered causes are foods, drugs, and bee venom, but anaphylaxis may also occur idiopathically. Paradoxical vocal cord movement (PVCM), is a cause of upper airway obstruction due to abnormal adduction of vocal cords during inspiration and, to some degree on expiration. It may be misdiagnosed as asthma or anaphylaxis, and there may be delays in diagnosis. CASE REPORT: We present a 20-year-old male patient with coexistence of urticaria and stridor findings who was evaluated and treated as having idiopathic anaphylaxis but then was diagnosed with PVCM after recurrence of stridor attacks. CONCLUSION: It is useful to bear the diagnosis of PVCM in mind in patients with recurrent and unexplained stridor or in patients with stridor that does not improve despite treatment for another diagnosis such as anaphylaxis. This way, administration of epinephrine, high-dose corticosteroids and interventions such as intubation or tracheostomy can be avoided.
RESUMO
BACKGROUND/AIMS: Inborn errors of immunity (IEI) may associate with autoimmune diseases, including autoimmune liver diseases (AILD). However, both the IEI frequency and secondary effects of immunosuppressives are unknown in patients with AILD due to the lack of data. We aimed to evaluate the ratio of IEI in AILD. MATERIALS AND METHODS: A total of 82 patients with AILD (39 autoimmune hepatitis, 32 primary biliary cholangitis, 7 variant syndromes (VS), and 4 primary sclerosing cholangitis patients) were included in this single-center, cross-sectional, and descriptive study. The patients were evaluated and classified according to diagnostic criteria for IEI. RESULTS: Out of 82 patients with AILD, female/male ratio was 3.6. Median age of diagnosis of AILD was 45 years. We diagnosed 15 (18%) patients with immunodeficiency (ID). Inborn errors of immunity ratio was highest in VS patient group (29%). Out of 15 patients with ID, 4 (4.8%) patients had common variable immunodeficiency, 4 (4.8%) had partial immunoglobulin A deficiency, 4 (4.8%) had selective immunoglobulin M deficiency, and 3 (3.6%) had combined immunodeficiency. CONCLUSION: We detect ID in about one-fifth of the patients with AILD. The present study showed a significant risk of IEI that is blurred by the shadow of immune suppressive treatments. We suggest that the AILD patients with ID will benefit from the individualized and targeted therapeutic options used in IEI. Further research with larger patient groups and long-term follow-up are desperately needed to elucidate the diagnostic, therapeutic, and prognostic impacts of IEI-related individualized therapy on AILD patients.

Background and Aim: This study aimed to identify the indications for liver transplantation (LT) based on underlying etiology and to characterize the patients who underwent LT. Materials and Methods: We conducted a multicenter cross-sectional observational study across 11 tertiary centers in Turkiye from 2010 to 2020. The study included 5,080 adult patients. Results: The mean age of patients was 50.3±15.2 years, with a predominance of female patients (70%). Chronic viral hepatitis (46%) was the leading etiological factor, with Hepatitis B virus infection at 35%, followed by cryptogenic cirrhosis (24%), Hepatitis C virus infection (8%), and alcohol-related liver disease (ALD) (6%). Post-2015, there was a significant increase in both the number of liver transplants and the proportion of living donor liver transplants (p<0.001). A comparative analysis of patient characteristics before and after 2015 showed a significant decline in viral hepatitis-related LT (p<0.001), whereas fatty liver disease-related LT significantly increased (p<0.001). Conclusion: Chronic viral hepatitis continues to be the primary indication for LT in Turkiye. However, the proportions of non-alcoholic fatty liver disease (NAFLD) and ALD-related LT have seen an upward trend over the years.
RESUMO
Primary mutations conferring hepatitis B virus (HBV) antiviral resistance and associated secondary/compensatory mutations were investigated in this study by DNA sequencing (SEQ) and two commercial Line Probe Assays (LiPAs) (Inno-Lipa HBV DRv2 and Inno-Lipa HBV DRv3, Innogenetics, Belgium). A total of 71 subjects under follow-up for chronic hepatitis B and receiving lamivudine (LVD) therapy for one year or longer at the Hacettepe University Faculty of Medicine, Department of Internal Medicine, Gastroenterology Unit were included in the study with informed consent. Male to female ratio and mean age was noted as 47/24 and 43 ± 15.8 (age range: 13-71) years, respectively. Twenty samples with low HBV DNA levels (mean: 204.6 IU/ml) could not be interpreted by SEQ due to insufficient amplification. All samples with a positive consensus PCR were further analysed via LiPAs, as directed by the manufacturer. Thus a total of 51 and 56 samples could be evaluated via SEQ and LiPA assays, respectively. In 13 of the 51 (25.5%) samples by SEQ and in 9 of 56 (16%) samples by LiPAs, primary and compensatory mutations associated with resistance were identified. Multiple mutations that comprise L180M + M204I in four and L180M + M204V in one sample and single mutations (M204I) in three samples were identified by SEQ. In one sample which had multiple mutations associated with LVD resistance single mutations (S202G, N236T) associated with entecavir resistance and in two other such samples mutations associated with adefovir resistance were detected by SEQ. Also, in three samples amino acid substitution at position rt215 (QÆS) as alone and in one sample with multiple mutations were observed via SEQ. In five of nine samples primary and compensatory multiple mutations (L180M + M204I in one sample, L80I + L180M + M204I in two samples, L80I/V + M204I in one sample) and primary single mutations associated with LVD resistance (M204I/V) in four samples were detected by Inno-Lipa HBV DRv2. Two different mutations (G202, ILFM184) were observed in two samples with multiple mutations associated LVD resistance via Inno-Lipa HBV DRv3. However, mutation at position rt184 was evaluated as a weak positive. Any mutation associated with adefovir resistance was not detected by LiPA. As a result, SEQ and LiPAs displayed comparable performances for the detection of HBV drug resistance mutations. We suggested that for the evaluation of discordant results, it should be better to test consecutive serum samples.

The liver has a complex vascular anatomy with a unique dual blood supply. Clinical conditions of the liver vary widely and include disorders originating in the vascular and biliary systems as well as the parenchyma. In most vascular disorders, the effects on the liver are generally subclinical because of its abundant blood supply. However, early diagnosis of such vascular diseases can significantly reduce patient morbidity and mortality. Because imaging findings of vascular disease are not always readily apparent, diagnosis can be difficult. Computed tomography angiography is an excellent imaging modality for visualizing the vascular anatomy of patients for treatment planning. In this review article, we focus on the vascular anatomy of the liver and the imaging findings in some acute hepatic vascular diseases.
RESUMO
The liver is the front line organ of the immune system. The liver contains the largest collection of phagocytic cells in the body that detect both pathogens that enter through the gut and endogenously produced antigens. This is possible by the highly developed differentiation capacity of the liver immune system between self-antigens or non-self-antigens, such as food antigens or pathogens. As an immune active organ, the liver functions as a gatekeeping barrier from the outside world, and it can create a rapid and strong immune response, under unfavorable conditions. However, the liver's assumed immune status is anti-inflammatory or immuno-tolerant. Dynamic interactions between the numerous populations of immune cells in the liver are key for maintaining the delicate balance between immune screening and immune tolerance. The anatomical structure of the liver can facilitate the preparation of lymphocytes, modulate the immune response against hepatotropic pathogens, and contribute to some of its unique immunological properties, particularly its capacity to induce antigen-specific tolerance. Since liver sinusoidal endothelial cell is fenestrated and lacks a basement membrane, circulating lymphocytes can closely contact with antigens, displayed by endothelial cells, Kupffer cells, and dendritic cells while passing through the sinusoids. Loss of immune tolerance, leading to an autoaggressive immune response in the liver, if not controlled, can lead to the induction of autoimmune or autoinflammatory diseases. This review mentions the unique features of liver immunity, and dysregulated immune responses in patients with autoimmune liver diseases who have a close association with inborn errors of immunity have also been the emphases.
RESUMO
Nonalcoholic fatty liver disease (NAFLD) is a multisystem disease and is significantly associated with obesity, insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease. NAFLD has become the most prevalent chronic liver disease in Western countries, and the proportion of NAFLD-related cirrhosis among patients on liver transplantation waiting lists has increased. In light of the accumulated data about NAFLD, and to provide a common approach with multi-disciplines dealing with the subject, it has become necessary to create new guidance for diagnosing and treating NAFLD. This guidance was prepared following an interdisciplinary study under the leadership of the Turkish Association for the Study of the Liver (TASL), Fatty Liver Special Interest Group. This new TASL Guidance is a practical application guide on NAFLD and was prepared to standardize the clinical approach to diagnosing and treating NAFLD patients. This guidance reflects many advances in the field of NAFLD. The proposals in this guidance are meant to aid decision-making in clinical practice. The guidance is primarily intended for gastroenterology, endocrinology, metabolism diseases, cardiology, internal medicine, pediatric specialists, and family medicine specialists.
RESUMO
OBJECTIVE: To identify changes in hepatitis B epidemiology after the implementation of the nationwide vaccination program in Turkey, hepatitis B virus (HBV) and related tests performed over a period of 11 years (2000-2010) at a reference centre were retrospectively overviewed and statistically analysed for trends. RESULTS: Assay results for Hepatitis B surface antigen (HBsAg) and e antigen (HBeAg), Anti-HBs, Anti-HBe, Anti-HBc immunoglobulins and HBV DNA as well as aspartate aminotransferase (AST), alanine aminotransferase (ALT), gama-glutamyl transpeptidase (GGT) and alkaline phosphatase (AP) levels, obtained via standardized commercial assays were included in the analysis. Overall, a stable anti-HBs incidence (43.6%) and male predominance in infected individuals were noted. Total Anti-HBc was detected in 43.3% of the Anti-HBs reactive population, demonstrating that the immunity against HBV has still been acquired through virus exposure. An intermediate HBsAg seroprevalence of 6.0% was observed with a significant decrease from 12.3% to 5.0% from 2000 to 2010. Anti-HBe positive infections were more frequent than those with HBe antigenemia (77.1% vs. 18.5%) with a notable increase from 2000 to 2003. HBV DNA was detected in 23.6-25.6% with serological markers of viral replication and was more prevalent in HBeAg positive individuals in parallel with AST, ALT and GGT levels. Evidence for horizontal transfer as the major transmission route was revealed with a reduction of childhood HBV infections, attributable to the ongoing vaccination efforts.

OBJECTIVE: The aim of this study was to investigate the effects of abdominal massage on the severity of constipation, bowel function, and quality of life (QoL) in patients with functional chronic constipation in a randomized placebo-controlled design. METHODS: Seventy-four patients diagnosed with functional constipation according to the Rome IV diagnostic criteria were included. Patients were randomly assigned to the intervention group (abdominal massage plus lifestyle advice) or the control group (placebo therapeutic ultrasound plus lifestyle advice). Abdominal massage or placebo ultrasound was applied for 4 weeks. The primary outcome measure was the Constipation Severity Instrument score. Bowel diary data and the Patient Assessment of Constipation Quality of Life Questionnaire score were used as secondary outcome measures. Differences in outcome measures within and between groups were analyzed by repeated-measures analysis of variance. RESULTS: Although constipation severity, bowel function indicators (defecation frequency and duration and stool consistency), and QoL were found to improve significantly over time in both groups, improvements in both primary and secondary outcomes were much more significant in the abdominal massage group. In addition, group × time interaction effects were found to be significant for constipation severity, bowel function findings, and QoL. There were approximately 70% and 28% reductions in constipation severity, 56% and 38% improvement rates in QoL, and 70% and 43% increases in defecation frequency in the intervention and placebo groups, respectively. CONCLUSION: Abdominal massage should be one of the first-line conservative approaches in the management of functional chronic constipation. Further randomized placebo-controlled studies with long-term follow-up are needed. IMPACT: For functional constipation, which is a common gastrointestinal problem, abdominal massage should be considered as an option in first-line therapy because of its effect beyond the placebo effect. LAY SUMMARY: If you have functional constipation, your physical therapist may be able to provide abdominal massage to help reduce your symptoms.

BACKGROUND: Liver graft fibrosis affects long-term graft and patient survival in liver transplant recipients. Transient elastography and magnetic resonance elastography are widely used for the assessment of liver fibrosis in routine clinical practice, but are limited in liver transplant settings. The aims of the present study were to evaluate the accuracy of magnetic resonance elastography and transient elastograph in the assessment of liver fibrosis in liver transplant recipients, and to determine the recurrence rates of post-transplant hepatic steatosis and liver fibrosis. METHODS: A total of 126 consecutive liver transplant recipients were included. Magnetic resonance elastography and transient elastography were performed for to measure liver stiffness. RESULTS: The most common cause of liver transplantation was hepatitis B virus-induced cirrhosis (50%). The mean liver stiffness value with transient elastography was 6.1 ± 3.0 kPa, and the mean magnetic resonance elastography value was 2.7 ± 1.0 kPa. A significant positive correlation was found between magnetic resonance elastography and transient elastography in terms of liver stiffness measurement (r = 0.61, P < .001). Obesity and the underlying etiology of liver diseases did not have any significant negative effect on magnetic resonance elastography and transient elastography measurements. During the follow-up, the post-transplant recurrence rates of hepatic steatosis and hepatic fibrosis were 26% and 37%, respectively. The recurrence rates of post-transplant hepatic steatosis and liver fibrosis were slightly higher in recipients with non-alcoholic fatty liver disease-related cirrhosis than those with viral hepatitisrelated etiologies (44% vs 27%, P = .43; 44% vs 30%, P = .45, respectively). CONCLUSION: Magnetic resonance elastography and transient elastography are accurate in assessing liver fibrosis in the liver transplant setting. Obesity and the underlying etiology of primary liver disease do not influence the measurements.

BACKGROUND: Alpha 1 antitrypsin (AT) deficiency is a hereditary disorder leading to the defective defence system against neutrophil elastasis in lung and accumulation of insoluble heterodimer AT molecules in hepatocytes. Knowledge of the prevalence of AT deficiency in each country is important to organize the public health policy. The aim of this study is to determine the prevalence of AT deficiency in Turkish population and to define the cutoff value of AT level in serum to detect heterozygous AT deficient subjects. MATERIALS AND METHODS: Serum samples from 1,203 healthy blood donors were used, attending the Blood Bank of Hacettepe Medical Faculty. Isoelectric focusing method for determining PIM, PIS, and PIZ alleles and rate immune nephelometry for measuring the level of AT in serum were used. RESULTS: Out of 1,203 healthy blood donors enrolled, 1,164 (%96.8) had normal variant PI MM allelee, 9 (%0.7) PI MZ, 7 (%0.6) PI MS, 6 (%0.5) MF, and 17 (%1.4) PI M? (unidentified variants with existing standards). Most individuals (89.6%) with low AT level (cutoff <100 mg/dl) in serum were positive for PI MM allele. The cutoff value to investigate PI MZ was 100.5 mg/dl, which had PPV and NPV of 5.0 and 99.9%, respectively. AT deficiency is a rare hereditary disorder in asymptomatic healthy Turkish blood donors. Although the cutoff value of 100.5 mg/dl for AT level in serum was able to detect heterozygous AT deficiency in the healthy population, this finding should be conformed to case-control studies.

The presence of autoantibody positivity with an elevated ferritin level and high transferrin saturation can create a diagnostic dilemma. This report describes the challenging case of 38-year-old male patient who presented with new-onset diabetes, malaise, weight loss, dark-yellow skin discoloration, and splenomegaly. Initial laboratory tests revealed thrombocytopenia, leucopenia, an elevated unconjugated bilirubin level, and mildly elevated liver enzymes in a cholestatic pattern. Antinuclear antibody and anti-smooth muscle antibody findings were positive with titers of 1/160 and 1/320, respectively, along with hypergammaglobulinemia. The transferrin saturation value was 92% and the ferritin level was 498 µg/L. HFE gene mutation analysis revealed a C282Y heterozygote mutation, which is not diagnostic, but supported a diagnosis of hereditary hemochromatosis (HH). A liver biopsy is the most accurate way to differentiate autoimmune hepatitis from HH, and confirmed a diagnosis of HH. This case highlights the importance of paying close attention to all findings to avoid misdiagnosis and treatment which might result in dangerous outcomes. Additionally, in spite of a genetic test, a liver biopsy has great value as an important tool to determine an accurate diagnosis in patients with iron overload, especially in patients with concomitant autoantibody positivity.
