Hepatic tuberculosis (TB) is an uncommon extrapulmonary manifestation of tuberculosis. Hepatic TB is more common in immunocompromised patients, such as those on immunosuppressive medications or those with a human immunodeficiency virus (HIV) infection. Primary hepatic TB is rare, and liver involvement is often secondary to spreading from the lymphatics, portal vein, or hepatic artery. We report a case of hepatic TB in a patient on adalimumab for ankylosing spondylitis (AS).

Legionnaires\' disease is an atypical pneumonia caused by Legionella pneumophila. Legionella species are found in freshwater sources and are transmitted through inhalation of contaminated aerosols. Patients commonly present with fever, chills, and cough. However, in immunosuppressed patients or severe cases, the disease can lead to multiorgan failure. In recent years, the incidence of Legionnaires\' disease has drastically increased and unfortunately is commonly underdiagnosed. Gold-standard diagnosis is made through sputum cultures; however, urine Legionella antigen remains the most common test used for diagnosis. Goal-directed care includes antibiotics and supportive care. This case highlights a rare and unique presentation of Legionnaires\' disease presenting with an elevated 2:1 aspartate aminotransferase to alanine transaminase pattern, typically seen with alcoholic hepatitis.

BACKGROUND: Levamisole is less expensive and has a better toxicity profile compared to other steroid sparing agents used in nephrotic syndrome. It has a plasma half-life of 2.0 to 5.6 hours, but is conventionally administered on alternate days. We aimed to assess whether daily levamisole is safe and more effective than standard alternate-day therapy in maintaining remission in children with frequently relapsing or steroid-dependent nephrotic syndrome (FR/SDNS).
METHODS: An open-label randomized controlled trial was conducted in children with FR/SDNS. Group A received daily while Group B received alternate-day levamisole (2-3 mg/kg/dose) for 12 months. Prednisolone was tapered off by 3 months. Patients were monitored for relapses, further steroid requirement, and adverse effects.
RESULTS: A total of 190 children with FR/SDNS (94 in Group A and 96 in Group B) were analyzed. Sustained remission for 12 months was observed in 36% of Group A and 27% of Group B patients (p = 0.18). Numbers completing 12 months in the study were 67% in Group A and 56% in Group B (p = 0.13). Time to first relapse, persistent FR/SDNS, and withdrawal due to poor compliance were statistically similar in both groups, while relapse rate and cumulative steroid dosage were significantly lower in Group A compared to Group B (p = 0.03 and p = 0.02, respectively). The incidence of adverse effects was comparable in both groups, with reversible leucopenia and hepatic transaminitis being the commonest.
CONCLUSIONS: Daily levamisole therapy was not superior to alternate-day therapy in maintaining sustained remission over 12 months. Nevertheless, relapse rate and cumulative steroid dosage were significantly lower without increased adverse effects.

Tejocote, a product of the hawthorn tree and a common staple of Hispanic culinary practices and traditional medicine, has recently gained traction in the United States and Mexico as a means to achieve rapid effortless weight loss. This herbal supplement has largely evaded regulation by governing bodies in both countries despite documentation of several potentially serious adverse effects associated with its use. The present report describes the case of a middle-aged Hispanic female who ingested Tejocote with famotidine and presented with acute gastrointestinal symptoms and transaminitis, an unexpected symptom that warrants further investigation.

Ulcerative colitis (UC) is an autoimmune disease associated with both intestinal and extraintestinal manifestations. The latter may include heart complications, such as myopericarditis leading to life-threatening arrythmias. Nowadays, UC is commonly treated with biologic medications and infliximab is the first line therapy in an outpatient setting, while it is also used as rescue therapy in acute severe UC. However, it has been associated with severe immunosuppression, cytomegalovirus (CMV) reactivation and drug-induced hepatitis. We report a case of UC flare in a biologic naïve patient admitted with myopericarditis, which was further complicated by positive CMV biopsies and infliximab-induced transaminitis.
CONCLUSIONS: In acute inflammatory bowel disease (IBD) flare presentation with tachycardia and chest pain, an underlying myocardial injury should be investigated.Mucosal healing should be evaluated endoscopically in cases of partial response to biologics.Both cytomegalovirus (CMV) infection and infliximab-induced liver injury may lead to acute hepatitis.

Sickle cell disease is a hemoglobinopathy often complicated by painful vaso-occlusive episodes, acute chest syndrome, stroke, and myocardial infarction. Sickle cell intrahepatic cholestasis (SCIC) is a rare and potentially fatal complication of sickle cell disease. SCIC is thought to involve progressive hepatic injury due to sickling within sinusoids. We present the case of a young patient with SCIC and acute liver failure, requiring prompt treatment with exchange transfusion. Our case describes features that should raise suspicion for hepatic failure in SCIC and highlights exchange transfusion as a successful management approach in similar patients with an otherwise high risk of mortality.

Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease that occurs in a bimodal age distribution in the second and fifth-sixth decade of life. The disease is more prevalent in females and presents with variable clinical manifestations ranging from being asymptomatic to acute liver failure. AIH is often overlooked and not worked up in elderly patients who present with liver failure. This can lead to increased morbidity and mortality in elderly patients. AIH should be considered as a differential diagnosis in patients who present with elevated transaminases regardless of age or gender as early recognition and treatment leads to improved outcomes. In this article, we present a unique case of AIH in a male patient in his eighth decade of life who presented with acute liver failure without any obvious cause and had no history of autoimmune diseases.

BACKGROUND: Chronic hepatitis B (CHB) is well-known as a major risk for liver cirrhosis and hepatocellular carcinoma (HCC). The A1762T/G1764A double mutation in the hepatitis B virus genome affects the production of HBe antigen and is established as a predictive marker for progression to HCC. Thus, this study aimed to investigate the prevalence and clinical significance of the mutation in Thai CHB patients.
METHODS:  A cross-sectional study was conducted in 78 Thai CHB patients who were assessed for hepatitis B profiles, HBsAg, HBeAg and anti-HBeAg, transaminitis, liver fibrosis defined by FIB-4 (FIB-4) score and AST to platelet ratio index (APRI), alpha-fetoprotein (AFP) and active hepatitis B status. HBV A1762T/G1764A mutation was examined by SYBR Green I Real-time PCR. Chi-square and Mann-Whiney U tests were performed to determine the association between the mutation and variables.
RESULTS: The prevalence of patients infected with the A1762T/G1764A mutation was 44.9%. The mutation was associated with HBeAg status (p=0.027) and HBsAg levels (p=0.008), transaminitis (p=0.011), and active hepatitis B (p=0.037), but not liver fibrosis markers, FIB-4 score and APRI, and AFP. Binary logistic regression identified the mutation as a predictive factor of active hepatitis B (OR 3.5, 95%CI, 1.1-11.3, p=0.037). Patients infected with the mutant exhibited significantly higher levels of HBsAg (p=0.011) and HBV viral load (p=0.047), but lower levels of HBeAg (p=0.12) than those infected with the wild-type HBV.
CONCLUSIONS: The data indicate the high prevalence of the A1762T/G1764A mutation and its significant association with the severity of Thai CHB patients and the HBV mutation is proposed as a predictive marker of active hepatitis B status in CHB patients.

Drug-induced liver injury (DILI) is a common cause of transaminitis in pregnancy. A 34-year-old G3P2012 presented 3 weeks postpartum for preeclampsia with severe features. After receiving acute antihypertensive medications, she was discharged home with labetalol. She presented 5 months later with general malaise, scleral icterus, nausea, and mild right upper quadrant pain and found to have significantly elevated transaminitis. She had a negative infectious, autoimmune, biliary, and steatohepatitis workup. A liver biopsy was performed supporting the diagnosis of DILI. After patient self-discontinued labetalol, her hepatitis significantly improved. However, she developed chronic DILI and liver enzymes normalized during her subsequent pregnancy at 34 weeks. Patient\'s written consent was obtained for this case report. Chronic DILI secondary to labetalol use is a rare and potentially fatal condition that should be considered on the differential for transaminitis during pregnancy and postpartum period.

Objective  The four initial severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected pregnant women presenting at term gestation to our institution presented with transaminitis. Three of the four were diagnosed with intrahepatic cholestasis of pregnancy (IHCP). Growing evidence exists of an associated transaminitis in nonpregnant SARS-CoV-2 patients. However, there are limited data of hepatic involvement of SARS-CoV-2 in pregnancy, and no previous studies have assessed the association with IHCP in patients with coronavirus disease 2019 (COVID-19). Study Design  This was a retrospective, single-center case series of four consecutive pregnant women with a positive result for SARS-CoV-2 presenting with transaminitis in third trimester. Results  The clinical courses of four pregnant women with COVID-19 and transaminitis, three of four of whom were diagnosed with IHCP, are described. Testing for SARS-CoV-2 was done through a reverse transcription polymerase chain reaction test of a nasopharyngeal swab. Conclusion  As we await larger studies ascertaining the incidence of IHCP in SARS-CoV-2, this prevalence highlights the importance of diagnosing IHCP among women with COVID-19 as a potential etiology of transaminitis, as IHCP risks may be ameliorated with earlier delivery. Moreover, delineating a hepatobiliary association in pregnancy may provide further information about the mechanism of liver impairment in SARS-CoV-2 in all patients.
