Harper LJ, Farver CF, Yadav R, Culver DA. A framework for exclusion of alternative diagnoses in sarcoidosis. J Autoimmun 2024:103288.

Abstract
Sarcoidosis is a multisystem granulomatous syndrome that arises from a persistent immune response to a triggering antigen(s). There is no "gold standard" test or algorithm for the diagnosis of sarcoidosis, making the diagnosis one of exclusion. The presentation of the disease varies substantially between individuals, in both the number of organs involved, and the manifestations seen in individual organs. These qualities dictate that health care providers diagnosing sarcoidosis must consider a wide range of possible alternative diagnoses, from across a range of presentations and medical specialties (infectious, inflammatory, cardiac, neurologic). Current guideline-based diagnosis of sarcoidosis recommends fulfillment of three criteria: 1) compatible clinical presentation and/or imaging 2) demonstration of granulomatous inflammation by biopsy (when possible) and, 3) exclusion of alternative causes, but do not provide guidance on standardized strategies for exclusion of alternative diagnoses. In this review, we provide a summary of the most common differential diagnoses for sarcoidosis involvement of lung, eye, skin, central nervous system, heart, liver, and kidney. We then propose a framework for testing to exclude alternative diagnoses based on pretest probability of sarcoidosis, defined as high (typical findings with sarcoidosis involvement confirmed in another organ), moderate (typical findings in a single organ), or low (atypical/findings suggesting of an alternative diagnosis). This work highlights the need for informed and careful exclusion of alternative diagnoses in sarcoidosis.

Abstract
A 45-year-old man who was regularly followed up for Crohn's disease (CD) and maintained clinical remission with vedolizumab (VDZ). At 37 years old, he was diagnosed CD from longitudinal ulcers in the distal ileum by balloon-assisted enteroscopy (BAE). During the follow-up, liver enzyme elevation, splenomegaly and thrombocytopenia were in progress. Esophagogastric varices suggested chronic liver disease and portal hypertension. Magnetic resonance elastography (MRE) showed liver stiffness of 3.4 kPa and proton density fat fraction (PDFF) of 1.86%. He was diagnosed with granulomatous hepatitis based on a liver biopsy. The hepatic venous pressure gradient (HVPG) was mildly elevated at 7 mmHg, consistent with the pre-sinusoidal portal hypertension due to granulomatous hepatitis. We report a rare case with granulomatous hepatitis diagnosed from liver injury and portal hypertension, despite the stable intestinal symptoms of CD.

Pathol Res Pract 2024; 255:155201. [PMID: 38367601 DOI: 10.1016/j.prp.2024.155201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 01/31/2024] [Accepted: 02/05/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND Liver granulomas have always been a diagnostic challenge for pathologists. They have been described in up to 15% of liver biopsies and can also be seen in liver allograft biopsy specimens, but there is a paucity of information regarding the prevalence and associated etiologic factors of granulomas in liver transplanted patients. The aim of this study is to shed light on the etiology of liver granulomas. METHODS Liver biopsies from liver transplanted patients, in the period from 01.01.2011 - 01.05.2017, were examined. We registered the histo-morphological characteristics and clinicopathological data of all biopsies and performed next-generation sequencing (NGS) to detect possible pathogens (bacteria, fungi, and parasites) in the biopsies containing granulomas. RESULTS We reviewed a total of 400 liver biopsies from 217 liver transplant patients. Of these, 131 liver biopsies (32.8%) from 98 patients (45.2%) revealed granulomas. Most were epithelioid granulomas located parenchymal and were detected in 115 (87.7%) biopsies. We also identified 10 cases (7.6%) with both lobular and portal granulomas and six biopsies (4.5%) with portal granulomas alone. In 54 biopsies (41.2%), granulomas were found in biopsies with acute cellular rejection (ACR). Fifty (51%) patients with granulomas underwent liver transplantation for autoimmune-related end-stage liver disease (AILD). The granulomas were found most frequently in the first six months after transplantation, where patients also more often were biopsied. NGS analysis did not reveal any potential infectious agent, and no significant differences were observed in the microbiological diversity (microbiome) between clinical- and granuloma characteristics concerning bacteria, fungi, and parasites. CONCLUSION Our study confirmed that granulomas are frequently seen in liver allograft biopsy specimens, and most often localized in the parenchyma, occurring in the first post-transplant period in patients with AILD, and often seen simultaneously with episodes of ACR. Neither a specific microbiological etiological agent nor a consistent microbiome was detected in any case.

Abstract
A 50-year-old female who presented to our hospital for recurrent diarrhea was found to have worsening aminotransferase and alkaline phosphatase levels. Workup revealed lymphadenopathy and hepatomegaly prompting a biopsy of the liver and axillary lymph node, confirming a diagnosis of hepatic sarcoidosis. Our patient later developed cutaneous sarcoidosis. She is currently asymptomatic and is followed by gastroenterology, pulmonary, and dermatology. Recognition of extrapulmonary manifestations of sarcoidosis is important for proper management of patients. Treatment often requires a multidisciplinary approach when more than one organ system is involved.

Abstract
Alkaline phosphatases (ALPs) are a group of isoenzymes, situated on the external layer of the cell membrane; they catalyze the hydrolysis of organic phosphate esters present in the extracellular space. Zinc and magnesium are significant co-factors for the biological activity of these enzymes. Although ALPs are available in various body tissues and have distinct physiochemical properties, they are true isoenzymes since they catalyze a similar reaction. In the liver, ALP is cytosolic and present in the canalicular membrane of the hepatocytes. ALPs are available in placenta, ileal mucosa, kidney, bone, and liver. However, most of the ALPs in serum (over 80%) are delivered from liver and bone and in more modest quantities from the intestines. Despite the fact that alkaline phosphatases are found in numerous tissues all through the body, their exact physiological function remains largely unknown.

Abstract
Introduction Sarcoidosis is a systemic granulomatosis of unknown etiology, characterized by the presence of immune granulomas. Liver damage is a relatively common extra-pulmonary manifestation, occurring in 3.6-30% of cases. Some patients can develop symptomatic portal hypertension (PH). Few series have evaluated the prognosis of symptomatic PH as well as the efficacy and safety of specific treatment on this complication. Methods This is a multicenter retrospective study of cases of histologically proven hepatic sarcoidosis with symptomatic PH (ascites, digestive hemorrhage) and/or hepatic encephalopathy. Demographic characteristics, comorbidities, clinical manifestations of sarcoidosis, biological data, imaging study of the liver, treatment, and clinical outcomes were collected. Results Twelve patients were identified, with a mean follow-up of 140 months. The M/F ratio was 1 and Caucasian origin was the most represented (75%). Seven patients presented with hepatic comorbidities: metabolic syndrome, chronic alcoholism or chronic viral hepatitis. Apart from hepatic involvement, mediastino-pulmonary involvement was the most common followed by osteoarticular and skin. Liver damage was inaugural in two thirds of cases. Nine patients developed ascites, six presented esophageal varices complicated by gastrointestinal bleeding. Three patients presented with both ascites and variceal bleeding. One case of hepatic encephalopathy was observed. Five patients presented signs of hepatocellular insufficiency during follow-up, of whom three had hepatic comorbidities. Eight out of 12 patients required second-line treatment after failure of corticosteroids, three patients underwent ligation of esophageal varices but with recurrent digestive bleeding in all cases. Two patients benefited from a transjugular intrahepatic portosystemic shunt (TIPS), also with poor result. At the end of follow-up, five patients were alive and seven patients died. Two patients received a liver transplant, with good result and without recurrence of sarcoidosis on the transplant thereafter. Two patients had quiet sarcoidosis on low dose of corticosteroids and one patient was lost to follow-up. Conclusion Symptomatic PH related to hepatic sarcoidosis is a severe complication, with high morbidity and mortality, and frequent failure of specific treatments of PH. Early management of these patients, with detection of hepatic comorbidities seems important. In case of therapeutic failure, liver transplantation is an option to consider.

Abstract
Hepatic granulomas can have various causes and their detection requires a systematic diagnostic evaluation. First, identification of risk factors for granulomatous diseases and the exclusion of extrahepatic organ manifestation are necessary. Laboratory investigations and serological screening for the most common underlying diseases of liver granulomas in Germany, such as primary biliary cholangitis (PBC), sarcoidosis and infectious causes (primarily tuberculosis and hepatitis C infections), are recommended. A liver biopsy is essential for confirming the diagnosis, whereby a minilaparoscopically guided tissue sampling offers many advantages, such as the macroscopic detection of granulomas on the liver surface, on the peritoneum or on the spleen. Whether the detection of hepatic granulomas results in a therapeutic consequence, depends decisively on the underlying primary disease. If hepatic granulomas are present without concomitant liver parenchymal damage or other manifestations that would make treatment necessary, a watch and wait approach under close clinical and laboratory monitoring is sufficient. If liver values increase or in cases of hepatic parenchymal damage, urgent treatment of the underlying disease is indicated.

Abstract
We herein report a case of coagulation necrosis with granulation and eosinophilic infiltration of the liver. A 37-year-old woman was diagnosed with a new mass lesion in the liver 1 month after breast cancer surgery and admitted for a further examination. Because the tumor occurred immediately after surgery, it was considered essential to determine whether or not it was a metastatic liver tumor from breast cancer. A percutaneous liver tumor biopsy revealed eosinophilic granuloma of the liver, which is considered to have a high possibility of visceral larva migrans with suspected gnathostomiasis infection. A detailed medical history and histological diagnosis are important for making a differential diagnosis.

Abstract
Vibrio parahaemolyticus is a gram-negative halophilic bacterium responsible for gastrointestinal infection in human and vibriosis in aquatic animals. The thermostable direct hemolysin (tdh), tdh-related hemolysin (trh) and thermolabile hemolysin (tlh) positive strains of V. parahaemolyticus were identified from brackishwater aquaculture farms of West Bengal and Andhra Pradesh, India. Moreover, the presence of other virulent genes like vcrD1, vopD, vp1680 under type three secretion system 1 (T3SS1) and vcrD2 vopD2, vopB2, vopC2 under type three secretion system 2 (T3SS2) were detected in tdh positive strain of V. parahaemolyticus. Furthermore, the study revealed that the tdh and trh positive isolates were resistant to β-lactam antibiotics and were able to lyse more than 95% of human Red Blood Cells (RBCs). In addition, both the isolates showed high cytotoxicity in Human Embryonic Kidney (HEK) cell line compared to tlh positive strain. Additionally, intraperitoneal and oral administration of tdh and trh positive strain of V. parahaemolyticus in Indian Major Carp, Labeo rohita caused 100% mortality at the level of 2.0 × 108 CFU ml-1 and 1.6 × 108 CFU ml-1, respectively. In contrast, only 10% mortality was observed in the case of tlh positive strain at the level of 2.5× 108 CFU ml-1. The histopathological changes like infiltration of blood cells and degenerated hepatic tissue in the liver of L. rohita were observed after the experimental challenge. The changes like degeneration of glomeruli, necrosis of renal tubules and Bowman's capsule were observed in the kidney section. Ragged, irregular shaped villi and necrosis of the villus were observed in the intestinal lumen. Overall, the study demonstrates that isolated V. parahaemolyticus is a potent aquatic microbial pathogen. Additionally, as V. parahaemolyticus is also a human pathogen and might pose a threat to the human population, proper management strategies are required to prevent the possible occurrence of disease.

Abstract
INTRODUCTION Sarcoidosis is a systemic granulomatous disease, characterized by the formation of non-necrotizing granulomas. Even though granulomas are frequently found in liver biopsy, related symptoms rarely occur. In the current article, a case report is pictured to increase the knowledge on portal hypertension in hepatic sarcoidosis. CLINICAL SITUATION A 62-year-old female was diagnosed with variceal bleeding for which elastic banding was performed. The patient was admitted to the intensive care unit (ICU) as the bleeding persisted and she evolved in hemorrhagic shock. Liver ultrasound detected nodular hepatomegaly and partial portal thrombosis. Chest CT showed diffuse hilar adenopathies and interstitial micronodular lesion. Finally, PET-CT detected metabolic active liver, bone marrow, and upper and lower diaphragmatic adenopathies. CLINICAL RESOLUTION Multidisciplinary discussion brought major advantages in rapid diagnosis and prompt effective treatment. Cirrhosis was diagnosed by liver nodularity on imaging and liver biopsy. Sarcoidosis diagnosis was supported by the biopsies of liver and lymph node, which yielded non-caseating granulomas infiltration. Chest CT scan and PET-CT were also consistent with this diagnosis. The complementary analysis excluded differential diagnosis. The patient was treated with high-dose methylprednisolone with notable clinical improvements and discharge from the ICU. CONCLUSION Hepatic sarcoidosis can present as life-threatening bleeding due to variceal bleeding caused by portal hypertension. Differential diagnosis is broad when hepatic sarcoidosis is suspected. Therefore, a multidisciplinary discussion is warranted. Anatomopathological examination of two potentially involved organs should be considered to make the appropriate diagnosis. Further studies are requested to investigate the pathophysiological mechanism of portal hypertension.

Abstract
The authors present the case of a female patient with a tumor of segment VII of the liver, which was postoperatively identified as a tuberculous granuloma. The patient was admitted for elective surgery for a liver tumor, which had been diagnosed a few months before. Computed tomography and nuclear magnetic resonance were performed, based on which focal nodular hyperplasia was suspected. Thirteen years prior to admission the patient had undergone a transurethral resection of superficial bladder carcinoma, followed by adjuvant intravesical Bacillus Calmette-Guérin (BCG-therapy). Upon surgery, segment VII of the liver was resected; postoperative course was uneventful. After the identification of granuloma, the patient was referred to a phthysiatric clinic for further diagnostics and treatment. The authors have deemed this case worthy of reporting primarily due to the exceptionally long period between the completion of BCG therapy and the onset of hepatic tumor.

Abstract
A granuloma is a compact organization of mature macrophages that forms because of persistent antigenic stimulation. At the microscopic level, granulomas can undergo various morphologic changes, ranging from necrosis to fibrosis, which along with other specialized immune cells define the appearance of the granulomatous process. Accordingly, the imaging features of granulomatous diseases vary and can overlap with those of other diseases, such as malignancy, and lead to surgical excisions and biopsy. However, given the heterogeneity of granulomas as a disease group, it is often hard to make a diagnosis on the basis of the histopathologic features of granulomatous diseases alone owing to overlapping microscopic features. Instead, a multidisciplinary approach is often helpful. Radiologists need to be familiar with the salient clinical manifestations and imaging findings of granulomatous diseases to generate an appropriate differential diagnosis. ©RSNA, 2021.

Abstract
Sarcoidosis is a multi-system disease of unknown etiology characterized by the formation of granulomas in various organs. It affects people of all ethnic backgrounds and occurs at any time of life but is more frequent in African Americans and Scandinavians and in adults between 30 and 50 years of age. Sarcoidosis can affect any organ with a frequency varying according to ethnicity, sex and age. Intrathoracic involvement occurs in 90% of patients with symmetrical bilateral hilar adenopathy and/or diffuse lung micronodules, mainly along the lymphatic structures which are the most affected system. Among extrapulmonary manifestations, skin lesions, uveitis, liver or splenic involvement, peripheral and abdominal lymphadenopathy and peripheral arthritis are the most frequent with a prevalence of 25-50%. Finally, cardiac and neurological manifestations which can be the initial manifestation of sarcoidosis, as can be bilateral parotitis, nasosinusal or laryngeal signs, hypercalcemia and renal dysfunction, affect less than 10% of patients. The diagnosis is not standardized but is based on three major criteria: a compatible clinical and/or radiological presentation, the histological evidence of non-necrotizing granulomatous inflammation in one or more tissues and the exclusion of alternative causes of granulomatous disease. Certain clinical features are considered to be highly specific of the disease (e.g., Löfgren's syndrome, lupus pernio, Heerfordt's syndrome) and do not require histological confirmation. New diagnostic guidelines were recently published. Specific clinical criteria have been developed for the diagnosis of cardiac, neurological and ocular sarcoidosis. This article focuses on the clinical presentation and the common differentials that need to be considered when appropriate.

Abstract
Infections caused by pathogens of the Mycobacterium tuberculosis complex, i. e., tuberculosis (TB), and the non-infectious, autoimmune disease sarcoidosis are among the most common granulomatous diseases worldwide. Typically, the lung is the primary site of infection and manifestation, respectively which makes the two diseases important differential diagnoses. Both diseases can affect virtually all organ systems, albeit with significantly lower incidence. CASE PRESENTATION: We report the case of a 50-year-old Indian man presenting with a tuberculous perihepatic abscess and a systemic inflammatory response after being diagnosed with neurosarcoidosis presenting as a single granuloma in the frontal lobe with lymphadenopathy in 2014. On day of admission the patient presented with right upper abdominal pain and fever for two weeks. With increased inflammatory parameters in serum and after finding of external CT images, a perihepatic abscess was suspected. This encapsulated cave was drained percutaneously under CT control. A high concentration of acid-fast rods was detected using ZN, PCR was positive for M. tuberculosis. Several samples of sputum and urine were microscopically negative but yielded growth of Mycobacteria after four weeks. DISCUSSION: This is a case presenting with two different granulomatous diseases, each of which manifested itself in an atypical form. The tuberculous liver abscess might either be explained as a flare-up of latent tuberculosis under azathioprine therapy or as a reinfection acquired during one of several visits in the high-prevalence country India. In addition, it must be discussed whether the cerebral granuloma in 2014 could have been an early stage of tuberculous granuloma. Sensitivity of ZN staining is significantly reduced in cerebral samples, and negative PCR-results might be due to low germ load or methodical issues, e. g., decreased sensitivity in formalin fixated samples.

Abstract
Granulomatous diseases may present with oral manifestations that are detectable by dental care providers. In certain cases, oral manifestations may precede systemic signs and symptoms. Dentists managing patients with these conditions may modify the dental treatment plan and possibly retain the support of other health professionals. This review gives an update on granulomatous diseases that can be faced by the dental practitioner.

Abstract
We examined a 22-year-old woman who was admitted to our hospital with abdominal distention. At 19 years of age, the patient presented with hepatosplenomegaly. She was examined several times in another hospital; however, the cause was unidentified. Our evaluation showed severe pancytopenia and a spleen 13×24 cm in size. The serum levels of angiotensin-converting enzyme and lysozyme were elevated. She was diagnosed with liver sarcoidosis based on non-caseating epithelioid granuloma in liver biopsy tissue. To improve the symptoms, splenectomy was performed, and her pancytopenia and symptoms improved. Sarcoidosis should be considered in cases of massive splenomegaly.

Abstract
For a few years, mineral oils and their potential adverse health effects have been a constant issue of concern in many regulatory areas such as food, cosmetics, other consumer products, and industrial chemicals. Analytically, two fractions can be distinguished: mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). This paper aims at assessing the bioaccumulative potential and associated histopathological effects of MOSH as well as the carcinogenic potential of MOAH for consumer-relevant mineral oils. It also covers the absorption, distribution, metabolism, and excretion of MOSH and MOAH upon oral and dermal exposures. The use and occurrence of consumer-relevant, highly refined mineral oils in food, cosmetics and medicinal products are summarized, and estimates for the exposure of consumers are provided. Also addressed are the challenges in characterizing the substance identity of mineral oil products under REACH. Evidence from more recent autopsy and biopsy studies, along with information on decreasing food contamination levels, indicates a low risk for adverse hepatic lesions that may arise from the retention of MOSH in the liver. With respect to MOAH, at present there is no indication of any carcinogenic effects in animals dermally or orally exposed to highly refined mineral oils and waxes. Such products are used not only in cosmetics but also in medicinal products and as additives in food contact materials. The safety of these mineral oil-containing products is thus indirectly documented by their prevalent and long-term use, with a simultaneous lack of clinical and epidemiological evidence for adverse health effects.

Abstract
Kalimeris indica (L.) Sch. Bip. is a traditional Chinese medicine (TCM) and a portion of food used for cooking in China. It has been demonstrated that an ethanol extract of K. indica has an anti-inflammatory effect by inhibition of nitric oxide (NO) production on murine macrophage RAW264.7 cells after lipopolysaccharide (LPS) induction. In this study, the hepatoprotective effects of the total phenolics of K. indica (TPK), the total triterpenes of K. indica (TTK), and the total flavones of K. indica (TFK) from ethanol extracts of K. indica were evaluated in Bacille Calmette-Guerin (BCG)/LPS-induced liver injury in vivo. The treatments of TPK, TTK, and TFK improved liver injury in mice. Additionally, all treatments significantly not only reduced the hepatic malondialdehyde (MDA) content and hepatic total nitric oxide synthase (tNOS) but also induced the hepatic superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity. The treatments of TPK and TTK significantly reduced the hepatic inducible nitric oxide synthase (iNOS). The treatments of TPK, TTK, and TFK reduced the serum total bilirubin (T-Bil), and only TFK treatment reduced the serum alanine aminotransferase (ALT). Our results suggest that TPK, TTK, and TFK from ethanol extracts of K. indica might play an essential protective role against BCG/LPS-induced liver injury in vivo.

Abstract
Amoxicillin-clavulanate (AC) is a common cause of drug-induced liver injury, either cholestatic or mixed with hepatitis pattern. Rarely, AC causes granulomatous hepatitis. We report a new case of AC-induced granulomatous hepatitis documented by liver biopsy, with complete resolution of any histological sequelae on a follow-up liver biopsy after AC was withdrawn.

Abstract
Hepatic granulomas caused by nontuberculous mycobacteria (NTM) are an uncommon, insidious, and indolent disease. Making an accurate diagnosis of a hepatic nontuberculous granuloma is challenging because of nonspecific clinical presentations and radiological appearances, especially in patients with a history of malignant tumors, as these lesions may mimic metastases and make a dilemma for decision-making in treatment. Herein, we report three cases of hepatic nontuberculous granulomas following operations for malignant tumors, including colon cancer, ovarian adenocarcinoma, and both rectal and renal carcinoma, respectively. Two patients presented with multiple hepatic lesions and the third had a solitary nodule in the liver. Computed tomography (CT) showed low attenuating nodules without early enhancement in the arterial phase but a slight peripheral enhancement in the portal venous phase after the intravenous administration of contrast agent. Magnetic resonance imaging (MRI) showed high signal intensity on T2-weighted image, rim enhancement in the venous phase and no contrast agent of Gd-EOB-DTPA uptake in the hepatobiliary phase. The biopsy was performed, and histopathological examinations revealed the chronic granulomas composed of epithelioid histiocytes, inflammatory cells, and Langhans giant cells. The results of nested polymerase chain reaction (PCR) were positive for NTM.

Almogairen SM. Abatacept induced granulomatous hepatitis with a sarcoidosis- like reaction: a blinded trial in mice. BMC Pharmacol Toxicol 2019; 20:26. [PMID: 31064410 PMCID: PMC6503540 DOI: 10.1186/s40360-019-0303-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2018] [Accepted: 04/22/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Abatacept is increasingly used for rheumatoid arthritis (RA) and juvenile idiophathic arthritis (JIA) treatment. However little is known about the risk of hepatotoxicity. The aim of this study was to determine whether the inhibition of the T cell CD28 receptor by abatacept results in acute hepatitis in BALB/c mice. METHODS Twenty BALB/c mice were studied. Ten mice received subcutaneous (SC) injection of abatacept (0.25mg per 25g body weight per 0.03 ml normal saline) at 0, 2, 4 and 8 weeks. For the control group, 10 mice received a SC injection of normal saline (NS) (0.03 ml). At the 10th week post injection, the mice were sacrificed, and histopathological studies were conducted. RESULTS Of the abatacept-treated group, 3/10 mice died. Liver histology for the abatacept-treated group showed that 6/7 displayed histopathological changes in the lobular cellular infiltrates of eosinophils, lymphocytes and histiocytes, in addition to granuloma formation. In contrast, only minimal inflammation was observed in 3/10 mice in the control group (p=0.036). CONCLUSION Abatacept may play a role in inducing granulomatous hepatitis with a sarcoidosis-like reaction. Additional data including transaminases, antinuclear antibodies (ANA), Antimitochondrial antibodies (AMA) and other auto antibodies should be tested.

Abstract
Abstract
Primary biliary cholangitis (PBC), an autoimmune liver disease occurring predominantly in women, is characterized by high titers of serum anti-mitochondrial antibodies (AMAs) and progressive intrahepatic cholestasis. The immune system plays a critical role in PBC pathogenesis and a variety of immune cell subsets have been shown to infiltrate the portal tract areas of patients with PBC. Amongst the participating immune cells, CD4 T cells are important cytokine-producing cells that foster an inflammatory microenvironment. Specifically, these cells orchestrate activation of other immune cells, including autoreactive effector CD8 T cells that cause biliary epithelial cell (BEC) injury and B cells that produce large quantities of AMAs. Meanwhile, other immune cells, including dendritic cells (DCs), natural killer (NK) cells, NKT cells, monocytes, and macrophages are also important in PBC pathogenesis. Activation of these cells initiates and perpetuates bile duct damage in PBC patients, leading to intrahepatic cholestasis, hepatic damage, liver fibrosis, and eventually cirrhosis or even liver failure. Taken together, the body of accumulated clinical and experimental evidence has enhanced our understanding of the immunopathogenesis of PBC and suggests that immunotherapy may be a promising treatment option. Herein, we summarize current knowledge regarding immunological abnormalities of PBC patients, with emphasis on underlying pathogenic mechanisms. The differential immune response which occurs over decades of disease activity suggests that different therapies may be needed at different stages of disease.

Abstract
INTRODUCTION Meningitis is the most severe manifestation of tuberculosis, resulting in death or disability in over 50% of those affected, with even higher morbidity and mortality among patients with HIV or drug resistance. Antimicrobial treatment of Tuberculous meningitis (TBM) is similar to treatment of pulmonary tuberculosis, although some drugs show poor central nervous system penetration. Therefore, intensification of antibiotic treatment may improve TBM treatment outcomes. Areas covered: In this review, we address three main areas: available data for old and new anti-tuberculous agents; intensified treatment in specific patient groups like HIV co-infection, drug-resistance, and children; and optimal research strategies. Expert commentary: There is good evidence from preclinical, clinical, and modeling studies to support the use of high-dose rifampicin in TBM, likely to be at least 30 mg/kg. Higher dose isoniazid could be beneficial, especially in rapid acetylators. The role of other first and second line drugs is unclear, but observational data suggest that linezolid, which has good brain penetration, may be beneficial. We advocate the use of molecular pharmacological approaches, physiologically based pharmacokinetic modeling and pharmacokinetic-pharmacodynamic studies to define optimal regimens to be tested in clinical trials. Exciting data from recent studies hold promise for improved regimens and better clinical outcomes in future.

Abstract
PURPOSE Drug-induced liver injuries (DILI) comprise a significant proportion of adverse drug reactions leading to hospitalizations and death. One frequent DILI is granulomatous inflammation from exposure to harmful metabolites that activate inflammatory pathways of immune cells of the liver, which may act as a barrier to isolate the irritating stimulus and limit tissue damage. METHODS Paralleling the accumulation of CFZ precipitates in the liver, granulomatous inflammation was studied to gain insight into its effect on liver structure and function. A structural analog that does not precipitate within macrophages was also studied using micro-analytical approaches. Depleting macrophages was used to inhibit granuloma formation and assess its effect on drug bioaccumulation and toxicity. RESULTS Granuloma-associated macrophages showed a distinct phenotype, differentiating them from non-granuloma macrophages. Granulomas were induced by insoluble CFZ cargo, but not by the more soluble analog, pointing to precipitation being a factor driving granulomatous inflammation. Granuloma-associated macrophages showed increased activation of lysosomal master-regulator transcription factor EB (TFEB). Inhibiting granuloma formation increased hepatic necrosis and systemic toxicity in CFZ-treated animals. CONCLUSIONS Granuloma-associated macrophages are a specialized cell population equipped to actively sequester and stabilize cytotoxic chemotherapeutic agents. Thus, drug-induced granulomas may function as drug sequestering "organoids" -an induced, specialized sub-compartment- to limit tissue damage.

Abstract
Abstract The six-banded armadillo (Euphractus sexcinctus) stands out among wild mammals due to the rare occurrence of spontaneous metabolic diseases. When altered, the liver, which is important in metabolism, may trigger a dysfunctional cascade, leading to hepatic steatosis. Here we describe a case of hepatic steatosis in a six-banded armadillo living in captivity. The female specimen was captured and donated to the Federal University of Piaui under SISBIO authorization nº53303. The animal was first referred for a veterinary clinical evaluation, and then euthanized following the ethical standards of the Federal Council of Veterinary Medicine. At the start of the dissection, the abdominal cavity was accessed and sections of all ex situ liver lobes, spleen and mandibular lymph node were subjected to routine histological processing; the results were photo documented. The anatomic and histopathological analysis confirmed the diagnosis of hepatic steatosis, which we propose is related to an infectious process as a result of the changes observed in the organs of the lymphoid system. This report of fatty liver disease in armadillo suggests an acute infectious process with lymphoid system involvement.

Abstract
Hepatitis C is a liver disease caused by infection of the Hepatitis C virus (HCV). Many individuals infected by the virus are unable to resolve the viral infection and develop chronic hepatitis, which can lead to formation of liver cirrhosis and cancer. To understand better how initial HCV infections progress to chronic liver diseases, we characterised the long term pathogenic effects of HCV infections with the use of a humanised mouse model (HIL mice) we have previously established. Although HCV RNA could be detected in infected mice up to 9 weeks post infection, HCV infected mice developed increased incidences of liver fibrosis, granulomatous inflammation and tumour formation in the form of hepatocellular adenomas or hepatocellular carcinomas by 28 weeks post infection compared to uninfected mice. We also demonstrated that chronic liver inflammation in HCV infected mice was mediated by the human immune system, particularly by monocytes/macrophages and T cells which exhibited exhaustion phenotypes. In conclusion, HIL mice can recapitulate some of the clinical symptoms such as chronic inflammation, immune cell exhaustion and tumorigenesis seen in HCV patients. Our findings also suggest that persistence of HCV-associated liver disease appear to require initial infections of HCV and immune responses but not long term HCV viraemia.

Abstract
We describe a case of a 23-year-old woman with a history of Crohn's disease (CD), who initially presented with sepsis-like symptoms, subsequently developed severe cholestasis and following extensive inpatient workup was found to have non-caseating granulomas on her liver biopsy. Infectious aetiologies were excluded and the patient was treated with oral corticosteroids, which ameliorated but did not completely reverse the cholestasis. We review the differential diagnosis of hepatic granulomas and discuss the potential difficulties in establishing their exact aetiology in patients with CD.

Abstract
A shortage of donor organs is a major limitation to liver transplantation. Expansion of donor pool criteria to include patients with schistosomiasis diagnosed on liver biopsy might allow the allocation of more transplant livers. Schistosomiasis is a chronic parasitic disease affecting millions in endemic areas including sub-Sahara Africa that might lead to the development of granulomas as a response to the parasite’s ova and might cause chronic liver disease and portal hypertension. Due to increased mobility globally, schistosomiasis may be encountered in non-endemic areas. Currently, the usage of donor livers with known Schistosomiasis is not universally defined.

Abstract
BACKGROUND Although Mycobacterium tuberculosis (TB) infection may cause extrapulmonary disease in HIV-infected adults, HIV-associated hepatic TB has been poorly characterized. Our objective was to describe hepatic TB in HIV-infected adults. METHODS Retrospective study of patients diagnosed with hepatic TB from 2005-2012 at Infectious Diseases Clinic, King Edward VIII Hospital, Durban, South Africa. RESULTS Among twenty cases of histology-confirmed HIV-associated hepatic TB, median CD4 count was 47 cells/μl (inter-quartile range 27-107 cells/μl) and 75% (15/20) of patients had pre-existing pulmonary TB. The most frequent clinical finding was hepatomegaly (85%). Liver enzyme abnormalities included elevated alkaline phosphatase (median 456 u/L, inter-quartile range 322-1,043 u/L) and gamma-glutamyltransferase (median 422 u/L, inter-quartile range 235-736 u/L). Acid-fast bacilli were cultured from liver tissue in 30% (6/20) of patients; 25% (5/20) identified as TB. With standard anti-TB therapy, liver enzymes improved within six months in 92% (11/12) of patients. One year after diagnosis, twelve patients resolved clinically, two patients developed drug-resistant TB and six patients died. CONCLUSION In our case series of HIV-infected patients, hepatic TB occurred in patients with severe immunosuppression, who presented with hepatomegaly and abnormal liver enzymes. More than half of patients had resolution of liver function by six months however the 12-month mortality remained high.

Abstract
Background Mycobacterium tuberculosis (TB) infection of the liver, known as hepatic TB, is an extrapulmonary manifestation of TB. Hepatic TB has become more prevalent, likely as a result of the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic. We sought to review case series to characterize the epidemiology, pathophysiology, clinical features, diagnosis, and treatment of hepatic TB and to comment on the impact of HIV co-infection on these characteristics. Methods We conducted a systematic literature search in PubMed and ScienceDirect for articles pertaining to hepatic TB with human subjects from 1960 to July 2013. Results We obtained data on 618 hepatic TB patients from 14 case series. The most common reported signs and symptoms were hepatomegaly (median: 80%, range: 10-100%), fever (median: 67%, range: 30–100), respiratory symptoms (median: 66%, range: 32-78%), abdominal pain (median: 59.5%, range: 40-83%), and weight loss (median: 57.5%, range: 20-100%). Common laboratory abnormalities were elevated alkaline phosphatase and gamma-glutamyl transferase. Ultrasound and computerized tomography (CT) were sensitive but non-specific. On liver biopsy, smear microscopy for acid-fast bacilli had a median sensitivity of 25% (range: 0-59%), histology of caseating granulomas had a median sensitivity of 68% (range: 14-100%), and polymerase chain reaction for TB had a median sensitivity of 86% (range: 30-100%). Standard anti-tuberculous chemotherapy for 6 to 12 months achieved positive outcomes for nearly all patients with drug-susceptible TB. Conclusions Clinicians in TB-endemic regions should maintain a high index of suspicion for hepatic TB in patients presenting with hepatomegaly, fever, respiratory symptoms, and elevated liver enzymes. The most sensitive imaging modality is a CT scan, while the most specific diagnostic modality is a liver biopsy with nucleic acid testing of liver tissue samples. Upon diagnosis, 4-drug anti-TB therapy should promptly be initiated. HIV co-infected patients may have more complex cases and should be closely monitored for complications.

Abstract
The liver is one of the most commonly involved extrapulmonary sites in sarcoidosis. Hepatic sarcoidosis has a broad range of presentations from scattered, asymptomatic noncaseating granulomas with normal liver enzymes, which are very common in patients with known pulmonary sarcoidosis, to portal hypertension and cirrhosis, which are relatively uncommon. Diagnosis is based on a combination of clinical, laboratory and histological manifestations. The authors' protocol for management of patients with suspected sarcoidosis of the liver without focal lesions includes a transjugular liver biopsy with portal pressure measurements to confirm the diagnosis, rule out coexisting liver diseases and to identify select patients with fibrosis or portal hypertension for consideration of immunosuppression. Steroids and azathioprine are the preferred agents and methotrexate is not recommended.

Abstract
Hepatic tuberculosis (HTB) is commonly encountered in patients with widespread miliary disease. Isolated affection of the liver is extremely rare. We present a case of a young woman who presented with a subacute afebrile hepatic failure. Investigations including a liver biopsy proved that the presentation was due to granulomatous hepatitis secondary to mycobacterial infection of the liver. It is important that tuberculosis (TB) be kept in mind especially in endemic areas even in atypical clinical scenarios by clinicians, radiologists, and pathologists. Use of anti-tuberculous drugs in such cases is usually successful and must be instituted early.

Abstract
BACKGROUND Toxoplasmosis is becoming a global health hazard as it infects 30-50% of the world human population. Clinically, the life-long presence of the parasite in tissues of a majority of infected individuals is usually considered asymptomatic. However, a number of studies show that this 'asymptomatic infection' may also lead to development of other human pathologies. AIMS OF THE STUDY The purpose of the study was to collect available geoepidemiological data on seroprevalence of toxoplasmosis and search for its relationship with mortality and disability rates in different countries. METHODS AND FINDINGS Prevalence data published between 1995-2008 for women in child-bearing age were collected for 88 countries (29 European). The association between prevalence of toxoplasmosis and specific disease burden estimated with age-standardized Disability Adjusted Life Year (DALY) or with mortality, was calculated using General Linear Method with Gross Domestic Product per capita (GDP), geolatitude and humidity as covariates, and also using nonparametric partial Kendall correlation test with GDP as a covariate. The prevalence of toxoplasmosis correlated with specific disease burden in particular countries explaining 23% of variability in disease burden in Europe. The analyses revealed that for example, DALY of 23 of 128 analyzed diseases and disease categories on the WHO list showed correlations (18 positive, 5 negative) with prevalence of toxoplasmosis and another 12 diseases showed positive trends (p<0.1). For several obtained significant correlations between the seroprevalence of toxoplasmosis and specific diseases/clinical entities, possible pathophysiological, biochemical and molecular explanations are presented. CONCLUSIONS The seroprevalence of toxoplasmosis correlated with various disease burden. Statistical associations does not necessarily mean causality. The precautionary principle suggests however that possible role of toxoplasmosis as a triggering factor responsible for development of several clinical entities deserves much more attention and financial support both in everyday medical practice and future clinical research.

Abstract
Hepatic tuberculosis as a part of disseminated tuberculosis is seen in 50-80% of cases. Isolated hepatic tuberculosis is very uncommon even in countries with high prevalence of tuberculosis. It can occur as a primary case or due to reactivation of an old tubercular focus. We report a case of a 59-year-old Caucasian woman who presented with persistent right upper quadrant pain and a hepatic lesion on an abdominal CT. She had a history of pulmonary tuberculosis 15 years ago with localised lung tuberculosis treated with lobectomy and antituberculous drugs.

Abstract
Sarcoidosis is a multisystem disease characterized by the presence of non-caseating granulomas in affected organs. Pulmonary involvement is the most common site of disease activity. However, hepatic involvement is also common in sarcoidosis, occurring in up to 70% of patients. Most patients with liver involvement are asymptomatic. Therefore, the majority of cases are discovered incidentally, frequently by the finding of elevated liver enzymes. Pain in the right upper quadrant of the abdomen, fatigue, pruritus, and jaundice may be associated with liver involvement. Portal hypertension and cirrhosis are complications linked to long-standing hepatic sarcoidosis. Liver biopsy is usually required to confirm the diagnosis. It is important to differentiate hepatic sarcoidosis from other autoimmune and granulomatous liver diseases. Not all cases of hepatic sarcoidosis require treatment. For symptomatic patients, the first line treatment includes corticosteroids or ursodeoxycholic acid. Various immunosuppressant agents can be used as second line agents. Rarely, severe cases require liver transplantation.

Abstract
Drug-induced hepatotoxicity is underrecognized but increasingly identified as causing acute and chronic liver disease. Several prescription drugs, over-the-counter medications, dietary and/or supplementary agents, and herbal products are hepatotoxic. Drug-induced liver injury mimics other primary acute and chronic liver diseases and it should be considered in patients with hepatobiliary disease. Certain drugs result in specific histopathologic patterns of liver injury, which may help in sorting out the responsible drug. The diagnosis of drug-induced hepatotoxicity is challenging. It involves excluding other possible causes, careful medication history, the latent period between drug exposure and symptom onset and/or abnormal liver tests, and histopathologic findings.

Abstract
Liver abnormalities are often seen in bowel diseases. Whether these represent aspects of two separate diseases, or if one is causing the other, is not always easy to decide. Extraintestinal manifestations of inflammatory bowel disease (IBD) or coeliac disease are frequently observed. Of these extraintestinal manifestations, hepatic disorders are among the most common. Primary sclerosing cholangitis (PSC) and primary biliary cirrhosis are the most frequent hepatic disorders in IBD and coeliac disease, respectively. Genetic studies have lately elucidated the associations between IBD and PSC, but there is still a long way until we have complete understanding of the molecular aetiology and pathophysiology of these conditions. There is no curative treatment available for PSC, besides liver transplantation. Steatosis and cholelithiasis are also common in IBD, as are signs of hepatic injury due to IBD treatment. Less common liver abnormalities include liver abscesses, hepatic thromboembolic events, granulomatous liver disease and hepatic amyloidosis.

Selenium and selenoprotein deficiencies induce widespread pyogranuloma formation in mice, while high levels of dietary selenium decrease liver tumor size driven by TGFα. PLoS One 2013; 8:e57389.

Abstract
Changes in dietary selenium and selenoprotein status may influence both anti- and pro-cancer pathways, making the outcome of interventions different from one study to another. To characterize such outcomes in a defined setting, we undertook a controlled hepatocarcinogenesis study involving varying levels of dietary selenium and altered selenoprotein status using mice carrying a mutant (A37G) selenocysteine tRNA transgene (Trsp(tG37) ) and/or a cancer driver TGFα transgene. The use of Trsp(tG37) altered selenoprotein expression in a selenoprotein and tissue specific manner and, at sufficient dietary selenium levels, separate the effect of diet and selenoprotein status. Mice were maintained on diets deficient in selenium (0.02 ppm selenium) or supplemented with 0.1, 0.4 or 2.25 ppm selenium or 30 ppm triphenylselenonium chloride (TPSC), a non-metabolized selenium compound. Trsp(tG37) transgenic and TGFα/Trsp(tG37) bi-transgenic mice subjected to selenium-deficient or TPSC diets developed a neurological phenotype associated with early morbidity and mortality prior to hepatocarcinoma development. Pathology analyses revealed widespread disseminated pyogranulomatous inflammation. Pyogranulomas occurred in liver, lungs, heart, spleen, small and large intestine, and mesenteric lymph nodes in these transgenic and bi-transgenic mice. The incidence of liver tumors was significantly increased in mice carrying the TGFα transgene, while dietary selenium and selenoprotein status did not affect tumor number and multiplicity. However, adenoma and carcinoma size and area were smaller in TGFα transgenic mice that were fed 0.4 and 2.25 versus 0.1 ppm of selenium. Thus, selenium and selenoprotein deficiencies led to widespread pyogranuloma formation, while high selenium levels inhibited the size of TGFα-induced liver tumors.
