Assessment of Liver Involvement in Patients With Type 2 Diabetes Mellitus in Basrah City, Iraq, Using FibroScan and Correlation With Risk Factors

The non-invasive evaluation of liver involvement in patients with cystic fibrosis: A prospective study.

Porto-sinusoidal vascular disease (PSVD) has been described as the prominent pathology in liver explants of patients with cystic fibrosis (CF), but data outside the transplant setting are lacking. We aimed to investigate the prevalence of portal hypertension (PH) in CF-associated liver disease (CFLD) and develop an algorithm to classify liver involvement in CF patients. This is a cross-sectional study of consecutive paediatric and adult patients in a tertiary centre between 2018 and 2019, who underwent ultrasound, liver (LSM) and spleen stiffness (SSM) measurement. CFLD was defined according to physical examination, liver tests and ultrasound findings. PSVD was likely if there were PH signs in the absence of advanced chronic liver disease (CF-ACLD, LSM <10 kPa). A historical cohort was used to validate the prognostic significance of the new definitions. Fifty (27.5%) patients met CFLD criteria. At least one sign of PH was found in 47 (26%) patients, but most (81%) had LSM <10 kPa and were likely to have PSVD; only 9 (5%) had CF-ACLD. PSVD and CFLD (LSM <10 kPa) co-existed in most (23/36) cases. In the historical cohort (n = 599 patients), likely PSVD and CFLD+PH were independently associated with a 2-fold and 3.5-fold increase in mortality compared to patients without PH, respectively. In 34 patients with SSM, values <21 and >50 kPa accurately diagnosed specific signs of PH. PSVD is the prevailing cause of PH in CF patients. We developed a new diagnostic algorithm based on clinical and elastosonography criteria to classify liver involvement in patients with CF.

Hepatic Involvement across the Metabolic Syndrome Spectrum: Non-Invasive Assessment and Risk Prediction Using Machine Learning.

Metabolic-dysfunction-associated steatotic liver disease (MASLD) and metabolic syndrome (MetS) are inextricably linked conditions, both of which are experiencing an upward trend in prevalence, thereby exerting a substantial clinical and economic burden. The presence of MetS should prompt the search for metabolic-associated liver disease. Liver fibrosis is the main predictor of liver-related morbidity and mortality. Non-invasive tests (NIT) such as the Fibrosis-4 index (FIB4), aspartate aminotransferase-to-platelet ratio index (APRI), aspartate aminotransferase-to-alanine aminotransferase ratio (AAR), hepatic steatosis index (HIS), transient elastography (TE), and combined scores (AGILE3+, AGILE4) facilitate the detection of liver fibrosis or steatosis. Our study enrolled 217 patients with suspected MASLD, 109 of whom were diagnosed with MetS. We implemented clinical and biological evaluations complemented by transient elastography (TE) to discern the most robust predictors for liver disease manifestation patterns. Patients with MetS had significantly higher values of FIB4, APRI, HSI, liver stiffness, and steatosis parameters measured by TE, as well as AGILE3+ and AGILE4 scores. Machine-learning algorithms enhanced our evaluation. A two-step cluster algorithm yielded three clusters with reliable model quality. Cluster 1 contained patients without significant fibrosis or steatosis, while clusters 2 and 3 showed a higher prevalence of significant liver fibrosis or at least moderate steatosis as measured by TE. A decision tree algorithm identified age, BMI, liver enzyme levels, and metabolic syndrome characteristics as significant factors in predicting cluster membership with an overall accuracy of 89.4%. Combining NITs improves the accuracy of detecting patterns of liver involvement in patients with suspected MASLD.

Liver Involvement in Patients with Systemic Sclerosis: Role of Transient Elastography in the Assessment of Hepatic Fibrosis and Steatosis.

Background Systemic sclerosis (SSc) is a rare, multisystemic disorder of connective tissue characterized by widespread inflammation, vascular abnormalities, and both skin and visceral organ fibrosis. Tissue fibrosis is the final phase of a complex biological process of immune activation and vascular damage. Objectives The aim of the study was to assess hepatic fibrosis and steatosis in SSc patients by transient elastography (TE). Methods Fifty-nine SSc patients fulfilling the 2013 ACR/EULAR classification criteria were recruited. Clinical and laboratory findings, modified Rodnan skin score (mRSS), activity index, videocapillaroscopy, echocardiography, and lung function data were analyzed. Liver stiffness (LS) was measured by transient elastography (TE), with 7 kPa used as the cut-off value for significant liver fibrosis. In addition, hepatic steatosis was evaluated by means of controlled attenuation parameter (CAP) findings. Specifically, CAP values ≥ 238 ≤ 259 dB/m were considered consistent with mild steatosis (S1), values ≥ 260 ≤ 290 dB/m were compatible with moderate steatosis (S2), and values ≥ 291 dB/m were indicative of severe steatosis (S3). Results The median age of patients was 51 years, with a median disease duration of 6 years. The median LS was 4.5 (2.9-8.3) kPa; 69.5% of patients had no evidence of fibrosis (F0); 27.1% displayed LS values between 5.2 and 7 kPa; and only 3.4% of patients had LS values > 7 kPa (F3). The median CAP value for liver steatosis was 223 dB/m (IQR: 164-343). Overall, 66.1% of patients did not show evidence of steatosis (CAP values < 238 dB/m); 15.2% showed values consistent with mild (S1) steatosis (CAP value ≥ 238 ≤ 259 dB/m); 13.5% had moderate (S2) steatosis (CAP value ≥ 260 ≤ 290 dB/m); and 5.1% were deemed to have severe steatosis (S3) due to CAP values ≥ 291 dB/m. Conclusions Although systemic sclerosis is associated with fibrosis of the skin and several organs, only 3.4% of our patient population showed evidence of marked liver fibrosis, which is the same prevalence as that expected in the general population. Therefore, fibrosis of the liver did not appear to be a significant concern in SSc patients, albeit moderate fibrosis could still be detected in a significant proportion of subjects. A prolonged follow-up may clarify whether liver fibrosis in SSc patients may still progress. Likewise, the prevalence of significant steatosis was low (5.1%) and depended on the same variables associated with fatty liver disease in the general population. TE was shown to be an easy and valuable method for detection and screening of hepatic fibrosis in SSc patients with no additional risk factors for liver disease and may be useful to assess the potential progression of liver fibrosis over time.

Liver involvement in patients with COVID-19 infection: A comprehensive overview of diagnostic imaging features

During the first wave of the pandemic, coronavirus disease 2019 (COVID-19) infection has been considered mainly as a pulmonary infection. However, different clinical and radiological manifestations were observed over time, including involvement of abdominal organs. Nowadays, the liver is considered one of the main affected abdominal organs. Hepatic involvement may be caused by either a direct damage by the virus or an indirect damage related to COVID-19 induced thrombosis or to the use of different drugs. After clinical assessment, radiology plays a key role in the evaluation of liver involvement. Ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI) may be used to evaluate liver involvement. US is widely available and it is considered the first-line technique to assess liver involvement in COVID-19 infection, in particular liver steatosis and portal-vein thrombosis. CT and MRI are used as second- and third-line techniques, respectively, considering their higher sensitivity and specificity compared to US for assessment of both parenchyma and vascularization. This review aims to the spectrum of COVID-19 liver involvement and the most common imaging features of COVID-19 liver damage.

Guía de Práctica Clínica para el diagnóstico de compromiso orgánico en amiloidosis: Parte 3/3 Año 2020

Method: Use the PICO format to generate a series of questions, focusing on the specificity and sensitivity of the amyloidosis diagnostic test. PubMed searches were conducted in English and Spanish from July to August 2019. The level of evidence and recommendation are based on the GRADE system (http://www.gradeworkinggroup.org/index.htm). The recommendations are graded according to their direction (for or against) and strength (strong and weak). Finally, it is recommended to use GLIA tools to evaluate the obstacles and facilitators in implementation. Suggested explanation A strong suggestion indicates a high degree of trust in support or opposition to the intervention. When defining a strong recommendation, this guide uses the "recommended" language. The weaker recommendations indicate that the outcome of the intervention (favorable or unfavorable) is doubtful. In this case, if a weak recommendation is defined, the "recommendation" language is used. How to use these guidelines: Recommendations must be explained within the scope of special care in validated diagnostic studies conducted by specially trained doctors. It is not assumed to change the coexistence conditions of the disease process. Presumably, the attending physician has a high degree of suspicion of amyloidosis. It assumes that diagnostic research is conducted by well-trained doctors using a validated standardized method. This guide is intended for health care professionals and those involved in health care policies to help ensure that the necessary agreements have been reached to provide appropriate care. Summary of recommendations For patients with suspected amyloidosis, it is recommended: Measured value of creatinine be used as a preliminary assessment for the diagnosis of renal involvement in patients with suspected renal amyloidosis. 24-hour proteinuria be measured and characterized to diagnose renal involvement in patients with suspected renal amyloidosis. Immunohistochemical staining of skin biopsy for patients genetically diagnosed with ATTR, for early diagnosis of neuropathy. The signs or symptoms of these patients suggest the presence of fine fiber neuropathy. Skin biopsy and immunohistochemical staining for early diagnosis of neuropathy. These patients show signs or symptoms suggesting fine fiber neuropathy. Conduct nerve conduction studies on motor and sensory fibers to diagnose total fiber neuropathy in patients who are diagnosed or suspected of having amyloidosis. Test (Sudoscan) is recommended for the early diagnosis of peripheral autonomic neuropathy (even in asymptomatic patients) in patients with suspected autonomic neuropathy due to amyloidosis. Ewing's standard to measure heart rate variability to diagnose autonomic hypofunction in patients with autonomic neuropathy suspected of having amyloidosis. Measure orthostatic hypotension to diagnose early autonomic hypotension for patients with amyloidosis or systemic amyloidosis suspected of autonomic neuropathy. It is suggested: QST test to diagnose neuropathy early for patients genetically diagnosed with ATTR, if they show signs or symptoms suggesting fine fiber neuropathy Measure alkaline phosphatase to initially assess liver involvement in patients with amyloidosis.

Hepatic manifestations of coronavirus disease 2019 infection: Clinical and laboratory perspective.

The novel coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2, has become a global challenge of unprecedented nature since December 2019. Although most patients with COVID-19 exhibit mild clinical manifestations and upper respiratory tract involvement, in approximately 5%-10% of patients, the disease is severe and involves multiple organs, leading to multi-organ dysfunction and failure. The liver and gastrointestinal tract are also frequently involved in COVID-19. In the context of liver involvement in patients with COVID-19, many key aspects need to be addressed in both native and transplanted organs. This review focuses on the clinical presentations and laboratory abnormalities of liver function tests in patients with COVID-19 with no prior liver disease, patients with pre-existing liver diseases and liver transplant recipients. A brief overview of the history of COVID-19 and etiopathogenesis of the liver injury will also be described as a prelude to better understanding the above aspects.

Chronic liver disease and hepatic calcium-oxalate deposition in patients with primary hyperoxaluria type I

Patients with primary hyperoxaluria type I (PH I) are prone to develop early kidney failure. Systemic deposition of calcium-oxalate (CaOx) crystals starts, when renal function declines and plasma oxalate increases. All tissue, but especially bone, heart and eyes are affected. However, liver involvement, as CaOx deposition or chronic hepatitis/fibrosis has never been reported. We examined liver specimen from 19 PH I patients (aged 1.5 to 52 years at sample collection), obtained by diagnostic biopsy (1), at autopsy (1), or transplantation (17). With polarization microscopy, birefringent CaOx crystals located in small arteries, but not within hepatocytes were found in 3/19 patients. Cirrhosis was seen in one, fibrosis in 10/19 patients, with porto-portal and nodular fibrosis (n = 1), with limitation to the portal field in 8 and/or to central areas in 5 patients. Unspecific hepatitis features were observed in 7 patients. Fiber proliferations were detectable in 10 cases and in one sample transformed Ito-cells (myofibroblasts) were found. Iron deposition, but also megakaryocytes as sign of extramedullary erythropoiesis were found in 9, or 3 patients, respectively. Overall, liver involvement in patients with PH I was more pronounced, as previously described. However, CaOx deposition was negligible in liver, although the oxalate concentration there must be highest.

Nutritional Interventions for Patients with Mitochondrial POLG-Related Diseases: A Systematic Review on Efficacy and Safety.

Ketogenic diet is recommended as a treatment to reduce seizure frequency in patients with intractable epilepsy. The evidence and safety results are sparse for diet interventions in patients with pathogenic polymerase gamma (POLG) variants and intractable epilepsy. The aim of this systematic review is to summarize the efficacy of diet treatment on seizure frequency, clinical symptoms, and potential deleterious effect of liver involvement in patients with mitochondrial diseases caused by pathogenic POLG variants. Literature was searched in PubMed, Embase; and Cochrane in April 2022; no filter restrictions were imposed. The reference lists of retrieved studies were checked for additional literature. Eligibility criteria included verified pathogenic POLG variant and diet treatment. Overall, 880 studies were identified, providing eight case-reports representing nine patients eligible for inclusion. In eight of nine cases, clinical symptoms were improved; six out of nine cases reported improvements in seizure frequency. However, increasing levels of liver enzymes after initiating ketogenic diet were found in four of the nine cases, with one case revealing decreased levels of liver enzymes after initiating long-chain triglyceride restriction. Viewed together, the studies imply that ketogenic diet can have a positive impact on seizure frequency, but may induce progression of liver impairment in patients with pathogenic POLG variants.

MO096: Chronic Liver Disease and Hepatic Calcium-Oxalate Deposition in Patients with Primary Hyperoxaluria Type I

Abstract BACKGROUND AND AIMS Patients with primary hyperoxaluria type I (PH I) are prone to develop early end-stage kidney failure (ESKF). Systemic deposition of calcium-oxalate (CaOx) crystals starts when renal function declines and plasma oxalate (Pox) increases &amp;gt;30 µmol/L. It is anticipated that all parenchymal organs, but also bone (marrow), retina and the central nervous system can be involved. However, liver involvement, either as CaOx deposition or as chronic hepatitis/fibrosis, was never reported. METHOD We now examined liver involvement in 19 patients with PH I aged 1.5–52 years. Liver specimen was obtained by biopsy for diagnostic purposes (1), at autopsy (1) or at the time of combined or sequential liver kidney transplantation (17). RESULTS With polarization microscopy, crystals with the typical star-like appearance of CaOx were found in 3/19 patients. The crystals were located in small arteries but not within hepatocytes. Cirrhosis was seen in one patient. Fibrosis was seen in 10/19 patients, with porto-portal and nodular fibrosis (n = 1), and a limitation of fibrosis to the portal field in eight and/or to central areas in five patients. Unspecific hepatitis features were observed in seven patients. Fiber proliferations were detectable in 10 cases, and in one sample, transformed Ito-cells (myofibroblasts) were found. Iron deposition but also megakaryocytes as a sign of extramedullary erythropoiesis were found in nine and three patients, respectively. CONCLUSION Overall, liver involvement in patients with PH I was more pronounced, as previously described. However, compared with CaOx deposition in other organs/tissue, such crystal accumulations were only minimal in the liver, although the oxalate concentration must be the highest.

Liver involvement in patients with erythropoietic protoporphyria.

In erythropoietic protoporphyria (EPP), which presents with severe painful phototoxicity, progressive deposition of protoporphyrins in hepatocytes and bile canaliculi may result in liver disease. Clinically EPP related liver disease ranges from mildly elevated liver enzymes to cirrhosis and acute cholestatic hepatic failure. The prevalence of liver disease in EPP, and factors predicting the risk of developing liver disease, have not been defined in a large series of unselected EPP patients. To determine the prevalence of liver disease in EPP-patients. A single-center prospective unselected cohort study of 114 adult EPP patients, who underwent routine laboratory testing, abdominal ultrasonography and transient elastography to assess the presence of steatosis (controlled attenuation parameter,dB/m) and liver stiffness (kPa). 114 adult EPP patients were included. Elevated liver enzymes were found in 6.2% of the patients. Liver steatosis was detected in 29.0%, and significant fibrosis as assessed with liver stiffness measurements was present in 9.6% of patients. BMI positively predicted CAP-values (p=0.026); and protoporphyrin IX levels (p=0.043) positively predicted liver stiffness. This study demonstrates a prevalence of hepatic steatosis and fibrosis in adult EPP-patients comparable to that found in the general population. Protoporphyrin IX levels correlate with increased liver stiffness in EPP.

Liver involvement in patients with erythropoietic protoporphyria: retrospective analysis of clinicopathological features of 5 cases

Erythropoietic protoporphyria (EPP) is a rare inherited disease whose morbidity is about 1:75,000 to 1:200,000. It is caused by the deficiency of porphyrin ferrochelatase (FECH). Liver involvement in EPP is even rarer. The diagnosis of EPP with liver involvement mainly relies on clinical manifestations, laboratory examinations, histopathological examinations and genetic testing, which is still a huge challenge for both clinicians and pathologists. Here, 5 cases of EPP with liver injury were collected, and the clinicopathological features of these patients were analyzed. The clinical manifestations and laboratory examinations varied from person to person, whereas the liver biopsies showed that there were dark brown deposits within the hepatocytes, Kupffer cells, bile canaliculi and the lumen of bile ducts, which was a constant finding by histopathological examination. Gene tests were conducted in two of the five cases, and the results confirmed the diagnosis. Fully understanding of the diseases can help us reduce the rate of missed diagnosis and provide proper treatment as early as possible.

Identification and validation of circulating miRNAs as potential new biomarkers for severe liver disease in patients with leptospirosis.

BackgroundLeptospirosis, a global zoonotic infectious disease, has various clinical manifestations ranging from mild self-limiting illness to life-threatening with multi-organ damage, including liver involvement. This study was aimed at identifying circulating microRNAs (miRNAs) as novel biomarkers for predicting severe liver involvement in patients with leptospirosis.MethodsIn a discovery set, 12 serum samples of patients with anicteric and icteric leptospirosis at initial clinical presentation were used for miRNA profiling by a NanoString nCounter miRNA assay. In a validated cohort, top candidate miRNAs were selected and further tested by qRT-PCR in serum samples of 81 and 16 individuals with anicteric and icteric leptospirosis, respectively.ResultsThe discovery set identified 38 significantly differential expression miRNAs between the two groups. Among these, miR-601 and miR-630 were selected as the top two candidates significantly up-regulated expressed in the icteric group. The enriched KEGG pathway showed that these miRNAs were mainly involved in immune responses and inflammation. In the validated cohort, miR-601 and miR-630 levels were significantly higher in the icteric group compared with the anicteric group. Additionally, these two miRNAs displayed good predictors of subsequent acute liver failure with a high sensitivity of 100%. On regression analysis, elevated miR-601 and miR-630 expression were also predictive of multi-organ failures and poor overall survival.ConclusionOur data indicated that miRNA expression profiles were significantly differentiated between the icteric and anicteric groups. Serum miR-601 and miR-630 at presentation could potentially serve as promising biomarkers for predicting subsequent acute liver failure and overall survival in patients with leptospirosis.

Pattern and Prevalence of Liver Involvement in Pediatric Acute Lymphoblastic and Myeloid Leukemia at Diagnosis.

The prevalence and significance of liver involvement at diagnosis was studied in pediatric acute lymphoblastic (ALL) and myeloid leukemia (AML). A population based cohort of 122 pre B-ALL, 22 T-ALL and 45 AML patients was formed from the Nordic Society of Pediatric Hematology and Oncology leukemia registries (years 2005-2017). Hepatomegaly, elevated alanine aminotransferase, high INR, hypoalbuminemia and conjugated hyperbilirubinemia at diagnosis were used as markers for liver involvement. Minimal residual disease (MRD), time to relapse and overall survival (OS) were correlated with liver involvements. The pattern of liver involvement was significantly different between leukemia subtypes (P = 0.025). The proportion of patients without liver abnormalities was 50.0% in AML and 44.8% in pre B-ALL and 23.5% in T-ALL patients. Hepatomegaly characterized lymphatic leukemia being present in 41.8% and 58.8% of pre B- and T-ALL patients. Liver dysfunction was most common in AML (29.5%) and least frequent in pre B-ALL (7.4%,) (P = 0.001). Conjugated hyperbilirubinemia was present in less than 5% of patients. Hepatomegaly correlated positively with age in pre B-ALL (P = 0.036) and white blood cell count (WBC) in AML (P = 0.010). Hepatic dysfunction was related with high WBC in pre B-ALL (P = 0.037) and AML (P = 0.001). Liver involvement in patients with ALL was not associated with toxicity or outcome. Patients with AML without liver involvement demonstrated superior OS. Liver involvement is frequent at diagnosis in pediatric leukemia and its prevalence is related with leukemia subtype, age and WBC. In AML, but not in ALL, it associates with suboptimal prognosis.

Liver involvement in patients with systemic lupus erythematosus

Liver involvement in systemic lupus erythematosus is common and in most cases clinical course is asymptomatic, that makes diagnosis difficult. Determination of the cause of the liver involvement is important to select treatment and to evaluate the prognosis of the disease.The aim of the research was to characterize the clinical features of liver involvement in patients with systemic lupus erythematosus and identify the most significant clinical and laboratory parameters for the differential diagnosis of lupus hepatitis.Materials and methods. The study included 313 patients with systemic lupus erythematosus observed in the E.M. Tareev Clinic of Rheumatology, Internal Medicine and Occupational Diseases of I.M. Sechenov First Moscow State Medical University (Sechenov University) in the period from 2001 to 2019. The verification of diagnosis of systemic lupus erythematosus was based on the criteria of the American College of Rheumatology (1997). Patients examination included complete blood count, biochemical and immunological blood tests and an abdominal ultrasonography. In 13 cases hepatic autoantibodies (ASMA, anti-LKM-1, LC-1, SLA-LP, AMA-M2) were analyzed, in 4 – magnetic resonance cholangiopancreatography and in 6 – liver biopsy were made.Results. Liver involvement were represented by an increase of liver enzymes in 58 (18.5%) cases. Chronic viral hepatitis C was diagnosed in 4 (1.3%) patients. Drug-induced hepatitis was found in 17 (5.4%) patients. Autoimmune liver diseases occured in 2 (0.6%) patients. In 2 (0.6%) patients, liver damage was associated with thrombotic microangiopathy (atypical hemolytic uremic syndrome, hereditary thrombophilia). In 15 (4.8%) cases, the most likely diagnosis was NAFLD. Lupus hepatitis was the most likely cause in 18 (5.7%) patients. Differential diagnosis in cases of liver involvement in patients with systemic lupus erythematosus requires assessment of risk factors for various liver diseases, age of the patients, level of liver enzymes, lupus activity, ultrasound signs of liver steatosis and secondary antiphospholipid syndrome.Determining the cause of the liver involvement for the patients with the systemic lupus erythematosus allows establishing better treatment tactic and improvement of the prognosis.

A Cohort Study of Liver Involvement in Patients With Adult-Onset Still's Disease: Prevalence, Characteristics and Impact on Prognosis.

Objective: Adult-onset Still's disease (AOSD) is a systemic disorder commonly accompanied by liver involvement. This study aims to illustrate the detailed information of liver abnormalities in patients with AOSD and evaluate the impact on the prognosis.Methods: A total number of 128 hospitalized patients, who met the Yamaguchi criteria of AOSD in the Department of Rheumatology and Immunology, Ruijin Hospital from July 2016 to August 2019 were consecutively enrolled and followed up. The demographic characteristics, clinical features, laboratory tests, treatments and prognosis were recorded. Correlations of liver function tests (LFTs) with disease activity and laboratory parameters were analyzed by the Spearman test. Risk factors of the refractory AOSD were evaluated by multivariate logistic regression analysis.Results: Liver involvement was presented in 104 (81.3%) patients with AOSD. We observed that 34 (32.7%) patients were with mild elevation, 32 (30.8%) patients were with moderate elevation, and 38 (36.5%) patients were with severe elevation. The majority of elevated ALT, AST and ALP decreased to normal within the range of 2 months, except for GGT. Furthermore, the LFTs were found significantly correlated with disease activity. Besides, we found patients with higher levels of LFTs tended to require more intensive treatments and suffered from poorer prognosis. Multivariate logistic regression analysis showed ALP ≥ 141 IU/L and GGT ≥ 132 IU/L are independent risk factors of refractory AOSD.Conclusion: Liver involvement is common in patients with AOSD, the levels of LFTs are associated with disease activity and related to the treatment strategies and prognosis.

Prevalence of liver injury and correlation with clinical outcomes in patients with COVID-19: systematic review with meta-analysis.

Liver involvement of SARS-CoV-2 infection has been reported in several papers, but without homogeneous findings. We aimed to systematically review the prevalence of liver involvement in patients with SARS-CoV-2 infection at their hospital admission, and its correlation with disease severity and clinical outcomes in patients with or without pre-existing chronic liver disease. We systematically searched PubMed, Embase, Web of Science, Medline, PMC, clinical trial registries, and other Coronavirus family publications for studies reporting data on SARS-CoV-2 infection or COVID-19 and liver function tests (LFTs) alterations, as well as clinical course of patients with chronic liver disease or cirrhosis. Case reports, preprints, editorials, reviews were excluded. We also revised literature to describe the background of liver involvement during SARS-CoV-2 infection. 36 studies, including 20724 patients with SARS-CoV-2 infection, were included. The pooled prevalence of LFTs abnormalities at admission was 46.9% (AST 26.5%, ALT 22.8%, GGT 22.5%, ALP 5.7%, tBIL 8.0%). ALT, AST, tBIL were independent predictors of disease severity (ALT OR 1.54, 95% CI 1.17-2.03; AST OR 3.17, 95% CI 2.10-4.77; tBIL OR 2.32, 95% CI 1.18-4.58) and in-hospital mortality (ALT OR 1.48, 95% CI 1.12-1.96; AST OR 4.39, 95% CI 2.68-7.18; tBIL OR 7.75, 95% CI 2.28-26.40). Heterogeneity among studies was high. The few available data also reported that COVID-19 was associated with increased risk of liver decompensation and mortality in patients with liver cirrhosis. LFTs alterations were reported in up to 47% of unselected patients with COVID-19 and were associated with severe disease or in-hospital mortality. In cirrhotic patients, COVID-19 was associated with high risk of liver decompensation or mortality.

Acute liver injury in a patient with adult-onset Still’s disease—the challenge of differential diagnosis

ABSTRACTIn addition to the cardinal symptoms of fever, rash and arthralgia, liver involvement in patients with adult-onset Still’s disease (AOSD) has been described. However, acute liver injury in AOSD patients can have various other causes: it can be a result of an AOSD-induced macrophage activation syndrome or be associated to the drugs given for the underlying diseases and symptoms. Differential diagnosis can therefore be challenging. We here present a case of a 32-year-old male with acute liver injury following the initial diagnosis of AOSD to discuss the possible underlying reasons.
