Long-term outcome of Wilson's disease complicated by liver disease.

ABSTRACT:

Background and aim

Wilson's disease (WD) is a rare inherited disease that causes systemic copper accumulation. This study examined the long-term course of WD patients with liver disease.

Methods

The 12 patients (9 female patients) enrolled in the study had a median age of 28 years (range: 19-57 years) at their first visit to our hospital. Clinical course and fibrosis markers were assessed in all patients.

Results

The median age at diagnosis was 24 years (range: 5-42 years). One patient had acute liver failure (ALF) and 11 patients had chronic liver disease (CLD, 5 with cirrhosis). The patients were followed-up for >20 years. The patient with ALF underwent liver transplantation; the postoperative course during the subsequent 20 years was good. Of the six patients with CLD, liver cirrhosis developed in four patients with interrupted chelating therapy. Two of the patients with cirrhosis died; one of these two patients died at 21 years after liver transplantation. However, the remaining patients with continued treatment exhibited a favorable clinical course for 30 years and none developed hepatocellular carcinoma (HCC). The duration of chelation therapy was significantly negatively correlated (P < 0.05) with the fibrosis-4 index or aspartate aminotransferase to platelet ratio index (APRI) score at the last visit; lower values were indicative of greater treatment success. Patients with an APRI score ≥1.5 had a significantly worse prognosis (P < 0.05).

Conclusion

Long-term survival of patients with WD was achieved without worsened liver function or carcinogenesis with appropriate treatment. Treatment disruption should be avoided.

SGLT2 Inhibitor Treatment Outcome in Nonalcoholic Fatty Liver Disease Complicated with Diabetes Mellitus: The Long-term Effects on Clinical Features and Liver Histopathology.

Project description:Objective The aim of this study was to determine the long-term effects of a sodium-glucose cotransporter 2 inhibitor (SGLT2i) in nonalcoholic fatty liver disease (NAFLD) patients with type 2 diabetes mellitus (T2DM) on the clinical features and liver histopathology. Methods In this retrospective study, the long-term histological impacts of SGLT2i in NAFLD patients with T2DM were investigated. Patients Seven patients with NAFLD and T2DM were treated for the long term with 100 mg/day canagliflozin, an SGLT2i, and liver biopsies were obtained at the 3 points of pretreatment, 24 weeks, and ≥1 year (third liver biopsy) after the start of treatment. Six of seven patients were evaluated with third liver biopsy at the point of three or more years. The primary outcome was liver histopathological changes (defined as a decrease in the NAFLD activity score of one point or more without worsening of the fibrosis stage, compared to pretreatment). Results All 7 patients showed worsening of body mass index and waist circumference at the third liver biopsy compared to 24 weeks. However, the scores of steatosis, lobular inflammation, ballooning, and fibrosis stage improved at the third liver biopsy in 57%, 43%, 14%, and 29% of the patients, respectively, compared to pretreatment. One of the seven patients showed histopathological worsening at the third liver biopsy compared to pretreatment, but the improvement was maintained in the other six patients. Conclusion The long-term treatment of NAFLD complicated by T2DM using an SGLT2i is associated with long-term improvement in liver histopathology despite the worsening of clinical features.

Elastography of the Liver in Wilson's Disease.

Project description:Staging of liver fibrosis is of special significance in Wilson's disease as it determines the patient's prognosis and treatment. Histopathological examination is a standard method for fibrosis assessment; however, non-invasive methods like transient elastography and share wave elastography are believed to be reliable and repetitive and are expected to replace liver biopsy in Wilson's disease. This article presents a short description of available elastography techniques and the results of the most recent studies on elastography of the liver in patients with Wilson's disease.

Mesenchymal iron deposition is associated with adverse long-term outcome in non-alcoholic fatty liver disease.

Project description:Background & aimsApproximately one-third of patients with non-alcoholic fatty liver disease (NAFLD) show signs of mild-to-moderate iron overload. The impact of histological iron deposition on the clinical course of patients with NAFLD has not been established.Methods & resultsFor this retrospective study, 299 consecutive patients with biopsy-proven NAFLD and a mean follow-up of 8.4 (±4.1; range: 0.3-18.0) years were allocated to one of four groups according to presence of hepatic iron in the reticuloendothelial system (RES) and/or hepatocytes (HC): 156 subjects (52%) showed no stainable iron (NONE), 58 (19%) exclusively reticuloendothelial (xRES), 19 (6%) exclusively hepatocellular (xHC) and 66 (22%) showed a mixed (HC/RES) pattern of iron deposition. A long-term analysis for overall survival, hepatic, cardiovascular or extrahepatic-malignant events was conducted. Based on multivariate Cox proportional hazards models any reticuloendothelial iron was associated with fatal and non-fatal hepatic events. Specifically, xRES showed a cause-specific hazard ratio (csHR) of 2.4 (95%-CI, 1.0-5.8; P = .048) for hepatic as well as cardiovascular fatal and non-fatal events combined (csHR 3.2; 95%-CI, 1.2-8.2; P = .015). Furthermore, the mixed HC/RES iron pattern showed a higher rate of combined hepatic fatal and non-fatal events (csHR 3.6; 95%-CI, 1.4-9.5; P = .010), while xHC iron deposition was not associated with any defined events.ConclusionsThe presence of reticuloendothelial-accentuated hepatic iron distribution patterns is associated with detrimental long-term outcomes reflected in a higher rate of both liver-related and cardiovascular fatal and non-fatal events.

Correction of copper metabolism is not sustained long term in Wilson's disease mice post bone marrow transplantation.

Project description:PURPOSE: Alternative cell sources have been sought for the treatment of liver diseases, since liver cells are in short supply for cell transplantation. Although bone marrow-derived cells have been investigated as an alternative cell source, few studies have demonstrated long-term disease correction. Here we examined bone marrow stem cell transplantation into the toxic milk (tx) mouse model for Wilson's disease, a mild liver disease characterized by hepatic copper accumulation. The aim of this study was to determine whether bone marrow cells engrafted in the liver could sustain correction of abnormal copper metabolism in the tx mouse. METHODS: Bone marrow cells were isolated from congenic normal mice, transduced to express enhanced green fluorescent protein, sorted for stem cell (Sca-1) and lineage cell (Lin) surface markers, and then transplanted into sub-lethally irradiated normal or tx mice. Analysis for donor cell activity and distribution was undertaken 5 and 9 months post-transplant to allow for sufficient time to repopulate the liver and demonstrate disease correction. RESULTS: Donor bone marrow cells engrafted in both normal and tx mouse liver within 5 months. Significantly reduced liver copper was found in tx mice with donor cell liver engraftment at 5 months post-transplant compared to controls, demonstrating partial correction of abnormal copper metabolism in the short term. However, disease correction was not maintained 9 months post-transplantation. Lin(-)Sca-1(+) cells were more likely to partially correct disease than Lin(+)Sca-1(-) cells in the short term. CONCLUSION: These results demonstrate that bone marrow transplants cannot maintain disease correction in a mouse model of mild hepatic damage, although initial copper metabolism correction was observed.

Zinc as a Drug for Wilson's Disease, Non-Alcoholic Liver Disease and COVID-19-Related Liver Injury.

Project description:Zinc is the second most abundant trace element in the human body, and it plays a fundamental role in human physiology, being an integral component of hundreds of enzymes and transcription factors. The discovery that zinc atoms may compete with copper for their absorption in the gastrointestinal tract let to introduce zinc in the therapy of Wilson's disease, a congenital disorder of copper metabolism characterized by a systemic copper storage. Nowadays, zinc salts are considered one of the best therapeutic approach in patients affected by Wilson's disease. On the basis of the similarities, at histological level, between Wilson's disease and non-alcoholic liver disease, zinc has been successfully introduced in the therapy of non-alcoholic liver disease, with positive effects both on insulin resistance and oxidative stress. Recently, zinc deficiency has been indicated as a possible factor responsible for the susceptibility of elderly patients to undergo infection by SARS-CoV-2, the coronavirus responsible for the COVID-19 pandemic. Here, we present the data correlating zinc deficiency with the insurgence and progression of Covid-19 with low zinc levels associated with severe disease states. Finally, the relevance of zinc supplementation in aged people at risk for SARS-CoV-2 is underlined, with the aim that the zinc-based drug, classically used in the treatment of copper overload, might be recorded as one of the tools reducing the mortality of COVID-19, particularly in elderly people.

Long-Term Treatment Outcome of Progressive Mycobacterium Avium Complex Pulmonary Disease.

Project description:BACKGROUND:Multidrug therapy is essential for preventing respiratory failure in patients with highly progressive Mycobacterium avium complex pulmonary disease (MAC-PD). However, the prognosis and long-term outcome following combination therapy is poorly understood. METHODS:We retrospectively evaluated the clinical characteristics and long-term outcomes in patients with chemo-naïve progressive MAC-PD, hospitalized for first-line multidrug therapy. RESULTS:Among 125 patients, 86 (68.8%) received standardized treatment (rifampicin, ethambutol, clarithromycin), 25 (20.0%) received a fluoroquinolone (FQ)-containing regimen, and 53 (42.4%) received aminoglycoside injection. The sputum conversion rate was 80.0%, and was independently associated with standardized treatment. The incidence of refractory disease (45.6%) was independently and negatively associated with standardized regimen and aminoglycoside use. Choice of an FQ-containing regimen was not associated with positive outcome. Clarithromycin resistance occurred in 16.8% and was independently associated with refractory disease. MAC-PD-associated death occurred in 3.3% of patients with non-cavitary nodular bronchiectasis (NB) and 21.3% with cavitary MAC-PD over a median follow-up period of 56.4 months. The rates of MAC-PD-associated death were comparable between cavitary-NB and fibrocavitary disease. Concurrent chronic pulmonary aspergillosis (CPA) occurred in 13 (17.3%) patients with cavitary MAC-PD, and age, diabetes mellitus, and CPA were independent risk factors for mortality. CONCLUSIONS:Standardized intensive multidrug treatment reduces disease progression and persistence in progressive MAC-PD. Cavitary NB may differ from, rather than being just an advanced stage of, non-cavitary NB. The high incidence and significant mortality of CPA in cavitary MAC-PD highlight the need for early diagnosis and treatment.

Long-term efficacy and safety of nalfurafine hydrochloride on pruritus in chronic liver disease patients: Patient-reported outcome based analyses.

Project description:BACKGROUND AND AIM:Among various symptoms accompanied with chronic liver disease, pruritus affects the quality of life of patients, causing physical and mental stress, and worsens hepatic function. Recently, ?-opioid receptor agonist, nalfurafine hydrochloride was approved to treat central pruritus in patients with liver disease in Japan. This study aimed to assess the long-term efficacy and safety of nalfurafine hydrochloride on pruritus in chronic liver disease patients. METHODS:A patient-reported outcome using questionnaire-based methods was used for 41 liver disease patients with or without pruritus symptoms. Nalfurafine hydrochloride (2.5 ?g/day) was orally administered to 18 patients suffering from pruritus symptoms and whose current treatment was not effective. The same questionnaires and visual analogue scales (VAS) were repeatedly followed up for the patients for the entire follow-up period, and biochemical analyses were performed to evaluate the safety of the treatment. RESULTS:Pruritus completely disappeared in seven of 18 cases, and VAS scores showed a decreasing trend over time from the start of nalfurafine hydrochloride administration in all patients who received the medication. Among 11 patients who were followed up for more than 12 weeks, nine patients showed continuous improvement of symptoms, and this progress was still apparent at ?20 weeks after starting administration (p < 0.0001). The medication was discontinued in four patients because of progression of primary disease, high cost, oral dryness, and anemia. No significant toxicity was observed on the serum biochemical analyses. CONCLUSIONS:Nalfurafine hydrochloride contributed to long-term suppression of pruritus without significant safety problems.

Metabolic Dysfunction-Associated Fatty Liver Disease Predicts Long-term Mortality and Cardiovascular Disease.

Project description:Background/aimsWe investigated the effect of metabolic dysfunction-associated fatty liver disease (MAFLD) on future mortality and cardiovascular disease (CVD) using a prospective community-based cohort study.MethodsIndividuals from two community-based cohorts who were 40 to 70 years old were prospectively followed for 16 years. MAFLD was defined as a high fatty liver index (FLI ≥60) plus one of the following conditions: overweight/obesity (body mass index ≥23 kg/m2), type 2 diabetes mellitus, or ≥2 metabolic risk abnormalities. Nonalcoholic fatty liver disease (NAFLD) was defined as FLI ≥60 without any secondary cause of hepatic steatosis.ResultsAmong 8,919 subjects (age 52.2±8.9 years, 47.7% of males), 1,509 (16.9%) had MAFLD. During the median follow-up of 15.7 years, MAFLD independently predicted overall mortality after adjustment for confounders (hazard ratio [HR], 1.33; 95% confidence interval [CI], 1.05 to 1.69) but NAFLD did not (HR, 1.20; 95% CI, 0.94 to 1.53). MAFLD also predicted CVD after adjustment for age, sex, and body mass index (HR, 1.35; 95% CI, 1.13 to 1.62), which lost its statistical significance by further adjustments. Stratified analysis indicated that metabolic dysfunction contributed to mortality (HR, 1.51; 95% CI, 1.21 to 1.89) and CVD (HR, 1.27; 95% CI, 1.02 to 1.59). Among metabolic dysfunctions used for defining MAFLD, type 2 diabetes mellitus in MAFLD increased the risk of both mortality (HR, 2.07; 95% CI, 1.52 to 2.81) and CVD (HR, 1.42; 95% CI, 1.09 to 1.85).ConclusionsMAFLD independently increased overall mortality. Heterogeneity in mortality and CVD risk of subjects with MAFLD may be determined by the accompanying metabolic dysfunctions.

Long-term outcome in patients after treatment for Cushing's disease in childhood.

Project description:INTRODUCTION:Cushing's disease (CD) is a rare cause of hypercortisolemia presenting a major diagnostic and therapeutic challenge. Data on pituitary function in long-term follow-up after CD treatment in childhood is limited. AIM:Long-term assessment of patients of the Children's Memorial Health Institute (CMHI) after CD treatment in childhood. MATERIALS AND METHODS:Retrospective analysis of 29 CD patients, mean age at the time of diagnosis 13.46 yrs. The long-term follow-up (FU) was done by: 1) obtaining the data from a patient's questionnaire (75% of adult patients); 2) using the data from the last clinic visit for patients who did not respond to the questionnaire and for current CMHI patients. The average long-term FU from transsphenoidal pituitary surgery (TSS) was 10.23 yrs. RESULTS:At the latest FU: 18 patients (62%) had long-term disease remission after TSS1, 2 patients (6.9%) after TSS2, 1 patient (3.4%) after the post-TSS radiotherapy (XRT) cycle and 3 patients (10.3%) after bilateral adrenalectomy (BA). One patient (3.4%) died after TSS2 due to postoperative complications, 1 patient (3.4%) had persistent disease at latest FU, in 1 patient (3.4%) the long-term FU was not possible to perform. CD recurrence occurred in 4 out of 28 patients (14%) at an average time 3.6 yrs. from definitive treatment. One patient (3.4%) after BA was operated because of Nelson's syndrome. Two patients (6.9%) were suspected of relapse at latest assessment. At the time of the last evaluation, 17 patients (63%) were on levothyroxine therapy since definitive treatment, 16 patients (59%) were on hydrocortisone treatment, 10 patients (37%) were taking sex hormones replacement, 4 patients (15%)-antidiuretic hormone. CONCLUSIONS:Relatively large number of patients after CD treatment in childhood have hormonal pituitary deficits as well as mood and cognitive disorders. CD recurrence can occur even after a long time post effective treatment.

Wilson's disease: changes in methionine metabolism and inflammation affect global DNA methylation in early liver disease.

Project description:Hepatic methionine metabolism may play an essential role in regulating methylation status and liver injury in Wilson's disease (WD) through the inhibition of S-adenosylhomocysteine hydrolase (SAHH) by copper (Cu) and the consequent accumulation of S-adenosylhomocysteine (SAH). We studied the transcript levels of selected genes related to liver injury, levels of SAHH, SAH, DNA methyltransferases genes (Dnmt1, Dnmt3a, Dnmt3b), and global DNA methylation in the tx-j mouse (tx-j), an animal model of WD. Findings were compared to those in control C3H mice, and in response to Cu chelation by penicillamine (PCA) and dietary supplementation of the methyl donor betaine to modulate inflammatory and methylation status. Transcript levels of selected genes related to endoplasmic reticulum stress, lipid synthesis, and fatty acid oxidation were down-regulated at baseline in tx-j mice, further down-regulated in response to PCA, and showed little to no response to betaine. Hepatic Sahh transcript and protein levels were reduced in tx-j mice with consequent increase of SAH levels. Hepatic Cu accumulation was associated with inflammation, as indicated by histopathology and elevated serum alanine aminotransferase (ALT) and liver tumor necrosis factor alpha (Tnf-?) levels. Dnmt3b was down-regulated in tx-j mice together with global DNA hypomethylation. PCA treatment of tx-j mice reduced Tnf-? and ALT levels, betaine treatment increased S-adenosylmethionine and up-regulated Dnmt3b levels, and both treatments restored global DNA methylation levels.Reduced hepatic Sahh expression was associated with increased liver SAH levels in the tx-j model of WD, with consequent global DNA hypomethylation. Increased global DNA methylation was achieved by reducing inflammation by Cu chelation or by providing methyl groups. We propose that increased SAH levels and inflammation affect widespread epigenetic regulation of gene expression in WD.
