Abstract
Nonalcoholic fatty liver disease (NAFLD) has become the most prevalent chronic liver disease worldwide. Minerals including iron, copper, zinc, and selenium, fulfil an essential role in various biochemical processes. Moreover, the identification of ferroptosis and cuproptosis further underscores the importance of intracellular mineral homeostasis. However, perturbation of minerals has been frequently reported in patients with NAFLD and related diseases. Interestingly, studies have attempted to establish an association between mineral disorders and NAFLD pathological features, including oxidative stress, mitochondrial dysfunction, inflammatory response, and fibrogenesis. In this review, we aim to provide an overview of the current understanding of mineral metabolism (i.e., absorption, utilization, and transport) and mineral interactions in the pathogenesis of NAFLD. More importantly, this review highlights potential therapeutic strategies, challenges, future directions for targeting mineral metabolism in the treatment of NAFLD.

ARQUIVOS DE GASTROENTEROLOGIA 2021; 57:249-253. [PMID: 32935743 DOI: 10.1590/s0004-2803.202000000-47] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/04/2020] [Accepted: 06/05/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Copper deficiency has been linked to alterations in lipid metabolism and hepatic steatosis. Oxidative stress plays a role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). One of the enzymes that neutralize oxidative stress is Cu/Zn superoxide dismutase, which depends on the availability of adequate amounts of copper. OBJECTIVE Correlate the levels of ceruloplasmin and of non-ceruloplasmin-bound copper (NCBC) with clinical, biochemical and histological parameters of non-alcoholic fatty liver disease (NAFLD) patients. METHODS Data from 95 consecutively admitted NAFLD patients who underwent liver biopsy composed the groups based on ceruloplasmin levels lower than 25 mg/dL and on negative NCBC. The risk factors for NAFLD in each group were compared. RESULTS Body mass index was lower in patients with ceruloplasmin <25 mg/dL (29.1±3.47 vs 32.8±6.24 kg/m2; P=0.005) as were the levels of LDL, HDL and total cholesterol, when compared with their counterparts with ceruloplasmin >25 mg/dL (101±38 vs 116±35 mg/dL, P=0.05; 43±9 vs 51±16 mg/dL, P=0.01; 174±43 vs 197±39 mg/dL, P=0.01, respectively). Mean serum ferritin levels were higher in the ceruloplasmin <25 mg/dL group (343±327 vs 197±190 ng/mL; P=0.02). Otherwise, patients with negative NCBC had higher HOMA-IR (8.2±14.7 vs 4.6±3.7; P=0.03). Age, gender, hypertension and diabetes showed no statistical difference. CONCLUSION Patients with NAFLD had different clinical and biochemical markers according to the levels of NCBC and ceruloplasmin.

Abstract
Copper, an essential micronutrient, is required for lipid metabolism, mitochondrial function, iron metabolism, and antioxidant defense. Copper deficiency has been linked to alterations in lipid metabolism and various metabolic processes of the liver, including nonalcoholic fatty liver disease (NAFLD); however, most of these studies relied on copper measurements in the blood or tissues. In this study, we investigated the association between hair copper concentration and NAFLD in Korean adults, independent of metabolic syndrome status. Clinical and laboratory parameters, including factors of metabolic syndrome, were analyzed in 751 Korean adults divided into quintiles, according to hair copper concentration. Lower hair copper concentration was significantly correlated with higher body mass index, waist circumference, blood pressure, and lower levels of high-density lipoprotein cholesterol. Subjects with NAFLD showed significantly lower hair copper concentrations, and the risk of NAFLD was significantly higher for the lower hair copper quintile groups even after adjusting for metabolic syndrome-related factors. Overall, this study suggests that lower hair copper concentration could be associated with NAFLD, independent of metabolic syndrome factors.

Abstract
Considerable attention has been focused on nonalcoholic fatty liver disease (NAFLD) which occasionally develops after pancreatoduodenectomy (PD). The present study aimed to clarify the prevalence, sequential change in properties and risk factors for NAFLD development after PD. We enrolled 196 patients who underwent PD and a computed tomography (CT) scan 1 month, 6 months and 1 year after surgery. NAFLD was defined as a liver‐to‐spleen attenuation ratio on plain CT of <0.9. We compared various clinical factors between the NAFLD group and the control group. Individual prevalence of NAFLD at 1 month, 6 months and 1 year after surgery was 12%, 21% and 15%. Significantly different factors by univariate analysis were as follows: 1 month: age, sex, total protein (TP), total cholesterol (TC) and copper (Cu); 6 months: sex, disease, surgical method, portal vein resection (PVR), frequency of defecation, TC and Cu; 1 year: age, sex, disease, surgical method, PVR, frequency of defecation, TP and Cu. Risk factors by multivariate analysis were as follows: 1 month: not elderly age, female sex and a decrease in Cu; 6 months: female sex and a decrease in Cu; 1 year: a decrease in Cu. NAFLD after PD frequently developed in women with a decrease in serum Cu and was influenced by various factors related to poor digestion and absorption associated with pancreatic exocrine insufficiency.

Low hepatic copper content and PNPLA3 polymorphism in non-alcoholic fatty liver disease in patients without metabolic syndrome. J Trace Elem Med Biol 2017; 39:100-107. [PMID: 27908400 DOI: 10.1016/j.jtemb.2016.08.006] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2016] [Revised: 08/02/2016] [Accepted: 08/18/2016] [Indexed: 12/18/2022]
Abstract
INTRODUCTION The pathogenesis of non-alcoholic fatty liver disease (NAFLD) is multifactorial including metabolic, genetic (e.g. PNPLA3 [patatin-like phospholipase domain-containing 3 gene]), viral factors and drugs. Besides, there is evidence for a role of copper deficiency. Aim of the study was to evaluate the role of hepatic copper content, PNPLA3 in NAFLD patients with and without metabolic syndrome (MetS). METHODS One-hundred seventy-four NAFLD patients, who underwent liver biopsy for diagnostic work-up, were studied. Diagnosis of MetS was based on the WHO Clinical Criteria. Steatosis was semiquantified as percentage of fat containing hepatocytes and was graded according to Brunt. Histological features of non-alcoholic steatohepatitis (NASH) were assessed using the Bedossa classification. Hepatic copper content (in μg/g dry weight) was measured by flame atomic absorption spectroscopy. SNP rs738409 in PNPLA3 was investigated by RT-PCR. RESULTS Mean hepatic copper content was 22.3 (19.6-25.1) μg/g. The mean percentage of histologically lipid containing hepatocytes was 42.2% (38.3-46.0) and correlated inversely with hepatic copper content (ρ=-0.358, P<0.001). By subgroup analysis this inverse correlation remained significant only in patients without MetS (OR: 0.959 [CI95%: 0.926-0.944], P=0.020). Presence of minor allele (G) of PNPLA3 was also associated with moderate/severe steatosis (≥33%) both in patients with (OR: 2.405 [CI95%: 1.220-4.744], P=0.011) and without MetS (OR: 2.481 [CI95%: 1.172-5.250], P=0.018), but was only associated with NASH (OR: 2.002 [CI95%: 1.062-3.772], P=0.032) and liver fibrosis (OR: 2.646 [CI95%: 1.299-5.389], P=0.007) in patients without MetS. CONCLUSION Hepatic copper content and PNPLA3 mutations are associated with disease activity in NAFLD patients without MetS. Presence of MetS appears to mask the effects of hepatic copper and PNPLA3.
