BMC Endocr Disord 2023; 23:11. [PMID: 36627697 PMCID: PMC9830772 DOI: 10.1186/s12902-022-01234-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Accepted: 11/30/2022] [Indexed: 01/12/2023] Open
Abstract
We investigated the prevalence and clinical metabolic characteristics of lean nonalcoholic fatty liver disease (NAFLD) in an elderly Chinese population and assessed the relevance of lipid markers and genetic variation. All 5,338 community subjects underwent detailed clinical and laboratory examinations and were divided into three groups: lean (Body mass index (BMI) < 23 kg/m2, n = 2,012), overweight (BMI = 23-24.9 kg/m2, n = 1,354), and obese (BMI ≥ 25 kg/m2, n = 1,972). Single nucleotide polymorphisms were selected based on those reported in previous NAFLD or obesity genome-wide association studies. The frequencies of alleles and genotypes were calculated and statistically analyzed with Pearson's χ2 tests. One-way ANCOVA was used to test the association between positive SNPs and metabolic parameters in lean NAFLD individuals. Our results showed that the C allele frequency of rs2279026, the G allele of rs2279028, the C allele of rs780093, and the C allele frequency of rs1260326 were higher in obese NAFLD than in lean NAFLD (P < 0.05). In addition, we observed an association between the CC of rs1421085, TT of rs3751812, AA of rs8050136, and AA of rs9939609 genotypes in the FTO gene and low-density lipoprotein levels (P < 0.05). In conclusion, our findings provide a unique perspective on the prevalence, genetic characteristics, and metabolic profile of NAFLD in older lean individuals in China. This is the first study to examine the association between genetic variants in the FTO, TFAP2B and GCKR genes and NAFLD in a cohort of lean individuals.

World J Clin Cases 2022; 10:6211-6217. [PMID: 35949851 PMCID: PMC9254213 DOI: 10.12998/wjcc.v10.i18.6211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2021] [Revised: 03/25/2022] [Accepted: 04/22/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Craniopharyngioma is a benign tumor that usually develops in children; however, it is located in the center and close to sensitive structures, such as the pituitary gland and hypothalamus. As the hypothalamus plays a crucial role in the homeostasis of anterior pituitary hormone synthesis, damage to the hypothalamus leads to multiple pituitary hormone deficiencies and non-alcoholic fatty liver disease, including hepatopulmonary syndrome (HPS). HPS has limited treatment and poor prognosis.
CASE SUMMARY A girl aged 13 years and 6 mo underwent surgery for craniopharyngioma 6 years prior. Right craniotomy was performed with total resection via the corpus callosum approach, and the tumor at the base was approximately 3.5 cm × 3.5 cm × 4.0 cm. At 1 year postoperatively, she exhibited abdominal distension and weakness, and the laboratory tests revealed fatty liver disease. Thereafter, she had not visited the outpatient clinic for 2 years. Two years ago, she developed decreased activity endurance, severe cyanosis, chest tightness, wheezing, and intermittent and recurrent low fever after mild physical labor. Hepatobiliary ultrasonography, liver biopsy, and contrast echocardiography of the right heart showed cirrhosis and multiple pituitary hormone deficiencies, indicating HPS. After 1 year of treatment with recombinant human growth hormone, the liver function and oxygenation improved; she did not undergo liver transplantation.
CONCLUSION Craniopharyngioma surgery can easily cause hypopituitarism, which can lead to nonalcoholic steatohepatitis and HPS in children. Early growth hormone therapy is important to improve the prognosis of these diseases.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the commonest cause of chronic liver disease worldwide. It is closely related to obesity, insulin resistance (IR) and dyslipidemia so much so it is considered the hepatic manifestation of the Metabolic Syndrome. The NAFLD spectrum extends from simple steatosis to nonalcoholic steatohepatitis (NASH), a clinical condition which may progress up to fibrosis, cirrhosis and hepatocellular carcinoma (HCC). NAFLD is a complex disease whose pathogenesis is shaped by both environmental and genetic factors. In the last two decades, several heritable modifications in genes influencing hepatic lipid remodeling, and mitochondrial oxidative status have been emerged as predictors of progressive hepatic damage. Among them, the patatin-like phospholipase domain-containing 3 (PNPLA3) p.I148M, the Transmembrane 6 superfamily member 2 (TM6SF2) p.E167K and the rs641738 membrane bound-o-acyltransferase domain-containing 7 (MBOAT7) polymorphisms are considered the most robust modifiers of NAFLD. However, a forefront frontier in the study of NAFLD heritability is to postulate score-based strategy, building polygenic risk scores (PRS), which aggregate the most relevant genetic determinants of NAFLD and biochemical parameters, with the purpose to foresee patients with greater risk of severe NAFLD, guaranteeing the most highly predictive value, the best diagnostic accuracy and the more precise individualized therapy.
