Previous studies have reported that metabolic syndrome (MetS) is associated with an increased risk of major cardiovascular events and levels of C-Reactive protein (CRP) can be considered as markers of MetS and its constituent components. Oxidative stress plays a major role in the development of MetS, and levels of gamma-glutamyl transferase (GGT) change with response to oxidative stress are also associated with MetS, which may be modulated by CRP. This study was conducted to identify the role of GGT and CRP as biomarkers in the diagnosis of MetS, a high-risk factor for cardiovascular diseases. One hundred and fifty patients meeting the diagnostic criteria of MetS and an equal number of controls were included in the study. The cases were selected from pathology and molecular biology laboratories, Karachi, while the controls came from the general population. Anthropometric indices of adiposity and blood pressure were recorded for both cases and controls. Blood samples were taken from all subjects to determine the levels of CRP and GGT. All those cases and control height, weight, hip waist circumference were noted and the comparison of CRP and GGT by applying students' t-test as markers for detection of metabolic syndrome. p-value 0.001 was considered as significant. This study suggests that in patients with metabolic syndrome were found to have raised the basal metabolic rate, C-reactive protein and GGT were synergistically associated with MetS independently of another confounding factor in the general population. Keywords: C-reactive protein (CRP), gama glutamyl transferase (GGT), metabolic syndrome, (Met-S), inflammation, body mass index.

Liver size in mammals fluctuates throughout the day and correlates with changes in hepatocyte size. However, the role of these daily changes in liver and hepatocyte size and the underlying molecular mechanisms remain largely unknown. In this review, we highlight the view that hepatocyte size, and thus, overall organ size, is subject to regulation by the circadian clock and feeding/fasting cycles. To that end, we provide an overview of the current literature dealing with this phenomenon and elaborate the role of feeding and nutrients in this process. We will discuss the role of hepatic protein content and synthesis, which are both subject to diurnal regulation, in daily hepatocyte and liver size fluctuations. Although there is evidence that changes in hepatocyte and liver size are associated with daily variations in macromolecule content, there is also evidence that these changes in size may be actively regulated by modifications of the cells' osmotic environment. Future research will need to examine the intriguing possibility that hepatocyte and liver size fluctuations may be required for normal liver function and to reveal the underlying molecular mechanisms behind this process.

Abstract Background: Liver function derangements have been reported in coronavirus disease (COVID-19) but reported rates are variable. Methods: We searched Pubmed and Embase with terms COVID and SARS-COV-2 from December 1, 2019 till April 5, 2020. We estimated overall prevalence, stratified prevalence based on severity, estimated risk ratio (RR) and estimated standardized mean difference (SMD) of liver function parameters in severe as compared to nonsevere COVID. Random effect method utilizing inverse variance approach was used for pooling the data. Results: In all, 128 studies were included. The most frequent abnormalities were hypoalbuminemia [61.27% (48.24 - 72.87)], elevations of gamma-glutamyl transferase (GGT) [27.94%(18.22 -40.27)], alanine aminotransferase (ALT) [23.28%(19.92 - 27.01)] and aspartate aminotransferase (AST) [23.41%(18.84 - 28.70)]. Further the relative risk of these abnormalities was higher in the patients with severe COVID-19 when compared to non-severe disease [Hypoalbuminemia - 2.65(1.38 - 5.07); GGT - 2.31(1.6 - 3.33); ALT - 1.76(1.44 - 2.15); AST 2.30(1.82 - 2.90)]. The SMD of hypoalbuminemia, GGT, ALT and AST elevation in severe as compared to nonsevere were -1.05(-1.27 - -0.83), 0.76(0.40 - 1.12), 0.42(0.27 - 0.56) and 0.69 (0.52 - 0.86) respectively. The pooled prevalence and RR of chronic liver disease as a comorbidity was 2.64% (1.73- 4) and 1.69(1.05-2.73) respectively. Conclusion: The most frequent abnormality in liver functions was hypoalbuminemia followed by derangements in gamma-glutamyl transferase and aminotransferases and these abnormalities were more frequent in severe disease. The systematic review was, however, limited by heterogeneity in definitions of severity and liver function derangements.
