Minimal Hepatic Encephalopathy
Minimal hepatic encephalopathy (MHE) is the earliest form of hepatic encephalopathy and can affect up to 80% of cirrhotic patients. By definition, it has no obvious clinical manifestation and is characterized by neurocognitive impairment in attention, vigilance and integrative function. Although often not considered to be clinically relevant and, therefore, not diagnosed or treated, MHE has been shown to affect daily functioning, quality of life, driving and overall mortality. The diagnosis of MHE has traditionally been achieved through neuropsychological examination, psychometric tests or the newer critical flicker frequency test. A new smartphone application (EncephalApp Stroop Test) may serve to function as a screening tool for patients requiring further testing. In addition to physician reporting and driving restrictions, medical treatment for MHE includes non-absorbable disaccharides (eg, lactulose), probiotics or rifaximin. Liver transplantation may not result in reversal of the cognitive deficits associated with MHE
Challenges in PARP inhibitor therapy: A case of Olaparib-induced liver injury and successful rechallenge with Niraparib
Olaparib, the first-in-class poly ADP-ribose polymerase (PARP) inhibitor, is approved for first line maintenance treatment in platinum-sensitive FIGO stage 3 and 4 high grade serous ovarian cancer (HGSOC) associated with a deleterious BRCA mutation. We report a case involving a 70-year-old female who experienced significant CTCAE Grade 4 hepatocellular injury after initiating first line maintenance Olaparib for Stage 3C HGSOC. Her liver injury resolved upon discontinuation of Olaparib but promptly recurred upon rechallenge. Extensive investigations, including abdominal ultrasound, computed tomography, and assessments for infectious, metabolic, and autoimmune aetiologies of liver injury, were unremarkable. Her liver enzymes returned to baseline after discontinuing Olaparib once again. Subsequently, the patient was started on Niraparib for maintenance therapy, which she tolerated well. This case represents the first instance of positive rechallenge following Olaparib-induced liver injury and highlights the absence of cross-reactive hepatotoxicity between PARP inhibitors

Noninvasive Markers of Fibrosis and Inflammation in Nonalcoholic Fatty Liver Disease
The prevalence of nonalcoholic fatty liver disease (NAFLD) is increasing worldwide. Nonalcoholic steatohepatitis (NASH) and fibrosis are associated with elevated morbidity and mortality, and a means of differentiating these diseases from simple steatosis (SS) is needed. Liver biopsy in all patients with NAFLD is not feasible, thus necessitating a noninvasive method for discerning the presence of inflammation and fibrosis. Of the various serum markers, cytokeratin-18 seems to best predict NASH, the NAFLD Fibrosis Score is most closely correlated with fibrosis, and transient elastography can be used for diagnosis of cirrhosis, or to exclude cirrhosis, although its utility is limited by obesity
Pharmaceutical characterization and exploration of Arkeshwara rasa in MDA-MB-231 cells.
BACKGROUND
The diverse specificity mode of cancer treatment targets and chemo resistance demands the necessity of drug entities which can address the devastating dynamicity of the disease.
OBJECTIVES
To check the anti-tumour potential of traditional medicine rich in polyherbal components and metal nanoparticle namely Arkeshwara rasa (AR).
MATERIAL METHODS
The AR was prepared in a modified version with reference from Rasaratna Samuchaya and characterized using sophisticated instrumental analysis including XRD, SEM-EDAX, TEM, TGA-DSC, and LC-MS and tested against the MDA-MB-231 cell line to screen cell viability and the cytotoxicity with MTT, SRB and the AO assay.
RESULTS
XRD pattern shows cubic tetrahedrite structure with Sb, Cu, S peaks and trace elements like Fe, Mg, etc. The particle size of AR ranges between 20 and 30 nm. The TGA points thermal decomposition at 210 °C and the metal sulphide peaks in DSC. LC-MS analysis reveals the components of the formulation more on the flavonoid portion. The IC50 value of MTT and SRB are 25.28 μg/mL and 31.7 μg/mL respectively. The AO colorimeter substantiated the cell viability and the apoptosis figures of the same cell line. The AR exhibits cytotoxicity and reaffirms the apoptosis fraction with SRB assay.
CONCLUSIONS
The Hesperidine, Neohesperidin, Rutin components in the phytochemical pool can synergize the anti-tumour potential with either influencing cellular pathways or decreasing chemo resistance to conventional treatment. AR need to be further experimented with reverse transcription, flow cytometry, western blotting, etc
