Despite the appearance of the direct acting antiviral drugs, pegylated interferon/ribavirin (PEG-IFN/RBV) still has a place in the standard of care (SOC) therapy for chronic HCV4. Studies were conducted to find an accurate prediction in response to SOC therapy. Pretreatment serum interferon-γ-inducible protein-10 (IP-10) is an independent predictive factor of sustained virological response (SVR) in HCV1-infected patients. To assess whether the pretreatment serum level of IP-10 influences hepatic fibrosis and PEG-IFN/RBV therapy response, a study was conducted on 88 chronic Hepatitis C virus (HCV) patients who received PEG-IFN/RBV. Patients were subjected to a pretreatment routine laboratory evaluation, liver biopsy, and serum IP-10 assessment. They were followed up for 6 months after cessation of therapy (week 72). Patients were classified into 3 groups according to their response; nonresponders, relapsers, or sustained virological responders. The relation of pretreatment IP-10 with fibrosis and response was assessed. The studied groups were matched regarding their demographic data. There was no statistically significant association between the pretreatment IP-10 level and fibrosis (P=0.86) and no relation to response was found at week 12, 24, 48, and 72 (P=0.58, 0.8, 0.47, and 0.43, respectively). Pretreatment IP-10 could not predict either fibrosis or response to PEG-IFN/RIB therapy in chronic HCV Egyptian patients.

Chronic inflammation, oxidative stress, and DNA damage are observed in schistosomiasis and premature aging. However, the potential of these events to trigger stress-induced premature senescence (SIPS) throughout schistosomiasis progression remains overlooked, especially in response to the first-line pharmacological treatment. Thus, we investigated the relationship between oxidative stress and SIPS sentinel markers in untreated Schistosoma mansoni-infected mice and those receiving praziquantel (Pz)-based reference treatment.

Background & Aims: Metabolic dysfunction-associated steatotic liver (MASLD) progression is driven by chronic inflammation and fibrosis, largely influenced by Kupffer cell (KC) dynamics, particularly replenishment of pro-inflammatory monocyte-derived KCs (MoKCs) due to increased death of embryo-derived KCs. Adenosine A3 receptor (A3AR) plays a key role in regulating metabolism and immune responses, making it a promising therapeutic target. This study aimed to investigate the impact of selective A3AR antagonism for regulation of replenished MoKCs, thereby improving MASLD.

Background: A comprehensive understanding of the molecular pathogenesis of chronic pancreatitis (CP), a fibroinflammatory disorder of the pancreas, is warranted for the development of targeted therapies. The current study focused on comparing the transcriptomes of pancreatic tissues obtained from patients with CP with those of two rodent models of chemically induced CP to identify dysregulated genes/signaling pathways.
Methods: Pancreatitis was induced in mice using cerulein and L-arginine.

Background: Hypertrophic scar (HS) is a fibroproliferative disorder resulting from abnormal healing of skin tissue after injury. Although various therapies are currently employed in clinical to treat HSs, there is no widely accepted standard therapy. Micro-plasma radiofrequency (MPR) and autologous chyle fat grafting are emerging treatments for this condition, and they have demonstrated promising therapeutic outcomes in clinical applications.

Background: The emerging incidence of pathogenic liver conditions is turning into a major concern for global health. Induction of pyroptosis in hepatocytes instigates cellular disintegration, which in turn liberates substantial quantities of pro-inflammatory intracellular substances, thereby accelerating the advancement of liver fibrosis. Consequently, directing therapeutic efforts towards inhibiting pyroptosis could potentially serve as an innovative approach in managing inflammation related chronic hepatic disorders.
