Animal Models and Helicobacter pylori Infection
Helicobacter pylori colonize the gastric mucosa of at least half of the world’s population. Persistent infection is associated with the development of gastritis, peptic ulcer disease, and an increased risk of gastric cancer and gastric-mucosa-associated lymphoid tissue (MALT) lymphoma.

Anti-HBV/HCV Therapy as Secondary Hepatocellular Carcinoma Prevention
Chronic infections with either hepatitis B or C virus (HBV or HCV) are among the most common risk factors for developing hepatocellular carcinoma (HCC). The hepatocarcinogenic potential of these viruses is mediated through a wide range of mechanisms, including the induction of chronic inflammation and oxidative stress and the deregulation of cellular pathways by viral proteins. Given the tumorigenic potential of HBV/HCV, it is no surprise that obtaining sustained viral suppression or eradication proves to be effective in preventing HCC.

Anti-inflammatory Effect of Rosmarinus Officinalis in Vivo Models
Rosemary was more commonly used in its entirety than in compounds, and the prevalent methods of extraction were maceration and hydrodistillation. Rosmarinus officinalis L. showed anti-inflammatory activity before and after induction of treatments.

Anti-SARS-CoV-2 Vaccines in Patients with Cirrhosis
Liver cirrhosis is followed by a profound immune dysfunction characterized by alterations in innate (decreased complement activity, reduced chemotaxis, and phagocytosis) and adaptive immunity (decreased memory cells, CD4 helper cells, T cell exhaustion) which leads to an inadequate immune response against a wide range of pathogens. The pathogenesis of what is known as ‘cirrhosis-associated immune dysfunction’ resides mainly in impairment of the hepatic reticulo-endothelial system, defective protein production, blood cell dysfunction, and systemic inflammation that is related to hepatocyte destruction.

Anti-TNFs in Pediatric Inflammatory Bowel Disease
Inflammatory bowel disease (IBD) is a chronic immune-mediated condition that affects the gastrointestinal tract. The incidence of the disease in children is increasing. However, most clinical trials in this disease have been carried out in adults, and the results have been extrapolated with minimal changes to determine treatment in children. Pediatric IBD (pIBD) is characterized by various factors, including a more severe phenotype than adult diseas. Since IBD is a chronic autoimmune disease, patients diagnosed during childhood live longer with the illness and consequently need treatment for longer. Biological drugs and, more specifically, anti-TNF drugs such as infliximab and adalimumab have proven efficient for treatment of IBD in adults and in children. However, the use of biological drugs differs between children and adults with IBD. For instance, the time between diagnosis and initiation of biological treatment is shorter in children than in adults. In addition, not all the biological drugs approved for adult IBD are approved for children.

Antibacterial and Antiviral Properties of Tetrahydrocurcumin-Based Formulations
Special attention was given to the bactericidal effects of one of the tetrahydrocurcumin (THC)-phospholipid formulations, which has shown greater bioavailability and activity than pure THC. Similarly, quinoline derivatives and amino acid conjugates of THC have also shown antibacterial effects in the gut. Furthermore, the antiviral characteristics of curcumin (Cur) compared to those of THC are more pronounced in preventing the influenza virus.

Antibiotic Resistance in Helicobacter pylori
Despite the declining trend of Helicobacter pylori (H. pylori) prevalence around the globe, ongoing efforts are still needed to optimize current and future regimens in view of the increasing antibiotic resistance. The resistance of H. pylori to different antibiotics is caused by different molecular mechanisms, and advancements in sequencing technology have come a far way in broadening our understanding and in facilitating the testing of antibiotic susceptibility to H. pylori.

Antibiotic Therapy for Active Crohn’s Disease Targeting Pathogens
Crohn’s disease (CD) is a multifactorial chronic disorder that involves a combination of factors, including genetics, immune response, and gut microbiota. Therapy includes salicylates, immunosuppressive agents, corticosteroids, and biologic drugs.

Antibiotics Related to Nonalcoholic Fatty Liver Disease
Nonalcoholic fatty liver disease, recently re-named metabolic dysfunction-associated steatotic fatty liver disease, is considered the most prevalent liver disease worldwide. Its molecular initiation events are multiple and not always well-defined, comprising insulin resistance, chronic low-grade inflammation, gut dysbiosis, and mitochondrial dysfunction, all of them acting on genetic and epigenetic grounds.

Antimicrobial Resistance in Escherichia coli
Public healthcare systems all over the world are faced with a great challenge in this respect. Obviously, there are many bacteria that can cause infections in humans and animals alike, but somehow it seems that the greatest threat nowadays comes from the Enterobacteriaceae members, especially Escherichia coli.
