Helicobacter pylori (H. pylori) infection is highly associated with the occurrence of gastrointestinal diseases, including gastric inflammation, peptic ulcer, gastric cancer, and gastric mucosa-associated lymphoid-tissue lymphoma. Although alternative therapies, including phytomedicines and probiotics, have been used to improve eradication, current treatment still relies on a combination of antimicrobial agents, such as amoxicillin, clarithromycin, metronidazole, and levofloxacin, and antisecretory agents, such as proton pump inhibitors (PPIs). A standard triple therapy consisting of a PPI and two antibiotics (clarithromycin and amoxicillin/metronidazole) is widely used as the first-line regimen for treatment of infection, but the increased resistance of H. pylori to clarithromycin and metronidazole has significantly reduced the eradication rate using this therapy and bismuth-containing therapy or 10-d sequential therapy has therefore been proposed to replace standard triple therapy. Alternatively, levofloxacin-based triple therapy can be used as rescue therapy for H. pylori infection after failure of first-line therapy. The increase in resistance to antibiotics, including levofloxacin, may limit the applicability of such regimens. However, since resistance of H. pylori to amoxicillin is generally low, an optimized high dose dual therapy consisting of a PPI and amoxicillin can be an effective first-line or rescue therapy. In addition, the concomitant use of alternative medicine has the potential to provide additive or synergistic effects against H. pylori infection, though its efficacy needs to be verified in clinical studies.

Lipopolysaccharides (LPS) through Toll-like receptor 2 (TLR2) and Toll-like receptor 4 (TLR4) activation induce systemic inflammation where oxidative damage plays a key role in multiple organ failure. Because of the neutralization of LPS toxicity by sialic acid (SA), we determined its effect and mechanisms on repurified LPS (rLPS)-evoked acute renal failure. We assessed the effect of intravenous SA (10 mg/kg body weight) on rLPS-induced renal injury in female Wistar rats by evaluating blood and kidney reactive oxygen species (ROS) responses, renal and systemic hemodynamics, renal function, histopathology, and molecular mechanisms. SA can interact with rLPS through a high binding affinity. rLPS dose- and time-dependently reduced arterial blood pressure, renal microcirculation and blood flow, and increased vascular resistance in the rats. rLPS enhanced monocyte/macrophage (ED-1) infiltration and ROS production and impaired kidneys by triggering p-IRE1α/p-JNK/CHOP/GRP78/ATF4-mediated endoplasmic reticulum (ER) stress, Bax/PARP-mediated apoptosis, Beclin-1/Atg5-Atg12/LC3-II-mediated autophagy, and caspase 1/IL-1β-mediated pyroptosis in the kidneys. SA treatment at 30 min, but not 60 min after rLPS stimulation, gp91 siRNA and protein kinase C-α (PKC) inhibitor efficiently rescued rLPS-induced acute renal failure via inhibition of TLR4/PKC/NADPH oxidase gp91-mediated ER stress, apoptosis, autophagy and pyroptosis in renal proximal tubular cells, and rat kidneys. In response to rLPS or IFNγ, the enhanced Atg5, FADD, LC3-II, and PARP expression can be inhibited by Atg5 siRNA. Albumin (10 mg/kg body weight) did not rescue rLPS-induced injury. In conclusion, early treatment (within 30 min) of SA attenuates rLPS-induced renal failure via the reduction in LPS toxicity and subsequently inhibiting rLPS-activated TLR4/PKC/gp91/ER stress/apoptosis/autophagy/pyroptosis signaling.

Learning Objectives: After completing this course, the reader will be able to: List the top 10 ranked symptoms after discharge suffered by patients with hepatocellular carcinoma (HCC) receiving transarterial chemoembolization (TACE) treatment.Identify the significant factors in the associations between quality of life (QOL) and demographic factors and clinical factors over a period of 2 months in patients with HCC receiving TACE.Design individualized education programs for newly diagnosed and recurrent HCC patients in order to maintain better QOL after treatment.CME This article is available for continuing medical education credit at CME.TheOncologist.comObjective.: To (a) explore changes in physical and psychological distress and quality of life (QOL) and (b) identify the significant pre- and postdischarge factors related to changes in physical and mental domains of QOL over a period of 2 months in patients with hepatocellular carcinoma receiving one course of transarterial chemoembolization (TACE) treatment.Methods.: A longitudinal prospective design was used, with participants recruited from a teaching hospital in Northern Taiwan. Data were collected three times: within 3 days prior to discharge (T0) and at the fourth (T1) and eighth (T2) weeks after discharge. A set of structured questionnaires was used to assess participants' QOL, symptom distress, anxiety, and depression. Changes in QOL and associated factors were examined using generalized estimating equations.Results.: Eighty-nine patients were included in this study. Fatigue was reported to be the most distressful symptom after treatment. Overall QOL improved monthly after discharge. Change in physical QOL 2 months after TACE treatment was associated with age, diagnosis status, level of symptom distress, and depression after discharge. Change in mental QOL was significantly associated with gender, diagnosis status, and anxiety and depression after discharge.Conclusions.: Health care providers should pay special attention to patients of older age, those who are male, and those who have higher levels of depression and anxiety after discharge. Designing personalized education programs before discharge for patients with newly diagnosed cancer versus those who have recurrent disease is suggested to help patients maintain a better QOL after discharge.
