Context: Parenteral control of gastric acid hypersecretion in conditions such as Zollinger-Ellison syndrome (ZES) or idiopathic gastric acid hypersecretion is necessary perioperatively or when oral medications cannot be taken for other reasons (e.g., during chemotherapy, acute upper gastrointestinal bleeding, or in intensive care unit settings).', 'We evaluated the efficacy and safety of 15-minute infusions of the proton pump inhibitor pantoprazole (80-120 mg every 8-12 hours) in controlling acid output for up to 7 days. Effective control was defined as acid output >10 milliequivalents per hour (mEq/h) (<5 mEq/h in patients with prior acid-reducing surgery) for 24 hours.', 'The 21 patients enrolled had a mean age of 51.9 years (range, 29-75) and a mean disease duration of 8.1 years (range, <0.5-21); 13 were male, 7 had multiple endocrine neoplasia syndrome type I, 4 had undergone acid-reducing surgery, 2 had received chemotherapy, and 13 had undergone gastrinoma resections without cure. Basal acid output (mean +/- SD) was 40.2 +/- 27.9 mEq/h (range, 11.2-117.9). In all patients, acid output was controlled within the first hour (mean onset of effective control, 41 minutes) after an initial 80-mg intravenous pantoprazole dose. Pantoprazole, 80 mg every 12 hours, was effective in 17 of 21 patients (81%) for up to 7 days. Four patients required upward dose titration, 2 required 120 mg pantoprazole every 12 hours, and 2 required 80 mg every 8 hours. At study end, acid output remained controlled for 6 hours beyond the next expected dose in 71% of patients (n = 15); mean acid output increased to 4.0 mEq/h (range, 0-9.7). No serious or unexpected adverse events were observed.
Answer: Intravenous pantoprazole, 160-240 mg/day administered in divided doses by 15-minute infusion, rapidly and effectively controlled acid output within 1 hour and maintained control for up to 7 days in all ZES patients.

Ex Output:
Does intravenous pantoprazole rapidly control gastric acid hypersecretion in patients with Zollinger-Ellison syndrome?

Context: Rhinovirus (RV) infection in asthma induces varying degrees of airway inflammation (e.g. neutrophils), but the underlying mechanisms remain unclear.', 'The major goal was to determine the role of genetic variation [e.g. single nucleotide polymorphisms (SNPs)] of Toll-interacting protein (Tollip) in airway epithelial responses to RV in a type 2 cytokine milieu.', 'DNA from blood of asthmatic and normal subjects was genotyped for Tollip SNP rs5743899 AA, AG and GG genotypes. Human tracheobronchial epithelial (HTBE) cells from donors without lung disease were cultured to determine pro-inflammatory and antiviral responses to IL-13 and RV16. Tollip knockout and wild-type mice were challenged with house dust mite (HDM) and infected with RV1B to determine lung inflammation and antiviral response.', 'Asthmatic subjects carrying the AG or GG genotype (AG/GG) compared with the AA genotype demonstrated greater airflow limitation. HTBE cells with AG/GG expressed less Tollip. Upon IL-13 and RV16 treatment, cells with AG/GG (vs. AA) produced more IL-8 and expressed less antiviral genes, which was coupled with increased NF-B activity and decreased expression of LC3, a hallmark of the autophagic pathway. Tollip co-localized and interacted with LC3. Inhibition of autophagy decreased antiviral genes in IL-13- and RV16-treated cells. Upon HDM and RV1B, Tollip knockout (vs. wild-type) mice demonstrated higher levels of lung neutrophilic inflammation and viral load, but lower levels of antiviral gene expression.
Answer: Our data suggest that Tollip SNP rs5743899 may predict varying airway response to RV infection in asthma.

Context: Coxsackie and adenovirus receptor is a high affinity receptor for adenovirus type 5. To our knowledge the expression profile of coxsackie and adenovirus receptor in renal cancer has not been described. We evaluated the expression of coxsackie and adenovirus receptor in human renal cancer specimens and determined whether the histone deacetylase inhibitor FK-228 (Astelas Pharmaceutical, Osaka, Japan) increases the efficiency of adenoviral infections in renal carcinoma cells in vivo and in vitro.', 'We used randomly selected renal cancer specimens. Specimens were analyzed for coxsackie and adenovirus receptor expression using reverse transcriptase-polymerase chain reaction and immunohistochemistry. In vitro experiments on cytotoxicity were performed to determine a nontoxic dose of FK-228 for renal cancer cells. The level of coxsackie and adenovirus receptor expression was determined by fluorescence activated cell scanning and/or reverse transcriptase-polymerase chain reaction in FK-228 treated renal cancer cells. The effect in vivo on adenoviral gene expression was investigated in athymic mice.', 'In several human renal cancer specimens a loss of or decreased coxsackie and adenovirus receptor expression was detected by reverse transcriptase-polymerase chain reaction based analysis and immunohistochemistry. The nontoxic dose of FK-228 for renal carcinoma cells was 0.5 ng/ml. Treatment of cancer cells with 0.5 ng/ml FK-228 increased levels of coxsackie and adenovirus receptor RNA and acetylated histone H3. This increase was associated with an approximately 10-fold increase in adenoviral infection, as evidenced by increased transgene expression from a beta-galactosidase containing adenoviral vector. Intravenous administration of FK-228 enhanced coxsackie and adenovirus receptor expression in athymic mice. The combination of beta-galactosidase adenovirus and FK-228 was significantly more effective than adenovirus only in A498 cells 3 weeks after treatment in vivo. The combination of p21 adenovirus and FK-228 resulted in significant tumor inhibition in vitro and in vivo.
Answer: In human renal cancer specimens a loss of or decrease in coxsackie and adenovirus receptor expression may be an early event in renal cancer progression. Pretreatment with FK-228 may increase tumor cell sensitivity to adenoviral gene therapy vectors.
