Clinical journal of gastroenterology. 2019;(6):588-591
Abstract
Glecaprevir (GLE)/pibrentasvir (PIB) is a direct-acting antiviral regimen approved for patients infected with hepatitis C virus. No data are available on the safety and efficacy of this regimen when crushed and administered through a percutaneous endoscopic gastrostomy (PEG) tube. Here, we report a patient who successfully achieved a sustained viral response after treatment with GLE/PIB administered via a PEG tube. A 41-year-old female with chronic hepatitis C viral infection was referred to our department for treatment. She had a history of spina bifida and hydrocephalus, and she received a PEG tube for nutrition and medication due to an aftereffect of hydrocephalus. She received crushed GLE/PIB treatment through a PEG tube for 8 weeks and achieved a sustained viral response 12, without any treatment-related severe adverse events. This is the first documented case treated with GLE/PIB administered through a PEG tube. Based on this case report and a review of the literature, we discuss the safety and efficacy of direct-acting antiviral treatment via a PEG tube.

Abstract
PURPOSE The aim of this study was to evaluate the blood pressure-lowering and cholesterol-lowering effects of a fixed-dose combination therapy using candesartan (CND)/rosuvastatin (RSV) compared with CND or RSV monotherapy in patients with hypertension and hypercholesterolemia. METHODS This study was a 12-week, randomized, double-blind, placebo-controlled, multicenter study. A total of 394 patients were screened. After a 4-week run-in period, 219 of these patients with hypertension and primary hypercholesterolemia were randomized. Patients received 1 of 3 regimens for 8 weeks: (1) CND 32 mg/RSV 20 mg, (2) RSV 20 mg, or (3) CND 32 mg. The primary outcome variables were changes in the systolic blood pressure (SBP) and diastolic blood pressure (DBP) and the percentage changes in LDL-C from baseline to the drug treatment at 8 weeks. The secondary outcome variables were percentage changes of total cholesterol, triglycerides, HDL-C, non-HDL-C, apolipoprotein B, apolipoprotein A-I, high-sensitivity C-reactive protein, and glucose metabolic indices, including percentage changes of the homeostasis model assessment of insulin resistance (HOMA-IR), adiponectin, and hemoglobin A1c. Tolerability of combination therapy was compared with other monotherapy groups. FINDINGS The percentage changes of LDL-C were -48.6% (from 157.2 to 80.1 mg/dL) in the RSV group and -49.8% (from 160.2 to 78.9 mg/dL) in the CND/RSV group from baseline to the end of 8 weeks of treatment. Mean SBP and DBP were significantly decreased in the CND/RSV and CND groups after 8 weeks (P < 0.001 for all); however, no significant differences were found between the 2 groups. Total cholesterol levels, triglycerides, non-HDL-C, and apolipoprotein B were significantly reduced in the CND/RSV and RSV groups, with no significant differences between the groups compared with the CND group (P < 0.001 for all). The percentage changes of HOMA-IR, adiponectin, and hemoglobin A1c had no significant differences between the combination groups and monotherapy groups. However, in a 2-sample t test, HOMA-IR was significantly decreased in the CND/RSV group compared with the RSV group in nondiabetic patients (mean [SD] percentage change of HOMA-IR, -8.7% [37.6%] vs 17.1% [53.1%]; P = 0.048). There were no significant differences in metabolic indices between the diabetic groups. Adverse events in the CND/RSV group were similar to those in the monotherapy group. IMPLICATIONS Once-daily fixed-dose combination therapy with CND/RSV is an effective, tolerable, convenient treatment option for patients with essential hypertension and hypercholesteremia.

Xiong, X, Song, L, Chen, F, Ma, X
Archives of dermatological research. 2019;(10):801-805
Abstract
The present study aimed to observe the therapeutic effect of combined mizolastine and proteoglycan in chronic urticaria. The patients were randomly divided into the treatment group (n = 56) and the control group (n = 44). The treatment group was medicated with calcium gluconate (10 mg/ time, 1 time/day), vitamin D3 (intramuscular 10 mg/time, 1 time/week), mizolastine (10 mg/time, 1 time/day), and proteoglycan (1.2 g/time, 3 times/day), while the control group was administered with the same drugs except proteoglycan for 4 weeks. After treatment with combined mizolastine and proteoglycan, therapeutic effect with symptoms decline index (SDI) more than 60% was significant different (44 vs. 24, p = 0.000973) and the relapse rate after 2 months was significantly lower (17.9% vs. 38.6%, p = 0.0202). Using ELISA, we found that the IFN-γ (37.88 ± 4.27 pg/mL vs. 21.91 ± 4.95 pg/mL, p = 0.028) levels were specifically increased in the experiment group. The combination of mizolastine plus proteoglycan is effective in treating chronic urticaria with better therapeutic effect and lower relapse rate through promoting IFN-γ production.

Lomitapide and Mipomersen-Inhibiting Microsomal Triglyceride Transfer Protein (MTP) and apoB100 Synthesis.
Blom, DJ, Raal, FJ, Santos, RD, Marais, AD
Current atherosclerosis reports. 2019;(12):48
Abstract
PURPOSE OF REVIEW The goal of this review is to evaluate the role of inhibiting the synthesis of lipoproteins when there is no or little residual LDL-receptor function as in patients with homozygous familial hypercholesterolaemia. Lomitapide is administered orally once a day while mipomersen is given by subcutaneous injection once a week. Lomitapide inhibits microsomal triglyceride transfer protein while mipomersen is an antisense oligonucleotide directed against apoB100. RECENT FINDINGS The pivotal registration trials for lomitapide and mipomersen were published in 2013 and 2010, respectively. More recently published data from extension trials and cohort studies provides additional information on long-term safety and efficacy. The mean LDL cholesterol reduction was 50% with lomitapide in its single-arm open-label registration trial. Mipomersen reduced LDL cholesterol by approximately 25% in its double-blind, placebo-controlled registration study. Both lomitapide and mipomersen therapy are associated with variable increases in hepatic fat content. The long-term safety of increased hepatic fat content in patients receiving these therapies is uncertain and requires further study. Both drugs may cause elevated transaminase in some patients, but no cases of severe liver injury have been reported. Lomitapide may also cause gastrointestinal discomfort and diarrhoea, especially if patients consume high-fat meals and patients are advised to follow a low-fat diet supplemented with essential fatty acids and fat-soluble vitamins. Mipomersen may cause injection-site and influenza-like reactions. The effect of lomitapide and mipomersen on cardiovascular outcomes has not been studied, but circumstantial evidence suggests that the LDL cholesterol lowering achieved with these two agents may reduce cardiovascular event rates.

Palumbo, A, Lau, G, Saraceni, M
The Annals of pharmacotherapy. 2019;(2):178-185
Abstract
OBJECTIVE To review the pharmacology, efficacy, and safety of the cyclin-dependent kinase (CDK) inhibitor, abemaciclib, in the treatment of advanced or metastatic breast cancer (MBC). DATA SOURCES Relevant information was identified through a MEDLINE/PubMed (January 2000 to June 2018) literature search. The new drug application, prescribing information, and abstracts and posters from scientific meetings were also reviewed. STUDY SELECTION/DATA EXTRACTION The literature search was limited to human studies published in the English language. Phase 1, 2, and 3 studies evaluating the pharmacology, efficacy, or safety of abemaciclib for breast cancer were included. DATA SYNTHESIS Abemaciclib is an oral, potent, small molecule inhibitor of CDK4 and CDK6 activity, which blocks retinoblastoma tumor suppressor protein phosphorylation and thereby prevents progression through the cell cycle. Three major clinical trials, MONARCH 1, 2, and 3, established the efficacy and safety of abemaciclib for the treatment of hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or MBC. In these trials, response rates were promising, ranging from 19.7% to 59%, and median progression-free survival was significantly prolonged over the control arm in 2 of the trials. Common adverse effects included diarrhea, neutropenia, nausea, abdominal pain, infections, and fatigue. Relevance to Patient Care and Clinical Practice: Although no head-to-head studies have been completed between the CDK4/6 inhibitors, abemaciclib may be an attractive option because of its continuous dosing and ability to be used as monotherapy. CONCLUSIONS Abemaciclib is an effective and well-tolerated treatment for HR-positive, HER2-negative advanced or metastatic breast cancer.

Abstract
OBJECTIVE To assess whether long-term treatment with candesartan/hydrochlorothiazide, rosuvastatin, or their combination can slow cognitive decline in older people at intermediate cardiovascular risk. METHODS The Heart Outcomes Prevention Evaluation-3 (HOPE-3) study was a double-blind, randomized, placebo-controlled clinical trial using a 2 × 2 factorial design. Participants without known cardiovascular disease or need for treatment were randomized to candesartan (16 mg) plus hydrochlorothiazide (12.5 mg) or placebo and to rosuvastatin (10 mg) or placebo. Participants who were ≥70 years of age completed the Digit Symbol Substitution Test (DSST), the modified Montreal Cognitive Assessment, and the Trail Making Test Part B at baseline and study end. RESULTS Cognitive assessments were completed by 2,361 participants from 228 centers in 21 countries. Compared with placebo, candesartan/hydrochlorothiazide reduced systolic blood pressure by 6.0 mm Hg, and rosuvastatin reduced low-density lipoprotein cholesterol by 24.8 mg/dL. Participants were followed up for 5.7 years (median), and 1,626 completed both baseline and study-end assessments. Mean participant age was 74 years (SD ±3.5 years); 59% were women; 45% had hypertension; and 24% had ≥12 years of education. The mean difference in change in DSST scores was -0.91 (95% confidence interval [CI] -2.25 to 0.42) for candesartan/hydrochlorothiazide compared with placebo, -0.54 (95% CI -1.88 to 0.80) for rosuvastatin compared with placebo, and -1.43 (95% CI -3.37 to 0.50) for combination therapy vs double placebo. No significant differences were found for other measures. CONCLUSIONS Long-term blood pressure lowering with candesartan plus hydrochlorothiazide, rosuvastatin, or their combination did not significantly affect cognitive decline in older people. CLINICALTRIALSGOV IDENTIFIER NCT00468923. CLASSIFICATION OF EVIDENCE This study provides Class II evidence that for older people, candesartan plus hydrochlorothiazide, rosuvastatin, or their combination does not significantly affect cognitive decline.

Abstract
UNLABELLED BACKGROUND AND OBJECTIVES The efficacy of < 12 weeks of hepatitis C virus (HCV) treatment in patients co-infected with HCV and human immunodeficiency virus type 1 (HIV-1) has not been established. We assessed the efficacy and safety of ledipasvir-sofosbuvir for 8 weeks in HCV mono-infected and HCV/HIV-1 co-infected patients. METHODS We enrolled patients mono-infected with genotype 1 HCV or co-infected with HCV and HIV-1 who were HCV treatment-naive and did not have cirrhosis. HCV/HIV-1 co-infected patients were either not receiving antiretroviral treatment and had a CD4 T-cell count > 500 cells/mm3 or were receiving a protocol-approved antiretroviral regimen for ≥ 8 weeks (or ≥ 6 months for abacavir-containing regimens) and had HIV-1 RNA < 50 copies/mL and a CD4 T-cell count > 200 cells/mm3. Patients received ledipasvir-sofosbuvir (90/400 mg) once daily for 8 weeks. The primary efficacy endpoint was sustained virologic response 12 weeks after treatment discontinuation (SVR12). RESULTS The SVR12 rate was 100% (67/67) for HCV mono-infected patients and 97% (57/59) for HCV/HIV-1 co-infected patients. Two patients relapsed by the week 4 post-treatment visit. Overall, the most common adverse events were headache (52%) and upper abdominal pain (26%). There were no serious adverse events or treatment discontinuations due to adverse events. No HCV/HIV-1 co-infected patients receiving antiretroviral treatment experienced HIV virologic rebound, and no clinically meaningful changes in CD4 T-cell counts were observed in any co-infected patient. CONCLUSIONS Non-cirrhotic, treatment-naive patients with genotype 1 HCV mono-infection and HCV/HIV-1 co-infection achieved high rates of SVR12 with 8 weeks of treatment with ledipasvir/sofosbuvir.

Abstract
BACKGROUND Currently, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists are indicated to slow gastrointestinal motility in the diarrhea-predominant subtype of irritable bowel syndrome. They are commonly used to prevent or treat postoperative nausea and vomiting (PONV) and opioid-induced nausea and vomiting (OINV). We conducted a prospective, randomized, double-blinded study to investigate whether the continuous administration of ramosetron, a selective 5-HT3 receptor antagonist, for preventing PONV and/or OINV after laparoscopic distal gastrectomy (LDG) might influence bowel function recovery. METHODS Patients scheduled to undergo LDG were randomly assigned to 1 of 3 treatment regimens: no prophylactic ramosetron (Group C); ramosetron 0.6 mg added to 2-day intravenous patient-controlled analgesia (IV-PCA) (Group R0.6); and ramosetron 1.2 mg added to 2-day IV-PCA (Group R1.2). Postoperative recovery profiles of bowel function, incidence of postoperative nausea/vomiting and pain, and perioperative data that affected bowel function recovery were evaluated. RESULTS Seventy-three patients completed the study protocol. Parameters associated with postoperative recovery of bowel function, such as time to first flatus, time to first bowel movement, time to first defecation, and time to commencement of soft diet, were not significantly different between the 3 groups. The incidence of nausea 2 to 24 hours after surgery was significantly lower in Group R0.6 (20.0%) and Group R1.2 (12.5%) than in Group C (45.8%) (P < .022). The ratio of complete response 2 to 24 hours after surgery was significantly higher in Group R0.6 (80.0%) and Group R1.2 (87.5%) than in Group C (54.2%) (P < .022). The incidence of retching 24 to 48 hours after surgery was significantly lower in Group R0.6 (0.0%) and Group R1.2 (4.2%) than in Group C (16.7%) (P < .043). CONCLUSION Continuous administration of ramosetron with patient-controlled analgesia to prevent PONV and OINV after LDG did not delay postoperative bowel function recovery.

Abstract
Over 2,200 patients infected with hepatitis C virus (HCV) genotypes (GT) 1 to 6, with or without cirrhosis, who were treatment naive or experienced to interferon, ribavirin, and/or sofosbuvir were treated with glecaprevir/pibrentasvir for 8, 12, or 16 weeks in eight registrational phase 2 and 3 clinical studies. High rates of sustained virologic response at 12 weeks postdosing (SVR12) were achieved with a <1% virologic failure (VF) rate. The prevalence of baseline polymorphisms (BPs) in NS3 at amino acid position 155 or 168 was low (<3%) in patients infected with GT1, GT2, GT3, GT4, and GT6, while 41.9% of the GT5-infected patients had NS3-D168E; BPs were not detected at position 156 in NS3. The prevalence of NS5A-BPs was high across genotypes, driven by common polymorphisms at amino acid position 30 or 31 in GT2, 58 in GT4, and 28 in GT6. The prevalence of NS5A T/Y93 polymorphisms was 5.5% in GT1, 4.9% in GT3, and 12.5% in GT6. Consistent with the activity of glecaprevir and pibrentasvir against most amino acid polymorphisms in vitro, BPs in NS3 and/or NS5A did not have an impact on treatment outcome for patients infected with GT1 to GT6, with the exception of treatment-experienced GT3-infected patients treated for 12 weeks, for whom a 16-week regimen of glecaprevir/pibrentasvir was required to achieve SVR12 rates of ≥95%. Among the 22 patients experiencing VF, treatment-emergent substitutions were detected in NS3 in 50% of patients and in NS5A in 82% of patients, frequently as a combination of substitutions that conferred resistance to glecaprevir and/or pibrentasvir. The glecaprevir/pibrentasvir regimen, when the recommended durations are used, allows for a pan-genotypic treatment option without the need for baseline resistance testing.

Abstract
BACKGROUND It is unclear whether modifying cholesterol, blood pressure, or both affect erectile dysfunction. Also, there are concerns that erectile dysfunction is worsened by common medications used to treat these risk factors. In this study, we evaluated the effect of: (1) cholesterol-lowering with a statin; (2) pharmacologic blood pressure reduction; and (3) their combination, on erectile function. METHODS A priori, this was a secondary analysis of the Heart Outcomes Prevention Evaluation-3 (HOPE-3) randomized controlled trial. Men were 55 years of age or older with at least 1 cardiovascular risk factor. Erectile function was measured using the erectile function domain of the International Index of Erectile Function (IIEF-EF) score. Men with incomplete scores, or who did not engage in sexual activity, were excluded. Using a 2 × 2 factorial design, participants were randomized to rosuvastatin (10 mg/d) or placebo, and to candesartan with hydrochlorothiazide (HCTZ; 16 mg/12.5 mg/d; Cand+HCTZ) or placebo. Primary outcome was change in IIEF-EF from baseline to end of study follow-up. RESULTS Two thousand one hundred fifty-three men were included; mean age was 61.5 years, and mean follow-up was 5.8 years. Mean IIEF-EF score at baseline was 23.0 (SD 5.6). Least square mean change in the IIEF-EF score did not differ with rosuvastatin compared with placebo (-1.4; standard error [SE], 0.3 vs -1.5; SE, 0.3; P = 0.74), Cand+HCTZ compared with placebo (-1.6; SE, 0.3 vs -1.3; SE, 0.3; P = 0.10), or combination therapy compared with double placebo (P = 0.35). CONCLUSIONS Cholesterol-lowering using a statin, and blood pressure-lowering using Cand+HCTZ, either alone or in combination, do not improve or adversely affect erectile function.
