Prediction of hepatocellular carcinoma using age and liver stiffness on transient elastography after hepatitis C virus eradication.

Liver stiffness measurement (LSM) is a useful tool for assessing advanced liver fibrosis, an important risk factor for hepatocellular carcinoma (HCC) following hepatitis C (HCV) eradication. This study aimed to clarify the non-invasive factors associated with HCC following sustained virological response (SVR) and to identify the low-risk group. 567 patients without history of HCC who achieved SVR at 24 weeks (SVR24) after IFN-free treatment were retrospectively analyzed. The cumulative incidence of HCC and the risk factors were examined using pre-treatment and SVR24 data. The median observation period was 50.2 months. Thirty cases of HCC were observed, and the 4-year cumulative incidence of HCC was 5.9%. In multivariate analysis, significant pre-treatment factors were age ≥ 71 years (hazard ratio [HR]: 3.402) and LSM ≥ 9.2 kPa (HR: 6.328); SVR24 factors were age ≥ 71 years (HR: 2.689) and LSM ≥ 8.4 kPa (HR: 6.642). In cases with age < 71 years and LSM < 8.4 kPa at the time of SVR24, the 4-year cumulative incidence of HCC was as low as 1.1%. Both pre-treatment LSM (≥ 9.2 kPa) and SVR24 LSM (≥ 8.4 kPa) and age (≥ 71 years) are useful in predicting the risk of HCC after SVR with IFN-free treatment. Identification of low-risk individuals may improve the efficiency of follow-up.

A randomized clinical trial of the efficacy and safety of sitagliptin as initial oral therapy in youth with type 2 diabetes.

OBJECTIVE: To assess the efficacy and safety of DPP-4 inhibition with sitagliptin in youth with type 2 diabetes (T2D). STUDY DESIGN: This was a 54-week, double-blind, randomized, controlled clinical trial evaluating the safety and efficacy of DPP-4 inhibition with sitagliptin 100 mg once daily as initial oral therapy in youth with T2D. The 190 participants, aged 10-17 years, had HbA1c 6.5%-10% (7.0%-10% if on insulin). All were negative for pancreatic autoantibodies and overweight/obese at screening or diagnosis. The trial was placebo controlled for the first 20 weeks, after which metformin replaced placebo. The primary efficacy endpoint was change from baseline in HbA1c at Week 20. RESULTS: Treatment groups were well balanced at baseline (mean ± SD HbA1c = 7.5% ± 1.0, BMI percentile = 97.1% ± 6.8, age = 14.0 years ± 2.0 [57.4% <15], 60.5% female). At Week 20, least squares mean changes from baseline in HbA1c were -0.01% (sitagliptin) and 0.18% (placebo); between-group difference (95% CI) = -0.19% (-0.68, 0.30), p = 0.448. At Week 54, the changes in HbA1c were 0.45% (sitagliptin) and -0.11 (placebo/metformin). There were no notable between-group differences in the adverse event profiles through Week 54. CONCLUSIONS: DPP-4 inhibition with sitagliptin did not provide significant improvement in glycemic control. In this study, sitagliptin was generally well tolerated with a safety profile similar to that reported in adults. (ClinicalTrials.gov: NCT01485614; EudraCT: 2011-002528-42).

Efficacy and safety of the addition of sitagliptin to treatment of youth with type 2 diabetes and inadequate glycemic control on metformin without or with insulin.

OBJECTIVE: To assess the efficacy and safety of sitagliptin in youth with type 2 diabetes (T2D) inadequately controlled with metformin ± insulin. STUDY DESIGN: Data were pooled from two 54-week, double-blind, randomized, placebo-controlled studies of sitagliptin 100 mg daily or placebo added onto treatment of 10- to 17-year-old youth with T2D and inadequate glycemic control on metformin ± insulin. Participants (N = 220 randomized and treated) had HbA1c 6.5%-10% (7.0%-10% if on insulin), were overweight/obese at screening or diagnosis and negative for pancreatic autoantibodies. The primary endpoint was change from baseline in HbA1c at Week 20. RESULTS: Treatment groups were well balanced at baseline (mean HbA1c = 8.0%, BMI = 30.9 kg/m2 , age = 14.4 years [44.5% <15], 65.9% female). The dose of background metformin was >1500 mg/day for 71.8% of participants; 15.0% of participants were on insulin therapy. At Week 20, LS mean changes from baseline (95% CI) in HbA1c for sitagliptin/metformin and placebo/metformin were -0.58% (-0.94, -0.22) and -0.09% (-0.43, 0.26), respectively; difference = -0.49% (-0.90, -0.09), p = 0.018; at Week 54 the LS mean (95% CI) changes were 0.35% (-0.48, 1.19) and 0.73% (-0.08, 1.54), respectively. No meaningful differences between the adverse event profiles of the treatment groups emerged through Week 54. CONCLUSIONS: These results do not suggest that addition of sitagliptin to metformin provides durable improvement in glycemic control in youth with T2D. In this study, sitagliptin was generally well tolerated with a safety profile similar to that reported in adults. (ClinicalTrials.gov: NCT01472367, NCT01760447; EudraCT: 2011-002529-23/2014-003583-20, 2012-004035-23).

Consumption of single products versus fixed-dose combination medicines for hypertension and hyperlipidemia during 2015-2019 in South Korea.

BACKGROUND: Fixed-dose combinations can simplify prescribing, and numerous combination products exist for hypertension and dyslipidemia in South Korea. This study's aim was to compare trends in the consumption of single products versus fixed-dose combinations for hypertension and hyperlipidemia. METHODS AND FINDINGS: We analyzed the Korean national health insurance claims database from January 2015 through December 2019. Consumption of medicines was calculated using the defined daily dose per 1,000 inhabitants per day (DIDs) and expenditures over time. During 2015-2019, the use of antihypertensive drugs increased with an annual growth rate (AGR) of 0.9% for single products and with an AGR of 35.6% for fixed-dose combinations. A notable increase was observed for antihyperlipidemic combination drugs with an AGR of 268.1% compared to single products with 35.7%. For older adults (65+ years), the consumption of drugs for hypertension and hyperlipidemia was 3-4.5 and about 3 times higher, respectively, than in adults aged 20-64 years, and a sharp increase was found in antihyperlipidemic fixed-dose combinations among older adults. A large increase was seen for C09 (agents acting on the renin-angiotensin system) with an AGR of 36.5%, especially C09DB (angiotensin II receptor blockers + calcium channel blockers) was widely used and steeply increased with 114.2%. For antihyperlipidemic drugs, C10AA (HMG CoA reductase inhibitors) accounted for a large share and sharply increased, with 52.1 DIDs in 2019 and with an AGR of 78.4%, whereas C10BA (combinations of various lipid modifying agents) increased 9.6 times from 2.9 DIDs (96 million USD) in 2015 to 27.7 DIDs (912 million USD) in 2019. CONCLUSION: The findings of increased consumption and drug spending among older adults underscores the need for real-world evidence about health outcomes of fixed-dose combinations in this population.

Thoracic stereotactic body radiation therapy plus first-line tyrosine kinase inhibitors for patients with epidermal growth factor receptor-mutant polymetastatic non-small-cell lung cancer: A propensity-matched retrospective study.

ABSTRACT: The role of thoracic stereotactic body radiation therapy (SBRT) in addition to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) in EGFR-mutant polymetastatic non-small-cell lung cancer (NSCLC) has not been well established. This retrospective study aimed to evaluate the efficacy and safety of EGFR-TKIs with thoracic SBRT for the treatment of this patient group.Polymetastatic NSCLC was defined as having >5 metastatic lesions. Patients with polymetastatic NSCLC harboring positive EGFR mutations after initial TKI therapy for at least 8 weeks were eligible for SBRT between August 2016and August 2019. Eligible patients were treated with thoracic SBRT, and TKIs were administered for the duration of SBRT and continued after SBRT until they were considered ineffective. The control group was treated with TKI monotherapy. Propensity score matching (ratio of 1:4) was used to account for differences in baseline characteristics. Progression-free survival (PFS), overall survival, and treatment safety were evaluated.In total, 136 patients were included in the study population. Among them, 120 patients received TKIs alone, and 16 patients received TKIs with thoracic SBRT. The baseline characteristics did not significantly differ between the two cohorts after propensity score matching. The median PFS was 17.8 months in the thoracic SBRT group and 10.8 months in the control group (P = .033). In the multivariate analysis, a Cox regression model showed that thoracic SBRT was an independent statistically significant positive predictor of improved survival, with a hazard ratio of 0.54 (P = .046). We recorded no severe toxic effects or grade 4 to 5 toxicities.Real-world data demonstrate that thoracic SBRT significantly extends PFS in EGFR-mutant polymetastatic NSCLC patients with tolerable toxicity. Given these results, randomized studies are warranted.

Efficacy of Combination Therapy with Apigenin and Synovial Membrane-Derived Mesenchymal Stem Cells on Knee Joint Osteoarthritis in a Rat Model.

Background: Osteoarthritis (OA) is a degenerative joint disease that causes a variety of adverse health effects. Considering the need to identify additional effective therapeutic options for OA therapy, we investigated the effect of co-injection of apigenin and synovial membrane-derived mesenchymal stem cells (SMMSCs) on OA in male rats' knee joints. Methods: The study was performed in 2019 at the Department of Pharmacology, Shiraz University of Medical Sciences, Shiraz, Iran. Anterior cruciate ligament transection (ACLT) was used to induce OA. For three weeks, male Sprague-Dawley rats (eight groups, n=6 each) were treated once-weekly with intra-articular injections of apigenin alone or in combination with SMMSC (three million cells), phosphate-buffered saline, or hyaluronic acid. After three months, the interleukin 1 beta (IL-1ß), tumor necrosis factor-alpha (TNF-α), superoxide dismutase (SOD), and malondialdehyde (MDA) levels were measured in the cartilage homogenate. The expression of extracellular matrix (ECM) components including collagen 2a1, aggrecan, IL-1ß, TNF-α, inducible nitric oxide synthase (iNOS), transcription factor SOX-9, and matrix metalloproteinases 3 and 13 were assessed using real-time polymerase chain reaction (RT-PCR) analysis. Radiological evaluation and histopathological assessment were used to evaluate the knees. Results: Levels of TNF-α (P=0.009), MDA (P>0.001), and IL-1ß (P<0.001) decreased and the level of SOD increased (P=0.004) in the apigenin 0.3 µM with SMMSCs group. RT-PCR analysis indicated that IL-1ß in the apigenin 0.3 µM with SMMSCs group reduced significantly (P<0.001). This group also exhibited increased expression levels of SOX-9, collagen 2a1, and aggrecan (P<0.001). Conclusion: Apigenin may have supplementary beneficial effects on cell therapy in a rat model of OA due to its possible effect on the reduction of oxidative stress, suppression of inflammation, and promotion of production of ECM components.

Feasibility of therapeutic plasma exchange-based combination therapy in the treatment of acquired hemophilia A: A retrospective 6 case series.

ABSTRACT: Poor availability and a lack of affordability of bypassing agents (recombinant activated factor VII and activated prothrombin complex concentrate) in west China prompted us to investigate an alternative cost-effective combination therapy. We aimed to explore the feasibility of therapeutic plasma exchange (TPE)-based combination therapy in the treatment of acquired hemophilia A (AHA).We retrospectively investigated the clinical features of AHA in 6 patients who were treated with a combination of TPE, corticosteroids, and rituximab in our department for 9 years between January, 2011 and December, 2019.We examined 1 male and 5 female patients. The median age at diagnosis of AHA was 51 years (18-66 years). In all patients, FVIII activity levels were low (median: 1.5%; 1-3%), FVIII inhibitor titers were high (median: 24.5 BU/mL; 13.2-48.6 BU/mL), and activated partial thromboplastin time was markedly prolonged (median: 99.4 s; 60.9-110.1 s). They underwent 2 to 8 cycles of plasma exchange and were given varying combinations of dexamethasone, methylprednisolone, prednisone, and rituximab. After TPE bleeding gradually stopped, and activated partial thromboplastin time decreased. After 3 months of treatment, FVIII inhibitors completely disappeared.TPE when combined with corticosteroids and rituximab, as adjunctive immunosuppressive agents, may be an effective and reliable treatment for AHA. When there is no alternative, intensive first-line treatment including TPE may be lifesaving.

Impact of Optimal Medical Therapy on 10-Year Mortality After Coronary Revascularization.

BACKGROUND: The benefit of optimal medical therapy (OMT) on 5-year outcomes in patients with 3-vessel disease and/or left main disease after percutaneous coronary intervention or coronary artery bypass grafting (CABG) was demonstrated in the randomized SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) trial. OBJECTIVES: The objective of this analysis is to assess the impact of the status of OMT at 5 years on 10-year mortality after percutaneous coronary intervention or CABG. METHODS: This is a subanalysis of the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) study, which evaluated for up to 10 years the vital status of patients who were originally enrolled in the SYNTAX trial. OMT was defined as the combination of 4 types of medications: at least 1 antiplatelet drug, statin, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, and beta-blocker. After stratifying participants by the number of individual OMT agents at 5 years and randomized treatment, a landmark analysis was conducted to assess the association between treatment response and 10-year mortality. RESULTS: In 1,472 patients, patients on OMT at 5 years had a significantly lower mortality at 10 years compared with those on ≤2 types of medications (13.1% vs 19.9%; adjusted HR: 0.470; 95% CI: 0.292-0.757; P = 0.002) but had a mortality similar to those on 3 types of medications. Furthermore, patients undergoing CABG with the individual OMT agents, antiplatelet drug and statin, at 5 years had lower 10-year mortality than those without. CONCLUSIONS: In patients with 3-vessel and/or left main disease undergoing percutaneous coronary intervention or CABG, medication status at 5 years had a significant impact on 10-year mortality. Patients on OMT with guideline-recommended pharmacologic therapy at 5 years had a survival benefit.

Comparative Effectiveness of Sodium-Glucose Cotransporter 2 Inhibitors vs Sulfonylureas in Patients With Type 2 Diabetes.

Importance: In the treatment of type 2 diabetes, evidence of the comparative effectiveness of sodium-glucose cotransporter 2 (SGLT2) inhibitors vs sulfonylureas-the second most widely used antihyperglycemic class after metformin-is lacking. Objective: To evaluate the comparative effectiveness of SGLT2 inhibitors and sulfonylureas associated with the risk of all-cause mortality among patients with type 2 diabetes using metformin. Design, Setting, and Participants: A cohort study used data from the US Department of Veterans Affairs compared the use of SGLT2 inhibitors vs sulfonylureas in individuals receiving metformin for treatment of type 2 diabetes. A total of 23 870 individuals with new use of SGLT2 inhibitors and 104 423 individuals with new use of sulfonylureas were enrolled between October 1, 2016, and February 29, 2020, and followed up until January 31, 2021. Exposures: New use of SGLT2 inhibitors or sulfonylureas. Main Outcomes and Measures: This study examined the outcome of all-cause mortality. Predefined variables and covariates identified by a high-dimensional variable selection algorithm were used to build propensity scores. The overlap weighting method based on the propensity scores was used to estimate the intention-to-treat effect sizes of SGLT2 inhibitor compared with sulfonylurea therapy. The inverse probability of the treatment adherence weighting method was used to estimate the per-protocol effect sizes. Results: Among the 128 293 participants (mean [SD] age, 64.60 [9.84] years; 122 096 [95.17%] men), 23 870 received an SGLT2 inhibitor and 104 423 received a sulfonylurea. Compared with sulfonylureas, SGLT2 inhibitors were associated with reduced risk of all-cause mortality (hazard ratio [HR], 0.81; 95% CI, 0.75-0.87), yielding an event rate difference of -5.15 (95% CI, -7.16 to -3.02) deaths per 1000 person-years. Compared with sulfonylureas, SGLT2 inhibitors were associated with a reduced risk of death, regardless of cardiovascular disease status, in several categories of estimated glomerular filtration rate (including rates from >90 to ≤30 mL/min/1.73 m2) and in participants with no albuminuria (albumin to creatinine ratio [ACR] ≤30 mg/g), microalbuminuria (ACR >30 to ≤300 mg/g), and macroalbuminuria (ACR >300 mg/g). In per-protocol analyses, continued use of SGLT2 inhibitors was associated with a reduced risk of death compared with continued use of sulfonylureas (HR, 0.66; 95% CI, 0.60-0.74; event rate difference, -10.10; 95% CI, -12.97 to -7.24 deaths per 1000 person-years). In additional per-protocol analyses, continued use of SGLT2 inhibitors with metformin was associated with a reduced risk of death compared with SGLT2 inhibitor treatment without metformin (HR, 0.70; 95% CI, 0.50-0.97; event rate difference, -7.62; 95% CI, -17.12 to -0.48 deaths per 1000 person-years). Conclusions and Relevance: In this comparative effectiveness study analyzing data from the US Department of Veterans Affairs, among patients with type 2 diabetes receiving metformin therapy, SGLT2 inhibitor treatment was associated with a reduced risk of all-cause mortality compared with sulfonylureas. The results provide data from a real-world setting that might help guide the choice of antihyperglycemic therapy.

A Systematic Review of Complex Polypharmacy in Bipolar Disorder: Prevalence, Clinical Features, Adherence, and Preliminary Recommendations for Practitioners.

Objective: Extensive combination pharmacotherapy regimens for bipolar disorder have gained increasing use in routine practice in ways that outpace data from evidence-based clinical trials. The present review examined the prevalence of complex pharmacotherapy regimens in bipolar disorder patients and sought to characterize factors that most influence polypharmacy prescribing patterns.Data Sources: The authors independently systematically searched the MEDLINE, PsycINFO, and Embase databases for English-language observational/naturalistic or randomized controlled polypharmacy trials, using the keywords bipolar and polypharmacy or bipolar and combination treatment and pharmacotherapy.Study Selection: From among 3,566 publications, 49 ultimately met study inclusion criteria.Data Extraction: Information was obtained regarding prevalence rates of extensive polypharmacy as well as clinical characteristics and naturalistic outcomes for patients with simple (≤ 2) or complex (≥ 3) regimens of psychotropic agents.Results: A weighted mean percentage of 32.7% of bipolar outpatients (4,535/13,863) taking ≥ 3 psychotropic medications was identified. Factors associated with complex polypharmacy use include female sex, White race, age > 50 years, history of psychosis, greater burden of depressive illness, subtherapeutic dosing, lower treatment adherence, more extensive psychiatric comorbidity, and a greater history of suicide attempts.Conclusions: Extensive or complex combination pharmacotherapy regimens are common in many patients with bipolar disorder and often reflect greater overall illness severity. Naturalistic studies do not point to better outcomes for patients receiving more complex drug regimens, suggesting likely confounding by indication, high severity, or comorbid conditions. Formal clinical trials are needed to identify optimal drug combinations and durations when using ≥ 3 psychotropic medications to treat patients with bipolar disorder.

Monotherapy in patients with pulmonary arterial hypertension at four German PH centres.

BACKGROUND: Although combination therapy is the gold standard for patients with pulmonary arterial hypertension (PAH), some of these patients are still being treated with monotherapy. METHODS: We conducted a retrospective analysis at four German PH centres to describe the prevalence and characteristics of patients receiving monotherapy. RESULTS: We identified 131 incident PAH patients, with a mean age of 64 ± 13.8 years and a varying prevalence of comorbidities, cardiovascular risk factors and targeted therapy. As in other studies, the extent of prescribed PAH therapy varied with age and coexisting diseases, and younger, so-called "typical" PAH patients were more commonly treated early with combination therapy (48% at 4-8 months). In contrast, patients with multiple comorbidities or cardiovascular risk factors were more often treated with monotherapy (69% at 4-8 months). Survival at 12 months was not significantly associated with the number of PAH drugs used (single, dual, triple therapy) and was not different between "atypical" and "typical" PAH patients (89% vs. 85%). CONCLUSION: Although "atypical" PAH patients with comorbidities or a more advanced age are less aggressively treated with respect to combination therapy, the outcome of monotherapy in these patients appears to be comparable to that of dual or triple therapy in "typical" PAH patients.

Cardiac Corrected QT Interval Changes Among Patients Treated for COVID-19 Infection During the Early Phase of the Pandemic.

Importance: Critical illness, a marked inflammatory response, and viruses such as SARS-CoV-2 may prolong corrected QT interval (QTc). Objective: To evaluate baseline QTc interval on 12-lead electrocardiograms (ECGs) and ensuing changes among patients with and without COVID-19. Design, Setting, and Participants: This cohort study included 3050 patients aged 18 years and older who underwent SARS-CoV-2 testing and had ECGs at Columbia University Irving Medical Center from March 1 through May 1, 2020. Patients were analyzed by treatment group over 5 days, as follows: hydroxychloroquine with azithromycin, hydroxychloroquine alone, azithromycin alone, and neither hydroxychloroquine nor azithromycin. ECGs were manually analyzed by electrophysiologists masked to COVID-19 status. Multivariable modeling evaluated clinical associations with QTc prolongation from baseline. Exposures: COVID-19, hydroxychloroquine, azithromycin. Main Outcomes and Measures: Mean QTc prolongation, percentage of patients with QTc of 500 milliseconds or greater. Results: A total of 965 patients had more than 2 ECGs and were included in the study, with 561 (58.1%) men, 198 (26.2%) Black patients, and 191 (19.8%) aged 80 years and older. There were 733 patients (76.0%) with COVID-19 and 232 patients (24.0%) without COVID-19. COVID-19 infection was associated with significant mean QTc prolongation from baseline by both 5-day and 2-day multivariable models (5-day, patients with COVID-19: 20.81 [95% CI, 15.29 to 26.33] milliseconds; P < .001; patients without COVID-19: -2.01 [95% CI, -17.31 to 21.32] milliseconds; P = .93; 2-day, patients with COVID-19: 17.40 [95% CI, 12.65 to 22.16] milliseconds; P < .001; patients without COVID-19: 0.11 [95% CI, -12.60 to 12.81] milliseconds; P = .99). COVID-19 infection was independently associated with a modeled mean 27.32 (95% CI, 4.63-43.21) millisecond increase in QTc at 5 days compared with COVID-19-negative status (mean QTc, with COVID-19: 450.45 [95% CI, 441.6 to 459.3] milliseconds; without COVID-19: 423.13 [95% CI, 403.25 to 443.01] milliseconds; P = .01). More patients with COVID-19 not receiving hydroxychloroquine and azithromycin had QTc of 500 milliseconds or greater compared with patients without COVID-19 (34 of 136 [25.0%] vs 17 of 158 [10.8%], P = .002). Multivariable analysis revealed that age 80 years and older compared with those younger than 50 years (mean difference in QTc, 11.91 [SE, 4.69; 95% CI, 2.73 to 21.09]; P = .01), severe chronic kidney disease compared with no chronic kidney disease (mean difference in QTc, 12.20 [SE, 5.26; 95% CI, 1.89 to 22.51; P = .02]), elevated high-sensitivity troponin levels (mean difference in QTc, 5.05 [SE, 1.19; 95% CI, 2.72 to 7.38]; P < .001), and elevated lactate dehydrogenase levels (mean difference in QTc, 5.31 [SE, 2.68; 95% CI, 0.06 to 10.57]; P = .04) were associated with QTc prolongation. Torsades de pointes occurred in 1 patient (0.1%) with COVID-19. Conclusions and Relevance: In this cohort study, COVID-19 infection was independently associated with significant mean QTc prolongation at days 5 and 2 of hospitalization compared with day 0. More patients with COVID-19 had QTc of 500 milliseconds or greater compared with patients without COVID-19.

Use of thyroid hormones in hypothyroid and euthyroid patients: A 2020 THESIS questionnaire survey of members of the Danish Endocrine Society.

PURPOSE: The standard treatment of hypothyroidism is levothyroxine (LT4), which is available as tablets or soft-gel capsules in Denmark. This study aimed to investigate Danish endocrinologists' use of thyroid hormones in hypothyroid and euthyroid patients. METHODS: An e-mail with an invitation to participate in an online survey investigating practices about substitution with thyroid hormones was sent to all members of the Danish Endocrine Society (DES). RESULTS: Out of 488 eligible DES members, a total of 152 (31.2%) respondents were included in the analysis. The majority (94.1%) of responding DES members use LT4 as the treatment of choice. Other treatment options for hypothyroidism are also used, as 58.6% prescribe combination therapy with liothyronine (LT3) + LT4 in their clinical practice. LT4 + LT3 combination is preferred in patients with persistent symptoms of hypothyroidism despite biochemical euthyroidism on LT4 treatment. Over half of the respondents answered that thyroid hormone therapy is never indicated for euthyroid patients, but 42.1% will consider it for euthyroid infertile women with high antibody levels. In various conditions that could interfere with the absorption of LT4, most responding Danish endocrinologists prefer tablets and do not expect a significant difference when switching from one type of tablet formulation to another. CONCLUSION: The treatment of choice for hypothyroidism is LT4. Combination therapy with LT4 + LT3 is considered for patients with persistent symptoms. Even in the presence of conditions affecting bioavailability, responding Danish endocrinologists prefer LT4 tablets rather than newer LT4 formulations, such as soft-gel capsules.

Over the Counter Products for Acne Treatment and Maintenance in Latin America: A Review of Current Clinical Practice.

BACKGROUND: The prevalence and clinical presentation of acne vulgaris in Latin America are comparable to that in Europe and the United States. This review aims at insight into the role of Over the Counter (OTC) products in acne treatment and maintenance in Latin America. METHODS: A panel of dermatologists from Latin America employed an online procedure to answer questions on this topic: What is used, by whom, when, how, and why? Before the meeting, a survey was completed by dermatologists from Latin America on OTC products for acne recommended by the panel in their clinical practice. The survey information and a literature review on Latin American acne guidelines and clinical studies were used to address this topic. RESULTS: The survey responders' choices on OTC products for monotherapy comprised alpha-hydroxy acid and beta-hydroxy acid-containing serum, ceramides-containing foaming cleanser, a soap-free exfoliating cleanser, adapalene, and benzoyl peroxide-containing products. The clinicians recommended OTC cleansing products mainly for younger patients at a starter level and for women with adult acne. The use of these OTC products is similar to practice described in therapeutic acne guidelines and algorithms for Latin American countries, Spain and Portugal, Europe, and the United States. CONCLUSIONS: Advisors agreed that OTC products and skincare recommendations, in addition to the use of prescription medications, are a crucial part of successful acne therapy. Participants noted that the use of quality OTC products could improve acne symptomatology and severity.

Virological failure and antiretroviral resistance among HIV-infected children after five years follow-up in the ANRS 12225-PEDIACAM cohort in Cameroon.

OBJECTIVE: In the present study, we aimed to evaluate the virological failure (VF) and drug resistance among treated HIV-infected children after five years follow-up in the ANRS-Pediacam cohort in Cameroon. METHODS: From November 2007 to October 2011, HIV-infected children born to HIV-infected mothers were included in the ANRS-PEDIACAM study and followed-up for more than 5 years. Plasma viral load (VL) was measured at each visit (every three months until month 24 and every 6 months thereafter). VF was the main outcome and HIV drug resistance test was performed using the ANRS procedures and algorithm. RESULTS: Data from 155 children were analyzed. The median age at combination antiretroviral therapy (cART) initiation was 4.2 months (interquartile range (IQR): 3.2-5.8), with 103 (66.5%) children taking LPV/r-containing regimen and 51 (32.9%) children taking NVP. After five years follow-up, 63 (40.6%; CI: 32.9-48.8) children experienced VF. The median duration between cART initiation and VF was 22.1 months (IQR: 11.9-37.1) with a median VL of 4.8 log10 (IQR: 4.0-5.5). Among the 57 children with HIV drug resistance results, 40 (70.2%) had at least one drug resistance mutation. The highest resistance rates (30.4-66.1%) were obtained with Lamivudine; Efavirenz; Nevirapine and Rilpivirine. CONCLUSIONS: These results show high resistance to NNRTI and emphasize the need of VL and resistance tests for optimal follow-up of HIV-infected people especially children.

Multicenter point prevalence evaluation of the utilization and safety of drug therapies for COVID-19 at the onset of the pandemic timeline in the United States.

KEY POINTS: In a multicenter point-prevalence study, we found that the rate of supportive care was high; among those receiving COVID-19 drug therapies, adverse reactions occurred in 12% of patients. PURPOSE: There are currently no FDA-approved medications for the treatment of coronavirus disease 2019 (COVID-19). At the onset of the pandemic, off-label medication use was supported by limited or no clinical data. We sought to characterize experimental COVID-19 therapies and identify safety signals during this period. METHODS: We conducted a noninterventional, multicenter, point prevalence study of patients hospitalized with suspected/confirmed COVID-19. Clinical and treatment characteristics within a 24-hour window were evaluated in a random sample of up to 30 patients per site. The primary objective was to describe COVID-19-targeted therapies. The secondary objective was to describe adverse drug reactions (ADRs). RESULTS: A total of 352 patients treated for COVID-19 at 15 US hospitals From April 18 to May 8, 2020, were included in the study. Most patients were treated at academic medical centers (53.4%) or community hospitals (42.6%). Sixty-seven patients (19%) were receiving drug therapy in addition to supportive care. Drug therapies used included hydroxychloroquine (69%), remdesivir (10%), and interleukin-6 antagonists (9%). Five patients (7.5%) were receiving combination therapy. The rate of use of COVID-19-directed drug therapy was higher in patients with vs patients without a history of asthma (14.9% vs 7%, P = 0.037) and in patients enrolled in clinical trials (26.9% vs 3.2%, P < 0.001). Among those receiving drug therapy, 8 patients (12%) experienced an ADR, and ADRs were recognized at a higher rate in patients enrolled in clinical trials (62.5% vs 22%; odds ratio, 5.9; P = 0.028). CONCLUSION: While we observed high rates of supportive care for patients with COVID-19, we also found that ADRs were common among patients receiving drug therapy, including those enrolled in clinical trials. Comprehensive systems are needed to identify and mitigate ADRs associated with experimental COVID-19 treatments.

Additive Intraocular Pressure-Lowering Effects of a Novel Selective EP2 Receptor Agonist, Omidenepag Isopropyl, Combined with Existing Antiglaucoma Agents in Conscious Ocular Normotensive Monkeys.

Purpose: To investigate the intraocular pressure (IOP)-lowering effects of omidenepag isopropyl (OMDI), a potent and highly selective prostanoid EP2 receptor agonist, as a potential first-line ocular hypotensive agent when combined with existing antiglaucoma agents in conscious ocular normotensive monkeys. Methods: Male cynomolgus monkeys were examined under conscious conditions. OMDI ophthalmic solution alone was topically applied to an eye or combined with other ophthalmic solutions at 5-min intervals. The contralateral eye was left untreated. IOP was measured before and at 2, 4, 6, and 8 h after instillation. Results: Topical application of OMDI to the eye resulted in statistically significant IOP reduction, which lasted for at least 6 h. The IOP-lowering effects of OMDI concomitantly administered with any of the tested antiglaucoma agents (timolol, brinzolamide, netarsudil, ripasudil, and brimonidine) were greater than those of OMDI alone. Furthermore, these enhanced IOP responses to their concomitant use were statistically significant compared with those of the tested antiglaucoma agents alone. Any combination of OMDI with the tested agents did not lead to serious abnormalities either systemically or locally in the eye. Conclusions: We demonstrated that OMDI has additive IOP-lowering effects when administered in combination with various antiglaucoma agents, namely, ß-adrenergic antagonist, carbonic anhydrase inhibitor, Rho-associated coiled-coil containing protein kinase inhibitors, and α2-adrenergic agonist. These results suggest that OMDI provides additional clinical benefits because of its unique mechanisms of action when combination therapy is required.

Adherence to triple-component antihypertensive regimens is higher with single-pill than equivalent two-pill regimens: A randomized controlled trial.

Using a single-pill combination (SPC) for hypertension (HTN) treatment resulted in better adherence and persistence than a free-equivalent combination in previous observational studies. The aim of this study is to confirm superior adherence with a triple-component SPC compared with an equivalent two-pill regimen in a randomized controlled trial (RCT) using a medication event monitoring system (MEMS). This is a multicenter, open-label, RCT. Subjects were persons with HTN whose clinic blood pressure was not adequately controlled (systolic >140 mmHg or diastolic >90 mmHg) with a dual combination. Eligible patients were randomized to either the triple-component SPC (olmesartan/amlodipine/hydrochlorothiazide 20/5/12.5 mg) group or the equivalent two-pill (olmesartan/hydrochlorothiazide 20/12.5 mg + amlodipine 5 mg) group and maintained for 12 weeks. Primary outcomes were the difference in percentage of doses taken (PDT) and percentage of days with the prescribed dose taken correctly (PDTc) between the single- and two-pill therapy groups, calculated from MEMS data. From 8 hospitals, 145 patients with HTN were randomized. The single-pill group had significantly higher PDT and PDTc than the two-pill group: median (25-75 percentile) PDT 95.1 (86.7-100.0) versus 92.1 (73.0-97.3); and PDTc 91.0 (79.4-96.5) versus 88.6 (69.2-96.3%), P = 0.04 for both by the Wilcoxon rank sum test. The single-pill combination of the triple-component antihypertensive regimen showed better adherence than the equivalent two-pill therapy. Reducing pill burden by means of a single-pill combination is an effective strategy for enhancing adherence to multiple-agent antihypertensive therapy. Study Highlights WHAT IS THE CURRENT KNOWLEDGE ON THE TOPIC? Previous studies suggested that the use of a single-pill combination (SPC) in hypertension (HTN) treatment produced better adherence and persistence than a free-equivalent combination. However, supportive data are confined to dual-component SPC and came from observational studies using medication possession ratio as an outcome. WHAT QUESTION DID THIS STUDY ADDRESS? The objective of this study is to investigate whether a triple-component SPC improved medication adherence over an equivalent two-pill combination therapy in a randomized controlled trial using medication event monitoring systems. WHAT DOES THIS STUDY ADD TO OUR KNOWLEDGE? Medication adherence in the SPC group was superior to that of two-pill group, confirming previous findings from observational studies. HOW MIGHT THIS CHANGE CLINICAL PHARMACOLOGY OR TRANSLATIONAL SCIENCE? This finding strongly supports the current HTN treatment guideline to prefer SPC with a higher level of evidence.

Factors associated with access and adherence to artemisinin-based combination therapy (ACT) for children under five: a secondary analysis of a national survey in Sierra Leone.

BACKGROUND: Access and adherence to artemisinin-based combination therapy (ACT) are key challenges to effective malaria treatment. A secondary analysis of the Sierra Leone malaria Knowledge, Attitudes, and Practices (mKAP) survey was conducted to investigate access and adherence to ACT for the treatment of fever in children under-five. METHODS: The mKAP was a nationally representative, two-stage cluster-sample survey, conducted in 2012. Thirty primary sampling units per district were randomly selected using probability proportionate to size, based on national census estimates; 14 households were subsequently randomly selected and enrolled per sampling unit. The analysis was restricted to children under-five with fever in the past two weeks. Factors associated with access and adherence were assessed using multivariate logistic regression. RESULTS: Of 5169 enrolled households, 1456 reported at least one child under-five with fever in the past two weeks. Of the 1641 children from these households, 982 (59.8%) received any treatment for fever and were analysed for access to ACT; 469 (47.6%) received ACT and 466 were analysed for treatment adherence. Only 222 (47.4%) febrile children received ACT and completed 3-day treatment. In an adjusted analysis, factors associated with ACT access included knowledge of ACT (odds ratio [OR] 2.78, 95% CI 2.02-3.80; p < 0.001), knowledge of insecticide-treated nets (ITNs) (OR 1.84, 95% CI 1.29-2.63; p = 0.001), source of care (public health facility vs. other; OR 1.86, 95% CI 1.27-2.72, p = 0.001), geographic region (East vs. West; OR 2.30, 95% CI 1.20-4.44; p = 0.025), and age (24-59 vs. 0-23 months; OR 1.45, 95% CI 1.07-1.96; p = 0.016). The only factor associated with ACT adherence was time to treatment; children treated within 24 h were less likely to adhere (OR 0.55, 95% CI 0.34-0.89; p = 0.015). CONCLUSIONS: In 2012, access and adherence to ACT remained low in Sierra Leone. Knowledge of ACT and ITNs, and seeking care in the public sector, were most strongly associated with ACT access. National surveys provide important information on anti-malarial access and could be expanded to measure treatment adherence.

European Registry on Helicobacter pylori management (Hp-EuReg): First-line Therapy in Israel.

BACKGROUND: The antibiotic resistance profile of Helicobacter pylori (H. pylori) is constantly changing. Up-to-date and reliable data for the effectiveness of first-line H. pylori treatment protocols are necessary to provide evidence-based best-practice guidelines. OBJECTIVES: To determine the effectiveness, compliance and safety of first-line treatment for H. pylori in Israel. METHODS: An observational, prospective, multicenter study was conducted in tertiary referral centers in Israel, as part of the European registry on H. pylori management (Hp-EuReg). H. pylori-infected patients were included from 2013 to March 2020. Data collected included demographics, clinical data, diagnostic tests, previous eradication attempts, current treatment, compliance, adverse events, and treatment outcome result. RESULTS: In total, 242 patients were registered, including 121 (50%) who received first-line therapy, 41% of these individuals received clarithromycin based triple therapy and 58.9% received a four-drug regimen. The overall effectiveness of first-line therapy was 85% and 86% by modified intention-to-treat and per protocol analyses, respectively. The effectiveness of both sequential and concomitant therapies was 100% while clarithromycin-based triple therapy achieved an eradication rate of 79%. Treatment eradication was higher among patients who received high dose proton pump inhibitor (PPI) compared to those treated with low dose PPI (100% vs. 81.5% respectively, P < 0.01). No difference in treatment effectiveness was found between 7-, 10-, and 14-day treatment. CONCLUSIONS: The effectiveness of clarithromycin-based triple therapy is suboptimal. First-line treatment of H. pylori infection should consist of four drugs, including high dose PPI, according to international guidelines.
