    OBJECTIVE: Haemophilia A (HA) is associated with high clinical and healthcare burden. We developed an Excel-based model comparing current practice to improved management in severe HA patients currently managed on demand (OD). Outcomes included short- and long-term bleed events. Expected annual bleeds were estimated based on locally-derived OD annualised bleed rate (ABR), adjusted by relative prophylaxis-related ABRs (published literature). The objective of our study was to explore the impact of improving HA prophylaxis in target countries with limited published data (Algeria, Argentina, Chile, India, Malaysia, Mexico, Taiwan and Thailand). Bleed-related healthcare resource use (HCRU) and costs were estimated as a function of bleed type, with inputs obtained from local expert estimates. Clotting factor concentrates (CFC) consumption related to treatment and prophylaxis was estimated based on locally relevant dosing. CFC costs were not included.

    RESULTS: When 20% of OD patients were switched to prophylaxis, projected reduction in bleeds was estimated between 3% (Taiwan) through 14% (Algeria and India); projected reductions in hospitalisations ranged from 3% (Taiwan) through 15% (India). Projected HCRU-related annual cost savings were estimated at USD 0.45 m (Algeria), 0.77 m (Argentina), 0.28 m (Chile), 0.13 m (India), 0.29 m (Malaysia), 2.79 m (Mexico), 0.15 m (Taiwan) and 0.78 m (Thailand). Net change in annual CFC consumption ranged from a 0.05% reduction (Thailand) to an overall 5.4% increase (Algeria). Our model provides a flexible framework to estimate the clinical and cost offsets of improved prophylaxis. Modest increase in CFC consumption may be an acceptable offset for improvements in health and healthcare capacity in resource constrained economies.

    PURPOSE: To evaluate the efficacy of topical tranexamic acid (TXA) in reducing intraoperative and immediate postoperative bleeding during functional endoscopic sinus surgery (FESS) among patients with chronic rhinosinusitis with nasal polyposis (CRSwNP).

    METHODS: This is a double-blind randomized clinical trial, involving 26 patients with CRSwNP, who underwent FESS for failed medical therapy. The intervention nostril was packed with ribbon gauze soaked in 500 mg/5 ml TXA. The control nostril was packed with ribbon gauze soaked in Moffett's solution, containing 2 ml 10% cocaine, 1 ml adrenaline 1:1000, and 4 ml 0.9% sodium bicarbonate. Both nostrils were packed for 15 min before FESS. Intraoperative bleeding was recorded in the initial 30 min after commencing the surgery. The recordings were reviewed by two surgeons using Boezaart's scoring system. The scores were taken at 15 and 30 min of surgery. The mean score was then calculated. At the end of the surgery, the intervention nostril was packed with Merocel® soaked in 500 mg/5 ml TXA and the control nostril was packed with Merocel® soaked in normal saline. The amount of bleeding within 24 h post-surgery was evaluated using a bolster gauze.

    RESULTS: There was no significant difference in intraoperative bleeding between the intervention (1.54 ± 0.71) and control nostrils (1.69 ± 0.55) with p = 0.172. The amount of bleeding in the postoperative period was significantly reduced in the intervention nostril (1.33 ± 0.55) compared to the control nostril saline (1.81 ± 0.48) with p = 0.001.

    CONCLUSIONS: We found that the nasal packing soaked in TXA reduced intraoperative and immediate postoperative bleeding. It is a safe, efficacious and cost-effective alternative to Moffett's solution during FESS and also an alternative to normal saline post-surgery among patients with CRSwNP.

    BACKGROUND: Perioperative bleeding is common in patients undergoing noncardiac surgery. Tranexamic acid is an antifibrinolytic drug that may safely decrease such bleeding.

    METHODS: We conducted a trial involving patients undergoing noncardiac surgery. Patients were randomly assigned to receive tranexamic acid (1-g intravenous bolus) or placebo at the start and end of surgery (reported here) and, with the use of a partial factorial design, a hypotension-avoidance or hypertension-avoidance strategy (not reported here). The primary efficacy outcome was life-threatening bleeding, major bleeding, or bleeding into a critical organ (composite bleeding outcome) at 30 days. The primary safety outcome was myocardial injury after noncardiac surgery, nonhemorrhagic stroke, peripheral arterial thrombosis, or symptomatic proximal venous thromboembolism (composite cardiovascular outcome) at 30 days. To establish the noninferiority of tranexamic acid to placebo for the composite cardiovascular outcome, the upper boundary of the one-sided 97.5% confidence interval for the hazard ratio had to be below 1.125, and the one-sided P value had to be less than 0.025.

    RESULTS: A total of 9535 patients underwent randomization. A composite bleeding outcome event occurred in 433 of 4757 patients (9.1%) in the tranexamic acid group and in 561 of 4778 patients (11.7%) in the placebo group (hazard ratio, 0.76; 95% confidence interval [CI], 0.67 to 0.87; absolute difference, -2.6 percentage points; 95% CI, -3.8 to -1.4; two-sided P<0.001 for superiority). A composite cardiovascular outcome event occurred in 649 of 4581 patients (14.2%) in the tranexamic acid group and in 639 of 4601 patients (13.9%) in the placebo group (hazard ratio, 1.02; 95% CI, 0.92 to 1.14; upper boundary of the one-sided 97.5% CI, 1.14; absolute difference, 0.3 percentage points; 95% CI, -1.1 to 1.7; one-sided P = 0.04 for noninferiority).

    CONCLUSIONS: Among patients undergoing noncardiac surgery, the incidence of the composite bleeding outcome was significantly lower with tranexamic acid than with placebo. Although the between-group difference in the composite cardiovascular outcome was small, the noninferiority of tranexamic acid was not established.

    During factor VIII prophylaxis for severe hemophilia A, bleeding risk increases with time when factor VIII activity is below 1%. Maintaining trough activity above 1% does not protect all patients from bleeding. The relationship between factor VIII activity during prophylaxis and bleeding risk has not been thoroughly studied. We investigated factor VIII activity and annualized bleeding rate for spontaneous bleeds during prophylaxis. A population pharmacokinetic model derived from three clinical trials was combined with dosing data and bleed information from patient diaries. Each patients' time on prophylaxis was divided into five categories of predicted activity (0-1%, >1-5%, >5-15%, >15-50%, and >50%). Exposure time, mean factor VIII activity, and bleed number (from patient diaries) were calculated for each activity category, and annualized bleeding rates estimated using negative binomial regression and a parametric model. Relationships between these bleeding rates and factor VIII activity were evaluated by trial phase (pivotal vs. extension) and age (adults/adolescents [≥12 years] vs. children [0-<12 years]). In total (N=187; 815 patient-years' exposure), factor VIII activity was predicted to reach >1% for 85.64% of the time. Annualized bleeding rate decreased as factor VIII activity increased in each trial phase and age group. However, for a given activity level, bleeding rate differed substantially by trial phase, and age. This suggests that bleeding risk can change over time and is influenced by factors independent of factor VIII pharmacokinetics and trough levels. Target trough and prophylactic regimen should consider patient age, joint disease activity, and other bleeding risk determinants.

    BACKGROUND: Primary endoscopic prophylaxis in pediatric gastroesophageal varices is not universally practiced. We aimed to determine the role of primary endoscopic prophylaxis in preventing variceal bleeding in gastroesophageal varices in children.

    METHODS: We reviewed all children with gastroesophageal varices seen in our unit from 2000 to 2019. Primary prophylaxis was defined as endoscopic procedure without a preceding spontaneous bleeding and secondary prophylaxis as preceded by spontaneous bleeding. High-risk varices were defined as presence of grade III esophageal varices, cardia gastric varices or cherry red spots on the varices. Outcome measures (spontaneous rebleeding within 3 months after endoscopic procedure, number of additional procedures to eradicate varices, liver transplant [LT], death) were ascertained.

    RESULTS: Sixteen of 62 (26%) patients (median [± S.D.] age at diagnosis = 5.0 ± 4.3 years) with varices had primary prophylaxis, 38 (61%) had secondary prophylaxis while 8 (13%) had no prophylaxis. No difference in the proportion of patients with high-risk varices was observed between primary (88%) and secondary (92%; P = 0.62) prophylaxis. As compared to secondary prophylaxis, children who had primary prophylaxis were significantly less likely to have spontaneous rebleeding (6% vs. 38%; P = 0.022) and needed significantly fewer repeated endoscopic procedures (0.9 ± 1.0 vs. 3.1 ± 2.5; P = 0.021). After 8.9 ± 5.5 years of follow-up, overall survival was 85%; survival with native liver was 73%. No statistical difference was observed in the eventual outcome (alive with native liver) between primary and secondary (71% vs. 78%, P = 0.78).

    CONCLUSION: Children with PHT who had primary prophylaxis had less subsequent spontaneous rebleeding and needed fewer additional endoscopic procedures as compared to secondary prophylaxis but did not have an improved eventual outcome. Screening endoscopy in all children who have signs of PHT and primary prophylaxis in high-risk esophageal varices should be considered before eventual LT.

    Rurioctocog alfa pegol prophylaxis targeting factor VIII (FVIII) troughs ≥1% has shown to be efficacious with an acceptable safety profile in people with hemophilia A (PwHA). The PROPEL trial compared safety and efficacy of 2 target FVIII troughs in PwHA aged 12 to 65 years, with severe disease, annualized bleeding rate ≥2, and previous FVIII treatment. PwHA were randomized to 12 months' pharmacokinetic (PK)-guided rurioctocog alfa pegol prophylaxis targeting FVIII troughs of 1% to 3% (reference arm) or 8% to 12% (elevated arm); first 6 months was treatment-adjustment period. The primary endpoint was absence of bleeds during the second 6 months, analyzed using multiple imputations (full analysis set [FAS]). In the 1% to 3% and 8% to 12% arms, respectively, point estimates (95% confidence interval) of proportions of PwHA with zero total bleeds were 42% (29% to 55%) and 62% (49% to 75%) in FAS (N = 115; P = .055) and 40% (27% to 55%) and 67% (52% to 81%) in per-protocol analysis set (N = 95; P = .015). Dosing frequency and consumption varied in each arm. Adverse events (AEs) occurred in 70/115 (60.9%) PwHA; serious AEs in 7/115 (6%) PwHA, including 1 treatment-related in 8% to 12% arm (transient anti-FVIII inhibitor). There were no deaths, serious thrombotic events, or AE-related discontinuations. PK-guided prophylaxis was achievable and efficacious in both arms. No new safety signals were observed in the 8% to 12% arm. These results demonstrate elevated FVIII troughs can increase the proportion of PwHA with zero bleeds and emphasize the importance of personalized treatment. This trial was registered at www.clinicaltrials.gov as #NCT02585960.

    OBJECTIVES: Perioperative bleeding remains a major concern to all clinicians caring for perioperative patients. Due to the theoretical risk of thromboembolic events associated with tranexamic acid (TXA) when administered intravenously, topical route of TXA has been extensively studied, but its safety and efficacy profile remain unclear in the literature. The primary aim of this review was to assess the effect of topical TXA on incidence of blood transfusion and mortality in adults undergoing surgery.

    DATA SOURCES: EMBASE, MEDLINE, CENTRAL, and ISI Web of Science were systematically searched from their inception until May 31, 2019.

    REVIEW METHODS: Parallel-arm randomized controlled trials were included.

    RESULTS: Seventy-one trials (7539 participants: orthopedics 5450 vs nonorthopedics 1909) were included for quantitative meta-analysis. In comparison to placebo, topical TXA significantly reduced intraoperative blood loss [mean difference (MD) -36.83 mL, 95% confidence interval (CI) -54.77 to -18.88, P < 0.001], total blood loss (MD -319.55 mL, 95% CI -387.42 to -251.69, P < 0.001), and incidence of blood transfusion [odds ratio (OR) 0.30, 95% CI 0.26-0.34, P < 0.001]. Patients who received topical TXA were associated with a shorter length of hospital stay (MD -0.28 days, 95% CI -0.47 to -0.08, P = 0.006). No adverse events associated with the use of topical TXA were observed, namely mortality (OR 0.78, 95% CI 0.45-1.36, P = 0.39), pulmonary embolism (OR 0.73, 95% CI 0.27-1.93, P = 0.52), deep vein thrombosis (OR 1.07, 95% CI 0.65-1.77, P = 0.79), myocardial infarction (OR 0.79, 95% CI 0.21-2.99, P = 0.73), and stroke (OR 0.85, 95% CI 0.28-2.57, P = 0.77). Of all included studies, the risk of bias assessment was "low" for 20 studies, "unclear" for 26 studies and "high" for 25 studies.

    CONCLUSIONS: In the meta-analysis of 71 trials (7539 patients), topical TXA reduced the incidence of blood transfusion without any notable adverse events associated with TXA in adults undergoing surgery.

    BACKGROUND: Low level of fibrinogen is a risk factor of perioperative bleeding, which is a major complication in surgical patients. However, the safety and efficacy of fibrinogen supplementation with fibrinogen concentrate to minimize postoperative bleeding remains unclear.

    OBJECTIVES: The primary aim of this review was to investigate the effect of fibrinogen concentrate in postoperative blood loss in adult surgical patients.

    DESIGN: Systematic review and meta-analysis.

    DATA SOURCES: Databases of MEDLINE, EMBASE and CENTRAL were searched from their start date until July 2019.

    ELIGIBILITY CRITERIA: All randomized clinical trials comparing intravenous fibrinogen concentrate and placebo in adult surgical patients were included, regardless of type of surgery. Observational studies, case reports, case series and non-systematic reviews were excluded.

    RESULTS: Thirteen trials (n = 900) were included in this review. In comparison to placebo, fibrinogen concentrate significantly reduced the first 12-hour postoperative blood loss, with a mean difference of -134.6 ml (95% CI -181.9 to -87.4). It also significantly increased clot firmness in thromboelastometry (FIBTEM) with a mean difference of 2.5 mm (95%CI 1.1 to 3.8). No significant differences were demonstrated in the adverse events associated with fibrinogen concentrate use, namely incidence of thromboembolism, myocardial infarction and acute kidney injury.

    CONCLUSIONS: In this meta-analysis of 13 randomized trials, low level of evidence and substantial heterogeneity with small sample size limit strong recommendation on the use of fibrinogen concentrate in adult surgical patients. However, its use is tolerable without any notable adverse events.

    BACKGROUND: Cystic fibrosis is an autosomal recessive inherited defect in the cystic fibrosis transmembrane conductance regulator (CFTR) gene resulting in abnormal regulation of salt and water movement across the membranes. In the liver this leads to focal biliary fibrosis resulting in progressive portal hypertension and end-stage liver disease in some individuals. This can be asymptomatic, but may lead to splenomegaly and hypersplenism, development of varices and variceal bleeding, and ascites; it has negative impact on overall nutritional status and respiratory function in this population. Prognosis is poor once significant portal hypertension is established. The role and outcome of various interventions for managing advanced liver disease (non-malignant end stage disease) in people with cystic fibrosis is currently unidentified. This is an updated version of a previously published review.

    OBJECTIVES: To review and assess the efficacy of currently available treatment options for preventing and managing advanced liver disease in children and adults with cystic fibrosis.

    SEARCH METHODS: We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. Date of last search: 19 November 2019. We also searched the reference lists of relevant articles and reviews and online trials registries. Date of last search: 01 January 2020.

    SELECTION CRITERIA: Any published and unpublished randomised controlled trials and quasi-randomised controlled trials of advanced liver disease in cystic fibrosis with cirrhosis or liver failure, portal hypertension or variceal bleeding (or both).

    DATA COLLECTION AND ANALYSIS: Authors independently examined titles and abstracts to identify potentially relevant trials, but none were eligible for inclusion in this review.

    MAIN RESULTS: A comprehensive search of the literature did not identify any published eligible randomised controlled trials.

    AUTHORS' CONCLUSIONS: In order to develop the best source of evidence, there is a need to undertake randomised controlled trials of interventions for preventing and managing advanced liver disease in adults and children with cystic fibrosis.

    BACKGROUND: In order to prove the idea that topical application of drugs can improve the clinical parameters affecting periodontal disease, a sound comparison should be made between topical therapeutic models. The aim of the present study was to assess the clinical efficacy of photodynamic therapy (PDT) and Salvadora persica (SP) gel as adjuncts to scaling and root planning (SRP) in the treatment of chronic periodontitis.

    METHODS: The selected patients were divided into three groups, Group I (PDT + SRP), Group II (SP + SRP) and group III (SRP alone). Clinical inflammatory periodontal parameters including plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment level (CAL) gain were assessed. Assessment of crevicular fluid interleukin (IL)-6 and tumor necrosis factor alpha (TNF-α) was performed using enzyme-linked immunosorbent assay technique. All measurements were recorded at baseline, 3 months and 6 months follow-up periods, respectively.

    RESULTS: A total of 73 patients completed the study. A significant improvement in the BOP was seen in Group II at both follow up visits when compared with other groups (p < 0.05). Only in Group-I that showed statistically significant reduction in moderate periodontal pockets at 3 months (p = 0.021), and significant reductions in deep pockets at 3-months (p = 0.003) and 6-months (p = 0.002), respectively. CAL gain also was reported to be seen in group-I at both visits (p < 0.05). Group- I and II significantly reduced the levels of IL-6 at 3-month period compared to Group-III. This reduction was further maintained by group-II and group-III at 6 months, respectively. TNF-α showed statistically significant decrease in Group II as compared to Group I and Group-III and this reduction was maintained by the end of 6-month visit (p = 0.045).

    CONCLUSION: Both the treatment modalities PDT and SP helped in reducing periodontal inflammation. PDT reported significant gain in clinical attachment level, whereas the SP significantly reduced the bleeding levels.

    Warfarin care bundles (e.g. genotype-guided warfarin dosing, patient's self-testing [PST] or patient's self-management [PSM] and left atrial appendage closure) are based on the concept of combining several interventions to improve anticoagulation care. NOACs are also introduced for stroke prevention in atrial fibrillation (SPAF). However, these interventions have not been compared in head-to-head trials yet. We did a network meta-analysis based on a systematic review of randomized controlled trials comparing anticoagulant interventions for SPAF. Studies comparing these interventions in adults, whether administered alone or as care bundles were included in the analyses. The primary efficacy outcome was stroke and the primary safety outcome was major bleeding. Thirty-seven studies, involving 100,142 patients were assessed. Compared to usual care, PSM significantly reduced the risk of stroke (risk ratio [RR] 0.24, 95% CI 0.08-0.68). For major bleeding, edoxaban 60 mg (0.80, 0.71-0.90), edoxaban 30 mg (0.48, 0.42-0.56), and dabigatran 110 mg (0.81, 0.71-0.94) significantly reduced the risk of major bleeding compared with usual warfarin care. Cluster rank plot incorporating stroke and major bleeding outcomes indicates that some warfarin care bundles perform as well as NOACs. Both interventions are therefore viable options to be considered for SPAF. Additional studies including head-to-head trials and cost-effectiveness evaluation are still warranted.

    BACKGROUND & AIMS: Proton pump inhibitors (PPIs) are effective at treating acid-related disorders. These drugs are well tolerated in the short term, but long-term treatment was associated with adverse events in observational studies. We aimed to confirm these findings in an adequately powered randomized trial.

    METHODS: We performed a 3 × 2 partial factorial double-blind trial of 17,598 participants with stable cardiovascular disease and peripheral artery disease randomly assigned to groups given pantoprazole (40 mg daily, n = 8791) or placebo (n = 8807). Participants were also randomly assigned to groups that received rivaroxaban (2.5 mg twice daily) with aspirin (100 mg once daily), rivaroxaban (5 mg twice daily), or aspirin (100 mg) alone. We collected data on development of pneumonia, Clostridium difficile infection, other enteric infections, fractures, gastric atrophy, chronic kidney disease, diabetes, chronic obstructive lung disease, dementia, cardiovascular disease, cancer, hospitalizations, and all-cause mortality every 6 months. Patients were followed up for a median of 3.01 years, with 53,152 patient-years of follow-up.

    RESULTS: There was no statistically significant difference between the pantoprazole and placebo groups in safety events except for enteric infections (1.4% vs 1.0% in the placebo group; odds ratio, 1.33; 95% confidence interval, 1.01-1.75). For all other safety outcomes, proportions were similar between groups except for C difficile infection, which was approximately twice as common in the pantoprazole vs the placebo group, although there were only 13 events, so this difference was not statistically significant.

    CONCLUSIONS: In a large placebo-controlled randomized trial, we found that pantoprazole is not associated with any adverse event when used for 3 years, with the possible exception of an increased risk of enteric infections. ClinicalTrials.gov Number: NCT01776424.

    BACKGROUND & AIMS: Antiplatelets and anticoagulants are associated with increased upper gastrointestinal bleeding. We evaluated whether proton pump inhibitor therapy could reduce this risk.

    METHODS: We performed a 3 × 2 partial factorial double-blind trial of 17,598 participants with stable cardiovascular disease and peripheral artery disease. Participants were randomly assigned to groups given pantoprazole 40 mg daily or placebo, as well as rivaroxaban 2.5 mg twice daily with aspirin 100 mg once daily, rivaroxaban 5 mg twice daily, or aspirin 100 mg alone. The primary outcome was time to first upper gastrointestinal event, defined as a composite of overt bleeding, upper gastrointestinal bleeding from a gastroduodenal lesion or of unknown origin, occult bleeding, symptomatic gastroduodenal ulcer or ≥5 erosions, upper gastrointestinal obstruction, or perforation.

    RESULTS: There was no significant difference in upper gastrointestinal events between the pantoprazole group (102 of 8791 events) and the placebo group (116 of 8807 events) (hazard ratio, 0.88; 95% confidence interval [CI], 0.67-1.15). Pantoprazole significantly reduced bleeding of gastroduodenal lesions (hazard ratio, 0.52; 95% confidence interval, 0.28-0.94; P = .03); this reduction was greater when we used a post-hoc definition of bleeding gastroduodenal lesion (hazard ratio, 0.45; 95% confidence interval, 0.27-0.74), although the number needed to treat still was high (n = 982; 95% confidence interval, 609-2528).

    CONCLUSIONS: In a randomized placebo-controlled trial, we found that routine use of proton pump inhibitors in patients receiving low-dose anticoagulation and/or aspirin for stable cardiovascular disease does not reduce upper gastrointestinal events, but may reduce bleeding from gastroduodenal lesions.

    OBJECTIVE: Approximately one-third of patients with esophageal varices will develop bleeding which is a major cause of morbidity and mortality in patients with liver cirrhosis. Currently, the two most widely used modalities to prevent variceal bleeding are pharmacologic and oendoscopic variceal band ligation (EVL). However, EVL has been associated with significant complications. Hence we aim to evaluate and to identify the epidemiology, demography, and complications of EVL at our local Malaysian tertiary hospital.

    METHOD: This is a retrospective study of all the patients that had undergone endoscopic variceal surveillance at the Gastroenterology endoscopy unit, Serdang Hospital from 1st January 2015 to 31st March 2017. Patients' demography, aetiologies of liver cirrhosis, platelet level and international normalised ratio (INR) prior banding procedure, and the post EVL complications were recorded and further analysed with SPSS version 16.

    RESULTS: In this study, 105 patients were screened for varices. Fifty-five of them had undergone EVL, with a quarter of the patients requiring repeated ligation. There was a male preponderance with 76.4%. 56.4% of patients were in age from 40-59 years. The majority of our patients were of the Malay ethnicity. The major aetiology for liver cirrhosis in our patients was viral hepatitis with Hepatitis C (31.0%), and Hepatitis B (20.0%). Most of our patients had platelet count >50,000 and INR <1.5 prior to EVL. There was no major complication in all of our subjects.

    CONCLUSION: EVL is relatively safe and feasible treatment for prevention of oesophageal variceal bleeds with a low complication rate.

    OBJECTIVE: Postpartum hemorrhage remains the leading cause of maternal mortality in developing countries and a significant proportion of these cases are attributable to uterine atony. In contrast to the advances made in the treatment of postpartum hemorrhage, there has been few novel prophylactic agents. This study was undertaken to analyze the effectiveness of carbetocin compared to oxytocin for the prevention of postpartum hemorrhage, in the context of cesarean deliveries.

    MATERIALS AND METHODS: Major electronic databases were searched for randomized-controlled trials comparing carbetocin with oxytocin. Only trials involving cesarean deliveries were included. Non-randomized trials, non-cesarean deliveries, studies which did not directly compare carbetocin to oxytocin and studies which did not analyze the intended outcomes were excluded. Outcomes analysed were postpartum hemorrhage, additional use of uterotonic and transfusion requirement.

    RESULTS: Seven studies involving 2012 patients were included in the meta-analysis. There was a significant reduction in the rates of postpartum hemorrhage (RR 0.79; 95% CI 0.66 to 0.94; p = 0.009), use of additional uterotonics (RR 0.57; 95% CI 0.49 to 0.65; p

    AIM: To evaluate the cost effectiveness of carbetocin compared to oxytocin when used as prophylaxis against post-partum hemorrhage (PPH) during cesarean deliveries.

    METHODS: A systematic review of the literature was performed to identify randomized controlled trials that compared the use of carbetocin to oxytocin in the context of cesarean deliveries. Cost effectiveness analysis was then performed using secondary data from the perspective of a maternity unit within the Malaysian Ministry of Health, over a 24 h time period.

    RESULTS: Seven randomized controlled trials with over 2000 patients comparing carbetocin with oxytocin during cesarean section were identified. The use of carbetocin in our center, which has an average of 3000 cesarean deliveries annually, would have prevented 108 episodes of PPH, 104 episodes of transfusion and reduced the need for additional uterotonics in 455 patients. The incremental cost effectiveness ratio of carbetocin for averting an episode of PPH was US$278.70.

    CONCLUSION: Reduction in retreatment, staffing requirements, transfusion and potential medication errors mitigates the higher index cost of carbetocin. From a pharmacoeconomic perspective, in the context of cesarean section, carbetocin was cost effective as prophylaxis against PPH. Ultimately, the relative value placed on the outcomes above and the individual unit's resources would influence the choice of uterotonic.

    BACKGROUND: N8-GP (turoctocog alfa pegol) is an extended half-life glycoPEGylated recombinant factor VIII (FVIII) product developed for the prevention and treatment of bleeds in haemophilia A patients.

    AIM: This is a planned interim analysis of pathfinder™3, an international, open-label, Phase 3 trial evaluating the efficacy and safety (including immunogenicity) of N8-GP administered before, during and after major surgery in severe haemophilia A patients aged ≥12 years.

    METHODS: Sixteen patients who underwent 18 major surgical procedures (including synovectomy, joint replacement and ankle arthrodesis) were included here. Postoperative assessments were conducted daily for days 1-6, and once for days 7-14. Primary endpoint was N8-GP haemostatic efficacy, assessed after completion of surgery using a four-point scale ('excellent', 'good', 'moderate', 'none').

    RESULTS: Haemostasis was successful (rated 'excellent' or 'good') on completion of surgery in 17 (94.4%) procedures and rated as 'moderate' (5.6%) for one surgery in a patient with multiple comorbidities who needed an intraoperative N8-GP dose (20.7 IU kg-1 ). In the postoperative period, three bleeds occurred (one during days 1-6; two during days 7-14); all were successfully treated with N8-GP. Mean N8-GP consumption on day of surgery was 80.0 IU kg-1 ; patients received a mean of 1.7 doses (median: 2, range: 1-3). No safety concerns were identified.

    CONCLUSION: The data showed that N8-GP was effective and well tolerated for the prevention and treatment of bleeds during major surgery; such FVIII products with extended half-lives may modify current treatment schedules, enabling fewer infusions and earlier patient discharge.

    Both proton pump inhibitors (PPIs) and clopidogrel are widely prescribed in the Asia-Pacific population. PPIs are the mainstay therapeutic agents for prophylaxis against aspirin gastropathy and for acid-related disorders including gastroesophageal reflux disease. They are also co-prescribed with oral anticoagulant agents and with dual-antiplatelet therapy for the treatment and prevention of gastrointestinal bleeding. Clopidogrel belongs to the drug class of thienopyridines and is currently the most widely prescribed oral anticoagulant agent either alone or in combination with aspirin. Platelet inhibition by clopidogrel is prone to significant inter-individual variability and is believed to be affected by several factors such as genetics and drug-drug interactions. Since it was first reported in 2009, the potential for drug-drug interactions between PPIs and clopidogrel has remained headline news, and its significance in clinical practice is the subject of an ongoing debate. For East Asian patients in particular, the clinical relevance of the interaction between PPIs and clopidogrel remains unclear because of conflicting data, as well as underrepresentation of East Asian subjects in landmark trials. Increased CYP2C19 genetic polymorphisms in individuals from Asia-Pacific countries only fuel the confusion. Recent studies in East Asian cohorts suggests that the potential of PPIs to attenuate the efficacy of clopidogrel could be minimized by the use of newer PPIs with weaker affinity for the CYP2C19 isoenzyme, namely, pantoprazole, dexlansoprazole, and rabeprazole. This review aims to help clinicians choose the most appropriate PPI for co-prescription with clopidogrel in patients from Asia-Pacific countries.

    The Asian venous thromboembolism (VTE) prophylaxis guidelines were first published in 2012. Since its first edition, the Asian Venous Thrombosis Forum (AVTF) working group have updated the Asian VTE epidemiology and reviewed issues that were not addressed in the previous guidelines. The authors noted that the rising incidence of VTE across Asia may be attributable to aging population, dietary changes, and increasing incidence of obesity and diabetes. The new additions in the guideline include role of thrombophilia in VTE, bleeding risk in Asians, individual risk assessment, updates in the prevention of VTE in medically ill, bariatric surgery, cancer, orthopedic and trauma patients. The influence of primary thrombophilia in perioperative VTE is still unclear. The secondary risk factors, however, are similar between Asians and Caucasians. The group found no evidence of increased risk of bleeding while using pharmacological agents, including the use of novel anti-coagulants. At present, Caprini risk assessment model is widely used for individual risk assessment. Further validation of this model is needed in Asia. In medically ill patients, pharmacological agents are preferred if there is no bleeding risk. Intermittent pneumatic compression device (IPC) is recommended in patients with bleeding risk but we do not recommend using graduated compressive stockings. In bariatric patients, data on VTE is lacking in Asia. We recommend following current international guidelines. A high index of suspicion should be maintained during postbariatric surgery to detect and promptly treat portomesenteric venous thrombosis. Different cancer types have different thrombotic risks and the types of surgery influence to a large extent the overall VTE risk. Cancer patients should receive further risk assessment. In patients with higher thrombotic risk, either due to predisposing risk or concomitant surgery, low molecular weight heparin is indicated. Different countries appear to have different incidence of VTE following trauma and major orthopedic surgery. We recommend mechanical prophylaxis using IPC as the main method and additional pharmacological prophylaxis if the thrombotic risk is high. As for obstetric practice, we propose adherence to the UK Greentop guideline that is widely accepted and utilized across Asia. To improve VTE thromboprophylaxis implementation in the region, we propose that there should be better health education, establishment of hospital-based guidelines and multidisciplinary collaboration.

    Patients with chronic kidney disease (CKD) are at increased risk for both thrombotic events and bleeding. The early stages of CKD are mainly associated with prothrombotic tendency, whereas in its more advanced stages, beside the prothrombotic state, platelets can become dysfunctional due to uremic-related toxin exposure leading to an increased bleeding tendency. Patients with CKD usually require anticoagulation therapy for treatment or prevention of thromboembolic diseases. However, this benefit could easily be offset by the risk of anticoagulant-induced bleeding. Treatment of patients with CKD should be based on evidence from randomized clinical trials, but usually CKD patients are excluded from these trials. In the past, unfractionated heparins were the anticoagulant of choice for patients with CKD because of its independence of kidney elimination. However, currently low-molecular-weight heparins have largely replaced the use of unfractionated heparins owing to fewer incidences of heparin-induced thrombocytopenia and bleeding. We undertook this review in order to explain the practical considerations for the management of anticoagulation in these high risk population.
