Advent of oral medications for the treatment of hereditary angioedema.

Hereditary angioedema (HAE) is a rare genetic disorder characterized by unpredictable, debilitating episodes of submucosal and/or subcutaneous tissue swelling, which may be life-threatening depending on anatomic location. The two primary management strategies for HAE are ready access to effective on-demand treatment in all patients and the prevention of attacks (short-term prophylaxis [STP] and long-term prophylaxis [LTP]) in appropriate patients. All approved on-demand and most LTP medications require subcutaneous or intravenous administration. Injection-related challenges include trypanophobia (fear of needles), difficulty with self-administration, injection-site reactions (e.g., pain, erythema, bleeding, bruising), and anxiety-all contributing to poor compliance and administration delays. Oral HAE treatments may improve outcomes by reducing treatment barriers. To review oral therapies, approved or in development, for on-demand treatment and/or prevention of HAE attacks. To provide a comprehensive review, data was obtained from publicly available resources through a targeted PubMed literature review and supplemented by information provided on company websites (search cutoff of May 31, 2024). Berotralstat, an oral plasma kallikrein (PKa) inhibitor, is approved for LTP. Sebetralstat, another PKa inhibitor, is the investigational first oral on-demand HAE treatment to complete a phase 3 trial. Deucrictibant, an oral bradykinin B2 receptor antagonist, has completed phase 2 trials for on-demand therapy and LTP. Several other oral PKa inhibitors (ATN249, VE-4666, and VE-4062) are in early development for LTP. Substantial advances have been made in the development of oral treatments for HAE. These treatments have the potential to improve and optimize clinical outcomes, satisfaction, and quality of life among patients with HAE.

Centralized care model for hereditary angioedema overcomes geographical barriers.

Hereditary angioedema due to C1 inhibitor deficiency (HAE) is a rare inborn error of immunity that presents with episodic swelling. Management is multifaceted and includes on-demand treatment of swelling episodes, short-term prophylaxis to prevent swelling episodes from procedures, and long-term prophylaxis (LTP) to prevent angioedema on an ongoing basis. All approved on-demand therapies are parenteral, necessitating patient training for home administration, particularly intravenous C1 inhibitor. These complexities can result in care gaps for rural HAE patients. We conducted a cross-sectional study at our Angioedema Center of Reference and Excellence to assess the care provided to urban and rural patients. The proportion of patients receiving LTP, proportion of patients diagnosed as children, and disease control measured using the Angioedema Control Test (AECT) were collected. Logistic and Poisson regression models adjusted for age and sex were used to compare the two groups. The proportion using LTP was similar at 62% and 61% in urban and rural patients, respectively (odds ratio [OR] 1.01 (CI 95% 0.34-2.99)). Among urban patients, 52% were diagnosed as children compared to 60% among rural residents (1.43 (0.37-5.56)). The mean (IQR) AECT score was 14.0 (8.5-15.5) in urban patients and 13.0 (10.0-14.0) in rural patients (Poisson β -0.001 (-0.23-0.23). These data indicate that rural patients received similar high-quality care. We attribute these findings to the centralized care model employed in which HAE patients in the region are seen at a single comprehensive care clinic.

The real life experience goes on: update after 4 years on the first cohort treated with lanadelumab at our center.

Lanadelumab is a first-line long-term prophylaxis (LTP) in hereditary angioedema (HAE). Real-life data on its long-term efficacy and safety are limited. It is unknown whether patients using lanadelumab need short-term prophylaxis (STP). To provide 4-year follow-up data for our first 34 patients treating with lanadelumab. Patients were assessed for their current injection interval, attacks, treatment satisfaction, disease control (AECT), quality of life impairment (AE-QoL), events that can induce attacks, and the use of STP since the start of their treatment with lanadelumab. Of 34 patients who started lanadelumab treatment, 32 were still using it after 4 years, with a median injection interval of 33 (range 14-90) days. HAE patients (n=28) reported longer intervals, i.e. 35 (14-90) days, than patients with angioedema due to acquired C1 inhibitor deficiency (n=4, 23 (14-31) days). With their current injection intervals, used for a mean duration of 29 ± 17 months, patients reported a yearly attack rate of 0.3 ± 0.1. More than 70% of patients were attack-free since starting their current injection interval. All patients reported well-controlled disease, i.e. ≥10 points in the AECT; 21 patients had complete control (16 points). AE-QoL scores improved further compared to our initial report, most prominently in the fears/shame domain (-6 points). Treatment satisfaction was very high. No angioedema occurred after 146 of 147 potentially attack-inducing medical procedures without STP. Our results demonstrate the long-term efficacy and safety of lanadelumab in real-life and question the need for STP in patients who use effective LTP.

Hereditary angioedema with normal C1-inhibitor: Clinical and genetic characterization of 15 Portuguese unrelated families

BackgroundHereditary angioedema with normal C1-inhibitor (HAE-nC1-INH) is a rare genetic disease with similar phenotype to HAE-C1-INH but different genetic background. Currently, 6 subtypes are recognized, based on the underlying mutations. Several aspects need further clarification. ObjectiveTo assess clinical features of patients with genetically characterized HAE-nC1-INH from the North of Portugal. MethodsRetrospective assessment of clinical data from all patients with HAE-nC1-INH followed at a HAE Reference Center. ResultsA total of 41 patients were identified, 4 with no family history. The FXII mutation Thr328Lys (38 carriers) was the most prevalent. There were 3 new potentially disease-causing variants linked to HAE-nC1-INH identified (c.529+4A>G:FXII; Cys248*:Kininogen-1; and Arg261His:Plasminogen). The HAE-FXII cohort included 82% females and 71.8% symptomatic patients. Penetrance rate was significantly higher in females (81.3% vs 28.6%; P = .012). A hormonal influence was observed in 96.2% of the symptomatic females, although 62.5% remained symptomatic after oral estrogen withdrawal. Trauma and dental procedures were frequent triggers (82.6% and 45.5%, respectively). Main locations were facial (described by 96%), lips (82.1%), and eyelids (64.3%). One patient reported erythema marginatum as prodrome. Plasma-derived C1-INH was effective as short-term prophylaxis in all treated patients, but only in 80% as on-demand treatment. Icatibant was effectively used on demand in 9 patients, but with relapses in 5 (57%). ConclusionWe described a large Portuguese series of patients with HAE-nC1-INH genetically characterized. Differences with others may contribute to improve current unmet needs and raise awareness of this rare disease. We highlighted the identification of 3 new variants (additional molecular studies are ongoing) and the report of erythema marginatum in HAE-nC1-INH.

Ceftriaxone to prevent early ventilator-associated pneumonia in patients with acute brain injury: a multicentre, randomised, double-blind, placebo-controlled, assessor-masked superiority trial

Patients with acute brain injury are at high risk of ventilator-associated pneumonia (VAP). The benefit of short-term antibiotic prophylaxis remains debated. We aimed to establish the effect of an early, single dose of the antibiotic ceftriaxone on the incidence of early VAP in patients with severe brain injury who required mechanical ventilation. PROPHY-VAP was a multicentre, randomised, double-blind, placebo-controlled, assessor-masked, superiority trial conducted in nine intensive care units in eight French university hospitals. We randomly assigned comatose (Glasgow Coma Scale score [GCS] ≤12) adult patients (age ≥18 years) who required mechanical ventilation for at least 48 h after acute brain injury to receive intravenous ceftriaxone 2 g or placebo once within the 12 h following tracheal intubation. Participants did not receive selective oropharyngeal and digestive tract decontamination. The primary outcome was the proportion of patients developing early VAP from the 2nd to the 7th day of mechanical ventilation, confirmed by masked assessors. The analysis was reported in the modified intention-to-treat population, which comprised all randomly assigned patients except those who withdrew or did not give consent to continue and those who did not receive the allocated treatment because they met a criterion for non-eligibility. The trial is registered with ClinicalTrials.gov, NCT02265406. From Oct 14, 2015, to May 27, 2020, 345 patients were randomly assigned (1:1) to receive ceftriaxone (n=171) or placebo (n=174); 330 received the allocated intervention and 319 were included in the analysis (162 in the ceftriaxone group and 157 in the placebo group). 166 (52%) participants in the analysis were men and 153 (48%) were women. 15 patients did not receive the allocated intervention after randomisation and 11 withdrew their consent. Adjudication confirmed 93 cases of VAP, including 74 early infections. The incidence of early VAP was lower in the ceftriaxone group than in the placebo group (23 [14%] vs 51 [32%]; hazard ratio 0·60 [95% CI 0·38-0·95], p=0·030), with no microbiological impact and no adverse effects attributable to ceftriaxone. In patients with acute brain injury, a single ceftriaxone dose decreased the risk of early VAP. On the basis of our findings, we recommend that an early, single dose of ceftriaxone be included in all bundles for the prevention of VAP in patients with brain injury who require mechanical ventilation.

Comparison of different regimens of short-term antibiotic prophylaxis in transrectal prostate biopsy

Prostate cancer is the most common malignant solid tumour in men aged >70 years and is the second most common cause of death from oncological circumstances. To evaluate the effect of different short-term prophylactic antibiotic regimens in transrectal prostate biopsy (PB) on the incidence of infectious complications. Patients who underwent transrectal ultrasound-guided PB between January 2021 and December 2022 were included in the prospective randomized study. According to the regimen of prophylaxis, patients were randomized into three groups: (1) fosfomycin trometamol 3g, 3h before the procedure+ ciprofloxacin 500mg, 2h before the procedure; (2) fosfomycin trometamol 3g, 3h before and 24h after the procedure; (3) ciprofloxacin 500mg 12, 2h before the procedure, and 12h after the procedure. A rectal swab was performed 1-2 weeks before PB to evaluate the culture findings. Complications were evaluated during follow-up visits within one month after PB. In the monitored period, 605PBs were performed, and 544 patients met the inclusion criteria (184, 161, and 199 in groups 1, 2, and 3). Infectious complications occurred in 10 cases (1.83%), namely 3, 4, and 3 according to patient groups. There was no statistically significant difference between the individual groups. None of the patients required hospitalization and all were free of symptoms of sepsis. Short-term antibiotic prophylaxis in PB using fosfomycin trometamol, ciprofloxacin, or their combination appears to be effective. Fosfomycin trometamol is a suitable alternative to fluoroquinolone antibiotics.

The role of anxiety in patients with hereditary angioedema during oral treatment: a narrative review.

The present study investigated the clinical potential of managing anxiety during dental procedures to reduce acute attacks in patients with hereditary angioedema (HAE). HAE is a rare disease, little known to physicians and dentists, but with an increased hospitalization rate over the years. HAE is due to a deficiency/dysfunction of the C1 esterase inhibitor, leading to increased vascular permeability. Recommendations for HAE management include long-term and short-term prophylaxis and treatment of acute attacks, but the importance of anxiety control is underestimated. The authors reviewed the literature to provide the scientific community with an overview of possible protocols for managing anxiety in dental practice and their effectiveness. Management can be used in prosthetics, periodontal and implant surgery, endodontics, and oral surgery. Our analysis shows that although there are few articles in the indexed literature, protocols for managing anxiety in HAE patients in dentistry will become increasingly prevalent in the daily clinical practice of dentists due to its benefits. The benefits and better control of intraoperative complications and risks may lead clinicians to use sedation, assessment, or anxiety control techniques in daily clinical practice to reduce such attacks. Clinical relevance: This study suggests that controlling and managing anxiety can help prevent and reduce acute angioedema attacks.

Real-world experience of hereditary angioedema (HAE) in Mexico: A mixed-methods approach to describe epidemiology, diagnosis, and treatment patterns

Introduction and objectivesDue to the lack of structured and systematic information available, the aim of this study was to describe the epidemiology, diagnosis, healthcare processes, and treatment patterns of hereditary angioedema (HAE) in Mexico. To achieve this, different data sources were consulted regarding medical literature, structured health system databases, and angioedema-specialized physicians (AEP) opinion regarding HAE. Material and methodsA mixed methods approach was conducted in 4 phases: I) systematic literature review (SLR) and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines; II) review of national health system (NHS) databases and systematic reports; III) physician survey; and IV) an epidemiologic model. ICD 10 D84.1 encoded records from the NHS were used to estimate the number of patients with HAE attended and treated during 2019. A survey was implemented to increase understanding of the clinical profile and treatments used. ResultsA prevalence rate of 0.9/50 000 inhabitants was estimated for 2019. In the same year, an estimated 317 HAE type 1 patients were recorded in the NHS, aged ≥11 years old. The most frequent clinical symptoms were cutaneous edema (67.5%) and abdominal pain (47.9%). A severe episode with laryngeal edema appeared in 27.5% of cases. Acute episodes were mainly moderate to severe (77.0%), with an annual per capita frequency of emergency visits of 7.6 patient-year (range 1–12/patient-year). The main reasons for hospitalization corresponded to laryngeal facial, tongue, and abdominal edemas, representing 73.3% of annual ICD 10 D84.1 reported hospitalizations. The main treatments that patients with HAE received were fresh frozen plasma for acute attacks and danazol for short-term prophylaxis (STP). ConclusionsDespite efforts to make HAE visible, according to this study, cases recognized and treated in the NHS represent only 16.6% of the estimated prevalence.

Preferred Therapy for Patients with Hereditary Angioedema during Pregnancy

Hereditary angioedema (HAE) is a rare, inherited disease caused by a deficiency (HAE-1) or lack of functional (HAE-2) C1 inhibitor protein. The symptoms present with mucocutaneous swelling of various organ systems, such as the respiratory and gastrointestinal systems, which can manifest as stridor and abdominal pain, respectively. HAE can present with increased frequency and severity of attacks during the pregnancy and lactation period. This is thought to be due to hormonal changes, which may trigger HAE attacks. The management of this condition in pregnant and lactating patients can be challenging for providers due to disease rarity and the lack of data regarding the management of this specific population. This review aims to provide insights for HAE management regarding rescue therapy, short-term prophylaxis, and long-term prophylaxis via the consolidation of the current literature and various international consensus guidelines. Furthermore, this review discusses when to initiate treatment and at what frequency and dosing, as well as the possible side effects that may occur as a result of therapy.

Treatment regimens, patient reported outcomes and health-related quality of life in children with moderate and severe hemophilia A in China: using real-world data

BackgroundProphylaxis therapy for children with moderate and severe hemophilia A (HA) is the optimal treatment regimen. The real-world treatment regimens, patient-reported outcomes, and health-related quality of life (HRQoL) in children with moderate and severe HA in China are less known.ObjectiveThis study aimed to describe real-world treatment regimens and evaluate the association of treatment regimens with comprehensive patient-reported outcomes including bleeds, chronic pain, target joints, disability, and HRQoL in children under 18 years old with HA in China.MethodsReal-world data of a nationwide online cross-sectional survey in 2021 and patients’ coagulation factor utilization data from self-management records from 2020 to 2021 were merged. 373 eligible children were included and categorized by treatment regimens according to the Chinese guideline: on-demand, short-term prophylaxis, and long-term prophylaxis treatment.ResultsCurrently, in China, 4.8% of children with HA are receiving full-dose long-term prophylaxis treatment. Prophylaxis treatment was a significant positive predictor of better patient-reported outcomes and HRQoL. For children with prophylaxis treatment, there were significantly fewer annual bleeds (p < 0.001), lower frequency of chronic pain(p < 0.001), and higher health utility scores(p < 0.01) and EQ-VAS scores(p < 0.05) than children with on-demand treatment.ConclusionAccessible long-term prophylaxis treatment should be promoted for children with moderate and severe HA in China and regular monitoring of their outcomes and HRQoL should be carried out.

Management of hereditary angioedema in resource-constrained settings: A consensus statement from Indian subcontinent.

Hereditary angioedema (HAE) is an uncommon disorder characterized clinically by recurrent episodes of nonitchy subcutaneous and/or submucosal swellings. The estimated prevalence of HAE is ~ 1: 10,000 to 1: 50,000. There are no prevalence data from India, however, estimates suggest that there are 27,000 to 135,000 patients with HAE in India at present. The majority of these, however, remain undiagnosed. Replacement of plasma-derived or recombinant C1-esterase inhibitor (C1-INH) protein, administered intravenously, is the treatment of choice during the management of acute episodes of angioedema (i.e., "on-demand treatment") and is also useful for short-term prophylaxis (STP) and long-term prophylaxis (LTP). This has been found to be effective and safe even in young children and during pregnancy. Until recently, none of the first-line treatment options were available for "on-demand treatment," STP or LTP in India. As a result, physicians had to use fresh frozen plasma for both "on-demand treatment" and STP. For LTP, attenuated androgens (danazol or stanozolol) and/or tranexamic acid were commonly used. These drugs have been reported to be useful for LTP but are associated with a significant risk of adverse effects. Intravenous pd-C1-INH, the first-line treatment option, is now available in India. However, because there is no universal health insurance, access to pd-C1-INH is a significant challenge. HAE Society of India has developed these consensus guidelines for India and other resource-constrained settings where plasma-derived C1-INH therapy is the only available first-line treatment option for the management of HAE and diagnostic facilities are limited. These guidelines have been developed because it may not be possible for all patients to access the recommended therapy and at the recommended doses as suggested by the international guidelines. Moreover, it may not be feasible to follow the evaluation algorithm suggested by the international guidelines.

Management of Hereditary Angioedema Type 1 and 2 for Canadian Allergy and Immunology Practitioners

It is imperative for allergists and immunologists to accurately confirm the diagnosis of HAE and coordinate individualized, patient-centred treatment. The 2019 International/Canadian Hereditary Angioedema Guideline, provides an evidence-based approach to managing HAE patients. The objective of this article is to further assist healthcare providers in caring for patients with a confirmed diagnosis of HAE by outlining an approach to patient counselling and reviewing the principles of therapy. We propose 5 essential items to consider in the management of all HAE patients: 1) Patient education; 2) On-demand therapy; 3) Short-term prophylaxis (STP); 4) Long-term prophylaxis (LTP); and 5) Genetic testing. We will also discuss special considerations for pregnant patients.

Current challenges and future opportunities in patient-focused management of hereditary angioedema: Anarrative review.

Patients with hereditary angioedema (HAE) experience a high burden of disease due to unpredictable, painful, disfiguring, and potentially life-threatening HAE attacks. Multiple HAE-specific medications for the on-demand treatment, short-term and long-term prophylaxis of HAE attacks have entered the market in recent years; however, the availability and access to these medications may vary between different countries. For this review, PubMed and EMBASE databases were searched for guidelines, consensus statements, and other publications on HAE management as well as publications on quality of life in patients with HAE. The current guidelines and recent literature on HAE management in specific countries are summarized with the aim to highlight the similarities and differences between guideline recommendations and the country-specific clinical practice. Improvement in quality of life, which is a key goal in HAE management, is also discussed and the country-specific trends are highlighted. Finally, the ways to achieve a more patient-centric approach to HAE management within the framework set by the clinical management guidelines are examined.

A Review of Randomized Controlled Trials of Hereditary Angioedema Long-Term Prophylaxis with C1 Inhibitor Replacement Therapy: Alleviation of Disease Symptoms Is Achievable.

Through its fluctuating disease activity and unpredictable attacks, hereditary angioedema (HAE) imposes a substantial patient burden. To minimize HAE burden and improve quality of life, treatment should involve individualized management strategies that address on-demand therapy and short-term/long-term prophylaxis. Goals of long-term prophylaxis include reducing the number, severity, and burden of HAE attacks. The best characterized forms of HAE arise from deficiency or dysfunction of C1-inhibitor (C1-INH; types I/II), and C1-INH replacement therapy is a first-line intervention for on-demand (acute) treatment of HAE attacks, short-term prophylaxis before high-risk procedures, and long-term prophylaxis. Randomized, double-blind, placebo-controlled crossover trials have shown dose-dependent efficacy with plasma-derived C1-INH (pdC1-INH) 40-60 IU/kg subcutaneously, pdC1-INH 1000 U intravenously, and recombinant human C1-INH (rhC1-INH) 50 IU/kg (maximum 4200 IU) intravenously, all administered twice weekly, as long-term prophylaxis in patients with a history of 2 to ≥4 attacks/month. Overall, up to 83% (pdC1-INH 60 IU/kg) of patients experienced an HAE attack reduction threshold of ≥70%, and up to 58% (pdC1-INH 60 IU/kg) achieved an attack reduction threshold of ≥90%. Lower-dose intravenous pdC1-INH therapy (1000 U) was seemingly less effective, with 45% of 22 patients experiencing an HAE attack reduction threshold of ≥70%, and up to 23% achieving an attack reduction threshold of ≥90%. Higher-dose intravenous rhC1-INH 50 IU/kg (maximum, 4200 IU) twice weekly was of intermediate benefit. Despite a baseline mean attack frequency of 17.9 (during the 3 months prior to study treatment) and a mean attack frequency during a 4-week placebo period of 7.2, 52% of 23 patients experienced ≥70% reduction in attack frequency and 26% of 23 patients experienced ≥90% reduction in attack frequency. The increasing patient percentages treated with C1-INH replacement therapy as long-term prophylaxis meeting these high thresholds reinforces hopes and expectations that "attack freedom" is achievable, including for those with moderate or severe disease.

Trends in Venous Thromboembolism Readmission Rates after Ischemic Stroke and Intracerebral Hemorrhage.

Venous thromboembolism (VTE) is a life-threatening complication of stroke. We evaluated nationwide rates and risk factors for hospital readmissions with VTE after an intracerebral hemorrhage (ICH) or acute ischemic stroke (AIS) hospitalization. Using the Healthcare Cost and Utilization Project (HCUP) Nationwide Readmission Database, we included patients with a principal discharge diagnosis of ICH or AIS from 2016 to 2019. Patients who had VTE diagnosis or history of VTE during the index admission were excluded. We performed Cox regression models to determine factors associated with VTE readmission, compared rates between AIS and ICH and developed post-stroke VTE risk score. We estimated VTE readmission rates per day over a 90-day time window post-discharge using linear splines. Of the total 1,459,865 patients with stroke, readmission with VTE as the principal diagnosis within 90 days occurred in 0.26% (3,407/1,330,584) AIS and 0.65% (843/129,281) ICH patients. The rate of VTE readmission decreased within first 4-6 weeks (P<0.001). In AIS, cancer, obesity, higher National Institutes of Health Stroke Scale (NIHSS) score, longer hospital stay, home or rehabilitation disposition, and absence of atrial fibrillation were associated with VTE readmission. In ICH, longer hospital stay and rehabilitation disposition were associated with VTE readmission. The VTE rate was higher in ICH compared to AIS (adjusted hazard ratio 2.86, 95% confidence interval 1.93-4.25, P<0.001). After stroke, VTE readmission risk is highest within the first 4-6 weeks and nearly three-fold higher after ICH vs. AIS. VTE risk is linked to decreased mobility and hypercoagulability. Studies are needed to test short-term VTE prophylaxis beyond hospitalization in high-risk patients.

Risk factors of active upper gastrointestinal bleeding in patients with COVID-19 infection and the effectiveness of PPI prophylaxis

BackgroundGastrointestinal (GI) bleeding is one of the most impactful complications in patients hospitalized from COVID-19 infection. Limited study has focused on patients with upper GI bleeding (UGIB). This study aimed to identify the risk factors of patients who were hospitalized from COVID-19 infection and developed UGIB as well as the effectiveness of proton pump inhibitor (PPI) prophylaxis in those patients.MethodsThis study was comprised of two phases. The first phase was the retrospective enrollment of patients who were admitted due to COVID-19 infection and developed UGIB between April and August 2021 to evaluate the associated factors of active UGIB. The second phase was a retrospective analysis after PPI prophylaxis protocol from September – October 2021 to assess the benefit of PPI use in those patients.ResultsOf 6,373 patients hospitalized, 43 patients (0.7%) had evidence of UGIB. The majority were male 28 (65.1%) with a mean age of 69.1 ± 11.8 years. Twenty-four of 43 patients (55.8%) needed mechanical ventilation, 35 patients (81.4%) received systemic corticosteroids, and 10 patients (23.3%) were taking anticoagulants for venous thromboembolic prophylaxis. Seven of 43 patients (16%) had active UGIB. There was no significant difference in the number of patients taking antiplatelets, anticoagulants, or steroids and the severity of COVID-19 infection between the two groups. An emergency endoscopy or endoscopic hemostasis were performed in 6/7 (85.7%) patients. The multivariate logistic regression analysis revealed two significant factors associated with active UGIB including higher of Glasgow-Blatchford score (GBS) per point (OR = 7.89; 95%CI 1.03–72.87; p = 0.04) and an absence of PPI use (OR 4.29; 95%CI 1.04–19.51; p = 0.04). After prescribing PPI as a prophylaxis, there was a slightly lower incidence of UGIB (0.6% vs 0.7%) in addition to an absence of active UGIB (0% vs 16%).ConclusionOur study demonstrated that the absence of PPI and higher GBS were significant risk factors for active UGIB which required therapeutic endoscopy in patients with COVID-19 infection. We suggest that short-term PPI prophylaxis should be prescribed in those patients once they need hospitalization regardless of the severity of COVID-19 infection to minimize the severity of UGIB.

Treatment of hereditary angioedema-single or multiple pathways to the rescue.

Hereditary angioedema (HAE) is a rare disease caused by mutations in the SERPING1 gene. This results in deficient or dysfunctional C1 esterase inhibitor (C1-INH) and affects multiple proteases involved in the complement, contact-system, coagulation, and fibrinolytic pathways. Current options for the treatment and prevention of HAE attacks include treating all affected pathways via direct C1-INH replacement therapy; or specifically targeting components of the contact activation system, in particular by blocking the bradykinin B2 receptor (B2R) or inhibiting plasma kallikrein, to prevent bradykinin generation. Intravenously administered plasma-derived C1-INH (pdC1-INH) and recombinant human C1-INH have demonstrated efficacy and safety for treatment of HAE attacks, although time to onset of symptom relief varied among trials, specific agents, and dosing regimens. Data from retrospective and observational analyses support that short-term prophylaxis with intravenous C1-INH products can help prevent HAE attacks in patients undergoing medical or dental procedures. Long-term prophylaxis with intravenous or subcutaneous pdC1-INH significantly decreased the HAE attack rate vs. placebo, although breakthrough attacks were observed. Pathway-specific therapies for the management of HAE include the B2R antagonist icatibant and plasma kallikrein inhibitors ecallantide, lanadelumab, and berotralstat. Icatibant, administered for treatment of angioedema attacks, reduced B2R-mediated vascular permeability and, compared with placebo, reduced the time to initial symptom improvement. Plasma kallikrein inhibitors, such as ecallantide, block the binding site of kallikrein to prevent cleavage of high molecular weight kininogen and subsequent bradykinin generation. Ecallantide was shown to be efficacious for HAE attacks and is licensed for this indication in the United States, but the labeling recommends that only health care providers administer treatment because of the risk of anaphylaxis. In addition to C1-INH replacement therapy, the plasma kallikrein inhibitors lanadelumab and berotralstat are recommended as first-line options for long-term prophylaxis and have demonstrated marked reductions in HAE attack rates. Investigational therapies, including the activated factor XII inhibitor garadacimab and an antisense oligonucleotide targeting plasma prekallikrein messenger RNA (donidalorsen), have shown promise as long-term prophylaxis. Given the requirement of lifelong management for HAE, further research is needed to determine how best to individualize optimal treatments for each patient.

Evaluating effects of the structural reform of outpatient psychotherapy for patients with mental disorders in Germany: comparing patients with and without comorbid chronic physical condition – rationale and study protocol of the ES-RiP project

IntroductionIn 2017, in Germany, a structural reform of the outpatient psychotherapy guideline took place, aiming to reduce waiting times, to facilitate flexible low-threshold access (eg, general reachability by phone) and...
