Abstract
Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) is caused by mutations affecting the SERPING1 gene. Adult patients (≥ 18 years old) diagnosed with C1-INH-HAE were clustered according to a modified SERPING1 gene mutation classification [5]. Demographic, clinical, and laboratory data were studied. Published manuscripts on the genotype/phenotype relationship were reviewed. Eighty-eight patients participated in the study, with 78 having a classifiable mutation. We compared the data in the 3 largest groups: class 0 only (n = 32), class II only (n = 18), class III only (n = 22). Antigenic C4 and C1 inhibitors were higher in class II (p = 0.008 and p = 0.02, respectively), and facial attacks in the last 6 months were more frequent in class III (p = 0.04)). All the other differences were non-significant. Twelve manuscripts on phenotype/genotype correlation were found: missense mutations in SERPING1 gene were associated with delay in disease onset and lower severity score in some studies, whereas the CC F12-C46T/C polymorphism produced earlier disease onset. Our study shows minimal differences regarding clinical phenotype in patients with class 0, II, and III SERPING1 gene mutations, with a tendency to class III having a more severe phenotype. The study should be performed in a larger sample to confirm if they are significant.We propose that larger multicenter, international studies are performed, comparing different SERPING1 gene mutation classifications, combining polymorphisms in other involved genes (kallikrein-kinin system, regulation of vasculature, plasminogen activation) and using different variables and clinical scores to assess C1-INH-HAE disease activity and/or severity in order to study possible genotype/phenotype relationships.

Abstract
Hereditary Angioedema (HAE) is an autosomal dominant disorder characterized clinically by recurrent episodes of swelling involving subcutaneous tissues, gastrointestinal tract, and oro-pharyngeal area. Gene mutations are the most common genetic cause of HAE and observed in more than 90% of patients. More than 700 mutation variants have been described so far. Patients with angioedema who have no mutations in the gene for C1-INH and normal levels and activity of this inhibitor are labelled: normal C1 inhibitor HAE. These include genetic mutations in factor 12 gene, plasminogen gene, angiopoietin gene, kininogen 1, and myoferlin genes. The clinical manifestations of patients with these mutations are similar to with patients with C1-INH gene mutations. However, a later age of onset, oro-pharyngeal involvement, and higher female preponderance have been reported in these rare subtypes of hereditary angioedema. With the advent and increased accessibility of whole-exome sequencing, it is expected that new genetic defects and novel pathophysiological pathways will be identified in families with HAE of unknown cause or normal C1-INH angioedema. This review covers some of the recent advances in the field of HAE. The review focuses on pathophysiology of HAE beyond the well-known C1-INH deficiency phenotypes, including various biomarkers that can serve the diagnosis and management of these rare disorders.

Abstract
BACKGROUND Physician surveys on hereditary angioedema (HAE) management in 2010 and 2013 revealed important trends in HAE care. OBJECTIVE To evaluate current HAE management and the impact of new treatment options on physician practice patterns over time. METHODS During June and July 2019, 5382 physicians were contacted by means of postal mail to complete a 47-question survey; 177 responded (3%). RESULTS Across the 3 surveys, the home replaced the emergency department as the most typically reported setting for HAE attack treatment (54.3% vs 11.6% in 2010 and 32.5% in 2013; P < .001). Physicians reported C1 esterase inhibitor (C1-INH) as the most typically prescribed long-term prophylactic treatment (LTP) (60.0% vs 20.4% in 2010 and 56.7% in 2013; P < .001). Subcutaneous LTP medications were most typically prescribed over intravenous (C1-INH, 41.4%; subcutaneous lanadelumab, 21%; intravenous C1-INH, 18.6%). Danazol, the most frequently prescribed LTP treatment, dropped to 6.4% (55.8% in 2010 and 23.4% in 2013; P < .001). The strongest nonefficacy factor influencing clinician treatment choice changed over time, with cost and (or) insurance coverage increasing to 43.7% (from 24.4% in 2010 and 40.5% in 2013; P = .001), whereas the concern over adverse effects dropped to 16.2% (from 55.8% in 2010 and 29.5% in 2013; P < .001). Physician-reported patient satisfaction remains high, with only 1.5% of physicians indicating patients are not satisfied with treatment. CONCLUSION The US physician survey data reflect improvements in the HAE management in recent years. Therapeutic advances in HAE have led to reported higher rates of home treatment of HAE attacks, reduced concern for adverse treatment effects, and high levels of patient satisfaction.

Clinical features of genetically characterized types of hereditary angioedema with normal C1 inhibitor: a systematic review of qualitative evidence. Orphanet J Rare Dis 2020; 15:289. [PMID: 33059692 PMCID: PMC7559394 DOI: 10.1186/s13023-020-01570-x] [Citation(s) in RCA: 55] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Accepted: 10/05/2020] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Hereditary angioedema (HAE) with normal C1 inhibitor (C1-INH) (HAEnCI) is associated with skin swellings, abdominal attacks, and the risk of asphyxia due to upper airway obstruction. Several different gene mutations linked to the HAE phenotype have been identified. Our aim was to qualitatively assess and describe the clinical differentiators of these genetically identified HAEnCI types. To achieve this, we performed a systematic literature review of patients with angioedema symptoms and a genetically confirmed diagnosis of an HAEnCI type. RESULTS A systematic literature search, conducted in March 2020, returned 132 records, 43 of which describe patients with symptoms of angioedema and a genetically confirmed diagnosis of an HAEnCI type. Overall, this included 602 patient cases from 220 families. HAEnCI with a mutation in the coagulation factor XII gene (F12) (HAE-FXII) was diagnosed in 446 patients from 185 families (male:female ratio = 1:10). Estrogens (oral contraceptives, hormonal replacement therapy, and pregnancy) negatively impacted the course of disease in most female patients (252 of 277). Asphyxia occurred in 2 of 446 patients. On-demand and/or long-term prophylaxis treatment included C1-INH concentrates, icatibant, progestins, and tranexamic acid. HAEnCI with a specific mutation in the plasminogen gene (HAE-PLG) was diagnosed in 146 patients from 33 families (male:female ratio = 1:3). Estrogens had a negative influence on the course of disease in the minority of female patients (14 of 62). Tongue swelling was an important clinical feature. Asphyxia occurred in 3 of 146 patients. On-demand treatment with icatibant and C1-INH concentrate and long-term prophylaxis with progestins and tranexamic acid were effective. HAEnCI with a specific mutation in the angiopoietin-1 gene (HAE-ANGPT1) was diagnosed in 4 patients from 1 family and HAEnCI with a specific mutation in the kininogen-1 gene (HAE-KNG1) in 6 patients from 1 family. CONCLUSIONS A number of clinical differentiators for the different types of HAEnCI have been identified which may support clinicians to narrow down the correct diagnosis of HAEnCI prior to genetic testing and thereby guide appropriate treatment and management decisions. However, confirmation of the causative gene mutation by genetic testing will always be required.

Abstract
Bradykinin (BK)-mediated angioedema (AE) states are rare acquired or hereditary conditions involving localized edema of the subcutaneous and submucosal tissues. Citrated plasma from healthy volunteers or patients with hereditary angioedema (HAE) with normal level of C1-inhibitor (C1-INH) was used to investigate pathways of BK formation and breakdown relevant to AE physiopathology. The half-life of BK (100 nM) added to normal plasma was 34 s, a value that was increased ~12-fold when the angiotensin converting enzyme (ACE) inhibitor enalaprilat (130 nM) was added (enzyme immunoassay measurements). The BK half-life was similarly increased ~5-fold following 2 daily oral doses of enalapril maleate in healthy volunteers, finding of possible relevance for the most common form of drug-associated AE. We also addressed the kinetics of immunoreactive BK (iBK) formation and decline, spontaneous or under three standardized stimuli: tissue kallikrein (KLK-1), the particulate material Kontact-APTT™ and tissue plasminogen activator (tPA). Relative to controls, iBK production was rapid (10–20 min) and very intense in response to tPA in plasma of female heterozygotes for variants in gene F12 coding for factor XII (FXII) (p.Thr328Lys, 9 patients; p.Thr328Arg, one). An increased response to Kontact-APTT™ and an early tPA-induced cleavage of anomalous FXII (immunoblots) were also observed. Biotechnological inhibitors showed that the early response to tPA was dependent on plasmin, FXIIa and plasma kallikrein. Results from post-menopausal and pre-menopausal women with HAE-FXII were indistinguishable. The iBK production profiles in seven patients with the plasminogen p.Lys330Glu variant (HAE-PLG) did not significantly differ from those of controls, except for an unexpected, rapid and lanadelumab-resistant potentiation of KLK-1 effect. This enzyme did not cleave plasminogen or factor XII, suggesting a possible idiosyncratic interaction of the plasminogen pathogenic variant with KLK-1 activity. KLK-1 abounds in salivary glands and human saliva, hypothetically correlating with the clinical presentation of HAE-PLG that includes the swelling of the tongue, lips and contiguous throat tissues. Samples from HAE patients with normal C1-INH levels and F12 gene did not produce excessive iBK in response to stimuli. The ex vivo approach provides physiopathological insight into AE states and supports the heterogeneous physiopathology of HAE with normal C1-INH.

Abstract
Introduction: The hereditary angioedema of type II (HAE type II) is a disease which, in the case of invasive acts such as dental extractions, can trigger potentially fatal laryngeal edema. Observation: A 64-year-old man presented to the hospital to perform dental extractions. The anamnesis revealed a history of hereditary angioedema of type II. The National Reference Center for Angioedema (CREAK) recommended a prophylactic protocol before performing this traumatic dental procedure in order to reduce the risk of post-operative edema. Discussion: The HAE type II is under- or misdiagnosed. The literature reports cases of death related to dental procedures in patients unaware of being a carrier of the disease. Conclusion: In case of certain evocative signs (recurrent edema, abdominal pain, family history, etc.), the odontologist must play an active role in the early detection of HAE type II.

Abstract
Background Hereditary angioedema (HAE) in patients with normal C1 inhibitor (C1-INH) and the c.988A > G (p.Lys330Glu; p.K330E) variant in the plasminogen gene (HAE-PLG) is associated with skin swellings, abdominal pain attacks, and the risk of asphyxiation due to upper airway obstruction. Aim of this observational, retrospective study is to report about the efficacy of various treatments for acute attacks and long-term prophylaxis. Results The study included 111 patients with HAE-PLG. Thirteen patients were treated with icatibant for 201 acute swelling attacks. The mean duration of the treated attacks (mean 4.3 h; standard deviation [SD] 2.6 h) was significantly shorter than that of the previous 149 untreated attacks (mean 44.7 h; SD 28.6 h, p < 0.0001). Twelve patients were treated with plasma-derived C1-INH for 74 acute swelling attacks. The duration of the treated attacks (mean 31.5 h; SD 18.6 h) was significantly shorter than that of the previous 129 untreated in the same patients (mean 48.2 h; SD 32.5 h, p < 0.0001). Corticosteroids alone showed good response in 61/268 attacks (8 patients), low response in 82/268 attacks (7 patients), and no response in 125/268 attacks (26 patients). Corticosteroids combined with antihistamines showed good response in 13/309 attacks (4 patients), low response in 150/309 attacks (7 patients), and no response in 146/309 attacks (17 patients). Antihistamines alone were ineffective in all 37 attacks of 5 patients. In 2 patients with imminent asphyxiation due to tongue swelling and partial obstruction of the upper airways fresh frozen plasma was used without clinical response. The mean reduction in attack frequency was 46.3% under progestins (6 patients), 93.9% under tranexamic acid (3 patients) and 83.3% under danazol (3 patients). Conclusions For patients with HAE-PLG various treatment options are available, which completely or at least partially reduce attack duration or attack frequency.
