Use of a central venous access device (CVAD) can facilitate early introduction of home-based infusion of factor concentrate for long-term prophylaxis or immune tolerance therapy in children with bleeding disorders. The aim was to review outcomes associated with use of CVAD. Retrospective review of paediatric patients with bleeding disorders was observed at the Mayo Clinic Comprehensive Hemophilia Center. Thirty-seven CVAD were placed in 18 patients (haemophilia A [n = 15], type 3 von Willebrand disease [n = 2] and haemophilia B [n = 1]). Follow-up was for 45 952 CVAD days, and median time that CVAD remained in place was 1361 days per device. Factor VIII (FVIII) inhibitors were present in 4 of the 15 patients. Ten CVAD-related infections occurred (median, 672 days; range, 72-1941 days), of which six were in one patient with FVIII inhibitors. Overall infection rate was 0.22 (95% confidence interval [CI], 0.10-0.40) per 1000 CVAD days, with 0.11 infections in patients without FVIII inhibitors compared with a pooled incidence of 0.66 (95% CI, 0.44-0.97) reported in the literature. Indications for removal of 27 CVAD were blockage, change to peripheral venous access, catheter displacement, infection, leak in the port septum, short catheter and skin erosion. No clinically apparent thrombosis or sequelae of thrombosis were observed. Infection is the most common complication associated with CVAD use and is increased in patients who have inhibitors. The low rate of clinically apparent thrombosis reflects our practice of not screening for thrombosis. The low infection rate reflects our practice of using and reinforcing the aseptic technique.

Circumcision is one of the most common procedures performed in male neonates, but few published reports have described circumcision in patients with bleeding disorders. The aim of this study was to analyse outcomes of circumcision among children evaluated at our institution to determine the extent of complications and to provide guidelines for circumcision management. We searched our patient database for records of children who were followed up at the Mayo Clinic Comprehensive Hemophilia Center from 2000 through 2007 and who had been circumcised. We retrospectively reviewed the medical records to document complications and determine management strategies in this patient population. Of 55 children and young adults identified (median [range] age, 15 years [11 months to 21 years]), 48 patients were circumcised. Indications for circumcision were parental request (n = 45) and medical recommendation (n = 3). Twelve of 21 patients with a known bleeding disorder at the time of circumcision received factor replacement before the procedure. Three of these 21 patients had bleeding complications. Of the other 27 patients, who were diagnosed later in life as having a bleeding disorder, 8 had bleeding complications. The overall incidence of bleeding after circumcision was 23% (11/48). The 23% overall incidence of bleeding complications in our patients with bleeding disorders is comparable to that reported for patients without a bleeding disorder (0.1-35%). Some of our patients had significant bleeding despite adequate factor replacement before and after the procedure. Parents and patients must be aware that bleeding risk is a possibility despite adequate factor replacement for hemostasis.

BackgroundAutoinflammatory diseases (AIDs) illnesses of the innate immunity resulting in clinical signs and symptoms of systemic inflammation and loss of organ functions. While pathophysiological mechanisms are heavily studied and increasingly well understood, psychosocial needs are much less explored. The disease impact on the everyday life of patients including school and work is poorly studied. The purpose of the study was to identify the spectrum of unmet needs of children, adolescents and adults living with autoinflammatory disease and their families, to define key unmet needs and strategies and to develop and evaluate a pilot intervention addressing the unmet need “school”.MethodsA single-center, mixed-method study of AID patients and their families was conducted. Consecutive patients ages ≥4 years and their families were included. Expert consulting, focus groups and questionnaires explored the patient perspective of “unmet needs in AID”. Quantitative and qualitative content analyses were performed and informed the development of a framework of unmet needs. A targeted pilot multimodular intervention for the unmet need “school” was developed and tested. Health-related Quality of Life (HRQoL) was evaluated using DISABKIDS-questionnaires and psychosocial impact evaluations.ResultsThe study included 83 patients and their families. These were 14 children, 9 adolescents and 25 adults with AID and 35 family members; patients’ median age was 19 years (5–78). Expert consultations: 110 AID patients with 320 visits/year; 99 (90%) were children and adolescents. 78 patients and family members (94%) participated in 10 groups. Qualitative content analysis delineated 9 domains of unmet needs, the most relevant being school, health care system and public institutions. The pilot intervention“school” included 18 participants; median age was 9 years (7–16). HRQoL improved with the intervention including “understanding” by 53%, however improvement was not sustained over time.ConclusionUnmet needs of AID patients and families affect all areas of life. Accessible networks increasing knowledge and empowering patients, strategies supporting academic and workplace environments to ensure successful participation and integrated concepts addressing psychosocial needs are urgently needed.

Congenital factor VII (FVII) deficiency is an autosomal recessive bleeding disorder with variable phenotypic correlation between FVII activity and bleeding risk. We report a novel mutation of the FVII gene that creates the amino acid change Ser 103 to Gly, which resulted in severe FVII deficiency with reduced FVII antigen. This mutation in the heterozygous form was also present in a mildly affected, unrelated patient. We also report on the natural history of an FVII inhibitor in the patient with severe FVII deficiency.
