6% female) healthy, normal subjects aged 2–69 years. Female subjects had greater joint mobility in all age groups in nearly all joints and the gender difference was most obvious in measures of ankle plantarflexion, elbow pronation and supination. Range of motion average values for all joints decreased with advancing age for both men and women and, in most cases, were significantly different than most commonly used normative
values. Our study of ROM measurements taken by trained physical therapists on a large Natural Product Library supplier sample of healthy individuals revealed significant gender- and age-related variation that may be an important consideration in patient assessment. “
“Summary. Acquired haemophilia A (AH) is a rare bleeding disorder caused by an auto-antibody to coagulation factor VIII. It is associated with various autoimmune diseases, pregnancy, cancer or drug ingestion; however, in 50% of patients, no underlying disorder is found. In the present study, we investigated the association of HLA class I (A, B and Cw) and class II (DRB1 and DQB1) alleles with AH in a cohort of
57 patients. While no association with any class I allele was detected, a significantly higher frequency of DRB1*16 [odds ratio (OR) 10.2, 95%CI: 5.32–19.57, P < 0.0001] and DQB1*0502 (OR 2.2, 95%CI: 1.12–4.54, P < 0.05) was observed. In contrast, the frequency of DRB1*15 and DQB1*0602 alleles was found to be decreased in patients with AH corresponding to an OR of 0.4 for both HLA loci. Upon comparing the frequencies of these alleles with those of patients with congenital haemophilia A with inhibitors, the data demonstrate that the high click here risk alleles in patients with AH DRB1*16 and DQB1*0502 are found to be low risk alleles in patients with congenital haemophilia A with inhibitors (OR 1.1 and 1.5 respectively). Conversely, the alleles that exhibit low risk in AH DRB1*15 and DQB1*0602 are found to be high risk for haemophilia A inhibitor patients (OR 2.2 and 3.7 respectively). The pathophysiological reason for this finding remains unknown. It might be speculated that the presence or absence of the FVIII antigen Farnesyltransferase and the various ability of HLA molecules
to present the FVIII antigen to the T-cell receptor contribute to these findings. Acquired haemophilia (AH) is a rare autoimmune bleeding disorder (incidence 0.2–1 per million) caused by autoantibodies to factor VIII. It is characterized by sudden, usually severe onset of bleeding in patients with no family or personal history of bleeding diatheses [1–4]. Approximately 50% of the patients are classified as idiopathic as no underlying disease can be detected [5,6]. However, AH has been reported to be associated with underlying malignancies, postpartum period, drug administration or autoimmune diseases such as rheumatoid arthritis or systemic lupus erythematosus [7–9]. The aetiology of the disease is still unknown, at least in part, because of its low frequency.
