Haemophilia and ageing

Advances in the development of effective and safe treatments for haemophilia over the last 50 years have resulted in a significant increase in the life expectancy of persons with haemophilia (PWH). The management of this new cohort of middle‐aged and elderly PWH is challenging because of the opposing risks of haemophilia and age‐related cardiovascular disease and malignancy. Furthermore, this cohort of ageing PWH has the additional comorbidities of human immunodeficiency virus/hepatitis C and chronic haemophilic arthropathy. This article reviews the prevalence, underlying mechanisms and treatment strategies for managing these comorbidities. International collaboration is essential for registry data and further prospective trials to inform optimal evidence‐based management for this rare disorder in the future

Loss of C2orf69 defines a fatal autoinflammatory syndrome in humans and zebrafish that evokes a glycogen-storage-associated mitochondriopathy

Summary Human C2orf69 is an evolutionarily conserved gene whose function is unknown. Here, we report eight unrelated families from which 20 children presented with a fatal syndrome consisting of severe autoinflammation and progredient leukoencephalopathy with recurrent seizures; 12 of these subjects, whose DNA was available, segregated homozygous loss-of-function C2orf69 variants. C2ORF69 bears homology to esterase enzymes, and orthologs can be found in most eukaryotic genomes, including that of unicellular phytoplankton. We found that endogenous C2ORF69 (1) is loosely bound to mitochondria, (2) affects mitochondrial membrane potential and oxidative respiration in cultured neurons, and (3) controls the levels of the glycogen branching enzyme 1 (GBE1) consistent with a glycogen-storage-associated mitochondriopathy. We show that CRISPR-Cas9-mediated inactivation of zebrafish C2orf69 results in lethality by 8 months of age due to spontaneous epileptic seizures, which is preceded by persistent brain inflammation. Collectively, our results delineate an autoinflammatory Mendelian disorder of C2orf69 deficiency that disrupts the development/homeostasis of the immune and central nervous systems

Epidemiology and analysis of invasive fungal infections in patients with hematological malignancies: a single-center real-life experience

WOS: 000414976900031PubMed ID: 29151329Background/aim: Invasive fungal infection (IFI) causes morbidity and mortality among patients with hematological malignancies. We evaluated the incidence and treatment characteristics of IFIs between October 2012 and December 2013. Materials and methods: Patients who received chemotherapy or stem cell transplantation were retrospectively evaluated. Fungal infections were classified according to EORTC criteria. Results: Prophylaxis and antifungal therapy were given in 30.5% and 23.6% of 522 chemotherapy courses, respectively. The incidence of proven/probable IFI was 6.7%. The incidence of IFI among patients who received prophylaxis was significantly higher than among those who did not receive it (11.3% vs. 4.6%, P = 0.005). There was no significant difference between patients who received mold-active and no mold-active prophylaxis (P = 0.098). The most common single agent therapy and causative pathogen was liposomal amphotericin B (57.1%) and Aspergillus (n = 5), respectively. IFI-attributable mortality rate was 14.2% in 6 weeks. Conclusion: The IFI incidence and mortality rate were similar to that reported in the literature. The IFI rate was higher in the group using prophylaxis, as this is a high-risk group. Although the IFI rate was not significantly different between groups using prophylaxis, patients should be followed closely for the effective use of posaconazole prophylaxis

Evaluation of bone mineral density and related parameters in patients with haemophilia: a single center cross-sectional study

WOS: 000415652800002Haemophilia has been associated with low bone mineral density (BMD) probably due to some predisposing factors. The aim of this study was to evaluate the relationship between BMD and potential clinical predictors in adult haemophilic patients. Fortynine patients with moderate and severe haemophilia were enrolled. BMD was measured by Dual Energy X-Ray Absorptiometry (DXA) and blood tests were performed for vitamin D, calcium, phosphore, alkaline phosphatase and parathormone levels. Functional Independence Score in Haemophilia (FISH) and Haemophilia Joint Health Score (HJHS) were used to assess musculoskeletal functions. Body mass index (BMI), Hepatitis C virus (HCV)/Human immunodeficiency virus (HIV) seropositivity and smoking status were also recorded. BMD was found lower than expected for reference age in 34.8% of patients of less than 50 years old. In patients older than 50 years, 66.6% of them had osteoporosis and 33.3% of them had normal BMD. FISH score was statistically significant correlated with BMD of total hip (TH) and femur neck (FN) but not with lumbar spine (LS). In eligible patients, there was also a statistically significant correlation between BMD of TH and HJHS. Vitamine D deficiency was common and found in 77.5% of patients, although there was no significant correlation with BMD. Also no correlation was found between BMD and blood tests, HCV/HIV status, BMI and smoking. This study confirmed that patients with haemophilia have an increased prevelance of low BMD even in younger group. Our results showed that there are significant correlations between FISH score and BMD of TH and FN and also between HJHS score and BMD of TH. Thus, using scoring systems may be beneficial as a simple predictors of BMD to reflect the severity of haemophilic arthropathy.Ege University Medical Faculty Research Project SubcommitteeEge University [2014/TIP/032]We acknowledge that this study was supported by Ege University Medical Faculty Research Project Subcommittee (Grant number: 2014/TIP/032)
