    Comparing the quality of life of patients with hemophilia and juvenile idiopathic arthritis in which chronic arthropathy is a common complication

    Introduction: Hemophilia is a genetic disorder in which recurrent joint bleeding causes arthropathy. Inflammation and degeneration play roles in the pathogenesis of hemophilic arthropathy. Patients with juvenile idiopathic arthritis (JIA) experience a similar inflammatory degenerative joint disease. A comparison of different patients with common pathogenetic features may identify unique features helpful in terms of the follow-up. Aim: We compared the quality of life (QoL) of patients with hemophilia and JIA, and healthy controls, using a generic QoL scale, Kidscreen and Disabkids Questionnaires (KINDL). Differences among groups were evaluated in terms of sociodemographic characteristics and clinical parameters affecting the QoL. Methods: We included 33 hemophilia patients, 19 JIA patients, and 32 healthy individuals aged 4 to 18 years. Sociodemographic characteristics (the age, the maternal educational status, the place of residence, the size of the household, the household income, divorced parents) were noted, and the KINDL was administered to all participants. Clinical parameters associated with arthropathy (the functional independence score [FISH], the hemophilia joint health score [HJHS], the arthropathic joint count, and the painful joint count) were documented. Differences in frequencies and medians among the groups were evaluated using the w2, the Mann- Whitney U, and the Kruskal-Wallis tests. Results: All KINDL dimensions were above 50, reflecting "good conditions" in the 2 patient groups. No difference between patients with hemophilia and JIA was evident in terms of the clinical parameters of FISH, the HJHS, or the arthropathic or painful joint counts (P>0.05). Sociodemographically, only the frequency of literate mothers was lower in patients with hemophilia than in those with JIA and healthy controls (P=0.03). Patients with JIA scored more higher on the KINDL dimension of chronic illness than those with hemophilia (P=0.02). The FISH score correlated with the total QoL score in both patients with hemophilia and JIA (r=0.39, P=0.03 and r=0.48, P=0.04, respectively). Conclusions: Although no difference was evident between the patient groups in terms of clinical parameters associated with arthropathy, JIA patients coped better with illness than those with hemophilia. JIA patients had a higher proportion of literate mothers than hemophilia patients; this may affect a patient's ability to cope with issues relating to chronic illness. Implementation of an educational program for mothers of hemophilia patients, during follow-up, may improve the patient's QoL. Also, hemophilia patients should be assisted to improve their QoL in the dimensions of self-esteem and schooling. Lastly, the evaluation of functional disability by FISH in hemophilia patients is important because the FISH score correlated with the total QoL score, as revealed by KINDL. In JIA patients also, functional disabilities caused by arthropathy affected the QoL. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved.

    Identification of the molecular etiology in rare congenital hemolytic anemias using next-generation sequencing with exome-based copy number variant analysis
    (John Wiley and Sons Inc, 2024) Isik E.; Aydinok Y.; Albayrak C.; Durmus B.; Karakas Z.; Orhan M.F.; Sarper N.; Aydın S.; Unal S.; Oymak Y.; Karadas N.; Turedi A.; Albayrak D.; Tayfun F.; Tugcu D.; Karaman S.; Tobu M.; Unal E.; Ozcan A.; Unal S.; Aksu T.; Unuvar A.; Bilici M.; Azik F.; Ay Y.; Gelen S.A.; Zengin E.; Albudak E.; Eker I.; Karakaya T.; Cogulu O.; Ozkinay F.; Atik T.
    Objectives: In congenital hemolytic anemias (CHA), it is not always possible to determine the specific diagnosis by evaluating clinical findings and conventional laboratory tests. The aim of this study is to evaluate the utility of next-generation sequencing (NGS) and clinical-exome-based copy number variant (CNV) analysis in patients with CHA. Methods: One hundred and forty-three CHA cases from 115 unrelated families referred for molecular analysis were enrolled in the study. Molecular analysis was performed using two different clinical exome panels in 130 patients, and whole-exome sequencing in nine patients. Exome-based CNV calling was incorporated into the traditional single-nucleotide variant and small insertion/deletion analysis pipeline for NGS data in 92 cases. In four patients from the same family, the PK Gypsy variant was investigated using long-range polymerase chain reaction. Results: Molecular diagnosis was established in 86% of the study group. The most frequently mutated genes were SPTB (31.7%) and PKLR (28.5%). CNV analysis of 92 cases revealed that three patients had different sizes of large deletions in the SPTB and six patients had a deletion in the PKLR. Conclusions: In this study, NGS provided a high molecular diagnostic rate in cases with rare CHA. Analysis of the CNVs contributed to the diagnostic success. © 2024 John Wiley & Sons A/S.
