[Role of Hematological Parameters in the Diagnosis of Juvenile Idiopathic Arthritis in Children with Arthritis].

Andes Pediatr 2022 Apr;93(2):229-234

Health Sciences University, Izmir, Turkey.

Introduction: Early diagnosis and treatment of arthritis are essential for the prognosis of the disease. Especially during the active phase of juvenile idiopathic arthritis (JIA), a prompt diagnosis is necessary to ma nage the disease properly. New inflammation markers such as neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), mean platelet volume (MPV), and platelet distribution width (PDW) have been investigated in various inflammatory disorders.

Temporomandibular Joint Acoustic Emissions in Children With Juvenile Idiopathic Arthritis Differ From Those in Healthy Children.

J Oral Maxillofac Surg 2022 Jun 7. Epub 2022 Jun 7.

Associate Professor of Surgery, Division of Oral and Maxillofacial Surgery, Department of Surgery, Emory University School of Medicine, Chief, Oral and Maxillofacial Surgery, Children's Healthcare of Atlanta. Electronic address:

Purpose: Articulation of the temporomandibular joint (TMJ) generates sounds with specific characteristics known as joint acoustic emissions (AEs). The purpose of this project was to determine if AEs as described by the joint health score (JHS) in children with juvenile idiopathic arthritis (JIA) differ from AEs in healthy children.

Patients And Methods: The investigators implemented a cross-sectional study with age- and sex-matched controls to compare AEs from 4 groups: (1) healthy subjects without TMJ sounds, (2) healthy subjects with TMJ sounds, (3) subjects with JIA without TMJ sounds, and (4) subjects with TMJ sounds.

New Insights on Juvenile Psoriatic Arthritis.

Front Pediatr 2022 26;10:884727. Epub 2022 May 26.

Department of Woman's and Child's Health, University of Padova, Padova, Italy.

Juvenile psoriatic arthritis (JPsA) is a relatively rare condition in childhood as it represents approximately 5% of the whole Juvenile Idiopathic Arthritis (JIA) population. According to International League of Associations of Rheumatology (ILAR) classification, JPsA is defined by the association of arthritis and psoriasis or, in the absence of typical psoriatic lesions, with at least two of the following: dactylitis, nail pitting, onycholysis or family history of psoriasis in a first-degree relative. However, recent studies have shown that this classification system could conceal more homogeneous subgroups of patients differing by age of onset, clinical characteristics and prognosis. Read More

Quality improvement in juvenile idiopathic arthritis: a mixed-methods implementation pilot of the CAPTURE-JIA dataset.

Pediatr Rheumatol Online J 2022 Jun 18;20(1):43. Epub 2022 Jun 18.

Department of Rheumatology, Alder Hey Children's Hospital, Liverpool, UK.

Background: A significant proportion of children and young people with juvenile idiopathic arthritis (JIA) do not achieve inactive disease during the first two years following diagnosis. Refinements to clinical care pathways have the potential to improve clinical outcomes but a lack of consistent and contemporaneous clinical data presently precludes standard setting and implementation of meaningful quality improvement programmes. This study was the first to pilot clinical data collection and analysis using the CAPTURE-JIA dataset, and to explore patient and clinician-reported feasibility and acceptability data. Read More

Hyaluronidase 1 deficiency decreases bone mineral density in mice.

Sci Rep 2022 Jun 16;12(1):10142. Epub 2022 Jun 16.

URPhyM, Intracellular Trafficking Biology, NARILIS, University of Namur, Rue de Bruxelles 61, 5000, Namur, Belgium.

Mucopolysaccharidosis IX is a lysosomal storage disorder caused by a deficiency in HYAL1, an enzyme that degrades hyaluronic acid at acidic pH. This disease causes juvenile arthritis in humans and osteoarthritis in the Hyal1 knockout mouse model. Our past research revealed that HYAL1 is strikingly upregulated (~ 25x) upon differentiation of bone marrow monocytes into osteoclasts. Read More

Psychological tendencies of children with juvenile idiopathic arthritis.

Scand J Psychol 2022 Jun 10. Epub 2022 Jun 10.

School of Psychological Sciences, Tel-Aviv University, Tel Aviv, Israel.

A bulk of studies showed an association between stressful events and juvenile idiopathic arthritis (JIA) but failed to identify specific psychological tendencies that contribute to the patients' vulnerability to stress. The purpose of this paper is to identify psychological tendencies specific to JIA that would unravel characteristic sources of stress. The study is based on the cognitive orientation model of health, which enables us to identify these kinds of tendencies in terms of four belief types (beliefs about self, general beliefs, beliefs about norms, and goals) that refer to specific themes.

Mass Switch From Intravenous to Subcutaneous Tocilizumab in Rheumatic Diseases During the SARS-COV-2 Pandemic.

J Clin Rheumatol 2022 Jun 3. Epub 2022 Jun 3.

From the Servicio de Reumatología, Hospital Universitario de Navarra.

Background: With the arrival of the SARS-CoV-2 pandemic in 2020, it was proposed to make the change from intravenous (IV) tocilizumab (TCZ) to its subcutaneous formulation, in order to avoid rheumatological patients having to go to the day hospital and guarantee enough IV TCZ for those critical patients with COVID who needed it. The aim of this study was to describe the rate and reasons for switching back to IV TCZ from subcutaneous TCZ.

Methods: We included patients from the rheumatology service that were on treatment with IV TCZ in February 2020 and were followed up until March 2021. Read More
