Measles-specific antibodies loss after a single dose of MMR vaccine in children with oligo-articular JIA on methotrexate treatment: a single-center case-controlled study.

Novel treatments have revolutionized the care and outcome of patients with juvenile idiopathic arthritis (JIA). Patients with rheumatic diseases are susceptible to infections, including vaccine preventable ones, due to waning immunity, failing immune system and immunosuppressive treatment received. However, data regarding long-term immunological memory and response to specific vaccines are limited.

Diagnosis and Management of a Young Girl With Tumor Necrosis Factor Receptor Associated Periodic Syndrome (TRAPS) Linked to a Novel Mutation.

A nine-year-old girl with a two-month history of fever and generalized malaise, along with intermittent abdominal pain, immigrant myalgia, throat pain, anorexia, and long-standing failure to thrive, was admitted to our department for further investigation and treatment. Detailed medical history revealed recurrent inflammation attacks from a very young age and a heavily burdened family history. Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) was highly suspected.

A National Survey Across Primary Care Pediatricians Regarding Immunization Views and Practices in Children With Rheumatic Diseases.

Methods: Cross-sectional survey conducted with an anonymous questionnaire of 34 items distributed to pediatricians via an online platform. Four hundred questionnaires were sent, and 256 were returned and analyzed using STATA 13. Data collection included demographics, questions on knowledge, perceptions, and opinions, as well as advice given to families.

Molecular and clinical spectrum of four pedigrees of TRAPS in Greece: results from a national referral center.

Objective: Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is a rare autosomal dominantly inherited autoinflammatory disease caused by mutations of the TNFRSF1A gene. To address the association between TNFRSF1A mutations and clinical phenotype, we analyzed four pedigrees of TRAPS patients.

Methods: Four Greek patients with TRAPS-like clinical features were screened for TNFRSF1A mutations by sequencing exons 2, 3 and 4.

Immunogenicity and side-effects of the inactivated hepatitis A vaccine in periodic fever, aphthous stomatitis, pharyngitis, and adenitis patients.

The aim of this study was to compare the immunogenicity and side-effects of hepatitis A virus (HAV) vaccination between periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) patients and healthy controls who have not been previously exposed to HAV. A prospective observational study was carried out of 28 PFAPA patients and 76 controls who received two doses of the vaccine. Immunogenicity was expressed as seroconversion and seroprotection rates; mean HAV-immunoglobulin G concentration was measured at 0, 1, 7 and 18 months.

Immunogenicity and safety of the inactivated hepatitis A vaccine in children with juvenile idiopathic arthritis on methotrexate treatment: a matched case-control study.

Objectives: To describe the immunogenicity and side effects of immunisation against hepatitis A virus (HAV) in JIA patients on methotrexate treatment, who have not been previously exposed to HAV.

Methods: Case-control study performed in JIA patients and healthy controls matched on age and gender. The subjects received two doses of inactivated anti-HAV vaccine (720 mIU/ml) intramuscularly at 0 and 6 months.

Detection of acquired hemoglobinopathy in children with hematological malignancies at disease onset: results form a national referral centre.

Abnormal hemoglobin synthesis is usually inherited but may also arise as a secondary manifestation of a hematological neoplasia. The objective of this study is to identify the presence of acquired hemoglobinopathy in children diagnosed with hematological malignancies and compare these against healthy controls. Prospective matched case-control study held from 2010 to 2012.

Bartonella henselae Infection: An Uncommon Mimicker of Autoimmune Disease.

We present a case of a seven-year-old immunocompetent female patient who developed systemic symptoms mimicking an autoimmune rather than an infectious disease. The patient presented with rash, biquotidian fever, night sweats, and arthralgias. There was no antecedent history of cat contact.
