Objective Kawasaki disease (KD) is an acute systemic vasculitis that is one of the major causes of acquired heart disease especially in young children. The pathogenesis of KD is still unclear. The increased incidence of the disease among Japanese children and siblings of affected patients suggests a genetic component to KD susceptibility. Several reports have studied human leukocyte antigen (HLA) polymorphisms in different populations with KD and found various results. In the present study, we aimed to evaluate the association of HLA-A, -B, -C, -DRB1, and -DQB1 allele frequencies in Turkish children with KD. Methods The study was conducted between January 2016 and February 2018. HLA Class I (A, B, and C) and Class II (DRB1 and DQB1) alleles of patients and healthy controls were studied using the low-resolution DNA-based sequence-specific oligonucleotide method. Results Fifty children with KD and 500 healthy controls were included in this study. In the analysis of HLA-A, HLA-B, HLA-C, and HLA-DRB1 alleles, no statistical difference was found in the frequency of alleles between the patients with KD and the control group. However, a significantly lower frequency of the HLA-DQB1*03 allele was observed in the KD group than in the control group (p < 0.001, odds ratio [OR]: 0.29, 95% confidence interval [CI]: 0.15–0.55). When the patients with KD were divided into two subgroups with or without coronary artery lesions (CALs), the frequency of the HLA-DQB1*03 allele was also found lower in the KD group with CALs than the KD group without CALs (p = 0.008, OR: 0.19, 95% CI: 0.05–0.68). Conclusion The study may guide future studies on HLA-DQB1*03 whether it is a protective allele for KD and CALs in Turkish children. [ABSTRACT FROM AUTHOR]

Background. The prevalence of community-acquired methicillin-resistant S. aureus (CA-MRSA) has been increasing worldwide. We aimed to investigate the prevalence of MRSA in community-acquired S. aureus infections, the risk factors for CA-MRSA infection and the clinical features of CA-MRSA. Methods. A multi-center study with prospective and retrospective sections was conducted. Patients ≥ 3 months old and ≤18 years of age who were diagnosed with community-acquired S. aureus infections were included in this study and the patients' information were reviewed from the medical and microbiological database of the hospital. A standard question form about living conditions and exposure risk factors was administered to the parents of patients. The CA-MRSA infections were compared with the methicillin-susceptible S. aureus (CAMSSA) infections in terms of the queried risk factors and clinical variables. Results. We identified 334 pediatric patients with S. aureus infection, 58 (17.4%) had an infection with CAMRSA. The refugee rate was higher in the CA-MRSA group. There was no significant difference regarding the exposure risk. The treatment modalities and outcomes were similar. Conclusions. The study was not able to show reliable clinical variables or epidemiological risk factors except for being a refugee for CA-MRSA infections. Empirical antibiotic treatment should therefore be determined according to the local CA-MRSA prevalence in patients presenting with a possible staphylococcus infection. [ABSTRACT FROM AUTHOR]

Aim: Kawasaki disease (KD) is difficult to diagnose in infants, since the disease course is subtle. We aimed to identify whether infants with KD demonstrate significant alterations in laboratory parameters that can be used to distinguish them from other febrile infants. Materials and Methods: In this retrospective case-control study, infants diagnosed with KD between January 2010 and December 2019 were evaluated and compared to a cohort of febrile infants admitted with prolonged fever during the same period. Demographic, clinical, and laboratory features were recorded and compared between these two groups. Results: A total of 42 infants (27 male) with KD (32 incomplete KD) and 84 age-matched febrile infants (57 male) were evaluated. Coronary artery involvement was identified in 20 (47.6%) infants of whom 5 (25%) had coronary aneurysms. All infants with KD were treated with IVIG and high dose acetylsalicylic acid, and 38 (90.5%) responded to treatment. The duration of fever and hospitalization were longer in infants with KD compared to the controls (p<0.001). White blood cell (WBC), eosinophil, platelet counts, platelet distribution width, acute phase reactants, alanine aminotransferase, and gamma glutamyl transferase were significantly higher; whereas, mean platelet volume (MPV), hemoglobin, and albumin levels were lower in the KD group compared to the controls. Lower MPV and albumin values were found to be independently associated with a higher likelihood of having a KD diagnosis. Conclusion: It may be difficult to diagnose KD in infants. Our data shows that MPV and albumin may be used as supportive parameters to differentiate KD from other febrile conditions in infants. [ABSTRACT FROM AUTHOR]

Introduction: Human brucellosis is one of the most common zoonotic infections in the world. The definitive diagnosis of brucellosis is based on cultured Brucella organisms from blood or other tissue samples. We aimed to compare bacteremic and nonbacteremic brucellosis patients with demographical, epidemiological, clinical and laboratory features and determine the predictive factors affecting blood culture positivity.Materials and Methods: Children aged 1 month to 18 years who were followed up with the diagnosis of brucellosis between January 2005 and March 2021 were included in this retrospective study. According to the isolation of Brucella melitensis in blood culture, the patients were divided into two groups as bacteremic and nonbacteremic and compared in terms of demographic, clinical and laboratory characteristics.Results: One hundred eighty-nine (116 male, 61.4%) patients diagnosed with brucellosis were included in the study. There were 76 (40.2%) bacteremic and 113 (59.8%) nonbacteremic patients. Bacteremic patients were younger than nonbacteremic patients. Fever, arthralgia, hepatomegaly and splenomegaly were significantly higher in the culture positive group. High levels of C-reactive protein (CRP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were found to be significant in the bacteremic group.Conclusion: In our study, history of fever and arthralgia, hepatomegaly and splenomegaly in physical examination and high CRP, ALT and AST levels in the biochemical analysis were important factors determining blood culture positivity.

Systemic onset juvenile idiopathic arthritis is the most chronic rheumatologic disease of childhood. Diagnostic criteria includes arthritis and intermittent fever which continues at least two weeks, accompanying with one of the following: pale erithematous macular rash, generalized lymphadenopathy, hepatosyplenomegaly or serositis. Complications of systemic juvenile idiopathic arthritis are osteopenia, osteoporosis, growth retardation, erosive arthritis, amiloidosis and potentially fatal macrophage activation syndrome. In some cases, the macrophage activation syndrome may be simultaneous with the diagnosis of the disease and early recognition and treatment is life-saving. Here, a 2.5-year-old girl who presented with systemic juvenile idiopathic arthritis and signs of macrophage activation syndrome was presented to emphasize the importance of early diagnosis and treatment.

Kawasaki disease (KD) is a generalized systemic vasculitis predominantly involving medium-sized arteries. The Kawasaki disease shock syndrome (KDSS) was reported firstly as myocardial dysfunction, earlier onset, coronary artery involvement, and poor response to standard intravenous immunoglubulin (IVIG) therapy. A three-month-old girl was admitted with high fever, irritability, poor feeding and hemodynamic instability. For the presence of pyuria, fever and clinical sepsis suspicion, intravenous empirical antibiotic treatment was commenced with a preliminary diagnosis of urosepsis. Thereafter, an echocardiographic investigation was performed because of persistent fever and increasing platelet counts. Kawasaki disease was diagnosed by determining coronary artery dilation on echocardiography. Here, a young infant with KDSS was reported to emphasise this uncommon presentation of Kawasaki disease, because of possible fatal outcome without timely IVIG treatment. [ABSTRACT FROM AUTHOR]

Background: Brucellosis is a multisystem disease that may present with a broad spectrum of clinical manifestations and complications. Neurobrucellosis is an uncommon and serious complication of pediatric brucellosis., Methods: We describe seven cases of neurobrucellosis., Results: Ataxia (one patient), diplopia (one patient) and hearing loss (one patient) were among the neurological signs and symptoms. The most common diagnoses were acute meningitis and meningoencephalitis. Five of the patients fully recovered, one was lost to follow up and the other had hearing loss as a sequela., Conclusion: Neurobrucellosis should be kept in mind in patients with any neurological or neuropsychiatric diseases who live in endemic areas of brucellosis., (© 2014 Japan Pediatric Society.)
