Objetivo: Avaliar as características clínicas e laboratoriais para diferenciar leucemia linfoblástica aguda (LLA) da artrite idiopática juvenil forma sistêmica (AIJs) no início da doença. Métodos: Cinquenta e sete pacientes com LLA com envolvimento musculoesquelético, sem blastos no sangue periférico e sem terapia com glucocorticoide no início da doença e 102 pacientes com AIJs (critérios ILAR) foram retrospectivamente avaliados. Foram estudadas as seguintes características: febre, exantema reumatoide, artrite, dor em membros, hepatomegalia, esplenomegalia, pericardite, miocardite, pleurite, perda de peso, sangramento, anemia, leucopenia, neutropenia, plaquetopenia, níveis séricos elevados de velocidade de hemossedimentação (VHS) e de desidrogenase lática (DHL). Resultados: A mediana da idade de início da doença foi significativamente maior em pacientes com LLA comparada com AIJs (5,8 vs. 3,8 anos, p=0,0006). As frequências de dor em membros, hepatomegalia, perda de peso e manifestações hemorrágicas foram significativamente maiores em LLA versus AIJs (70% vs. 1%, p<0,0001; 54% vs. 32%, p=0,0075; 30% vs. 8%, p=0,0005; 98% vs. 0%, p=0,0053; respectivamente). Igualmente, as frequências de anemia, leucopenia, neutropenia, plaquetopenia e DHL elevado foram significativamente maiores em LLA versus AIJs (88% vs. 57%, p<0,0001; 39% vs. 1%, p<0,0001; 60% vs. 1%, p<0,0001; 77% vs. 1%, p<0,0001; 56% vs. 14%, p<0,0001; respectivamente). Consideravelmente, a análise multivariada mostrou que dor em membros (OR=553; 95% IC=46,48-6580,42; p<0,0001) e plaquetopenia (OR=754,13; 95% IC=64,57-8806,72; p<0,0001) permaneceram como variáveis independentes que diferenciaram pacientes com LLA de pacientes com AIJs. O R2 de Nagelkerke foi de 0,91. A curva de sobrevida de Kaplan-Meier foi similar em pacientes com LLA com e sem dor em membros (p=0,8347). Conclusão: O presente estudo enfatiza a importância de investigar pacientes com LLA que apresentam manifestações musculoesqueléticas, particularmente dor em membros com plaquetopenia / Objective: To assess clinical and laboratorial features which differentiate acute lymphoblastic leukemia (ALL) from systemic onset juvenile idiopathic arthritis (SoJIA) at disease onset. Methods: Fifty seven ALL patients with musculoskeletal involvement, without blasts on peripheral blood and glucocorticoid therapy at onset of disease and 102 SoJIA patients (ILAR criteria) were retrospectively evaluated. The following features were studied: fever, rheumatoid rash, arthritis, limb pain, hepatomegaly, splenomegaly, pericarditis, myocarditis, pleuritis, weight loss, bleeding, anemia, leukopenia, neutropenia, thrombocytopenia, high erythrocyte sedimentation rate and high lactic dehydrogenase (LDH) levels. Results: The median age at disease onset was significantly higher in ALL compared to SoJIA patients (5.8 vs. 3.8years, p=0.0006). The frequencies of limb pain, hepatomegaly, weight loss and hemorrhagic manifestations were significantly higher in ALL versus SoJIA patients (70% vs. 1%, p<0.0001; 54% vs. 32%, p=0.0075; 30% vs. 8%, p=0.0005; 98% vs. 0%, p=0.0053; respectively). Likewise, the frequencies of anemia, leukopenia, neutropenia, thrombocytopenia and high LDH levels were significantly higher in ALL versus SoJIA patients (88% vs. 57%, p<0.0001; 39% vs. 1%, p<0.0001; 60% vs. 1%, p<0.0001; 77% vs. 1%, p<0.0001; 56% vs. 14%, p<0.0001; respectively). Remarkably, multivariate analysis showed that limb pain (OR=553; 95% CI=46.48-6580.42; p<0.0001) and thrombocytopenia (OR=754.13; 95% CI=64.57-8806.72; p<0.0001) remained as independent variables that differentiate ALL from SoJIA patients. The R2 of Nagelkerke was 0.91. The Kaplan-Meier survival curves were similar in ALL patients with and without limb pain (p=0.8347). Conclusion: The present study emphasizes the importance to investigate ALL patients who have musculoskeletal manifestations, particularly limb pain associated with thrombocytopenia

Background: The aim of this cross-sectional study was to investigate oral health and functional status of adolescents with juvenile idiopathic arthritis (JIA) and its possible link to disease specific parameters. Methods: Patients with JIA were recruited (November 2012–October 2014) and disease specific information was extracted from patients’ records. Oral examination included: dental findings (decayed-, missing- and filled-teeth-index (dmf-t/DMF-T)), gingival inflammation (papilla-bleeding-index (PBI)) and periodontal screening index (PSI). Functional examination followed Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Additionally, modified Helkimo’s Clinical Dysfunction Index and radiographic scoring were recorded. Results: 59 JIA patients were included. The mean dmf-t/DMF-T was 2.6. Only one patient showed no signs of gingival inflammation, while 57.6% had a maximum PSI of 2 or less. Positive functional findings were assessed clinically in more than half of the patients. Major diagnosis by RDC/TMD was osteoarthrosis. Patients with at least one positive anamnestic or clinical functional finding revealed significantly higher radiographic scores (CI = 0.440, p = 0.022). Patients with increased c-reactive-protein had a significantly higher PBI (Z = –2.118, p = 0.034) and increased radiographic scores (CI = 0.408, p = 0.043). Conclusions: Adolescents suffering from JIA show high levels of caries experience and gingival inflammation. Temporomandibular joint dysfunction is often seen in JIA patients. Consequently, special dental care programs would be recommendable.

Rates of immune-mediated diseases (IMDs) have rapidly increased. Although the exact etiology has not yet been fully elucidated, disruptions to the microbiome has been proposed as a potential mechanism. We conducted a retrospective, longitudinal, birth cohort study utilizing electronic health records (EHR) to investigate the association between early life antibiotic exposure and the risk of developing juvenile idiopathic arthritis (JIA), pediatric psoriasis, or type 1 diabetes. Incident rate ratios (IRR) were estimated using modified Poisson regression models and adjusted for significant confounders. Children exposed to two or more antibiotics prior to 12 months of age had a 69% increased risk of developing JIA (1.69 IRR, 95% CI [1.04-2.73]), which rose to 97% when exposed prior to 6 months (1.97 IRR, 95% CI [1.11-3.49]). Children exposed to a penicillin antibiotic had a 62% increase in risk for psoriasis (1.62 IRR, 95% CI [1.06-2.49]), which rose slightly to 64% when exposure occurred between 6 and 12 months of age [(1.64 IRR, 95% CI [1.04-2.59]). We found a moderate to strong association between early antibiotic exposure and risk for JIA and psoriasis when exposure was examined by age, frequency, and type of antibiotic, but not for type 1 diabetes. Potential interactions effects between infection and antibiotics with an increased susceptibility to early life infections among children with an IMD was also observed. Overall, children exposed to antibiotics at an early age have an increased probability of developing an IMD after 12 months of age. However, alternative explanations for this association should be considered. / Public Health

Background and aim: As an experienced paediatric nurse I have recognised that adolescents with persistent chronic childhood diseases fall between two chairs. International studies support this recognition. Norwegian adolescents with juvenile idiopathic arthritis are no exception. Chronic arthritis from childhood might have far-reaching consequences for the growth and development of the child, and for the family and community. The fact that a considerable proportion of children with JIA continue to have active disease and disease residua through adolescence into adulthood underlines the importance of illuminating the situation in a public-health perspective. Through this study I aim at exploring physical and psychosocial health among young adults with JIA in a life-span perspective from childhood and adolescence into adult life. Methods: The thesis has a qualitative and a quantitative approach. Study I had an abductive explorative design. The experiences and perceptions of health-care transition were explored by focus-group interviews with young people with JIA and related health professionals respectively. Qualitative content analysis was utilised. Study II had an abductive explorative design with qualitative interviews to explore young adults’ experiences of living with JIA in a life-span perspective. Qualitative content analysis was utilised. Study III had a longitudinal deductive design. The standardised questionnaires of Health Assessment Questionnaire, General Health Questionnaire version 30, and Visual Analogue Scales of pain, fatigue, and illness were utilised to explore physical ability, psychosocial health, pain, fatigue, and illness in a cohort of patients with JIA 18.3 years after symptom-onset. Comparisons with baseline and first follow-up were performed. Data were analysed by descriptive statistics and non parametric tests. Study IV had a cross-sectional deductive design. In addition to the questionnaires utilised in study III, the questionnaire of SF-36 Health Survey and data on education, employment, need of assistive equipment at work, and use of health services the previous year were employed. Comparisons with Norwegian population- based data were performed. Data were analysed by descriptive statistics, and parametric and non parametric tests. Findings: In study I, ability to live a meaningful and responsible adult life seemed to be a common goal. Obstacles for the young people were the nature of the disease, a lack of focus on transition processes, and overprotective parents and health professionals. Obstacles for the health professionals were lack of inter-professional and inter-institutional formal co-operation and agreed practice, and lack of competence on adolescent development and health. Study II demonstrates that living with JIA implies a constant oscillation between struggle and adjustment to an insecure everyday life and an unpredictable life course. This was expressed as bodily experiences of limitation and freedom, interpersonal experiences of being included or set on the sidelines, and intrapersonal perceptions of insecurity and confidence. Of the 55 young adults with JIA in study III, 21 reported physical disability, and 12 reported psychiatric distress within the clinical range. Furthermore, 26 patients reported illness, 27 pain, and 33 fatigue above 10 on the VAS scale (0-100). Significant correlations were found between physical disability, pain, illness and fatigue, and between psychiatric distress, pain, and fatigue. Comparisons from first to second follow-up of the cohort showed no significant changes in physical or psychosocial functioning, pain, or fatigue. In study IV, physical ability and pain were significant predictors of the average variation of physical health while psychiatric distress and female gender were significant predictors of the average variation of mental health. Impaired physical health was associated with low rates of psychiatric distress. As compared to the general Norwegian population, impaired HRQL in the physical domain was found, but not in the mental domain, and a higher level of education, but similar employment rate. Conclusion: The four studies demonstrate complementary findings. Discrepancies between interviews and inquiries indicate that the interviews illuminate a depth and breadth of life with JIA in a life-span perspective that not is possible to unveil solely by standardised inquiries. Although persistent favourable outcomes are found physically and psychosocially from first to second follow-up, young adults with JIA reveal that life with JIA encompasses struggle and adjustment to an insecure life situation physically, psychologically, and socially. / Bakgrunn og mål: Mange års erfaring som pediatrisk sykepleier har vist meg at unge mennesker med kroniske barnesykdommer faller mellom to stoler i overgangen til voksent liv. Internasjonale studier støtter denne erfaringen, og norske ungdommer med juvenil idiopatisk artritt er ikke noe unntak. Kronisk barneleddgikt kan ha vidtrekkende konsekvenser for barnets vekst og utvikling, for familien og samfunnet for øvrig. Det faktum at mange barn fortsetter å ha aktiv sykdom og senvirkninger av sykdommen gjennom ungdomsårene og inn i voksent liv, understreker betydningen av å belyse de unges helse og livssituasjon i et folkehelseperspektiv. Gjennom denne avhandlingen ønsker jeg å undersøke fysisk, psykisk og sosial helse blant unge voksne med barneleddgikt i et livsløpsperspektiv. Metode: Avhandlingen har en kvantitativ og en kvalitativ tilnærming. Studie I hadde en abduktiv eksplorerende design. Gjennom fokusgruppeintervjuer med respektivt unge mennesker med barneleddgikt og helsepersonell innen revmatologi ble opplevelser og erfaringer med overgangen til voksenhelsetjenesten undersøkt. Kvalitativ innholdsanalyse ble benyttet. Studie II hadde også en abduktiv eksplorerende design med kvalitative intervjuer for å utforske livet med barneleddgikt blant unge voksne i et livsløpsperspektiv. Kvalitativ innholdsanalyse ble benyttet også her. Studie III hadde en longitudinell deduktiv design. Standardiserte spørreskjemaer om fysisk funksjon (Health Assessment Questionnaire), psykososial helse (General Health Questionnaire versjon 30), og sykdomsfølelse, smerte og trøtthet (Visual Analogue Scales) ble anvendt for å undersøke selvvurdert helse blant kohorten 18.3 år etter symptomdebut. Sammenligning med baselinestudien og første oppfølging ble gjort. Deskriptiv statistikk og non parametriske tester ble benyttet i dataanalysen. Studie IV var en deduktiv tverrsnittsstudie. I tillegg til spørreskjemaene som ble benyttet i studie III, ble spørreskjemaet SF-36 Health Survey benyttet for å undersøke selvvurdert helserelatert livskvalitet. Data fra telefonintervjuet om utdanning, yrkesaktivitet, behov for hjelpemidler på jobb, og behov for helsetjenester siste året ble inkludert. Sammenligninger ble gjort med norske normdata. Deskriptiv statistikk, parametriske og non parametriske tester ble benyttet i dataanalysen. Funn: Studie I viste at det å være i stand til å leve et meningsfylt og ansvarsbevisst voksenliv var et felles mål. Hindringer for de unge viste seg å være sykdommens natur, manglende fokus på overgangsprosessen, og overbeskyttende foreldre og helsepersonell. Hindringer blant helsepersonell var mangel på formelt samarbeid og omforent praksis på tvers av profesjoner og institusjoner, og mangel på kompetanse om ungdoms helse og utvikling. Studie II viste at livet med barneleddgikt innebærer en konstant veksling mellom kamp og tilpasning til et usikkert dagligliv og et uforutsigbart livsløp. Dette kom til uttrykk i erfaringer om kroppslige begrensninger eller frihet, interpersonlige opplevelser av å bli inkludert eller satt til side, og intrapersonlige opplevelser av usikkerhet eller trygghet. Blant de 55 unge voksne med barneleddgikt i studie III rapporterte 21 fysiske funksjonshemninger og 12 psykiatrisk distress. Videre rapporterte 26 pasienter sykdomsfølelse, 27 smerter, og 33 trøtthet med en skåring på 10 eller mer på VAS-skalaene (0-100). Signifikante korrelasjoner ble funnet mellom fysisk funksjonshemning, smerter, sykdomsfølelse og trøtthet, og mellom psykiatrisk distress, smerter og trøtthet. Sammenligninger fra første til andre oppfølging av kohorten viste ingen signifikante endringer i fysisk eller psykisk funksjonsevne, smerter eller trøtthet. Studie IV viste at fysisk funksjons-hemning og smerter var signifikante prediktorer for den gjennomsnittlige variasjonen i fysisk helse, mens psykiatrisk distress og kvinnelig kjønn var signifikante prediktorer for den gjennomsnittlige variasjonen i mental helse. Sviktende fysisk helse var ikke assosiert med psykiatrisk distress. Sammenlignet med norske normdata fant vi sviktende helserelatert livskvalitet i det fysiske domene, men ikke i det mentale domene, og høyere utdanningsnivå, men ingen forskjell i yrkesaktivitet. Konklusjon: Funnene fra de fire delstudiene kompletterer hverandre. Diskrepansen mellom funnene fra intervjuene og spørreskjemaene belyser en bredde og dybde i opplevelsene avlivet med barneleddgikt som det ikke er mulig å avdekke bare gjennom bruk av standardiserte spørreskjemaer. Selv om funnene viser vedvarende positive utfall av sykdommen både fysisk og psykososialt fra første til andre oppfølging, viser unge mennesker med barneleddgikt at livet innebærer kamp og tilpasning til en usikker livssituasjon fysisk, psykisk og sosialt.

Introduction: The inflammation plays the essential role in the bone loss in juvenile idiopathic arthritis (JIA). Proinflammatory cytokines and also glucocorticoids (GCs) may activate bone resorption by osteoclasts. Simultaneously, bone formation can be attenuated, especially by inhibitors of proteins, which control the osteoblast differentiation. The aim was to verify the hypothesis that in patients with highly active JIA, reduction of bone formation via Wingless (Wnt) proteins inhibitors - Dickkopf 1 (Dkk-1) and sclerostin could be found. Except the densitometry measurements of bone and lean mass, we assessed markers of disease activity, bone metabolism and remodeling in young adult patients with JIA before and during 2 years of anti TNFα (tumour necrosis factor α) treatment, which decreases disease activity. Results: In patients with JIA before antiTNFα treatment, bone mineral density (BMD, g/cmš) was significantly reduced compared to controls. Values of BMD and body composition in JIA significantly depended on disease duration and GCs treatment. Serum concentration of sclerostin was significantly elevated in JIA compared to values in healthy controls. Values of the other monitored markers did not differ between JIA and controls. In patients with JIA, Dkk-1 correlated positively with C-reactive...

A artrite idiopática juvenil (AIJ) é uma doença crônica e sistêmica, que se inicia em crianças e adolescente menores de 16 anos de idade, sendo caracterizada por uma sinovite crônica nas articulações. Os objetivos da presente pesquisa foram avaliar a presença de DTM em pacientes com AIJ por meio da utilização dos Critérios de Diagnóstico para Pesquisa da Desordem Temporomandibular (RDC/TMD) e, posteriormente, correlacionar o diagnóstico clínico de DTM com os achados da Tomografia Computadorizada de Feixe Cônico (TCFC) e com a idade, gênero sexual, tempo do início dos sintomas, tempo de tratamento e subtipo da AIJ dos pacientes. Foram avaliados 15 pacientes (oito do gênero sexual masculino e sete do gênero feminino) com idade variando entre seis e 28 anos (média de 16,3 anos). Foram encontradas 25 (83,3%) articulações temporomandibulares (ATM) com diagnóstico clínico de DTM. Apesar das alterações articulares terem sido frequentes na avaliação por meio da TCFC (83,3%), apenas cinco (17,7%) ATM apresentaram um diagnóstico clínico de osteoartrite ou osteoartrose. Após análise estatística dos resultados, com nível de significância de 5% (p≤0,05), pôde-se sugerir que: o diagnóstico clínico de DTM e os achados da TCFC não tiveram correlação estatisticamente significante com o gênero sexual e com o subtipo da AIJ; um maior número de diagnósticos clínicos de DTM do lado direito aumentou a probabilidade de se encontrar um maior grau de DTM no lado esquerdo e quanto maior o tempo do início dos sintomas da AIJ, maior foi o grau de DTM e maior foi a probabilidade de se encontrar alterações tomográficas bilateralmente; um número maior de alterações tomográficas do lado direito aumentou a probabilidade de se encontrar um maior grau de alteração tomográfica no lado esquerdo; as ATM do lado esquerdo dos pacientes acometidos pela AIJ numa idade mais avançada, com um início dos sintomas tendo ocorrido há mais tempo e com um maior tempo de tratamento estavam relacionadas com um maior grau de alteração tomográfica; quando o início dos sintomas da AIJ ocorreu há mais de três anos, maior foi o grau de DTM (lado direito e esquerdo) e o grau de alteração tomográfica (lado esquerdo) e também foi maior a probabilidade de se encontrar diagnóstico de DTM e alterações tomográficas bilateralmente; quando a idade no 8 momento da avaliação foi superior a 16 anos, maior foi o grau de DTM e de alteração tomográfica encontrado (lado esquerdo). / Temporomandibular disorders (TMD) are alterations triggered by joint and/or muscle disorders in the orofacial region characterized by expressing pain or dysfunction. Juvenile idiopathic arthritis (JIA) is a chronic and systemic disease, which begins in children and adolescents under 16 years old and is characterized by a chronic synovitis in the joints. The objectives of this research were to evaluate the presence of TMD in patients with JIA using Research Diagnostic Criteria to Temporomandibular Disorders (RDC/TMD), and subsequently to correlate the clinical diagnosis of TMD with the findings of Cone Beam Computed Tomography (CBCT) and with the age, gender, time of symptoms onset, treatment time and subtype of JIA patients. Fifteen patients (eight male and seven females) aged between six and 28 years (mean age of 16.3 years) we evaluated. Twenty-five (83.3%) temporomandibular joints (TMJ) had clinical diagnosis of TMD. Despite joint alterations have been frequent in the evaluation by CBCT (83.3%), only five (17.7%) ATM had a clinical diagnosis of osteoarthritis or osteoarthrosis. After statistical analysis of the results, with significance level of 5% (p ≤ 0.05), it was suggested that: clinical diagnosis of TMD and the findings of TCFC had no statistically significant correlation with gender and subtype of JIA; a greater number of clinical diagnoses of TMD on the right-hand side increased the probability of finding a greater degree of TMD on the lef-hand side, and the longer the time from symptom onset JIA, the greater the degree of TMD and the probability of finding tomographic alterations on both sides; a greater number of tomographic alterations on the right-hand side increased the probability of finding a greater alteration degree on the left-hand side tomographic; the ATM on the left-hand side of patients affected by JIA at a later age, having the symptoms onset beginning longer ago and a longer duration of treatment were related to a greater degree of tomographic alterations; when the JIA symptoms onset began more than three years ago, the greater was the degree of TMD (righthand and left-hand side) and the degree of tomographic alteration (left side), also was greater the probability of finding TMD diagnosis and tomographic alterations on both sides; when the patients are older than 16 by the time of the evaluation, the greater the degree of TMD and alterations found tomographic (left-hand side).

A literatura relata uma alta prevalência de sinais e sintomas de desordens temporomandibulares (DTM) em pacientes com AIJ. Foram avaliadas as articulações temporomandibulares de 15 pacientes (30 articulações) com diagnostico de artrite idiopática juvenil por meio de tomografia computadorizada de feixe cônico com o objetivo de investigar alterações ósseas (aplainamento, erosão osteófito e esclerose). Dos pacientes avaliados, 13 possuíam pelo menos um dos tipos de alterações investigadas (87%) e apenas dois pacientes não apresentaram alterações registradas tomograficamente. Aplainamentos e osteófitos foram as alterações mais encontradas nos côndilos mandibulares (53,3%) e 43% dos complexos fossa/eminências articulares encontravam-se aplainadas. As alterações encontradas foram mais freqüentes do que a literatura relata e justifica-se pelo melhoramento da ferramenta de diagnostico – tomografia computadorizada de feixe cônico. / Juvenile Idiopathic Arthritis (JIA) is a chronic rheumatic disease of childhood, accounting for physical limitations, psychological, social and even the patients in the short and / or long term, and is characterized by inflammation of the synovium in one or more joints.

Were evaluated the temporomandibular joints of 15 patients (30 joints) with diagnosis of juvenile idiopathic arthritis using cone beam computed tomography in order to investigate bone changes (flattening, erosion, osteophytes and sclerosis). Among the patients, 13 had at least one of the types of alterations analyzed (87%) and only two patients showed no changes recorded tomographically. Flattening and osteophytes were the most found in the mandibular condyles and (53.3%) and 43.3% of the complexe fossa/articular eminences were flattened. The alterations were more frequent than the literature reports and are justified by the improvement of diagnostic tools - cone beam computed tomography.
