Discordance between physician's and parent's global assessments in juvenile idiopathic arthritis.

OBJECTIVE: To investigate the discrepancy between physician's and parent's global assessments of disease status and the factors explaining discordance in patients with juvenile idiopathic arthritis (JIA). METHODS: The mothers of 197 patients with JIA rated the child's overall well-being on a 10 cm visual analogue scale (VAS) and the attending physician rated the child's overall disease activity on a 10 cm VAS. A discordance score was calculated by subtracting the physician's global assessment from that of the parent's, leading to the definition of three patient groups: (1) no discordance, when physician's and parent's assessments were within 1 cm of each other; (2) negative discordance, when parent's assessment was underrated relative to the physician; and (3) positive discordance, when parent's assessment was over-rated relative to the physician. Negative and positive discordance was defined as 'marked' when the difference between the two assessments was greater than 3 cm. RESULTS: No discordance was found in 40.6% of the patients. Negative discordance was found in 51.3% of the patients, with 34% showing marked discordance. Positive discordance was found in 8.1% of the patients, with 2% showing marked discordance. Significant differences between groups included a shorter disease duration among patients with a markedly positive discordance (P = 0.02) and a greater frequency of ongoing second-line drug therapy among patients with no discordance or with positive discordance (P = 0.008). Patients with no discordance or with marked positive discordance had a significantly lower joint counts (P = 0.02-0.004). CONCLUSION: Parents and physicians often perceive the health status of children with JIA differently, with parents providing most frequently lower rating.

Relationship between damage accrual, disease flares and cumulative drug therapies in juvenile-onset systemic lupus erythematosus.

Our objective was to investigate the pattern of damage accumulation in patients with juvenile-onset systemic lupus erythematosus (JSLE) and the relationship between damage accrual, disease flares and cumulative drug therapies. All patients with SLE followed prospectively in three tertiary care centres were identified. Only patients who presented within 12 months of diagnosis and were followed for at least three years were included. Damage was measures based on chart review using the SLICC/ACR damage index (SDI), which was modified (M-SDI) by adding the item growth failure. Mild-moderate and severe disease flares were defined by the increase in SLEDAI-2K. The cumulative duration of drug therapies was calculated in each patient. Fifty-seven patients were included. The mean M-SDI score for the whole patient group increased over time, from 0.1 at one year to 0.8 at three years to 1.5 at five years. Ocular and renal damage and growth failure were observed most frequently. Compared to patients with stable damage, patients who accrued new damage had a significantly greater frequency of severe disease flare in the first three years of follow-up. No significant difference was observed in any cumulative drug therapy between patients who accrued damage and those who did not. Damage accrual was associated with severe disease flares, suggesting that judicious use of immunosuppressive agents to achieve prompt control of severe exacerbation of disease activity is important in minimizing damage in patients with JSLE.

EULAR/PReS endorsed consensus criteria for the classification of childhood vasculitides.

BACKGROUND: There has been a lack of appropriate classification criteria for vasculitis in children. OBJECTIVE: To develop a widely accepted general classification for the vasculitides observed in children and specific and realistic classification criteria for common childhood vasculitides (Henoch-Schönlein purpura (HSP), Kawasaki disease (KD), childhood polyarteritis nodosa (PAN), Wegener's granulomatosis (WG), and Takayasu arteritis (TA)). METHODS: The project was divided into two phases: (1) the Delphi technique was used to gather opinions from a wide spectrum of paediatric rheumatologists and nephrologists; (2) a consensus conference using nominal group technique was held. Ten international experts, all paediatricians, met for the consensus conference. Agreement of at least 80% of the participants was defined as consensus. RESULTS: Consensus was reached to base the general working classification for childhood vasculitides on vessel size. The small vessel disease was further subcategorised into "granulomatous" and "non-granulomatous." Final criteria were developed to classify a child as HSP, KD, childhood PAN, WG, or TA, with changes introduced based on paediatric experience. Mandatory criteria were suggested for all diseases except WG. CONCLUSIONS: It is hoped that the suggested criteria will be widely accepted around the world because of the reliable techniques used and the international and multispecialist composition of the expert group involved.

Weighting improves the information provided by joint counts on the severity of arthritis and its impact on patients' well-being in juvenile idiopathic arthritis.

OBJECTIVE: To develop a scoring system for juvenile idiopathic arthritis (JIA) in which joints are weighted to reflect their relative importance to children's function and to examine whether weighting increases the correlation of joint counts with subjective and laboratory outcome measures. METHODS: A weighted joint score was devised by a panel of experienced paediatric rheumatologists, who assigned a weight from 1 (not very important) to 10 (essential for key functional activities) to each joint based on its functional importance to children's physical and daily activities. The associations of simple and weighted counts of swollen, tender, limited and active joints with the physician's global assessment of overall disease activity, the parent's global assessment of the child's overall well-being and intensity of pain, the Childhood Health Assessment Questionnaire (C-HAQ), the Child Health Questionnaire (CHQ) and the erythrocyte sedimentation rate were compared using Spearman's correlation analysis in 60 unselected patients seen in the clinic and in 61 consecutive patients with disease duration > or = 5 yr. RESULTS: Weighted counts of swollen and active joints yielded greater correlation with the physician's global assessment than did simple counts. The correlation of weighted counts of swollen, painful and active joints with the parent's assessment of overall well-being and intensity of pain was superior to that provided by simple counts. Weighting increased most of the correlations between joint counts and the C-HAQ score and the physical component of the CHQ. CONCLUSION: Weighting improves the information provided by joint counts on the severity of arthritis and its impact on patients' well-being.

Relative responsiveness of condition specific and generic health status measures in juvenile idiopathic arthritis.

OBJECTIVES: To compare the relative responsiveness of condition specific measures with that of a generic health status instrument for outcome assessment of intra-articular corticosteroid (IAC) injection in patients with juvenile idiopathic arthritis (JIA). METHODS: We examined 44 consecutive patients with oligoarticular JIA before an IAC injection and after 6 months. Condition specific measures included physician's and parent's global assessments, the Childhood Health Assessment Questionnaire (CHAQ), the articular indices, and laboratory indicators of systemic inflammation. The generic health status instrument was the Child Health Questionnaire (CHQ), which was divided into two parts: the physical score (PhS) and the psychosocial score (PsS). Responsiveness statistics were the standardised response mean, the effect size, and Guyatt's method. The discriminative ability of the clinical measures in distinguishing improved from non-improved patients was evaluated with the correlation and the receiver operating characteristic methods, using the physician's and the parent's judgements of the treatment outcome as external criteria. RESULTS: All responsiveness statistics and discriminative ability assessments consistently ranked the physician's global assessment of the disease activity as the most responsive measure. The CHQ-PhS revealed superior ability in detecting baseline versus 6 month change compared with the CHAQ and the CHQ-PsS; both summary scales of the CHQ revealed better discriminative ability than the CHAQ. CONCLUSIONS: The physician's global assessment of the disease activity proved the most responsive outcome measure in our patients with JIA. The relative evaluative properties of the generic health status instrument and the CHAQ should be further investigated.

Outcome of primary antiphospholipid syndrome in childhood.

The objective of this paper is to investigate the long-term outcome of primary antiphospholipid syndrome (APS) in the paediatric age. The features of unselected patients with primary APS who had disease onset before the age of 16 years were retrospectively analysed in three Italian referralcentres. Clinical and laboratory manifestations were assessed to establish whether, at the end of follow-up, the final diagnosis was still primary APS or whether they had developed definite SLE or lupus-like syndrome. Fourteen patients, nine boys and five girls, who had the presenting clinical manifestation of APS between three and 13 years of age (median nine years) and were followed for two to 16 years (median six years). Six patients presented with deep vein thrombosis, five with cerebral stroke, two with peripheral artery occlusion and onewith myocardial infarction. During follow-up, four patients had one or more recurrences of vascular thrombosis. At last observation, 10 patients could still be classified as having primary APS, two had developed SLE, one lupus-like syndrome and one Hodgkin's lymphoma. In conclusion; our analysis suggests that some children who present with the features of primary APS may progress to develop SLE or lupus-like syndrome.

Predictors of first incidence of DSM-III-R psychiatric disorders in the general population: findings from the Netherlands Mental Health Survey and Incidence Study.

OBJECTIVE: To investigate determinants of 12-month first incidence of DSM-III-R mood disorder (MD), anxiety disorder (AD) and substance use disorder (SUD) in the general population. METHOD: Data are from the Netherlands Mental Health Survey and Incidence Study (NEMESIS), a prospective epidemiologic study in which a representative sample of 7076 adults aged 18-64 years were interviewed with the Composite International Diagnostic Interview. New cases diagnosed 12 months after baseline were compared with never diagnosed controls on sociodemographic and psychosocial variables. RESULTS: Multivariate, the only demographic variable associated with incidence of MD was female gender. The strongest predictors were negative life events and ongoing difficulties. High level of neuroticism was also associated. Incidence of AD was likewise predicted by female gender. Negative life events and ongoing difficulties were also significant predictors, though weaker than for MD. Incidence of SUD was more common among males, young adults, people not living with a partner and those experiencing positive life events. CONCLUSION: Incident MD and AD were predicted more strongly by life events, and SUD more strongly by demographic factors.

[Histopathological diagnosis of celiac disease in children and adults: 3 years' experience].

We describe our personal experience with the routine histopathologic diagnosis of coeliac disease in pediatric and adult ages, over a period of 3 years. The most important indications based on the examination of over 300 cases include: (a) the importance of a correct orientation of biopsies on Millipore filters; (b) the not regular sending of clinical and laboratory results; (c) the better correspondence of modified Marsh classification by Oberhuber to the histologic characteristics of the disease before and after dieting; and (d) the increasing incidence of coeliac disease in adult age, even though in this case series the age-class most affected was that under 11 years (75 cases, 25%).

Discordance between proxy-reported and observed assessment of functional ability of children with juvenile idiopathic arthritis.

OBJECTIVE: To determine the level of agreement between parents and clinicians in rating dysfunction in children with juvenile idiopathic arthritis (JIA). METHODS: A parent of each patient completed the Italian version of the Childhood Health Assessment Questionnaire (CHAQ). Subsequently, an examiner assessed, in a specially equipped room, the child's performance of tasks as described by the CHAQ. Demographic and clinical variables were recorded for all patients. RESULTS: Seventy consecutive JIA patients and their parents were included. The mean proxy-reported and observed CHAQ score was 0.64+/-0.53 and 0.47+/-0.62 respectively, the difference ranging from -1.75 to 1.5. There were 30 cases (43%) of agreement (difference < or =0.25 CHAQ units) between the parent's and clinician's ratings, whereas in 40 cases (57%) there was discordance (difference >0.25 CHAQ units). In 30 cases the parent rated the child's functional ability as worse than that observed by the clinician (i.e. the parent underestimated the child's function), whereas in 10 cases the parent rated the child's functional ability as better than that observed by the clinician (i.e. overestimated the child's function). Multivariate regression analysis showed that children's functional ability was overestimated by parents with increasing erythrocyte sedimentation rate and global articular severity score and underestimated with increasing level of pain. Among the functional areas of the CHAQ, the level of agreement was poorest in the areas of eating and hygiene and was best for activities. CONCLUSIONS: Discordance between proxy-reported and observed functional ability was frequent in our patients with JIA. The children's functional ability was overestimated by parents as the severity of arthritis increased and underestimated as the level of pain increased.

Methotrexate as a possible trigger of macrophage activation syndrome in systemic juvenile idiopathic arthritis.

Macrophage activation syndrome (MAS) is a potentially life threatening complication of chronic rheumatic diseases, particularly systemic juvenile idiopathic arthritis (JIA). A number of triggers have been related to the development of MAS, including viral infections, nonsteroidal antiinflammatory drug therapy, and gold salt injections. We describe a patient with systemic JIA who developed MAS shortly after receiving methotrexate, suggesting that this drug can be regarded as a potential trigger of MAS in children with JIA.

Factors affecting the efficacy of intraarticular corticosteroid injection of knees in juvenile idiopathic arthritis.

OBJECTIVE: To determine in a prospective analysis whether baseline demographic, clinical, and laboratory variables predict the outcome of intraarticular corticosteroid (IAC) injection of the knees in children with juvenile idiopathic arthritis (JIA). METHODS: We studied consecutive patients who met the criteria for the diagnosis of JIA and received their initial injection of triamcinolone hexacetonide in one or both knees. Predictor variables included sex, age, age at onset of JIA, onset subtype, disease duration, drug therapy at the time of IAC injection, physician and parent global assessment of disease status, Childhood Health Assessment Questionnaire disability index, erythrocyte sedimentation rate (ESR), C-reactive protein, involvement of other joints besides knees, amount of fluid aspirated, and dose of IAC injected. The primary outcome measure was persistence of complete clinical response at 6 months, i.e., no evidence of synovitis clinically. RESULTS: Ninety-four patients were available for analysis. At 6 months after the IAC injection, 65 (69%) patients showed a sustained complete clinical response, whereas 29 (31%) had had a recurrence of joint inflammation. Univariate statistical analyses showed that patients who had a sustained clinical response had a significantly higher ESR than those who did not (p = 0.023). The ESR was the only variable that remained in the best-fit model from multivariate logistic regression analysis (OR 2.61, p = 0.049). CONCLUSION: Our findings indicate that patients with JIA who have a higher ESR are more likely to benefit from IAC injection of the knees.

Psychiatric and sociodemographic predictors of attrition in a longitudinal study: The Netherlands Mental Health Survey and Incidence Study (NEMESIS).

This article discusses the effects of sociodemographics and the presence of psychiatric disorders diagnosed in the 12 months before the first interview by using the Diagnostic and Statistical Manual of Mental Disorders: DSM-III-R, third edition, revised, on three types of attrition (failure to locate, refusal to participate, morbidity/mortality) in the second wave (1997-1998) of the Netherlands Mental Health Survey and Incidence Study, a longitudinal, general population survey of psychopathology among 7,076 subjects aged 18-64 years. Compared with those reinterviewed successfully, persons not located at the 1-year follow-up (n = 219) were more often younger, poorly educated, urban, not cohabiting with a steady partner, and born outside the Netherlands. Refusers (n = 923) had a lower educational level. Morbidity/mortality (n = 72) was associated with higher age, lower educational level, not being employed, and somatic disorders. After adjustment for sociodemographics, none of the disorders was positively associated with refusal. Failure to locate was linked to agoraphobia, alcohol abuse, and the categories of mood, substance use, and eating disorders. Morbidity/mortality was linked to dysthymia, agoraphobia, simple phobia, obsessive-compulsive disorder, and the category of anxiety disorders. Overall attrition was only slightly higher among respondents with one or more disorders (odds ratio = 1.20, 95% confidence interval: 1.04, 1.38). Thus, psychopathology has only weak-to-moderate effects on attrition and is mainly related to failure to locate and morbidity/mortality but not to refusal.

Strauss (1969) revisited: a psychosis continuum in the general population?

Although dichotomously defined for clinical purposes, psychosis may exist as a continuous phenotype in nature. A random sample of 7076 men and women aged 18-64years were interviewed by trained lay interviewers with the Composite International Diagnostic Interview (CIDI). Those with evidence of psychosis according to the CIDI were additionally interviewed by psychiatrists. For the 17 CIDI core psychosis items, we compared a psychiatrist's rating of hallucinations and/or delusions (Clinical Psychosis; sample prevalence 4.2%) with three other possible positive CIDI ratings of the same items: (i) symptom present, but not clinically relevant (NCR Symptom; sample prevalence 12.9%); (ii) symptom present, but the result of drugs or somatic disorder (Secondary Symptom; sample prevalence 0.6%); (iii) symptom appears present, but there is a plausible explanation (Plausible Symptom; sample prevalence 4.0%). Of the 1237 individuals with any type of positive psychosis rating (sample prevalence 17.5%), only 26 (2.1%) had a DSM-III-R diagnosis of non-affective psychosis. All the different types of psychosis ratings were strongly associated with the presence of psychiatrist-rated Clinical Psychosis (NCR Symptom: OR=3.4; 95% CI: 2.9-3.9; Secondary Symptom: OR=4.5; 95% CI: 2.7-7.7; Plausible Symptom: OR=5.8; 95% CI: 4.7-7.1). Associations with lower age, single marital status, urban dwelling, lower level of education, lower quality of life, depressive symptoms and blunting of affect did not differ qualitatively as a function of type of rating of the psychotic symptom, were similar in individuals with and without any CIDI lifetime diagnosis, and closely resembled those previously reported for schizophrenia. Presence of any rating of hallucinations was strongly associated with any rating of delusions (OR=6.7; 95% CI: 5.6-8.1), regardless of presence of any CIDI lifetime diagnosis. The observation by Strauss (1969. Hallucinations and delusions as points on continua function. Arch. Gen. Psychiatry 21, 581-586) that dichotomously diagnosed psychotic symptoms in clinical samples are, in fact, part of a continuum of experiences, may also apply to the general population. The boundaries of the psychosis phenotype may extend beyond the clinical concept of schizophrenia.

Nephrotic-range proteinuria, the major risk factor for early atherosclerosis in juvenile-onset systemic lupus erythematosus.

OBJECTIVE: To determine the presence of early carotid atherosclerosis and associated risk factors in patients with juvenile-onset systemic lupus erythematosus (SLE). METHODS: The carotid intima-media wall thickness (IMT) was measured by B-mode ultrasound in patients with SLE onset before the age of 16 years and in sex- and age-matched healthy control subjects. Risk factors for atherosclerosis were determined at the time of the ultrasound scan and included traditional cardiovascular and SLE-related risk factors. RESULTS: Twenty-six patients with juvenile-onset SLE and 26 healthy controls were studied. The mean (+/- SD) IMT of the SLE patients was significantly higher than that of the control group (0.57+/-0.05 mm and 0.54+/-0.03 mm, respectively; P = 0.006). The results of IMT measurement were not correlated with the patients' age, disease duration, SLE Disease Activity Index (SLEDAI) score, Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index (DI) score, laboratory indicators of lupus activity, or cumulative prednisone dose. Patients with nephrotic-range (NR) proteinuria (> or = 3.5 gm/24 hours; n = 6) had a significantly higher IMT than did those without (n = 20) (P = 0.02). Patients with NR proteinuria also had significantly higher SLEDAI scores, SLICC/ACR DI scores, and systolic and diastolic blood pressures, and significantly higher levels of total cholesterol, low-density lipoprotein cholesterol, apolipoprotein B, and fibrinogen. No difference in any of the above variables, including the IMT, was observed when SLE patients without NR proteinuria were compared with healthy controls. CONCLUSION: These patients with juvenile-onset SLE had ultrasonographic evidence of premature atherosclerosis. The risk of early atherosclerosis may be higher in patients with NR proteinuria.

Current and residual functional disability associated with psychopathology: findings from the Netherlands Mental Health Survey and Incidence Study (NEMESIS).

BACKGROUND: Few population studies have investigated the functional disabilities that accompany specific psychiatric diagnoses. This study assesses the nature and strength of current and residual impairments in various functional domains of life. METHODS: Data were derived from the Netherlands Mental Health Survey and Incidence Study (NEMESIS), a prospective study in the Dutch general population aged 18 to 64 (N = 7147). Psychiatric diagnoses were based on the Composite International Diagnostic Interview; functional disability was assessed on the basis of the Short-Form-36 and the number of disability days. RESULTS: Psychopathology was associated with increased disability in social, emotional and physical domains of life. Disability levels varied by psychiatric diagnosis, with mood disorders showing the poorest levels of functioning, especially for vitality and social functioning; alcohol-related disorders were associated with few disabilities. Co-morbidity strongly aggravated the disability. The effect of contextual factors on disability was limited, although somatic ill health, unemployment and adverse youth history increased the likelihood of functional disability. The findings indicate that psychopathology can also have residual debilitating effects. CONCLUSIONS: Mental health care providers should be aware that the extent and the type of disability may vary with the different types of disorders and among different groups within the population. Since recovery from functional limitations may not be complete or may take more time than the remission of the psychiatric symptomatology, non-psychiatric follow-up care is needed. The high number of lost work days is relevant from an economic perspective. There is a need for illness-specific disability assessment instruments.

Psychiatric morbidity, service use, and need for care in the general population: results of The Netherlands Mental Health Survey and Incidence Study.

OBJECTIVES: This study examined the use of primary health care, mental health care, and informal care services, as well as unmet care needs, by individuals with different psychiatric diagnoses. METHODS: Data were derived from the Netherlands Mental Health Survey and Incidence Study and were based on a representative sample (n = 7147) of the general population (aged 18-64 years). RESULTS: In a 12-month period, 33.9% of those with a psychiatric disorder used some form of care; 27.2% used primary care, and 15.3% used mental health care. Patients with mood disorders were the most likely to enlist professional care; those with alcohol- and drug-related disorders were the least likely to do so. Higher educated persons who live alone, single parents, unemployed persons, and disabled persons were more likely to use mental health care. Unmet need for professional help was reported by 16.8% (men 9.9%, women 23.9%) of those with a disorder. CONCLUSIONS: Care use varies widely by diagnostic category. The role of general medical practitioners in treating persons with psychiatric disorders is more limited than was anticipated. Patients in categories associated with extensive use of professional care are more likely to have unmet care needs.
