Night time blood pressure and cardiovascular structure in a middle-aged general population in northern Italy: the Vobarno Study. J Hum Hypertens 2001; 15:879-85. [PMID: 11773992 DOI: 10.1038/sj.jhh.1001286] [Citation(s) in RCA: 33] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2001] [Revised: 07/17/2001] [Accepted: 07/17/2001] [Indexed: 11/08/2022]
Abstract
The aim was to determine, in a cross-sectional study, the relation between structural alterations in the heart and carotid arteries, and blood pressure (BP) changes from day to night time, measured by ambulatory BP (ABP). In 225 untreated subjects (107 F, 118 M, age range 48-64 years) and 59 treated subjects (24 M, 35 F, age range 50-64), living in a small town of northern Italy (Vobarno, Brescia) carotid intima media thickness as well as the occurrence of plaque, were evaluated by ultrasound. Echocardiographic left ventricular (LV) mass was measured according to the Penn Convention. BP was determined by clinic measurement and by 24-h non-invasive ABP monitoring. Subjects were divided in two groups, according to the decrease of night time systolic BP (SBP) "dippers" (SBP decreased by at least 10% during night time) and "non-dippers" (decrease of night time SBP <10%). The intima-media thickness in the common carotid, in the carotid bifurcation, in the internal carotid artery and average intima-media thickness were significantly greater in untreated non-dippers as compared with dipper subjects (ANOVA P < 0.05). A significantly higher prevalence of plaque was observed in untreated non-dippers as compared with dippers (P = 0.002). After adjusting for age, sex, 24-h SBP, and smoking, IMT in the carotid bifurcation and average intima-media thickness remained significantly greater in non-dipper subjects (P < 0.05 for all comparisons). No significant differences in LV mass were observed between dippers and non-dipper subjects. In conclusion, in a general population of unselected middle-aged subjects, night time BP values, among other risk factors, seem to represent an important determinant of carotid wall structure.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Familial defective apolipoprotein B-100, a dominantly inherited form of hypercholesterolemia caused by a single Arg3500Gln mutation, is silent in childhood but may confer a high risk of cardiovascular disease in adulthood. The objective was to determine the prevalence of familial defective apolipoprotein B-100 in hypercholesterolemic French children and to provide a basis for targeting screening efforts in this population. METHODS One hundred ninety children attending 13 pediatric clinics distributed throughout France were included based on the presence of type IIa hypercholesterolemia with a plasma low-density lipoprotein-cholesterol level of more than 130 mg/dL. The Arg3500Gln mutation was detected in dried blood spots using a polymerase chain reaction assay combined with enzymatic restriction. RESULTS Three hyperlipidemia phenotypes were found: monogenic dominant pure hypercholesterolemia (n = 117), polygenic hypercholesterolemia (n = 43), and combined hyperlipidemia (n = 11). Three unrelated children were heterozygous for the Arg3500Gln mutation; all three had monogenic dominant pure hypercholesterolemia (3/94 families; 3.2%), yielding a prevalence of 1.83% (3/164) in hypercholesterolemic children, which is similar to prevalences reported in European adults. CONCLUSIONS The familial defective apolipoprotein B-100 mutation was common (1/31) in children with a phenotype of familial hypercholesterolemia, supporting screening in this population with the goal of preventing premature cardiovascular events.

Abstract
We report herein the results of the cross-cultural adaptation and validation into the Italian language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. The Italian CHAQ was already published in the literature and was therefore revalidated while the Italian CHQ was fully cross culturally adapted with 3 forward and 3 backward translations, and than validated. A total of 1,192 subjects were enrolled: 404 patients with JIA (16% systemic onset, 31% polyarticular onset, 21% extended oligoarticular subtype, and 32% persistent oligoarticular subtype) and 788 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being when compared to their healthy peers. In conclusion the Italian version of the CHAQ-CHQ are reliable, and valid tools for the functional, physical and psychosocial assessment of children with JIA.

Abstract
Authors made a comparison between 167 suffers from Scheuermann's disease (SD), 70 adolescence idiopathic scoliosis (AIS) and 132 age, sex, height, weight, pubertal developmental stages (Tanner stages) matched controls. The height percentile in 130 cases was also determined. The bone mineral density (BMD) was measured by pQCT on the non dominate sided radial bone. The alkaline phosphatase (AP) level increased at the beginning of puberty and in the puberty in SD. In SD the trabecular Z-score of BMD was significantly decreased in Tanner stage 1 to 4 in both boys and girls. It was not found any significance difference, however, in Tanner stage 5, while in AIS girl no significance decrease of BMD was found. In SD good correlation could be demonstrated between increase in AP and decrease in trabecular Z score r = 0.2, while did not correlate with height percentile. The AP level's increase, and radiomorphometric data of SD severity (intervertebral space narrowing and antero-posterior diameter increase of vertebral body) shows a significant correlation with decreased trabecular Z-score in the period of prepuberty.

Abstract
OBJECTIVE To determine whether demographic, clinical, and laboratory variables measurable at baseline predict the clinical efficacy or major toxic effects of methotrexate (MTX) therapy in children with chronic arthritis. STUDY DESIGN Patient eligibility criteria: (1) monitored in our unit between 1986 and 1996 with a diagnosis of chronic arthritis and (2) treatment with MTX as the sole second-line agent and for at least 6 months. Outcomes investigated: (1) short-term (6-month) clinical response, (2) complete disease control, (3) disease relapse after MTX discontinuation after complete disease control, (4) aminotransferase elevation, (5) gastrointestinal toxicity. Independent variables that showed significant results with univariate tests or were clinically relevant for each outcome underwent multiple logistic or Poisson regression analyses. RESULTS Eighty patients were available for analysis. The disease onset subtype was systemic in 37 patients, polyarticular in 20 patients, and oligoarticular in 23 patients (all with polyarticular course: extended oligoarticular subtype). The extended oligoarticular subtype was the best predictor for both the short-term clinical response (odds ratio 6.80, P =.02) and, together with a better functional ability, the complete disease control (rate ratio 3.85, P =.03 and rate ratio 3.29, P =.006, respectively). Patients with this subtype of chronic arthritis tended to have earlier, and more frequently, a disease relapse after MTX discontinuation. Thrombocytosis was the only significant risk factor for liver biochemical abnormalities (rate ratio 2.94, P =.008), whereas no variable yielded significant results for gastrointestinal toxicity. CONCLUSION Patients with extended oligoarticular chronic arthritis were more likely to benefit from MTX therapy and to have a relapse after treatment discontinuation, suggesting that MTX is distinctly more effective in this subset of chronic arthritis.

Abstract
OBJECTIVE To investigate the efficacy of folinic acid in reducing the side effects associated with methotrexate (MTX) therapy in children with juvenile idiopathic arthritis (JIA) and to determine whether folate supplementation may reduce the benefit of MTX administration. METHODS This was a retrospective, non-controlled study. Inclusion criteria were: 1) diagnosis of JIA according to the Durban 1997 criteria; 2) treatment with low to intermediate doses of MTX (10-20 mg/m2/week) as the sole second-line agent for at least 6 mos.; and 3) supplementation with folinic acid (2.5-7.5 mg) in a single weekly dose 24 hrs after MTX administration. All patients were started on folinic acid only after the development of a side effect. Exclusion criteria were: treatment with higher doses of MTX (> 20 mg/m2/week). The outcomes investigated were: hepatotoxicity (liver transaminase increase), gastrointestinal toxicity, disease flare, and clinical remission. The number of episodes per patient-year of MTX treatment of each outcome before and after folinic acid supplementation was compared by the Wilcoxon matched pairs test. RESULTS A total of 43 children with JIA were included in the study. The mean duration of treatment before and after folinic acid supplementation was 1.1 years and 1.8 years, respectively. After the start of folinic acid supplementation, the mean number of episodes per patient-year of hepatotoxicity and gastrointestinal toxicity decreased from 2.30 to 0.32 (p < 0.001) and from 1.09 to 0.29 (p = 0.002), respectively. The mean number of disease flares and clinical remissions per patient-year did not change significantly. CONCLUSION In our JIA patients, folinic acid supplementation resulted in a significant reduction in the most common side effects of MTX, without affecting the clinical efficacy of the drug.

Abstract
OBJECTIVE To compare the relative responsiveness of outcome measures in children with oligoarticular course juvenile chronic arthritis (JCA). METHODS Twenty-six consecutive children with JCA and < or =4 joints involved were assessed at admission and after 3 months of followup. Outcome measures included physician and parent global assessments, functional ability as measured by the Childhood Health Assessment Questionnaire (CHAQ), articular variables, and laboratory indicators of systemic inflammation. Responsiveness was calculated with the standardized response median, the effect size, and the Guyatt method. RESULTS The physician global assessment of disease activity, the active joint count, the global articular severity score, and the number and score of swollen joints proved consistently more responsive with either responsiveness measure used. The parent global assessment of the child's well being, the scores of joints with pain/tenderness and limited range of motion, and the number of joints with limited range of motion showed intermediate responsiveness. The CHAQ, morning stiffness, and laboratory indicators of systemic inflammation were the least responsive measures. CONCLUSION The subjective estimation of disease activity by the physician and the articular variables were the more responsive outcome measures in children with oligoarticular JCA. The assessment of functional ability as measured by the CHAQ showed a poor sensitivity to clinical change in this subset of patients with JCA.

Abstract
Gastrointestinal complications of Schönlein-Henoch purpura are frequent and sometimes severe. However, there seem to be no reports of liver involvement. A child is described in whom Schönlein-Henoch purpura was complicated by bile duct lesions, resulting in biliary cirrhosis and requiring liver transplantation. At surgical removal, the liver had lesions of bile ducts and of adjacent small blood vessels in the hilum, very similar to those complicating hepatic artery thrombosis after liver transplantation. These findings suggest that Schönlein-Henoch purpura can be complicated by vasculitis of the peribiliary vessels resulting in ischemic necrosis of the bile ducts. Schönlein-Henoch purpura can be added to the list of causes of ischemic cholangiopathies.

Abstract
Autologous transplantation of hematopoietic stem cells has recently been proposed as a possible treatment for autoimmune diseases that are associated with a very severe prognosis. A 12-year-old girl who, since 4 years of age, had systemic sclerosis with progressive pulmonary involvement underwent autologous peripheral blood-derived stem cell transplantation (aPBSCT) using CD34+ selection, cyclophosphamide, and the infusion of the monoclonal antibody CAMPATH-1G. Following transplantation, in the absence of any treatment other than symptomatic therapy, the patient's exertional dyspnea and alveolitis disappeared and she experienced a marked improvement in skin score, height velocity, and general well-being that has persisted 2 years after the transplantation procedure. Autologous PBSCT associated with the infusion of the monoclonal antibody CAMPATH-1G appears to be a useful therapy for otherwise intractable forms of progressive systemic sclerosis.

Abstract
OBJECTIVE To examine the responsiveness of the disease activity measures more commonly used in juvenile chronic arthritis (JCA) clinical trials. METHODS Data were obtained from an open-label, non-controlled, multicentre trial designed to investigate the efficacy of methotrexate (MTX) in children with JCA. Outcome measures, including physician and parent global assessments, functional ability measures, articular variables, and laboratory indicators of systemic inflammation, were assessed at baseline and after 6 months of MTX treatment in 132 patients. Responsiveness of endpoint variables was evaluated by assessing the effect size (ES) and the standardized response median (SRM). RESULTS Physician and parent global assessments were the more responsive instruments, showing ES and SRM above 1.0. Erythrocyte sedimentation rate, C-reactive protein, functional status measures and articular variables showed intermediate responsiveness. Morning stiffness, haemoglobin and platelet count were the least responsive instruments. CONCLUSION The results of our analysis indicate that subjective estimations of the disease activity, either by the physician or parents, are the most responsive instruments in the assessment of the therapeutic response in children with JCA. The responsiveness of outcome measures in JCA should be further investigated in prospective controlled studies.

Abstract
The purpose of this study was to show a gradient of possible bilateral activation for movements of the non-dominant vs. dominant hand, as well as for areas involved in complex vs. simple hand movements. A standard 1.5 T magnetic resonance imaging (MRI) system has been utilized to localize the cortical motor hand areas, using the blood oxygen level dependent contrast (BOLDc) technique and single-section fast low-angle shot (FLASH) imaging. Ten normal right-handed subjects volunteered for the study. The motor tasks consisted of simple (flexion-extension) finger movements of either hand, and complex movements (finger-to-thumb opposition in a repeating, pre-planned sequence) of the non-dominant hand. Simple movements caused contralateral activation of the primary motor area (MA); ipsilateral activation was observed for the non-dominant hand only. Supplementary motor area (SMA) was also activated, with a clear contralateral prevalence. The ratio of bilateral activation of MA did not change with complex movements of the non-dominant hand, while SMA as well as lateral premotor area were largely bilaterally activated in this task. In conclusion, the ipsilateral MA is activated for movements--even simple--performed with the non-dominant hand. There is widespread functional activity, involving both contralateral and ipsilateral SMA, for complex movements.

Abstract
We investigated the rate of radiologic progression, as measured by carpal length, in 26 children with juvenile chronic arthritis who were treated with methotrexate. After 2 years of treatment, the carpal length was significantly more deteriorated in nonresponders in both the "better" wrist (P = .001) and the "worse" wrist (P = .005). These results show that methotrexate may have a "disease modifying" potential in juvenile chronic arthritis.

Abstract
OBJECTIVE To evaluate the efficacy, safety, and corticosteroid sparing potential of methotrexate (MTX) in patients with pediatric onset systemic lupus erythematosus (SLE). METHODS The medical records of 11 patients with SLE with onset before age 16 years were reviewed. Details of clinical features, previous therapy, indications for MTX, efficacy, toxicity, and corticosteroid reduction during MTX therapy were recorded. RESULTS At the start of MTX treatment, 7 patients had nephritis, 3 malar rash, 3 arthritis, 2 skin vasculitis, and 2 thrombocytopenia. All patients were given MTX (12.5-17.0 mg/m2/week) as the sole drug therapy along with prednisone. Although many patients showed initial improvement and/or were able to reduce the prednisone dose, after 7 to 23 months 8 patients had a flare of SLE requiring increased doses of prednisone, one patient had unchanged SLE activity, and 2 patients were permanently discontinued from MTX because of toxicity. Side effects were observed in 8 (73%) patients, but only 2 (18%) discontinued MTX due to toxicity. CONCLUSION MTX given as the sole drug therapy along with prednisone did not show a major corticosteroid sparing potential in our patients with pediatric onset SLE.

Abstract
OBJECTIVE To investigate the performance of the core set of outcome measures and the preliminary definition of improvement (PDI) in the assessment of response to methotrexate (MTX) treatment in children with juvenile chronic arthritis (JCA). METHODS Data were obtained from an open label, non-controlled trial designed to investigate the efficacy of MTX in children with JCA. All patients had the core set of variables assessed at baseline and after six months of treatment. Variables in the core set are: (1) physician global assessment of disease activity; (2) parent or patient (if appropriate in age) global assessment of overall well being; (3) functional ability; (4) number of joints with active arthritis; (5) number of joints with limited range of motion; (6) erythrocyte sedimentation rate. The PDI specifies that to be classified as improved, a patient must show at least 30% improvement from baseline in three of any six variables in the core set, with no more than one of the remaining variables worsening by more than 30%. RESULTS A total of 111 JCA patients were included in the study. According to the PDI, after six months of MTX treatment 73 patients (66%) were classified as improved and 38 (34%) as not improved. Among the core set variables, parent assessment detected the highest percentage of patients improved (72%) and functional assessment the lowest (37%). CONCLUSION The PDI identifies about two thirds of patients with JCA treated with low dose MTX as improved. This proportion is similar to that expected to improve based upon a previous controlled study of low dose, oral MTX and provides preliminary evidence of the definition's validity.

Abstract
The authors review the literature during the past ten years relating to the onset of retroperitoneal hemorrhage during heparin treatment. The phenomenon may be attributed to a thrombotic genesis involving the adrenal glands and may or may not be correlated to the presence of heparin-induced immune phenomena. The severity of the phenomenon is readily understood: given that the pathology is heparin-dependent, suspension of heparin treatment is the first main step to be taken; this is evidently a cause of risk in relation to the pathology that imposes the use of heparin. The rarity of this complication means that, according to the authors, it has been undervalued. They report three cases which were brought to their attention over the past three years. On the basis of their experience, the authors underline the importance of knowing the causes that are supposed to be responsible for the complication and the study of blood coagulative status. In order not to overlook the possible adrenal genesis of the phenomenon they also recommend a careful exploration of the adrenal glands when faced with a retroperitoneal hematoma in which the source of hemorrhage cannot be identified.

Abstract
OBJECTIVE To estimate in a cross sectional analysis the degree of colinearity among the disease activity measures more commonly used in juvenile chronic arthritis (JCA). METHODS This study assessed in a single clinical evaluation three subjective variables, three measures of functional capacity, eight articular indices, and two laboratory indicators of systemic inflammation in 55 consecutive children with JCA. The relation between the clinical measures of JCA activity was determined by Pearson correlation coefficients. An r value of 0.7 or greater was considered evidence of colinearity. RESULTS Among the subjective variables, parent global assessment of overall well being and parent assessment of pain were correlated with each other; the physician assessment of disease activity did not show evidence of colinearity with any other variable. The functional status measures were correlated with each other, but not with the indices of articular inflammation. There was a high degree of colinearity among the articular variables, with the number of active joints and the overall severity score being correlated with each other as well as with all the single articular indices. The laboratory variables were correlated with each other, but not with any of the articular, functional or subjective variables. CONCLUSION Our results show a high degree of colinearity among the disease activity measures belonging to the same category, whereas this is uncommon for variables that investigate different domains of disease activity. These data underline the need to include the evaluation of each domain in the assessment of JCA activity.
