Serum CC chemokine ligand-18 predicts lung disease worsening in systemic sclerosis.

Elevated serum CC chemokine ligand (CCL)18 reflects lung fibrosis activity in systemic sclerosis (SSc) and could be an early marker of lung function worsening. Therefore, we sought to evaluate whether serum CCL18 levels at baseline could predict worsening of lung disease in SSc. In this prospective study, 83 SSc patients were analysed longitudinally over a 4-yr observation period for the risk of occurrence of combined deleterious events, defined as a 10% decrease from baseline of total lung capacity or forced vital capacity % predicted, or death, according to serum CCL18 at inclusion. Receiver operating characteristic (ROC) curve analysis was performed for prediction of events during the first year after inclusion. The best cut-off level of serum CCL18 for prediction of a combined event within the follow-up period was 187 ng · mL(-1), with 53% sensitivity and 96% specificity (area under the ROC curve 0.86; p < 0.001). After a mean ± SD follow-up of 33.7 ± 10.8 months, a higher rate of disease progression occurred in the group with serum CCL18 levels >187 ng · mL(-1). The adjusted hazard ratio was 5.36 (95% CI 2.44-11.75; p < 0.001). In summary, serum CCL18 is an accurate predictive biomarker for the identification of patients with a higher risk of subsequent scleroderma lung disease worsening.

[DRESS syndrome caused by phenylbutazone]. / DRESS syndrome à la phénylbutazone.

The drug rash with hypereosinophilia and systemic symptoms (DRESS) syndrome is a severe drug-induced hypersensitivity syndrome. We report a 57-year-old woman suffering from a DRESS syndrome 15 days after phenylbutazone exposure. She had a skin eruption, liver involvement and hypereosinophilia. She fully recovered after drug withdrawal.

[Short-term effect of dietary-sodium intake on arterial blood pressure of patients treated with systemic corticosteroids: a prospective, randomised, crossover study]. / Effet à court terme des apports sodés sur la pression artérielle des patients recevant une corticothérapie systémique: étude prospective, randomisée, croisée.

INTRODUCTION: It is unknown if the level of dietary-sodium intake influences blood pressure in patients receiving systemic corticosteroids. METHODS: Randomized, single centre, crossover trial involving patients starting systemic corticosteroid therapy and having initial blood pressure less or equals to 159/99 mm Hg. The first period of sodium regimen was randomized (<3 g/j versus >6 g/j) and each period of sodium regimen lasted 3 weeks. No washout period was performed. Blood pressure was recorded for each patient at inclusion and after 3 weeks and 6 weeks. Moreover, all patients were asked to record on a standardized questionnaire everything they ate during 1 week of each period regimen. Questionnaires were analysed by a dietician for mean daily energy and sodium intakes during each period. Mixed models were used to estimate the relationship between sodium intake and blood pressure variations. RESULTS: Between June 2006 and June 2008, 49 patients were randomized, 24 in group 1 (first period regimen=salt<3g/day; women: 63%; mean age: 56+/-21 years; baseline prednisone dosage: 54+/-19 mg/day) and 25 in group 2 (first period regimen=salt>6g/day; women: 56%; mean age: 60+/-19 years; baseline prednisone dosage: 56+/-16 mg/day). Mean daily salt intakes were 2.5+/-1.8 and 9.3+/-1.9 g/day during the first period and 7.8+/-3.2 and 3.8+/-2.9 g/day during the second period, respectively for group 1 and group 2. Blood pressure variations were not significantly associated with daily salt intakes or with randomisation group. No order effect was evidenced. By comparison with baseline, systolic blood pressure increased by greater than 20 mm Hg at week 6 in five patients (2 in group 1 and 3 in group 2). CONCLUSION: At short-term, sodium intake does not seem to influence blood pressure variations in patients starting systemic corticosteroids therapy.

[Dyspnea secondary to pulmonary hypertension in a patient with splenic myeloid metaplasia]. / Dyspnée révélant une hypertension artérielle pulmonaire chez une malade ayant une métaplasie myéloïde de la rate.

There are several possible pathophysiological links between the development of pulmonary hypertension and myelofibrosis with myeloid metaplasia. We report a woman with myelofibrosis and myeloid metaplasia who presented with dyspnea and massive, painful splenomegaly. Right heart catheterization evidenced pulmonary hypertension. Her management consisted of splenic irradiation associated to sildenafil. Dyspnea in patients with myelofibrosis and myeloid metaplasia can be secondary to pulmonary hypertension and conversely the differential diagnosis of pulmonary hypertension should include a myeloproliferative syndrome.

[Internal medicine physicians' perception of frequency and impact of corticosteroid-induced adverse events]. / Perception par les médecins internistes de la fréquence et de la gêne induite par les effets indésirables d'une corticothérapie systémique prolongée.

INTRODUCTION: Whereas internal medicine physicians frequently prescribe systemic corticosteroids, it is unknown if they assess adequately the frequency and the discomfort caused by corticosteroid-induced adverse events. METHODS: Using an e-mail questionnaire sent to the 813 internal medicine physicians, members of the French National Society of Internal Medicine, we assessed their perception of the frequency and the discomfort induced by the adverse events of long-term (that is, over or at three months) corticosteroid therapy. At the same time, 121 corticosteroid-treated patients, consulting in a department of internal medicine completed an anonymous questionnaire about the frequency and the discomfort caused by the adverse events of their therapy. RESULTS: Three hundred and thirty-six out of 813 internal medicine physicians answered to the questionnaire (response rate: 41%) and 115 of the 121 questionnaires distributed to patients were exploitable. The physicians were predominantly male (71%) working mainly in tertiary centers (53%). The mean length of corticosteroids therapy for patients was 44+/-38 months and the mean daily dosage was 15+/-14mg. Lipodystrophy, trophic skin disorders, neuropsychiatric disorders and insomnia were frequent and reported by more than half of patients. The frequency of neuropsychiatric and skin disorders and of lipodystrophy estimated by practitioners was markedly lower than the frequency reported by patients. If morphological changes (weight-gain and lipodystrophy) were cited by practitioners as the most discomforting adverse event, in agreement with patients' opinion, physicians underestimated the discomfort caused by neuropsychiatric disorders and insomnia. CONCLUSION: Frequency and discomfort caused by corticosteroid-induced neuropsychiatric disorders are underestimated by internal medicine physicians.

[Liver infarcts with early HELLP syndrome and probable catastrophic antiphospholipid syndrome]. / Infarctus hépatiques associés à un syndrome HELLP précoce et un probable syndrome catastrophique des antiphospholipides.

INTRODUCTION: Among microangiopathic disorders of pregnancy, catastrophic antiphospholipid syndrome (CAPS) is a maternal and fetal life-threatening disorder. Hepatic involvement of this multi-systemic disorder can be confused with HELLP syndrome, occurring usually later in the course of pregnancy. CASE REPORT: We report a case of probable CAPS with hepatic disease in a pregnant woman at 13 week's gestation, with antiphospholipid syndrome and biological features of HELLP syndrome. Unspecific hepatic imaging, well-described in our case allowed undelayed therapy. CONCLUSION: CAPS and HELLP syndrome, both severe microangiopathic disorders, may be associated. Nosological distinction does not modify treatment strategy, which is a maternal and foetal emergency, but their overlapping requires aggressive and early management.

[Frequency of self-reported penicillin allergy in the area of Seine-Saint-Denis (France)]. / Fréquence de l'allergie à la pénicilline autodéclarée dans le département de Seine-Saint-Denis.

PURPOSE: Penicillin allergy is a well-known notion among the general population. Because it is rarely questioned, many patients carry this label unnecessarily and cannot use this efficient and cheap antibiotic family. In previous studies, 8-10% subjects declare a penicillin allergy. But these data came mainly from studies done in hospitals and we found interesting to evaluate a general non-hospitalised population. METHODS: We set up a study in ambulatory patients of Seine-Saint-Denis (French geographic area in the north east of Paris). It was a transversal study, on a single day, in March 2005. Hundred general practitioners were randomised in this geographic area. All their patients from that day were included and were asked to complete a simple questionnaire. RESULTS: Among 1057 patients who participated, 99 (9.4%) declared to be allergic to penicillin. Penicillin A was the most cited antibiotic. The most frequently reported clinical manifestations were skin rash (58.6%) and 13 patients (13.1%) reported some severe signs (coma or emergency hospitalisation) of which 11 were anaphylactic shock; eight patients (8.8%) reported digestive signs less compatible with an allergic mechanism. Asthma and eczema appeared to be significantly reported to penicillin allergy in our population sample. CONCLUSION: The percentage of self-declared allergy found in this study is similar to previous publications. Among penicillins, Penicillin A is the most frequently involved. This study also shows the importance of meticulously questioning patients as it can correct a false diagnosis of penicillin allergy.

[Primary chronic autoimmune neutropenia successfully treated with sirolimus]. / Neutropénie auto-immune primaire avec autoanticorps antineutrophiles traitée avec succès par sirolimus.

We report a 74-year-old man with severe chronic primary neutropenia (neutrophil count: 390 per millimeter cube) uncovered following surgery for perianal abscess collection. Clinical, laboratory and roentgenographic findings revealed no abnormality. Antineutrophil antibodies were positive in two consecutive serum samples. Under cyclosporine, neutrophil count reached 1970 per millimeter cube. However, this therapy was discontinued due to new onset of severe renal failure. After six weeks, neutrophil count was 950 per millimeter cube and sirolimus was started, resulting in renal function improvement and resolution of neutropenia.

[Schwannoma of the duodenojejunal angle]. / Schwannome kystique de l'angle duodénojéjunal.

Neurogenic tumors of the small intestine are extremely rare. Although schwannoma is often clinically indolent for many years, complications such as gut compression or bleeding might occur. In these cases, surgical management is required. We reported a case of asymptomatic schwannoma of the duodenojejunal angle. Surgical treatment was performed to provide definitive immunohistochemistry diagnosis and to prevent complications.

[Münchausen syndrome with forgery on biologic results. A case report]. / Pseudoleucémie par falsification d'examens biologiques: genèse d'un syndrome de Münchausen.

Münchausen syndrome is a disorder defined by the following: acute factitious symptoms leading to inappropriate investigation and therapy, a restless journey from hospital to hospital and autobiographical falsification. We report here a 20-year-old woman who presented at our hospital consultation of internal medicine with laboratory-test results suggesting the diagnosis of leukemia. A new complete blood cells count and a medullogram by sternal puncture did not show any abnormality. Comparative examination of laboratory-test sheets lead to the diagnosis of Münchausen syndrome as some results had been falsified. With unlimited access to information through internet and word or image processing softwares, laboratory results have become easy to falsify nowadays, particularly for patients with Münchausen syndrome, who may then be quite difficult to diagnose accurately in the context of medical consultation.

[Long-term systemic corticosteroid-therapy associated measures: description of the French internal medicine physicians' practices]. / Mesures adjuvantes à une corticothérapie systémique prolongée : description des pratiques des médecins internistes français.

INTRODUCTION: Except for the prevention of osteoporosis, no consensual recommendations are available regarding the therapeutic measures associated with the prescription of long-term corticosteroid therapy. The aim of this study was to assess the internal medicine physicians' practices regarding the prescription of long-term corticosteroid therapy. METHODS: In September 2007, we sent, by e-mail, a questionnaire to 813 internal medicine physicians, members of the French National Society of Internal Medicine. With this questionnaire, we assessed the frequency of prescription of measures sometimes associated with systemic corticosteroids and for whom no consensual recommendations were available (dietary advices, physical training, potassium supplementation, gastric protection, influenza vaccination and prescription of hydrocortisone). RESULTS: Three hundred and thirty-six out of 813 internal medicine physicians completed the questionnaire (response rate: 41%). The practitioners were predominantly male (71%) and mainly engaged in tertiary centres (53%). Regarding the dietary measures associated with the prescription of corticosteroids, low-sodium diet was recommended by most of the physicians, 69% of them prescribing such dietary regimen in more than 80% of their corticosteroid-treated patients. The concomitant prescription of caloric restriction, low-carbohydrate diet and/or high-protein diet was not consensual. The prescription of muscular physiotherapy was unusual, 74% of physicians prescribing such reeducation in less than 20% of their patients. The frequency of recommendation for daily physical training varied between physicians as well as for potassium supplementation, gastric protection, influenza vaccination or hydrocortisone prescription. CONCLUSION: There is no consensus between French internal medicine physicians regarding most of the measures, which must be prescribed in association with a long-term corticosteroid therapy.

High plasma leptin predicts an increase in subcutaneous adiposity in children and adults.

OBJECTIVE: To investigate the hypothesis that plasma leptin may predict adiposity changes. DESIGN: A population-based cohort study. SETTING: Fleurbaix and Laventie, in the north of France. SUBJECTS: In all, 1175 subjects participated, of whom 946 completed measurements at baseline (1999) and follow-up (2001). After excluding 64 subjects obese at baseline, 882 subjects (478 adults, 404 children 8 years and over) were included in the analysis. INTERVENTIONS: We measured plasma leptin concentrations at baseline and various adiposity parameters at baseline and follow-up. Partial correlation coefficients (r(p)) between baseline plasma leptin and each adiposity indicator at follow-up were calculated with adjustment for baseline age, pubertal stage, adiposity and familial correlations between siblings. RESULTS: Changes in body mass index and percentage body fat were not related to baseline plasma leptin. High baseline plasma leptin predicted an increase (r(p) (P-value)) in the sum of the four skinfolds (0.18 (<0.0001)), the waist circumference (0.16 (0.0003)) and the waist-to-hip ratio (0.29 (<0.0001)) in adults only, and in the hip circumference in adults (0.20 (<0.0001)) and children (0.22 (<0.0001)). After adjustment for a set of four adiposity variables at baseline (percentage body fat, skinfolds, waist and hip circumferences), baseline plasma leptin predicted only changes in the sum of the four skinfolds in adults (0.15 (0.001)), with similar tendency although not significant in children (0.08 (0.13)). CONCLUSIONS: A high leptin relative to baseline fat mass predicts fat mass gain over time, mainly in the subcutaneous location.

ANCA-related crescentic glomerulonephritis in systemic sclerosis: revisiting the "normotensive scleroderma renal crisis".

The scleroderma renal crisis is characterized by acute onset of severe hypertension and by rapidly progressive hyperreninemic renal failure. There is, however, a very limited subset of patients with rapidly progressive renal failure who remain normotensive and develop ANCA-positive crescentic glomerulonephritis. We report a case of normotensive acute renal failure secondary to anti-MPO antibody-associated crescentic glomerulonephritis in a patient with diffuse systemic sclerosis. She was referred to our department with normal blood pressure and no extrarenal clinical manifestation ofvasculitis. She presented with rapidly progressive renal failure, microscopic hematuria and minimal proteinuria. P-ANCA were positive by immunofluorescence, with ELISA-confirmed specificity for myeloperoxidase. Renal biopsy revealed typical features of pauciimmune glomerulonephritis with crescent formation and fibrinoid necrosis. The patient was initially treated with i.v. cyclophosphamide only. Because of ongoing deteriorating renal function, additional treatment with intravenous pulses of methylprednisolone followed by oral prednisone was started and allowed renal function improvement. After 9 months, serum creatinine had almost returned to normal level with minimal proteinuria, no hematuria and negative ANCA testing. Control kidney biopsy only revealed scar lesions. The association of ANCA-positive crescentic glomerulonephritis and systemic sclerosis is a very rare event. Treatment with intravenous cyclophosphamide and corticosteroids allows rapid and long-term improvement of renal function. The onset of typical scleroderma renal crisis triggered by high-dose corticosteroids is unlikely but requires a close follow-up of patients with overlapping systemic sclerosis. Diagnosis and treatment are discussed and previously published cases are reviewed.

[The contribution of computed tomography coronary angiography in Kawasaki disease in adult patients. Report of two cases]. / Apport du scanner coronaire dans la prise en charge de la maladie de Kawasaki chez l'adulte. A propos de deux cas.

OBJECTIVES: During the past few years, multislice computed tomography coronary angiography has made great progress in terms of spatial and temporal resolution. Results on detection and quantification of stenoses are excellent. We found interesting reporting its achievements in aneurismal coronaropathies such as the Kawasaki disease. METHODS: We searched for young adults with Kawasaki disease who had a multislice computed tomography coronary angiography available. Several hospitals in the Paris area have been contacted and only two observations have been kept. RESULTS: Computed tomography provided higher performance than coronarography for the measurement of the real diameter of an aneurism taking into account the mural thrombus, evaluation of its links with the collateral branches and the other aneurisms, assessment of the development of recanalized vessels and the degree of development of collateral vessels, and visualization of non-circulating aneurisms which were not detected with coronary angiography. In addition, the evaluation of the location and the degree of the stenoses by the computed tomography matched the coronary angiography data. It was not possible to conclude with this observations that the computed tomography is better for the diagnostic of Kawasaki disease. CONCLUSION: Multislice computed tomography coronary angiography will be likely more and more used to detect and follow coronary anomalies in case of Kawasaki disease among teenagers and young adults. It is recommended for monitoring medium or large aneurisms in order to evaluate their progression to stenosis.

[Systemic corticosteroid therapy: patients' adherence to dietary advice and relationship between food intake and corticosteroid-induced lipodystrophy]. / Corticothérapie systémique et alimentation: suivi des recommandations diététiques et relation entre apports alimentaires et apparition d'une lipodystrophie.

PURPOSE: No data is available about: 1) the adherence of corticosteroid-treated patients to dietary advice provided by physicians; 2) the relationship between food intake and the corticosteroid-induced lipodystrophy (CIL). METHODS: We conducted a cohort study in 2 French tertiary centers between June 2003 and May 2005 and enrolled all consecutive patients starting long-term systemic corticosteroid therapy. They received individual dietary advice from a qualified dietetician and were asked to record on a standardized questionnaire everything they ate during one week of the first and third months of treatment, including details of each meal. Each questionnaire was analysed by two qualified dieteticians for daily calorie, carbohydrate, fat, protein and sodium intake. Moreover, 3 investigators assessed the development of CIL from standardized patients' photographs. The relationship between food intake and CIL was investigated by a multiple logistic regression model. RESULTS: Eighty-eight patients were included and 80 were monitored until at least month 3 (women: 76%, mean age: 59.1+/-18.7 years). Most patients (65%) had giant-cell arteritis or connective tissue disease. The mean initial dosage of prednisone was 54+/-17 mg/day and the mean M3 dosage was 31+/-15 mg/day. Most patients were adherent to dietary advice during the first 3 months of therapy except for protidic ration which was below expected value. Sodium restriction was more strictly followed by women than by men. Multivariate analysis showed independent relationship between CIL and higher calorie intake (>30 kcal/kg/day). No relationship was evidenced between carbohydrate, protein, fat or sodium intake and the risk of CIL. CONCLUSION: During the first 3 months of therapy, corticosteroid-treated patients are adherent to dietary advice. A calorie-controlled alimentation could be beneficial to limit the risk of CIL.

[In-hospital mortality and stay duration of internal medicine patients: prognosis value of biochemical markers commonly performed on admission]. / Mortalité hospitalière et durée de séjour des patients non programmés en médecine interne: valeur pronostique de paramètres biochimiques usuels à l'admission.

PURPOSE: Little is known about prognosis values of biochemical markers in internal medicine patients. We have examined retrospectively the relationship between inhospital mortality or stay duration and several biochemical markers commonly performed on admission in internal medicine patients. METHODS: Among all stays unplanned in our department during the year 2004, we collected data about 8 blood biochemical markers (sodium, potassium, chloride, bicarbonate, anion gap, urea nitrogen, creatinin, proteins), performed between the day before and the day after admission. Mixed Cox regression models computed hazard ratios for mortality associated with biochemical markers concentration. The relationship between biochemical markers concentration and duration stay was investigated in mixed linear regression models. RESULTS: In 2004 our department totalized 1199 unplanned stays by 1054 distinct patients (age: 69.9+/-19.2 y, women: 59.2%), among which 59 deceased during stay. Biochemical markers were available for 977 (81.5%) stays (stay duration: 17.5+/-16.0 days). Inhospital mortality was significantly associated with plasma concentration on admission of potassium, proteins, anion gap and with urea nitrogen/creatinin ratio. Among survivors, duration stay was significantly associated with plasma concentration on admission of sodium, chlore, and anion gap. CONCLUSION: Biochemical markers performed on admission need particular attention as they provide immediate information about short term prognosis of internal medicine patients.

[Natural history of corticosteroid-induced lipodystrophy: a prospective follow-up of 37 patients]. / Histoire naturelle de la lipodystrophie cervicofaciale cortico-induite: suivi prospectif d'une cohorte de 37 patients.

PURPOSE: No data is available about the natural history of the corticosteroid-induced lipodystrophy. The purpose of this study is to describe the natural history of corticosteroid-induced lipodystrophy in a selected and homogenous population. METHODS: We conducted a cohort study between June 2003 and September 2005 and enrolled all consecutive patients starting long-term systemic corticosteroid therapy for giant cell arteritis (because of a standardized therapeutic schedule). After enrollment, patients were seen every month until the end of the corticosteroid therapy. After the drug withdrawal, they consulted every 3 months during 6 months. At each consultation, they were photographed in a standardized way. At the end of the study, the development of lipodystrophy was assessed by analyzing these photographs. We evaluated the incidence of corticosteroid-induced lipodystrophy during the course of giant cell arteritis therapy and the time between initiation of therapy and its apparition. Lastly, we evaluated the time between the prednisone withdrawal and the disappearance of lipodystrophy (or the mean prednisone dosage if the disappearance was observed under treatment). RESULTS: Thirty-seven patients were included (women: 73%; mean age: 75+/-7 years; mean initial daily prednisone dosage: 44+/-13 mg). The mean duration of follow-up was 23.6+/-7.4 months. Incidence of corticosteroid-induced lipodystrophy was 48% after 3 months and 60% after 12 months of therapy. The median time between treatment initiation and appearance of lipodystrophy was short (3 months [1-4]). During the decrease of the therapy or the 6 months following its end, we observed a regression of lipodystrophy in 71% of the patients. The median time between corticosteroids initiation and disappearance of lipodystrophy was 19 months [16-22] (concomitant median daily dosage of prednisone: 4 mg [0-7]). CONCLUSION: Lipodystrophy is frequently observed in corticosteroid-treated old patients. It appears precociously after the initiation of therapy and is usually reversible.

Severe strongyloidiasis in corticosteroid-treated patients.

Severe strongyloidiasis, caused by Strongyloides stercoralis, is a preventable life-threatening disease that can occur in any corticosteroid-treated patient who has travelled to a country with infested soil, even if the contact occurred up to 30 years previously. This diagnosis should be considered in corticosteroid-treated patients who experience either unusual gastrointestinal or pulmonary symptoms, or who suffer from unexplained sepsis caused by Gram-negative bacilli. Peripheral eosinophilia is not observed systematically and, even if present, is moderate in most cases. Ivermectine is the best prophylactic and therapeutic option, and thiabendazole should no longer be used. However, guidelines for the prevention and management of S. stercoralis infection in such patients have not yet been established.

Human leukocyte antigens and susceptibility to tuberculosis: a meta-analysis of case-control studies.

OBJECTIVE: To evaluate the association between human leukocyte antigens (HLA) of the major histocompatibility complex (MHC) and thoracic tuberculosis (TB) in immunocompetent adults. DESIGN: We searched Medline, Pascal, Pascal Biomed and Francis databases (all years) with the terms 'tuberculosis' and 'HLA'. Case-control studies were included that reported frequencies for the full range of antigens analysed by serological methods in healthy controls and adult patients not treated with glucocorticoids or immunosuppressive drugs, human immunodeficiency virus status negative or not reported, no debilitating chronic disease, and with a diagnosis of thoracic TB based on microbiological or histological criteria. Two authors independently abstracted the data and resolved disagreements by consensus. RESULTS: We summarised 60 HLA antigens reported in at least four of 22 studies totalling 1988 patients and 2897 controls. A lower risk of thoracic TB was found in carriers of B13 (OR 0.64, 95% CI 0.50-0.81, P < 0.0001), DR3 (OR 0.72, 95% CI 0.59-0.89, P = 0.002), and DR7 antigens (OR 0.65, 95% CI 0.53-0.80, P < 0.0001). Carriers of DR8 were at higher risk for thoracic TB (OR 1.72, 95% CI 1.21-2.46, P = 0.003). For these antigens, we found no significant heterogeneity between samples or evidence of publication bias. The risk of thoracic TB tended to be higher in carriers of DR2 (OR 1.67, 95% CI 1.16-2.41, P = 0.006), but the results were not consistent between studies (P value for heterogeneity < 0.0001). CONCLUSION: Susceptibility to TB is modulated by class I and II HLA antigens. However, these results based on the serological determination of antigens require confirmation by DNA-based methods to precisely identify those alleles involved.

Growth curves of anthropometric indices in a general population of French children and comparison with reference data.

BACKGROUND: The description of growth patterns of the different anthropometric measurements mainly used in epidemiological studies is useful to better understand the development of obesity in children and its consequences. OBJECTIVE: Our aim was to establish growth curves of anthropometric indices in a general population of French children born during the 1980s and to compare them with the French reference curves based on children born in the 1950s. DESIGN: As part of the Fleurbaix Laventie Ville Santé Studies I and II (FLVS), 441 girls and 467 boys were examined at least twice between 1993 and 2001. Height, weight and four skinfold thicknesses were measured. Body mass index (BMI), sum of peripheral and truncal skinfolds and truncal-to-peripheral ratio were calculated. Mean growth curves from ages 5 to 17 years were assessed for these indices, calculating means and 95% confidence interval per 1 year age group and by gender. RESULTS: Trajectories with age differed importantly according to the index considered; BMI was the one with the smallest difference between genders and the most linear shape with age. From the age of 5 years and after, the FLVS children were on average taller and had a higher subcutaneous adiposity than children born 30 years earlier. Truncal-to-peripheral ratio was higher in our population; this difference became more marked with puberty in girls. DISCUSSION: This study suggests the existence of a secular trend towards a precocious accelerated growth, and a more truncal adiposity distribution, especially in girls. It is a disquieting trend considering its expected consequences on adult health.
