Study of Body Composition by Biphotonic X-ray Absorptiometry in a Moroccan Female Population, an Indicator of Obesity?

INTRODUCTION: Our purpose was to study the body composition in a healthy female Moroccan adult group, and to help physicians to evaluate nutritional status. MATERIALS AND METHODS: Five hundred and nineteen healthy women aged from 20 to 80 years were included in the study. Bone mineral density at the hip and lumbar spine and the body composition parameters were measured by dual-energy X-ray absorptiometry: fat mass (FM), fat-free mass (FFM), and percentage (%) of body fat. The FFM index (FFMI) and the FM index (FMI) were calculated. We analyzed the population by age and body mass index (BMI) defined groups. RESULTS: The mean age of the population was 53.14 ± 13.69 years with an average BMI of 29.30 ± 5.04 kg/m2. Means of FM and FFM were 33.93 ± 9.18 kg and 36.91 ± 5 kg, respectively, with FM and FFMI of 13.65 ± 3.66 kg/m2 and 14.85 ± 1.91 kg/m2, respectively. The % FM, FFM, and their corresponding indices increased with age; a statistically significant difference was observed between the 20 and 39 age categories and the two other categories. The BMI category analysis showed that FFMI and FMI increased in obese women with a statistically significant difference between the four groups. Age and BMI were correlated significantly with the different parameters. CONCLUSION: This is the first Moroccan study to present body composition indexes in healthy Moroccan female adults. These reference values may be useful for the clinical evaluation of body composition and nutritional status.

Ces valeurs de référence peuvent être utiles pour l'évaluation clinique de la composition corporelle et de l'état nutritionnel.

Recommendations of the Moroccan Society of Rheumatology (SMR) for Diagnostic Management of Spondyloarthritis (SpA) and Psoriatic Arthritis (PsA).

In 2017, the Moroccan Society of Rheumatology (SMR) issued guidelines for the treatment of severe ankylosing spondylitis. The emergence of new therapeutic classes, the update of international guidelines for axial SpA and psoriatic arthritis, and the diagnostic and therapeutic challenges encountered by rheumatologists has led to the development of recent SMR guidelines for the management of SpA patients. A group-work included rheumatologists, specialists in physical medicine and rehabilitation, and epidemiologists from various sectors was tasked with writing these recommendations based on a literature review, then adapting them to the national context. Thus, 33 recommendations were selected and organized into two sections: diagnostic and therapeutic. The diagnostic section included three general principles and fourteen recommendations. The first, second, and third recommendations concerned the definition and diagnostic criteria for psoriatic arthritis and psoriatic arthritis. In the management of SpA, Recommendation 4 prioritized the importance of opportunity windows. The recommendation5 concerned the diagnostic and prognostic significance of HLAB27. The sixth and seventh recommendations related to imaging of the sacroiliac joints and the spine. The eighth recommendation focuses on the diagnosis and evaluation of perivascular thrombosis activity. The ninth and tenth recommendations concerned the evaluation of SpA activity and psoriatic arthritis. The eleventh and twelfth recommendations concern the evaluation of function and structural progression. The recommendation number thirteen concerned the diagnosis and treatment of coxitis. Recommendation 14 focuses on the most common co-morbidities and extra-rhinitological manifestations observed in SpA.

Recommendations of the Moroccan Society of Rheumatology (SMR) for the Therapeutic Management of Spondyloarthritis (SpA) including Psoriatic Arthritis (PsA).

The advent of new therapeutic classes and the updating of international recommendations have justified the development of recent recommendations by the Moroccan Society of Rheumatology. Methods Guidelines were drafted by a core steering committee after performing a literature search. A multidisciplinary task force, including three fellows, eleven rheumatologists, a specialist in physical medicine and rehabilitation, an epidemiologist from hospital-university, hospital and liberal sectors and one patient assessed the Best Practice Guidelines using 2 rounds of anonymous online voting by modified Delphi process. Thus, 19 recommendations were developed. Recommendation 1 concerns the therapeutic principles, recommendation 2 insists on the information and education of the patient, recommendation 3 concerns the general measures to be adopted, namely physical activity, smoking cessation and psychological support, recommendation 4 concerns Non-Steroidal Anti-Inflammatory Drugs which constitute the first-line treatment, recommendations 5 to 7 concern the use of analgesics, of general and local corticosteroid therapy and conventional synthetic disease-modifying antirheumatic drugs, recommendations 8 to 13 deal with the use of biologic agents, including new classes and their indications in radiographic and nonradiographic axial and peripheral spondyloarthritis, follow-up and management in case of failure or remission, recommendation 14 deals with the indication for Janus kinase inhibitors drugs, recommendation 15 deals with physical treatment and recommendation 16 deals with the indication of surgery. Recommendations 17 to 19 deal with special situations, namely fibromyalgia, vaccination and pregnancy. A well-defined therapeutic strategy with first- and second-line treatments has been established.

Characteristics of Late-Onset Spondyloarthritis: Data from the Moroccan Registry of Biological Therapies in Rheumatic Diseases.

Introduction The Assessment of SpondyloArthritis International Society (ASAS) criteria for axial and peripheral spondyloarthritis (SpA) allow for the classification of patients with an age of onset of disease of less than 45 years. However, SpA can start after this age. This study aimed to assess the characteristics of late-onset SpA (SpA>45 years) in the Moroccan registry of biological therapies in rheumatic diseases (RBSMR). Methods A cross-sectional study was conducted using the baseline data of the RBSMR. The protocol for the original RBSMR study was reviewed and approved by the Ethics Committee for Biomedical Research Mohammed V University - Rabat, Faculty of Medicine and Pharmacy of Rabat (approval number for the study was 958/09/19, and the date of approval was September 11, 2019), and all patients had given their written consent. Patients who met the 2009 ASAS criteria for SpA were included. They were divided into two groups: early-onset SpA (≤ 45 years) and late-onset SpA (>45 years). Clinical, biological, radiological, and therapy data of the two groups were compared. Statistical analysis was performed using SPSS v25 software (IBM Corp. Armonk, NY). Parameters with a p-value ≤0.05 were considered significant. Results Our population consisted of 194 patients. Thirty-one patients (16%) had late-onset SpA. Comparison between patients with early-onset (≤45 years) and late-onset SpA (>45 years) revealed that late-onset SpA had a higher tender joint count (p=0.01), a higher swollen joint count (p=0.02), depression (p=0.00), fibromyalgia (p=0.001), hypercholesterolemia (p=0.01), and a lower frequency of coxitis (p=0.008). Logistic regression analysis confirmed that late-onset SpA was associated with a higher tender joint count (OR=0.93, CI 95%: 0.88-0.98), a higher swollen joint count (OR=0.92, CI 95%: 0.85-0.99), depression ( OR=0.19, CI 95%:0.04-0.38), fibromyalgia (OR=1.75, CI 95%: 1.74-17.85), and a lower frequency of coxitis ( OR=0.29, CI 95%: 0.11-0.75). Conclusion As life expectancy increases, late-onset SpA will become increasingly common. It is therefore imperative to determine its characteristics. In the RBSMR study, late-onset SpA was associated with a high number of tender and swollen joints, depression, fibromyalgia, and a lower frequency of coxitis.

Epidemiology of monoclonal gammopathy in Morocco - A hospital-based study.

BACKGROUND: Monoclonal gammopathies are a group of disorders associated with clonal proliferation of plasma cells that produces a monoclonal protein. AIMS: The main objective of this study was to describe the epidemiological and immunochemical characteristics of monoclonal gammopathies diagnosed during 19 years in a Moroccan teaching hospital. MATERIALS AND RESULTS: This retrospective study enrolled 443 Moroccan patients with monoclonal gammopathy, patients meeting the inclusion and exclusion criteria in at the biochemistry department of Military Hospital in Rabat, the capital of Morocco, from January 2000 to August 2019. Of the 443 enrolled patients, 320 (72.23%) were men and 123 (27.77%) were women. All patients were of Caucasian origin, from 12 Moroccan regions. The patient's samples were collected and subjected to serum protein electrophoresis and serum immunofixation electrophoresis to further characterize the monoclonal protein. The mean ± SD age of the 443 participants was 62.24 ± 13.14 years. Reasons for being admitted to the hospital were as follows, bone pain (41.60%), renal failure (19.08%), alteration of the general condition (12.21%), and anemia (10.69). Plasma cell proliferative disorders in our study were as follows, multiple myeloma (MM) (45.65%), Monoclonal gammopathies of undetermined significance (MGUS) (39.05%), Waldenstrom's macroglobulinemia (5.58%), Lymphoma (2.27% + 1.2%), Chronic Lymphocytic Leukemia (2.48%), Plasma cell leukemia (1.86%), Plasmacytoma (0.62%), POEMS syndrome (0.41%), and Amyloidosis (0.84%). The most frequent isotypes in MM were the IgGκ (62) 36.5%, IgGλ (52) 30.6%, IgAκ (27) 15.9%, and the IgAλ (19) 11.2%. It is also worth noting that Free light chain MM represents 20% of all cases of MM. CONCLUSIONS: We found that monoclonal gammopathies are age-related and affects men more than women, also the results of this study point to the delayed diagnosis of monoclonal gammopathies, since most of our patients were diagnosed at the MM stage. The most frequent isotypes were the IgGκ and IgGλ in MM and MGUS, in Waldenström macroglobulinemia were IgMκ and IgMλ and the oligoclonal profile represented only 3.70%.

Shoulder capsulitis: What relation with diabetes mellitus in a moroccan population?

Introduction: Shoulder capsulitis (SC) is a common musculoskeletal complication in patients with diabetes. It can be particularly disabling. It is often overlooked by clinicians. The aim of this study is to evaluate the prevalence of retractile capsulitis and to identify the risk factors in a population of Moroccan diabetic patients. Materials and Methods: We realised a cross-sectional study including patients with diabetes mellitus (DM). We recorded the demographic and diabetic characteristics of our patients. SC and vascular complications were assessed by clinical and para-clinical investigations. The prevalence of SC was calculated. The factors associated with SC were evaluated by suitable statistical tests. Results: Three hundred and Sixty-five patients were included; 84.9% had Type 2 DM (T2DM). The mean age of the participants was 52.6 ± 13.6. Shoulder capsulitis was present in 12.6% of patients. In statistical analysis, age >50 years (P = 0.001), T2DM (P = 0.03), duration of progression >10 years (P = 0.03), dyslipidemia (P = 0.013) and macrovascular complications (P = 0.009) were associated with an increased frequency of SC. Conclusion: This study shows that the prevalence of SC is higher in diabetic patients. Therefore, inclusion of this pathology in the global management of the diabetic patient is necessary.

Résumé Introduction: la capsulite rétractile de l'épaule (CR) est une complication musculo-squelettique fréquente chez les patients diabétiques. Elle peut être particulièrement invalidante. Elle est souvent méconnue par les cliniciens. Cette étude a pour objectif d'évaluer la prévalence de la capsulite rétractile et d'identifier les facteurs de risque dans une population de patients diabétiques marocains. Methodes: Une étude transversale incluant des patients diabétiques. Nous avons enregistré les caractéristiques démographiques et les caractéristiques du diabète de nos patients. La CR et les complications vasculaires ont été évalués par des examens cliniques et para cliniques. La prévalence de la CR a été calculée, ensuite les facteurs associés à la CR ont été évalués par des tests statistiques adaptés. Resultat: 365 patients ont été inclus ; 84.9 % avaient un diabète de type 2. L'âge moyen des participants était de 52.6 ±13.6. Une capsulite de l'épaule était présente chez 12,6 % des patients. Dans l'analyse statistique, l'âge supérieur à 50 ans (P=0,001), le diabète de type 2 (P=0.03), la durée d'évolution >10 ans (P=0.03), la dyslipidémie (P=0.013) et les complications macro vasculaires (P=0.009) étaient associées à une fréquence accrue de la capsulite rétractile. Conclusion: cette étude montre que la prévalence de la CR est plus élevée chez les patients diabétiques. D'où la nécessité d'inclure cette pathologie dans la prise en charge globale du patient diabétique, et de la même manière, réaliser un dépistage de diabète chez les patients souffrant d'un capsulite rétractile. Mots clés: diabète sucré, complications musculo squelettiques, capsulite rétractile.

Cachexia Prevalence in a Population of Moroccan Women with Rheumatoid Arthritis.

Objective: To assess body composition in women with rheumatoid arthritis (RA) compared to healthy controls, to calculate the prevalence of rheumatoid Cachexia (RC), and to identify the associated factors. Methods: We conducted a case-control study on 112 female patients with RA according to the 2010 American College of Rheumatology/European League Against Rheumatism classification criteria for RA; and 224 age-matched healthy women. Body composition (BC) and bone mineral density (BMD) scans were obtained using Dual-energy X-ray absorptiometry (DXA). RC was defined by a fat-free mass index (FFMI) below the 10th percentile and a fat mass index (FMI) above the 25th percentile compared with the control group. We conducted a comparison between RA patients and healthy controls then a multiple regression analysis was conducted where the dependant variable is the presence of RC. Results: RC prevalence was 42.85% while the mean body mass index (BMI) was the same in both groups. RA patients had a higher FM and lower FFM comparing to healthy controls. In our population, 78.60% of patients were on methotrexate and 12.50% on anti TNF therapy. Comparison between patients with and without RC showed that patients with RC have a higher proportion of erosive arthritis and of active disease. Regression logistic analysis showed that RC was significantly associated to erosive arthritis and active disease (OR at 33.31 (8.42-131.70) and 8.98 (1.64-49.20) respectively), independently of age, erythrocyte sedimentation rate, C-reactive protein, disease duration, steroid cumulative dose and biologic Disease-Modifying Anti-Rheumatic Drugs(bDMARDs) use. Conclusion: Our study showed that almost half of our RA patients have RC, even with a high BMI.

Hodgkin Lymphoma Mimicking Lumbar Spine Tuberculosis.

INTRODUCTION: The clinical manifestations of Hodgkin lymphoma (HL) can closely mimic spine and lymph node tuberculosis (TB). Case Description. A 48-year-old man was initially treated for retroperitoneal lymph nodes TB, and this diagnosis was made without bacteriological and histopathological confirmation. After four months of regular therapy for TB, he did not improve and was admitted to our department for lumbar spine pain. We first made diagnosis of tuberculous spondylodiscitis, and anti-TB treatment was strengthened. But, after three weeks of hospitalization, his condition worsened clinically with onset of swelling of the left supraclavicular lymph node. So, after surgical excision and anatomopathological examination of the lymph node, the diagnosis of nodular sclerosis classic Hodgkin lymphoma was made. He was treated by chemotherapy, and his condition improved significantly after the first 2 cycles of chemotherapy. CONCLUSION: Repeated investigations may be helpful in establishing a correct diagnosis and starting an effective treatment in this highly curable disease.

Achilles Tendon Xanthoma and Cholestanol Revealing Cerebrotendinous Xanthomatosis: A New Case Report.

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive lipid storage disease rarely reported in Africa. Therefore, we report a Moroccan first case report of CTX. A 20-year-old woman was presented in our department for bilateral swelling of the posterior aspect of ankles and the anterior aspect knees with gait disturbances evolving since the age of 7. The patient was the first child of consanguineous marriage. She had bilateral cataracts and developmental delay. Laboratory findings revealed that the plasma cholestanol level was remarkably elevated, and plasma and urine bile alcohol levels were elevated. MRI of ankles showed a bilateral diffuse thickening of the Achilles tendon with hypointense in T1 and heterogeneous hypersignal in T2 with spots in hypersignal in T1 and T2. Brain MRI revealed bilateral and symmetrical T2 hypersignal of dentate nuclei, without white matter signal alterations or cerebral or cerebellar atrophy. A biopsy obtained of the Achilles swelling with a histological study showed an aspect of tendon xanthoma. Hence, the diagnosis of CTX was made. MRI, especially brain MRI, plays an important role in the diagnosis of CTX.

Does Rheumatoid Cachexia Predispose Patients with Rheumatoid Arthritis to Osteoporosis and Vertebral Fractures?

OBJECTIVE: To assess the prevalence and risk factors of rheumatoid cachexia (RC) and evaluate its relationship with osteoporosis and vertebral fractures (VF) in patients with rheumatoid arthritis (RA). METHODS: We enrolled into a cross-sectional study 178 consecutive patients with RA (82.6% women) with a mean age of 54.1 ± 11.5 years (25-82) and who fulfilled the American College of Rheumatology criteria for the classification of RA. Body composition, lateral VF assessment images, and scans of the lumbar spine and proximal femur were obtained using dual-energy x-ray absorptiometry. RC was defined by a fat-free mass index below the 10th percentile and a fat mass index above the 25th percentile compared with a reference population. VF were defined using Genant semiquantitative approach. RESULTS: RC was observed in 96 patients (53.9%) and osteoporosis in 52 patients (29.2%). Comparison between women with and without RC showed that women with RC had a longer disease duration, higher disease activity variables, higher steroid cumulative dose, and higher proportion of patients with erosive arthritis. Women with RC had lower total hip bone mineral density (BMD) and T score than women without RC, while comparison in men found only body mass index to be significantly lower in men with RC. Regression logistic analysis showed an independent and significant association between RC and age and disease activity in women. CONCLUSION: Our study showed that half of the patients with RA may have RC, a condition that was significantly associated with disease activity and low hip BMD, but not with VF.

Stevens-Johnson syndrome complicating adalimumab therapy in rheumatoid arthritis disease.

The efficacy of adalimumab, a fully human anti-tumor necrosis factor-α recombinant antibody, has dramatically improved the quality of life of patients with rheumatoid and psoriatic arthritis and Crohn's disease. Because it is fully human, one should not expect immune reactions to this molecule. Adverse reactions to adalimumab are limited mainly to injection site reactions and are very common. We, however, report a case of Stevens-Johnson syndrome that required hospitalization and cessation of adalimumab in a patient with rheumatoid arthritis (RA). In this case report, a 53-year-old woman with RA developed severe mucositis, peripheral rash and desquamation and fever concomitant with the fifth dose of 40 mg adalimumab. Infective etiologies were excluded. The patient responded rapidly to IV hydrocortisone and was able to be commenced on infliximab without recurrence of the Stevens-Johnson syndrome. Severe skin reactions induced by TNF-α antagonists can be very serious, and prescribers need to be aware of the potential for the mucocutaneous adverse effects from the use of these agents, particularly due to the significant morbidity and mortality that are associated with SJS.

Prevalence and Risk Factors of Discordance between Left- and Right-Hip Bone Mineral Density Using DXA.

To determine the prevalence of significant left-right differences in hip bone mineral density (BMD), and the impact of this difference on osteoporosis diagnosis, we measured bilateral proximal femora using dual energy X-ray absorptiometry (DXA) in 3481 subjects (608 males, 2873 females). The difference between left and right hip was considered significant if it exceeded the smallest detectable difference (SDD) for any of the three hip subregions. Contralateral femoral BMD was highly correlated at all measuring sites (r = 0.92-0.95). However, significant left-right differences in BMD were common: the difference exceeded the SDD for 54% of patients at total hip, 52.1% at femoral neck, and 57.7% at trochanter. The prevalence of left-right differences was greater in participants >65 years. For 1169 participants with normal spines, 22 (1.9%) had discordant left-right hips in which one hip was osteoporotic; for 1349 patients with osteopenic spines, 94 (7%) had osteoporosis in one hip. Participants with BMI < 20 kg/m(2) were more likely to show major T-score discordance (osteoporosis in one hip and normal BMD in the other). Multiple regression analysis showed that the only significant statically parameter that persists after adjusting for all potential confounding parameters were age over 65 years.

Relationship between vertebral fracture prevalence and abdominal aortic calcification in men.

OBJECTIVE: To study the relationship between the prevalence of vertebral fractures (VFs) using VF assessment (VFA) in asymptomatic men and the prevalence and severity of abdominal aortic calcification (AAC). METHODS: We enrolled 709 men with mean (s.d.) age 62.4 (8.6) (range 45-89) years. Lateral VFA images and scans of the lumbar spine and proximal femur were obtained using a GE Healthcare Lunar Prodigy densitometer. VFs were defined using a combination of the Genant semi-quantitative (SQ) approach and morphometry. VFA images were scored for AAC using a validated 24-point scale. RESULTS: VFA images showed that 68 (14.2%) of the participants had at least one grade 2/3 VF, 82% did not have any detectable AAC, whereas the prevalence of significant atherosclerotic burden, defined as an AAC score of ≥5, was 2.8%. The group of men with grade 2/3 VFs had a statistically significant higher AAC score and higher proportion of subjects with extended AAC, and lower weight, height and lumbar spine and hip BMD and T-scores than those without a VFA-identified VF. Multiple regression analysis showed that the presence of grade 2/3 VFs was significantly associated with BMI [odds ratio (OR 0.915; 95% CI 0.589, 0.975; P = 0.006], AAC score ≥5 (OR 4.509; 95% CI 1.505, 13.504; P = 0.007) and osteoporosis in any site (OR 5.159; 95% CI 3.116, 8.540; P ≤ 0.0001). CONCLUSION: In elderly men, extended AAC is an indicator of the increased risk for prevalent VFs regardless of age, BMI, history of fractures, smoking and BMD.

Hypovitaminosis D and prevalent asymptomatic vertebral fractures in Moroccan postmenopausal women.

BACKGROUND: Hypovitaminosis D is associated to accentuated bone loss. However, association between osteoporotic vertebral fractures (VFs) and vitamin D status has not been clearly established. OBJECTIVE: To determine serum vitamin D status and to assess the association of vitamin D status with bone mineral density (BMD) and asymptomatic VFs prevalence using vertebral fracture assessment (VFA) in a cohort of Moroccan menopausal women. METHODS: from June to September 2010, 178 menopausal women 50 years old and over were enrolled in this cross-sectional study. The mean ± SD (range) age, weight, height and BMI were 58.8 ± 8.2 (50 to 79) years, 73.2 ± 13.8 (35 to 119) Kgs, 1.56 ± 0.06 (1.43 - 1.79) m and 29.8 ± 5.9 (17.5 - 49.8) kg/m2, respectively. VFA images and scans of the lumbar spine and proximal femur were obtained using a GE Healthcare Lunar Prodigy densitometer. VFs were defined using a combination of Genant semiquantitative approach and morphometry. Serum levels of 25-hydroxyvitamin D (25(OH)D) were measured. RESULTS: Among the 178 women, 45 (25.2%) had densitometric osteoporosis, and on VFA, VFs (grade 2 or 3) were detected in 20.2% while grade 1 were identified in 33.1%. The mean values of serum levels of 25(OH)D were 15.8 ± 11.6 ng/ml (range: 3.0 - 49.1) with 152 patients (85.3%) having levels <30 ng/ml (insufficiency) and 92 (51.6%) <10 ng/ml (deficiency). Stepwise regression analysis showed that presence of VFs was independently related to age, 25(OH)D and densitometric osteoporosis. CONCLUSION: our study shows that advanced age, hypovitaminosis D and osteoporosis are independent risk factors for asymptomatic VFs in Moroccan postmenopausal women.

Homocysteine, folate, and vitamin B12 levels and vertebral fracture risk in postmenopausal women.

The objective of this study was to examine the influence of homocysteine, vitamin B(12), and folate on the prevalence of asymptomatic osteoporotic vertebral fractures (VFs) using vertebral fracture assessment (VFA) in postmenopausal women. The study cohort consisted of 188 consecutive postmenopausal women (mean age, weight, and body mass index of 57.9 ± 8.5 [41-91]yr, 74.4 ± 13.5 [38-150]kg, and 30.4 ± 5.2 [17.1-50.7]kg/m(2), respectively). Lateral VFA images and scans of the lumbar spine and proximal femur were obtained using a Lunar Prodigy Vision densitometer (GE Healthcare Inc., Waukesha, WI). VFs were defined using a combination of Genant's semiquantitative approach and morphometry. Fifty-eight (30.9%) patients had densitometric osteoporosis. VFs were identified using VFA in 76 (40.4%) patients: 61 women had grade 1 VFs and 15 had grade 2 or 3 VFs. No statistical difference was shown between the 3 groups (absence of VFs, VFs grade 1, and VFs grade 2/3) concerning the biological parameters. Comparison of patients according to quartiles of homocysteine levels showed that women in the highest quartile were older and had a lower bone mineral density (BMD); however, the prevalence of VFs was not statistically different from that of women in the other quartile groups. Stepwise regression analysis showed that homocysteine was not independently associated with the presence of VFs, which was mainly related to the osteoporotic status. Although a weak association was observed between hyperhomocysteinemia and low BMD and a trend to higher prevalence of grade 2/3 VFs was observed, our study did not confirm that homocysteine, vitamin B(12), and folate status are important determinants of prevalent asymptomatic VFs in postmenopausal women.

The relationship between sex steroids, bone turnover and vertebral fracture prevalence in asymptomatic men.

OBJECTIVE: To examine the association between oestradiol (E2), testosterone (T), SHBG levels and vertebral fractures' (VFs) prevalence in asymptomatic men. METHODS: The study cohort consists of a population of 112 consecutive men (mean±SD (range) age, weight and BMI were 62.9±9.2 (41-84) years, 75.0±13.8 (45-120) kgs and 26.4±4.7 (18.0-39.6) kg/m(2), respectively). Lateral vertebral fracture assessment (VFA) images and scans of the lumbar spine and proximal femur were obtained using a GE Healthcare Lunar Prodigy densitometer. VFs were defined using a combination of Genant semiquantitative approach and morphometry. Serum levels of T, E2, CTx and osteocalcine were measured. Free androgen index (FAI) and free estradiol index (FEI) were calculated respectively from the ratio of serum T and E2 to SHBG. RESULTS: Among the 112 men, 38 (33.9%) had densitometric osteoporosis, and on VFA, VFs were identified in 60 (53.5%): 24 men had grade 1 and 36 had grade 2 or 3 VFs (32.1%). Men with VFs weighted less and had a statistically significant lower lumbar spine and total hip BMD and T-scores than those without a VFA-identified vertebral fracture. Levels of osteocalcine, CTx, and SHBG were statistically higher in men with grades 2 and 3 VFs than men with grade 1 VFs and those without VFs whereas FAI and FEI levels were significantly lower. Comparison of patients according to quartiles of SHBG levels showed that men in the highest quartile were older, had a lower lumbar spine and total hip BMD and a higher prevalence of osteoporosis and VFs. They had also higher levels of CTx. Stepwise regression analysis showed that the osteoporotic status and SHBG was independently associated to the presence of VFs. CONCLUSION: Men with asymptomatic densitometric VFs have lower BMD than subjects without VFs. They have evidence of higher SHBG levels and hence lower free sex steroids as well as increased bone resorption. This study confirms that BMD and CTx are the most important determinant of asymptomatic VFs, and that SHBG is an independent risk factor that must be taken into account.

Prevalence and risk factors of vertebral fractures in women with rheumatoid arthritis using vertebral fracture assessment.

OBJECTIVE: To study the prevalence and risk factors of vertebral fractures (VFs) in a large cohort of patients with RA using VF assessment (VFA). METHODS: We enrolled 172 women with RA, none of whom were taking osteoporosis medications. Patients underwent dual X-ray absorptiometry at the hip and spine and VFA, and completed a questionnaire. Radiological status was assessed by the modified Sharp erosion and narrowing score. VFA was classified using a combination of Genant semi-quantitative approach and morphometry. RESULTS: Patients had a mean (s.d.) disease duration of 8.4 (5.2) years. VFs were detected in 36% (62/172). This group of women had a statistically significant lower weight, height and lumbar spine and total hip BMD and T-scores than those without a VFA-identified VF. They also had more long-standing and severe disease and a greater consumption of corticosteroids. Stepwise regression analysis showed that the presence of VFs was independently associated with low weight and total hip T-score and long disease duration, CRP and Sharp erosion score. CONCLUSION: RA is a risk factor on its own for the development of osteoporosis and VFs and this risk increases more with low weight, disease duration and severe course of disease. These findings may suggest that to prevent the development of VFs, precautions should be taken immediately to suppress the disease activity and correct the weight loss in patients with RA.

Erdheim-Chester disease: a case report with pulmonary, kidney involvement and bone lesions.

We report the case of a 42-year-old woman who was admitted in 2002 for exploration of diffuse bone pain. She had medical history of pulmonary tuberculosis. Her current symptoms had started 9 months earlier and consisted of bone pain, affecting the legs. She had asthenia and weight loss. At admission, physical examination showed bilateral and symmetrical long bone pain, especially the knees and the ankles. Physical exam was normal elsewhere. Laboratory tests showed inflammation, with an erythrocyte sedimentation rate of 90 mm/h and C-reactive protein 8 mg/l. Protein electrophoresis, red and white blood cell count, renal, and liver function tests were normal. Serum calcium, phosphorus, and urinary calcium were normal. Radiographs showed multiple mixed bone lesions with sclerotic and lytic areas of the femora, tibiae, humerus. Chest radiographs and thoracic computed tomography (CT) scan showed pulmonary fibrosis. Biopsy of the tibial area displayed foamy lipid-laden histiocytes, confirming the diagnosis of Erdheim-Chester disease. Patient was treated with prednisolone plus cyclophosphamide. Her clinical condition improved remarkably during 4 years, but she developed acute renal failure leading to death.
