Impact of previous glucocorticoid therapy on diagnostic accuracy of [18F] FDG PET-CT in giant cell arteritis.

OBJECTIVE: To evaluate the impact of prior glucocorticoid (GC) treatment on the diagnostic accuracy of 18F-FDG PET-CT in giant cell arteritis (GCA). METHODS: Retrospective study of a consecutive cohort of 85 patients with proven GCA who received high-dose GC before PET-CT. RESULTS: Thirty-nine patients previously treated with methylprednisolone (MP) boluses, of whom 37% were PET-CT (uptakes grade 3 or 2) positive. The positivity rate was 80% with MP doses of 125 mg, 33% with 250 or 500 mg, and 0% with doses of 1 g.  If we also classify as positive those cases with a grade 1 uptake (with a circumferencial uptake and smooth linear or long segmental pattern, possibly indicative of "apparently inactive" vasculitis), the positivity rate increases to 62% (100%, 50-60%, and 33% for the different MP doses, respectively). In patients with new-onset GCA treated with high-dose oral GC, PET-CT positivity was 54.5% in patients treated for less than two weeks, 38.5% in those treated for 2 to 4 weeks, and 25% in those treated for 4 to 6 weeks (increasing to 91%, 77%, and 50%, respectively, if we include cases with grade 1 uptake and these characteristics). In patients with relapsing/refractory GCA, or who developed GCA having a prior history of PMR, PET-CT positivity reached 54% despite long-term treatment with low-to-moderate doses of GC (68% including cases with a grade 1 uptake). CONCLUSION: A late 18F-FDG PET-CT (beyond the first 10 days of treatment) can also be informative in a considerable percentage of cases.

A prospective study of lung disease in a cohort of early rheumatoid arthritis patients.

Lung disease is common in patients with rheumatoid arthritis (RA). The onset of lung involvement in RA is not well known. The objective is to describe the features and evolution of lung involvement in early RA, its relationship with disease activity parameters, smoking and treatments. Consecutive patients with early RA without respiratory symptoms were included and tracked for 5 years. Lung assessment included clinical, radiological and pulmonary function tests at diagnosis and during follow-up. Peripheral blood parameters (erythrocyte sedimentation rate, C reactive protein, rheumatoid factor and anti-citrullinated peptide autoantibodies) and scales of articular involvement, such as DAS28-CRP, were evaluated. 40 patients were included and 32 completed the 5-year follow up. 13 patients presented lung involvement in the initial 5 years after RA diagnosis, 3 of them interstitial lung disease. Significant decrease of diffusion lung transfer capacity of carbon monoxide over time was observed in six patients, 2 of them developed interstitial lung disease. DLCO decrease was correlated with higher values of CRP and ESR at diagnosis. Methotrexate was not associated with DLCO deterioration or lung disease development. Subclinical progressive lung disease correlates with RA activity parameters. Smoking status and methotrexate were not associated with development or progression of lung disease.

Rheumatic immune-related adverse events in patients on anti-PD-1 inhibitors: Fasciitis with myositis syndrome as a new complication of immunotherapy.

OBJECTIVE: To evaluate the prevalence and type of rheumatic immune-related adverse events (IRAEs) in patients receiving programmed cell death protein-1 (PD-1) inhibitors. METHODS: This is a single-center prospective observational study, including all cancer patients receiving PD-1 inhibitors between January 2016 and January 2018. RESULTS: During the period analyzed, we evaluated a total of 11 patients. No patient had pre-existing rheumatic or autoimmune disease. In this period, a total of 220 patients were treated with PD1 inhibitors in our center; therefore, the estimated minimum prevalence of rheumatic IRAEs related to these therapies in our population was 5%. The rheumatic IRAEs evaluated included 5 cases of oligo- or polyarthritis, 1 with a polymialgia rheumatica-type syndrome, 2 cases of immunotherapy-induced sicca syndrome, 2 patients who presented symptomatic inflammatory myositis with fasciitis in lower extremities, and 1 patient with a paraneoplastic acral vascular syndrome. The median time to IRAE after anti-PD1 exposure was 8 weeks (range: 2-24). In 5 patients, immunotherapy was discontinued (due to the adverse effect in three and cancer progression in two). In general terms the symptoms resolved completely with symptomatic treatment. Disease-modifying antirheumatic drugs were needed for 2 patients. CONCLUSION: Rheumatic IRAEs should be kept in mind during the follow-up and evaluation of patients treated with PD-1 inhibitors. The concomitant development of symptomatic inflammatory myositis with fasciitis in lower extremities appears to be a new adverse effect of anti-PD-1 immunotherapy. Additional studies are needed to determine how to adequately control and manage these complications.

Spanish consensus on treat to target for osteoporosis.

To reach a Spanish expert consensus on a treat-to-target strategy in osteoporosis, a Delphi Consensus Study has been developed. Most of the experts (59.8%) were rheumatologist with a mean clinical experience of 21.3 years (SD 8.5). Consensus was achieved for 70% of the items. Therapeutic objectives, patient follow-up scheme, treatment failure criteria, and appropriate treatment choice for use in T2T strategy in Spain have been defined. INTRODUCTION: The paper aims to achieve a Spanish expert consensus on a treat-to-target (T2T) strategy in osteoporosis. METHODS: A scientific committee led the project and was involved in expert panel identification and Delphi questionnaire development. Two Delphi rounds were completed. The first-round questionnaire included 24 items and assessed, using a seven-point Likert scale, the experts' wish (W) and prognosis (P) in 5 years for each topic (applicability, therapeutic objectives, patient follow-up, and possible treatment to be prescribed). Items for which there was no consensus in the first round were included in the second round. Consensus was defined as ≥75% agreement (somewhat/mostly/entirely agree) or disagreement (somewhat/mostly/entirely disagree) responses. RESULTS: Of the experts, 112 and 106 completed the first and second rounds, respectively. 59.8% were rheumatologists with a mean clinical experience of 21.3 years (SD 8.5). Consensus was achieved for 70% of the items, and was established regarding the utility of a T2T strategy to define therapeutic objectives, optimal follow-up, and therapeutic algorithm. Participants agreed on the utility of the bone mineral density (BMD) value (T-score >-2.5 SD for spine and >-2.5/-2.0 SD for femoral neck), lack of fractures, and fracture risk (FRAX) as therapeutic objectives. For measuring BMD changes, consensus was achieved on the suitability of hip and femoral neck locations. Experts agreed to consider treatment failure as when a significant BMD gain could not be achieved, or when a new fracture occurs within 2-3 years. There was consensus that all proposed therapies should achieve a therapeutic target through T2T strategy (treatments with the highest consensus scores were denosumab and teriparatide). CONCLUSION: The therapeutic objectives, patient follow-up scheme, treatment failure criteria, and appropriate treatment choice for use in T2T strategy in Spain have been established by a panel of experts. Some aspects nevertheless still require further analysis.

The global burden attributable to low bone mineral density.

INTRODUCTION: The Global Burden of Disease Study 2010 estimated the worldwide health burden of 291 diseases and injuries and 67 risk factors by calculating disability-adjusted life years (DALYs). Osteoporosis was not considered as a disease, and bone mineral density (BMD) was analysed as a risk factor for fractures, which formed part of the health burden due to falls. OBJECTIVES: To calculate (1) the global distribution of BMD, (2) its population attributable fraction (PAF) for fractures and subsequently for falls, and (3) the number of DALYs due to BMD. METHODS: A systematic review was performed seeking population-based studies in which BMD was measured by dual-energy X-ray absorptiometry at the femoral neck in people aged 50 years and over. Age- and sex-specific mean ± SD BMD values (g/cm(2)) were extracted from eligible studies. Comparative risk assessment methodology was used to calculate PAFs of BMD for fractures. The theoretical minimum risk exposure distribution was estimated as the age- and sex-specific 90th centile from the Third National Health and Nutrition Examination Survey (NHANES III). Relative risks of fractures were obtained from a previous meta-analysis. Hospital data were used to calculate the fraction of the health burden of falls that was due to fractures. RESULTS: Global deaths and DALYs attributable to low BMD increased from 103 000 and 3 125 000 in 1990 to 188 000 and 5 216 000 in 2010, respectively. The percentage of low BMD in the total global burden almost doubled from 1990 (0.12%) to 2010 (0.21%). Around one-third of falls-related deaths were attributable to low BMD. CONCLUSIONS: Low BMD is responsible for a growing global health burden, only partially representative of the real burden of osteoporosis.

Streptococcal vertebral osteomyelitis: multiple faces of the same disease.

The role of Streptococcus species as an aetiological microorganism of vertebral osteomyelitis (VO) is considered to be of little relevance. We aimed to describe a large number of cases of streptococcal vertebral osteomyelitis (SVO), to analyze the clinical features associated with different Streptococcus species, and to compare them with a cohort of patients with VO caused by Staphylococcus aureus. An incidence study and a retrospective, multicenter, observational clinical study of cases of SVO (1991-2011) were performed. Statistical comparison of SVO by different species and between them and staphylococcal VO was carried out. Over the whole period there was an increasing incidence in the number of VOs and SVOs per year (p <0.05). Among 58 cases of SVO, those caused by non-viridans streptococcus (Streptococcus pneumoniae, Streptococcus agalactiae and Streptococcus pyogenes; n = 26) mimicked VO by S. aureus, and presented with more fever, neurological symptoms and paravertebral abscesses in comparison with those caused by the viridans group (remaining species). In contrast, the latter have a sub-acute clinical picture and were associated with the presence of endocarditis (p <0.05). Among non-viridans SVOs, concomitant infection was specifically related to S. pneumoniae (p <0.05). In conclusion, SVO presents a wide range of clinical patterns. The relationship between VO and diagnosis of endocarditis was established with SVO caused by the viridans group. Whereas non-viridans SVO mimics acute characteristics of VO caused by S. aureus, cases of viridans SVO are significantly more likely to have a sub-acute clinical presentation. The increased incidence of SVO during the last decades could support a new epidemiological scenario.

Early changes in biochemical markers of bone formation during teriparatide therapy correlate with improvements in vertebral strength in men with glucocorticoid-induced osteoporosis.

UNLABELLED: Changes of the bone formation marker PINP correlated positively with improvements in vertebral strength in men with glucocorticoid-induced osteoporosis (GIO) who received 18-month treatment with teriparatide, but not with risedronate. These results support the use of PINP as a surrogate marker of bone strength in GIO patients treated with teriparatide. INTRODUCTION: To investigate the correlations between biochemical markers of bone turnover and vertebral strength estimated by finite element analysis (FEA) in men with GIO. METHODS: A total of 92 men with GIO were included in an 18-month, randomized, open-label trial of teriparatide (20 µg/day, n = 45) and risedronate (35 mg/week, n = 47). High-resolution quantitative computed tomography images of the 12th thoracic vertebra obtained at baseline, 6 and 18 months were converted into digital nonlinear FE models and subjected to anterior bending, axial compression and torsion. Stiffness and strength were computed for each model and loading mode. Serum biochemical markers of bone formation (amino-terminal-propeptide of type I collagen [PINP]) and bone resorption (type I collagen cross-linked C-telopeptide degradation fragments [CTx]) were measured at baseline, 3 months, 6 months and 18 months. A mixed-model of repeated measures analysed changes from baseline and between-group differences. Spearman correlations assessed the relationship between changes from baseline of bone markers with FEA variables. RESULTS: PINP and CTx levels increased in the teriparatide group and decreased in the risedronate group. FEA-derived parameters increased in both groups, but were significantly higher at 18 months in the teriparatide group. Significant positive correlations were found between changes from baseline of PINP at 3, 6 and 18 months with changes in FE strength in the teriparatide-treated group, but not in the risedronate group. CONCLUSIONS: Positive correlations between changes in a biochemical marker of bone formation and improvement of biomechanical properties support the use of PINP as a surrogate marker of bone strength in teriparatide-treated GIO patients.

Arthritis related to systemic meningococcal disease: 34 years' experience.

The purpose of this investigation was to assess the clinical characteristics, therapeutic aspects, and outcome of arthritis related to invasive meningococcal disease (IMD). All episodes of bacterial meningitis and IMD are recorded systematically. We selected all episodes of IMD, with or without meningitis, that presented arthritis. From 1977 to 2010, 522 episodes of IMD were treated. Thirty-nine of these (7.5 %, 26 women, mean age 33 years) presented arthritis. Of these 39, 37 (95 %) presented skin lesions and 31 (79 %) had meningitis. Twenty (51 %) had positive blood cultures and six (15 %) had shock. No differences were found in skin lesions, shock, or bacteremia compared to cases without arthritis. In contrast to other septic forms, arthritis related to IMD was cured with short antibiotic therapy and without surgical drainage. There was no mortality. All patients recovered and none presented joint sequelae; however, 13 adult patients (33 %) required long-term treatment with steroids due to persistent symptoms. Arthritis related to IMD most frequently affects the knees and ankles, and may be a cause of fever relapse. Short antibiotic therapy is enough in all cases and surgical drainage is not needed. In some adult patients, especially those over 50 years of age, evolution is torpid and steroid therapy may be required in order to achieve recovery.

Adult onset Still's disease: review of 41 cases.

OBJECTIVES: To describe the clinical, laboratory and radiological features, treatment and prognosis of patients with adult onset Still's disease (AOSD). METHODS: Specific clinical features were retrospectively recorded in 41 patients fulfilling the Yamaguchi criteria. Patients were reviewed in two academic hospitals with a referral area of 700,000-1,000,000 inhabitants. Laboratory tests including haemogram, ferritin, biochemistry and autoimmunity were reviewed. Radiological studies, treatment and ACR functional class were determined. RESULTS: Forty-one patients with AOSD were identified, 25 of whom were female. Mean age at diagnosis: 38.19 years (range 17-68). Feverish polyarthritis was the most common clinical presentation. Acute phase reactants were invariably high in all patients. Serum ferritin levels were elevated in 86% of patients. Anti-cyclic citrullinated peptide antibodies (anti-CCP antibodies) were negative in all patients except one. The course of the disease was monocyclic in 44% of the patients, polycyclic in 26%, and chronic articular in 30%. ACR class was as follows: 29 (72.5%) class I, 7 (17.5%) class II, 2 (5%) class III and 2 (5%) class IV. As for the treatment received, aspirin or NSAIDs controlled the disease in eight patients (19.5%) and high-dose corticosteroids (0.5-1 mg/kg/day) in 32 (78%). Almost half of the patients (49%) required an additional diseasemodifying agent, usually methotrexate. Finally, in seven of them (17%) a biological treatment with TNF-α or specially anti-IL-1 had to be added to control the disease. CONCLUSIONS: The clinical and laboratory findings were similar to previous studies. Anti-CCP antibodies were almost always negative. A monocyclic course was associated with a good prognosis. Most of the patients were in ACR functional class I and II. Biological agents were required in 7 patients (17%).

Cervical spine involvement in rheumatoid arthritis: correlation between neurological manifestations and magnetic resonance imaging findings.

OBJECTIVE: To evaluate the correlation between neurological deficits indicative of compressive myelopathy and MRI findings in a series of patients with RA and symptomatic involvement of the cervical spine. METHODS: Forty-one consecutive patients with RA were studied using cervical spine MRI. Unconditional logistic regression analysis was used to identify MRI parameters of cervical spine involvement associated with the development of neurological dysfunction. RESULTS: The mean age of the 41 patients (33 women and 8 men) was 59 yrs (range 23-82 yrs), while the median disease duration was 18 +/- 9 yrs (range 4-40 yrs). According to Ranawat's classification, 17 (42%) patients were in Class I, 21 (51%) in Class II and 3 (7%) in Class III. Thus, patients with clinical manifestations of compressive myelopathy (Ranawat's Class II + III) represented 58% (24/41) of all cases. Among the different MRI parameters of cervical spine involvement analysed, only the presence of atlantoaxial spinal canal stenosis [odds ratio (OR) 4.55; 95% CI 1.14-18.15], atlantoaxial cervical cord compression (OR 9.6; 95% CI 1.08-85.16) and subaxial myelopathy changes (OR 11.43; 95% CI 1.3-100.81) were associated with a significantly increased risk for neurological dysfunction (Ranawat's Class II or III). CONCLUSION: In RA patients with symptomatic cervical spine involvement, there is a strong correlation between the development of neurological dysfunction and MRI identification of atlantoaxial spinal canal stenosis, especially in those cases with evidence of upper cervical cord or brainstem compression and subaxial myelopathy changes.

Impact of antiplatelet therapy in the development of severe ischemic complications and in the outcome of patients with giant cell arteritis.

OBJECTIVE: To evaluate whether concomitant treatment with low-dose aspirin or other antiplatelet agents have an impact on the risk of severe ischemic complications and in the outcome of patients with giant cell arteritis (GCA). METHODS: A retrospective follow-up study of an unselected population of 121 patients with GCA. RESULTS: Thirty-seven patients (30.5%) received antiplatelet therapy before the onset of GCA symptoms and continued taking it during the corticosteroid treatment (30 received aspirin and 7 other antiplatelet agents). No statistically significant reduction in the incidence of ischemic manifestations (including jaw claudication, visual manifestations, cerebrovascular accidents, ischemic heart disease, and limb claudication due to large artery stenosis) was observed in this group compared with the remaining patients. When we analyzed follow-up data, we found no significant differences between groups in terms of frequency of relapses and percentage of patients recovered from GCA. Corticosteroid requirements among patients in long-lasting remission were lower in those under antiplatelet therapy, but this reduction was fairly modest, statistically non significant and thus of uncertain clinical significance. Similar results were found when only aspirin exposed patients (n=30) were compared to non-exposed patients. Logistic regression analysis showed that antiplatelet therapy (p=0.54, OR 1.31; 95% CI: 0.54-3.19) had not an independent protective effect against ischemic events when adjusted for age, sex, and the presence of atherosclerotic risk factors. CONCLUSION: We did not observe a significant benefit derived from the use of antiplatelet therapy in either the incidence of severe ischemic events or the disease outcome. Although our results do not discard a potential therapeutic effect of high-dose aspirin, they do not confirm its suggested protective effect in preventing ischemic complications when used at antiplatelet doses.

High HDL-cholesterol in women with rheumatoid arthritis on low-dose glucocorticoid therapy.

BACKGROUND: Dyslipidaemia has been described in non-treated rheumatoid arthritis (RA), and improves after therapy with disease modifying anti-rheumatic drugs or glucocorticoids; however, it has generally been perceived that glucocorticoids adversely affect lipid metabolism. The association of low dose glucocorticoid therapy with plasma lipid levels was evaluated in female RA patients. MATERIALS AND METHODS: A cross-sectional study was conducted in 78 female RA patients [mean age: 60 (12) years; mean disease duration: 13 (9) years]. Sixty-five (83%) were on glucocorticoid therapy [total equivalent mean prednisone dose: 5.1 (1.7) mg d(-1)]. Each patient was assessed through a self-reported questionnaire, structured interview and physical examination. Blood samples were obtained for routine biochemistry, lipid profile and haematological tests. Lipid profiles of RA patients who were and were not on glucocorticoid therapy were compared. RESULTS: Clinical and laboratory features of the two groups of patients were similar, except for the Health Assessment Questionnaire and body mass index, which were significantly higher in the patients on glucocorticoid therapy. These patients had 14.7% higher serum high-density lipoprotein cholesterol (HDL-c) levels than untreated patients (P = 0.043), mainly at the expense of HDL2 subfraction, which was 24.4% higher (P < 0.039), whereas HDL3-c was only 7.4% higher (P = 0.219). Serum levels of glucose and total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL -c), very low-density lipoprotein cholesterol, apolipoproteins A-I and B were not increased in patients on glucocorticoid therapy. CONCLUSIONS: Low dose glucocorticoid therapy in RA patients is associated with an increase in HDL-c, without increasing LDL-c or triglyceride. These lipid changes may overall be considered favourable.

[Sensitization to Castanea sativa pollen and pollinosis in northern Extremadura (Spain)]. / Sensibilización a polen de castaño y polinosis en el norte de Extremadura.

BACKGROUND: Castanea sativa pollen allergy has generally been considered to be uncommon and clinically insignificant. In our geographical area (Plasencia, Cáceres, Spain) Castanea sativa pollen is a major pollen. OBJECTIVE: To determine the atmospheric fluctuations and prevalence of patients sensitized to Castanea pollen in our region and to compare this sensitization with sensitizations to other pollens. METHODS: Patients with respiratory symptoms attending our outpatient clinic for the first time in 2003 were studied. The patients underwent skin prick tests with commercial extracts of a battery of inhalants including Castanea sativa pollen. Serologic specific IgE to Castanea sativa pollen was determined using the CAP system (Pharmacia and Upjohn, Uppsala, Sweden). Airborne pollen counts in our city were obtained using Cour collection apparatus over a 4-year period (2000 to 2003). RESULTS: The most predominant pollens detected were (mean of the maximal weekly concentrations over 4 years in pollen grains/m3): Quercus 968, Poacea 660, Olea 325, Platanus 229, Pinus 126, Cupresaceae 117, Plantago 109, Alnus 41, Populus 40, Castanea 32. We studied 346 patients (mean age: 24.1 years). In 210 patients with a diagnosis of pollinosis, the percentages of sensitization were: Dactylis glomerata 80.4%, Olea europea 71.9%, Fraxinus excelsior 68%, Plantago lanceolata 62.8%, Chenopodium album 60.9%, Robinia pseudoacacia 49%, Artemisia vulgaris 43.8%, Platanus acerifolia 36.6%, Parietaria judaica 36.1%, Populus nigra 32.3%, Betula alba 27.6%, Quercus ilex 21.4%, Alnus glutinosa 20.9%, Cupressus arizonica 7.6% and Castanea sativa 7.1%. Fifteen patients were sensitized to Castanea sativa and 14 had seasonal rhinoconjunctivitis and asthma. Ten patients had serum specific IgE to Castanea pollen (maximum value: 17.4 Ku/l). Castanea pollen is present in our area in large amounts from the 23rd to the 28th weeks of the year, with a peak pollen count in the 25th week. CONCLUSIONS: The most important allergenic pollens in northern Extremadura were Poaceae, Olea europaea and Plantago sp. The prevalence of sensitization to Castanea sativa pollen was very low (7.1%). Most sensitized patients had asthma and polysensitization. Castanea sativa pollen is not a major cause of pollinosis in our area.

Giant cell arteritis and polymyalgia rheumatica: usefulness of vascular magnetic resonance imaging studies in the diagnosis of aortitis.

OBJECTIVES: One of the unresolved challenges posed in giant cell (temporal) arteritis (GCA) is the detection and monitoring of large-artery complications, particularly aortitis. Recent investigations support vascular magnetic resonance imaging (MRI) studies in this issue. We report our preliminary experience with this imaging technique in the study of the aorta and its proximal branches in patients with GCA and/or polymyalgia rheumatica (PMR). METHODS: Between 2000 and 2003, six patients with GCA and/or PMR seen in our department were diagnosed with aortitis using vascular MRI studies. In all cases, the study was performed according to a specifically designed protocol that included MRI and MR angiography (MRA). RESULTS: MRI was a hepful non-invasive method for diagnosis of aortitis in all cases, providing accurate information about its extent. In particular, MRI had a higher ability to detect earlier stages of vasculitis disclosing subclinical aortitis in five of the six patients. The main signs of early vascular inflammation observed were vessel wall thickness and oedema (six cases) and increased mural enhancement on postcontrast T1-weighted images (four cases). MRA disclosed lumen changes (stenosis) in two patients. On follow-up studies, whereas vascular stenosis and vessel wall thickness remained invariable, vascular wall oedema and contrast enhancement improved significantly when disease activity decreased. CONCLUSION: MRI may be a useful technique for diagnosing patients with occult major artery involvement in GCA, whether presenting with classic symptoms of temporal arteritis or PMR. Its utility for monitoring the course of the disease and response to treatment requires further confirmation.

[Prevalence of criteria indicating bone densitometry and risk factors for low bone mass and fracture in rheumatology outpatient units]. / Prevalencia de los criterios de indicación de densitometría ósea y de los factores de riesgo de baja masa ósea y fractura en unidades extrahospitalarias de reumatología.

Many organisms have proposed criteria to identify individuals with low bone mass or increased risk for osteoporotic fracture in order to provide them with the available diagnostic and therapeutic resources. Among these organisms are the WHO, the Catalan Agency for Health Technology Assessment (CAHTA) and the International Committee for Osteoporosis Clinical Guidelines (ICOCG). We designed a prospective multicenter study to determine the prevalence of indications for bone densitometry in rheumatology outpatient clinics by applying the criteria of these three organisms. Two hundred sixty-two women and 98 men aged 18 years or older who attended five rheumatology outpatient clinics were interviewed and their medical records were reviewed. The mean age was 58.3±13.4 years. Bone densitometry was indicated in 45% of the patients interviewed according to the CAHTA criteria, in 77% according to the WHO criteria and in 62% according to the ICOCG criteria (applicable only to women). The proportion of patients with indications for bone densitometry increased with age, and was higher in women. The concordance among criteria was low.
