Risk of osteoporotic fracture in women using the FRAX tool with and without bone mineral density score in patients followed at a tertiary outpatient clinic ‒ An observational study

OBJECTIVES

Fragility fractures increase morbidity and mortality. Adding assessment of clinical risk factors independently or as a previous step to Bone Densitometry (BD) should provide better accuracy in fracture risk prediction. FRAX tool might be used to stratify patients in order to rationalize the need for BD and risk classification. The primary objective of this study is to describe and perform comparisons between the estimated risk of fractures in 10 years using the FRAX calculator based on clinical factors with and without BD results for women aged 40 or more with clinical diseases monitored in tertiary care service in internal medicine.

METHODS

Cross-sectional. Women over 40 years with BD in the previous year. After medical chart review, identification of risk factors and risk estimations using FRAX-BRAZIL with (FRAX BDI) and without (FRAX BDNI) the inclusion of T-score.

RESULTS

239 women. Age 65 ± 10.35 years. BMI 29.68 ± 6.27kg/m².

RISK FACTORS

32(13.4%) previous fractures; 23 (9.6%) current smoking; 78 (32.6%) corticosteroids use; 44 (18.4%) rheumatoid arthritis; 38 (15.9%) secondary causes; FRAX scores were higher when BD was not included. Spearman correlation coefficients between FRAX BDNI and FRAX BDI for major fractures r = 0.793 (95% CI 0.7388‒0.836). For hip fractures r = 0.6922 (95% CI 0.6174‒0.75446) CONCLUSION: Using FRAX to estimate 10-year fracture risk without BD data might be a reliable tool for screening, even for patients with a high prevalence of risk factors, improving accessibility and equity in health systems. The present study's data suggest an overestimation of fracture risk with FRAX BDNI, suggesting that it is safe to be widely used as a screening tool.

External validity of type 2 diabetes clinical trials on cardiovascular outcomes for a multimorbid population

AIM

To investigate the external validity of recent antihyperglycaemic trials evaluating cardiovascular outcomes in a multimorbid population.

MATERIALS AND METHODS

Selection criteria of 15 randomized controlled trials from the 2020 American Diabetes Association Standard of Care statement were applied in a stepwise manner to tertiary care patients with type 2 diabetes. Primary outcomes were the number of patients eligible per individual trial and for the aggregate of trials. Secondary outcomes included patient predictors of trial eligibility.

RESULTS

Of 1059 patients, the mean (SD) age was 66 (10.74) years, the median (IQR) Charlson index was 2 (2, 3) and 458 (43%) had documented cardiovascular disease. The median (IQR) number of patients included in individual trials was 263 (174.25-308.75) and 795 (75.1%) of them were eligible for at least one trial. Among those 264 ineligible, 127 (48.1%) had an HbA1c level of 7% or less and no cardiovascular disease; 53.5% and 34.4% of the patients were eligible for two and three different classes of drugs, respectively. The strongest predictor of trial eligibility was cardiovascular disease (risk ratio 2.17, 95% CI 2.01-2.35).

CONCLUSIONS

A considerable proportion of multimorbid patients would be eligible for recent antihyperglycaemic trials. This positive finding can be attributed to development guidance in diabetes trials and the different approach we took, in which we evaluated inclusion by trials as an aggregate.

Electrocardiographic changes in dermatomyositis and polymyositis

INTRODUCTION

Cardiac involvement is frequent in inflammatory myopathies. Electrocardiogram (ECG) may show evidence of this involvement and its changes should be well-known and described.

OBJECTIVES

Due to the lack of studies in the literature, we conducted an analysis of the ECG findings in patients with dermatomyositis (DM) and polymyositis (PM), comparing them with a control group.

METHODS

This cross-sectional study compared the ECG of 86 individuals with no rheumatic disorders (controls) with 112 patients (78 DM and 34 PM), during 2010-2013. The ECG findings between DM and PM were also compared.

RESULTS

Demographic characteristics, comorbidities and ECG abnormalities were similar between controls and patients (p>0.05), except for a higher frequency of left ventricular hypertrophy (LVH) in patients (10.7% vs. 1.2%, p=0.008). Demographic characteristics, comorbidities, clinical and laboratory manifestations, were also similar between the groups PM and DM, except for the presence of cutaneous lesions only in DM. One-third of the patients had ECG abnormalities, which were more prevalent in PM than DM (50% vs. 24.4%, p=0.008). LVH, left atrial enlargement, rhythm and conduction abnormalities were more frequent in PM than DM (p<0.05 for all), especially the left anterior fascicular block.

CONCLUSIONS

We showed distinct ECG changes between DM and PM and a higher frequency of LVH in patients compared to controls. Investigation of cardiac involvement should be considered even in asymptomatic patients, especially PM. Further studies are necessary in order to determine the correlation of ECG findings with other complementary tests, clinical manifestations, disease activity and progression to other cardiac diseases.

Cutaneous mucinosis in mixed connective tissue disease

Cutaneous mucinosis is a group of conditions involving an accumulation of mucin or glycosaminoglycan in the skin and its annexes. It is described in some connective tissue diseases but never in association with mixed connective tissue disease. This report concerns two cases of cutaneous mucinosis in patients with mixed connective tissue disease in remission; one patient presented the papular form, and the other reticular erythematous mucinosis. These are the first cases of mucinosis described in mixed connective tissue disease. Both cases had skin lesions with no other clinical or laboratorial manifestations, with clinical response to azathioprine in one, and to an association of chloroquine and prednisone in the other.

Current and relevant concepts in psoriatic arthritis

Psoriatic arthritis (PsA) is a systemic, polymorphic joint disease with variable presentation and clinical course. The outcome depends on the association with severe comorbidities such as diabetes, hypertension and dyslipidemia. Early diagnosis requires a high degree of clinical suspicion, especially when skin manifestations are subtle and poorly defined. Progressive erosive disease can occur in up to half of patients, associated with anatomical and functional changes in about 20%. Thus, the prognosis of PsA remains unclear, especially if diagnosis and treatment are delayed. Based on extensive literature review (PubMed and Lilacs) and experience of our services, new concepts of immunogenetics, pathophysiology, and clinical and therapeutic aspects are discussed. Factors that reduce the quality of life and life expectancy of patients, as well as new guidelines for treatment, will be emphasized. Control of inflammation, especially in enthesitis and axial forms of PsA, was made possible due to the introduction of anti-TNF biologics. Finally, the role of GRAPPA (Group for Research and Assessment of Psoriasis and Psoriatic Arthritis) should be emphasized, since it promotes meetings and joint studies between rheumatologists and dermatologists to provide scientific evidence for the sweeping changes in clinical management and treatment of patients with PsA.
