RESUMO

INTRODUCTION: Patients with haemophilia may have lower levels of bone mineral density (BMD) compared with the general population. Moreover, haemophilic patients have increased risk factors for low bone mineral density (LBMD) such as arthropathy and resulting immobility, increasing their risk for osteoporosis and fractures. AIM: To assess the prevalence of LBMD and associated risk factors among a group of Colombian haemophilic patients. METHODS: In this case-control study, 90 patients with haemophilia A and B, over the age of five, were recruited. Controls were healthy participants matched by age, gender, body mass index (BMI), socioeconomic status, and race. All participants underwent dual energy X-ray absorptiometry (DXA) and the Global Physical Activity Questionnaire. Blood tests were collected to evaluate LBMD determinants in cases. RESULTS: BMD was lower in cases than in the control group. BMD of femoral necks was 0.907 g/cm2 in cases vs. 1.020 g/cm2 in controls (P = .019), and BMD of hips 0.930 g/cm2 in cases vs. 1030 g/cm2 in controls (P = .019). The greater the severity of haemophilia, the lower BMD in spine, femoral neck, and hips. Elevated C-protein levels were found in 44.1% of patients with LBMD and 14.8% with normal BMD (P = .003). The study found an adjusted prevalence ratio of 2.11, indicating that haemophilic patients are two times more likely to have LBMD (CI95% = 1.43-3.11 P < .001). CONCLUSION: Results from the present study showed that haemophilia was associated with a higher frequency of LBMD. Severity of haemophilia, haemophilic arthropathy, and elevated C-reactive protein levels was directly associated with LBMD.

RESUMO

BACKGROUND: Myocardial involvement occurs in about 20% of patients with mixed connective tissue disease. The purpose of this study was to determine the prevalence of conduction disturbances, their association with other manifestations of the disease. OBJECTIVE: Determine the prevalence of cardiac conduction disturbances in patients with mixed connective tissue disease attended in an institute in Mexico City and their relation with other manifestations of the disease. METHODS: One hundred thirteen patients admitted to the Institute with a diagnosis of mixed connective tissue disease were divided into those with conduction disturbances (n = 23) and those without (n = 90). Over a mean follow-up of 10.2 +/- 7.8 years, clinical course, treatment, duration of the disease, types of conduction disturbances and systemic alterations were examined. RESULTS: There was an overwhelming predominance of women in both groups. Conduction disturbances occurred in about 20% of the patients with mixed connective tissue disease and that was not possible to find significant differences in the outcome of them. As could be expected a significant difference between the two groups was QRS axis, related to anterior hemiblock, the most common conduction alteration observed. During the follow-up one patient death in-group A, but none in group B. CONCLUSION: Conduction disturbances were present in 20%; in agree with other authors in the literature. However, did not participate in the outcome of the disease.
