Abstract Background: Sickle cell disease (SCD) is an autosomal recessive genetic disease in which a mutation occurs in the β-globin chain gene, resulting in abnormal hemoglobin levels. In an environment with reduced oxygen concentration, red blood cells change their conformation, resulting in chronic hemolysis and consequent anemia and vaso-occlusive crises with injuries to several organs, with a significant impairment of the osteoarticular system. This study aimed to verify the chronic osteoarticular alterations and their association with clinical and laboratory characteristics of patients with SCD with a more severe phenotype (SS and Sβ0), on a steady-state fasis. Methods: Fifty-five patients were referred to a medical consultation with a specialized assessment of the locomotor system, followed by laboratory tests and radiographic examinations. Results: In total, 74.5% patients had hemoglobinopathy SS; 67.3% were female; and 78.2% were non-whites. The mean patient age was 30.5 years. Most patients (61.8%) reported up to three crises per year, with a predominance of high-intensity pain (65.5%). Radiographic alterations were present in 80% patients. A total of 140 lesions were identified, most which were located in the spine, femur, and shoulders. Most lesions were osteonecrosis and osteoarthritis and were statistically associated with the non-use of hydroxyurea. Conclusions: There was a high prevalence of chronic osteoarticular alterations, which was statistically associated only with the non-regular use of hydroxyurea.

Resumo Apresentamos o caso de uma paciente portadora de insuficiência cardíaca com prótese valvar aórtica biológica e alterações vasculares compatíveis com arterite de Takayasu (AT) que chegou ao serviço em uso de corticoides e em profilaxia para febre reumática (FR). Não foi possível afastar a associação entre ambas as enfermidades.

Abstract In this article, we present the case of a patient with heart failure with biological aortic valve prosthesis and multiple vascular changes consistent with Takayasu arteritis (TA) who was seen in our department receiving corticosteroids and secondary prevention of rheumatic fever (RF); it was not possible to exclude the association between both diseases.
