Coorte Sarar: atividade de doença, capacidade funcional e dano radiológico em pacientes com artrite reumatoide submetidos à artroplastia total de quadril e joelho / Sarar cohort: disease activity, functional capacity, and radiological damage in rheumatoid arthritis patients undergoing total hip and knee arthroplasty

RESUMO

RESUMOObjetivos:A coorte Sarar é composta por pacientes portadores de artrite reumatoide (AR) e artrite idiopática juvenil (AIJ) submetidos a artroplastias de quadril e joelho no hospital Sarah-Brasília. O objetivo deste estudo foi avaliar fatores clínicos e laboratoriais associados à atividade de doença, capacidade funcional e dano radiológico em pacientes com AR, participantes dessa coorte.Métodos:Estudo transversal, com coleta de dados em revisão de prontuário.Resultados:Foram incluídos 32 pacientes, com tempo médio de início da doença de 240 meses. Dezenove pacientes foram submetidos a ATJ e 17, a ATQ. Foi encontrada correlação positiva entre dose máxima de metotrexato (MTX) durante a evolução e Clinical Disease Activity Index (CDAI) (R = -0,46, p = 0,011) e negativa com Simplified Erosion and Narrowing Score (SENS) (R = -0,58, p = 0,004). Valores de SENS foram maiores nos pacientes com fator reumatoide (FR) (p = 0,005) e anticorpo antipeptídeo cíclico citrulinado 3 (anti-CCP3) positivo (p = 0,044), nos com maiores títulos de FR (p = 0,037) e anti-CCP3 (p = 0,025) e menores nos pacientes com história familiar de AR (p = 0,009). Valores de HAQ foram maiores em pacientes mais idosos (p = 0,031). Na regressão linear múltipla, somente “dose máxima de MTX” e “história familiar” permaneceram com associação significativa com SENS (r2= 0,73, p < 0,001 para ambas as variáveis). No modelo que avaliou CDAI, apenas “dose máxima de MTX” permaneceu com associação significativa (r2 = 0,35, p = 0,016).Conclusão:Na coorte Sarar, fatores clínicos e laboratoriais estiveram relacionados à atividade de doença, capacidade funcional e dano radiológico, semelhantemente a estudos que avaliaram pacientes com menor tempo de doença.

ABSTRACT

ABSTRACTObjectives:The Sarar cohort consists of patients with rheumatoid arthritis and juvenile idiopathic arthritis who underwent hip or knee arthroplasties at hospital SARAH-Brasília. The objective of this study was to evaluate clinical and laboratory factors associated with disease activity, functional capacity and radiological damage in rheumatoid arthritis patients, participants in this cohort.Methods:Cross-secal study, with data collection achieved from medical records review.Results:Thirty-two patients were included, with a mean time of disease onset of 240 months. Nineteen patients underwent total knee and 17 total hip arthroplasty. There was a positive correlation between maximum dose of methotrexate and Clinical Disease Activity Index (R = −0.46, p = 0.011), and a negative one with Simplified Erosion and Narrowing Score (R = −0.58, p= 0.004). Simplified Erosion and Narrowing Score values were higher in patients with rheumatoid factor (p = 0.005) and anti-cyclic citrullinated peptide antibody 3 positivity (p = 0.044), in those with higher rheumatoid factor (p = 0.037) and anti-cyclic citrullinated peptide antibody 3 (p = 0.025) titers, and lower in patients with family history of rheumatoid factor (p = 0.009). Health Assessment Questionnaire values were higher in older patients (p = 0.031). In multiple linear regression, only “maximum dose of methotrexate” and “family history” remained with significant association with Simplified Erosion and Narrowing Score (r2 = 0.73, p < 0.001 for both variables). In the model evaluating “Clinical Disease Activity Index” only “maximum dose of methotrexate” remained significantly associated (r2 = 0.35, p = 0.016).Conclusion:In the Sarar cohort, clinical and laboratory factors were related to disease activity, functional capacity and radiological damage, similar to studies evaluating patients with lower disease duration.
