  • Neutrophile to lymphocyte and platelet to lymphocyte ratios predict clinical response to bDMARD in naïve spondylarthritis patients
    Publication . Martins, F. Rajão; Bernardes, M.; Sequeira, G.; Costa, L.; Carvalho, P. David
    Objective: We aim to study association between neutrophile to lymphocyte (NLR) and platelet to lymphocyte (PLR) ratios and disease activity, and their value to predict bDMARD response. Methods: A set of spondylarthritis (SpA) patients under bDMARD registered in the Reuma.pt registry was studied. Sociodemographic, clinical and laboratorial variables were assessed on bDMARD initiation, 6, 12, 18 and 24 months (M) thereafter. Univariable and multivariable generalized estimation equations models assessed associations with disease activity. The NLR and PLR predictive value was assessed using univariable and multivariable logistic regression models. Results: A total of 170 patients were included. Most were male (54.7%), with a predominantly axial phenotype (84.7%). Significant associations were observed between NLR [B=1.55, 95% confidence interval (CI) = (1.38; 1.74)] and PLR [(B=1.16, 95% CI = (1.09; 1.24)] with ASDAS-CRP (p < 0.001). Both baseline ratios predicted ∆ ASDAS-CRP ≥ 1.1 at 6 months [OR = 2.20, 95% CI = (1.21, 4.00) for NLR; OR = 1.02, 95% CI = (1.01, 1.04) for PLR, p < 0.01)]. PLR was a significant predictor of ∆ ASDAS-CRP ≥ 1.1 in all timepoints [OR (12 M) = 1.02, 95% CI = (1.00, 1.03), p < 0.05; OR (18M) = 1.02, 95% CI = (1.01, 1.03), p < 0.001; OR (24M) = 1.01, 95% CI = (1.01, 1.02), p < 0.01]. Conclusion: NLR and PLR were associated with disease activity during the follow up of these patients. They seem to be significant predictors of therapeutic response to bDMARD in naïve SpA patients.

  • Polyarthritis due to metastatic calcinosis in a patient with new WT1 gene mutation resolution after renal transplantation
    Publication . Martins, F. Rajão; Gonçalves, Francisco; Guedes, A.; Sequeira, G.; Ribeiro, C.
    Metastatic calcinosis is an uncommon condition characterized by diffuse soft tissue calcification, which may occur with advanced chronic kidney disease (CKD), typically in those undergoing kidney replacement therapy (1, 2). Deposits usually appear around large joints such as the elbow, hip, and shoulder. Periarticular deposits may lead to arthralgia, reduced joint mobility, and neurovascular symptoms. Sustained elevation of serum phosphate levels is the main contributor in CKD patients.
