High levels of platelet-to-lymphocyte ratio may predict reduced risk of end stage of renal disease in Chinese patients with MPO-ANCA associated vasculitis / 中南大学学报(医学版)

OBJECTIVES@#Platelet-to-lymphocyte ratio (PLR) has recently been investigated as a new inflammatory marker in many inflammatory diseases, including systemic lupus erythematosus and immunoglobulin A vasculitis. However, there were very few reports regarding the clinical role of PLR in patients with anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis. This study was thus undertaken to investigate the relationship between inflammatory response and disease activity in Chinese patients with myeloperoxidase-anti-neutrophil cytoplasmic antibody (MPO-ANCA) associated vasculitis. Furthermore, we evaluated whether PLR predicts the progression of end stage of renal disease (ESRD) and all-cause mortality.@*METHODS@#The clinical, laboratory and pathological data, and the outcomes of MPO-ANCA associated vasculitis patients were collected. The Spearman correlation coefficient was computed to examine the association between 2 continuous variables. Cox regression analysis was used to estimate the association between PLR and ESRD or all-cause mortality.@*RESULTS@#A total of 190 consecutive patients with MPO-ANCA associated vasculitis were included in this study. Baseline PLR was positively correlated with CRP (r=0.333, P<0.001) and ESR (r=0.218, P=0.003). PLR had no obvious correlation with Birmingham Vasculitis Activity Score (BVAS). Patients having PLR≥330 exhibited better cumulative renal survival rates than those having PLR<330 (P=0.017). However, there was no significant difference in the cumulative patient survival rates between patients with PLR≥330 and those with PLR<330 at diagnosis (P>0.05). In multivariate analysis, PLR is associated with the decreased risk of ESRD (P=0.038, HR=0.518, 95% CI 0.278 to 0.963). We did not find an association between PLR with all-cause mortality using multivariate analysis (HR=1.081, 95% CI 0.591 to 1.976, P=0.801).@*CONCLUSIONS@#PLR is positively correlated with CRP and ESR. Furthermore, PLR may independently predict the risk of ESRD.

Transtornos depressivos em crianças com leucemia linfoide aguda e com insuficiência renal crônica terminal: estudo de série de casos / Depressive disease in children with acute lymphocytic leukemia and end stage of renal disease/case series study

OBJETIVO: Investigar a presença de transtornos depressivos em crianças portadoras de leucemia linfoide aguda (LLA) e insuficiência renal crônica terminal (IRCT) atendidas no IMIP. MÉTODO: Estudo descritivo do tipo série de casos, composto por 52 crianças entre 8 e 15 anos portadoras de LLA e de IRCT. RESULTADOS: Três (5,8 por cento) casos preenchiam os critérios para episódio depressivo maior (EDM), sendo dois portadores de IRCT e um portador de LLA. Oito (15,4 por cento) preenchiam os critérios para transtorno distímico (TD), todos eles portadores de IRCT. A associação entre faixa etária e EDM não foi significativa (p=0,327). Entretanto, a faixa etária foi significante em relação ao TD (p=0,014), todos os seus portadores tinham entre 12 e 15 anos de idade. A associação entre os transtornos depressivos e o tempo de evolução da doença de base não foi significante. Contudo, observou-se uma tendência a quanto maior o tempo de evolução da doença de base, maior a associação com o TD. CONCLUSÃO: A frequência de EDM ficou dentro da faixa encontrada na literatura para escolares saudáveis, entretanto, a de TD foi mais alta. Não foram encontradas diferenças significantes entre as faixas etárias no diagnóstico de EDM. Porém, corroborando a literatura, a faixa etária maior prevaleceu em relação ao TD.

OBJECTIVE: To Investigate the presence of depressive disease in children with acute lymphocytic leukemia (ALL) and end stage of renal disease (ESRD). METHOD: A case series study including 52 children suffering of ALL or ESRD aged 8 to 15 years. RESULTS: Three patients (5.8 percent) had major depressive episode (MDE), two of them with ESRD and one with ALL. Eight patients (15.4 percent) had dysthymic disorder (DD), all of them had ESRD. The association between age and MDE was not meaningful. On other hand, the association between age and DD was significant, and all of the patients aged between 12 and 15 years. The association between depressive diseases and evolution time of base disease was not significant. However, it was observed that the bigger the time of base disease evolution, the bigger the association with DD. CONCLUSION: The frequency of MED was not different from the literature, but the frequency of DD was higher. In opposition to what was expected, there wasn't difference between the ages in MED. However, in agreement with the literature, it prevailed the highest ages in DD.
