    Abstract Introdução: Síndromes mielodisplásicas (SMD) são um grupo heterogêneo de distúrbios hematopoiéticos clonais que têm maior chance de progressão para Leucemia Mielóide Aguda (LMA). O Transplante Alogênico de Células Tronco Hematopoiéticas (TCTH) representa o tratamento curativo mais efetivo para SMD até o momento. Objetivos: descrever o perfil dos pacientes com SMD, que realizaram TCTH alogênico, no Hospital Universitário Walter Cantídio (HUWC) em Fortaleza, Ceará. Metodologia: estudo retrospectivo observacional e descritivo com onze pacientes com SMD de novo que realizaram TCTH alogênico no período de fevereiro de 2015 a junho de 2018. Resultados: total de onze pacientes, idade ao diagnóstico de dezenove a sessenta e seis anos (média 46 anos). Três pacientes deleção do 5q (duas com alterações adicionais), quatro hipocelulares, um com displasia de múltiplas linhagens (p53 positivo na imunohistoquímica), duas com excesso de blastos tipo 2, uma com sideroblastos em anel (baixo risco). Dez doadores aparentados com fonte das células de sangue periférico e um não aparentado com fonte de medula óssea. Óbitos: uma paciente com excesso de blastos e um paciente com displasia multilinhagem. Conclusão: é possível identificar pacientes com SMD de baixo risco que tenham indicação de TCTH alogênico. Anormalidades citogenéticas adicionais à deleção 5q não tiveram impacto negativo. Também reforçamos a importância prognóstica do p53.

    Abstract Objective: This study aims to evaluate the markers of tubular phosphate handling in adults with sickle cell anemia (SCA) and the influence of hydroxyurea (HU), the degree of anemia and Hb F concentration on these markers.
    Methods: Eighty-eight steady state SCA patients in outpatient follow-up in Fortaleza, Ceara, Brazil and 31 healthy individuals were included in this study. Vitamin D (25OHD) was measured by enzyme-bound fluorescence assay, intact parathyroid hormone (iPTH) by electrochemiluminescence, and serum and urinary phosphate and creatinine by colorimetric methods. Details of Hb F and HU use were obtained from clinical records. Tubular reabsorption of phosphate (TRP) and maximum tubular reabsorption of phosphate (MTRP) were calculated. SCA patients were stratified according to the use of HU, degree of anemia and percentage of Hb F. The significance level was set for p-values <0.05.
    Results: Compared to controls the 25OHD level (25 ± 11 vs. 30 ± 9 pg/mL) was lower in SCA, while serum phosphate and MTRP were higher (3.86 ± 0.94 vs. 3.46 ± 0.72 and 3.6 ± 1.21 vs. 3.21 ± 0.53, respectively). There was no significant difference in iPTH, TRP and phosphaturia. Serum phosphate showed correlation with TRP (r = 0.32; p-value = 0.008) and MTRP (r = 0.9; p-value <0.001) in SCA. Patients taking HU, especially those with Hb F >10 % presented reduced serum phosphate levels, and TRP and MTRP rates. Those with mild anemia presented reduced serum phosphate levels and MTRP rates.
    Conclusion: Serum phosphate levels and renal phosphate reabsorption rate were increased in SCA. HU use, high Hb F concentration and total Hb were associated with better control of tubular phosphate handling markers.

    Abstract Clinical Background: Renal involvement in sickle cell disease (SCD), called sickle cell nephropathy (SCN), includes several renal manifestations, such as renal acidification defect, distal nephron dysfunction, renal papillary necrosis, and proteinuria related to glomerular injury, leading to end-stage renal disease. Epidemiology: Many patients with SCD have a defect in urinary concentration, a problem caused by the destruction of the renal medulla that initiates in childhood. The presence of proteinuria in SCD is age-related and starts as microalbuminuria in adolescence and progresses to macroalbuminuria. Proteinuria is responsible for the progression to chronic kidney disease in some patients with SCD with glomerular filtration rate (GFR) decreased due to interactions between various processes involving the vascular, glomerular, tubular, and interstitial compartments of the kidney. Challenges: Renal complications are hardly identifiable in the early stages, as serum creatinine increases only in the final stages of SCN. Subnormal GFR and elevated serum creatinine levels develop only when there is significant proteinuria. Prevention and Treatment: The identification of biomarkers of early, non-invasive kidney injury, and their inclusion in clinical practice will contribute to the identification of the mechanisms involved in the development of renal syndromes, facilitating the development of more effective strategies in the prevention and treatment of SCD.
