ABSTRACT
ABSTRACT

Objective:

To investigate the efficacy and safety of febuxostat on renal function in CKD stage 3 diabetic nephropathy patients.

Methods:

Patients in our hospital with chronic kidney disease (CKD) stage 3 diabetic nephropathy (DN) complicated by high serum uric acid (360 µmol/L) were recruited. Patients were then divided into treatment group and control group according to the random number table method. All the patients received low purine diet, renin-angiotensin-aldosterone system (RAAS) inhibitors, and adequate routine hypoglycemic treatment. Febuxostat was employed only in the treatment group. The levels of blood uric acid (sUA), serum creatinine (Scr), cystatin C (cys-c), eGFR, 24-hour urine protein quantification, albuminuria, and creatinine ratio (ACR) were evaluated in all patients before and after treatment at 4, 8, 12, and 24 week.

Results:

No difference was found before treatment between the two groups. After treatment at 4, 8, 12, and 24 week, the levels of sUA, SCr, cys-c, and eGFR between the two groups were significant different (P<0.05). There was no difference in 24-hour urine protein quantification, albuminuria, and creatinine ratio between two groups before treatment, and significant differences were observed after treatment. Fifty percent of patients from the treatment group achieved the treatment goal with 20 mg febuxostat at 4 weeks. Tubular markers were also decreased with the treatment.

Conclusions:

Febuxostat can reduce uric acid and improve renal function effectively in patients with CKD stage 3 diabetic nephropathy, while being well tolerated. However, the conclusion is still uncertain due to the short term of the study.
RESUMO
RESUMO

Objetivo:

Investigar a eficácia e segurança do febuxostat na função renal em pacientes com DRC estágio 3, com nefropatia diabética.

Métodos:

Foram recrutados pacientes em nosso hospital com nefropatia diabética (DN) estágio 3 de doença renal crônica (DRC) complicada por ácido úrico sérico alto (360 µmol/L). Os pacientes foram então divididos em grupo de tratamento e grupo controle, de acordo com o método da tabela de números aleatórios. Todos os pacientes receberam dieta pobre em purinas, inibidores do sistema renina-angiotensina-aldosterona (RAAS) e tratamento hipoglicêmico de rotina. O Febuxostat foi empregado apenas no grupo de tratamento. Os níveis de ácido úrico no sangue (AIU), creatinina sérica (Scr), cistatina C (cys-c), TFGe, quantificação de proteínas na urina em 24 horas, razão albumina e creatinina (ACR) foram avaliados em todos os pacientes antes e após o tratamento às 4, 8, 12 e 24 semanas.

Resultados:

Nenhuma diferença foi encontrada antes do tratamento entre os dois grupos. Após o tratamento nas 4, 8, 12 e 24 semanas, os níveis de sUA, SCr, cys-c e TFGe entre os dois grupos foram significativamente diferentes (P <0,05). Não houve diferença na quantificação de proteínas na urina em 24 horas, albuminúria e razão de creatinina entre dois grupos antes do tratamento, e diferenças significativas foram observadas após o tratamento. Cinquenta por cento dos pacientes do grupo de tratamento atingiram a meta de tratamento com 20 mg de febuxostat em 4 semanas. Marcadores tubulares também foram reduzidos com o tratamento.

Conclusões:

O Febuxostat pode reduzir o ácido úrico e melhorar a função renal efetivamente em pacientes com nefropatia diabética estágio com DRC no estágio 3, sendo bem tolerado. No entanto, a conclusão ainda é incerta devido ao curto prazo do estudo.
