However, patients with chronic kidney disease (CKD) on hemodialysis (HD) have lower aminotransferase serum levels than those with preserved renal function, which might adversely affect the assessment of liver injury among these patients <a class="elsevierStyleCrossRefs" href="#bib4">4,5</a>.</p><p id="para20" class="elsevierStylePara elsevierViewall">Some factors are implicated in the reduction of AST and ALT serum levels among patients with CKD on HD such as lower pyridoxine serum levels, higher homocysteine levels and hemodilution due to fluid retention <a class="elsevierStyleCrossRefs" href="#bib6">6-8</a>. In patients on HD infected with the hepatitis B (HBV) or hepatitis C viruses (HCV), other factors also contribute to the decrease in aminotransferases, such as the lower viremia caused by the dialysis procedure through the sequestration of the virus by the dialyzer; the higher production of hepatocyte growth factor (HGF), which is induced via dialysis and accelerates liver regeneration; and the increased endogenous α-interferon serum levels and lymphocyte activation that fight the viral agent together <a class="elsevierStyleCrossRefs" href="#bib9">9-11</a>.</p><p id="para30" class="elsevierStylePara elsevierViewall">However, most studies evaluating serum aminotransferase levels have involved patients with CKD on HD, and only one article has described a reduction in serum aminotransferase levels among patients with predialysis CKD <a class="elsevierStyleCrossRef" href="#bib12">12</a>.

This study is the first to find a direct correlation between a reduction in GFR and a decrease in aminotransferases.</p><p id="para210" class="elsevierStylePara elsevierViewall">In fact, we observed that AST and ALT serum levels tended to be higher during the initial stages (2 and 3) of CKD compared with the later stages (4 and 5). The possible increases in the number of patients within each CKD stage might reveal a more gradual and significant decrease in serum aminotransferases levels; this finding is in line with the reduction in the GFR. Importantly, the sample size must be regarded as one of the limitations of this study.</p><p id="para220" class="elsevierStylePara elsevierViewall">Some hypotheses have been offered to explain the reduction of serum aminotransferase levels among patients with CKD on HD: a deficiency of pyridoxine, hemodilution and hyperhomocysteinemia <a class="elsevierStyleCrossRefs" href="#bib6">6-8</a>. In fact, Ono et al. reported that patients with CKD on HD with pyridoxine deficiencies have lower serum aminotransferase levels than those without vitamin deficiencies <a class="elsevierStyleCrossRef" href="#bib7">7</a>. Lopes et al. observed hemodilution and found that weight loss during HD was associated with a rise in ALT serum levels (r=0.3, <span class="elsevierStyleItalic">p</span><0.001) <a class="elsevierStyleCrossRef" href="#bib6">6</a>. Huang et al. evaluated the serum homocysteine levels of 145 patients undergoing HD and found that they were negatively related to AST (r=0.4, <span class="elsevierStyleItalic">p</span><0.001). Thus, AST serum levels might reflect the high metabolic activity of homocysteine and influence its serum levels <a class="elsevierStyleCrossRef" href="#bib8">8</a>. Importantly, these hypotheses concern patients with CKD under HD; however, they cannot be rejected with regard to patients during predialysis. Therefore, another limitation of this study is that it did not measure homocysteine or pyridoxine.</p><p id="para230" class="elsevierStylePara elsevierViewall">Interestingly, this study found that almost all of the patients had aminotransferase levels below the ULN, even when they were using several potentially hepatotoxic drugs (4 per patient on average) such as statins, which were used by approximately 60% of the patients <a class="elsevierStyleCrossRef" href="#bib18">18</a>. Moreover, a considerable number of patients had diabetes mellitus, which might lead to liver inflammation (steatohepatitis) and a consequent rise in liver enzymes <a class="elsevierStyleCrossRef" href="#bib19">19</a>.</p><p id="para240" class="elsevierStylePara elsevierViewall">Another interesting finding of this study concerns the significant reduction in BMI based on CKD progression. This behavior is explained not only by the fact that patient weight is included in the calculation of the GFR but also given the malnutrition associated with CKD <a class="elsevierStyleCrossRefs" href="#bib13">13,20,21</a>. In fact, the progressive decrease of BMI might reduce dyslipidemia or glucose levels, thereby promoting a regression of underlying fatty liver disease that contributes to decreased aminotransferase levels <a class="elsevierStyleCrossRef" href="#bib22">22</a>. To reduce this possible confound, the association between GFR and aminotransferases was adjusted for BMI; however, it remained significant. Moreover, malnutrition might reduce the stocks of B-complex vitamins, especially pyridoxine, which act as a co-factor in the synthesis of aminotransferases by reducing their production <a class="elsevierStyleCrossRef" href="#bib23">23</a>.</p><p id="para250" class="elsevierStylePara elsevierViewall">Male patients presented lower GFRs than their female counterparts. This finding might be related to the CKD progression rate, which occurs more rapidly in males, thereby increasing the chances that these patients are at more advanced stages of the disease <a class="elsevierStyleCrossRef" href="#bib24">24</a>.</p><p id="para260" class="elsevierStylePara elsevierViewall">This preliminary study revealed that the decrease in AST and ALT serum levels among patients with CKD occurs before the start of dialysis, and these enzymes are independently decreasing factors associated with HD. Future studies, should collect larger samples of patients with CKD to evaluate the evidence of aminotransferase reduction in these patients, such as pyridoxine and homocysteine serum levels.</p><p id="para270" class="elsevierStylePara elsevierViewall">In conclusion, the AST and ALT serum levels of patients with pre-dialysis CKD tended to decrease in proportion to their CKD progression, and these levels were negatively correlated with their creatinine serum levels and directly correlated with the GFR.</p></span><span id="cesec50" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle100">AUTHOR CONTRIBUTIONS</span><p id="para280" class="elsevierStylePara elsevierViewall">Lopes EP was responsible for the conception and design of this paper as well as the data analysis and interpretation.
