Background: There is no study evaluating the use of glycated albumin (GA) for the detection of post-transplantation diabetes mellitus (PTDM) in kidney transplant recipients. We evaluated the overall accuracy of GA at four months after kidney transplantation.

Methods: Diagnostic test accuracy study including 134 kidney transplant recipients without pre-existing diabetes.

Background: Glycated hemoglobin (HbA1c) is an alternative test used for the diagnosis and monitoring of diabetes in kidney transplant recipients. Immunosuppressive drugs are the most important risk factors related with changes in the glucose metabolism after transplant. It is still unknown if they impact on the variability of HbA1c.

Aims/hypothesis: Disparities in HbA1c levels have been observed among ethnic groups. Most studies were performed in patients with diabetes mellitus (DM), which may interfere with results due to the high variability of glucose levels. We conducted a systematic review and meta-analysis to investigate the effect of ethnicity on HbA1c levels in individuals without DM.

Background: Early detection of post-transplantation diabetes mellitus (PTDM) allows prompt clinical and pharmacological interventions, reducing the chance of adverse outcomes. We conducted a systematic review and meta-analysis to determine the overall diagnostic accuracy of glycated hemoglobin (HbA1c) for the diagnosis of renal PTDM.

Methods: We searched MEDLINE, Embase and SCOPUS up to June 2016.

We conducted a literature review about renal posttransplantation diabetes mellitus (PTDM), a glucose metabolism alteration with high incidence. Immunosuppressive therapy, by different diabetogenic mechanisms, is the major risk factor for PTDM. Although corticosteroids and calcineurin inhibitors are the drugs most related to PTDM, the mechanisms of other drugs have been also investigated.

Objectives: Studies suggest that iron deficiency anaemia (IDA) is associated with higher HbA1c levels. We conducted a control–case study to investigate the effect of IDA on HbA1c levels, measured by two commonly used methods, in non-diabetic individuals.

Design And Methods: A total of 122 patients were included, 61 patients with IDA and 61 patients without anaemia.

We carried out a systematic review and meta-analyses of studies that evaluated the possible effects of anemia, variant hemoglobin, and uremia on A1C levels in individuals without diabetes (DM). Medline and Embase were searched for studies that measured A1C values in groups with and without iron deficiency anemia (IDA) and/or iron deficiency (ID), variant hemoglobin and/or uremia by standardized methods. The difference between A1C levels in the groups with and without interferences was obtained by using random-effects meta-analysis and the effect size was presented as absolute difference of means (95% CI).

Background: The role of glycated hemoglobin (A1C) in the screening and diagnosis of posttransplantation diabetes mellitus (PTDM) is still not entirely understood. We evaluated the use of A1C test in renal transplant recipients at four months after transplantation.

Methods: A total of 122 out of 274 patients without previous diabetes that underwent kidney transplantation were enrolled.

Synopsis of recent research by authors named "Ana Laura Pimentel"

  • - Ana Laura Pimentel's research primarily focuses on the diagnostic accuracy and implications of glycated albumin (GA) and glycated hemoglobin (HbA1c) in the context of post-transplantation diabetes mellitus (PTDM) among kidney transplant recipients, emphasizing the significance of early detection for better clinical management.
  • - Her systematic reviews and meta-analyses reveal ethnic disparities affecting HbA1c levels in non-diabetic individuals, alongside the influence of immunosuppressive therapy and iron deficiency anemia on glucose metabolism post-transplantation.
  • - Pimentel's studies underscore the complexity of evaluating diabetes markers in post-transplant patients, highlighting the challenges posed by factors such as anemia and medication effects on glycemic control.
