CLINICAL TRIAL
JOURNAL ARTICLE
Effect of L-carnitine and conjugated linoleic acid supplements on haemoglobin levels and haptoglobin genotype in chronic kidney disease.
OBJECTIVE: To investigate the efficacy of L-carnitine (LC) and conjugated linoleic acid (CLA) supplements on haemoglobin levels and inflammatory markers in chronic kidney disease (CKD) patients with different haptoglobin (HP) genotypes.
METHODS: This clinical trial study was conducted at Imam Khomeini Hospital, Ardabil, and Labbafinejad Hospital, Tehran, Iran, from March 2014 to March 2015, and comprised male patients with CKD and anaemia. Anthropometric factors were recorded and demographic data was collected using general questionnaires. LC (1 g/day) and CLA (2.4 g/day) supplements were given to the patients for a month. Blood samples were taken to measure haematological and inflammatory markers at the beginning and end of the study. Haptoglobin genotypes were determined using polymerase chain reaction (PCR). SPSS 21 was used for data analysis.
RESULTS: Among the 40 patients in the study, HP2-2 genotype was the most prevalent genotype (62.5%). The level of haemoglobin was significantly increased in the patients at the end of the study (p< 0.05). No significant changes were found in the weight, body mass index and serum levels of Interleukin-6, high-sensitivity C-reactive protein, ferritin, total iron-binding capacity and iron (p>0.05 each).
CONCLUSIONS: Regular diet supplementation with LC plus CLA can improve haemoglobin levels in CKD patients with anaemia.
