Background
Micronutrient deficiencies have been discussed in the literature regarding post-transplant recipients. A proposed theory is that immunosuppressive medications or altered immune system cause pyridoxine deficiency post-transplant. The purpose of this study is to identify solid organ transplant recipients with pyridoxine deficiency to assess the clinical significance, improve the patients overall long-term outcomes, and improve standard of care
Methods
This is a retrospective study with data collected from 48 solid organ transplant recipients, who were admitted to UAMC who had a pyridoxine level checked post transplantation and nutritional evaluation.
Results
48 recipients were identified to have pyridoxine level checked after transplant and have a formal dietary consultation. Of the 48 patients, 30 (63%) of the study cohort were diagnosed with pyridoxine deficiency. General characteristics of the cohort: mean age of 46 (SD +/-16) years, male 63%, white race 50%, kidney recipients 33%, heart 31%, kidney with other organ 21%, liver 11%, lung and pancreas 2% each. Mean time interval between transplant and level checked was 910 days (SD +/-456). Mean weight at the time of consultation was 80 kg (SD+/-20.7). Groups with normal and low pyridoxine were compared for all study variables as described above. All liver (5/5), lung (1/1) and pancreas (1/1) transplant recipients were found to be deficient. 9/10 (90%) kidney with other organ, 8/16 (50%) kidney alone, and 6/15 (40%) of heart recipients were deficient in pyridoxine (p=0.03). More subjects in the deficient group were on fluconazole (90% vs. 67%: p=.05) , received induction with thymoglobulin (77% vs. 24%: p=.028), received thymoglobulin for rejection (56% vs. 0%: p=.006), were malnourished (54% vs.17%: p=0.06), and were normal weight (12/15) or underweight (3/3). Mean length of stay in hospital at the time of transplantation was longer in deficient group (25 vs. 12 days, p=.09). Neurological comorbidities were not different between the two groups.
Conclusions
Pyridoxine deficiency seems to be relatively common post-transplant, especially those who are malnourished, underweight or normal weight, and who received thymoglobulin induction. Prospective studies are needed to confirm and evaluate the significance of deficiency.
