Objective:
To explore the effects of medium and long-chain triglyceride on the immune function of burn patients during early postburn stage and its possible mechanism.
Methods:
Thirty burn patients with TBSA exceeding 30% were enrolled in this study and were randomly divided into two groups (n = 15 in each group). The patients in F group were supplemented orally with enteral nutrient Fresubin 750MCT containing medium (MCT) and long-chain triglyceride (LCT), and those in N group with Nutrition containing only LCT. All the patients were treated with nutritional support beginning from 24 PBH, continued for 10 days. The changes in plasma levels of IL-2, IL-4, PGE(2) and T lymphocyte transformation rate (LTR) in peripheral blood of patients in the two groups were determined on 1, 4, 7 and 10 postburn days (PBDs).
Results:
The plasma IL-2 level in all time points exhibited no difference in all patients (P > 0.05). The plasma level of PGE(2) on PBD 4 in F group was obviously lower than that in N group (P < 0.01). The plasma level of IL-4 on PBDs 4, 7 and 10 in F group were evidently higher than that in N group (P < 0.01). The T LTR in peripheral blood on PBDs 4 and 7 in F group was much higher than that in N group (P < 0.05 - 0.01).
Conclusion:
Enteral nutrient containing MCT/LCT seemed to be superior to that containing only LCT in the improvement of postburn immune function in burn patients.

The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
