Abstract

Item does not contain fulltext, BACKGROUND: The 24- and 48-hour tetrahydrobiopterin (BH4) loading test (BLT) performed at a minimum baseline phenylalanine concentration of 400 mumol/l is commonly used to test phenylketonuria patients for BH4 responsiveness. This study aimed to analyze differences between the 24- and 48-hour BLT and the necessity of the 400 mumol/l minimum baseline phenylalanine concentration. METHODS: Data on 186 phenylketonuria patients were collected. Patients were supplemented with phenylalanine if phenylalanine was <400 mumol/l. BH4 20mg/kg was administered at T = 0 and T = 24. Blood samples were taken at T=0, 8, 16, 24 and 48 h. Responsiveness was defined as >/= 30% reduction in phenylalanine concentration at >/= 1 time point. RESULTS: Eighty-six (46.2%) patients were responsive. Among responders 84% showed a >/= 30% response at T = 48. Fifty-three percent had their maximal decrease at T = 48. Fourteen patients had >/= 30% phenylalanine decrease not before T = 48. A >/= 30% decrease was also seen in patients with phenylalanine concentrations <400 mumol/l. CONCLUSION: In the 48-hour BLT, T = 48 seems more informative than T = 24. Sampling at T = 32, and T = 40 may have additional value. BH4 responsiveness can also be predicted with baseline blood phenylalanine <400 mumol/l, when the BLT is positive. Therefore, if these results are confirmed by data on long-term BH4 responsiveness, we advise to first perform a BLT without phenylalanine loading and re-test at higher phenylalanine concentrations when no response is seen. Most likely, the 48-hour BLT is a good indicator for BH4 responsiveness, but comparison with long term responsiveness is necessary.

16. Total energy expenditure in human immunodeficiency virus-infected men and healthy controls.

Abstract

Department of Internal Medicine, Academic Medical Center, Amsterdam University, Meibergdreef, The Netherlands. Total daily energy expenditure (TEE) has been reported to be slightly decreased in weight-stable acquired immune deficiency syndrome (AIDS) patients. This conclusion is based on a comparison of TEE measurements to the data reported by others. We measured TEE in nine weight-stable human immunodeficiency virus (HIV)-infected homosexual men (Centers for Disease Control [CDC]-II to -IV) without active opportunistic disease and nine age-, sex-, and height-matched healthy controls using the doubly labeled water technique for 2 weeks, and resting energy expenditure (REE) using the ventilated-hood technique. TEE in HIV-Infected patients was not significantly different from that in healthy controls (221 +/- 12.5 and 210 +/- 9 kJ.kg lean body mass [LBM]-1.d-1, respectively, NS). REE was approximately 10% higher in HIV patients than in healthy controls (134 +/- 4 and 125 +/- 4 kJ.kg LBM-1.d-1, respectively, P = .02). The energy spent in relation to physical activity was not different between HIV-Infected patients and the controls (66 +/- 10 and 64 +/- 5 kJ.kg LBM-1.d-1, respectively, NS). In conclusion, REE is increased by about 10% in weight-stable HIV-infected men without active opportunistic disease. TEE and the energy spent during physical activity are not different in this group of patients versus healthy controls. This is in contrast to the previously reported decrease of TEE in weight-losing AIDS patients. Therefore, the energy requirements of stable HIV-infected patients are not decreased compared with those of healthy subjects.
