We aimed to clarify the relationship between plasma-free amino acid (PFAA) profiles and the Crohn’s disease (CD) activity index (CDAI) in patients with CD. Methods: We measured fasting PFAA concentrations in 29 patients with CD and their correlation with disease activity. Results: In all patients, significant correlations were noted between CDAI and concentrations of valine, methionine, leucine, histidine, tryptophan, alanine, tyrosine, total amino acids (TAAs), nonessential amino acids (NEAAs), essential amino acids (EAAs), and branched-chain amino acids (BCAAs). In patients with the ileo-colonic type of CD, significant correlations were noted between CDAI and valine, histidine, tryptophan, glutamine, TAA, NEAA, EAA, and BCAA. In ileal type, significant correlations were observed between CDAI and threonine, valine, histidine, serine, and glycine. In colonic type, significant correlations were noted between CDAI and valine, histidine, tryptophan, TAA, NEAA, EAA, and BCAA. Conclusions: In patients with CD, plasma amino acids appear to be associated with disease activity.

Abstract Introduction Assessment of disease activity in Crohn’s disease (CD) and ulcerative colitis (UC) is usually based on the physician’s evaluation of clinical symptoms, endoscopic findings, and biomarker analysis. The German Inflammatory Bowel Disease Activity Index for CD (GIBDICD) and UC (GIBDIUC) uses data from patient-reported questionnaires. It is unclear to what extent the GIBDI agrees with the physicians’ documented activity indices. Methods Data from 2 studies were reanalyzed. In both, gastroenterologists had documented disease activity in UC with the partial Mayo Score (pMS) and in CD with the Harvey Bradshaw Index (HBI). Patient-completed GIBDI questionnaires had also been assessed. The analysis sample consisted of 151 UC and 150 CD patients. Kappa coefficients were determined as agreement measurements. Results Rank correlations were 0.56 (pMS, GIBDIUC) and 0.57 (HBI, GIBDICD), with p < 0.001. The absolute agreement for 2 categories of disease activity (remission yes/no) was 74.2 % (UC) and 76.6 % (CD), and for 4 categories (none/mild/moderate/severe) 60.3 % (UC) and 61.9 % (CD). The kappa values ranged between 0.47 for UC (2 categories) and 0.58 for CD (4 categories). Discussion There is satisfactory agreement of GIBDI with the physician-documented disease activity indices. GIBDI can be used in health care research without access to assessments of medical practitioners. In clinical practice, the index offers a supplementary source of information.

1. Free amino acid concentrations in the plasma have been compared with those in liver and quadriceps muscle, in rats fed on diets containing 209 (control) and 31 (low-protein) g protein/kg. The effects of the low-protein diet on diurnal variations in these values were also measured.2. In the plasma, the total amino acid concentration was significantly lower in animals given the low-protein diet, at all times of day except 12.00 hours. In the liver, and to a lesser extent the muscle, total amino acid concentration was maintained.3. In the control animals, diurnal variation in the concentrations of both essential and non-essential amino acids was very similar in plasma, liver and muscle. In animals given the low-protein diet, although the same diurnal pattern was maintained for non-essential amino acids, that occurring among the essential amino acids had virtually disappeared.4. In plasma, the mean 24 h concentration of essential amino acids decreased from 24· mmol/l in control animals to only 1·29 mmol/l in the low-protein-fed animals. Concentrations in muscle and liver were reduced by a similar proportion (from 8·6 to 5·56 μmol/g and from 8·67 to 5·05 μmol/g respectively). Conversely the concentrations of non-essential amino acids in animals given the low-protein diet were increased in plasma (from 1·53 to 2·00 mmol/l), muscle (from 12·5 to 14·3 μmol/g), and liver (from 16·8 to 20·5 μmol/g), muscle showing the lowest increase.5. With the exceptions of lysine, threonine, cystine and tyrosine, the concentrations of all other essential amino acids were reduced more in liver than in muscle. The relationship between this and the failure to maintain plasma albumin concentrations is discussed.

RACIONAL - OBJETIVO: Avaliar a eficácia do infliximab no tratamento de pacientes com doença de Crohn ativa ou com fístulas. MÉTODOS: Quarenta e quatro portadores de doença de Crohn, refratários ao tratamento convencional, foram tratados com infliximab, na dose de 5 mg/kg, através de infusão endovenosa. RESULTADOS: Trinta deles (68,2%) obtiveram melhora dos sintomas, com regressão importante nos níveis de atividade da doença, medidos pelo CDAI (Crohn's Disease Activity Index). Oito (57,1%) de 14 portadores de fístulas também obtiveram bons resultados, com fechamento ou importante diminuição do fluxo destas. A tolerância à droga foi boa em todos os casos. CONCLUSÃO: O uso de infliximab nestes casos parece ser boa opção terapêutica, com baixos índices de efeitos colaterais.
