Changes in the nutritional state and immune-serological parameters of esophagectomized patients fed jejunaly with glutamine-poor and glutamine-rich nutriments.

BACKGROUNDS/AIMS: In our former study we investigated the effect of glutamine-rich (I) and glutamine-poor (II) jejunal diet in operated patients with acute pancreatitis. In the glutamine-rich diet group clinical benefit and fast recovery of IgG, IgM, serum proteins, retinol-binding protein, albumin could be measured. In the present study the effects of the two types of jejunal diets I and II have been compared on the basis of changes in some immune parameters of 36 patients treated with subtotal esophagectomy for malignancy. METHODOLOGY: In randomized controlled trial data of two groups, I. patients with glutamine-rich Stresson Multi Fibre diet (23 patients) and II. patients with Nutrison Multi Fibre glutamine-poor diet (13 patients) were analyzed. Levels of serum proteins were measured by laser nephelometry, CD markers of lymphocytes by flow cytometry, phagocyte activity by chemiluminescence. RESULTS: Level of proteins decreased on the 2nd postoperative day in both groups, then gradually increased postoperatively. In increase of level of serum protein, retinol-binding protein, prealbumin there was no difference between the two groups. CONCLUSIONS: In patients treated with subtotal esophagectomy, the glutamine-rich enteric diet did not result in faster recovery in levels of prealbumin, retinol-binding protein, immunoglobulins and in outcome of patients than the glutamine-poor nutriment.

Five-year follow-up of 665 Hungarian patients with undifferentiated connective tissue disease (UCTD).

OBJECTIVE: To determine the clinical symptoms and the panel of autoantibodies of patients with early undifferentiated connective tissue disease (UCTD) followed for at least 1 year. METHODS: 716 UCTD patients with manifestations suggestive but not diagnostic of specific connective tissue disease (CTD) were recruited and followed up between 1994-1999. The patients with early UCTD were subdivided into those with isolated Raynaud's phenomenon (RP) (50 patients), unexplained polyarthritis (31 patients) and "true" UCTD (665 patients). UCTD was diagnosed on the basis of clinical manifestations suggestive of a connective tissue disease and the presence of at least one non-organ specific autoantibody. The patients' sera were tested for anti-nuclear (ANA), as well as for nine different specific autoantibodies (anti-dsDNA, -Sm, -RNP, -SSA, -SSB, -Scl-70, -centromere, -Jo1 and -PM-Scl). RESULTS: The most common clinical manifestations of UCTD included RP, arthritis/arthralgias, pleuritis/pericarditis, sicca symptoms, cutaneous involvement (photosensitivity, rash), central nervous symptoms, peripheral neuropathy, fever, vasculitis, less pulmonary involvement and myositis. 230 of the 665 true UCTD patients (34.5%) developed a defined CTD (28 systemic lupus erythematosus [SLE], 26 mixed connective tissue disease [MCTD], 19 progressive systemic sclerosis [PSS], 45 Sjögren's syndrome, 3 polymyositis/dermatomyositis [PM/DM], 87 rheumatoid arthritis [RA], and 22 systemic vasculitis. 435 of 665 patients (65.4%) remained in the UCTD state, and 82 of 665 patients (12.3%) achieved complete remission with symptoms not reappearing within the 5-year period. The highest probability of evolution to a defined CTD was during the first 2 years after onset: of 230 UCTD patients 183 (79.5%) developed major organ symptoms and signs. In particular skin and cardiac complications seemed to spread during the follow-up period in those patients who progressed to SLE. The condition of 18/50 patients with isolated RP evolved to UCTD and 3 of 31 patients with unexplained polyarthritis progressed to definite CTD (2 patients RA and one MCTD). CONCLUSION: In our study most of the UCTD patients did not develop a definite CTD, but during the follow-up period we found new clinical and serological manifestations. One-third of the UCTD patients showed progress into different types of specific CTD.

Anti-endothelial cell antibodies in mixed connective tissue disease: frequency and association with clinical symptoms.

OBJECTIVE: Anti-endothelial cell antibodies (AECA) have been described in a number of systemic autoimmune-inflammatory diseases. However, little is known about the relationship of AECA with mixed connective tissue disease (MCTD). METHODS: Using an ELISA, the presence of AECA was evaluated in the sera of 33 patients with MCTD and of 30 healthy subjects as controls. Serum levels of AECA were correlated with clinical activity, as well as the existence of various organ manifestations. RESULTS: Significantly increased AECA production was observed in MCTD patients (OD = 0.337+/-0.193) compared to controls (OD = 0.136+/-0.065). In addition, patients with active MCTD exerted significantly elevated serum AECA levels (OD = 0.487+/-0.090) than did patients with inactive MCTD (OD = 0.135+/-0.040) or controls. MCTD patients with pulmonary hypertension had a tendency of increased serum AECA levels (OD = 0.452+/-0.080) compared to patients without this manifestation (OD = 0.307+/-0.039). Sera of MCTD patients with AECA concentrations higher or lower than the mean serum AECA level in controls+2SD (OD = 0.266) were considered as AECAhigh (n = 19/33) and AECAlow (n = 14/33), respectively. Interestingly, all patients with active disease had AECAhigh, while all inactive MCTD patients had AECAlow sera. IgG purified from ten MCTD sera (OD = 0.415+/-0.290) showed a tendency to up-regulate E-selectin expression on cultured human umbilical vein endothelial cells (HUVEC) compared to IgG from control sera. In addition, AECAhigh MCTD sera exerted significantly increased stimulatory effect on endothelial E-selectin expression (OD = 0.651+/-0.190) compared to AECAlow (OD = 0.178+/-0.110) or control sera (OD = 0. 131+/-0.080). CONCLUSION: AECA may activate endothelial cells by the up-regulation of E-selectin expression and thus may be implicated in the pathogenesis of MCTD. Furthermore, serum AECA may be a useful marker of endothelial activation and clinical activity in this disease.

Monocyte functions in patients with mixed connective tissue disease.

The authors investigated the number and functions of peripheral blood monocytes in patients with mixed connective tissue disease. Moderate monocytopenia was detected in the active stage of the disease. There was a close correlation between the sensitized sheep red blood cell binding capacity of monocytes and the elevated levels of circulating immune complexes. The yeast phagocytosis of monocytes and the chemotactic activity were normal in patients with mixed connective tissue disease. C3b receptor mediated phagocytosis of monocytes decreased in the active and inactive stages of the disease. This study suggests that the decreased function of C3b receptors of monocytes is related to the pathogenesis of this disease.

Polymorphonuclear functions in patients with mixed connective tissue disease.

Polymorphonuclear leukocytes (PMNs) from 29 patients with mixed connective tissue disease (MCTD) were studied "in vitro" for their phagocytic and chemotactic function as well as for granulocyte alkaline phosphatase (GAP) activity. Fc-receptor expression detected by EA-rosette formation was comparable to the control. Yeast-phagocytosis, C3b-receptor mediated phagocytosis and chemotaxis of PMNs, however, significantly decreased in MCTD. At the same time, photometric measure of alkaline phosphatase activity indicated a nearly two fold increase in PMNs from patients with MCTD. Although no correlation was found between PMN functions and the activity of the disease, PMN disorders may play a role in pathogenesis of these connective tissue disorders.
