Methods: Among patients undergoing PLV, 120 had paired pre- and postoperative (<1 week) Doppler echocardiograms. Effects of preoperative MR were studied by comparing 45 patients with no preoperative MR (MR,) and 75 patients with significant MR (MR+; MR = 1.51 when MR is enumerated as none = 0, mild = 1, moderate = 2). Results: MR, patients as compared with the MR+ group were older (53.8 vs. 49.2 years, P = 0.047), had less frequent dilated cardiomyopathy (33.3% vs 49.3%,P <0.01), similar ventricular dimension (72.3 mm vs 73.0 mm), septal thickness (9.5 mm vs 9.6 mm), posterior wall, fractional shortening (15.9% vs 16.8%) and ventricular mass (330 g vs 345 g), resulting in comparably reduced functional capacity (NYHA 3.40 vs 3.67). Although the MR, group required significantly less frequent mitral procedure (64.4% vs 84.0%, P < 0.01) and shorter cardiac arrest time, they had similar postoperative MR (0.22 vs 0.39), highly significant parallel reduction in ventricular dimension (P < 0.001 in either group), and improved %FS (P <0.001 in either group), resulting in similar hospital survival (87.1% vs 86.4%) and 90-day survival (71.1% vs 78.7%) with significantly comparable improvement in functional class (P = 0.011 in both groups). Histological severity of interstitial fibrosis (P = 0.80), weight (P = 0.93), and thickness (P = 0.76) of excised myocardium was comparable between the two groups. Conclusion: Patients with no preoperative MR were found to benefit from PLV as did patients with significant MR. Beneficial effects of PLV appeared to derive mainly from volume reduction rather than abolished MR in this study.(J CARD SURG 2003;18 (Suppl 2):S95-S100) [source]

Symptoms and quality of life in obese children and adolescents with non-alcoholic fatty liver disease

Aliment Pharmacol Ther,31, 396,406 Summary Background, Data on the quality of life (QOL) of children with non-alcoholic fatty liver disease (NAFLD) are needed to estimate the true burden of illness in children with NAFLD. Aim, To characterize QOL and symptoms of children with NAFLD and to compare QOL in children with NAFLD with that in a sample of healthy children. Methods, Quality of life and symptoms were assessed in children with biopsy-proven NAFLD enrolled in the NASH Clinical Research Network. PedsQL scores were compared with scores from healthy children. For children with NAFLD, between-group comparisons were made to test associations of demography, histological severity, symptoms and QOL. Results, A total of 239 children (mean age 12.6 years) were studied. Children with NAFLD had worse total (72.8 vs. 83.8, P < 0.01), physical (77.2 vs. 87.5, P < 0.01) and psychosocial health (70.4 vs. 81.9, P < 0.01) scores compared with healthy children. QOL scores did not significantly differ by histological severity of NAFLD. Fatigue, trouble sleeping and sadness accounted for almost half of the variance in QOL scores. Impaired QOL was present in 39% of children with NAFLD. Conclusions, Children with NAFLD have a decrement in QOL. Symptoms were a major determinant of this impairment. Interventions are needed to restore and optimize QOL in children with NAFLD. [source]


Metabolic and histological features of non-alcoholic fatty liver disease patients with different serum alanine aminotransferase levels

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 4 2009
V. W.-S.
Summary Background, Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in affluent countries. Serum alanine aminotransferase (ALT) level is commonly performed to monitor NAFLD patients, but its clinical relevance is unclear. Aim, To evaluate the metabolic and histological features of NAFLD patients with different ALT levels. Methods, A total of 173 consecutive patients with biopsy-proven NAFLD were studied. Patients with persistently normal ALT and those with abnormal ALT were compared. Results, Patients with persistently normal ALT had lower steatosis grade than patients with abnormal ALT, but they had similar degree of lobular inflammation, ballooning and fibrosis. Among 19 patients with ALT below 0.5 times the upper limit of normal (ULN) at the time of liver biopsies, 8 (42%) and 3 (16%) had steatohepatitis and significant fibrosis respectively. The within-patient coefficient of variance was similarly high in patients with simple steatosis and steatohepatitis (33.5). Age and glucose, but not ALT, were independent factors associated with significant fibrosis. Discussion, Metabolic factors, but not ALT, are associated with histological severity. Patients with ALT < 0.5 × ULN may still have non-alcoholic steatohepatitis (NASH) and significant fibrosis. Evaluation of NAFLD patients should be based on metabolic risk factors, but not ALT level.

DOES MATRIX METALLOPROTEINASE ACTIVITY PREDICT SEVERITY OF ACUTE PANCREATITIS?

ANZ JOURNAL OF SURGERY, Issue 9 2006
Murat Aynaci
Background: Matrix metalloproteinases (MMP) modulate end-organ complications of acute pancreatitis, but the correlation between increased MMP production and histological severity of disease remains unclear. We examined the role of MMP and pancreas histology on experimental acute pancreatitis. Methods: Forty male Wistar albino rats were subjected to cerulein-induced pancreatitis (8, 16, 24 and 32 h groups) or sham treatment. The animals were killed at different time points and pancreatic tissues were harvested to assess MMP (1, 2 and 9) activity and inflammatory changes. Results: Compared with other groups, 8 h group had decreased tissue MMP-1 concentrations. MMP-9 concentrations were lower in 24-h and 32-h groups, as were histological severity scores. MMP-2 activity did not differ among groups. Pancreatitis was prominent in 8-h, 16-h and 24-h groups by means of histology. Conclusion: Induction of pancreatitis by cerulein altered pancreatic MMP levels in the early phase of inflammation. Inhibition of MMP-2 and MMP-9 paralleled histological scores. Therefore, MMP may have a predictive value to assess histological severity. [source]


Henoch-Schönlein purpura nephritis in children: risk factors, prevention and treatment

ACTA PAEDIATRICA, Issue 12 2009

Abstract Aim:, To identify risk factors for a child with Henoch-Schönlein purpura (HSP) either to develop nephritis (HSPN) or to contract progressive course and to obtain the currently available evidence on the efficacy of treatment options in both preventing and treating the established renal disease. Method:, Review of the literature published over the last two decades. Results:, Persistent or recurrent purpura, severe abdominal symptoms and an older age proved as the most significant risk factors for later HSPN. The risks of long-term renal impairment are the highest in children having at presentation nephritic/nephrotic syndrome and/or more than 50% of glomeruli occupied by large crescents or sclerosing lesions. Randomized controlled trials (RCT) do not support short course prednisone at presentation of HSP in preventing persistent renal disease. Many uncontrolled studies using various treatment regimens have reported outcomes considered better than expected. However, the data from RCTs are sparse and no treatment options for the established renal disease can be currently recommended based on RCTs. Conclusion:, Severity and/or duration of extrarenal HSP symptoms and an older age are the most significant risk factors for developing HSPN, whereas clinical and histological severity at HSPN onset are in general predictive of a long-term renal impairment. The existing evidence does not support of short course prednisone in preventing persistent renal disease. A well-designed RCTs are needed in children with moderately severe or rapidly progressive (crescentic) HSPN. [source]
