Budesonide versus mesalamine for maintaining remission in patients refusing other immunomodulators for steroid-dependent Crohn's disease.

BACKGROUND & AIMS: To compare the efficacy of controlled-release budesonide capsules with that of mesalamine for maintaining remission and improving quality of life (QOL) in patients with steroid-dependent Crohn's disease. METHODS: Fifty-seven patients (25 men; mean age, 32 +/- 10.1 yr) with quiescent steroid-dependent Crohn's ileitis, ileocolitis, or colitis (Crohn's disease activity index <150) entered a prospective, investigator-blind trial. Patients were eligible for treatment with azathioprine but had not consented or had developed side effects. Patients were randomized to receive budesonide 6 mg/day (n = 29) or mesalamine 1 g 3 times/day (n = 28). Follow-up assessments were made every 2 months for up to 1 year or until relapse. At each visit, quality of life (QOL) was assessed using the Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS: There were no significant differences in baseline clinical characteristics between the study groups. The 1-year relapse rate was significantly lower in the budesonide group than in the mesalamine group (55% vs. 82%; 95% confidence interval, 12.4%-41%; P = 0.045). Patients assigned to budesonide also remained in remission longer (241 +/- 114 days vs. 147 +/- 117 days; 95% confidence interval, 32.7-155.3 days; P = 0.003). Compared with mesalamine, budesonide treatment also was associated with a better QOL throughout the study (mean total IBDQ scores 165 +/- 36 vs. 182 +/- 28, respectively; 95% confidence interval, -0.4 to 34.4, P = 0.0001). This advantage was confirmed in patients' self-assessed QOL scores. CONCLUSIONS: Over a 1-year period, controlled-release budesonide was significantly more effective than mesalamine for maintaining remission and improving the QOL of patients with steroid-dependent Crohn's disease.     

Effect of haemodialysis on serum levels of tumour markers in patients with end-stage renal failure

SUMMARY: We studied the effect of haemodialysis on the serum levels of tumour markers in 78 patients, 49 men and 29 women with a mean age of 61 ± 2 years, who had been undergoing haemodialysis for 39 ± 10 months. No patient had any clinical evidence of malignancy. Serum values of carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), squamous-cell-carcinoma-related antigen (SCC), neuron-specific enolase (NSE), tissue polypeptide antigen (TPA), CA 15-3, CA 19–9, and among males prostate-specific antigen (PSA) were determined before and after dialysis. Postdialysis values, after being corrected for haemoconcentration, were compared with predialysis values. A significant increase of 32% was observed in NSE levels ( P <0.001) and of 21% in CA 15-3 ( P <0.001) after haemodialysis. A lesser, but still statistically significant, increase (8-12%) was observed in SCC, AFP and CEA levels ( P <0.05), while the values of the remaining three markers remained unchanged. In conclusion, an increase in some tumour markers was found in our patients after dialysis, a finding which requires further investigation.     

Supernumerary marker chromosomes (SMCs) in Turner syndrome are mostly derived from the Y chromosome

DNA and FISH (fluorescence in situ hybridization) analysis were carried out in 12 patients with stigmata of Turner syndrome to determine whether the Supernumerary M arker C hromosome (SMC) found cytogenetically in each of these patients was derived from the Y chromosome. The presence of a Y chromosome in these patients may predispose them to develop gonadoblastoma. PCR-Southern blot analysis, followed by FISH, was used to detect the presence of Y chromosome material. The S ex determining R egion Y (SRY), T estis S pecific P rotein Y -encoded (TSPY) and Y -chromosome R NA R ecognition M otif (YRRM) genes, which map at Yp11.31, Yp11.1–11.2 and Yp11.2/Yq11.21–11.23, respectively, were selected as markers, because they span the whole Y chromosome, and more importantly, they are considered to be involved in the development of gonadoblastoma. It was shown that in 12 patients, all of whom had an SMC, the SMC of 11 was derived from the Y chromosome. Furthermore, the presence of the SRY, TSPY and YRRM gene sequences was determined and FISH analysis confirmed the Y origin of the SMCs. The methodology described in this report is a rapid, reliable and sensitive approach which may be easily applied to determine the Y origin of an SMC carried in Turner syndrome. The identification of an SMC is important for the clinical management and prognostic counseling of these patients with Turner syndrome.     

Detection of genetic alterations in primary bladder carcinoma with dual-color and multiplex fluorescence in situ hybridization

Cytogenetic studies of bladder cancer have shown several nonrandom aberrations. Numerical aberrations of both sex chromosomes were investigated in 32 primary bladder tumors with bicolor fluorescence in situ hybridization (FISH). Loss of chromosome Y and overrepresentation of chromosome X were observed in subgroups of male patients. Chromosome X was represented normally in female patients. Two of the above primary bladder tumors, a transitional cell carcinoma (TCC) and an adenocarcinoma, were further analyzed with both multiplex FISH (24-color M-FISH) and G-banding. Both cases exhibited 1) common breakpoints on 5q11 approximately q12 and 15q24; 2) involvement of the pericentromeric area of chromosome 13; 3) structural abnormalities of chromosomes 8 and 17, with loss of material on the short arm; 4) structural abnormalities involving chromosome 11; and 5) loss of chromosome Y. The TCC case also exhibited structural abnormalities of chromosome 9, resulting in loss of 9q. The combined G-banding and M-FISH findings could help reveal regions potentially involved in bladder tumorigenesis.     

Fast Eating Is Associated with Increased BMI among High-School Students

Fast self-reported eating rate (SRER) has been associated with increased adiposity in children and adults. No studies have been conducted among high-school students, and SRER has not been validated vs. objective eating rate (OBER) in such populations. The objectives were to investigate (among high-school student populations) the association between OBER and BMI z-scores (BMIz), the validity of SRER vs. OBER, and potential differences in BMIz between SRER categories. Three studies were conducted. Study 1 included 116 Swedish students (mean ± SD age: 16.5 ± 0.8, 59% females) who were eating school lunch. Food intake and meal duration were objectively recorded, and OBER was calculated. Additionally, students provided SRER. Study 2 included students (n = 50, mean ± SD age: 16.7 ± 0.6, 58% females) from Study 1 who ate another objectively recorded school lunch. Study 3 included 1832 high-school students (mean ± SD age: 15.8 ± 0.9, 51% females) from Sweden (n = 748) and Greece (n = 1084) who provided SRER. In Study 1, students with BMIz ≥ 0 had faster OBER vs. students with BMIz < 0 (mean difference: +7.7 g/min or +27%, p = 0.012), while students with fast SRER had higher OBER vs. students with slow SRER (mean difference: +13.7 g/min or +56%, p = 0.001). However, there was “minimal” agreement between SRER and OBER categories (κ = 0.31, p < 0.001). In Study 2, OBER during lunch 1 had a “large” correlation with OBER during lunch 2 (r = 0.75, p < 0.001). In Study 3, fast SRER students had higher BMIz vs. slow SRER students (mean difference: 0.37, p < 0.001). Similar observations were found among both Swedish and Greek students. For the first time in high-school students, we confirm the association between fast eating and increased adiposity. Our validation analysis suggests that SRER could be used as a proxy for OBER in studies with large sample sizes on a group level. With smaller samples, OBER should be used instead. To assess eating rate on an individual level, OBER can be used while SRER should be avoided.     

Diffuse splenic and visceral hemangiomas complicated by chronic consumption coagulopathy

Abstract The case of a 7-year-old girl with a 2 year history of easy bruising associated with thrombocytopenia is reported. On admission she presented with ecchymoses, abdominal distention and splenomegaly. Hemostasis investigation revealed a consumption coagulopathy. Several radiological studies failed to confirm the diagnosis of diffuse splenic and visceral hemangiomatosis, which was eventually estasblished by an explorative laparotomy. Platelet count and the other coagulation abnormalities progressively returned to normal after splenectomy, although the remaining hemangiomas were extensive.
