RESUMEN
AIM: To determine EBNA-1 expression in the tissue of patients with diffuse large B-cell lymphoma and its relationship to bcl-2 expression. METHODS: Paraffin-embedded tissue from 24 cases of diffuse large B-cell lymphoma were stained immunohisto chemically with monoclonal antibody anti-EBNA-1 and anti-bcl-2 using Streptavidin Biotin Complex method. The bcl-2 expression was measured as negative (no staining), positive 1 (weak staining), and positive 2 (moderate to strong staining). The relationship between the immunohisto chemistry results was examined. RESULTS: From the 24 samples, 12 (50%) were EBNA-1 positive and 14 (58.3%) showed expression of bcl-2. Eleven of the 14 samples (90%) showed expression of bcl-2 were EBNA-1 positive, while only 3 of these samples (10%) were EBNA-1 negative. The relationship between bcl-2 expression and EBNA-1 was statistically significant (Chi square-uncorrected 11.2571, p= 0.0036). CONCLUSION: Our results showed that 50% of diffuse large B-cell lymphoma were EBNA-1 positive. Furthermore, EBNA-1 seemed to be correlated with bcl-2 expression.

AIM: To assess the prevalence of macroalbuminuria and microalbuminuria in hypertensive patients with type 2 diabetes in 10 Asian countries. METHODS: This cross-sectional clinic-based epidemiological study is a subanalysis of data collected from patients attending three medical centres in Indonesia from May 2002 to October 2002. A total of 207 patients were enrolled, of which 177 patients constituted the per protocol population (patients with bacteriuria and haematuria were excluded). RESULTS: Overall, the prevalence of diabetic kidney disease was high, with macroalbuminuria comprising 44.7% (41.2-48.1;95% confidence interval) and microalbuminuria comprising 33.0% (29.7-36.3; 95% confidence interval). While the majority (91.53%) of patients were receiving treatment for hypertension, only 6.21% of the patients had systolic/diastolic blood pressures below the 130/85 mmHg target. CONCLUSION: The prevalence of microalbuminuria and macroalbuminuria was high in hypertensive patients with type 2 diabetes in Indonesia, which is indicative of an impending pandemic of diabetic cardiovascular and renal diseases in the region.
