Association of angiotensin converting enzyme (ACE) gene polymorphism with hypertension in a Bangladeshi population.

The association of angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism with hypertension has not been confirmed. Inconsistencies may be due to the differences of background population characteristics. Till date, there has been no report in Bangladeshi population. This study was to examine the association of ACE (I/D) polymorphism with hypertension. Fifty-one primary hypertensives and fifty-two normotensives were recruited from a hospital in Dhaka city. Height, weight and blood pressure were measured. ACE (I/D) genotypes was established using polymerase chain reaction protocol. The genotype and allele frequencies did not differ significantly (P > 0.05) between the groups. In logistic regression analysis, adjusted for age, sex and body mass index, the genotypes were not associated with hypertension (DD vs II: Adds ratio = 2.6, P = 0.34; ID vs II: 0.4, 0.23; ID + DD vs II: 0.8, 0.69). In this hospital-based sample of Bangladeshi people, significant association of ACE I/D genotype with hypertension was not observed.

Clinico-pathological predictive factors of response to interferon therapy in chronic hepatitis C.

We performed a clinico-pathological study to determine which pre-treatment factors could predict the response to interferon (IFN) therapy in 55 Japanese patients with chronic hepatitis C. Responses to the IFN therapy were evaluated as sustained response, relapse and non-response by the presence or absence of serum hepatitis C virus (HCV) RNA during the course of treatment and at least 6-months post-treatment. The numbers of sustained response, relapse and non-response were 16 (29.0%), 25 (45.5%) and 14 (25.5%), respectively. Eight out of 16 sustained response cases (50%) showed HCV genotype III. Eight among 10 patients with HCV genotype III (80%) were sustained responders. HCV genotypes were found to be correlated with the response to the IFN therapy (p < 0.0001). None of the histological features, the types of the IFN therapy and other clinical factors showed significant differences. These findings suggest that outcome of the IFN therapy in chronic hepatitis C can be predicted by a virological factor, and that HCV genotype III is a useful predictor of a favorable outcome.
