ABSTRACT
Background: The study was conducted to evaluate and compare the protective effects of spironolactone (alone) and its effects along with ACE inhibitor (ramipril) on diabetics (30-70year) in relation to proteinuria and state of diabetic nephropathy.Methods: A comparative, prospective, non-randomized, non-blinded experimental study was conducted on 56 patients (30-70year) of diagnosed type 2 diabetes mellitus showing proteinuria. Total duration of study was about one year from October 2017 to October 2018. Patients were divided in two groups, group A (n=28, spironolactone 25mg and ramipril 5mg) and group B (n=27, spironolactone 25mg). Subjects were followed over 12weeks and baseline and 12-week urine ACR being compared.Results: Both the group after receiving respective drug were followed for 3month duration and response were assessed by measuring urine ACR value at end of 3months. Mean values of baseline and follow up urine ACR for group A and group B were 471.5±465.62, 244.66±237.54 and 474.88±438.94, 268.42±268.16 respectively, P value found to be >0.05 at 95%C.I. It was observed that percentage reduction of urine ACR were 48% and 43.47% in group A and group B respectively.Conclusions: In the study, it was concluded that spironolactone had significant effect over proteinuria reduction over follow up period in patient with diabetic nephropathy though there was no additional statistically significant advantage of addition of spironolactone and ACE inhibitor over proteinuria reduction. Significant reduction of proteinuria occurred in both group A and group B over 12weeks follow up period, 48 % reduction in group A and 43.47% in group B. This difference proved statistically not significant after applying independent t-test.
ABSTRACT
PURPOSE: Human angiotensin converting enzyme (ACE) gene shows an insertion/deletion polymorphism in 16 intron, and three genotypes are determined by whether a 287 bp fragment of the DNA is present or not; II, ID and DD genotype. DD genotype has been suggested as a risk factor of chronic nephrotic disease such as IgA nephropathy and diabetic nephropathy, various cardiovascular diseases and several other diseases. ACE activity increases in acute hepatitis, chronic persistent hepatitis, chronic active hepatitis and cirrhosis. On the other hand, patients with fatty livers have normal ACE activity. This study was designed to find out the relation between polymorphsims of the ACE genes and neonatal hyperbilirubinemia in Koreans. METHODS: The genomic DNA was isolated from 110 full-term Korean neonates who had hyperbilirubinemia with no obvious causes (serum bilirubin?12 mg/dL) and 164 neonates of a control population (serum bilirubin?12 mg/dL). We performed polymerase chain reaction (PCR) to see the allele of the ACE gene. Electrophoresis was done in the PCR products in 1.5 percent agarose gel, and then DNA patterns were directly visualized under ethidium bromide staining. RESULTS: ACE genotypes in the hyperbilirubinemia group are as follows; 26.36 percent for II, 53.64 percent for ID, 20.00 percent for DD, 0.532 for I allele and 0.468 for D allele. These distributions were not significantly different from those in the control group; 24.39 percent for II, 51.83 percent for DI, 23.78 percent for DD, 0.503 for I allele and 0.497 for D allele. CONCLUSION: In this study, ACE gene polymorphism was detected in the neonatal hyperbilirubinemia and control group. The most frequent genotype was ID. Our results indicate that the ACE gene polymorphism is not associated with the prevalence of neonatal hyperbilirubinemia in Koreans.
