Nephroprotective Effect

Introduction: Renal damage is a common clinical manifestation in diabetic patients. Therefore, nephroprotective effect is a desirable property for an antidiabetic agent. Natural compounds belonging to Terminalia phillyreifolia (TP) owing to their potent antioxidant and anti-inflammatory activity may prove to be such agents. Objectives: The objectives of the present study were to evaluate methanolic extract of TP bark for its antihyperglycemic, antioxidant and nephroprotective effect in streptozotocin (STZ) induced diabetes mellitus and nephropathy in rats. Materials and Methods: Diabetic male Wistar rats were divided into five groups; namely, normal control, disease control, standard (NPH insulin, subcutaneously), BE100 (bark extract 100 mg/kg, p.o.) and BE300 (bark extract 300 mg/kg, orally). Treatment was continued for 8 weeks. Plasma glucose levels, oxidative stress parameters, serum creatinine levels, blood urea nitrogen (BUN) levels, per day urine output, urinary protein excretion (UPE) and kidney hypertrophy index were determined at appropriate time points. Results: Untreated animals developed severe hyperglycemia and major disturbance in renal function. Rats in standard and BE treated groups had significantly lower plasma glucose levels and oxidative stress markers as compared to disease control animals. BE rats also exhibited nearly normal urine volumes indicating better glomerular filtration rate. They had lower urinary protein, serum creatinine, BUN levels and lower renal hypertrophy index as compared to untreated animals. Conclusion: TP Bark extract corrected the hyperglycaemia and exerted protective effect against diabetes induced renal damage in rats, which may be partly due to its anti-oxidant effect. Therefore, TP extract can be further evaluated as potential antidiabetic therapy

Nephroprotective Effect

Objectives: Nephrotoxicity is a renal-specific situation in which the excretion of toxic metabolites is reduced due to toxic agents and drugs. Gentamicin is an antibiotic belongs to aminoglycoside group which may induce nephrotoxicity due to induction of oxidative stress. Curcumin is a component of traditional medicine with significant nephroprotective effect. Therefore, the objective of the present study was to evaluate the nephroprotective effect of curcumin on gentamicin-induced nephrotoxicity. Methods: A total of 30 male Sprague-Dawley rats were used which divided into Group 1 (n=10): Rats treated with distilled water 5 ml/kg plus normal saline 5 ml/kg for 12 days, Group 2 (n=10): Rats treated with distilled water 5 ml/kg plus gentamicin 100 mg/kg for 12 days, and Group 3 (n=10): Rats treated with curcumin 100 mg/kg plus gentamicin 100 mg/kg for 12 days. Blood urea, serum creatinine, malondialdehyde (MDA), kidney injury molecule (KIM-1), and cystatin-C were measured in both control and experimental groups. Results: Rats treated with gentamicin showed nephrotoxicity as evident by significant elevation in blood urea, serum creatinine, KIM-1, MDA, and cystatin-C sera levels. Curcumin leads to significant reduction of blood urea and serum creatinine compared to gentamicin group, p<0.05. Curcumin also reduced MDA, KIM-1, and cystatin-C sera levels significantly compared to gentamicin group, p<0.01. Conclusion: Curcumin produced significant nephroprotective effect on gentamicin-induced nephrotoxicity through modulation of oxidative stress and inflammatory biomarkers.

This work presents the characterization of a self-powered glucose biosensor using individual sequential assays of human plasma glucose obtained from diabetic patients. The self-powered glucose biosensor is exploited to optimize the assay parameters for sensing plasma glucose levels. In particular, the biofuel cell component of the system at pH 7.4, 37 °C generates a power density directly proportional to plasma glucose and exhibited a maximum power density of 0.462 mW·cm−2 at a cell voltage of 0.213 V in 5 mM plasma glucose. Plasma glucose is further sensed by monitoring the charge/discharge frequency (Hz) of the integrated capacitor functioning as the transducer. With this method, the plasma glucose is quantitatively detected in 100 microliters of human plasma with unprecedented sensitivity, as high as 104.51 ± 0.7 Hz·mM−1·cm−2 and a detection limit of 2.31 ± 0.3 mM. The results suggest the possibility to sense human plasma glucose at clinically relevant concentrations without the use of an external power source.

Objective-Clinical trials and observational studies have provided good evidence that early glycemic control leads to a reduction in complications and improved survival in diabetics. However, elevated risk of mortality has been reported at both the lower and upper ends of long-term glucose levels. Fear of hypoglycemia has been a significant factor in suboptimal glycemic control. In this retrospective analysis we aimed to identify the incidence of hypoglycemia and their precipitating factors in elderly diabetics on good glycemic control. Material and methods- Ninety seven elderly diabetic patients attending the cardiology Out-Patients Department of a super speciality private sector hospital from 1 December 2017 to 30 November 2018 were studied retrospectively. Their demographic profile, co-morbidities and pharmacological profile were recorded. Incidence of hypoglycemic episodes and their precipitating factor were then analyzed. Result-Mean age was 71.7± 6.3 years, and 64 (66%) were male. Mean duration of diabetes was 7.3± 1.3 years. All patients had type II diabetes mellitus. Mean fasting and random capillary blood glucose levels were 116.5 ±8.7 mg/dl and 169.5±13.5mg/dl, respectively. Mean HbA1c levels of the study population was 6.8±1.14. Over the study period, 23 (23.7%) patients experienced 39 episodes of any level of hypoglycemia. HbA1c Levels in the hypoglycemia group were not significantly different from those in no-hyperglycemia group (6.85±1.13 vs. 6.63±1.04). Mean random plasma glucose values were slightly higher in no-hypoglycemia group (170.9±14.5 vs 164.9±14.9), but the difference did not reach the statistical significance. There was a markedly significant difference in mean fasting plasma glucose values between hypoglycemia and no-hypoglycemia group (101.8±8.9 vs 116.5±12.7). Sulphonylurea and insulin use was more frequent in patients experiencing hypoglycemia (9.6% and 52.2% respectively) as compared with no-hypoglycemia group (33.8% and 39.1% respectively). The most common preceding event was either skipping a meal in 12(30.8%) patients or an unplanned change in diet in 23% patients. Conclusion- Patients with longstanding diabetes and loss of warning symptoms have increased risk of severe hypoglycaemic episodes. Risk of the hypoglycemic episode is better correlated with fasting plasma glucose levels and glycemic variability rather than with HbA1c Level. Sulphonylurea drug use was the only group associated with a statistically significant risk of hypoglycemia. Skipping of a meal or a sudden change in the diet and alteration in antidiabetic drug regimen are the most important precipitating factors for hypoglycemia.

In Mexico one in 14 deaths are caused by diabetes mellitus (DM) or by the macro and microvascular disorders derived from it. A continuous hyperglycemic state is characteristic of DM, resulting from a sustained state of insulin resistance and/or a dysfunction of β-pancreatic cells. Acaciella angustissima is a little studied species showing a significant antioxidant activity that can be used as treatment of this disease or preventive against the complications. The objective of this study was to explore the effect of oral administration of A. angustissima methanol extract on physiological parameters of streptozotocin-induced diabetic rats. The results indicated a significant reduction in blood glucose levels, an increase in serum insulin concentration, a decrease in lipid levels and an improvement in the parameters of kidney damage by applying a concentration of 100 mg/Kg B.W. However, glucose uptake activity was not observed in the adipocyte assay. Moreover, the extract of A. angustissima displayed potential for the complementary treatment of diabetes and its complications likely due to the presence of bioactive compounds such as protocatechuic acid. This study demonstrated that methanol extract of Acacciella angustissima has an antidiabetic effect by reducing the levels of glucose, insulin and improved physiological parameters, hypolipidemic effect, oxidative stress and renal damage in diabetic rats.

The Mean

Background In patients with chronic liver disease (CLD), glycated haemoglobin (HbA1C) levels have been shown to be apparently lower than real values, whereas serum glycated albumin (GA) levels are apparently higher. The present study was aimed to examine whether both glycaemic indices are influenced by hepatic function. Methods Subjects consisted of 82 patients with CLD. Various indicators for hepatic function as well as HbA1C and GA were also measured. Estimated HbA1C values were calculated from the mean plasma glucose levels. Two hundred and two type 2 diabetic patients without CLD were studied as controls. Results Although GA was strongly correlated with HbA1C in patients with CLD as well as diabetic patients, GA levels in patients with CLD were relatively higher than those in diabetic patients. In patients with estimated HbA1C ≤5.8%, GA levels significantly increased but HbA1C levels decreased as a function of decreasing hepaplastin test (HPT). The ratio of GA/HbA1C (G/H ratio) increased as a function of decreasing HPT. In patients with estimated HbA1C >5.8%, in contrast, GA levels were independent of HPT levels. In the patients with CLD, GA and HbA1C were associated with mean plasma glucose levels and some indicators for hepatic function. The multivariate analysis revealed a significant association of G/H ratio with HPT, cholinesterase and direct bilirubin. The G/H ratio was not associated with the mean plasma glucose but with HPT and cholinesterase levels. Conclusions The G/H ratio correlates with hepatic function but not with plasma glucose levels. Therefore, CLD should be suspected for diabetic patients with an elevated G/H ratio.
