Prevalence of elevated liver enzymes and its relationship with type 2 diabetes mellitus in North Indian adults.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) also referred as metabolic as metabolic (dysfunction) associated fatty liver disease. Type 2 diabetes mellitus (T2DM) is a major cause in progression of NAFLD and non-alcoholic steatohepatitis (NASH). The aim of the present study is to assess the activity of liver enzymes in T2DM in North Indian population. METHOD: This was a cross-sectional descriptive study clinic-based study in patients with T2DM. A total of 612 participants (226 healthy controls and 386 T2DM) were recruited. Body mass index (BMI), activity of liver enzymes including alanine and aspartate aminotransferase (ALT, AST) along with alkaline phosphatase (ALP) was measured. Fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c) along with total protein (TP) and albumin were also measured. Quantitative variables were expressed as mean ± SD, while qualitative variables as frequencies (%). Pearson/Spearman correlation test, unpaired t-test, Chi-squared test was used to assess the correlation, association and significant differences between study groups respectively. A P-value of < .05 was set as statistically significant. The Statistical Package for Social Sciences (SPSS) ® Statistics, version 23 (IBM SPSS Statistics, Armonk, NY) was used to for analysis of data. RESULTS: The study was conducted on 386 T2DM patients, and out of 386 patients, 139 (36.01%) were male (P < .000) and 247 (63.98%) were female. The mean age of the T2DM patients was 46.4 ± 13.6 years, while healthy individuals have mean age of 39.2 ± 12.0 years (P < .000). It was observed that the activity of AST in T2DM is comparable with the healthy persons (P = .060). While the level of ALT, total bilirubin and ALP in T2DM is significantly higher compared to healthy control (P < .000). On average, 62.53% of T2DM subjects and 32% of participants of healthy subjects had abnormal liver enzymes activity. CONCLUSION: The present study has revealed widely co-existent derangements in liver function tests (LFTs) in the diabetic population of North India. A detailed workup in such patients may be helpful in timely diagnosis and treatment. Moreover, early detection and management of abnormal liver parameters in T2DM would help minimize liver-related morbidity and mortality.

Protein creatinine index: A possible predictor of nephropathy in hypertensives, in Northern India.

BACKGROUND: >33% of the hypertensive Indians develops nephropathy. Proteinuria is an early indicator of nephropathy. Gold standard for determining proteinuria is 24-hour urinary protein excretion which is a troublesome task with poor patient compliance. Protein creatinine index (PCI) in a random urine sample has been advocated by some researchers as an alternative approach. Aim of this study was to evaluate the association of PCI with the severity and duration of hypertension, in North Indian population. METHODS: 120 Stage-1 hypertensives, 120 stage-2 hypertensives, 40 pre-hypertensives and 40 normotensives were included in this study. 240 Hypertensive subjects were divided into 3 sub-groups based on duration: <5years (n=80), 5-10years (n=80) and >10years (n=80). Urinary protein was estimated by sulfosalicylic acid method and urinary creatinine was measured using modified Jaffe's method. PCI was measured as described by Shaw et al. Data was statistically analyzed by ANOVA and Pearson's correlation test using SPSS v20. RESULTS: PCI of stage-2 hypertensives (157.83±51.53) was significantly higher than normo-, pre- and stage-1 hypertensives. PCI of stage-1 hypertensives (134.15±46.04) was significantly higher than normotensives only. PCI of hypertensives for 5-10years (137.29±49.55) and >10years (181.85±47.42) was significant higher than controls and pre-hypertensives. PCI showed significantly stronger association with severity (r=0.595) and duration (r=0.745) of hypertension as compared to urinary protein and creatinine concentration. Data also suggest that the risk of renal injuries against the backdrop of raised blood pressure (BP) increases after 5years of hypertension. CONCLUSION: PCI can be used as a screening tool for early detection of hypertensive nephropathy. PCI monitoring should be incorporated in the routine checkup module of patients suffering from hypertension for >5years.

Study of Electrophysiological Changes in Sensory Nerves Among Diabetic Smokers.

INTRODUCTION: Neuropathy is one of the most troublesome complication affecting individuals with diabetes. The resultant loss of function in peripheral nerves causes loss of protective sensations and impairs patient's ability to perceive incipient or even apparent ulcerations in the feet. AIM: This study was undertaken to test the hypothesis of alteration in electrophysiological parameters of nerve before actual manifestations of neuropathy in type 2 diabetic patients and to analyse the effect of smoking on Sensory Nerve Conduction Velocity (SNCV) of diabetic subjects. MATERIALS AND METHODS: One hundred and twenty diagnosed diabetics were taken as cases while 30 healthy non diabetics were taken as control. Case group was divided into diabetic non-smoker and diabetic smoker. Diabetic smoker were further subdivided into light smoker, moderate smoker and heavy smoker according to smoking index. After detailed history and physical examination SNCV of median and ulnar nerve in upper limb and sural nerve in lower limb was performed. RESULTS: On comparison of SNCV of median and ulnar nerve of upper limb and sural nerve of lower limb between control and diabetic non-smoker only sural nerve of diabetic non smoker showed significant bilateral decrease. There was significant bilateral decrease in SNCV of median and ulnar nerve of diabetic heavy smoker when compared to control and diabetic non smoker. Similarly, SNCV of sural nerve of diabetic heavy smoker was significantly decreased when compared with control, diabetic non-smoker, diabetic light and moderate smoker. A negative and statistically significant correlation was found between SNCV and smoking index. CONCLUSION: Present study indicates that nerves of lower limbs are more susceptible to diabetic assault as compared to upper limb suggesting that long nerves are commonly affected. Also, apart from duration and severity of diabetes, smoking itself is an independent factor for diabetic neuropathy.

In vitro antioxidant and in vivo hepatoprotective activity of leave extract of Raphanus sativus in rats using CCL4 model.

BACKGROUND: Raphanus sativus is reported to have a variety of biological activities. This work screened the hepato-protective and antioxidant activity of ethanol (ERS), and aqueous (ARS), extracts of leaves of Raphanus sativus in Carbon tetrachloride (CCl4), model in rats. MATERIAL AND METHODS: The extracts were subjected to antioxidant tests (Total reducing power and Total phenolic content), and preliminary phytochemical screening. A pilot study was done on 100 and 300 mg/kg extracts, form which 300 mg was chosen for further experiments. The albino rats (200-250 grams), were divided into 5 groups of 6 animals each (n=6). There were three control groups comprising of normal control (normal saline -1ml/kg), negative control group (CCl4 1ml/kg in olive oil in a ratio of 1:1 v/v), and positive control group (Silymarin 50mg/kg). The Test drugs were given in a dose of 300 mg/kg for both ERS and ARS extract for 7 days. Biochemical parameters (AST, ALT, Alkaline phosphatase, Total Bilirubin), histo-pathological examination of liver and in vivo antioxidant tests [CAT, GSH and MDA] were done. RESULTS: The phytochemical study showed the presence of flavanoids, terpenoids, alkaloids, saponins and sterols. A dose dependent increase in the oxidative potential was observed in both the extracts with total phenolic content 70.1 and 44.4 GAE/g extract for ERS and ARS respectively. ERS 300mg/kg showed a significant (p<0.001) increase in levels of AST, ALT and alkaline phosphatase as compared to negative control (percentage hepatoprotection =45.3%) while ARS 300 mg/kg (p<.01) group showed 30% hepatoprotection. The GSH (p<0.001) and CAT (p<0.05) in ERS and ARS were significantly increased while MDA levels were decreased (P< 0.01), as compared negative control. The findings were confirmed histo-pathological examination. CONCLUSION: The ethanol and aqueous extract of Raphanus sativus have partial hepatoprotection against CCl4 toxicity.

Alpha-1 antitrypsin, a diagnostic and prognostic marker of vernal keratoconjunctivitis.

INTRODUCTION: A major chunk of ocular allergies in humans involve the conjunctiva, of which Vernal Keratoconjunctivitis (VKC) appears to be more common. VKC, a chronic allergic conjunctivitis, frequently affects young males and is characterized by intense inflammation of the limbal and/or tarsal conjunctiva. The etiology and immuno-pathogenesis of VKC still remain unclear. Alpha-1 antitrypsin (AAT), a member of serine proteinase inhibitor (SERPIN) superfamily, is an acute phase protein whose concentration in blood increases in response to inflammation. AAT deficiency is one of the many factors that may be involved in several abnormalities such as liver disease, emphysema, inflammatory joint diseases and inflammatory eye diseases. In the present study, the role played by this protein in VKC was analyzed in a selective case/control study to assess its diagnostic and prognostic value. MATERIALS AND METHODS: The case control study included 50 patients of VKC reporting to Ophthalmology out patient department (OPD). Age and sex matched 40 healthy subjects served as control. Serum AAT level of both the cases and controls were evaluated and compared. Moreover the serum AAT levels of the patients at presentation were compared with their serum AAT level after three weeks post treatment. RESULT: Levels of AAT in the serum of VKC patients at presentation (2.80 ± 0.42 mg/ml) were significantly higher as compared to controls (2.31 ± 0.21 mg/ml) whereas no significant difference was observed between the serum level of post treatment VKC patients (2.48 ± 0.26 mg/ml) and controls. CONCLUSION: AAT is a potent acute phase protein whose concentration rises significantly in VKC, irrespective of the age and sex of the patient. Moreover, the serum level of AAT declined significantly post treatment; therefore it might be used as a prognostic marker.
