Significance of serum ferritin and De Ritis ratio in non-alcoholic fatty liver disease as diagnostic markers.

Objectives: To ascertain the significance of serum ferritin and De Ritis ratio as diagnostic markers in patients of nonalcoholic fatty liver disease with and without type 2 diabetes mellitus. METHODS: The comparative cross-sectional study was conducted from February to October 2022 at the Radiology Department of Combined Military Hospital, Rawalpindi, Pakistan, and comprised individuals aged 30-65 who were divided into 3 groups. Healthy controls formed group I, non-alcoholic fatty liver disease patients without type 2 diabetes mellitus formed group II and non-alcoholic fatty liver disease patients with type 2 diabetes mellitus were in group III. Blood 5ml was withdrawn and assessed for alkaline phosphatase, aspartate transaminase, alanine transaminase and ferritin. De Ritis ratio was calculated and subjected to intergroup comparison. Data was analysed using SPSS 22. RESULTS: Of the 210 subjects, 110(52.4%) were males and 100(47.6%) were females, with 70(33.3%) in each of the three groups. Group I had 38(54.3%) females and 32(45.7%) males with mean age 37.50±4.513. In group II, there were 27(38.6%) females and 43(61.4%) males with mean age 45.86±9.646, while in group III there were 35(50%) females and 35(50%) males with mean age 54.01±9.243 years. Serum ferritin levels were significantly increased in patient groups II and III compared to control group I (p<0.05). De Ritis ratio was markedly raised in groups II and III compared to group I (p<0.05). Ferritin was significantly correlated to age, weight, height, fasting blood glucose, haemoglobin, alkaline phosphatase, aspartate aminotransferase, alanine transaminase and bilirubin (p<0.05). De Ritis ratio had a significant correlation with body mass index and fasting blood glucose (p<0.05). CONCLUSIONS: Serum ferritin and De Ritis ratio were found to be useful diagnostic indicators for non-alcoholic fatty liver disease, highlighting their importance in improving disease screening.

Oxidative Stress and Lipid Peroxidation in NAFLD with and without Type 2 Diabetes Mellitus.

OBJECTIVE: To compare superoxide dismutase 1 (SOD 1) and malondialdehyde (MDA) levels along with biochemical parameters in patients of non-alcoholic fatty liver disease (NAFLD) with and without Type 2 diabetes mellitus. STUDY DESIGN: Cross-sectional comparative study. Place and Duration of the Study: Centre for Research in Experimental and Applied Medicine, AMC, in collaboration with the Department of Radiology, Combined Military Hospital, Rawalpindi, from February to November 2022. METHODOLOGY: Two hundred and ten patients were selected by non-probability purposive sampling and divided into 3 groups. Healthy individuals were labelled as Group Ι, Group II included patients of NAFLD without diabetes mellitus, and Group III had patients of NAFLD with diabetes mellitus. Fasting blood glucose levels and lipid profile were measured. ELISA (enzyme-linked immunoassay) was done for the assessment of SOD 1 and MDA levels. The data was analysed by version 22.0 of SPSS and expressed in mean ± SD and percentage. One-way ANOVA was done for all groups and grade comparison was followed by the post-hoc Tukey test. RESULTS: When compared to control groups, the mean SOD 1 level in diseased groups was significantly lower (p<0.001). There was a statistically significant difference between each group (p<0.001). Mean levels of MDA were significantly increased in diseased groups as compared to controls with a statistically significant difference between all groups except between Group II and III. CONCLUSION: In patients having NAFLD with and without diabetes mellitus, SOD 1 levels were considerably lower compared to controls whereas MDA levels were significantly higher. This decrease in SOD 1 and raise in MDA levels was indicative of increased oxidative stress in patients and can be viewed as a biomarker for oxidative stress. KEY WORDS: NAFLD, ELISA, Oxidative stress, SOD 1, MDA, Lipid peroxidation.

A Comparative Analysis of Superoxide Dismutase 1 Level in Diabetics with and without Neuropathy.

OBJECTIVE: To compare superoxide dismutase 1 (SOD1) levels in diabetes mellitus patients with and without neuropathy. STUDY DESIGN: Cross-sectional comparative study. PLACE AND DURATION OF STUDY: Multidisciplinary Lab-1 of the Department of Biochemistry and Molecular Biology, Army Medical College, in cooperation with Pak-Emirates Military Hospital, Rawalpindi, Pakistan, from January 2020 to January 2021. METHODOLOGY: Eighty-four subjects were enrolled through non-probability purposive sampling technique. They were further divided into three groups. Patients with diabetic neuropathy were labelled as the group Ι, and patients with diabetes mellitus without neuropathy were included in group ΙΙ. While group ΙΙΙ was comprised of healthy individuals and taken as control. Biochemical parameters included fasting blood glucose levels and HbA1c. Superoxide dismutase-1 levels were measured by enzyme-linked immunosorbent assay (ELISA). Data were evaluated by SPSS version 22.0 and presented in percentage and mean ± standard deviation (SD). Independent sample t-test and one-way ANOVA followed by the post-hoc Tukey test were used for group comparison. RESULTS: Mean level of SOD1 was significantly higher in group Ι as compared to group ΙΙ and ΙΙΙ (p<0.001). Statistically significant difference was observed among groups Ι and ΙΙ (p=0.002), Ι and ΙΙΙ (p<0.001), and ΙΙ and ΙΙΙ (p=0.017). Mean levels of SOD1 were also significantly increased with poor glycemic control (p<0.001). CONCLUSION: SOD1 level was considerably high in patients with diabetes mellitus with neuropathy in comparison to diabetics without neuropathy and healthy individuals. Key Words: Diabetes mellitus, Diabetic neuropathy, ELISA, Superoxide dismutase 1(SOD1).

Comparison Of Protective Effect Of Green Tea And Vitamin C Against Cypermethrin Induce Nephrotoxicity In Mice.

BACKGROUND: Insecticide toxicity is the problem of every person in under developed countries. It is necessary to counteract its effect by natural and cheap remedies like green tea and vitamin C. In this manner common man can also enjoy blessings of life. The current research was performed to compare the protective function of green tea and vitamin C on experimental cypermethrin provoked nephrotoxicity. METHODS: Forty healthy Balb/C mice purchased from National Institute of Health, Islamabad, Pakistan and divided in to four groups (10 each). Group a was control which received only normal diet. Group B, group C and group D were experimental groups which were given Cypermethrin, Cypermethrin with green tea and Cypermethrin with vitamin C respectively. These groups were also given normal diet. After 1 month blood was drawn by intra-cardiac method to assess renal parameters. RESULTS: One month research showed increase in serum urea to 6.8±.48 m.mol/l (n=3.9±.44) while green tea and vitamin C normalize them to 4.0±.83m.mol/l and 3.4±.33m.mol/l respectively. Serum creatinine increased to 42.90±3.28m.mol/l (n=29.50±3.95) while green tea and vitamin C normalize them to 28.80±4.58m.mol/l and 22.60±2.06m.mol/l correspondingly. CONCLUSIONS: The results showed that green tea and vitamin C neutralized toxicity induced by Cypermethrin in mice and their effect is comparable.
