Evaluation of Inflammatory Markers and Demographic Profile of Type 2 Diabetes Mellitus Patients among the Ethnic Communities Attending Central Referral Hospital, East Sikkim.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is the most common metabolic disorder and inflammation plays a key role in the pathogenesis of the disease. Ethnic variations have been linked with an increased prevalence of diabetes. This pilot study was designed to evaluate the inflammatory markers and demographic characteristics in T2DM patients among the ethnic group of Sikkim. MATERIALS AND METHODS: A total of 100 type 2 diabetic patients and 50 healthy controls were enrolled in the study. Demographic characteristics were recorded among the patients and inflammatory markers [high sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6)], body mass index (BMI), glycemic status, fasting blood sugar (FBS), and postprandial blood sugar (PPBS) level were compared between the cases and controls. Inflammatory markers were correlated with BMI, glycemic status, and duration of diabetes. RESULTS: Type 2 diabetes mellitus was found to be highest in between the age-group of 45 and 55 years with males being mostly affected. Among the ethnic group, Nepalis (57%) comprised the highest with diabetes. No significant correlation was found between inflammatory markers with BMI, glycemic status, and duration of diabetes. CONCLUSION: Our study showed that T2DM increases as age progresses with males being mostly affected. The Nepalese community showed a high proportion of the disease mostly living in the urban residences. Though we included patients on statin therapy, its specific roles and relationship were not in the scope of the current study, but further studies should be conducted at the community level to understand the role and relationship of statins among type 2 diabetic patients and the possibilities of ethnic differences in the levels of biomarkers due to variation in the body fat distribution.

Prevalence of refractive errors among the school-going children in East Sikkim.

Purpose: Vision plays an important role in child's development for learning and communication. Uncorrected refractive error (URE) has become a major challenge to health care policy makers especially in school going children. We aim to report the prevalence of refractive error among the school students of the east district of Sikkim, India. Methods: A cross-sectional study was carried out among 15,954 school children under school health program of national program for control of blindness. The screening was conducted in 40 schools of east district which included primary, higher secondary, monastic and private schools. Results: The prevalence of refractive error was 6.7% among which myopia was the most common error present in 335 (31.1%) children, followed by astigmatism in 317 (29.4%) and the remaining 29 (2.6%) with hyperopia. The age group between 14-17 years had high prevalence of refractive error (9.2%). Females had slightly higher refractive error (6.93%) than males (5.9 %). Most backward classes were found to be highest suffering from refractive error (26.65%) and the least seen was found in schedule tribe (11.6%). Conclusion: The study provides a useful and baseline data about the refractive error amongst the school children of east Sikkim. A larger study needs to be conducted in all the schools of the state to get a clearer picture of RE and other eye related diseases to detect vision problem as early as possible.

Correlation of cartilage metabolic markers & antioxidants with the severity of knee osteoarthritis.

Osteoarthritis is characterized by the degeneration of articular cartilage. Cartilage metabolic markers have been explored as possible markers for osteoarthritis, and osteogenic protein -1 (OP-1) has emerged out to play a major role in cartilage repair. Oxidative stress has been implicated as a mediator of cartilage damage in patients with osteoarthritis. The aim of this study was to correlate the cartilage metabolic markers and antioxidants with the severity of knee osteoarthritis.

Production of a polyclonal antibody against osteogenic protein-1, and its role in the diagnosis of osteoarthritis.

INTRODUCTION: Osteoarthritis (OA) is a progressive degenerative disorder of the articular cartilage. Available diagnostic radiography has been poorly associated with the progress and severity of this clinical disease. As osteogenic protein-1 (OP-1) has been identified as a bone morphogenetic protein with a major role in cartilage repair, we aimed to evaluate its potential role in the diagnosis of OA. METHODS: This was an experimental study conducted at the Department of Biochemistry, Sikkim Manipal Institute of Medical Sciences, India. Polyclonal antibodies (i.e. anti-OP-1[f]) were raised against OP-1 in mice, and subsequently used in a sandwich enzyme-linked immunosorbent assay (ELISA) to detect the presence of OP-1 in the synovial fluids of 75 osteoarthritic patients. For the purpose of correlation, the radiographic assessments of the knees of the 75 patients were graded using the Kellgren-Lawrence scoring system. RESULT: The polyclonal antibody (i.e. anti-OP-1[f]) raised against OP-1 was able to detect the presence of OP-1 in the synovial fluids of all the osteoarthritic patients via sandwich ELISA. The level of the OP-1 was found to be much higher than the reference range and correlated positively with the severity of OA (r = 0.24; p = 0.04). CONCLUSION: Our study shows that the polyclonal antibody, anti OP-1(f), could be used for the immunodiagnosis of osteoarthritis via sandwich ELISA.

Correlation of the Osteogenic Protein-1 (OP-1) with Age, Cartilage metabolic Markers and Antioxidants in the Osteoarthritic Patients of Sikkim.

BACKGROUND: Age and oxidative stress have been implicated as the main causes of the cartilage damage in osteoarthritis (OA). The osteogenic protein-1(OP-1), a member of the bone morphogenetic family (BMP), plays a major role in cartilage repair. AIM: To correlate the OP-1 in the synovial fluid with the age and antioxidants like superoxide dismutase (SOD), glutathione peroxidase (GPx) and uric acid (UA) in the blood and with the cartilage metabolic markers like hyaluronic acid (HA) and keratan sulphate (KS) in the synovial fluid of osteoarthritic patients. METHOD: Seventy five osteoarthritic patients were taken up for the study. Heparinized blood samples were collected for the estimation of SOD, GPx and UA. Synovial fluid was aspirated for the estimation of HA, KS and OP-1. OP-1 was estimated by using a polyclonal antibody (anti-OP-1) which was produced against OP-1 in the mouse ascitic fluid by sandwich ELISA. RESULT: Age and UA showed a significant correlation with OP-1. On the other hand, the correlations between OP-1 and the antioxidants (SOD and GPx) and the cartilage metabolic markers (HA and KS) were insignificant in osteoarthritic patients. CONCLUSION: The study suggests about the important role of OP-1 in cartilage aging and degeneration, which may help us in understanding the potential for the therapeutic interventions in the treatment of cartilage degenerative processes.
