Triple Trouble.

We present a case of a 24-year-old female recently diagnosed with acute leukemia who came with complaints of fever for 14 days, progressive lower limb weakness, and multiple episodes of vomiting in the last 1 day. In nerve conduction studies, a diagnosis of Guillain-Barré syndrome (GBS) was established. Fever with thrombocytopenia workup revealed a positive dengue nonstructural protein 1 (NS1) and immunoglobulin M (IgM) report. Immunophenotyping confirmed pre-B acute lymphoblastic leukemia (ALL). As leukemia is an immunocompromised state, the peripheral nervous system vulnerability is increased, or infection could precipitate an immune neuropathy. About 10% of adult ALL presents with central nervous system (CNS) leukemias; a higher incidence is seen in mature B ALL. There is some evidence to suggest immunosuppression secondary to intensive chemotherapy (vincristine-induced dying back neuropathy), which was not started in our case. This rare combination in a short period of time with a worsening situation paralyzed the line of management. Few reports described GBS in patients with dengue in adults. The association of Guillan-Barre syndrome and ALL could be coincidental or has a pathophysiological basis and is under basic investigation.

Stumbling Blocks to Stroke Thrombolysis: An Indian Perspective.

Background and purpose: Stroke is a leading cause of morbidity and mortality worldwide. Developing countries, however, still lag behind in providing timely thrombolytic therapy (TLT) to many eligible patients owing to various reasons. This study aims to identify such factors. Materials and methods: This was a descriptive observational study undertaken over a period of 18 months at a tertiary care teaching hospital and included 252 acute ischemic stroke patients of which 200 were not thrombolyzed. The reasons for nonthrombolysis were recorded and analyzed. Results: The study included 252 acute ischemic stroke patients of which only 20% were thrombolyzed. Of the 200 nonthrombolyzed patients, 55% arrived out of the window period while patient-related factors were the second biggest factor preventing thrombolysis. Hospital factors at 14% and financial constraints at 4.5% contributed significantly. Delayed consent emerged as an important factor making 6% of the delays. Conclusion: Stroke thrombolysis still faces various pre- and intrahospital barriers in India. There is an urgent need to improve infrastructure and organizational streamlining to enable eligible patients to receive prompt treatment. How to cite this article: Shah A, Diwan A.

Stroke Thrombolysis: Beating the Clock.

Background: Recombinant tissue plasminogen activator (rtPA) has revolutionized the management of acute ischemic stroke. Shorter door-to-imaging and door-to-needle (DTN) times are crucial for improving the outcomes in thrombolysed patients. Our observational study evaluated the door-to-imaging time (DIT) and DTN times for all thrombolysed patients. Materials and methods: The study was a cross-sectional observational study over a period of 18 months at a tertiary care teaching hospital and included 252 acute ischemic stroke patients of which 52 underwent thrombolysis with rtPA. The time intervals between arrival to neuroimaging and initiation of thrombolysis were noted. Result: Of the total patients thrombolysed, only 10 patients underwent neuroimaging [non-contrast computed tomography (NCCT) head with MRI brain screen] within 30 minutes of their arrival in the hospital, 38 patients within 30-60 minutes and 2 each within the 61-90 and 91-120 minute time frames. The DTN time was 30-60 minutes for 3 patients, while 31 patients were thrombolysed within 61-90 minutes, 7 patients within 91-120 minutes, while 5 each took 121-150 and 151-180 minutes for the same. One patient had a DTN between 181 and 210 minutes. Conclusion: Most patients included in the study underwent neuroimaging within 60 minutes and subsequent thrombolysis within 60-90 minutes of their arrival in the hospital. But the time frames did not meet the recommended ideal intervals, and further streamlining of stroke management is needed even at tertiary care centers in India.

Association of MTHFR C677T (rs1801133) and A1298C (rs1801131) Polymorphisms with Serum Homocysteine, Folate and Vitamin B12 in Patients with Young Coronary Artery Disease.

C677T (rs1801133) and A1298C (rs1801131) MTHFR gene polymorphisms and/or nutritional deficiency of folate/vitamin B12 leading to hyperhomocysteinemia is an established risk factor for CAD. The objective of this study was to evaluate the clinical usefulness of association between MTHFR C677T (rs1801133) and A1298C (rs1801131) polymorphisms with serum homocysteine, folate and vitamin B12 in addition to conventional cardiovascular risk factors in patients with young CAD. Genomic DNA was isolated from the whole blood. Genotyping of MTHFR C677T (rs1801133) and MTHFR A1298C (rs1801131) polymorphisms in young CAD patients and healthy controls was performed by ARMS-PCR method. Serum homocysteine, vitamin B12 and folate were estimated by CMIA and lipid profile parameters were measured by automated chemistry analyzers. Serum homocysteine levels were significantly higher but serum folate and vitamin B12 levels were not significantly different among young CAD group as compared to control group. Statistically significant hyperhomocysteinemia was observed in carriers of T allele for MTHFR 677C/T (rs1801133) genotype in young CAD group but this association was not significant for MTHFR 1298A/C (rs1801131) polymorphism. The association between hyperhomocysteinemia and CAD in young group was not independent of conventional cardiovascular risk factors. Risk of hyperhomocysteinemia and young CAD could be monitored by MTHFR polymorphism detection followed by serum homocysteine, folate and vitamin B12 measurements. The findings could help to prevent or delay the occurrence of young CAD through appropriate measures.

Plasma glycation adducts and various RAGE isoforms are intricately associated with oxidative stress and inflammatory markers in type 2 diabetes patients with vascular complications.

BACKGROUND: The secondary vascular complications in diabetes mellitus (DM) are contributed by acute as well as inflammatory responses which get activated due to interaction between glycation adducts and respective receptors. AIM: The present work was performed to understand the relationship between Advanced glycation end products (AGEs)-receptor for advanced glycation end products (RAGE) interaction with oxidative stress and inflammation in vascular complications. METHODS: For the present work we recruited 103 controls, 200 patients with type 2 DM, and 200 patients with Diabetic complications. Different Plasma glycation adducts (fructosamine, carbonyls, AGEs, ß-amyloid content, free amino groups, and free thiol groups); RAGE isoforms, level of antioxidant such as glutathione, catalase activity, nitric oxide level, total antioxidant capacity, and superoxide dismutase activity, as well as oxidative markers, and expression of Nε-carboxymethyl-lysine (CML), different isoforms of RAGE, NF-κB, and inflammatory markers were analyzed. RESULTS: Glycation adducts were higher in DM patients and more elevated in nephropathy patients where free amino groups and thiol groups lowered as compared to controls. sRAGE levels and expression were increased mainly in nephropathy. CML expression was higher in nephropathy patients. The antioxidant profile indicates a reduced level of different antioxidants while increased lipid peroxidation and intracellular ROS generation in DM and much higher in nephropathy patients. Expression of membrane RAGE, NF-κB, and inflammatory markers showed a remarkably increased level in DM patients with nephropathy. CONCLUSION: This work provides the first evidence of four different RAGE isoforms in diabetes and in complications. The glycation via the activation of RAGE, oxidative stress, and resultant inflammation plays a crucial role in the development of diabetic complications.

Safety and immunogenicity of inactivated hepatitis-A vaccine developed by Human Biologicals Institute in two age groups of healthy subjects: A phase I open label study.

BACKGROUND: Hepatitis-A is an acute viral infection of the liver. Hepatitis-A virus has worldwide spread and is endemic in India. Though the disease is self-limiting in most cases, outbreaks are reported frequently from both developing and developed countries of the world. Severity and fatality occur more among infected symptomatic adults. The infection can be prevented with proper and timely immunization. This phase I, single arm, open label, multicenter trial was designed to assess the safety and immunogenicity of the inactivated hepatitis-A vaccine developed by Human Biologicals Institute when administered in a single dose in two age groups of healthy subjects. METHODS: This study was carried out in 55 subjects in two healthy age groups at two centers in India. Group A included subjects of 19-49 years and group B subjects of 12-18 years of age. Enrolled subjects received a single dose of inactivated hepatitis A vaccine. Blood samples were collected at baseline and 4-6 weeks after vaccination. Safety was assessed by collection and analysis of data on solicited and unsolicited adverse events and immunogenicity was assessed by estimating the seroconversion rate, seroprotection rate and the geometric mean titres of antibodies. RESULTS: Among the 55 subjects enrolled, 15 reported adverse events. No serious adverse event was reported. Pain at the injection site was the lone local adverse event. Systemic adverse events reported in Group A were: fatigue, headache, diarrhoea, fever, anorexia, nausea and upper respiratory tract infection, whereas there was no systemic event reported in Group B. There was 100% seroconversion and seroprotection and significant rise in antibody titre levels were observed in both the groups post vaccination. CONCLUSIONS: This study found HBI inactivated hepatitis-A vaccine to be safe and highly immunogenic when administered as a single dose in adolescent and adult subjects.

Action of metformin therapy against advanced glycation, oxidative stress and inflammation in type 2 diabetes patients: 3 months follow-up study.

BACKGROUND: Persistence hyperglycemia results in the formation of advanced glycation end products (AGEs) by non-enzymatic glycation. AGEs and their receptor RAGE play an important role in generation of inflammatory molecules and oxidative stress. Metformin regulates insulin responsive gene and helps to achieve glycemic control however, no extensive study reported about its role against glycation induced oxidative stress and vascular inflammation. Therefore, present work focused on clinical relevance of three months metformin therapy in type 2 diabetes mellitus patients against glycation induced oxidative stress and vascular inflammation. METHODS: Among recruited 40 medicated-naive type 2 diabetes mellitus patients, 31 patients were continued with metformin therapy. Biomarkers of plasma protein glycation (fructosamine, protein carbonyls, ß-amyloid) antioxidants and oxidative stress markers (GSH, catalase, NO, PON-1, AOPP, LPO; RAGE isoforms (sRAGE, esRAGE); inflammatory markers (IL-6, TNF-α) were determined at baseline and after 3-months of treatment. The expression profile of membrane RAGE, NF-κB, CML was studied in PBMNCs and GLUT-1 in erythrocyte ghost by western blotting. RESULTS: Metformin showed maximum percent declined from baseline to three months therapy in levels of fructosamine, ß-amyloid, sRAGE, inflammatory cytokines (IL-6, TNF-α) and percent increment in esRAGE and antioxidants levels. It showed reduced levels of IL-6 and TNF-α by declining expression of CML, membrane RAGE and NF-κB in type 2 diabetes mellitus patients after three months therapy. CONCLUSIONS: First report in Indian diabetes mellitus patients, where metformin showed effective inhibition against glycation and receptor mediated cellular inflammation. However, these findings need to be tested in a randomized trial.

Gender dependent differences in lipid metabolism in individuals with type 2 diabetes mellitus.

AIM: The present study investigates gender dependent effects of insulin resistance on lipid profile and adipocytokines in individuals with diabetes receiving oral antidiabetic drugs (OADs). The aim was also to reveal the changes in the expression of genes involved in lipid metabolism and inflammation. METHODS: Lipid profile, adipocytokine levels and homeostatic model assessment of insulin resistance (HOMA-IR) was assessed in 100 patients with diabetes (M = 43, F = 57) matched for age and gender with healthy individuals (M = 45, F = 55). The expression pattern of genes was analyzed by quantitative real time PCR. RESULTS: Males consuming metformin with other drugs exhibited a positive association between HOMA-IR and cholesterol, triglyceride and very low density lipoprotein (VLDL). Females consuming only metformin and metformin with other drugs, showed a positive association of HOMA-IR with cholesterol and a negative association with adiponectin. In males and females with diabetes, a comparable expression of peroxisome proliferator activated receptor γ (PPARγ) while higher expression of sterol regulatory element binding protein 1 (SREBP1) was observed. Expression of fatty acid synthase (FAS), long chain acyl CoA Synthetases (ACSL), malonyl-CoA-acyl carrier protein transacylase (MCAT) and nuclear factor kappa ß (NFkß) was higher in men with diabetes than healthy males. Expression of tumor necrosis factor α (TNF-α) was higher in males and females with diabetes than respective healthy genders. CONCLUSION: Insulin resistance adversely affects lipid profile, adipocytokines in males with type 2 diabetes. Expression of genes involved in lipid metabolism and inflammation is found to be undesirably and differentially altered in both the genders.

Comparative study of different glycating agents on human plasma and vascular cells.

Diabetic complications are associated with the glycation and formation of advanced glycation end products (AGEs) which leads to structural modifications of biomolecules further affecting cells. Carbonyl compounds such as methylglyoxal and glyceraldehyde-3-phosphate are highly reactive and form an elevated amount of AGEs as compared to glucose and fructose. The investigation of glycation modifications by different compounds may be important to assess the specific pattern of biomolecular and cellular modifications and compare their glycation potential. The present work aims to comprehensively and comparatively examine the effect of glycating agents (glucose, fructose, ribose, methylglyoxal, and glyceraldehyde) on plasma, erythrocytes, platelets, and blood DNA. Glycation of plasma, cells, and DNA was initiated by incubating them with glycating agents for 24-48 h at 37 °C. Negative control samples (without glycating agents) were maintained simultaneously. After treatment, plasma and DNA samples were dialyzed and cell lysate was prepared. Markers of glycation (fructosamine), structural modifications (free amino, ß-amyloid, absorption spectra), antioxidant indices (catalase activity, glutathione) and erythrocyte hemolysis were estimated. In the presence of glycating agents, there was a significant increase in the formation of fructosamine, structural modification markers and depletion in antioxidant indices. Overall results suggest that among all glycating agents; methylglyoxal and glyceraldehyde have more potency of glycation induced structural modifications in plasma and vascular cells. This indicates the specific glycation modifications in plasma and vascular cells by various glycating agents may be investigated further for controlling diabetic pathological changes.

Correlation of Serum Adiponectin and Leptin levels in Obesity and Type 2 Diabetes Mellitus.

INTRODUCTION: Indian phenotype includes higher waist circumference despite lower body mass index, thereby making Indians more prone to diabetes and its complications. AIM: The present study aimed to analyze the serum levels of adiponectin and leptin in the participants with type 2 diabetes mellitus (T2DM) and obesity and their correlation with hypertension and dyslipidemia. MATERIALS AND METHODS: In the study, 50 diabetics and 50 controls aged between 40 and 60 years were included in the study. RESULTS: Adiponectin levels were significantly higher in diabetics than in nondiabetic participants irrespective of gender (P ≤ 0.04 in males, P ≤ 0.02 in females). Leptin levels were significantly higher in diabetics compared to nondiabetics (P ≤ 0.001) in both males and females. CONCLUSION: Adiponectin and leptin levels may be used as important clinical markers for T2DM and obesity.

Co-circulation of all the four dengue virus serotypes and detection of a novel clade of DENV-4 (genotype I) virus in Pune, India during 2016 season.

Dengue is the most common mosquito-borne viral infection in tropical and sub-tropical countries. In recent years, India has reported increased incidences of concurrent infection with multiple serotypes of dengue viruses (DENV). In the present study, we have characterized DENV circulating during a single season of 2016 in Pune, India. A total of 64 serum samples from NS1 ELISA positive dengue patients were used for PCR amplification of CprM region of the viral genome and sequencing. Phylogenetic analysis documented circulation of all the four DENV serotypes with predominance of DENV-2 (40.6%). DENV genotyping classified DENV-1 to Genotype V, DENV-2 to Genotype IV, DENV-3 to Genotype III and DENV-4 to Genotype I. Further analysis revealed emergence of a novel clade (D) of genotype I of DENV-4. Subsequent isolation of three DENV-4 viruses in cell culture followed by complete genome sequence analysis confirmed this observation. Additionally, a new genotype within serotype-4 with >6.7% sequence variation from other genotypes was identified. This first report of significant co-circulation of all the four serotypes in a single outbreak in Pune reconfirms need for molecular monitoring of DENV.

Azathioprine-Induced Pancytopenia and Septic Complications: A Probable Cause of Death.

Azathioprine, an immunosuppressant which is widely used in the management of the autoimmune neuromuscular disorder. Myasthenia gravis is known to cause myelotoxicity. A 55-year-old male recently diagnosed with myasthenia gravis and chronic kidney disease was put on azathioprine (100 mg/d) along with pyridostigmine and prednisolone. When the treatment was initiated, the hematological reports revealed normal levels of blood count. However, approximately within 3 weeks of continuing the prescribed drugs, the patient was readmitted for complaints of loose watery stools, weakness, and giddiness. Clinical investigations revealed severe pancytopenia, suspecting to be related to azathioprine. The suspected drug (azathioprine) was withdrawn, and the management for pancytopenia was initiated. However, on the second day of hospitalization, the patient underwent cardiac arrest and septic shock which lead to death. Adverse drug reaction assessment revealed a plausible and causal relationship of azathioprine with pancytopenia and other adverse effects seen in this patient.

Gender dependent effects of fasting blood glucose levels and disease duration on biochemical markers in type 2 diabetics: A pilot study.

AIM: The impact of fasting blood glucose levels (FBG) and disease duration on type 2 diabetes in Indian population is still unclear. The present study examines gender-dependent effects of FBG and disease duration on lipid profile, adipocytokines and related biochemical parameters in diabetic individuals. METHODS: Type 2 diabetic individuals (n=100) were classified depending on FBG: patients with normal FBG (Glucose<126mg/dl) and patients with high FBG (Glucose≥126mg/dl); and disease duration: ≥0-≤3yr, >3-≤7yr, >7yr. RESULTS: Males with high FBG had significantly higher serum glucose, triglycerides, very low density lipoprotein (VLDL), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and waist hip ratio (WHR) than males with normal FBG. Females with high FBG had significant increase in serum glucose, adiponectin and creatinine while decrease in leptin levels than females with normal FBG. Males with high FBG had higher WHR, superoxide dismutase, SGOT, SGPT and lower adiponectin, leptin than females with high FBG. Significant positive association was observed between glucose and cholesterol, triglyceride, VLDL and urea in males with high FBG. With chronic diabetes for >7yr, males had increased systolic blood pressure, glucose, LDL, urea and low catalase activity as compared to other disease duration groups. However, females had higher adiponectin, creatinine and lower body mass index and cholesterol. CONCLUSIONS: High FBG in males adversely affects lipid profile, adipocytokines and liver function. Some of these effects exacerbate as disease progresses. Higher adiponectin may have desirable effects on metabolic markers in females.

Adipocytokines and anthropometric measures in type 2 diabetics.

AIM: Type 2 diabetes mellitus has assumed pandemic proportions worldwide. Aggressive management of hyperglycemia in diabetics is a primary goal of treatment. We have previously reported favorable effects of oral hypoglycemic agents on adipocytokines. Aim of the present study was to investigate the relationship of adipocytokines with anthropometric measures and biochemical parameters in type 2 diabetics. METHODS: Clinically diagnosed type 2 diabetics and age, gender matched healthy volunteers were recruited for study. Anthropometric measurements like height, weight, waist-circumference, hip-circumference were recorded and BMI, waist-hip ratio were calculated. Fasting blood samples were collected from participants and sera were analyzed for glucose, glycated haemoglobin, total cholesterol, SGOT, SGPT, insulin, adiponectin and leptin. Correlation of adipocytokines with anthropometric and biochemical parameters was assessed in healthy and diabetic individuals. RESULTS: BMI and WHR in diabetics were significantly higher than healthy population. BMI did not show significant association with adipocytokines. Diabetic males with WHR≥0.9 showed negative association with adiponectin and positive association with leptin. WC did not show significant association with adipocytokines in males. Irrespective of WC, healthy females exhibited positive association with leptin. Diabetic females with WC≥88cm showed leptin to be positively associated with WC. Such association of adipocytokines with WHR was not detected in females. CONCLUSIONS: Body fat distribution can be considered as a parameter in assessing adipokine imbalance. Central adiposity is a better measure of adipokine imbalance than BMI. Abdominal obesity in diabetics correlates with altered levels of adipocytokines indicating its importance in diabetic individuals.

Relationship between plasma glycation with membrane modification, oxidative stress and expression of glucose trasporter-1 in type 2 diabetes patients with vascular complications.

BACKGROUND OF STUDY: Enhanced protein glycation in diabetes causes irreversible cellular damage through membrane modifications. Erythrocytes are persistently exposed to plasma glycated proteins; however, little are known about its consequences on membrane. Aim of this study was to examine the relationship between plasma protein glycation with erythrocyte membrane modifications in type 2 diabetes patients with and without vascular complications. METHOD: We recruited 60 healthy controls, 85 type 2 diabetic mellitus (DM) and 75 type 2 diabetic patients with complications (DMC). Levels of plasma glycation adduct with antioxidants (fructosamine, protein carbonyl, ß-amyloids, thiol groups, total antioxidant status), erythrocyte membrane modifications (protein carbonyls, ß-amyloids, free amino groups, erythrocyte fragility), antioxidant profile (GSH, catalase, lipid peroxidation) and Glut-1 expression were quantified. RESULT: Compared with controls, DM and DMC patients had significantly higher level of glycation adducts, erythrocyte fragility, lipid peroxidation and Glut-1 expression whereas declined levels of plasma and cellular antioxidants. Correlation studies revealed positive association of membrane modifications with erythrocyte sedimentation rate, fragility, peroxidation whereas negative association with free amino groups, glutathione and catalase. CONCLUSION: Our data suggest that plasma glycation is associated with oxidative stress, Glut-1 expression and erythrocyte fragility in DM patients. This may further contribute to progression of vascular complications.

Here we report a case of 58 year male with gastrointestinal complications of BD and a rapidly worsening course.

Diabetes and Complications: Cellular Signaling Pathways, Current Understanding and Targeted Therapies.

Diabetes is a metabolic disorder and over the past decades, it has become a major cause of morbidity and mortality affecting the youth and middle-aged as it is the fourth leading cause of disease related to death. In both type 1 and type 2 diabetes the severe pathogenesis cause micro vascular complications: nephropathy, retinopathy, neuropathy and macro vascular complications: cardiovascular disease, heart attacks and stroke. Under hyperglycemia, activation of different signaling mechanisms such as an increased polyol pathway, advanced-glycation end product formation, activation of Protein Kinase C and hexosamine pathway leads to the over expression of reactive oxygen species and causes pathogenesis of diabetic complications. It is necessary to understand these pathways in diabetic complications causing damage to the secondary system of the body. In the past decade the understanding of these biochemical changes has increased tremendously and various molecules have been exploited as therapeutic targets for diabetic complications as better therapeutic approach. In this review, a brief overview about diabetes mellitus and chronic complications with their current understandings of cellular/molecular mechanisms and targeted therapies along with novel therapeutic strategies is discussed.

Association of Fasting Plasma Glucose and Serum Lipids in Type 2 Diabetics.

Dyslipidemia is a significant morbidity associated with diabetes and cardiovascular disorders. The present study was undertaken to assess the lipid profile of type 2 diabetic and age-gender matched healthy subjects and its association, if any, with fasting plasma glucose. Clinically diagnosed diabetic subjects were recruited for the study. The fasting plasma glucose and lipid profiles were analyzed for 99 diabetic and 101 healthy volunteers. The blood samples were analyzed for fasting plasma glucose, total cholesterol, triglycerides, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol and very low density lipoprotein-cholesterol. Correlation analysis of lipid profile with fasting plasma glucose and calculation of risk ratio was done. The levels of high density lipoprotein-cholesterol and low density lipoprotein-cholesterol were found to be significantly low in diabetics and subjects with lower low density lipoprotein-cholesterol were on statins. Inspite of lower lipid values, the risk ratio for diabetics was significantly higher. The correlation analysis indicated significant difference in relationship between fasting plasma glucose, lipid parameters and risk ratios in the two groups. Diabetics with lower high density lipoprotein-cholesterol and higher total cholesterol present with a higher risk ratio pointing to need of non-statin high density lipoprotein-raising medications decreasing their predisposition to cardiovascular disorders. The study highlights the altered pattern of correlation of lipid profile with fasting plasma glucose in diabetics and their increased risk of cardiovascular disorders. The dyslipidemia in the form of triglyceridemia and significantly low high density lipoprotein-cholesterol in diabetics point towards the need of non-statin high density lipoprotein-raising medications.

Circulatory adipocytokines and lipid profile variations in type-2 diabetic subjects: desirable side-effects of antidiabetic drugs.

AIM: Inspite of availability of a variety of drugs to treat type 2 diabetes, little is known about their effects on other systems. Normalization of glucose metabolism by these drugs may consequently affect the secretory function in adipocytes. Secretory adipocytokines like adiponectin and leptin are emerging as novel therapeutic targets for type 2 diabetes mellitus (T2DM). The present study was undertaken to analyze the effects of commonly used Oral Hypoglycemic Agents (OHAs) alone, or in combination with other drugs and/or insulin on circulatory adiponectin and leptin levels, lipid profile, and blood pressure in diabetic subjects. METHODS: The study was undertaken at IRSHA and Bharati Vidyapeeth Medical College and Hospital, MS, India. Clinically diagnosed T2DM subjects and age, gender matched healthy controls were recruited. Fasting blood was collected from each subject and the blood samples were analyzed for circulatory adipocytokines and lipid parameters using commercial kits. RESULTS: Serum adiponectin levels were significantly increased while leptin significantly decreased in diabetic men (p<0.05) and women (p<0.001) on OHA, as compared to healthy controls. Triglyceride levels significantly decreased (p<0.05) in diabetic men, however, they remained unchanged in women despite same drug treatment. Serum HDL and LDL levels (p<0.001) were significantly lower in diabetic women as compared to healthy women. Systolic (p<0.05) and diastolic (p<0.001) blood pressure was significantly high in diabetic men but remained unchanged in women. CONCLUSIONS: Frequently used OHAs significantly improve circulatory levels of adipocytokines. Selecting best treatment option for each patient is a key, and 2012 European Association for the Study of Diabetes (EASD) and ADA guidelines recommend diabetes treatment to be individualized depending on various socioeconomic and lifestyle factors. We recommend regular analysis of circulatory adipocytokines in T2DM patients to help clinicians select the best treatment option to normalize levels of these important therapeutic targets.
