ABSTRACT
A multi-centred study was designed to collect dengue epidemiologic data from government and registered private hospitals/clinics and maintained archive of frozen specimens in bio-bank to be used for future dengue epidemic control program, and assess the epidemiology of dengue fever (DF) by evaluating biochemical and oxidative status of patients. ELISA IgM antibodies test was done to confirm DF. From August 2010 to December 2011, 101 confirmed blood samples of DF patients referred to pathology lab of Jinnah Hospital Lahore were subjected to the epidemiologic assessment by evaluating the biochemical and physiological indices and alterations of circulating antioxidants. Clinical features of DF patients and effect of fever on blood components and serum proteins of liver were recorded. The hospital stay in DF, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) showed significant difference. Significant increases in serum alanine amino transferase (ALT) (P=0.000), aspartate amino transferase (AST) (P=0.000), alkaline phosphatase (ALP) (P=0.000), malondialdehyde (MDA) along with significant decreases in total protein (TP) (P=0.000), reduced glutathione (GSH) (P=0.000), superoxide dismutase (SOD), catalase (CAT) (P=0.000), and sialic acid contents (P=0.016) were observed. A positive correlation existed between bound sialic acid levels, liver enzymes and circulating antioxidants (r=0.656, P=0.016). In the present study, alterations of circulating antioxidants in DF suggest that DF might be a metabolic response to an acute, self-limiting tropical viral infection, and a consequence of the viral inflammatory process.

Oral squamous cell carcinoma [OSCC] is considered to be a serious life threatening issue for almost two decades. The objective of this study was to evaluate the over production of lipid peroxidation [LPO] byproducts and disturbances in antioxidant defense system in the pathogenesis of oral cancer. Lipid peroxidation and antioxidant status in OSCC patients were estimated and compared the sensitivity and specificity of circulating biomarkers [MDA, Sialic acid, Catalase, SOD, GSH and Neuraminidase] with B-2 microglobulin [B-2MG] at different thresholds in blood and saliva using receiver operating characteristics [ROC] curve design. Our results showed that the levels of MDA and Sialic acid were significantly increased in plasma of OSCC patients as compared to healthy subjects whereas antioxidant level was significantly decreased. ROC analysis indicated that MDA in saliva is a better diagnostic tool as compared to MDA in blood and B-2MG in blood is better diagnostic marker as compared to B-2MG level in saliva
ABSTRACT
Objective: The Urticaria caused by NSAIDs wasstudied for their antioxidant enzyme activity andmalondialdehyde [MDA] concentration
Methodology: Patients were divided into twogroups; group one act as a control and the remaininggroup was urticaria patients. The levels of theThiobarbituric acid reactive substances [TBARS, asa marker of lipid peroxidation], superoxidedismutase [SOD], glutathione [GSH] and catalase[CAT] in the serum were estimated. The enzymaticactivity was estimated and compared with differentcategories of NSAIDs
Results: In present studyCAT, SOD and lipid peroxidation product [MDA]were statistically different from that of healthycontrol and showed significant changes [p< 0.05]while GSH showed a non-significant [p>0.05]value
Conclusion: It is concluded thatantioxidative system of the body is accelerated andshows variations in the patient of Urticaria.Moreover, present study shows the co-ordinatedenzymatic mechanism and the interrelationshipbetween enzymatic activities in allergy
