Expert Opinion: Use of sodium glucose co-transporter type-2 inhibitors in South Asian population -The Pakistan perspective.

Sodium-glucose co-transporter type 2 inhibitors (SGLT 2- i)are increasingly being used in the management of type 2 diabetes mellitus (T2DM). With the novel insulinindependent glycosuric action, these agents help to attain glycaemic goals by lowering HbA1c and fasting blood glucose. In addition, these agents improve metabolic control in diabetes and ameliorate comorbidities like obesity and hyper tension. Beneficial effec ts on cardiovascular outcomes have been a key attraction for physicians. These agents are used alone or in combination with oral antidiabetic agents and insulin to attain glycaemic and metabolic targets. A major disadvantagewith these agents is the increased risk for genital andurinary infections. When used in appropriate settings, there is no additional increased risk of hypoglycaemia or volume depletion with these agents. Available evidence suggests good efficacy and safety of these agents in diabetes management. The easy and convenient oncedaily dosing should be customized according to patient needs and glycaemic profiles.

Assessment of biochemical and antioxidative status in patients suffering from dengue fever.

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.

New possibilities in hepatocellular carcinoma treatment.

Hepatocellular carcinoma diagnosis and treatment has witnessed many major changes and challenges in the past two decades. Increasing incidence of HCC has introduced new monitoring systems and increased the efficacy of screening tests, as well as prognosis of the disease, including the staging system, serological testing and diagnostic imaging. Moreover, surgical resection, liver transplantation and herbal therapy have improved treatment. The most encouraging specific serological marker for HCC is alpha fetoprotein (AFP), which, along with ultrasonography, has improved earlier detection of HCC. Most recently, circulating tumor cell measurement has emerged as a promising tool for the prognosis of HCC. Herbal drugs and herbal composite formula drugs are promising towards the prevention of invasion and proliferation of tumor cells. Chemotherapeutic agents, such as sorafenib, bevacizumab and erlotinib, which target growth factor receptors in signaling pathways, are also used as HCC treatments. Furthermore, radiotherapy is employed in the treatment of unresectable tumors. The present report provides an analysis of the above parameters in the management of HCC.
