ABSTRACT
Chronic obstructive pulmonary disease (COPD) is a systemic inflammatory condition, the earliest manifestation of which is airway obstruction which is only partially reversible and the treatment rationales are provided accordingly. Research has shown that COPD-inflammation involves multiple inflammatory cells and mediators and the underlying pathology differs from asthma inflammation.For these reasons, therapeutic agents that are effective in asthma patients may not be optimal in COPD patients. COPD exacerbations are intensified inflammatory events compared with stable COPD. The clinical and systemic consequences believed to result from the chronic inflammation observed in COPD, suggest that inflammation intensity is a key factor in COPD and exacerbation severity and frequency. Although inhaled corticosteroids are commonly used and are essential in asthma management, their efficacy in COPD is limited, with only a modest effect at reducing exacerbations. The importance of inflammation in COPD needs to be better understood by clinicians, and the differences in inflammation in COPD versus asthma should be considered carefully to optimize the use of anti-inflammatory agents. Current COPD management focuses predominantly on symptom relief by optimizing bronchodilatation. The role of phosphodiesterase type 4 inhibitors (PDE4), statins, angiotensin converting enzyme inhibitors, theophylline and tumor necrosis factor inhibitors in COPD management will be reviewed. Targeting COPD inflammation with the goal of reducing exacerbations is a major focus of current clinical practice & outcome research.
ABSTRACT
Upper GI bleeding is a common medical emergency with a significant mortality, outcome of which depends upon the cause, appropriate and early intervention in a specialized center. This study was carried out to see the outcome of patient with Upper GI haemorrhage. Fifty cases with episode of upper gastrointestinal haemorrhage, admitted into medicine units of Faridpur Medical College Hospital from January 2011 to December 2011, were studied. Duodenal ulcer was the commonest cause of haematemesis and melaena followed by oesophageal varices, gastric ulcer and erosive gastritis. The peak incidence was among 35 to 45 years of age. Over all male female ratio was 4.55:1 but in case of duodenal ulcer it was 9:1. During hospital stay recurrent bleeding was noted in 10% of patients and during subsequent follow up it was 10% of the total and 50% in case of variceal bleeding group. Over all hospital mortality was 4% .
ABSTRACT
Type 2 Diabetes Mellitus (T2DM) is a complex disease with the co-existence of several pathophysiological abnormalities. Both microvascular and macrovascular complications are the main causes of morbidity and mortality, which develops due to endothelial dysfunction. Upregulation of reactive oxygen species, chronic inflammatory and hypercoagulable states are the pathologic basis of vascular dysfunctions in T2DM. To overcome all these abnormalities, different classes of antihyperglycaemic agents have developed. Unfortunately none is able to show satisfactory glycaemic control and to modulate vascular dysfunction. Incretin hormones are secreted from intestine during meal, which enhance insulin secretion and inhibit glucagon secretion from the pancreas. The incretin effect is severely reduced or absent in T2DM. Incretin-based new antidiabetics, both Dipeptidyl Peptidase-4 (DPP-4) inhibitors (Saxagliptin, Sitagliptin, Vildagliptin) and Glucagon Like Peptide-1 (GLP-1) analogs (Exenatide) are now being used globally. They are almost equally effective as conventional antidiabetics like Sulphonylureas (SU), Metformin (MET), Thiazolidinediones (TZD) and insulin when given as monotherapy or combined with SU, MET or TZD as second line agent. Incretin-based agents do not cause hypoglycaemia, produce weight loss in spite of weight gain and do not retain salt or water and almost no gastrointestinal (GIT) symptoms. The agents correct vascular dysfunctions and dyslipidaemia and can be given in elderly and renal impaired patients.
