Association of Triglyceride and C-reactive Protein Level with Severity of Angiographically Defined Coronary Artery Disease.

Coronary artery disease (CAD) is considered as a major cause of morbidity and mortality worldwide. Inflammatory cytokines play an important role in the pathogenesis and progression of atherosclerosis. The aim of the study was to find out the association of C-reactive protein (CRP) and triglyceride (TG) level on the severity of CAD in patients with ischemic heart disease (IHD). This cross-sectional study was performed in the Department of Cardiology, National Institute of Cardiovascular Diseases, Dhaka, Bangladesh during the period of March 2018 to February 2021. Total 431 patients with ischemic heart disease were enrolled after taking informed written consent. CRP values were categorized into normal (<6 mg/L), borderline (6-10 mg/L) and high (>10mg/L) and TG level were categorized into normal (<150 mg/dl), borderline (150-199mg/dl) and high (≥200 mg/dl). Patients with ischemic heart disease (IHD) were stratified according to CRP value and TG level. Severity of CAD was assessed by the Gensini score. Most of the patients (33.4%) belonged to age 51-60 years. The mean age was 51.31±10.30 years. The majority (74.5%) of patients were male. Among risk factors, the highest 205(47.6%) patients were smokers followed by hypertension 190(44.1%) and diabetes mellitus 175(40.5%). The association of TG and CRP with the whole spectrum of IHD was found statistically significant (p<0.05). Severe CAD was found higher in high TG and high CRP level group compared with the other groups and was statistically significant. Inflammation assessed by high CRP and hypertriglyceridemia associated with the risk and severity of CAD.

Serum beta-N-acetylhexosaminidase, carcinoembryonic antigen & sialic acid in benign & malignant extrahepatic biliary obstruction.

Study of tumour markers to differentiate benign and malignant extra hepatic biliary obstructions showed that levels fo serum beta-N-acetylhexosaminidase and lipid associated sialic acid were not different in the two groups. The levels of carcinoembryonic antigen (CEA) and total sialic acid (TSA), on the other hand, were significantly higher in patients with the malignant biliary obstruction. At a cut-off value of 6.4 ng/ml (mean + 2SD) CEA had 66.7 per cent true positivity in malignancy 100 per cent true negativity in control and 78 per cent true negativity in the benign group. Similarly, TSA at a cut off value of 60 mg/dl had 61 per cent true positivity in malignancy, 90 per cent true negativity in controls and 70 per cent true negativity in the benign group. These two tumour markers appear to have similar diagnostic potential for malignant extrahepatic biliary obstruction. Surgical management of the malignant obstruction did not result in a decline in the elevated levels of these two markers during the post-surgical period of 7 days.

'Lennert's lymphoma' of the nose.

An 85-year-old male patient presented with a left-sided nasal obstruction of one year's duration. Histology of the tumour revealed cluster of epitheloid histiocytes scattered among immature lymphoid cells (lymphoblasts). Immunological studies of the tumour revealed a polyclonal (B cell) pattern in only a small proportion of the lymphoid cells. A T-cell origin is proposed. The histiocytes showed intense positivity when stained for muramidase. Wide local excision of the tumour was performed and the patient remains well and free of symptoms five months post-operatively.
