Role of Immunological Method of Fecal Occult Blood Test for Screening Colorectal Diseases

Background: Colorectal diseases specially colorectal carcinoma is one of the major health problems throughout the world. Therefore, early diagnosis of these diseases is mandatory. There are various screening methods are used for early diagnosis of colorectal diseases. Among them fecal occult blood test is the most widely used screening test. Objectives: The objectives of the present study were to find out the role of immunological method of fecal occult blood test for screening colorectal diseases. Methods: This was a prospective study consisted of 110 patients suspected to have colorectal diseases of both sexes attending in Gastroenterology and Clinical Pathology department of Bangabandhu Sheikh Mujib Medical University. Stool samples of all the patients were examined by immunological method of fecal occult blood test and then advised for colonoscopy and histopathology for confirmatory diagnosis. The results of immunological method of fecal occult blood test and the colonoscopic findings were compared. Results. Of 110 patients, 87 (79%) cases were positive and 23 (20.9%)cases were negative by immunological method of fecal occult blood test. According to colonoscopy and histopathology, 65(32.5%) cases were found to have colorectal diseases and 45(22.5%) cases had no pathology. Diseases detected by colonoscopy in occult blood test positive patients, 18(16.4%) colorectal polyp, 24(21.8%) colonic ulcer, 8(7.3%) colorectal cancer, 5(3.5%) inflammatory bowel disease, 7(6.4%) haemorrhoids and fissure, 2(1.8%) colonic diverticulum and 1(0.9%) proctitis. Among the 65(32.5%) lesions detected by colonoscopy,62(95.3%) cases were positive by immunological method of fecal occult blood test where as only three(3) lesions were found in occult blood test negative cases. The sensitivity, specificity, PPV and NPV of immunological method of fecal occult blood test (IFOBT) for detection of occult bleeding were 95.4%, 44.4%, 71.3% and 87.0% respectively. Conclusion: It can apparently be concluded from this study that the role of immunological method of fecal occult blood test for colorectal diseases is promising in Bangladesh.

Role of Hematologic Scoring System in Early Diagnosis of Neonatal Septicemia

Background: Neonatal septicemia is one of the major health problems throughout the world. Infections are a frequent and important cause of morbidity and mortality in neonatal period. Objective: The objective of this study was the role of hematologic scoring system (HSS) in the early diagnosis of neonatal septicemia. Methods: This is a prospective study consisted of 100 neonates admitted at neonatal ICU, BSMMU, who were clinically suspected cases of septicemia. The neonatal hematological parameter was measured in all cases. Blood culture was done for the gold standard of proven sepsis. There were 12 out of 100 neonates (12%) who had culture proven sepsis. They were predominantly preterm and of very low birth weight. Results: On evaluation of various hematological parameters total leucocytes count, total neutrophil count, IT ratio (>0.2), IM ratio (> 0.3), total immature PMNs count, platelet count were found to have optimal sensitivities and negative predictive values. Using these values hematologic scoring system was formulated according to Rodwell et al. Score > 4 has a sensitivity of 100%, specificity of 60%, with PPV 26% and NPV 100 %. Considering the high sensitivity, negative predictive value, this study implies that score > 4 were more reliable as a screening tool for sepsis than any of the individual hematological parameter. Conclusion: HSS are useful test to distinguish the infected from non infected infants. They also provide a effective guideline to make decisions regarding judicious use of antibiotic therapy.Keywords: Hematologic scoring system (HSS); Blood culture; Neonatal septicemia DOI: 10.3329/bsmmuj.v3i2.7053BSMMU J 2010; 3(2): 62-6

Comparison of serum homocysteine level in young and middle-aged adult patients with coronary artery disease

Deaths due to coronary artery disease have been increasing in young people aged 15 mmol/L) was 16.2% in Group I compared to 12.4% in Group II (P=0.001). Therefore, control measures for keeping homocysteine levels within the normal range in young people might be useful. BSMMU J 2022; 15(3): 197-20

RDWI is Better Discriminant than RDW in Differentiation of Iron Deficiency Anaemia and Beta Thalassaemia Trait

Iron deûciency anemia (IDA) and beta-thalassemia trait (BTT) are the common causes of microcytic hypochromic anaemia. Several discrimination indices have been introduced to discriminate quickly these similar entities via parameters obtained from automated cell counter. The purpose of the study was to compare the value of two discrimination indices, red cell distribution width index (RDWI) and red cell distribution width (RDW) in differentiation of BTT and IDA. This study consists of 57 cases of BTT and 72 cases of IDA. Severe anaemia (<7.0 gm/dl) had been excluded because these cases are not confused with BTT cases in practice. Sensitivity, specificity, positive and negative predictive values and Youden’s index of both indices in differentiation of BTT and IDA had been calculated. RDWI appears to be reliable and useful index for differentiation of iron deficiency anaemia and beta thalassaemia trait. Again RDWI is better than RDW in differentiating BTT from IDA.

Comparison of serum homocysteine level in young and middle-aged adult patients with coronary artery disease: Homocysteine in coronary artery disease

Deaths due to coronary artery disease have been increasing in young people aged <40. Studies have reported an association between these deaths with hyperhomocysteinemia. The aim of this study was to compare serum homocysteine levels in middle-aged patients with coronary artery disease. This cross-sectional study was conducted among 52 cardiology inpatients of Bangabandhu Sheikh Mujib Medical University, Dhaka, from March 2021 to February 2022. Among them, 26 were young adults (<40 years, Group I), and 26 were middle-aged (≥40 years, Group II). Serum homocysteine was measured in all of them using an automated immunoassay analyzer. The younger patients had higher (P=0.001) median homocysteine (interquartile range) level, 13.5 (7.7 –28.4 mmol/L) compared to the middle-aged group, 10.0 (5.9 – 38.5 mmol/L). The hyperhomocysteinemia (>15 mmol/L) was 16.2% in Group I compared to 12.4% in Group II (P=0.001). Therefore, control measures for keeping homocysteine levels within the normal range in young people might be useful. BSMMU J 2022; 15(3): 197-20
