ABSTRACT
Objectives: To compare the serum vitamin D and serum cathelicidin antimicrobial peptide (CAMP) levels among tuberculosis patients and healthy subjects and to determine the association between serum vitamin D and cathelicidin in tuberculosis. Materials and Methods: This is a case-control study carried out at the pulmonary medicine and pediatrics departments of a tertiary care hospital in Chengalpattu. The study included 180 tuberculosis cases and 90 control subjects of both sexes between the age group of 1 to 80 years. Serum was used to estimate vitamin D and CAMP. The study was analyzed using SPSS version 21 (IBM Corp. Armonk, New York). The results were evaluated using the chi-square test at a 95% confidence interval, and P value <.05 was considered highly significant. Results: This study observed vitamin D deficiency, vitamin D insufficiency, and optimum vitamin D among 55%, 41%, and 3.89% tuberculosis cases, respectively. Similarly, vitamin D deficiency, vitamin D insufficiency, and optimum vitamin D were seen in 40%, 50%, and 10% healthy controls, respectively. Conclusion: This study found no association between serum vitamin D and serum CAMP levels in tuberculosis patients and healthy controls.
ABSTRACT
Background: The Electrocardiogram remains a crucial tool in the identification and management of acute myocardial infarction. A detailed analysis of patterns of ST segment elevation may influence decisions regarding the perfusion therapy. This study was undertaken to study the role of ECG in identifying the infarct related artery in acute ST elevation MI and to correlate its findings with 2 D ECHO and Coronary angiogram.Methods: A total of 100 patients who presented with acute ST elevation MI were randomly selected for the study. After admission all the patients underwent ECG, CPK, CK-MB levels, 2D ECHO and CAG. Patients with ST segment elevation from ECG was evaluated to identify culprit vessel and the ECG findings were then correlated with 2D ECHO and CAG to identify the Sensitivity, Specificity, Positive predictive value and Negative predictive value of ECG in identifying the infarct related artery.Results: Fifty-two (52%) patients had an Anterior wall MI, forty-two patients (42%) had an evidence of Inferior wall MI and Six patients (6%) were found to have Antero inferior wall MI in the study group. Thirty-eight (38%) had evidence of SVD, forty-six patients (46%) had DVD and Sixteen patients (16%) had TVD. Sensitivity, Specificity, PPV and NPV of the ECG in identifying the LAD artery occlusion were 60.5%, 100%, 100% and 44.4% respectively. Sensitivity, Specificity, PPV and NPV of ECG in identifying the RCA artery occlusion were 78.5%, 100%, 100% and 78.5% respectively. Sensitivity, Specificity, PPV and NPV of the ECG in identifying the LCx artery occlusion were 26%, 96%, 86% and 60% respectively.Conclusions: ECG was found to be a sensitive and specific tool in identifying the infarct related Coronary artery in acute ST elevation MI.
