RESUMO
Background: VEGF play a significant role in the pathogenesis of chronic myeloid leukemia. Aims & Objective: (1) Assess the pathophysiological role of VEGF in patients with chronic myeloid leukemia (CML). (2) Study the effect of Hydroxyurea and Imatinib on serum VEGF level. Material and Methods: A total of 40 cases of chronic myeloid leukemia (CML) and 20 age and sex matched healthy controls were included in this study. The patients were divided into 3 subcategories: Untreated cases (which did not receive any treatment); patients who were treated with Hydroxyurea and patients who were treated with Imatinib Mesylate. 5 ml of blood was collected, were centrifuged at 5000 rpm for 10 minutes and stored at - 20°C until assay. Results: On comparing the various subgroups with control, the value was 726.61 ± 199.67 pg/ml in untreated group. It was 573.53 ± 213.423 pg/ml in Hydroxyurea group and 530.00±180.96 pg/ml in Imatinib group. Fresh cases had significantly elevated VEGF value (P value < 0.001). VEGF level significantly elevated in Untreated cases when compared to treated groups either hydroxyurea (p=0.02) or Imatinib (p=0.019). There was no significant difference between Hydroxyurea and Imatinib groups. Conclusion: This study suggests that VEGF play a significant role in the pathogenesis of chronic myeloid leukemia. Understanding this may help in designing new therapeutic strategies (antiangiogenic agents) for this dreaded disease.
RESUMO
Background: HIV, the disease, whose mode of transmission is known and is largely preventable, but due to lack of knowledge and practices about HIV/AIDS in general population causes its rapid spread. Aims & Objective: To assess and compare the knowledge, attitude and practices about HIV in patients group, care giver and in general population. Material and Methods: A total of 102 HIV/AIDS patients, 60 care givers (35 attendant, 19 nurses, 6 doctors) and 40 general population (control) were included in the present study. The patients who were registered for study were followed up for three visits. The responses were recorded on a pre-designed and pre-tested, semi- structured questionnaire. Results: Illiteracy was more common in HIV patient group (27.5%) . A high proportion of HIV/AIDS cases were engaged in transport/ production industry (24.5%). Electronic media and print media are major source of information. 35.3% patients, 22.9% care givers and 47.5% general population group thought that with medication HIV is curable. Sexual contact (63.8%) was the commonest mode of transmission. 80.0% medical staff thought that a newly diagnosed HIV person, first to talk with doctor. After 6 month follow up: 82% patients write sexual contact as major mode of transmission, and Use of condom was most important preventive measure (68%). Conclusion: Understanding the KAP about HIV/AIDS of Patients, care givers and in general populations will help us in formulating strategy for prevention and treatment.
