- TB and Glucose Metabolism: TB can lead to impaired glucose tolerance, which might normalize after treatment but increases the risk for T2DM due to stress, inflammation, and metabolic changes. See also: https://lintblab.weebly.com/group-members.html
- Hyperglycemia in TB: Hyperglycemia is common in TB patients (10-26% prevalence), resulting from systemic inflammation and altered metabolism.
- Immunometabolic Impact: TB causes significant changes like increased inflammation, altered adipose tissue function, and elevated free fatty acids, contributing to insulin resistance (IR).
- Lipid Dysregulation: TB infection increases free fatty acids, leading to high LDL, low HDL, high VLDL, and ectopic fat deposition in organs, promoting IR.
- TB-DM Co-occurrence: When TB and diabetes coexist, it complicates treatment, potentially leading to drug resistance and poorer outcomes.
- Impact on TB Treatment: Diabetes negatively affects TB treatment success, increasing mortality, failure rates, and loss to follow-up.
- Immune Deficiency in Diabetes: Diabetes compromises immune function, reducing TB control by impairing macrophage activity, cytokine release, and T-cell responses.
- Altered Immune Response in Latent TB: Diabetic patients with latent TB exhibit heightened inflammatory responses, suggesting altered immune signaling.
- Clinical Management: Integrated management of TB and DM/IR is necessary to prevent diabetes progression and improve TB outcomes.
- HbA1c Monitoring: Regular HbA1c monitoring during TB treatment helps identify individuals at risk for poor outcomes due to hyperglycemia.
- Diabetes Treatment: Effective diabetes management in TB patients leads to better clinical outcomes, reducing TB severity and complications.
- Symptom Severity: TB in diabetic patients often results in more severe symptoms, correlated with higher HbA1c levels.
- Cardiovascular Complications: TB increases the risk of cardiovascular diseases through metabolic and inflammatory pathways.
- CVD Risk Management: Screening for CVD risk factors and promoting lifestyle changes are crucial in TB patients to manage cardiovascular health.
- Interdisciplinary Approach: The management of TB alongside conditions like CVD and diabetes needs cross-specialty collaboration for optimal patient care.
