Leptin and advanced glycation end products receptor (RAGE) in tuberculosis patients.

Introduction: The pathogenesis of consumptive syndrome of tuberculosis (TB) is largely unknown. Leptin concentrations may be high because of the host's inflammatory response, contributing to weight loss in patients with TB. The receptor for advanced glycation end products (RAGE) is also associated with weight loss in patients with TB and is related to enhanced mortality.

Advanced glycation end products (AGE) and receptor for AGE (RAGE) in patients with active tuberculosis, and their relationship between food intake and nutritional status.

Introduction: The receptor for advanced glycation end products (RAGE) is expressed in normal lungs and is upregulated during infection. AGEs and RAGE cause oxidative stress and apoptosis in lung cells. The objective of this study is to evaluate levels of AGEs and its soluble receptor (sRAGE), and to investigate their relationship with food intake and nutritional status, in a university-affiliated hospital in Brazil.

The relation between leptin and inflammatory markers with respiratory and peripheral muscle strength in tuberculosis: A case-control study.

Background: Muscle weakness is a part of the wasting syndrome associated with TB. Cytokines are candidates as the initial causative agents of the metabolic changes in TB. The objective of this study is to assess the peripheral and respiratory muscle strength in patients with TB and controls and relate these findings with leptin, IL-6 and TNF-α serum levels.

Nutrition Status Among HIV-Positive and HIV-Negative Inpatients with Pulmonary Tuberculosis.

Background: The association between tuberculosis (TB) and malnutrition is well recognized. Considering the risk of mortality due to malnutrition in patients with TB, it is necessary to conduct a thorough nutrition assessment to identify individuals at nutrition risk. The study objective was to assess the nutrition status of hospitalized patients with TB, co-infected or not by human immunodeficiency virus (HIV).

Health-Related Quality of Life, Depression and Anxiety in Hospitalized Patients with Tuberculosis.

Background: Much of the attention of tuberculosis (TB) programs is focused on outcomes of microbiological cure and mortality, and health related quality of life (HRQL) is undervalued. Also, TB patients have a significantly higher risk of developing depression and anxiety compared with those in the general population. We intend to evaluate the HRQL and the prevalence of symptoms of depression and anxiety in hospitalized patients with TB.
