Higher plasma interleukin - 6 levels are associated with lung cavitation in drug-resistant tuberculosis.

ABSTRACT:

Background

Lung cavitation is associated with heightened TB transmission and poor treatment outcomes. This study aimed to determine the relationship between systemic inflammation and lung cavitation in drug-resistant TB patients with and without HIV co-infection.

Methods

Plasma samples were obtained from 128 participants from the CAPRISA 020 Individualized M(X)drug-resistant TB Treatment Strategy Study (InDEX) prior to treatment initiation. Lung cavitation was present in 61 of the 128 drug-resistant TB patients with 93 being co-infected with HIV. The plasma cytokine and chemokine levels were measured using the 27-Plex Human Cytokine immunoassay. Modified Poisson regression models were used to determine the association between plasma cytokine/chemokine expression and lung cavitation in individuals with drug-resistant TB.

Results

Higher Interleukin-6 plasma levels (adjusted risk ratio [aRR] 1.405, 95% confidence interval [CI] 1.079-1.829, p = 0.011) were associated with a higher risk of lung cavitation in the multivariable model adjusting for age, sex, body mass index, HIV status, smoking and previous history of TB. Smoking was associated with an increased risk of lung cavitation (aRR 1.784, 95% CI 1.167-2.729, p = 0.008). An HIV positive status and a higher body mass index, were associated with reduced risk of lung cavitation (aRR 0.537, 95% CI 0.371-0.775, p = 0.001 and aRR 0.927, 95% CI 0.874-0.983, p = 0.012 respectively).

Conclusion

High plasma interleukin-6 levels are associated with an increased risk of cavitary TB highlighting the role of interleukin-6 in the immunopathology of drug-resistant TB.

Project description:Drug-resistant epilepsy is the most severe form of epilepsy and is frequently associated with cognitive decline. Whether drug-resistant epilepsy results in neurodegeneration or other types of brain injury is not known, and early detection of detrimental clinical trajectories would be clinically very useful. Blood biomarkers of brain injury reflect neurodegeneration or brain injury in several brain diseases but have not been extensively studied in epilepsy. We investigated a panel of such markers in a large epilepsy cohort with an emphasis on assessing differences between drug-resistant and monotherapy-controlled epilepsy. Blood neurofilament light, glial fibrillary acidic protein, total tau, S100 calcium-binding protein B and neuron-specific enolase concentrations were measured in 444 patients (aged ≥ 18 years) with epilepsy participating in a prospective regional Biobank study in Västra Götaland (Sweden). Multiple linear regression assessed associations between clinical variables and marker levels. Levels were then compared between patients with drug-resistant epilepsy (n = 101) and patients with monotherapy-controlled epilepsy (n = 164). We also performed logistic regression analysis to evaluate the significance of the markers as predictors of epilepsy status (drug-resistant epilepsy or monotherapy-controlled epilepsy) while controlling for clinical variables: age, sex, epilepsy duration, epilepsy type and lesions. All markers correlated with age. In younger patients (≤50 years), cases of drug-resistant epilepsy had higher levels of neurofilament light (P = 0.002) and glial fibrillary acidic protein (P = 0.006) compared with monotherapy-controlled epilepsy. After excluding patients with known structural lesions, neurofilament light levels remained significantly elevated in drug-resistant epilepsy versus monotherapy-controlled epilepsy (P = 0.029). Neurofilament light also emerged as a significant predictor of drug-resistant status in a logistic regression model following adjustments for clinical variables. Future studies should explore if neurofilament light can be used for surveillance of disease course and whether it reflects brain injury in drug-resistant epilepsy.

Project description:Tuberculosis stands as a prominent cause of mortality in developing countries. The treatment of tuberculosis involves a complex procedure requiring the administration of a panel of at least four antimicrobial drugs for the duration of six months. The occurrence of treatment failure after the completion of a standard treatment course presents a serious medical problem. The purpose of this study was to evaluate antimicrobial drug resistant features of Mycobacterium tuberculosis associated with treatment failure. Additionally, it aimed to evaluate the effectiveness of second line drugs such as amikacin, linezolid, moxifloxacin, and the efflux pump inhibitor verapamil against M. tuberculosis isolates associated with treatment failure. We monitored 1200 tuberculosis patients who visited TB centres in Lahore and found that 64 of them were not cured after six months of treatment. Among the M. tuberculosis isolates recovered from the sputum of these 64 patients, 46 (71.9%) isolates were simultaneously resistant to rifampicin and isoniazid (MDR), and 30 (46.9%) isolates were resistant to pyrazinamide, Resistance to amikacin was detected in 17 (26,5%) isolates whereas resistance to moxifloxacin and linezolid was detected in 1 (1.5%) and 2 (3.1%) isolates respectively. Among MDR isolates, the additional resistance to pyrazinamide, amikacin, and linezolid was detected in 15(23.4%), 4(2.6%) and 1(1.56%) isolates respectively. One isolate simultaneously resistant to rifampicin, isoniazid, amikacin, pyrazinamide, and linezolid was also identified. In our investigations, the most frequently mutated amino acid in the treatment failure group was Serine 315 in katG. Three novel mutations were detected at codons 99, 149 and 154 in pncA which were associated with pyrazinamide resistance. The effect of verapamil on the minimum inhibitory concentration of isoniazid and rifampicin was observed in drug susceptible isolates but not in drug resistant isolates. Rifampicin and isoniazid enhanced the transcription of the efflux pump gene rv1258 in drug susceptible isolates collected from the treatment failure patients. Our findings emphasize a high prevalence of MDR isolates linked primarily to drug exposure. Moreover, the use of amikacin as a second line drug may not be the most suitable choice in such cases.
