Association between cardiometabolic risk factors and multidrug-resistant tuberculosis: A case-control study

by Sishir Poudel, Laxman Wagle, Tara Prasad Aryal, Binay Adhikari, Sushan Pokharel, Dipendra Adhikari, Kshitiz Bhandari, Kshitiz Rijal, Jyoti Bastola Paudel

Background

Multidrug-resistant tuberculosis (MDR-TB) continues to be a major public health concern, especially in high-burden countries like Nepal. While individual risk factors are known, the cumulative impact of cardiometabolic factors on MDR-TB is not well understood.

Methods

A health-facility-based, age- and sex-matched 1:2 case-control study was conducted at MDR-TB treatment centers in Gandaki Province, Nepal. MDR-TB patients (cases) and drug-sensitive tuberculosis (DS-TB) patients (controls) were enrolled. Cases were defined as adults (≥18 years) with confirmed MDR-TB; controls were adults with sputum-positive DS-TB. Data on sociodemographics, cardiometabolic risk factors (alcohol, tobacco, abnormal body mass index, hypertension, diabetes), TB literacy, and treatment history were collected using a structured, pretested questionnaire by trained medical officers. Data were analyzed using Stata v13.0. Binary logistic regression was used to assess associations between risk factors and MDR-TB. Ethical approval was obtained from the Nepal Health Research Council and written informed consent was obtained from all participants.

Results

A total of 183 participants (61 cases, 122 controls) were included. Mean age of participants was 42.5 years (SD = 18.5); 73.8% were male. Most participants were from urban areas (74.9%), and 66.7% were unemployed. Cardiometabolic risk factors were present in 79.2% of participants. Alcohol and tobacco use were reported by 59.6% and 45.9%, respectively; 9.8% had diabetes and 7.1% had hypertension. Known TB contact and prior TB history were reported by 26.8% and 31.1% respectively. In multivariate analysis, unemployment (AOR: 5.24, 95% CI: 1.33–20.64), and known TB contact (AOR: 8.89, 95% CI: 2.46–32.15) were significantly associated with MDR-TB. Cardiometabolic risk factors were not significantly associated.

Conclusion

Known TB contact and unemployment were significantly associated with MDR-TB, while the cumulative effect of cardiometabolic risk factors showed no significant impact, indicating that interventions should prioritize established TB-related risk factors.

Objective

To assess factors associated with the adoption of the WHO Package of Essential Non-Communicable Diseases (PEN) Protocol 1 at primary healthcare (PHC) facilities in Nepal after healthcare workers received training.

Design

Cross-sectional study.

Setting

PHC facilities across various provinces in Nepal.

Participants

A total of 180 healthcare workers trained in PEN, recruited from a random selection of 105 basic healthcare facilities.

Main outcome measures

The adoption of PEN Protocol 1 components: blood pressure measurement, blood glucose screening, 10-year cardiovascular disease (CVD) risk assessment using WHO/International Society of Hypertension risk charts and body mass index (BMI) assessment. Factors associated with protocol adoption were assessed using generalised estimating equations for ORs.

Results

Among participants, 100% reported measuring blood pressure, while 56% measured blood sugar, 28% assessed CVD risk and 27% assessed BMI. The adoption of the CVD risk prediction chart was positively associated with the availability of amlodipine (adjusted OR (aOR) 3.00; 95% CI 1.09 to 8.27). The adoption of BMI assessment was positively associated with access to a stadiometer (aOR 3.23; 95% CI 1.26 to 8.30) and a glucometer (aOR 3.07; 95% CI 1.12 to 8.40), and negatively associated with lack of motivation/inertia of previous practice (aOR 0.60; 95% CI 0.42 to 0.87) and environmental factors such as lack of time and resources (aOR 0.57; 95% CI 0.37 to 0.89). Blood glucose level measurements were positively associated with being at a PHC centre (aOR 7.34; 95% CI 2.79 to 19.3) and the availability of metformin (OR 2.40; 95% CI 1.08 to 5.29).

Conclusion

Adoption of PEN Protocol 1 varied by component and was influenced by resource availability, provider motivation and system barriers. Addressing these factors is key to optimising implementation in low-resource settings.

Cohort profile: AMBulatoRy blOod preSsure in older adults (AMBROSIA) and AMBROSIA-HOME

Purpose

The AMBulatoRy blOod preSsure In older Adults (AMBROSIA) study cohort was designed to determine whether ambulatory blood pressure (BP) monitoring (ABPM) is useful for identifying older adults with hypertension taking antihypertensive medication who are at increased risk for falls. The association of home BP monitoring (HBPM) with falls was assessed in an ancillary study (AMBROSIA-HOME).

Participants

AMBROSIA was a prospective observational study of adults aged 65 years and older taking antihypertensive medication for hypertension. Participants were recruited from Kaiser Permanente Southern California (KPSC), an integrated healthcare delivery system, and enrolled from May 2019 to November 2022. Demographic and clinical characteristics and geriatric assessments were collected over the course of two consecutive study visits. Participants completed a 24-hour ABPM and 1 week of HBPM. Over the following year, falls were assessed using a monthly falls calendar, and serious fall injuries were assessed from the KPSC electronic health record (EHR).

Findings to date

We enrolled 670 participants; 656 completed 24-hour ABPM and 536 also completed HBPM. The mean (SD) age of the AMBROSIA cohort was 75 (6) years, 16% were over 80 years of age and 56% were female. There were 13% non-Hispanic Asian or Pacific Islander, 22% non-Hispanic Black, 18% Hispanic and 44% non-Hispanic White participants. Nearly 72% had mild cognitive impairment, 50% were pre-frail and 4% were frail. Overall, 87% of participants returned all monthly calendars during follow-up.

Future plans

The AMBROSIA cohort can be updated with longitudinal data from the EHR including antihypertensive medication to explore the relationship of fall risk and white coat effect, defined as the difference between clinic BP and out-of-clinic BP, BP variability over 24 hours and postprandial BP decline with antihypertensive medication intensification during follow-up. Additionally, the cohort can be updated to include outcomes data from the EHR such as cardiovascular events to examine BP phenotypes as potential predictors of cardiovascular events.

Introduction

Recessive dystrophic epidermolysis bullosa (RDEB) is a severe genetic mucocutaneous fragility disorder characterised by chronic blistering, slow wound healing and increased risk of squamous cell carcinoma. Current management options are very limited.

Methods

This is a randomised (1:1), placebo-controlled, double-blinded crossover (A/B) trial with an internal phase I dose de-escalation (4+5 design) in the first 3 months and a 12-month continued treatment follow-on open-label study if 3-month outcome data from the crossover trial indicate safe and beneficial effects. RDEB is a rare condition, so we expect to recruit a maximum of 36 participants based on feasibility and not formal power considerations. Participants aged>6 months and x106 cells/kg intravenous infusion of umbilical cord-derived mesenchymal stem cells or placebo at the start of each crossover period (day 0) and 14 days later. The dose will be de-escalated to 1–1.5x106 cells/kg depending on observed toxicity. For the main crossover trial, the primary outcome is the change in disease severity as measured by the Epidermolysis Bullosa Disease Activity and Scarring Index at 3 months from day 0 infusion. Secondary outcomes measured at 3 and 6 months from day 0 infusion include changes in general clinical appearance of skin disease, pain and itch, and quality of life. Adverse events and serious adverse events will be monitored throughout the trial.

Ethics and dissemination

North East—York Research Ethics Committee approved the protocol (ref: 21/NE/0016) on 16 March 2021. Findings will be published in peer-reviewed scientific journals, presented at relevant national and international conferences, and an open-access final report submitted to the funder.
