In-depth: New resistance tests set to improve TB treatment (post)
Some strains of the TB bacterium have mutated to become resistant to some of the drugs commonly used to treat TB. Accordingly, one of the first questions to ask when someone has TB is which drugs will be effective in fighting that person’s TB. Unfortunately, quick answers to this question are not always available. As a consequence, people are at times treated with drugs that won’t work for their particular strain of TB. What’s worse, these drugs often have significant side effects.
Mini bio-devices could help TB patients stick to their treatments (post)
Imagine the scenario: you’ve been told you have a disease that will kill you. But, the doctor adds, your life can be saved if you diligently take your medication. Don’t skip a day, don’t skip a dosage. Soon, however, you discover that the medication has a slew of side effects, including a loss of appetite, fatigue, and nausea. So you do stop.
Testing stool can help detect TB in kids (post)
Most TB testing today relies on sputum samples coughed up from the lungs. This makes intuitive sense since pulmonary (or lung) TB is the most common form of TB and sputum provides testable samples straight from the scene of infection.
Experts call for better screening and treatment of TB during pregnancy (post)
Busisiwe Beko, from Khayelitsha in the Western Cape, was diagnosed with drug-resistant tuberculosis (DR-TB) while she was pregnant. She remembers it as a very difficult period in her life.
LumiraDx announces new investment for ongoing development of its point of care molecular TB test (post)
Company receives $14.2M in grants from the Bill & Melinda Gates Foundation to support the TB test’s ongoing development and future launch into developing countries.
Lakhs of TB-infected children will benefit from a lollipop and chewing gum-inspired child-friendly sample collection device under development (post)
-- Nearly 1 – 1.15 lakh children in India get affected by TB every year. Thousands of cases go unmissed as the testing is not child friendly. Current sample collection methods are painful, time consuming and inconvenient.
-- First-of-its-kind sample collection device to be developed by 221B Biomedical Pvt. Ltd. with grant and support from India Health Fund, a Tata Trusts initiative.
-- The flavoured low-cost device will require children to simply chew and blow or cough for easy and safe sample collection of oral fluids.
-- The innovation will make testing simpler and will likely increase testing and treatment rates, lower mortality and infection transmission due to TB.
