What is the treatment for drug-resistant tuberculosis?
Treatment for Drug-Resistant TB. Extensively drug-resistant TB (XDR TB) is a rare type of MDR TB that is resistant to isoniazid and rifampin, plus any fluoroquinolone and at least one of three injectable second-line drugs (i.e., amikacin, kanamycin, or capreomycin). Treating and curing drug-resistant TB is complicated.

How did they treat tuberculosis in the 40s?
Rifampin combined with isoniazid and ethambutol enabled therapy to be shortened to 9 months and led to improved cure rates (35). Pyrazinamide was discovered in the late 1940s, based on the observation that nicotinamide had activity against M. tuberculosis in animal models.
How was TB treated in the 1920s?
In the 1920s and 1930s, following trends in Germany and America, collapse therapy was a popular method of treating pulmonary tuberculosis in Britain. The intention was to collapse the infected lung, allowing it to rest and heal.

What did Robert Koch discover about TB?
On March 24, 1882, Robert Koch announced his discovery that TB was caused by a bacteria in his presentation “Die Aetiologie der Tuberculose” at the Berlin Physiological Society conference. The discovery of the bacteria proved that TB was an infectious disease, not hereditary. In 1905, Koch won the Nobel Prize for Medicine and Physiology.

It is very important that people who have TB disease are treated, finish the medicine, and take the drugs exactly as prescribed. If they stop taking the drugs too soon, they can become sick again; if they do not take the drugs correctly, the TB bacteria that are still alive may become resistant to those drugs.

When was rifamycin first used?
The rifamycins were discovered in 1957 in Italy when a soil sample from a pine forest on the French Riviera was brought for analysis to the Lepetit Pharmaceuticals research laboratory in Milan, Italy. A research group led by Professor Piero Sensi and Dr Maria Teresa Timbal then discovered a new bacterium. This new species was of considerable scientific interest as it was producing a new class of molecules with antibiotic activity. Rifampin was first used clinically in 1966.
When was streptomycin first isolated?
The first public announcement of the isolation of the antibiotic was made in a paper in January 1944 6Schatz, A., Bugie, E., and Waksman, S. A. “Streptomycin, a Substance Exhibiting Antibiotic Activity against Gram-Positive and Gram-Negative Bacteria”, Proc. Soc. Exper. Biol.

Various preliminary studies of the production of antibiotics by actinomycetes resulted in the isolation of actinomycin in 1940 but it was extremely toxic. 5Waksman, S, “The Conquest of Tuberculosis”, Robert Hale Ltd, 1964 This was followed two years later by streptothricin which was also found to have significant toxicity.
Who was the first person to discover streptomycin?
9Pringle, Peter, “Experiment Eleven”, Bloomsbury Publishing, 2012 He also described Albert Schatz as “one of his assistants”. Albert Schatz was one of the graduate students who had worked with Waksman. Although he only worked with Waksman for a relatively short time, he had performed most of the laboratory experiments leading to the isolation of streptomycin. He was also the first author on the original publication and his name was on the patent application as one of the inventors.

How does spectinomycin work?
Spectinomycin works by binding to bacteria’s ribosomes, which are a crucial part of the cell’s protein-making machinery. The researchers analyzed the drug’s structure and made various chemical modifications to create a new class of agents known as spectinamides.
Do spectinamides work against TB?
The compounds have a high affinity for ribosomes in TB-causing bacteria, but not for those in mammalian cells. They also avoid being pumped out of the bacteria, thus making them more potent. The researchers demonstrated that the spectinamides were active against both MDR and XDR Mtb.

Why is TB called the "Captain of All These Men of Death"?
One hundred years later, TB was defined as "Captain of All These Men of Death" because of its epidemic proportions in Europe and North America, determining one in four deaths.

How long does it take to cure tuberculosis?
Tuberculosis, caused by Mycobacterium tuberculosis, is the most deadly infectious disease in the world. Standard TB therapy takes at least six months and patients infected with multi-drug resistant (MDR) or extensively drug resistant (XDR) strains undergo treatments that are even longer (up to 24 months).
How much does it cost to develop a new drug for TB?
Treatment is often associated with severe side effects. Studies indicate that the cost of developing a new drug has soared to $2.6 billion. The in vitro study indicates cephalosporins work well on their own against bacteria that cause TB.
How long does it take to treat tuberculosis?
If multiple drug-resistant TB (MDR-TB) is detected, treatment with at least four effective antibiotics for 18 to 24 months is recommended.
When did tuberculosis become epidemic in Europe?
In Europe, rates of tuberculosis began to rise in the early 1600s to a peak level in the 1800s, when it caused nearly 25% of all deaths. In the 18th and 19th century, tuberculosis had become epidemic in Europe, showing a seasonal pattern. By the 1950s mortality in Europe had decreased about 90%.
What is extrapulmonary TB?
In 15–20% of active cases, the infection spreads outside the lungs, causing other kinds of TB. These are collectively denoted as "extrapulmonary tuberculosis". Extrapulmonary TB occurs more commonly in people with a weakened immune system and young children. In those with HIV, this occurs in more than 50% of cases. Notable extrapulmonary infection sites include the pleura (in tuberculous pleurisy), the central nervous system (in tuberculous meningitis ), the lymphatic system (in scrofula of the neck), the genitourinary system (in urogenital tuberculosis ), and the bones and joints (in Pott disease of the spine), among others. A potentially more serious, widespread form of TB is called "disseminated tuberculosis", it is also known as miliary tuberculosis. Miliary TB currently makes up about 10% of extrapulmonary cases.
How does direct observed therapy work?
Directly observed therapy, i.e., having a health care provider watch the person take their medications, is recommended by the World Health Organization (WHO) in an effort to reduce the number of people not appropriately taking antibiotics. The evidence to support this practice over people simply taking their medications independently is of poor quality. There is no strong evidence indicating that directly observed therapy improves the number of people who were cured or the number of people who complete their medicine. Moderate quality evidence suggests that there is also no difference if people are observed at home versus at a clinic, or by a family member versus a health care worker. Methods to remind people of the importance of treatment and appointments may result in a small but important improvement. There is also not enough evidence to support intermittent rifampicin-containing therapy given two to three times a week has equal effectiveness as daily dose regimen on improving cure rates and reducing relapsing rates. There is also not enough evidence on effectiveness of giving intermittent twice or thrice weekly short course regimen compared to daily dosing regimen in treating children with tuberculosis.
What are the symptoms of active TB?
Typical symptoms of active TB are a chronic cough with blood-containing mucus, fever, night sweats, and weight loss.
How did public health affect the 1800s?
Public health campaigns which have focused on overcrowding, public spitting and regular sanitation (including hand washing) during the 1800s helped to either interrupt or slow spread which when combined with contact tracing, isolation and treatment helped to dramatically curb the transmission of both tuberculosis and other airborne diseases which led to the elimination of tuberculosis as a major public health issue in most developed economies. Other risk factors which worsened TB spread such as malnutrition were also ameliorated, but since the emergence of HIV a new population of immunocompromised individuals was available for TB to infect.
What is TB in the body?
Depiction of a man with tuberculosis . Tuberculosis ( TB) is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. Tuberculosis generally affects the lungs, but can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis.
