Topic 1: Multidrug-Resistant Disease: Tuberculosis
PART 2: BACKGROUND OF TOPIC Tuberculosis is a bacterial disease that is spread through the air from person to person. It attacks the lungs mainly, although it can also affect different areas in the body such as the kidneys, the brain, and the spine. Tuberculosis is both preventable and curable. It requires treatment and proper medication use. If someone affected by TB is not properly treated there is a high risk of death. The two main drugs used in curing patients with TB are isoniazid and rifampicin. Multidrug-Resistant Tuberculosis(MDR TB) is resistant to both of these drugs used for treatment, making it extremely hard to cure patients with the disease. Tuberculosis travels through the bloodstream and makes the immune system weak. Multidrug-Resistant TB is caused by improper use of medication. To prevent Tuberculosis from becoming Multidrug-Resistant, patients should take their full prescriptions of their antibiotics, make certain that their antibiotics are high quality, and perform the proper treatment course. Extensive Mulitdrug-Resistant Tuberculosis(XDR TB) is even more of a threat due to its resistance to more drugs than just isoniazid and rifampicin. Being resistant to a wide range of medication, Extensive Mulitdrug-Resistant Tuberculosis is even harder to cure than MDR TB. It leaves patients with small options of treatment that have little effect. People with autoimmune diseases like HIV are way
Tuberculosis has long been a disease that the human culture has been dealing with which entails significant morbidity and mortality worldwide. With dealing with such a horrific disease over the years, discoveries and evolution on the appropriate ways to contain, diagnose, and challengingly treat the disease has changed. One of the most concerning complications of this worldwide public health issue is the ability for it to quickly spread in high populated areas while becoming ever more resistant to forms of treatment not available in all locations around the world. This is a serious public
Tuberculosis is a disease of an infectious nature caused by a bacterium known as mycobacterium tuberculosis. The disease spreads through the air. People with the disease can spread it to susceptible people through coughing, sneezing, talking or spitting. It mainly affects the lungs and other parts such as the lymph nodes and kidneys can also be affected. The symptoms for TB are fatigue, coughing, night sweats, weight loss and fever. One third of the population of the world is affected with mycobacterium tuberculosis. The rate of infection is estimated to be one person per second. About 14 million people in the world are infected with active tuberculosis. Drug resistant TB has been recorded to be a serious public health hazard in many countries. Resistant strains have developed making it difficult to treat the disease. TB has caused millions of death mainly in people living with HIV/AIDS ADDIN EN.CITE Ginsberg19981447(Ginsberg, 1998)1447144717Ginsberg, Ann M.The Tuberculosis Epidemic: Scientific Challenges and OpportunitiesPublic Health Reports (1974-)Public Health Reports (1974-)128-13611321998Association of Schools of Public Health00333549http://www.jstor.org/stable/4598234( HYPERLINK l "_ENREF_3" o "Ginsberg, 1998 #1447" Ginsberg, 1998). The World Health Organization came up with the DOTS (Directly Observed, Therapy, Short course) strategy. The approach involves diagnosing cases and treating patients with drugs for about 6-8
Tuberculosis, the white plague as used to be called once upon a time is still one of the deadliest bacterial killers affecting almost all parts, all corners of the globe. Though successful anti-tubercular antibiotic regimens and effective vaccine are available for decades and being used in the battle against Koch’s bacillus, Mycobacterium tuberculosis, the causative agent of this chronic multi organ granulomatous disease, our strand in the battle continuously seems to be in the losing side. Moreover the increasing prevalence of HIV-AIDS and diabetes mellitus is being proved to be providing predisposition to tuberculosis. As witnessed by the WHO, which has estimated that, in the year 2012, 8.6 million people have developed tuberculosis and 1.3 million have died of the disease including 320000 deaths of HIV-TB co-infected people (Global tuberculosis report 2013. World Health Organization; 2013). Long term antibiotic therapy and that too associated with several side effects and discomforts have diminished patient compliance with the anti-tubercular chemotherapy. This fact in turn has raised the new deadlier MDR-TB and XDR-TB strains. The whole scenario is a matter of panic and questioning the effectiveness of anti-tubercular antibiotics, immunologic efficacy of century old BCG vaccine and all other medical advents.
Tuberculosis is caused by the bacteria “Mycobacterium Tuberculosis” and is mainly causes infection of the lungs (WHO, 2016). Its mode of transmission is airborne, so it can be passed on by inhalation of airborne droplets which carrying the bacteria, when an infected patient coughs, sneezes, or spits the TB germs into the air (WHO, 1026). Among the symptoms of active TB are: cough with sputum and blood, chest pains, weakness, fever and night sweats (WHO, 2016). Most at risk to get the TB infection are people with weakened immune system such as people who are suffering from chronic diseases such as diabetes mellitus, severe kidney disease, silicosis and especially HIV infection (CDC, 2016). Children and Tobacco users are also at greater risk to fall ill with TB.
Due to the transmission that TB is spread, through the air from one person to another coughing, sneezing, and speaking. It is vital that those who have TB disease are treated, complete the medicine regimen, and take the medications exactly as prescribed. If one was to discontinue the medications without completion, they can become ill again and if they do not take the drugs correctly, the TB bacteria that are still alive may become resistant to those medications. TB must be treated by taking antibiotics, the exact drugs and length of treatment depend on your age, overall health, possible drug resistance, the form of TB, latent or active, and the location
According to the World Health Organization, tuberculosis (TB) is the number two killer worldwide due to a single infectious agent (WHO, 2017). In 2015, 10.4 million new cases have been identified and 1.8 million people have died from this disease (WHO, 2017). TB is caused by the bacteria Mycobacterium TB, and the majority of TB deaths occur in low and middle-income countries. This disease is curable and preventable, but the lack of access to proper healthcare and medication administration makes it a concern for the most of the world’s population. TB is an airborne disease that can transmit when an infected person coughs, sneezes, spits, laughs, or talks. The majority of TB cases can be cured when the right medications are available and
Tuberculosis is one of the major causes of death from many infectious diseases (3). Out of 9 million people who are infected with mycobacteria, about 2 million deaths occur from tuberculosis every year (3). Unfortunately, the prevalence of tuberculosis is in a continuous increase due to increased number of Human immunodeificnecy virus (HIV) patients, bacterial resistance to anti-tuberculous drugs, and growing number of recreational drug users (3). The pathogen responsible for bacterial infection, potentially causing tuberculosis, is mycobacterium tuberculosis (MTB) (2). Persons with adequate immune system can control the bacterial infection so mycobacteria remain dormant for a long time (11). In a typical tuberculous granuloma, mature
One of the biggest growing problems in our health care system is hospital acquired infections. Some of the common infections are known as "super bugs' or multidrug-resistant organisms such as Clostridium difficile (C.diff) and methicillin-resistant Staphylococcus aureus (MRSA). Multidrug-resistant organisms means that the pathogens can resist the effects of drugs, are not killed and their growth is not stopped which can ultimately threaten a patient's safety. This is why hospitals are looking into other methods to help ensure more effective environmental cleaning and disinfection. That is where pulsed UV light disinfection systems are coming into play.
A person with fully susceptible TB may develop secondary (acquired) resistance during therapy because of inadequate treatment, not taking the prescribed regimen appropriately, or using medication of low quality. Drug-resistant tuberculosis is a serious public health issue in many developing countries because its treatment is lengthy and more expensive drugs are necessary. MDR-TB is defined as resistance to the two most effective first-line Tuberculosis drugs: rifampicin and isoniazid. Extensively drug-resistant tuberculosis is also resistant to three or more of the six classes of second-line
Tuberculosis (TB) is a chronic bacterial infection that affects millions of people globally. It is a contagious disease that is spread through the air, and it usually affects the lungs. It is transmitted from person to person through droplets from the respiratory tract of those who are already infected with the disease. Some who are infected with the bacteria that causes TB often exhibit no symptoms, because their immune systems stop the bacteria from growing and multiplying. Those with compromised immune systems are more susceptible to developing the full blown disease which can cause symptoms that include coughing, spitting blood, chest pains, weakness, weight loss, and fever. Tuberculosis can be treated with a six to nine month course of a combination of antibiotics. If left untreated, TB will spread and can be fatal.
TB is caused by a bacterial infection known as mycobacterium tuberculosis. If a patient is sick with TB is considered a disease. The infection is prevalent in the HIV population because approximately 13 million Americans are effected by the TB bacteria. It typically involves the lungs but can also affect the brain and other organ systems. The TB germ is airborne and can live in the air for several hours. Once an affected person coughs or sneezes another person breathes in the germ and becomes infected. A patient with TB and HIV/AIDS will have to take an antibiotics long term to battle the infection. They will have to go through two phases of medication. The initial phase consists of utilizing drugs such as isoniazid, pyrazinamide, rifamycin, and ethambutol for the first couple of months. Then the patient will enter into the continuation phase, during this phase the patient will take the isoniazid and rifamycin for approximately four months. HIV patient’s that are taking antiretroviral for the HIV will have to take the antibiotics longer. A person taking treatment for TB has to be careful because the antibiotic can cause liver damage. According to the CDC, roughly 6% of all TB cases are from patients with HIV or AIDS. In 1992 the United States had a dramatic increase in TB cases but has decreased ever since. Recently a group of researchers at John Hopkins
Drug resistance has been increasing among patients infected with Mycobacterium tuberculosis. Previous miracle drugs that were used in the 1950s have now been proven useless in many cases simply because the bacteria are not susceptible to antibiotics such as isoniazid, rifampin, pyrazinamide, etc. when they are taken. This pathogen is easily transmitted through air and has the capability of attacking the respiratory system and creating fatal consequences if not treated properly. A lot of people who contribute to the antibiotic resistant statistics are those that do not take medication accordingly. Even though the bacterium may not be resistant at first, it can
For years now drug resistance is increasing and not just in one or two strands of bacteria, it is in all of them. This resistance makes treating a patient with the infection more difficult to the point where some strands require surgery. Tuberculosis is not a bacterium that you can easily remove from the body though. It takes time and medication for the tuberculosis to be eradicated from the body. The problem is with the advancements of medicine bacterium, like tuberculosis, are starting to produce resistance to not just one or two drugs here or there, but the bacteria is producing resistance for multiple drugs at one time.
Tuberculosis is among the fatal diseases that are spread through the air. It’s contagious, meaning that it spreads from one infected individual to another, and at times it spreads very fast. In addition to being contagious, the disease is an opportunist infection as it takes advantage of those with weak defense mechanism, and especially the ones with terminal diseases like HIV and AIDS. Tuberculosis is therefore among the major concerns for the World Health Organization due to its contagious nature (World Health Organization 1).
In 2011, WHO estimated 12 million prevalent cases of tuberculosis worldwide, of which about 630 000 (roughly 5%) were MDR tuberculosis. The highest caseloads of MDR tuberculosis were reported in India, China, Russia, and South Africa, which accounted for more than 60% of cases worldwide. India and China have the highest number of MDR tuberculosis cases worldwide. Tuberculosis has now been made a notifiable disease in India. Drug resistance surveys in several states have indicated that the prevalence of MDR TB in India is 2–3 percent among new cases and 12-17 percent among reinfection cases. According to drug
