This is not only because of its daunting morbidity and mortality rates, both globally and in Europe (summarised in figs 1 and 2)[1, 3–5], but also because of the natural history of the disease. Active (contagious) tuberculosis disease occurs after a period of latency (or subclinical infection), and different risk factors [6–13], in combination with latent infection, introduce challenges to prevention, diagnosis and treatment of the disease. Vaccination against tuberculosis, if effective, would be therefore critical to control and elimination strategies [14–16].

  • *TREATMENT of Lepro.SY with DIASONE-A PRELIMINARY REPORT
    SUNGEI BULOH LEPER HOSPITAL 17 lepers. They certainly threatened to do so with a regularity that never became monotonous. Indeed I canot recall a week during which they did not threaten to bomb-out or machine gun the whole settlement, The reason why the Japanese confined them­ selves to threats is simply told. The leper settlement contained patients from all over .the Federated Malay States. Under the British regime these various states paid so much per head per day for their lepers maintained at Sungei Buloh. This payment was continued under th.e occupation for the Japanese, terrified of infectious disease, would rather levy money than risk the return of lepers to their various districts. Except for a token payment for the maintenance ot Sungei Buloh this money was retained by the local Japanese Governor for his own use. It will be realised that if he retained one shilling per head per day (which is about correct) for a thousand patients, he was making' a profit of fifteen hundred pounds per month. And so the lepers were spared-they were profitable. When the end came the hospital wards were empty, for no-one was left able to care for the sick. Like wraiths over the untended paths, the patients came out of their houses with un­ certain eyes and waivering gait, to welcome their liberators. *TREATMENT OF LEPRo.SY WITH DIASONE-A PRELIMINARY REPORT By G.

With the aim of harnessing the host response in 16 providing support to existing regimens, we used sertraline (SRT) to stunt the pro-pathogenic type 17 I IFN response of macrophages to infection. While SRT alone could only arrest bacterial growth, 18 it effectively escalated the bactericidal activities of Isoniazid (H) and Rifampicin (R) in 19 macrophages. This strengthening of antibiotic potencies by SRT was more evident in conditions 20 of ineffective control by these frontline TB drug, against tolerant strains or dormant Mtb. SRT, 21 could significantly combine with standard TB drugs to enhance early pathogen clearance from 22 tissues of mice infected with either drug sensitive/ tolerant strains of Mtb.

Purpose This protocol describes the mandatory steps to be taken in the treatment of tuberculosis (TB) cases in Queensland. The goal of clinical management of a TB case is to interrupt TB transmission, prevent acquisition of drug resistance, and cure the patient. 2. Scope This Protocol applies to all Hospital and Health Service (HHS) employees and organisations and individuals acting as an agent HHS’s (including Visiting Medical Officers and other partners, contractors, consultants and volunteers). 3. Process for the Diagnosis and Treatment of Tuberculosis 3.1 Case Management Model of Care • Each metropolitan or regional Tuberculosis Control Unit (TBCU) is to manage each TB case diagnosed within their jurisdiction under a case management team model • The TBCU case management team is responsible for the overall management of the patient which involves the TBCU checking that treatment regimens are correct and that appropriate follow up has been performed, and that all essential data has been provided by the treating team • The medical officer of the relevant TBCU is responsible for review of TB treatment regimens, in collaboration with the treating doctor, to ensure therapy adheres to best practice principles provided case has been notified to the TBCU. 3.1.1 Case Management Team • The case management team is comprised of the treating

Abstract: The control of tuberculosis (TB) is hampered by the emergence of multidrug-resistant (MDR) Mycobacterium tuberculosis (Mtb) strains, defined as resistant to at least isoniazid and rifampin, the two bactericidal drugs essential for the treatment of the disease. Due to the worldwide estimate of almost half a million incident cases of MDR/rifampin-resistant TB, it is important to continuously update the knowledge on the mechanisms involved in the development of this phenomenon. Clinical, biological and microbiological reasons account for the generation of resistance, including: (i) nonadherence of patients to their therapy, and/or errors of physicians in therapy management, (ii) complexity and poor vascularization of granulomatous lesions, which obstruct drug distribution to some sites, resulting in resistance development,
