BACKGROUND Rifampicin induces expression of the cytochrome P450 isoenzyme 2B6 (CYP2B6), which metabolizes efavirenz. The CYP2B6 516G>T polymorphism impairs efavirenz metabolism and occurs more commonly in Africans than in Caucasians. We explored the effect of rifampicin-based antitubercular therapy and the 516G>T polymorphism on efavirenz concentrations in HIV-infected patients in South Africa....

In this study, a case with tubercular choroiditis showing severe macular edema and progression of choroidal lesions following initiation of antitubercular treatment is presented and the management of posterior uveitis associated with tuberculosis is evaluated. A 40-year-old female patient was admitted with decreased vision in her right eye and her fundoscopic examination revealed serpiginous ch...

A series of 14 patients suffering from tuberculosis of the sternum with a mean follow-up of 2.8 years (2 to 3.6) is presented. All were treated with antitubercular therapy: ten with primary therapy, two needed second-line therapy, and two required surgery (debridement). All showed complete healing and no evidence of recurrence at the last follow-up. MRI was useful in making the diagnosis at an ...

Tuberculosis was declared as a global pandemic and panic because the causative Mycobacterium tuberculosis can kill an incredible number of individuals which formulate a major obstacle to social and economic development of the country. Most of the developing countries are affected by tuberculosis. Antitubercular therapy involves the use of Directly Observed Therapy Short (DOTS) course for 6-9 mo...

Pulmonary tuberculosis remains the commonest form of this disease and the development of methods for delivering antitubercular drugs directly to the lungs via the respiratory route is a rational therapeutic goal. The obvious advantages of inhaled therapy include direct drug delivery to the diseased organ, targeting to alveolar macrophages harbouring the mycobacteria, reduced risk of systemic to...

There has been considerable interest in various analogues of antitubercular drugs particularly against multidrug and extensively drug resistant tuberculosis because mycobacterium species has developed resistant against available drugs. The currently used antitubercular also causes some serious toxic effects and also require long period of therapy for the treatment. Therefore, various new drugs ...

BACKGROUND Longitudinally extensive transverse myelitis is characterized by contiguous inflammatory lesion of spinal cord involving three or more spinal segments. It is a well-recognized but rare presentation of Mycobacterium tuberculosis infection. CASE DESCRIPTION We report a case of young boy diagnosed with multiple brain tuberculomas. He was on antitubercular drugs therapy for 2 months an...
