Update on the Treatment of Tuberculosis - Article
ABSTRACT: Approximately one third of the world's population, including more than 11 million persons in the United States, is latently infected with Mycobacterium tuberculosis. Although most cases of tuberculosis in the United States occur in foreign-born persons from endemic countries, the prevalence is generally greater in economically disadvantaged populations and in persons with immunosuppressive conditions. Delays in detection and treatment allow for greater transmission of the infection. Compared with the traditional tuberculin skin test and acid-fast bacilli smear, newer interferon-gamma release assays and nucleic acid amplification assays lead to more rapid and specific detection of M. tuberculosis infection and active disease, respectively. Nine months of isoniazid therapy is the treatment of choice for most patients with latent tuberculosis infection. When active tuberculosis is identified, combination therapy with isoniazid, rifampin, pyrazinamide, and ethambutol should be promptly initiated for a two-month "intensive phase," and in most cases, followed by isoniazid and a rifamycin product for a four- to seven-month "continuation phase." Directly observed therapy should be used. Although currently limited in the United States, multidrug-resistant and extensively drug-resistant strains of tuberculosis are increasingly recognized in many countries, reaffirming the need for prompt diagnosis and adequate treatment strategies. Similarly, care of persons coinfected with human immunodeficiency virus and tuberculosis poses additional challenges, including drug interactions and immune reconstitution inflammatory syndrome.
ABSTRACT: High blood pressure is often difficult to control. Resistant hypertension is blood pressure above goal despite adherence to a combination of at least three antihypertensive medications of different classes, optimally dosed and usually including a diuretic. The approach to blood pressure that is apparently difficult to control begins with an assessment of the patient's adherence to the management plan, including lifestyle modifications and medications. White-coat hypertension may need to be ruled out. Suboptimal therapy is the most common reason for failure to reach the blood pressure goal. Once-daily fixed-dose combination pills may improve control through the synergism of antihypertensive agents from different classes and improved adherence. Truly drug-resistant hypertension is commonly caused by chronic kidney disease, obstructive sleep apnea, or hyperaldosteronism, all of which can lead to fluid retention. Higher doses of diuretics (or a change to a loop diuretic) are usually needed. Other strategies include adding an alpha blocker, alpha-beta blocker, clonidine, or an aldosterone antagonist (e.g., spironolactone). Particularly in patients with diabetes or renal disease, combining a long-acting nondihydropyridine with a dihydropyridine calcium channel . blocker can also be considered. Obesity, heavy alcohol intake, high levels of dietary sodium, and interfering substances (especially nonsteroidal anti-inflammatory drugs) contribute to hypertension that is resistant or difficult to control.
