objective(s): the quantitative calculation of release data is more facil when mathematics come to help. mathematically modeling could aid optimizing and amending the delivery systems design. aim of this study is to find out the isoniazid release kinetic. methods: in this work degradable temperature sensitive dextran-hydroxy ethyl methacrylate- poly-n-isopropyl acryl amide (dex-hema-pnipaam) nan...
BACKGROUND Isoniazid has been the backbone of tuberculosis chemotherapy for 6 decades. Resistance to isoniazid threatens the efficacy of treatment of tuberculosis disease and infection. To inform policies around treatment of tuberculosis disease and infection in children, we sought to estimate both the proportion of child tuberculosis cases with isoniazid resistance and the number of incident i...
A high performance liquid chromatographic method for simultaneous determination of isoniazid and acetyl isoniazid in urine was developed. Urine samples were filtered through Whatman number 1 filter paper and diluted filtrate was directly injected into C8 column (250mm). The mobile phase comprised of water and methanol in the ratio of 85:15. The analytes were detected at a wavelength of 274nm. T...
The molecular basis for isoniazid resistance in Mycobacterium tuberculosis is complex. Putative isoniazid resistance mutations have been identified in katG, ahpC, inhA, kasA, and ndh. However, small sample sizes and related potential biases in sample selection have precluded the development of statistically valid and significant population genetic analyses of clinical isoniazid resistance. We p...
background: tuberculosis is one of the infectious diseases worldwide that has resurgence by the aids epidemic and led to the rise of drug-resistant tuberculosis patients. thus, it seems essential to monitor the drug susceptibility in tuberculosis patients. the new high resolution melting (hrm) method is simple, rapid and inexpensive for detection of the mutations responsible for drug resistance...
BACKGROUND Isoniazid preventive therapy is a key public health intervention for the prevention of tuberculosis disease among people living with HIV. Despite the confirmed efficacy of isoniazid preventive therapy and global recommendations existing for decades, its implementation remains limited. In resource constrained settings, few have investigated why isoniazid preventive therapy is not impl...
To understand why once-weekly isoniazid/rifapentine therapy for tuberculosis was less effective than twice-weekly isoniazid/rifampin, we studied human immunodeficiency virus-seronegative patients with either failure (n = 4), relapse (n = 35), or cure (n = 94), recruited from a comparative treatment trial. In multivariate analyses that were adjusted for severity of disease, low plasma concentrat...
BACKGROUND Guidelines for latent tuberculosis infection do not consider drug-resistance patterns when recommending treatment for immigrant children. OBJECTIVES The purpose of this research was to decide at what rate of isoniazid resistance a different regimen other than isoniazid for 9 months should be considered. METHODS We constructed a decision tree by using published data. We studied 3 ...
BACKGROUND Isoniazid is the most widely used anti-tuberculosis agent, yet it may lead to life-threatening complications. CASE PRESENTATION Here we report the case of a chronic hemodialysis patient who developed severe encephalopathy after the start of isoniazid. Blood levels of isoniazid were elevated, and acetyl-isoniazid over isoniazid ratio was decreased 3 h after intake of the medication,...
Introduction: One of the main reasons for the development of the resistance in the therapy for Tuberculosis is the mono drug therapy. This may be due to the drug-drug interactions as the therapy includes combination of various drugs leading to poor bioavailability of these drugs. One such reported interaction is between Rifampicin and Isoniazid which leads to poor bioavailability of Rifampicin....
