Isoniazid, rifampicin, pyrazinamide, and ethambutol are commonly used for the treatment of tuberculosis. Drug exposure is occasionally associated with liver and/or skin injury. The aim of this study was to determine whether drug-specific T-cells are detectable in patients with adverse reactions and if so characterize the nature of the T-cell response. Peripheral blood mononuclear cells (PBMC) from 6 patients with anti-tuberculosis drug-related adverse reactions (4 liver, 2 skin) were used to detect drug-responsive T-lymphocytes. Positive lymphocyte transformation test and/or ELIspot results were observed with all 6 patients. Over 3400 T-cell clones were generated from isoniazid, rifampicin, pyrazinamide, or ethambutol-treated PBMC. CD4+ clones from all 3 patients were activated to proliferate and secrete cytotoxic mediators (granzyme B, perforin, FasL) and effector (IFN-γ, Il-13) and regulatory (Il-10) cytokines with isoniazid, but not rifampicin, pyrazinamide, or ethambutol. Il-17 was not detected, while only 1 clone secreted Il-22. Isoniazid-responsive clones were not activated with other anti-tuberculosis drugs or isonicotinic acid albumin adducts. Activation of the clones with isoniazid was MHC class II-restricted and dependent on antigen-presenting cells. Most clones were activated rapidly even in the presence of the enzyme inhibitor 1-aminobenzotriazole. However, a time-dependent pathway of activation involving auto-oxidation of isoniazid was also observed. The discovery of isoniazid-specific CD4+ T-cell clones in patients with liver and skin injury suggests that the adaptive immune system is involved in the pathogenesis of both forms of iatrogenic disease.

In a referred, consecutive sample of 173 patients identified as treatment failures on DOT-SCC, 160 (92.5%) had culture-positive TB. Of those 160, 150 (93.8%) had active, pulmonary multidrug-resistant TB (MDR-TB, resistance to at least isoniazid [INH] and rifampicin [RIF]). Sixty of the 150 (40.0%) had isolates resistant to at least INH, RIF, ethambutol (EMB) and pyrazinamide (PZA), the initial first-line empiric treatment regimen used locally. Forty-four (29.3%) had isolates resistant to at least INH, RIF, EMB, PZA and streptomycin (SM), the first retreatment regimen. This series of patients had isolates resistant to a mean of 4.5 of the ten drugs tested. The local profile of multidrug resistance is very different from that obtained from national data from Peru.

Mycobacterium marinum is an atypical mycobacterium usually found in non-chlorinated water. It rarely disseminates, except in the setting of a severely immunosuppressed patient, and usually follows a sporotrichotic type of distribution. We report the case of a 45-year-old man who had ankylosing spondylitis and was receiving infliximab and isoniazid for latent tuberculosis. The patient presented with a 5-month history of painful erythematous and suppurative nodules and abscesses on the right upper extremity. M. marinum was not isolated in cultures and histologic findings together with clinical examination provided evidence of sporotrichoid-like fish tank granuloma. The patient was treated with rifampin (rifampicin) and ethambutol for 8 months and responded satisfactorily while continuing to receive infliximab. In accordance with data in the published literature, isoniazid proved ineffective in preventing M. marinum infection in this patient. While mycobacterial complications of tumor necrosis factor-alpha (TNFalpha) inhibitor therapy are well established, our case appears to be the first reported instance of M. marinum infection in a patient taking infliximab. As anti-TNFalpha agents become increasingly used for a variety of conditions, awareness of the potential infectious complications associated with use of these agents will be vital for clinicians.

A 61-year-old woman received a cadaveric renal transplant in 1972 and was maintained on chronic immunosuppression. Nonspecific granulomatous synovitis of the left hand developed in 1982. After recurrence of synovitis in 1984, surgical exploration of the left hand demonstrated "rice bodies" in a region of chronic synovitis from which Mycobacterium kansasii was isolated. Despite therapy with isoniazid, rifampin, and ethambutol, to which the organism was susceptible in vitro, synovitis recurred. Recovery was completed after extensive synovectomies, decreased immunosuppression, and 24-months of therapy, with the drugs listed above; there was no evidence of mycobacterial infection at sites other than the left hand at any time. The occurrence of persistent Mycobacterium kansasii infection is distinctly unusual even in transplant recipients. In patients refractory to conventional antituberculous therapy, surgical management should be considered as an important therapeutic component.

Transmission of Mycobacterium bovis from cattle to humans has been reported and can cause tuberculosis (Tb) and a problem in certain risk populations. Therefore, knowledge of resistance of M. bovis towards antibiotics used for therapy of human Tb could help avoiding cure delay and treatment cost increase when dealing with drug resistant organisms. We therefore evaluated the susceptibility of M. bovis isolates towards streptomycin, isoniazide, rifampicin, ethambutol, and ethionamide, the first line antibiotics for human Tb. Therefore, 185 clinical samples from cattle with clinical signs of tuberculosis were processed and submitted to culturing and bacterial isolates to identification and drug susceptibility testing using the proportion method. Among 89 mycobacterial strains, 65 were identified as M. bovis and none were resistant to any of the antibiotics used. Confirmation of present results by future studies, enrolling a large number of isolates and designed to properly represent Brazilian regions, may favor the idea of using isoniazide preventive therapy as part of a Tb control strategy in special situations. Also, nucleic acids from bacterial isolates were submitted to rifoligotyping, a recently described reverse hybridization assay for detection of mutations causing resistance towards rifampicin. Concordance between the conventional and the molecular test was 100%, demonstrating the use of such methodology for rapid evaluation of drug susceptibility in M. bovis.

Tuberculosis of the rectum is rarely reported, even from areas where tuberculosis, and gastrointestinal tuberculosis in particular, is prevalent. The authors report a case of long tubercular stricture of the rectum and distal part of the sigmoid colon in a 12-year-old girl. Because of nonspecific symptoms and noncharacteristic radiological and endoscopic features, the diagnosis of this rare entity rests mainly on histological evidence of the classical tubercle in a surgical biopsy specimen.

The best six sampling timepoints in children were identified as 0 (pre-dose) and 0.42, 1.76, 3.37, 10.31 and 24 h post-dose. Thirty-one children were recruited and blood was drawn at these timepoints. Rifampicin, ethambutol and pyrazinamide were best described using a one-compartment model, while isoniazid was best described with a two-compartment model. Only 2/31 (6%), 20/31 (65%), 17/31 (55%) and 2/13 (15%) of children attained the WHO 2 h target therapeutic concentrations of rifampicin, isoniazid, pyrazinamide and ethambutol, respectively. Moreover, only 24/31 (77%), 6/31 (19%) and 8/31 (26%) achieved the AUCs associated with an optimal clinical response to rifampicin, pyrazinamide and isoniazid, respectively. No single risk factor was significantly associated with below-normal drug levels.

Multidrug resistance has become a problem in the management of tuberculosis, leading to an urgent need for research related to new regimens including the currently available drugs. The objectives of this study were: (i) to study the effect of the following second-choice three-drug combinations against multidrug-resistant (MDR) and drug-susceptible clinical isolates (levofloxacin, linezolid and ethambutol; levofloxacin, amikacin and ethambutol; and levofloxacin, linezolid and amikacin); and (ii) to compare the effect of these combinations with an isoniazid, rifampicin and ethambutol combination against drug-susceptible clinical isolates. A total of 9 MDR clinical and 12 drug-susceptible isolates (11 clinical isolates and the H37Rv reference strain) were studied using an adaptation of the chequerboard assay. The fractional inhibitory concentration index (FICI) was calculated as follows: FICI=FIC(A)+FIC(B)+FIC(C)=A/MIC(A)+B/MIC(B)+C/MIC(C), where A, B and C are the minimum inhibitory concentrations (MICs) of each antibiotic in combination and MIC(A), MIC(B) and MIC(C) are the individual MICs. The FICI was interpreted as synergism when the value was <0.75. The FICI of all the combinations ranged from 1.5 to 3, showing indifferent activity. No differences were found between MDR and drug-susceptible isolates, or between the second-choice combinations and the fourth combination against drug-susceptible isolates. In conclusion, the second-choice drugs are equally effective as the combination of isoniazid, rifampicin and ethambutol.

Mycobacterium malmoense is an opportunistic pathogen with increasingly recognized clinical importance. It is mainly isolated in northern Europe and Great Britain, most often from patients with pulmonary infections. Conventional therapy of M. malmoense infections with antituberculosis drugs is often of limited value, and there is thus a need for improved drug regimens. The potential efficacies of new alternative drugs, such as quinolones, macrolides, amikacin, and rifabutin, are still unknown, and so is the pathogen's in vitro susceptibility to most of these drugs. In this study, we used the BACTEC system for determining the pattern of resistance of clinical M. malmoense isolates to a number of antibacterial drugs as well as their possible synergistic interactions when each of them was combined with ethambutol. The majority of the strains were resistant or moderately resistant to the drug when it was tested alone at selected concentrations. However, pronounced in vitro synergism was demonstrated for combinations of ethambutol with ciprofloxacin, amikacin, and rifampin, rendering most isolates susceptible to the combined drugs. Thus, for in vitro susceptibility testing of M. malmoense, examination of the possible synergistic effects of combined drugs also can be recommended.

A 22-year-old Asian male presented with fever, non-productive cough, right-sided pleuritic chest pain and was found to have a large right hydropneumothorax. A chest tube was placed. Pleural fluid analysis revealed a lymphocytic predominant exudate and he was subsequently started on four-drug daily anti-tuberculosis therapy (isoniazid, ethambutol, rifampin, pyrazinamide). Pleural biopsy revealed acid-fast bacilli. Given his persistent pleural effusion, he was given four doses of intrapleural tissue plasminogen activator (tPA) and dornase alpha (DNase) via his chest tube over a period of 6 days resulting in clinical and radiologic improvement. Pleural biopsy and pleural fluid culture specimens later revealed Mycobacterium tuberculosis. Intrapleural tPA-DNase therapy has demonstrated improved resolution of infections and shortened hospitalizations for parapneumonic infectious effusions. However, there is little literature on the use of intrapleural fibrinolytics specifically for pleural tuberculosis associated effusions. Furthermore, the American Thoracic Society does not comment on therapeutic thoracentesis or intrapleural fibrinolytic therapy in their recommendations for treatment of pleural tuberculosis. In our case of pleural TB-associated hydropneumothorax, the use of intrapleural tPA-DNase therapy facilitated pleural fluid drainage and resulted in near-complete resolution of the effusion.

The contention and treatment of Mycobacterium tuberculosis and other bacteria that cause infectious diseases require the use of new type of antibiotics. Pandinin 2 (Pin2) is a scorpion venom antimicrobial peptide highly hemolytic that has a central proline residue. This residue forms a structural "kink" linked to its pore-forming activity towards human erythrocytes. In this work, the residue Pro14 of Pin2 was both substituted and flanked using glycine residues (P14G and P14GPG) based on the low hemolytic activities of antimicrobial peptides with structural motifs Gly and GlyProGly such as magainin 2 and ponericin G1, respectively. The two Pin2 variants showed antimicrobial activity against E. coli, S. aureus, and M. tuberculosis. However, Pin2 [GPG] was less hemolytic (30%) than that of Pin2 [G] variant. In addition, based on the primary structure of Pin2 [G] and Pin2 [GPG], two short peptide variants were designed and chemically synthesized keeping attention to their physicochemical properties such as hydrophobicity and propensity to adopt alpha-helical conformations. The aim to design these two short antimicrobial peptides was to avoid the drawback cost associated to the synthesis of peptides with large sequences. The short Pin2 variants named Pin2 [14] and Pin2 [17] showed antibiotic activity against E. coli and M. tuberculosis. Besides, Pin2 [14] presented only 25% of hemolysis toward human erythrocytes at concentrations as high as 100 µM, while the peptide Pin2 [17] did not show any hemolytic effect at the same concentration. Furthermore, these short antimicrobial peptides had better activity at molar concentrations against multidrug resistance M. tuberculosis than that of the conventional antibiotics ethambutol, isoniazid and rifampicin. Therefore, Pin2 [14] and Pin2 [17] have the potential to be used as an alternative antibiotics and anti-tuberculosis agents with reduced hemolytic effects.

We developed a new broth microdilution antimycobacterial susceptibility test for determination of minimum inhibitory concentration (MICs) using an air-dried microplate containing serially diluted antimicrobial agents and the modified Middlebrook 7H9 broth. The eight agents included were streptomycin (SM), isoniazid (INH), rifampicin (RFP), ethambutol (EB), kanamycin (KM), levofloxacin (LVFX), sparfloxacin (SPFX) and clarithromycin (CAM). Serial dilutions of the agents (128 micrograms/ml to 0.125 micrograms/ml) were prepared in microplates, and were reconstituted by inoculation of 0.2ml of cell suspensions (approximately 3 x 10(5) cells/ml). The test plates were incubated at 36 degrees C in 5% CO2, and the growth endpoints were read visually after 5-day, 7-day and 10-day incubations. Four ATCC reference strains, Mycobacterium tuberculosis, M. avium, M. kansasii and M. intracellulare, were repeatedly tested at three sites. Of 480 determination against eight agents, 455 (94.8%), 470 (97.9%) and 455 (94.8%) of the MICs read after 5-day, 7-day and 10-day incubations fell within 3log2 dilutions, respectively. The MICs gradually elevated during the incubation, however those of 7-day incubation were highly precise and easily determined. A total of 160 clinical isolates of M. tuberculosis and 114 of nontuberculous mycobacteria were tested against eight agents. As for the primary drugs (SM, INH, RFP and EB), most isolates of M. tuberculosis were highly susceptible with MIC90, < or = micrograms/ml. Both LVFX and SPFX were also active. The MICs against nontuberculous mycobacteria distributed in a wide range, and the activities of RFP, LVFX, SPFX and CAM were more potent. These results demonstrate this newly developed test method to be a practical, rapid, quantitative and nonradiometric alternative for the determination of MICs buy myambutol in clinical mycobacteriology laboratories.

In the years 1977-1980 290 patients were treated for pulmonary tuberculosis with standardized therapy: for the first five months isoniazid (INH), ethambutol (EMB) and rifampicin; INH and EMB were then continued for a total of up to 9-18 months (average 15 months). The patients' own physicians accepted the recommended duration of therapy in 85% of cases. During hospitalization, 96% of tests for INH in the urine were positive. Side effects, primarily consisting of elevated transaminases, were observed in 48% of the patients. 21-63 months after the beginning of therapy, reexamination of 220 of the patients showed 2 failures and 5 relapses. The relapses can be attributed to poor patient compliance (3 patients), a slow healing process with negative cultures only after 2 or more months of buy myambutol therapy (3 patients) and/or too short duration of therapy: 3 of the 7 patients treated for less than 9 months suffered relapses. Before administering short term therapy of 9 months or less in Switzerland it is necessary to take into consideration the age distribution, history and stage of the disease in the patients and our system of health care by family physicians.

Three methods for rapidly determining the susceptibility of Mycobacterium Tuberculosis isolates to isoniazid, rifampin, ethambutol, streptomycin, and para-aminosalicylic acid were evaluated in a large-scale, blind study. Two of the methods measured evolution of CO2 from radio-labeled substrate (14CO2), and one method measured incorporation of 3H-uracil into ribonucleic acid. Rapid indirect drug-susceptibility test results for nearly 300 isolates were compared with those obtained using a standard modified proportion technique. The 3H-uracil uptake method proved to be unacceptable. Over-all, the results obtained buy myambutol using the 14CO2 methods and the standard method were similar. In general, there was greater agreement between the 14CO2 and proportion techniques with drug-susceptible strains than with drug-resistant strains. Among drug-resistant strains, both 14CO2 methods were more reliable for determining resistance to rifampin than to other drugs. This study demonstrates that large-scale, blind evaluations of new laboratory procedures are valuable. Our results indicate that methods relying o the enzymatic release of 14CO2 should be further refined and evaluated.

Chitotriosidase, secreted by activated macrophages, is a biomarker of activated macrophages. In this study, we explored whether chitotriosidase could be adopted as a biomarker to evaluate the curative effect on tuberculosis (TB). Five counties were randomly selected out of 122 counties/cities/districts in Hunan Province, China. Our cases were all TB patients who were newly diagnosed or had been receiving treatment at the Centers for Disease Control (CDCs) of these five counties between April and August in 2009. Healthy controls were selected from a community health facility in the Kaifu district of Changsha City after frequency-matching of gender and age with the cases. Chitotriosidase activity was evaluated by a fluorometric assay. Categorical variables were analysed with the χ 2 test. Measurement data in multiple groups were tested with analysis of variance and least significant difference (LSD). Correlation between chitotriosidase activity and the degree of radiological extent (DRE) was examined by Spearman's rank correlation test. The average buy myambutol chitotriosidase activity levels of new TB cases, TB cases with different periods of treatment (6 months) and the control group were 54·47, 34·77, 21·54, 12·73 and 10·53 nmol/h.ml, respectively. Chitotriosidase activity in TB patients declined along with the continuity of treatment. The chitotriosidase activity of both smear-positive and the smear-negative pulmonary TB patients decreased after 6 months' treatment to normal levels (P < 0·05). Moreover, chitotriosidase activity was positively correlated with DRE (r = 0·607, P < 0·001). Our results indicate that chitotriosidase might be a marker of TB treatment effects. However, further follow-up study of TB patients is needed in the future.

For many years tuberculosis has been known to occur with greater frequency among persons with disorders that impair host defenses. In most instances these processes interfere with the immune response to Mycobacterium tuberculosis, whereas, in a few, such as silicosis, the probable abnormality is a nonimmune defect in macrophage function. Infection with the human immunodeficiency virus (HIV) causes progressive and ultimately profound depression of both humoral and cell-mediated immunity and, thus, is an extremely potent risk-factor for tuberculosis. Presumably the major effect of HIV infection that predisposes persons to developing tuberculosis is the reduction in circulating T-helper (CD4+) lymphocytes which causes a reduction in cytokine production and a consequent decrease in the functional capabilities of macrophages. However, a number of questions concerning pathogenesis of tuberculosis related to HIV remain. Available data suggest that the magnitude of the risk for developing tuberculosis among persons infected with both HIV and M. tuberculosis is very high, 8% in one prospective study. Because of the epidemic of HIV infection, the progressive downward trend in the incidence of tuberculosis in the United States has reversed and in 1989 there was a 5% increase in the number of cases. Preliminary data for 1990 suggest that there will be an 8 to 10% increase over 1989. Also in the United States approximately 3% of tuberculosis patients have been found to be HIV seropositive. The clinical features of tuberculosis in patients with HIV infection vary depending on the degree of immunosuppression. With mild immunosuppression early in the course of HIV infection tuberculosis presents in a "typical" way with positive tuberculin skin tests, upper lobe cavitary infiltrates on chest film and positive sputum smears and cultures. As the HIV infection progresses, the mode of presentation of tuberculosis becomes more "atypical" with negative skin tests, multiple sites of involvement, chest films showing diffuse noncavitary infiltrates often accompanied by intrathoracic lymphadenopathy. The key to diagnosis is maintaining a high index of suspicion for tuberculosis, especially in patients with advanced HIV disease and including appropriate laboratory examinations in the evaluations of such persons. Regardless of the stage of HIV infection the response to treatment for tuberculosis is generally favorable if buy myambutol it is begun promptly. Standard therapy utilizing isoniazid, rifampin, and pyrazinamide with or without ethambutol have been associated with high rates of cure. Relapse has been uncommon. There has been, however, at least one outbreak of tuberculosis caused by isoniazid and rifampin resistant organisms in which the response to therapy was very poor.(ABSTRACT TRUNCATED AT 400 WORDS)

An 80-year-old woman presented with rapid, progressive and multiple cavitary lesions in both lungs. Rheumatoid arthritis had been diagnosed and been treated with prednisolone (5 mg/day) and bucillamine since 1996. Due to worsening of arthralgia, methotrexate (6 mg/week) and leflunomide (10 mg/day) had been added to the medication since 2003. In April 2005, her chest radiography revealed multiple cavities and nodules predominantly in both upper lung fields, although she complained of no respiratory symptoms. No pathogenic organisms were found, and the cavitary and nodular buy myambutol shadows were increased rapidly within the next 2 months. Therefore, the patient was referred to our hospital in July 2005. Repeat microbiologic findings of sputum were negative for bacteria and fungi, except for Mycobacterium avium (M. avium). She was given a diagnosis of M. avium lung disease, and it seemed to be associated with her compromised status caused by disease modifying anti-rheumatic drugs (DMARDs). She was then successfully treated with combined chemotherapy employed clarithromycin, rifampicin, ethambutol and streptomycin. So far, rapid and progressive deterioration of non-tuberculous mycobacterial lung disease accompanied with an intake of DMARDs had not been reported in Japan. An increase of M. avium complex lung disease in the elderly is now becoming a problem among respiratory physicians. This case highlights the fact that patients who are scheduled to be given DMARDs, particularly elderly case, should be considered to be at an elevated risk of developing non-tuberculous mycobacterial (NTM) lung disease, and the risk of NTM infection should be excluded before prescribing drugs.

The aim of this double-blind, randomized, placebo-controlled, 12-week study was to assess the efficacy of rifabutin (450 or 600 mg/d) in the treatment of disseminated nontuberculous mycobacterial infection in patients with AIDS. Companion drugs in both arms of the study were ethambutol, clofazimine, and isoniazid. Because of low accrual, the study was prematurely terminated when a total of 382 patients had been enrolled, of which 200 were eligible (i.e., their specimens were culture-positive for Mycobacterium avium complex [MAC] or Mycobacterium xenopi at baseline) and 102 were evaluable (i.e., they were eligible, were treated for a Exelon Drug Class minimum of 6 weeks, and had at least one culture assessment after baseline). The original protocol called for a total of 220 evaluable patients. At week 12, rifabutin treatment was associated with higher, although nonsignificant, rates of bacteriologic conversion than was the placebo arm, with regard to both the eligible patients (25% vs. 18%) and the evaluable patients (45% vs. 38%). Corresponding median times to culture conversion were 42 vs. 63 days (eligible patients) and 43 vs. 69 days (evaluable patients). No significant difference was observed in clinical improvement, mortality, or toxicity between the two treatment arms. The addition of rifabutin to a triple-drug regimen may contribute to the clearance of disseminated MAC infection in patients with AIDS, without causing additional toxicity.

Hemophagocytic syndrome (HPS) in systemic lupus erythematosus(SLE) patients has not commonly been reported. In this case study, we report the first case of Mycobacterium avium complex (MAC)-associated hemophagocytic syndrome in a patient with systemic lupus erythematosus (SLE). This SLE patient, a 15-year-old girl, had been on a high dose of prednisolone (> 0.5mg/kg/day) for more than 3 Cymbalta Antidepressant Drug years. She presented with a spiking fever, hepatosplenomegaly, pancytopenia, hyperferritinemia and adult respiratory distress syndrome. Bone marrow examination revealed hemophagocytosis as well as non-caseating granulomatosis. There was no indication of SLE fare-up. She responded poorly to initial treatment with methyl-prednisolone, intravenous immumoglobulin, etoposide, and drugs for Mycobacterium tuberculosis including rifampin, ethambutol, isoniazid and pyramide. However, gastric lavage culture revealed MAC. Following treatment with clarithromycin, ciprofloxacin and amikacin, her condition gradually improved and she was discharged 3 months after admission. In SLE patients with pancytopenia and hyperferritinemia, MAC-associated HPS should be considered in the differential diagnosis.

M. tuberculosis isolates were obtained from consenting adult tuberculosis patients involved in a placebo-controlled study to evaluate the efficacy of multivitamin supplements on response to anti-Tb treatment in Dar es Salaam, Tanzania. Antimicrobial susceptibility testing was done on four antimicrobial agents namely streptomycin, isoniazid, ethambutol and rifampicin. HIV testing and CD4+ T lymphocytes enumeration were also done. A total of 280 M. tuberculosis isolates from 191 (68%) males and 89 (32%) female patients with no previous history of anti-tuberculosis treatment exceeding 4 weeks in the previous 12 months were tested. Among these, 133 (47%) patients were HIV seropositive. Fourteen (5.0%) isolates were resistant to any of the anti-tuberculosis drugs. The prevalence of Dandruff Nizoral Reviews primary resistance was 5.0%, 0.7%, 0.4% and 0% for isoniazid, streptomycin, rifampicin and ethambutol respectively. One isolate (0.4%) was MDR, with resistance to isoniazid, streptomycin and rifampicin.

M. bovis, the agent of bovine tuberculosis, was in other times, Propecia Dosage Instructions the main ethiological agent of tuberculosis (TBC) in industrialized countries. At the moment, the human cases have become not very frequent, except in those countries where the illness is even endemic. In patients with immunodeficiency syndrome, it usually presents as a systemic illness. We present the case of a woman with AIDS and disseminated TBC caused by M. bovis. The isolated micobacteria turned out to be resistant to rifampin and pyrazinamide. She was treated with isoniazid, ethambutol and ofloxacin with good clinical evolution. This case turned out to be the first isolation of M. bovis in a patient with AIDS, in Muñiz hospital.

The developing countries are having an abruptly growing number of drug resistant tuberculosis cases. Multidrug-resistant tuberculosis (MDR-TB) is a type of TB in which the strain of Mycobacterium tuberculosis is resistant to at least Isoniazid and Rifampicin, the two most effective of the four first-line TB drugs (the other two drugs being Ethambutol and Pyrazinamide). The management of such cases is complex and requires a treatment for 24-27 months. The current guidelines available for the management of this type of TB are largely based on the Geodon Dosage second line TB drugs which are relatively costly, less efficacious and are associated with greater side-effects. The introduction of newer drugs to cater to the high mortality and early sputum culture conversion in the MDR-TB cases is an absolute essential. In the present article, the authors discuss about the introduction of a newer drug named Bedaquiline for the control of MDR-TB.

Drug resistance of Mycobacterium tuberculosis was followed up within a period of 1986 to Paracetamol Y Alcohol 1989. There was a tendency to stabilization of resistance to streptomycin (42 per cent), tubazid (45.2 per cent) and ethionamide (up. to 1.4 per cent). Resistance to kanamycin slowly increased (by 3 to 6 per cent every year). Resistance to rifampicin markedly increased (almost 15 times). Resistance to ethambutol decreased (10 times). It was shown that the drug resistance could be lowered by using the drug combinations.

A case of central retinal vasculitis associated with culture proven active pulmonary tuberculosis is presented. The ocular condition responded dramatically to systemic isoniazid and ethambutol. The clinical picture of central retinal vein occlusion should alert the physician to the possibility of an inflammatory etiology. Appropriate studies to rule out treatable inflammatory conditions should be ordered.

We investigated the pharmacokinetics of rifampicin and its major metabolites, 25-desacetylrifampicin and 3-formylrifampicin, in two groups of six patients with active pulmonary tuberculosis, who received either multiple oral or intravenous rifampicin therapy in combination with intravenous isoniazid and ethambutol. Serum concentrations of rifampicin were each determined after a single oral and intravenous test dose of 600 mg rifampicin at the beginning and after 1 and 3 weeks of tuberculostatic treatment. Analysis of rifampicin and its metabolites was performed by high-pressure liquid chromatography. It was found that, due to autoinduction of its metabolizing hepatic enzymes, the systemic clearance of rifampicin increased from 5.69 to 9.03 l/h after 3 weeks of multiple dosing. The volume of distribution of the drug was constant over the period of this study. The bioavailability of the active, orally administered rifampicin decreased from 93% after the first single oral dose to 68% after 3 weeks of oral and intravenous rifampicin therapy. Relating to the increase in systemic (hepatic) clearance, a bioavailability no lower than 90% can be predicted. The reduction to 68% indicates that, in addition to an increase of hepatic metabolism, an induction of a prehepatic "first-pass" effect resulted from multiple rifampicin doses. Our study of rifampicin metabolites confirm that prehepatic metabolism was induced, since a higher metabolic ratio resulted after the oral doses than after the intravenous rifampicin test doses. A preabsorptive process can therefore be excluded as a cause of reduced bioavailability.

Three hundred and twenty-nine patients with isoniazid-resistant cultures, 66% with radiographically far advanced disease and 86% with cavities, have been treated with rifampicin and ethambutol and followed-up for 2 years after the end of treatment. The drugs were given daily for 12 weeks (600 mg rifampicin and 25 mg/kg ethambutol), thereafter once- or twice-weekly (600 or 1200 mg rifampicin and 50 mg/kg ethambutol) for a total of 12, 18 or 24 months (in the 600 mg group for 12 months only). With both 600 and 1200 mg rifampicin dosage the bacteriological results at the end of a year were similar (5% bacteriologically unfavourable in each group). Prolonging treatment to 18 or 24 months with the 1200 mg rifampicin dose had no effect on the bacteriological results. During the 2 years follow-up period after treatment stopped 6 patients had a bacteriological relapse. Of the 74 with a favourable status after 1 year in the 600 mg rifampicin group 5 (6.7%) relapsed, but only 1 (0.6%) of 168 in the 1200 mg groups treated for 12, 18 or 24 months (the duration of treatment did not appear to be related to relapse). Side-effects were reported more frequently with once-weekly dosage. They were more frequent with 1200 mg rifampicin than with 600 mg and with the former dose more frequent in the groups treated for longer than 1 year. With 12 months treatment with 600 mg rifampicin only 1% of patients had to have the regimen changed; with 1200 mg it was 9% and with this dose for 24 months 20%. With the lower dosage of rifampicin there were fewer failures due to toxicity but more failures due to relapse. Of 82 patients in the 600 mg regimen there were 12% unfavourable results (4 bacteriological failures, 5 relapses and 1 change of treatment for toxicity). Of 78 patients in the 1200 mg regimen there were 13% unfavourable results (3 bacteriological failures, no relapses and 7 changes of treatment for toxicity).
