When and how to treat pulmonary non-tuberculous mycobacterial diseases. Categorical variables were analyzed using the Pearson χ2-test or Fisher exact test. Polyclonal, Wallace RJ Jr, Zhang Y, Brown-Elliott BA, Yakrus MA, Wilson RW, Mann L, Couch L, Girard WM, Griffith DE. The decision is relatively easy in patients with profound symptoms and destructive lesions; however, the decision is difficult in patients with mild symptoms and non-advanced lesions. For the treatment of M. abscessus lung disease, clarithromycin administration plus at least one other agent to which the organism is susceptible may follow initial therapy. Madrid. NTM are found in the soil, air, and water, so you can get an infection from swimming, gardening, or breathing air with NTM. Two patients were diagnosed at 14 and 26 months, respectively, after the initiation of antibiotic therapy, and one patient was diagnosed at 9 months after the completion of antibiotic treatment for M. abscessus lung disease. Pulmonary Mycobacterium abscessus: can we identify the road to improved outcomes. All patients met the diagnostic criteria for NTM lung disease, according to the ATS guidelines in 1997 (1).

Pulmonary disease caused by Mycobacterium abscessus (MAB-PD) is of particular interest as, when coupled with underlying lung disease, it is associated with rapidly declining lung function, significant morbidity and mortality, and particularly poor treatment outcomes: cure, as generally defined by persistent culture conversion, is generally reported to be found in less than 50% of cases in … Nam HS, Koh WJ, Kwon OJ, Cho SN, Shim TS. The ATS guidelines (1997) and ATS/IDSA guidelines (2007) recommend treating patients with clarithromycin in combination with high-dose cefoxitin and low-dose amikacin (1, 2). Viral infections, such as measles, can have severe sequela… Thank you for your interest in spreading the word on European Respiratory Society . More than 120 species of mycobacteria have been identified that can cause disease in humans. In contrast to clarithromycin, no such relationship was found for amikacin, cefoxitin, ciprofloxacin, or doxycycline in this study. Mycobacterium abscessus is a non-tuberculous mycobacterium increasingly recognized as an opportunistic pathogen in CF patients. †High off-scale MICs were converted to the next-highest concentration. Follow-up HRCT scans were performed at a median 12.2 months (IQR, 11.9–12.5 mo) after the start of antibiotic therapy.

Mycobacterium abscessus es una micobacteria de crecimiento rápido contaminante común del agua. However, linezolid was not used at our institution for the treatment of NTM lung disease because of high costs and side effects such as peripheral neuropathy and bone marrow suppression (30, 31). 2003. However, another recent study revealed that the activity of clarithromycin against M. avium complex strains could be attenuated by combination with a fluoroquinolone in both in vitro and in vivo models (26). Informed consent was waived because of the retrospective nature of the study. Despite their efforts, they acknowledge several limitations from this work, particularly their inability to derive data from six eligible studies, and the wider difficulties inherent in meta-analyses involving relatively low patient numbers. We used a clarithromycin-containing three-drug oral regimen because of our concern for the emergence of clarithromycin resistance during clarithromycin monotherapy after discharge from the hospital after the initial 4-week therapy (21, 22). *Favorable microbiologic response was defined as sputum conversion and the maintenance of negative sputum cultures for more than 12 months. NTM species were identified using a polymerase chain reaction and restriction length polymorphism method based on the rpoB gene, as previously described (9). Interestingly, some experts suggest that “holding” regimens of a macrolide plus a fluoroquinolone may be helpful for periods between the pulsed intravenous antibiotic therapies, even if in vitro susceptibility results reveal resistance to the fluoroquinolones (24). Imipenem displayed in vitro activity against a moderate number of isolates (48%, 20/42). Currently, we are using two-drug regimens including clarithromycin and moxifloxacin after the initial parenteral therapy. 1. They demonstrated that overall treatment success for MAB-PD was 45.6% (95% CI 26.7–64.4). Some of the results of this study have been previously reported in the form of abstracts (11, 12). We characterized the lung immune responses in mice and guinea pigs infected with M. abscessus.C57BL/6 and leptin‐deficient ob/ob mice challenged with a low‐dose aerosol (LDA) of M. abscessus did not develop an infection. Sputum relapse was defined as two consecutive positive cultures after sputum conversion (18). This is an open-label study of efficacy, safety and tolerability of once daily dosing of Liposomal-Amikacin for Inhalation (LAI), in addition to a standard multi-drug antibiotic therapy in accordance with the 2007 ATS/ IDSA guidelines, in patients with Mycobacterium abscessus lung disease. Objectives: To assess the efficacy of a standardized combination antibiotic therapy for the treatment of M. abscessus lung disease. MAC encompasses three mycobacterial species known as M. avium,M. aureus, Haemophilus influenzae, Pseudomonas aeruginosa, Strep. TABLE 2. In 28 of these 39 patients, imipenem was administered as a substitute for cefoxitin during the remaining 4 weeks of hospitalization. Additionally, if we are to better understand which treatment regimens offer the greatest chance of success, there is a need for consistency in approach to defining the end-points by which we measure treatment success. A total of 65 patients (10 males and 55 females; median age, 55 yr [IQR 43–63 yr]) with M. abscessus lung disease who received combination antibiotic therapy for more than 12 months were included in the study. Nontuberculous mycobacteria (NTM) are a heterogeneous group of organisms that occasionally are a primary cause of lung disease but more commonly affect patients with underlying chronic lung disease such as bronchiectasis, pneumoconiosis, or healed tuberculosis (1, 2). Thomson RM, Yew WW. Olaison L, Belin L, Hogevik H, Alestig K. Incidence of β-lactam-induced delayed hypersensitivity and neutropenia during treatment of infective endocarditis. Because the majority of the data did not follow a normal distribution, all results in the text or tables are expressed as the median and IQR, or as the number (percentage) of patients. At the start of treatment, the median ESR was 45.0 mm/h (IQR, 27.5–73.0 mm/h). Koh WJ, Yu CM, Suh GY, Chung MP, Kim H, Kwon OJ, Lee NY, Chung MJ, Lee KS. Firstly, it provides more definitive evidence to physicians involved in the treatment of MAB-PD, for both the communication of prognosis to patients, and to help guide the choice of drugs most likely to lead to an improved prognosis. Griffith DE, Girard WM, Wallace RJ Jr. Clinical features of pulmonary disease caused by rapidly growing mycobacteria. If an adverse reaction associated with cefoxitin occurred, imipenem (750 mg, three times a day) (3) was substituted for cefoxitin. abcessus puede causar enfermedad crónica pulmonar, infeccón de heridas postraumáticas, enfermedad cutánea diseminada principalmente en pacientes inmunodeprimidos. Age and body mass index did not differ significantly between female and male patients. Olaison L, Alestig K. A prospective study of neutropenia induced by high doses of β-lactam antibiotics. Permission was obtained from the institutional review board of Samsung Medical Center to review and publish information from the patients' records. CONCLUSIONS: Mycobacterium abscessus infection in LTR is rare and can lead to severe complications. Cremades R, Santos A, Rodriguez JC, Garcia-Pachon E, Ruiz M, Escribano I, Royo G. Screening for sterilizing activity of antibiotic combinations in an acid model of rapidly growing mycobacteria during the stationary phase of growth. Of those, Mycobacterium abscessus appears in 16 to 68 percent of cases. Introduction. The optimal therapeutic regimen and duration of treatment for Mycobacterium abscessus lung disease is not well established. Kohno Y, Ohno H, Miyazaki Y, Higashiyama Y, Yanagihara K, Hirakata Y, Fukushima K, Kohno S. In vitro and in vivo activities of novel fluoroquinolones alone and in combination with clarithromycin against clinically isolated. Although M. abscessus complex most commonly causes chronic lung infection and skin and soft tissue infection (SSTI), the complex can also cause infection in almost all human organs, mostly in patients with … The administered drugs included amikacin (58%), cefoxitin (43%), erythromycin (31%), and antituberculosis agents (37%) (6). Chest radiography and high-resolution computed tomography (HRCT) findings were classified as showing either upper lobe cavitary disease or nodular bronchiectatic disease (15). Thus, the nomenclature of M. abscessus in the present study was referred to the M. abscessus group, which is now divided into three species: M. abscessus, M. massiliense and M. bolletii. Koh WJ, Kwon OJ, Jeon K, Kim TS, Lee KS, Park YK, Bai GH. Negative conversion of sputum was achieved and maintained for more than 12 months in 58% (38/65) of patients. In November 2011, her CXR and computed tomography scan (Fig. Fourth, drug susceptibility results were available in only 69% (45/65) of patients. The decision to commence treatment is determined according to the severity of the disease, risk of progressive disease, presence of comorbidities, and goals of treatment. Of these 38 patients, 32 patients completed antibiotic treatment and were followed for a median of 11.9 months (IQR, 5.3–20.7 mo) without relapse. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Wallace RJ Jr, Brown-Elliott BA, Ward SC, Crist CJ, Mann LB, Wilson RW. The roles of combined activities of fluoroquinolones with clarithromycin against M. abscessus are controversial. Three (5%) patients, who presented with the upper lobe cavitary form of M. abscessus lung disease had complications of chronic necrotizing pulmonary aspergillosis. Enter multiple addresses on separate lines or separate them with commas. TABLE 4. These germs are commonly found throughout the environment. Definition of abbreviations: CI = confidence interval; OR = odds ratio. Our treatment strategy for patients with M. abscessus lung disease is divided into two paths: reservation of antibiotic therapy for patients with mild forms of the disease and initiation of aggressive antibiotic therapy with standardized regimens for patients with severe or progressive forms of the disease. The present study has several limitations. Additional detail on the method is provided in an online data supplement. However, when challenged with a high‐dose aerosol (HDA), … TABLE 5. In addition, the broth microdilution MIC determination method had not yet been established in Korea during the early study period. After the establishment of a reliable drug susceptibility test, we found that the fluoroquinolones, such as ciprofloxacin and moxifloxacin, showed moderate in vitro activity against M. abscessus isolates from patients, whereas doxycycline showed very weak in vitro activity (23). Definition of abbreviations: AFB = acid-fast bacilli; IQR = interquartile range. By continuing to browse In three patients who underwent surgical resection of localized disease and achieved sputum negative conversion, treatment finished at 13, 19, and 20 months, respectively. Mycobacterium abscessus lung disease recurred in 5 (15%) patients after successful completion of antibiotic therapy. Finally, as the authors illustrate, this is the first individual patient data meta-analysis in the NTM-PD field, but was ultimately only able to include 303 patients. Chronic lung disease as a result of Mycobacterium abscessus is an emerging infection in the United States. The decision to start antibiotic therapy is made by weighing the anticipated benefits and risks. Mycobacterium tuberculosis was not isolated. However, the patients did not receive the currently recommended combination of antibiotics, which includes newer macrolides such as clarithromycin. After the discontinuation of cefoxitin, the above adverse reactions resolved completely. Mycobacterium abscessus accounts for approximately 65 to 80% of lung disease caused by RGM (5–8). Wallace RJ Jr, Meier A, Brown BA, Zhang Y, Sander P, Onyi GO, Bottger EC. Of the parenteral antibiotics, cefoxitin (98%, 44/45) and amikacin (96%, 43/45) were active against most isolates. Mycobacterium abscessus was thought to be a colonizer in the diseased lung and anti‐TB chemotherapy was continued until October 2010. Nucleotide-binding oligomerization domain (NOD) 2 is a cytosolic receptor which senses a bacterial peptidoglycan component, muramyl dipeptide (MDP). Wallace RJ Jr, Swenson JM, Silcox VA, Good RC, Tschen JA, Stone MS. Complete blood cell counts, serum creatinine, and liver function test results were monitored twice a week during hospitalization. Sputum conversion was defined as three consecutive negative cultures within 6 months, with the time of conversion defined as the date of the first negative culture. Pulmonary disease caused by Mycobacterium abscessus (MAB-PD) is of particular interest as, when coupled with underlying lung disease, it is associated with rapidly declining lung function, significant morbidity and mortality, and particularly poor treatment outcomes: cure, as generally defined by persistent culture conversion, is generally reported to be found in less than 50% of cases in published data [4, 5]. These rates were significantly lower in patients whose isolates were resistant to clarithromycin (17%, 2/12) compared with those whose isolates were susceptible or intermediate to clarithromycin (64%, 21/33; P = 0.007). M. abscessus is resistant to many antibiotics and thus is very difficult to treat. Isolates are usually susceptible only in vitro to the parenteral agents amikacin, cefoxitin, and imipenem, and to oral macrolides (clarithromycin and azithromycin) (1, 2). massiliense and M. abscessus subsp. M. abscessus was the most commonly NTM species cultured, representing 298 (55.6%) of the isolates; Mycobacterium avium complex was second with 190 (35.4%) isolates (Fig. Close observation is indicated if the decision is made not to treat. Sputum smear and culture examinations were performed monthly for the first 6 months and then at 2- to 3-month intervals until the end of treatment. Pulmonary TB and NTM lung disease: comparison of characteristics in patients with AFB smear-positive sputum. The findings of this meta-analysis suggest that specific targeted therapy for Mycobacterium abscessus subspecies abscessus can improve treatment outcomes, and may help to design future antimicrobial drug regimens in this difficult to treat lung infection http://bit.ly/2WOFsRw. Has anyone ever been cured from this? Personalized treatment regimens could be designed based on in vitro drug susceptibility testing results of bacilli in an individual patient. Adekambi T, Berger P, Raoult D, Drancourt M. Kim HY, Kook Y, Yun YJ, Park CG, Lee NY, Shim TS, Kim BJ, Kook YH.
