Negative sputum culture conversion was achieved within a median duration of 1.5 months (IQR, 1.0–2.0 mo) postoperatively and was maintained in seven (88%) of eight patients with preoperative culture-positive sputum. The precise mode of transmission of environmental myco-bacteria such as M. abscessus into the lungs is not known, Mycobacterium abscessus accounts for approximately 65 to 80% of lung disease caused by RGM (5–8). Surprisingly, limited data are available in the literature regarding the clinical efficacy of this combination antibiotic therapy for M. abscessus lung disease. en pacientes con fibrosis quística. Therefore, the microbiologic response rate, which was defined as sputum conversion and the maintenance of negative sputum cultures for more than 12 months, was significantly lower in patients infected with clarithromycin-resistant isolates (17%, 2/12) compared with patients infected with clarithromycin-susceptible or intermediate isolates (64%, 21/33; P = 0.007) (Table 6). National Committee for Clinical Laboratory Standards. Identificación rápida de . Personalized treatment regimens could be designed based on in vitro drug susceptibility testing results of bacilli in an individual patient. Gastrointestinal symptoms (e.g., anorexia, nausea, or diarrhea) associated with oral antibiotic usage after discharge from the hospital occurred in 14 (22%) patients. After discharge, patients took a three-drug oral regimen for a total treatment duration of 24 months. Clínicamente, las infecciones por micobacterias no tuberculosas se manifiestan como enfermedad pulmonar, ganglionar, enfermedad diseminada, afectación de piel … †High off-scale MICs were converted to the next-highest concentration. Combination therapy of intravenous amikacin with cefoxitin or imipenem and an oral macrolide have been recommended by the American Thoracic Society (ATS)/Infectious Diseases Society of America (IDSA) and many other experts (1–4). 2003. Sputum smears and mycobacterial cultures were performed with standard methods (13). The guidelines state that administration of this combination therapy for 2 to 4 weeks (1) or 2 to 4 months (2) usually produces clinical and microbiologic improvement; however, cost and morbidity are significant impediments to a curative course of therapy (likely 4–6 mo). Al paciente se le indicó . Lam PK, Griffith DE, Aksamit TR, Ruoss SJ, Garay SM, Daley CL, Catanzaro A. Drug-induced hepatotoxicity occurred in 10 (15%) patients. Conclusions: Standardized combination antibiotic therapy was moderately effective in treating M. abscessus lung disease. In three patients who underwent surgical resection of localized disease and achieved sputum negative conversion, treatment finished at 13, 19, and 20 months, respectively. 2) showed further enlarged upper lobe cavities associated with increased adjacent lung infiltrates. ATS/IDSA recommendations suggest that susceptibility to some agents, such as amikacin, cefoxitin, clarithromycin, ciprofloxacin, and doxycycline, should be reported and used to guide treatment (1, 2). E-mail: American Journal of Respiratory and Critical Care Medicine. Mycobacterium abscessus is greatly associated with lung infection among patients with bronchiectasis, and is an important cause of morbidity among this patient population. Wallace RJ Jr, Swenson JM, Silcox VA, Good RC, Tschen JA, Stone MS. Differences in observed findings were resolved by consensus based on five radiographic features: cavitary disease, bronchiectasis, nodules, consolidation, and tree-in-bud appearance (16). None of the 65 patients tested positive for human immunodeficiency virus. con un score de 1,967. Es un grupo de micobacterias no tuberculosas … Age and body mass index did not differ significantly between female and male patients. Our treatment regimen included an initial 4-week regimen of intravenous cefoxitin and amikacin administration. In addition, the administration of intravenous cefoxitin for 4 weeks was frequently associated with adverse reactions, such as neutropenia. Informed consent was waived because of the retrospective nature of the study. abscessus, M. abscessus subsp. In addition, M. bolletii was reported to be naturally resistant to clarithromycin (36, 39). Our study results suggest that, for clarithromycin, there is a strong correlation between in vitro and in vivo results.

For definition of abbreviations, see Table 1. Colombo RE, Olivier KN. Imipenem may be a reasonable alternative to cefoxitin (2), but neutropenia can also occur with prolonged administration. Therefore, the isolates recovered from only 45 (69%) of 65 patients could be tested for susceptibility to antibiotics. Han XY, De I, Jacobson KL. However, frequent adverse reactions and the potential for long-duration hospitalization are important problems that remain to be solved. Sputum conversion rates were lower in patients whose isolates were resistant to clarithromycin (42%, 5/12) compared with those whose isolates were susceptible or intermediate to clarithromycin (76%, 25/33). Yet expert guidelines, such as those from the American Thoracic Society/Infectious Diseases Society of America [7], and the British Thoracic Society [8], vary in recommended antibiotic strategies, ultimately muddying the waters when it comes to choosing the most efficacious therapies. American Thoracic Society. In patients with substantial symptoms and/or advanced or progressive radiographic abnormalities, antibiotic therapy was initiated immediately. At the start of treatment, the median ESR was 45.0 mm/h (IQR, 27.5–73.0 mm/h). Of the parenteral antibiotics, cefoxitin (98%, 44/45) and amikacin (96%, 43/45) were active against most isolates. Eradication is difficult and usually requires prolonged combination antibiotic therapy and occasionally surgical management. Conflict of interest: D.W. Connell has nothing to disclose. In addition, the inducible macrolide resistance and inducible erm gene, which provide an explanation for the lack of efficacy of macrolide-based treatments (42), were not determined in our study. To our knowledge, there has been no published study for more than 15 years that has focused on the antibiotic treatment of M. abscessus lung disease in a large sample of patients. Sputum conversion and maintenance of negative sputum cultures for more than 12 months was achieved in 38 (58%) patients. We retrospectively reviewed our prospectively collected institutional adult lung transplant database from 2001 to 2015 to identify patients with M. abscessus or Mycobacterium chelonae/abscessus infection before or after transplantation. TREATMENT OF 65 PATIENTS WITH MYCOBACTERIUM ABSCESSUS LUNG DISEASE. Specifically, optimal therapeutic regimens and treatment durations are not well established. It is part of a group of environmental mycobacteria and is found in water, soil, and dust. Introduction. Nontuberculous mycobacterial (NTM) lung infections are caused by NTM, most commonly M. avium complex (MAC). CHARACTERISTICS OF 65 PATIENTS WITH MYCOBACTERIUM ABSCESSUS LUNG DISEASE WHO RECEIVED COMBINATION ANTIBIOTIC THERAPY FOR MORE THAN 12 MONTHS. Neutropenia and thrombocytopenia associated with cefoxitin developed in 33 (51%) and 4 (6%) patients, respectively. Sputum relapse was defined as two consecutive positive cultures after sputum conversion (18). Park S, Kim S, Park EM, Kim H, Kwon OJ, Chang CL, Lew WJ, Park YK, Koh WJ. 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. These results suggest that accurate species identification and in vitro clarithromycin susceptibility testing are important for the treatment of lung disease caused by M. abscessus group and treatment outcomes may be different depending on the precise species obtained. Continued global collaboration to better study these increasingly common pulmonary infections are now a necessity if we are to build on the promising findings of this study. This regimen continued for at least 12 months after sputum culture conversion. Treatment outcomes in patients with. Third, bacterial genotyping was not performed in nine patients who became culture positive again after initial sputum conversion. Drug-induced hepatotoxicity (aspartate aminotransferase or alanine aminotransferase levels ≥ 120 IU/L) occurred in 10 (15%) patients. Mycobacterium abscessus is often resistant to multiple an-timicrobial drugs, and data supporting effective drugs or dosing regimens are limited. We continue to use cefoxitin in the initial 4-week treatment period because of high in vitro susceptibility of M. abscessus isolates to cefoxitin and low reproducibility of susceptibility results for imipenem (1, 2). Importantly, they were able to show that the use of imipenem was associated with treatment success in MAB-PD overall (adjusted odds ratio 2.65, 95% CI 1.36–5.10), and for M. abscessus subsp. Diagnosis and treatment of nontuberculous mycobacterial pulmonary diseases: a Korean perspective. Residual bias, and the dangers of multiple testing in small cohorts, mean that one must still interpret these findings with a degree of caution. Infections with Mycobacterium abscessus can often cause serious symptoms. Mycobacterium abscessus (M. abscessus) is the most common strain of non-tuberculous mycobacteria (NTM). Cremades R, Santos A, Rodriguez JC, Garcia-Pachon E, Ruiz M, Royo G. Park IN, Hong SB, Oh YM, Kim MN, Lim CM, Lee SD, Koh Y, Kim WS, Kim DS, Kim WD. The decision to start antibiotic therapy is made by weighing the anticipated benefits and risks. Duarte RS, Lourenco MC, Fonseca Lde S, Leao SC, Amorim Ede L, Rocha IL, Coelho FS, Viana-Niero C, Gomes KM, da Silva MG, Wallace RJ Jr, Zhang Y, Brown BA, Dawson D, Murphy DT, Wilson R, Griffith DE. Koh WJ, Kwon OJ, Jeon K, Kim TS, Lee KS, Park YK, Bai GH. Published by John Wiley & Sons Ltd. The combination of clarithromycin and linezolid exhibits good in vitro activity against M. abscessus isolates (25, 29). In conclusion, a standardized combination therapy of antibiotics, which includes a clarithromycin-containing drug regimen, along with an initial 4-week course of cefoxitin and amikacin, is moderately effective in treating M. abscessus lung disease. Factors related to response to intermittent treatment of. An analysis of 154 patients. Treatment regimens cannot be optimized solely on the basis of retrospective studies with limited follow-up data; prospective clinical trials would be the proper approach. European Respiratory Society442 Glossop RoadSheffield S10 2PXUnited KingdomTel: +44 114 2672860Email: journals@ersnet.org, Print ISSN:  0903-1936 Follow-up HRCT scans were performed at a median 12.2 months (IQR, 11.9–12.5 mo) after the start of antibiotic therapy. M. abscessus is resistant to many antibiotics and thus is very difficult to treat. High prevalence of antimicrobial resistance in rapidly growing mycobacteria in Taiwan. Continuous variables were analyzed using a Mann-Whitney U test. Repeat positive cultures in. In vitro susceptibility test results to imipenem were available in 42 M. abscessus isolates. Leukopenia (white blood cell counts < 3,000/μl) and thrombocytopenia (platelet counts < 100,000/μl) developed in 33 (51%) and 4 (6%) patients, respectively. Antimicrobial susceptibility testing was performed at the Korean Institute of Tuberculosis. Chan ED, Kaminska AM, Gill W, Chmura K, Feldman NE, Bai X, Floyd CM, Fulton KE, Huitt GA, Strand MJ. Furthermore, both sputum conversion rates and relapse rates were significantly associated with clarithromycin resistance in this study. Wayne, PA: NCCLS. The authors thank Ms. Shinok Kim of the Korean Institute of Tuberculosis and Ms. Eun Mi Park of Samsung Medical Center for their assistance and technical support. Out of 65 patients, 41 (63%) patients completed the treatment.

The lack of a representative and standardized model of chronic infection in mice has limited steps forward in the field of MA pulmonary infection. aureus, Haemophilus influenzae, Pseudomonas aeruginosa, Strep. The present study has several limitations. Griffith DE, Girard WM, Wallace RJ Jr. Clinical features of pulmonary disease caused by rapidly growing mycobacteria. Mycobacterium abscessus complex (MABC) is one of the predominant pathogens capable of a wide spectrum of infections, with 50% of infections involving the lungs. 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). 1A ). The recent demonstration that bacteriophage therapy may offer an alternative treatment approach is one such direction [10], but others may include a better-defined role for improved mucociliary clearance, to help augment antibiotic therapy in MAB-PD, for example. Initial and follow-up HRCT scans were available for all patients, and these images were reviewed by two of the authors (K. Jeon and W-J. Mycobacterium abscessus is a prominent cause of pulmonary infection in immunosuppressed patients and those with cystic fibrosis. Thus, we are not sure whether the recurrence was due to relapse with the original strain or reinfection with a genetically different strain (40, 41). Common symptoms of NTM are chronic, dry cough, and shortness of breath. Isolates are usually susceptible only in vitro to the parenteral agents amikacin, cefoxitin, and imipenem, and to oral macrolides (clarithromycin and azithromycin) (1, 2 The incidence of β-lactam antibiotic-induced neutropenia increases when parenteral treatment is used in higher doses and extends beyond 2 weeks (19, 20). Additional detail on the method is provided in an online data supplement. ): M. abscessus subsp. Adekambi T, Berger P, Raoult D, Drancourt M. Kim HY, Kook Y, Yun YJ, Park CG, Lee NY, Shim TS, Kim BJ, Kook YH. The initial sputum conversion rate was 72% (47/65), and the median time until sputum conversion was 1 month (IQR, 1–1 mo). Koh WJ, Kwon OJ, Lee KS. Three patients were able to continue antibiotic therapy after reduction of the clarithromycin dosage (500 mg/d). Despite much welcome progress over the past decade in the field of chronic respiratory infections and bronchiectasis [1], treatment of pulmonary disease caused by infections with nontuberculous mycobacteria (NTM-PD) remains an area of significant, and increasing, challenge [2, 3]. The optimal therapeutic regimen and duration of treatment for M. abscessus lung disease has not been established. A better understanding of the most effective drug combinations in the treatment of MAB-PD is therefore critical if we are to offer patients a less nihilistic treatment pathway. Baseline characteristics of the patients are summarized in Table 2. Chronic lung disease as a result of Mycobacterium abscessus is an emerging infection in the United States. Additional detail on the method is provided in the online supplement. 1 Servicio de Microbiología y Parasitología, Hospital Universitario de la Princesa, Instituto de Investigación Sanitaria Princesa. Wallace RJ Jr, Brown-Elliott BA, Ward SC, Crist CJ, Mann LB, Wilson RW. A diagnosis in these cases was established via culture from bronchial washing or bronchoalveolar lavage. The most common are Mycobacterium avium complex or MAC. A multiple logistic regression model revealed that resistance to clarithromycin was independently associated with failure to conversion or relapse (odds ratio, 0.03; 95% CI, 0.01–0.32; P = 0.004) (Table 6). Pulmonary Mycobacterium abscessus: can we identify the road to improved outcomes. In recent years, Mycobacterium massiliense and Mycobacterium bolletii have been newly identified within the M. abscessus group (35, 36). But perhaps more importantly, it shows that if nihilism is no longer the right answer, then we must also be better at framing new questions in the search for a roadmap to better therapies for our patients with MAB-PD (and indeed NTM-PD more broadly). We retrospectively reviewed the medical records of all patients with M. abscessus lung disease at the Samsung Medical Center (a 1,250-bed referral hospital in Seoul, South Korea) between January 2000 and December 2007. NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. Koh). 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. Olaison L, Belin L, Hogevik H, Alestig K. Incidence of β-lactam-induced delayed hypersensitivity and neutropenia during treatment of infective endocarditis. Objectives: To assess the efficacy of a standardized combination antibiotic therapy for the treatment of M. abscessus lung disease. Some M. abscessus isolates are susceptible to linezolid, which is an oxazolidinone that is available as an oral drug (27, 28). The rate of infected patients is rapidly growing, and so is the proportion of Myco Ab patients within the NTM community. Diagnosis and treatment of infections caused by rapidly growing mycobacteria. Mycobacterium abscessus (M. abscessus) is a species complex with three distinct subtypes, known to cause infection predominantly in the lungs, especially among those with pre-existing lung conditions such as cystic fibrosis (Bryant, 2016). Has anyone ever been cured from this? Thomson RM, Yew WW. If the sputum samples are examined more frequently, we might find more frequent relapses and earlier ones. COMPARISON OF THE CLINICAL AND RADIOGRAPHIC CHARACTERISTICS OF PATIENTS WITH MYCOBACTERIUM ABSCESSUS LUNG DISEASE WHO RECEIVED ANTIBIOTIC THERAPY WITH THOSE WHO DID NOT RECEIVE ANTIBIOTIC THERAPY. 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. Three (5%) patients, who presented with the upper lobe cavitary form of M. abscessus lung disease had complications of chronic necrotizing pulmonary aspergillosis. intracellulare, and M. chimaera. Measurements and Main Results: Treatment response rates were 83% for symptoms and 74% for high-resolution computed tomography. massiliense, where treatment success was higher, in 56.7% of cases, there was not this apparent association of treatment success with antibiotic choice, possibly because the better outcomes masked observable treatment effect. 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. None of the examined isolates was susceptible to doxycycline (Table 3). Mycobacterium abscessus complex (MABSC) is a group of rapidly growing, multidrug-resistant, nontuberculous mycobacteria (NTM) species that are common soil and water contaminants. After discussing this information with the patients, we implemented an observation period of at least 6 to 12 months without antibiotic treatment. Optimal therapeutic regimens have not been established for M. abscessus lung disease. TABLE 6. abcessus puede causar enfermedad crónica pulmonar, infeccón de heridas postraumáticas, enfermedad cutánea diseminada principalmente en pacientes inmunodeprimidos. Thank you for your interest in spreading the word on European Respiratory Society . In South Korea, M. abscessus is the second most common pathogen responsible for lung disease caused by nontuberculous mycobacteria (NTM), after Mycobacterium avium-intracellulare complex (9, 10). The patients were treated over an 8-year period at a tertiary referral hospital in South Korea. massiliense and M. abscessus subsp. Of 86 (46%) patients who initiated combination antibiotic therapy, 21 patients were excluded because they had received antibiotic therapy for less than 12 months at the time of analysis. In contrast to clarithromycin, no such relationship was found for amikacin, cefoxitin, ciprofloxacin, or doxycycline in this study. NTM are found in the soil, air, and water, so you can get an infection from swimming, gardening, or breathing air with NTM. However, the patients did not receive the currently recommended combination of antibiotics, which includes newer macrolides such as clarithromycin. 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. pneumoniae, Burkholderia cepacia, and sometimes mycoses or mycobacteria. Of those, Mycobacterium abscessus appears in 16 to 68 percent of cases. 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). Mycobacterium abscessus [mī–kō–bak–tair–ee–yum ab–ses–sus] (also called M. abscessus) is a bacterium distantly related to the ones that cause tuberculosis and Hansen’s Disease (Leprosy). 1. *Low off-scale MICs were converted to the next-lowest concentration. During this period, 188 patients were newly diagnosed with M. abscessus lung disease. If an adverse reaction associated with cefoxitin occurred, imipenem (750 mg, three times a day) (3) was substituted for cefoxitin. However, when challenged with a high‐dose aerosol (HDA), … Nontuberculous mycobacterial lung disease is caused by infection with specific bacterial germs known as mycobacteria. In addition, sputum relapse after initial negative conversion was higher in patients infected with clarithromycin-resistant isolates (60%, 3/5) compared with those infected with clarithromycin-susceptible or intermediate isolates (16%, 4/25). The optimal therapeutic regimen and duration of treatment for Mycobacterium abscessus lung disease is not well established. 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). Two patients died due to disease progression at 18 and 30 months, respectively. This site uses cookies. The other 18 (28%) patients, including 2 patients who died of disease progression, failed to achieve sputum conversion. 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. Online ISSN: 1399-3003, Copyright © 2021 by the European Respiratory Society, Dept of Respiratory Medicine, Ninewells Hospital and Medical School, Dundee, UK. 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. The effect of parenteral tigecycline, a drug increasingly used in the treatment of MAB-PD in the intravenous induction phase, could not be assessed as it was not used frequently in the patient level data analysed. Thus, further studies are required to evaluate active combinations of oral antibiotics and determine their clinical importance. Olaison L, Alestig K. A prospective study of neutropenia induced by high doses of β-lactam antibiotics. Second, the number of sputum specimens collected over time was relatively low. TREATMENT RESPONSES OF 65 PATIENTS WITH MYCOBACTERIUM ABSCESSUS LUNG DISEASE. Drug susceptibility tests were performed on M. abscessus isolates recovered from 45 patients as described above. Imipenem displayed in vitro activity against a moderate number of isolates (48%, 20/42). MINIMUM INHIBITORY CONCENTRATIONS BREAKPOINTS AND IN VITRO SUSCEPTIBILITY OF MYCOBACTERIUM ABSCESSUS (N = 45). The remaining 15 patients continued antibiotic therapy until the end of December 2008 (median duration of treatment, 21.0 mo; IQR, 17.9–35.2 mo). Clinicians have the choice between personalized treatment regimens and standardized treatment regimens. Yamazaki Y, Kubo K, Takamizawa A, Yamamoto H, Honda T, Sone S. Markers indicating deterioration of pulmonary, Adekambi T, Reynaud-Gaubert M, Greub G, Gevaudan MJ, La Scola B, Raoult D, Drancourt M. Amoebal coculture of “. Mycobacterium abscessus complex is the most important source of pulmonary infections caused by rapidly growing mycobacteria in patients with chronic lung diseases, such as bronchiectasis and cystic fibrosis [ 3, 4 ]. *At the time of antibiotic therapy initiation. 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. Pulmonary TB and NTM lung disease: comparison of characteristics in patients with AFB smear-positive sputum. 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). In the study, researchers reported the case of an 8-year-old girl who was treated for an Mycobacterium abscessus infection and improved her bronchiectasis. Conflict of interest: M. Wilkie has nothing to disclose. Therefore, further follow-up data are essential. Diagnostic standards and classification of tuberculosis in adults and children. Fifty-seven (88%) patients had a positive acid-fast bacilli smear. 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. Four patients completely discontinued antibiotic therapy because of severe gastrointestinal symptoms after a median period of 15 months (IQR, 14.5–15.0 mo). Negative conversion of sputum was achieved and maintained for more than 12 months in 58% (38/65) of patients. Of the nontuberculous mycobacteria (NTMs) causing lung disease, members of the Mycobacterium abscessus complex (MABc) present a formidable obstacle to successful management. Mycobacterium abscessus. 2 When the disease was clearly recognized as being progressive, the patients received a standardized combination antibiotic therapy after hospitalization. They demonstrated that overall treatment success for MAB-PD was 45.6% (95% CI 26.7–64.4). These germs are commonly found throughout the environment.
