pulmonary mycobacterial infection treatment

No significant differences were found in terms of death, cure or recurrence between the two groups. In addition to microbiologic assessments, clinical and radiographic response to therapy should be used to determine if the patient is responding to therapy. The relative and absolute effect estimates and 95% CIs for each outcome (Table E3.4) and discussion of value preferences, feasibility, cost, acceptability, and health inequality (Table E4.4) can be found in the supplement. The relative and absolute effect estimates and 95% CIs for each outcome (Table E3.11) and discussion of value preferences, feasibility, cost, acceptability, and health inequality (Table E4.11) can be found in the supplement. The most commonly reported medications were IV amikacin (n = 22, 65%) and azithromycin (n = 24, 71%). Intermittent dosing of amikacin seemed to cause fewer side effects than daily dosing (42% vs. 77%, respectively). Regardless of the reasons for the increase, it is clear that healthcare providers will be encountering these patients increasingly frequently in the coming years. The committee was concerned about several aspects of these two studies including, (a) small sample size, (b) underdosing of the macrolide, (c) populations not representative of nodular bronchiectatic MAC pulmonary disease patients encountered frequently in clinical practice, (d) the use of gatifloxacin which is not approved for use or no longer marketed in many countries worldwide, and (e) the high overall mortality seen in one study [131], which raised questions about the validity of the study. Two randomized controlled studies in patients with M. xenopi pulmonary disease were conducted by the British Thoracic Society [36, 119, 131]. Phage therapy is a promising afresh therapy, which uses viruses to lyse bacteria responsible for the infection. The Infectious Diseases Society of America Emerging Infections Network: bridging the gap between clinical infectious diseases and public health. Rifampicin resistance (MIC > 2 µg/mL) is rare but can occur in isolates from patients with significant rifamycin exposures and failure of treatment with a rifamycin containing regimen [15]. Novosad SA, Beekmann SE, Polgreen PM, et al. A case series suggested that intermittent ethambutol administration was less often associated with ethambutol-related ocular toxicity than daily ethambutol administration [165]. Sputum culture conversion to negative was observed in 6 of the 27 patients (22%) who received treatment for <12 months, compared with 154 of 180 (86%) of patients who completed at least 12 months of therapy (P < .001). In patients with M. xenopi pulmonary disease, we suggest a daily regimen that includes at least three drugs: rifampicin, ethambutol, and either a macrolide and/or a fluoroquinolone (e.g., moxifloxacin) (conditional recommendation, very low certainty in estimates of effect). Macrolides possess potent activity against M. abscessus as well as immunomodulatory effects. bolletii have an erythromycin resistance methylase (erm) gene, named erm(41), that results in inducible resistance to macrolides [93]. Because sputum conversion at four months of rifampicin-based regimens is usually observed [29–31], expert consultation should be obtained if cultures fail to convert to negative by that time. In patients with noncavitary nodular/bronchiectatic M. kansasii pulmonary disease treated with a rifampicin, ethambutol, and macrolide regimen, we suggest either daily or three times weekly treatment (conditional recommendation, very low certainty in estimates of effect). The relative and absolute effect estimates and 95% CIs for each outcome (Table E3.13) and discussion of value preferences, feasibility, cost, acceptability, and health inequality (Table E4.13) can be found in the supplement. Not surprisingly, there were many gaps and needs identified related to the treatment of NTM pulmonary disease. Bronchoscopy is performed only in patients suspected of having NTM pulmonary disease from whom sputum specimens cannot be obtained spontaneously or through induction. Remarks: Given the usual disease severity of M. abscessus pulmonary disease, the variable and limited in vitro drug susceptibility of these organisms, the potential for the emergence of drug resistance, and the potential for more rapid progression of M. abscessus pulmonary disease, the panel members suggest using a regimen consisting of three or more active drugs. The incidence and prevalence of NTM pulmonary disease are increasing in many areas of the world with rates particularly high in older individuals and those with underlying bronchiectasis [44–48]. For patients with NB MAC lung disease, the priorities are typically to treat the underlying bronchiectasis and determine the course and impact of the MAC infection over time. One hundred forty-six patients with MAC pulmonary disease (both nodular/bronchiectatic and cavitary disease) were randomized to receive clarithromycin, ethambutol, and a rifamycin daily with (73) or without (73) streptomycin (15 mg/kg 3 times per week during the initial 3 months of therapy). This recommendation is based on expert opinion and data from murine models of M. xenopi infection, wherein microbiologic benefit was observed in mice treated with amikacin [191, 192]. Therapy with antimicrobial agents continued during and after the surgery, and the activity of these agents varied with regard to the study and the species involved (eg, clarithromycin was given in recent studies but not in the older ones). A critically important finding from the available studies is the lack of development of macrolide resistance with intermittent therapy [22, 23]. Clinically significant MAC pulmonary disease is unlikely in patients who have a single positive sputum culture during the initial evaluation [5–7] but can be as high as 98% in those with ≥2 positive cultures [5]. For patients with cavitary or advanced/severe bronchiectatic or macrolide-resistant MAC pulmonary disease, we suggest that parenteral amikacin or streptomycin be included in the initial treatment regimen. Recent studies have reported poor treatment outcomes associated with macrolide resistance due to either mutational or inducible resistance related to the presence of a functional erm(41) gene in M. abscessus subsp. Reported side effects in these series ranged from 8 to 38% and included hoarseness, throat irritation, bitter taste, and thrush. IV agents were commonly associated with side effects that often required dosage adjustment or discontinuation. In MAC pulmonary disease, retrospective case series [83, 84, 112, 117, 118] have also shown that in vitro resistance to clarithromycin was associated with worse outcomes than susceptibility to clarithromycin, and a randomized trial found no association between in vitro susceptibility to either rifampicin or ethambutol and failure/relapse [119]. This case features a patient with non-TB mycobacterial infection who's receiving anti-TNF to treat rheumatoid arthritis In the absence of data to support a shorter or longer treatment course for M. abscessus pulmonary disease, the panel members suggest that expert consultation be obtained prior to initiation of therapy in order to assist with design of the regimen and determine whether a shorter or longer treatment regimen should be used. Significant adverse events were reported in one study (14.7%), leading to discontinuation of the parenteral agent in 9.5% [28]. Concurrent conditions included cystic fibrosis (n = 9, 14%), cancer (n = 7, 11%), and chronic obstructive pulmonary disease (n = 6, 9%). For specific pathogens (M. avium complex, M. kansasii, M. xenopi, and M. abscessus), the PICO questions are organized by the drugs to be included in the regimen, frequency of administration, and duration of therapy. Some of the reported relapses may actually be exogenous reinfections, as suggested by the long periods between treatment completion and recurrence [27, 173]. Similarly, there are no data to support the use of isoniazid on a three times weekly basis in patients with M. kansasii pulmonary disease. Similarly for extrapulmonary disease, macrolide-based treatment regimens based on susceptibility testing results are recommended (1,2). Other important NTM causing pulmonary disease are M. kansasii and M. xenopi. Major symptoms such as severe fatigue with marked decrease in quality of life can also be major factors in starting therapy. MAC includes two closely related species, Mycobacterium avium and Mycobacterium intracellulare, and may also be referred to as MAI.MAC is one of a large group of nontuberculous mycobacteria (NTM), and the most common cause of NTM lung disease in the … The desirable anticipated effects were estimated to be moderate. Treatment regimens are based on the identity of the isolated species, drug sensitivity testing (for some agents) and the severity of disease. A total of 65 cases were reported from 16 states; patient mean age was 53.6 years. ), and a representative from an NTM nonprofit organization the goal of which is patient support, education, and research in NTM (P.L.). In general, regimens of three oral agents, rifampicin and ethambutol, and either isoniazid or a macrolide, achieve high rates of sustained culture conversion and treatment success in the treatment of M. kansasii pulmonary disease. Twenty-eight (82%) patients required a change in therapy (because of side effects, lack of effectiveness, or need for suppressive regimen); 3 underwent surgical therapy, and 12 stopped therapy (median duration 12 months, interquartile range [IQR] 9–18 months). The pathogenicity of NTM varies significantly from organisms like M. gordonae, which rarely cause disease in humans, to M. kansasii, which should usually be considered pathogenic [8]. In patients with rifampicin-resistant M. kansasii or intolerance to one of the first-line antibiotics we suggest a fluoroquinolone (e.g., moxifloxacin) be used as part of a second-line regimen. No significant differences were found between the two regimens in term of death, cure, recurrence or adverse effects. Remarks: A priority in MAC pulmonary disease therapy is preventing the development of macrolide resistance. The relative and absolute effect estimates and 95% CIs for each outcome (Table E3.18) and discussion of value preferences, feasibility, cost, acceptability, and health inequality (Table E4.18) can be found in the supplement. For the remainder, subculture on solid media until the occurrence of visual growth is needed to obtain good MALDI-TOF results [79]. A panel of experts was carefully selected by leading international respiratory medicine and infectious diseases societies (ATS, ERS, ESCMID, IDSA) and included specialists in pulmonary medicine, infectious diseases and clinical microbiology, laboratory medicine, and patient advocacy. In some instances, “watchful waiting” may be the preferred course of action. The optimal duration of therapy for MAC pulmonary disease is currently not known. The incidence of adverse events leading to the discontinuation of treatment was 37.2% and 26.6% for the three-drug and the two-drug regimens, respectively. From this perspective, a multidrug regimen that utilizes a macrolide or fluoroquinolone would be likely more active. Only one randomized clinical trial has been published that compared ciprofloxacin with clarithromycin when added to rifampicin and ethambutol in patients with M. xenopi pulmonary disease [131]. Strength of the recommendations was based upon the confidence in the estimates of effect, the outcomes studied and associated importance to patients, the desirable and undesirable consequences of treatment, the cost of treatment, the implications of treatment on health equity, the feasibility of treatment, and the acceptability of treatment to important stakeholders. Many of the research priorities relate to the need for new drugs, treatment regimens, shorter regimens, and better tolerated regimens. Reports evaluating the use of inhaled amikacin as part of a multidrug regimen for NTM pulmonary disease, including patients with MAC pulmonary disease, have primarily targeted patients with treatment refractory disease. There are two randomized studies that compared a two-drug regimen with a three-drug regimen [21, 119], but only one of these studies included a macrolide-containing regimen [21]. Barring compelling evidence to the contrary, M xenopi patients should be treated aggressively given the high mortality of the disease [34–36]. Diagnosis of NTM pulmonary disease requires the synthesis of clinical, radiographic, and microbiology data. XVII: In patients with M. xenopi pulmonary disease, should parenteral amikacin or streptomycin be included in the treatment regimen? There was no evidence identified for costs, which were estimated as moderate with regard to the duration of the disease. The current guideline also recommends use of these criteria to classify patients as having NTM pulmonary disease (Table 2). This observational, retrospective study included 30 patients with M. abscessus pulmonary disease who met the diagnostic criteria defined in the 2007 Guideline. Treatment success of M. kansasii pulmonary disease with a rifamycin-based drug regimen is usually excellent but the optimal choice of companion drugs is not clear.
