Effect of azithromycin on bronchiolitis obliterans syndrome in posttransplant recipients: A systematic review and meta-analysis.
Bronchiolitis obliterans syndrome (BOS) is a devastating complication that occurs after transplantation. Although azithromycin is currently used for the treatment of BOS, the evidence is sparse and controversial. The aim of this meta-analysis is to evaluate the effects of azithromycin on forced expiratory volume in 1 second (FEV1) and patient's survival.. PubMed, Embase, Cochrane library, Web of Science databases, and the ClinicalTrials.gov registry were systematically searched from inception until December 2020 for relevant original research articles. Random-effects models were used to calculate pooled-effect estimates.. Searches identified 15 eligible studies involving 694 participants. For FEV1 (L), there was a significant increase after short-term (≤12 weeks; P = .00) and mid-term (12-24 weeks; P = .01) administration of azithromycin. For FEV1 (%) compared to baseline, there was a significant increase after short-term (≤12 weeks) administration of azithromycin (P = .02), while there were no statistically significant differences in the medium and long term. When pooled FEV1% was predicted, it exhibited a similar trend to FEV1 (%) compared to baseline. In addition, we discovered that azithromycin reduced the risk of death (hazard ratio = 0.26; 95% confidence interval = 0.17 to 0.40; P = .00) in patients with BOS post-lung transplantation.. Azithromycin therapy is both effective and safe for lung function improvement in patients with posttransplant BOS after the short- and medium-term administration. Additionally, it has been demonstrated a significant survival benefit among patients with BOS post-lung transplant. Higher quality randomized controlled trials and more extensive prospective cohort studies are needed to confirm the effect of azithromycin on patients with posttransplant BOS.

High-Resolution CT Findings of Obstructive and Restrictive Phenotypes of Chronic Lung Allograft Dysfunction: More Than Just Bronchiolitis Obliterans Syndrome.
The purpose of this article is to review the high-resolution CT characteristics of individual obstructive and restrictive chronic lung allograft dysfunction (CLAD) phenotypes to aid in making accurate diagnoses and guiding treatment.. Long-term survival and function after lung transplant are considerably worse compared with after other organ transplants. CLAD is implicated as a major limiting factor for long-term graft viability. Historically thought to be a single entity, bronchiolitis obliterans syndrome, CLAD is actually a heterogeneous group of disorders with distinct subtypes.

Infection in severe asthma exacerbations and critical asthma syndrome.
In chronic persistent asthma and severe acute exacerbations of bronchial asthma, infectious agents are the predominant triggers that drive disease and airway pathobiology. In acute exacerbations of bronchial asthma (AEBA) including near fatal and fatal asthma, viral agents, particularly human rhinovirus-C, respiratory syncytial virus and influenza A appear to be the more prevalent and recurring threats. Both viral, and to a lesser extent bacterial agents, can play a role, and co-infection may also be present and worsen prognosis in hospitalized patients, placing a portion at risk for critical asthma syndrome. During severe acute exacerbations, infectious agents must be treated empirically, but the initial treatment regimens can vary and viral coverage may also vary based on seasonality and patient age. Early treatment with ceftriaxone and azithromycin, along with oseltamivir in winter months, should be initiated with all cases of severe exacerbations where infection is suspected, and definitely in critical asthma syndrome until infection is excluded by appropriate diagnostic testing. In this manuscript we will outline the impact of the major viral agents on severe asthma including the data from the 2009 H1N1 influenza pandemic. The role of bacterial infections in acute exacerbations of asthma will also be reviewed as well as the benefit of empiric antibiotics and the role of macrolides in both acute and chronic asthma.

Azithromycin improves lung function in patients with post-lung transplant bronchiolitis obliterans syndrome: a meta-analysis.
Azithromycin has been shown to reverse or halt the decline of forced expiratory volume in one s (FEV1) in patients with bronchiolitis obliterans (BOS) syndrome following lung transplant. The overall effect of azithromycin on the absolute values of FEV1 has not been compared between reported studies. We studied the effects of azithromycin on lung function in patients with post-lung transplant BOS syndrome.. A meta-analysis was performed using studies identified following an extensive database search. To be included, studies were published in English or French and explicitly reported percentage change in FEV1 or hazard ratios.. A total of 10 studies were included in this review. One hundred and forty patients were evaluated after treatment with azithromycin for an average follow-up period of seven months. The mean percentage increase in FEV1 was 8.8 (CI 5.1-12.47) p < 0.001. The pooled hazard ratio was 0.25 (CI 0.06-0.56) p = 0.041 for a mean follow-up period of 2.9 yr.. This study demonstrated a significant improvement in lung function in patients with BOS syndrome following lung transplant after seven months of treatment. It remains uncertain whether this improvement stays after seven months. We also found that patients on azithromycin were less likely to die from BOS syndrome compared with patients who were not on azithromycin.

[Update on SENLAT syndrome: scalp eschar and neck lymph adenopathy after a tick bite].
SENLAT syndrome, also known as TIBOLA/DEBONEL, is an emerging disease in France. The major symptoms are necrotic eschar on the scalp associated with painful cervical lymphadenopathy. It occurs mainly in women and children during the cold seasons after a bite by a Dermacentor tick, responsible for transmitting Rickettsia slovaca or Rickettsia raoultii. Cutaneous swabs are safe, easy and reliable tools that should be used routinely by physicians to confirm diagnosis. In this particular disease, they should be preferred to serology, which is less sensitive. Doxycycline is the antibiotic of choice for this syndrome.

Chronic lung allograft dysfunction after lung transplantation: the moving target.
Chronic lung allograft dysfunction is a major challenge in long-term management of lung transplant recipients. Both alloimmune-dependent factors (rejection) and alloimmune-independent factors contribute to the development of chronic lung allograft dysfunction. Thus, use of the term "chronic rejection" tends to be intentionally avoided among specialists in the field, although "chronic rejection" is still an acceptable lay word understood by many patients. Several different phenotypes have been identified in chronic lung allograft dysfunction, including restrictive allograft syndrome, neutrophilic reversible allograft dysfunction, and fibrous bronchiolitis obliterans syndrome. Restrictive allograft syndrome is characterized by restrictive physiology and peripheral foci of inflammation and fibrosis, which contrasts the obstructive physiology and pathological foci in small airways in conventional bronchiolitis obliterans syndrome. Among patients with bronchiolitis obliterans syndrome, there is a subpopulation that responds relatively well to azithromycin. Because these patients show airway neutrophilia, this subtype of chronic lung allograft dysfunction was named neutrophilic reversible allograft dysfunction. Conversely, patients with bronchiolitis obliterans syndrome unresponsive to azithromycin show airway fibrosis with less inflammation (fibrous bronchiolitis obliterans syndrome). In general, restrictive allograft syndrome shows poorer survival than does bronchiolitis obliterans syndrome, and early-onset bronchiolitis obliterans syndrome (within 2 years) shows a worse prognosis than does late-onset bronchiolitis obliterans syndrome. Until preventive and therapeutic options are refined, chronic lung allograft dysfunction will remain a major life-limiting factor. It has significant psychological, physical, social, and economic impacts. Early introduction of palliative care is another important strategy to improve patients' quality of life.

Lung transplantation: the role of azithromycin in the management of patients with bronchiolitis obliterans syndrome.
Bronchiolitis obliterans syndrome (BOS) is the leading cause of death in lung transplant recipients (LTR). BOS is thought to result from chronic immunologic/inflammatory insults leading to peri-bronchiolar leukocyte infiltration, with a subsequent exuberant tissue re-modelling and fibro-obliteration of the luminal space of the allograft airways. Diagnosis is based on functional criteria and severity is graded on the degree of Forced Expiratory Volume in 1 second (FEV1) impairment. Current strategies to improve pulmonary function once BOS is established have demonstrated little or no impact on disease progression and re-transplantation remains the only therapeutic option. Among the alternative treatments which have been attempted in the last few years, long-term azithromycin treatment seems to be the most promising therapeutic device for BOS treatment. Azithromycin is a macrolide antibiotic, endowed with a broad spectrum of anti-inflammatory/immunomodulatory activities. Long-term oral azithromycin therapy can significantly improve FEV1 in about 42% of patients with established BOS. Moreover, reduced neutrophilia, chemokine release and bacterial exacerbations have been demonstrated. These observations suggest that the drug can down-regulate pulmonary inflammation, even if the precise underlying mechanisms still need to be determined.

Is it bronchiolitis obliterans syndrome or is it chronic rejection: a reappraisal?
Chronic rejection (obliterative bronchiolitis) is the single most important cause of chronic allograft dysfunction and late mortality after lung transplantation. As this condition is difficult to prove using biopsy specimens, a clinical term, bronchiolitis obliterans syndrome (BOS) has been in use for >10 yrs to describe the progressive decrease of pulmonary function. However, before diagnosing a patient as having BOS, based on a sustained and progressive decrease in forced expiratory volume in one second and/or forced mid-expiratory flow between 25-75% of forced vital capacity, different confounding factors have to be eliminated. Treatment of BOS mainly consists of an increase or a change in the immunosuppressive drug regimen, which may lead to more pronounced infectious complications. Recently, two new options have become available to treat patients with BOS, treatment of gastro-oesophageal reflux and azithromycin. In the present paper, the authors give an overview of the current data on these two modalities, which may lead to a restoration of the pulmonary function in some of the patients, illustrating once more the fact that bronchitis obliterans syndrome is not always a manifestation of chronic rejection.

Long-term effect of azithromycin in bronchiolitis obliterans syndrome.
Azithromycin stabilises and improves lung function forced expiratory volume in one second (FEV. Eligible patients recruited for the initial randomised placebo-controlled trial received open-label azithromycin after 3 months and were followed up until 6 years after inclusion (n=45) to assess FEV. Long-term treatment with azithromycin slows down the progression of BOS, although the effect of TLI may affect the observed attenuation of FEV Topics: Adult; Azithromycin; Bronchiolitis Obliterans; Disease Progression; Double-Blind Method; Female; Forced Expiratory Volume; Humans; Male; Middle Aged; Survival Rate; Syndrome; Time Factors; Treatment Outcome | 2019 |
Prophylactic Azithromycin Therapy After Lung Transplantation: Post hoc Analysis of a Randomized Controlled Trial.
Prophylactic azithromycin treatment has been demonstrated to improve freedom from bronchiolitis obliterans syndrome (BOS) 2 years after lung transplantation (LTx). In the current study, we re-evaluated the long-term effects of this prophylactic approach in view of the updated classification system for chronic lung allograft dysfunction (CLAD). A retrospective, intention-to-treat analysis of a randomized controlled trial comparing prophylactic treatment with placebo (n = 43) versus azithromycin (n = 40) after LTx was performed. Graft dysfunction (CLAD), graft loss (retransplantation, mortality), evolution of pulmonary function and functional exercise capacity were analyzed 7 years after inclusion of the last study subject. Following LTx, 22/43 (51%) patients of the placebo group and 11/40 (28%) patients of the azithromycin group ever developed CLAD (p = 0.043). CLAD-free survival was significantly longer in the azithromycin group (p = 0.024). No difference was present in proportion of obstructive versus restrictive CLAD between both groups. Graft loss was similar in both groups: 23/43 (53%) versus 16/40 (40%) patients (p = 0.27). Long-term pulmonary function and functional exercise capacity were significantly better in the azithromycin group (p < 0.05). Prophylactic azithromycin therapy reduces long-term CLAD prevalence and improves CLAD-free survival, pulmonary function, and functional exercise capacity after LTx.

A randomised controlled trial of azithromycin therapy in bronchiolitis obliterans syndrome (BOS) post lung transplantation.
We conducted a placebo-controlled trial of azithromycin therapy in bronchiolitis obliterans syndrome (BOS) post lung transplantation.. We compared azithromycin (250 mg alternate days, 12 weeks) with placebo. Primary outcome was FEV1 change at 12 weeks.. 48 patients were randomised; (25 azithromycin, 23 placebo). It was established, post randomisation that two did not have BOS. 46 patients were analysed as intention to treat (ITT) with 33 'Completers'. ITT analysis included placebo patients treated with open-label azithromycin after study withdrawal.. The ITT analysis (n=46, 177 observations) estimated mean difference in FEV1 between treatments (azithromycin minus placebo) was 0.035 L, with a 95% CI of -0.112 L to 0.182 L (p=0.6). Five withdrawals, who were identified at the end of the study as having been randomised to placebo (four with rapid loss in FEV1, one withdrawn consent) had received rescue open-label azithromycin, with improvement in subsequent FEV1 at 12 weeks. Study Completers showed an estimated mean difference in FEV1 between treatment groups (azithromycin minus placebo) of 0.278 L, with 95% CI for the mean difference: 0.170 L to 0.386 L (p=<0.001). Nine of 23 ITT patients in the azithromycin group had ≥10% gain in FEV1 from baseline. No patients in the placebo group had ≥10% gain in FEV1 from baseline while on placebo (p=0.002). Seven serious adverse events, three azithromycin, four in the placebo group, were deemed unrelated to study medication.. Azithromycin therapy improves FEV1 in patients with BOS and appears superior to placebo. This study strengthens evidence for clinical practice of initiating azithromycin therapy in BOS..

[Effect of Zhifei mixture combined western drugs on symptoms and signs of children with mycoplasma pneumonia].
To observe the effect of three Chinese medical formulae (Zhifei Mixture I , Zhfei Mixture II, and Zhifei Mixture II) on main and secondary symptoms and signs of children with Totally 70 mycoplasma pneumonia in treating three types of children mycoplasma pneumonia.. children with mycoplasma pneumonia were assigned to the control group (38 cases) and the treatment group (32 case). All patients were intravenously injected with Azithromycin and took Ambroxol Hydrochloride and Clenbuterol Hydrochloride Oral Solution. Those in the treatment group additionally took Zhifei Mixture I , Zhfei Mixture II, and Zhifei Mixture Ill by syndrome typing. Their main and secondary symptoms and signs were observed before and after treatment (main symptoms and signs covered fever, cough, abundant sputum, short breath, and anoxia; secondary symptoms and signs covered aversion to cold, heart rate, facial complexion, spirit, appetite, and sweating).. Seven patients were lost in this study. Compared with before treatment in the same group, scores for main and secondary symptoms and signs decreased in the treatment group (P <0.01). The therapeutic effect on fever and cough was obviously better in the control group (P <0.01). The main and secondary symptoms and signs were more obviously improved in the treatment group than in the control group (P <0.01). Commpared with the control group, scores for main and secondary symptoms and signs decreased more in the treatment group (P <0.01). Patients' main and secondary symptoms and signs were more obviously improved (P <0.05).. Zhifei Mixture combined Western drugs could significantly improve main and secondary symptoms and signs of mycoplasma pneumonia children patients. Its efficacy was superior to that of using Western medicine alone.

Effects of azithromycin in bronchiolitis obliterans syndrome after hematopoietic SCT--a randomized double-blinded placebo-controlled study.
Bronchiolitis obliterans syndrome (BOS) is an important complication after hematopoietic SCT (HSCT). Recent observations suggested that azithromycin might improve lung function in BOS after HSCT. We conducted a randomized double-blinded placebo-controlled study on azithromycin in patients with BOS after HSCT. The treatment group (n=10) received oral azithromycin 250 mg daily while the control group (n=12) received placebo daily for 12 weeks. Respiratory symptoms were assessed by the St George Respiratory Questionnaires and spirometry at baseline (drug commencement), 1, 2, 3 (drug cessation) and 4 months (1 month after drug cessation). There was no significant difference in the baseline demographic characteristics between the treatment and the control groups in age, gender, time from HSCT to BOS, time since diagnosis of BOS, chronic GVHD, baseline respiratory symptom scores and baseline forced expiratory volume in 1 s (FEV(1)). Throughout and after 3 months of treatment, there were no significant changes in respiratory symptom scores and FEV(1) measurements between the treatment and the control groups. In conclusion, there was no significant benefit of 3 months of oral azithromycin on the respiratory symptoms and lung function in patients with relatively late BOS after HSCT in this randomized placebo-controlled study.

Maintenance azithromycin therapy for bronchiolitis obliterans syndrome: results of a pilot study.
Bronchiolitis obliterans syndrome remains the leading cause of morbidity and mortality in the pulmonary transplant population. Previous studies show that macrolide antibiotics may be efficacious in the treatment of panbronchiolitis and cystic fibrosis. In the latter, azithromycin decreases the number of respiratory exacerbations, improves FEV1, and improves quality of life. We hypothesized that oral azithromycin therapy may improve lung function in patients with bronchiolitis obliterans syndrome. To test this hypothesis, we conducted an open-label pilot trial using maintenance azithromycin therapy in six lung transplant recipients (250 mg orally three times per week for a mean of 13.7 weeks). In this study, five of these six individuals demonstrated significant improvement in pulmonary function, as assessed by FEV1, as compared with their baseline values at the start of azithromycin therapy. The mean increase in the percentage of predicted FEV1 values in these individuals was 17.1% (p = 0.05). In addition, the absolute FEV1 increased by 0.50 L (range -0.18 to 1.36 L). These data suggest a potential role for maintenance macrolide therapy in the treatment of bronchiolitis obliterans syndrome in lung transplant recipients.

Effect of treatment for Chlamydia pneumoniae and Helicobacter pylori on markers of inflammation and cardiac events in patients with acute coronary syndromes: South Thames Trial of Antibiotics in Myocardial Infarction and Unstable Angina (STAMINA).
Infection with Helicobacter pylori and Chlamydia pneumoniae is associated with coronary heart disease. We conducted an intervention study using antibiotics against these bacteria in patients with acute coronary syndromes to determine whether antibiotics reduce inflammatory markers and adverse cardiac events.. Patients (n=325) admitted with acute myocardial infarction or unstable angina (acute coronary syndromes) were randomized to receive a 1-week course of 1 of 3 treatment regimens: (1) placebo; (2) amoxicillin (500 mg twice daily), metronidazole (400 mg twice daily), and omeprazole (20 mg twice daily); or (3) azithromycin (500 mg once daily), metronidazole (400 mg twice daily), and omeprazole (20 mg twice daily). Serum fibrinogen, white cell count, and high-sensitivity C-reactive protein were measured at study entry and at 1, 3, and 12 months during follow-up. Cardiac death and readmission with acute coronary syndrome were considered clinical end points. Patients were followed for 1 year. C-reactive protein levels were reduced (P=0.03) in unstable angina patients receiving amoxicillin, and fibrinogen was reduced in both patient groups receiving antibiotics (P=0.06). There were 17 cardiac deaths and 71 readmissions with acute coronary syndrome. No difference in frequency or timing of end points was observed between the 2 antibiotic groups. At 12 weeks, there was a 36% reduction in all end points in patients receiving antibiotics compared with placebo (P=0.02). This reduction persisted during the 1-year follow-up. Neither C pneumoniae nor H pylori antibody status was significantly related to response to treatment.. Antibiotic treatment significantly reduced adverse cardiac events in patients with acute coronary syndromes, but the effect was independent of H pylori or C pneumoniae seropositivity.

Duration of clinical symptoms in female patients with acute urethral syndrome caused by Chlamydia trachomatis treated with azithromycin or doxycycline.
One hundred fifty-one female patients with acute urethral syndrome caused by Chlamydia trachomatis were examined. First, patients were divided into two groups, those with clinical symptoms present < 3 weeks before the start of treatment, and those with clinical symptoms > or = 3 weeks prior to the beginning of therapy. Then patients were further divided into groups and randomized to receive azithromycin once daily in a single dose of 1.0 g or 500 mg once daily for 6 days, or to receive doxycycline 100 mg b.i.d. for 14 days or 100 mg b.i.d. for 7 days (8 study groups in all). Clinical and bacteriological efficacy was evaluated 3 weeks after the end of therapy. In the group of patients with disease symptoms lasting for 3 weeks or longer, the eradication and clinical cure rates were significantly higher after administration of azithromycin in a dose of 1x500 mg/6 days than after a single dose of 1.0 g (p<0.01), and after administration of doxycycline 2x100 mg/14 days than by using doxycycline 2x100 mg/7 days (p<0.05).

Azithromycin and doxycycline in the treatment of female patients with acute urethral syndrome caused by Ureaplasma urealyticum: significance of duration of clinical symptoms.
One hundred ninety-two female patients with acute urethral syndrome caused by Ureaplasma urealyticum were examined. First, patients were divided into two groups: those with clinical symptoms present for less than 3 weeks before the start of treatment and those with clinical symptoms 3 weeks or longer before the beginning of therapy. The patients were then further divided into groups and randomized to receive azithromycin once daily in a single dose of 1 g or 500 mg once daily for 6 days, or to receive doxycycline 100 mg b.i.d. for 14 days or 100 mg b.i.d. for 7 days (eight study groups in all). Clinical and bacteriological efficacy were evaluated 3 weeks after the end of therapy. In the group of patients with disease symptoms lasting for 3 weeks or longer, eradication and clinical cure rates were significantly higher after the administration of azithromycin at a dose of 1 x 500 mg/6 days than after a single dose of 1 g (p < 0.001).

Azithromycin for empirical treatment of the nongonococcal urethritis syndrome in men. A randomized double-blind study.
To evaluate the use of single-dose azithromycin for empirical treatment of nongonococcal urethritis.. Randomized, double-blind, multicenter trial comparing azithromycin vs doxycycline therapy, with a 2:1 randomization ratio. Patients were evaluated clinically and microbiologically for Chlamydia trachomatis and Ureaplasma urealyticum infection before therapy and at 2 and 5 weeks after study entry.. Eleven sexually transmitted disease clinics throughout the United States.. A total of 452 men aged 18 years or older with symptomatic nongonococcal urethritis of less than 14 days' duration.. Patients were treated with either 1.0 g of azithromycin as a single oral dose or 100 mg of doxycycline taken orally twice daily for 7 days.. Clinical resolution of symptoms and signs of nongonococcal urethritis, microbiological cure of C trachomatis and U urealyticum, and occurrence of adverse experiences.. Of the 452 patients enrolled, 248 in the azithromycin-treated group and 123 in the doxycycline-treated group were evaluable for clinical response. The two treatment groups were comparable in terms of age, weight, ethnic distribution, sexual preference, sexual activity, and history of prior nongonococcal urethritis or gonorrhea. Sixteen percent of the azithromycin group and 24% of the doxycycline group were culture positive for C trachomatis before therapy, while 38% and 28%, respectively, were culture positive for U urealyticum. The cumulative clinical cure rate was 81% (95% confidence interval [CI], 75% to 85%) in the azithromycin-treated group and 77% (95% CI, 69% to 84%) in the doxycycline-treated group. Clinical cure rates in the two groups were also comparable when patients were stratified by presence or absence of infection with C trachomatis or U urealyticum prior to therapy. Among those infected with C trachomatis, overall microbiological cure rates were 83% (95% CI, 65% to 94%) for azithromycin-treated patients (n = 30) and 90% (95% CI, 68% to 98%) for doxycycline-treated patients (n = 21). Among those infected with U urealyticum, overall microbiological cure rates were 45% (95% CI, 34% to 57%) for azithromycin-treated patients (n = 75) and 47% (95% CI, 30% to 65%) for doxycycline-treated patients (n = 32). Adverse reactions were generally mild to moderate and occurred in 23% of the azithromycin-treated group and 29% of the doxycycline-treated group.. For empirical treatment of the acute nongonococcal urethritis syndrome in men, a single oral dose of azithromycin was as effective as a standard 7-day course of doxycycline in achieving clinical cure. Further, clinical cure rates were comparable with either regimen, regardless of the presence or absence of Chlamydia or Ureaplasma infection.

Tropical diseases in the ICU: A syndromic approach to diagnosis and treatment.
Tropical infections form 20-30% of ICU admissions in tropical countries. Diarrheal diseases, malaria, dengue, typhoid, rickettsial diseases and leptospirosis are common causes of critical illness. Overlapping clinical features makes initial diagnosis challenging. A systematic approach involving (1) history of specific continent or country of travel, (2) exposure to specific environments (forests or farms, water sports, consumption of exotic foods), (3) incubation period, and (4) pattern of organ involvement and subtle differences in manifestations help in differential diagnosis and choice of initial empiric therapy. Fever, rash, hypotension, thrombocytopenia and mild derangement of liver function tests is seen in a majority of patients. Organ failure may lead to shock, respiratory distress, renal failure, hepatitis, coma, seizures, cardiac arrhythmias or hemorrhage. Diagnosis in some conditions is made by peripheral blood smear examination, antigen detection or detection of microbial nucleic acid by PCR. Tests that detect specific IgM antibody become positive only in the second week of illness. Initial therapy is often empiric; a combination of intravenous artesunate, ceftriaxone and either doxycycline or azithromycin would cover a majority of the treatable syndromes. Additional antiviral or antiprotozoal medications are required for some specific syndromes. Involving a physician specializing in tropical or travel medicine is helpful.

Azithromycin reverses airflow obstruction in established bronchiolitis obliterans syndrome.
A recent pilot study noted clinical benefit of macrolide therapy in the management of six lung transplant recipients with bronchiolitis obliterans syndrome (BOS), a condition previously regarded as irreversible.. To examine the effect of low-dose macrolides on lung function in lung allograft recipients with established BOS and to assess whether this benefit is sustained.. We retrospectively evaluated the effect of azithromycin (250 mg alternate days) on clinical status and lung function in 20 allograft recipients with established BOS, confirmed by decline in FEV(1) or FEF(25-75); consistent high-resolution computed tomography findings; and exclusion of acute rejection, infection, or anastomatic complications. Azithromycin was introduced at mean 82 months after transplantation. BOS staging at initiation of treatment was BOS 3 (10), BOS 2 (2), BOS 1 (6), and BOS0-p (2). All patients were on maintenance immunosuppression comprising cell-cycle inhibitor, oral corticosteroids, and calcineurin inhibitor.. There was a significant increase in FEV(1) of median 110 ml (range, -70 to 730 ml) between baseline and 3 months of azithromycin therapy (p = 0.002). This improvement was sustained beyond 3 months in the majority of patients, who had initially benefited from azithromycin (up to 11 months follow up).. This case series confirms the benefit of azithromycin in not only halting, but reversing the declining lung function seen in patients with BOS. This benefit appears to be maintained over time. Low-dose macrolides offer a new and exciting therapeutic strategy for the treatment of progressive BOS, and further clinical and translational mechanistic studies are required.
