Inhaled corticosteroids in COPD and the risk of serious pneumonia.

inhaled corticosteroids pneumonia

While residual confounding cannot be ruled out, the results are consistent with those from recent randomised trials. Side effects with these anti-inflammatory asthma inhalers are minimal. Highlights from this issue. Patients receiving ICS fluticasone propionate, whether as monotherapy or in combination with LABA had higher rate of physician reported pneumonia Thrush a yeast infection in the mouth and hoarseness may occur, although this is rare.

About half were prescribed the handheld, disposable corticosteroid inhalers, such as puffers, turbohalers, diskhalers and nebulizers, while the rest were not. Based on their established efficacy and adequate safety profile these medications are recommended in the treatment of the most prevalent chronic respiratory diseases such as asthma and COPD 9 , Immunomodulator treatment has been shown to help reduce the number of asthma attacks in people with moderate to severe allergic asthma whose symptoms are not controlled with inhaled steroids. Association of inhaled corticosteroid use with cataract extraction in elderly patients [published erratum appears in JAMA Dec 2; It affects more than 5 million adults and accounts for more than 1 million admissions each year in the United States 1 , 2. Didn't get the message? Combined salmeterol and fluticasone in the treatment of chronic obstructive pulmonary disease:

All doses of ICS were converted to fluticasone-equivalent doses on the basis of relative topical potency and what experts consider to be comparable doses according to the National Asthma Education Expert Panel report 2 see figure 3—5b and 3—5c in that report and the Canadian asthma consensus statement see table 8 in that statement. The RRs were adjusted for age matched by design , sex, severity of respiratory disease, and other conditions associated with a risk of pneumonia.

Comorbidity included cardiac disease defined by a prescription for cardiotropes, antihypertensives, diuretics or vasodilators; diabetes defined by insulin or oral hypoglycaemic agents; central nervous system drugs included benzodiazepines, major tranquillizers, anticonvulsants and drugs for parkinsonism; osteoporosis drugs included calcium, vitamin D and biphosphonates; antirheumatic drugs included gold salts, methotrexate, azathioprine, hydroxychloroquine and chloroquine.

Non-steroidal anti-inflammatory drugs, antidepressive agents and narcotics were considered as separate categories. Current ICS users were also classified as users of fluticasone, budesonide or other ICS beclomethasone, flunisolide or triamcinolone. Dose—response was assessed using the fluticasone-equivalent daily dose of current users classified as high, moderate and low.

It was further analysed by modelling the actual current fluticasone-equivalent daily dose continuously using cubic splines models. These models fit the dose—response curve using a cubic polynomial function separately within four mutually exclusive dose intervals, then imposing that the curves join at boundaries to generate a smooth continuous dose—response function.

A sensitivity analysis was performed by stratifying by prior COPD hospitalisation to address the possible inaccuracy of the COPD definition of our cohort and the fact that budesonide was most likely used more frequently for asthma in Quebec at the time of this study.

This is because, while neither budesonide nor fluticasone was indicated for use in COPD, the fluticasone—salmeterol combination was approved and therefore promoted for COPD during the time period under study while the budesonide—formoterol combination was not.

All analyses were conducted using SAS V. The mean duration of follow-up was 5. The cases had more severe respiratory disease, with more prescriptions for respiratory drugs, including oral corticosteroids and antibiotics. The cases had a slightly higher prevalence of comorbidity. Characteristics of cases of hospitalised or fatal pneumonia and their matched controls selected from a cohort of patients with COPD. Characteristics of controls selected from cohort of patients with COPD, according to current use of fluticasone and budesonide.

Crude and adjusted rate ratios of serious pneumonia associated with current use, dose and past use of inhaled corticosteroids among patients with COPD. Crude and adjusted rate ratios of serious pneumonia associated with current use and dose of the different ICS among patients with COPD.

Crude and adjusted rate ratios of serious pneumonia associated with current use of fluticasone and budesonide, stratified by prior COPD hospitalisation. These elevated risks disappeared within a few months of stopping the use of ICS. Systemic corticosteroids have been associated with increased risks of pneumonia in patients with rheumatoid arthritis. Our findings confirm the observations of several randomised trials of varying durations and doses. Our results confirm the subgroup analyses of the meta-analysis, suggesting that the risk is particularly elevated with high doses and start at short durations of use.

Moreover, the risk of pneumonia did not increase with the dose of budesonide. Furthermore, since a higher dose formulation was only available for the fluticasone—salmeterol combination, patients with more severe disease may have been more likely to have received a combination therapy containing fluticasone rather than budesonide. Therefore, data on this question from countries where budesonide has a greater market share would be a valuable addition to this evidence.

There is good evidence supporting the effect of ICS on human pulmonary host defence, acting through several biological pathways, such as an inhibitory action on macrophage functions, a decrease in cytokine production and nitric oxide expression, which may lead to a failure to control infection.

Fluticasone is known to be more potent ie, greater effect on intracellular steroid receptors , more lipophilic and has a longer half life than budesonide. It is therefore not surprising that a greater risk of oropharyngeal side effects is found with fluticasone compared with budesonide. Indeed, a more prolonged corticosteroid effect in the lungs and greater pulmonary retention will facilitate the local immunosuppressive action.

This study has strengths and some limitations. In this study, we defined serious pneumonia as a hospitalisation with a primary diagnosis of pneumonia or death from pneumonia, but did not have proof that the diagnosis was based on radiographic findings as these are not recorded in the RAMQ databases. However, it is most likely that as a primary inpatient diagnosis, it was in fact supported by a radiographic finding.

To address confounding by COPD severity, we adjusted for the number of prescriptions for respiratory medications other than ICS, and for exacerbations as measured by prescriptions for oral corticosteroids, antibiotics, as well as prior hospitalisations for pneumonia and COPD exacerbation.

Yet, residual confounding arising from unmeasured covariates can still be present. Of most concern is the possibility that budesonide may have been preferentially prescribed to patients with a lower risk of pneumonia, such as those with asthma or less severe COPD. In this specific study, however, our main results, adjusted for differences in severity, are consistent with those of several randomised trials which are inherently free of confounding, albeit less powerful with smaller study populations.

Exposure to ICS was measured from dispensed prescriptions so that one must assume that the drugs were actually taken. However, not taking these medications would actually tend to underestimate the true risk increase. Nevertheless, our definition likely captured some patients with asthma. One can expect that this would reduce the estimate of risk of ICS since ICS do not appear to increase the risk of pneumonia in patients with asthma. The dose—response effect with fluticasone that we found on the incidence of serious pneumonia, sustained over a long time, is important in the risk—benefit balance for patients with COPD.

In conclusion, high and low doses of fluticasone in patients with COPD are associated with an important increase in the risk of serious pneumonia, while the risk with budesonide is comparatively low, even at high doses, though it needs further examination in light of recent data and the possibility that patients receiving budesonide are inherently at lower risk of pneumonia than those prescribed fluticasone.

Further investigations into why the two popular ICS fluticasone and budesonide have such different effects on the risk of pneumonia are warranted. Contributors SS acquired the data.

Key messages What is the key question? What is the bottom line? Introduction Inhaled corticosteroids ICS are commonly used for the treatment of asthma and chronic obstructive pulmonary disease COPD , though their effectiveness for the latter remains controversial. Study design The source population for this study consisted of all subjects who, between and , were dispensed at least one prescription for any of the following respiratory medications: Pneumonia cases and controls Cases of serious pneumonia were defined as a hospitalisation for or death from pneumonia.

ICS exposure All prescriptions for ICS, alone or in a combination inhaler, dispensed between cohort entry and the index date were identified.
