NEEDLES AND SYRINGES FOR STEROIDS UK

This dosage is maintained for a period of 1—2 weeks, beyond which the dosage can be modified to an alternate day regimen. In patients who relapse when the dose of corticosteroids is reduced, itraconazole therapy can be especially useful [ 80 ]. As discussed previously for asthma and COPD, steroids afford a therapeutic effect in ABPA owing to their anti-inflammatory, immunosuppressive and bronchodilator effects.

Recent studies have explored the role of omalizumab in the management of ABPA [ 81 ]. Small-scale studies suggest that omalizumab may be useful as a steroid-sparing agent in patients with either asthma or CF who develop chronic ABPA [ 82 ]. Sarcoidosis is a multisystem disorder of unknown etiology characterized by the formation of non-caseating epithelioid cell granuloma.

This disorder occurs 10 times more frequently among African Americans as compared to Caucasians and the incidence is higher among young and middle-aged women. Interestingly, this disease affects non-smokers more often than people who smoke. Most commonly, the disease may be discovered incidentally when a chest radiograph reveals bilateral hilar lymphadenopathy. Patients may also present with a variety of clinical features including uveitis, xerophthalmia, parotidomegaly, xerostomia, lupus pernio, skin nodules, erythema nodosum, hypercalcemia, cardiac conduction system abnormalities, hepatomegaly and pulmonary infiltration.

Given the undetermined etiology of sarcoidosis, it is a histopathological diagnosis of exclusion [ 83 ]. Nevertheless, two clinical variants of sarcoidosis are well-recognized and may suggest a diagnosis of sarcoidosis in the absence of histopathological evidence. Uveoparotid fever is another term used to refer to this syndrome and, in the appropriate setting, may obviate the need for a biopsy [ 84 ]. The diagnosis of sarcoidosis requires histopathological evaluation and is one of exclusion since its etiology is unknown.

The hallmark feature on biopsies is the presence of non-caseating granuloma in different organs and tissues of the body without an alternative explanation. Laboratory investigations may also reveal elevated levels of ACE, although this is a non-specific finding. The differential diagnosis includes all granulomatous diseases, such as tuberculosis, histoplasmosis, berylliosis, silicosis and cat-scratch disease [ 83 ]. Management of sarcoidosis is dependent upon the severity and extent of the disease at the time of diagnosis.

Pulmonary sarcoidosis has been traditionally described to have four stages [ 86 ]. Fortunately, a substantial proportion of patients with pulmonary sarcoidosis do not require treatment as most of them have asymptomatic, non-progressive disease.

Treatment is necessary for patients who have severe disease at the time of presentation, those who report bothersome symptoms, or those who demonstrate evidence of progressive disease upon follow-up [ 87 ]. Likewise, in patients with extra-pulmonary disease, treatment is generally indicated to prevent end-organ damage. Once the patient shows evidence of clinical improvement, reduction in dosage of steroids can be started.

There is no evidence available to support a particular steroid tapering schedule. The usual duration of treatment with prednisone or equivalent steroid is almost 1 year. In cases where patients have disease refractory to steroids, patients experience relapses when steroids are tapered, or patients develop serious adverse effects related to steroids, steroid-sparing immunosuppressive agents methotrexate, azathioprine or biologic agents can be tried [ 88 ].

For patients who are at risk of steroid-induced adverse effects and have stage I-II pulmonary disease or evidence of slowly progressive disease , inhaled corticosteroid therapy may be a feasible alternative to systemic corticosteroids [ 89 ]. Budesonide — mcg inhaled twice daily has been most studied in this context. Fluticasone propionate — mcg inhaled twice daily is also a possible alternative option.

Collagen vascular diseases comprise of a group of disorders characterized by auto-immunity to antigens contained within blood vessels and extracellular matrix of various organs. A large number of diseases affecting connective tissue of the body are included under this heading. Sometimes, vascular diseases are also included in this category irrespective of whether auto-immunity is implicated in pathogenesis or not.

Nearly all collagen vascular diseases can affect the lung in a variety of ways. This is not surprising since the lungs are rich in both connective tissue and blood vessels. Abundant pulmonary vasculature is necessary for gaseous exchange, while abundant collagen and elastin fibers in the interstitium are necessary to support the dynamic chest wall—lung breathing system [ 90 ].

In the following lines, we briefly discuss the spectrum of pulmonary pathologies seen in various collagen vascular diseases and the role of steroids in their management. SSc is a disorder characterized by progressive fibrosis affecting multiple organs of the body including the skin, kidneys, lungs and other organs [ 91 ].

Within the pulmonary system, SSc can lead to the development of ground-glass opacities, which can slowly progress to fibrosis of the lung parenchyma. The most common pattern of pulmonary fibrosis seen in SSc is similar to that of usual interstitial pneumonitis UIP and may be histologically indistinguishable from rheumatoid lung or idiopathic pulmonary fibrosis IPF. In some cases, SSc may involve the lung in a pattern similar to that of idiopathic non-specific interstitial pneumonitis NSIP.

Progressive pulmonary impairment in SSc is a sign of worse prognosis and mandates aggressive treatment [ 92 ]. The decision to start treatment with immunosuppressive agents is based on clear evidence of progressive pulmonary damage as demonstrated by radiologic worsening or decline in pulmonary function as measured by PFTs. Two pharmacologic agents have been studied for the treatment of SSc-related interstitial lung disease ILD : mycophenolate and cyclophosphamide [ 93 ].

Mycophenolate is often prescribed as monotherapy and the usual duration of immunosuppressive therapy is approximately 2 years. Cyclophosphamide therapy can be given as intravenous injections or oral therapy and it is generally combined with corticosteroid therapy.

Oral cyclophosphamide is given daily and necessitates a higher cumulative dosage of the drug; on the other hand, intravenous cyclophosphamide is given once monthly and allows a lower cumulative dosage with a lower incidence of adverse effects. Cyclophosphamide therapy is continued for a few months and thereafter, it is transitioned to an alternative immunosuppressive agent such as azathioprine or mycophenolate.

Most clinicians prefer a daily oral dosage of low-dose prednisone 7. However, some small studies have also reported the use of pulse-dose methylprednisolone along with cyclophosphamide [ 94 ]. Generally, pulse steroid therapy should be reserved for patients with SSc who have another organ-threatening manifestation necessitating their use. PM and DM are auto-immune diseases that primarily affect muscles and skin, but in severe cases, involvement of other organ systems including the respiratory system can occur.

The pathogenesis of PM entails a primary injury to skeletal muscles that is mediated by T lymphocytes, while in DM, immune complex deposition occurs in blood vessels and skin followed by complement activation that leads to injury and inflammation of the skin and muscles [ 95 ]. ILD associated with PM or DM has been associated with the presence of antibodies against aminoacyl-transfer ribonucleic acid tRNA —synthetase and can occur as part of the antisynthetase syndrome [ 96 ].

Depending on the severity of the disease, glucocorticoid therapy alone or in association with other immunosuppressive agents may be required. In most patients who receive glucocorticoid therapy, another immunosuppressive agent usually azathioprine or mycophenolate is also started at the same time and continued for a prolonged period of time as glucocorticoids are tapered off.

SLE is a systemic auto-immune disease with protean manifestations that can affect nearly every organ-system of the body, but, occurs more frequently in women. Diagnosis is based on exclusion of alternative diagnoses and by applying the classification criteria proposed by the American College of Rheumatology or Systemic Lupus International Collaborating Clinics [ 99 ]. Aggressive immunosuppressive therapy i. Plasmapheresis may also be employed for the management of patients with DAH.

NSAID therapy if not contraindicated is used for patients with pleuritis [ ]. RA is an auto-immune disorder that results in chronic, symmetric, progressive, erosive polyarthritis which can affect any synovial joint of the body. NSAIDs may be used for management of pain. Short courses of systemic corticosteroids are used to manage acute exacerbations of RA.

Systemic corticosteroid therapy is also useful for patients who develop rheumatoid vasculitis or bronchiolitis obliterans. GPA is a necrotizing, granulomatous vasculitis that frequently affects the nose, paranasal sinuses, upper airways, lungs and kidneys [ ]. EGPA is a granulomatous vasculitis that is often associated with a history of asthma and eosinophilia, but can involve multiple organ-systems of the body [ ].

MPA is another ANCA-related small-vessel vasculitis that is non-granulomatous and can affect multiple organ-systems of the body, although it usually spares the paranasal sinuses and upper airways [ ]. GPS is an auto-immune disorder characterized by the formation of auto-antibodies against type IV collagen present in basement membrane. This disease principally affects the alveolar and glomerular basement membranes resulting in DAH and rapidly progressive glomerulonephritis respectively [ ].

Treatment of these disorders entails aggressive immunosuppression; pulse steroid therapy is combined with either rituximab or cyclophosphamide therapy. Patients who receive cyclophosphamide therapy are usually switched over to an alternative immunosuppressive agent, such as azathioprine or methotrexate. Patients who received rituximab initially may be maintained on the same agent or switched over to azathioprine or methotrexate [ ].

RPC is a rare auto-immune disease that leads to inflammation and destruction of cartilaginous structures of the body. Approximately one-third of cases occur in association with other rheumatologic diseases or malignancy.

Systemic corticosteroid therapy is used in patients with life or organ-threatening disease [ ]. Dapsone or other immunosuppressive agents may be used in combination with, or in place of, corticosteroids; evidence does not support the use of any particular immunosuppressive agent over others. Surgical treatment or airway stenting may be required in patients who develop laryngeal or tracheal disease [ ].

Eosinophilic pneumonitis may present either as an acute eosinophilic pneumonia or a more indolent chronic eosinophilic pneumonia. Patients with acute idiopathic eosinophilic pneumonia generally present with an acute febrile illness and progressive respiratory failure [ ].

Most patients have a history of new onset or resumption of cigarette smoking, although heavy inhalational exposure to fine sand and dust may also precipitate this illness. Peripheral eosinophilia is generally absent at presentation, although it may develop later in the disease. Computed tomography usually shows bilateral patchy ground-glass opacities or reticular infiltrates. Bronchoalveolar lavage BAL may reveal a preponderance of eosinophils. Lung biopsies usually show marked eosinophilic infiltration of the interstitium and alveolar spaces with DAD and absence of hemorrhage or granuloma [ ].

Most patients respond dramatically to steroids within 24—72 hours and respiratory failure resolves rapidly [ ]. Chronic eosinophilic pneumonia is an idiopathic disorder that presents with cough, fever, dyspnea and wheezing that progress over a period of several weeks to months. Treatment of chronic eosinophilic pneumonia is similar to that for acute eosinophilic pneumonia, although systemic corticosteroid therapy is generally tapered slowly over a period of 6 months or more [ ].

LIP is characterized by benign polyclonal proliferation of lymphocytes with infiltration of pulmonary interstitium and alveolar spaces with lymphocytes and plasma cells. This disorder often occurs in association with rheumatologic diseases or human immunodeficiency virus HIV infection [ ]. Thoracoscopic or open lung biopsies are necessary in most cases to confirm the diagnosis and exclude alternative diseases [ ]. Treatment of patients with asymptomatic disease may be watchful waiting with frequent monitoring.

For patients with symptomatic disease, systemic corticosteroid therapy usually prednisone 0. For patients who do not respond to steroids or relapse during taper, other immunosuppressive agents azathioprine, cyclosporine, cyclophosphamide or rituximab may be used [ ]. For patients with HIV infection, highly active antiretroviral therapy is used as first-line treatment instead of corticosteroid therapy. However, corticosteroid therapy will be needed for patients with HIV infection who continue to experience worsening LIP despite antiretroviral therapy [ ].

Infrequently, LIP may undergo malignant transformation and evolve into a pulmonary lymphoma. Prompt diagnosis of hypersensitivity pneumonitis is important as the disease is reversible in its early stages. Correct diagnosis is usually based on a compatible exposure history, clinical assessment, radiographic findings and response to avoidance of the suspected etiologic agent [ ].

Acute hypersensitivity pneumonitis often occurs following heavy exposure to an inciting agent and is usually confused with CAP. Patients present with fever, chest pain, cough and dyspnea about 6 hours following exposure. In most cases, symptoms improve within a few days after cessation of exposure to inciting agent, although radiographic resolution requires several weeks. Skin testing to allergens is not useful and serum precipitins may have a high false negative rate. Characteristic radiographic findings on computed tomography include mid-to-upper zone predominance of centrilobular ground-glass or nodular opacities with signs of air-trapping.

Subacute hypersensitivity pneumonitis presents with productive cough, dyspnea, fatigue, anorexia, and weight loss. Most patients have mixed obstructive and restrictive abnormalities on PFTs with a reduction in diffusion capacity. Radiographic findings may include diffuse micronodules, ground-glass opacities, or mild fibrotic changes predominantly involving the middle to upper lung zones.

Bronchoscopy with BAL may reveal lymphocytosis and negative cultures. Lung biopsy may reveal poorly formed, noncaseating granulomas in the pulmonary interstitium with fibrosis and bronchiolitis [ ]. Removal of the inciting agent results in complete resolution of findings over a longer period of time weeks to months and most patients require systemic glucocorticoid therapy.

In the chronic progressive form of hypersensitivity pneumonitis, patients present with cough, dyspnea, fatigue, and weight loss. Physical examination may reveal digital clubbing and hypoxemia. Radiographic studies will show widespread pulmonary fibrosis; BAL may reveal lymphocytosis. Lung biopsy is necessary to demonstrate granulomatous pneumonitis, diffuse interstitial pneumonitis, bronchiolitis obliterans and distal destruction of alveoli honey-combing with densely fibrotic zones [ ].

At this stage, removal of exposure to the inciting agent will only lead to partial improvement. Corticosteroid therapy usually 0. Gradual tapering of steroid dosage can be started after 2 weeks and tapered over the ensuing 2—4 weeks in most patients [ ].

In patients with chronic hypersensitivity pneumonitis and extensive pulmonary fibrosis, lung transplantation may be a viable treatment option. IIP refer to a group of idiopathic ILDs that are characterized by infiltration of the pulmonary interstitium with inflammatory cells and consequently result in progressive fibrosis. IIP is a broad umbrella category that includes a number of different disease entities with distinct histologic patterns, natural course and prognosis [ ].

IPF usually presents in the sixth to seventh decades of life. Typical radiologic findings include bibasilar subpleural fibrosis with traction bronchiectasis and honeycombing in the later stages. IPF is characterized histologically by a UIP pattern with a temporal and geographical heterogeneity, patchy involvement of the lung parenchyma, presence of architectural distortion and fibroblast foci and absence of features suggesting an alternative pattern [ ]. Two novel tyrosine kinase inhibitors—pirfenidone and nintedanib—have been approved for the treatment of IPF [ ].

Despite this, the overall prognosis for IPF remains poor. Systemic corticosteroid therapy is often employed for patients who develop acute infective exacerbation of IPF, although high quality evidence in support of this practice is lacking [ ]. Histologically, NSIP is characterized by temporal and geographical homogeneity with uniform involvement of the lung parenchyma, mononuclear cell infiltration of the interstitium and relative preservation of lung architecture [ ].

Radiologic findings include bibasilar subpleural reticular shadowing with traction bronchiectasis, ground-glass opacities and absence of honeycombing. Alternative causes of NSIP, such as collagen vascular diseases, drugs and infections, need to be excluded.

Pulse-dose methylprednisolone therapy has also been used in those with severe disease on presentation. In patients who relapse or remain refractory despite systemic corticosteroid therapy, a second immunosuppressive agent is added to prednisone. Cigarette smokers tend to have a number of subclinical pulmonary interstitial abnormalities identifiable on histopathology [ ]. Langerhans cell histiocytosis is a separate disease entity and is generally not included under the heading of IIP.

Both DIP and RB-ILD occur in smokers, usually with a smoking history of over 30 pack-years, most often in the third to fourth decades of life; men are more commonly affected [ ]. In DIP, radiologic studies reveal bilateral ground-glass opacities without the peripheral reticular shadowing typical of UIP. In RB-ILD, radiologic findings may include scattered ground-glass opacities along with bronchial wall thickening.

DIP is actually a misnomer as these macrophages were originally believed to be desquamated pneumocytes. A smoker macrophage is a macrophage that contains fine brown pigment flecked with tiny blackish particles; these cytoplasmic particles stain well with Prussian blue iron content and periodic acid Schiff polysaccharides stains.

RB-ILD has a histopathological appearance somewhat similar to DIP in that numerous smoker macrophages are noted; however, these pigmented macrophages are abundant within the lumen of respiratory bronchioles [ ].

Moreover, the histopathological findings seen in RB-ILD have a bronchiolocentric distribution, whereas DIP tends to affect the lung in a rather uniform and diffuse manner. For patients who continue to experience symptoms and have worsening PFTs, systemic corticosteroid therapy is used. Rarely, other immunosuppressive agents may be used if patients do not improve, although evidence in this regard is scarce. Given the considerable overlap between RB-ILD and DIP, some researchers have suggested that the two categories may be merged together into a single group [ ].

This clinical disorder is characterized by an inflammatory pneumonitis and a proliferative bronchiolitis that results in excessive proliferation of granulation tissue within the smaller airways [ ]. COP often presents with an acute or subacute clinical picture and mimics CAP with a lack of response to antibiotics.

Patients are most often in their fifth or sixth decades of life and both sexes are affected equally. In many cases, a flu-like illness may precede the onset of COP. As is the case with other IIP, secondary causes of organizing pneumonia such as drugs, collagen vascular diseases and infections need to be excluded.

PFTs reveal a restrictive defect with impairment of gaseous exchange diffusion capacity. Radiologic studies show multiple patchy ground-glass opacities or peripheral consolidations [ ]. Bronchoscopy with BAL is often performed to exclude other diagnoses such as infections, drug-induced pneumonitis, hypersensitivity pneumonitis, chronic eosinophilic pneumonitis and malignancy. Although transbronchial lung biopsy may be performed at the time of bronchoscopy, most patients suspected of having COP or other ILD require a thoracoscopic or open lung biopsy i.

Systemic corticosteroid therapy is the mainstay of treatment. Patients usually respond clinically to corticosteroids within a few days to a few weeks. Corticosteroid therapy is generally tapered over a period of 6—12 months. Other immunosuppressive agents may be used in patients who have COP refractory to steroids, or those who relapse frequently despite moderate doses of corticosteroids [ ].

AIP also known as Hamman-Rich syndrome has a much more aggressive and acute disease course as compared to other ILD and it is similar to acute respiratory distress syndrome ARDS in terms of its worse prognosis. Clinically, it presents with acute onset of rapidly worsening respiratory failure with diffuse airspace shadowing on plain radiographs. The histologic hallmark of AIP is DAD as characterized by diffuse airspace organization with or without the formation of hyaline membranes and alveolar septal thickening due to diffuse organizing fibrosis with a geographic and temporal homogeneity [ ].

As for other IIP, cultures should be negative and granulomas, viral inclusions or eosinophils should be absent on histopathology. Laryngotracheitis also known as croup is a viral infection caused by parainfluenza viruses most commonly, type 1 and often affects children in the first 3 years of life with a slight predisposition for boys.

Clinical symptoms include low-grade fever, dyspnea, inspiratory stridor and a characteristic barking cough. In older children, hoarseness may also be noticeable. In some cases, inflammation may extend to the lower airways and result in laryngotracheobronchitis or even superimposed bacterial laryngotracheobronchopneumonitis [ ]. While croup is typically caused by parainfluenza viruses, other viruses may also cause croup in certain cases; these include respiratory syncytial virus, influenza virus, rhinoviruses and human metapneumoviruses [ ].

Plain chest radiographs may show narrowing of the subglottic area, frequently referred to as the steeple sign—owing to its resemblance to the steeple of a church. It should be noted here that croup is different from bacterial tracheitis, acute epiglottitis and viral bronchiolitis. Bacterial tracheitis is a bacterial infection of the trachea that results in a thick purulent exudate in the trachea, frequently with involvement of the lower airways tracheobronchopneumonitis [ ].

Most cases in vaccinated children and adults are caused by streptococcal or staphylococcal infections. Epiglottitis generally has a more rapid onset and aggressive course than croup and children tend to have high-grade fever and a toxic appearance [ ]. Airway obstruction may be precipitated by physical examination or manipulative procedures, such as laryngoscopy. Viral bronchiolitis is an infection that usually occurs in infants and children below the age of 2 years.

Most infections are caused by respiratory syncytial virus and present with fever, cough, dyspnea and wheezing [ ]. Bronchiolitis is treated with supportive care only and corticosteroids have no role in management. Treatment of croup involves supportive care with humidified oxygen therapy and anti-pyretics, adequate hydration, corticosteroids and nebulized epinephrine [ ].

A strong body of evidence suggests that the use of either nebulized budesonide or single-dose dexamethasone provides benefits in terms of reducing length of hospital stay and decreasing visits to the emergency department [ ]. The Westley croup score can be used to grade the severity of croup [ ]. Patients with mild croup may be managed at home with a single dose of oral dexamethasone 0.

Patients with moderate croup may be admitted to the hospital and administered an intramuscular or intravenous dose of dexamethasone along with repeated nebulizations of epinephrine [ ]. CF is an autosomal recessive disorder that results from genetic mutations in the cystic fibrosis transmembrane conductance regular CFTR chloride channel. CF is the most common lethal genetic disorder in the European population with an incidence of about 1 in live births [ ]. Despite the development of novel targeted therapies for CF patients [ ], the median survival for CF patients remains at 37 years—although it has been consistently improving over the past few decades [ ].

In patients with CF, defective functioning of the CFTR gene results in protean manifestations, such as sinonasal polyposis, bronchiectasis, chronic pancreatitis with pancreatic insufficiency, CF-related diabetes mellitus, gut pathologies meconium ileus, meconium ileus equivalent and intestinal atresia , osteoporosis, malnutrition, infertility and delayed puberty [ ]. However, the most disabling of these manifestations is lung disease; defective mucociliary clearance leads to recurrent and persistent infections with virulent organisms, resulting in progressive and cumulative lung damage and development of bronchiectasis and end-stage lung disease [ ].

Patients with CF frequently present with recurrent and disabling infective exacerbations of their lung disease. The microbiologic agents implicated in pneumonia and lower respiratory tract infections among patients with CF are distinct from that of the general population [ , , , ].

The management of pulmonary disease in patients with CF is best carried out in dedicated CF centers with a multidisciplinary team that is experienced in the care of such patients [ ]. In patients presenting with acute infective exacerbations of CF, good evidence is available to substantiate the role of antibiotics, pulmonary toilet, bronchodilators, ventilatory support and mucolytics [ ]. The use of corticosteroids in the management of patients with CF is controversial.

Systematic reviews of randomized controlled trials suggest that the use of inhaled or systemic corticosteroid on a chronic basis in patients with CF without evidence of asthma or ABPA causes more harm than meaningful benefits [ , ]. However, in patients with CF who present with an acute infective exacerbation, some data suggest that short-term corticosteroid therapy may be beneficial. In a randomized controlled trial, Tepper and colleagues demonstrated that use of a short course of intravenous hydrocortisone in patients with acute infective exacerbation of CF provided a greater and sustained improvement in pulmonary function [ ].

ARDS is the development of acute hypoxic respiratory failure in response to an identifiable inciting event, which is characterized pathologically by a diffuse inflammatory process involving the lung that leads to increased vascular permeability, generalized alveolar edema, loss of aerated tissue and markedly decreased lung compliance [ ].

ARDS can occur in response to a wide range of etiologies including sepsis, acute pancreatitis, trauma, drowning, burns, aspiration, transfusion-related acute lung injury, and so on; however, all these clinical entities are grouped together under the heading of ARDS as their clinical management is similar [ ]. Clinically, ARDS presents with worsening hypoxemia and respiratory failure that develops within 24—72 hours of an inciting event.

Patients typically have severe tachypnea and hypoxemia with accessory muscle use and respiratory distress on examination; chest auscultation may reveal bilateral diffuse crackles. Plain radiographs reveal bilateral airspace shadowing, which may be patchy in the initial stages, and coalesce later to a more homogeneous pattern in later stages. Arterial blood gas analysis will typically show respiratory alkalosis with hypoxemia and an elevated A—a gradient.

The degree of hypoxemia can be quantified by the ratio of PaO 2 to the fraction of inspired oxygen FiO 2 [ ]. Computed tomography reveals widespread airspace opacities that may coalesce and are more prominent in the dependent parts of the lung. Management of ARDS is centered on mechanically ventilating patients with lung protective strategies.

Low tidal volume ventilation is the mainstay of management while tolerating permissive hypercapnia and using high PEEP to maximize alveolar recruitment and prevent atelectasis [ ]. In patients with very severe ARDS, prone positioning techniques and extra-corporeal membrane oxygenation may be necessary to support life [ ]. The use of corticosteroids in patients with ARDS is controversial and remains contentious to date.

Moreover, in patients who develop ARDS due to a steroid-responsive etiology, corticosteroids should be used early in the course of the disease [ ]. Several meta-analyses have been published to evaluate the impact of steroids on mortality in ARDS and their results have been conflicting.

Three meta-analyses suggest that there is no benefit of steroids in terms of overall mortality, but, they help to improve gas oxygenation, reduce duration of mechanical ventilation and decrease overall stay in the ICU [ , , ]. Two other meta-analyses reported that use of systemic corticosteroids provided a reduction in overall mortality and reduced the duration of mechanical ventilation [ , ]. In the light of such conflicting evidence, use of systemic corticosteroids in patients with severe ARDS remains at the discretion of the treating clinician.

Critical care physicians should assess each case individually and decide whether to administer corticosteroids or not based on their perceived benefits and possible adverse effects. Both single-lung and double-lung transplantation procedures are increasingly being performed; however, the availability of donor lungs is the main limiting factor to the number of procedures that can be performed.

Apart from these absolute contraindications, there are a number of other diseases or conditions that are considered relative contraindications to lung transplant. Interestingly, use of systemic corticosteroids perioperatively was prohibited in the past due to concerns of poor healing of the newly formed anastomosis [ ]. However, most evidence has shown that use of prednisone in doses of up to 0.

Corticosteroids are an important part of immunosuppressive therapy for patients undergoing lung transplantation. Corticosteroid therapy is then continued at a dose of 0. For induction therapy, the most commonly used agents are basiliximab, alemtuzumab or anti-thymocyte globulin [ ].

Pre-medication with acetaminophen, diphenhydramine and corticosteroids methylprednisolone mg IV once is required prior to infusion of alemtuzumab or anti-thymocyte globulin. Maintenance immunosuppression is then employed with a combination regimen consisting of a glucocorticoid usually prednisone , a calcineurin inhibitor usually tacrolimus or cyclosporine and an anti-metabolite usually mycophenolate or azathioprine [ ].

Occasionally, an mTOR mechanistic target of rapamycin inhibitor, such as sirolimus or everolimus, may also be used be as part of the maintenance immunosuppressive regimen; however, mTOR inhibitors should not be used in the first 3 months post-lung transplant as they may lead to fatal bronchial dehiscence [ ]. Transplant rejections represent a significant problem in the world of transplantology. Corticosteroid therapy forms an integral component of the management of both acute and chronic graft rejections.

From a pathological perspective, graft rejection can be cell-mediated or humoral graft rejection depending on whether cytotoxic T lymphocytes or antibodies are implicated in immunopathogenesis respectively. In chronologic terms, rejection is classified into hyperacute, acute or chronic rejection based on temporality [ ]. Hyperacute rejection occurs within 24 hours of transplantation usually in the first few minutes to hours and results in severe hypoxemia and other signs of graft failure.

Such a graft rejection occurs due to preformed circulating antibodies in the recipient that are directed against antigens of the donor. All patients who develop hyper-acute rejection are already on high-dose steroids as part of their usual post-transplant care. Additional therapies, such as bortezomib proteasome inhibitor or eculizumab monoclonal antibody to C5 complement protein , are also employed in most cases.

Acute lung allograft rejection usually occurs within the first 6—12 months of transplantation and it is cell-mediated in most cases. In acute cellular lung graft rejection, treatment is with pulse-dose methylprednisolone along with intensification of the maintenance immunosuppressive regimen [ ]. Cases of acute humoral lung graft rejection developing weeks to months after transplantation are less common. Empiric antibiotics are often initiated in patients with acute lung graft rejection until results of microbiologic and histopathological studies are available.

Chronic lung transplant rejection remains a major source of late morbidity and mortality for lung transplant recipients [ ]. Chronic lung allograft rejection may manifest as either bronchiolitis obliterans or a restrictive allograft syndrome. Bronchiolitis obliterans is the predominant subtype of chronic lung graft rejection and has a worse prognosis [ ]. It is usually detected as an obstructive defect on PFTs. Histopathologically, fibrosis in the lower airways bronchioles with formation of dense scar tissue is typical [ ].

In some patients, an unexplained obstructive defect on PFTs is noted in the absence of definitive histopathological evidence of bronchiolitis obliterans; such patients are termed to have bronchiolitis obliterans syndrome. In restrictive allograft syndrome, patients have a demonstrable restrictive defect on PFTs and evidence of fibrotic changes involving the upper lung lobes [ ]. In most cases, chronic lung allograft rejection is irreversible and most patients eventually require retransplantation [ ].

In many of the chronic diseases discussed in this chapter, toxicities of steroid therapy are a major source of morbidity. Additionally, most patients with such chronic diseases are often on immunosuppressive therapy or other toxic medications that may lead to cumulative toxicity. While systemic glucocorticoid therapy is associated with the most number of adverse effects, inhaled glucocorticoid therapy can also have some adverse effects, although they tend to be generally less severe [ 40 , 41 , 42 ].

Moreover, some of the adverse effects of corticosteroids do not manifest until complications develop. For instance, loss of bone mineral density may go on unchecked until a patient develops vertebral collapse [ ]. Luckily, most of the adverse effects of steroids are potentially reversible with time once corticosteroids are discontinued.

Side effects of systemic corticosteroids pertain to almost all systems of the body. Long-term corticosteroid therapy can cause skin thinning, dermal atrophy and purpura, especially on the dorsum of hand and forearm [ ].

Dermal atrophy is a consequence of reduced collagen synthesis due to inhibition of protein synthesis. Purpura is a combined consequence of dermal atrophy and increased fragility of vessels, which predisposes to bleed in response to minor stress.

In a case—control study, Karagas and co-workers reported that the risk of non-melanoma skin cancer was increased among patients who used corticosteroids [ ]. Cushingoid striae occur due to overstretching of the skin with rupture of vessels within the skin. Steroid-induced acne is also a well-known dermatologic adverse effect of steroids [ ].

Ophthalmic adverse effects of corticosteroids include cataracts, increased intraocular pressure and development of glaucoma [ ]. Cataracts most commonly occur in a posterior subcapsular location and are often bilateral [ 41 ]. Central serous chorioretinopathy is another rare ophthalmic side effect of corticosteroids [ ].

Redistribution of body fat with truncal obesity, buffalo hump and moon facies Cushingoid features develop when corticosteroids are used over a long period of time in high doses [ ]. Prolonged periods of hyperglycemia predispose patients to the development of diabetes mellitus and central adiposity, which in turn leads to increasing insulin resistance.

Insulin resistance and hyperinsulinemia lead to increased synthesis of very low-density lipoproteins and increase triglyceride levels and adipose tissue in the body [ ]. Moreover, since many pharmacologically used corticosteroids have weak mineralocorticoid properties, they can lead to fluid retention, hypertension, hypokalemia and mild metabolic alkalosis.

All these effects can culminate in accelerated atherosclerosis and increased incidence of cerebrovascular events and coronary artery disease [ ]. Moreover, fluid retention and hypertension can worsen cardiac failure. Fluid retention can also be problematic in patients with pre-existing renal disease. In the gastrointestinal system, corticosteroids can lead to a number of adverse effects including gastritis and gastrointestinal bleeding [ ].

Corticosteroids may also impair healing of peptic ulcers and mask signs of gastrointestinal perforation; however, in patients taking glucocorticoids alone, routine use of proton pump inhibitors is not recommended [ ]. Proton pump inhibitors should be given to patients who are taking corticosteroids along with either aspirin or other NSAIDs [ ]. Fatty liver is another adverse consequence of prolonged corticosteroid use. In the musculoskeletal system, glucocorticoids lead to accelerated bone loss due to decreased osteogenesis and increased osteolysis [ ].

Corticosteroid use can lead to osteoporotic fractures; interestingly, vertebral fractures have been reported in patients treated with glucocorticoids, even with a normal bone mineral density [ ]. Avascular necrosis, especially of the head of femur, is a serious adverse effect of glucocorticoid therapy [ ]. In children, prolonged use of corticosteroids can lead to slowed growth or even, permanent growth impairment [ ]. Corticosteroids can also lead to myopathy, which manifests as proximal muscle weakness, although muscle enzymes serum creatine kinase are within normal limits [ ].

With respect to the reproductive system, corticosteroid use may lead to menstrual irregularities and decreased fertility in both sexes [ ]. Moreover, use of high doses of corticosteroids during the first trimester of pregnancy may elevate the risk of cleft palate slightly [ ]. The risk of fetal intrauterine growth restriction is also elevated in women who take corticosteroids throughout pregnancy [ ].

Corticosteroids have also been shown to have a number of adverse effects on the central nervous system, especially when used in high doses [ ]. Neuropsychiatric effects may include feeling of euphoria, anxiety, depression, mania, delirium or even psychosis.

In a study by Shin et al. In another study by Keenan and colleagues [ ], use of corticosteroids was associated with an adverse outcome on explicit memory at a period of 1 year. Last, but not the least, the immune system is also adversely affected by glucocorticoid therapy and immunosuppression leads to an increased risk of infections, decreased response to vaccines, poor wound healing and lymphopenia [ , ]. Neutrophilia seen with corticosteroid therapy is a mere consequence of demargination of the neutrophil pool.

Close monitoring of such patients for the development of adverse effects is essential [ ].
