Candidiasis with corticosteroids

Salbutamol is a selective beta2-receptor agonist indicated in the management of asthma as a bronchodilator relieving acute attacks. It may be used in combination with inhaled corticosteroids such as beclometasone. Salbutamol acts within a few minutes and tends to be short-acting, unlike salmeterol. Side-effects of salbutamol include tachycardia and palpitations. It does not cause drowsiness and does not precipitate oral candidiasis. Inhaled corticosteroids may precipitate oral candidiasis.

Inhaled steroids (commonly used are beclomethasone, budesonide, triamcinolone, fluticasone, flunisolide) appear to attenuate the inflammatory response, to reduce bronchial hyperreactivity, to decrease exacerbations and to improve health status they may also reduce the risk of myocar dial infar ction, but they do not modify the longterm decline in lung function. Whether- steroids affect mortality remains unclear. Many patients appear to be resistant to steroids and large, long-term trials have shown only limited effectiveness of inhaled corticosteroid ther apy. Certainly, the benefit from steroids is smaller in COPD than in asthma. Topical side-effects of inhaled steroids are oropharyngeal candidiasis and hoarse voice. At the normal doses systemic side-effects of inhaled steroids have not been firmly established. The current recommendation is that the addition of inhaled gluco-coiticosteroids to bronchodilator treatment is appropriate for patients with severe to veiy sever e COPD. 

CORTICOSTEROID INHALANTS. The inhalers, particularly die corticosteroid or mast cell aerosols, may cause tiiroat irritation and infection with Candida albicans. The nurse instructs the patient to use strict oral hygiene, cleanse die inhaler as directed in die package directions, and use die proper technique when taking an inhalation. These interventions will decrease die incidence of candidiasis and help to soodie die throat. Occasionally an antifungal drug may be prescribed by die primary health care provider to manage the candidiasis. 

Because all inhaled corticosteroids are equally effective if given in equipotent doses, product selection should be individualized based on the available dosage form, delivery device, and patient preference. In infants, administration may require the use of a nebulizer or spacer/holding chamber with a facemask. Caregivers should use a soft, damp cloth to wipe the face of infants receiving an inhaled corticosteroid via a facemask to prevent topical candidiasis.18... 

Assess the patient for adverse effects, particularly candidiasis and dysphonia associated with inhaled corticosteroids. 

The most common adverse effects from inhaled corticosteroids include oropharyngeal candidiasis and hoarse voice. These can be minimized by rinsing the mouth after use and by using a spacer device with metered-dose inhalers. Increased bruising and decreased bone density have also been reported the clinical importance of these effects remains uncertain.1,2,19... 

Systemic toxicity of inhaled corticosteroids is minimal with low to moderate inhaled doses, but the risk of systemic effects increases with high doses. Local adverse effects include dose-dependent oropharyngeal candidiasis and dys-phonia, which can be reduced by the use of a spacer device. The ability of spacer devices to enhance lung delivery is inconsistent and should not be relied on. 

Side effects of inhaled corticosteroids are relatively mild and include hoarseness, sore throat, oral candidiasis, and skin bruising. Severe side effects such as adrenal suppression, osteoporosis, and cataract formation are reported less frequently than with systemic corticosteroids, but clinicians should monitor patients receiving high-dose chronic inhaled therapy. 

Deltacortil is a proprietary preparation of the corticosteroid prednisolone. As with other corticosteroids, prednisolone may lead to precipitation of osteoporosis, insomnia and candidiasis. 

Side-effects and disadvantages of inhaled corticosteroids include hoarseness and oral candidiasis. Patients on inhaled corticosteroids are advised to rinse their mouth with water after using the inhaler, to reduce the occurrence of such...

Local adverse effects from ICSs include oropharyngeal candidiasis and dysphonia that are dose-dependent. The dysphonia appears to be due to a local corticosteroid-induced myopathy of the vocal cords. The use of a spacer device can decrease oropharyngeal deposition and thus decrease the incidence and severity of local side effects. In infants who require delivery through a facemask, the parent should clean the nasal-perioral area with a damp cloth following each treatment to prevent topical candidal infections. 

In a retrospective study of rheumatoid arthrihs pahents treated with leflunomide risk factors of severe infections were identified. Among the 401 patients that started on leflxmomide therapy, 8.2% developed severe infections (pneumonia, oral candidiasis, pyelonephrihs, pulmonary tuberculosis, cellulitis, disseminated herpes zoster, tonsil-lihs and pulmonary cryptococcosis). Risk factors for severe infections were older age, presence of diabetes mellitus and (increasing) daily dosage of corticosteroids [Sl ]. 

Another meta-analysis compared the efficacy and safefy of mometasone versus other inhaled corticosteroids, in patients with moderate to severe asthma [5 ]. The meta-analysis included 1354 asthmatics across six trials with study durations of at least 4 weeks. Mometasone appeared to have similar incidence in all treatment-related adverse events compared to ICS (OR = 1.06, 95% Cl = 0.74,1.52). No significant difference in the discontinuation rate, the frequency of oral candidiasis, pharyngitis, headache, or dysphonia was found between mometasone to other ICS. 

Fungal Infections Although fxmgal upper respiratory tract colonisation and infections are known adverse effects of inhaled corticosteroids, only recently a fxmgal lower respiratory fracf infection, and more specifically a case of Candida pneumonia in a neonate, was attributed to ICS [11 ]. The neonate received inhaled beclomethasone therapy (400 xg, six times a day) for bronchopulmonary dysplasia. After 20 days of freafment, the patient developed a lower respiratory tract infection. Klebsiella pneumoniae was isolated in fhe fracheal aspirate and treated with amnxirillin-clavulanate without clinical improvement. A week later, bronchoscopy was performed and extended candidiasis was found and treated successfully with fluconazole. Candida pneumonia secondary to airway colonisation is rare and in this case, it was likely provoked by the ICS treatment. 

Studies of oropharyngeal deposition in healthy subjects (30-32), as well as in patients with asthma (33) have shown wide interindividual variations. For instance, deposition in the oropharynx of inhaled 3.6-pm test particles varied between 10 and 70% in asthmatics. This implies that the dose of a therapeutic aerosol in the lungs is difficult to predict and is sometimes suboptimal. Furthermore, adverse effects of inhaled corticosteroids, such as oral candidiasis (34), dysphonia (35), and osteoporosis (36), may arise locally and systematically. It is evidently important to reduce a high oropharyngeal deposition.
