Insights

High-dose fluticasone propionate (FP) inhalers increase Candida colonization risk in asthma patients. Not washing the throat and prolonged inhaled corticosteroid (ICS) use are key risk factors.

Area of Science:

  • Medical Science
  • Pharmacology
  • Infectious Diseases

Background:

  • Oropharyngeal candidiasis is a potential side effect of inhaled corticosteroid (ICS) therapy.
  • Fluticasone propionate (FP) is a commonly prescribed ICS for asthma management.

Purpose of the Study:

  • To investigate the frequency of oropharyngeal candidiasis and its clinical correlates in asthmatic patients using fluticasone propionate (FP) via a dry powder inhaler.
  • To identify risk factors associated with Candida colonization in ICS-treated asthmatic patients.

Main Methods:

  • Comparative study involving four groups: asthmatics on 200 microg/d FP, 500 microg/d FP, no ICS, and healthy controls.
  • Analysis of Candida colonization rates and correlation with clinical factors, including throat hygiene and duration of ICS use.

Main Results:

  • Higher Candida colonization frequency observed in asthmatics using 500 microg/d FP compared to those without ICS and healthy controls.
  • No significant difference in colonization for the 200 microg/d FP group versus controls.
  • Throat washing (OR=9.4) and ICS use >12 months (OR=2.5) were significant predictors of Candida colonization.

Conclusions:

  • Higher doses of fluticasone propionate (FP) are associated with increased Candida colonization in asthmatics.
  • Inadequate throat hygiene and extended inhaled corticosteroid (ICS) use duration are critical determinants for oropharyngeal candidiasis in asthmatic patients.

Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...
Dosage Regimen: Fixed Dose01:01

Dosage Regimen: Fixed Dose

Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...
Dosage Regimen: Multiple Oral Dosage01:25

Dosage Regimen: Multiple Oral Dosage

Understanding how a drug's concentration fluctuates within the body over time is crucial in pharmacokinetics, particularly with multiple oral doses. A graphical representation of multiple oral dosages provides insight into these dynamics. Typical accumulation curves of a drug's concentration in the body reveal a sawtooth pattern, indicating periodic peaks and troughs correlating with each dose administration and the drug's subsequent elimination.The plasma concentration at any time during an...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by anesthetizing...
