[Life-threatening swelling of the tongue in antihypertensive therapy with ACE inhibitors]

[Chronic hyperplastic laryngitis following treatment of hypertension with angiotensin converting enzyme-inhibitor]

We report the case of a 42 year old patient who developed chronic hyperplastic laryngitis during treatment with the angiotensin converting enzyme-inhibitor Cibacen 10. A severe cough and vocal restrictions with hoarseness were only incompletely cured after changing this anti-hypertensive medication to a adrenergic blocker, combined with a vocal rest and anti-inflammatory inhalation. Therefore we performed a laryngoscopy under general anesthesia and excised the swelling of the vocal cords. Additionally, voice therapy was prescribed and complete restitution achieved. Although hoarseness is documented as a potential side effect of angiotensin converting enzyme-inhibitors, morphological alterations in the vocal cords have not been linked to this type of drug. In our case, prolonged medication with Cibacen 10 led to chronic hyperplastic laryngitis. Initial coughing might have induced the trauma of the epithelium of the vocal cords. Due to the morphological alterations to the vocal cords the patient developed additional functional dysphonia.

Massive tongue swelling following the use of synthetic saliva

A 5-year-old boy with cerebral palsy and severe learning difficulties developed massive tongue swelling of sudden onset following the use of synthetic saliva. Acute airway obstruction and severe stridor ensued which required tracheal intubation and transfer to paediatric intensive care. The child was treated with intravenous steroids, antihistamines and epinephrine. With cessation of synthetic saliva, the swelling gradually resolved and the child was extubated on day 5.

Angiotensin-converting enzyme inhibitor therapy for ventricular dysfunction in infants, children and adolescents: a review

Angiotensin-converting enzyme (ACE) inhibitors have become an important part of the pharmacologic armamentarium in the battle against treatment of ventricular dysfunction. There have been a number of large controlled, randomized trials in adults with both asymptomatic and symptomatic ventricular dysfunction, which confirm the safety and efficacy of this category of drugs for the treatment of this potentially lethal condition. ACE inhibitors may be used to treat infants, children and adolescents with asymptomatic and symptomatic ventricular dysfunction as well. The data supporting their use in children is less complete than that concerning the treatment of adults. We review here the various causes of ventricular dysfunction and congestive heart failure (CHF) in infants, children, and adolescents; the data available regarding treatment of these conditions with ACE inhibitors, and the safety and efficacy of these drugs for the various conditions. The pharmacokinetics and proposed mechanisms of action of ACE inhibitors in children are reviewed, as are speculated long-term results of ACE inhibitor use in cohorts of growing children. Recommendations are made for future studies.
