title: Severe steroid-dependent asthma with IgG-2 deficiency and recurrent sinusitis: response to treatment with high-dose intravenous immunoglobulin.
abstract: Patients with severe asthma pose a dilemma to the physician since the treatment they need, namely high doses of oral steroids, has serious side effects, especially among the pediatric population. Deficiency in one or more of the IgG subclasses has been associated with abnormal pulmonary function, as well as with recurrent sinopulmonary infections in adults and children. In the last years attention has been focused on alternative therapies for these patients. One of these alternatives is the treatment with intravenous immunoglobulin (IVIG). We report an 11-year-old boy with severe asthma since the age of two years and multiple hospital admissions due to asthmatic crisis even more frequent and severe, to the point of needing, in the last year, daily treatment with high doses of oral steroids (20 mg). During six months the patient was given high doses of intravenous immunoglobulin. After one month of treatment a clinical and spirometric improvement was apparent allowing to taper down the oral steroids until their complete substitution by inhaled budesonide (1,600 microg/day). The only side effects noted were severe headaches after gammaglobulin infusions which responded well to oral paracetamol. This improvement was sustained throughout the treatment period, but few weeks after the IVIG was suspended the clinical and spirometric parameters started to worsen again.
