RESUMO

BACKGROUND/AIMS: Atopy is closely related to asthma and is a risk factor for the development and exacerbation of asthma. The aim of this study was to evaluate the association between exercise-induced asthma (EIA) and atopy in adult patients with asthma-like symptoms. METHODS: Forty young male patients with asthma-like symptoms were enrolled. Skin prick, methacholine bronchial provocation, and exercise provocation tests were performed. Current and ex-smokers were excluded. RESULTS: Exercise provocation tests were positive in 21 patients (52.5%). Airway hyperresponsiveness (AHR) to methacholine (85.7% vs. 42.1%, p = 0.007) and atopy (85.7% vs. 47.4, p = 0.017) was found more frequently in patients with EIA than in those without EIA. EIA was significantly associated with atopy score (16.5 +/- 3.0 vs. 6.5 +/- 2.0, p = 0.011), atopy index (2.1 +/- 0.3 vs. 1.0 +/- 0.3, p = 0.004), and positive responses to Dermatophagoides pteronyssinus (76.2% vs. 42.1%, p = 0.028) and Dermatophagoides farinae (76.2% vs. 36.8%, p = 0.012), but not with positive responses to pollen allergens. AHR to methacholine (odds ratio [OR]: 14.3, 95% confidence interval [CI]: 1.86-109.4) and atopy (OR: 16.9, 95% CI: 2.04-140.74) were significant risk factors for EIA. CONCLUSIONS: Atopy was a risk factor for EIA in young adult men, and sensitization to house dust mites was associated with EIA.

RESUMO

The combination therapy of pegylated interferon and ribavirin is the mainstay of treatment for chronic hepatitis C patients. Anti-viral therapy is commonly associated with side effects such as headache, fever, myalgia, and arthralgia. However, anti-viral therapy can continue because these side effects are mostly mild and can be improved with supportive management. Anti-viral therapy should be stopped promptly if serious side effects, such as interstitial pneumonitis or hemolytic anemia occur, although those serious side effects are rare. There were a few case reports of interferon-related interstitial pneumonitis worldwide. In Korea, one atypical case report of interstitial pneumonitis has been reported, which followed the combination therapy of interferon-alpha and ribavirin in a patient with chronic hepatitis C. We present a case of interstitial pneumonitis and pancytopenia following the combination therapy of pegylated interferon and ribavirin in a patient with chronic hepatitis C.
