RESUMEN

Summary: Objective.There are different diagnostic criteria for the diagnosis of Allergic bronchopulmonary aspergillosis (ABPA) in CF patients. In this present study we evaluated the prevalence of ABPA in Iranian CF patients by two more usual diagnostic criteria as ISHAM working criteria (A) and CF Foundation Consensus Conference criteria (B). Methods.Eighty-six CF patients were included in the study. All CF patients underwent for Aspergillus skin prick test (AST), Aspergillus-specific IgE (sIgEAf) and Aspergillus-specific IgG (sIgGAf), total IgE. The ABPA prevalence was estimated by two diagnostic criteria, (A) and (B) and compared. Results. The frequency of positive AST, total IgE, sIgEAf and sIgGAf were 47 (54.6%), 9 (10.5%), 42 (48.8%) and 67 (77.9%), respectively. The obtained rate of ABPA prevalence (10.5%) was identical in two diagnostic criteria A and B (kappa value of 1.000). Conclusions.The applied diagnostic criteria had no significant effect on the reported rate of ABPA prevalence.

RESUMEN

BACKGROUND: Chronic granulomatous disease is a phagocyte defect, characterised by recurrent infections in different organs due to a defect in NADPH oxidase complex. This study was performed to investigate pulmonary problems of CGD in a group of patients who underwent computed tomography (CT) scan. METHODS: Computed tomography scan was performed in 24 patients with CGD. The findings of the CT scan were documented in all of these patients. RESULTS: Areas of consolidation and scan formation were the most common findings, which were detected in 79% of the patients. Other abnormalities in order of frequencies were as follows: small pulmonary nodules (58%); mediastinal lymphadenopathy (38%); pleural thickening (25%); unilateral hilar lymphadenopathy (25%); axillary lymphadenopathy (21%); bronchiectasis (17%); abscess formation (17%); pulmonary large nodules or masses (8%); and free pleural effusion (8%). CONCLUSION: The pulmonary CT scans of the patients with CGD demonstrated a variety of respiratory abnormalities in the majority of the patients. While recurrent respiratory infections and abscesses are considered as prominent features of CGD, early diagnosis and precise check-up of the respiratory systems are needed to prevent further pulmonary complications.

RESUMEN

BACKGROUND: The similar clinical and computed tomography (CT) characteristics of cryptogenic organising pneumonia (COP) and chronic eosinophilic pneumonia (CEP) make precise diagnosis challenging. OBJECTIVES: To help differentiate between COP and CEP using high-resolution CT (HRCT). DESIGN: Clinical data and HRCT images of COP and CEP patients referred to Masih Daneshvari Hospital, Tehran, Iran, from 2007 to 2015 were reviewed. Diagnosis of COP or CEP was confirmed using open lung biopsy or a combination of transbronchial biopsy, bronchoalveolar lavage fluid (BALF) analysis, peripheral eosinophilia and a favourable response to corticosteroids. RESULTS: Ground-glass opacity, a dominant ground-glass pattern, upper-lobe pneumonia, increased thickness of bronchial walls and a mosaic pattern in the lungs were more frequent in CEP. Lower-lobe pneumonia, subpleural reticulation, a dominant consolidation pattern, nodules and masses, non-septal linear opacities, bronchial dilation and a reverse halo sign were more frequent in COP. History of asthma, wheezing and peripheral eosinophilia was significantly more common in CEP than in COP. CONCLUSION: Distinguishing between CEP and COP based on HRCT alone is not always possible. However, in many cases, especially if the correct diagnosis cannot be established by other means, certain HRCT features can be very helpful.
