Prevalence of allergic bronchopulmonary aspergillosis in cystic fibrosis patients using two different diagnostic criteria

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.

Association between left ventricular hypertrophy with retinopathy and renal dysfunction in patients with essential hypertension

INTRODUCTION

It has been suggested that hypertension (HTN) is associated with certain target organ damage (TOD) and related clinical conditions. On the other hand, left ventricular hypertrophy (LVH) has been considered as an independent risk factor of cardiovascular events and death. The aim of this study was to examine the relationship between HTN-induced LVH and TOD (retinopathy and renal failure).

METHODS

We assessed 102 hypertensive subjects (43 males and 59 females) with a mean age of 60.2 +/- 8.8 (range 35-81) years. LVH was defined as a left ventricular mass index (LVMI) of more than 51 and 47 g/(m [to the power of 2.7]), in men and women, respectively. The degree of retinopathy on ophthalmological examination was defined according to the Keith-Wagener classification. Serum creatinine, blood urea nitrogen and urine protein concentrations were also measured.

RESULTS

Hypertensive retinopathy was found in 94 (92.2 percent) cases (Grades I 55.9 percent; II 28.5 percent; III 3.9 percent; IV: 3.9 percent). The mean systolic and diastolic blood pressures and serum creatinine concentration showed significant correlation with the severity of LVH. There was no significant relationship between LVH severity and retinopathy or proteinuria.

CONCLUSION

The tight control of systolic and diastolic blood pressures in the first step of essential hypertension can assist to postpone LVH. Furthermore, routine measurement of serum creatinine can predict the risk of cardiovascular complications in the hypertensive patient.
