[Show abstract][Hide abstract] ABSTRACT: Background:
In Poland, lung transplantation (LTx) as a routine method began in 2004, and since then, the Silesian Center for Heart Disease in Zabrze 85 LTx has performed (54 single-lung transplantations, 30 double-lung transplantations, and 1 heart-lung) transplantation. The recommendation to take vitamin supplements (without specific indication of the iodine content) does not apply to another iodine prophylaxis in patients after lung transplantation, excluding patients with known thyroid disease. The aim of this study was to assess thyroid gland function based on hormones and urinary iodine (UI) concentration in patients after LTx.
Material and methods:
UI analysis was performed in 19 lung recipients (12 men and 7 women; mean age: 46.2 ± 12.47 years, BMI: 21 ± 2.25) and compared to TSH, free T3, and free T4.
Sufficient UI was observed only in 2 (9%) samples. In 12 samples (54.5%), mild iodine deficiency was recorded, in 4 samples (18.2%) moderate iodine deficiency was noted, and in 3 (13.6%) severe iodine deficiency was found. No correlation between BMI and UI, as well as hormones concentration, was observed. No correlation was revealed when analyzed samples were divided by patient sex.
Although thyroid gland hormones were in the normal range, we found moderate, mild, and severe iodine deficiency in the majority of analyzed samples. Measurements of urinary iodine in lung transplant recipients should accompany thyroid hormone measurements as an iodine deficiency test and in order to prevent iodine deficiency disorders.

[Show abstract][Hide abstract] ABSTRACT: This publication attempted to evaluate the frequency of mold colonization and infection and the procalcitonin serum concentrations (PCT) among lung transplant recipients.
We included 49 patients (36 males and 13 females) of mean age at transplantation of 47.1±13.6 years. Molds were isolated using routine microbiologic methods. PCT (ng/mL) was measured using an immunoluminescence assay with values below 0.5 showing no probability of infection, 0.5 to 2.0, a moderate infection risk; 2.0 to 10, a high infection risk; and above 10 high sepsis risk.
Twenty-four (49%) patients revealed the presence of molds in material from the lower respiratory tract (sputum, tracheal, or tracheobronchial aspirate), mini-bronchoalveolar lavage. Aspergillus species was isolated in 14 (28.6%) patients, Penicillium in 7 (14.3%) patients, and Zygomycetes fungi in 9 (18.4%) patients. The average PCT value from 61 examinations of PCT during fungal isolation was 0.5±0.7 ng/mL. However, when the studied group was categorized according to the PCT range, the rates for the groups were no infection (n=30; 49.2%), moderate (n=20; 32.8%), high (n=9; 14.8%) and high sepsis risk (n=2; 3.3%).
The mold colonization of transplanted lung is a frequent complication and should be considered even in the case of proper prophylaxis. Procalcitonin might be the marker helpful in mold infection diagnosis.
