    (Wiley, 2020) Dogru, Deniz; Cakir, Erkan; Sismanlar, Tugba; Cobanoglu, Nazan; Pekcan, Sevgi; Cinel, Guzin; Yalcin, Ebru
    Background Cystic fibrosis (CF) care has been implemented in Turkey for a long time; however, there had been no patient registry. For this purpose, the Turkish National CF Registry was established. We present the first results of registry using data collected in 2017. Methods The data were collected using a data-entry software system, which was accessed from the internet. Demographic and annually recorded data consisted of 15 and 79 variables, respectively. Results There were 1170 patients registered from 23 centers; the estimated coverage rate was 30%. The median age at diagnosis was 1.7 years (median current age: 7.3 years); 51 (4.6%) patients were aged over 18 years. Among 293 patients who were under 3 years of age, 240 patients (81.9%) were diagnosed through newborn screening. Meconium ileus was detected in 65 (5.5%) patients. Genotyping was performed in 978 (87.4%) patients and 246 (25.2%) patients' mutations were unidentified. The most common mutation was deltaF508 with an allelic frequency of 28%, followed by N1303K (4.9%). The median FEV1% predicted was 86. Chronic colonization with Pseudomonas aeruginosa was seen in 245 patients. The most common complication was pseudo-Bartter syndrome in 120 patients. The median age of death was 13.5 years in a total of 15 patients. Conclusions Low coverage rate, lack of genotyping, unidentified mutations, and missing data of lung functions are some of our greatest challenges. Including data of all centers and reducing missing data will provide more accurate data and help to improve the CF care in Turkey in the future.

    Severe anemia is reported to occur rarely in patients with cystic fibrosis (CF). This study aimed to determine the factors associated with early severe anemia in infants with CF. This study included 231 infants with CF from 3 pediatric CF centers ten year period that were retrospectively reviewed in terms of severe anemia as the first sign of CF. Factors that could affect anemia, such as age, pancreatic insufficiency, mutations, vitamin A and E, and albumin level were evaluated. Clinical and laboratory findings in CF patients that presented with severe anemia and no respiratory symptoms were compared to those in CF patients that did not present with severe anemia. Severe anemia as the first sign of CF was noted in 17 of 231 patients. Patient age, prolonged PT/INR and the albumin level differed significantly between the 2 groups of patients (P < 0.001). Feeding pattern, pancreatic insufficiency, vitamin E and A levels, and the types of genetic mutations did not differ between the 2 groups. The mean hemoglobin level was 5.59 +/- 0.21 g/dL and respiratory symptoms began a mean 6.3 months after diagnosis of CF in the anemia group. Conclusion: In early infancy severe anemia in the absence of respiratory symptoms can be the first sign of CF. CF should be considered in the differential diagnosis of severe anemia in infants. Anemia can occur several months before respiratory symptoms in patients with CF and may be caused due to several reasons.
