The Presence of T Allele (rs35705950) of the MUC5B Gene Predicts Lower Baseline Forced Vital Capacity and Its Subsequent Decline in Patients with Hypersensitivity Pneumonitis.

Hypersensitivity pneumonitis (HP) is an exposure-related interstitial lung disease with two phenotypes-fibrotic and non-fibrotic. Genetic predisposition is an important factor in the disease pathogenesis and fibrosis development. Several genes are supposed to be associated with the fibrosing cascade in the lungs. One of the best-recognized and most prevalent is the common MUC5B gene promoter region polymorphism variant rs35705950. The aim of our study was to establish the frequency of the minor allele of the MUC5B gene in the population of patients with HP and to find the relationship between the MUC5B promoter region polymorphism and the development of lung fibrosis, the severity of the disease course, and the response to the treatment in patients with HP. Eighty-six consecutive patients with HP were tested for the genetic variant rs35705950 of the MUC-5B gene. Demographic, radiological, and functional parameters were collected. The relationship between the presence of the T allele and lung fibrosis, pulmonary function test parameters, and the treatment response were analyzed. The minor allele frequency in the study group was 17%, with the distribution of the genotypes GG in 69.8% of subjects and GT/TT in 30.2%. Patients with the GT/TT phenotype had significantly lower baseline forced vital capacity (FVC) and significantly more frequently had a decline in FVC with time. The prevalence of lung fibrosis in high-resolution computed tomography (HRCT) was not significantly increased in GT/TT variant carriers compared to GG ones. The patients with the T allele tended to respond worse to immunomodulatory treatment and more frequently received antifibrotic drugs. In conclusions: The frequency of MUC5B polymorphism in HP patients is high. The T allele may indicate a worse disease course, worse immunomodulatory treatment response, and earlier need for antifibrotic treatment.

Polish Female Cancer Survivors' Experiences Related to Fertility Preservation Procedures.

Purpose: The aim of the study was to assess the experience of Polish female cancer patients related to fertility preservation (FP) after gonadotoxic treatment. Methods: A cross-sectional study was performed among young women, who were diagnosed with a neoplasm. The questionnaire was distributed via the Internet. Results: The study group consisted of 299 women. Most of them had breast cancer (34%) or Hodgkin lymphoma (20%). The most popular treatment regimen was a combination of surgery, chemotherapy, and radiation (30%). Almost 78% of study participants underwent potentially gonadotoxic treatment. Fifty-seven percent of study participants admitted that oncologist had not informed them about FP methods, while only 19% were encouraged to visit fertility specialists. Seventeen percent of women decided to preserve fertility before malignancy treatment, 11.8% of women cryopreserved oocytes, 16% cryopreserved embryos, 16% cryopreserved ovarian tissue and 55% had ovarian suppression. Conclusion: The access to fertility counseling in Poland is limited. Emphasis should be placed on the coordination between cancer treatment centers and reproductive specialists.

Clinical consequences of maternal serum PAPP-A and free beta hCG levels above 2.0 multiple of median in the first trimester screening.

INTRODUCTION: Extreme levels of either PAPP-A or free ß-hCG may be a serious clinical concern. A multicentre study was carried out to determine the frequency and clinical consequences of high (minimum 2,0 MoM) maternal (PAPP)-A and free beta hCG. METHODS: A total number of 8591 patients with singleton pregnancies between 11 + 0-13 + 6 weeks of gestation were enrolled. A total number of 612 cases with first trimester serum level of PAPP-A corresponding to ≥ 2,0 MoM and/or free ß-hCG to ≥ 2,0 MoM were included in the statistical analysis. All serum samples were analysed with Roche (Cobas) or Kryptor (Brahms) devices. A retrospective analysis of perinatal outcomes was conducted. RESULTS: Values of PAPP-A ≥ 2,0 MoM and free ß-hCG < 2.0 MoM were detected in 48,5% of patients (n = 297), free ß-hCG ≥ 2,0 MoM and PAPP-A concentration < 2,0 MoM in 38,1% of patients (n = 233) and both PAPP-A and free ß-hCG ≥ 2,0 multiple of median in 13,4% of patients (n = 82). The highest PAPP-A and free ß-hCG concentrations were 19,2 MoM and 16,3 MoM respectively. Patients with both PAPP-A and free ß-hCG above 2,0 MoM had a slightly higher (but statistically not significant) prevalence of history of low birthweight (8,3%). DISCUSSION: Pregnancy outcomes in women with normal ultrasound findings and high PAPP-A /free ß-hCG concentration are good. Higher prevalence of pregnancy complications was not detected in either extremely high PAPP-A and free ß-hCG concentration groups. In cases of normal ultrasound and isolated high (even extreme) biochemical markers levels the counselling should be comforting.
