    Invasive pulmonary aspergillosis evaluation in hematology patients: Three years results of tertiary hospital
    (Assoc Basic Medical Sci Federation Bosnia & Herzegovina Sarajevo, 2024) Kurc, Mine Aydin; Gunaydin, Betul; Akpinar, Seval; Safak, Birol; Kiraz, Nuri
    Invasive pulmonary aspergillosis (IPA) is the most frequent invasive fungal disease occurring in patients with hematological malignancies. Serum galactomannan (GM) antigen monitoring is thought to be helpful in the diagnosis of IPA. The aim of this study was to determine the role of a GM assay in serum samples for the diagnosis of IPA in patients with hematological disease. The data of 366 immunosuppressed patients that were hospitalized and followed up in the hematology clinic from January 2017 to December 2019 were retrospectively analyzed. The clinical and radiological findings of the patients and the GM results, requested twice a week, were evaluated. In this study, the incidence of probable and possible IPA was determined to be 15.3% (56/366). Of the cases detected, 28 (50.0%) were patients diagnosed with Acute Myeloid Leukemia (AML), and 34 (60.7%) patients who had compatible clinical and examination findings were started on antifungal treatment. Additionally, AUC (Area Under the Curve) values were calculated by ROC (Receiver Operating Characteristic) analysis, and it was determined that the diagnostic efficiency was more predictive when the cut-off was 0.5 in the GM test for IPA disease. The detection of GM antigen in serum is a very useful and rapid method for diagnosing IPA disease in immunosuppressed hematology patients. However, GM results should be evaluated together with clinical and radiological findings for early diagnosis, and the treatment approach should be determined accordingly.

    Skin infections caused by Streptococcus pyogenes after the Eid Al-Adha
    (Lippincott Williams & Wilkins, 2023) Safak, Birol; Albayrak, Hulya; Kurc, Mine Aydin; Gunaydin, Betul
    Introduction:Streptococcus pyogenes is Gram-positive bacteria in chain form. Infections typically begin in the throat and skin, although they present with a many different clinical cases. This study aimed to present a different clinical manifestation related to S. pyogenes. Methods:In this study, swab samples were taken from patients who came to our center with skin lesions after Eid al-Adha. Identification was performed using conventional methods (bacitracin susceptibility test and PYR test) and VITEK 2 (bioMerieux, Marcy l'Etoile, France). Phylogenetic tree was generated using the Tamura Nei model of Neighbor-joining method in MEGA 6.0 program. Results:All of the isolated microorganisms were defined as S. pyogenes. Phylogenetic tree revealed that strains were highly related, but there were genetic differences between the strains. Conclusion:While Orf virus (Parapoxvirus) is the most common cause of skin lesions after Eid al-Adha, S. pyogenes was found to be the causative agent in our study. To our knowledge, cases of S. pyogenes skin infection due to religious practices have been reported for the first time.
