Abstract

Objective: Lower respiratory tract infections are one of the major causes of morbidity and mortality in children worldwide. Besides, epidemiological data on this subject is very limited. Mycoplasma pneumoniae is an important bacterial agent in community-acquired pneumonia (CAP) and may cause mild, moderate and severe lower respiratory tract infections. Clinical diagnosis is very difficult. Material and Methods: In this study, it was aimed to determine the seroprevalence of M. pneumoniae in children aged 0-17 years admitted to a medical faculty in Istanbul with lower respiratory tract complaints or non-respiratory findings such as cytopenia and arthritis/arthralgia and to determine the prevalence of infection among children in various age groups. One hundred and thirty-four patients were included in the present study. Venous blood and nasopharyngeal swab samples were taken from study patients. M. pneumoniae IgG and IgM antibodies were determined by ELISA (Enzyme Liquid Immunoassay) test in blood samples and M. pneumoniae Real-time polymerase chain reaction (RT-PCR) test was performed in nasopharengeal swab samples. Results: Seropositivity was seen in 50 (37.3%) patients, only specific IgM antibody positivity in 5 (3.7%) patients, both specific IgM antibody and specific IgG antibody positivity in 8 (6%) patients and 37 (27.6%) patients specific IgG antibody was also observed. The number of M. pneumoniae DNA RT-PCR positive samples was shown to be only 2 (1.5%), both of which were not serologically positive. Conclusion: Our results show a significant prevalence of M. pneumoniae in children diagnosed with acute respiratory infection. It also highlight the importance of laboratory detection for appropriate and rapid antibiotic treatment.

Özet

Giriş: Alt solunum yolu enfeksiyonları tüm dünyada çocuklarda önemli bir morbidite ve mortalite nedeni olup bu konudaki epidemiyolojik veriler oldukça sınırlıdır. Mycoplasma pneumoniae, toplum kökenli pnömonilerde (TKP) önemli bir bakteriyel bir ajandır ve hafif, orta ve ciddi alt solunum yolu enfeksiyonuna neden olabilir. Klinik olarak tanı konması oldukça zordur. Gereç ve Yöntemler: Bu çalışmada İstanbul’da bir tıp fakültesine alt solunum yolu enfeksiyonu bulguları veya sitopeni ve artrit/artralji gibi solunum dışı bulgularla başvuran 0-17 yaş arası çocuklarda M. pneumoniae seroprevalansını belirlemeyi ve çeşitli yaş gruplarındaki çocuklarda enfeksiyon prevalansının dağılımını tespit etmeyi amaçladık. Çalışmamıza 134 hasta dâhil edilmiştir. Çalışmamıza katılan hastalardan venöz kan ve nazofarengeal sürüntü örnekleri alınmış olup, kan örneklerinde M. pneumoniae IgG ve IgM antikorlarının tayini Enzim Likit immunassay (ELISA) testi; nazofarengeal sürüntü örneklerinde ise M. pneumoniae gerçek zamanlı polimeraz zincir reaksiyonu (GZ-PZR) testi gerçekleştirilmiştir. Bulgular: Toplam 50 (%37.3) hastada seropozitiflik görülmüş olup, 5 (%3.7) hastada sadece spesifik IgM antikor pozitifliği, 8 (%6) hastada hem spesifik IgM antikoru hem de spesifik IgG antikoru, 37 (%27.6) hastamızda da spesifik IgG antikoru gözlemlenmiştir. M. pneumoniae DNA GZ-PZR pozitif örnek sayımız sadece 2 (%1.5) olarak gösterilmiş olup bu hastaların ikisi de serolojik olarak pozitiflik göstermemiş hastalardır. Sonuç: Sonuçlarımız, akut solunum yolu enfeksiyonu tanısı konan çocuklarda M. pneumoniae sıklığını göstermektedir. Ayrıca uygun ve hızlı antibiyotik tedavisi için laboratuvar tespitinin önemini vurgulamaktadır
