Abstract

Introduction: Influenza subtypes vary by clinical, radiological, and prognostic courses and may go along with viral pneumonia. Weaimed to identify clinical, radiological, and prognostic aspects of influenza epidemic during years 2016-2017.Materials and Methods: Influenza cases reported to the Public Health Directorate in our city was assessed retrospectively. Clinical,radiological, and prognostic parameters were compared based on influenza subtypes.Results: We analyzed samples from 197 cases with suspected influenza. Mean age of the subjects was 51.17 ± 26.74. We foundinfluenza A/H1N1, influenza A/H3N2, and influenza B in 59 (30.0%), 29 (14.7%), and 3 (1.5%) cases, respectively. Comorbiditywas present in 48 (24.4%) cases. Most common radiological finding was interstitial pattern. Seventy-one and 79 per cent of H1N1and H3N2 cases were influenza pneumonia, respectively. The prevalence of overall mortality was 5.5% with a predominance inH1N1 over H3N2. Influenza vaccination had been performed in 6.8% and 3.4% of H1N1 and H3N2 cases, respectively. Wedetected no mortality in any vaccinated patient. We identified 6 pregnant women, 2 of which ended up with preterm birth, andanother one with abortion.Conclusion: Often manifested as lower respiratory tract infection, influenza may cause epidemics with increased mortality rate.Influenza should be suspected when interstitial pattern was seenon radiological images. H1N1 cases course worse. Since the prognosis is better in vaccinated patients, seasonal influenza vaccination among the community needs to be elevated. In addition,protective measures like vaccination should be taken in pregnancyto avoid preterm delivery or abortion.

Özet

Giriş: İnfluenza subtiplerine göre farklı klinik, radyolojik ve prognostic seyir gösterebilir ve viral pnömoni ile seyredebilir. Amacımız, 2016-2017 yılları influenza salgınını subtiplerine göre klinik, radyolojik ve prognostic olarak incelemekti. Materyal ve Metod: İlimizde halk sağlığı müdürlüğüne bildirilen olgular retrospektif olarak incelenmiştir. Klinik, radyolojik ve prognostik parametreler influenza subtiplerine göre istatistiksel olarak karşılaştırılmıştır. Bulgular: İnfluenza şüphesi ile 197 olgudan örnek gönderilmişti. Yaşları 51.17 ± 26.74 idi. Olguların 59 (%29.9)’unda influenza A/H1N1, 29 (%14.7)’unda influenza A/H3N2, 3 (%1.5)’ünde influenza B mevcuttu. Kırk sekiz (%24.4) olguda ek hastalık vardı. Mikronodüler görünüm en sık radyolojik bulguydu. H1N1 olgularının %71’i, H3N2 olgularının %79’u influenza pnömonisiydi. Mortalite %5.5’di ve H1N1 olgularında H3N2’ye göre daha fazlaydı. H1N1 olgularının %6.8’i, H3N2 olgularının %3.4’ü influenza aşısı yaptırmıştı. Aşı yaptıranların hiçbirinde mortalite gözlenmedi. Altı gebe olgumuz mevcuttu ve gebeliğin 2’si erken doğum, 1’i abortusla sonlandı. Sonuç: İnfluenza, sıklıkla alt solunum yolu hastalığı olarak seyreden, mortalite oranı yüksek salgınlara neden olabilen bir etkendir. Radyolojik olarak mikronodüler görünüm saptandığında influenzadan şüphelenilmelidir. H1N1 olguları daha kötü seyirlidir. Aşı yaptıranlarda prognoz daha iyi seyrettiği için, toplumda mevsimsel influenza aşılaması arttırılmalıdır. Gebelikte erken doğum ve abortusla seyredebileceğinden aşılama vb. koruyucu önlemler alınmalıdır.
