Abstract

Amaç:
Birkaç çalışma, düşük ortalama korpüsküler hemoglobin konsantrasyonunun (MCHC), kalp yetmezliği ve KOAH gibi kronik inflamasyonla ilişkili koşullarda mortalite ve kötü klinik seyir ile ilişkisini göstermiştir. Bu nedenle, bu çalışmada, minimum 1 yıllık takip süresi olan geniş bir hasta popülasyonunda MCHC ile yeniden yatış mortalitesi arasındaki bağlantıyı belirlemeyi amaçladık.
Yöntem:
2018 ve 2019 yılları arasında hastaneye kabul sırasındaki klinik veriler, laboratuvar verileri, kronik obstrüktif akciğer hastalığının (AECOPD) akut alevlenmesi nedeniyle acil servise başvuru sayısı, göğüs hastalıkları ünitesine yatış sayısı ve yoğun bakım yatış sayısı, çalışmaya alınan son hastanın taburcu edilmesini takiben kaydedildi. Takip süresi 12 ile 36 ay arasında değişmekteydi.
Sonuçlar:
Toplam 339 hasta dahil edildi. MCHC için eşik değeri 32.35 g/dl olarak bulundu. Bu cut-off değerine göre klinik verilerin karşılaştırılması yapıldı. 1 yıllık süre içinde başvuru sırasında pnömoni, hiperkapnik solunum yetmezliği, non-invaziv mekanik ventilasyon (NIV) ihtiyacı ve yoğun bakıma yatış sayısında artış olduğu gösterildi. Ayrıca MCHC ≤ 32.35 g/dL olan ve anemik olmayan kişilerde sağkalımın azaldığı gösterildi. Artan mortalite ile ilişkili faktörler arasında ileri yaş, demans varlığı, karaciğer yetmezliği, 1 yıl içinde KOAH alevlenmesine bağlı daha fazla acil servis başvurusu, daha fazla yoğun bakım ünitesi başvurusu ve başvuru sırasında NIV ihtiyacı olması vardı. Öte yandan, kabul sırasında elde edilen MCHC değeri, mortalite riskinin bağımsız bir öngördürücüsü değildi.
Sonuç: Düşük MCHC'li ancak anemisi olmayan AECOPD hastalarında diğer komorbiditelerin dikkatli bir şekilde izlenmesini ve değerlendirilmesini öneriyoruz. MCHC, mortalitenin bağımsız bir öngördürücüsü olarak bulunmadı, ancak anemisi olmayan hastalarda MCHC ile sağkalım arasında anlamlı bir ilişki saptandı.

Abstract

Background and Aim:
Several studies have shown associations of low mean corpuscular hemoglobin concentration (MCHC) with mortality and poor clinical course in conditions associated with chronic inflammation such as cardiac failure and COPD. Thus, in this study we aimed to determine the link between MCHC and readmission mortality in a large patient population with minimum 1 year of follow-up.
Methods:
Clinical data at admission, laboratory data, number of admissions to emergency room due to acute exacerbation of chronic obstructive pulmonary disease (AECOPD) following the discharge of the last patient recruited, number of admissions to pulmonology unit, and number of intensive care unit admissions between 2018 and 2019 were recorded. The follow-up duration ranged between 12 and 36 months.
Results:
A total of 339 patients were included. Based on a ROC analysis, the cut-off value for MCHC was 32.35 g/dl. Comparison of clinical data according to this cut-off value showed an increase in the incidence of pneumonia during admission, hypercapnic respiratory failure, need for non-invasive mechanical ventilation (NIV), and number of intensive care unit admissions within a 1 year period, as well as reduced survival in non-anemic subjects with MCHC ≤ 32.35 g/dL. In multivariate cox-regression analysis MCHC was not an independent predictor of mortality risk.
Conclusion: We recommend careful monitoring and assessment of comorbidities in AECOPD patients with low MCHC but without anemia. MCHC was not found to be an independent predictor of mortality but there was a significant correlation between MCHC and survival in patients without anemia.
