Seltene Ursache eines Lungentumors – Fallbericht einer pulmonalen Infektion mit Hafnia alvei

ZusammenfassungBei Verdacht auf maligne Erkrankung ist die rasche Abklärung tumorverdächtiger pulmonaler Raumforderungen geboten. Im vorgestellten Fall gelang mehrmals kein Nachweis von Malignität. Erst die testgerechte antibiotische Behandlung eines inital als Verunreinigung gewerteten Darmkeimes brachte den Therapieerfolg mit Totalremission. Hierbei war die Behandlung mit dem Breitspektrumpenicillin Piperacillin/Tazobactam ineffektiv und erst die Gyrasehemmer Ciprofloxacin bzw. Levofloxacin brachten den Therapieerfolg.

Specific Strains of Honeybee Gut Lactobacillus Stimulate Host Immune System to Protect against Pathogenic Hafnia alvei

Honeybees are essential pollinators supporting global agricultural economies and food supplies. Recent honeybee decline has been linked to several factors, while pathogen infection is considered one of the most significant contributing factors.

Hafnia alvei Pneumonia: A Rare Cause of Infection in a Patient with COVID-19

Herein, we describe a case report of a critically ill patient, a 48-year-old man without comorbidities admitted to the hospital with a serious type 1 (hypoxemic) respiratory insufficiency and confirmed diagnosis of COVID-19. After 5 days with invasive mechanical ventilation, the patient developed a bacterial co-infection, namely a pneumonia by Hafnia alvei, requiring the last line of respiratory support: extracorporeal membrane oxygenation (ECMO). Subsequently, his clinical situation gradually stabilized, until he was discharged from the hospital on day 61, being accompanied in ambulatory consultation by the physical medicine and pulmonology department during the post-COVID-19 recovery. H. alvei is a Gram-negative bacterium that is rarely isolated from human specimens and is rarely considered to be pathogenic. However, COVID-19 disease can cause substantial organ dysfunction and can be associated with bacterial secondary infections which can favor the emergence of rare infectious diseases by uncommon microorganisms.
