In addition, mortality is substantial among bacteremic patients with respiratory conditions or other chronic debilities, especially when respiratory copathogens are present. [ncbi.nlm.nih.gov]

• Fever of Unknown Origin

  A case of bacterial endocarditis caused by Moraxella catarrhalis in an apparently immunocompetent Greek male is presented, which was diagnosed after a 2-month history of low-grade fever of unknown origin. [ncbi.nlm.nih.gov]

• Regurgitation

  During antibiotic treatment, fever and infectious parameters disappeared, but severe aortic regurgitation developed. Aortic valve replacement was performed, during which extensive destruction of the aortic valve was noted. [ncbi.nlm.nih.gov]

Diagnostic workup as per BTS guidelines helped in finding the etiologies which lead to change in the patient management. [cureus.com]

Bacteremia due to this organism therefore requires prompt treatment, as serious organ complications, including endocarditis, can occur. [ncbi.nlm.nih.gov]

Treatments for Moraxella Catarrhalis: In this section, we will know about some of the treatment for Moraxella Catarrhalis. [epainassist.com]

The ESR was 2 mm/1st h and CRP was 20.5 mg/l after the end of treatment. [ard.bmj.com]

The prognosis is good for febrile neutropenic patients with underlying leukemia or lymphoma when the neutropenia resolves. [ncbi.nlm.nih.gov]

Prognosis among the immunocompromised, those with underlying lung disease, those in hospital, the elderly and the very young is variable but tends to be worse. [patient.info]

It is noted that the prognosis for Moraxella Catarrhalis is pretty good if the infection is detected early. Usually with 5-7 days of antibiotic treatment, the infection clears off. [epainassist.com]

Multibacterial etiology was seen in 34 (38%) samples, and M. catarrhalis was detected in most (85%) of those cases. Fifteen signals for M. catarrhalis were strong, suggesting a highly probable etiological role of the pathogen. [ncbi.nlm.nih.gov]

To our knowledge, Moraxella species have been reported as the etiologic agent in three cases [jamanetwork.com]

The case presented suggests the pathophysiology of this rare condition. One previous case of septic arthritis caused by M. catarrhalis without documented bacteremia has been reported. [ncbi.nlm.nih.gov]

Pathophysiology and Etiology Studies have shown that M catarrhalis colonizes the upper respiratory tract in 28-100% of humans in the first year of life. In adults, the colonization rate is 1-10.4%. [emedicine.medscape.com]

A vaccine to prevent M. catarrhalis infections would have an enormous impact globally in preventing morbidity caused by M. catarrhalis in these populations. [ncbi.nlm.nih.gov]
