Introduction: Patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV) are susceptible to opportunistic infections, including invasive fungal infections (IFI). This is due to many factors, including prolonged immunosuppressive therapy. The treatment of AAV with such IFIs is challenging.
Methods: A descriptive analysis of 5 patients with AAV complicated by concomitant invasive fungal infections was performed. We also have done a comprehensive literature review of IFIs in AAV using PubMed and Google Scholar databases.
Results: All 5 patients initially received immunosuppressive medication but subsequently acquired IFI. One patient had sphenoid sinus involvement, and four had lung parenchymal involvement. Aspergillus infection was diagnosed in three patients, Cryptococcus infection in one patient and mixed infection with Aspergillus and Mucor infection in one patient. All our patients were on low doses of corticosteroids for several months to years or had received high-dose pulse steroids with cyclophosphamide in the last few weeks before being diagnosed with IFI. It was difficult to distinguish disease activity from IFI in all the cases. Two of the five patients died despite antifungal therapy. The literature review revealed a prevalence of IFIs ranging from 1 to 9.6% (excluding pneumocystis pneumonia). Aspergillosis was the predominant type of IFI, affecting 46 of 86 patients. Most of these patients (40/46) had pulmonary involvement. The prognosis for patients with IFI was consistently poor, as evidenced by 19 deaths out of 29 reported outcomes.
Conclusion: Overall, IFIs have a poor prognosis in patients with AAV. Differentiating disease activity from IFI is difficult because of similar organ distribution, imaging lesions, and histopathological characteristics. A high suspicion index and good-quality microbiology are needed for early treatment and prevention of mortality.

Invasive infections with Aspergillus fumigatus in ICU patients are linked to high morbidity and mortality. Diagnosing invasive pulmonary aspergillosis (IPA) in non-immunosuppressed patients is difficult, as Aspergillus antigen (galactomannan [GM]) may have other causes. This retrospective study analyzed 160 ICU surgical patients with positive GM in broncho-alveolar lavage fluid (BALF), classifying them based on AspICU criteria for suspected IPA (pIPA) or aspiration.

Streptococcus pyogenes remains one of the top ten causes of mortality from infectious diseases. Children in low-income nations have high carrier rates of Streptococcus pyogenes, which can serve as a source of infections, including simple superficial infections that may lead to invasive and post-streptococcal diseases, particularly among schoolchildren. This study aimed to assess the prevalence of Streptococcus pyogenes, associated factors, and antimicrobial susceptibility profiles among urban and rural public schoolchildren in Gondar City, Northwest Ethiopia.

Incidence of Candida species increased in critically ill COVID-19 patients in intensive care units. This study aimed to investigate the impact of the COVID-19 pandemic on antifungal consumption and Candida species distribution in bloodstream infections. We observed that a significant increase in non-albicans Candida species cases (p = 0.

Background: Ulcerative colitis (UC), an inflammatory disease characterized by intestinal barrier dysfunction, poses significant challenges because of the toxicity and adverse effects commonly associated with conventional therapies. Safer and more efficacious treatment strategies are needed.
Purpose: The purpose of this study was to treat UC with Folium Artemisiae Argyi exosome-like nanovesicles (FAELNs) and to explore its related mechanism to provide a safer and more effective means for the treatment of ulcerative colitis.

Unlabelled: Early detection and intervention are crucial in managing Helicobacter pylori (HP) infections, which are associated with various gastrointestinal diseases in children. The traditional Kyoto gastritis scoring system, though effective, requires adaptation for non-invasive techniques like magnetic-controlled capsule endoscopy to enhance early diagnosis and improve patient comfort. This retrospective study involved 474 pediatric patients who underwent magnetic-controlled capsule endoscopy coupled with a C urea breath test at the Children's Hospital affiliated with Shanghai Jiao Tong University School of Medicine from January to December 2023.
