Efficacy of adalimumab therapy in experimental rat sclerosing encapsulated peritonitis model.

AIM: To investigate the efficacy of adalimumab treatment in an experimental rat sclerosing encapsulated peritonitis (SEP) model. METHODS: The study involved 40 Wistar albino rats divided into four groups: chlorhexidine (CH) group, control group, CH + adalimumab group, and CH + resting group. The control group received normal saline intraperitoneally (i.p.). Other groups received 0.1% CH gluconate, 15% ethanol, and normal saline mixture i.p. for three weeks in order to induce SEP. CH + adalimumab group received 5 mg/kg adalimumab i.p. at the beginning of week 4 and week 6, while CH + resting group was followed-up for three weeks without applying any procedure after the onset of SEP. Rats in groups CH and control group were sacrificed on day 21, and rats in group CH + adalimumab and CH + resting were sacrificed on day 42. All groups were evaluated for peritoneal thickness, inflammation, vascularization, and fibrosis. RESULTS: CH + adalimumab group showed a significant decrease in peritoneal thickness, fibrosis score, and vascular score compared with CH group and CH + resting group. CONCLUSION: Adalimumab can prevent SEP development.

Aspergillus Endogenous Endophthalmitis as a Clue to Identifying a Delayed Lumbosacral Osteomyelitis.

PURPOSE: To present a case of aspergillus-induced endogenous endophthalmitis evolving into delayed lumbosacral osteomyelitis, initially misdiagnosed as ankylosing spondylitis (AS) in an immunocompetent patient. METHOD: Case Report. RESULTS: A 38-year-old woman, initially treated for pneumonia, experienced sudden loss of vision in her left eye, prompting a thorough examination that revealed a distinct chorioretinal infiltrate. Microbiological analysis of the patient's vitreous samples detected Aspergillus fumigatus, leading to the diagnosis of endogenous endophthalmitis. Treatment involved vitrectomy, intravitreal injections, and intravenous amphotericin B. Two months later, she was referred for lower back pain, misdiagnosed as AS. Lumbosacral biopsy confirmed Aspergillus involvement once more, necessitating antifungal therapy. CONCLUSION: This case highlights the atypical progression of Aspergillus-induced endogenous endophthalmitis to delayed lumbosacral osteomyelitis in an immunocompetent individual. It highlights the crucial role of a meticulous medical history examination and interdisciplinary collaboration in diagnosing and managing diseases, especially in cases with atypical presentations.
