RESUMO
Background: The effectiveness, safety, and cost of vancomycin and linezolid for managing gram-positive bacterial infections in Kuwait are unknown. This study assessed the effectiveness, safety, and cost of vancomycin, teicoplanin and linezolid for managing gram-positive bacterial infections in Kuwait. Research design and methods: This retrospective study included adult patients who were prescribed antibiotics (vancomycin, teicoplanin, and linezolid) for the treatment of gram-positive infections at five hospitals in Kuwait. Descriptive statistics were used to assess the effectiveness and safety outcomes. A cost analysis was performed on the patients hospitalised for gram-positive infections. Results: Among 116 patients, 42.2 % (n = 49) received glycopeptides (vancomycin [n = 45] and teicoplanin [n = 4]) or linezolid (n = 67). Clinical cure was achieved in 100 patients without significant intergroup differences (p = 0.34). Thrombocytopenia and acute kidney injury occurred in 19 and 20 patients (p = 0.82 and 0.96), respectively, and their incidence was similar with all the studied agents. The average cost per patient was USD 983.70. The estimated total direct medical costs were USD 894,570.6, the cost was highest for linezolid (USD 469,682.30) and vancomycin (USD 370,342.5), and lowest for teicoplanin (USD 20,799.9). Conclusions: Glycopeptides and linezolid were highly effective. Linezolid was the most frequently prescribed agent; its effectiveness and safety were similar according to the antibiotic class. However, treatment with linezolid and vancomycin were associated with considerable costs.
RESUMO
A case of allergic fungal sinusitis (AFS) caused by Exserohilum rostratum, proven by culture and histopathology of the biopsy material, is described. The identity of the isolate was confirmed by sequencing of ITS region of rDNA. To the best of our knowledge, this is the first report of allergic E. rostratum sinusitis from Kuwait and Arabian Peninsula. Ten previously described cases of AFS have been reviewed. The report highlights the emerging importance of E. rostratum as a human pathogen in this region and role of molecular methods in its accurate identification.
