Introduction: The aim of the study was to investigate current practice and policies of therapeutic drug monitoring (TDM) service requesting and result reporting in Czechia and Slovakia. Materials and methods: All 149 laboratories that measure plasma drug concentrations were given an online questionnaire during a regular external quality assessment TDM cycle. The questionnaire consisted of 17 questions. The optimal TDM practice was defined as the application of all elements (age, body weight, time of sampling, date of the first administration, time of the last dose administration, the dose, the dosing interval, the route of administration, information on reason of testing, and information on other co-administered drugs) needed for reporting a recommendation for further drug dosing (positive response to question number 16). Results: The response rate was 69%, 103 out of 149 laboratories measuring drug concentrations. Only 12% (12 out of 103 laboratories) of the laboratories implemented all elements needed for optimal TDM practice and reported a recommendation. Both paper and electronic request forms were used by 77 out of 103 (75%) laboratories. A total of 69 out of 103 laboratories (67%) specified the type of sampling tube on their request form. Cystatin C was used for prediction of renal drug elimination by 24% (25 out of 103) of participants. Conclusions: Small number of laboratories implemented all elements needed for optimal TDM practice and report a recommendation on further dosing. Further efforts in education on optimal TDM practice as well as harmonization of service are desirable.

Cerebral abscesses caused by dark-pigmented Fonsecaea fungi are rare, especially in otherwise healthy individuals. In this case report, we present a 61-year-old man from Moldova, living in the Czech Republic, who had worked as a locksmith on oil platforms in Turkmenistan, Kazakhstan, Sudan, and Iraq since 1999, and was admitted to a neurology ward for a sudden motion disorder of the right leg, dysarthria, and hypomimia. Imaging revealed presence of expansive focus around the left lateral ventricle of the brain and a pronounced peripheral edema. The intracranial infectious focus was excised under intraoperative SonoWand guidance. Tissue samples were histologically positive for dark-pigmented hyphae, suggesting dematiaceous fungi. Therefore, liposomal amphotericin B therapy was initiated immediately. Fonsecaea monophora was provisionally identified using ITS rDNA region sequencing directly from brain tissue. The identification was subsequently confirmed by cultivation and DNA sequencing from culture. The strain exhibited in vitro sensitive to voriconazole (MIC = 0.016 μg/mL) and resistance to amphotericin B (MIC = 4 μg/mL); therefore, the amphotericin B was replaced with voriconazole. Postoperatively, a significant clinical improvement was observed and no additional surgery was required. Based on the literature review, this is the third documented case of cerebral infection due to this pathogen in patients without underlying conditions and the first such case in Europe.
