Colistin Methanesulfonate

ABSTRACTColistin pharmacokinetics were prospectively studied after intravenous administration of colistin methanesulphonate in critically ill patients without central nervous system infection (controls,n= 5) and in patients with external ventricular drain-associated ventriculitis after intravenous administration (EVDViv,n= 3) or combined intravenous/intraventricular administration (EVDVcomb,n= 4). Cerebrospinal fluid (CSF)/serum colistin concentration ratios were higher in EVDViv than in control patients (11% versus 7%,P≤ 0.05) and in EVDVcomb compared to all other patients (P< 0.0001). CSF colistin concentrations above the MIC of 0.5 μg/ml were achieved only in EVDVcomb patients.

Active Hemorrhage

Critically ill patients commonly present with anemia, defined as a hemoglobin level less than 13.0 g/dL in men and less than 11.6 g/dL in women or as clinical signs of bleeding, including tachycardia and low urine output with active hemorrhage. Anemia is common, occurring in up to a third of critically ill patients, and is associated with high morbidity and mortality rates, particularly in patients with central nervous system injuries and disease. The causes of anemia can vary from chronic conditions such as kidney disease or malnutrition to acute conditions such as bleeding or consumptive coagulopathy.

AbstractStatus epilepticus is associated with high morbidity and mortality, often requiring multiple drug interventions and intensive care monitoring. Etiology of status epilepticus plays a crucial role in the treatment, natural course and outcome of the patient, prompting extensive testing and imaging. For example, an important risk for status epilepticus in adults and children is the presence of an underlying viral or bacterial central nervous system infection, appropriate treatment of which can improve the outcome of the patient. We present three cases of new-onset refractory status epilepticus in women who did not have evidence of a central nervous system infection and had significantly elevated leukocytes compared to protein in the cerebrospinal fluid. This finding suggests an autoimmune etiology; however, standard autoimmune testing was unremarkable in all cases. This case series highlights the variability in presentation and clinical course in patients presenting with status epilepticus of unknown cause, and we discuss the importance of further research into appropriate and reliable diagnostic evaluations.

Review Of Literature

Presence of bone marrow elements in cerebrospinal fluid is rare. Journal publications on this topic are few and majority of them were written over a decade ago mostly as case reports in young children or the elderly. The increased cellularity and presence of myeloid precursors can be a pitfall and may be misdiagnosed as leukemia or lymphoma or central nervous system infection, when the specimen is actually not representative. With the intention to create awareness of potential pitfalls and avoid erroneous diagnoses, as well as adding on to the current photo archive of bone marrow elements in CSF, we present a recent case of bone marrow contaminants in the CSF of a 16-year-old girl.

(1-3)-β-d-Glucan (BDG) from cerebrospinal fluid (CSF) is a promising marker for diagnostic and prognostic aid of central nervous system (CNS) fungal infection, but its relationship to serum values has not been studied. Herein, we detected BDG from CSF at levels 2-fold lower than those in serum in patients without evidence of fungal disease but 25-fold higher than those in in serum in noncryptococcal CNS fungal infections. CSF BDG may be a useful biomarker in the evaluation of fungal CNS disease.

Background: Generally, about half of the patients with central nervous system infections cases remain unexplained. Therefore, we aimed to describe which viruses were detected in unselected patients with a suspected central nervous system infection and the first diagnostic workflow in a university hospital laboratory. Methods: A comprehensive virus testing in cerebrospinal fluid with an in-house real-time PCR method was employed. Determining how many and which viruses to test was at the full discretion of the treating physician. Results: 1462 patients were evaluated from 2011 to 2017 and 9 898 viral PCRs were made: 176 subjects (12%) had a positive result. There was great heterogeneity in the frequency of patients tested for each virus, ranging from 97.9% (1431 out of 1462) for herpes simplex virus (HSV) to 1.9% (28 out of 1462) for Parvovirus B19, positive in 1 patient. Enterovirus (EV) was the leading virus detected: the frequency was higher with respect to HSV (5.2% vs 2.4%, p=0.0004), varicella-zoster virus (VZV)(5.2% vs 2.9%, p=0.0052), human herpesvirus-6 (5.2% vs 1.7%, p=0.0014) and human herpesvirus-7 (HHV-7)(5.2% vs 2.5%, p=0.0406). Both VZV (83.5%) and HSV (97.9%) were tested significantly more than EV (68.7%, p<0.0001) and HHV-7 (24.1%, p<0.0001): the latter had a positivity comparable to HSV and it was detected in younger patients (median age 29 years), as for EV (median age 35 years). There was no difference found in the age of positive subjects with respect to negative ones for the other viruses tested. Conclusion: EV was the fifth virus frequently included in the diagnostic workflow but the most frequently detected, mostly in subjects aged less 40, as HHV-7 was. Testing these two viruses in all younger patients could reduce the number of unknown etiology.
