Herpes simplex encephalitis is a rare disease with significant morbidity and mortality, although targeted therapy is widely available. This report presents two cases of herpes simplex encephalitis in previously healthy, young adults treated with acyclovir, who developed severe brain edema. Decompressive craniectomy prevented imminent brain herniation and a fatal outcome in both of these patients.
West Nile Virus Neuroinvasive Disease (WNV NID) requires prolonged intensive care treatment, resulting in high mortality and early disability. Long-term results are lacking. We have conducted an observational retrospective study with a prospective follow-up of WNV NID patients treated at the Intensive Care Unit (ICU), University Hospital for Infectious Diseases, Zagreb, Croatia, 2013–2018. Short-term outcomes were vital status, length of stay (LOS), modified Rankin Scale (mRS), and disposition at discharge. Long-term outcomes were vital status and mRS at follow-up. Twenty-three patients were identified, 78.3% males, median age 72 (range 33–84) years. Two patients (8.7%) died in the ICU, with no lethal outcomes after ICU discharge. The median ICU LOS was 19 days (range 5–73), and the median hospital LOS was 34 days (range 7–97). At discharge, 15 (65.2%) patients had moderate to severe/mRS 3–5, 6 (26.0%) had slight disability/mRS 2–1, no patients were symptom-free/mRS 0. Ten (47.6%) survivors were discharged to rehabilitation facilities. The median time to follow-up was nine months (range 6–69). At follow-up, seven patients died (30.5%), five (21.7%) had moderate to severe/mRS 3–5, one (4.3%) had slight disability/mRS 2–1, six (26.1%) had no symptoms/mRS 0, and four (17.4%) were lost to follow-up. Briefly, ten (43.5%) survivors improved their functional status, one (4.3%) was unaltered, and one (4.3%) aggravated. In patients with severe WNV NID, intensive treatment in the acute phase followed by inpatient rehabilitation resulted in significant recovery of functional status after several months.
Capnocytophaga canimorsus is a rare cause of disease in humans. This article reports a case of C. canimorsus meningitis in an adult previously immunocompetent woman but with concurrent influenza A infection. The diagnosis was made from a blood and cerebrospinal fluid culture using DNA sequencing, and the patient recovered well after a 21-day course of ceftriaxone. Based on our case report and other available literature on the subject, implications of exposure history, empirical bacterial meningitis treatment, and dog bite prevention are discussed.
Aim To compare the outpatient treatment of community acquired pneumonia (CAP) by infectious disease doctors (IDDs) and doctors of other specialties (nIDDs). Methods We retrospectively identified 600 outpatients with CAP: 300 treated by IDDs and 300 by nIDDs in two tertiary hospitals during 2019. The two groups were compared in terms of adherence to guidelines, antibiotic group prescription, frequency of combined treatment, and treatment duration. Results IDDs prescribed significantly more first-line treatment ( P < 0.001) and alternative treatment ( P = 0.008). NIDDs prescribed more reasonable ( P < 0.001) and unnecessary ( P = 0.002) second-line treatment, and inadequate treatment ( P = 0.004). IDDs significantly more frequently prescribed amoxicillin ( P < 0.001) for typical and doxycycline ( P = 0.045) for atypical CAP, while nIDDs significantly more frequently prescribed amoxicillin-clavulanate ( P < 0.001) for typical and fluoroquinolones for both typical ( P < 0.001) and atypical ( P < 0.001) CAP. No significant differences were found in the frequency of combined treatment, which exceeded 50% in both groups, or in treatment duration. Conclusions Outpatient treatment of CAP in the absence of IDDs meant more broad-spectrum antibiotic prescription and more disregard for national guidelines. Our results highlight the need for antibiotic stewardship, especially in settings with no IDDs.
BackgroundEncephalitis is a heterogeneous syndrome associated with significant mortality and neurophysiological sequelae. The etiology is identified in only 20–50% of cases, and long-term outcomes of survivors are underinvestigated, especially in patients with unknown etiology. The aim of this study was to describe long-term outcomes of patients with aseptic encephalitis of various etiologies.MethodsThe study population consisted of a retrospectively identified cohort of consecutive adult patients diagnosed with viral and etiologically undiagnosed encephalitis during a 24-month period (2014-2015) at the University Hospital for Infectious Diseases Zagreb, Croatia. Clinical, laboratory data and short-term outcomes were collected from medical records, and long-term outcomes were assessed by telephone interviews and quantified through modified Rankin scores (mRS).ResultsA total of 90 patients were identified (57.7% female; 51.5 ± 17.4 years). Viral etiology was identified in 20 (22.2%) patients: herpes simplex virus (HSV-1, 8.9%), varicella-zoster virus (VZV, 6.7%), Tick-borne encephalitis (TBE, 4.4%) and enteroviruses (2.2%). Postinfectious meningoencephalitis was suspected in 14 (15.6%) patients, and 56 (62.2%) had unknown etiology. Elevated CSF WBC was present in 77 patients (mean of 169.3 ± 279.4/mm3) and all but 6 had elevated CSF proteins (1.23 ± 0.88 g/L). Convulsions occurred more frequently in HSV-1 (37.5%) and in unknown etiology group (15.7%). GOS<3 was noted in 50% of HSV, 33% of VZV, 25% of TBE and 24% of unknown group patients during hospitalization. Mechanical ventilation was necessary in 17.1% of patients with unknown and 23.5% with viral etiology for the mean duration of 1.8 ± 6.7 and 3.2 ± 6.3 days, respectively. The mean length of stay was 23.2 ± 18.5 days. In-hospital mortality was 7.8%. Among 64 survivors who were available for follow-up interviews (mean follow-up of 28.6 ± 6.8 months), 73.1% with unknown and 90.9% with viral etiology had favorable outcomes (mRS 0–1); 4 (6.25%) had moderate (mRS 3) and 3 (4.6%) had severe neuropsychological deficits (mRS 4-5).ConclusionAlthough the etiology of aseptic encephalitis is often unknown, long-term outcomes are favorable in the majority of patients.Disclosures All authors: No reported disclosures.
