Anthrax meningoencephalitis complicated with brain abscess - A case report.

Bacillus anthracis is a sporulating gram-positive rod whose main route of entry into the human body is cutaneous. Anthrax meningitis is usually fulminant and fatal. We present here a successfully treated case of anthrax meningoencephalitis complicated with brain abscess. The patient was a shepherd, with disease onset 7 days prior to hospital admission with fever, chills, occipital headache, and vertigo, followed by right hemiplegia, motor aphasia, agitation and coma. He had cutaneous lesions with black eschar on the limbs, which was a clue (along with his occupation), for diagnosis suspicion. The polymerase chain reaction for B. anthracis DNA was positive in both cerebrospinal fluid and cutaneous lesions. The cerebrospinal fluid was compatible with bacterial meningitis without being haemorrhagic. Magnetic resonance imaging showed meningeal enhancement and multiple intraparenchymal heterogeneous lesions with an important haemorrhagic component in the left parietal lobe, surrounded by vasogenic oedema with maintenance, 22 days later, of the left parietal lobe lesion, having a ring contrast enhancement and a central diffusion restriction, compatible with an abscess. From admission, he was intensively treated with combined large-spectrum antibiotics; this could be the most valuable factor in the successful outcome.

Emergence of Toscana Virus, Romania, 2017-2018.

We describe a series of severe neuroinvasive infections caused by Toscana virus, identified by real-time reverse transcription PCR testing, in 8 hospitalized patients in Bucharest, Romania, during the summer seasons of 2017 and 2018. Of 8 patients, 5 died. Sequencing showed that the circulating virus belonged to lineage A.

Prediction of unfavorable outcomes in West Nile virus neuroinvasive infection - Result of a multinational ID-IRI study.

BACKGROUND: WNV causes 1.4% of all central nervous system infections and is the most common cause of epidemic neuro-invasive disease in humans. OBJECTIVES: Our main objective was to investigate retrospectively West Nile virus neuroinvasive disease (WNND) cases hospitalized during 2010-2017 and identified factors that can influence prognosis. STUDY DESIGN: We documented the demographic, epidemiologic, clinical and laboratory data of WNND and identified factors that can influence prognosis. The data were recruited through Infectious Diseases International Research Initiative (ID-IRI), which serves as a network for clinical researches. RESULTS: We investigated 165 patients with WNND in 10 countries from three continents. 27 patients died and the mortality rate was 16.4%. In an univariate analysis age, congestive heart failure, neoplasm and ischemic heart disease (p < 0.001), neuropsychiatric disorders (p = 0.011), chronic hepatitis (p = 0.024) and hypertension (p = 0.043) were risk factors for death. Fatal evolution was also correlated with ICU addmission, disorientation, speech disorders, change in consciousnes, coma, a low Glasgow coma score, obtundation, confusion (p < 0.001), history of syncope (p = 0.002) and history of unconsciousness (p = 0.037). In a binomial logistic regresssion analysis only age and coma remained independent prediction factors for death. We created an equation that was calculated according to age, co-morbidities and clinical manifestations that may be used to establish the prognosis of WNND patients. CONCLUSIONS: WNND remain an important factor for morbidity and mortality worldwide, evolution to death or survival with sequelae are not rare. Our study creates an equation that may be used in the future to establish the prognosis of WNND patients.

Re-emergence of severe West Nile virus neuroinvasive disease in humans in Romania, 2012 to 2017-implications for travel medicine.

BACKGROUND: In Romania, after a major outbreak in 1996, West Nile neuroinvasive disease (WNND) was reported only in a limited number of cases annually. During 2016-2017, a significant increase in the number of WNND cases was reported at the national level, associated with high mortality rates. METHODS: A retrospective analysis of all cases confirmed with WNND, hospitalized during 2012-2017 in a single tertiary facility from Bucharest was performed in order to determine the annual prevalence and mortality rate and the risk factors associated with a severe outcome. RESULTS: 47 cases were confirmed as WNND. The mortality rate was 25.5%, all death occurred during 2016-2017. Coma, confusion, obtundation, sleepiness and depressed deep tendon reflexes were symptoms predicting a severe outcome. In a univariate analysis age (p < 0.001), associated cancers (p = 0.012) and low levels of chloride in the CSF (p = 0.008) were risk factors for mortality. In a multinomial logistic analysis, age older than 75 years remained the only independent predictor of death in WNND. CONCLUSIONS: The increase in both the number and the mortality rate of WNND cases suggest a changing pattern of WNV infection in Romania. Public health authorities and clinicians should be aware of the risk of severe WNV infection in travelers returning from Romania.

First Two Imported Cases of Zika Virus Infections in Romania.

We report the first two cases of imported Zika virus (ZIKV) infection in Romanian patients returning from areas with ongoing outbreaks and challenges for laboratory diagnostic; first one with a classical pattern of acute flaviviral infection and the second one with an interesting pattern of a secondary flaviviral (ZIKV) infection in a yellow fever-vaccinated child living abroad in an endemic area.

Neurologic Complications of Influenza B Virus Infection in Adults, Romania.

We characterized influenza B virus-related neurologic manifestations in an unusually high number of hospitalized adults at a tertiary care facility in Romania during the 2014-15 influenza epidemic season. Of 32 patients with a confirmed laboratory diagnosis of influenza B virus infection, neurologic complications developed in 7 adults (median age 31 years). These complications were clinically diagnosed as confirmed encephalitis (4 patients), possible encephalitis (2 patients), and cerebellar ataxia (1 patient). Two of the patients died. Virus sequencing identified influenza virus B (Yam)-lineage clade 3, which is representative of the B/Phuket/3073/2013 strain, in 4 patients. None of the patients had been vaccinated against influenza. These results suggest that influenza B virus can cause a severe clinical course and should be considered as an etiologic factor for encephalitis.

Rickettsia massiliae infection and SENLAT syndrome in Romania.

The purpose of this prospective study is to describe the clinical and epidemiological characteristics of rickettsioses in Romania, where only Rickettsia conorii is known by clinicians but new Rickettsia species have been identified recently in ticks. A total of eight patients, including a nine-year-old child, were included between June 2011 and June 2012, in the Hospital for Infectious and Tropical Diseases, Bucharest, Romania. Seven cases presented during summer months and one in spring. Six patients presented a generalized rash with fever, myalgia and skin eschar. The last two patients presented a typical SENLAT syndrome, characterized by scalp eschar and neck lymphadenopathy. Using serological tools, we confirmed for the first time two cases of Rickettsia massiliae, the agent of spotted fever disease, and one case of Rickettsia slovaca, and one case of R. slovacaRickettsia raoultii the agents of SENLAT syndrome.
