Bacterial meningoencephalitis secondary to disseminated strongyloidiasis in a pacient with COVID-19

Introduction. Strongyloidiasis in a parasitic diseases determined by the intestinal nematode Strongyloides stercoralis. In most cases, this disease is asymptomatic, but the immunocompromised patients can develop severe forms like hyper infestation and disseminated strongyloidiasis. There severe forms of the disease are associated with bacteremias with gastrointestinal microorganisms which can determine infectious complication anywhere in the body. Bacterial meningitis is the most common complication of this kind. Case presentation. We present you the case of a 78 years old patient who initially presented in another hospital for suddenly installed aphasia. He was clinical and paraclinical evaluated and the suspected diagnosis was acute meningoencephalitis, so he was transferred in our hospital. This is a case about a patient with an immunocompromised status determined by recent infection with SARS-CoV-2 who was hospitalized and received prolonged corticosteroid therapy. The clinical examination performed at the admission shows a patient with mediocre general status, partially cooperative, partially time-spatial oriented and to one’s own person, discreet neck stiffness, anxious-depressive mood, with acute respiratory failure. A coproparasitological examination is performed which reveals the presence of filariform larvae of Strongyloides stercoralis in the stool. Also, a parasitic PCR test from a stool sample is positive for Strongyloides stercoralis. These clinical and paraclinical findings corroborated with those found in the cerebrospinal fluid examination establish the diagnosis: acute bacterial meningoencephalitis secondary to disseminated strongyloidiasis. During the disease’s evolution, he is confirmed with a new infection with SARS-CoV-2. He receives antiviral treatment, antiparasitic treatment, antibiotic treatment and symptomatic treatment. The evolution of the disease is favorable. Conclusions. The immunocompromised status of the patient determined the evolution of the infestation with Strongyloides stercoralis to a severe form complicated with acute bacterial meningoencephalitis. The difficulty in establishing the diagnosis of strongyloidiasis is represented by the fact that Romania is a non-endemic country for the infection with this parasite

COVID-19 impact on EuroTravNet infectious diseases sentinel surveillance in Europe

BACKGROUND The COVID-19 pandemic resulted in a sharp decline of post-travel patient encounters at the European sentinel surveillance network (EuroTravNet) of travellers' health. We report on the impact of COVID-19 on travel-related infectious diseases as recorded by EuroTravNet clinics. METHODS Travelers who presented between January 1, 2019 and September 30, 2021 were included. Comparisons were made between the pre-pandemic period (14 months from January 1, 2019 to February 29, 2020); and the pandemic period (19 months from March 1, 2020 to September 30, 2021). RESULTS Of the 15,124 visits to the network during the 33-month observation period, 10,941 (72%) were during the pre-pandemic period, and 4183 (28%) during the pandemic period. Average monthly visits declined from 782/month (pre-COVID-19 era) to 220/month (COVID-19 pandemic era). Among non-migrants, the top-10 countries of exposure changed after onset of the COVID-19 pandemic; destinations such as Italy and Austria, where COVID-19 exposure peaked in the first months, replaced typical travel destinations in Asia (Thailand, Indonesia, India). There was a small decline in migrant patients reported, with little change in the top countries of exposure (Bolivia, Mali). The three top diagnoses with the largest overall decreases in relative frequency were acute gastroenteritis (-5.3%), rabies post-exposure prophylaxis (-2.8%), and dengue (-2.6%). Apart from COVID-19 (which rose from 0.1% to 12.7%), the three top diagnoses with the largest overall relative frequency increase were schistosomiasis (+4.9%), strongyloidiasis (+2.7%), and latent tuberculosis (+2.4%). CONCLUSIONS A marked COVID-19 pandemic-induced decline in global travel activities is reflected in reduced travel-related infectious diseases sentinel surveillance reporting

Rickettsia massiliae infection and SENLAT syndrome in Romania

International audienceThe 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.

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

Can biomarkers of oxidative stress in serum predict disease severity in West Nile virus infection? A pilot study

West Nile virus (WNV) can cause asymptomatic infection in humans, result in self-limiting febrile illness, or lead to severe West Nile Neuroinvasive disease (WNND). We conducted a pilot study to compare selected biomarkers of oxidative stress in sera of viremic West Nile virus patients and asymptomatic infected blood donors to investigate their potential as predictors of disease severity. We found that total oxidant status was elevated in WNND and in uncomplicated WNV infections (median 9.05 (IQR 8.37 to 9.74) and 7.14 (7.03 to 7.25) µmol H(2)O(2) equiv./L, respectively) compared to asymptomatic infections (0.11 (0.07 to 0.19) µmol H(2)O(2) equiv./L) (p = 0.048). MDA levels showed a similar trend to TOS, but differences were not significant at α = 0.05. Total antioxidant status did not differ significantly between different disease severity groups. Oxidative stress appears to be associated with more severe disease in WNV-infected patients. Our preliminary findings warrant prospective studies to investigate the correlation of oxidative stress with clinical outcomes and severity of WNV infection
