We report an unusual and confirmed case of invasive amebiasis in a non-endemic area where the source of infection remains unknown. During her admission, the patient developed amebic colitis and ...extraintestinal liver abscess with a favorable outcome following the antiparasitic therapy.
The human immunodeficiency virus (HIV) type 1 Tat protein plays a key role in the life cycle of the virus and in pathogenesis and is highly conserved among HIV subtypes. On the basis of this and of ...safety, immunogenicity, and efficacy findings in monkeys, Tat is being tested as a vaccine in phase 1 trials. Here, we evaluated the incidence and risk of progression to advanced HIV disease by anti-Tat serostatus in a cohort of 252 HIV-1 seroconverters. The risk of progression was lower in the anti-Tat–positive subjects than in the anti-Tat–negative subjects. Progression was faster in the persistently anti-Tat–negative subjects than in the transiently anti-Tat–positive subjects, and no progression was observed in the persistently anti-Tat–positive subjects
Schistosomiasis is a neglected parasitic disease linked to water, posing a global public health concern with a significant burden in sub-Saharan Africa. It is transmitted by
spp., causing both acute ...and chronic effects affecting the urogenital or the hepato-intestinal system. Through granuloma formation, chronic schistosomiasis weakens host immunity, heightening susceptibility to coinfections. Notably, female genital schistosomiasis (FGS), a disregarded gynecological condition, adversely affects girls' and women's reproductive health and increases vulnerability to HIV. This review explores the intricate interplay between schistosomiasis and HIV, considering their geographical overlap. We delve into the clinical features of this coinfection, underlying mutual influences on transmission, diagnostic challenges, and therapeutic approaches. Understanding the dynamics of FGS and HIV coinfection is pivotal for integrated healthcare strategies in regions with co-endemicity, aiming to mitigate the impact of the two infections on vulnerable populations.
Floods, and cyclones are occurring with increasing frequency and intensity worldwide due to global warming. Mozambique is very susceptible to these extreme events due to its geographical location. In ...the last ten years, four of the most severe extreme climatic events have been observed in this country, leading to widespread destruction of infrastructure and the displacement of inhabitants. Cyclones Dineo in 2017, Idai and Kenneth in 2019 and recently Freddy in 2023 affected in total over two million people impacting food and water security, causing cholera outbreaks and damage to health facilities. The mobile health units, known as Brigadas Móveis (BM), are crucial to the Mozambican health system as they provide people in the most remote areas with vaccinations, and antimalarials, and other interventions. The BM activities in five districts of Inhambane province in the south of Mozambique are run by the NGO Medicus Mundi Italia in collaboration with the local health authorities. Cyclone Freddy flooded the province of Inhambane, affecting road accessibility and the BM’s planned operations in all five districts with a loss of 37.8% of BM outreach activities. The temporary absence of the BM service resulted in rural communities having no access to health care, including routine vaccine administration. Adaptation strategies need to be implemented to address the healthcare challenges associated with extreme climate events. As described in our experience in Inhambane, BM restored outreach activities immediately after the cyclone, improving access to care after challenging situations.
COVID-19 pandemic is requesting unprecedented efforts by health-care workers (HCWs) in all countries, and especially in Italy during the first semester of 2020.
This is a retrospective, observational ...study conducted at the Spedali Civili General Hospital, in Brescia, Northern Italy during the SARS CoV-2 pandemic in the first semester of 2020. Serum samples from HCWs were tested for SARS-CoV-2 spike protein-specific antibodies. An online survey was used to collect demographic, clinical, and epidemiological data.
Of the 1893 HCWs included, 433 (22.9%) were found seropositive for SARS-CoV-2 IgG. The cumulative prevalence of SARS-CoV-2 infection (antibodies production or past positive RT-PCR on nasal/throat swab) was 25.1% (475/1893). Fifty-six out of 433 (13%) seropositive participants declared to have been asymptomatic during the study period. The development of COVID-19 signs or symptoms is the main determinant of seropositivity (OR: 11.3,
< 0.0001) along with their duration and severity. 40/290 (14.5%) HCWs with documented positive RT-PCR during the study period did not show any detectable antibody response. IgG levels positively correlate with age, COVID-19-compatible signs and symptoms experienced and their duration.
In this study, carried out in one of the most affected areas in Europe, we demonstrate that most HCWs with COVID-19 related symptoms develop a spike protein-specific antibodies with potential neutralizing effect.
A hyperinflammatory syndrome (HIS) may cause a life-threatening acute respiratory distress syndrome (ARDS) in patients with COVID-19 pneumonia.
A prospective series of 100 consecutive patients ...admitted to the Spedali Civili University Hospital in Brescia (Italy) between March 9th and March 20th with confirmed COVID-19 pneumonia and ARDS requiring ventilatory support was analyzed to determine whether intravenous administration of tocilizumab (TCZ), a monoclonal antibody that targets the interleukin 6 (IL-6) receptor, was associated with improved outcome. Tocilizumab was administered at a dosage of 8 mg/kg by two consecutive intravenous infusions 12 h apart. A third infusion was optional based on clinical response.
The outcome measure was an improvement in acute respiratory failure assessed by means of the Brescia COVID Respiratory Severity Score (BCRSS 0 to 8, with higher scores indicating higher severity) at 24–72 h and 10 days after tocilizumab administration.
Out of 100 treated patients (88 M, 12 F; median age: 62 years), 43 received TCZ in the intensive care unit (ICU), while 57 in the general ward as no ICU beds were available. Of these 57 patients, 37 (65%) improved and suspended noninvasive ventilation (NIV) (median BCRSS: 1 IQR 0–2), 7 (12%) patients remained stable in NIV, and 13 (23%) patients worsened (10 died, 3 were admitted to ICU). Of the 43 patients treated in the ICU, 32 (74%) improved (17 of them were taken off the ventilator and were discharged to the ward), 1 (2%) remained stable (BCRSS: 5) and 10 (24%) died (all of them had BCRSS≥7 before TCZ). Overall at 10 days, the respiratory condition was improved or stabilized in 77 (77%) patients, of whom 61 showed a significant clearing of diffuse bilateral opacities on chest x-ray and 15 were discharged from the hospital. Respiratory condition worsened in 23 (23%) patients, of whom 20 (20%) died.
All the patients presented with lymphopenia and high levels of C-reactive protein (CRP), fibrinogen, ferritin and IL-6 indicating a HIS. During the 10-day follow-up, three cases of severe adverse events were recorded: two patients developed septic shock and died, one had gastrointestinal perforation requiring urgent surgery and was alive at day 10.
In conclusion, our series showed that COVID-19 pneumonia with ARDS was characterized by HIS. The response to TCZ was rapid, sustained, and associated with significant clinical improvement.
The aim of the article is to review the most recent evidence concerning parasitic skin infections.
Parasitic skin infections are increasingly reported worldwide. Special at-risk categories are ...migrants, returning travelers, and immunocompromised individuals, who are at higher risk to present disseminated disease. The number of reported cases is growing even outside the endemic areas as a consequence of international travels, migration flows, increasing immunocompromised population, climate change, and natural disasters.
Skin parasitoses are neglected infections. Funding assigned to prevent and treat them is limited, even if they affect millions of persons worldwide. Diagnosis could be a challenge for clinicians of high-income countries who are facing an increasing number of such infections related to great epidemiological events.
Various studies have ascertained different birth outcomes between resident and migrant populations in western countries. Considering preterm delivery (<37 complete weeks of gestation) as a perinatal ...risk condition, we assessed its rate in migrant and native Italian women who delivered in the main public hospital in Brescia (Italy).
All migrant puerperas and a random sample of native puerperas hospitalized during the period February to May 2005 were included in the study after informed consent and filled in a self-administered multilanguage questionnaire enquiring about sociodemographic and obstetric data. Additional information including last menstrual period was obtained from personal obstetric records.
As many as 471 puerperas entered the study: 366 Italian and 105 migrant women coming from eastern Europe (41.9%), Asia (20%), South America (10.5%), and Africa (27.6%). Of the migrant population, 67 of 105 (63.8%) were at their first delivery in Italy (median interval from arrival: 3.8 y). Gestational age at delivery was assessed for 456 of 471 women (103 migrants and 353 Italians). A total of 36 (7.9%) preterm deliveries were registered: 22 (6.2%) in Italian and 14 (13.6%) in migrant puerperas (p value = 0.015). The highest preterm delivery rate was observed in African women (20.7%), while women from eastern Europe had a similar rate to Italians. In univariate analysis, factors associated to preterm delivery were parity and length of permanence in Italy. We could not demonstrate any correlation with smoking or with a delayed access to antenatal care (first obstetric evaluation after 12 complete weeks of gestation). In multivariate analysis, African origin was the only independent risk factor for preterm delivery odds ratio (OR) = 3.54; p = 0.018.
In our setting, preterm delivery occurred more frequently in migrant women, particularly of African origin, and it is not associated to delayed access to antenatal care.
Before 2022, monkeypox virus (Mpox) infection in humans was seldom reported outside Africa. During the May 2022 outbreak, most cases were detected among men who have sex with men (MSM). Since Mpox is ...largely unknown to the general population, through a self-completion questionnaire, we investigated the behaviours and knowledge of our at-risk population belonging to the sexually transmitted infection (STI) outpatient clinic of the Infectious Diseases Unit of the ASST Spedali Civili of Brescia, Italy, between August and October 2022. Most patients that took part in the compilation are HIV positive MSM. The other participants were HIV-seronegative patients with other STIs. Overall, 144 questionnaires were compiled. Most of the participants were Italians (130;90%) and males (139;96.5%) between 30 and 60 years (118;82%). Almost all (136;94%) reported having heard about Mpox and more than half (80;56%) received information about the transmission. Twenty-four respondents (16%) received information from health professionals and 14 (10%) believed that the information received was complete. Although 41% of respondents thought they were at risk of getting the infection and 62% were afraid to get it, the majority (56%) did not increase the precautions taken. When asked if they would accept a vaccine to prevent the disease, more than a third (32%) of respondents expressed hesitation or complete refusal to be vaccinated. Based on our results, what emerges is that there is still a lack of knowledge and awareness about Mpox. To address this issue, targeted health promotion and education strategies that provide the necessary resources to reduce risk behaviours and enhance connections with healthcare professionals are needed.
