Portal Hypertension Related to Schistosomiasis Treated with a Transjugular Intrahepatic Portosystemic Shunt

Hepatosplenic schistosomiasis represents the most common form of chronic intestinal schistosomiasis. Liver periportal fibrosis, leading to portal hypertension, is the major cause of disease morbidity and mortality, due to massive bleeding of esophageal or gastric varices.

vaccination campaign strategies in recently arrived migrants experience of an italian reception centre

Introduction: Control of vaccine preventable diseases, while constituting a priority of European health policies, is challenged by migrations from countries with suboptimal levels of immunization coverage. We report here two different types of vaccination campaign strategy in one of the bigger Italian asylum seekers' centres. The vaccination service staff of the local national health institute came monthly during the first three years of observation, while in the last year, the vaccinations were offered directly upon arrival of migrants in the asylum seekers' centre. Methodology: we performed a descriptive cross-sectional study that analysed data collected from the database of the internal healthcare facility and ARVA Target tool, regarding vaccinations performed from 2013 to 2017 in the asylum seekers' centre. Results: In the four years of observation period the asylum seekers centre hosted 3941 migrants. Among them, 85% were vaccinated during their stay, for a total of 4252 vaccinations administered, covering 95% of minors and 85% of adults. During the study period, there was an important increase from an average of 10.5% of migrants vaccinated in the first three years to 66% in the last year, when vaccines were delivered directly upon arrival in the centre. Conclusions: To improve the rate of immunization in migrants, the first requirement is a strong collaboration with the local vaccine services and the second,vaccinations must be carried out when migrants arrive at the asylum seekers' centre, avoiding any delay

Malaria in an asylum seeker paediatric liver transplant recipient: diagnostic challenges for migrant population

Transplanted patients are particularly exposed to a major risk of infectious diseases due to prolonged immunosuppressive treatment. Over the last decade, the growing migration flows and the transplant tourism have led to increasing infections caused by geographically restricted organisms. Malaria is an unusual event in organ transplant recipients than can be acquired primarily or reactivation following immunosuppression, by transfusion of blood products or through the transplanted organ. We report a rare case of Plasmodium falciparum infection in a liver transplanted two years-old African boy who presented to one Italian Asylum Seeker Center on May 2019. We outlined hereby diagnostic challenges, possible aetiologies of post-transplantation malaria and finally we summarized potential drug interactions between immunosuppressive agents and antimalarials. This report aims to increase the attention to newly arrived migrants, carefully evaluating patients coming from tropical areas and taking into consideration also rare tropical infections not endemic in final destination countries

Dirofilaria repens microfilariae from a human node fine-needle aspirate: A case report

Background: Human dirofilariosis is still a little known infection even in endemic areas. Dirofilariosis is zoonotic infection usually abortive in humans; instead, we report a very rare case (the 4th in the world), the first in Italy, in which at least two infective larvae became mature adults that mated and produced active microfilariae even though they did not reach peripheral blood. Case presentation: A 30-year-old Italian woman presented with a transient oedematous swelling on the left abdominal wall with a creeping eruption followed by the occurrence of a subcutaneous nodular painless mass in the iliac region. One month later, a similar temporary swelling appeared on the contralateral inguinal region associated with intermittent joint discomfort in both knees. The patient had recently travelled abroad, therefore many possible diagnoses were to be ruled out. Routine laboratory investigations revealed eosinophilia. An ultrasound examination of the iliac swelling evidenced a well-defined cyst with a big filamentous formation in continuous movement. A fine-needle aspiration of the lesion was performed for parasitological, cytological and histological exams. The prompt microscopic examination of the aspired material showed the presence of numerous microfilariae that were initially morphologically attributed to Mansonella ozzardi. Subsequently, the revision of the Giemsa stained film and molecular analyses of the biological material, allowed to identify Dirofilaria repens as etiological agent of infection. Conclusions: We report of a case in whom microfilariae were detected in fine-needle aspirate of subcutaneous node, without evidence of microfilaraemia, and the infection failed to become fully patent. Therefore we confirm that complete development and fertilization of D. repens worms in human hosts may occur, at variance with what is commonly believed, that Dirofilaria worms cannot fully develop in human

Vitamin D deficiency and health-related quality of life in chronic hepatitis C

Vitamin D deficiency is an important health problem in the general population and in patients with chronic hepatitis C (CHC), in which the prevalence of vitamin D deficit ranges between 46% and 92%.1 In addition to its crucial role in the regulation of bone homeostasis, vitamin D has a broad range of nonskeletal effects including cardiovascular, immunomodulatory, metabolic, neuro‐muscular and brain functions.2 Recently, several studies showed that vitamin D deficiency is associated with worsening of physical and mental functions,2 thus affecting negatively quality of life in patients with chronic diseases such as chronic kidney disease3 and rheumatoid arthritis.

Occurrence of intestinal parasites among asylum seekers in Italy: a cross-sectional study

Background: In recent years Europe has experienced a dramatic increase in migration flows. Nevertheless, limited data is available about the occurrence of neglected parasitic diseases among migrant population. The purpose of the present study was to evaluate the prevalence of intestinal and urinary parasites in newly arrived asylum seekers. Methods: A total of 364 newly arrived migrants hosted at the Asylum Seekers Centre of Castelnuovo di Porto (Italy) were screened during 8 months period for intestinal and urinary parasites. Each enrolled subject was interviewed using a standardized questionnaire, with focus on socio-demographical data and risk factors of parasitic infections. Results: Stool analysis showed a prevalence of intestinal parasites of 20.6%. The travel route did not affect the prevalence of intestinal parasites (p = 0.096), while a significant negative correlation was found between the length of travel and the prevalence of parasite infection (p = 0.019). No statistically significant correlation between gastrointestinal symptoms and the presence of intestinal parasites was detected. Conclusion: The prevalence of intestinal parasitosis reported in asylum seekers does not necessarily reflect the prevalence of the parasitosis in the motherland. An anamnestic and syndromic approach may not be sufficient to highlight the problem of intestinal parasitic infestations in a screening setting

Low-grade endotoxemia, gut permeability and platelet activation in community-acquired pneumonia

OBJECTIVES: Platelet activation seems to be implicated in the cardiovascular events occurring in patients with community-acquired pneumonia (CAP) but the underlying mechanism is still unclear. Aim of the study was to assess the mechanism involved in platelet activation in CAP patients. METHODS: Two-hundred-seventy-eight consecutive patients hospitalized for CAP were recruited and followed-up until discharge. Hospitalized patients matched for sex, age and comorbidities but without acute infectious diseases were used as controls. RESULTS: At hospital admission patients disclosed enhanced plasma levels of sP-selectin, a maker of in-vivo platelet activation, serum sNOX2-dp, a marker of NADPH-oxidase activation, serum Lipopolysaccharide (LPS) and serum zonulin, a marker of gut permeability, compared to controls (p < 0.001). Baseline sP-selectin was independently associated to serum LPS, sNOX2-sp and Pneumonia Severity Index score (p < 0.001). Plasma sP-selectin, serum sNOX2-dp, LPS and zonulin coincidentally decreased at hospital discharge (p < 0.001). An in vitro study showed that LPS, at concentration similar to that found in CAP patients, induced sP-selectin release by agonist-activated platelets, a phenomenon that was counteract by treating cells with gp91ds-tat, a specific inhibitor of NOX2. CONCLUSIONS: CAP patients display enhanced platelet activation, which is related to LPS-mediated NOX2 activation. Enhanced gut permeability seems be implicated in enhancing circulating levels of LPS
