Malaria Clusters among Illegal Chinese Immigrants to Europe through Africa

Between November 2002 and March 2003, 17 cases of malaria (1 fatal) were observed in illegal Chinese immigrants who traveled to Italy through Africa. A further cluster of 12 was reported in August, 2002. Several immigrants traveled by air, making the risk of introducing sudden acute respiratory syndrome a possibility should such illegal immigrations continue

Mefloquine versus Quinine plus Sulphalene-Pyrimethamine (Metakelfin) for Treatment of Uncomplicated Imported Falciparum Malaria Acquired in Africa

We conducted a multicenter, randomized, open-label trial to compare mefloquine with a 3-day quinine plus sulphalene-pyrimethamine (SP) regimen for the treatment of imported uncomplicated malaria acquired in Africa. The end points of the study were efficacy, tolerability, and length of hospital stay. From July 1999 to February 2003, 187 patients were enrolled in five centers in Italy, of whom 93 were randomized to receive mefloquine (the M group) and 94 were randomized to receive quinine plus SP (the QSP group). Immigrants and visiting relatives and friends represented 90% of the cases and were mainly from western African countries. A slightly increased proportion of cases in the QSP group had abnormal alanine aminotransferase levels at the baseline. The early cure rate was similar in the two groups: 98.9% (confidence interval [CI] = 97 to 100%) in the M group and 96.8% (CI = 93 to 100%) in the QSP group. The extended follow-up was completed by 135 subjects (72.2%), and no case of recrudescence was detected. There were no differences in the parasite clearance time, but patients in the M group had shorter mean fever clearance time (35.9 h versus 44.4 h for the QSP group; P = 0.05) and a shorter mean hospital stay (3.9 days versus 4.6 days for the QSP group; P = 0.007). The overall proportions of reported side effects were similar in the two groups, but patients in the M group had a significantly higher rate of central nervous system disturbances (29.0% versus 9.6% for the QSP group; P < 0.001)

Real-Time PCR Assay for Clinical Management of Human Immunodeficiency Virus-Infected Patients with Visceral Leishmaniasis

To evaluate the usefulness of a real-time PCR for Leishmania DNA in the diagnosis and follow-up of patients with human immunodeficiency virus type 1 (HIV-1) and Leishmania coinfection, Leishmania DNA levels were measured in whole peripheral blood from 25 HIV-infected patients with clinical features suggestive of visceral leishmaniasis. Leishmania DNA was detected in 10 of 25 patients with microscopically confirmed visceral leishmaniasis and in none of those without this disease. Following treatment with liposomal amphotericin B, a clinical response was observed in 9 of 10 patients, in association with significantly decreased parasite loads. Seven patients relapsed clinically a median of 110 days after the end of treatment, in association with substantial increases in Leishmania DNA levels. Leishmania DNA levels correlated with the clinical course of visceral leishmaniasis, and their measurement at diagnosis and during and after treatment seems to be useful in the clinical management of HIV-infected patients with this disease

Delay in schistosomiasis diagnosis and treatment: a multicenter cohortstudy in Italy

14noBACKGROUND: Barriers to access to care, different diagnostic strategies, and low awareness remain challenging issues in the fight against schistosomiasis.Our study aims to examine management of schistosomiasis in migrants attending large tertiary hospitals in Italy, in order to call for a comprehensive approach. METHODS: A retrospective review of schistosomiasis cases was carried out between January 1, 2016 and December 31, 2017 in five large Infectious Disease Centers in Italy. We included all patients diagnosed with schistosomiasis. We differentiated among i) asymptomatic patients diagnosed by serology either as healthy 'migrant evaluation' or as 'late evaluation' in patients followed because of a different infection and ii) patients tested because of a suggestive clinical presentation. Patients characteristics and clinical data were recorded. RESULTS: 149 patients were included, 137 (91.9%) were male, the median age was 26 years and 70% of them came from Sub-Saharan Africa.Thirty-eight asymptomatic patients (25.5%) were diagnosed by serology [15, (10.1%) among 'migrant evaluation' and 23 (15.4%) among 'late evaluation' group] and 111 (74.5%) presented with signs/symptoms.The median diagnostic delay from arrival in Italy was 31 months: 110 for asymptomatic group and 16 months for symptomatic patients. Among the 111 symptomatic patients, 41 individuals were already followed in our Clinics and they never underwent screening before appearance of evident disease. Among patients with positive serology who were tested by microscopy, 32/86 (37.2%) had confirmed diagnosis. Forty-five (37.8%) patients presented radiologic abnormalities. Praziquantel was the treatment of choice (70.1% for 3 days and 29.9% in a single-day dose) and 77 (51.7%) were lost to follow-up. CONCLUSION: In our centers, a high proportion of patients were tested late after arrival and most of them presented with clinical apparent disease. Well-defined strategies and implementation of recent guidelines are needed to improve early diagnosis and to overcome heterogeneity of practice.nonenoneComelli, Agnese; Riccardi, Niccolò; Canetti, Diana; Spinicci, Michele; Cenderello, Giovanni; Magro, Paola; Nicolini, Laura Ambra; Marchese, Valentina; Zammarchi, Lorenzo; Castelli, Francesco; Bartoloni, Alessandro; Di Biagio, Antonio; Caligaris, Silvio; Gaiera, GiovanniComelli, Agnese; Riccardi, Niccolò; Canetti, Diana; Spinicci, Michele; Cenderello, Giovanni; Magro, Paola; Nicolini, Laura Ambra; Marchese, Valentina; Zammarchi, Lorenzo; Castelli, Francesco; Bartoloni, Alessandro; Di Biagio, Antonio; Caligaris, Silvio; Gaiera, Giovann

Role of PCR in diagnosis and prognosis of visceral leishmaniasis in patients coinfected with human immunodeficiency virus type 1

A group of 76 consecutive human immunodeficiency virus (HIV)-positive patients with fever of unknown origin (n = 52) or fever associated with pulmonary diseases was evaluated in order to assess the usefulness of PCR with peripheral blood in the diagnosis and follow-up of visceral leishmaniasis. We identified 10 cases of visceral leishmaniasis among the 52 patients with fever of unknown origin. At the time of diagnosis, all were parasitemic by PCR with peripheral blood. During follow-up, a progressive decline in parasitemia was observed under therapy, and all patients became PCR negative after a median of 5 weeks (range, 6 to 21 weeks). However, in eight of nine patients monitored for a median period of 88 weeks (range, 33 to 110 weeks), visceral leishmaniasis relapsed, with positive results by PCR with peripheral blood reappearing 1 to 2 weeks before the clinical onset of disease. Eight Leishmania infantum and two Leishmania donovani infections were identified by PCR-restriction fragment length polymorphism analysis. PCR with peripheral blood is a reliable method for diagnosis of visceral leishmaniasis in HIV-infected patients. During follow-up, it substantially reduces the need for traditional invasive tests to assess parasitological response, while a positive PCR result is predictive of clinical relapse

Respiratory syndrome and respiratory tract infections in foreign-born and national travelers hospitalized with fever in Italy

We measured frequency and epidemiologic, clinical, and hematochemical variables associated with respiratory tract infections (RTIs) in foreign-born and national patients hospitalized with fever with a history of international travel, and compared the final diagnosis of RTI with the presence of a respiratory syndrome (RS) at presentation

Schistosomiasis, strongyloidiasis and Chagas disease: the leading imported Neglected Tropical Diseases in Italy

In recent years, an increasing number of individuals affected by Neglected Tropical Diseases (NTDs) has been observed in Italy, due to migration, international travels, and climate changes. Reliable data on the current NTD epidemiology in Italy and the health system preparedness on this issue are not available
