The article focuses on the disease leishmaniasis, whose case has been reported from southern parts of Italy. In Italy, leishmaniasis is endemic in the southern regions, with Leishmania infantum accounting for most of the clinical cases. An unusual case of visceral leishmaniasis that occurred in a nonendemic area after a protracted incubation period, has been discussed in the article. The complete chronology of the treatment carried out in the illustrated case has been included in the article. This case serves as a reminder that visceral leishmaniasis must be suspected even in nonendemic areas. It also demonstrates that experience with both bone marrow examination and specific antibody tests is essential for an accurate diagnosis.

The availability of long-acting cabotegravir and rilpivirine injection combination requires some changes in service delivery of outpatient HIV clinics; it is therefore important for clinicians to know the potential number of people living with HIV (PLWH) who are interested in a long-acting antiretroviral treatment. We aimed to determine in an outpatient clinic the number of PLWH, on dolutegravir/rilpivirine, accepting a switch to an injectable long-acting antiretroviral treatment, and the reasons underlying this choice. In our single-center study, in this subset of HIV-infected patients, the main cause for refusal of a long-acting injectable regimen was the need for the administration to be done in hospital, as required in Italy, suggesting that current regulations about this aspect must be changed.

Mycoplasma hominis and Ureaplasma urealyticum are associated with chorioamnionitis, preterm delivery and pelvic inflammatory disease. The aim of this study was to evaluate the possible risk factors of co-colonization by M. hominis in patients already colonized by U. urealyticum and compare demographic parameters, vaginal pH and microbiota of women colonized by U. urealyticum or M. hominis. A total of 452 patients positive for U. urealyticum or M. hominis were analysed, 421 (93.1%) of whom were positive for U. urealyticum and 31 (6.9%) for M. hominis. Patients positive for M. hominis compared to patients positive for U. urealyticum were more frequently colonized by Gardnerella vaginalis (71% vs 18.5%; p 0.0001), less frequently by lactobacilli (16.1% vs 61.5%; p 0.0001), and more frequently had a pH value higher than 4.5 (96.8% vs 57%; p 0.0001), all conditions associated to bacterial vaginosis (BV). Logistic regression analysis showed that only G. vaginalis colonization and pH higher than 4.5 were independently related to M. hominis colonization (respectively p 0.0001 and p 0.016). Thus, in women colonized by U. urealyticum, BV is an independent risk factor for M. hominis co-colonization.

We report the case of a 9-year-old Senegalese girl with co-occurring wild-type (HBeAg-positive) chronic hepatitis B and antinuclear antibody-positive autoimmune hepatitis. Her HLA haplotype was A1, B8, DRB1*04, DQB1*02. Steriod and lamivudine therapy led to biochemical remission, and reactivation occurred when the patient stopped steroids. Persistent HBV infection due to wild-type virus (likely acquired vertically or early in life, as the mother was HBsAg positive) may have acted as a trigger for autoimmune hepatitis in this young girl.

In a retrospective study conducted in an Italian tertiary care hospital, the incidence of nosocomial candidemia was evaluated together with causative pathogens, treatment, and risk factors for death. Over a 6-year period (1992-1997), a total of 189 episodes of candidemia occurred in 189 patients (mean age 58+/-19 years), accounting for an average incidence of 1.14 episodes per 10,000 patient-days per year. The most common reasons for hospitalization were solid neoplasia (21%), trauma (17%), abdominal diseases requiring surgery (13%), and cardiovascular diseases (13%). No patient was neutropenic within 3 weeks prior to the onset of candidemia. One hundred thirty patients were hospitalized in intensive care units, 47 patients in surgical wards, and 12 patients in medical wards. Candida albicans was the most frequently isolated pathogen, accounting for 54% of fungal isolates, followed by Candida parapsilosis (23%), Candida glabrata (7%), Candida tropicalis (5%), Candida pelliculosa (4%), Candida lusitaniae (1%), Candida humicula (1%), and other non-albicans Candida spp. (5%). Seventy-six (41%) patients received adequate antifungal therapy. Seventy-one (58%) of the 123 evaluable patients with central venous catheters underwent line removal; 51 of them had catheter-related candidemia. The 30-day crude mortality rate was 45%. Older age, hospitalization in an intensive care unit, a longer duration of candidemia, retention of central lines, and inadequate antifungal therapy were significantly associated with poor outcome. In the present study, nosocomial candidemia was a frequent and relatively underestimated illness. Adequate antifungal therapy and central line removal independently reduced the high mortality of the disease.
