RESUMO

Penitentiaries have a higher burden of communicable diseases compared to the general population. Prisoners should be tested for hepatitis C virus (HCV) and have direct access to treatment. We analysed the HCV cascade of care in two penitentiaries in Brescia, Northern Italy. At admission, prisoners are offered a voluntary screening for HCV, while patients with known infections are tested with an HCVRNA measurement. We performed an observational retrospective study including all the subjects admitted to the penitentiaries from 1 January 2015 to 31 October 2021. We conducted a descriptive analysis. During the study period, 5378 admissions were registered, and 2932 (54.5%) screenings were performed. Hepatitis C virus antibody positivity was found in 269 tests (9.2%). Hepatitis C virus RNA was detectable in 169 people. During the study period, 77 treatments with direct-acting antivirals (DAAs) were administered. Follow-up was available in 45 patients, and sustained virological response (SVR) was documented in 44 of them. Retention in care occurred in less than half of the prisoners after release. Our data demonstrate poor screening adherence that could benefit from educational programs. Treatment rates could be improved with test-and-treat programs. More efforts are needed to eliminate HCV as a public threat by 2030. Dedicated local networks, including infectious diseases (ID) departments, substance abuse services and prisons, could mitigate these issues.

RESUMO

The natural history of occult hepatitis B virus infection (OBI) and the mechanism involved in HBV reactivation are only partially understood. As regards people living with HIV (PLWH), HBV reactivation is estimated to occur with an incidence ratio of 0.019 cases per 100 person-year. Here we report the case of OBI reactivation in a HIV/HCV co-infected patient followed for 25 years at our Infectious Diseases Unit, but, unfortunately, lost to follow-up about 19 months after Direct-acting antivirals (DAAs) treatment. At re-engagement, blood tests showed high replication of plasmatic HIV-RNA along with severe immunosuppression and normal levels of liver enzymes. However, 3 months after ART reintroduction, an immune reconstitution inflammatory syndrome (IRIS) was diagnosed with high detectable HBV-DNA load and transaminase elevation. Our case report shows how the balance between the virus and the host immune system is quite a dynamic process that might significantly impact the course of the disease. The aim of this case report is to bring to the attention of physicians that, although OBI reactivation is a rather rare occurrence, even amongst PLWH, its potential consequences compel to a high alertness on the matter. Therefore, especially in patients with an impaired immune system and on a tenofovir or lamivudine-sparing regimen, HBV serological and virological markers should always be strictly monitored, even in the absence of a hepatitis flare.

RESUMO

Bacillus Calmette-Guerin (BCG) immunotherapy (i.e., intravesical instillation of live attenuated strain of Mycobacterium bovis) is a standard of care for non-muscle-invasive bladder cancer (NMIBC). The risk of infective adverse events is generally low as studies have reported an incidence of systemic BCG infections between 3% and 7%. In the majority of cases, BCG infections are disseminated (34.4%), genitourinary (23.4%), osteomuscular (19.9%), or vascular (6.7%). Regarding vascular involvement, mycotic aortic aneurysm, aorto-enteric fistula and vascular bypass graft infections have been described. A 73-year-old man with a prosthetic femoral-popliteal bypass was treated with BCG immunotherapy for a relapsed NMIBC. Two months later, the patient developed fever and hyporexia. PET-CT and CT scans of the abdomen showed an abscess surrounding the superficial femoral artery, while blood cultures yielded M. bovis BCG, and antitubercular therapy (with RMP + EMB + INH) was started. The prosthetic graft was removed and its cultures tested positive for M. bovis as well. A total of 14 cases of vascular prosthesis infections caused by M. bovis BCG following BCG instillation are so far reported. All the cases occurred in adult symptomatic men. Abdominal aorta was involved in the majority of cases. CT scan played a pivotal role in the diagnostic process. Mycobacterium bovis BCG was isolated from several different sources. Treatment required surgery and medical therapy, the latter showing wide variability. Previous BCG immunotherapy must be considered in the differential diagnosis in patients with infected vascular grafts. These infectious complications are rare and, while the infected grafts should be removed, there are no definite recommendations regarding the type of regimen and duration of treatment.
