RESUMO
OBJECTIVES: We describe the preliminary results of bulevirtide compassionate use in patients with hepatitis B and delta virus (HBV/HDV)-related cirrhosis and clinically significant portal hypertension, including those living with HIV. METHODS: We conducted a prospective observational study of consecutive patients. Clinical evaluation, liver function tests, bile acid levels, HDV-RNA, HBV-DNA, hepatitis B surface antigen, and liver and spleen stiffness were assessed at baseline and after treatment months 1, 2, 3, 4, 6, 9, and 12. HIV-RNA and CD4+/CD8+ count were assessed in people living with HIV. The first drug injection was administered under nurse supervision, and counselling was provided and adherence reviewed at each visit. RESULTS: In total, 13 patients (61.5% migrants) were enrolled. The median treatment duration was 11 months. At month 6, mean alanine aminotransferase (ALT) levels fell by 64.5% and mean liver and spleen stiffness decreased by 8.6 and 0.9 kPa, respectively. The mean baseline HDV-RNA was 3.34 log IU/mL and 5.10 log IU/mL in people without and with HIV (n = 5) (p = 0.28), respectively. A similar mean decline was observed in both groups: -2.06 log IU/mL and -1.93 log IU/mL, respectively (p = 0.87). A combined response (undetectable HDV RNA or ≥ -2 log IU/mL decline vs. baseline, with ALT normalization) was achieved in 66% of subjects without and in 60% of patients with HIV. Patients with HIV showed persistently undetectable HIV-RNA and a progressive increase in CD4+/CD8+ cells during treatment. No patient discontinued bulevirtide because of adverse effects. CONCLUSIONS: Preliminary results suggest that bulevirtide is feasible and well-tolerated in populations with difficult-to-treat conditions, such as those with HIV/HBV/HDV co-infection and migrants, when special attention is given to patient education. HDV-RNA decline during treatment was similar in people living with and without HIV.

Rectal prolapse is a disorder in which the rectum protrudes from the anal canal. Solitary rectal ulcer may coexist. Both conditions have been associated with chronic constipation and excessive straining during defecation. Rectal prolapse has been rarely reported in women suffering from anorexia nervosa. Lack of rectal support because of loss of ischiorectal fat has been proposed as one of the possible mechanisms in this condition, together with chronic constipation and abuse of laxative. We report the case of an anorexic woman with a severe rectal prolapse and bleeding requiring urgent Altmeier's procedure. Surgery was complicated by dehiscence of the anastomosis and volvulus, requiring ileostomy and laciniae debridement. Pathological analysis of all the surgical samples taken from different abdominal sites highlighted changes in the visceral adipose tissue consisting in nodular aggregates of small adipocytes dispersed in a myxoid matrix surrounding blood vessels within abundant fibrosis. The morphologic features resemble those observed in primordial fetal fat and are comparable to those observed in cancer associated cachexia. The diffuse myxoid degeneration of visceral adipose tissue may play a role in the pathogenesis of rectal prolapse in patients with anorexia nervosa. Besides starvation, the mechanism sustaining myxoid degeneration of the adipose tissue is not entirely clear. Whenever possible improving nutritional and clinical conditions should be ideal before any surgical approach.

Small hepatic veins Budd-Chiari syndrome is a rare disorder characterized by hepatic venous outflow obstruction limited to the small intrahepatic veins, with normal appearance of the large hepatic veins at imaging. In this case only a liver biopsy can demonstrate the presence of a small vessels outflow block. Paroxysmal nocturnal haemoglobinuria (PNH) is one of the most severe acquired thrombophilic state and represents one of the main aetiological factors of Budd-Chiari syndrome. In patient affected by PNH with liver impairment and/or ascites, Budd-Chiari syndrome must be always taken into consideration and, if necessary, a liver biopsy performed to exclude the small hepatic veins involvement. We report a case of small hepatic veins Budd-Chiari syndrome secondary to paroxysmal nocturnal haemoglobinuria.

Hepatitis B virus (HBV) reactivation strongly affects the practice of physicians dealing with hematological malignancies. In this respect, in collaboration with the Italian Lymphoma Foundation we developed a descriptive study of the real-life approach of physicians caring for patients with these diseases. A questionnaire was designed to explore the perception of HBV reactivation-related issues. Fifty-nine Italian Lymphoma Foundation-affiliated institutions participated, and 504 questionnaires were sent out. Forty institutions (67.8%) returned 154 (30.5%) completed questionnaires. The largest majority (91.5%, 141/154) were aware of possible HBV reactivation as a consequence of immunosuppression. Most of the participants providing an answer (93.3%; 126/135) performed universal screening, and were aware of strategies for managing reactivation (96.4%, 132/137). Specialists treating lymphoma show a high level of awareness concerning the management of HBV reactivation under immunosuppression. However, uncertainties regarding the issue of HBV reactivation still emerge in this setting, and thus continuing collaborative effort between hepatologists and hematologists is necessary.

Rituximab has provided a revolutionary contribution to the treatment of B-cell non-Hodgkin's lymphomas (NHL). A high prevalence of hepatitis C virus (HCV) infection has been described in B-cell NHL patients. Cases of liver dysfunction in HCV-positive patients have been reported with Rituximab-containing regimens. In this paper we review the recent data regarding the effects of Rituximab in NHL patients with HCV infection. We also added a section devoted to improving communication between oncohaematologists and hepatologists. Furthermore, we propose a common methodological ground to study hepatic toxicity emerging during chemotherapy.
RESUMO
Hepatitis B virus (HBV) infection affects a large part of the world population. Different virological HBV categories have been identified and managing strategies for immunosuppressed patients with serological signs of current or past HBV infection has been proposed. Those strategies developed to manage patients in the haematology setting are based on strong evidence. Instead, management of such patients in the rheumatologic setting, especially those treated with biologic response modifiers, is mainly based on data derived by case reports and expert opinions. More data are needed to better manage these patients in case of signs of current or past HBV infection.
