Chronic HBV infection in pregnant immigrants: a multicenter study of the Italian Society of Infectious and Tropical Diseases
The aims of the study were to estimate the clinical impact of HBV infection in pregnant immigrants and their family members and to identify a useful approach to managing the healthcare of HBsAg-positive immigrants. Included in this study were 143 HBsAg-positive pregnant immigrants of the 1,970 from countries with intermediate/high HBV endemicity who delivered in 8 Italian hospitals in 2012-2013. In addition, 172 family members of 96 HBsAg-positive pregnant immigrants were tested for serum HBsAg. The median age of the 143 HBsAg-positive pregnant immigrants was 31.0±12.1 years and the length of stay in Italy 5.0±4.1 years; 56.5% were unaware of their HBsAg positivity. HBV DNA was detected in 74.5% of the pregnant immigrants, i.e., 94.3% from Eastern Europe, 72.2% from East Asia and 58.1% from Sub-Saharan Africa. HBV DNA â„2000 IU/mL was detected in 47.8% of pregnant immigrants, associated with ALT â„1.5 times the upper normal value in 15% of cases. Anti-HDV was detected in 10% of cases. HBsAg was detected in 31.3% of the 172 family members. All HBsAg-positive immigrants received counseling on HBV infection and its prevention, and underwent a complete clinical evaluation. The findings validate the approach used for the healthcare management of the HBsAg-positive immigrant population
An accidental diagnosis of optic nerve meningioma in a patient affected by thyroid eye disease
A 42-year-old woman presented to our hospital owing to a history of right-sided proptosis of 4 months duration, reporting no previous trauma, fever, or recent sinusitis. Her medical record included a diagnosis of Gravesâ disease. The best corrected visual acuity (BCVA) was 20/20 and a 30.2 visual field test was normal. A 3-Tesla magnetic resonance imaging (MRI) revealed an orbital apex meningioma approaching the walls of the sulcus chiasmaticus. A subsequent 60.4 perimetry test showed bilateral nasal visual field defects, thus confirming the involvement of the optic nerve. The reported case focuses on the differential diagnosis with Thyroid Eye Disease (TED) and the subsequent follow-up
Sex difference in the interaction of alcohol intake, hepatitis B virus, and hepatitis C virus on the risk of cirrhosis
Background
The joint effect of the interaction of alcohol intake, hepatitis B virus (HBV) and hepatitis C
virus (HCV) on the risk of cirrhosis is still unexplored because a large sample size is required
for this investigation.
Objective
Evaluation of interaction of HBV, HCV and alcohol abuse on the risk of cirrhosis.
Design
We analysed 12,262 consecutive patients with chronic liver disease of various aetiologies referring to 95 Italian liver units in 2001 or 2014. To evaluate the interaction between alcohol abuse,
HBV infection, and HCV infection, patients unexposed to either factors were used as reference
category. Adjustment for BMI and age was done by multiple logistic regression analysis.
Results
Females were older than males (p<0.01) and less frequently showed HBV and alcoholic
aetiology (p<0.01). In both sexes, an overtime increasing age and an increasing proportion
of subjects with liver cirrhosis was observed, reflecting a better survival (0.01).An additive interaction is observed in females: the O.R. generated by the simultaneous
presence of HBV, HCV, and alcohol (5.09; 95% C.I. 1.06â24.56) exceeds the sum (4.14) of
the O.R. generated by a single exposure (O.R. = 0.72 for HBsAg positivity, OR = 1.34 for antiHCV positivity, and O.R. = 2.08 for alcohol intake). No interaction is observed in male sex.
Conclusions
The observed gender difference suggests that the simultaneous presence of HBV/HCV
coinfection and risky alcohol intake enhances the mechanism of liver damage to a greater
extent in females than in males
An anecdotal case report of chronic lymphatic leukemia with del(11q) treated with ibrutinib: Artificial nourishment and physical activity program
Chronic lymphatic leukemia (CLL) is the most frequent type of leukemia in western countries and when association with del(11q) is correlated with a worse prognosis. We reported the clinical case of an 80âyearâold patient with CLL related to del(11q) and a BMI of 16.4 kg/m2, who presented a voluminous mass in abdominal cavity (23 Ă 14 Ă 4cm) which occupied the whole of the mesentery and the retroperitoneal space, treated with ibrutinib, adequate nutrition, and a program of physical activity. He showed a great improvement under ibrutinib therapy and took to artificial nourishment and adequate muscle rehabilitation until he recovered his autonomy. In August 2018, a 5âdaysâaâweek training program was started: Physical activity for at least 20 minutes consisting of a fast walk in the open air three times a week and a moderate physical activity in the remaining two days of at least 20 consecutive minutes (cycling at a regular pace, carrying light weights). The exercise program included also aerobic, upper and lower limb resistance training, chore stability and stretches. The physical condition further improved and remained excellent throughout the followâup period. In December 2018, his clinical condition was quite normal; a CT showed a great decrease of all lymphoadenomegaly, and FISH test did not show del(11q). He continued to cultivate his land, while still being treated with ibrutinib. The combination of the right therapy, adequate nutrition, and muscle rehabilitation is the best solution to improve the clinical condition of old cachectic CLL del(11q) patient
The future of starch bioengineering:GM microorganisms or GM plants?
Plant starches regularly require extensive modification to permit subsequent applications. Such processing is usually done by the use of chemical and/or physical treatments. The use of recombinant enzymes produced by large-scale fermentation of GM microorganisms is increasingly used in starch processing and modification, sometimes as an alternative to chemical or physical treatments. However, as a means to impart the modifications as early as possible in the starch production chain, similar recombinant enzymes may also be expressed in planta in the developing starch storage organ such as in roots, tubers and cereal grains to provide a GM crop as an alternative to the use of enzymes from GM microorganisms. We here discuss these techniques in relation to important structural features and modifications of starches such as: starch phosphorylation, starch hydrolysis, chain transfer/branching and novel concepts of hybrid starch-based polysaccharides. In planta starch bioengineering is generally challenged by yield penalties and inefficient production of the desired product. However, in some situations, GM crops for starch bioengineering without deleterious effects have been achieved
Rituximab-Based Treatment, HCV Replication, and Hepatic Flares
Rituximab, a chimeric mouse-human monoclonal antibody directed to the CD20 antigen expressed on pre-B lymphocytes and mature lymphocytes, causes a profound B-cell depletion. Due to its peculiar characteristics, this drug has been used to treat oncohaematological diseases, B cell-related autoimmune diseases, rheumatoid arthritis, and, more recently, HCV-associated mixed cryoglobulinaemic vasculitis. Rituximab-based treatment, however, may induce an increased replication of several viruses such as hepatitis B virus, cytomegalovirus, varicella-zoster virus, echovirus, and parvovirus B19. Recent data suggest that rituximab-based chemotherapy induces an increase in HCV expression in hepatic cells, which may become a target for a cell-mediated immune reaction after the withdrawal of treatment and the restoration of the immune control. Only a few small studies have investigated the occurrence of HCV reactivation and an associated hepatic flare in patients with oncohaematological diseases receiving R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone). These studies suggest that the hepatic flares are frequently asymptomatic, but life-threatening liver failure occurs in nearly 10% of cases
Eradication of HCV Infection with the Direct-Acting Antiviral Therapy in Renal Allograft Recipients
New insights on the diagnosis and management of malignant tumors of the ocular surface
Tumors of the ocular surface encompass a wide spectrum of conditions involving the conjunctiva and cornea, ranging from benign lesions to life-threatening malignancies. These tumors are rare; however, they are commonly seen in the ophthalmological clinical practice as a group.
The diagnosis of ocular surface tumors is mostly based on clinical evaluation of the conjunctiva and cornea and subsequent histologic confirmation.
Recently, non-invasive diagnostic approaches including anterior segment high-resolution OCT (HROCT), showed promising results for their use as adjuvant for histology in case of suspicious lesions.
The present review focused on the main malignant ocular surface tumors, including ocular surface squamous neoplasia (OSSN), melanocytic epithelial tumors, and conjunctival lymphoma, with the aim of discussing the epidemiological, clinical, and histopathological features, as well as to provide insights into classification and staging. In addition, the latest advances in the treatment of ocular surface tumors were reviewed, including the use of topical chemotherapy, which is gaining increasing acceptance over surgical tumor removal as it prevents surgery-related side effects and tumor recurrences
The Impact of Direct Oral Anticoagulant Prophylaxis for Thromboembolism in Thrombophilic Patients Undergoing Abdominoplastic Surgery
Congenital or acquired thrombophilia is observed in 10-15% of the general population; therefore, careful screening is carried out in patients at higher risk of venous thrombo-embolism (VTE). High risk of VTE is a contraindication in patients undergoing abdominoplasty. We evaluated rivaroxaban, an oral Xa inhibitor, with enoxaparin, a subcutaneously low molecular weight heparin (LMWH), in 48 female patients with documented thrombophilia, undergoing thrombo-prophylaxis after abdominoplasty. Patients were stratified into two groups according to thrombo-prophylaxis procedure: enoxaparin Group (n = 28) and rivaroxaban Group (n = 20). Hematologic outcomes were evaluated including VTE and hematoma. No episodes of VTE occurred in both groups; two patients during their course of enoxaparin presented severe hematoma for drainage and hemostasis revision. This study suggests that abdominoplasty, in patients with thrombophilia, in combination with thrombo-prophylaxis can be performed safely. Rivaroxaban was as effective as LMWH for preventing VTE, with only a moderate risk of clinically relevant bleeding. More research is needed to determine the optimal timing and duration of prophylaxis in patients undergoing plastic surgery
Gender differences in chronic liver diseases in two cohorts of 2001 and 2014 in Italy
Background: Gender differences in chronic liver disease (CLD) have been partially investigated. To extend the present knowledge, we evaluated 12,263 patients with CLD enrolled in two national surveys (9997 in 2001 and 2557 in 2014). Methods: The two surveys prospectively recruited patients aged ù„Ă 18 referring to Italian liver units throughout the country using a similar clinical approach and analytical methods. Results: The overall male to female ratio (M/F) was 1.4 (7138/5124). Compared with females, males were significantly more likely to be younger (52.9 vs. 58.7 yrs.), with HBV infection alone (13.2% vs. 9.2%) and with alcoholic liver disease alone (11.4% vs. 6.9%), but less likely to show HCV infection alone (48.0% vs. 67.9%). A male preponderance was observed in HBV-related cases (1.99) and in alcoholic-related cases (2.3), a preponderance observed both in the 2001 and in 2014 cases. In HCV-related cases, however, females predominated in 2001 (M/F 0.9) and males in 2014 (M/F 1.5).The rate of cirrhosis in alcohol-related etiology was close to 36% in both genders, a finding much higher than that observed for both sexes in HBV and HCV etiologies.Both males and females enrolled in 2014 were older (pĂ <Ă 0.001) and with a higher rate of cirrhosis and/or HCC (pĂ <Ă 0.001) than those investigated in 2001. There was a remarkable increase over time in the proportion of male abstainers (36.7% in 2001 and 64.3% in 2014). Conclusion: This study highlights important inter- and intra-gender differences in the characteristics and etiological factors of patients with CLD in Italy
