Ultrasound Evaluation of Tendinopathy in Hemophiliac Patients for the Purpose of Rehabilitation Indications.

BACKGROUND: Hemophilia is a inherited bleeding disorder that is characterized by intra-articular bleeding (hemarthrosis). The aim of the study was to evaluate the state of the satellite tendons of the target joints in the patient with hemophilic arthropathy and propose rehabilitation treatment with eccentric exercises. METHODS: The tendons of the joints mainly affected by hemophilic arthropathy were evaluated by ultrasound. The ultrasound evaluation is associated with the use of evaluation clinical scales, such as the Hemophilia Joint Health Score (HJHS), the Functional Independence Score in Hemophilia (FISH), the Hemophilia Activity List (HAL), the DASH, the VISA-A, the VISA-P, and the VAS scale. RESULTS: In 20 patients with hemophilic arthropathy, the thickness of the tendons that were examined was normal. In six subjects with severe joint damage, echostructural alterations were present, and signs of hyperemia and neo-vascularization were detected on color Doppler, as well as the presence of intratendinous calcifications. CONCLUSIONS: The tendons of the target joints in patients with hemophilic arthropathy are compromised by the indirect biomechanical damage caused by the joint disease, and rehabilitation treatment with eccentric exercises can be considered safe and effective in improving the tenso-elastic properties of the tendons.

IDEAL study: A real-world assessment of pattern of use and clinical outcomes with recombinant coagulation factor IX albumin fusion protein (rIX-FP) in patients with haemophilia B in Italy.

INTRODUCTION: Factor IX replacement therapy is used for treatment and prophylaxis of bleeding in haemophilia B. rIX-FP is an extended half-life albumin-fusion protein, which, in clinical studies, has demonstrated prolonged dosing intervals up to 21 days for routine prophylaxis, providing therapeutic benefit. AIMS: To describe dosing frequency and consumption (primary endpoint), efficacy and safety of rIX-FP treatment during routine clinical practice in Italy. METHODS: Patients with moderate/severe haemophilia B on prophylaxis with rIX-FP for ≥6 months, were enrolled in this observational study from October 2017 to February 2019 and followed-up for 2 years. Descriptive analysis included prospective and retrospective data (12 months prior to switching to rIX-FP). RESULTS: Data were collected from 59 male patients (median age 30.1 years) enrolled by 23 Italian centres. Of them, 50 were on prophylaxis during the entire observation period and completed the study. The infusion frequency changed from 2-3 times/week in 86.0% of patients with previous treatment, to less than once a week in 84.0% of patients treated with rIX-FP at the 2nd-year follow-up. The annual number of infusions decreased by about 70%, whereas the mean FIX activity trough level increased from 3.8% to 14.4% (mean > 10% in all the infusion regimens). Median Annualised Bleeding Rate of .0 was achieved across all prophylaxis regimens. Subjects with zero bleedings increased from 66.0% to 78.0% with rIX-FP. CONCLUSION: Treatment with rIX-FP reduced infusion frequency, while providing higher FIX trough levels with substantial benefit in terms of annualised bleeding rate and a good safety profile.

The effect of carriers' reproductive choices and pregnancy history on sporadic severe haemophilia: A 20-year retrospective study through a regional registry.

INTRODUCTION: Haemophilias are X-linked inherited bleeding disorders, due to de novo F8/F9 gene variants in 30-50% of cases. The identification of causative variant in index cases (IC) is crucial for genetic counselling in related women. Over the last 20 years the Emilia-Romagna Regional Haemophilia Registry documented high proportions of sporadic severe haemophilia. AIM: To clarify if carriers' reproductive choices influence the sporadic/familial ratio of severe haemophilia. METHODS: Genetic counselling and genotyping in 221 relatives of severe IC were retrospectively reviewed, retrieving reproductive choices and pregnancy history of childbearing-age carriers from familial and sporadic pedigrees and according to the IC degree of relationship (mothers, daughters, II/other). RESULTS: Carriers' identification rates were lower in sporadic women and in other-degree relatives. Among childbearing age women (n = 140), carriers were 37/48 (77%) and 57/92 (62%) of familial and sporadic relatives, respectively. Forty-five/57 sporadic carriers experienced 67 pregnancies, while 21/37 familial carriers had 39 pregnancies (four voluntary terminations), with a significantly higher number of affected sons in the former (40/67 vs. 12/35, P = .025). Prenatal diagnosis was chosen by 40% and 47% of sporadic and familial aware carriers, respectively. Sporadic mothers often avoided further pregnancies (17/38, 45%) after a firstborn affected child, while familial mothers tended to face pregnancies without prenatal approaches (6/10, 60%). CONCLUSION: In this cohort sporadic offspring account for more than 70% of severe haemophilia cases. This increasing proportion is likely to reflect the influence in reproductive choices of awareness of carriers' status, particularly in sporadic mothers, and of prenatal diagnosis options.

Contrast-enhanced ultrasound in the differential diagnosis of exocrine versus neuroendocrine pancreatic tumors.

OBJECTIVES: Contrast-enhanced ultrasound (CEUS) has been developed to better characterize the microvasculature of solid masses in several organs, including the pancreas. In this study, we assessed CEUS accuracy in differentiating exocrine from endocrine pancreatic tumors. METHODS: A total of 127 patients with single, undetermined pancreatic masses were prospectively examined with transabdominal ultrasound and CEUS, before surgical resection or percutaneous biopsy. RESULTS: Exocrine and endocrine pancreatic tumors showed different intralesional vascularization patterns: 98.9% (90/91) of exocrine tumors were hypoenhancing, whereas 95.8 % (23/24) of endocrine tumors had a hypervascular supply. A hypoenhancing pattern, indicative of ductal adenocarcinoma, had a significant (P < 0.001) diagnostic accuracy of 91.3% with a sensitivity of 96.8%, a specificity of 85.3%, a positive predictive value and a negative predictive value of 94.7% and 90.6%, respectively. The hyperenhancing pattern, indicative of endocrine tumors, had a significant (P = 0.031) diagnostic accuracy of 73.8% with a sensitivity of 83.3%, a specificity of 60.0%, a positive predictive value and negative predictive value of 83.3% and 60.0%, respectively. CONCLUSIONS: Contrast-enhanced ultrasound has a valuable diagnostic accuracy in differentiating exocrine from endocrine pancreatic tumors, which is a fundamental step to address appropriate histological evaluation, therapeutic approach, and follow-up.

Endocrine tumors of the ileum: factors correlated with survival.

AIM: To evaluate the most important factors correlated with survival in patients with endocrine tumors of the ileum, both at the time of diagnosis and during the follow-up period. METHODS: Fifty-nine patients with ileal endocrine tumors diagnosed in our institution between 1990 and 2004 were studied. RESULTS: The study included 36 men (61%) and 23 women (39%). The median age of the patients at the time of diagnosis was 61.4 (range 18-83) years. The median follow-up period was 71.9 (range 5-287) months. Forty patients (67.8%) were still alive at the end of the study; the median survival time was 172 months, and the 5-year survival rate was 78.9%. By univariate analysis, the survival rate was significantly related to female sex (p = 0.024) and flushing alone (p = 0.028) and associated with diarrhea at diagnosis (p = 0.015), weight loss at diagnosis (p = 0.038), Ki-67 level (p = 0.025), stage of disease at diagnosis (p = 0.012), presence of liver metastases at follow-up (p = 0.005), presence of diffuse metastases at diagnosis (p = 0.005) and at follow-up (p = 0.007), and type of surgical approach (overall: p = 0.018; not operated vs. radical surgery: p = 0.008; not operated vs. palliative surgery: p = 0.045). Using multivariate analysis, only female gender (p = 0.012) and the presence of liver metastases at follow-up (p = 0.004) were significantly related to survival. CONCLUSION: In the present study, female gender and the appearance of liver metastases at follow-up seem to be the main conditions which determine the poor prognosis of patients with ileal endocrine tumors.

Adult coeliac disease diagnosed by endoscopic biopsies in the duodenal bulb.

Multiple endoscopic biopsies in the descending duodenum are usually recognized as the standardized method for the evaluation of mucosal changes in coeliac disease. Generally, the duodenal bulb is not considered a useful site for biopsies, due to some difficulties in histological evaluation. A case in which the diagnosis of coeliac disease was possible only with the aid of biopsies in the duodenal bulb is reported; noteworthy, this unusual site for biopsies was strongly suggested by the presence of a mosaic-like endoscopic appearance. Only few cases (mainly in childhood) have been reported in which diagnosis was made with the aid of biopsies in the duodenal bulb. This occurrence suggests that performing biopsies only in the descending duodenum may not be sufficient in some patients, and raises the question of whether obtaining specimens both from the first and the second part of the duodenum might be a more correct and complete approach to this problem.

Treatment of Zollinger-Ellison syndrome.

In this article, we have reviewed the main therapeutic measures for the treatment of Zollinger-Ellison syndrome (ZES). Review of the literature was based on computer searches (Pub-Med, Index Medicus) and personal experiences. We have evaluated all the measures now available for treating patients with sporadic gastrinomas or gastrinomas associated with Multiple Endocrine Neoplasia Type 1, (MEN 1) including medical therapy such as antisecretory drugs and somatostatin analogs (SST), chemotherapy and chemoembolization, and surgical procedures. In ZES patients, the best therapeutic procedure is surgery which, if radical, can be curative. Medical treatment can be the best palliative therapy and should be used, when possible, in association with surgery, in a multimodal therapeutic approach.
