Diffuse Cutaneous Metastases as the Only Sign of Extranodal Tumor Spread in a Patient with Adenocarcinoma of the Colon

Cutaneous metastases from large bowel cancer are uncommon and are usually associated with organ involvement. Localization of lesions to the skin is mainly attributed to vascular and anatomical relationship, since most of them are seen in the abdominal wall or in a surgical scar. We report a 73-year-old woman in whom metastatic nodules from a poorly differentiated adenocarcinoma of the right colon developed throughout the skin (buttock, trunk, chest wall, arms, and neck) and remained the only sign of extranodal tumor spread until patient's death, seven months later. This unusual behaviour suggests that localization of neoplastic cells to the skin may be a site-specific process, determined by adhesion molecules and/or by growth factors found at that site

Vertebral anti-fracture efficacy of strontium ranelate according to pre-treatment bone turnover

Osteoporotic post-menopausal women patients in two randomised trials comparing the anti-fracture efficacy of strontium ranelate with placebo were separated into tertiles according to their baseline levels of biochemical markers of bone formation and resorption. The vertebral anti-fracture efficacy of strontium ranelate was shown to be independent of baseline bone turnover levels. INTRODUCTION: Bone turnover (BTO) levels vary among women at risk of osteoporotic fracture. Strontium ranelate is an anti-osteoporotic treatment increasing bone formation and reducing bone resorption. It was hypothesised that its anti-fracture efficacy would be independent of baseline BTO levels. METHODS: Post-menopausal women with osteoporosis from two pooled studies were stratified in tertiles according to baseline levels of two BTO markers: bone-specific alkaline phosphatase (b-ALP, n = 4995) and serum C-telopeptide cross-links (sCTX, n = 4891). Vertebral fracture risk was assessed over 3 years with strontium ranelate 2 g/day or placebo. RESULTS: In the placebo group, relative risk of vertebral fractures increased with BTO tertiles by 32% and 24% for patients in the highest tertile for b-ALP and CTX, respectively, compared to those in the lowest tertile. In the strontium ranelate group, incidences of vertebral fracture did not differ significantly across BTO tertiles. Significant reductions in vertebral fractures with strontium ranelate were seen in all tertiles of both markers, with relative risk reductions of 31% to 47% relative to placebo. Risk reduction did not differ among tertiles (b-ALP: p = 0.513; sCTX: p = 0.290). CONCLUSION: The vertebral anti-fracture efficacy of strontium ranelate was independent of baseline BTO levels. Strontium ranelate offers clinical benefits to women across a wide range of metabolic states

Therapeutic drug monitoring is more cost-effective than a clinically-based approach in the management of loss of response to infliximab in inflammatory bowel disease: an observational multi-centre study.

BACKGROUND: Empirical dose intensification and therapeutic drug monitoring (TDM) of infliximab (IFX) trough levels (ITL) and antibody (ATI) assays are recognised approaches for managing the loss of response (LoR) in inflammatory bowel disease (IBD) patients. AIM: To compare these two interventions in a clinical setting, in terms of effectiveness and cost savings. METHODS: Consecutive IBD patients, experiencing LoR, were clinically managed according to a TDM algorithm. A historical group of empirically treated patients, for whom sera for ITL and ATI assays were collected, served as the control group. Clinical outcomes 12 weeks after the therapeutic interventions were compared between the two groups. A cost-minimization analysis was performed to compare the economic impact of these two approaches. RESULTS: Ninety-six patients were enrolled prospectively and compared with 52 controls. The two cohorts were similar in characteristics and the distribution of TDM results. In the prospective cohort, however, we observed less IFX dose escalations compared with controls (45% versus 71%, p=0.003). Also, more patients were switched to a different anti-TNF\uf061 in the prospective cohort than in the control one (25% versus 4%, p=0.001). The percentages of patients achieving a clinical response at 12 weeks were 52% and 54% for the prospective and control groups, respectively. By cost analysis, we estimated a savings of 15% if the TDM algorithm was applied. CONCLUSIONS: In our population, applying a TDM algorithm for LoR to IFX resulted in less dose escalations, without loss of efficacy, compared with empirical adjustment. In addition, the TDM approach was cost-effective

Consensus statement of the Italian society of pediatric allergy and immunology for the pragmatic management of children and adolescents with allergic or immunological diseases during the COVID-19 pandemic

International audienceAbstract The COVID-19 pandemic has surprised the entire population. The world has had to face an unprecedented pandemic. Only, Spanish flu had similar disastrous consequences. As a result, drastic measures (lockdown) have been adopted worldwide. Healthcare service has been overwhelmed by the extraordinary influx of patients, often requiring high intensity of care. Mortality has been associated with severe comorbidities, including chronic diseases. Patients with frailty were, therefore, the victim of the SARS-COV-2 infection. Allergy and asthma are the most prevalent chronic disorders in children and adolescents, so they need careful attention and, if necessary, an adaptation of their regular treatment plans. Fortunately, at present, young people are less suffering from COVID-19, both as incidence and severity. However, any age, including infancy, could be affected by the pandemic. Based on this background, the Italian Society of Pediatric Allergy and Immunology has felt it necessary to provide a Consensus Statement. This expert panel consensus document offers a rationale to help guide decision-making in the management of children and adolescents with allergic or immunologic diseases
