Updated Position of the Spanish Psoriasis Group (GPs) on the Use of Biosimilar Drugs in Moderate to Severe Psoriasis

The advent of biosimilar drugs and their use in routine clinical practice has revolutionized the management of moderate to severe psoriasis and led to changes in the positioning of the existing molecules used to control this condition. Evidence from clinical trials complemented by real-world experience has helped to clarify concepts and has significantly changed the use and positioning of biologic agents in this setting. The present document is an update on the position of the Spanish Psoriasis Working Group regarding the use of biosimilar drugs, which takes into account this new situation.

Medical and Legal Aspects of the Practice of Teledermatology in Spain

Teledermatology is now fully incorporated into our clinical practice. However, after reviewing current legislation on the ethical aspects of teledermatology (data confidentiality, quality of care, patient autonomy, and privacy) as well as insurance and professional responsibility, we observed that a specific regulatory framework is still lacking and related legal aspects are still at a preliminary stage of development. Safeguarding confidentiality and patient autonomy and ensuring secure storage and transfer of data are essential aspects of telemedicine. One of the main topics of debate has been the responsibilities of the physicians involved in the process, with the concept of designating a single responsible clinician emerging as a determining factor in the allocation of responsibility in this setting. A specific legal and regulatory framework must be put in place to ensure the safe practice of teledermatology for medical professionals and their patients.

Everolimus-based immunosuppression in patients with hepatocellular carcinoma at high risk of recurrence after liver transplantation: a case series

BACKGROUND

Liver transplantation offers the most effective treatment in patients with hepatocellular carcinoma (HCC). However, transplant patients outside the Milan criteria have a high risk of tumor recurrence, which has been linked to standard immunosuppression regimens. Everolimus is a mammalian target of rapamycin inhibitor that has been used for immunosuppression, but its effect on recurrence and survival in HCC patients with a high risk of tumor recurrence has not been examined. We compared long-term survival and cumulative recurrence in high-risk patients receiving everolimus-based immunosuppression after liver transplantation for HCC with an historic control group.

METHODS

The everolimus group comprised 21 patients receiving a liver transplant at our center from February 2005 to December 2010. The control group comprised 31 patients receiving a liver transplant from May 1994 to January 2005. All patients received cyclosporine or tacrolimus as initial post-transplant immunosuppression. Patients in the everolimus group switched to everolimus 2 weeks later.

RESULTS

There were no differences between the two groups in number of rejection episodes or of infectious or surgical complications. Five-year survival was 60.2% in the everolimus group and 32.3% in the control group (P = .05). Five-year cumulative recurrence rate was 61.3% in the control group and 41.3% in the everolimus group. Treatment with everolimus was identified as an independent predictor of longer survival (hazard ratio = 0.34; P = .02).

CONCLUSIONS

Patients receiving liver transplantation for HCC with a high risk of tumor recurrence may well benefit from everolimus-based immunosuppression, with no added risks of rejection or other post-transplant complications.

[Efficacy of short- and long-term efalizumab]

T cells play an important role in the immune system and in the inflammatory response that determines the development and maintenance of psoriasis plaques. Better understanding of the pathophysiology of this disease has led to the development of specific biological treatments aimed at patients with extensive psoriasis. Traditionally, psoriasis has been treated with drugs which, in spite of their efficacy, have a toxicity associated to their long-term use. Thus, they cannot be used safely, comfortably or efficiently in many patients. Efalizumab, a biological agent specifically and selectively directed towards blocking the key steps in the pathogenesis of psoriasis, has been shown to be effective and safe in the short and long term in the treatment of psoriasis in more than 15 phase I, II and III clinical trials. In this article, the results of efficacy at 12 weeks, 6 months and three years are reviewed. Efalizumab arises as an important addition to the dermatological pharmacopoeia for the long-term treatment of psoriasis.

Erythema figuratum in septic babesiosis

Babesiosis is a rare worldwide-distributed protozoal zoonosis caused by a haemoprotozoan of the genus Babesia, transmitted through bites of tick of the genus Ixodes. The first demonstrated case of human babesiosis in the world was discovered in Europe, in 1957. However, most of the cases were reported later in the north-east of the United States where Babesia microti has been the cause of over 300 cases of human babesiosis since 1969. In Europe, the most severe cases are observed in asplenic patients infected by a parasite of cattle, the Babesia divergens. Only two cases of babesiosis have been reported in Spain. We present a case of erythema figuratum associated to septic babesiosis in a non-splenectomized man, which is currently the third case of babesiosis in Spain.
