Argentinean agid test for diagnosis of equine infectious anemia: six years of history

Equine infectious anemia (EIA) is a disease of high economic impact on the equine industry worldwide. Since horses are frequent travelers, EIA falls under strict regulatory control programs in many countries. In Argentina the national animal health authority (SENASA) states that all horses imported, moving within the country, or congregating at public assemblies must have a negative EIA report conducted within the previous 2 months. The agent causing EIA is a RNA virus from the Retroviridae family and its major capsid protein named p26 is the most immunogenic protein in the viral particle. Thus, the detection of specific antibodies directed to p26 is the aim of most diagnosis tests available in the world. The agar gel immunodifusion (AGID) is the officially accepted method to certify the diagnosis of EIA in Argentina. Since 2009 IncuINTA was working on the scaling up and production of the KIT AIE IDGA RP26, an Argentinean AGID test entirely developed in the laboratory containing a recombinant p26 protein to detect EIA antibodies in horses’ serum. Until 2015 IncuINTA produced two pilot batches and six commercial batches (one per year) containing from 24000 determinations in 2011 to 39600 determinations in 2015. Since the product was launched in 2011, the sales were increased 109%. Up to date we have placed on the market 170640 determinations. As expected, the number of laboratories buying the KIT AIE IDGA RP26 was also increasing through time being 26 in 2011 and 36 in 2015. This number of clients represents 17% of the 207 laboratories authorized by SENASA to diagnose EIA in Argentina. These laboratories are located mostly in Buenos Aires, Santa Fe, Entre Ríos, Formosa, La Pampa, Rio Negro, Cordoba, Corrientes, Salta and Tucum an provinces. Until 2009 there was no Argentinean EIA test available in our market being the imported ones very expensive. IncuINTA, which is a R&D laboratory, could scale up, produce and sell the KIT AIE IDGA RP26 during six consecutive years. After this success, IncuINTA perspective is to increase the number of batches each year to be able to attend the demand of most diagnosis laboratories in the country.Fil: Bok, Marina.

Consensus on the use of the fixed combination calcipotriol/betamethasone dipropionate in the treatment of plaque psoriasis.

Calcipotriol, a vitamin D analogue, and betamethasone dipropionate, a high potency corticosteroid, are complementary agents for the topical treatment of psoriasis vulgaris. Robust evidence on the efficacy and safety of their fixed combination has been provided by randomized, double-blind, controlled clinical trials involving more than 7000 patients with the ointment formulation in psoriasis of the body and more than 4000 patients with the gel formulation in scalp psoriasis. These trials have shown that the fixed combination ointment is more effective and better tolerated, not only than placebo, but also than calcipotriol and tacalcitol monotherapies. In addition, it has proved, in most instances, to be more effective than betamethasone and at least as well tolerated. The same applies to the gel for scalp and body psoriasis. Safety studies have excluded that repeated courses of treatment with the fixed combination for up to one year produce systemic effects. Studies have also shown that the fixed combination treatment improves quality of life to a significantly greater extent than calcipotriol, with the once daily regimen most appreciated by patients, in both active disease and recurrency. Because of the extensive evidence, American and European guidelines recommend the calcipotriol/betamethasone dipropionate fixed combination a

Hydradenitis suppurativa and inflammatory bowel disease: An unusual, but existing association

Inflammatory bowel disease (IBD) could be associated with several extra-intestinal manifestations (EIMs) involving musculoskeletal, hepatopancreatobiliary, ocular, renal, and pulmonary systems, as well as the skin. In the last years, hidradenitis suppurativa (HS) is acquiring an increasing interest. IBD, especially Crohn's disease (CD), is among the most reported associated diseases in HS patients. The aim of this paper is to give a brief overview of data showing a possible epidemiologic and pathogenetic association between IBD and HS. We performed a pooled-data analysis of four studies and pooled prevalence of HS in IBD patients was 12.8%, with a 95%CI of 11.7%-13.9%. HS was present in 17.3% of subjects with CD (95%CI: 15.5%-19.1%) and in 8.5% of UC patients (95%CI: 7.0%-9.9%). Some items, especially altered immune imbalance, are generally involved in IBD pathogenesis as well as invoked by HS. Smoking is one of the most relevant risk factors for both disorders, representing a predictor of their severity, despite, actually, there being a lack of studies analyzing a possible shared pathway. A role for inheritance in HS and CD pathogenesis has been supposed. Despite a genetic susceptibility having been demonstrated for both diseases, further studies are needed to investigate a genetic mutual route. Although the pathogenesis of IBD and HS is generally linked to alterations of the immune response, recent findings suggest a role for intestinal and skin microbiota, respectively. In detail, the frequent finding of Staphylococcus aureus and coagulase-negative staphylococci on HS cutaneous lesions suggests

Cyclosporine Regimens in Plaque Psoriasis: An Overview with Special Emphasis on Dose, Duration, and Old and New Treatment Approaches

Cyclosporine A (CsA) is one of the most effective systemic drugs available for the treatment of psoriasis, as evidenced by the results of several randomized studies and by a prolonged experience in dermatological setting. In clinical practice, CsA is usually used for the induction of psoriasis remission at a daily dose included in the range of 2.5–5 mg/kg and with intermittent short-term regimens, lasting on average 3–6 months. The magnitude and rapidity of response are dose dependent, as well as the risk of development of adverse events. Therefore, the dose should be tailored to patient’s needs and general characteristics and adjusted during the treatment course according to both the efficacy and tolerability. Some studies support the feasibility of pulse administration of CsA for a few days per week for both the induction and the maintenance of response in psoriasis patients. This paper will review the data on CsA regimens for plaque-type psoriasis and will focus the attention on dose, treatment duration, novel schedules, and role in combination therapies, including the association with biologicals

Health-related quality of life in psoriasis: an analysis of Psocare project patients

Psoriasis is a common, chronic, immune-mediated skin disorder that may be complicated by psoriatic arthritis in up to one-third of patients. Psoriasis treatments are increasingly effective, yet more expensive, thus requiring rational decision-making on interventional priorities. The ability to perform cost-utility analyses is hindered by the lack of algorithms that allow the inference of utility measures, like QALY, from specific dermatological health-related qualityof- life (HR-QoL) measures (e.g. Dermatology Life Quality Index [DLQI]). This study aimed to assess whether psoriasisrelated HR-QoL data (DLQI) could be used to obtain utility measures for use in economic analyses
