A real-world, non-interventional, prospective study of the effectiveness and safety of apremilast in bio-naïve adults with moderate plaque psoriasis treated in the routine care in Greece - the 'APRAISAL' study.

BACKGROUND: Real-world data in patients with moderate psoriasis treated with apremilast is limited. OBJECTIVES: To evaluate the effectiveness and safety of apremilast in bio-naïve patients with moderate psoriasis in real-world clinical settings. METHODS: This was a 52-week multicenter, observational, prospective study of adult outpatients with moderate psoriasis {[10% < body surface area < 20% or 10 < psoriasis area severity index (PASI) < 20] and 10 < dermatology quality of life index (DLQI) < 20} initiated on apremilast ≤7 days before enrollment. Missing data were imputed using the last observation carried forward method. RESULTS: A total of 287 eligible patients (median age: 54.2 years; median psoriasis duration: 9.8 years) were consecutively enrolled. At baseline, the median DLQI and PASI scores were 12.0 and 11.8, respectively. The 52-week DLQI ≤ 5 and PASI75 response rates were 68.3% and 61.0%. At 52 weeks, 70.8% and 72.7% of the patients shifted from moderate/severe/very severe to clear/minimal scalp and palmoplantar psoriasis involvement, respectively; the pruritus severity state improved in 67.2%. The 52-week Kaplan-Meier estimated drug continuation rate was 85.3%. The adverse drug reaction rate was 19.9%. CONCLUSIONS: Apremilast is a safe and effective treatment for bio-naïve patients with moderate psoriasis and specific psoriasis manifestations.

Effectiveness and safety of apremilast in biologic-naïve patients with moderate psoriasis treated in routine clinical practice in Greece: the APRAISAL study.

BACKGROUND: Apremilast is an oral phosphodiesterase-4 inhibitor indicated for patients with moderate-to-severe chronic plaque psoriasis and active psoriatic arthritis. OBJECTIVES: To examine the effectiveness of apremilast on Dermatology Life Quality Index (DLQI), Psoriasis Area and Severity Index (PASI) and nail, scalp and palmoplantar involvement, when administered prior to biologics. METHODS: This 52-week real-world study included biologic-naive adults with moderate psoriasis (psoriasis-involved body surface area 10% to <20%, or PASI 10 to <20 and DLQI 10 to <20). Apremilast was initiated ≤7 days before enrolment. Data from the first 100 eligible patients who completed 24 weeks (W24) of observation (or were prematurely withdrawn) are presented in this interim analysis using the last-observation-carried-forward imputation method. RESULTS: Eligible patients (mean age: 49.9 years; 71.0% males; median disease duration: 8.0 years) were consecutively enrolled between April and October 2017, by 18 dermatology specialists practising in hospital outpatient settings in Greece. Baseline DLQI (median: 12.0) and PASI (median: 11.7) scores improved (P < 0.001) at all postbaseline timepoints (Weeks 6, 16 and 24; W24 median decreases: 9.0 and 9.4 points respectively). At W24, DLQI ≤5, DLQI 0 or 1, and PASI-75 response rates were 63.0%, 25.0% and 48.0% respectively. The Nail Psoriasis Severity Index score in patients with baseline nail involvement (n = 57) decreased at all postbaseline timepoints (P < 0.001; W24 median decrease: 20.0 points). At W24, 50.0% and 51.7% of patients with baseline scalp (n = 76) and palmoplantar (n = 29) involvement respectively achieved postbaseline Physician's Global Assessment (PGA) score of 0 or 1 if baseline score was ≥3, or 0 if baseline score was 1 or 2. The adverse drug reaction rate was 21.0% (serious: 2.0%). CONCLUSIONS: These interim results indicate that through 24 weeks, apremilast improved quality of life and reduced disease severity in biologic-naive patients with moderate plaque psoriasis, while demonstrating safety consistent with the known safety profile.

Hypertrophic cardiomyopathy in systemic sclerosis. A report of two cases.

We describe two patients with diffuse systemic sclerosis (SSc) where the echocardiogram revealed asymmetric hypertrophy of the interventricular septum with signs of subaortic obstruction consistent with hypertrophic obstructive cardiomyopathy. Hypertrophic cardiomyopathy is associated with the human lymphocyte antigen (HLA DR3), and this may provide a possible link with SSc, as this HLA phenotype is common in the latter condition. However, further studies should examine whether a true association exists.

Concomitant angioimmunoblastic T-cell lymphoma and low grade B-cell lymphoproliferative disorder.

The presence of a rearranged immunoglobulin gene, in addition to the expected T-cell receptor gene rearrangement, is a frequent, albeit poorly understood, finding in the setting of angioimmunoblastic lymphadenopathy. A case of an angioimmunoblastic T-cell lymphoma is presented, where this apparently paradoxical dual gene rearrangement could be ascribed to the coexistence of an occult B-cell lymphoproliferative disorder.

Predicting response to chronic antihypertensive treatment with fosinopril: the role of angiotensin-converting enzyme gene polymorphism.

Insertion (I)/deletion (D) polymorphism of the ACE gene has been reported to be involved in various cardiovascular diseases. We investigated prospectively whether the response to the ACE inhibitor fosinopril varied according to the ACE genotype in previously untreated Greek hypertensive patients. After a 4-week observation period, fosinopril was administered at a dose of 20 mg daily and blood pressure was measured weekly for 6 months. The study population consisted of 104 hypertensive patients (46 male, 58 female). There were no differences in age, gender, body mass index, and pretreatment blood pressure levels among patients with the DD, ID, and II genotypes (n= 42, 30, 32, respectively). The reduction in systolic blood pressure was significantly greater in patients carrying the DD compared to II or ID genotypes (5.6 +/- 3.1 vs. 3.1 +/- 1.1 or 3.6 +/- 2.2, respectively; ANOVA, p < 0.05). The reduction in diastolic blood pressure was also significantly greater in DD hypertensives compared with II or ID (8.9 +/- 6 vs. 5.5 +/- 3.4 or 5.8 +/- 4, respectively; ANOVA, p < 0.05). The age and BMI were not correlated with the changes in SBP or DBP that were observed after fosinopril administration. In conclusion, the ACE gene genotype was shown to influence the response to fosinopril in hypertensive patients.

Resistance to activated protein C and FV leiden mutation in patients with a history of acute myocardial infarction or primary hypertension.

This study was designed to investigate both resistance to activated protein C (APC-R) and the factor FV Q506 mutation incidence in patients with a history of acute myocardial infarction (AMI) and patients with primary hypertension (PH), a high-risk group for arterial thrombosis. Eighty patients with a history of AMI (group A), 160 patients with a history of PH (group B), and 124 age-matched controls without arterial disease (group C) were studied. APC-R was determined using the Coatest APC Resistance Kit of Chromagenix, Sweden. The prevalence of the FV Q506 mutation was estimated by DNA analysis (Bertina method). The prevalence of the FV Q506 mutation was 20%, 13.75%, and 8% in groups A, B, and C, respectively (A v C P = .0466). The prevalence of APC-R was 47.5% in group A v 13% in group C (P < .0001) and 36.25% in group B v 13% in group C (P < .0001). The response to activated protein C expressed as mean value +/- SD was 2.05 +/- 0.33 in group A v 2.56 +/- 0.46 in group C (P < .05) and 2 +/- 0.22 in group B v 2.56 +/- 0.46 in group C (P < .05). These findings suggest that patients with a history of AMI or PH have a significantly increased incidence of both APC-R and FV Q506 mutation compared with the control group. These findings support the hypothesis that these anticoagulant defects may be risk factors for arterial thrombosis.

A comparative study of the pathogenic properties and transmissibility of a Greek and a Belgian encephalomyocarditis virus (EMCV) for piglets.

Thirteen susceptible piglets, aged 40 days, were divided into two groups and were experimentally infected either with a Greek (myocardial) or a Belgian (reproductive) encephalomyocarditis virus (EMCV) strain (total dose 5 x 10(6) TCID50, intramuscularly and intranasally). Six piglets were placed in the same rooms, 24 h later, as contact controls. The following criteria were studied: ante mortem: clinical signs, serum cardiac isoenzyme activities (CK-MB and LD-1), viraemia, nasal and faecal virus excretion and serological response. Post mortem (after death or euthanasia): gross lesions, virus isolation from tissues, RT-PCR, as well as histopathological and immunohistochemical findings. The Greek strain was more pathogenic, producing mortality, with high cardiac isoenzyme activities and pronounced macroscopic myocardium lesions. The Belgian strain was able to induce mild heart lesions, as detected only by cardiac isoenzyme activity and histopathologically. All contact pigs were infected, within the first 1-2 days of their introduction, that coincided with the period of viral excretion by the experimentally infected pigs (up to the 3rd day post infection). Disease was mild, with no mortality.

Elevated plasma immunoreactive leptin levels preexist in healthy offspring of patients with essential hypertension.

BACKGROUND: Plasma leptin levels and plasma insulin levels have been found to be elevated in patients with essential hypertension (EH) and have been suggested to be components of the metabolic syndrome. Increased heart rate (HR) may predict the development of EH in normal or borderline-hypertensive individuals. The aim of our study was to test the hypothesis that elevated plasma leptin and insulin levels as well as systolic blood pressure (SBP) and diastolic blood pressure (DBP) and increased resting HR preexist in the healthy offspring of patients with EH. METHODS AND RESULTS: Twenty-six (12 male, 14 female) healthy offspring of hypertensive patients, mean age 16 +/- 2.5 years and body mass index (BMI) of 21.5 +/- 2.8 kg/m(2) (group A), and 30 (14 male, 16 female) healthy offspring of normotensive patients, mean age 17 +/- 2.3 years and BMI of 21.9 +/- 2.4 kg/m(2) (group B), were studied. (The two groups were matched for sex, age, and BMI). Mean SBP, DBP, resting HR, plasma leptin, and plasma insulin levels (radioimmunoassay method) were determined in the whole study population. Mean SBP, DBP, and resting HR were significantly higher in group A than in group B (120 +/- 12 vs 112 +/- 9.5 mm Hg, 77 +/- 9 vs 72 +/- 7 mm Hg, 79 +/- 8 vs 75 +/- 5 beats/min, P <.01, P <.05, and P <.05, respectively). Plasma leptin and insulin levels were significantly higher in group A than in group B (9 +/- 5.06 vs 5.6 +/- 2.5 ng/mL and 20.11 +/- 11.3 vs 14.8 +/- 5.2 microIU/mL, P <.01 and P <.05, respectively). CONCLUSIONS: Our findings support the hypothesis that hyperleptinemia, hyperinsulinemia, and elevated blood pressure and resting HR preexist in the healthy offspring of patients with EH.

Hydrofluoric acid burns.

We observed seven patients who presented consecutively with hydrofluoric acid hand burns. The clinical characteristics of these patients and the course of their disease and treatment are reviewed. Dermatologists should be aware that a hydrofluoric acid burn constitutes a dermatologic emergency. Specialized treatment is required to prevent topical, system, and even lethal toxic effects.

Evaluation of the autoimmune response in leprosy.

Immunological responses to a panel of antigens were evaluated in 27 patients with lepromatous and 20 patients with tuberculoid leprosy and compared with 24 pulmonary tuberculosis patients, 25 systemic lupus erythematosus patients and 41 healthy blood donors. Some autoantibody specificities were extensively studied for the first time in mycobacterial infections. Striking immunoserological abnormalities were found in patients with lepromatous leprosy, particularly in those presenting with relapse. Inhibition assays were performed, providing a tool for further analysis of the binding range of specific anti-N.D.O. BSA antibodies and strengthening the suggestion of molecular mimicry reactions between cytoskeletal proteins, host stress proteins and Mycobacterium leprae antigens or stress proteins. A significant serological overlap between lepromatous leprosy and autoimmune diseases is indicated.
