Apremilast for the treatment of palmo-plantar non-pustular psoriasis: A real-life single-center retrospective study.

Palmoplantar psoriasis (PP) is a type of psoriasis that involves the skin of the palms and soles and can present as hyperkeratotic, similar to the vulgaris psoriasis of the body. Apremilast, as an oral inhibitor of phosphodiesterase 4 (PDE4), is currently approved for the treatment of psoriatic arthritis and for moderate-to-severe psoriasis in adult patients who have not responded or have contraindications or do not tolerate other systemic treatments. We evaluated the efficacy and safety of apremilast in the treatment of non-pustular palmo-plantar psoriasis in a cohort of 12 patients. We found a clinical response of clear/almost clear palmoplantar psoriasis (PPPGA score 0/1) in 83.33% of our patients, at week 16. No significant safety issues were reported and none of our patients had to discontinue the drug.

Hidradenitis Suppurativa in a Large Cohort of Italian Patients: Evaluation of the Burden of Disease.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent, debilitating skin disease of the hair follicle that usually occurs after puberty with painful, deep-seated, inflamed nodules and sinus tracts in the apocrine gland-bearing areas of the body, most commonly the axillae and inguinal and anogenital regions, with a relevant impact on patients' quality of life (QoL). OBJECTIVE: To evaluate how the burden of HS disease impacts on patient well-being and working activities in a large Italian population over a period of 9 months. METHODS: A multicenter, prospective, epidemiologic cohort study was conducted in adult Italian patients with HS. HS severity was assessed through Hurley stage and HS Physician's Global Assessment (HS-PGA), clinical improvement by HS Clinical Response (HiSCR) and partial response, and disease burden through QoL questionnaires (HIDRAdisk, Skindex-16, Dermatology Life Quality Index [DLQI]), and Work Productivity and Activity Impairment - General Health (WPAI:GH). RESULTS: A total of 308 patients (56.2% women; mean age 35.2 ± 12.9 years) were enrolled in 27 dermatologic clinics. Men were older (37.4 years vs. 33.5), more smoking addicted (74.1% vs. 60.1%), and alcohol consumer (34.1% vs. 13.9%), while more women were obese (34.10% vs. 22.22%). At baseline, most patients had a Hurley severity stage of 2 (43.9%), a moderate HS-PGA score (57.1%), and poor QoL (HIDRAdisk: 65.7 ± 23.3, Skindex-16: 60.3 ± 26.9, and DLQI: 10.8 ± 8.1). Patients with more severe disease showed worse QoL. Mean values for the variables related to HS severity decreased during the study period. The achievement of HiSCR and partial response increased during the study. CONCLUSION: This study offers insight into the disease burden of HS in an Italian population. Our results underline the impact of QoL evaluation, also with the use of the HIDRAdisk, in clinical routine as a support to validated severity clinical and instrumental indexes for a "360-degree" assessment of HS patient's burden of disease.

Severe-Enduring Anorexia Nervosa (SE-AN): a case series.

BACKGROUND: Anorexia Nervosa (AN) poses significant therapeutic challenges, especially in cases meeting the criteria for Severe and Enduring Anorexia Nervosa (SE-AN). This subset of AN is associated with severe medical complications, frequent use of services, and the highest mortality rate among psychiatric disorders. CASE PRESENTATION: In the present case series, 14 patients were selected from those currently or previously taken care of at the Eating Disorders Outpatients Unit of the Maggiore Hospital in Bologna between January 2012 and May 2023. This case series focuses on the effects of the disease, the treatment compliance, and the description of those variables that could help understand the great complexity of the disorder. CONCLUSION: This case series highlights the relevant issue of resistance to treatment, as well as medical and psychological complications that mark the life course of SE-AN patients. The chronicity of these disorders is determined by the overlapping of the disorder's ego-syntonic nature, the health system's difficulty in recognizing the problem in its early stages, and the presence of occupational and social impairment.

Real-Life Effectiveness and Safety of Risankizumab in 131 Patients Affected by Moderate-to-Severe Plaque Psoriasis: A 52-Week Retrospective Study.

INTRODUCTION: Risankizumab is a humanized monoclonal antibody that selectively targets interleukin-23. It is approved for treatment of moderate-to-severe plaque psoriasis. We conducted a 52-week monocentric retrospective study to evaluate the effectiveness and safety of risankizumab in a real-life setting. METHODS: Our study included 131 adults with moderate-to-severe plaque psoriasis all treated with risankizumab for at least 52 weeks. Patient characteristics and PASI (Psoriasis Area and Severity Index) at each visit were recorded. The percentages of patients achieving 75%/90%/100% (PASI 75/90/100) improvement in PASI with respect to baseline were registered. RESULTS: At week 52, 93.9%, 78.6%, and 61.1% of patients achieved PASI 75/90/100, respectively. An absolute PASI ≤ 2 was reached by 90.8% at week 52. The higher body mass index and the presence of cardio-metabolic comorbidities did not interfere with the odds of reaching PASI 75/90/100 at each time-point. At week 52, comparable percentages of patients achieved PASI 100, regardless of the involvement of difficult-to-treat-areas. No significant safety findings were recorded and none of the patients had to interrupt the treatment because of adverse events. CONCLUSIONS: Our findings confirmed that risankizumab is a safe and effective therapeutic option for the treatment of a wide "real-life" cohort of patients with psoriasis.

Saliva Neurofilament Light Chain Is Not a Diagnostic Biomarker for Neurodegeneration in a Mixed Memory Clinic Population.

Neurodegeneration and axonal injury result in an increasing release of neurofilament light chain (NfL) into bodily fluids, including cerebrospinal fluid (CSF) and blood. Numerous studies have shown that NfL levels in CSF and blood are increased in neurodegenerative disorders and monitor neurodegeneration. Saliva is an easily accessible biofluid that could be utilized as a biofluid measurement of Alzheimer's disease (AD) biomarkers. In this study, for the first time, salivary NfL was measured and compared to plasma NfL in a consecutive cohort of patients referred to cognitive assessments. In two mixed memory clinic cohorts, saliva samples were taken from 152 patients, AD (n = 49), mild cognitive impairment (MCI) (n = 47), non-AD (n = 56), and also 17 healthy controls. In addition, 135 also had a matching plasma sample. All saliva and plasma samples were analyzed for NfL, and the association between saliva and plasma NfL and CSF levels of total tau (t-tau), phosphorylated tau (p-tau), and beta amyloid 1-42 (Aß42) were investigated. In total, 162/169 had quantifiable levels of salivary NfL by single molecule array (Simoa). No statistically significant differences were found in salivary NfL concentration across the diagnostic groups, but as expected, significant increases were found for plasma NfL in dementia cases (P < 0.0001). There was no association between saliva and plasma NfL levels. Furthermore, saliva NfL did not correlate with CSF Aß42, p-tau, or tau concentrations. In conclusion, NfL is detectable in saliva but does not reflect neurodegeneration in the brain.
