Suicide risk and depression in patients with psoriasis.

BACKGROUND: Psoriasis is associated with comorbid psychiatric conditions. However, its relationship with suicidality is not completely understood. The aim of this study was to analyze the prevalence and the correlates of depressive symptoms and suicide risk in patients with psoriasis. METHODS: Adult psoriatic patients referring to the Outpatient Service of the Sant'Orsola-Malpighi Polyclinic were enrolled. Depressive symptoms and suicidality were assessed using the Patient Health Questionnaire (PHQ-9) and section C of Mini-International Neuropsychiatric Interview (M.I.N.I. 5.0.0). Psoriasis was evaluated using the Psoriasis Area and Severity Index (PASI), Body Surface Area (BSA) and the Dermatology Life Quality Index (DLQI). RESULTS: The prevalence of depressive symptoms was 14.9% and that of suicidality 6.3%. PHQ-9 scores were higher in patients with moderate-to-severe psoriasis (PASI≥10, Mann-Whitney U Test=4014.5; P<0.001; BSA≥10, Mann-Whitney Test=3930.5; P<0.001) and poorer quality of life (Mann-Whitney Test=805.5; P=0.024). Moreover, PHQ-9 scores were higher in females (Mann-Whitney Test U=3612.5; P=0.008) and were unrelated to age (rs=-0.056, P=0.423). Conversely, suicide risk was significantly higher in younger patients (Mann-Whitney=744, P=0.013) and females (χ2=5.69, P=0.028), and was unrelated to psoriasis severity. CONCLUSIONS: Patients with moderate-to-severe psoriasis, especially females, should be screened for depression and suicidal ideation to support them with effective strategies to treat depressive symptoms.

Deferred time of delivery of biologic therapies in patients with stabilized psoriasis leads to a 'perceived satisfaction': a multicentric study.

OBJECTIVE: Thanks to their specificity of action, biologic drugs often lead to complete clearance of psoriatic lesions. In order to maintain its effectiveness, biological therapies cannot be discontinued. The aim of the study was to investigate the effect of widening the administration window of four biologic drugs, thus improving the quality of life of psoriatic patients and satisfying their desire to feel free from the disease, without loss of effectiveness. METHODS: We performed a multicentric cohort study considering patients with moderate-severe plaque psoriasis and/or arthropathic psoriasis treated with infliximab, adalimumab, etanercept or ustekinumab. The study group included patients with stabilized psoriasis in which the administration regimen of the biologic drug was deferred. The control group included psoriatic patients treated according the product monograph. RESULTS: The percentage of relapses in case of deferred administration intervals was comparable to that of standard administration intervals. The delayed administration modality got a good psychological consensus from the patients themselves, that reported a greater 'perceived satisfaction'. A consistent economic advantage was reported in case of prolonged administration intervals. CONCLUSIONS: The administration of biologic drugs with prolonged intervals maintains the same effectiveness as standard administration and produces a 'perceived satisfaction' in psoriatic patients.

Ultrasound patterns of localized cutaneous leishmaniasis and clinical correlations.

A single-center retrospective study reviewed the following sonographic features of 18 confirmed cases of localized cutaneous leishmaniasis to identify shared presentation patterns: echotexture, lesion borders, hypodermal involvement, soft-tissue changes, and vascular pattern. A second objective was to correlate these patterns with clinical characteristics, including sex, age, anatomical location, nodule vs. plaque presentation, raised borders, granulation tissue, swelling, hyperkeratotic crusting, disease onset, and healing time. Two main patterns were identified with high-frequency ultrasonography. The first pattern was characterized by a high level of inflammation and deep hypodermal involvement, while the second variant showed involvement limited to the dermis, with minimal inflammation. The "inflammatory pattern" showed ill-defined borders, mixed echotexture, prominent vascularity with central distribution, and was correlated with clinical signs of ulceration, granulation tissue, raised borders, and longer healing time (p < 0.05). The "pauci-inflammatory pattern" presented a well-defined structure with decreased echogenicity, reduced or absent vascularity with minimal soft-tissue changes, and was associated with a shorter healing time (p < 0.05).

The impact of psoriasis on marriage.

BACKGROUND: Psoriasis frequently affects partners and intimacy and sometimes leads to a break in relationships. The aim of this study was to evaluate the possible negative impact of psoriasis on married life using the Quality Marriage Index (QMI), a score used to assess marital satisfaction. METHODS: In this prospective case-control study married or divorced patients with moderate-to-severe plaque psoriasis were compared to a control group made up of married or divorced healthy patients without psoriasis. Each patient enrolled in the study was given the questionnaire to assess the QMI. RESULTS: Two hundred one patients were included in the study sample: 100 suffered from moderate-to-severe plaque psoriasis and the other 101 did not. A significantly higher number of psoriatic patients was divorced than patients without psoriasis. By analyzing the QMI questionnaire, patients with psoriasis scored lower than patients without psoriasis in all single questions and in the total QMI value. By assessing how much each question weighed in the QMI final score, a significant difference between the two groups of patients was found in questions 3 and 6: the first one regarding the strength of marriage weighed more in psoriatic patients, while the second one regarding the happiness of marriage weighed more in non-psoriasis patients. CONCLUSIONS: Psoriasis can contribute to marriage breakdown in affected patients. The concept of happiness seems to be greatly affected by the repercussions of psoriasis, while the strength of marriage plays a fundamental role in these patients.

Efficacy and safety of biosimilar rituximab in the treatment of pemphigus vulgaris: a single center experience of 12 cases.

OBJECTIVE: Rituximab, a chimeric monoclonal antibody that targets the CD-20 molecule on B-cells' surface, has led to significant advances in the treatment of autoimmune pemphigus in recent decades. The aim of the study was to assess the clinical efficacy as well as safety data for biosimilar rituximab with emphasis on the treatment of pemphigus vulgaris. METHODS: A total of 12 individuals with pemphigus vulgaris treated with biosimilar rituximab were followed for at least 1 year. We assessed patient characteristics, disease history, pemphigus disease area index (PDAI) score, anti-desmoglein (Dsg)1 and anti-Dsg3 antibody level, clinical response, and any adverse events during each clinical follow-up visit. We also recorded time to achieve complete remission, duration of complete remission and time to relapse. RESULTS: A consistent decrease in the PDAI score was observed (p<.0001), as well as a significant decrease of anti-Dsg3 values. In addition, the clinical response of this population confirmed that the equivalent is not inferior to Rituximab (p=.521). CONCLUSIONS: The introduction or the switch to Rixathon, a rituximab biosimilar, appears to be safe and may provide an opportunity to reduce health system costs because of its similarity to the reference drug in terms of safety and efficacy.

Does psoriasis influence female sexual dysfunction? A multicentric Italian case-control study.

BACKGROUND: Psoriasis has a significant impact on quality of life and affects the sexual sphere in 25-70% of patients. The aim of this study is to determine the prevalence of sexual dysfunction in female patients with psoriasis and to assess the possible correlation of sexual dysfunction with disease severity, genital involvement, age and some comorbidities. METHODS: In this prospective case-control study, all female patients with psoriasis followed at three Psoriasis Outpatient Services were divided into two groups depending on psoriasis severity assessed by the Psoriasis Area Severity Index. Both psoriatic patients and female controls without psoriasis were given the Female Sexual Function Index (FSFI) questionnaire. RESULTS: One hundred forty female patients with psoriasis were evaluated, 70 with mild disease and 70 with moderate-severe disease, and compared with 70 female controls without psoriasis. According to FSFI Score, prevalence of sexual dysfunctions was significantly higher in moderate-severe psoriatic patients compared to controls. Psoriatic women under the age of 46 presented lower FSFI scores than women over 46. No correlation between genital localization of psoriasis and worsening of sexual health was found. Diabetes mellitus and hypertension were significantly associated with sexual dysfunction, whereas the smoking habit did not significantly affect the sexual sphere of these patients. CONCLUSIONS: Sexual dysfunction should be routinely investigated in female patients with psoriasis in the case of moderate-severe disease due to its negative impact on quality of life, especially in younger women and in presence of diabetes mellitus and hypertension.

Therapeutic approaches and targets for treatment of autoimmune bullous diseases.

Autoimmune bullous diseases are a heterogeneous group of diseases characterized by the development of cutaneous and mucosal vesicles, blisters, and finally erosions. The common pathogenetic mechanism is the presence of autoantibodies targeting structural proteins of the skin and mucous membranes (demosomes and hemidesmosomes): in the case of pemphigus, the antigens are intraepidermal, whereas in the case of pemphigoid, dermatitis herpetiformis, and epidermolysis bullosa acquisita they are subepidermal. Mucosal involvement typically affects the oral and ocular mucosa, but in some cases, the upper airways or the upper digestive tract are affected. The burden on patients' lives could be severe due to the impairment of normal feeding or breathing. In other cases, they may represent paraneoplastic syndromes. Since autoimmune bullous diseases may result in significant morbidity and mortality, depending on the grade of cutaneous and mucosal involvement, a prompt therapeutic approach is mandatory and, in recalcitrant cases, may be challenging. The first line therapy consists of corticosteroids, both topical and systemic. Once remission or control of the acute phase is obtained, adjuvant therapies need to be introduced in order to spare the corticosteroid load and minimize side effects such as iatrogenic diabetes or osteoporosis. Herein, we describe all current therapeutic approaches to autoimmune bullous diseases, also including emerging therapies.

A peristomal plaque of sudden occurrence.

Koebner phenomenon regards the formation of a psoriatic lesion after a trauma, including tattoo, insect bite or other injuries. Although this manifestation is not specific for psoriasis, physicians should be aware because early recognition may be helpful in making the diagnosis when present.

Drug Intake and Actinic Keratosis: A Case-Control Study.

BACKGROUND: Actinic keratosis (AK) is a form of premalignant keratinocyte dysplasia. Recently, the role of photosensitizing drugs in the development of AK has been postulated. OBJECTIVE: This study evaluated a possible association between the use of photosensitizing drugs and the development of AK. A secondary aim was to identify a possible association between any medication other than those primarily examined and AK. METHODS: A single-center, case-control study assessed the cumulative drug exposure of 90 patients with AK and 90 controls visiting a dermatology service for other skin ailments. Before the visit, patients were interviewed to collect data on daily therapy and the lag-time of discontinued drugs within the last 2 years, and to record the drug's active ingredient, dosage, and duration of therapy. In addition, sociodemographic characteristics including age, sex, educational level, skin phototype, and cumulative sun exposure habits were gathered. RESULTS: By logistic regression, exposures to angiotensin II receptor blockers (ARBs) and antiplatelet agents were identified as independent risk factors for the development of AK. ARB intake was associated with AK only at high exposure (OR = 13.6; 95% CI, 2.0-93.8). The use of antiplatelet drugs was borderline, yet not significant, at low exposure (OR = 3.31; 95% CI, 0.86-12.7), but increased in a dose-dependent manner. The strongest correlation was found at the highest cumulative dose (>1100 dose unit-years (OR = 4.38; 95% CI, 1.16-16.6). CONCLUSIONS: High exposure to ARBs and antiplatelet agents may promote AK carcinogenesis in at-risk patients.

Squamous cell carcinoma superimposed on mucosal leishmaniasis in an HIV-positive patient.

Leishmaniasis is emerging as an important problem in immunosuppressed individuals, leading to overt clinical disease, atypical presentation, chronic course, and impaired treatment response. Moreover, it can affect unexposed regions and strikingly mimic other infectious disorders and a variety of neoplastic diseases, thus being easily misdiagnosed. Here, we report the case of an HIV-patient where both clinical picture and histopathological findings were consistent with mucosal leishmaniasis (ML). However, the worsening of the clinical picture after anti-leishmania treatment led to suspect a different diagnosis, and squamous cell carcinoma superimposed on ML and Human Papilloma Virus infection was ultimately diagnosed.

The Role of Trichoscopy in Keratosis Follicularis Spinulosa Decalvans: Case Report and Review of the Literature.

INTRODUCTION: Keratosis follicularis spinulosa decalvans (KFSD) is a rare, X-linked, hereditary disorder of keratinization, characterized by skin involvement and progressive scarring alopecia of scalp, eyebrows, and eyelashes. The diagnosis is helped by the particular clinical features, but pathology is mandatory. CASE PRESENTATION: We described a case of a female patient referred to the outpatient's hair consultation of our department, in which we performed trichoscopy as a very useful tool for the diagnosis, followed by pathology that confirmed KFSD. CONCLUSION: In our article, we underlined the importance of trichoscopy for the diagnosis of this hair disease, with also a review of the literature on diagnosis and treatment.
