Impact of body mass index on retention rates of anti-TNF-alfa drugs in daily practice for psoriasis

Psoriasis is a chronic inflammatory skin disease which often requires life-long treatment.Our objective was to assess the role of the body mass index (BMI) on the retention rates of anti-TNF-alfa therapies in patients with moderate to severe plaque psoriasis.Retrospective observational study of psoriasis patients included in local databases of three public Italian hospitals. All patients, who received anti-TNF-alfa treatment in referral centers, were included. Only patients with at least 1-year follow-up were considered eligible. The outcome was the conservation of the treatment at 1 and 2 years of follow-up.194 patients were enrolled. 307 treatment courses with a minimum follow-up of 12 months and 263 with a follow-up of 24 months were analyzed. The proportion of patients receiving the same treatment at months 12 and 24 was 67.43% and 42.21%, respectively. The proportion steadily decreased with increased values of BMI.The overall efficacy of TNF-alfa inhibitors diminishes with time. The BMI affects the long-term survival rate of anti-TNF-alfa in psoriatic patients. A high BMI can be considered a potential predictor of drug discontinuation

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

Dermoscopy of necrobiosis lipoidica and granuloma annulare

Dermoscopy is traditionally used for the diagnosis of skin tumors, but it has also gained increasing interest as an adjunct in the clinical diagnosis of inflammatory skin diseases

Dermoscopy of cutaneous sarcoidosis

The clinical variability of cutaneous sarcoidosis (CS) often makes its correct diagnosis challenging. Although traditionally employed for the diagnosis of skin tumors, during the past years dermoscopy also gained increasing interest as an aid in the clinical diagnosis of inflammatory and infectious skin manifestations in general dermatology

May standard basal echocardiogram allow to obtain predictors of asymptomatic cardiac dysfunction in alcoholics?

Background: Long-lasting heavy alcohol intake has been progressively recognized as a leading cause of non-ischemic dilated cardiomyopathy, involving 10% of all people who use alcohol. It is of huge importance to identify the earliest markers of this dysfunction and it is known that the newest echocardiographic techniques such as speckle tracking may allow to do it. In this study we investigated if standard basal echocardiogram features allow to obtain predictors of asymptomatic cardiac dysfunction in alcoholics. Methods: A population of 80 consecutive asymptomatic alcoholics was enrolled. None presented history, signs or symptoms of cardiovascular disease. All of them underwent a conventional transthoracic mono-bidimensional and doppler echocardiography. Results: Our cohort did not present echocardiographic findings of increased left ventricular sizes, mass or relative wall thickness. Hence, a significant rate of systolic dysfunction was not found. Furthermore, statistical analysis displayed an inverse relationship between alcohol consumption and systolic pulmonary arterial pressure as well as between alcohol abuse and left atrium enlargement. This may be explained by a potential vasodilator mechanism occurring in the earliest stages of alcohol intake. On the contrary, a positive correlation with the E/A ratio was found, and this might be ascribed to state of high cardiac output determined by alcohol abuse. There were modes sex-related differences. Conclusions: This study has demonstrated that standard echocardiography may allow to predict cardiac dysfunction in asymptomatic alcoholics, and sex-related differences may be identified in this regard. These data need to be confirmed by further studies involving larger population
