Auditory System Involvement in Psoriasis

New-Onset Hidradenitis Suppurativa in Psoriasis Patients: A Multi-Center, Retrospective Cohort Study

BACKGROUND

Previous research has indicated a potential correlation between hidradenitis suppurativa (HS) and psoriasis (PSO), two chronic inflammatory dermatological diseases. However, there is a lack of comprehensive evaluations that consider a variety of clinical and demographic factors, and the risk of developing HS in PSO patients remains unclear. Our study aims to examine HS risk over time among PSO patients versus matched controls while considering the influence of confounders to provide insights into the potential link between these two diseases.

METHOD

In this multi-institutional cohort study using the TriNetX database, we matched 202,318 patients with PSO with an equivalent number of individuals without PSO, using propensity score matching. The study period extended from 1 January 2005 to 31 December 2018. We computed hazard ratios and their respective 95% confidence intervals (CIs) to evaluate the probability of HS manifestation over a period of 5 years in patients with PSO in comparison to those without PSO.

RESULTS

PSO patients demonstrated a consistently higher risk of developing HS than matched controls across all analytic models with the hazard ratios (HR) ranging from 1.43 (95% CI 1.30-1.56) to 5.91 (95% CI 2.49-14.04). Stratified analyses showed the increased HS risk was observed in both genders but only significant in those aged 18-64 years. Kaplan-Meier analysis indicated PSO patients had a higher cumulative probability of developing HS over time (HR 1.77, 95% CI 1.49-1.89).

CONCLUSIONS

PSO was associated with increased HS risk, highlighting the importance of considering HS as a potential comorbidity in PSO patients and may have implications for early detection, prevention, and management strategies for both conditions. Shared inflammatory pathways, genetic components, and skin dysbiosis may contribute. Further research should elucidate underlying mechanisms.

Evaluation of Auditory Functions in Patients with Psoriasis

Our study aims to evaluate the functions of the middle and inner ear and the efferent auditory system in psoriasis. Hearing thresholds, resonance frequency, otoacoustic emission amplitudes with and without contralateral acoustic stimulation, contralateral suppression levels were evaluated in 35 psoriasis patients and 40 controls. The air-conduction hearing thresholds of the patients were significantly higher than the controls at 125, 250, 500, 1000, 2000, 4000, and 12,000 Hz frequencies in the left ear, and 125, 250, 500, 1000, 2000, and 4000 Hz frequencies in the right ear, and the bone-conduction hearing thresholds of the patients were found to be significantly higher than the controls at all frequencies in the left ear, and 250, 500, 1000 and 2000 Hz in the right ear (p < 0.05). The resonance frequencies of patients were found to be significantly lower than the controls (p < 0.001). The emission amplitudes obtained with contralateral acoustic stimulation were significantly lower than without contralateral acoustic stimulation at 1 kHz frequency in both groups (p < 0.01). There was no significant difference in contralateral suppression levels of the two groups (p > 0.05). Our findings indicate that middle ear mechanics can be affected by psoriasis. There was no significant difference between psoriasis patients and healthy controls in terms of efferent auditory functions. There was a significant difference at limited frequency in hearing thresholds and emission amplitudes between the groups.

Hidradenitis suppurativa and psoriasis: the odd couple

Psoriasis and hidradenitis suppurativa are chronic inflammatory skin diseases that can develop together, negatively impacting on the patient's quality of life. We aimed to review the most up-to-date information regarding the epidemiology, pathogenesis, clinical presentation and possible therapeutical choices in patients with both psoriasis and hidradenitis suppurativa, thus linking these two autoimmune and autoinflammatory conditions. A narrative review of articles dating from 2017 to 2022 has been performed using the PubMed database. We analyzed the case reports and case series found in the literature regarding patients who suffered from both psoriasis and HS. Psoriasis arose before hidradenitis suppurativa in the majority of cases, while only a minority of them had hidradenitis suppurativa before psoriasis. Interestingly, some patients suffered from paradoxical hidradenitis suppurativa following biological therapy administered to treat the already present psoriasis. Lastly, new biological drugs have been marketed with great success for the outcome of psoriasis, but similar progress did not happen for hidradenitis. Novel therapeutic approaches and lines of research are needed for the treatment of these pathologies, even if concomitant, in order to improve patient's quality of life.

Association of Psoriasis With Hearing Loss: A Systematic Review and Meta-Analysis

BACKGROUND

The relation between psoriasis and hearing loss has been unclear.

OBJECTIVE

To investigate the association of psoriasis with hearing loss.

METHODS

We searched MEDLINE and Embase on 12th November 2022 for studies on the association between psoriasis and hearing loss. We conducted a random-effects model meta-analysis to calculate pooled mean difference (MD) in the pure tone thresholds, pooled odds ratio for sensorineural hearing loss, and pooled hazard ratio for sudden sensorineural hearing loss related to psoriasis.

RESULTS

We included 12 case-control/cross-sectional and 3 cohort studies with 202,683 subjects. Psoriasis was associated with hearing loss at 500 Hz (pooled MD 2.21, 95% CI (CI) 0.13 to 4.29), 1000 Hz (pooled MD 2.97, 95% CI 1.01 to 4.93), 2000 Hz (pooled MD 5.13, 95% CI 2.45 to 7.82), 4000 Hz (pooled MD 9.3, 95% CI 5.1 to 13.51), and 6000 Hz (pooled MD 11.04, 95% CI 5.05 to 17.03). Patients with psoriasis had increased odds for sensorineural hearing loss (pooled odds ratio 3.85, 95% CI 1.07-13.9) and risk for sudden sensorineural hearing loss (pooled hazard ratio 1.45; 95% CI 1.22-1.71).

CONCLUSION

Psoriasis is associated with hearing loss, especially at high frequencies.

Immunosenescence and Skin: A State of Art of Its Etiopathogenetic Role and Crucial Watershed for Systemic Implications

Immunosenescence is a complex multifactorial phenomenon consisting of wide-ranging remodeling of the immune system during the life span, resulting in an age-related qualitative-quantitative decline of immune cells and cytokines. A growing body of evidence in the international literature is highlighting the etiopathogenetic role of skin immunosenescence in the onset of various dermatologic conditions. Skin immunosenescence also serves as an interesting watershed for the onset of system-wide conditions in the context of allergic inflammation. Moreover, in recent years, an increasingly emerging and fascinating etiopathogenetic parallelism has been observed between some mechanisms of immunosenescence, both at cutaneous and systemic sites. This would help to explain the occurrence of apparently unconnected comorbidities. Throughout our review, we aim to shed light on emerging immunosenescent mechanisms shared between dermatologic disorders and other organ-specific diseases in the context of a more extensive discussion on the etiopathogenetic role of skin immunosenescence. A promising future perspective would be to focus on better understanding the mutual influence between skin and host immunity, as well as the influence of high inter-individual variability on immunosenescence/inflammaging. This can lead to a more comprehensive "immunobiographic" definition of each individual.

Otologic Manifestations of Psoriasis: A Systematic Review and Meta-Analysis

INTRODUCTION

Psoriatic skin lesions are often seen in the auricle and external auditory canal, but middle ear and inner ear manifestations are not easily identified. Several studies have indicated hearing loss and vestibular dysfunction with psoriasis, but the extent of association has not been well defined.

METHODS

A systematic search of PubMed, CINAHL, Scopus, and Cochrane Library was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Included studies described audiometric or vestibular assessment of psoriasis patients. Meta-analysis was represented with odds ratios (ORs) or mean difference (MD) with 95% confidence intervals.

RESULTS

A total of 13 studies with 589 psoriasis patients and 617 healthy controls were included. Age did not significantly differ between psoriasis patients (47.1 [12.4] yr) and healthy controls (45.4 [11.2] yr). Psoriasis area and severity index score was 9.9 (8.4), and body surface area scores was 7.9 (14.7). Pure-tone audiometry analysis showed higher mean hearing thresholds in psoriasis patients compared with healthy controls across all frequencies, with the greatest difference at 4000 Hz (MD, 7.70 [4.46-10.94]; p < 0.00001). Speech reception thresholds were worse with psoriasis (MD, 3.53 [1.56-5.49]; p < 0.0001). Abnormal stapedial reflex was more common in psoriasis (OR, 5.19 [1.68-15.99]; p = 0.004). Abnormal vestibular testing was more common in psoriasis for caloric testing (OR, 13.12 [2.88-59.84]; p < 0.0001). Two additional studies of 41,681 psoriasis patients and 80,273 healthy controls found that psoriasis patients were at higher risk for sudden sensorineural hearing loss (OR, 1.50 [1.25-1.80]; p < 0.0001).

CONCLUSION

Our study shows that psoriasis is associated with hearing loss and vestibular dysfunction, but clinical significance remains undefined. The trends noted in our study require more investigation, and the pathophysiologic mechanisms need to be defined.

Epidemiology of Psoriasis and Comorbid Diseases: A Narrative Review

Psoriasis is a chronic autoimmune inflammatory disease that remains active for a long period, even for life in most patients. The impact of psoriasis on health is not only limited to the skin, but also influences multiple systems of the body, even mental health. With the increasing of literature on the association between psoriasis and extracutaneous systems, a better understanding of psoriasis as an autoimmune disease with systemic inflammation is created. Except for cardiometabolic diseases, gastrointestinal diseases, chronic kidney diseases, malignancy, and infections that have received much attention, the association between psoriasis and more systemic diseases, including the skin system, reproductive system, and oral and ocular systems has also been revealed, and mental health diseases draw more attention not just because of the negative mental and mood influence caused by skin lesions, but a common immune-inflammatory mechanism identified of the two systemic diseases. This review summarizes the epidemiological evidence supporting the association between psoriasis and important and/or newly reported systemic diseases in the past 5 years, and may help to comprehensively recognize the comorbidity burden related to psoriasis, further to improve the management of people with psoriasis.

Mucocutaneous Manifestations of People Living with HIV in Current Antiretroviral Therapy Era

OBJECTIVE

It has been reported that approximately 90% of patients who are infected with human immunodeficiency virus (HIV) have various cutaneous symptoms that are related to the virus. This study aims to describe the cutaneous disorders that have developed in HIV-infected patients and to investigate the factors that may be related, such as relationships to drug use and CD4 counts.

METHODS

This cross-sectional study included people who were living with HIV and being followed by our hospital's infectious diseases clinic after they had been referred to the dermatology clinic because of skin lesions. These patients had been diagnosed with HIV by enzyme-linked immunosorbent assay tests and were included in the study if they were older than 18 years and had agreed to participate. Findings from detailed dermatological examinations were recorded, along with the patients' CD4 counts, the durations of their illnesses, and the treatments they received.

RESULTS

144 patients were included in the study. The most common mucocutaneous manifestation was seborrheic dermatitis, at 28.5% (n = 41). The mean CD4 count was 607.1 (min-max = 10.6-1982).The CD4 counts were divided into three groups in the study as follows: 22 (15.3%) patients with <200, 35 (24.3%) patients between 200 and 500, and 87 (60.4%) patients with >500. There were no statistical differences between these groups in terms of dermatological findings. Nevertheless, the highest rate of patients with three or more dermatological conditions was found among those with CD4 counts <200 (n = 11.50%).

CONCLUSION

Skin manifestations are common in patients who are HIV-positive; however, many skin disorders can be seen in HIV/acquired immunodeficiency syndrome (AIDS) patients whatever CD4 cell counts of these patients are.

Mutual Influence of Psoriasis and Sport

The link between psoriasis and sport is a controversial issue. The topic has been poorly investigated, and nowadays there are many unsolved questions, dealing with the role of psoriasis in influencing the sporting habits of patients and, vice versa, the impact of sport activity on course, severity and extent of the disease, with particular regard to the indirect benefits on cardiovascular risk and metabolic syndrome. Moreover, the role of physical activity on patients’ quality of life and the potential limitations on physical activity due to joint involvement have not been well elucidated until now. In this narrative review we will try to provide answers to these queries.

HIV-associated psoriasis: Epidemiology, pathogenesis, and management

People living with HIV (PLWH) are affected by a higher incidence skin disorders, which are often associated with high morbidity and mortality. In particular, psoriasis affects PLWH severely and for a longer time than the general population. Human immunodeficiency virus (HIV) infection is characterized by a progressive decrease in CD4⁺ T-cell count, and it could seem paradoxical that psoriasis exacerbations are more frequent in this subset of patients than the general population, even though it is commonly observed at any stage of infection. For a long time, there have been limited therapeutic choices for PLWH affected by psoriasis. The introduction of the combined antiretroviral therapy dramatically changed the natural course of both HIV and psoriasis in PLWH, leading to an improvement of quality and duration of life. However, the clinical severity of psoriasis in PLWH often requires the use of immunosuppressant drugs. Knowledge about their safety and efficacy are limited to case-reports, small case-series and studies, therefore their use has not yet entered the routine. Further studies are needed to determine if immunosuppressive drugs can be safely and effectively used in PLWH affected by psoriasis and other autoimmune disorders.
