This study looked at the risk factors of total hip arthroplasty (replacement) in patients with psoriasis.

Quote:

---

Objective:
Outcomes of total hip arthroplasty (THA) in patients with psoriasis have been poorly studied. This study was undertaken to assess whether patients with psoriatic arthritis (PsA) or those with cutaneous psoriasis (PsC) without evidence of inflammatory joint disease are at an increased risk for worse outcomes after THA as compared to patients with osteoarthritis (OA).

Methods:
Among subjects in a prospective THA registry, PsA and PsC cases were identified by International Classification of Diseases, Ninth Revision codes, and all cases were matched with patients with OA as controls. Analyses were performed to identify predictors of poor postoperative pain or function.

Results:
Of the 289 potential cases of PsA or PsC, 63 with PsA and 153 with PsC were validated. Self-report data were available postoperatively from 75% of PsA patients, 69% of PsC patients, and 94% of OA controls. In total, 51% of PsA patients and 56% of PsC patients were male, compared to 45% of OA controls (P = 0.04). Body mass index was higher in those with PsA or PsC (P = 0.002 versus controls). There were no differences in race or education between the 3 groups. PsA patients and PsC patients had more comorbidities than OA controls. PsA patients were more likely than PsC patients and OA controls to be current or previous smokers. Moreover, 54% of PsA patients were being treated with biologics or nonbiologic disease-modifying antirheumatic drugs, compared to 8% of PsC patients. There were no significant differences in pre- or postoperative Western Ontario and McMaster Universities OA Index scores for pain or function between the 3 groups. Short-Form 36 mental component summary scores were significantly better in the OA controls, both pre- and postoperatively (P = 0.006 and P < 0.001, respectively, versus PsA or PsC). EuroQol 5-domain health-related quality of life scores were significantly worse postoperatively for those with PsA or PsC (P < 0.0001 versus OA controls). In regression analyses, neither PsA nor PsC were risk factors for worse THA outcomes. Satisfaction with the outcomes of THA was similarly high among all 3 groups (P = 0.54).

Conclusion:
Neither PsA nor PsC are risk factors for poor outcomes after THA. This is important information to convey to patients with either PsA or PsC who are contemplating surgical intervention with THA.

Hello everyone , I'm Danny from Leeds in England, I've had p for 16 years and started on acitretin 7 weeks ago.. So far it's flared big time but my skins got smoother.. Is the drug working ? Would be glad of any feedback

hi,

ps suffer for 20 years+ (35 age) about 40% body when bad flares. Been using dovobet 10 years but led to blepharitis and rosacea.

if i was a dog they would put me down.

from midlands, uk, would love to share my lovely experience with others lol

Hello All I hail from Vancouver Island, am 54 years old and am very happy to have found this site..! I started this journey in my late 20's after a bout with an unusual strep infec., that was not diagnosed for some time, then guttate and finally trip to dermatologist.
Plaque psoriasis came after 3rd child in late thirties and has plagued me on an off ever since. Stress and traumatic events have been a part of every major outbreak.
Currently, it is the worst it has ever been (feet and legs) and joint pain. This last precursor; major financial change, back to school for a bit, job change, kids leaving home - qualify all this. Except - they are not ceasing or getting better as time goes on!!!! Nasty turn of events and left it some time assuming it would just ease up.
This time I believe menopausal hormone shifts are exacerbating, causing all added fun - both guttate and plaque, lol.
I have seen a new, very young dermatologist with hopes of current discussion regarding treatments etc... funny, ended up with a coal tar treatment to start. This is merely irritating everything, and next appt. is long away. SO - that is where I am at at this moment in time - thanks for reading

Ahh, and last but not least, my mum and grand dad had psoriasis as well...

This is an early view before publication from the Australasian Journal of Dermatology that suggests pine tar is an effective treatment with minimal safety risk for psoriasis and other skin problems.

Quote:

Pine tar is the end product of pine wood carbonisation following distillation using extreme heat.

An extensive literature search was conducted back to the 1950s for this review. Pine tar has been used in medicine for more than 2000 years to treat a range of skin conditions because of its soothing and antiseptic properties.

Pine tar should not be confused with coal tar, which has been produced from coal for approximately a hundred years. Pine tar is thought to exert its effect by reducing DNA synthesis and mitotic activity, which promotes a return to normal keratinisation. In addition, pine tar has been shown to be antipruritic, anti-inflammatory, antibacterial and antifungal. These properties make pine tar suitable for the topical treatment of eczema, psoriasis, seborrhoeic dermatitis and other dry, itchy, flaky or inflamed skin conditions. Topical products available over-the-counter in Australia today contain up to 2.3% pine tar, and come in several different formulations that can be used on the entire body, including the face. Modern day pine tar is manufactured with increased purity to eliminate toxic phenol and carcinogenic components, which have been of concern in the past. Primary irritation is uncommon.

In conclusion, the long experience with topical pine tar therapy and its worldwide usage, together with the evidence presented in this review, suggests that pine tar is an effective treatment with minimal safety risk.

Has anyone been swimming with Psoriasis? It's honestly been so long since I've been that I cant remember if it affects it or not

Hello i started on fumaderm a few weeks ago and after some advice please.

The stage I am at just started the second week of the blue 120mg tabs I am taking first tab at 7 am with other meds.

The second I decided to take with dinner at 7 pm . from 4 pm on Monday started suffering from the run's but no pain.

Suffered all throughout the night and stomach pains from 4-5 am . 

Up til now I haven't seemed to have suffered from side effects.

Questions.

1. How can I tell it's the fumaferm or a bug ? As someone had bug last week at work.

2. What's the best times to take fumaderm to avoid side effects.

Any advice would be very helpful.

Thanks

Following on from the report about Benepali getting a positive opinion from CHMP Benepali biosimilar gets positive opinion from CHMP Biogen have announced they have been granted marketing authorization in the European Union (EU).

Quote:

Biogen has been granted European Commission (EC) approval for BENEPALI® , an etanercept biosimilar referencing Enbrel®i. BENEPALI has been granted marketing authorization in the European Union (EU) for the treatment of adults with moderate to severe rheumatoid arthritis (RA), psoriatic arthritis, non-radiographic axial spondyloarthritis and plaque psoriasis. Biogen intends to make BENEPALI available for patients in the coming weeks.

BENEPALI is the first etanercept biosimilar referencing Enbrel to be approved in the EU, making it the first subcutaneous anti-TNF biosimilar available there. Anti-TNF’s are the largest component of the EU biologics market, accounting for approximately $10 billion of all biologics sold there.ii

“The approval of BENEPALI is a significant step forward for patients and physicians, and an important milestone for Biogen as we bring to market the first product from our biosimilar pipeline,” said Alpna Seth, Ph. D., Senior Vice President and Global Head of the Biosimilars Business Unit at Biogen. “As a biotechnology pioneer, Biogen is proud to translate our heritage and expertise in biologics to biosimilars. BENEPALI, as the first etanercept biosimilar referencing Enbrel approved in the EU, can help expand access to treatment options for people affected by chronic inflammatory conditions.”

The EC approval was based on a robust preclinical and clinical data package submitted to the European Medicines Agency by Samsung Bioepis. The data in the preclinical submission leveraged sophisticated molecular analytics, technical development and manufacturing expertise. Confirmatory data from well-controlled, head-to-head Phase 1 and Phase 3 clinical trials compared BENEPALI to its reference product Enbrel.iii, iv The 52-week, double-blind, Phase 3 study randomized 596 patients with moderate to severe RA despite methotrexate therapy, across more than 70 sites in 10 countries to receive BENEPALI or Enbrel in a 1:1 ratio. Analysis of the primary endpoint showed that BENEPALI had equivalent efficacy to Enbrel, as shown by an ACR20 response at week 24 of 78.1% in the BENEPALI arm versus 80.3% in the Enbrel arm. Further analysis at 52 weeks confirmed comparable efficacy as shown by an ACR20 response of 80.8% in the BENEPALI arm versus 81.5% in the Enbrel arm. The safety profile of BENEPALI was comparable to that of Enbrel throughout the study.

“For more than 15 years anti-TNF therapies have revolutionized the care and outlook for patients living with chronic inflammatory diseases such as RA. However, access to these highly-effective treatments has been restricted by high costs," said Professor Peter Taylor, MA, FRCP, Ph. D., Norman Collisson Professor of Musculoskeletal Sciences, Kennedy Institute of Rheumatology, University of Oxford. "The development of biosimilar drugs is a welcome solution to help alleviate some challenges with access. The newly-approved treatment BENEPALI has similar quality, efficacy, and a comparable safety and immunogenicity profile to Enbrel.”

I read some time ago that there is a short term cure for psoriasis that your doctor could prescribe if you were going on holiday soon for example. I can't remember now what it is called. can anyone help?

Following on from Europe giving the go ahead for Cosentyx to treat psoriatic arthritis the FDA have now given it the go ahead in the U.S

Quote:

---

Novartis announced today that the US Food and Drug Administration (FDA) has approved Cosentyx® (secukinumab) for the treatment of two new indications - adults with active ankylosing spondylitis (AS) and active psoriatic arthritis (PsA). AS and PsA are both life-long, painful and debilitating inflammatory diseases that affect the joints and/or spine. If not treated effectively, both conditions can lead to irreversible joint and/or spinal bone damage caused by years of inflammation.

Cosentyx is the first in a new class of medicines called interleukin-17A (IL-17A) inhibitors to treat both AS and PsA. The two new indications follow the earlier FDA approval for Cosentyx in January 2015 to treat adult patients with moderate-to-severe plaque psoriasis, and European approval for AS and PsA in November 2015.

"These new approvals are a potential turning point for people living with ankylosing spondylitis and psoriatic arthritis in the US, as Cosentyx provides a novel and targeted way of inhibiting the inflammatory process of these two conditions," said David Epstein, Division Head, Novartis Pharmaceuticals. "The results from our studies have shown that the majority of patients treated with Cosentyx have a significant reduction in their signs and symptoms of ankylosing spondylitis and psoriatic arthritis, and show major improvements in their ability to undertake everyday activities."

In the US, it is estimated that up to 0.5% of the population have AS, and up to 1% live with PsA. If not treated effectively, these conditions can lead to irreversible damage to the spine and joints, causing life-long pain and disability that can have a negative impact on even simple tasks in life. There is an urgent unmet need for new medicines for these conditions. Currently many patients are dissatisfied with their treatments, and up to 40% do not respond sufficiently to anti-tumor necrosis factor-alpha (anti-TNFs) therapy.

The approvals are based on the efficacy and safety outcomes from four placebo-controlled Phase III studies, which included over 1,500 adult patients with AS or PsA that were biologic treatment naïve or had an inadequate response / were intolerant to anti-TNFs[1]. In the studies, Cosentyx met the primary endpoints achieving statistically significant improvements versus placebo in the signs and symptoms of AS and PsA, as measured by at least a 20% improvement in the Assessment of Spondyloarthritis International Society criteria (ASAS 20*) at Week 16, and a 20% reduction in the American College of Rheumatology (ACR 20) response criteria at Week 24, respectively. ASAS 20 and ACR 20 are standard tools used to assess clinical improvement in AS and PsA.

More than 9,600 patients have been treated with Cosentyx in clinical trials across multiple indications, and over 15,000 patients with psoriasis have already been treated in the post-marketing setting. The safety profile of Cosentyx was shown to be consistent with that seen in clinical trials across multiple indications.

This small study looked at plasma osteopontin and MIMT-CCA in psoriasis patients.

Quote:

---

Background:
The association between psoriasis and cardiovascular disease is well documented, but the underlying mechanisms remain unknown. The relationship between osteopontin and psoriasis has been studied. High serum levels of osteopontin are reported in psoriasis, with increased cardiovascular risk factors in these patients.

Objectives:
We evaluate the extent of subclinical atherosclerosis by measuring the mean intima–media wall thickness (MIMT) of the common carotid artery (CCA) in patients with psoriasis and assessing its correlation with osteopontin to identify vascular risk factors associated with psoriasis.

Methods:
Intima–media wall thickness of the CCA and plasma osteopontin were determined in 40 patients and 40 age- and sex-matched healthy control subjects.

Results:
Median serum osteopontin was significantly higher in patients with psoriasis than in healthy control subjects. Mean intima–media wall thickness of the CCA was positively associated with plasma osteopontin level (r = 0.47, P < 0.0001), body mass index (r = 0.62, P < 0.0001), age (r = 0.54, P < 0.0001), total cholesterol (r = 0.54, P < 0.0001), and triglycerides (r = 0.65, P < 0.0001).

Conclusions:
This study shows higher levels of plasma osteopontin and MIMT-CCA in psoriasis patients than in healthy controls. This is the first study to show a positive correlation between plasma osteopontin and MIMT-CCA.

Here's some more good news for people with psoriasis. Scientists at Trinity College Dublin have discovered the molecules that convert Interleukin-36 from its harmless form to its destructive one.

Quote:

---

Scientists at Trinity College Dublin have made an important breakthrough in understanding how an ‘immune SOS signal’, the protein Interleukin-36, serves an important role in switching on the immune system. The discovery may pave the way for the development of new therapies for treating psoriasis.

Interleukin-36 functions akin to an intruder alarm in the body, especially in the skin, switching on when injury and infection damages our tissues, and mobilizing all of the forces of the immune system to repair the damage. This process is called inflammation and causes the swelling and redness that we are all familiar with when we sprain our ankles or bump our heads.

Inflammation is generally a good thing as it is how the body heals wounds and shuts down infection. The problem is that some people, those with psoriasis, for example, switch on this alarm protein too readily and experience skin inflammation almost continuously. So, the question has been: How does interleukin-36 get switched on to send out the SOS signal?

Now, Professor Martin and recent Trinity PhD graduate, Dr Conor Henry, have discovered the molecules that convert Interleukin-36 from its harmless form to its destructive one, by removing a small piece of Interleukin-36, rather like pulling the pin out of a grenade.

These molecules, called proteases, are overactive in the skin of people that suffer from psoriasis, which suggests an entirely new way of treating this condition.

Indeed, scientists from the Martin laboratory have also discovered and patented inhibitors of the Interleukin-36 activating proteases, and hope to develop their strategy further in partnership with a Pharma or Skincare company.

Commenting on the findings, Professor Martin said: “This discovery is very exciting and we really hope to develop this approach into a new way of treating psoriasis.”

“We are very grateful for the support of Science Foundation Ireland, who funded this research. This work represents an excellent example of how basic research leads to fundamental breakthroughs in our understanding of how diseases arise. Without such knowledge, it would be very difficult to develop new therapies.”

The work was carried out in Trinity’s Department of Genetics by a team led by Professor Martin, which included Trinity PhD students Conor Henry and Graeme Sullivan. The Trinity team is internationally recognised for its work in the areas of cell death and inflammation.

Does anyone know of a treatment that helps with scalp psoriasis? I'm currently using capasal (I think it's called) and its has not helped in the slightest, it just smells bad. Any suggestions are more than welcome.

Thanks

5.2 Malignancies

In the controlled portions of clinical trials of TNF blockers, including SIMPONI, more cases of lymphoma have been observed among patients receiving anti-TNF treatment compared with patients in the control groups. During the controlled portions of the Phase 2 trials in RA, and the Phase 3 trials in RA, PsA and AS, the incidence of lymphoma per 100 patient-years of follow-up was 0.21 (95% CI: 0.03, 0.77) in the combined SIMPONI group compared with an incidence of 0 (95% CI: 0, 0.96) in the placebo group. In the controlled and uncontrolled portions of these clinical trials in 2347 SIMPONI-treated patients with a median follow-up of 1.4 years, the incidence of lymphoma was 3.8-fold higher than expected in the general U.S. population according to the SEER database (adjusted for age, gender, and race). Through Week 60 of the UC trials, there were no cases of lymphoma with SIMPONI. Patients with RA and other chronic inflammatory diseases, particularly patients with highly active disease and/or chronic exposure to immunosuppressant therapies, may be at higher risk (up to several fold) than the general population for the development of lymphoma, even in the absence of TNF-blocking therapy. Cases of acute and chronic leukemia have been reported with TNF-blocker use, including SIMPONI, in rheumatoid arthritis and other indications. Even in the absence of TNF-blocker therapy, patients with rheumatoid arthritis may be at a higher risk (approximately 2-fold) than the general population for the development of leukemia.
Rare postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL) have been reported in patients treated with TNF-blocking agents. This rare type of T-cell lymphoma has a very aggressive disease course and is usually fatal. Nearly all of the reported TNF blocker associated cases have occurred in patients with Crohn's disease or ulcerative colitis. The majority were in adolescent and young adult males. Almost all these patients had received treatment with azathioprine (AZA) or 6-mercaptopurine (6–MP) concomitantly with a TNF blocker at or prior to diagnosis. The potential risk with the combination of AZA or 6-MP and SIMPONI should be carefully considered. A risk for the development for hepatosplenic T-cell lymphoma in patients treated with TNF blockers cannot be excluded.

5.3 Congestive Heart Failure

Cases of worsening congestive heart failure (CHF) and new onset CHF have been reported with TNF blockers, including SIMPONI. Some cases had a fatal outcome. In several exploratory trials of other TNF blockers in the treatment of CHF, there were greater proportions of TNF-blocker-treated patients who had CHF exacerbations requiring hospitalization or increased mortality. SIMPONI has not been studied in patients with a history of CHF and SIMPONI should be used with caution in patients with CHF. If a decision is made to administer SIMPONI to patients with CHF, these patients should be closely monitored during therapy, and SIMPONI should be discontinued if new or worsening symptoms of CHF appear.

5.5 Autoimmunity

Treatment with TNF blockers, including SIMPONI, may result in the formation of antinuclear antibodies (ANA) and, rarely, in the development of a lupus-like syndrome. If a patient develops symptoms suggestive of a lupus-like syndrome following treatment with SIMPONI, treatment should be discontinued.

Following on from the news that Stelara is available to adolescents in Scotland. Health Canada has approved Stelara (ustekinumab) for the treatment of chronic moderate-to-severe plaque psoriasis in adolescent patients.

Janssen Inc. announced today that Health Canada has approved STELARA® (ustekinumab) for the treatment of chronic moderate-to-severe plaque psoriasis in adolescent patients (12 to 17 years) who are inadequately controlled by, or are intolerant to, other systemic therapies or phototherapies. Psoriasis is a chronic, inflammatory autoimmune disease, in which skin cells multiply faster than normal. This can result in raised, red, scaly patches that appear on the skin. While psoriasis can present at any age, approximately one-third of people living with the disease develop it before 20 years of age.

"The long-term efficacy and safety of STELARA® is well-documented in adults," says Dr. Ian Landells, MD, FRCPC, Clinical Associate Professor Department of Pediatrics and Medicine, Memorial University of Newfoundland and Clinical Chief of Dermatology, Eastern Health in St. John's, Newfoundland and Labrador. "It's encouraging that adolescents now have this effective treatment option to help manage their psoriasis, and one that has demonstrated good tolerability according to the CADMUS clinical study results."

The Health Canada approval of STELARA® for adolescents with psoriasis is based on data from the Phase 3 CADMUS study, designed to evaluate the efficacy and safety of STELARA® in patients aged 12 to 17 years with moderate-to-severe plaque psoriasis. The primary endpoint of the study was the proportion of patients achieving a Physician's Global Assessment of cleared/minimal (PGA 0/1) at week 12. This psoriasis assessment tool demonstrated that 69.4 per cent of patients who received standard dosing of STELARA® achieved PGA 0/1 at week 12.6

"The emotional and social impact of psoriasis can affect many aspects of day-to-day life," says Andrew Gosse, President, Canadian Psoriasis Network, who lives with psoriasis. "For adolescents living with the disease, this can be particularly devastating as they are in a pivotal time of life, when self-esteem and confidence can be fragile."

STELARA® blocks the action of two naturally occurring proteins called interleukin 12 (IL-12) and interleukin 23 (IL-23) that are believed to play a role in inflammatory conditions such as psoriasis and psoriatic arthritis. STELARA® received approval in Canada in 2008 for the treatment of adults living with psoriasis.

The Scottish Medicines Consortium (SMC) has completed its assessment of Stelara and advises NHS Boards and Area Drug and Therapeutic Committees (ADTCs) on its use in NHS Scotland in adolescent patients.

The advice is summarised as follows:

Following an abbreviated submission ustekinumab (Stelara) is accepted for restricted use within NHS Scotland.

Indication under review: Treatment of moderate to severe plaque psoriasis in adolescent
patients from the age of 12 years and older, who are inadequately controlled by, or are intolerant
to, other systemic therapies or phototherapies.

SMC restriction: continued treatment should be restricted to patients who achieve at least 75%
improvement in their Psoriasis Area and Severity Index (PASI 75) within 16 weeks.

started in March 2002 ended in September 2015 I did have a 2 year break after 9 or 10 years.
to cut a long story short the hospital did a different blood test than normal (it has a name but I have
forgotten it ) and they found my white blood cells were so low that I was in great danger of
becoming very ill.

Ahmedabad based Torrent Pharma enters New Year 2016 by announcing the launch of biosimilar Adalimumab in India under the brand name ‘Adfrar’.

Adalimumab is the most preferred therapy for the treatment of auto immune disorders and has wide applications like Rheumatoid Arthritis, Ankylosing Spondylitis, Psoriatic Arthritis, Ulcerative Colitis and Plaque Psoriasis. Adalimumab is the largest selling drug across the globe (innovator brand Humira has sales of 15 billion USD). Torrent’s brand ‘Adfrar’ will be the second biosimilar Adalimumab in the world.

Autoimmune disorders are growing ailments and Monoclonal Antibodies (MAb’s) are becoming mainstay of treatment, therefore launch of ‘Adfrar’ is a significant step towards fortifying its presence in MAb market.

Biosimilar Rituximab - ‘Toritz RA’ is already launched in Rheumatology segment and now with launch of biosimilar Adalimumab - ‘Adfrar’, Torrent presence in this segment will get a major fillip, making it a significant player in this super speciality.

‘Adfrar’ will be available as Pre Filled Syringe of 40mg. Torrent will promote this biosimilar to Rheumatologists, Gastroenterologists and Dermatologists pan India, for which three separate super specialty task force have been introduced. Around 100 highly trained professionals are employed in these Greenfield divisions.

This super speciality team, besides promoting biosimilar Adalimumab – ‘Adfrar IB’ to Gastroenterologists, will also cater to the advanced therapy needs in Hepatology. Torrent has launched new generation Hep C Antiviral Sofosbuvir – ‘Sofocruz’, a combination of Sofosbuvir + Ledipasvir - ‘Sofocruz LP’ and Daclatasvir – ‘Daclacruz’. Moreover, the company has also launched Hep B Antiviral Tenofovir – ‘Tenocruz’.

Torrent is already marketing biosimilar Rituximab ‘Toritz’ in Oncology segment, while a super specialty division for Nephrology launched in 2014 is marketing biosimilar Darbepoetin alpha - ‘Darbatitor’.

Regarding the expected business from these biosimilars, Executive Director - Marketing of Torrent Pharma Mr.Ruchir Modi said that since inception, its focus was never with business intent alone, rather it is a by product. Its purpose has always been to launch specialty niche products to address unmet medical needs arising from major life threatening diseases and reach out to maximum number of patients to offer cost effective treatment with latest quality drugs. He further added that with introduction of these new super specialty divisions, Torrent Pharma now covers most of the specialties and in near future plans to enter Urology and Opthalmology segments to cover the therapy gaps with strategic fit products.

Hi, My name is Stephen.

    I came across your site looking for information about NICE and what you think may happen to the drug Otezla.

I visited my specialist on Friday after being on the drug for the past 3 months only to find out that, even though I can stay on it for the next 9 months because it was a free 12 month trial, it may be denied funds.

Has anybody else been on this drug ?

Thank you.

This study looked at the prevalence of metabolic syndrome (MBS) in Lebanese patients with psoriasis.

Quote:

Background:
Psoriasis is a chronic inflammatory disease that affects not only the skin but also other organs as well. Genetic factors play an important role in individual predisposition. Lately, a positive association has been confirmed between psoriasis and metabolic syndrome (MBS), in western as well as in Middle Eastern countries.

Aim:
Assess the prevalence of MBS in Lebanese patients with psoriasis and the differential effect according to types and disease severity.

Methods:
This was a case-control study including 150 psoriasis patients and 150 age- and gender-matched controls admitted to the dermatology clinics at the American University of Beirut-Medical Center, a tertiary care center in Beirut. Psoriasis severity was assessed by the Psoriasis Area Severity Index (PASI). Blood samples were collected from fasting subjects and tested for glucose, HDL cholesterol, triglycerides, and C-reactive protein (CRP). Multivariate binary logistic regression models were built to assess the relationship between MBS and psoriasis, after adjustment for smoking as a possible confounding variable.

Results:
Patients with psoriasis were two times more likely to have MBS as compared to controls (35.3% vs 18.0%, P < 0.001) with an odds ratio (OR) of 2.4. All components of MBS were more prevalent in psoriasis patients than in controls. PASI score was greater in patients with MBS than those without MBS (10.5 ± 11.5 vs. 7.0 ± 8.1, P = 0.05). MBS prevalence tended to be higher in the inverse type than in others (52.2% versus 32.3%; P = 0.06) and in patients with nail pitting versus those without (45.3% vs. 28.2%; P = 0.03).

Conclusions:
This was the first study to assess the prevalence of MBS in Lebanese subjects with psoriasis and, to our knowledge, the first study that showed a higher likelihood of MBS in patients with inverse psoriasis and with nail pitting.
