Disease Areas

At UCB, we fulfill our commitment to patients living with immunologic conditions by investing in scientific research to advance patient care in multiple disease areas.

Ankylosing Spondylitis

Patients with AS may experience stiffness and significant pain in the lower back and sacroiliac joints.4,5 Inflammatory back pain in AS generally worsens during periods of inactivity, especially at night, which can make it difficult for many patients to sleep well. In addition, morning stiffness lasting for at least 30 minutes is common in patients with AS.5 Extra-spinal involvement, including enthesitis, uveitis, dactylitis, inflammatory bowel disease, and psoriasis, may also occur in these patients.6,7 Uncontrolled disease can lead to bone growth and spinal fusion, further restricting range of motion and resulting in spinal curvature.5,6 If the rib and joints/costovertebral joint are involved, patients may also experience difficulty breathing.4,6 Symptoms of AS have a major impact on patients’ quality of life, with pain and stiffness limiting their ability to work, exercise, and socialize.6,8,9

Although historically considered a disease that almost exclusively affected men, AS is increasingly being recognized in women.10,11 Women with AS may experience disease differently than men, reporting more joint pain, more peripheral involvement, and worse quality of life than men.10,12 Women may also have a slower progression of radiographic damage vs men.13 For women with AS who become pregnant, approximately 60% report persistent or worsening disease activity during pregnancy, and about 90% experience a flare within 1 year of giving birth.14

Crohn’s disease

Patients with CD can experience diarrhea, fever, nausea, abdominal pain, and severe weight loss.1 Chronic intestinal inflammation leads to progressive and destructive disease associated with damage to the mucosa.3 Over time, patients may develop stricturing or penetrating complications of disease, and more than 50% of individuals with CD require surgery within 10 years of diagnosis.4,5 The symptoms of CD may also result in significant anxiety, stress, depression, and isolation.1,6 Although CD does not significantly shorten life expectancy, patients are subject to a lifetime of suffering because of their symptoms, severe limitations on their social and family life, hospitalizations, surgeries, and an overall reduced quality of life.5,7,8

The prevalence of CD is approximately equal in men and women.9 Women with CD may experience disease differently than men, exhibiting lower quality of life and a greater risk of depression and anxiety.10 For women with CD who become pregnant, approximately one-third experience worsening disease activity.11 Studies have shown that active disease and flares during pregnancy are associated with negative pregnancy outcomes of preterm delivery and low birth weight infants.12 Furthermore, approximately 20% of women with CD flare within 6 months of giving birth.13

Non-radiographic Axial Spondyloarthritis

Patients with nr-axSpA may experience chronic lower back pain and inflammation of the sacroiliac joints.5,6 Additionally, lack of sleep and fatigue are commonly reported by these patients.7 Extra-spinal manifestations of disease, including uveitis, psoriasis, inflammatory bowel disease, dactylitis, peripheral arthritis, and enthesitis may also occur.7,8 Symptoms of nr-axSpA can have a significant impact on patients’ function, with patients experiencing reduced ability to work and lower work productivity.9 Patients may also experience anxiety, depression, and an overall reduced quality of life.10

Unlike in the related disease state of ankylosing spondylitis, the prevalence of nr-axSpA is similar in men and women.1-5,11 However, women can experience disease activity differently than men.12 Despite being less likely to experience radiographic progression, women experience greater functional impairments than men.12 Additionally, women with early disease have greater subjective disease activity and are more likely to have widespread pain than men.12,13 Women with definite sacroiliitis may also experience more fatigue and peripheral involvement than men.12 The overlap of clinical features with fibromyalgia can also complicate the diagnosis and treatment of axSpA in women, especially given the predominance of fibromyalgia in women.14

Plaque Psoriasis

PSO is characterized by well-defined, raised plaques with silvery scales.2,3 The plaques commonly occur on the scalp; extensor surfaces such as the elbows and knees; and the lower back.  Nail involvement is also common.2

The symptoms of PSO may negatively affect quality of life for people with this disease,4 increasing their risk of depression, anxiety, and suicidality vs the general population.5 Patients may also experience genital PSO, which can negatively affect many aspects of sexual health including sexual experience, frequency, and desire.6 

 

The prevalence of PSO is approximately equal in men and women.1, Seventy-five percent of women with PSO present before the age of 40, which implies that many of them are of childbearing potential.7 Women with PSO may experience disease differently than men, with a higher prevalence of psychological and sexual distress and a higher level of stigmatization.8,9 For women with PSO who become pregnant, 21% report no change in disease activity and 23% report worsening disease activity (when measured by a physician via change in body surface area, 55% of pregnant patients with PSO have no change and 15% have worsening disease activity.)10 Furthermore, 65% of women with PSO report worsening disease activity after giving birth (when measured by a physician, 41% have worsening disease activity).10

Psoriatic Arthritis

In addition to inflammation, swelling, and pain in the joints, patients with PsA may experience extra-articular manifestations, including enthesitis, dactylitis, uveitis, and inflammatory bowel disease.4 Importantly, PsA occurs in up to 30% of patients with psoriasis, and in 85% of patients, skin disease (ie, psoriasis) occurs before joint disease.5 If left untreated, PsA may result in persistent pain and inflammation, permanent joint damage, and disability.4,6 PsA is associated with a substantial disease burden negatively affecting physical function as well as patients’ ability to socialize due to embarrassment, self-consciousness, and/or depression.4 Although exercise is beneficial, patients with PsA may also be hesitant to exercise due to pain or stiffness.7

The prevalence of PsA is approximately equal in men and women.8 Women with PsA may experience disease differently than men.9 Women with PsA may experience more limitations in daily physical function, more severe fatigue, and worse quality of life than men.   For women with PsA who become pregnant, approximately 32% have worsening or ongoing high disease activity during pregnancy, and approximately 40% experience a flare within 1 year postpartum.10

Rheumatoid Arthritis

Although some patients may experience a mild illness with minimal joint damage, in most patients with uncontrolled disease activity, RA will follow a progressive course, leading to increasing degrees of joint destruction, pain, and functional decline.1 Patients may also experience fatigue, weight loss, and extra-articular involvement.1,4,5 These patients tend to be less productive at work or experience such severe symptoms that they are unable to work at all.5

The prevalence of RA is higher in women than in men: women are about 2.5 times more likely to develop RA. 6 Women with RA may also experience disease differently than men. Women with RA tend to have an earlier onset of disease, lower quality of life, and more depressive symptoms than men.6-8 For women with RA who become pregnant, approximately 47% experience persistent or worsening disease.9 A study has shown that women with RA who had severe disease had worse pregnancy outcomes (ie, preterm delivery and small for gestational age infants) than those who had mild or no disease.10 Furthermore, approximately 40% of women with RA flare within 6 months postpartum.11
