Psoriasis, Crohn disease (CD) and ulcerative colitis (UC) are chronic inflammatory disorders with overlapping genetic architecture. However, data on the frequency and risk of CD and UC in psoriasis are scarce and poorly understood.
To investigate the association between CD and UC in patients with psoriasis.
All Danish individuals aged = 18 years between 1 January 1997 and 31 December 2012 were linked in nationwide registers. Psoriasis severity was defined in two models: hospital visits and medication. Incidence rates per 10 000 person-years were calculated, and incidence rate ratios (IRRs) were estimated by Poisson regression.
In the total cohort (n = 5 554 100) there were 75 209 incident cases of psoriasis, 11 309 incident cases of CD and 30 310 incident cases of UC, during follow-up. The adjusted IRRs (95% confidence intervals) of CD were 1·28 (1·03-1·59), 2·56 (1·87-3·50), 2·85 (1·72-4·73) and 3·42 (2·36-4·95) in patients with mild psoriasis, severe psoriasis (hospital), severe psoriasis (medication) and psoriatic arthritis, respectively. Similarly, the adjusted IRRs of UC were 1·49 (1·32-1·68), 1·56 (1·22-2·00), 1·96 (1·36-2·83) and 2·43 (1·86-3·17), respectively. The 10-year incidence of CD was 2-5 per 1000 patients and of UC 7-11 per 1000 patients, depending on psoriasis severity and the presence of psoriatic arthritis. Additionally, an increased risk of incident psoriasis was found following CD or UC.
We observed a psoriasis-associated increased risk of CD and UC, which was higher in severe psoriasis, and an increased risk of psoriasis in patients with inflammatory bowel disease. Increased focus on gastrointestinal symptoms in patients with psoriasis may be warranted.
Psoriasis, psoriatic arthritis, and uveitis are inflammatory disorders with significant overlap in their inflammatory pathways. Limited evidence is available about the relationship between psoriatic disease and uveitis.
To investigate the potential bidirectional relationship between psoriatic disease, including psoriasis and psoriatic arthritis, and uveitis.
We performed a nationwide cohort study of the Danish population from January 1, 1997, through December 31, 2011. We included 74,129 Danish patients with psoriasis who were 18 years or older during the study period. Patients were identified through administrative registries, and information on age, sex, socioeconomic status, medication, and comorbidity was obtained using individual-level linkage of administrative registers. We performed data analysis from January 27 through March 4, 2015.
Diagnosis of mild or severe psoriasis or psoriatic arthritis for uveitis risk and diagnosis of uveitis for the risk for psoriasis or psoriatic arthritis.
Diagnosis of uveitis, mild psoriasis, severe psoriasis, or psoriatic arthritis. We calculated incidence rates (IRs) and estimated IR ratios adjusted for potential confounders using Poisson regression.
We identified 74,129 cases of psoriasis and psoriatic arthritis and 13,114 cases of uveitis. The IRs (95% CIs) for uveitis were 2.02 (1.99-2.06), 2.88 (2.33-3.56), 4.23 (2.40-7.45), and 5.49 (3.36-8.96) for the reference population and those with mild psoriasis, severe psoriasis, and psoriatic arthritis, respectively. In the reference population, these IRs (95% CIs) were 9.37 (9.30-9.45), 1.12 (1.10-1.15), and 1.04 (1.01-1.06), and in patients with uveitis, these statistics were 15.51 (12.92-18.62), 2.66 (1.72-4.13), and 4.25 (3.00-6.01) for mild psoriasis, severe psoriasis, and psoriatic arthritis, respectively. Adjusted IR ratios (95% CIs) for uveitis were 1.38 (1.11-1.70 [P?=?.02]), 1.40 (0.70-2.81 [P?=?.34]), and 2.50 (1.53-4.08 [P?
Psoriasis is one of the most common chronic skin diseases. The author presented results from a qualitative study focusing on patients with severe psoriasis in an acute phase and their experience of living with the disease. Twenty-two hospitalized patients with psoriasis were interviewed in depth. The interviews were consecutively analyzed according to grounded theory methodology. Bodily suffering emerged as a core variable in the data. Bodily suffering includes the following categories: the visible body, staying on an even keel, coping with an all-consuming disease, and social vulnerability. The results of this study indicate that the criterion for the management of soriasis should be the patients' own perception of the consequences of the disease.
We examined overall and specific cancer risks among Swedish subjects who had been hospitalised one or more times for psoriasis. A database was created by identifying such patients from the Swedish Hospital Discharge Register and linking them with the Cancer Registry. Follow-up of patients was carried out from the last hospitalisation through 2004. A total of 15 858 patients were hospitalised for psoriasis during 1965-2004, of whom 1408 developed cancer, giving an overall standardised incidence ratios (SIRs) of 1.33. A significant excess was noted for squamous cell skin cancer, and for cancers of the upper aerodigestive tract, oesophagus, stomach, liver, pancreas, lung, kidney and bladder as well as non-Hodgkin lymphoma. Many of these may reflect the effects of alcohol drinking and tobacco smoking. Patients with multiple hospitalisations showed high risk, particularly for oesophageal (SIR 6.97) and skin (SIR 4.76) cancers.
Mitogen response of peripheral blood lymphocytes with phytohemagglutinin (PHA), conconavalin A (Con A), pokeweed mitogen (PWM), and purified protein derivative (PPD) was studied in 32 patients with psoriatic arthritis (PsA). Results were compared with those obtained from a control group with rheumatoid arthritis (RA) and another group of normal subjects. The PHA, Con A, and PWM responses were depressed in the PsA group. The degree of depression of the mitogen response was comparable to that observed in the group of patients with active RA. Sequential studies done in a small group of PsA patients revealed that the mitogen response paralleled disease activity. Improvement of disease activity was followed by increased mitogen response.
BACKGROUND: The aim of the present study was to describe the clinical characteristics of a population of psoriatics sampled from a patient organisation and not from hospitals or out-patient clinics. Furthermore, we wanted to compare siblings with and without psoriasis regarding the occurrence of other diseases. METHODS: At the end of 1991, we initiated a project which aimed to study genetic factors leading to psoriasis. Firstly, we sent questionnaires to all the members of the Swedish Psoriasis Association. We then examined 1,217 individuals (570 with psoriasis) from 310 families, in their homes in the southern part of Sweden. All the available family members were examined clinically and asked about the course of the skin disease and the occurrence of other diseases. The eight hundred members of the proband generation were divided into two groups, with or without psoriasis, and their clinical features were compared. RESULTS: Most individuals in this study population had a mild form of psoriasis. The siblings with psoriasis had joint complaints significantly more frequently than their siblings without the skin disease and those with joint complaints had more widespread skin disease. Among the other studied concomitant diseases (iritis, heart or hypertension disease, endocrine disease, inflammatory bowel disease and neurological disease), we were not able to find any difference. Seventy-seven of 570 persons were found to be in remission (13.5%). Females had a mean onset 2.5 years earlier than males. We were not able to find any correlation between the extent of the skin disease and age at onset. Twice as many persons with joint complaints were found among those with psoriasis than among those without, 28% versus 13%. Almost half (48%) the psoriatics who also had joint complaints had psoriasis lesions on their nails. Endocrine disorders were found in 9% of those without any allele for Cw6, but only in 1% of those who had Cw6. In fact, none of 183 Cw6 carriers had diabetes, as compared to the population prevalence of 3-5% in Sweden. CONCLUSION: With the exception of joint complaints, persons with psoriasis, collected from a patient organisation, did not have an increased frequency of (studied) co-existing diseases.
In conclusion, this thesis demonstrated an association between inflammatory dermatological diseases, i.e. psoriasis and hidradenitis suppurativa, and the metabolic syndrome putting these two patient groups at cardiovascular risk. Therefore, it is recommended as a minimum to screen hidradenitis and psoriasis patients attending in/outpatient clinics for the metabolic syndrome aimed at prevention of cardiovascular disease. The increased risk of metabolic syndrome adds to the range of well-known disease-related burdens e.g. the physical skin symptoms, the psychological impact thereof, and other co-morbidities, thus highlighting that both hidradenitis and psoriasis patients require general medical attention beyond the skin.
