Female patients are less satisfied with biological treatment for psoriasis and experience more side-effects than male patients: results from the prospective BioCAPTURE registry

BACKGROUND

Female sex has been reported as a predictor for treatment discontinuation with biological therapies for psoriasis, although reasons remain unclear. It can be hypothesized that lower satisfaction with biological treatment in women might add to the lower drug survival rates.

OBJECTIVES

To identify possible differences in satisfaction with biological treatment between female and male patients using the Treatment Satisfaction Questionnaire for Medication (TSQM).

METHODS

Data of psoriasis patients treated with biologics were obtained from the prospective, multicentre, daily-practice BioCAPTURE registry. Longitudinal TSQM data were analysed by linear mixed models. Relevant patient characteristics were incorporated as possible confounding factors. Post hoc analysis of adverse events was performed in order to investigate differences between sexes.

RESULTS

We included 315 patients with 396 corresponding treatment episodes (137 adalimumab, 90 etanercept, 137 ustekinumab, 24 secukinumab and 8 infliximab). Almost forty per cent of the patients were female. Women had significantly lower baseline PASI scores (P = 0.01). Longitudinal analyses demonstrated lower TSQM scores for 'side-effects' (P = 0.05) and 'global satisfaction' (P = 0.01) in female patients compared with male patients over 1 year of treatment. Women reported more relevant adverse events in the context of biologic treatment compared to men (rate ratio 1.79; P < 0.001), with more fungal (rate ratio 2.20; P = 0.001) and herpes simplex infections (rate ratio 3.25; P = 0.005).

CONCLUSIONS

This study provides a prospective, longitudinal analysis of treatment satisfaction with biologics in female and male patients with psoriasis. Women were slightly less satisfied with treatment regarding side-effects and global satisfaction. Differences in treatment satisfaction and side-effects might add to the fact that women discontinue biological treatments more often.

Psoriasis treatment with etanercept and efalizumab: clinical strategies influencing treatment outcome

BACKGROUND

Multiple trials have been conducted in which the safety and efficacy of different biological therapies for psoriasis have been studied. However, the treatment course in clinical practice is different from the setting in which trials are conducted.

OBJECTIVES

The evaluation of the efficacy, safety and adverse events of etanercept and efalizumab treatment in daily practice and the investigation of interfering clinical strategies that could be of influence on treatment outcome.

METHODS

A prospective cohort consisting of 101 patients with high-need psoriasis was followed for 2 years and analysed. Patients were treated with etanercept or efalizumab between February 2005 and May 2007. Efficacy, safety and adverse events were investigated. Furthermore, all accompanying factors of which an influence on treatment efficacy outcome was suspected were registered, including treatment interruptions, dosage adjustments and combinations of therapies.

RESULTS

Etanercept and efalizumab treatment was effective and safe in most patients. However, in many cases the treatment course was characterized by unsatisfactory efficacy (83%), necessitating combination therapies or dosage adjustments. Treatment interruptions occurred in 56% (etanercept 2x50 mg group), 84% (etanercept 2x25 mg group) and 10% (efalizumab-treated patients).

CONCLUSIONS

Treatment of high-need psoriasis patients in daily practice is highly different from treatment courses in clinical trials. Frequently applied clinical strategies such as treatment interruptions, dosage adjustments and combinations of treatments influence treatment outcome in routine treatment in comparison with randomized controlled trials. Information about treatment with these new drugs in daily clinical practice is important for adjusting treatment schedules and guidelines.

Dermatologists’ Adherence to the Guideline of the Dutch Society of Dermatology and Venereology with Respect to the Treatment with Methotrexate for Severe Chronic Plaque Psoriasis: Results from a Dutch Survey

BACKGROUND

In 2003, the Dutch guideline 'Photo(chemo) therapy and systemic therapy for severe chronic plaque psoriasis' was established.

OBJECTIVES

To document how closely this guideline is followed in clinical practice with respect to the methotrexate (MTX) treatment and to formulate recommendations to adjust the guideline.

METHODS

A survey was conducted among Dutch dermatologists and residents in dermatology. The questionnaire assessed the knowledge of and the adherence to the guideline with respect to MTX treatment.

RESULTS

Fifty percent of the contacted dermatologists/residents responded. Fifty-two percent follow the guideline with respect to MTX. Liver biopsy and the frequency of blood investigations cause a discrepancy between guideline and reality. There is a lack of consensus between guidelines of the different specialisms concerning liver biopsy.

CONCLUSION

The need for liver biopsies in combination with the frequent check-ups and the lack of consensus between rheumatologists, hepatologists and dermatologists seem to restrict the adherence to the guideline.

Liver injury in long-term methotrexate treatment in psoriasis is relatively infrequent

BACKGROUND

Methotrexate-induced liver damage in psoriasis has led to dermatologic guidelines that stipulate monitoring of liver injury by means of serial liver biopsies. Recent literature data suggest that methotrexate may be considerably less hepatotoxic than previously assumed.

AIM

To evaluate prevalence and development of liver injury in methotrexate treated psoriasis.

METHODS

Retrospective chart review (1976-2005).

RESULTS

Hundred and twenty-five patients (F58/M67; mean age 45.0, SD 12.7 years) received a median cumulative methotrexate dose of 2,113 mg (range 180-20 235) over a median period of 228 weeks (range 16-1763). Two hundred and seventy eight liver biopsies were analysed and 71% were classified as Roenigk grade I, 14% as Roenigk II, 14% grade IIIa, 2% grade IIIB and 2% grade IV. Liver injury was not associated with cumulative dose, weekly prescribed dose, age or duration of treatment. Obesity and diabetes were significant risk factors for liver injury. A total of 68 patients had multiple biopsies, 3% improved, 72% did not change and in 25% liver histology deteriorated. The majority of cases (84%) that progressed to Roenigk 2 had a cumulative dose of 1,500-6,000 mg.

CONCLUSIONS

Methotrexate-related liver injury is less frequent than previously thought and mostly occurred at cumulative dose of <6,000 mg. Diabetes and being overweight are significantly correlated with liver injury.
