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.
Insights
Methotrexate liver injury in psoriasis patients is less common than believed, with diabetes and obesity as key risk factors. Most liver damage occurred at cumulative doses under 6,000 mg.
Area of Science:
- Dermatology
- Hepatology
- Pharmacology
Background:
- Psoriasis treatment guidelines recommend liver monitoring due to concerns about methotrexate hepatotoxicity.
- Emerging data suggests methotrexate may be less liver toxic than previously understood.
Purpose of the Study:
- To assess the frequency and progression of liver injury in patients with psoriasis treated with methotrexate.
- To identify risk factors associated with methotrexate-induced liver damage.
Main Methods:
- Retrospective chart review of 125 psoriasis patients treated between 1976 and 2005.
- Analysis of 278 liver biopsies to evaluate histology.
- Statistical analysis to determine associations between methotrexate dosage, treatment duration, and liver injury.
Main Results:
- Liver injury was observed but generally mild (71% Roenigk grade I).
- Obesity and diabetes were significant risk factors for liver injury.
- Liver histology did not change in 72% of patients with multiple biopsies; deterioration occurred in 25%.
Conclusions:
- Methotrexate-related liver injury in psoriasis patients is less frequent than previously assumed.
- Significant liver injury typically occurred at cumulative doses below 6,000 mg.
- Diabetes and overweight status are strongly correlated with methotrexate hepatotoxicity.
