TOPLINE:
In patients with giant cell arteritis (GCA), intravenous methylprednisolone compared with oral glucocorticoids alone does not improve visual acuity and increases the risk for diabetes within the first year. Survival rates do not differ with these two treatments.
METHODOLOGY:
- Researchers conducted a population-based retrospective study at three centers in Sweden to assess the clinical characteristics, treatment-related toxicity, and mortality in patients with GCA who were receiving high-dose intravenous methylprednisolone.
- A total of 419 patients with biopsy-confirmed GCA (mean age at diagnosis, 75 years; 69% women) diagnosed from 2004 to 2019 were included.
- Patients were treated with either intravenous methylprednisolone (n = 111) at a dose of 500-1000 mg per day for 3 consecutive days or oral glucocorticoids alone (n = 308).
- Ischemic visual complications considered to indicate visual involvement were confirmed by an ophthalmologist, and data on visual acuity were collected from ophthalmologic clinic records at initial consultations and follow-up at 3-18 months.
TAKEAWAY:
- Despite a tendency toward improvement, no significant difference in visual acuity was observed with intravenous methylprednisolone compared with oral glucocorticoids.
- Patients treated with intravenous methylprednisolone had a higher risk for newly diagnosed diabetes within a year of GCA diagnosis (odds ratio [OR], 2.59; P = .01).
- The risk for diabetes remained elevated even after adjustment for the cumulative oral glucocorticoid dose at 3 months (adjusted OR, 3.30; P = .01).
- Survival rates did not significantly differ between the treatment groups over a mean follow-up of 6.6 years.
IN PRACTICE:
“In this study on the use of intravenous methylprednisolone treatment in GCA, we found no evidence of a beneficial effect in improving visual acuity or enabling more rapid tapering of the oral glucocorticoid dose,” the authors wrote. “The use of IVMP [intravenous methylprednisolone] was associated with an increased risk of diabetes during the first year compared with oral GC [glucocorticoid], raising questions about the value of IVMP in GCA treatment.”

The study, led by Hampus Henningson, Department of Clinical Sciences, Rheumatology, Lund University, Lund, Sweden, was published online in Rheumatology.
LIMITATIONS:
The retrospective nature of the study may have resulted in missing data and difficulty in accurately quantifying the cumulative glucocorticoid doses. The study did not validate the diagnoses of comorbidities but relied solely on diagnostic codes.
DISCLOSURES:
This study was supported by the Swedish Research Council, Swedish Rheumatism Association, Swedish Medical Society, Alfred Österlund’s Foundation, and King Gustaf V’s 80-year foundation. The authors declared no conflicts of interest.
