RESUMEN
Safety data with respect to kidney function during long-term treatment with cyclosporine A (CsA) in patients with atopic dermatitis is limited. Data on serum creatinine levels before, during and after CsA treatment were collected in a retrospective cohort of adult patients with atopic dermatitis. The median duration of treatment of 150 patients was 280 days (interquartile range 203-528 days). There was a significant, but not clinically relevant, increase in serum creatinine compared with the baseline level after 3 weeks of treatment with CsA and stabilization during the maintenance phase at the group level. Twenty-two (14.7%) patients had a greater than 30% increase in serum creatinine (cut-off point for clinically relevant change) compared with baseline. These patients were significantly older than the patients without a 30% increase (mean ± standard deviation age 41.4 ± 15.6 vs. 33.8 ± 11.7 years (p = 0.01)). During follow-up, all patients had a less than 30% increase in serum creatinine levels compared with baseline levels. At the group level serum creatinine levels during follow-up were not significantly different from baseline.

Synovial osteochondromatosis (SO) can occur idiopathic or secondary to osteoarthritis. SO can be easily diagnosed with plain film radiography and clinical findings. In case of disabling osteoarthritis, total knee arthroplasty and removal of all corpora libra are indicated. We present a 71-year-old woman with significant osteoarthritis and severe SO intra-articular and in the suprapatellar bursa of the right knee. Total knee arthroplasty, extraction of the loose bodies, and partial synovectomy were performed. During a 2.5-year follow-up, the patient regained full function of her affected knee and there was no recurrence of SO. We choose to present this case to show the extensiveness SO can occur in. Our advice is to remove all the loose bodies carefully to prevent damage to the prosthesis. During follow-up, special attention should be paid to prevent recurrence of SO. When recurrence is associated with rapid growth or destruction of joints, malignant reoccurrence must be considered.
