The impressive anti-inflammatory effects of the tumor necrosis factor (TNF)alpha blockers etanercept and infliximab have led to their use in multiple inflammatory diseases besides their original indication, rheumatoid arthritis (RA). The well-studied clinical effects of both agents in RA are the reduction of signs and symptoms of joint inflammation as well as the arrest of bone destruction. Infliximab has also been Food and Drug Administration-approved in the treatment of Crohn disease; etanercept is now FDA-approved for juvenile chronic arthritis and psoriatic arthritis. Favorable initial clinical trials have been reported in other rheumatic diseases, including ankylosing spondylitis and adult Still disease. In addition, TNF alpha blockade is being studied in the treatment of uveitis, myelodysplastic syndromes, and graft-versus-host disease. Studies in sepsis and septic shock have identified small subsets of patients that may benefit from TNF alpha blockade, but broader use in septic patients has not improved survival. The TNF alpha blockers have had relatively infrequent serious side effects, especially compared with the immunosuppressive and cytotoxic agents otherwise employed to treat these diseases. Further studies of optimal dosing, combination with other therapies, and long-term benefits and side effects will emerge from future trials.

Sacroiliitis is the most pathognomonic and earliest manifestation of ankylosing spondylitis. We herein report a 28-year-old female patient who presented with sacroiliitis as an initial manifestation of acute myelogenous leukemia (AML). She had a 3-month history of anemia and walking difficulty. Bone marrow findings revealed an increase of blasts with trilineage dysplasia. Although she was initially diagnosed with myelodysplastic syndrome (MDS), blasts rapidly increased and AML developed 1 month after the diagnosis of MDS with Sacroiliitis. Induction chemotherapy failed to induce a complete remission of AML, but it did effectively treat the sacroiliitis. However, the sacroiliitis relapsed when the leukemia cells progressed thereafter. Oral corticosteroids helped ameliorate the sacroiliitis. She underwent bone marrow transplantation (BMT) from an HLA-identical sister during a nonremission period; however, the leukemic cells began to rapidly increase from day 30 after BMT. The close relationship between the occurrence of sacroiliitis and AML suggested that autoimmune sacroiliitis was a paraneoplastic phenomenon of AML in this patient. Although autoimmune disorders develop in a substantial number of MDS patients, they are rarely observed in de novo AML. No previous report has described sacroiliitis as the initial manifestation of de novo AML.

The authors report an unusual case of myelodysplastic syndrome (MDS) associated with ankylosing spondylitis (AS). A 40-year-old-man with MDS presented with chronic low back pain for 6 years. Four years ago, MDS was diagnosed during routine blood analysis for the work-up of his articular complaints. His initial articular complaints were attributed to extramedullary manifestations of MDS. Persistent low back pain with increasing intensity finally led the patient to seek medical attention. Radiograph of the pelvis showed bilateral asymmetric sacroiliitis. A diagnosis of AS was established on the basis of modified New York criteria. Although various autoimmune phenomena associated with MDS have been described, this is the first report of AS in the setting of MDS. Causal relationship between these two disorders is currently unknown. Increased risk of hematological diseases as well as AS in individuals with a positive HLA-B27 provides a feasible explanation for this rare observation.
