Giant cell arteritis of the female genital tract: report of a case and review of the literature.

A 65-year-old female presented with constitutional symptoms of fever and weight loss with bilateral adnexal masses on physical examination. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed and subsequently revealed giant cell arteritis involving numerous small arteries in the ovaries, fallopian tubes, paraovarian and paratubal soft tissues, myometrium, and cervix. After surgery, the patient continued to have constitutional symptoms. Corticosteroid therapy led to a significant improvement and eventual resolution of symptoms. Several similar cases of giant cell arteritis of the female genital tract have been described, both with and without concomitant temporal arteritis. Implications for diagnosis and treatment are discussed.

PI3K/AKT signaling and systemic autoimmunity.

The phosphoinositide 3-kinase (PI3K)/Akt signaling axis plays an important role in cellular proliferation and growth signaling. With respect to the immune system, a growing body of data is helping to elucidate the role of this pathway in lymphocyte development, as well as to show how perturbations that lead to unregulated activation in this pathway may produce systemic autoimmunity or malignancy. Various knockout and transgenic murine models have been described for key mediators of this signaling pathway. Many of these models resulting in the activation of this pathway demonstrate features of systemic autoimmunity, linking this pathway to autoimmune disease. Here, we review recently described murine models that exhibit activated PI3K/Akt signaling and the potential role this pathway in autoimmune disease, and also discuss the therapeutic implications of these findings.

Transverse myelitis in systemic sclerosis.

BACKGROUND: Neurological involvement occurs rarely with systemic sclerosis (SSc). Only a few cases of transverse myelopathy have been reported in the setting of SSc. OBJECTIVE: To describe a patient with SSc who developed transverse myelitis that improved during a course of immunosuppression. RESULTS: A 30-year-old woman with SSc presented with subacute onset of bilateral lower extremity weakness and numbness. Results of magnetic resonance imaging and cerebrospinal fluid studies supported a diagnosis of transverse myelitis. The patient responded favorably to a course of corticosteroids and cyclophosphamide. No overlapping autoimmune disorders were evident. Clinical follow-up showed significant recovery, with resolution of radiological abnormalities. CONCLUSION: Transverse myelitis can occur as a rare manifestation of SSc and may respond favorably to immunosuppressive therapy.
