The BIPQ, which allows rapid assessment of IP and reveals gender differences in AR, is a convenient tool for use in routine clinical practice. Further investigation is needed to demonstrate how IP may influence patients' behavior in AR, treatment adherence and disease outcome.

INTRODUCTION:Systemic lupus erythematosus (SLE) and myasthenia gravis (MG) are autoimmune diseases that show some similarities: a higher incidence in young women, relapsing-remitting course and positive anti-nuclear antibodies (ANA). However, they are two different clinical syndromes, which can coexist or precede each other. Thymectomy is a therapeutic option for patients with severe MG or thymoma. There are many cases of SLE after thymectomy described in the literature, so the question arises whether thymectomy predisposes patients to SLE and what are imunopathogenetic mechanisms behind this process.CASE REPORT:We report a case of a patient who was diagnosed with SLE and secondary antiphospholipid syndrome (APS) 28 years after thymectomy for MG. Clinical picture of SLE was characterized by cutaneous and articular manifestations, polyserositis, lupus nephritis and immunological parameters showed positive ANA, anti-ds-DNA, excessive consumption of complement components, positive cryoglobulins. Clinical and laboratory immunological parameters for the diagnosis of secondary APS where also present. The patient was initially treated with glucocorticoids followed by mycophenolate mofetil. During one year follow-up patient was in a stable remission of SLE.CONCLUSION:Thymectomy for MG may predispose SLE development in some patients. Further studies are needed to better understand the connection between these two autoimmune diseases.

In differential diagnosis, Melkersson-Rosenthal syndrome diagnosis primarily refers to conditions of angioneurotic edema and hereditary angioedema, as well as granulomatous diseases such as sarcoidosis, tuberculosis and Chron's disease. It is necessary to follow-up these patients in view of monitoring the effects of the therapy and possible development of systemic granulomatous diseases.

Takayasu arteritis (TA) is an idiopathic chronic granulomatous vasculitis that affects aorta, its main branches and occasionally pulmonary arteries. It is more common in Asian persons, affecting predominantly young women. Clinical presentation is nonspecific at the beginning of the disease, while in the ischemic disease’s stage it depends on the territories affected. We present the case of a 26-year-old woman who was diagnosed as having TA. Multiple vascular abnormalities of aorta and its branches and severely reduced left ventricular function were present at the time of diagnosis. Immunosuppressive treatment consisting of prednisone and azathyoprine along with conventional heart failure therapy significantly improved her cardiac function

This case alerts to the need of careful examination of patients with SLE, collection of adequate cultures and evaluation of predisposition towards infections, before the introduction of immunosuppressants due to potentially fatal infection.
