RESUMO
AIM: Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory disease in the world. There are known triggers to initiate an FMF attack, yet potential effects of intrauterine devices (IUD) in women of reproductive age have not been evaluated before. METHOD: Consecutive female patients with FMF who ever used IUD over the age of 18 were enrolled. Female patients with FMF were sub grouped according to the type of IUD they use. FMF attack frequency, severity, duration, presence of dysmenorrhea, severity of dysmenorrhea, having attacks during menstruation before and after IUD use were questioned. Demographic and clinical data were collected from hospital database. RESULTS: When all patients with IUD use were evaluated, it was found that the frequency of attacks increased after IUD insertion at 3rd and 12th months (median [min-max] attack frequency at 3rd month, 1 (0-3) vs 1 (0-6), p = 0.002, median [min-max] attack frequency at 12th month, 2 (0-12) vs 3.5 (0-18), p = 0.028). Attack severity measured by VAS pain was also significantly increased. Attack duration and menstrual pain was similar before and after IUD use. Attack frequency at 3rd and 12th months, attack severity and menstrual pain was all increased significantly in Cu-IUD users, whereas none of these parameters deteriorated in LNG-IUD group. CONCLUSION: IUD use, especially Cu-IUD, may increase the frequency and severity of attacks in female patients with FMF. Clinicians may benefit from considering LGN-IUD if IUDs are preferred as contraception in women of childbearing age with FMF.

BACKGROUND: Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by persistent antiphospholipid antibodies (aPLs) with arterial and venous thrombosis and/or pregnancy morbidity. In recent years, several studies have highlighted the potential role of non-criteria aPL in diagnosing APS patients. AIM: This study aimed to determine the association of the presence of non-criteria aPL antibodies to the clinical and laboratory features of patients with a diagnosis of APS. METHODS: Eighty patients diagnosed with APS and under observation in the rheumatology clinic of Ankara City Hospital were assessed. Patient demographic and clinical features were meticulously recorded. Non-criteria antibodies tested in our center included antiphosphatidylserine IgA, antiphosphatidylserine IgM, beta 2 glycoprotein IgA, anti-cardiolipin IgA, antiphospholipid antibody IgG, and antiphospholipid antibody IgM. Antibodies from patients who were tested for at least one non-criteria antibody were documented. RESULTS: Out of 80 patients, 55 (68.8%) were tested for at least one non-criteria antibody, and 29 of those patients (52.7%) tested positive for at least one non-criteria antibody. The antiphospholipid antibody IgM and the beta 2 glycoprotein IgA were the most commonly tested non-criteria antibodies. Patients with non-criteria antibody positivity had a higher frequency of Ds DNA positivity and low complement (62.0% vs. 35.0%, p = 0.042; 69.0% vs. 38.0%, p = 0.023), respectively. In addition, positivity for anti-cardiolipin IgG and b2 glycoprotein IgG was significantly higher in the group positive for non-criteria antibodies (79% vs. 31%, p ≤ 0.001; 72.0% vs. 19%, p ≤ 0.001). There was no significant difference between the clinical features of patients with at least one positivity for non-criteria antibodies and those without. CONCLUSION: Systemic lupus erythematosus (SLE) is the most commonly associated disease with APS, being present in approximately 35% of cases [1]. Since the majority of the patient group in our study had APS that was secondary to SLE, non-criteria antibody positivity may be linked to the immunological activity of SLE. Large multicenter studies are necessary to investigate the clinical significance of isolated/combined positivity for criterion/non-criteria aPLs.

To investigate cancer incidence in patients with ANCA-associated vasculitis (AAV), compare it with the age/sex-specific cancer risk of the Turkish population, and explore independent risk factors associated with cancer. This multicenter, incidence case-control study was conducted using the TRVaS registry. AAV patients without cancer history before AAV diagnosis were included. Demographic and AAV-related data of patients with and without an incident cancer were compared. Standardized cancer incidence rates were calculated using age-/sex-specific 2017 Turkish National Cancer Registry data for cancers (excluding non-melanoma skin cancers). Cox regression was performed to find factors related to incident cancers in AAV patients. Of 461 AAV patients (236 [51.2%] male), 19 had incident cancers after 2022.8 patient-years follow-up. Median (IQR) disease duration was 3.4 (5.5) years, and 58 (12.6%) patients died [7 with cancer and one without cancer (log-rank, p = 0.04)]. Cancer-diagnosed patients were older, mostly male, and more likely to have anti-PR3-ANCA positivity. The cumulative cyclophosphamide dose was similar in patients with and without cancer. Overall cancer risk in AAV was 2.1 (SIR) ((1.3-3.2), p = 0.004); lung and head-neck [primary target sites for AAV] cancers were the most common. In Cox regression, male sex and ≥ 60 years of age at AAV diagnosis were associated with increased cancer risk, while receiving rituximab was associated with decreased cancer risk. Cancer risk was 2.1 times higher in AAV patients than the age-/sex-specific cancer risk of the Turkish population population, despite a high rate of rituximab use and lower dose of cyclophosphamide doses. Vigilance in cancer screening for AAV patients covering lung, genitourinary, and head-neck regions, particularly in males and the elderly, is vital.
