The development of autoimmune diseases may be influenced by hormonal, immunomodulatory, and metabolic pathways. Prolactin (PRL), ferritin, vitamin D, and the tumor marker tissue polypeptide antigen (TPA) were measured in autoimmune diseases: systemic lupus erythematosus (SLE), systemic sclerosis (SSc), rheumatoid arthritis (RA), polymyositis (PM), dermatomyositis (DM), multiple sclerosis (MS), autoimmune thyroid diseases, and antiphospholipid syndrome. Hyperprolactinemia (HPRL) was detected in 24% of PM patients, in 21% of SLE patients, in 6.7% of MS patients, 6% of RA patients, and in 3% of SSc patients. Hyperferritinemia was detected in 23% of SLE patients, 15% of DM patients, 8% of MS patients, and 4% of RA patients. The patients had relatively low levels of 25 OH Vitamin D: the average results (mean +/- SD) were between 9.3 +/- 4.4 to 13.7 +/- 7.1 ng/mL in the different diseases, while the 25 OH Vitamin D concentrations less than 20 ng/mL are regarded as deficient. TPA levels were in the same range of the controls, elevated only in SLE. HPRL, hyperferritinemia, hypovitaminosis D, and TPA levels did not correlate with SLE activity elevated levels of rheumatoid factor or anti-CCP antibodies in RA. HPRL, hyperferritinemia, and hypovitaminosis D have different immunological implications in the pathogenesis of the autoimmune diseases. Preventive treatment with vitamin D or therapy for HPRL with dopamine agonists, may be considered in certain cases. Hyperferritinemia may be used as an acute-phase reactant marker in autoimmune diseases mainly SLE. TPA may be used to indicate the tendency for malignancies.

Antibodies to cyclic citrullinated peptides (anti-CCP) are highly specific for the diagnosis of rheumatoid arthritis (RA) with a marginal increased prediction of the disease. In this study, we aimed to investigate the relation of the presence of anti-CCP with clinical manifestations and disease activity in a cohort of RA patients. A total of 61 RA patients were included in this study. Data of disease-related parameters such as duration of disease, medications, degree of pain (visual analog scale, VAS), disease activity score 28 (DAS-28) and health assessment questionnaire (HAQ) were recorded. Laboratory workup included erythrocyte sedimentation rate (ESR), plasma C-reactive protein (CRP), rheumatoid factor (RF), anti-CCP, complete blood count and anemia parameters. Anti-CCP positivity was associated with higher scores of DAS-28, longer duration of morning stiffness, serum RF positivity and low levels of serum ferritin, while it was not associated with disease duration, VAS, HAQ, ESR, CRP and hemoglobin.

The aim of this study was to find the prevalence of anti-cyclic citrullinated peptide (anti-CCP) in patients with familial Mediterranean fever (FMF) and to examine the relationship between anti-CCP and joint findings. We measured the serum levels of the anti-CCP antibodies in patients with FMF (n = 55) and healthy controls (n = 43). Serum levels of rheumatoid factor (RF), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), fibrinogen, ferritin, erythrocyte sedimentation rate (ESR), and white blood cell (WBC) were also measured in all the samples. Fibrinogen, ferritin, erythrocyte sedimentation rate (ESR), and RF levels were normal in the patient and the control groups (P > 0.05). There was a significant difference in anti-CCP between the patient and the control groups (P = 0.008). There was a positive correlation between arthritis and anti-CCP (P = 0.001). In patients without arthritis, there was no significant relationship between abdominal pain or fever and anti-CCP (P > 0.05). Anti-CCP levels increased in FMF patients with arthritis independent from acute phase reactants such as CRP, ESR, and fibrinogen. We conclude that in patients who are under investigation for arthritis, the ones with positive anti-CCP and negative RF, may be examined for FMF. In addition, we also conclude that it is very likely that FMF patients with anti-CCP antibodies will have signs of arthritis. On the other hand, it is possible that long-term follow-up of the FMF patients with anti-CCP antibodies may reveal the eventual development of inflammatory joint disease.

Objective: Adult-onset Still's disease (AOSD) is a clinical entity with heterogeneous etiology. We have encountered patients with AOSD who had severe polyarthritis and who fulfilled the classification criteria for rheumatoid arthritis (RA); however, most patients with AOSD typically exhibit mild arthritis. In this study, we proposed two clinical subsets of AOSD and investigated the clinically significant characteristics of the two subtypes. Methods: We retrospectively analyzed 71 consecutive patients with AOSD. We reviewed the medical records of all patients who were followed up for more than 2 years. We classified all the patients with AOSD into the following 2 subsets: an RA subtype for patients who met the criteria for RA according to the American College of Rheumatology and a non-RA subtype for patients who did not meet the criteria for RA. Results: Our results indicated that the non-RA subtype was accompanied by severe inflammatory complications, including pleuritis and hemophagocytic syndrome. In addition, the serum ferritin and serum IL-18 levels were significantly higher in patients with the non-RA subtype than in those with the RA subtype. Interestingly, only 1 patient with the RA subtype had anti-CCP antibodies, and 1 non-RA subtype patient had rheumatoid factor. These findings distinguish these patients from patients with true RA. Conclusions: There were two subsets of patients with AOSD in the examined population. Patients with high levels of IL-18 or ferritin presented with severe systemic inflammatory disorders (the non-RA subtype), and patients with low levels of IL-18 or ferritin developed severe arthritis (RA subtype).
