title: Familial Mediterranean fever. A review of the disease and clinical and laboratory findings in 105 patients.
abstract: BACKGROUND
  The diagnosis of familial Mediterranean fever still remains clinical, since no specific laboratory test exists, other than a molecular genetic test which is not widely available.
  
  
  OBJECTIVE
  To evaluate the clinical findings in 105 Turkish patients; to compare these findings with those in the literature; and to make a brief review of the disease.
  
  
  METHODS
  A total of 105 familial Mediterranean fever patients were evaluated either retrospectively (for those diagnosed before 1997), or prospectively (for those after 1997). A diagnostic criteria set was used in addition to the clinical and laboratory findings that can be seen in familial Mediterranean fever, including the newly described manifestations. Previously selected clinical and laboratory parameters were observed for three consecutive days.
  
  
  RESULTS
  Of our patients, 88.5% were of Turkish, 3.8% of Armenian and 7. 6% of Jewish origin. Family history was positive in 87 (82.8%) patients. Involved site was peritoneum in 97 (92%), joints in 45 (42.8%) and pleura in 19 (18%). Frequency of myalgia/arthralgia was 24.7%, and skin findings were observed in 16. 1% of patients. Splenomegaly, not related to amyloidosis, was present in 21 (20%) patients. Meningeal, retinal or ovarian/testicular involvement was not observed.
  
  
  CONCLUSIONS
  Identification of familial Mediterranean fever gene has led to the application of a molecular genetic test for the diagnosis of Familial Mediterranean Fever. Until genetic methods become widely available, diagnosis will remain clinical. Thus, awareness of various clinical forms and of the correct usage of diagnostic criteria in various patient populations is important.
