Objective: To identify any adverse effects of colchicine in a pediatric patients with familial Mediterranean fever (FMF)., Study Design: Clinical presentation, Mediterranean fever gene genotype, disease duration, colchicine dose, laboratory tests, and reported adverse effects in children with FMF were analyzed., Results: Of the 153 patients with FMF, 22 (14.4%) developed diarrhea during a follow-up of 4 years; the colchicine dose was reduced to control this symptom in only 4 patients. In 18 (11.8%) patients, a mild transitory increase of transaminases (45-158 IU/L) was found during a follow-up of 1 year. Blood cell counts and kidney function tests were normal in all patients. No correlation was found between the adverse effects and patient's age, disease onset, treatment duration, or any of the clinical characteristics of the disease., Conclusion: Colchicine is a safe drug in the treatment of children with FMF, even in infancy. The only significant adverse effects are diarrhea (in a small number of patients), which can be controlled by a decrease in the colchicine dose and transitory elevation of transaminases., (Copyright © 2012 Mosby, Inc.

Objective: To evaluate the outcome of pregnancies in women with familial Mediterranean fever (FMF) who are taking colchicine, and to reconsider the justification for amniocentesis in these women., Methods: The outcome of 179 pregnancies in a group of women with FMF taking colchicine was compared with the outcome of 197 pregnancies in women with FMF who did not take colchicine during pregnancy and with 312 pregnancies in another cohort of healthy pregnant women of similar age and ethnicity., Results: There was no difference in the 3 groups regarding early abortions, late abortions, or congenital malformations. There was a mild trend towards a better outcome for the colchicine-treated group but these results did not reach statistical significance., Conclusion: Treatment with colchicine during pregnancy in patients with FMF is beneficial in controlling the disease while not affecting the outcome of the pregnancy; therefore there is no justification for recommending amniocentesis in women taking colchicine solely because of this treatment.

Objectives: In a significant proportion of patients with familial Mediterranean fever (FMF), serum amyloid A (SAA) remains elevated during attack-free periods, thereby increasing the risk of developing amyloidosis. The aim of the study was to determine various correlates of elevated SAA and evaluate the role of SAA measurement in the diagnosis and management of FMF., Methods: We reviewed the medical files of all 204 patients from our FMF center in whom SAA measurements were performed. SAA levels and the resulting diagnostic and therapeutic decisions were analyzed in relation to the reasons of SAA testing and to several clinical and genetic parameters., Results: SAA measurements were made for diagnostic purposes in 29% of the patients. In the remainder, SAA measurements were used for adjustment of colchicine dose. Elevated SAA levels are found in a third of FMF patients during an attack-free period. The highest rate of elevated SAA levels was found in patients with proteinuria (60% of this patient group), followed by noncompliant (40%) and genetically positive asymptomatic patients (38%). Elevated SAA levels during remission were associated with family history of FMF, M694V homozygosity, and elevated C-reactive protein (CRP) (P<0.05 for each). Patients homozygous for the M694V mutation had the highest level of SAA. SAA measurement led to a change in colchicine dose in 30% of the patients, predominantly in noncompliant patients and patients with proteinuria or with atypical manifestations., Conclusions: Measurement of SAA level may help in the diagnosis of FMF and in adjustment of the colchicine dose.

Objective: To evaluate the outcome of pregnancies of normal women married to men with familial Mediterranean fever (FMF), some of whom took colchicine during the conception with their wives., Patients and Methods: We followed the outcome of pregnancies and deliveries of 60 wives of FMF patients; 53 of the husbands were taking colchicine during that time. As a control group we screened the outcome of pregnancy and delivery from 230 healthy women married to healthy men., Results: The 60 FMF patients- wives had 222 pregnancies, of which 206 ended in term delivery with 209 live births. Sixteen pregnancies ended in spontaneous abortions (7%). Three of the newborns in the study group were born with congenital malformations. In the control group, of 788 pregnancies, 127 ended in abortions (16%). Six of the newborns were born with congenital malformations. The rate of the late abortions (second trimester) in both groups was comparable., Conclusions: The results of our study indicates that neither FMF nor colchicine increases the rate of abortions or congenital malformations. Therefore we believe that there is no need to discontinue colchicine treatment in men with FMF before the conception with their wives.
