Background/aim: Colchicine is the mainstay of treatment in FMF. However, in daily practice it is not easy to maintain effective colchicine doses in a substantial number of patients due to its side effects. In this study, we aimed to investigate prevalence and risk factors for colchicine side effects that limit optimal drug dosing and cause permanent discontinuation.
Materials And Methods: All patients were recruited from “FMF in Central Anatolia” (FiCA) cohort, 915 adults with a minimum follow- up time of 6 months during which they had obeyed all treatment instructions. Demographic and anthropometric data, FMF disease characteristics, disease severity, complications, and treatment features were recorded on a web-based registry. Prevalence of colchicine intolerance and characteristics of intolerant patients were analyzed.
Results: Effective colchicine doses cannot be maintained in 172 (18.7%) subjects. Main side effects that limit optimal dosing were as follows: diarrhea in 99 (10.8%), elevation in transaminases in 54 (5.9%), leukopenia in 10 (%1.1), renal impairment in 14 (1.3%), myopathy in five (0.5%), and allergic skin reaction in two. Colchicine had to be permanently ceased in 18 (2%) patients because of serious toxicity. Male sex and obesity were found to be associated with liver toxicity, and having a normal body weight was associated with diarrhea. Chronic inflammation and proteinuria were more common in colchicine-intolerant patients, and they had reported more frequent attacks compared to those tolerating optimal doses.
Conclusion: Colchicine intolerance is an important problem in daily clinical practice, mainly due to diarrhea and liver toxicity. Suboptimal colchicine dosing is associated with complications.

Background: Women are underrepresented in drug development trials and there is no sex-tailored drug regimen for most medications. It has been repeatedly shown that women have more adverse drug reactions than men for several medications. These differences could be explained by higher dose-adjusted drug concentrations in women.

: Familial Mediterranean fever (FMF) is an inherited autoinflammatory disease characterized by recurrent febrile attacks and serosal inflammation. The goals of FMF treatment are to prevent acute attacks and the development of amyloidosis. This study aimed to investigate the benefit of switching to compressed colchicine tablets in patients with FMF who are resistant or intolerant to the pharmaceutical preparation of coated colchicine tablets in terms of attack frequency and side effects.

Familial Mediterranean Fever (FMF) is the most common hereditary autoinflammatory disease, characterized by recurrent fever, arthritis, rash, and serositis, and is caused by mutations in the MEFV gene coding for the pyrin protein. The primary treatment goal is to prevent acute attacks and minimize subclinical inflammation to avoid secondary amyloidosis with colchicine as the first-line treatment. However, 10-20% of patients are colchicine-resistant or intolerant.

Imatinib (IM), a breakthrough in chronic myeloid leukemia (CML) treatment, is accompanied by discontinuation challenges owing to drug intolerance. Although mutation is a key cause of CML resistance, understanding mechanisms independent of is also important. This study investigated the sphingosine-1-phosphate (S1P) signaling-associated genes ( and ) and their role in BCR-ABL1-independent resistant CML, an area currently lacking investigation.
