Abstract:
Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent inflammatory febrile attacks, abdominal, chest or joint pain, myalgia, and erysipelas-like skin lesions. Several types of vasculitis are associated with FMF such as polyarteritis nodosa and Henoch-Schönlein purpura. We aimed to determine microvascular abnormalities in FMF patients via nailfold capillaroscopy using a dermoscope. Thirty-one FMF patients were assessed; capillary enlargement, tortuosity, avascular areas and microhemmoraghes were investigated. Capillary enlargement was found in five patients and microhemorrhages in one patient. Our study supports that nailfold capillary abnormalities, which are nonspecific, can be seen in FMF patients, but more studies are needed to clarify the importance of these findings.
Insights
Familial Mediterranean fever (FMF) patients may show nailfold capillary abnormalities. These nonspecific findings, including capillary enlargement and microhemorrhages, warrant further investigation to understand their significance in FMF.
Area of Science:
- Rheumatology
- Genetics
- Dermatology
Background:
- Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease.
- FMF presents with recurrent febrile attacks and symptoms like abdominal pain, joint pain, and skin lesions.
- Associated vasculitic conditions include polyarteritis nodosa and Henoch-Schönlein purpura.
Purpose of the Study:
- To investigate microvascular abnormalities in FMF patients.
- To utilize nailfold capillaroscopy with dermoscopy for detailed microvascular assessment.
Main Methods:
- Nailfold capillaroscopy was performed on thirty-one FMF patients.
- Assessment focused on capillary enlargement, tortuosity, avascular areas, and microhemorrhages.
Main Results:
- Capillary enlargement was observed in five FMF patients.
- Microhemorrhages were noted in one FMF patient.
- The observed nailfold capillary abnormalities were nonspecific.
Conclusions:
- Nonspecific nailfold capillary abnormalities can be present in patients with Familial Mediterranean fever.
- Further research is required to elucidate the clinical significance of these microvascular findings in FMF.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
