Summary
Familial Mediterranean fever (FMF) is an inherited autoinflammatory disorder. Early diagnosis and treatment with colchicine, especially for the p.Met694Val mutation, can prevent severe complications like renal failure.
Area of Science:
- Genetics
- Immunology
- Internal Medicine
Background:
- Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disease.
- Two phenotypes exist: Type 1 involves recurrent inflammatory episodes, while Type 2 presents initially with amyloidosis.
- Amyloidosis, a severe complication, can lead to renal failure.
Purpose of the Study:
- To summarize the clinical characteristics and management of Familial Mediterranean fever.
- To highlight the importance of genetic testing and early intervention.
Main Methods:
- Review of existing literature on Familial Mediterranean fever.
- Analysis of clinical phenotypes and genetic mutations, particularly p.Met694Val in the MEFV gene.
Main Results:
- FMF presents with variable inflammatory symptoms (serositis) or as initial amyloidosis.
- Lifelong colchicine treatment is crucial for individuals with the p.Met694Val mutation to prevent inflammation and amyloid deposition.
- Molecular genetic testing of the MEFV gene aids in early diagnosis and prevention of complications.
Conclusions:
- Prompt diagnosis and treatment of FMF, guided by genetic testing, are essential for preventing severe outcomes like renal failure.
- Colchicine therapy is highly effective in managing FMF and preventing amyloidosis, especially in individuals with specific MEFV mutations.
- Monitoring for proteinuria is recommended for mildly affected individuals without the p.Met694Val mutation.

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...

01:18Yellow Fever
Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...
01:22Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...
