Insights

Familial Mediterranean fever (FMF) can cause chronic ascites, a rare symptom. Genetic testing and colchicine therapy are key for diagnosing and managing this FMF complication.

Area of Science:

  • Genetics
  • Internal Medicine
  • Rheumatology

Background:

  • Familial Mediterranean fever (FMF) is an autosomal recessive autoinflammatory disorder.
  • Characterized by recurrent fever and serosal inflammation, FMF typically involves mild, transient peritoneal effusion.
  • Chronic ascites is an uncommon manifestation of FMF.

Observation:

  • This study investigated four patients with unexplained chronic ascites and recurrent fevers since childhood.
  • These patients had no other identifiable cause for their ascites.
  • Genetic analysis revealed specific mutations associated with FMF in all cases.

Findings:

  • Genetic analysis confirmed Familial Mediterranean fever (FMF) in all four patients.
  • Specific genotypes included M694V homozygosity, M694V heterozygosity, and M694V/V726A compound heterozygosity.
  • Ascites resolved in all patients following colchicine treatment.

Implications:

  • Familial Mediterranean fever (FMF) should be considered in the differential diagnosis of ascites of unknown etiology, especially in endemic regions.
  • Genetic testing is crucial for accurate FMF diagnosis.
  • Colchicine therapy is effective for managing FMF-associated ascites.

Ascites

DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Pericarditis II: Clinical Features and Diagnostic Tests

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
