Summary
Ivermectin effectively treats Loiasis, a parasitic infection common in Africa. However, a rare case shows it can cause severe liver disease, highlighting the need for careful monitoring.
Area of Science:
- Tropical medicine
- Hepatology
- Parasitology
Background:
- Loiasis, caused by the filarial parasite *Loa loa*, is prevalent in West and Central Africa.
- Ivermectin is a recognized and effective treatment for loiasis.
- Drug-induced liver injury (DILI) is a significant concern in pharmacotherapy.
Observation:
- A 20-year-old woman from Cameroon with loiasis received a single dose of ivermectin.
- One month post-treatment, she developed severe hepatitis.
- Liver biopsy revealed inflammatory infiltrates and necrosis, indicative of drug-induced liver disease.
Findings:
- This case represents the first documented instance of severe liver disease potentially induced by ivermectin in a loiasis patient.
- Histopathological findings were consistent with drug-induced liver injury.
- The temporal association suggests a possible link between ivermectin and the observed hepatitis.
Implications:
- Clinicians should be vigilant for potential hepatotoxicity when prescribing ivermectin for loiasis, especially in endemic regions.
- Further research is warranted to elucidate the mechanisms and incidence of ivermectin-induced liver injury.
- This finding underscores the importance of post-treatment monitoring for adverse drug reactions in tropical diseases.

01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
01:26Rocky 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.
01:08Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...
01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...
