Summary
Mefloquine, used for malaria, can rarely cause eosinophilic pneumonia. This case report highlights a potential severe adverse effect of the antimalarial drug, mefloquine.
Area of Science:
- Pulmonology
- Pharmacology
- Infectious Diseases
Background:
- Mefloquine is a common antimalarial drug for prophylaxis and treatment.
- While generally well-tolerated, mefloquine can cause rare severe adverse effects.
- These adverse effects can impact various organ systems, including the gastrointestinal, neuropsychiatric, cardiovascular, and musculoskeletal systems.
Observation:
- A 67-year-old woman presented with fever, exertional dyspnea, and pulmonary infiltrates.
- Peripheral blood eosinophilia was noted on laboratory examination.
- The patient had been taking mefloquine for malaria prophylaxis during an 8-week trip.
Findings:
- A diagnosis of eosinophilic pneumonia was established.
- The condition was attributed to mefloquine use.
- Pulmonary symptoms resolved after discontinuation of the drug.
Implications:
- This is the first reported case of mefloquine-induced eosinophilic pneumonia.
- Clinicians should consider eosinophilic pneumonia in patients presenting with respiratory symptoms after mefloquine use.
- Awareness of this rare adverse effect is crucial for patient safety and effective malaria treatment.

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.
Malaria
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...
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...
Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Inhibitors of Bacterial DNA Synthesis
Bacterial pathogens depend on precise and efficient DNA replication to sustain infection. Two type II topoisomerases—DNA gyrase and topoisomerase IV—are critical to this process, as they resolve DNA supercoiling and unlink chromosomes during replication. Fluoroquinolones, synthetic derivatives of quinolones, exploit this mechanism by stabilizing the transient DNA–enzyme cleavage complex, preventing strand religation, and causing lethal double-strand breaks. These antibiotics are selectively...
Antiepileptic Drugs: Potassium Channel Activators
Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.
