Insights

Acute psychosis is a rare side effect of clarithromycin in patients with acquired immunodeficiency syndrome (AIDS). Discontinuing the antibiotic resolves psychosis, indicating a direct link between clarithromycin and psychosis in AIDS patients.

Area of Science:

  • Infectious Diseases
  • Neuropsychiatry

Background:

  • Disseminated Mycobacterium avium complex (MAC) infection is a common opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS).
  • Clarithromycin is a key antibiotic used in the treatment of MAC infections.

Observation:

  • Two patients with AIDS receiving clarithromycin for disseminated MAC infection developed acute psychosis.
  • The psychosis symptoms subsided upon cessation of clarithromycin therapy.
  • Psychotic episodes reappeared when clarithromycin treatment was reinstituted.

Findings:

  • Clarithromycin can induce acute psychosis as an adverse effect in patients with AIDS.
  • The psychosis is directly attributable to clarithromycin, as evidenced by its recurrence upon re-exposure.

Implications:

  • Clinicians should consider clarithromycin-induced psychosis in AIDS patients presenting with acute psychotic symptoms.
  • Early recognition and discontinuation of clarithromycin can lead to a full recovery from psychosis.
  • This highlights the importance of monitoring for neuropsychiatric adverse events during antibiotic therapy in immunocompromised individuals.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...

Psychosis: Goals of Pharmacotherapy

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...

Mania and Antimanic Drugs: Overview

Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as a...

Myocarditis III: Medical Management

Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

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...
