Low dose penicillin for gonococcal arthritis. A comparative therapy trial

Area of Science:

• Infectious Diseases
• Rheumatology
• Pharmacology

Background:

• Gonococcal arthritis, a disseminated infection caused by Neisseria gonorrhoeae, can lead to joint damage if untreated.
• Penicillin has historically been the primary treatment, but optimal dosing for gonococcal arthritis remains a subject of investigation.

Purpose of the Study:

• To compare the efficacy of a low-dose intramuscular procaine penicillin regimen with a high-dose regimen including intravenous aqueous penicillin for treating gonococcal arthritis.

Main Methods:

• A double-blind, randomized trial involving 63 patients with gonococcal arthritis.
• Patients received either low-dose procaine penicillin (600,000 units IM q12h for up to 10 days) or high-dose therapy (same IM regimen plus 10 million units IV aqueous penicillin daily for 3 days).
• Outcomes were assessed based on therapeutic response variables.

Main Results:

• All patients in both groups showed definite improvement within 48 hours.
• No significant differences in therapeutic response were observed between the low-dose and high-dose penicillin groups.
• No complications or treatment failures occurred in either group.

Conclusions:

• Low-dose intramuscular procaine penicillin is an effective treatment for gonococcal arthritis.
• High-dose penicillin, including intravenous administration, does not offer additional therapeutic benefit.
• Standard low-dose intramuscular penicillin therapy is sufficient and avoids unnecessary intensive treatment.
