Clinical problems in the antibiotic treatment of gonorrhoea
Abstract:
After briefly reviewing the history of penicillin therapy in gonorrhoea, the author shows that the number of cures effected with the repository penicillins, although originally very high, has diminished considerably in recent years, despite a general tendency to increase the dosage. The reduced efficacy of PAM and benzathine penicillin is demonstrated by an exposition of the current results obtained with these two preparations in the treatment of gonorrhoea patients in London. Some of the difficulties involved in distinguishing between treatment failures and reinfections are discussed.The paper continues with an examination of the possible alternatives to repository penicillin in the treatment of gonorrhoea. Data are given on the comparative efficacy of a number of prepations, including mixed penicillins, phenoxymethyl penicillin and various other antibiotics, such as streptomycin and the tetracycline group.The problem of re-examination of treated gonorrhoea cases is also dealt with, practical reasons being given for restricting the period of follow-up to three weeks.Finally, in a discussion of possible future developments, the author suggests a number of measures designed to prevent a further loss of sensitivity to penicillin in the gonococcus.
Insights
Repository penicillin efficacy for gonorrhea has declined, necessitating exploration of alternative antibiotics like streptomycin and tetracyclines. Further research is crucial to combat rising penicillin resistance in Neisseria gonorrhoeae.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Penicillin therapy historically demonstrated high cure rates for gonorrhea.
- Recent years show a diminishing efficacy of repository penicillins (e.g., PAM, benzathine penicillin) despite increased dosages.
- Distinguishing treatment failures from reinfections presents diagnostic challenges.
Purpose of the Study:
- To review the historical efficacy of penicillin in treating gonorrhea.
- To evaluate the current reduced effectiveness of repository penicillins (PAM and benzathine penicillin).
- To explore and compare alternative antibiotic treatments for gonorrhea.
Main Methods:
- Review of historical data on penicillin therapy for gonorrhea.
- Analysis of current treatment outcomes for PAM and benzathine penicillin in London gonorrhea patients.
- Comparative efficacy assessment of alternative treatments including mixed penicillins, phenoxymethyl penicillin, streptomycin, and tetracyclines.
- Discussion on the re-examination of treated gonorrhea cases and follow-up periods.
Main Results:
- Repository penicillins show diminished cure rates in recent years.
- Reduced efficacy observed with PAM and benzathine penicillin in current London studies.
- Comparative data suggests varying efficacy among alternative antibiotics.
Conclusions:
- The declining efficacy of repository penicillins necessitates the consideration of alternative treatments for gonorrhea.
- Further investigation into antibiotics like streptomycin and tetracyclines is warranted.
- Strategies to prevent further loss of gonococcal sensitivity to penicillin are essential for future treatment success.
