To the Editor.— The suggestion of Nordin1 that there may be a need to re-evaluate the current recommended prophylaxis for children with rheumatic fever is valid, particularly if carefully planned and controlled studies could be carried out. However, the author's contention that "It has been assumed that the levels of penicillin [following monthly intramuscular injection of 1.2 million units of benzathine penicillin G] are adequate to prevent reinfection with group A streptococcus, and hence to prevent recurrences of rheumatic fever" has always been qualified by others.

Background The effectiveness of a single intramuscularbenzathine penicillin G as a secondary prevention of acute rheu-matic fever after 28 days is still controversial. The latest studyshowed that serum penicillin concentration was below protectivelevel in 4 weeks after a single intramuscular injection.Objective This study was a preliminary study to compare the in-hibiting ability of benzathine penicillin G towards group A Strepto-coccus β -hemolyticus in 21 and 28 days after a single IM injectionby using Mueller-Hinton broth method.Methods The inhibiting ability was measured by the serum in-hibitory concentration and serum bactericidal concentration aftera single intramuscular injection of benzathine penicillin G 1.2 mil-lion units.Results The subjects were 28 patients, with mean age of 15.5years (SD 3.4). The numbers of male and female were equal. Meanserum inhibitory concentration in 21 days after a single injectionwas 926.4 (SD 3080.1) and after 28 days was 1540.9 (SD 4275.1),which was not significantly different (p=0.0662). Mean serum bac-tericidal concentration in 21 days after IM injection was 1579.6(SD 4265.7) and in 28 days was 2417 (SD 6849.4) and it was notstatistically different (p=0.2276).Conclusion This study concluded that there was no significantdifference in the inhibiting ability of benzathine penicillin G to-wards group A Streptococcus β -hemolyticus between 21 and 28days after a single intramuscular injection

Local Reactions

Four types of penicillin for intramuscular injection were compared for incidence of local reaction: (1) suspension of benzathine penicillin G, 600,000 units in 1 ml; (2) benzathine penicillin G, 600,000 units, with 5 mg of prednisolone, in 1 ml; (3) benzathine penicillin G, 600,000 units, plus aqueous procaine penicillin, 600,000 units, in 2 ml; and (4) aqueous procaine penicillin, 1,200,000 units in 2 ml. A total of 320 children were evaluated at 24 hours, and the following percentages of severe local reaction were recorded for the four penicillin preparations listed: (1) 54%; (2) 9%; (3) 11.5%; and (4) 4%. The incidence of mild local reactions was the same following all four preparations, 11 to 12%. The local tolerance to benzathine penicillin G, 600,000 units, was significantly improved by combining it with either 5 mg of prednisolone, or an equal dose and volume of aqueous procaine penicillin.

Benzathine Penicillin G

Objective. To investigate the effects of 3-week versus 4-week administration of benzathine penicillin G (BPG) on the incidence of Group A streptococcal infections and the recurrences of rheumatic fever (RF). Study Design. We started, in 1979, randomly allocating all patients with RF to a 3-week or 4-week BPG prophylaxis program. They were examined at the RF clinic, every 3 to 6 months, and at any time they did not feel well. During 1979 to 1989, throat cultures and sera for antistreptolysin O and streptozyme titers were obtained at each clinic visit. Chest radiographs, electrocardiogram, color Doppler echocardiograms, and acute phase reactants were obtained. Subjects. Two hundred forty-nine patients fulfilled the revised Jones criteria and were followed until December 1991: 124 in the 3-week and 125 in the 4-week program. Their age, sex, weight, percentage with history of RF, severity of cardiac involvement, follow-up duration, and compliance to program were comparable. Eight hundred eighty throat cultures were collected in the 3-week program and 770 were collected in the 4-week program. Six hundred sixteen and 627 sera were determined in each program for antistreptolysin O, and 582 and 592 sera for streptozyme titers. Results. True streptococcal infections occurred in both programs: 39 infections in the 3-week program, and 59 infections in the 4-week program (7.5 vs 12.7 per 100 patient-years). Four infections with no antibody response occurred in the 3-week program, and three such infections in the 4-week program. Nine RF recurrences occurred in 8 patients in the 3-week program, and 16 recurrences in 16 patients in the 4-week program. Prophylaxis failure occurred in 2 of 124 patients in the 3-week program, and in 10 of 125 patients in the 4-week program (0.25 vs 1.29 per 100 patient-years). The overall recurrences/infections rate in each program was comparable, 13.6% vs 15.5%, but the recurrences/infections rate due to prophylaxis failure was higher in the 4-week program than in the 3-week program, 3.0% versus 9.7%. Conclusions. This 12-year prospective and controlled study documented that streptococcal infections and RF recurrences occurred more often in the 4-week program than in the 3-week program. The risk of prophylaxis failure was fivefold greater in the 4-week program than in the 3-week program.

Table I summarizes most of the pertinent data in this report on the serum penicillin concentrations 12 and 24 hours after intramuscular injection of K penicillin G in peanut oil and beeswax, which is fluid at room temperature, and of three different procaine penicillin preparations. These three preparations are procaine penicillin G in sesame oil, procaine penicillin G in peanut oil with 2% aluminum monostearate, and procaine penicillin G in water with Na-carboxymethylcellulose. When they were given in a dosage of 8000 u./lb. to infants and children, weighing between 4.5 and 18.0 kg., there was no statistically significant difference in the serum levels obtained. A dosage schedule for these preparations is suggested for pediatric use. The aqueous preparation offers some advantages which are discussed. Experiences are reported which emphasize the necessity of avoiding intravenous administration of all these preparations.

Benzathine Penicillin G

The definition, pathogenesis, incidence, diagnosis, and treatment of neurosyphilis are discussed. Controlled trials of benzathine penicillin in the treatment of neurosyphilis are reviewed, as are recent case reports of benzathine penicillin failures. Although few well-controlled studies exist to document conclusively the efficacy of benzathine penicillin in the treatment of neurosyphilis, its use is recommended in selected situations.
