Treatment of cardiovascular syphilis.

The English literature on the treatment of cardiovascular syphilis with penicillin was reviewed. To date there have been no controlled randomized clinical trials to demonstrate that penicillin therapy prolongs life expectancy, alleviates symptoms, or arrests the disease process. In spite of many shortcomings in the published data, penicillin is safe and free of severe reactions. Most authors agree that significant subjective improvement in the patient's status occurs following penicillin treatment. Once the patient has become symptomatic penicillin may have little efficacy. The optimal dosage and duration of therapy have never been established. Because of its low cost, ease of administration, and lack of toxicity, it should be given to all patients with cardiovascular syphilis in hope of arresting the effects of the disease on the heart and great vessels.

Aortic Aneurysm

The erythrocyte sedimentation rate in syphilis.

The erythrocyte sedimentation rate was studied in 520 men and 202 women with syphilis. It was raised in 66-6 per cent. of sero-negative primary cases, 80 per cent. of sero-positive cases, 100 per cent. of secondary cases, 80 per cent. of early latent cases, and 73-9 per cent. of late latent cases. It was also raised in sixteen out of seventeen cases of neurosyphilis and in all eleven cases of cardiovascular syphilis. It was concluded that the ESR had little place in the management of syphilis in general, but could be helpful in the post-treatment follow-up of late syphilis.

Blood Sedimentation

Syphilis and its cardiovascular complications in the elderly.

The prevalence of syphilis and its cardiovascular complications were investigated in the living population more than 60 years of age. The prevalence of positive serologic test for syphilis (STS) were 16.9% (124/736) in males and 17.1% (236/1380) in females, which were not statistically different. Aortic regurgitation (AR) was significantly more frequent in those with positive STS (9.68% in males, 5.08% in females) compared with negative STS (0.98% in males, 1.75% in females) in both sexes (p less than 0.01) and it was marked in males. AR with positive STS had a significantly lower minimal blood pressure than AR with negative STS (p less than 0.05). Calcifications in the ascending aorta were noticed in 5 out of 24 syphilitic AR. Myocardial infarctions were almost equally found among those with positive STS (1.67%) and negative STS (1.65%), and 2 out of 6 syphilitic cases were complicated by AR. The measurement of the aortic width was not valuable for the diagnosis of uncomplicated syphilitic aortitis.

Aged

"Tree-barking" of the ascending aorta. Syphilis or systemic lupus erythematosus?

A case of unsuspected classical aortitis with "tree-barking" of the ascending aorta in a young woman with systemic lupus erythematosus and inconclusive syphilitic serologic results is presented. At autopsy, no definite diagnostic clues as to syphilitic or lupic aortitis could be obtained. Although infrequent today, the possibility of complicated cardiovascular syphilis still should be considered. Involvement of the ascending aorta by other systemic diseases is well known and can imitate syphilitic aortitis. Although the possibility of two concomitant diseases cannot be ruled out, the young age of the patient, the weak syphilitic serologic result, and active systemic lupus erythematosus demonstrated in other organs favor a diagnosis of lupic aortitis of the ascending aorta.

Adolescent

[Social importance of cardiovascular diseases].

The continual increase in such cardiovascular diseases as rheumatic and sclerotic cardiopathy and cardiovascular syphilis over the last 30 yr is noted. The social and economic effects of these diseases is stressed and the hope is expressed that more active and effective measures will be taken by the State, especially with respect to worthwhile and radical prophylaxis.

Adolescent

Treatment of late benign syphilis: review of the literature.

The English literature on the treatment of late benign syphilis with penicillin was reviewed. To date there have been no controlled randomized therapeutic trials to support the efficacy of this therapy. This disease responds rapidly to all antisyphilitic drugs including arsphenamine and heavy metals. There are ample case reports and 2 major therapy studies which demonstrate the safety and beneficial effects of penicillin in individual patients. Although the exact dosage and duration of therapy are open to speculation, it is wise to treat patients with late benign syphilis with doses of penicillin judged to be effective for concomitant neuro-or cardiovascular syphilis.

Humans

Clinical value of the Treponema pallidum haemagglutination test.

In 1,129 patients attending the Department for Sexually Transmitted Diseases, the serum was examined by three screening tests (VDRL slide, RPCF, and TPHA) and twelve cases of syphilis (1 per cent. of patients attenting the clinic) were discovered. Six of these patients were considered to have latent syphilis (5 acquired, 1 congenital) and were detected only by the TPHA; all six cases were confirmed by the FTA-ABS, The TPHA failed to detect three of the remaining six cases (2 primary and 1 very early, the latter in a contact of a patient with primary syphilis). All six cases were, however, detected by the VDRL. In seven cases, the TPHA was positive in the absence of other evidence of present or previous syphilis. In these cases the FTA-ABS was also negative. The clinical application of the TPHA test in the detection of syphilis is discussed.

Adult

Venereal syphilis in tropical Africa.

A steady decline in the incidence of positive results to the Kahn test is reported in Malawian patients during the period 1968-75. Other studies have shown that the incidence of early and late syphilis in sub-Saharan Africa has dropped considerably over the past few decades. The number of reported cases of early syphilis in certain urban areas, however, appears to be high. It is suggested that the downward trend in the incidence of syphilis in Africa is related to the increased and often indiscriminate use of penicillin.

Humans

Adverse reactions in syphilis therapy.

Reactions related to treatment of syphilis may be due to treponemal infection, therapy, or to the interaction of these. In this review I discuss the Jarisch-Herxheimer (J-H) reaction and the therapeutic paradox. Antibiotic side effects are not unique among patients treated for syphilis; therefore, readers are referred elsewhere for reviews of major antibiotic side effects. J-H reactions are acute, transient episodes with manifestations occurring both systemically and at local sites of treponemal concentration. These reactions are related to the rapid destruction of treponemes by various therapeutic agents. In this review, I suggest that J-H reactions may be significant only in syphilitic paresis, pregnancy complicated by syphilis, and when local inflammation can cause serious functional compromise, as with second or eighth cranial nerve involvement. Many workers use prednisone in conjunction with penicillin in some or all of these situations. However, the efficacy of corticosteroids has not been evaluated for such problems in clinical trials. Therefore, the use of prednisone can be supported only in very selected situations and for short duration (ie, 2 days). Therapeutic paradox, which is clinical worsening despite cure of infection, is said to result from scar formation after rapid treponemal destruction by therapeutic agents. The therapeutic paradox does not appear of great significance. Futhermore, no methods to prevent such reactions are generally advocated.

Anti-Bacterial Agents

Current status of the treatment of syphilis.

Penicillin remains the treatment of choice for syphilis, with sustained low blood levels curing virtually all patients having early syphilis and halting disease progression in most patients with symptomatic syphilis. Tetracycline, erythromycin or cephalothin yields similar cure rates for patients with early syphilis who are allergic to penicillin. The efficacy of non-penicillin regimens for the treatment of late syphilis is uncertain. Results of Venereal Disease Research Laboratory (VDRL) or other reagin tests should become negative or remain at very low titer following adequate therapy, although results of Treponema pallidum immobilization (TPI) and fluorescent treponemal antibody-absorbed (FTA-ABS) tests often remain positive.
