[The efficacy of using chymotrypsin in the combined treatment of syphilis patients].

Clinical, serologic, and immunologic studies carried out before and after treatment in 102 patients treated with benzylpenicillin according to the scheme developed at the Kuibyshev Medical Institute and chymotrypsin and in 55 patients treated with penicillin alone evidence the efficacy of chymotrypsin. The drug favorably influenced the terms of syphilid regress, negative answers were sooner obtained in classical serologic tests, and the time course of cellular immunologic tests was more favorable.

Treponema pallidum in leukoderma syphiliticum demonstrated by electron microscopy.

Punch biopsies from syphilitic leukoderma lesions and from unaffected skin in 3 patients with secondary syphilis were studies in the transmission electron microscope. In one of the patients the pigment disorder was not preceded by any visible syphilids, and in the biopsy from the leukodermal skin in this patient Treponemata pallidium were demonstrated around vessels and inside nerve fibres in which the myelin sheaths of the axons showed evidence of degeneration. In the other 2 patients the depigmented areas appeared while macular and papular syphilitic lesions were healing. In the biopsies from the leukodermal lesions of these 2 patients and from unaffected skin of all 3 patients, no treponemes were demonstrated. The study indicates that syphilitic leukoderma is not invariably a post-inflammatory phenomenon, but the pigmented skin lesions may themselves represent stigmata of an active syphilitic infection.

[Liver involvement in syphilis].

The authors report two cases of syphilitic hepatitis. In the first case, acute hepatitis occurred during the secondary stage of syphilis. The diagnosis was made without waiting for the hepatitis to respond to penicillin treatment, on the basis of the following signs: icterus involving inflammatory syndrome, moderate cytolysis, clear retention, eruption of papular syphilids and a strongly positive test for syphilis. The second case involved a female patient who had been treated 15 years earlier for bone syphilis with ulcerous gummas. The signs were sclerotic, gummatous, hepatic lesions revealed by a syndrome of calcified hepatic lesions. The serologic test for syphilis was negative in this patient. Laparotomy and biopsy were necessary before a firm diagnosis could be made. The authors examine literature data concerning this pathology.

Morphology of Treponema pallidum.

In recent years many investigations have been carried out on the morphology of Treponema pallidum by means of the electron microscope, and the use of ultra-thin sections has shown up a number of structural details. However, there is still need for much more evidence before the internal structure of treponemes can be elucidated fully and the functions of the structures interpreted. To provide such evidence, the authors have examined under the electron microscope negative-stained treponemes and ultra-thin sections, using both cultivated strains and treponemes obtained direct from syphilids in people suffering from fresh secondary syphilis. It has been shown that treponemes have a complex structure. T. pallidum has a two-layered outer wall, a cytoplasmic membrane proper, cytoplasm and a bunch of fibrils following a different path in different places on the treponeme. The sites of insertion of the fibrils (the basal granules) were investigated; structures similar to mesosomes and nucleoids were found. Cysts and granular forms are described.

Secondary syphilis. Clinical morphology and histopathology.

Twenty-four biopsy specimens of skin were taken from 23 patients with several types of lesions of secondary syphilis. In macular and maculopapular lesions, the histological changes were not specific. No or few plasma cells were observed in specimens at this stage. In early papular lesions, the histological appearance was more diagnostic. A lymphohistiocytic bandlike infiltrate was present in the upper part of the dermis and extended around blood vessels of the deep plexus. In nearly two-thirds of the cases, plasma cells were present in early papular lesions. The epidermis, too, was frequently involved in these lesions of the disease. In late papular lesions, the pathologic features were distinctive. The infiltrate was dense, diffuse, and, in some instances, nearly completely plasmocytic. In nummular syphilides, many neutrophils were present in a hyperplastic epidermis, whereas in corymbiform lesions, the epidermis was not involved at all.

Papulonecrotic tuberculid. A clinical, histopathological, and immunohistochemical study of 15 patients.

We report 10 women and five men with papulonecrotic tuberculid, an uncommon form of cutaneous tuberculosis (TB). The mean age was 22.6 years (range, 2 1/2-35 years) at presentation. The Mantoux test was strongly positive in 13 patients. Five patients showed presumptive evidence of associated TB; in one case, the presence of TB was proven by culture. Response to anti-TB was dramatic in all cases. Clinical findings were similar to those previously published. We emphasize the simultaneous occurrence of erythema induratum, associated Takayasu's disease, possible associated phlebitic tuberculid, and clinical mimicry of acute bacterial endocarditis. The main histopathological findings obtained from 27 biopsy specimens included dermal necrosis (26 of 27 cases), a poorly formed granulomatous infiltrate (27 of 27 cases), vasculitis (11 of 27 cases), perivascular spongy edema (11 of 27 cases), and follicular necrosis or suppuration (five of 27 cases). A Ziehl-Neelsen stain was negative in all biopsy specimens. Immunohistochemical labeling revealed a preponderance of T-lymphocytes (UCHL-1+), monocytes-macrophages (S-100+), and Langerhans cells (ACT+), indicative of a type IV hypersensitivity reaction. B-lymphocytes (L26+) were sparse. Conditions that may be confused with PNT on clinical or histopathological ground include pityriasis lichenoides et varioliformis acuta, papular urticaria, papulopustular syphilide, miliary TB, septicemia, perforating granuloma annulare, chondrodermatitis nodularis, reactive perforating collagenosis, allergic granulomatosis, suppurative folliculitis, and infectious causes of palisading granulomas. Papulonecrotic tuberculid has distinct clinical, histopathological, and immunohistochemical features. Awareness of this entity is important since an appropriate diagnosis is necessary for the institution of timely curative treatment.

[Azithromycin in the treatment of syphilis].

The results of the use of azithromycin (sumamed) in the treatment of 100 patients with fresh syphilis were analyzed. The antibiotic was used in accordance with two treatment schemes: 500 mg daily for 10 days and 500 mg every two days. The total course dose was 5 g in both the cases. The results of the treatment with azithromycin were compared with those of the treatment with erythromycin (30 g) and penicillin (300,000 U every 3 hours for 16-28 days depending on the disease stage). The results were estimated by the rate of the elimination of Treponema pallidum and syphilids as well as by the time course of the seroreactions. The analysis provided a conclusion that the therapeutic efficacy of sumamed in the treatment of patients with fresh manifest syphilis was high: by comparison with penicillin and erythromycin it more rapidly eliminated the clinical signs of syphilis and in the majority of the cases induced negativation of the cutaneous serological reactions within the first 4 months of the treatment.

[The Extencillin treatment of patients with early forms of syphilis].

Outpatient treatment of syphilis was given to 250 patients. All of them received extencilline (benzathine penicillin G) in intramuscular injections. One injection of the drug (2400000 U) was administered for primary seronegative syphilis (15 cases) and for prevention (65 subjects). Two injections with 7-day interval were carried out in the dose 2400000 U for primary seropositive (58 cases), secondary early (14 cases) and recurrent syphilis (36 cases). Patients with secondary recurrent syphilis whose body mass exceeded 85 kg (55 cases) and subjects with latent disease (72 cases) received 3 injections in 7-day intervals. Extencilline proved a potent antisyphilis tool able to rapidly eliminate clinical symptoms of the disease and to promote making serological reactions negative. Extencilline activity is superior to that of bicillin and water-soluble penicillin. Treponema pallidum escape from syphilid surface within 7 treatment hours, on the average. Extencilline is worthy of being used among most effective drugs in outpatient treatment of early syphilis.

[The combination of secondary recurrent syphilis and HIV infection].

HIV infection in connection with other venereal diseases change greatly there clinic development. Authors discuss comprehensively the peculiarities of infectious process in case of syphilis connection with HIV-infection, and in particular face syphilid, which is met little in practice of venereologists. Syndrome of aggravating influence of HIV-infection on clinic syphilis development is noted. It usually more serious. In given example syphilis was diagnosed only two month later after patient had took medical advice.
