Abstract
Symptoms of syphilis have evolved over the ages. In the 16th century, they were essentially cutaneomucous ones. While the intensity of the symptoms decreased localization of the infection in the various organs--mainly those of the cardiovascular and nervous system--gradually appeared. Over a period of years following the introduction of penicillin therapy, the cutaneous and visceral stages became less common. Reminder of the chief serological reactions and of some aspects of the experimental syphilis in the rabbit, similar to certain forms of human syphilis--a strong but late penicillin therapy has been proven ineffective in humans as well as in animals. It is to be regretted that numerous methods of using penicillin (all over the world), had been, from the beginning--except in a few cases--of a purely empirical nature. The authors emphasize--with proof to support their opinion--the failure of antibiotic therapy, which can explain the recent reappearance of hepatic and nervous localizations that had disappeared for 30 years. Despite views to the contrary the authors conclude that penicillin has in no way resolved all the problems raised by the treatment of syphilis.

Abstract
A streptococcus, AW 43 strain, was found to bind nonspecific serum inhibitors of rubella virus hemagglutination (HA). This was demonstrated by titration of nonspecific HA inhibitors and by immunoelectrophoresis. Absorption of sera with the mixture of AW 43 cells, which bind IgA in addition to nonspecific HA inhibitors, and AR 1 cells, another strain of streptococci which bind IgG, removed nonspecific HA inhibitors, IgG, and IgA simultaneously, leaving behind IgM and a trace of IgA. Pretreatment of sera with those streptococcal cells prior to the rubella hemagglutination inhibition (HI) test enabled to circumvent kaolin treatment of sera, which partially removes IgM antibodies, and to determine exclusively the early-appearing antibodies. The rise and fall of the HI antibodies thus determined correlated well with that of the IgM antibodies determined by enzyme-linked immunosorbent assay (ELISA). Thus, this modified rubella HI test may be useful for serodiagnosis of recent rubella virus infection.

Abstract
Forty-four living-related donor kidney (LRD) recipients (19 HLA-identical and 25 haploidentical) were followed prospectively to determine the posttransplant incidence and sequelae of cytomegalovirus (CMV) infection as they relate to the CMV status of recipients and donors. CMV titers were measured in all patients before transplantation by an immunofluorescent assay (IFA). Recipients similarly had CMV titers measured at selected intervals after transplant and during febrile episodes. Appropriate viral cultures were simultaneously performed. Laboratory evidence of infection was correlated with symptoms and signs of active CMV disease. Mean follow-up period was 20 +/- 12 months with a range of 3-51 months. Three patients were excluded due to early acute rejection resulting in graft loss. Twenty-eight of 41 donors (68%) and 22 of 41 recipients (54%) had positive CMV titers before transplantation. Six of 41 recipients (15%) subsequently developed clinical and laboratory evidence of CMV infection: three of 19 seronegative recipients and three of 22 seropositive recipients. All six patients received kidneys from seropositive donors. Four patients had severe CMV disease (2 seronegative, 2 seropositive), whereas two patients had leukopenia and fever only. Two patients with severe CMV infections subsequently lost their grafts due to unrelated causes. Overall, actual patient and graft survival of the entire group is 95% and 82%, respectively. In conclusion, individuals who receive LRD kidneys from seronegative individuals are unlikely to develop CMV infection, and transplantation of seropositive LRD kidneys may be associated with transmission of CMV in susceptible recipients regardless of their serologic status. With appropriate management of CMV illness in the posttransplant period, LRD kidney donation is safe and efficacious and should not be discouraged on the basis of pretransplant CMV serology in any donor-recipient pairing.

Abstract
The cross-reactivity of the blood from onchocerciasis, loiasis, and dipetalonemiasis was tested by a micro-ELISA technique, utilizing adult Onchocerca volvulus antigen and blood samples taken on filter paper. The average ELISA values (OD at 500 nm) were as follows: 0.58 in persons with O. volvulus microfilariae (n = 81), 0.49 in microfilariae-negatives from the same endemic area (n = 39), 0.15 in dipetalonemiasis (n = 27), and 0.25 in loiasis (n = 12), while those of 65 Dipetalonema perstans-negative people were markedly low (average 0.14) and that of 22 Loa loa-negatives, 0.22, respectively. This ELISA could successfully differentiate onchocerciasis from dipetalonemiasis and loiasis.

Abstract
Cloned Leishmania donovani chagasi (Ldc) promastigotes were analyzed by SDS-PAGE separation and immunoblotting with human infection sera. The patterns of antigen reactivity were compared by using sera from individuals with Ldc, Leishmania mexicana amazonensis (Lma), Trypanosoma cruzi, Mycobacterium tuberculosis, or Mycobacterium leprae infections. Sera from individuals with these infections recognized Ldc antigens in several m.w. ranges. Reactivity was due to recognition of Ldc molecules and not to Ldc culture medium components, as shown by comparing Ldc promastigotes grown in the presence or absence of fetal bovine serum (FBS), by immunoblotting of FBS, and by [35S]methionine labeling. The major findings of the study were as follows. Immunoblots with Ldc promastigotes could be used to distinguish individuals with Ldc infections from those with Lma infections. Persons with Ldc infections had antibodies to a Ldc antigen of approximately 32 to 35 kd not recognized by persons with Lma infections. Individuals cured of acute Ldc infection did not develop antibodies that differed in specificity to those present during their acute phase of infection. Ldc antigens in the 62 to 66 kd region were recognized by all individuals with Ldc or Lma infections but were not recognized by individuals in the other disease groups or by control sera. This region was found to contain at least four distinct bands, one of which appeared to be glycosylated as indicated by periodic acid-Schiff staining and concanavalin A labeling; an apparently nonglycosylated protein of 62 to 63 kd was eluted from SDS-PAGE gels and was used to diagnose Ldc infection by the ELISA. Whereas crude Ldc antigen gave false positive results with T. cruzi and mycobacteria infection sera, the eluted 62 to 63 kd protein was 100% specific and sensitive in the diagnosis of Ldc infection.

Abstract
Fifty-six patients with moderate to severe neonatal hepatitis were followed for 12 to 78 months. Two died from causes other than hepatitis itself and were free from liver disease at the time of death. Of the remaining 54 patients, seven died of hepatitis, two are living with chronic liver disease and psychomotor retardation, and 45 are living without liver disease. High peak bilirubin levels and liver histologic findings of periportal fibrosis, moderate to severe portal inflammation, and/or diffuse giant cell transformation appear to be major factors predictive for poor outcome. Cytomegalovirus (CMV) infection was a common associated infection. Evidence of CMV infection was found in 22 (49%) of the 45 patients studied. Three of them died, and one is still living with cirrhosis of the liver. Metabolic disorders such as alpha-1-antitrypsin deficiency, galactosemia, and aminoaciduria and/or aminoacidemia were carefully screened but were not found in these cases. A fatal case had a sibling who had died of a similar disease course. Chinese infants may have metabolic and familial cholestasis diseases requiring further investigation.

Abstract
Sera from 123 patients with confirmed tuberculosis and 576 patients with other non-mycobacterial diseases were tested for antibodies to an adsorbed mycobacterial sonicate antigen employing an enzyme-linked immunosorbent assay. The results show significant differences in IgG levels between sera from tuberculosis patients and controls. The results of delayed hypersensitivity skin-test reactions to purified protein derivative in both the patient and control groups were unrelated to antibody levels. The assay was able to detect antibodies for at least 4 months after diagnosis and treatment. Patients diagnosed as having tuberculosis 7 months or more before being tested did not demonstrate increased antibody levels. The assay could be useful not only as a screening technique for diagnosing tuberculosis in an immunised population but also as a means of monitoring antituberculosis treatment.

Abstract
We describe a method for the serodiagnosis of Streptococcus faecalis in infective endocarditis which could be of value in culture-negative cases. Serum-grown cells of S. faecalis produced three major characteristic protein antigens (73,000, 40,000, and 37,000 molecular weight) which were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis of solubilized whole cells. After electrophoretic transfer to a nitrocellulose membrane, these antigens were visualized by probing with serum from patients with endocarditis caused by S. faecalis. Serum from patients with endocarditis caused by other organisms did not react with the S. faecalis-specific antigens. This procedure should facilitate positive early diagnosis of S. faecalis endocarditis or establish its absence in culture-negative cases.

Abstract
Infection by spirochete Borrelia burgdorferi is mainly observed in the United States where it has taken the name of Lyme's disease, and in Europe. Its evolution may be very extended, in several phases. A few weeks after a tick-bite, the primary lesion appears, which is a chronic migrating erythema. In the following weeks or months, in the secondary phase, nerve lesions may appear, quite similar in Europe and in the United States, and cardiac lesions, mostly seen in the United States. In the following weeks, months, or years, during the tertiary phase, articular lesions may appear, frequent in the United States, much more unusual in Europe. Several years later, chronic lesions of the central nervous system may appear, described in the United States, and chronic skin lesions such as chronic atrophying acrodermatitis sometimes associated with destructive lesions of the joints underlying the skin lesion, which are only recognized in Europe. The discovery of the spirochete in a small number of these lesions, including the latest in the evolution, permits to think that, throughout this evolution, this disease is secondary to the persistence of the germ within the body; this explains the efficacy of the penicillin treatment, including in the oldest forms of the disease. Serology is quite reliable; but it becomes positive only 2 to 4 weeks after the onset of the chronic migrating erythema: needless to say the importance of this single cutaneous lesion which enables to make the diagnosis and requires the use of a tetracycline or penicillin treatment.

Abstract
The San Francisco Men's Health Study is a prospective study of the epidemiology and natural history of the acquired immunodeficiency syndrome in a cohort of 1034 single men, 25 to 54 years of age, recruited by multistage probability sampling. At entry, June 1984 through January 1985, the seropositivity rate for human immunodeficiency virus (HIV) infection among homosexual/bisexual study participants was 48.5%. No heterosexual participants were HIV seropositive. Among homosexual/bisexual men reporting no male sexual partners in the two years before entry into the study, seropositivity was 17.6%. For those reporting more than 50 partners, seropositivity was 70.8%. Only receptive anal/genital contact had a significantly elevated risk of HIV infection. Douching was the only ancillary sexual practice that contributed significantly to risk of infection.

Abstract
Oviductal damage from infectious salpingitis is a principle cause of ectopic pregnancy. To examine the role of Chlamydia trachomatis in patients with ectopic pregnancy, 24 patients undergoing laparotomy for ectopic pregnancy were evaluated by assessment of chlamydial serology and chlamydial cultures of tubal biopsy specimens. The patients were divided into two groups based on the presence or absence of gross abnormalities in the fallopian tube contralateral to the ectopic gestation. Ten patients in group I showed gross evidence of chronic salpingitis in the contralateral tube; 14 patients in group II had normal-appearing contralateral tubes. Chlamydial cultures were negative in both groups. Chlamydial immunoglobulin M antibodies assayed by indirect microimmunofluorescence were negative in both groups (less than or equal to 1:32). Mean geometric immunoglobulin G titers for C. trachomatis were significantly higher in the patients with evidence of contralateral chronic salpingitis (78.9 versus 13.1). These findings suggest that C. trachomatis may be a major cause of oviductal damage, which predisposes to ectopic pregnancy.

Abstract
Five patients with chronic meningitis were hospitalized several times for progressive neurological symptoms. The clinical manifestations included cranial neuritis, radiculoneuritis, myelitis and encephalitis. In two cases cerebral infarction occurred. The course was commonly characterized by a tendency to deteriorate. From the clinical point of view, it was repeatedly difficult to exclude multiple sclerosis or tuberculous meningitis. Finally, specific antibodies against Borrelia burgdorferi were detected by indirect immunofluorescence assay. The diagnosis of a borreliosis was not considered initially because there was no history of tick-bite or erythema chronicum migrans, and the neurological involvement of the central nervous system seemed unusual. The latency between the first symptoms and diagnosis varied from 3 months to 5 years. After a parenteral, high-dose therapy with penicillin, there was a significant improvement in all patients. In two cases, there was evidence of intrathecally produced antibodies to myelin basic protein.

Abstract
To determine whether HTLV-III/LAV is transmitted to men by heterosexual contact and whether contact with prostitutes plays a role in such transmission, a serosurvey was conducted in clinics for sexually transmitted diseases in New York City. Two hundred ninety-five male heterosexual nonusers of intravenous drugs were studied. Antibody to HTLV-III/LAV was found in sera from ten men (3.4%); this rate is approximately 15 times the prevalence found in healthy blood donors. Seropositivity was associated with serologic evidence of syphilis (odds ratio, 11.2; 95% confidence interval, 2.1-52) and hepatitis B infection (odds ratio, 9.1; 95% confidence interval, 2.0-55). Antibody to HTLV-III/LAV was not associated with self-reported exposure to prostitutes (odds ratio, 0.8; 95% confidence interval, 0.08-4.2). These findings suggest heterosexual transmission of HTLV-III/LAV to men but fail to implicate contact with prostitutes as a mode of such transmission.

Abstract
The ability of the Streptozyme test to identify significant antibody rises in 46 patients with streptococcal pharyngitis was comparable to, but no greater than, that of the antistreptolysin O or antideoxyribonuclease B test and inferior to that of the combined use of both the antistreptolysin O and antideoxyribonuclease B tests. Serum specimens were also simultaneously analyzed with three different lots of Streptozyme reagent. Lot-to-lot variation in the reagent resulted in a significant difference in antibody titer for 18 (19%) of the 92 sera tested. Differences among the three lots also produced variation in determining whether a significant rise in titer had occurred from the acute phase to the convalescent phase serum for a given patient. These observations raise concerns about the standardization of the Streptozyme reagent and document the need for precise identification and quantitation of the streptococcal antigens used in this product.
