Was this reply helpful? Yes No. To correct this lack of data, we conducted a serologic study using serum specimens collected from red deer in different regions in France. Blood samples from red deer, which had been either killed by gunshot or captured, were collected within 9 French departments administrative units during 1 or 2 sampling seasons i.
A subset of samples were also subjected to a seroneutralization test SNT as described 7. Breard, pers. Considering the performance of serologic methods in that study, seroprevalence was finally estimated as the proportion of positive or doubtful serum specimens by using the c-ELISA kit. The number of samples collected in each department, the proportion of positive specimens, and the date of first observation of seropositive result are indicated in Table 2.
It is thus likely that SBV had not spread to France before red deer in France gave birth to young in spring mid-May to early June 8. These results suggest that SBV was actively circulating during fall until mid-November or early December. In agreement with the findings of Linden et al. The date of first occurrence of seropositive red deer and the seroprevalence observed in each department Table 2 were not strictly dependent on the distance from the Meurthe-et-Moselle department where the first domestic case congenital form had been confirmed on January 25, 10 Figure.
This result possibly arose because of uncontrolled variations in the sampling dates of red deer between the 9 departments and still unknown factors associated with SBV spread. Nevertheless, most of the departments that exhibited seropositive red deer from September to March had also reported clinical cases in domestic flocks during January—March Figure.
Sites where serum samples were obtained from red deer 9 departments , showing average seroprevalence for Schmallenberg virus, France, — Dark gray shading indicates Meurthe-et-Moselle department, where the first domestic case was found; light gray shading indicates departments where clinical cases were found during January—March ; and white indicates departments where no clinical cases occurred during January—March These results suggest similar spread of SBV among red deer and domestic livestock during fall at the department level.
In , no evidence of abortions or malformations was reported in red deer or other native wildlife ruminant species within the populations monitored by wildlife biologists or zoo veterinarians in France S.
Rossi, A. Decors, A. However, specific studies exploring the effect of SBV on the reproductive success of wild species are still lacking. This study provides a preliminary view of SBV spread among wild cervids in France during — Our data also show the match of SBV spread among red deer and domestic flocks at the level of the department and highlight the perspective that red deer can be a sentinel of SBV spread for livestock. Further studies that encompass several years and include a larger number of species and localities would help provide a more complete picture of virus spread and risk factors in wildlife Her research interests focus on virology and microbiology, especially on emerging pathogens such as Schmallenberg virus.
Such assays first became commercially available in , but older assays that do not accurately distinguish HSV-1 from HSV-2 antibody despite claims to the contrary remain on the market ; providers should specifically request serologic type-specific glycoprotein G gG -based assays when serology is performed for their patients Both laboratory-based assays and point-of-care tests that provide results for HSV-2 antibodies from capillary blood or serum during a clinic visit are available.
False-positive results can occur, especially in patients with a low likelihood of HSV infection. Repeat or confirmatory testing might be indicated in some settings, especially if recent acquisition of genital herpes is suspected. IgM testing for HSV is not useful, because the IgM tests are not type-specific and might be positive during recurrent episodes of herpes Because nearly all HSV-2 infections are sexually acquired, the presence of type-specific HSV-2 antibody implies anogenital infection.
In this instance, education and counseling appropriate for persons with genital herpes should be provided. The presence of HSV-1 antibody alone is more difficult to interpret.
Lack of symptoms in an HSV-1 seropositive person does not distinguish anogenital from orolabial or cutaneous infection, and regardless of site of infection, these persons remain at risk for acquiring HSV Type-specific HSV serologic assays might be useful in the following scenarios: 1 recurrent genital symptoms or atypical symptoms with negative HSV cultures; 2 a clinical diagnosis of genital herpes without laboratory confirmation; or 3 a partner with genital herpes.
Antiviral chemotherapy offers clinical benefits to most symptomatic patients and is the mainstay of management. Counseling regarding the natural history of genital herpes, sexual and perinatal transmission, and methods to reduce transmission is integral to clinical management. Systemic antiviral drugs can partially control the signs and symptoms of herpes episodes when used to treat first clinical and recurrent episodes, or when used as daily suppressive therapy.
However, these drugs neither eradicate latent virus nor affect the risk, frequency, or severity of recurrences after the drug is discontinued. Randomized trials have indicated that three antiviral medications provide clinical benefit for genital herpes: acyclovir, valacyclovir, and famciclovir Valacyclovir is the valine ester of acyclovir and has enhanced absorption after oral administration.
Famciclovir also has high oral bioavailability. Topical therapy with antiviral drugs offers minimal clinical benefit, and its use is discouraged. Newly acquired genital herpes can cause a prolonged clinical illness with severe genital ulcerations and neurologic involvement. Even persons with first-episode herpes who have mild clinical manifestations initially can develop severe or prolonged symptoms.
Therefore, all patients with first episodes of genital herpes should receive antiviral therapy. Acyclovir mg orally three times a day for days. Almost all persons with symptomatic first-episode genital HSV-2 infection subsequently experience recurrent episodes of genital lesions; recurrences are less frequent after initial genital HSV-1 infection. Intermittent asymptomatic shedding occurs in persons with genital HSV-2 infection, even in those with longstanding or clinically silent infection.
Antiviral therapy for recurrent genital herpes can be administered either as suppressive therapy to reduce the frequency of recurrences or episodically to ameliorate or shorten the duration of lesions. Some persons, including those with mild or infrequent recurrent outbreaks, benefit from antiviral therapy; therefore, options for treatment should be discussed.
Many persons might prefer suppressive therapy, which has the additional advantage of decreasing the risk for genital HSV-2 transmission to susceptible partners , Treatment also is effective in patients with less frequent recurrences.
Safety and efficacy have been documented among patients receiving daily therapy with acyclovir for as long as 6 years and with valacyclovir or famciclovir for 1 year , Quality of life is improved in many patients with frequent recurrences who receive suppressive therapy rather than episodic treatment.
The frequency of recurrent genital herpes outbreaks diminishes over time in many patients, and the patient's psychological adjustment to the disease might change.
Therefore, periodically during suppressive treatment e. Treatment with valacyclovir mg daily decreases the rate of HSV-2 transmission in discordant, heterosexual couples in which the source partner has a history of genital HSV-2 infection Such couples should be encouraged to consider suppressive antiviral therapy as part of a strategy to prevent transmission, in addition to consistent condom use and avoidance of sexual activity during recurrences.
Suppressive antiviral therapy also is likely to reduce transmission when used by persons who have multiple partners including MSM and by those who are HSV-2 seropositive without a history of genital herpes.
Acyclovir, famciclovir, and valacyclovir appear equally effective for episodic treatment of genital herpes, but famciclovir appears somewhat less effective for suppression of viral shedding , Ease of administration and cost also are important considerations for prolonged treatment.
Effective episodic treatment of recurrent herpes requires initiation of therapy within 1 day of lesion onset or during the prodrome that precedes some outbreaks. The patient should be provided with a supply of drug or a prescription for the medication with instructions to initiate treatment immediately when symptoms begin. Famciclovir mg once, followed by mg twice daily for 2 days.
Intravenous IV acyclovir therapy should be provided for patients who have severe HSV disease or complications that necessitate hospitalization e. Acyclovir dose adjustment is recommended for impaired renal function.
Counseling of infected persons and their sex partners is critical to the management of genital herpes. The goals of counseling include 1 helping patients cope with the infection and 2 preventing sexual and perinatal transmission , Although initial counseling can be provided at the first visit, many patients benefit from learning about the chronic aspects of the disease after the acute illness subsides.
Although the psychological effect of a serologic diagnosis of HSV-2 infection in a person with asymptomatic or unrecognized genital herpes appears minimal and transient , some HSV-infected persons might express anxiety concerning genital herpes that does not reflect the actual clinical severity of their disease; the psychological effect of HSV infection frequently is substantial.
Common concerns regarding genital herpes include the severity of initial clinical manifestations, recurrent episodes, sexual relationships and transmission to sex partners, and ability to bear healthy children.
The misconception that HSV causes cancer should be dispelled. Persons who have genital herpes should be educated concerning the natural history of the disease, with emphasis on the potential for recurrent episodes, asymptomatic viral shedding, and the attendant risks of sexual transmission.
Persons experiencing a first episode of genital herpes should be advised that suppressive therapy is available and effective in preventing symptomatic recurrent episodes and that episodic therapy often is useful in shortening the duration of recurrent episodes.
All persons with genital HSV infection should be encouraged to inform their current sex partners that they have genital herpes and to inform future partners before initiating a sexual relationship. Sexual transmission of HSV can occur during asymptomatic periods. Asymptomatic viral shedding is more frequent in genital HSV-2 infection than genital HSV-1 infection and is most frequent during the first 12 months after acquiring HSV All persons with genital herpes should remain abstinent from sexual activity with uninfected partners when lesions or prodromal symptoms are present.
The risk for HSV-2 sexual transmission can be decreased by the daily use of valacyclovir by the infected person. Episodic therapy does not reduce the risk for transmission and its use should be discouraged for this purpose among persons whose partners might be at risk for HSV-2 acquisition. Infected persons should be informed that male latex condoms, when used consistently and correctly, might reduce the risk for genital herpes transmission Sex partners of infected persons should be advised that they might be infected even if they have no symptoms.
Type-specific serologic testing of the asymptomatic partners of persons with genital herpes is recommended to determine whether such partners are already HSV seropositive or whether risk for acquiring HSV exists. The risk for neonatal HSV infection should be explained to all persons, including men. Pregnant women and women of childbearing age who have genital herpes should inform their providers who care for them during pregnancy and those who will care for their newborn infant about their infection.
Pregnant women who are not known to be infected with HSV-2 should be advised to abstain from intercourse with men who have genital herpes during the third trimester of pregnancy. Similarly, pregnant women who are not known to be infected with HSV-1 should be counseled to avoid genital exposure to HSV-1 during the third trimester e.
Asymptomatic persons diagnosed with HSV-2 infection by type-specific serologic testing should receive the same counseling messages as persons with symptomatic infection. In addition, such persons should be educated about the clinical manifestations of genital herpes. Patients should be informed that suppressive antiviral therapy does not reduce the increased risk for HIV acquisition associated with HSV-2 infection , The sex partners of patients who have genital herpes can benefit from evaluation and counseling.
Symptomatic sex partners should be evaluated and treated in the same manner as patients who have genital lesions. Asymptomatic sex partners of patients who have genital herpes should be questioned concerning histories of genital lesions and offered type-specific serologic testing for HSV infection. Allergic and other adverse reactions to acyclovir, valacyclovir, and famciclovir are rare.
Desensitization to acyclovir has been described Immunocompromised patients can have prolonged or severe episodes of genital, perianal, or oral herpes. Whereas antiretroviral therapy reduces the severity and frequency of symptomatic genital herpes, frequent subclinical shedding still occurs Clinical manifestations of genital herpes might worsen during immune reconstitution after initiation of antiretroviral therapy.
Suppressive or episodic therapy with oral antiviral agents is effective in decreasing the clinical manifestations of HSV among HIV-positive persons The extent to which suppressive antiviral therapy will decrease HSV transmission from this population is unknown. HSV type-specific serologies can be offered to HIV-positive persons during their initial evaluation if infection status is unknown, and suppressive antiviral therapy can be considered in those who have HSV-2 infection.
Acyclovir, valacyclovir, and famciclovir are safe for use in immunocompromised patients in the doses recommended for treatment of genital herpes. If lesions persist or recur in a patient receiving antiviral treatment, HSV resistance should be suspected and a viral isolate should be obtained for sensitivity testing Such persons should be managed in consultation with an HIV specialist, and alternate therapy should be administered.
All acyclovir-resistant strains are resistant to valacyclovir, and the majority are resistant to famciclovir. These topical preparations should be applied to the lesions once daily for 5 consecutive days. Clinical management of antiviral resistance remains challenging among HIV-infected patients, and other preventative approaches might be necessary. However, experience with another group of immunocompromised persons hematopoietic stem-cell recipients demonstrated that persons receiving daily suppressive antiviral therapy were less likely to develop acyclovir-resistant HSV compared with those who received episodic therapy with outbreaks Most mothers of infants who acquire neonatal herpes lack histories of clinically evident genital herpes However, because recurrent genital herpes is much more common than initial HSV infection during pregnancy, the proportion of neonatal HSV infections acquired from mothers with recurrent herpes is substantial.
Prevention of neonatal herpes depends both on preventing acquisition of genital HSV infection during late pregnancy and avoiding exposure of the infant to herpetic lesions during delivery. Because the risk for herpes is high in infants of women who acquire genital HSV during late pregnancy, these women should be managed in consultation with an infectious disease specialist.
Women without known genital herpes should be counseled to abstain from intercourse during the third trimester with partners known or suspected of having genital herpes. In addition, pregnant women without known orolabial herpes should be advised to abstain from receptive oral sex during the third trimester with partners known or suspected to have orolabial herpes. Some specialists believe that type-specific serologic tests are useful to identify pregnant women at risk for HSV infection and to guide counseling regarding the risk for acquiring genital herpes during pregnancy and that such testing should be offered to uninfected women whose sex partner has HSV infection.
However, the effectiveness of antiviral therapy to decrease the risk for HSV transmission to pregnant women by infected partners has not been studied. All pregnant women should be asked whether they have a history of genital herpes.
At the onset of labor, all women should be questioned carefully about symptoms of genital herpes, including prodromal symptoms, and all women should be examined carefully for herpetic lesions. Women without symptoms or signs of genital herpes or its prodrome can deliver vaginally.
Although cesarean section does not completely eliminate the risk for HSV transmission to the infant, women with recurrent genital herpetic lesions at the onset of labor should deliver by cesarean section to prevent neonatal HSV infection. The safety of systemic acyclovir, valacyclovir, and famciclovir therapy in pregnant women has not been definitively established. Available data do not indicate an increased risk for major birth defects compared with the general population in women treated with acyclovir during the first trimester findings that provide assurance to women who have had prenatal exposure to acyclovir.
However, data regarding prenatal exposure to valacyclovir and famciclovir are too limited to provide useful information on pregnancy outcomes. Acyclovir can be administered orally to pregnant women with first episode genital herpes or severe recurrent herpes and should be administered IV to pregnant women with severe HSV infection.
Acyclovir treatment late in pregnancy reduces the frequency of cesarean sections among women who have recurrent genital herpes by diminishing the frequency of recurrences at term ; the effect of antiviral therapy late in pregnancy on the incidence of neonatal herpes is not known. No data support the use of antiviral therapy among HSV seropositive women without a history of genital herpes. Infants exposed to HSV during birth, as documented by maternal virologic testing or presumed by observation of maternal lesions, should be followed carefully in consultation with a pediatric infectious disease specialist.
Surveillance cultures of mucosal surfaces to detect HSV infection might be considered before the development of clinical signs of neonatal herpes. In addition, administration of acyclovir might be considered for infants born to women who acquired HSV near term because the risk for neonatal herpes is high for these infants.
All infants who have neonatal herpes should be promptly evaluated and treated with systemic acyclovir. Granuloma inguinale is a genital ulcerative disease caused by the intracellular gram-negative bacterium Klebsiella granulomatis formerly known as Calymmatobacterium granulomatis. The disease occurs rarely in the United States, although it is endemic in some tropical and developing areas, including India; Papua, New Guinea; the Caribbean; central Australia; and southern Africa , Clinically, the disease is commonly characterized as painless, slowly progressive ulcerative lesions on the genitals or perineum without regional lymphadenopathy; subcutaneous granulomas pseudoboboes might also occur.
The lesions are highly vascular i. The clinical presentation also can include hypertrophic, necrotic, or sclerotic variants. Extragenital infection can occur with extension of infection to the pelvis, or it can disseminate to intraabdominal organs, bones, or the mouth.
The lesions also can develop secondary bacterial infection and can coexist with other sexually transmitted pathogens. The causative organism is difficult to culture, and diagnosis requires visualization of dark-staining Donovan bodies on tissue crush preparation or biopsy. No FDA-cleared molecular tests for the detection of K.
Several antimicrobial regimens have been effective, but only a limited number of controlled trials have been published Treatment has been shown to halt progression of lesions, and healing typically proceeds inward from the ulcer margins; prolonged therapy is usually required to permit granulation and reepithelialization of the ulcers. Relapse can occur months after apparently effective therapy.
Doxycycline mg orally twice a day for at least 3 weeks and until all lesions have completely healed. Azithromycin 1 g orally once per week for at least 3 weeks and until all lesions have completely healed. Ciprofloxacin mg orally twice a day for at least 3 weeks and until all lesions have completely healed.
Erythromycin base mg orally four times a day for at least 3 weeks and until all lesions have completely healed. The addition of an aminoglycoside e. Persons who have had sexual contact with a patient who has granuloma inguinale within the 60 days before onset of the patient's symptoms should be examined and offered therapy. However, the value of empiric therapy in the absence of clinical signs and symptoms has not been established.
Pregnancy is a relative contraindication to the use of sulfonamides. Pregnant and lactating women should be treated with the erythromycin regimen, and consideration should be given to the addition of a parenteral aminoglycoside e. Azithromycin might prove useful for treating granuloma inguinale during pregnancy, but published data are lacking. Doxycycline and ciprofloxacin are contraindicated in pregnant women.
Persons with both granuloma inguinale and HIV infection should receive the same regimens as those who are HIV negative; however, the addition of a parenteral aminoglycoside e. Lymphogranuloma venereum LGV is caused by C. A self-limited genital ulcer or papule sometimes occurs at the site of inoculation. However, by the time patients seek care, the lesions have often disappeared.
LGV is an invasive, systemic infection, and if it is not treated early, LGV proctocolitis can lead to chronic, colorectal fistulas and strictures. Genital and colorectal LGV lesions can also develop secondary bacterial infection or can be coinfected with other sexually and nonsexually transmitted pathogens.
Diagnosis is based on clinical suspicion, epidemiologic information, and the exclusion of other etiologies for proctocolitis, inguinal lymphadenopathy, or genital or rectal ulcers. Genital and lymph node specimens i. NAATs for C. Additional molecular procedures e. Comparative data between types of serologic tests are lacking, and the diagnostic utility of serologic methods other than complement fixation and some microimmunofluorescence procedures has not been established.
Serologic test interpretation for LGV is not standardized, tests have not been validated for clinical proctitis presentations, and C. In the absence of specific LGV diagnostic testing, patients with a clinical syndrome consistent with LGV, including proctocolitis or genital ulcer disease with lymphadenopathy, should be treated for LGV as described in this report.
Treatment cures infection and prevents ongoing tissue damage, although tissue reaction to the infection can result in scarring. Doxycycline is the preferred treatment.
Although clinical data are lacking, azithromycin 1 g orally once weekly for 3 weeks is probably effective based on its chlamydial antimicrobial activity. Fluoroquinolone-based treatments might also be effective, but extended treatment intervals are likely required. Persons who have had sexual contact with a patient who has LGV within the 60 days before onset of the patient's symptoms should be examined, tested for urethral or cervical chlamydial infection, and treated with a chlamydia regimen azithromycin 1 gm orally single dose or doxycycline mg orally twice a day for 7 days.
Pregnant and lactating women should be treated with erythromycin. Azithromycin might prove useful for treatment of LGV in pregnancy, but no published data are available regarding its safety and efficacy. Doxycycline is contraindicated in pregnant women. Prolonged therapy might be required, and delay in resolution of symptoms might occur. Syphilis is a systemic disease caused by Treponema pallidum. On the basis of clinical findings, the disease has been divided into a series of overlapping stages, which are used to help guide treatment and follow-up.
Persons who have syphilis might seek treatment for signs or symptoms of primary infection i. Latent infections i. Latent syphilis acquired within the preceding year is referred to as early latent syphilis; all other cases of latent syphilis are either late latent syphilis or latent syphilis of unknown duration. Treatment for both late latent syphilis and tertiary syphilis might require a longer duration of therapy because organisms might be dividing more slowly; however, the validity of this concept has not been assessed.
Darkfield examinations and tests to detect T. Although no T. A presumptive diagnosis of syphilis is possible with the use of two types of serologic tests: 1 nontreponemal tests e. The use of only one type of serologic test is insufficient for diagnosis, because each type of test has limitations, including the possibility of false-positive test results in persons without syphilis.
False-positive nontreponemal test results can be associated with various medical conditions unrelated to syphilis, including autoimmune conditions, older age, and injection-drug use , ; therefore, persons with a reactive nontreponemal test should receive a treponemal test to confirm the diagnosis of syphilis.
Nontreponemal test antibody titers may correlate with disease activity, and results should be reported quantitatively. A fourfold change in titer, equivalent to a change of two dilutions e. Sequential serologic tests in individual patients should be performed using the same testing method e.
Nontreponemal test titers usually decline after treatment and might become nonreactive with time; however, in some persons, nontreponemal antibodies can persist for a long period of time a response referred to as the "serofast reaction. Treponemal test antibody titers should not be used to assess treatment response. Some clinical laboratories and blood banks have begun to screen samples using treponemal tests, typically by EIA or chemiluminescence immunoassays , This strategy will identify both persons with previous treatment for syphilis and persons with untreated or incompletely treated syphilis.
The positive predictive value for syphilis associated with a treponemal screening test result might be lower among populations with a low prevalence of syphilis. Persons with a positive treponemal screening test should have a standard nontreponemal test with titer performed reflexively by the laboratory to guide patient management decisions.
If the nontreponemal test is negative, then the laboratory should perform a different treponemal test preferably one based on different antigens than the original test to confirm the results of the initial test. If a second treponemal test is positive, persons with a history of previous treatment will require no further management unless sexual history suggests likelihood of re-exposure. Those without a history of treatment for syphilis should be offered treatment.
Unless history or results of a physical examination suggest a recent infection, previously untreated persons should be treated for late latent syphilis. If the second treponemal test is negative, further evaluation or treatment is not indicated.
For most HIV-infected persons, serologic tests are accurate and reliable for the diagnosis of syphilis and for following a patient's response to treatment.
However, atypical syphilis serologic test results i. When serologic tests do not correspond with clinical findings suggestive of early syphilis, use of other tests e. Clinical signs of neurosyphilis i. Laboratory testing is helpful in supporting the diagnosis of neurosyphilis; however, no single test can be used to diagnose neurosyphilis in all instances. Cerebrospinal fluid CSF laboratory abnormalities are common in persons with early syphilis. When reactive in the absence of substantial contamination of CSF with blood, it is considered diagnostic of neurosyphilis; however in early syphilis, it can be of unknown prognostic significance Most other tests are both insensitive and nonspecific and must be interpreted in relation to other test results and the clinical assessment.
Therefore, the laboratory diagnosis of neurosyphilis usually depends on various combinations of reactive serologic test results, CSF cell count or protein, and a reactive CSF-VDRL with or without clinical manifestations. Penicillin G, administered parenterally, is the preferred drug for treating all stages of syphilis. The preparation used i. Selection of the appropriate penicillin preparation is important, because T. Combinations of benzathine penicillin, procaine penicillin, and oral penicillin preparations are not considered appropriate for the treatment of syphilis.
Reports have indicated that practitioners have inadvertently prescribed combination benzathine-procaine penicillin Bicillin C-R instead of the standard benzathine penicillin product Bicillin L-A widely used in the United States. Practitioners, pharmacists, and purchasing agents should be aware of the similar names of these two products to avoid using the inappropriate combination therapy agent for treating syphilis The effectiveness of penicillin for the treatment of syphilis was well established through clinical experience even before the value of randomized controlled clinical trials was recognized.
Therefore, nearly all the recommendations for the treatment of syphilis are based not only on clinical trials and observational studies, but approximately 50 years of clinical experience. Parenteral penicillin G is the only therapy with documented efficacy for syphilis during pregnancy. Pregnant women with syphilis in any stage who report penicillin allergy should be desensitized and treated with penicillin see Management of Patients Who Have a History of Penicillin Allergy.
The Jarisch-Herxheimer reaction is an acute febrile reaction frequently accompanied by headache, myalgia, fever, and other symptoms that usually occur within the first 24 hours after the initiation of any therapy for syphilis. Patients should be informed about this possible adverse reaction. The Jarisch-Herxheimer reaction occurs most frequently among patients who have early syphilis, presumably because bacterial burdens are higher during these stages.
Antipyretics can be used to manage symptoms, but they have not been proven to prevent this reaction. The Jarisch-Herxheimer reaction might induce early labor or cause fetal distress in pregnant women, but this should not prevent or delay therapy see Syphilis During Pregnancy. Sexual transmission of T. Although such manifestations are uncommon after the first year of infection, persons exposed sexually to a patient who has syphilis in any stage should be evaluated clinically and serologically and treated with a recommended regimen, according to the following recommendations:.
Persons who were exposed within the 90 days preceding the diagnosis of primary, secondary, or early latent syphilis in a sex partner might be infected even if seronegative; therefore, such persons should be treated presumptively. For purposes of partner notification and presumptive treatment of exposed sex partners, patients with syphilis of unknown duration who have high nontreponemal serologic test titers i. For the purpose of determining a treatment regimen, however, serologic titers should not be used to differentiate early from late latent syphilis see Latent Syphilis, Treatment.
Long-term sex partners of patients who have latent syphilis should be evaluated clinically and serologically for syphilis and treated on the basis of the evaluation findings. Sexual partners of infected patients should be considered at risk and provided treatment if they have had sexual contact with the patient within 3 months plus the duration of symptoms for patients diagnosed with primary syphilis, 6 months plus duration of symptoms for those with secondary syphilis, and 1 year for patients with early latent syphilis.
Parenteral penicillin G has been used effectively for more than 50 years to achieve clinical resolution i. However, no comparative trials have been adequately conducted to guide the selection of an optimal penicillin regimen i. Substantially fewer data are available for nonpenicillin regimens. Available data demonstrate that additional doses of benzathine penicillin G, amoxicillin, or other antibiotics in early syphilis primary, secondary, and early latent do not enhance efficacy, regardless of HIV status.
Children with acquired primary or secondary syphilis should be evaluated e. All persons who have syphilis should be tested for HIV infection. In geographic areas in which the prevalence of HIV is high, persons who have primary syphilis should be retested for HIV after 3 months if the first HIV test result was negative.
Patients who have syphilis and symptoms or signs suggesting neurologic disease e. Treatment should be guided by the results of this evaluation. Invasion of CSF by T. Therefore, in the absence of clinical neurologic findings, no evidence exists to support variation from the recommended treatment regimen for early syphilis. Symptomatic neurosyphilis develops in only a limited number of persons after treatment with the penicillin regimens recommended for primary and secondary syphilis.
Therefore, unless clinical signs or symptoms of neurologic or ophthalmic involvement are present or treatment failure is documented, routine CSF analysis is not recommended for persons who have primary or secondary syphilis. Treatment failure can occur with any regimen. However, assessing response to treatment frequently is difficult, and definitive criteria for cure or failure have not been established.
In addition, nontreponemal test titers might decline more slowly for persons who previously have had syphilis Clinical and serologic evaluation should be performed 6 months and 12 months after treatment; more frequent evaluation might be prudent if follow-up is uncertain.
Patients who have signs or symptoms that persist or recur or who have a sustained fourfold increase in nontreponemal test titer i. These patients should be retreated and reevaluated for HIV infection. Because treatment failure usually cannot be reliably distinguished from reinfection with T. Persons whose titers do not decline should be reevaluated for HIV infection. Optimal management of such patients is unclear. At a minimum, these patients should receive additional clinical and serologic follow-up.
If additional follow-up cannot be ensured, retreatment is recommended. Because treatment failure might be the result of unrecognized CNS infection, CSF examination can be considered in such situations.
