Syphilis management and treatment

Ocular Jarisch-Herxheimer Reaction in the Treatment of Ocular Syphilis: A Case Report and Review of the Literature

Jarisch-Herxheimer reaction (JHR) is a transient clinical phenomenon in patients with syphilis who receive antibiotic treatment. A 31-year-old man with an underlying HIV infection presented with worsening vision in the right eye two days after being treated with oral doxycycline for presumed left-eye neuroretinitis. Prior history revealed two episodes of penile discharge and ulcers that were not investigated. Examination showed bilateral optic disc swelling with right eye placoid chorioretinitis around the macula. Optical coherence tomography (OCT) demonstrated right macular edema and left macular thinning. Blood investigations confirmed syphilis infection. Subsequently, the patient was scheduled for a contrasted brain CT with oral steroid coverage due to underlying allergies. His vision incidentally improved soon after the short course of steroids. Repeated OCT demonstrated marked improvement of right macular edema, which we believe was secondary to JHR initiated by the earlier doxycycline treatment. Following oral steroid addition, improvement in vision and ocular findings were seen. At six-month post-treatment, there was right macular atrophy as a sequela of the macular edema. Ophthalmologists should be aware of ocular-related JHR complications, particularly in potentiating macular atrophy following macular edema upon initiating antibiotic treatment in syphilitic disease.

Investigating latent syphilis in HIV treatment-experienced Ethiopians and response to therapy

Objectives

We investigated people with HIV (PWH) receiving combination antiretroviral therapy (cART) for latent syphilis infection prevalence, risk factors, treatment response, and neurosyphilis.

Methods

A prospective follow-up study was conducted on PWH and latent syphilis. The cases were randomly assigned to receive either benzathine penicillin G (BPG) or doxycycline (DOXY), and the posttreatment response was evaluated after 12 and 24 months. The traditional algorithm was used for serodiagnosis, and a semi-quantitative rapid plasma reagin (RPR) test monitored disease activity and treatment effectiveness.

Results

Of the 823 participants, 64.8% were women, and the mean age was 41.7±10 years. Thirty-one (3.8%) of the participants (22 males and nine females) had latent syphilis. The risk factors were male sex (aOR = 3.14), increasing age (aOR = 1.04 per year), and cART duration (aOR = 1.01 per month). Baseline RPR titers were: ≤1:4 in 19 (61.3%), between 1:8 and 1:32 in 10 (32.2%), and >1:32 in 2 (6.4%). None of the seven cerebrospinal fluid analyses supported a neurosyphilis diagnosis. In the 12^th month of treatment, 27 (87.1%) had adequate serological responses, three (9.7%) had serological nonresponse, and one (3.2%) had treatment failure. Syphilis treatment was repeated in the last four cases with the alternative drug. In terms of adequate serologic response, both therapies were comparable at the 12^th month, p = 0.37. All cases responded to treatment in the 24^th month.

Conclusion

In PWH receiving cART, latent syphilis occurred more in men than women, suggesting an investigation of sexual practices and the impact of antenatal syphilis screening. Syphilis disease activity reduces in the latent stage. Therefore, the routine cerebrospinal fluid analysis contributes little to the diagnosis of asymptomatic neurosyphilis and the treatment success of latent syphilis. DOXY is an alternative to BPG, and cART improves serologic response to latent syphilis treatment.

Paradoxical reactions in ocular tuberculosis

Paradoxical reactions following initiation of anti-tubercular therapy have been documented most often in extrapulmonary tuberculosis. A combination of factors such as delayed hypersensitivity, decreased suppressor mechanisms, and an increased response to mycobacterial antigens mediated by the host’s immune system have been implicated in the development of these reactions. Similar worsening in patients with ocular tuberculosis while on treatment has been described. It is therefore important for the clinician to be aware of this occurrence, as prompt recognition and timely institution of corticosteroids and immunosuppressants can lead to restoration of vision. In these patients, an alteration or discontinuation of anti-tubercular therapy may not be indicated.

UK national guidelines on the management of syphilis 2015

These guidelines are an update for 2015 of the 2008 UK guidelines for the management of syphilis. The writing group have piloted the new BASHH guideline methodology, notably using the GRADE system for assessing evidence and making recommendations. We have made significant changes to the recommendations for screening infants born to mothers with positive syphilis serology and to facilitate accurate and timely communication between the teams caring for mother and baby we have developed a birth plan. Procaine penicillin is now an alternative, not preferred treatment, for all stages of syphilis except neurosyphilis, but the length of treatment for this is shortened. Other changes are summarised at the start of the guideline.

Fatal visceral leishmaniasis, with massive bone-marrow infection, in an immunosuppressed but HIV-negative Spanish patient, after the initiation of treatment with meglumine antimoniate

Although visceral leishmaniasis is often fatal in the developing world, Leishmania-attributable deaths in Europe are relatively rare and nowadays almost always linked to HIV infection. In Spain, however, a HIV-negative man with a history of chronic obstructive pulmonary disease and prednisone treatment was recently hospitalized because of hypotension and asthenia. Although the patient was afebrile, a bone-marrow aspirate, collected after thrombo- and leuco-cytopenia had been observed, was found to contain huge numbers of amastigotes. A course of antileishmanial treatment with meglumine antimoniate was initiated but the patient went into refractory shock and died within 6 h. The significance of this case, in terms of the routine investigation and treatment of immunosuppressed patients who may have leishmaniasis, is discussed.

Experience of meningovascular syphilis in human immunodeficiency virus infected patient

Since the start of the antibiotic era, syphilis has become rare. However, in recent times, it has tended to be prevalent concomitantly with human immunodeficiency virus (HIV) infection and coinfection in North America and Europe. Now, such cases are expected to increase in elsewhere including Korea. A 40-year-old male patient visited hospital complaining of a headache for about one month. Brain computed tomography and magnetic resonance imaging, showed leptomeninged enhancing mass with edema an right porisylvian region, which was suspected to be glioma. Patient underwent a blood test and was diagnosed with syphilis and acquired immune deficiency syndrome. Partial cortical and subcortical resection were performed after small craniotomy. The dura was thick, adhered to the brain cortex, and was accompanied by hyperemic change of the cortex. The pathologic diagnosis was meningovascular syphilis (MS) in HIV infection. After the operation, the patient was treated with aqueous penicillin G. Thereafter, he had no neurological deficit except intermittent headache. At first, this case was suspected to be glioma, but it was eventually diagnosed as MS in HIV coinfection. At this point the case was judged to be worth reporting.

A review of pediatric uveitis: Part I. Infectious causes and the masquerade syndromes

Uveitis is a manifestation of complex processes that can represent an infectious or a purely immune system modulated condition and may have grave effects on the eye. Much of the morbidity in these conditions is the result of the immune response to these stimuli. These infectious diseases may be successfully treated by addressing the inciting organism with recognized interventions. Treatment of the immune response to the organism often must be pursued simultaneously to minimize long-term complications caused by structural changes within the eye. Assisting the individual's immune response to eliminate the organism while minimizing the immune response's damaging effects remains a unique challenge drawing on both the science and the art of medicine. Several non-infectious conditions that are not autoimmune diseases may commonly masquerade as uveitis, leading to delays in appropriate treatment.

[Significance of the combined tests application in serum and liquor of patients with suspected neurosyphilis]

BACKGROUND

:Tertiary syphilis develops in 8-40% of untreated patients. It is most commonly manifested in the form of neurosyphilis, which can be asymptomatic taking the form of tabes dorsalis or progressive paralyze. Nowadays, in the developed countries, progressive paralyze is a rather rare disease, although the incidence of this disease has been rising within the last decades.

CASE REPORT

We reported a 74-year-old male with the clinical image of dementia showing psychotic symptoms. On cytobiochemical examination of cerebrospinal liquor, hyper-proteinorhacmia of 0.70 g/1l with the normal number of cells was revealed. Computed tomography of the brain showed the marked cortical cerebral and cerebellar reduction changes with multiple ischemic lesions. Within a routine examination of patients with demention, we performed serologic reactions to syphilis out of which the Veneral Disease Researc Laboratory (VDRL) test in serum and liquor was unreactive, while the Treponema pallidum hemagglutination (TPNA) test in serum and liquor was positive. Positivity in serum and liquor was additionally confirmed by the Western blot method and fluoroscent treponema antibody (FTA) test. The treatment with benzathine fenylpenicilline 2.4 g once weekly resulted in significant improving the psychotic symptoms of the disease even after two weeks.

CONCLUSION

This case report showed that within the differential diagnostics in patients with demention or psychotic disorder it is obligatory to consider syphilis of the nervous system, as well as to apply a combination of various tests which, besides the typical liquor findings, significantly improve the accuracy of diagnosis. Such approach is especially important regarding the fact that neurosyphilis can remain clinically quite asymptomatic for a long period, which could lead to late therapy, while, on the contrary, an adequate and timely treatment can contribute to a significant recovery of any patients.

[Syphilis treatment. German and international guidelines--a comparison]

Guidelines are an important instrument for improving the quality of medical care. In 2001, the German STD Society (DSTDG) published guidelines for syphilis diagnostics and treatment. For two reasons, these guidelines had to be reviewed urgently: Firstly, there is an obvious "renaissance" of syphilis among men having sex with men, which is complicated by a frequent comorbidity with HIV infection. Secondly, the standard drug for syphilis treatment in Germany, clemizole penicillin, has no longer been available since July 2003. In this article, the new German guidelines for syphilis treatment 2004, published by the DSTDG, are compared with other syphilis guidelines, which are valid for the European countries, i.e., the CDC, UK, Russian, and European guidelines 2002.

The eye in systemic infection

Bacterial, fungal, viral, and parasitic pathogens all cause systemic infection and can spread to the eye. Dissemination of pathogens via the bloodstream can lead to direct involvement of the eye. Visual loss is common in bacterial or fungal endophthalmitis, and toxoplasmosis is a major cause of ocular morbidity and poor vision after congenital or acquired infection. Some infections cause intraocular damage by indirect mechanisms (eg, HIV-mediated immunosuppression), leading to opportunistic infections such as cytomegalovirus infection, periocular nerve involvement due to leprosy, and hypersensitivity reactions in tuberculosis. Eye symptoms might indicate the outcome of an underlying infection, such as development of retinal ischaemia in severe malaria, which is associated with a poor prognosis. Successful outcome for patients with ocular infection depends on close collaboration between clinicians identifying and treating underlying disease, specialist ophthalmic review, and ophthalmic interventional skills (when needed).

Congenital syphilis in Russia: the value of counting epidemiologic cases and clinical cases

BACKGROUND

Congenital syphilis (CS) reports in Russia increased 26-fold from 1991 to 1999. Case reports included only infants who were clinical cases, had persistent serologic changes, or confirmed syphilitic stillbirth. Although not reported, policies stipulate that infants of inadequately treated or untreated mothers receive preventive penicillin treatment.

GOAL

We examined whether risk factors and consequences for epidemiologic cases of CS (infants of inadequately treated mothers) resembled those of clinical cases and differed from those of noncases (infants of adequately treated mothers).

STUDY DESIGN

A retrospective record review from Maternity Houses in 5 sites identified 715 syphilis-infected women who gave birth.

RESULTS

Among women with maternal syphilis, 11% (n = 81) of infants were clinical cases, 56% (n = 402) were epidemiologic cases, and 33% (n = 232) were noncases of CS. Compared with noncases, maternal risk factors for epidemiologic cases included nonresidence (P <0.01), late syphilis (P <0.01), unemployment (P <0.01), no prenatal care (P <0.01), and syphilis testing at >/=28 weeks (P <0.01). Each of these was also significant for being a clinical case. Associated consequences of CS for the epidemiologic cases included increases in stillbirth (P <0.01), preterm birth (P <0.01), low birth weight (P <0.01), transfer to a pediatric hospital (P <0.01), and abandonment (P <0.05). Each of these except stillbirth was significantly elevated among clinical cases. Nearly half of the epidemiologic cases had no record of any penicillin treatment for the infant. Epidemiologic cases were significantly more likely than noncases to have no clinical or laboratory follow up.

CONCLUSION

In Russia, maternal risk factors and perinatal consequences for epidemiologic cases of CS resembled those of clinical cases. Expanding national reporting to include epidemiologic cases would strengthen CS prevention and monitoring.
