Clinical characteristics and outcomes of people living with HIV and ocular syphilis during the COVID-19 health emergency.

BACKGROUND: The global shift in healthcare during the COVID-19 pandemic led to challenges in the care of people living with HIV. METHODS: We conducted a retrospective study that aimed to delineate sociodemographic, clinical characteristics and outcomes, of people living with HIV diagnosed with ocular syphilis. RESULTS: Fifty-three people living with HIV were identified with ocular syphilis. Thirty-eight (71.6%) presented ocular symptoms. Twenty-three (43.3%) underwent lumbar puncture, 5 (9.4%) were positive for neurosyphilis. Forty-seven (88.6%) received treatment, 32 (68%) received standard treatment with aqueous crystalline penicillin G, and 15 (31.9%) were treated with alternative regimens due to the impossibility of hospitalization. Six (11.3%) individuals were lost to follow-up and/or did not receive treatment. Eighteen (56.2%) out of 32 individuals in the aqueous crystalline penicillin G group experienced serological response, 5 (15.6%) experienced treatment failure, and 9 (28.1%) were lost to follow-up. In the alternative therapy group, 12 out of 15 individuals (80%) experienced serological response. One (6.7%) experienced treatment failure, and 2 (13.3%) were lost to follow-up. CONCLUSIONS: During the COVID-19 health emergency in Mexico, alternative treatments for ocular syphilis demonstrated favorable clinical outcomes amid challenges in accessing hospitalization.

The Great Mimicker: Secondary Syphilis-Associated Nephrotic Syndrome in an Adolescent Patient.

BACKGROUND: Syphilis is long regarded as the "great mimicker" for its variety of symptoms and clinical manifestations. Rarely, it can present with renal involvement, particularly nephrotic syndrome. This is an uncommon initial presentation, particularly in pediatrics. CASE REPORT: We present the case of a 17-year-old male adolescent who presented to the emergency department with a chief symptom of abdominal pain. In addition, he was found to have a number of stigmata characteristic of both syphilis and nephrotic syndrome, including a rash and diffuse edema, particularly in the lower extremities. This led to the diagnosis of nephrotic syndrome secondary to syphilis infection. Prompt diagnosis and treatment of syphilis resulted in resolution of both kidney injury and symptoms of the underlying infection. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the variety of manifestations of sexually transmitted infections, particularly in the pediatric population. It demonstrates how identifying syphilis as the inciting event led to the correct treatment management for the patient. This presentation serves to teach and remind emergency physicians of the wide-ranging presentations for sexually transmitted infections, particularly syphilis, and the necessity of obtaining a sexual history even in adolescent patients.

A rare case report of bilateral vestibulopathy due to otosyphilis.

RATIONALE: Bilateral vestibulopathy is an important cause of imbalance. There are multiple etiologies of bilateral vestibulopathy (BVP), but reports of BVP due to otosyphilis are rare. PATIENT CONCERNS: A 39-year-old male was referred to our medical center due to vertigo, persistent dizziness and gait disturbance for 2 months. DIAGNOSES: Bilateral vestibulopathy due to otosyphilis was considered in this case, as confirmed through analyses of vestibular function, laboratory tests, and penicillin treatment. INTERVENTIONS: The patient was was treated with a high dose of penicillin G (24 × 106 IU/d) for 14 days. OUTCOMES: The patient's symptoms had improved greatly following treatment, with dizziness and gait disturbance having completely resolved at 3 months following hospital discharge. LESSONS: Bilateral vestibulopathy should be considered when evaluating patients with acute or subacute persistent dizziness. Clinicians should also be aware of the potential for otosyphilis among patients who report BVP.

Syphilitic scleritis and episcleritis: A review.

Scleritis and episcleritis are rare, but potentially sight-threatening forms of syphilis. To provide a full description of this neglected subset of ocular syphilis, we evaluated the English literature for reports of syphilitic scleritis and episcleritis, recording the demographics, clinical characteristics, serological data, management practices, treatment responses, and visual outcomes. Previously published descriptions of 44 patients with syphilitic scleritis (50 eyes) and 9 patients with syphilitic episcleritis (14 eyes) were identified. The predominant type of scleritis was anterior scleritis, accounting for 92.9% of cases, with nodular anterior scleritis being the most frequent subtype at 58.1%. Almost one-quarter of patients were co-infected with human immunodeficiency virus (HIV). Initial misdiagnosis was common and led to delays in initiating treatment with appropriate antibiotics. Visual outcomes were often good in both scleritis and episcleritis, irrespective of HIV infection status, although complications including scleral thinning, keratitis, and uveitis, along with permanent visual loss and an association with neurosyphilis, were reported. Response to antibiotic treatment was typically rapid, often within 1 week. With the rising global incidence of syphilis, testing patients with scleritis or episcleritis for this infectious disease is important to ensure prompt diagnosis and treatment for best ocular and systemic outcomes.

Secondary syphilis presenting with alopecia and leukoderma in a stable HIV-positive patient in a resource-limited setting: a case report.

BACKGROUND: Syphilis is an infection caused by the bacteria Treponema pallidum. It is mainly transmitted through oral, vaginal and anal sex, in pregnancy and through blood transfusion. Syphilis develops in primary, secondary, latent and tertiary stages and presents with different clinical features at each stage. Infected patients can remain asymptomatic for several years and, without treatment, can, in extreme cases, manifest as damage in several organs and tissues, including the brain, nervous tissue, eyes, ear and soft tissues. In countries with a high human immunodeficiency virus (HIV) burden, syphilis increases the risk of HIV infections. We report the case of a young HIV-positive black woman who presented with alopecia and hypopigmentation as features of secondary syphilis. CASE PRESENTATION: A virologically suppressed 29-year-old woman on Anti-retroviral Therapy (ART) presented with a short history of generalized hair loss associated with a non-itchy maculopapular rash and skin depigmentation on the feet. Limited laboratory testing confirmed a diagnosis of secondary syphilis. She was treated with Benzathine Penicillin 2.4MU. After receiving three doses of the recommended treatment, the presenting features cleared, and the patient recovered fully. CONCLUSION: This case demonstrates the importance of a high index of clinical suspicion and testing for syphilis in patients presenting with atypical clinical features of secondary syphilis, such as hair loss and hypopigmentation. It also highlights the challenges in diagnosing and clinically managing syphilis in a resource-limited setting.

Beyond Tumors: Gastric Syphilis Emulating a Gastric Neoplasia.

We present the case of a 35-year-old male with a first-degree family history of gastric cancer (his father was diagnosed at the age of 45), who was presumed to have gastric cancer himself when evaluating the features of his upper endoscopy performed after hematemesis. Surprisingly, no cancer cells were found in the biopsies. Thanks to a different diagnostic suspicion subsequent to performing a full clinical history, a more favorable diagnosis was reached: gastric syphilis.

Syphilis and cardiovascular risk: a Taiwanese registry.

BACKGROUND AND AIMS: Studies on the impact of syphilis on the cardiovascular system in large populations are limited. This study investigated the effects of syphilis on cardiovascular outcomes. METHODS: Medical records from 2010 to 2015 were retrieved from the Taiwan National Health Insurance Research Database, linked to the Notifiable Infectious Diseases database from the Taiwan Centers for Disease Control. Patients with syphilis were identified, excluding those with missing information, under 20 years of age, or with a history of human immunodeficiency virus infection, acute myocardial infarction, heart failure, aortic regurgitation, replacement of the aortic valve, aneurysm and/or dissection of the aorta, atrial fibrillation, ischaemic stroke, haemorrhagic stroke, and venous thromboembolism. Primary outcomes included new-onset acute myocardial infarction, heart failure, aortic regurgitation, aneurysm and dissection of the aorta, atrial fibrillation, ischaemic stroke, haemorrhagic stroke, venous thromboembolism, cardiovascular death, and all-cause mortality. RESULTS: A total of 28 796 patients with syphilis were identified from 2010 to 2015. After exclusions and frequency matching, 20 601 syphilis patients and 20 601 non-syphilis patients were analysed. The relative rate (RR) was utilized in the analysis, as the competing risk of death was not considered. Compared with patients without syphilis, patients with syphilis had increased risks of acute myocardial infarction (RR 38%, 95% confidence interval [CI] 1.19-1.60, P < .001), heart failure (RR 88%, 95% CI 1.64-2.14, P < .001), aortic regurgitation (RR 81%, 95% CI 1.18-2.75, P = .006), atrial fibrillation (RR 45%, 95% CI 1.20-1.76, P < .001), ischaemic stroke (RR 68%, 95% CI 1.52-1.87, P < .001), haemorrhagic stroke (RR 114%, 95% CI 1.74-2.64, P < .001), venous thromboembolism (RR 67%, 95% CI 1.23-2.26, P = .001), cardiovascular death (RR 155%, 95% CI 2.11-3.08, P < .001), and all-cause death (RR 196%, 95% CI 2.74-3.19, P < .001) but not for aneurysm and dissection of the aorta. CONCLUSIONS: This study demonstrates that patients with syphilis have a higher risk of cardiovascular events and all-cause mortality compared with those without syphilis.

2023 Korean sexually transmitted infections guidelines for non-gonococcal bacterial infection (chlamydia, syphilis, etc.) by the Korean Association of Urogenital Tract Infection and Inflammation.

Non-gonococcal sexually transmitted infections (STIs) include chlamydia, syphilis, and chancroids. Chlamydia is the most common STI caused by Chlamydia trachomatis and is mainly transmitted through sexual intercourse or vertical transmission at birth. Although symptoms are mostly absent or mild, untreated chlamydial infections in females can lead to pelvic inflammatory disease, chronic pelvic pain, and infertility due to the narrowing of fallopian tubes. Syphilis is caused by Treponema pallidum and is divided into phase I, phase II, latent syphilis, and phase III. The incidence of syphilis, including congenital syphilis, has significantly increased in the United States in recent years. The chronic status of this disease can significantly increase morbidity and potentially affect almost all body organs, which, in rare cases, can lead to death. Additionally, untreated maternal syphilis can lead to fetal death and fatal congenital infections in newborns. Chancroid is an STI caused by Haemophilus ducreyi, and its prevalence is gradually decreasing in Korea and worldwide. The symptoms include shallow genital ulcers with suppurative granulomatous inflammation and tender inguinal lymphadenopathy. Chancroids can be differentiated from syphilitic chancres based on their appearance. In contrast to painless chancres, chancroids are painful. Ureaplasma urealyticum, Ureaplasma parvum, and Mycoplasma hominis are considered symbiotic bacteria. Infections caused by these bacteria are usually not considered STIs and do not require treatment unless they are suspected of being associated with infertility. This article presents the 2023 Korean STI guidelines for non-gonococcal bacterial infections.

Optic neuritis secondary to syphilis.

Optic neuritis is a rare manifestation of syphilis, and the involvement of the central nervous system should be considered synonymous with neurosyphilis. This infectious disease, well known as the great imitator, can affect any structure and produce multiple clinical symptoms. Here, we report a case of a 62- year-old male patient who presented to our service with decreased vision and myodesopsias in right eye. The posterior segment showed a hyperemic nerve with peripapillary hemorrhages and retinal pigment epithellium hyperplasia. The patient was recently diagnosed with HIV. Serology for syphilis was positive with posterior decreased levels of nontreponemal test following treatment with ceftriaxone. Optic neuritis can occur at any stage of syphilis and must always be considered a differential diagnosis.

Sudden hearing loss secondary to syphilis.

BACKGROUND: Syphilis is a sexually transmitted disease caused by the spirochete Treponema pallidum, whose incidence has increased significantly in recent years. Some patients may develop sudden hearing loss (SHL) against the background of otosyphilis. OBJECTIVES: The objective of our study was to determine whether routine lues serology is useful in patients presenting with sudden hearing loss. METHODS: For this purpose, all cases of SHL treated in our hospital during a period of 6 years were propectively collected. The frequency of positivity for syphilis in these patients, the treatment received, and their evolution were determined. RESULTS: Of the total number of patients evaluated during that period, 71 underwent serological screening for syphilis, of whom 2 (2.8 %) presented positive screening antibodies. In one of them, the RPR was normal and had been treated with lues a few years before. After treatment there was no improvement. The other patient, diagnosed with otosyphilis with unconfirmed suspected neurological disease, showed normalization of hearing after specific treatment. CONCLUSIONS: Since it is a potentially curable disease, despite the low overall frequency of syphilis in patients with SHL it is advisable to perform serological screening for syphilis in high risk patients (e.g., incarceration, multiple recent sexual partners, men who have sex with men) or atypical clinical presentation (e.g., concurrent neuropathies).

Diagnostic and Therapeutic Approaches for a Diabetic Patient Presenting with Secondary Syphilis and Severe Odynophagia.

Syphilis, an infectious disease caused by the spirochete Treponema pallidum, represents a pervasive global epidemic. Secondary syphilis is typically marked by the emergence of highly contagious mucocutaneous manifestations, including non-pruritic rashes on the palms and soles of the feet, alopecia, mucous patches, and condyloma lata. Here, we report a rare case of a 30-year-old male with newly discovered type 2 diabetes mellitus who presented with severe odynophagia due to secondary syphilis, confirmed by both nontreponemal VDRL/RPR and treponemal TPHA tests. Following the administration of a single-dose intramuscular injection of benzathine penicillin G 2.4 million units, the symptoms gradually decreased, allowing the patient to regain his health.

Proctitis: An Approach to the Symptomatic Patient.

Proctitis is an inflammatory condition of the distal rectum that can be associated with common sexually transmitted infections (STIs), such as gonorrhea, chlamydia, and syphilis. For persons presenting with ulcerative findings on examination, in addition to syphilis, Mpox, lymphogranuloma venereum, and herpes simplex virus should be in the differential. Providers should also be aware that there are evolving data to support a role for Mycoplasma genitalium in proctitis. Performing a comprehensive history, clinical evaluation including anoscopy, and rectal nucleic amplification STI testing may be useful in identifying the cause of proctitis and targeting treatment.

Unilateral tonsillitis due to primary syphilis with gram-negative corkscrew-like spirochaetes confirmed by Gram stain of pus.

A man in his 40s presented with pharyngeal pain and right cervical lymphadenopathy that persisted for 1 month. His right tonsil was swollen and covered with exudate; however, a rapid streptococcal antigen test was negative. Rapid plasma reagin and Treponema pallidum antibody were positive. Gram staining of the pus confirmed the presence of gram-negative corkscrew-like spirochaetes. The patient had unprotected oral intercourse. He did not have any skin lesions. He was diagnosed with primary syphilis and treated with benzathine penicillin G. In adults, the differential diagnosis of tonsillitis should include sexually transmitted diseases. A rapid streptococcal antigen test is not sufficient for such a case; a syphilis test is necessary, and Gram staining, which is rapid and does not need any special equipment, can support the diagnosis.

Temporal Trends in Syphilis Incidence among Men with HIV in Busan, Korea, 2005-2022: A Retrospective Cohort Study.

We aimed to assess the temporal trends of incident syphilis and its associated risk factors among men with HIV (Human Immunodeficiency Virus) in Korea during the COVID-19 pandemic. We conducted a retrospective cohort study of men with HIV attending an HIV clinic in Korea between 2005 and 2022. Of 767 men with HIV, 499 were included and contributed 3220 person-years (PY) of the observation period. Eighty-two patients were diagnosed with incident syphilis, with an overall incidence of 2.55/100 PY (95% confidence interval [CI] 20.56-31.53). The incidence of syphilis per 100 PY gradually decreased from 2.43 (0.79-7.42) in 2005-2007 to 1.85 (1.08-3.17) in 2014-2016; however, it increased to 3.0 (1.99-4.53) in 2017-2019, and further to 3.33 (2.26-4.89) in 2020-2022. A multivariate analysis identified young age (≤30 years versus >50, adjusted HR 6.27, 95% CI 2.38-16.56, p < 0.001), treponemal test positive at baseline (2.33, 1.48-3.67, p < 0.001), men who have sex with men (2.36, 1.34-4.16, p = 0.003), and history of incarceration (2.62, 1.21-5.67, p = 0.015) as risk factors for incident syphilis. Recently, syphilis incidence in men with HIV has increased in Korea, especially in young patients and at-risk groups, highlighting the need for enhanced regular screening and targeted behavioral interventions among these populations.
