Syphilitic hepatitis in HIV-infected patients: a report of 7 cases and review of the literature

"Syphilitic Hepatitis": A Comprehensive Review of Clinical Features, Diagnostic Approaches, and Management Considerations

Syphilitic hepatitis is a very rare presentation of syphilis infection, characterized by inflammation of the liver due to the invasion of hepatic tissue by the bacterium Treponema pallidum. This review article provides an in-depth analysis of the existing body of information pertaining to syphilitic hepatitis. The article primarily concentrates on key aspects such as the epidemiology, clinical manifestations, diagnostic methods, and therapeutic approaches associated with this condition. Despite its rarity, awareness of syphilitic hepatitis is vital for accurate diagnosis and appropriate intervention. The clinical presentations frequently exhibit similarities with many liver illnesses, hence presenting difficulties in making an accurate diagnosis. Common symptoms include fatigue, stomach pain, and jaundice. Diagnostic procedures encompass the use of serological assays, including rapid plasma reagin (RPR) and fluorescent treponemal antibody absorption (FTA-ABS), in conjunction with imaging modalities to evaluate hepatic engagement. The primary therapeutic approach is the prompt initiation of antibiotic therapy, with a particular emphasis on penicillin, to eradicate the causative bacterial infection and facilitate the restoration of liver function. Failure to swiftly manage this condition may result in substantial morbidity. In summary, syphilitic hepatitis is a very uncommon but medically relevant manifestation of syphilis infection. The significance of increased clinical suspicion, precise diagnostic techniques, and prompt antibiotic administration is emphasized in this review since these are crucial in reducing the potentially severe outcomes associated with this illness.

The Great Imitator Masquerading as Autoimmune Hepatitis and Demystifying as Fulminant Syphilitic Retinitis

PURPOSE

Syphilis is a "Great Masquerader" because of its versatile clinical manifestations. We aim to report a patient whose first presentation was with presumed autoimmune hepatitis. Fulminant retinitis subsequently ensued, thus enabling correct diagnosis and treatment.

METHODS

Case description.

RESULTS

A 62-year-old male presented with bilateral drop in vision. One month earlier, right eye (RE) arteritic ischemic optic neuropathy was suspected because of severe headache, sudden drop in vision, relative afferent pupillary defect, and elevated inflammatory markers. Systemic steroids were instituted. Brain imaging and temporal artery biopsy were unyielding. Four months earlier, liver biopsy performed because of elevated cholestatic liver enzymes, revealed granulomatous hepatitis. After ruling out viral hepatitis, autoimmune etiology was presumed, and prednisone was started. On presentation, visual acuity (VA) was counting fingers in RE and 6/20 in the left eye (LE). Bilateral panuveitis with punctate inner retinitis, placoid chorioretinitis was diagnosed. Serological tests were strongly positive for syphilis. Lumbar puncture confirmed the existence of neurosyphilis. Systemic penicillin was initiated. One month later, VA improved to RE 6/10, LE 6/7.5, with marked resolution of posterior uveitis. No recurrence was observed over 27-month-period.

CONCLUSION

Acquired syphilitic hepatitis is rarely reported. Administering steroids potentially aggravated the infection. The characteristic features of placoid chorioretinitis and punctate inner retinitis connected the pieces of the puzzle together to the diagnosis of ocular and neurosyphilis. Intrahepatic cholestasis with negative serological panel of hepatotropic pathogens should raise the suspicion of non-hepatotropic pathogens especially syphilis.

Cholestatic Hepatitis with Concomitant Nephrotic Syndrome due to Secondary Syphilis in a Young Man

Introduction

Syphilis, an ancient sexually transmitted disease, is recognized as a systemic infection disease manifesting with diverse symptoms and variations. Secondary syphilis characterized by systemic symptoms resulted from hematogenous and lymphatic dissemination of the infection, may include manifestations such as hepatitis and nephrotic syndrome. However, the simultaneous occurrence of hepatitis and nephrotic syndrome in secondary syphilis is rare.

Case Presentation

A young man presented with fatigue, abnormal liver function tests, and hyperbilirubinemia and had history of men who have sex with men (MSM). Serological tests confirmed the diagnosis of secondary syphilis, and kidney biopsy indicated membranous nephritis. After antibiotic treatment, the patient experienced resolution of proteinuria, and liver enzyme levels returned to normal.

Conclusion

Syphilis should be considered in the differential diagnosis of simultaneous liver and kidney dysfunction, particularly in patients engaging in high-risk sexual behavior. This case highlights the importance of considering syphilis in young patients with MSM and presenting with unexplained nephrotic syndrome and liver abnormalities.

Intrahepatic cholestasis due to Treponema pallidum in an immunocompetent patient

Hepatitis due to Treponema pallidum is a rare entity and its diagnosis represents a clinical challenge. Treponema pallidum should be considered as a presumptive etiology in all patients with acute liver disease, when other frequent causes have been ruled out. We present the case of a young, immunocompetent patient with elevated values in his liver tests, a cholestatic pattern, and maculopapular lesions on his palms and soles. Given his clinical picture, diagnostic tests, and response to the antimicrobial therapy, a diagnosis of cholestasis due to secondary syphilis has been established. It is important to include secondary syphilis within the possible causes of acute liver disease.

Luetic (syphilitic) hepatitis: the great imitator persists in the 21st century

A male patient in his 20s was referred to the hepatology team with jaundice, pruritus and drenching night sweats. Investigations revealed an acute hepatitis with negative autoimmune and viral serology. Liver biopsy demonstrated severe pan-lobular hepatitis, and an extended diagnostic screen included a positive treponemal antibody test, with an RPR titre of 64, indicating active syphilis infection. He was treated with 2.4 million units of intramuscular benzathine penicillin as a single dose which led to complete resolution of the abnormal liver tests and symptoms. Diagnostic and management challenges, including the role of good history taking, appropriate investigations and role of multidisciplinary team, are discussed.

Cervical Syphilitic Lymphadenitis in a 29-Year-Old Female: A Case Report

Cervical lymphadenopathy is a common condition characterized by the enlargement of lymph nodes. It can have various causes, including infections, inflammatory conditions, and neoplastic processes. Syphilis, a sexually transmitted disease that progresses through multiple stages, can also be a rare cause of cervical lymphadenopathy, particularly in HIV-positive individuals. In this case report, we describe a patient presenting with throat pain, systemic symptoms, and cervical lymphadenopathy, initially clinically suggestive of lymphoma but ultimately determined to be caused by syphilis of unknown duration. This case highlights the importance of considering syphilis in the differential diagnosis of cervical lymphadenitis, particularly in patients with risk factors, such as intravenous drug use and HIV infection, and the need for a thorough evaluation of the patient's social and medical histories to diagnose and treat the condition accurately.

Syphilis

Syphilis is an important public health problem in the U.S. and many high-income nations. The rates of syphilis continue to increase and there is an urgent need for medical providers of a variety of backgrounds to recognize this disease. In this review, we cover the key clinical findings of syphilis and provide an overview of the diagnosis and management of this disease in adults.

Syphilitic Hepatitis: A Rare Cause of Elevated Liver Function Tests

Syphilitic hepatitis is a rare manifestation of syphilis with an incidence of 0.2-38%. We describe a case of a healthy, immunocompetent male patient with elevated liver function tests (LFTs) who was found to have syphilitic hepatitis. A 28-year-old male with no past medical history presented with abdominal pain for two to three weeks. He also reported diminished appetite, intermittent chills, weight loss, and fatigue. His history was positive for high-risk sexual behavior including multiple partners and absence of using protection. His physical examination was remarkable for right-sided abdominal tenderness and a painless chancre on his penile shaft. His workup revealed elevated aspartate aminotransferase (AST: 169 U/L), alanine transaminase (ALT: 271 U/L), and alkaline phosphatase (ALP: 377 U/L). His abdominal CT scan was unremarkable except for the abdominal and pelvic lymphadenopathy. A thorough serology panel revealed negative hepatitis A, B, C, human immunodeficiency virus (HIV) (including HIV RNA), Epstein-Barr virus (EBV), and cytomegalovirus (CMV). His immunological workup was negative as well. His rapid plasma reagin (RPR) was reactive with positive IgG/IgM treponemal antibodies. He was managed as secondary syphilis and received 2.4 million units of benzathine penicillin. Upon follow-up after one week, he reported a complete resolution of his symptoms, and his LFTs were normalized on a repeat checkup. Given the significant morbidity associated with a missed diagnosis, syphilitic hepatitis should be considered an essential part of the workup for evaluating elevated LFTs in an appropriate clinical setting. This case also highlights the importance of obtaining a comprehensive sexual history and performing a thorough genital examination.

Making a Comeback: Syphilitic Hepatitis in a Patient with Late Latent Syphilis-Case Report and Review of the Literature

Treponema pallidum infection has emerged in recent years as an important community threat and burden to the health care system. Here, we report the case of a patient with cholestatic liver disease secondary to late latent syphilis. A 41 year-old male patient was referred to the clinic for assessment of an abnormal liver function panel. Ultrasound of the abdomen demonstrated an intense liver echogenicity, normal bile ducts, and no ascites. Virologic study revealed negative results for antibodies against common viral hepatitis and metabolic and autoimmune disease. The patient was tested for syphilis and a positive result was reported. The patient was diagnosed with late latent syphilis and syphilitic hepatitis and initiated benzathine penicillin at G 7.2 million units total, delivered as three doses of 2.4 million units intramuscular each at one-week intervals. He was assessed monthly and by the end of the sixth month, he had nonreactive VDRL (seroconversion), which confirmed recovery. Syphilitic hepatitis is an overlooked type of hepatitis and should be kept in mind as a differential diagnosis in an abnormal liver panel of uncertain etiology. Health care providers should be advised that higher levels of ALP may be the single landmark in cases of syphilitic hepatitis.

Syphilis-Associated Proteinuria and Hepatitis in the Setting of Human Immunodeficiency Virus (HIV) Co-Infection

Syphilis has long been known as “the great imitator”, mimicking a wide variety of diseases, and often its diagnosis is delayed or missed. It remains an important public health issue that continues to occur at high rates among patients with HIV. We report a case of a 52-year-old man who presented with a constellation of unusual symptoms highlighting that syphilis should be included in the differential diagnosis in patients with HIV presenting with abnormal liver enzymes, rash, proteinuria, conjunctivitis, and/or sexual risk factors.

A Case of Syphilitic Hepatitis in an Adolescent

The incidence of syphilis is rising among adolescents necessitating improved provider awareness and screening practices. We present a case of an adolescent with acute hepatitis ultimately diagnosed with secondary syphilitic hepatitis. Clinical presentation, laboratory abnormalities, and histologic features of syphilitic hepatitis are nonspecific, with diagnosis relying on clinical suspicion and targeted testing. This case highlights the importance of screening for syphilis in sexually active adolescents with acute hepatitis. The rising incidence of syphilis among adolescents, and the variety of clinical manifestations including those commonly seen by pediatric gastroenterologists, makes elevated clinical suspicion essential to prompt diagnosis and treatment. With improved provider awareness across general pediatric and subspecialty providers, the transmission of syphilis among adolescent patients can be reduced.

Hepatic Secondary Syphilis Can Cause a Variety of Histologic Patterns and May Be Negative for Treponeme Immunohistochemistry

The rate of syphilis in the United States has been increasing steadily in the past decade, but it remains an uncommon diagnosis in tissue biopsies. Most of the pathology literature on hepatic syphilis consists of older series or case reports. This study aimed to systematically characterize the histologic spectrum of hepatic syphilis in a contemporary cohort. Clinicopathologic features of 14 hepatic syphilis cases between 2012 and 2018 were analyzed to characterize the broad spectrum of histologic changes. Thirteen patients were men (age range: 19 to 59 y); 6 had known human immunodeficiency virus, 7 were men known to have sex with men, and no patient had known prior syphilis. Hepatic syphilis was the primary clinical suspicion in only 1 patient. Common symptoms included jaundice, rash, and abdominal pain. Thirteen had elevated transaminases, and 12 had elevated alkaline phosphatase. Pathologic changes were grouped into 5 histologic patterns: biliary-pattern injury (n=5), acute hepatitis (n=4), autoimmune hepatitis-like (n=1), fibroinflammatory mass-forming lesion (n=2), and no particular pattern (n=2). Nearly all showed portal and lobular lymphocytes and plasma cells; 12 had prominent histiocytes/Kupffer cells, 9 had ductular reaction, and 7 had duct inflammation. Occasional focal findings included dropout (n=7), phlebitis (n=7), and loose granulomata (n=5). Treponeme immunohistochemistry was positive in 10 and negative in 4, though treatment was given before biopsy in 3 of those 4. Thirteen patients had rapid plasma reagin testing either before or after biopsy, with 1:64 or higher titer. All patients who received treatment recovered. Hepatic syphilis is rare but likely underrecognized. It exhibits a variety of histologic appearances and therefore should be considered in several hepatic differential diagnoses, especially in men who have sex with men. Kupffer cells, granulomata, and phlebitis may suggest the diagnosis regardless of predominant histologic pattern. Negative treponeme immunohistochemical staining does not exclude the diagnosis, including in untreated patients.

When the Sailor’s Handshake Fails: A Case of Syphilitic Hepatitis in an HIV Patient With Nonspecific Liver Biopsy and Atypical Cutaneous Presentation

Secondary syphilis has variable systemic manifestations, impersonating the presentation of more common pathologies, deceiving clinicians, and creating a difficult-to-diagnose patient. The case discussed combines hepatic syphilis with an uncommon syphilitic dermatologic presentation in a patient with HIV and a history of hepatitis A and B. Due to the challenge of diagnosis, the relative ease of confirming the diagnosis with serological assays, and reversibility of hepatic injury, the inclusion of syphilitic hepatitis on a differential diagnosis of hepatitis is warranted.

Chronic pain and infection: mechanisms, causes, conditions, treatments, and controversies

Throughout human history, infection has been the leading cause of morbidity and mortality, with pain being one of the cardinal warning signs. However, in a substantial percentage of cases, pain can persist after resolution of acute illness, manifesting as neuropathic, nociplastic (eg, fibromyalgia, irritable bowel syndrome), or nociceptive pain. Mechanisms by which acute infectious pain becomes chronic are variable and can include immunological phenomena (eg, bystander activation, molecular mimicry), direct microbe invasion, central sensitization from physical or psychological triggers, and complications from treatment. Microbes resulting in a high incidence of chronic pain include bacteria such as the Borrelia species and Mycobacterium leprae, as well as viruses such as HIV, SARS-CoV-2 and herpeses. Emerging evidence also supports an infectious cause in a subset of patients with discogenic low back pain and inflammatory bowel disease. Although antimicrobial treatment might have a role in treating chronic pain states that involve active infectious inflammatory processes, their use in chronic pain conditions resulting from autoimmune mechanisms, central sensitization and irrevocable tissue (eg, arthropathy, vasculitis) or nerve injury, are likely to cause more harm than benefit. This review focuses on the relation between infection and chronic pain, with an emphasis on common viral and bacterial causes.

Case Report: Syphilitic Hepatitis-A Rare and Underrecognized Etiology of Liver Disease With Potential for Misdiagnosis

Syphilitic hepatitis (SH) in adults is a rare condition that can be easily misdiagnosed. Clinical and histopathologic manifestations of SH can mimic other infectious and non-infectious conditions, and the diagnosis should be considered in all at-risk patients with abnormal liver function tests. We present an unusual case of SH presenting with seizures and multiple liver lesions. This case report, in line with other newly published reports, promotes awareness of SH as a rare manifestation of treponemal infection and highlights the importance of including SH in the differential diagnosis for patients at risk for sexually transmitted infections and presenting with liver enzyme abnormalities. From a hospital quality control and socioeconomic perspective, our case adds to the growing body of evidence that demonstrates an increasing incidence of patients suffering from venereal diseases and injection drug use disorders, and the burden these conditions place on the healthcare system. Recognition of the clinicopathologic features of SH is required to prevent missed diagnosis and to foster systematic crosstalk between healthcare staff and public health personnel managing this problem.

An analysis of the clinical features of children with early congenital Syphilis and Syphilitic Hepatitis

Background

The infection rate of congenital syphilis is gradually increasing, the clinical manifestations of some children with congenital syphilis are abnormal liver function, which is given the clinical diagnosis of syphilitic hepatitis. At present, there are few studies on the clinical features of children with early congenital syphilis combined with syphilitic hepatitis, so we set out to do such a study. We compared the liver function indicators before and after the treatment of syphilis to find the clinical features that can provide guidance for clinical diagnosis and treatment.

Methods

This study collected clinical data on 51 children with early congenital syphilis combined with syphilitic hepatitis in Beijing Ditan Hospital, affiliated with Capital Medical University, between April 2014 and October 2019. We observed their age, gender, clinical symptoms, and physical symptoms, as well as the pregnancy and childbirth history of their mothers. We also compared the liver function indicators before and after the treatment of the syphilis and analyzed the children’s clinical features.

Results

The results of this study showed that the clinical manifestations in children with early congenital syphilis combined with syphilitic hepatitis were diverse. The most common clinical manifestation was anemia (56.9 %), followed by syphilitic rash (54.9 %), hands, feet, and whole-body peeling (35.3 %), and splenomegaly (29.4 %). Liver damage caused by a syphilis infection tends to result in elevated alanine aminotransferase, aspartate aminotransferase, and bilirubin, while albumin decreases. After the syphilis treatment, the liver function indexes were significantly improved compared with before treatment, and the difference was statistically significant (all p < 0.05).

Conclusions

A child with abnormal liver function, especially with anemia, skin rash, peeling, abdominal distension, and hepatosplenomegaly should be highly suspected of having a syphilis infection. Once the diagnosis is made, the appropriate standard penicillin treatment should be started as soon as possible to improve the condition and prognosis of the child.

Syphilitic hepatitis as a manifestation of secondary syphilis

Syphilis is a multisystem disease caused by the spirochete Treponema pallidum. Among various organs affected, liver involvement is seen infrequently and can be missed. Here we present a case of hepatitis due to secondary syphilis that completely resolved with penicillin G therapy.

An Unusual Case of Syphilis With Abdominal Pain

Syphilis is a multisystem infection caused by Treponema pallidum, a common sexually transmitted bacterium. The different stages and associated signs of syphilis are well characterized. We present an atypical case of syphilis in a 27-year-old female with hepatitis and gastritis. The diagnostic criteria for syphilitic hepatitis and gastritis are discussed here, along with endoscopic and clinical findings, treatment, and a brief literature review.

A great mimicker of primary biliary cholangitis

A 59 year-old man without past medical history was referred with biochemical features of cholestasis (aspartate aminotransferase (AST) 117 U/L, alanine aminotransferase (ALT) 83 U/L, gamma-glutamyl transferase (GGT) 1307 U/L, alkaline phosphatase (AP) 1803 U/L, total bilirubin 0,7 mg/dL), a strongly positive antimitochondrial M2 antibody (AMA-M2) titer (88 U), weight loss and abdominal pain since several months. He did not take any medications, nor there was a history of alcohol abuse or sexual risk behavior. Upon presentation, clinical examination showed a rather cachectic patient (body mass index 19 kg/m²), without further abnormalities. As primary biliary cholangitis (PBC) was suspected, treatment with ursodeoxycholic acid had been initiated but did not improve the cholestasis nor the pain. Additional investigations didn’t reveal any other irregularities, except for a mildly dilated aortic sinus root of 42 mm. The histopathological findings of a liver biopsy are shown below (Figure 1). This showed granulomas with cholangitis and increased presence of neutrophils, which raised suspicion for an infectious cause.

Exploring the Ways of “The Great Imitator”: A Case Report of Syphilitic Hepatitis

Introduction

Syphilis is a chronic infection caused by Treponema pallidum. Manifestations of this disease are vast, and syphilitic hepatitis is a rarely depicted form of secondary syphilis.

Case Presentation

We report the case of a 63-year-old man with worsening jaundice, maculopapular rash and perianal discomfort. Proctological examination with anoscopy revealed a perianal gray/white area with millimetric pale granules along the anal canal. Liver function tests showed a mixed pattern. Venereal Disease Research Laboratory, T. pallidum hemagglutination assay and IgM fluorescent treponemal antibody absorbance were positive. The patient was successfully treated with a single dose of penicillin G.

Discussion/Conclusion

Syphilitic hepatitis is scarcely reported in the literature. Secondary syphilis with mild hepatitis rarely leads to hepatic cytolysis and jaundice. Many signs of secondary syphilis including syphilitic hepatitis may be linked to immune responses initiated during early infection. Over the past decades, evidence has emerged on the importance of innate and adaptive cellular immune responses in the immunopathogenesis of syphilis. This report raises awareness to a clinical entity that should be considered in patients at risk for sexually transmitted diseases, who present with intestinal discomfort or liver dysfunction, as it is a treatable and fully reversible condition.

Syphilitic Hepatitis: A Rare Cause of Acute Liver Injury

Syphilitic hepatitis represents a rare manifestation of treponemal infection. Diagnosis is achieved with the presence of characteristic syphilitic signs and symptoms along with positive serological markers, characteristic elevated liver enzymes, and no other alternative cause of hepatobiliary insult. Here we detail a case of a patient presenting with recently diagnosed secondary syphilis causing abnormal liver enzymes. With the increasing incidence of venereal diseases in the United States, this case highlights the importance of identifying syphilis as a differential diagnosis for acute liver injury.

Syphilis Hepatitis Presenting as a Mimic of Primary Biliary Cholangitis

Syphilis hepatitis is a rare cause of acute liver injury. Primary biliary cholangitis (PBC) is a progressive autoimmune disease characterized by the typical presentation of a cholestatic liver injury and the presence of antimitochondrial antibodies (AMAs). We present a case of syphilis hepatitis that presented as a mimic to PBC with positive AMA. The eradication of syphilis led to the resolution of the liver injury and down trending of the antibody level. We recommend excluding syphilis in patients with high-risk behaviors presenting with a cholestatic liver injury and positive AMA before the diagnosis of PBC.

The Great Spiral Masquerader: A Case of Concurrent Secondary Syphilis and Autoimmune Hepatitis

We describe a unique case of rash and acute hepatitis confounded by the presence of syphilis that created suspicion for syphilitic hepatitis, a rare and often misdiagnosed condition. Investigation concerning the etiology alternatively lead to the diagnosis of 2 concomitant conditions: active autoimmune hepatitis and secondary syphilis. To our knowledge, this is the first description in the literature of the simultaneous occurrence of secondary syphilis and autoimmune hepatitis. This case serves to increase the recognition of the clinical characteristics and diagnostic challenges of syphilitic hepatitis and to discuss the potential role of pathogens in the induction of autoimmunity.

Prevalence of Syphilitic Hepatitis Among HIV-Infected Patients in Istanbul, Turkey, a Region with an Increasing Incidence of Syphilis and HIV Infection

Background: Syphilis is a global health issue, which continues to occur at high rates worldwide, particularly in HIV-infected men, who have sex with men (MSM). Hepatitis can present as an uncommon manifestation of syphilis, and the diagnosis may be overlooked in favor of more common causes of liver injury in this group. Objectives: This study aimed to determine the prevalence and risk factors of syphilitic hepatitis among HIV-infected individuals diagnosed with acute syphilis. Methods: This cross-sectional study was conducted on HIV-infected individuals who regularly attended a tertiary clinic in Istanbul. The data were collected and analyzed between 2016 and 2019. Cases of syphilitic hepatitis were included according to the following criteria: (I) VDRL-confirmed Treponema pallidum infection after or simultaneously diagnosed with HIV infection; (II) elevated liver enzymes, including ALT, AST, and ALP, that resolved after penicillin treatment; and (III) exclusion of other causes of hepatitis. Sociodemographic characteristics of the participants, clinical and laboratory findings were evaluated using medical records. Results: Among 1,057 HIV-infected patients, 141 (13.3%) were diagnosed to have an early stage of syphilis, 138 of them were male. Nine (6.4 %) out of 141 patients had syphilitic hepatitis, and all of them were self-identified MSM. Moreover, 5 out of these 9 patients were simultaneously diagnosed with syphilis and HIV infection. Up to 10-fold increase in ALT/AST was noted in all of them, and a 3.5-fold increase in bilirubin was observed in two cases. The most prominent laboratory abnormalities in syphilitic hepatitis patients were the detection of a considerable increase in ALP and HIV RNA levels. Conclusions: Syphilitic hepatitis is not encountered rarely in HIV-infected individuals, predominantly MSM populations. Since HIV/syphilis coinfected patients are more infective as a result of higher HIV RNA levels, early diagnosis, and treatment are crucial.

Syphilis-Associated Acute Renal Failure and Hepatitis in the Setting of Human Immunodeficiency Virus Coinfection

Two individuals with human immunodeficiency virus presented in acute renal failure with nephrotic range proteinuria and were diagnosed with secondary syphilis. One of them also had elevated transaminases. Kidney biopsies revealed membranous nephropathy, a rare complication of secondary syphilis, in both cases. Normal hepatic and renal function were restored after treatment with penicillin.

Spirochetes in the Liver: An Unusual Presentation of a Common STI

It is estimated that 10% of patients with secondary syphilis have liver enzyme elevations, but clinical hepatitis is rare. However, in HIV-positive patients, syphilitic hepatitis may be much more common. We report a case of a 67-year-old male who developed progressively elevated liver enzymes, followed by development of neurological symptoms and then rash. Though the timeline of his symptom development was unusual, his constellation of symptoms prompted an RPR and FTA-ABS which returned reactive. He was additionally found to be HIV positive with a CD4 count of 946. He was treated with IV Penicillin, and his hepatitis improved thereafter.

Syphilitic hepatitis: a case report and review of the literature

Background

Syphilis is a common disease that has been researched and focused on for many years, however, syphilitic hepatitis has not been well-recognized. We report this case of syphilitic hepatitis with intrahepatic cholestasis and liver granulomas to make a deeper impression.

Case presentation

A 47-year-old male was admitted with jaundice and rashes. The laboratory examination showed abnormal liver enzymes with significant increases in ALP and GGT but mild increases in ALT and AST. His HBV surface antigen was weakly positive, with negative HIV antibody, HCV antibody, and undetectable HBV DNA. The rapid plasma reagin test and the Treponema pallidum particle assay tests for Syphilis were both positive. Abdominal ultrasonography and magnetic resonance cholangiopancreatography revealed the normal biliary tract, liver, and spleen. The liver pathological examination showed cholangiocyte inflammation and micro-granulomas with coagulation necrosis. After 2 months of benzathine penicillin treatment, his liver enzyme decreased rapidly and remained normal after 1-year of follow-up.

Conclusions

Increased liver enzymes, intrahepatic cholestasis and liver granulomas with well-response to antibiotics may provide clues for the diagnosis of syphilitic hepatitis.

Syphilis, The Great Mimicker, Presents As a Rare Case of Concurrent Hepatitis and Gastroparesis

Syphilis has been called “the great mimicker” given its ability to affect a wide variety of organs and subsequently present with a vast array of symptoms. The variability in clinical presentation seen in syphilis can make the diagnosis challenging. We describe a unique presentation of syphilis manifesting as hepatitis and gastroparesis. To our knowledge, this is the first case report with simultaneous hepatic and gastric involvement.

Hepatitis in patients with syphilis: an overlooked association

We present the case of a patient who sought treatment for fever and a maculopapular rash involving the trunk, limbs, palms and soles. The patient also presented with hepatomegaly and elevated levels of liver enzymes (with a higher increase of alkaline phosphatase). With the proposal of early syphilitic hepatitis, during the stage of secondary syphilis, a venereal disease research laboratory and Treponema pallidum haemagglutination tests were requested, which confirmed the diagnosis. All altered parameters improved with antibiotic treatment for secondary syphilis. Syphilitic hepatitis is an often overlooked presentation of syphilis and should be considered as a differential diagnosis in patients with elevated levels of liver enzymes and risk factors for syphilis.

Liver Cholestasis Secondary to Syphilis in an Immunocompetent Patient

Liver involvement is a known feature of secondary syphilis. The prevalence of hepatitis in secondary syphilis ranges broadly from 1 to 50%. We report a case of a 37-year-old man with type 1 diabetes mellitus and sickle cell trait presenting with jaundice and acute liver cholestasis. Abdominal ultrasound revealed mild hepatic fatty infiltration. RPR and Treponema pallidum IgG results were positive with a reflex titer of 1:64. Liver biopsy revealed chronic hepatitis with normal hepatic architecture, Kupffer cell hyperplasia, hepatic cholestasis, and ductal proliferation suggestive of syphilitic hepatitis.

A Systematic Literature Review of Syphilitic Hepatitis in Adults

Syphilitic hepatitis in adults is not frequently found in the population and is easily misdiagnosed. The incidence of viral hepatitis is increasing year by year, concomitantly increasing the importance of obtaining a systematic understanding of the clinical features and treatment strategies for this disease. There is, however, a lack of published definitive data regarding the clinical characteristics, diagnosis and standard treatment options for this disease. Searches were made using the MEDLINE database of PubMed and OVID for syphilitic hepatitis publications from 1951 to 2017 in an attempt to analyze and summarize the clinical characteristics.

Secondary Syphilis Associated with Membranous Nephropathy and Acute Hepatitis in a Patient with HIV: A Case Report

INTRODUCTION

We present a case of membranous nephropathy associated with a secondary syphilis infection in a patient with HIV.

CASE PRESENTATION

A 37-year-old white man with HIV who was receiving highly active antiretroviral therapy presented to the Emergency Department with 6 weeks of rectal pain. He had a CD3-CD4 count of 656 cells/mm³ and an undetectable viral load. On admission, he was found to have an anal ulcer, a serum creatinine of 1.4 mg/dL (baseline 0.7 to 1.0 mg/dL), elevated transaminases, positive rapid plasmin reagin, and a urine protein/creatinine ratio revealing nephrotic-range proteinuria. Renal biopsy demonstrated membranous nephropathy with features suggestive of a secondary cause. Our patient was treated with penicillin for secondary syphilis, with normalization of renal function, resolution of the nephrotic syndrome, and improvement of his elevated transaminases.

DISCUSSION

This case is a reminder that patients with HIV are not infrequently coinfected with Treponema pallidum and that secondary syphilis can have systemic manifestations, including elevated transaminases and nephrotic syndrome. Prompt diagnosis and treatment will result in resolution of these problems.

A case of syphilitic hepatitis in an HIV-infected patient

While the incidence of syphilis has been persistently on the rise in the United States, hepatitis as a complication of early syphilis is relatively uncommon. We present a case of a 51-year-old homosexual, HIV-positive man who presented with acute cholestatic hepatitis with a predominantly elevated alkaline phosphatase. After laboratory studies and imaging were unrevealing, a liver biopsy was performed that showed expanded portal tracts with a predominantly lymphoplasmacytic infiltrate and prominent bile ductular proliferation with periductal neutrophils. Testing revealed a positive rapid plasma reagin, and a subsequent Warthin-Starry stain of the liver tissue demonstrated the presence of scattered spirochetes, confirmed as Treponema pallidum spirochetes on immunohistochemistry testing. These findings confirmed a diagnosis of syphilitic hepatitis. With therapy, symptoms and liver enzymes rapidly normalized. Given the persistent rise in syphilis incidence along with the morbidity and mortality associated with a missed diagnosis, keen suspicion, early identification, and treatment are crucial.

Presentaciones poco comunes y peligros de la sífilis secundaria: periosteitis, tenosinovitis y anomalías hepáticas

We herein describe two cases of secondary syphilis in patients with human immunodeficiency virus (HIV) infection with an unusual presentation, a diffuse polyostotic periosteitis. Patients referred mainly intense bone pain. Other relevant aspects of the clinical pictures were flexor tenosynovitis and hepatic abnormalities. Given the persistence of symptoms, the treatment duration performed was different from most described in literature. However, although more slowly than expected, both obtained a favorable clinical response after treatment with benzathine penicillin G.

The Great Impostor: Transaminitis Masking the Coinfection of Syphilis and Human Immunodeficiency Virus

Introduction. The incidence of syphilis continues to rise in the United States over the past 15 years. This disease process is classified into stages and may present with a coinfection of Human Immunodeficiency Virus (HIV). Case Report. We present a case of a 32-year-old African American male who presented with cutaneous manifestations of secondary syphilis and transaminitis. A workup revealed that the transaminitis was secondary to underlying syphilitic hepatitis in the presence of HIV coinfection. The patient had a reactive rapid plasma reagin (RPR) of 1 : 64 TU and reactive Treponema pallidum particle agglutination assay (TPPA). Lab findings showed alkaline phosphate (ALP) of 648 unit/L, aspartate aminotransferase (AST) of 251 unit/L, and alanine aminotransferase (ALT) of 409 unit/L. Conclusion. Syphilitic hepatitis is a recognized entity in the medical literature. It is a manifestation of secondary syphilis and it is more commonly seen in coinfected patients with both syphilis and HIV. Therefore, primary care physicians should keep infectious etiologies (e.g., syphilis and HIV) in the differential diagnosis of patients who present with unexplained liver dysfunction in a cholestatic pattern.

The Great Pretender: early syphilis mimicking acute sclerosing cholangitis

A 36-year old man with known HIV infection presented to an outpatient genitourinary service with jaundice, rash and sore throat. Investigations revealed marked biochemical abnormalities, including alkaline phosphatase and alanine transaminase >10 times the upper limit of normal. Liver ultrasound was normal, but stricturing and beading of the intrahepatic biliary tree was seen on magnetic resonance cholangiopancreatography (MRCP), similar to changes associated with sclerosing cholangitis. Serological syphilis antibodies were detected with a positive immunoglobulin M (IgM) and rapid plasma reagin of 1:128, in keeping with early infection. Liver biopsy showed large bile duct obstruction with portal oedema, bilirubinostasis and neutrophil polymorph infiltration around proliferating ductules; specific stains for spirochaetes were negative. Symptoms and biochemical markers improved rapidly after treatment for secondary syphilis with oral steroids and intramuscular benzathine penicillin. A repeat MRCP 18 months post syphilis treatment showed resolution. This case illustrates syphilis presenting as acute sclerosing cholangitis.

Syphilitic hepatitis treated with doxycycline in an HIV-infected patient and review of the literature

An HIV-infected male patient who had sex with men and with a penicillin allergy presented with liver dysfunction due to secondary syphilis and was successfully treated with doxycycline. This case highlights that syphilitic hepatitis may be overlooked in this particular population, and health care providers should be attuned to this diagnosis. Doxycycline may be an acceptable alternative to penicillin for treatment of this clinical syndrome.

Syphilis presenting as inflammatory tumors of the liver in HIV-positive homosexual men

Syphilis, a sexually transmitted infection caused by the spirochete Treponema pallidum, has seen a resurgence since 2001, particularly in men who have sex with men. Syphilis can affect the liver during the secondary stage as syphilitic hepatitis and during the tertiary stage as gummas. We describe 3 cases of syphilis in human immunodeficiency virus-positive homosexual men that presented as hepatic mass lesions clinically suspected of being malignant tumors. Histologically, 2 of the 3 cases showed a plump spindle cell proliferation, mixed inflammatory infiltrate with numerous neutrophils, and abscesses, whereas the third case showed granulomas and pericholangitis/cholangitis. Immunohistochemical staining for T. pallidum showed innumerable organisms in 2 of the cases. Pathologists must be aware of the possibility of syphilis causing hepatic inflammatory masses in human immunodeficiency virus-positive men who have sex with men in order to avoid misdiagnosis or delayed treatment.
