A case of syphilitic hepatitis in an HIV-infected patient

Acute hepatitis as a manifestation of secondary syphilis: a case report and literature review

This is the case of a 25-year-old patient, with the notion of unprotected sexual relations with multiple partners consulted for cholestatic icterus with pruritus evolving for 2 months. The general examination found an intense mucocutaneous icterus. The examination of the lymph nodes revealed multiple lymph nodes. A thoracic-abdominal-pelvic scanner showed peri-portal edema and adenopathies above and below the diaphragm without suspicious lesions. Biologically, there was acute cytolysis with ASAT at 1612IU/L, ALAT at 1506IU/L, and icteric cholestasis, the acute viral serologies and other autoantibodies were all negative. Given the presence of adenopathy and sexual risk factors, a syphilis serology was requested and was positive: a TPHA at 2560UI/L, and a VDRL at 1/32 UI/L. A liver biopsy was performed, which showed the presence, on immunohistochemistry, of anti-treponemal-pallidum antibodies. After eliminating all etiologies of cytolytic hepatitis, we retained the diagnosis of syphilitic hepatitis. Therapeutically, we started a treatment based on ceftriaxone 2g/dl with spectacular biological improvement at H48 of the beginning of treatment.

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.

Acute Liver Injury as a Manifestation of Secondary Syphilis

In the United States, the incidence of new cases of syphilis has been rising. The number of cases of primary and secondary syphilis has continued to increase almost every year over the past 2 decades. Secondary syphilis has a variety of clinical manifestations. A frequently overlooked presentation is that of syphilitic hepatitis, which should be part of the differential diagnosis for patients with elevated liver enzymes, a maculopapular rash, and/or risk factors for contracting syphilis. In this study, we report a rare and unusual case of a man with a remote history of syphilis infection who developed 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.

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.

Syphilitic hepatitis: Case report of an overlooked condition

Syphilis is an overlooked cause of hepatitis. Syphilitic hepatitis should be a differential diagnosis in all patients with abnormal liver biochemical marker levels. Syphilitic hepatitis has been defined as the combination of increased liver enzymes, positive serology for syphilis, the absence of alternative causes for hepatobiliary injury, and liver enzyme improvement with proper antibiotic therapy.

Fulminant hepatitis in a patient with secondary syphilis

Despite the increasing incidence of syphilis and due to its wide variety of clinical manifestations, syphilis remains an under-diagnosed condition. We report an unusual case of secondary syphilis presenting with acute hepatitis and skin lesions, confirmed based on positive treponemal and non-treponemal assays. Despite adequate diagnosis and treatment, the patient developed fulminant hepatitis and brain death. This atypical presentation emphasizes the importance of high clinical suspicion in recognizing syphilis as an etiology for unexplained acute hepatitis, allowing early diagnosis and treatment and possibly avoiding severe complications such as fulminant hepatic failure.
