HSV-infection-related herpetic anogenital ulcer disease among PLWH in southeastern US: electronic medical record based analysis.

ObjectivesThe southeastern US is a domestic epicentre for incident HIV with high prevalence of herpes simplex virus (HSV) coinfection. We estimated the incidence rates (IR) of symptomatic herpetic anogenital ulcer disease (HAUD) and assessed its associations with demographic and clinical characteristics, specifically with immunological markers using median, nadir and trajectory CD4 counts. METHODS: Electronic medical records (EMR) of over 7000 people living with HIV (PLWH) attending one of the leading HIV clinics in the southeastern US between 2006 and 2018 were reviewed and analysed. IR of HSV-related HAUD were estimated per 10 000 person years. Joinpoint regressions were performed to examine temporal changes in the trends of IR. All IR and trends were stratified by gender and race. Six CD4 trajectory groups were constructed using the group-based trajectory modelling. Multivariable logistic models were conducted to assess the associations of CD4 counts (nadir, median CD4 and newly defined CD4 trajectory), separately with HAUD. RESULTS: Of the 4484 PLWH eligible individuals (3429 men, 1031 women and 24 transgender), we observed 425 patients with HSV-related HAUD. The mean log10viral load was higher in HAUD than HAUD-free groups, whereas the median nadir CD4 count (cells/uL) was higher in the non-cases than the case groups (p<0.05). HAUD were more frequent in women than men. Median CD4 (<200 cell/uL) was associated with HAUD (OR=2.1), but there were no significant associations with nadir CD4. Significant associations with declining and sustained low CD4 counts trajectory patterns were observed with HAUD. CONCLUSIONS: There were significant differences between men and women with incident HAUD among PLWH. EMR-based studies can provide innovative trajectory models that can potentially be helpful in guiding screening and clinical care of HAUD among high-risk PLWH.

Atypical presentation of herpes simplex (chronic hypertrophic herpes) in a patient with HIV infection.

A 46-year-old man with HIV infection and AIDS presented with a large perianal ulcerated vegetative lesion that developed over a 1-year period. He had a past history of recurrent genital herpes infection, treated successfully each time with acyclovir. The perianal lesion developed while he was taking prophylactic acyclovir. Clinically, there were features suspicious of a carcinoma and a biopsy was reported as showing dysplasia. Therefore, the lesion was resected in its entirety. Histologically, there were prominent pseudo-epitheliomatous hyperplasia and chronic ulceration associated with herpesvirus infection. There was no evidence of dysplasia or malignancy. It is important to be aware of chronic vegetant herpesvirus infection, as clinical appearances are unusual and some methods of identification, such as smears or biopsy, may not be sufficient for diagnosis. Viral culture or PCR may need to be performed for a definite diagnosis to alleviate prolonged discomfort and avoid unnecessary radical surgery.

Atypical presentation of herpes simplex virus in a patient with chronic lymphocytic leukemia.

Perianal infections caused by herpes simplex virus are common in immunocompromised patients. The cutaneous presentation in these patients is often atypical, overlaps with the clinical features of other diseases, poses a difficulty in diagnosis, and responds poorly to treatment. An immunocompromised patient with chronic lymphocytic leukemia, treated with oral corticosteroids, presented with chronic perianal ulcerations. This patient was referred for evaluation and treatment of "recalcitrant" pyoderma gangrenosum. Prompt diagnosis was possible when the clinical features were recognized and appropriate biopsy and cultures were obtained. We describe an atypical presentation of herpes simplex virus associated with both an endogenous and exogenous induced immunodeficiency, and stress the importance of routinely performing cultures on all perianal ulcerations and anal fissures to avoid the misdiagnosis, inappropriate treatment, and prolonged discomfort of these afflicted patients.

Recurrent disseminated herpes zoster and cytomegalic perianal ulcer: a case report and review of the literature.

We describe a patient with lymphocytic leukemia who developed multiple, disseminated, vesiculopustular eruptions in combination with perianal ulcer. Four years earlier, she had a herpes zoster (HZ) infection involving the ophthalmic division of her left trigeminal nerve with subsequent postherpetic neuralgia that was treated with steroids. After the studies, we concluded that the patient had a recurrent disseminated HZ infection and perianal ulcer caused by cytomegalovirus (CMV).

Case report: herpes meningitis complicating genital herpes presenting as anal fissure.

A 33-year-old woman presented with stabbing perianal pain and intermittent headache and photophobia. Examination revealed atypical multiple perianal fissures with non-specific neurological findings. Polymerase chain reaction of the perianal swab and cerebrospinal fluid examination confirmed the diagnosis of perianal herpes simplex type 2 ulcer with herpes meningitis. This report emphasizes the importance of performing further investigations on patients with atypical anal fissures with or without systemic symptoms and signs to avoid misdiagnosis, inappropriate treatment and prolonged discomfort.

Successful treatment of an aciclovir-resistant herpes simplex type 2 infection with cidofovir in an AIDS patient.

Management of the increasing frequency of aciclovir-resistant herpes simplex virus (HSV) infections among immunocompromised human immunodeficiency virus-infected people demands additional treatment options. We report the case of a 38-year-old patient with acquired immune deficiency syndrome who suffered from a perianal butterfly ulcer, which was HSV-2 positive by polymerase chain reaction (PCR) analysis. The ulcer appeared during treatment of a cytomegalovirus (CMV) pneumonitis with ganciclovir. Despite additional valaciclovir therapy the lesion gradually progressed in size. Investigations including histology, PCR analysis and in situ hybridization of a biopsy from the growing ulcer margin confirmed the presence of HSV-2 infection. Importantly, HSV isolates from this specimen were resistant to aciclovir. Based on a report about the successful treatment of aciclovir-resistant HSV infection with cidofovir, our patient received this drug intravenously at a dose of 5 mg kg-1 body weight once weekly for a total of 3 weeks. Concomitant oral probenecid and prehydration were administered to minimize nephrotoxicity. Within 30 days of treatment the ulcer had almost (> 95%) completely healed. We conclude that cidofovir is a potent antiviral drug with a potential usefulness in the treatment of aciclovir-resistant HSV-2 infection. It deserves further investigation in clinical trials.

Thalidomide treatment of mucosal ulcerations in HIV infection.

Pain relief and resolution of oral and perianal ulceration after treatment with thalidomide in a 14 year old girl with vertically acquired HIV infection is reported.

The diagnosis of anal ulcers in AIDS patients.

Recent reports have suggested that routine microscopic evaluation of anal ulcer tissue from AIDS patients is not the most accurate way to diagnose viral infection. This study was undertaken to determine if either viral culture (VC) or immunohistochemistry (IHC) can improve the diagnostic accuracy as compared with routine hematoxylin and eosin (H&E) staining. Specifically, we sought to identify inclusion bodies of cytomegalovirus (CMV) or herpes simplex virus (HSV) to assist in the diagnosis of CMV or HSV. All patients had clinical evidence of an anal ulcer or a nonhealing anal fissure. Duration of symptoms ranged from 1 week to 3 months with a mean of 6 weeks. All specimens were submitted for viral culture in addition to routine H&E staining; immunohistochemistry was also performed. Twenty-five paraffin-embedded anal ulcer biopsies from 23 male patients (age range 27-73; mean 37.4 years) with the diagnosis of AIDS or AIDS-related complex (ARC) were reviewed over a 4 year period (1988-1992). Routine H&E staining revealed 6 (22%) specimens with CMV inclusions. Four of these 6 reacted positively with IHC (67%) and one was positive on viral culture (17%). In the remaining 19 specimens that did not reveal infection with CMV (78%), IHC was positive in 2 patients (10%) and viral culture was positive in 1 patient (5%). Although HSV was not seen in any of the specimens on H&E staining, IHC was positive in one patient (3.5%) and viral culture reacted positively in 8 (29%) specimens. Thus IHC is a good confirmatory test for CMV inclusions and can be used to achieve a definitive diagnosis in equivocal cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Management of idiopathic ulcer of the anal canal by excision in HIV-positive patients.

PURPOSE: The aim of this article is to show our results from the surgical treatment of idiopathic anal ulcers. METHODS: We present 33 patients with acquired immunodeficiency syndrome and idiopathic perianal ulcers. They presented with anal pain that failed to improve with medical treatment. Evaluation under anesthesia typically showed an irregular ulcer in the anal canal and an intersphincteric abscess. Surgical treatment consisted of an incision around the ulcer, its excision including margins but not its base, and abscess drainage. RESULTS: All patients experienced significant immediate postoperative pain relief. Biopsies of the ulcer showed chronic inflammation, and no specific agents appeared in cultures. CONCLUSIONS: These lesions seem to have the same cryptogenic origin as perianal abscesses, and we recommend surgical treatment to provide symptom relief.
