Diagnosis and treatment of a case of cutaneous cytomegalovirus infection with a dramatic clinical presentation

Qualitative evaluation of connective tissue disease with cytomegalovirus infection: A meta-analysis of case reports

BACKGROUND

The primary therapies for connective tissue disease include glucocorticoids and immunosuppressants. However, their prolonged usage can precipitate opportunistic infections, such as cytomegalovirus infection. When managing connective tissue disease complicated by cytomegalovirus infection, judicious selection of treatment modalities is crucial. This involves assessing the necessity for antiviral therapy and contemplating the reduction or cessation of glucocorticoids and immunosuppressants.

OBJECTIVE

This investigation sought to methodically review existing literature regarding treating connective tissue disease patients with cytomegalovirus infection.

METHODS

On July 5, 2023, an exhaustive literature search was conducted. Data analysis utilized the Kruskal-Wallis test or one-way analysis of variance, supplemented by Bonferroni post hoc testing.

RESULTS

Our meta-analysis incorporated 88 studies encompassing 146 connective tissue disease patients with CMV infections. The results indicated that patients with connective tissue disease and cytomegalovirus disease benefitted more from antiviral therapy than those not receiving such treatment (P = 0.003, P < 0.005). Furthermore, the strategic reduction of glucocorticoids and/or immunosuppressants was beneficial (P = 0.037, P < 0.05). Poor clinical outcomes with glucocorticoid-immunosuppressant combination therapy compared to other treatment modalities. The findings also suggested that CMV infection patients fare better without Cyclosporine A than using it (P = 0.041, P < 0.05).

CONCLUSION

Antiviral therapy is a viable treatment option in cases of connective tissue disease co-occurring with cytomegalovirus disease. Additionally, when connective tissue disease is stable, there is potential merit in reducing glucocorticoids and/or immunosuppressants, especially avoiding the combination of these drugs. For all cytomegalovirus infection patients, Cyclosporine A may be avoided wherever possible for selecting immunosuppressive agents if its use is not deemed essential in the treatment regimen.

Cytomegalovirus-induced oral ulcers: A case report and literature review

Cytomegalovirus (CMV) ulcerations are rare clinical entities, but their occurrence is favored in immunocompromised patients who present a favorable environment for opportunistic infections. We describe the case of a patient treated for a systemic lupus erythematosus suffering from deep oral ulcerations. The case illustrates the complexity of establishing a precise etiological diagnosis of CMV lesions, as the diagnostic hypothesis can be varied: related to an immunodeficiency disorder or drug-induced toxidermia.

Cytomegalovirus-induced cutaneous ulcer mimicking vasculitis in a patient with systemic lupus erythematous: A case report and review of the literature

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease which can be complicated with cytomegalovirus (CMV) infection during its course. CMV reactivation can mimic an SLE flare and lead to delay in diagnosis. Here, we reported a previously diagnosed SLE patient who presented with fever, leukopenia, and cutaneous ulcers. Initially, this was diagnosed as an SLE flare and the patient was treated with higher doses of corticosteroids but no improvement was observed. Both nuclear and cytoplasmic inclusions inside the endothelial cells in the skin biopsy as well as positive immunohistochemistry (IHC) staining for CMV antigen were clues to the correct diagnosis of CMV reactivation. Treatment with ganciclovir resulted in clinical resolution. In this report, a very rare clinical form of CMV infection manifesting as cutaneous necrotizing vasculitis on the lower extremity is described and the literature regarding this case is reviewed.

Unusual Manifestations of Acute Cytomegalovirus Infection in Solid Organ Transplant Hosts: A Report of Two Cases

Cytomegalovirus (CMV) infection is a common cause of morbidity and mortality in immunocompromised hosts. Tissue-invasive CMV disease causing ulcerative skin disease or esophageal necrosis is rare. We herein describe two cases: a 47-year-old renal and pancreas transplant recipient who presented with skin ulcerations on his elbow and a 50-year-old renal transplant recipient who presented with acute esophageal necrosis. In both, tissue biopsy revealed CMV inclusion bodies by immunohistochemical staining of infected endothelial and mucosal cells. Ganciclovir was given to both cases and full remission occurred. Due to the varying presentations of acute CMV infection in immunosuppressed hosts, high suspicion and early tissue biopsy are vital for proper diagnosis and treatment when any suspicious cutaneous or mucosal manifestations are present.

Cytomegalovirus-induced cutaneous microangiopathy manifesting as lower limb ischemia in a human immunodeficiency virus-infected patient

Cutaneous infections by cytomegalovirus (CMV) are rare and often difficult to diagnose both clinically and histopathologically. A wide range of different clinical manifestations have been described in the literature, especially in immunosuppressed patients. CMV-induced thrombosis has also been reported in these patients, and various mechanisms have been proposed to explain the role of CMV in the thrombotic process, including direct damage of the endothelial cells, activation of coagulation factors and inducing the production of antiphospholipid antibodies. We present the case of a human immunodeficiency virus (HIV)-infected woman who developed distal ischemic lesions of the lower extremities during a generalized CMV infection. We discuss the role of CMV and antiphospholipid antibodies in the pathogenesis of thrombosis in immunosuppressed patients.

Fatal cytomegalovirus infection in two patients with systemic lupus erythematosus undergoing intensive immunosuppressive therapy: role for cytomegalovirus vigilance and prophylaxis?

Cytomegalovirus (CMV) infection is an uncommon but potentially fatal opportunistic infection in patients with systemic lupus erythematosus (SLE). We report 2 patients with severe SLE with life-threatening, multisystemic involvement who were treated with intensive immunosuppressive therapy. SLE was successfully controlled, but the patients succumbed to fatal reactivation of CMV disease despite antiviral therapy. Both were seropositive for CMV. We therefore advocate that there should be more active CMV vigilance, and polymerase chain reaction (PCR)-based CMV prophylaxis should be considered in CMV PCR-positive patients with SLE/rheumatic disease undergoing intensive immunosuppressive therapy.

Characteristics of cutaneous cytomegalovirus infection in non-acquired immune deficiency syndrome, immunocompromised patients

BACKGROUND

Although cytomegalovirus (CMV) disease is a severe complication among immunocompromised patients, its cutaneous features have not been frequently reported. As herpes simple virus (HSV) infection commonly develops in CMV skin lesions, a study is needed on the pathogenetic role of CMV in cutaneous lesion formation.

OBJECTIVES

The purpose of this study is to characterize the clinical and histopathological features of cutaneous CMV infection and to determine whether CMV plays a true pathogenetic role in cutaneous lesions, or if it is just an innocent bystander during HSV infection among non-AIDS (acquired immune deficiency syndrome), immunocompromised patients.

PATIENTS AND METHODS

A total of nine human immunodeficiency virus-negative patients diagnosed with cutaneous CMV infection from July 1999 to February 2005 at Samsung Medical Center were analysed in terms of their clinical and histopathological characteristics. In addition, we examined for the co-presence of HSV by performing immunohistochemical analysis and polymerase chain reaction.

RESULTS

All the patients were immunocompromised; five had haematological diseases and four were organ transplant recipients. The clinical and histopathological features were similar to those of previous studies of patients with AIDS. Multiple anogenital ulcerations were the most frequent cutaneous presentation (66.7%). Most cytopathic changes were found in the dermis, particularly within the vascular endothelial cells (77.8%) and macrophages (66.7%). However, the association of CMV with concurrent HSV infection was even lower than that seen in patients with AIDS. Only one patient revealed a co-existing cutaneous HSV infection.

CONCLUSIONS

In non-AIDS individuals, the cutaneous lesions from CMV infection showed similar clinical and histopathological features to those of patients with AIDS. However, skin lesions may not be highly associated with HSV, and CMV does seem to contribute to lesion development as a cutaneous manifestation among the CMV infected, non-AIDS, immunocompromised patients.

Viral skin infections in the elderly: diagnosis and management

Over the past several years, there have been advances in the diagnosis and treatment of cutaneous viral diseases in elderly patients. Herpes zoster is caused by reactivation in adults of the varicella-zoster virus (VZV) that causes chickenpox in children. For many years, aciclovir was the gold standard of antiviral therapy for the treatment of herpes zoster. Famciclovir and valaciclovir are newer antivirals, which offer less frequent administration. Postherpetic neuralgia (PHN) refers to pain lasting 2 months or more after an acute attack of herpes zoster. The pain may be constant or intermittent. The treatment of established PHN may include topical anaesthetics, analgesics, tricyclic antidepressants and anticonvulsants, and nonpharmacological therapy may be used to complement such treatment. Therapeutic strategies to prevent PHN include the use of oral corticosteroids, nerve blocks, and treatment with standard antiviral therapy. The three most recently discovered human herpes viruses (HHV-6, HHV-7 and HHV-8), in common with the other members of the family, may cause a primary infection, establish latent infection in a specific set of cells in their host, and then reactivate if conditions of altered immunity develop. These viruses have been associated with an array of disorders, which are important for the clinician to recognise. Cytomegalovirus (CMV) is a member of the herpesvirus family that is very prevalent worldwide. More than 80% of primary infections and 20% of reactivation-producing symptoms occur in transplant populations. Treatment options include intravenous administration of ganciclovir, foscarnet or cidofovir. Herpes simplex virus (HSV) most commonly affects the genital and perioral regions. In the elderly, HSV infection is typically manifest at the vermilion border of the lip. The main concern of recurrent herpes labialis in the elderly is related to potential autoinoculation of the eye or genital area. Treatment with aciclovir, famciclovir or valaciclovir is indicated for these infections. Molluscum contagiosum is caused by a poxvirus, which produces cutaneous lesions that appear as small, firm, umbilicated papules. Immunocompromised patients often do not respond to the usual destructive therapies, and intravenous or topical cidofovir may be useful in these patients.

Cytomegalovirus neuritis in perineal ulcers

BACKGROUND

Although a range of cytomegalovirus (CMV)-induced cutaneous manifestations is described in AIDS patients, skin involvement in immunocompromised patients is rare, and intraneural CMV inclusions or CMV neuritis has not been documented in skin biopsies.

METHODS AND RESULTS

Cutaneous biopsies of CMV lesions were collected prospectively for 12 months. The morphology, sites and symptomatology of the individual lesions, associated systemic illnesses, treatment schedules and disease outcome were recorded. A total of nine biopsies were obtained from three females who presented with extensive painful perineal ulceration and disseminated cutaneous ulcers, nodules and plaques. Clinically, herpes simplex virus (HSV) ulceration was diagnosed and treatment with acyclovir was initiated after biopsies from the natal cleft, perineum and neck were obtained. All were superficial and demonstrated HSV infection. Only the natal cleft biopsy demonstrated coexistent CMV inclusions. Suboptimal healing necessitated two further biopsies from each patient, none of which demonstrated HSV inclusions. Three of four deep perineal biopsies demonstrated CMV inclusions within nerves attended by a lymphocytic infiltrate and architectural disturbances. Two deep cutaneous biopsies of the trunk and abdominal wall confirmed CMV in extraneural locations only. One superficial perineal biopsy did not demonstrate any viral inclusion.

CONCLUSIONS

In documenting CMV neuritis in painful perineal ulcers, the histopathological spectrum of perineal CMV ulcers is expanded, a cutaneous neurotropic characteristic of CMV is presented and a direct role for CMV in the pathogenesis of pain is suggested. CMV latency within perineal nerves is also revisited as another potential site of CMV reactivation in immunocompromised patients, and another potential site for possible venereal transmission of CMV infection. The exclusive presence of HSV in initial superficial biopsies highlights the need for optimally biopsied tissue to confirm the coexistence of CMV infection.

Cytomegalovirus infections

Over the past two decades, there has been an escalation in the number of patients undergoing immunosuppressive therapy following solid organ or bone marrow transplantation, as well as a dramatic increase in the incidence of AIDS. As a result, human cytomegalovirus (HCMV)--once considered a neonatal disease--has captured great interest and importance as a major pathogen in both immunocompromised and immunocompetent patients. Like other members of herpesviridae family, HCMV establishes latency in myeloid lineage cells with potential for reactivation. The natural history of HCMV infection can be divided into primary infection, latency, and reinfection. This review article briefly discusses the molecular pathogenesis of HCMV, then focuses on the clinical picture of this disease, with emphasis on the skin pathology. Diagnostic methods and treatments are also discussed.
