Herpes simplex virus 1 and cytomegalovirus are associated with pemphigus vulgaris but not with pemphigus foliaceus disease

Pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are blistering autoimmune diseases that depend on interaction between genetic and environmental factors. Viral infections, like herpes simplex viruses 1 and 2 (HSV1/2), cytomegalovirus (CMV), Epstein‐Barr virus and dengue virus, could trigger or exacerbate pemphigus. IgM and IgG antibodies against these viruses in serum from PV and PF, their relatives and controls were determined. HSV1/2 expression was evaluated by direct immunofluorescence (DIF) and qPCR in affected or not oral mucosa from PV patients compared with uninjured PF mucosa. IgG anti‐HSV1 was higher in the PV group compared with all groups. IgG anti‐CMV resulted higher in PV group compared with PF patients and PV relatives. HSV1 was confirmed by DIF and qPCR on oral samples from patients with PV. Lack of HSV1 expression in the oral mucosa of patients with PF corroborate that immunosuppressive therapy cannot be the main cause for HSV1 replication in PV disease.

Intractable genital ulcers from herpes simplex virus reactivation in drug‐induced hypersensitivity syndrome caused by allopurinol

Background Drug‐induced hypersensitivity syndrome (DIHS/DRESS) is a severe adverse systemic reaction. Reactivation of human herpesvirus (HHV) family members other than HHV‐6 has been reported in patients with DIHS. Reactivation of HHV family members is generally characterized by increased serum antibody titers against the virus. By contrast, clinical symptoms caused by viral reactivation are relatively rare. Method We report a case of DIHS with intractable genital ulcers from reactivation of herpes simplex virus (HSV) in accordance with reactivation of HHV‐6 and cytomegalovirus (CMV). Result Twenty‐two days after the onset of the rash, the patient developed intractable genital ulcers that were resistant to treatment. Histological examination of the ulcers revealed necrotic degeneration in the epidermal cells, with giant cells containing inclusion bodies and marked lymphocytic infiltration in the upper dermis. Immunohistochemical staining with antibodies reactive to HSV or CMV showed that these giant cells were positive for HSV but negative for CMV. Conclusion Genital herpes is a common skin disease. However, our case was considered to be a DIHS‐associated symptom, not an accidental complication, as the symptoms were severe and resistant to treatment.     

Sexually transmitted viral infections in various population groups in Mogadishu, Somalia.

The prevalence of serum antibodies to human immunodeficiency virus (HIV), herpes simplex virus (HSV), and cytomegalovirus (CMV) and of hepatitis B virus (HBV) markers was investigated in different population groups, including prostitutes, in Mogadishu, Somalia. Hepatitis B surface antigen (HBsAg) was detected in 37% of pregnant women, 4% of neonates, 22% of educated women, and 20% of prostitutes. No significant difference between the groups was observed for HBV. In contrast to figures reported from South East Asia, the prevalence of hepatitis Be antigen (HBeAg) was 18% in prostitutes and only 3% in all other HBsAg positive subjects. The prevalence of antibodies to HSV (100%) and CMV (90%) was very high, but antibodies against HIV were not detected in any of 471 sera. As the routes of transmission for HBV and HIV infections are considered to be similar, HIV will probably spread rapidly in Somalia once this virus has been introduced into the country.     

The association of pityriasis rosea with cytomegalovirus,Epstein-Barr virus and parvovirus B19 infections - a prospective case control study by polymerase chain reaction and serology

A viral aetiology is suspected for pityriasis rosea (PR). The objective was to investigate the association of PR with cytomegalovirus (CMV), Epstein Barr virus (EBV) and parvovirus B19 infections. Patients with PR were recruited in a primary care setting over 18 months. Blood was collected at initial presentation and four weeks later. Controls were the next age-and-sex-matched patients requiring blood collection for non-dermatological disease. Polymerase chain reaction was performed for EBV and parvovirus B19 DNA. Serology was done for CMV, EBV and parvovirus B19. 12 patients with PR and 12 control subjects were recruited. No patient had viral DNA or significant antibody rise against any of the viruses investigated. The seroprevalence of all three viruses and Ab titres in the patients with PR were insignificantly different from those of control subjects. Two patients had IgM detectable against CMV and EBV respectively. Based on other investigation results, we believe that both IgM results were caused by cross reactivity. PR is not associated with CMV, EBV or parvovirus B19 infections.     

Cold urticaria. Clinical findings in 220 patients

Patients with cold urticaria, a total of 220, were studied in Finland. Sixty-three percent of the patients were female. The diagnosis was based on a positive ice cube test in 90% of cases, and the other cold tests were needed to certify the diagnosis for the remainder of patients. The mean age at the onset of the disease was 25.1 years (range, 1-74), and the mean duration of symptoms was 6.3 years (range, 3 weeks to 37 years). Cold urticaria symptoms had disappeared in fifty-three patients (24%), but there was a recurrence of the disease in twelve. Idiopathic (primary acquired) cold urticaria was present in 96% of the patients. Only two patients had a secondary acquired cold urticaria. Two patients had cold-induced, "cholinergic" urticaria, and four patients had a delayed type of cold urticaria. Twenty-one percent of the patients had dermatographism, 8% had cholinergic urticaria, and two patients (1%) had heat urticaria concurrently with cold urticaria.     

The effect of herpesvirus infection on the expression of cell adhesion molecules on cultured human dermal microvascular endothelial cells

Cell-mediated immune response to herpes simplex virus (HSV) may be important in the pathogenesis of herpes keratitis, erythema multiforme or Behcet's disease. We examined whether herpesvirus infection regulates the expression of cell adhesion molecules on cultured human dermal microvascular endothelial cells (HDMEC) and the regulation of T-lymphocytes binding to HDMEC. The expression of intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), or E-selectin on HDMEC increased significantly after treatment with HSV-1, HSV-2, or measles virus on HDMEC. Anti-IL-1 alpha antibody or anti-TNF alpha antibody partially inhibited the expression of ICAM-1, VCAM-1, or E-selectin on HDMEC. The binding of T-lymphocytes to HDMEC increased significantly after the treatment of HSV-1 or measles virus on HDMEC. The binding of T-lymphocytes to HDMEC was significantly inhibited after 16 h of incubation following treatment with anti-ICAM-1 antibody, anti-IL-1 alpha antibody or anti-TNF alpha antibody to HDMEC. These study results suggest that HSV induces the increased expression of ICAM-1, or induction of VCAM-1 and E-selectin on HDMEC and that among these adhesion molecules, the expression of ICAM-1 on HDMEC mainly regulates the binding of T-lymphocytes to HDMEC. The data also suggest that IL-1 alpha or TNF alpha which was produced by HSV infected HDMEC may be related to these events.     

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.     

Immune responses to herpes simplex virus in patients with facial herpes simplex and those with eczema herpeticum

The immune response to herpes simplex virus (HSV) was studied in 59 patients with primary and recrudescent facial HSV infections. The patients included nine with atopic eczema, seven of whom had eczema herpeticum (EH). All patients had antibodies to HSV (measured by ELISA) and all but three had HSV-specific cell mediated immunity (CMI) (measured by in vitro lymphoproliferation). Thirteen control subjects were negative for both tests. All three patients with absent CMI to HSV had suffered from severe EH and had depressed CMI to HSV for several months following an attack. In two of these EH patients, a positive CMI response was produced by in vitro removal of CD8 + ve T lymphocytes from peripheral blood mononuclear cells using a panning technique. Thus the absence of CMI to HSV in these patients was due to suppressor cell function rather than a lack of specifically responsive cells. The other four EH patients with normal CMI to HSV had suffered less severe EH, but no association between the absence of CMI to HSV and serum IgE level or activity of the eczema was apparent in the atopic patients. No specific anti-HSV IgE antibody was detectable.     

Is HSV serology useful for the management of first episode genital herpes?

BACKGROUND: First episode genital herpes simplex virus (HSV) infections can be classified into three groups, primary genital herpes (no previous exposure to HSV), non-primary first episode (IgG antibody to HSV of the non-presenting type), and first episode with pre-existing IgG HSV antibodies. The use of IgM to classify first episode genital herpes has not been evaluated. OBJECTIVE: To evaluate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of HSV-1 and HSV-2 IgM antibodies for the diagnosis of first episode genital herpes, when compared with clinical diagnosis. METHODS: Patients with a first clinical episode of genital herpes were recruited. Sera were tested for IgG antibodies to HSV-2 using an indirect enzyme linked immunosorbent assay (ELISA). Equivocal results were resolved by western blot. HSV-1 IgG and IgM and HSV-2 IgM antibodies were detected using western blot. RESULTS: 157 patients were recruited. 31 were excluded (missing data or no detectable antibodies and negative viral isolation). Therefore, 126 patients were included in the analysis. 23 (18.3%) had primary genital herpes, 34 (27.0%) non-primary first episode, and 69 (54.8%) had pre-existing genital herpes. The specificity and PPV of HSV IgM was 100%; the sensitivity was 79% and the NPV 85%. CONCLUSION: IgM HSV serology may be useful in the management of some patients with first episode genital herpes and provide an indication of the source of infection. Drawbacks include the low sensitivity and NPV, lack of availability, IgM antibodies may occasionally be produced in response to recurrent infection and, finally, IgM antibodies may take up to 10 days to develop and last 7-10 days.     

Premarket evaluation of the POCkit HSV-2 type-specific serologic test in culture-documented cases of genital herpes simplex virus type 2 [see comment

BACKGROUND AND OBJECTIVES: The genital herpes epidemic continues, in part, because patients with subclinical or atypical presentations cannot be identified by most herpes simplex virus (HSV) antibody tests. A new product, POCkit HSV-2, has been developed to rapidly and accurately detect antibodies to HSV type 2 (HSV-2) in capillary blood or serum. GOAL: Sera from patients with culture-documented genital or oral herpes were tested to determine the sensitivity and specificity of the POCkit HSV-2 rapid point-of-care antibody test (Diagnology, Belfast, Northern Ireland). STUDY DESIGN: Sera from 50 patients with culture-documented HSV type 1 (9 oral, 41 genital) and from 253 patients with genital HSV-2 were tested by POCkit HSV-2 for HSV-2 antibodies. Each subject had a positive culture for HSV within 6 months of serum collection. Sera were preselected to include only those that were seropositive to the respective virus subtype by University of Washington Western blot. RESULTS: Compared with viral culture and Western blot analysis, sensitivity of the POCkit HSV-2 test for HSV-2 antibody was 96%; specificity was 98%. CONCLUSION: This test provides rapid, accurate identification of HSV-2 antibody in subjects with established HSV infections.     

Secretory IgA against herpes simplex virus in cervical secretions.

A recently developed method to recover proteins from cervical secretions was combined with methods to detect minute concentrations of herpes simplex virus (HSV) type specific antibodies to measure the concentrations of locally produced antibodies in women with genital infections. Forty nine women attending a sexually transmitted disease (STD) clinic were included. Cervical secretions were obtained by suction into a plastic catheter. Soluble proteins were recovered from the secretions by elution with hyperosmolar sodium chloride. A rabbit antibody to human secretory component, which was conjugated to horseradish peroxidase, was used to measure secretory IgA (S-IgA) that was HSV type specific. For comparison, HSV type specific IgG was measured in serum samples from the patients. Of the 49 women, 16 yielded detectable HSV type 2 (HSV 2) S-IgA in secretions. Twelve of them also reacted to the HSV type common antigen, but only five had HSV 2 IgG detectable in their serum. S-IgA against HSV was found in significantly more women with a clinical diagnosis of acute cervicitis than in others. This could be explained by a general increase in local antibody production and immunity triggered by previous contacts with HSV. It is concluded that local mucosal immunity to HSV 2 can be detected in women who do not have a specific humoral antibody response to the virus. For seroepidemiological studies of infection with HSV 2 this local immunity may be considered to be a factor that gives an underestimation of the true incidence of HSV 2 infection.     

Viral DNA detection and RAS mutations in actinic keratosis and nonmelanoma skin cancers

Background Actinic keratosis (AK) is a well‐established precancerous skin lesion that has the potential to progress to squamous cell carcinoma (SCC). Basal cell carcinoma (BCC) is a locally aggressive slowly growing tumour that rarely metastasizes. A number of viruses have been proposed to play a role in the development of nonmelanoma skin cancers (NMSC), but the most plausible evidence to date suggests that cutaneous human papillomavirus (HPV) is the key instigating factor. Objectives To evaluate the prevalence of HPV, cytomegalovirus (CMV), herpes simplex virus (HSV) and Epstein–Barr virus (EBV) and investigate their relationship with the presence of RAS gene mutations in cutaneous lesions obtained from nonimmunosuppressed patients. Methods HPV, CMV, HSV and EBV detection was performed using polymerase chain reaction (PCR) in skin biopsies (26 AK, 12 SCC and 15 BCC samples) that were collected from immunocompetent patients. The RAS mutation incidence was also investigated in all cutaneous lesions by use of PCR/restriction fragment length polymorphism and direct DNA sequencing. Results Seventeen out of 53 (32%) skin lesions were found to be positive for HPV DNA. The highest incidences of HPV infection were five of 15 (33%) in BCC and four of 12 (33%) in SCC specimens. The HPV incidence was eight of 26 (31%) in AK and eight of 53 (15%) in normal skin tissue. Twelve out of 53 (23%) skin lesions were CMV‐positive. The highest incidence of CMV infection was six of 15 (40%), observed in BCC specimens. The CMV incidence was two of 26 (8%) in AK and four of 12 (33%) in SCC. No normal skin biopsy was found to be positive for CMV. All cutaneous samples were negative for HSV and EBV DNA, as assessed by our PCR‐based assays. Only three samples, one AK (4%), one BCC (6%) and one SCC (8%), were found to carry a G>T transversion at the second position of HRAS codon 12. Both HRAS mutant SCC and BCC biopsies were HPV‐ and CMV‐positive, as well. Conclusions HPV DNA is detected in NMSC, AK and normal skin biopsies. Our results also indicate that CMV is involved in NMSC at higher levels than in premalignant lesions, whereas the virus was not detected in normal skin biopsies. HSV and EBV do not appear to be involved in the pathogenesis of cutaneous lesions. Moreover, we suggest that the HRAS codon 12 mutation is not a very common event in AK or NMSC. Finally, both viral infection and HRAS activation appear to represent independent factors in the aetiology of NMSC, samples of which were obtained from immunocompetent 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.     

The juvenile variant of papular-purpuric gloves and socks syndrome and its association with viral infections

BACKGROUND: Papular-purpuric gloves and socks syndrome (PPGSS) occurs mostly in adults and has been shown to be related to several possible viral infections. However, childhood-onset PPGSS seems to be not so rare as previously thought in our clinical experience. OBJECTIVES: To survey the general characteristics of childhood-onset PPGSS and to determine the possible association between this juvenile variant of PPGSS and various viral infections. PATIENTS AND METHODS: Thirty-three children with erythematopurpuric papular eruptions on the hands and/or feet were enrolled. Detailed history-taking and physical examination were performed on all of them. Blood samples were obtained from 25 patients about 1-5 weeks after the appearance of cutaneous eruptions to check complete blood counts, differential white blood cell counts, and IgM and IgG antibodies to parvovirus B19, cytomegalovirus (CMV), viral capsid antigen of Epstein-Barr virus (EBV) and measles. RESULTS: The median age of these 33 patients was 23 months. The mean duration of the skin eruption was 4.8 weeks (SD 2.7, 95% CI 3.9-5.0). Lymphocytosis was present in 13 patients (52%) while mild eosinophilia occurred in only three patients (12%). Five patients (20%) were positive for IgM antibodies against CMV and seven (28%) were positive for IgM antibodies against EBV. Only one patient (4%) was detected to have IgM antibodies against parvovirus B19. CONCLUSIONS: Childhood-onset PPGSS shows somewhat different clinical features from the adult type. It may represent a nonspecific manifestation of several viral infections, including CMV, EBV and parvovirus B19 infections.     

Chronic urticaria is not significantly associated with hepatitis C or hepatitis G infection: a case-control study

OBJECTIVE: To study the prevalence of hepatitis C virus (HCV) and hepatitis G virus (HGV) infection in patients with chronic urticaria. DESIGN: Prospective case-control study and literature review. SETTING: Dermatology department of an academic medical center in Strasbourg, France. PATIENTS: One hundred ten consecutive patients with typical urticaria lasting longer than 2 months were seen between March 1, 1997, and August 31, 1998. None had a history of viral hepatitis. Age- and sex-matched patients (n = 110) seen in the same department and during the same period were included for controls. None of the controls had a history of urticaria, pruritic dermatosis, or hepatitis. MAIN OUTCOME MEASURES: The detection of HCV antibodies through a third-generation enzyme-linked immunosorbent assay. To detect early HCV infection without plasmatic antibodies, genomic amplification of HCV RNA was carried out in all patients using 2 different methods. Hepatitis G virus RNA was detected only by genomic amplification. All measures were planned before data collection. RESULTS: Antibodies to HCV were found in 1 patient with urticaria and in 1 of the control group (0.9% of each group). None had circulating HCV RNA, and liver function test results were within the reference range. Genomic amplification without HCV antibodies was not observed. Two patients with urticaria and 2 of the control group (1.8% of each group) had circulating HGV RNA, but they had neither coinfection with HCV nor changes in their liver function test results. CONCLUSIONS: Systematic HCV screening in patients with chronic urticaria is not cost-effective, at least in Europe, because hepatitis C rates were similar to those of the general population. We could not confirm the hypothesis that urticaria occurs in an early phase of HCV infection-ie, before evidence of HCV can be detected by serologic testing. Hepatitis C virus is unlikely to be the cause of urticaria in the infected patient detected in this study because of the absence of HCV RNA and changes on liver function tests. Hepatitis G virus is also unlikely to be a cause of urticaria, as the rate of HGV positivity in this study was even lower than that in the general French population.     

Skin autoreactivity in Hashimoto's thyroiditis patients without urticaria: autologous serum skin test positivity correlation with thyroid antibodies, sonographical volume and grading

Recent studies have shown an association between anti-thyroid antibodies and autologous serum skin test (ASST) positive urticaria patients. However, a connection between thyroid and this reliable skin test for mast cell autoreactivity, ASST, has not been reported yet. We investigated ASST in patients with Hashimoto's thyroiditis (HT) without urticaria and compared the results with laboratory and sonographical findings of HT. 154 HT patients, 100 healthy volunteers without HT as a first control group and 46 patients with multinodular goitre but without autoimmune thyroid disease as a second control group underwent testing with ASST. ASST was applied to these groups according to two criteria, first as ASST(new): autologous serum red wheal response 1.5?mm bigger than negative control; second as ASST(old): serum red wheal response 5?mm bigger than negative control accepted as positive. Free triiodothyronine (fT3), free thyroxine (fT4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (anti-TPO) and thyroglobulin antibody (anti-Tg) levels were measured. ASST(old), ASST(new) scored positive in 51.3-60.4% of HT patients, with statistically significant differences. Thyroid volume grades were inversely proportional with ASST(old) and (new) positivity. Moderate (+) titers of anti-Tg in ASST(old) and (new) (+) cases were significantly higher than the same titers of anti-Tg in ASST(old) and (new) (-) cases. The prevalence of ASST positivity in HT patients was not affected by the following factors: gender, age at screening, laboratory measurements of thyroid function tests, anti-TPO antibodies and thyroid ultrasound (US) echogenicity. Positivity of ASST in HT has shown that there is a skin mast cell autoreactivity in HT patients independent of autoreactive chronic urticaria (ACU).     

Clinical course of cervical human papillomavirus lesions in relation to coexistent cervical infections.

A prospective follow-up of 530 women with cervical human papillomavirus (HPV) infection was conducted from 1981 to the present (mean 62.9 months). The patients were examined by PAP smears and colposcopy with or without biopsies every sixth month. Endocervical swabs were taken for culture of cytomegalovirus (CMV), herpes simplex virus (HSV), and Chlamydia trachomatis at each visit. During the follow-up period, 179 of the 530 patients (33.8%) had cervical infection and 351 (66.2%) had no coexistent cervicitis. On average, the patients with coexistent cervicitis were younger than those without cervicitis (32 +/- 7.2 years and 37.1 +/- 11.4 years, respectively; P less than 0.0001). C. Trachomatis was isolated from 95 of the 530 women (17.9%), and 19 of the patients had chlamydial cervicitis twice. Cytomegalovirus was isolated from 27 (5.1%) women, 2 of whom also had HSV, and 12 patients had a chlamydial infection. Herpes simplex virus was isolated from 11 (2.1%) women, including 2 patients with coexistent CMV infection. A total of 60 (1.3%) women had nonspecific cervicitis. Of the HPV lesions without coexistent cervical infection, 56.7% regressed, 24.5% persisted, 16.5% progressed, and recurrence was found in 2.3%. The corresponding figures for HPV lesions with coexistent cervicitis were as follows: 66.5%, 22.9%, 9.5%, and 1.1%, respectively. Coexistent active cervical infections had no influence on the clinical course of HPV lesions.     

Association of cytomegalovirus and herpes simplex virus infections of the cervix in four clinic populations

The rates of isolation of cervical cytomegalovirus (CMV) and herpes simplex virus (HSV) were compared for populations of four different clinics attended by a total of 1,755 women. The prevalence of CMV infection could be predicted by the prevalence of HSV infection, with CMV being 2.5 times as prevalent as HSV in each population. The overall infection rates for CMV and HSV were 4.1% and 1.7%, respectively. The 252 women attending the Sexually Transmitted Disease Clinic had significantly higher rates of CMV and HSV infection (12.5% and 5.6%, respectively) than populations attending the other clinics. A strong relationship between marital status and CMV infection was observed. The estimated relative risk for single compared to married women was 2.9. These data verify the importance of the sexual route of transmission in the epidemiology of cervical infection with CMV.     

Infection with human immunodeficiency virus (HIV) and cytomegalovirus in a London health district 1980-4.

By testing serum samples taken between 1980 and 1984 from men attending a department of sexually transmitted diseases, it was shown that antibodies to human immunodeficiency virus (HIV) first appeared in 1981. Homosexual men were significantly more likely to have antibodies to HIV and to cytomegalovirus (CMV) than were heterosexual men attending the same clinic. This shows that homosexuals are exposed to both HIV, the cause of the acquired immune deficiency syndrome (AIDS), and to CMV, which can reactivate to cause life threatening disease once immunosuppression has developed. All homosexuals, not just those with antibodies against HIV, had raised levels of CMV antibodies. This suggests that they experience frequent antigenic stimulation after reinfections with CMV or reactivation of endogenous virus.
