Care of HIV-positive women aged 50 and over - can we do better?

A sample of 123 HIV-positive women aged 50 years and over showed high rates of late diagnosis with CD4 count <350 (71%), significant co-morbidities (90%), high rates of premature menopause (6.8%) and early menopause (6.8%) and cervical cytological abnormalities (47%). Specific interventions to improve care in this group should include yearly cervical cytology, early counselling with regard to reproductive options, menopause management and screening for sexually transmitted infections (STIs).

Automatic oral fluid-based HIV testing in HIV screening programmes: automatic for the people.

OBJECTIVES: UK guidelines recommend routine HIV testing in general clinical settings when the local HIV prevalence is > 0.2%. During pilot programmes evaluating the guidelines, we used laboratory-based testing of oral fluid from patients accepting tests. Samples (n = 3721) were tested manually using the Bio-Rad Genscreen Ultra HIV Ag-Ab test (Bio-Rad Laboratories Ltd, Hemel Hempstead, UK). This was a methodologically robust method, but handling of samples was labour intensive. We performed a validation study to ascertain whether automation of oral fluid HIV testing using the fourth-generation HIV test on the Abbott Architect (Abbott Diagnostics, Maidenhead, UK) platform was possible. METHODS: Oral fluid was collected from 143 patients (56 known HIV-positive volunteers and 87 others having contemporaneous HIV serological tests) using the Oracol+ device (Malvern Medicals, Worcester, UK). Samples were tested concurrently: manually using the Genscreen Ultra test and automatically on the Abbott Architect. RESULTS: For oral fluid, the level of agreement of results between the platforms was 100%. All results agreed with HIV serology. The use of the Oracol+ device produced high-quality samples. Subsequent field use of the test has shown a specificity of 99.97% after nearly 3000 tests. CONCLUSIONS: Laboratory-based HIV testing of oral fluid requires less training of local staff, with fewer demands on clinical time and space than near-patient testing. It is acceptable to patients. The validation exercise and subsequent clinical experience support automation, with test performance preserved. Automation reduces laboratory workload and speeds up the release of results. Automated oral fluid testing is thus a viable option for large-scale HIV screening programmes.

Role of penile biopsy in the diagnosis of penile dermatoses.

The aim of this study was to review the utility of penile biopsy in genitourinary (GU) medicine clinics, its acceptability and the range of penile dermatoses diagnosed histologically. A retrospective case-notes review of 401 cases attending a dedicated penile dermatoses clinic from 1 June 2001 to 30 November 2007 was carried out. In 115/401 (28.7%) of cases a biopsy was invoked to resolve ambiguities of diagnosis. In 60/401 (15%) of those cases differential diagnosis was resolved, in 26/401 (6.5%) clinically suspected diagnoses were confirmed and in 22/401 (5.5%) clinically unsuspected diagnoses were identified. In 7/401 (1.7%) of cases the biopsy was also the treatment. Targeted penile biopsy has an important role in the diagnosis of penile dermatoses, particularly where there is clinical uncertainty. As a diagnostic tool in GU medicine departments it should be readily available even if not for routine use. There were indications that circumcision may reduce the incidence of penile dermatoses. There was also some indication of a possible ethnic factor in the relative incidences of penile lichen sclerosus and lichen planus in biopsied patients.

Two for the price of one.

This case is about an HIV seropositive young woman referred for the treatment of severe menorrhagia causing anaemia due to adenomyosis where the levonorgestrel-releasing intrauterine system (Mirena) proved useful in treating her heavy periods and also provided effective contraception without interference from the liver enzyme-inducing effects of antiretroviral medications.

Contraception and medical gynaecology for HIV-positive women in a one-stop clinic.

HIV-positive women may be reluctant to attend gynaecology or family planning clinics for fear of divulging their condition. Therefore, a referral clinic was opened within the HIV clinic. Retrospective case-note reviews of 197 new patients revealed 109 with a variety of medical gynaecology conditions (menorrhagia being the commonest) and 88 sought contraception. The full range of contraceptives was used, including Mirena for the treatment of menorrhagia as well as contraception and the combined pill adjusted for interaction with liver enzyme-inducing antiretroviral drugs. The acceptance of contraceptive advice and gynaecological evaluation by the patients has resulted in improved reproductive health services for these HIV-positive women. In centres with large cohorts of HIV-positive women, this type of one-stop specialist clinic will be very effective in providing high-quality reproductive health care and hence, this type of clinic is recommended for such centres.

Awareness of HIV post-exposure prophylaxis after sexual exposure and emergency hormonal contraception in HIV-positive women.

Women attending a dedicated medical gynaecology and family planning referral clinic for women with HIV were surveyed using a standard questionnaire about their knowledge and attitudes to post-exposure prophylaxis after sexual exposure (PEPSE) and emergency hormonal contraception (EHC). Eighty percent of them had not heard of PEPSE, but once informed about it, 86% said they would inform a partner about it. Less than 10% had any idea of the duration of effectiveness. Seventy-three percent of the women knew about EC and 45% of them had used it previously. Ninety-eight percent of them would use it in the future if necessary. Eighty percent of them knew its period of effectiveness. There is a clear need for information about PEPSE, which needs to be delivered around the time of HIV diagnosis and reinforced later. Some women will need help in discussing it with HIV-negative partners.

The epidemiology of genital infection with herpes simplex virus types 1 and 2 in genitourinary medicine attendees in inner London.

OBJECTIVE: To characterise the epidemiological and clinical features of genital herpes and the diagnostic role of HSV-2 specific serology in an ethnically diverse cohort of genitourinary medicine (GUM) attendees in inner London. METHODS: Genital swabs (n = 186) were tested by real time polymerase chain reaction (PCR) and serum samples (n = 70) by HSV-2 specific enzyme linked immunoassay (ELISA). RESULTS: Among 186 patients (median age 29 years), 104/186 (56%) were male and 176/186 (95%) heterosexual; ethnicity was predominantly black Caribbean (76/186, 41%), white (65/186, 35%), or black-African (41/186, 22%). The most common lesion sites were penis (85/104 men, 82%) and vulva (63/82 women, 77%); 114/186 (61%) patients were diagnosed clinically with first episode disease. Women were more likely to present <5 days of onset (p = 0.008). Black Caribbean patients were more likely to present > or = 5 days (p = 0.04) and decline HIV testing (p = 0.03). By PCR, 108/186 (58%) swabs tested positive for HSV-1 (7/108, 6.5%) or HSV-2 (101/108, 93.5%). Independent predictors of a positive PCR were heterosexual group, <5 days of onset, and visible genital ulceration on examination. HSV-2 was associated with black Caribbean and black African ethnicity; HSV-1 with white ethnicity (p = 0.006). By HSV-2 specific serology, 16/42 (38%) first episodes caused by HSV-2 were recurrent infections, and 7/19 (37%) patients with recurrent genital disease but negative PCR had genital herpes. CONCLUSIONS: Epidemiological trends in genital HSV-1 and HSV-2 infection appear to vary between ethnic groups in the United Kingdom. HSV-2 specific serology improves diagnostic accuracy in GUM populations where most genital infections are caused by HSV-2.

Diagnosis of genital herpes by real time PCR in routine clinical practice.

BACKGROUND: Virus isolation in cell culture is the recognised diagnostic gold standard for genital herpes. Although increasing evidence indicates that polymerase chain reaction (PCR) provides a more rapid and sensitive diagnostic method, its implementation in routine diagnostic settings has been limited by concerns over contamination and cost. OBJECTIVE: To evaluate the feasibility of replacing virus culture with PCR for the diagnosis of genital herpes in settings serving large populations of genitourinary medicine (GUM) attendees. METHODS: Genital swabs collected from 233 consecutive GUM attendees with suspected genital herpes were tested in parallel by virus culture and automated real time PCR. Three specimen preparation methods were evaluated and the assay reliability was assessed by repeat testing, comparison with a commercially available assay, and herpes simplex virus (HSV) sequence analysis. Probe melting temperatures (Tm) were used to differentiate between HSV types without additional post-PCR steps. RESULTS: HSV was detected in 79/233 (34%) samples by virus culture and 132/233 (57%) samples by PCR. PCR significantly increased HSV detection in both early (< 5 days) and late (> or = 5 days) presentations and in both first and recurrent episodes. HSV detection and typing by PCR was achieved within less than 4 hours leading to a significant reduction in labour compared to virus culture. Most specimens (120/132, 91%) were typed as HSV-2. Results were highly reproducible. CONCLUSIONS: Real time PCR is a highly reproducible, rapid, and labour efficient method for HSV detection in genital swabs. Its implementation is feasible in routine diagnostic settings.

Ethnic variation in type of genital herpes simplex virus infection in a South London genitourinary medicine clinic.

The aims of this study were to investigate the prevalence of herpes simplex virus (HSV) types 1 and 2 in the study population and correlate the results with clinical and demographic details. Consecutive HSV isolates from 334 clinic attendees were typed by immunofluorescence. Patient information was collected from the case notes. Overall, HSV-1 was isolated from 48 and HSV-2 from 287 samples, respectively. There was no significant difference in isolation rates according to gender. However, 33% of white patients' isolates typed as HSV-1, while only 6% of the isolates from the black population were HSV-1 (P < 0.001). Initial infections were seen in 81% of HSV-1 infections and 48% of HSV-2 infections, respectively. A wide discrepancy was observed in the prevalence of HSV-1 and HSV-2 infections between the ethnic groups in this population, which was not explained in terms of gender or age. This may reflect different exposure to HSV-1 in childhood or different sexual practices. The increased prevalence in genital HSV-1 reported in recent studies was not seen in this population. However, the differing proportions of primary and first episode infections may reflect a changing epidemiology.

Oral manifestations of an HIV positive cohort in the era of highly active anti-retroviral therapy (HAART) in South London.

BACKGROUND: Human Immunodeficiency Virus (HIV) infection is associated with oral manifestations of diagnostic and prognostic importance. With the advent of Highly Active Anti-retroviral Therapy (HAART) there is anecdotal evidence to suggest that the prevalence of oral lesions has declined. The number of prevalence studies, carried out in the era of HAART is, however, meagre. Our aim was to study the prevalence of the oral manifestations of HIV in a population, predominantly on HAART, attending a Genito-Urinary Medicine Centre in South London. METHODS: This cross sectional study included 203 adult volunteers, comprising 76% males and 24% females. One third of the subjects were from the predominantly African or Afro- Caribbean ethnic minority groups resident in London. The relationship between the prevalence of oral lesions and demographic variables, therapeutic regimes, viral load and CD4 counts were evaluated. RESULTS: One hundred (49%) of the patients had no detectable oral lesions. Oral lesions detected most frequently included oral hairy leukoplakia (9.9%), HIV associated periodontal diseases (9.9%) and oral candidiasis (4.9%). Three subjects had multiple papillomatous growths. Most cases (n = 17/20) of oral hairy leukoplakia were in individuals with a detectable (> 400 copies/ml) plasma RNA viral load. The majority (n = 8/10) of our patients with oral candidiasis had a plasma RNA viral load > 10,000 copies/ml and half (n = 5/10) had a CD4 count < 200 cells/mm3. Logistic regression analysis suggested that the presence of an oral lesion was not associated with any demographic features except for periodontal diseases which were associated with tobacco smoking (P = 0.023). CONCLUSIONS: The prevalence of so called 'strongly associated' oral lesions of HIV is low in this South London HIV-infected population on HAART, and the relative frequency is different from that cited in the literature from the pre-HAART era. The oral lesions detected were found mostly in people with low CD4 counts and high HIV-1 RNA viral loads, suggesting they were very immunocompromised, not on, or declining therapy, or that their therapy was failing.

Detection of human herpesvirus 8 DNA in semen from HIV-infected individuals but not healthy semen donors.

OBJECTIVE: To ascertain the prevalence of Kaposi's sarcoma-associated herpesvirus (KSHV), also known as human herpesvirus (HHV) type 8, and cytomegalovirus (CMV) DNA in semen was investigated. METHODS: Amplification by nested polymerase chain reaction was used to detect viral DNA sequences in samples from 24 HIV-infected gay men, 15 of them with Kaposi's sarcoma (KS), and 115 healthy donors. RESULTS: Six of the 24 HIV-infected patients had detectable HHV-8 DNA in their semen: three of the 15 patients with KS and three of the nine patients without KS. CMV DNA was detected in 20 semen samples from HIV-infected patients. None of the semen samples from healthy donors had detectable HHV-8 DNA and rates of CMV DNA detection were low (3%). CONCLUSIONS: The study demonstrates the presence of HHV-8 in semen from HIV-infected individuals with, or at risk, of developing KS and the potential for sexual transmission of the virus. We found no evidence of HHV-8 in the semen of HIV-uninfected donors.
