Mortality in perinatally HIV-infected young people in England following transition to adult care: an HIV Young Persons Network (HYPNet) audit.

OBJECTIVES: Mortality in young people with perinatally acquired HIV infection (PHIV) following transfer to adult care has not been characterized in the UK. We conducted a multicentre audit to establish the number of deaths and associated factors. METHODS: Fourteen adult clinics caring for infected young people reported deaths to 30 September 2011 on a proforma. Deaths were matched to the Collaborative HIV Paediatric Study, a clinical database of HIV-infected children in the UK/Ireland, to describe clinical characteristics in paediatric care of those who died post-transition. RESULTS: Eleven deaths were reported from 14 clinics which cared for 248 adults with PHIV. For the 11 deaths, the median age at transfer to adult care was 17 years (range 15-21 years), and at death was 21 years (range 17-24 years). Causes of death were suicide (two patients), advanced HIV disease (seven patients) and bronchiectasis (one patient), with one cause missing. At death, the median CD4 count was 27 cells/µL (range 0-630 cells/µL); five patients were on antiretroviral therapy (ART) but only two had a viral load < 50 HIV-1 RNA copies/mL. Nine had poor adherence when in paediatric care, continuing into adult care despite multidisciplinary support. Eight had ART resistance, although all had potentially suppressive regimens available. Nine had mental health diagnoses. CONCLUSIONS: Our findings highlight the complex medical and psychosocial issues faced by some adults with PHIV, with nine of the 11 deaths in our study being associated with poor adherence and advanced HIV disease. Novel adherence interventions and mental health support are required for this vulnerable cohort.

Trends in attendances to genitourinary medicine services by older women.

We sought to analyse reasons for attendance of older women (defined as aged 46 years and over) to genitourinary (GU) medicine services at two UK clinics. We used KC60 coding data to count new episode attendances by year from 1998 to 2008 and to further dissect reason for attendance in 2827 new episodes during 2003-2008. The total number of new episodes of attendance in older women increased from 167 in 1998 to 701 in 2008. Within this overall increase, there was a stable proportion of acute sexually transmitted infections (STIs) over time, alongside significant increases in the proportion of women requesting STI screening and HIV testing and those attending GU medicine for other reasons, such as dermatological or gynaecological complaints. In our clinic population it was encouraging to see that older women increasingly use GU medicine services for STI screening and HIV testing. Services may need to adapt to older women's specific health-care needs.

Microscopy for symptomatic men: not all symptoms are born equal.

We reviewed microscopy results for symptomatic male patients in order to identify clinical correlates of urethritis as diagnosed by same-day microscopy. Higher polymorph counts were found in patients presenting with discharge, or discharge together with dysuria, but dysuria without discharge was strongly associated with negative urethral microscopy. Symptoms were strongly linked to microscopy outcome but partnerships were not linked to either symptoms or outcome.

The need for innovative sexually transmitted infection screening initiatives for young men: evidence from genitourinary medicine clinics across England.

The study objectives were to ascertain behavioural, access-related, health-seeking factors and sexually transmitted infection (STI) prevalence in young men (<25 years) attending genitourinary (GU) medicine clinics and compare them with older men (≥ 25 years) and young women (<25 years). Between October 2004 and March 2005, 4600 new attendees at seven sociodemographically and geographically contrasting GU medicine clinics across England completed questionnaires, which were linked to routine clinical data. Young men waited significantly less time to be seen in clinic compared with older men and young women. They were less likely to report symptoms than older men (P = 0.021) yet more likely to be diagnosed with chlamydia (P = 0.001) and gonorrhoea (P = 0.007). They were also more likely to be diagnosed with an acute STI relative to young women (P = 0.007). Our data confirm the need to make comprehensive STI screening readily available for young men and to develop effective and innovative screening strategies in different settings.

Vertically acquired HIV diagnosed in adolescence and early adulthood in the United Kingdom and Ireland: findings from national surveillance.

OBJECTIVE: The aim of the study was to describe the characteristics of young people with vertically acquired HIV diagnosed aged > or =13 years. METHODS: A retrospective review of HIV diagnoses reported to well-established national paediatric and adult HIV surveillance systems in the United Kingdom/Ireland was conducted. RESULTS: Forty-two young people with vertically acquired HIV diagnosed aged > or =13 years were identified; 23 (55%) were female, 40 (95%) were black African and 36 (86%) were born in sub-Saharan Africa. The median age at HIV diagnosis was 14 years (range, 13-20 years). Half of the patients presented with symptoms; the remainder were screened for HIV following diagnosis of a relative. The median CD4 count at diagnosis was 210 cells/microL (range, 0-689 cells/microL), 12 patients (29%) were diagnosed with AIDS at HIV diagnosis or subsequently, and 34 (81%) started combination antiretroviral therapy (ART), most (31 of 34) within a year of diagnosis. CONCLUSION: A small number of young people with vertically acquired HIV survive childhood without ART and are diagnosed at age > or =13 years in the United Kingdom/Ireland. Half of the patients were asymptomatic, highlighting the importance of considering HIV testing for all offspring of HIV-infected women, regardless of age or symptoms. Increased awareness among clinicians and parents is required to reduce delayed presentation with advanced disease and to avoid onward transmission as these young people become sexually active.

Is vaginal microscopy an essential tool for the management of women presenting with vaginal discharge?

SUMMARY: Point-of-care microscopy is the gold standard for the diagnosis of vaginal discharge in genitourinary (GU) medicine clinics but not used in primary care settings and reproductive health clinics to which many patients present. In our GU medicine clinic setting, we conducted an audit to assess the utility of microscopy of vaginal secretions versus clinical diagnosis alone for the differential diagnosis of uncomplicated lower vaginal infections. Clinical diagnosis (including pH) of bacterial vaginosis had a sensitivity between 85% and 88% at two clinic sites. Our results suggest that it may be safe and more cost-effective to restrict vaginal microscopy to a subgroup of women presenting with vaginal discharge.

Would offering rapid point-of-care testing or non-invasive methods improve uptake of HIV testing among high-risk genitourinary medicine clinic attendees? A patient perspective.

While most genitourinary (GU) medicine clinics achieve a high uptake for testing HIV in new patients, they may still miss testing those at highest risk. Point-of-care testing (POCT) and salivary samples are acceptable and feasible but have not yet been shown to increase uptake among high-risk patients (HRP). This study aimed to describe reasons why HRP decline HIV testing and whether offering POCT along with standard testing would increase the uptake of testing HIV in two London GU medicine clinics. Anonymous self-administered questionnaires were offered to all new and rebooked patients. Eight hundred and ninety-nine questionnaires were analysed of which 598 were HRP. Uptake of HIV testing was 77.1% among HRP and 65.8% among the rest. A total of 51.1% of HRP who declined HIV testing said they would be more likely to accept a POCT and 32.8% a salivary test. Introduction of rapid POCT for HIV would increase patient's choice and may increase the likelihood of HRP accepting an HIV test.

Management of HIV infection in adolescents attending inner London HIV services.

Increasing numbers of HIV-infected children are now reaching adulthood and young people account for 10% of new HIV diagnosis in the UK each year. This audit of young people attending specialist and generic HIV services in Inner London in 2006 (n=39) highlights the complex medical and psychosocial needs of this patient group: 63% were diagnosed with HIV because of poor health, 39% had received more than three antiretroviral regimens, 21% had resistance to two antiretroviral classes and 32% had significant mental health problems. In addition, 45% reported to be sexually active with poor uptake of contraception other than condoms and frequent non-disclosure of their HIV status to a sexual partner.

Sexual behaviour, condom use, and disclosure of HIV status in HIV infected heterosexual individuals attending an inner London HIV clinic.

BACKGROUND: The National Strategy for Sexual Health and HIV for England (2001) emphasised the role of HIV services in reducing secondary transmission of HIV through prevention work with HIV infected people. OBJECTIVE: To determine the sexual behaviour, condom use, and disclosure of HIV status of HIV infected heterosexuals attending an inner London HIV clinic. DESIGN: Cross sectional questionnaire study of heterosexual HIV infected individuals attending an HIV outpatient clinic. METHODS: We collected demographic data for all respondents and sexual behaviour data for those sexually active over the past year using a self administered questionnaire. Viral load and CD4 count for responders and age, sex, ethnicity, viral load, and CD4 count for non-responders were obtained from the clinic database. RESULTS: The response rate was 47.3% (n = 142). 100 participants reported being sexually active in the past year, of whom 73% used condoms when they last had vaginal sex. Knowledge of partner's HIV status was the only variable significantly associated with the participant disclosing their HIV status to their partner (p<0.001). In those who had disclosed their status, only knowledge of partner's HIV status was significantly associated with condom use (p = 0.03). CONCLUSIONS: Issues relating to non-disclosure and partner notification in HIV infected heterosexuals will need to be better understood to improve sexual health in this group and to reduce onward transmission of HIV.

Prevalence of Chlamydia trachomatis in sexual contacts of gonorrhoea.

The British national and local clinic guidelines recommend epidemiological treatment for Chlamydia trachomatis (CT) in patients with gonococcal infection but not their contacts. We aimed to determine the prevalence of CT amongst all gonorrhoea contacts attending over a 30 months period through a retrospective notes review. Of 223 contacts, gonorrhoea was diagnosed in 110 (49.3%) while CT was diagnosed in 54 (24.2%). CT was significantly more prevalent in younger people [(37.8% of contacts <25 years versus 9.6% of contacts >/=25 years (P = 0.000)]. All patients with CT identified as heterosexual except one. Amongst heterosexuals, there was no significant difference in the prevalence between males and females, being 31.6% and 27.8% respectively (P = 0.5995). CT was prevalent in 29.1% of N. gonorrhoeae positive contacts and 19.5% of N. gonorrhoeae negative contacts (p = 0.0935). The high prevalence suggests that epidemiological treatment for CT in gonorrhoea contacts is indicated.

[Intensified insulin therapy of type 2 diabetes mellitus: pre- or postprandial injection of aspart insulin?]. / Intensivierte Insulintherapie des Typ-2-Diabetes mellitus: Prä- oder postprandiale Injektion von Aspart-Insulin?

BACKGROUND AND OBJECTIVE: Intensified insulin therapy using rapid acting insulin analogues is advocated in younger type 2 diabetic patients at risk of developing diabetic complications. Most patients prefer postprandial insulin injections. So far, however, there were no data on glycemic control by postprandial aspart insulin in patients with type 2 diabetes. PATIENTS AND METHODS: To compare blood glucose responsiveness to preprandial vs. postprandial aspart injections, a randomised open intraindividual cross-over trial was carried out. Blood glucose was measured before and one hour after the three main meals and at bedtime. 18 insulin-naive patients with type 2 diabetes (age, 60 +/- 3 years (mean +/- SEM), known duration of the disease, 7 +/- 2 years) participated at this study. RESULTS: Both with preprandial and postprandial injections of aspart insulin, the averages of the 7-point blood glucose profiles (8.27 +/- 0.50 vs. 8.5 +/- 0.61 mmol/l) were similar. With postprandial aspart insulin, however, 84 % of the blood glucose levels measured one hour after breakfast exceeded > 10 mmol/l in comparison to 38 % with preprandial aspart insulin (p < 0.05). Patients injected similar amounts of basal and aspart insulin on both experimental days (insulin glargin, 11 +/- 3 U, aspart insulin, 23 +/- 2 vs. 25 +/- 2 U/day, p = 0.4843). CONCLUSION: Both preprandial and postprandial insulin aspart can be allowed to well-controlled type 2 diabetic patients. However, patients will benefit from the recommendation to inject insulin aspart immediately before meal if food with a high glycemic index such as the continental breakfast is to be consumed.

How useful are high vaginal swabs in general practice? Results of a multicentre study.

Vulvovaginal symptoms are a common reason for consultation with a general practitioner (GP). High vaginal swabs (HVS) are used to investigate symptoms, but their usefulness is poorly evaluated and microbiological tests performed vary between laboratories. In this multicentre study of 797 women with genital symptoms attending GPs, diagnostic yield of HVS was poor except for Candida spp. (22%). There is an urgent need to establish the most cost-effective approach for the management of these women.

Gonorrhoea in young heterosexuals attending urban STD clinics in Britain: a cross-sectional survey.

Young people in the UK bear the brunt of sexually transmitted infections, in particular of gonorrhoea. We aimed to assess whether young people with gonorrhoea (under 21 years) attending sexual health clinics differed from older individuals with gonorrhoea in their behavioural and clinical characteristics and management outcomes. The results of this cross-sectional study suggest that young people were more likely to be female (66.2% vs 34.1%), have concurrent infection with Chlamydia trachomatis (55.4% vs 30.2%) and a history of recent gonococcal infection (81.3% vs 35.5%) if they ever had gonorrhoea. Young women were more likely to experience treatment delay and not to attend for follow-up than older women. Resistance to ciprofloxacin was high in both age groups but the prevalence of penicillinase-producing Neisseria gonorrhoeae was higher in older patients (11.5% vs 1.3%). Different management protocols for young and older patients with gonorrhoea may need to be considered.

Is first trimester exposure to the combination of antiretroviral therapy and folate antagonists a risk factor for congenital abnormalities?

OBJECTIVES: To assess use of antiretroviral therapy (ART) by HIV positive pregnant women in London since 1994 and the risk of congenital abnormalities associated with multidrug exposure during the first trimester of pregnancy. METHODS: Retrospective multicentre study of medical, obstetric, and paediatric notes of all mother-infant pairs, where the mother was known to be HIV infected before delivery, using a standardised proforma. RESULTS: In this study of 195 mother-infant pairs, use of ART during any stage of pregnancy increased from 33.3% in 1994 to 92.5% in 1999 (p=0.01, trend). First trimester exposure increased from 0% in 1994 to 27.5% in 1999 (p=0.00045, trend). Congenital malformations were observed in nine infants (4.6%). Compared with infants not exposed to ART or folate antagonists during the first trimester (n=148), exposure to both ART and folate antagonists during the first trimester (n=13) was associated with an increased risk of congenital abnormalities (4% v 23.1%; OR 7.10, 95% CI 1.5, 34.2). No malformations were observed in the 34 children exposed to either ART or folate antagonists alone during the first trimester. CONCLUSION: An increasing number of HIV infected women conceived while on ART. Although there is no evidence of teratogenicity caused by ART if given alone during the first trimester, exposure to the combination of ART and folate antagonists was associated with a significantly higher risk of congenital abnormalities in this cohort.

[Intensified conventional insulin therapy in patients with type 2 diabetes mellitus. Positive long-term effects of insulin lispro on metabolic control and microalbuminuria]. / Intensivierte konventionelle Insulintherapie (ICT) bei Patienten mit Typ 2 Diabetes mellitus. Günstige Langzeiteffekte von Insulin Lispro auf Stoffwechselkontrolle und Mikroalbuminurie.

AIMS: It was decided to demonstrate by the present observations to which extent beneficial long-term effects on metabolic control, body weight and microalbuminuria can be attained by applying intensive insulin therapy (IIT) to type 2 diabetic patients, particularly when using insulin lispro. METHODS: In our observational study, clinical data were evaluated during 6, 12 and 36 months after participation in our structured inpatient insulin treatment and teaching programme in 25 patients with conventional insulin therapy (CT), in 10 patients with IIT using human normal insulin and in 15 patients with IIT using insulin lispro who all could be followed for 3 years in our outpatient diabetic clinic. RESULTS: In the CT-treated patients, HbA1c decreased from 10.2 +/- 0.4% to 7.6 +/- 0.2% (average +/- SEM) after 3 years. Body weight increased from 27.8 +/- 0.9 kg/m2 to 28.6 +/- 0.9 kg/m2, insulin dose increased from 29 +/- 3 U/day to 48 +/- 5 U/day (all p < 0.05), urinary albumin concentration was only transiently reduced. In the IIT-treated patients using human normal insulin, HbA1c fell from 10.6 +/- 0.8% to 7.9 +/- 0.5%, body weight increased from 27.8 +/- 1.4 kg/m2 to 29.8 +/- 1.3 kg/m2, urinary albumin concentration was reduced from 26 +/- 10 mg/l to 13 +/- 3 mg/l (all p < 0.05). Insulin dose increased only slightly from 57 +/- 6 U/day to 63 +/- 7 U/day. In the IIT-treated patients using insulin lispro HbA1c fell from 8.4 +/- 0.5% to 6.7 +/- 0.3%, body weight increased from 27.6 +/- 1.0 kg/m2 to 28.7 +/- 1.3 kg/m2, insulin dose from 36 +/- 5 U/day to 50 +/- 7 U/day, urinary albumin concentration was reduced from 23 +/- 4 mg/l to 13 +/- 4 mg/l (all p < 0.05). Blood pressure remained uninfluenced by insulin therapy. CONCLUSION: In our patients, we observed a beneficial long-term effect on metabolic control of IIT-treatment using insulin lispro, which was evident over the complete 3-year observation period, together with an only moderate increase in insulin dose and a clinically acceptable increase in body weight, but a remarkable reduction of microalbuminuria. Thus, clinical outcome was superior to that in patients treated with CT or IIT using human normal insulin.

Decreased fertility among HIV-1-infected women attending antenatal clinics in three African cities.

Population HIV prevalence estimates rely heavily on sentinel surveillance in antenatal clinics (ANCs), but because HIV reduces fertility, these estimates are biased. To aid interpretation of such data, we estimated HIV-associated fertility reduction among pregnant women in ANCs in Yaoundé (Cameroon), Kisumu (Kenya), and Ndola (Zambia). Data collection followed existing HIV sentinel surveillance procedures as far as possible. HIV prevalence among the women was 5.5% in Yaoundé, 30.6% in Kisumu, and 27.3% in Ndola. The birth interval was prolonged in HIV-positive multiparous women compared with HIV-negative multiparous women in all three sites: adjusted hazard ratios of pregnancy were 0.84 (95% confidence interval [CI]: 0.62-1.1) in Yaoundé, 0.82 (95% CI: 0.70-0.96) in Kisumu, and 0.74 (95% CI: 0.61-0.90) in Ndola, implying estimated reductions in the risk of pregnancy in HIV-positive women of between 16% and 26%. For primiparous women, the interval between sexual debut and birth was longer in HIV-positive women than in HIV-negative women in all sites, although the association was lost in Ndola after adjusting for age and other factors. Consistent results in different study sites help in the development of standard methods for improving ANC-based surveillance estimates of HIV prevalence. These may be easier to devise for multiparous women than for primiparous women.
