Retrospective analysis of medical records of 557 HIV positive patients (including 113 with AIDS) revealed 17 patients with an antemortem clinical diagnosis of cytomegalovirus (CMV) disease. This group comprised 7 injection drug users (2 male and 5 female) and 10 homosexual men. Males were significantly older than females, and homosexual men were significantly older than drug users at the time of diagnosis of CMV. All 17 patients had evidence of retinitis, and 6 also had evidence of extraocular disease. CMV retinitis was the AIDS defining diagnosis in two patients, and the attack rate of CMV in all AIDS patients progressively increased with time, with a 3-year CMV-free survival of 57%. Fifteen patients with CMV disease had evidence of previous CMV infection (CMV IgG positive), with 7 also having a positive CMV IgM and 10 a positive viral culture. The mean CD4+ lymphocyte count at diagnosis of CMV was 17 cells/mm3, compared with 68 cells/mm3 at diagnosis of AIDS. Therapy was unsatisfactory, often being complicated by marrow suppression. Relapse occurred in 11 patients after initial improvement but despite this only 3 patients died with severe visual impairment. The mean survival after a diagnosis of CMV was 10.5 months. This study confirms that disease caused by CMV is usually a late manifestation of AIDS, and the increasing prevalence among patients with AIDS implies that, the longer the survival, the greater the risk of disease. Frequent fundoscopy in HIV positive patients is of paramount importance particularly in patients who have a CD4+ lymphocyte count of less than 100 cells/mm3.

We analysed the correlation between ophthalmic and systemic findings in 125 subjects with AIDS and 50 subjects with AIDS-related complex (ARC). Positive eye findings were defined as the presence of cotton-wool spots (CWS) or cytomegalovirus (CMV) retinitis. The presence of positive eye findings was significantly more frequent in AIDS than in ARC (P = 0.0001). Both lowest haematocrit and lowest T-helper cell count were significantly lower in AIDS than in ARC, and also lower in subjects with positive eye findings than in those with negative eye findings. No association was found between ocular findings and the following: risk factors for human immunodeficiency virus (HIV) transmission; positive titres for CMV, herpes simplex, Epstein-Barr virus (EBV), and toxoplasmosis; systemic infections; and intake of azidothymidine (AZT). Patients with AIDS and CWS were similar to patients with AIDS and CMV retinitis in viral serology, haematocrit, T-helper count, and survival. Positive eye findings, low haematocrit, and low T-helper count are poor prognostic signs for survival in AIDS.

The two major risk groups for acquisition of HIV in the UK are gay men and IDUs. Individuals from these risk groups vary in a number of respects in their life-style, which have the potential to affect the course of their HIV disease. This study compares gay men and IDUs from the Lothian Region of Scotland with respect to their AIDS defining diagnosis and subsequent CDC (Centers for Disease Control) stage IV events. Comparisons were made between the two risk groups for their AIDS defining diagnosis by performing chi square tests, Mann-Whitney tests and logistic regression. Subsequent CDC stage IV events were analysed using ordinal logistic regression and Cox regression. 89 IDUs and 56 gay men were included in the analysis. Oesophageal candida was a commoner AIDS-defining diagnosis in IDUs than gay men and Kaposi's sarcoma was diagnosed more frequently in gay men than IDUs. Subsequently oesophageal candida was also commoner in IDUs and CMV retinitis was seen more frequently in gay men. The role of prophylaxis and differences in diet are discussed as possible causes of the observed differences in the incidence of oesophageal candida. The higher incidence of CMV retinitis in gay men probably reflects the high level of sexual acquisition of CMV.

Cytomegalovirus (CMV) is a non-pathogenic organism in the immunocompetent, but is a major cause of morbidity and mortality amongst patients with AIDS, and the retina is the commonest site of infection. If left untreated, patients with CMVR will develop disease in their second eye and ultimately become blind. However, with correct diagnosis and treatment useful vision can be maintained in the majority of cases. Fifteen to 20% of patients with AIDS will contract cytomegalovirus retinitis (CMVR) and this may be the AIDS-defining diagnosis though more commonly it occurs months after the diagnosis of AIDS. Given the increasing number of HIV positive patients and their longer survival, it is likely that CMVR will become an increasingly prevalent condition. In these patients loss of sight from CMVR has devastating consequences in terms of loss of independence and quality of life and therefore ophthalmologists and physicians should be aware of the presenting characteristics of CMVR, be familiar with therapy and its complications, and be able to recognize relapsing infection.

The medical records, retinal drawings and fundus photographs of all patients with cytomegalovirus retinitis (CMVR) and AIDS in Edinburgh between 1986-1992 were reviewed to determine the efficacy of treatment in preserving vision. Ophthalmoscopic features of CMVR were observed in 32 eyes of 24 patients with AIDS, 19 males and 5 females. HIV transmission in this group was by homo/bisexual contact (16), injection drug use (7) and blood transfusion (1). Unilateral blurring was the commonest visual symptom although 9 (38%) patients had no visual symptoms. All patients presented with a corrected visual acuity of 6/12 or better in at least one eye. Following treatment with systemic ganciclovir or foscarnet 16 patients (66%) developed toxic side-effects of therapy and 13 (54%) experienced a recurrence of CMVR. Four (17%) patients developed a retinal detachment in one eye. The mean survival was 8.3 months after the diagnosis of CMVR. At final follow-up, between 2-26 months after the diagnosis of CMVR, 21 (87.5%) patients retained useful vision (6/18 or better) although 3 (12.5%) were effectively blind (less than 6/60). We conclude that with prompt diagnosis and treatment of CMVR vision can be preserved in the majority of cases.

Cytomegalovirus retinitis is a major cause of morbidity in patients with AIDS. The conventional treatment approach has involved insertion of a central venous catheter and intravenous administration of ganciclovir and/or foscarnet. This has been associated with systemic toxicity, line-related sepsis, and implications for patient quality-of-life. An oral formulation of ganciclovir has now been licensed for use as maintenance therapy in CMV retinitis. Multicentred trials comparing oral and intravenous ganciclovir have suggested that although the efficacy may be marginally reduced with the oral formulation, the associated toxicity is significantly lower. With careful and informed decision-making by both clinician and patient, the opportunity exists to enhance the quality of life in this patient group.

A novel form of therapy, the intravitreal ganciclovir implant (Vitrasert), was used to treat cytomegalovirus (CMV) retinitis in AIDS, when it was not possible to continue systemic therapy or disease progression was evident despite conventional intravenous treatment. A review of the ophthalmic and general health data, operative records and fundus photographs of 9 individuals who had Vitrasert implantation surgery in Edinburgh. Two patients received bilateral replacement implant procedures. Visual acuity, concomitant anti-CMV therapy, complications of implantation and control of retinitis were documented until final follow-up. Control of CMV retinitis was achieved in all individuals at one month postoperatively and remained controlled for a mean period of 5.8 months. Postoperative complications were mild and transient in all but 2 eyes of 2 patients who developed non-progressive macula oedema. Blinding complications as a result of surgery were not encountered and retinal detachment was not observed in this series. Vitrasert implantation is an acceptable and well tolerated treatment for CMV retinitis when systemic therapy fails to control disease progression.

We aim to assess the usefulness of the cytomegalovirus (CMV) pp65 antigenaemia test, also called the CMV direct antigen test (DAT), in the management of patients with advanced human immunodeficiency virus (HIV) infection; we studied all patients who had pp65 assays between 8 September 1995 and 30 August 1996. Twenty-three patients had 31 tests. The mean CD4 cell count was 20/mm3. The tests were negative in 16 patients, of whom 12 have not developed CMV end-organ disease after a mean follow up of 114 days (range 14-269 days), whilst the remaining 4 patients had previously treated CMV disease. Eleven patients had positive tests: 4 had active CMV disease, 2 subsequently developed CMV retinitis, 2 died within a fortnight of multi-drug resistant tuberculosis (MDR-TB), one was lost to follow up and 2 have remained disease-free. This test has a positive predictive value of 43% and a negative predictive value of 94%, Fisher's exact test P=0.03. The pp65 antigenaemia assay can be performed in a standard virology laboratory avoiding the problems associated with polymerase chain reaction (PCR), a result is available within 5 h, and it is semi-quantifiable. However, a large prospective study is required to determine the comparative value and roles of the pp65 antigenaemia assay and DNA PCR in the management of CMV disease, especially with regard to the use of primary prophylaxis and pre-emptive therapy.

This report studies the accuracy of conjunctival swab polymerase chain reaction (CS-PCR) for the diagnosis of human cytomegalovirus retinitis (HCMV) in AIDS patients. PCR and virus culture were used for the detection of HCMV in conjunctival swab, serum, and urine specimens from 38 AIDS patients between April 1996 and April 1998. The clinical utility of the identification of HCMV retinitis by these 6 different methods was demonstrated by their prediction power to estimate AIDS patients at risk of contracting HCMV retinitis. The sensitivity, specificity, positive predictive value, and negative predictive value of CS-PCR for the detection of HCMV retinitis were 91.5%, 80.9%, 60.8%, and 92.7%, respectively; for serum PCR were 74.3%, 81.7%, 57.2%, and 90.3%; for urine PCR were 100%, 17.3%, 20.4%, and 100%; for conjunctival swab culture were 22.7%, 100%, 100%, and 86%; for serum culture were 27.3%, 98.1%, 75%, and 86.4%; and for urine culture were 90.9%, 44.2%, 25.6%, and 95.8%.

A study on AIDS subjects carried out at the Calmette Hospital in Phnom-Penh between the 1st January 97 and the 30th December 98. The objective of this study was to describe the most frequent clinical manifestations as well as the opportunistic infections according to the 1993 CDC classification (purely clinical classification). Three hundred and fifty six AIDS patients hospitalized in medicine B were included in our study. A complete file was prepared for each subject, specifying his/her social and family situation, profession, sexual behavior and history. The clinical condition was specified and the paraclinical examinations were recorded. The average age was 35 years with 250 men and 106 women, i.e. a M/F sex ratio of 2.4. The majority of male contaminations were due to sexual relationships with multiple partners, 82%, and women with a single partner was of 78%. The use of condoms was of 60% (versus 40% occasional); the extent of drug-addiction was 1.12% (4 cases). A history of STD was found in 56% of cases. The presenting symptoms most frequently found were asthenia, anorexia, fever and weight-loss. In decreasing order, the clinical manifestations often associated were: weight-loss > 10% or a catechetic condition 58.70% (209/356), fever > 38 degrees C >1 month 53% (189/356), diarrhea (> one month) 41.60% (148/356). The most frequent opportunistic infections were: oral candidiasis 51.40% (183/356) and 40% are oro-oesophageal (oral candidiasis + dysphagia or odynphagia), pulmonary and extrapulmonary tuberculoses (TB) 43.50% (155/356) (pulmonary TB in 65.16%, TB of the lymph nodes 23.22% and disseminated TB and cerebral TB 11.61%), cryptococcal meningitis 11.80% (42/356) and pneumocystosis 6.50% (23/356), CMV retinitis 1.12% (4/356). The other opportunistic manifestations such as toxoplasmosis and Kaposis sarcoma are much more rarely encountered due to the difficulties of the paraclinical diagnosis. The mortality in the department was of 17.40% (62/356). In conclusions, tuberculosis is the most frequent of the opportunistic infections in Cambodia. Cryptococcal meningitis is in 3rd place for opportunistic infections. It is the first diagnosis that should be evoked in a meningeal irritation.
