The rates of herpes simplex virus (HSV) infection are rising, the highest prevalence being in the group infected with the human immunodeficiency virus (HIV). We review the relation between these 2 infections. The presence of genital ulcers increases the transmission of HIV, and the presence of HIV adversely affects the natural history of HSV infection. The detection and treatment of sexually transmitted diseases such as genital herpes actually decrease the rates of HIV infection in groups studied. The treatment of HSV in persons with HIV is challenging because the incidence of immunosuppression increases. Acyclovir resistance is more common in this group, but acyclovir use may prolong survival in some HIV-seropositive patients. Further studies are needed to determine whether persons with HIV disease should routinely be given HSV-specific therapy.

Alpha-herpesvirus infections by herpes simplex virus and varicella-zoster virus among HIV-infected patients were summarized. These infections were occurred in a high frequency and shown to be extensive lesions, prolonged virus excretion from the lesions, generalized infection, and uncommon diseases as compared these of with immunocompetent patients. Acyclovir-resistant viruses appeared. These evidences supplied the profound understanding of the pathogenesis and new subjects in the field of herpesvirus infection. Recent introduction of HAART against HIV and the appropriate use of anti-herpesvirus drugs, however, reduced the development of severe infection, and provided successful treatment, respectively.

The most common therapies against human herpes virus (HSV-1) and human immunodeficiency virus (HIV-1) infectivity are based on the administration of nucleoside analogues. Acyclovir (ACV) is the drug of choice against HSV-1 infection, while the acyclic nucleoside phosphonate analogue PMPA has shown marked anti-HIV activity in a phase I and II clinical studies. As monocyte-derived macrophages are assumed to be important as reservoirs of both HSV-1 and HIV-1 infection, new approaches able to inhibit replication of both viruses in macrophages should be welcome. ACVpPMPA, a new heterodinucleotide consisting of both an antiherpetic and an antiretroviral drug bound by a phosphate bridge, was synthesized and encapsulated into autologous erythrocytes modified to increase their phagocytosis by human macrophages. ACVpPMPA-loaded erythrocytes provided an effective in vitro protection against both HSV-1 and HIV-1 replication in human macrophages.

The purpose of this study was to determine the frequency of HSV infections and recurrences among HIV-infected patients and to examine different regimens for suppression of HSV recurrence. A randomized retrospective chart review of HIV-infected patients at a public hospital in Los Angeles County was conducted. We reviewed 224 patients' charts; 26 percent had AIDS based on the 1987 CDC definition. HSV infection was documented as a clinical event in 51 records (23 percent). Patients with an AIDS diagnosis had a greater incidence (53 percent) of HSV infections than did those with a diagnosis of symptomatic or asymptomatic HIV infection (p < 0.001, Fisher's exact test). Recurrences of HSV occurred in 26 (51 percent) of the 51 HSV-infected persons during a period of 1042 patient months. Eighteen patients who had received acyclovir suppression at 600 mg/day had three HSV recurrences in 382 patient months, whereas 14 who received 400 mg/day had eight recurrences in 282 patient months (p = 0.02). HSV infections occur in 23 percent of HIV-infected patients, increasing to 53 percent in AIDS patients. Acyclovir suppression prevents recurrent HSV, and a dosage of 600 mg/day is more effective than 400 mg/day.

The virus that causes genital herpes affects 20 percent of the World's population. Among people with HIV, the incidence may be as high as 90 percent. All herpes viruses are formal candidates for the cofactor effect promoting HIV infection. People with unrecognized disease may account for many new cases. Only 20 percent of herpes seropositive persons recognize their herpes symptoms, 60 percent have unrecognized symptomatic disease, and 20 percent have subclinical, asymptomatic shedding of virus. Acyclovir shows promise of being effective in reducing herpes transmission, however, people with herpes should abstain from all sexual activity during symptomatic outbreaks, and at all other times use some sort of barrier protection. Acyclovir, in combination with AZT, is associated with survival benefits for people with AIDS, but new generations of antivirals may prove more effective in treating herpes. A post-infection vaccine, several of which are in development, may be even more promising.

Herpes is caused by a virus that causes recurring bouts of cold sores or genital lesions. The differences between herpes simplex virus 1 (HSV-1) and herpes simplex virus 2 (HSV-2) are explained. Herpes outbreaks can become harder to treat when the immune system is damaged by HIV. Acyclovir and famciclovir are safe and effective treatments, but preventing infection is especially important in HIV-infected individuals, as the amount of HIV in the blood increases during a herpes outbreak. World Wide Web addresses are provided for alternative herpes treatment information. A current trial is studying the effectiveness of acyclovir used with an antiviral gel, SP-303. Participants will be treated with acyclovir alone or with acyclovir and SP-303 gel. Call the Network for referral information.

Genital herpes is one of the most widespread sexually transmitted diseases in the world. HSV2 predominates (60-80 p. 100), but the prevalence of HSV1 genital herpes is rising (20-40 p. 100). Erosive lesions of the genital organs due to HSV infection are a factor favoring HIV contamination and other sexually transmitted diseases. The main factor of transmission is asymptomatic viral excretion. Aciclovir, valaciclovir and famciclovir are effective treatment for genital herpes (primary infection, curative and preventive treatment of recurrence), but none of these compounds alters the natural history of the infection. Aciclovir given as a preventive measure reduces the load of asymptomatic viral excretion. Information and education of patients with genital herpes are key elements for prevention. Use of preservatives appears to be effective. New vaccine strategies favoring humoral and cellular response should be studied.

The World Health Organization clinical criteria for AIDS diagnosis in Africa include Kaposi's sarcoma, Herpes zoster, Herpes simplex, and pruritic maculopapular rash, which have a predictive value for HIV seropositivity of 71-98%. Skin conditions may be classified as: 1) generalized dermatitis, 2) bacterial, fungal, viral, and parasitic infections, and 3) skin tumors. Pruritic maculopapular rash (prurigo) is often the first outward sign of HIV infection. Soothing preparations such as calamine lotion or E45 emollient cream can be applied. Occasionally antihistamine may be necessary, e.g., 10 mg of chlorpheniramine 8 hourly. Skin lesions may become secondarily infected with bacteria; usually Staphylococcus aureus and Streptococcus species. Persistent folliculitis or carbuncles should be treated with flucloxacillin 250 mg QDS for 7 days. In HIV/AIDS fungal infections often develop secondary infection. Candidiasis (thrush) is caused by yeasts, mainly Candida albicans and a small percentage by Tolurosis glabrata. Many HIV-infected patients suffer from seborrheic dermatitis. Fungal diseases more typically present as ringworms of the scalp (Tinea capitis). Whitfield's ointment is effective for ringworm. Antifungal creams such as miconazol or clotrimazole and systemic antifungal tablets such as ketoconazole, fluconazole, and itraconazole are also effective. Gentian violet lotion twice daily and Acyclovir tablets, 200 mg 5 times daily for 5 days, may help to reduce secondary Herpes simplex infection. HIV has been associated with an increased incidence of Herpes zoster (shingles). It is often necessary to give analgesics like aspirin or paracetamol to control the pain. Gentian violet paint may help to prevent secondary infection. When shingles affects the eye, Acyclovir tablets (800 mg 5 times daily) should be given. Kaposi's sarcoma affects wider age groups, and it is disseminated and more aggressive than the endemic type. Treatment options include radiotherapy and systemic cytotoxics such as vincristine. Intralesional injections of the drug interferon have also given successful results with some patients.

Extensive reviews of pulmonary infections in AIDS have reported few herpetic infections. Generally these infections are due to Herpes simplex type 1. Pneumonia due to herpes type 2 is extremely rare. We describe a 40 year-old HIV positive woman who complained of fever, cough and dyspnea for seven years. She had signs of heart failure and the appearance of her genital vesicles was highly suggestive of genital herpes. Echocardiography showed marked pulmonary hypertension, right ventricular hypertrophy and tricuspid insufficiency. After a few days of hospitalization she was treated with Aciclovir and later with Ganciclovir. An open pulmonary biopsy revealed an interstitial inflammation, localized in the alveolar walls. Some pulmonary arteries had widened walls and focal hyaline degeneration. Immunohistochemistry indicated that the nuclei had herpes simplex virus type 2 in many endothelial cells (including vessels with widened walls), macrophages in the alveolar septa and pneumocytes. There was clinical improvement after treatment for herpes. We concluded that as a consequence of herpes infection, endothelial involvement and interstitial inflammation supervene, with thickening of vascular walls and partial obliteration of the vessel lumen. A direct consequence of these changes in pulmonary vasculature was pulmonary hypertension followed by heart failure.

Forty-three consecutive cases of acute aseptic meningitis (AAM) presenting within a 24-months period were retrospectively analysed with respect to clinical symptomatology, cerebrospinal fluid (CSF) findings, clinical course, treatment and outcome. Nineteen of the 43 AAM cases (44%) were caused by enterovirus, one by HIV (2%), two by Varicella zoster virus (5%), three due to herpes simplex virus I (7%), two due to herpes simplex virus II (5%), one due to Central European encephalitis virus (2%), and in 15 patients (35%) the aetiology of AAM remained unknown. Headache (100%) and fever (93%) were the presenting symptoms in the majority of cases. Signs of preceding infection were predominantly gastrointestinal in the enterovirus subgroup, but were inconsistently observed in the other subgroups. CSF findings at the first lumbar tap on admission generally revealed lymphomonocytic pleocytosis of less than 500 cells per micro l, mild to moderately elevated protein and normal lactate and glucose levels. Initial therapy consisted of an empirical antiviral and antibiotic regimen until a serological diagnosis was available. Acyclovir, effective only in herpes family viruses, was initially administered to all AAM cases. Effective therapy for other viral pathogens are not broadly available and treating AAM of unknown aetiology imposes a particular problem. The average hospitalization time ranged from 16 to 31 days. Patients were either discharged home (72%) or transferred to a rehabilitation centre (28%). The outcome was good (40%) to fair (51%) in the majority of cases.
