Three patients with HIV-associated Kaposi sarcoma were treated with human recombinant granulocyte colony stimulating factor (G-CSF). They had all developed leucopenia during treatment with recombinant interferon-alpha-2a, in two cases combined with vincristine. In all three patients, there was an obvious rapid stimulation after s.c. injection of 300 or 150 micrograms G-CSF per day; the white blood count reached normal values within only a few days and partial transformation to leucocytosis took place. After discontinuation of G-CSF, leucocyte counts regressed rapidly to pretreatment levels. A dose of 150 micrograms of G-CSF twice to three times per week proved to be sufficient to keep the white blood cell count in the normal range allowing the treatment necessary for Kaposi sarcoma. G-CSF therapy had no serious side effects. One of the patients developed a tumour-like infiltration in his left upper jaw, which histologically simulated Burkitt's lymphoma and which regressed spontaneously after discontinuation of the G-CSF therapy. G-CSF plays an important role in the treatment of patients with HIV-associated Kaposi sarcoma and enables combined treatment with zidovudine, interferon, and cytostatic drugs.

For reasons not yet known HIV infected patients in the final state of their aids disease often tend to develop Kaposi's sarcoma. These tumours result in secondary lymphatic edema which is found on both sides of the sarcoma up to the regional lymphatic nodes, transferred by the tumour cells. Depending on the state of the edema, a lymph drainage treatment is indicated palliatively; the patients can thus be relieved. A fundamental deterioration of the prognosis is not to be expected, the more as all patients are in the final state of this not yet curable disease. Differing from treatment of other lymphatic edema, it is of special importance to the therapist--apart from the difficult and specifically psychic burden--to pay attention to a protection from infection by gloves as a precaution for each single treatment.

Clinical and paraclinical experience in HIV infection, though the time elapsed since the first observations is relatively short, begins to get typical outlines. In the case of AIDS, the lung is the main place of opportunistic infections, other inflammatory processes and neoplasia. The present work deals with six clinical cases with positive serum tests for HIV and secondary respiratory phenomena such as: Kaposi sarcoma, pneumonia with Pneumocystis carinii, tuberculosis, candidosis, pneumonia with common germs. Particular aspects of treatment and disease evolution are commented.

The first AIDS patient was a homosexual male who contacted HIV infection in 1982 in Tanzania. In December 1985 the first sign of Kaposi's sarcoma was noted in this patient. HIV infection was diagnosed in him only in February 1987. He was treated with AZT, reaferon, immunoglobulin and underwent electronic therapy. His state of health was stable till February 1991. Then he got severe bacterial pneumonia, candidosis. Pancytopenia progressed. The dose of AZT (0.8 g daily) was increased and intensive antibiotic therapy and the course of diflucan were prescribed. In spite of this treatment the number of CD4 lymphocytes catastrophically decreased (CD4 = 0.01 x 10(9)/l) and the patient died. Thus, more than 63 months passed from the date of the appearance of the first symptoms of AIDS in the patient to his death.

This article presents a case of gingival Kaposi's sarcoma that initially mimicked an acute periodontal infection, but was the first clinical sign of HIV infection in a 38-year-old male homosexual patient. The clinical features and treatment of oral Kaposi's sarcoma are discussed and the variable histopathology of the lesion is demonstrated.

Between January-June 1989, researchers evaluated 473 admissions and 100 deaths at the Pulmonary Medicine Service at the University Hospital in Abidjan, Ivory Coast to determine prevalence of HIV-1 and HIV-2 infections, to look at death rates in relation to HIV status, and to examine the pulmonary pathology associated with these infections compared with deaths in HIV negative patients. HIV-1 seroprevalence was 38%, HIV-2 4%, and dual HIV reactive 14%. The death rate for the entire sample was 21%. It was higher in HIV seropositive patients than HIV seronegative patients (27% vs. 14%; relative risk=1.95 times). HIV seropositive patients regardless of HIV group essentially died from the same diseases: 40% from pulmonary tuberculosis (disseminated nonreactive multibacillary pattern), 34% from nonspecific pneumonia, 8% from Pneumocystis pneumonia, 6% from Kaposi's sarcoma, and 4% from lung cancer. Among only HIV-1 seropositive cases, Pneumocystis carinii was the cause of death in only 95 of cases. The leading causes of death for HIV seronegative patients included lung cancer (64%), nonspecific pneumonia (28%), and pulmonary tuberculosis (4%). Researchers should be pressed to develop more sensitive means to diagnosis tuberculosis as well as prophylaxis against reactivation of tuberculosis among HIV seropositive people in Africa. Since Pneumocystis carinii infection is uncommon among HIV seropositive people in Africa, prophylaxis for it is not needed.

160 HIV-infected Greek patients were prospectively examined and the oral signs and symptoms recorded. At the time of oral examination, 76 patients were asymptomatic seropositive, 47 were in the ARC stage, and 37 had AIDS. 1 or more oral findings were recorded in 90.6% of the patients, while a total of 33 different lesions were observed. The more common oral lesions (highly suspicious) were candidiasis (61%), hairy leukoplakia (24%), periodontitis (19%), necrotizing gingivitis (11%), and Kaposi's sarcoma (12%). In addition, some unclassified lesions or symptoms (xerostomia--26%, burning mouth syndrome--19%, patchy depapillated tongue--16%, hairy tongue--10%, exfoliative cheilitis--4%) were common, while submandibular and cervical lymph node enlargement were found in 49% of the patients. It is interesting that in 16 patients (10%), the suspicion of HIV infection was based exclusively on oral lesions. The authors' findings show that oral signs and symptoms are common and occasionally early manifestations of HIV infection, and it is in association to those reported in previous studies.

A new case of supratentorial malignant glioma is reported in an HIV-1 infected male homosexual. Tumours of the nervous system account for only 5 to 10 percent of neurological complications of AIDS, and most of them are lymphomas or metastases from Kaposi's sarcomas. In fact, HIV-1 is a neurotropic lentivirus, not transforming by definition. Our patient had a frontal tumoral syndrome resistant to the conventional anti-toxoplasmic treatment. Pathological examination of a tumoral fragment obtained by stereotactic biopsy showed that according to the WHO criteria the tumour was a glioblastoma. The mechanism through which HIV infection results in malignant transformation of astrocytes is conjectural. There is no consensus on whether the virus is located in glial cells, but the transgenic animal technique suggests that the tat gene might play a certain role. Other hypotheses concerning the indirect neurotoxicity of HIV have been put forward, notably that of viral coinfection with viruses of the papova group.

Verrucous skin lesions have been attributed to various herpes viruses in immunosuppressed patients, including those with human immunodeficiency virus infection (HIV). We examined such lesions from six HIV-infected patients to determine the range of microscopic findings present and to establish which herpesviruses were present. Verrucous epidermal hyperplasia, pseudocarcinomatous hyperplasia, and massive hyperkeratosis correlate with the warty clinical appearance of the lesions. Herpetic cytopathic changes, including multinucleated epidermal giant cells, steel-gray nuclei, necrotic acantholytic keratinocytes, and Cowdry type A nuclear inclusions were seen most prominently in the dells between papillations and in adnexal epithelium. In two cases, increased numbers of spindled cells were seen in the dermis. Immunoperoxidase staining with anti-type IV collagen antibodies demonstrated that these findings were not those of Kaposi's sarcoma, but represent a fibrotic reaction to the infection. Viral cultures of four of the cases demonstrated the presence of varicella-zoster virus, whose presence was detected by the polymerase chain reaction in paraffin-embedded lesional tissue from all six cases. Polymerase chain reaction did not show the presence of cytomegalovirus, herpes simplex, Epstein-Barr, or human papillomavirus. We conclude that these unusual verrucous lesions are a chronic manifestation of herpes zoster infection and that the reported presence of other agents in such lesions is probably coincidental.

We report the detailed clinical features of discrete mass lesions of the gastrointestinal tract caused by cytomegalovirus in three patients who had the acquired immunodeficiency virus syndrome. The disease occurred in the fundus of the stomach in one patient and in the cecum in the other two persons. The symptoms as well as radiographic and endoscopic findings in each case are described and are shown to be indistinguishable from those resulting from a neoplasm. The diagnosis was established by the presence of inflammation with cytomegalovirus-like inclusions and confirmed by immunoperoxidase staining. Cytomegalovirus infection should be considered, along with Kaposi's sarcoma and lymphoma, as a cause of focal mass lesions of the alimentary tract in persons infected with HIV.
