    The effect of excess phosphorus vapor during the process of MIS structures on InP is analyzed in detail. It is shown that the density of interface state distribution is considerably modified after in situ thermal precleaning of the substrate in phosphorus overpressure (suppression of the Fermi-level pinning and significant reduction of the density of surface states near midgap). Phosphorus overpressure also provides an efficient protection of the surface during the insulator deposition. Fermi-level pinning in the upper part of the gap is assigned to the uncontrolled native oxide left on the surface after a stay of InP substrate in ambient atmosphere.

    Notes:
    Two passivation treatments of InP surface are presented: (i) thermal treatment under an arsenic partial pressure by molecular-beam epitaxy technique, and (ii) a new As-based aqueous chemical treatment. Both result in similarly improved electronic and physicochemical properties of the InP surface. The fast interface state density is reduced, the drift phenomena are practically suppressed and the thermal stability is greatly enhanced.

    Summary A combination of oral zidovudine (250 mg twice daily) and subcutaneous interferon-alpha (10×106 units daily) was evaluated for clinical, antiretroviral, and immunological efficacy and for side effects in 17 patients with AIDS-related Kaposi's sarcoma. Fifteen patients were evaluable. During the study period of 12 weeks, tumor responses were complete in two patients and partial in two patients (27% major response rate). Minimal responses were seen in two patients (40% overall response rate). An anti-HIV effect (reduction of serum p24 antigen by 70% or more) was observed in seven of ten evaluable patients who were initially antigenemic. CD4 lymphocyte counts remained unchanged. In six patients who had either a tumor response or a marked decline of HIV antigenemia, the treatment was continued between 12 and 59 weeks beyond the study period. Two of four patients with tumor regression at 12 weeks had an additional tumor response in this period despite prior dose reduction of interferon due to toxicity. Late progression of KS was eventually observed in four of six patients on prolonged treatment. The responsiveness of Kaposi's sarcoma seen in this study in patients with low CD4 counts and prior constitutional symptoms (fever, weight loss) was unexpected and needs further confirmation by larger patient groups. Dose-limiting toxicities were bone marrow depression (severe anemia in four and neutropenia with anemia in two patients), subjective adverse experiences (fever, fatigue, myalgia; four patients) and both (two patients). Adjustment of the interferon dose improved the subjective as well as the hematologic tolerance to the combined treatment. Thus, the combination of zidovudine and interferon-alpha can be considered as a possible treatment of AIDS-related Kaposi's sarcoma. However, its use may be limited by toxicity.

    Notes:
    Abstract The seroprevalence of latentToxoplasma gondii infection was determined in a cohort of 715 HIV-positive patients followed up at an HIV outpatient clinic. Using indirect immunofluorescence and direct agglutination assays for detecting IgG, the prevalence of anti-Toxoplasma gondii antibodies was shown to be 50 %. During a four-year period, clinically apparent acute toxoplasmosis occurred in 47 patients (43 with cerebral, 3 with ocular and 1 with bone marrow toxoplasmosis) among the 360 patients positive for anti-Toxoplasma gondii IgG and in one patient (with cerebral toxoplasmosis) among the 355 patients who were serologically negative. A significant rise in IgG levels could be shown during acute toxoplasmosis episodes in only 30 % of patients, compared with 3 % of patients without active toxoplasmosis. During acute toxoplasmosis, IgM antibodies were detected in only two patients (6 %) by an immunosorbent agglutination assay and in one (3 %) by an enzymatic immunocapture assay. Specific IgA was detected by a non-enzymatic immunocapture assay in six patients (18 %) during acute episodes. The very high predictive value (99.7 %) of a negative IgG test remains the best serological parameter for excluding an acute episode of toxoplasmosis in HIV-positive patients.

    Notes:
    Abstract Over a three-year period, 54 episodes of pneumonia were diagnosed in 45 adults infected with the human immunodeficiency virus (HIV). These episodes were reviewed in order to assess the distribution of pathogens and their clinical presentation. Thirty-six episodes were due to an opportunistic pathogen (Pneumocystis carinii in 31,Mycobacterium avium complex in 3,Mycobacterium tuberculosis in 2), and 18 were caused by non-opportunistic pathogens (11Streptococcus pneumoniae, 2Haemophilus influenzae, 5 unknown pathogens that responded to broad-spectrum antibiotics). Non-opportunistic pneumonias were characterized by an abrupt onset (18/18 had pulmonary symptoms of 〈 7 days duration), high fever (13/18), and focal lung infiltrates (17/18). In contrast, opportunistic infections infrequently presented with pulmonary symptoms of 〈 7 days duration (3/36) or high fever (7/36), and most of the chest radiograms (34/36) disclosed a diffuse lung infiltrate. In HIV-infected patients presenting with pneumonia, simple clinical and radiological data may point to bacterial pathogens. Such data could be used in selected cases to spare invasive procedures and to start empirical antibiotic therapy.

    Notes:
    Abstract Twenty-five patients seen consecutively at an HIV outpatient clinic who had clinical evidence of oropharyngeal candidiasis and two or more oral swabs positive for yeasts on culture were studied retrospectively. For each of the 65 isolates susceptibility to fluconazole was evaluated by the disk diffusion test and determination of the minimal inhibitory concentration (MIC). A correlation was sought between clinical resistance and in vitro susceptibility data. Seven patients were non-responders and 19 were responders (one patient figuring in both groups). Significant differences were observed between the two groups with respect to the median interval after the diagnosis of AIDS (27 months in non-responders and 2 months in responders; p=0.001), the median CD4+ cell count (6 and 21 cells/mm3 respectively; p=0.005) and the median number of previous episodes of oropharyngeal candidiasis treated with fluconazole (13 and 2 episodes respectively; p=0.001).Candida albicans was identified in 64 of 65 cultures. The correlation between MIC values and diameters of inhibition was good (r=0.85; p〈0.001). The degree of in vitro susceptibility of the isolates to fluconazole showed a significant difference between non-responders and responders (mean inhibition diameters 13 and 36 mm respectively; p〈0.001) with a tentative cut-off value of 25 mm. An advanced stage of HIV infection and previous exposure to fluconazole could be risk factors for the development of fluconazole-resistant oropharyngeal candidiasis.Candida albicans strains with decreased in vitro susceptibility to fluconazole were responsible for the clinical resistance which could be predicted by a simple disk diffusion test.
