Current status of HIV infection around the world suggests the following: Screening HIV antibodies in blood donors is the most promising for the prevention of transfusion associated infections. Besides blood donor screening, the availability of blood tests to be taken anonymously is essential for controlling silent or occult HIV infection. Red cell transfusion therapy with CR 1 rich erythrocyte for AIDS patients is also promising. In the US transfusion associated HIV infection decreased from 1988 to 1989 by 12% in adults and 39% in children, while that associated with other risk factors such as homosexual acts and IV drug use continued to increase. Rate of HIV antibody positive donors also decreased from 0.13 in 1985 to 0.013% in 1988 owing to education, counseling and screening. Surveillance for HIV-2 continues although no case was found during 1987-1989 investigations. as of 1989, the highest rate of AIDS patients in Europe was in France followed by Italy, Spain and Germany. HIV antibody positive donors drastically decreased in those countries from 0.062 in 1985 to 0.012 in 1989. In contrast, Eastern European nations have shown significant increases. Table II shows rates of HIV-1 and HIV-2 positive donors in Africa. In Asia 843 AIDS patients were recorded at the end of 1990. IV drug use and prostitution were main factors. HIV positive rate among 30 million tested in Japan since 1987 was 0.00018%. HIV antibody positive rate was 0./000487%, the highest rate being found in the Tokyo area. Transfusion therapy with CR 1 (c3b receptor) rich erythrocytes given every 2 months to 9 patients of carinii pneumonia resulted in the survival rate of 5.9 for more than 15 months, compared with 2/20 for 12 months for those who had occasional blood transfusions. Controls who received no transfusion therapy all died within 10 months. In 1990 heterosexuals are also found to be affected in Japan mostly through infected prostitutes.

Bronchoalveolar washout was performed in 130 patients with pneumonia during a period of 28 months. Microbiological investigation involved common bacteria, Legionella, fungi, viruses (Cytomegalovirus, herpes, RSV), Mycobacterium, and Pneumocystis carinii. Infection HIV was present in 75% of patients. The remaining patients had malignant diseases or severe pneumonia. The overall sensitivity of the technique was 65.4% and the positive predictive value was 92%. The technique was less sensitive in cases of bacterial pneumonia (sensitivity = 34.4%). This was attributed to the fact that 82.8% of these cases received antibiotic therapy. Pneumocystis carinii and Mycobacterium tuberculosis were the most common agents (44.8% and 34.5%, respectively). In seven instances the clinical picture was related to cytomegalovirus, although this diagnosis can not be easily done.

The value of continuous positive airway pressure (CPAP) ventilation via a tight fitting face mask was assessed in eight HIV-1 antibody-positive patients with Pneumocystis carinii pneumonia who were in hypoxaemic respiratory failure. All patients were conscious, able to protect their airway and not hypercapnic. Treatment was effective in seven patients. Prior to CPAP, mean (range) arterial oxygen tension was 6.7 (4.7-10.5) kPa in seven patients breathing oxygen via a face mask (FiO2 = 0.6), 6.1 kPa in one patient breathing room air and rose to 9.9 (6.8-12.8) kPa with CPAP (FiO2 = 0.6 and PEEP = 1.3 kPa in six patients and 2.6 kPa in one patient); the mean increase in PaO2 was 3.1 kPa (P less than 0.02). These seven patients experienced a rapid reduction in dyspnoea and their respiratory rate fell from a mean of 40 breaths min-1 to 32 breaths min-1 (P less than 0.001). One patient deteriorated rapidly on CPAP and died: no other complications were seen with this technique. CPAP was continued for a mean of 4.5 days and the seven responders all survived the episode of P. carinii pneumonia. We conclude that mask CPAP provides an effective means of improving oxygenation in severely hypoxaemic patients with P. carinii pneumonia.

A retrospective review was conducted of 22 human immunodeficiency virus type 1 (HIV-1)-infected children under 13 years of age presenting to an inner city pediatric emergency department to determine their clinical manifestations of disease and utilization of emergency department services. When compared with a population of 78 normal children, the infected children were more likely to present with cough, difficulty in breathing, and lethargy. Pneumonia, diarrhea, and dehydration were more common diagnoses in the infected children, who were more likely to be admitted, had more invasive procedures, and required more professional staff to provide care. There was no significant difference in the frequency of visits (visits/month of age) when comparing the two groups. As expected, the infected children presented with problems associated with pediatric HIV-1 infection. Our results suggest that HIV-1-infected children require an increased level of care in the emergency department and subsequent admission to the hospital. These children did not visit the emergency department more frequently than the controls. This may be the result of an active outpatient HIV clinic in our hospital, which is available to both scheduled and unscheduled patients.

This study examines the impact of HIV-1 infection and AIDS on 500 of 563 consecutive deaths at University Hospital, Kinshasa, Zaire, in late 1987. HIV-1 seroprevalence was 31% for the entire population and 43% for the 247 adults. Forty-two (38%) of the 110 HIV-1-seropositive adult deaths occurred in those between the ages of 25 and 34 years. The mean age of death for seropositives was 36 years, 7.5 years less than seronegative deaths. AIDS and AIDS-associated diagnoses such as cryptococcal meningitis, chronic diarrhea and pneumonia accounted for 42% of all adult deaths and 74% of all HIV-1-seropositive adult deaths. Seventeen per cent of 50 sera initially negative by enzyme-linked immunosorbent assay (ELISA) were ultimately found to be HIV-1-seropositive by Western blot or p24 antigen testing. The data indicate that HIV-1 infection and AIDS contribute significantly to adult mortality in Kinshasa population and that sensitivity of ELISA tests decreases in terminal HIV-1 infection.

A 56-year-old man was admitted with hemiparesis and shortness of breath. He was positive to human immunodeficiency virus (HIV) antibody and was diagnosed as acquired immunodeficiency syndrome (AIDS) with Kaposi's sarcoma and pneumocystis carinii pneumonia. He developed chronic photosensitivity and vitiligo preceding the onset of the AIDS-related complex (ARC). Association of the two skin lesions with HIV infection is very rare. Although the role of HIV infection in these skin lesions is not significant, the immunological responses in the early course of HIV infection may have contributed to the development of both of these skin lesions.

A 21 year old homosexual man presented with an acute pneumonitis during symptomatic seroconversion for human immunodeficiency virus (HIV-I) infection. The symptoms resolved spontaneously without any therapeutic interventions needed. Acute pneumonitis should be added to the ever-increasing spectrum of clinical manifestations in primary HIV-I infection.

Zidovudine (azidothymidine, Retrovir) and ddI (di-deoxy-inosine, Videx) interfere with the multiplication of HIV by incorporation into nascent DNA chains and interruption of the further linking of nucleotides. Zidovudine lowers early mortality in patients with Aids and pneumocystis carinii pneumonia. However, much of the effectiveness of zidovudine is lost later on; the average prolongation of life in treated patients is estimated to be about 1 year. About two thirds of patients with Aids can be treated with zidovudine; in the others, the drug is ineffective or contraindicated. Frequent blood counts are necessary to monitor myelotoxicity, even at relatively low doses of 500 mg/day. In contrast, zidovudine is well tolerated by asymptomatic patients with 200 to 500 CD4 lymphocytes/mm3, in whom it diminishes the incidence of Aids from about 7 to 3% during the first year of treatment, with less than 2% severe anemia or leukopenia. For patients who do not tolerate zidovudine, ddI is an alternative. It is not myelotoxic but can cause neuritis and pancreatitis, especially at doses in excess of 10 mg/kg/day. Although its antiviral effect is excellent both in vitro and in vivo, there is still a lack of firm data on its clinical value, such as the decrease in opportunistic infections and increase in survival.

Earlier diagnosis and improved therapies for the opportunistic infections have led to improved quality of life as well as survival time of patients with advanced HIV-related immunodeficiency. Most of the therapies can be administered on an outpatient basis. Outpatient treatment further contributes to improving the quality of life of the patients. Presentation, clinical aspects, treatment and prophylaxis of the five most frequent opportunistic infections in HIV-infected patients with advanced immunodeficiency in our outpatient clinic (oral and esophageal candidiasis, pneumocystis carinii pneumonia, herpes zoster, herpes simplex virus infection and cerebral toxoplasmosis) are discussed with respect to the practical implications.

We report a case of an HIV-infected adult with Chlamydia pneumoniae. Our patient presented with a clinical picture suggestive of Pneumocystis carinii pneumonia (PCP), but did not respond to empiric anti-PCP therapy. The diagnosis was eventually confirmed by bronchoscopy and serology. C. pneumoniae pneumonia should be considered in the differential of pathogens that cause interstitial infiltrates in HIV-infected persons.
