Opportunistic infections shortly after beginning highly active antiretroviral therapy.

The clinical benefit of highly active antiretroviral therapy (HAART) has been attributed to its suppression of viral replication and improvement in the CD4 lymphocyte count. However, the development of clinical symptoms secondary to previously silent opportunistic pathogens shortly after beginning HAART has been reported as a distinct clinical syndrome and seems to be associated with inflammatory phenomena surrounding a rapid restoration of the immune system in previously immunosuppressed patients. Herein, we report nine (3.6%) episodes of opportunistic infections (OI) in 247 human immunodeficiency virus (HIV)-infected patients undergoing HAART in a reference HIV/AIDS institution located in Madrid, Spain. In all instances, OI clustered within the first 3 months after beginning HAART. Episodes of cerebral toxoplasmosis (three cases), Pneumocystis carinii pneumonia (two cases), and herpes zoster (two cases) occurred in persons without a previous AIDS-defining illness, in addition a relapse of cytomegalovirus retinitis and a rebound in Kaposi's sarcoma were seen, respectively, in another two patients. Four of the nine subjects had a CD4 count above 200 cells/mm3 before HAART began. Of these, one developed Pneumocystis pneumonia and one other cerebral toxoplasmosis. In conclusion, prophylaxis and close clinical monitoring of HIV-infected patients should be considered for the first 3 months after beginning HAART, even for subjects without severe immunosuppression.

Initial assessment of patients infected with human immunodeficiency virus: the yield and cost of laboratory testing.

Our objective was to determine the yield and cost of standardized laboratory testing of HIV-infected patients entering medical care after testing positive for HIV. An HIV staging and referral clinic in a municipal public hospital was our site for a cross-sectional study, and 308 patients were evaluated in the clinic between February 1, 1990 and October 1, 1991. Patients underwent standardized laboratory testing, including hematologic studies, serum chemistries, infectious disease serologies, and chest radiographs. The percentage of abnormal results for each test was determined. Abnormal results were stratified as mild or severe. They were also examined with regard to whether injection drug users or other patient subgroups had higher percentages of abnormalities. Changes and Medicare reimbursements for the tests were also determined. There were substantial numbers of abnormalities in all types of laboratory testing. Only 3% of patients had normal CD4 lymphocyte counts; 85% had counts of < 500/mm3, and 35% were < 200/mm3. Forty-four percent of patients had at least one abnormal hematologic study; 8% were severe. Nearly 75% had abnormal liver function tests; 20% of these were severe abnormalities. Fifteen percent of patients were PPD-positive, and > 50% were anergic. Fourteen percent had a positive nonspecific test for syphilis, and 7% had a positive confirmatory test. Fourteen percent of patients had an abnormal chest radiograph.(ABSTRACT TRUNCATED AT 250 WORDS)

Evaluation of effectiveness of the 23-valent pneumococcal capsular polysaccharide vaccine for HIV-infected patients.

BACKGROUND: We conducted a retrospective case-control study to evaluate effectiveness of pneumococcal vaccine against invasive disease among adults with human immunodeficiency virus (HIV) infection in San Francisco, Calif, and Atlanta, Ga. METHODS: Case patients were 18- to 55-year-old subjects with HIV infection who were admitted to selected hospitals in Atlanta or San Francisco from February 1992 to April 1995 from whom Streptococcus pneumoniae was isolated from a normally sterile site. Controls were HIV-infected patients of similar age matched to cases by hospital of admission and CD4 lymphocyte count (<0.20, 0.20-0.499, >/=0.50 x 10(9)/L [<200, 200-499, >/=500 cells/mm(3)]) or clinical stage of acquired immunodeficiency syndrome. Case and control subjects were restricted to persons known to have HIV infection before hospital admission. Analysis used matched univariate and conditional logistic regression. RESULTS: One hundred seventy-six case patients and 327 controls were enrolled. By univariate analysis, persons with pneumococcal disease were more likely to be black, be current smokers, and have close contact with children. Adjusted for these factors and CD4 cell count, pneumococcal vaccine effectiveness was 49% (95% confidence interval [CI], 12%-70%). Adjusting for all variables and key interaction terms, vaccine effectiveness among whites was 76% (95% CI, 35%-91%), whereas effectiveness among blacks was 24% (95% CI, -50% to 61%). Among controls, vaccination was significantly less common among blacks (29% vs 45%; P<.005). CONCLUSIONS: Pneumococcal vaccine demonstrated protection against invasive pneumococcal infections among white but not black HIV-infected adults. Failure to demonstrate effectiveness among blacks may be due to limited power because of low use of the vaccine in this population, immunization at more advanced stages of immunosuppression, or unmeasured factors. These data support current recommendations for use of pneumococcal vaccine in HIV-infected persons and highlight a clear need for strategies to improve vaccine-induced protection.

Progressive multifocal leukoencephalopathy in a patient with acquired immunodeficiency syndrome (AIDS) manifesting Gerstmann's syndrome.

We reported a case of acquired immunodeficiency syndrome (AIDS) via multiple blood transfusions, who manifested progressive multifocal leukoencephalopathy (PML) about 18 months after the development of AIDS. PML initiated with right hemiparesis, dysphasia, and Gerstmann's syndrome and resulted in death within 2 months after the onset. Neuroimaging examinations revealed white matter lesions mainly in the left posterior parietal lobe. The cortical gray matter also showed abnormal signal intensity. Peripheral CD4+ lymphocyte count was 81/microl. Routine cerebrospinal fluid (CSF) examinations were negative. CSF antibodies against herpes simplex virus, varicella-zoster virus, cytomegalovirus, Epstein-Barr virus as well as serum antibody against toxoplasma gondii were negative. Though autopsy or biopsy of the brain was not performed, JC virus genomes were detected in the CSF sample by a polymerase chain reaction, and their sequencing showed unique alterations of the regulatory regions, characteristic to PML-type JC virus.

Repeat-cycle study of high-dose intravenous 4162W94 anti-CD4 humanized monoclonal antibody in rheumatoid arthritis. A randomized placebo-controlled trial.

OBJECTIVE: Results of an earlier open-label pilot study showed that 4162W94 was a relatively non-depleting anti-CD4 monoclonal antibody that induced >80% down-modulation of CD4 molecules from the surface of T lymphocytes. This placebo-controlled repeat-cycle study was conducted in active rheumatoid arthritis (RA) patients to determine the duration of CD4 blockade required to achieve lasting clinical benefit. METHODS: Following DMARD washout, 48 patients (i.e. three cohorts of 16 patients) with ACR-defined RA were to be dosed with 1 (cohort 1), 2 (cohort 2) or 3 (cohort 3) cycles of 5x300 mg 4162W94 or placebo (12 and 4 patients per cohort respectively) at monthly intervals. There was at least 3 months of follow-up after dosing. Clinical outcome was assessed in evaluable patients (receiving at least 80% of each dose course) using ACR20 criteria (required on two consecutive visits). CD4 lymphocyte counts and adverse events were also monitored. RESULTS: Sixteen patients were dosed in each of the first two cohorts; however, the dose was reduced in cohort 3 after five patients had received up to two dose cycles due to accumulating evidence of a high frequency of skin rash. These patients were analysed according to the number of cycles received. A further eight patients received 5x100 mg for one to three cycles prior to stopping the study for administrative reasons. Four of 13 (P=0.119 vs placebo) and 7/13 (P=0.015 vs placebo) in cohorts 1 and 2 respectively achieved ACR20 response on at least two consecutive occasions. No patient receiving 5x100 mg/day or placebo achieved ACR20. Four patients were still responding at the end of the 3-month follow-up period. CD4 lymphocyte suppression (<0.2x10(9)/l on at least two successive occasions) occurred in 11/34 patients who received 4162W94 vs none on placebo. Rash occurred in 21/34 monoclonal antibody-treated patients, including one case of biopsy-confirmed cutaneous vasculitis and 1/11 placebo patients. CONCLUSION: 4162W94 demonstrated significant clinical efficacy in this study. However, because of unacceptable CD4 lymphopenia and rash, the original hypothesis that prolonged CD4 blockade would give lasting clinical benefit was not tested.

Emergence of drug resistance mutations in a group of HIV-infected children taking nelfinavir-containing regimens.

HIV-1-infected children are often treated with therapy regimens including protease inhibitors (PIs). We monitored the virologic response in a small group of pediatric patients undergoing therapy with regimens including the PI nelfinavir and determined whether new drug resistance mutations were present immediately after virologic failure. Seventeen reverse transcriptase inhibitor (RTI)-experienced children starting nelfinavir-containing therapy regimens were studied. After virologic failure, HIV-1 protease (PR) and RT sequences were examined for drug resistance mutations. Viral load levels decreased to <400 HIV RNA copies/ml in six patients and remained at <400 HIV RNA copies/ml in four patients. Three patients did not respond virologically; all three had mutations specific for one or more of their regimen drugs either before or soon after nelfinavir initiation. The virologic response was transient in eight patients whose viral loads did not decrease to <400 HIV RNA copies/ml. Genotypic data from seven of the eight patients revealed mutations specific for one or more of their regimen drugs after virologic rebound. PI resistance mutations occurred in eight patients: D30N in six, and L90M in three. In three patients, the only new mutation after failure was the RT mutation M184V. Despite virologic failure, sustained increases in CD4+ lymphocyte counts were noted in eight patients. We conclude that in this small group of pediatric patients, virologic failure occurred in all patients whose viral loads did not become undetectable after the switch to a nelfinavir-containing regimen. After failure, new drug resistance mutations were found in either PR or RT. Studies of larger cohorts are warranted to determine whether HIV-1 genotypic data can help in the formulation of effective salvage therapies in children.

A systematic review of the clinical significance of pulmonary Mycobacterium kansasii isolates in HIV infection.

Guidelines recommend treating HIV-infected patients with pulmonary Mycobacterium kansasii infection only in the presence of multiple positive cultures and clinical and radiographic abnormalities. Some authors suggest a single positive culture warrants treatment. A systematic literature review was done to determine whether HIV-infected patients who had M. kansasii isolated from respiratory specimens may have an indolent infection (often referred to as colonization) not requiring treatment and to determine the utility of diagnostic criteria in distinguishing disease from indolent infection. Sixteen studies were included, with at least 573 patients: mean age 44 years; 91% male; 64% men who had sex with men; 35% injection drug users; and median CD4 lymphocyte count of 2-381 cells/microL. The median rate of indolent infection was 8%. Of the few patients who did not satisfy diagnostic criteria and were left untreated, outcomes were generally favorable. Overall, survival was longer in treated patients (mean 12 vs. 4 months). Indolent pulmonary infection with M. kansasii may exist in the setting of HIV, but published data do not provide adequate information to identify such patients. It is unclear whether unfulfilled diagnostic criteria necessarily imply the absence of disease in this context.

A safety study of oral valganciclovir maintenance treatment of cytomegalovirus retinitis.

Valganciclovir, an oral prodrug of the anti-cytomegalovirus (CMV) agent ganciclovir, was evaluated in a single-arm open-label safety study. AIDS patients (median CD4 lymphocyte count of 140 cells/microL) with treated CMV retinitis (N = 212) received 900-mg once-daily valganciclovir maintenance therapy with courses of 900-mg twice-daily valganciclovir induction therapy as needed to treat progression. After a median treatment duration of 372 days, the adverse event profile was similar to that reported for intravenous (IV) and oral ganciclovir. Adverse event rates of note were diarrhea (35%), nausea (23%), fever (18%), neutropenia (absolute neutrophil count <500 cells/microL) (10%), and anemia (hemoglobin <8.0 g/dL) (12%). Consistent with prior treatment studies of oral ganciclovir, IV catheter-related adverse events were uncommon (6%) and lower than previously reported for IV ganciclovir. The mortality rate was 0.072 deaths per patient-year. Progression of CMV retinitis occurred in 17% of patients during the study treatment period, usually in association with a low CD4 cell count. Other than a higher than expected frequency of oral candidiasis (17%), no clinical toxicities or laboratory abnormalities occurred during treatment with valganciclovir that have not been observed during treatment with ganciclovir.

Delayed tooth eruption: association with severity of HIV infection.

PURPOSE: HIV status is monitored by expression of clinical symptoms as well as CD4 lymphocyte counts. The purpose of this study is to assess the relationship between delayed dental eruption (DDE) and the progression of pediatric HIV infection to AIDS. METHODS: A population of 70 perinatally HIV-infected children, aged 5 months to 13 years at their time of entry into the study, received dental examinations. Regression analysis between dental age and chronological age was performed. Subject CDC classification, adjusted for age, was used to determine an association between eruptive delay and severity of disease progression. RESULTS: Data revealed no significant difference in timing of eruption based on severity of CD4 depletion alone (P = 0.09). However, clinical symptom status was strongly associated with DDE (P = 0.003). The relationship between symptoms and DDE persisted after controlling for CD4 depletion. CONCLUSIONS: Our study indicates that there is a correlation between the progression from HIV infection to Pediatric AIDS and DDE and that this delay is most closely linked to severity of symptoms and not CD4 depletion.

[Cytomegalovirus retinitis].

Cytomegalovirus (CMV) retinitis is the most common intraocular infection in patients with Acquired immunodeficiency syndrome (AIDS). Approximately 25% of patients with AIDS will develop CMV retinitis during their life time. It is generally associated with CD4+ lymphocyte counts of less than 50 cells/microliter. Clinically, the most characteristic feature of CMV retinitis is a yellow-white lesion of retinal necrosis with a granular border extending into the surrounding retina. At present, ganciclovir and foscarnet have been approved for the treatment of CMV retinitis in patients with AIDS. Although both drugs arrest the progression of retinitis, relapse often occurs. More than ever, ophthalmologists have a special obligation to alleviate both the physical and psychological suffering of patients with CMV retinitis.

Ethnic differences in stage of presentation of adults newly diagnosed with HIV-1 infection in south London.

OBJECTIVES: To establish whether there were ethnic differences in demographic characteristics, the stage at HIV diagnosis and reasons for and location of HIV testing between 1998 and 2000 in a large ethnically diverse HIV-1-infected clinic population in south London in the era of highly active antiretroviral therapy. METHODS: A retrospective review was carried out of all persons >18 years old attending King's College Hospital with a first positive HIV-1 test between 1 January 1998 and 31 October 2000, and of a random sample of patients attending St Thomas' hospital with a first positive HIV-1 test in the same period. Demographic data, details of reasons for and site of HIV test, clinical stage, CD4 lymphocyte count and HIV-1 viral load at HIV diagnosis were abstracted from the local database and medical records. Comparisons were made according to ethnic group (white, black African and black Caribbean) and over time (1998, 1999 and 2000). RESULTS: Of the 494 patients with new HIV-1 diagnoses between January 1998 and December 2000, 179 (36.2%) were white, 270 (54.7%) were black African and 45 (9.1%) were black Caribbean. There were significant differences across the ethnic groups in HIV risk group, reasons for and site of HIV testing, and clinical and CD4 stage at diagnosis. Among whites, 72.6% were men who had sex with men, 3.4% injecting drug users and 21.2% heterosexuals, compared to 2.2%, 0.4% and 93.3% among black Africans, and 28.9%, 0% and 68.9% among black Caribbeans (P<0.001). Black Africans were more likely to present with an AIDS diagnosis (21.3%) and a lower CD4 cell count [223 cells/microL; interquartile range (IQR) 88-348] compared to both whites (9.9%; 358 cells/microL; IQR 151-508) and black Caribbeans (17.9%; 294 cells/microL; IQR 113-380), who were intermediate between whites and black Africans in their stage of presentation. There was a statistically nonsignificant trend with time, between 1998 and 2000, towards earlier diagnosis based on the CD4 cell count in whites (323 and 403 cells/microL) and black Caribbeans (232 and 333 cells/microL), but a later diagnosis in black Africans (233 and 175 cells/microL). The majority of black Africans were HIV-tested as a result of suggestive symptoms or antenatal screening (58.4%) rather than because of perceived risk (40.5%), in contrast to the situation in whites (24.1% vs. 71.7%, respectively) or black Caribbeans (34.5% vs. 65.5%, respectively) (P<0.001). We found no significant differences across ethnic groups in age, HIV-1 viral load or year of HIV diagnosis. CONCLUSIONS: Black Africans continue to present with more advanced HIV disease than whites or black Caribbeans, with no evidence of any trend towards earlier diagnosis. Future educational campaigns designed to promote the uptake of HIV testing among black Africans and black Caribbeans will need to address the multiple barriers to testing, including misperception of risk, stigma and ready access to testing.

Lymphocyte subpopulations in intrauterine growth retardation in women with or without previous pregnancies.

OBJECTIVE: To evaluate lymphocyte subpopulations in pregnant women with intrauterine growth retardation (IUGR). STUDY DESIGN: Forty-two normotensive and healthy women with singleton pregnancies and intrauterine growth retardation were studied in the third trimester of pregnancy and compared with 42 normal pregnant women. Peripheral blood lymphocytes were studied using murine monoclonal antibodies and flow cytometry. RESULTS: B-lymphocytes in both total number (312.54 vs. 163.19 cells/mm3; P = 0.000003) and percentage (11.04% vs. 7.07%; P = 0.000002) were significantly increased in patients with IUGR in comparison to normal pregnant women. Significant correlations were found between birthweight and both total number and percentage of lymphocytes B. In primigravid women, we found that women with IUGR had a higher total lymphocyte count (2749.09 vs. 2130 cells/mm3; P = 0.006), higher T-lymphocyte count (2053.77 vs. 1676.40 cells/mm3; P = 0.02), higher B-lymphocyte count and percentage (309.13 vs. 145.36 cells/mm3; P = 0.000001) (11.45 vs. 6.81%); P = 0.00001), higher CD4 lymphocyte count and percentage (1342.68 vs. 972.22 cells/mm3, P = 0.001) (49.18 vs. 44.04%; P = 0.04), lower CD8-lymphocytes percentage (28.27 vs. 32.9%; P = 0.04), and higher CD4/CD ratio (1.83 vs. 1.46; P = 0.02) than the normal control group. CONCLUSIONS: B-lymphocytes are increased in women with IUGR in comparison to women with normal pregnancies and there was a significant negative correlation between maternal B-lymphocytes and birthweight. With respect to T-lymphocytes, the immunological profile is different according to the presence or absence of a previous pregnancy. Fetal immunological rejection could be involved in the pathogenesis of IUGR in primigravid women, but in multigravid women there were no differences between women with IUGR and those with normal fetal growth.

Risk factors for transmission of Mycobacterium tuberculosis from HIV-infected tuberculosis patients, Botswana.

OBJECTIVE: To identify risk factors for transmission of Mycobacterium tuberculosis from patients with tuberculosis and human immunodeficiency virus (HIV) infection in Botswana. DESIGN: Transmission was studied in 210 children aged <10 years (contacts) of unknown HIV status exposed to 51 adults with tuberculosis (index cases), including 41/49 (83.7%) with HIV infection. METHODS: Data collected on index cases included demographics, clinical and social characteristics, sputum, HIV, and CD4 lymphocyte results. Tuberculin skin testing was performed on contacts, and their parent or guardian was interviewed. A positive test was defined as > or = 10 mm induration. Skin test results were compared with results obtained from a population survey of children of similar age from the same community. RESULTS: A positive skin test was found in 12.1% of exposed children compared with 6.2% in the community (P = 0.005). Of the infected children, 22 (78.6%) were contacts of a close female relative. The risk of transmission increased with the degree of sputum smear positivity for acid-fast bacilli among female index cases (10.8% if smear 0+, 9.3% if smear 1+,29.4% if smear 2+, 44% if smear 3+, P < 0.001). In multivariate analysis, severe immunodeficiency (CD4 lymphocyte count <200 cells/mm3) among HIV-infected index cases was protective against transmission (OR 0.08, 95%CI 0.01-0.5, P = 0.006). CONCLUSION: The intensity of exposure to tuberculosis patients and the degree of sputum smear positivity for acid-fast bacilli remain important risk factors for transmission of M. tuberculosis during the era of HIV. However, tuberculosis patients with advanced AIDS may be less infectious than patients in earlier stages of AIDS.

Ocular flora of patients with AIDS compared with those of HIV-negative patients.

PURPOSE: To determine whether there are quantitative or qualitative differences in the ocular flora of patients with acquired immunodeficiency syndrome (AIDS) compared with human immunodeficiency virus (HIV)-negative patients. METHODS: Forty patients with AIDS and 42 HIV-negative controls were sex and age matched. All subjects had a detailed anterior segment examination, including Schirmer's test, rose bengal staining, and quantitative cultures of the conjunctiva and lids. Statistical evaluation of the relation between AIDS, keratoconjunctivitis sicca (KCS), and ocular flora was performed. RESULTS: No differences were observed in the types or numbers of organisms isolated from the conjunctiva or lids of patients with AIDS and HIV-negative subjects. Ocular flora was not influenced by use of systemic antibiotics, level of immunosuppression as measured by CD4 lymphocyte counts, KCS, or other ocular-surface disease. One AIDS patient was colonized by large numbers of Haemophilus influenzae OU with minimal clinical signs of inflammation or infection. CONCLUSION: There do not appear to be any differences in the ocular flora of HIV-negative patients and patients with AIDS. Presence of KCS and level of immunosuppression do not appear to affect the ocular flora in patients with AIDS.

Body composition in HIV-infected women.

Although loss of lean body mass is a common complication of human immunodeficiency virus (HIV) infection that can occur across the disease trajectory, few studies have characterized the body composition of HIV-infected women. We used bioelectrical impedance analysis to characterize the body composition of HIV-infected (n = 56) and uninfected (n = 12) women who were matched on percentage of ideal body weight. The HIV-infected women did not differ from the uninfected women by height-adjusted fat mass or body cell mass. Intergroup comparisons among the HIV-infected women showed that underweight women had significantly less fat mass than did normal-weight women but did not significantly differ with respect to body cell mass. Among all HIV-infected women, CD4(+) lymphocyte count was positively correlated with fat mass (r = 0.32, P = 0.01) but not with body cell mass. No significant correlations were found between any body-composition parameter and plasma viral load. Our findings suggest that, unlike men, HIV-infected underweight women show a preferential loss of fat mass and a relative preservation of body cell mass. This altered pattern of weight loss may relate to higher premorbid fat stores in women and/or hormonal differences.

Correlation between CD4+ counts and prevalence of cytomegalovirus retinitis and human immunodeficiency virus-related noninfectious retinal vasculopathy in patients with acquired immunodeficiency syndrome.

We prospectively studied 132 patients with acquired immunodeficiency syndrome (AIDS) to determine the cross-sectional prevalence of cytomegalovirus retinitis. All patients had serum CD4+ lymphocyte counts to determine the degree of immune dysfunction. Correlations between CD4+ counts, the presence of cytomegalovirus retinitis or human immunodeficiency virus (HIV)-related noninfectious retinal vasculopathy, and ocular symptoms were made. The study disclosed that 26 of 132 patients with AIDS (20%) had cytomegalovirus retinitis. However, subset analysis according to CD4+ count disclosed that in patients with CD4+ counts of 50 cells/mm3 or less, 26 of 87 (30%) had cytomegalovirus retinitis, whereas in patients with CD4+ counts of 50 cells/mm3 or more, none of 45 was noted to have cytomegalovirus retinitis. Similarly, 46 of 132 patients (35%) were noted to have HIV-related noninfectious retinal vasculopathy, with a trend toward increasing prevalence associated with declining CD4+ count. In patients with CD4+ counts of 50 cells/mm3 or less, 39 of 87 (45%) had HIV-related noninfectious retinal vasculopathy, whereas seven of 45 patients (16%) with CD4+ counts of 50 cells/mm3 or more were noted to have these changes. We confirmed the clinical impression that cytomegalovirus retinitis and HIV-related noninfectious retinal vasculopathy are late manifestations of AIDS, demonstrated an increased risk for patients with low CD4+ counts, and suggested a basis for coherent chemoprophylaxis and screening strategies for cytomegalovirus retinitis.

A behavioral-medicine program in HIV. Implications for quality of life.

The purpose of this descriptive study is to examine quality of life issues in participants in a behavioral-medicine group (N = 24). Of the sample, 60% indicated current use of complementary therapies. Sexual functioning, a subscale of the quality-of-life measure, was positively correlated with length of time with HIV. CD4+ lymphocyte counts were not significantly correlated with quality of life (QOL). Viral load (VL) was positively correlated with the social-support subscale of the QOL scale. Use of body therapies (massage, acupuncture) was associated with social functioning and use of nutritional therapies was associated with mental health. Results of the study indicate that clinical interventions, including behavioral-medicine interventions and complementary therapies for persons with HIV/AIDS, can result in greater QOL.

Emerging patterns of HIV transmission: the value of alternative surveillance methods.

OBJECTIVE: To assess the current patterns of HIV transmission in Los Angeles County and determine if AIDS surveillance data accurately reflect these patterns. DESIGN: Records-based cohort study. METHODS: The demographic and HIV risk characteristics of persons considered to be recently infected with HIV (CD4+ count > 700 x 10(6)/l) were determined and compared with the characteristics of persons meeting the Centers for Disease Control and Prevention (CDC) 1993 AIDS case definition. Data were obtained for patients with HIV infection enrolled from four HIV outpatient clinics and analyzed between August 1991 and July 1993. RESULTS: The patient cohort included 1857 persons with HIV infection; 1096 (59.1%) met the CDC 1993 AIDS case definition and 134 (7.2%) had a CD4+ lymphocyte count > 700 x 10(6)/l. The median CD4+ count for the group presumed to be recently infected was 809 x 10(6)/l. Persons considered recently infected with HIV were more likely than those meeting the AIDS case definition to be female (26.1 and 14.5%, respectively; P < 0.001), black (28.4 and 18.2%, respectively; P = 0.001), or male homosexual injecting drug users (IDU; 6.7 and 3.4%, respectively; P = 0.05). After controlling for confounding variables by logistic regression, persons recently infected were more likely to be female [adjusted odds ratio (OR), 3.4; 95% confidence interval (CI), 1.8-6.5; P < 0.001], black (adjusted OR, 1.6; 95% CI, 1.1-2.5; P = 0.02) or male homosexual IDU (adjusted OR, 2.4; 95% CI, 1.1-5.2; P = 0.02) than persons with AIDS. CONCLUSIONS: Our results suggest that the HIV epidemic in Los Angeles County is currently advancing into different subpopulations and indicate that the current patterns of HIV transmission in the County are not fully reflected in standard AIDS surveillance activities. However, our data must be interpreted cautiously because of potential selection and misclassification biases. These findings illustrate the benefits of alternative surveillance mechanisms in detecting important changes in HIV transmission and defining groups at risk, especially in jurisdictions without HIV reporting.
