Abstract
OBJECTIVE To explore the comparative effectiveness of pharmacological interventions for hand osteoarthritis (OA). METHODS We systematically searched Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials from inception until 26 December 2021, for randomised trials of pharmacological interventions for people with hand OA. Two reviewers independently extracted study data and assessed the risk of bias. We calculated the effect sizes for pain (standardised mean differences) using Bayesian random effects models for network meta-analysis (NMA) and pairwise meta-analysis. Based on a pre-specified protocol, we prospectively registered the study at PROSPERO, CRD42021215393. RESULTS We included 72 trials with 7609 participants. 65 trials (n=5957) were eligible for the quantitative synthesis, investigating 29 pharmacological interventions. Oral non-steroidal anti-inflammatory drugs (NSAIDs) and oral glucocorticoids' NMA effect sizes were -0.18 (95% credible interval -0.36 to 0.02) and -0.54 (-0.83 to -0.24), respectively, compared with placebo, and the result was consistent when limiting evidence to the pairwise meta-analysis of trials without high risk of bias. Intra-articular hyaluronate, intra-articular glucocorticoids, hydroxychloroquine, and topical NSAIDs' NMA effect sizes were 0.22 (-0.08 to 0.51), 0.25 (0.00 to 0.51), -0.01 (-0.19 to 0.18), and -0.14 (-0.33 to 0.08), respectively, compared with placebo. Oral NSAIDs were inferior to oral glucocorticoids with an NMA effect size of 0.36 (0.01 to 0.72). No intervention was superior to placebo when stratifying for thumb and finger OA. CONCLUSION Oral NSAIDs and glucocorticoids are apparently effective pharmacological interventions in hand OA. Intra-articular therapies and topical NSAIDs were not superior to placebo.

Abstract
We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log10 increase (i.e., a ~3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited CD4 cell decline twice as fast as, 6604 individuals with other subtype-B strains. Without treatment, advanced HIV-CD4 cell counts below 350 cells per cubic millimeter, with long-term clinical consequences-is expected to be reached, on average, 9 months after diagnosis for individuals in their thirties with this variant. Age, sex, suspected mode of transmission, and place of birth for the aforementioned 109 individuals were typical for HIV-positive people in the Netherlands, which suggests that the increased virulence is attributable to the viral strain. Genetic sequence analysis suggests that this variant arose in the 1990s from de novo mutation, not recombination, with increased transmissibility and an unfamiliar molecular mechanism of virulence.

Abstract
INTRODUCTION OMERACT uses an evidence-based framework known as the 'OMERACT Filter Instrument Selection Algorithm' (OFISA) to guide decisions in the assessment of outcome measurement instruments for inclusion in a core outcome set for interventional and observational clinical trials. METHODS A group of OMERACT imaging and patient-centered outcome methodologists worked with imaging outcome groups to facilitate the selection of imaging outcome measurement instruments using the OFISA approach. The lessons learned from this work influenced the evolution to Filter 2.2 and necessitated changes to OMERACT's documentation and processes. RESULTS OMERACT has revised documentation and processes to incorporate the evolution of instrument selection to Filter 2.2. These revisions include creation of a template for detailed definitions of the target domain which is a necessary first step for instrument selection, modifications to the Summary of Measurement Properties (SOMP) table to account for sources of variability, and development of standardized reporting tables for each measurement property. CONCLUSIONS OMERACT Filter 2.2 represents additional modifications of the OMERACT guide for working groups in their rigorous assessment of measurement properties of instruments of various types, including imaging outcome measurement instruments. Enhanced reporting aims to increase the transparency of the evidence base leading to judgements for the endorsement of instruments in core outcome sets.

Abstract
OBJECTIVES Further knowledge about typical hand osteoarthritis (OA) characteristics is needed for the development of new classification criteria for hand OA. METHODS In a cross-sectional multi-centre international study, a convenience sample of patients from primary and secondary/tertiary care with a physician-based hand OA diagnosis (n = 128) were compared with controls with hand complaints due to inflammatory or non-inflammatory conditions (n = 70). We examined whether self-reported, clinical, radiographic and laboratory findings were associated with hand OA using logistic regression analyses. Discrimination between groups was assessed by calculating the area under receiver operating curves (AUC). RESULTS Strong associations with hand OA were observed for radiographic osteophytes (OR = 1.62, 95% CI 1.40 to 1.88) and joint space narrowing (JSN) (OR = 1.57, 95% CI 1.36 to 1.82) in the distal interphalangeal (DIP) joints with excellent discrimination (AUC = 0.82 for both). For osteophytes and JSN, we found acceptable discrimination between groups in the proximal interphalangeal joints (AUC = 0.77 and 0.78, respectively), but poorer discrimination in the first carpometacarpal joints (AUC = 0.67 and 0.63, respectively). Painful DIP joints were associated with hand OA, but were less able to discriminate between groups (AUC = 0.67). Age and family history of OA were positively associated with hand OA, whereas negative associations were found for pain, stiffness and soft tissue swelling in metacarpophalangeal joints, pain and marginal erosions in wrists, longer morning stiffness, inflammatory biomarkers and autoantibodies. CONCLUSIONS Differences in symptoms, clinical findings, radiographic changes and laboratory tests were found in patients with hand OA versus controls. Radiographic OA features, especially in DIP joints, were best suited to discriminate between groups.

Abstract
Background The Netherlands has provided unrestricted access to direct-acting antivirals (DAAs) since November 2015. We analyzed the nationwide hepatitis C virus (HCV) treatment uptake among patients coinfected with human immunodeficiency virus (HIV) and HCV. Methods Data were obtained from the ATHENA HIV observational cohort in which >98% of HIV-infected patients ever registered since 1998 are included. Patients were included if they ever had 1 positive HCV RNA result, did not have spontaneous clearance, and were known to still be in care. Treatment uptake and outcome were assessed. When patients were treated more than once, data were included from only the most recent treatment episode. Data were updated until February 2017. In addition, each treatment center was queried in April 2017 for a data update on DAA treatment and achieved sustained virological response. Results Of 23574 HIV-infected patients ever linked to care, 1471 HCV-coinfected patients (69% men who have sex with men, 15% persons who [formerly] injected drugs, and 15% with another HIV transmission route) fulfilled the inclusion criteria. Of these, 87% (1284 of 1471) had ever initiated HCV treatment between 2000 and 2017, 76% (1124 of 1471) had their HCV infection cured; DAA treatment results were pending in 6% (92 of 1471). Among men who have sex with men, 83% (844 of 1022) had their HCV infection cured, and DAA treatment results were pending in 6% (66 of 1022). Overall, 187 patients had never initiated treatment, DAAs had failed in 14, and a pegylated interferon-alfa-based regimen had failed in 54. Conclusions Fifteen months after unrestricted DAA availability the majority of HIV/HCV-coinfected patients in the Netherlands have their HCV infection cured (76%) or are awaiting DAA treatment results (6%). This rapid treatment scale-up may contribute to future HCV elimination among these patients.

Since publication of the European League Against Rheumatism (EULAR) recommendations for management of hand osteoarthritis (OA) in 2007 new evidence has emerged. The aim was to update these recommendations. EULAR standardised operating procedures were followed. A systematic literature review was performed, collecting the evidence regarding all non-pharmacological, pharmacological and surgical treatment options for hand OA published to date. Based on the evidence and expert opinion from an international task force of 19 physicians, healthcare professionals and patients from 10 European countries formulated overarching principles and recommendations. Level of evidence, grade of recommendation and level of agreement were allocated to each statement. Five overarching principles and 10 recommendations were agreed on. The overarching principles cover treatment goals, information provision, individualisation of treatment, shared decision-making and the need to consider multidisciplinary and multimodal (non-pharmacological, pharmacological, surgical) treatment approaches. Recommendations 1-3 cover different non-pharmacological treatment options (education, assistive devices, exercises and orthoses). Recommendations 4-8 describe the role of different pharmacological treatments, including topical treatments (preferred over systemic treatments, topical non-steroidal anti-inflammatory drugs (NSAIDs) being first-line choice), oral analgesics (particularly NSAIDs to be considered for symptom relief for a limited duration), chondroitin sulfate (for symptom relief), intra-articular glucocorticoids (generally not recommended, consider for painful interphalangeal OA) and conventional/biological disease-modifying antirheumatic drugs (discouraged). Considerations for surgery are described in recommendation 9. The last recommendation relates to follow-up. The presented EULAR recommendations provide up-to-date guidance on the management of hand OA, based on expert opinion and research evidence.

Abstract
Due to the introduction of combination antiretroviral therapy (cART) 20 years ago, HIV infection in the Netherlands has changed from a fatal disease to a chronic condition with a near normalized life expectancy. The average age of HIV-positive patients continues to increase, as does the prevalence of non-HIV-related comorbidity. The number of new HIV diagnoses seems to be decreasing in the Netherlands, which is partly due to increased testing, earlier diagnosis, prompt cART initiation, and achievement of high levels of viral suppression, resulting in a reduced likelihood of onward transmission. In order to further curb the epidemic, it is important that as yet undiagnosed people living with HIV are identified as soon as possible. All practicing physicians in the Netherlands can contribute to this goal.

Abstract
BACKGROUND As a result of effective combination antiretroviral therapy (cART) and advanced supportive healthcare, a growing number of human immunodeficiency virus (HIV)-infected children survive into adulthood. The period of transition to adult care is often associated with impaired adherence to treatment and discontinuity of care. We aimed to evaluate virological and social outcomes of HIV-infected adolescents and young adults (AYAs) before and after transition, and explore which factors are associated with virological failure. METHODS We included 59 HIV-infected AYAs from the Netherlands who had entered into pediatric care and transitioned from pediatric to adult healthcare. We used HIV RNA load and cART data from the Dutch Stichting HIV Monitoring database (1996-2014), and collected social and treatment data from patients' medical records from all Dutch pediatric HIV treatment centers and 14 Dutch adult treatment centers involved. We evaluated risk factors for virological failure (VF) in a logistic regression model adjusted for repeated measurements. RESULTS HIV VF occurred frequently during the study period (14%-36%). During the transition period (from 18 to 19 years of age) there was a significant increase in VF compared with the reference group of children aged 12-13 years (odds ratio, 4.26 [95% confidence interval, 1.12-16.28]; P = .03). Characteristics significantly associated with VF were low educational attainment and lack of autonomy regarding medication adherence at transition. CONCLUSIONS HIV-infected AYAs are vulnerable to VF, especially during the transition period. Identification of HIV-infected adolescents at high risk for VF might help to improve treatment success in this group.

Abstract
Within the Dutch Acute HCV in HIV Study, a surveillance system was initiated to estimate the incidence of hepatitis C virus (HCV) infections in 2014. Following the Dutch HIV treatment guidelines, HIV-positive men having sex with men (MSM) in 19 participating centers were screened. Ninety-nine acute HCV infections were reported, which resulted in a mean incidence of 11 per 1000 patient-years of follow-up. Unfortunately, the HCV epidemic among Dutch HIV-positive MSM is not coming to a halt.

Abstract
OBJECTIVES High levels of soluble CD27 (sCD27), a marker of immune activation, are found in several infectious [including human immunodeficiency virus type-I (HIV-1)] and autoimmune diseases; however, a direct biological effect of sCD27 on B cells has not been established. The aim of this study was to investigate whether sCD27, by binding to CD70, can induce immunoglobulin G (IgG) production from B cells. METHODS B cells from healthy and HIV-1-infected individuals were cultured with recombinant human sCD27 (rhsCD27), and IgG production was measured. The role of rhsCD27 in inducing the expression of transcription factors involved in plasma cell differentiation was evaluated. Furthermore, we investigated the impact of different cytokines on the modulation of CD70 expression on B cells and the relationship between levels of IgG and sCD27 in serum from healthy and HIV-1-infected individuals. RESULTS We demonstrated that rhsCD27 induced IgG production from antigen-primed (CD27+) B cells. This effect was mediated by rhsCD27 binding to CD70 on B cells leading to activation of Blimp-1 and XBP-1, transcription factors associated with plasma cell differentiation. We found a significant correlation between levels of serum sCD27 and IgG in HIV-1-infected individuals and healthy controls. CONCLUSIONS sCD27 may act to enhance immunoglobulin production and differentiation of activated memory or recently antigen-experienced B cells, thus providing an activation signal to antigen-experienced B cells. This mechanism may operate during autoimmune and chronic infectious diseases, situations in which continuous immune activation leads to upregulation of CD70 expression and increased sCD27 cleavage.

Abstract
Vaccination has been shown to be one of the most powerful tools to decrease morbidity and mortality caused by an array of infectious diseases. The risk and complications of some vaccine-preventable diseases is higher in HIV-infected individuals, underscoring the importance of vaccination in these patients. However, the immune response upon vaccination is generally impaired and shorter lasting in HIV-infected individuals, especially in those with low CD4+ T-lymphocyte counts and detectable HIV RNA, as compared with healthy controls. Even in patients responding to antiretroviral treatment, an impaired immune response may persist despite normalization of the CD4+-cell count. Caution with live-attenuated vaccines is warranted in HIV-infected individuals with low CD4 T-lymphocyte counts. Decisions regarding administering a live-attenuated vaccine should be made after weighing the risks and benefits on an individual basis. In this article the immunology of vaccination in HIV-infected individuals, as well as the most relevant caveats of vaccination in this patient group, are reviewed in addition to the currently available information concerning the influenza A/H1N1 2009 monovalent vaccine.

Abstract
BACKGROUND Many strategies, including intradermal vaccination, have been tested to augment antibody responses upon vaccination. This strategy has not been evaluated in different groups of immunocompromized patients. We conducted a prospective, randomized study to compare the humoral response upon standard intramuscular influenza vaccination with the response upon reduced-dose intradermal vaccination in patients treated with anti-tumor necrosis factor (TNF)-alpha, human immunodeficiency virus (HIV)-infected patients, hematologic stem cell transplantation (HSCT) patients, and healthy controls. METHODS In total 156 immunocompromized patients and 41 healthy controls were randomized to receive either 0.5mL of the 2005/2006 trivalent influenza vaccine intramuscular or 0.1mL intradermal. Humoral responses, determined by hemagglutination inhibition assay, were measured before and 28 days postvaccination. Geometric mean titers (GMTs) and protection rates (PRs) are reported as primary outcomes, adverse events as a secondary outcome. RESULTS Reduced-dose intradermal vaccination leads to similar GMTs and PRs, within all tested groups, compared to the standard intramuscular vaccination. Healthy controls yielded significantly better GMTs and PRs than immunocompromized patients. Local skin reactions after intradermal vaccination occurred less frequent and were milder in immunocompromized patients than in healthy subjects and were predictive for a positive vaccination outcome for individual subjects. CONCLUSIONS Intradermal influenza vaccination is a feasible alternative for standard intramuscular vaccination in several groups of immunocompromized patients, including those treated with anti-TNF, HIV-infected patients and HSCT patients. The occurrence of a local skin reaction after intradermal vaccination is predictive of a response to at least one of the vaccine antigens.

Abstract
For patients with immune disorders, the risk of infection during travel depends on the cause and severity of the immune disorder and the type of travel. Immunocompromised travellers experience more severe effects of illness than those without immune disorders. Some risks can be reduced or avoided by taking adequate precautions and, in some cases, modifying travel plans. Ensuring adequate medication use during the trip requires careful planning prior to travel. Regarding vaccination, immunocompromised travellers may have an impaired ability to generate antibodies; live attenuated vaccines are often contraindicated. The treating physician must take a proactive role when an immunocompromised patient indicates that he or she plans to travel. Protocols developed by the Dutch National Coordination Centre for Travellers Health (LCR) provide practical advice regarding a number of situations. Provided that they are given proper individualised advice, there is little concrete evidence to suggest that these patients should not travel anywhere they wish.

Abstract
OBJECTIVES The effect of anti-tumour necrosis factor (TNF) therapy on the antibody responses to vaccines is the subject of ongoing debate. Therefore, we investigated the effect of the three currently available anti-TNF agents on influenza vaccination outcomes in a patient population with long-standing disease. METHODS In a prospective cohort study, we assessed the antibody response upon influenza vaccination in 112 patients with long-standing autoimmune disease treated with immunosuppressive medication either with anti-TNF (etanercept, adalimumab or infliximab; n = 64) or without anti-TNF (n = 48) and a control group of 18 healthy individuals. Antibody responses were determined by haemagglutination inhibition assay, before and 4 weeks after vaccination. RESULTS The proportion of individuals with a protective titre (>or=40) after vaccination was large (80-94%) and did not significantly differ between the three groups. Post-vaccination geometric mean antibody titres against influenza (A/H3N2 and B) were significantly lower in the 64 patients treated with anti-TNF compared with the 48 patients not receiving anti-TNF, and the healthy controls. CONCLUSIONS The antibody response to influenza vaccination in patients treated with anti-TNF is only modestly impaired. The proportion of patients that achieves a protective titre is not significantly diminished by the use of TNF blocking therapies.

Abstract
BACKGROUND Therapeutic drug monitoring (TDM) is being applied for a number of antiretroviral agents. Little is known about the use of TDM for atazanavir. METHODS This is a retrospective cohort analysis on the use of TDM of atazanavir at three clinical sites in The Netherlands. Patients were divided into three groups: (i) all patients with evaluable data of plasma atazanavir concentrations and its relationship with hyperbilirubinaemia; (ii) patients who started atazanavir without documented evidence of protease inhibitor (PI) mutations; (iii) patients who started atazanavir with documented evidence of PI mutations. The genotypic inhibitory quotient (GIQ) was calculated by dividing the mean atazanavir plasma trough concentration by the number of PI mutations. RESULTS A total of 108 patients were included; 70 (65.8%) were using atazanavir/ritonavir (300/100 mg once daily). No significant relationship was observed between atazanavir plasma trough concentration and antiviral response in patients starting atazanavir without PI mutations (group 2; n = 82). In contrast, a significant relationship was observed between atazanavir GIQ and treatment response in patients starting atazanavir while having PI mutations (group 3; n = 26). The cut-off value for GIQ most predictive of virological failure was 0.23 mg/L/mutation: patients (n = 8) with a GIQ equal to or below this value had 50% virological failure whereas patients (n = 18) with a GIQ above 0.23 mg/L/mutation had only 11% virological failure (chi(2): P = 0.030). Atazanavir plasma trough concentrations were significantly related with the occurrence of increased total bilirubin concentrations. CONCLUSIONS TDM of atazanavir might be beneficial for patients with documented PI resistance or patients with hyperbilirubinaemia.

Abstract
A 44-year-old woman suffered fever, headache and meningism during a summer stay in a region of central Italy where sand-fly fever is endemic. A few days after returning to the Netherlands, she appeared mentally and physically slow but had no fever. Because of the possibility of viral meningitis an examination of the cerebrospinal fluid (CSF) was carried out. This revealed a cell count of 1074/3 cells. Toscana virus antibodies of the IgG and IgM subclass were detected in two respective serum samples and in the CSF. This led to the diagnosis 'Toscana virus meningo-encephalitis'. Toscana virus is classified amongst the sandfly fever virus group. These viruses are transmitted by sand flies (Phlebotomus species) which reside in humid areas around the Mediterranean. Toscana virus is the main cause of viral meningoencephalitis in some areas of central Italy and possibly in southern Spain. The patient recovered within a few days without antiviral therapy. Toscana virus meningo-encephalitis should be included in the differential diagnosis of holidaymakers with neurological symptoms returning from the Mediterranean.

Abstract
BACKGROUND HIV-infected patients responding to HAART can show a diverse spectrum of symptoms caused by inflammatory reaction. The pathogenesis of this phenomenon, called immune restoration disease (IRD), is unclear. This study describes the spectrum of IRD and analyses the immunological and clinical parameters that could be related to its development. METHODS In a retrospective, matched case-control study, 17 HIV-infected individuals who developed inflammatory symptoms < 12 months after initiation of HAART were included. HIV-infected controls were matched for age, gender and CDC classification. Factors included in the analysis were: CD4+ and CD8+ cell counts, deltaCD4+ and deltaCD8+, CD4/CD8 ratios, HIV-1-RNA load (VL), AVL and the number of CDC events prior to HAART. RESULTS The median time after initiation of HAART and developing IRD (n = 17) was 72 days (range 2-319). In nine cases (53%) a mycobacterial infection was identified as the underlying cause. HAART was started at a mean CD4+ count (+/- SD) of 55 x 10(6) /l (+/- 59) and 85 x 10(6) /l (+/- 78.0) for cases and controls, respectively (p = 0.13). After initiation of HAART, the CD4+ count showed a 10.6 fold increase at the onset of IRD in the cases and a 2.7 fold increase in the controls in an equal period of time (p = 0.020). The other parameters analysed did not differ significantly between cases and controls. CONCLUSION We conclude that the risk of developing IRD is associated with a high-fold increase in CD4+ lymphocytes. In this study, mycobacteria are the pathogens most frequently associated with IRD.

Abstract
We investigated the humoral (antigen-specific immunoglobulin isotypes, IgG subclasses, and avidity maturation) and cellular (antigen-specific in vitro proliferation) immune response in 18 healthy adult volunteers, following a primary and a single booster vaccination with the T-cell dependent neoantigen rabies administered at a 3-months interval. The IgG antibody titer showed a mean 31-fold increase (range 3-154) 4 weeks after the first vaccination and a memory response was observed after booster vaccination, i.e. high IgG titers, switch from IgM to IgG and IgA and increased antibody avidity. All healthy adults showed a rabies-induced proliferative response with a mean stimulation index of 45 (range 3.5-200) after in vitro stimulation of PBMC obtained at 4 weeks after booster vaccination. The results obtained in this study provide a frame of reference for the interpretation of specific immune responses to the T-cell dependent neoantigen rabies in patients suspected of a primary or secondary immunodeficiency. Humoral and cellular immune responses to the rabies neoantigen provide complementary information on the condition of the immune system of an individual. Five patients diagnosed with a combined immunodeficiency were vaccinated using the same protocol and showed a number of abnormalities, either in the humoral or the cellular immune response to the rabies neoantigen.

Abstract
BACKGROUND The soft-gel capsule (sgc) of saquinavir has been developed in order to improve the poor oral bioavailability of the original hard-gel capsules. However, in a Dutch study population using saquinavir-sgc plasma levels were lower than expected. We hypothesised that this was caused by differences in the amount of fat in the meals of the study populations. METHODS 8-h steady-state plasma curves after observed ingestion of 1200 mg saquinavir-sgc were recorded, concomitantly with a normal breakfast (600 kcal, 33% fat) on the first day, and a high-fat breakfast (1040 kcal, 54% fat) on the second day. Additionally, a comparison was made between saquinavir hard-gel capsules and saquinavir-sgc with or without grapefruit juice (n = 1). Furthermore, a comparison between saquinavir-sgc and ritonavir + saquinavir-sgc 400/400 mg bid was made (n = 1). RESULTS Although saquinavir exposure was improved by fat, grapefruit juice or ritonavir, exposure to saquinavir for all recorded curves was lower than expected. A large proportion of trough concentrations was below the efficacy threshold. CONCLUSION Intake of squinavir-sgc with high-fat meals or grapefruit juice may improve the pharmacokinetic profile. However, plasma concentrations may then still be lower than expected and insufficient for good antiviral efficacy. Probably the only way to reach adequate saquinavir concentrations is by combining saquinavir with ritonavir.

Abstract
INTRODUCTION With the introduction of HAART, the HIV-1 has turned from a lethal into a chronic infection in the majority of patients. In homosexual populations, 20% of HIV-1 infected patients suffer from a chronic HBV infection, which may eventually lead to complications of the liver disease because of prolonged survival. Lamivudine is effective in reducing both HIV-1 and HBV viral replication. However, resistance for lamivudine may complicate the course of the HBV disease in HIV-1-infected patients. We, therefore, conducted a retrospective study in HIV-1-HBV co-infected patients on lamivudine therapy. PATIENTS AND METHODS All HIV-1-HBV co-infected patients who were treated with lamivudine for over 6 months in five major referral clinics in The Netherlands with HBV DNA above 2.0 x 10(5) geq ml(-1) at baseline, were evaluated. Retrospectively, the course of HBV DNA in available serum samples was established. If HBV DNA was detectable with the sensitive PCR-assay, YMDD-analyses of the polymerase gene of the hepatitis B virus was executed with the INNO-LiPA-DR-strip. RESULTS Forty-six patients were evaluated. The median level of HBV DNA at start of lamivudine therapy was 1.31 x 10(9) geq ml(-1) (range 3.5 x 10(5) - 2.0 x 10(10), n=43). Of three patients no baseline sample was available, but since HBV DNA was still above 2.0 x 10(5) geq ml(-1) at week 3, 7 and 11, these patients were included. Median duration of lamivudine therapy was 97 weeks (range 27-263). The percentage of detected mutations was 25 and 52% at 1 and 2 years, respectively. Twenty-two patients ultimately developed a mutation. Both baseline Body Mass Index (BMI) and the decrease in CD4 cell count as a time dependent factor were significantly related to the emergence of mutations. In 10 out of 12 evaluated patients, HBV DNA levels returned to baseline level or even above baseline level after the development of mutant virus. One patient (5%) developed a flare of serum transaminases (ALT>10 x ULN) 24 weeks after first detection of variant virus. CONCLUSION There is a linear time-dependent appearance of HBV mutations for lamivudine in our population. In a minority of patients (5%), development of a mutation was followed by a significant elevation of serum transaminases. A decline in CD4 cell count, which may indicate less response to HAART, induces a faster emergence of mutations and close surveillance of HBV co-infected patients on therapy may be indicated due to the prolonged survival of HIV-1 patients.

Abstract
The antibody production by HIV-infected adults after two vaccinations with conjugated pneumococcal vaccine (CPV) and consecutive vaccination with polysaccharide pneumococcal vaccine (PPV) was studied. Thirty days after the second CPV, the geometric mean antibody concentrations (GMC) against pneumococcal polysaccharide serotypes (PPS) 6B, 14 and 19F were significantly lower in the group HIV-infected individuals with <200x10(6)/l CD4(+) T lymphocytes (group 1) than in the group with >/=200x10(6)/l CD4(+) T lymphocytes (group 2) and healthy controls. Thirty days after PPV vaccination the GMC against PPS 6B, 14, 19F and 23F in group 1, and against 6B and 19F in group 2, were significantly lower compared with healthy controls. Both in HIV-infected and in healthy individuals who received CPV and PPV the postvaccination GMC against PPS 14, 19F and 23F were higher compared with historical controls who were not previously immunized with CPV but only received PPV. We conclude that the antibody response to CPV is impaired in HIV-infected individuals. Higher antibody concentrations were achieved in HIV-infected and healthy individuals after sequential vaccination with CPV and PPV compared with PPV vaccination alone.

Abstract
In a consecutive 3-year study the antibody response after immunization with influenza vaccine of a cohort of HIV-infected adults was studied. The haemagglutination-inhibiting (HAI) antibody titres after vaccination correlated with the number of CD4(+) T lymphocytes (p<0.001), the prevaccination antibody titres (p<0.001), and the proliferative response to anti-CD3 (p<0.001). Severely impaired antibody responses were observed in HIV-infected individuals with CD4(+) T-lymphocyte counts < or =100x10(6)/l. Significantly higher prevaccination antibody titres were observed in healthy controls in the 2nd or 3rd year of vaccination, but not in HIV-infected individuals. Annually repeated vaccination of HIV-infected individuals did not lead to higher postvaccination antibody titres. Annual vaccination of HIV-infected individuals with CD4(+) T-lymphocyte counts exceeding 100x10(6)/l seems to be worthwhile, although it may not be expected to render the same level of protection against influenza as in non-infected individuals.

Abstract
We studied the production of IgG antibodies against eight pneumococcal polysaccharide serotypes (PPS) 1, 4, 6B, 9V, 14, 18C, 19F and 23F after vaccination of 50 HIV-infected adults with 23-valent Pneumovax((R))23 and the course of the antibodies against four PPS during the following years. Mean antibody concentrations against PPS 18C, 19F and 23F were sigificantly lower in the patients with CD4(+)-lymphocyte counts <200x10(6)/l than in healthy controls; mean antibody concentrations against PPS 1, 4, 9V, 6B and 14 were similar in HIV-infected individuals and controls. Although it has been assumed that polysaccharides induce a T-cell-independent immune response, our results indicate that some PPS are T-cell-independent type 2 antigens. The rates of decline of mean antibody concentrations in HIV-infected individuals and in healthy controls were similar during 5 y after vaccination. However, as a consequence of the low postvaccination antibody concentrations against several PPS, within 3 y after vaccination most HIV-infected individuals had antibody concentrations below the level which is assumed to be required for protection.

Abstract
In human immunodeficiency virus type 1 (HIV-1) infection, functional activities of T lymphocytes are impaired. Analogous to tumor-infiltrating T lymphocytes from cancer patients, in whom poor proliferative responses are associated with fewer zeta molecules, this study compared expression of CD3zeta molecules by T lymphocytes from HIV-infected persons and healthy controls. Flow cytometry and immunoblotting revealed significantly diminished zeta expression by CD3, CD4, and CD8 T lymphocytes from AIDS patients but not from persons without AIDS. zeta-mRNA levels were also decreased in cells from AIDS patients. CD3zeta expression correlated significantly with CD4 cell counts and HIV-1 RNA levels; impaired expression of CD3zeta molecules appeared to be reversible upon virus load reduction following highly active antiretroviral treatment (HAART). Thus, reduced expression of CD3zeta molecules by T lymphocytes from HIV-infected persons correlates with disease status. Investigations into CD3zeta expression by subpopulations of peripheral T lymphocytes and by T lymphocytes in lymphoid tissues will contribute to the understanding of immune reconstitution of HIV-infected patients following HAART.

Abstract
Infections with Salmonella species, including Salmonella typhi, are more frequently observed in HIV-infected individuals than in healthy individuals. HIV-infected individuals were vaccinated with polysaccharide vaccine against Salmonella typhi (Typhim-Vi) which is assumed to be a T-cell-independent antigen. We found that the antibody response in patients with < 200 x 10(6)/l CD4+ T lymphocytes was significantly lower compared with patients with > or = 200 x 10(6)/l CD4+ T lymphocytes and healthy controls. The antibody response after vaccination with the polysaccharide salmonella Vi-antigen was correlated with the number of CD4+ T lymphocytes and therefore Typhim-Vi can be considered to be a T-cell-independent type 2 antigen. The results of this study indicate that after vaccination the proportion of HIV-infected individuals with protective antibody concentrations against Salmonella typhi will be lower than in healthy controls.

Abstract
OBJECTIVE To compare efficacy and tolerability of saquinavir soft gelatin capsule (SQV-SGC) formulation and indinavir, both given as part of a triple drug regimen containing zidovudine and lamivudine, in HIV-1-infected individuals. DESIGN Randomized, open label, multicentre study. PATIENTS A total of 70 patients who were antiretroviral-naive and who had a CD4 cell count < 500 x 10(6)/I and/or > 10000 HIV RNA copies/ml plasma and/or HIV-related symptoms. Subjects were assigned randomly to zidovudine 200 mg three times per day plus lamivudine 150 mg twice per day plus either SQV-SGC 1200 mg three times per day (SQV-SGC group) or indinavir 800 mg three times per day (indinavir group). Data are presented for all patients up to week 24. RESULTS Mean baseline CD4 cell counts (+/- SE) were 301+/-29 x 10(6) cells/l and 310 +/-43 x 10(6) cells/l in the SQV-SGC and indinavir groups, respectively. The log10 median baseline HIV RNA load was 5.00 copies/ml in the SQV-SGC group and 4.98 copies/ml in the indinavir group. No difference in antiretroviral effect between the treatment arms could be demonstrated. Intention-to-treat analysis (last observation carried forward [LOCF]) at week 24 revealed that RNA levels decreased to < 50 copies/ml in 74.3% of patients in the SQV-SGC group and in 71.4% of the patients in the indinavir group (P = 0.78). In the on-treatment analysis the proportion of patients < 50 copies/ml at week 24 was 88.0% in the SQV-SGC group and 84.6% in the indinavir group (P = 0.725). Intriguingly, the mean increase of CD4 cells in the first 24 weeks was 162+/-20 x 10(6) cells/l in the SQV-SGC group and 89+/-21 x 10(6) cells/l in the indinavir group (P = 0.01), but preliminary data indicate that this difference in CD4 cell count gain may disappear after 24 weeks of treatment. Both regimens were generally well tolerated. CONCLUSION During the first 24 weeks of the study, we found no difference in antiviral potency between the indinavir group and the SQV-SGC group. A significantly higher CD4 response in the SQV-SGC group was observed.

Abstract
In human immunodeficiency virus (HIV)-infected individuals the amount of antibodies formed after vaccination with T-cell-dependent recall antigens such as tetanus toxoid is proportional to the peripheral blood CD4(+) T-lymphocyte counts. To investigate whether the immunoglobulin G (IgG) subclass distribution and avidity of the antibodies produced after vaccination are affected as well, we gave 13 HIV-infected adults with low CD4(+) T-lymphocyte counts (<200 x 10(6)/liter; group I), 11 HIV-infected adults with intermediate CD4(+) T-lymphocyte counts (>/=200 x 10(6)/liter; group II), and 5 healthy controls booster immunizations with tetanus toxoid. The prevaccination antibody concentrations against tetanus toxoid were similar in the HIV-infected and healthy adults. After vaccination the total IgG and the IgG1 anti-tetanus toxoid antibody concentrations were significantly lower in group I than in group II and the controls. The avidity of the IgG1 anti-tetanus toxoid antibodies formed by HIV-infected adults was within the range for healthy controls, irrespective of their CD4(+) T-lymphocyte counts.

Abstract
BACKGROUND Current antiretroviral treatment can induce significant and sustained virological and immunological responses in HIV-1-infected persons over at least the short- to mid-term. OBJECTIVES In this study, long-term immune reconstitution was investigated during highly active antiretroviral therapy. METHODS Patients enrolled in the INCAS study in The Netherlands were treated for 102 weeks (range 52-144 weeks) with nevirapine (NVP) + zidovudine (ZDV) (n = 9), didanosine (ddl) + ZDV (n = 10), or NVP + ddl + ZDV (n = 10). Memory and naïve CD4+ and CD8+ T cells were measured using CD45RA and CD27 monoclonal antibodies (mAb), T-cell function was assayed by CD3 + CD28 mAb stimulation, and plasma HIV-1 RNA load was measured by ultra-direct assay (cut-off < 20 copies/ml). RESULTS Compared to both double combination regimens the triple combination regimen resulted in the most sustained increase in CD4+ T cells (change in CD4+, + 253 x 10(6) cells/l; standard error, 79 x 10(6) cells/l) and reduction of plasma HIV-1 RNA. In nine patients (31%) (ddl + ZDV, n = 2; NVP + ddl + ZDV, n = 7) plasma HIV-1 RNA levels remained below cut-off for at least 2 years. On average, these long-term virological responders demonstrated a significantly higher increase of naïve and memory CD4+ T cells (P = 0.01 and 0.02, respectively) as compared with patients with a virological failure, and showed improved T-cell function and normalization of the naïve; memory CD8+ T-cell ratio. However, individual virological success or failure did not predict the degree of immunological response. T-cell patterns were independent of baseline CD4+ T-cell count, T-cell function, HIV-1 RNA load or age. Low numbers of naïve CD4+ T cells at baseline resulted in modest long-term naïve T-cell recovery. CONCLUSIONS Patients with prolonged undetectable plasma HIV-1 RNA levels during antiretroviral therapy do not invariably show immune restoration. Naïve T-cell recovery in the setting of complete viral suppression is a gradual process, similar to that reported for immune recovery in adults after chemotherapy and bone marrow transplantation.

Abstract
BACKGROUND Highly active antiretroviral therapy (HAART) effectively suppresses replication of HIV and is accompanied by an increase in CD4+ T lymphocytes. Whether the increase in CD4+ T lymphocytes in the blood is a reflection of a reconstitution of the immune functions is unknown. We investigated the recovery of the humoral immune response during HAART after immunization with T-cell-dependent influenza vaccine. METHODS Forty-one men and three women infected with HIV and treated with HAART, and 15 healthy hospital staff members were immunized with trivalent influenza subunit vaccine. Antibody titres were determined by haemagglutination inhibiting assay in sera obtained before and 30 days after immunization. Lymphocyte subsets were determined in blood samples taken at the time of vaccination. RESULTS In all HIV-infected individuals, treatment with HAART caused a median reduction of 2.3 log10 in HIV-1 load. The median increase of CD4+ T lymphocytes after initiation of HAART was 170 x 10(6)/l. The antibody response to influenza antigens was proportional to the number of memory CD4+ T lymphocytes in the blood at the time of vaccination. When a group of patients and healthy controls with approximately similar CD4+ T-lymphocyte counts were considered, the antibody titres after vaccination for influenza strain H1N1 and influenza B did not differ between patients and controls (P=0.12). Vaccination of patients with a CD4+ T-lymphocyte count of < 200 x 10(6)/l (mean 85 x 10(6)/l) before the start of HAART and with a mean of 282 x 10(6)/l CD4+ T lymphocytes at the time of vaccination as a result of HAART, demonstrated a substantial antibody response whereas patients with a CD4+ T lymphocyte count of < 200 x 10(6)/l (mean 56 x 10(6)/l) not treated with HAART (historical controls), and vaccinated with a similar influenza vaccine, failed to induce an antibody response. CONCLUSION The present findings demonstrate a recovery of the humoral immune response to influenza antigens in HIV-infected individuals treated with HAART. This indicates that functional improvement of antigen specific CD4+ T helper cell reponses occurs.

Abstract
Interleukin-12 (IL-12) is a cytokine that promotes cell-mediated immunity to intracellular pathogens by inducing type 1 helper T cell (TH1) responses and interferon-gamma (IFN-gamma) production. IL-12 binds to high-affinity beta1/beta2 heterodimeric IL-12 receptor (IL-12R) complexes on T cell and natural killer cells. Three unrelated individuals with severe, idiopathic mycobacterial and Salmonella infections were found to lack IL-12Rbeta1 chain expression. Their cells were deficient in IL-12R signaling and IFN-gamma production, and their remaining T cell responses were independent of endogenous IL-12. IL-12Rbeta1 sequence analysis revealed genetic mutations that resulted in premature stop codons in the extracellular domain. The lack of IL-12Rbeta1 expression results in a human immunodeficiency and shows the essential role of IL-12 in resistance to infections due to intracellular bacteria.

Abstract
In the present study the role of granulocyte-macrophage colony stimulating factor (GM-CSF) in the reduced toxoplasmastatic activity of monocytes was investigated in patients with acquired immunodeficiency syndrome (AIDS). The secretion of GM-CSF by non-stimulated monocytes and by Toxoplasma gondii-infected monocytes from AIDS patients did not differ from that of healthy individuals. Furthermore, GM-CSF was not detected in sera from AIDS patients and healthy individuals. However, upon stimulation with lipopolysaccharide (LPS), monocytes from AIDS patients released significantly more GM-CSF than those from healthy individuals. Incubation of monocytes from AIDS patients with polyclonal antibodies against GM-CSF restored their inhibitory activity against T. gondii. On the basis of the present and earlier results the putative mechanism of reduced toxoplasmastatic activity of monocytes from AIDS patients may be as follows: upon stimulation with human immunodeficiency virus (HIV) the increased synthesis of GM-CSF by monocytes stimulates the production of prostaglandin E2 (PGE2) which, in turn, impairs the toxoplasmastatic activity of these cells.

Abstract
A neutralization enzyme immunoassay (N-EIA) was used to determine the neutralizing serum antibody titers to influenza A/Taiwan/1/86 (H1N1) and Beijing/353/89 (H3N2) viruses after vaccination of 51 human immunodeficiency virus (HIV) type 1-infected individuals and 10 healthy noninfected controls against influenza virus infection. Overall, the N-EIA titers correlated well with the hemagglutination-inhibition (HAI) titers that were observed in the same samples in a previous study (F. P. Kroon, J. T. van Dissel, J. C. de Jong, and R. van Furth, AIDS 8:469-476,1994). The N-EIA appeared to be more sensitive than the HAI test. Significantly more fourfold or higher rises in N-EIA titer and higher mean N-EIA titers occurred in HIV-infected individuals with > or =200 CD4+ cells per microl than in those with <200 CD4+ cells per microl.

Abstract
OBJECTIVE Amphotericin B deoxycholate initial therapy and fluconazole maintenance therapy is the treatment of choice for AIDS-associated cryptococcal meningitis. However, the administration of amphotericin B is associated with considerable toxicity. A potential strategy for reducing the toxicity and increasing the therapeutic index of amphotericin B is the use of lipid formulations of this drug. DESIGN AND METHODS HIV-infected patients with cryptococcal meningitis were randomized to treatment with either liposomal amphotericin B (AmBisome) 4 mg/kg daily or standard amphotericin B 0.7 mg/kg daily for 3 weeks, each followed by fluconazole 400 mg daily for 7 weeks. During the first 3 weeks, clinical efficacy was assessed daily. Mycological response was primarily evaluated by cerebrospinal fluid (CSF) cultures at days 7, 14, 21 and 70. RESULTS Of the 28 evaluable patients, 15 were assigned to receive AmBisome and 13 to receive amphotericin B. Baseline characteristics were comparable. The time to and the rate of clinical response were the same in both arms. AmBisome therapy resulted in a CSF culture conversion within 7 days in six out of 15 patients versus one out of 12 amphotericin B-treated patients (P = 0.09), within 14 days in 10 out of 15 AmBisome patients versus one out of nine amphotericin B patients (P = 0.01), and within 21 days in 11 out of 15 AmBisome patients versus three out of eight amphotericin B patients (P = 0.19). When Kaplan-Meier estimates were used to compare time to CSF culture conversion, AmBisome was more effective (P < 0.05; median time between 7 and 14 days for AmBisome versus > 21 days for amphotericin B). AmBisome was significantly less nephrotoxic. CONCLUSIONS A 3-week course of 4 mg/kg AmBisome resulted in a significantly earlier CSF culture conversion than 0.7 mg/kg amphotericin B, had equal clinical efficacy and was significantly less nephrotoxic when used for the treatment of primary episodes of AIDS-associated cryptococcal meningitis.

Abstract
A prospective study of antibody production by adults infected with human immunodeficiency virus (HIV) after vaccination with tetanus toxoid-conjugated Haemophilus influenzae type b (Hib) vaccine was conducted. Concentrations of antibodies to the two immunogenic components of the vaccine (i.e., polyribosylribitolphosphate [PRP] and tetanus toxin) were determined. Individuals were divided into three groups according to the CD4+ T lymphocyte count: group 1, < or =100 x 10(6)/L; group 2, 101-300 x 10(6)/L; and group 3, >300 x 10(6)/L. After vaccination, concentrations of IgM and IgG antibodies to PRP were significantly lower in group 1 than in the other patient groups and controls. A CD4+ T lymphocyte count of <100 x 10(6)/L and an impaired proliferative response of lymphocytes to monoclonal antibody to CD3 were independently associated with a less than threefold increase in concentrations of IgG antibody to PRP. Analysis of IgG subclasses demonstrated that the production of IgG1 antibodies was predominantly affected. Postvaccination concentrations of antibody to tetanus toxin were significantly lower in group 1 than in group 3 and controls. Both prevaccination and postvaccination concentrations of antibody to tetanus toxin were not correlated with the magnitude of the response of antibody to PRP. We conclude that HIV-infected individuals with CD4+ T Iymphocyte counts of <100 x 10(6)/L demonstrate an impaired antibody response after vaccination with conjugated Hib vaccine.

Abstract
Gastrointestinal stromal cell tumours (GIST) of the small intestine are rare malignancies. Recently, an association of Epstein-Barr virus (EBV) with malignant stromal cell tumour in young people with AIDS and past EBV infection has been described. We describe a 33-year-old heterosexual male with asymptomatic human immunodeficiency virus (HIV) infection who had had an EBV infection in the past and who presented with an EBV-negative GIST. The association between EBV and malignant stromal cell tumours in young people with AIDS could not be reconfirmed in our adult patient. The relationship between EBV and malignant stromal cell tumours in AIDS patients and the possible pathogenetic role of EBV remains to be established, at least in adults.

Abstract
Parvovirus B19 infection may cause chronic anemia in human immunodeficiency virus (HIV)-infected hosts. Small-scale studies and case reports have suggested that parvovirus B19 infection is a significant cause of anemia in HIV-infected patients. We studied single serum samples from 317 consecutive HIV-infected patients with use of parvovirus B19-specific serology and polymerase chain reaction for detection of viral DNA. Anemia was noted in 176 patients (55.5%); 126 (39.9%) had < 0.10 x 10(9) CD4+ cells/L. In this study group, 191 (60.3%) of the patients were positive for parvovirus B19 IgG. Seroprevalence rates did not differ between patients with low and higher CD4+ cell counts or between anemic and nonanemic patients. Parvovirus B19 DNA was detected in none of the sera. In a control group of 226 healthy male blood donors, the seroprevalence of parvovirus B19 IgG was 68.1%; two IgG-positive sera also contained parvovirus B19 DNA. This study demonstrates that chronic parvovirus B19 infection should not be considered a frequent cause of anemia in HIV-infected individuals.

Abstract
Three patients with a cellular immunodeficiency were treated with rifabutin, clarithromycin and ethambutol for a disseminated infection with Mycobacterium avium-intracellulare complex (MAC). The patients developed uveitis, sometimes in combination with a transient rash, arthralgia, arthritis, jaundice and pseudojaundice. It seems likely that these reactions were caused by rifabutin, alone or together with other drugs such as clarithromycin. These adverse reactions probably depend on the dose, metabolism and excretion of the drug. Inhibition of cytochrome P450 seems to be an important mechanism.

Abstract
Pneumocystis carinii pneumonia (PCP) is an infection of immunocompromised patients. The purpose of our study was to estimate the risk of PCP in renal transplant recipients in relation to number, timing, and type of rejection treatments and to cytomegalovirus (CMV) infection. In a case-control study, 15 renal transplant recipients with proven PCP were compared with 95 controls. The relative risks of PCP for 1, 2, and > or = 3 rejection treatments vs. no such treatment were 1.7 (95% CI, 0.2-12.5), 4.8 (95% CI, 0.9-25.5), and 9.5 (95% CI, 1.6-56.4). The relative risk of PCP for renal transplant recipients with negative pretransplantation CMV serology was 3.2 (95% CI, 1.0-10.2), and for the combination of recipient-negative and donor-positive pretransplantation CMV serology it was 5.7 (95% CI, 1.4-22.3). The relative risk of PCP for patients with CMV infection was 5.0 (95% CI, 1.6-15.8). The risk of PCP in renal transplant recipients was positively related to the number but not the timing or type of rejection treatments. The risk of PCP was also increased in cases of CMV infection, irrespective of the number of rejection treatments.

Abstract
The objective of our study was to determine the production of nitric oxide (NO) in patients infected with human immunodeficiency virus (HIV) and its relation to cellular immunity, activation of mononuclear phagocytes and the amount of circulating virus. Therefore, serum nitrate, the stable metabolite of NO, the number of peripheral CD4+ T-lmphocytes, serum neopterin, plasma HIV-RNA and HIV-DNA in peripheral blood mononuclear cells of afebrile HIV-infected patients were determined. Serum nitrate levels were significantly (p = 0.002) increased in HIV-infected patients (median 37 microM, range 13-137 microM, n = 77) in comparison to healthy subjects (median 28 microM, range 21-40 microM, n = 17). Serum nitrate levels did not correlate with the number of CD4+ T-lymphocytes (r = 0.05, p > 0.05). Serum nitrate levels were positively correlated with neopterin (r = 0.36, p = 0.05, n = 30), the amount of HIV-DNA in peripheral blood mononuclear cells (r = 0.63, p < 0.001, n =27) and plasma HIV-RNA levels (r = 0.35, p = 0.08, n = 27). A possible explanation of our findings is that HIV induces the production of NO by means of activated mononuclear phagocytes.

Abstract
BACKGROUND Pneumocystis carinii pneumonia (PCP) occurs in immunocompromised patients without the acquired immunodeficiency syndrome (AIDS). There has been an increasing yearly number of cases of PCP in our patients without AIDS. OBJECTIVE To determine the nature of the underlying disorder and previous immunosuppressive treatment in patients with PCP without AIDS. METHOD A study of the charts of 78 such patients admitted to our hospital from 1980 through 1993. RESULTS The number of PCP cases per year increased during the period studied. All patients had an underlying disorder, either hematologic malignancy (49%), solid organ tumor (4%), vasculitis or other immunologic disorder (22%), or they had undergone renal transplantation (17%) or bone marrow transplantation (9%). Previous immunosuppressive medication consisted of prednisone or other corticosteroids in 72 (92%) of 78 patients, cytotoxic drugs in 55 (71%) of 78 patients, both in 50 (64%) of 78 patients, and none in one patient. Quantification of previous corticosteroid treatment showed a large variability among patients. The overall mortality rate for patients was 35% (27/78). Mortality was significantly higher in patients with a concomitant pulmonary infection (P = .01), an underlying disorder other than that which resulted in renal transplantation (P = .03), mechanical ventilation (P < .001), previous chemotherapy (P = .04), as well as previous cyclophosphamide treatment (P = .01). A trend toward a higher mortality in patients with previous corticosteroid use was detected (P = .06). CONCLUSION Pneumocystis carinii pneumonia may complicate a variety of immunocompromised states, with considerable mortality. Pneumocystis carinii pneumonia occurred at all levels of immunosuppression; no threshold level could be defined.

Abstract
A prospective study of antibody production by adults infected with human immunodeficiency virus (HIV) after vaccination with T lymphocyte-dependent diphtheria toxoid, tetanus toxoid, and inactivated trivalent poliovirus vaccine was conducted. Individuals were divided into three groups according to CD4+ T-lymphocyte count: group 1 had a count of < or = 100-300 x 10(6)/L; and group 3, > 300 x 10(6)/L. After vaccination, 61%, 70%, and 73% of the individuals in groups 1, 2, and 3, respectively, developed protective titers of antibody to diphtheria toxin; the mean postvaccination antibody titer of HIV-infected individuals was significantly lower than that of healthy controls not infected with HIV. Furthermore, the mean titers of antibodies to tetanus toxin and poliovirus were significantly lower in HIV-infected individuals with CD4+ lymphocyte counts of < 300 x 10(6)/L than in controls. Of the HIV-infected vaccinees, 83%-100% were protected against tetanus and 78%-100% against polio. We conclude that HIV-infected individuals with CD4+ lymphocyte counts of < 300 x 10(6)/L have an impaired (secondary) antibody response after receipt of T lymphocyte-dependent vaccines.

Abstract
OBJECTIVE To establish the role of prostaglandin E2 (PGE2) formed and released by monocytes and monocyte-derived macrophages (MDM) in the reduced toxoplasmastatic activity of these cells. DESIGN Determination of PGE2 levels in the serum of AIDS patients, the release of PGE2 by monocytes and MDM from AIDS patients, the toxoplasmastatic activity of these cells and the effect of indomethacin, an inhibitor of PGE2 synthesis, on this cell function. SETTING Laboratory of Cellular Immunology of the Department of Infectious Diseases, University Hospital, Leiden. PARTICIPANTS Twenty-six AIDS patients. Healthy blood donors served as controls. RESULTS The concentration of PGE2 in the serum from AIDS patients was significantly higher compared with serum from controls. Non-stimulated monocytes and lipopolysaccharide-stimulated monocytes and MDM from AIDS patients released significantly more PGE2 than corresponding cells from the controls. The proliferation of Toxoplasma gondii in monocytes and MDM from AIDS patients was significantly higher than in the respective cells from controls. Preincubation of these cells with indomethacin resulted in a decreased proliferation of T. gondii in non-activated monocytes and MDM and in interferon-gamma-activated MDM from AIDS patients. Preincubation of monocytes from healthy donors with PGE2 resulted in a dose-dependent increase of Toxoplasma proliferation which confirms that PGE2 can reduce the toxoplasmastatic activity of monocytes. CONCLUSION PGE2 is involved in the reduced toxoplasmastatic activity of monocytes and MDM from AIDS patients.
