Abstract
A prospective, multicenter pharmacovigilance study was carried out to evaluate the safety of a new 7-dose treatment schedule of subcutaneous immunotherapy as opposed to the conventional 13 doses normally recommended. The study was carried out in 14 centers and included 261 patients (children and adults) with respiratory allergic disease due to sensitization to mites (Dermatophagoides pteronyssinus and/or farinae). A total of 2290 doses were administered under the direct supervision of the participating specialists. One hundred and ten reactions in 63 patients (24.1%) were recorded, representing 4.8% of the total doses administered. Most of the reactions (98) were local. Only 12 were systemic (0.5% of the administered doses) and occurred in 10 patients (3.8% of the sample). Ten reactions reverted quickly with rescue medication. The maintenance dose had to be lowered in one patient and another patient was withdrawn from the study after suffering two asthmatic crises after two consecutive doses. In view of the results obtained, we can conclude that the new schedule shows an acceptable tolerance profile and does not present a greater risk of reactions than the conventional scheme of 13 doses using an identical extract. Moreover, the new schedule represents substantial savings in the number of doses and visits required to reach the maintenance dose.

Abstract
Chronic hepatitis B and C represent a leading cause of morbidity and mortality among human immunodeficiency virus (HIV)-infected patients worldwide. New treatment options against both hepatitis B (HBV) and C (HCV) viruses have prompted us to update previous recommendations for the management of coinfected individuals. Fifteen topics (nine related to HCV, five to HBV and one to both viruses) were selected for this purpose. A panel of Spanish experts in the field was invited to review these areas and propose specific recommendations, which were scored according to the Infectious Disease Society of America (IDSA) grading system. These guidelines represent a comprehensive and updated overview on the management of hepatitis B and C in HIV-infected patients.

Abstract
INTRODUCTION There are many studies that analyze the clinical course of multiple sclerosis (MS), but only a few of them observed patients from their first episode. We report a MS series of patients longitudinally evaluated from the onset of the disease and compare outcome between immunosuppressive treatment and non-treatment groups. PATIENTS AND METHODS Patients were included when their follow-up was at least three years and serial examination was available. Poser's criteria were used for diagnosis. We measured neurological impairment according to Kurtzke's expanded disability status scale (EDSS). RESULTS Fifty-five MS patients were followed-up. Forty-six had clinically defined and nine clinically probable MS. Thirty-three patients had relapsing-remitting, 11 had secondary-progressive and 11 had primary-progressive MS. Mean age of onset of the disease was 31.1 years and mean duration of follow-up was seven years. Pyramidal weakness and sensory symptoms were the most common initial manifestations. Median time to reach EDSS-3 and EDSS-6 from onset was 4.5 and 7.5 years, respectively. From a total of 23 patients with follow-up of 10 or more years, 11 (48 %) had benign MS. The average time from onset of MS to secondary-progressive was 6.1 years. There were no significant differences between treatment and non-treatment patients. CONCLUSION Longitudinal studies starting from early clinical course of MS are most useful in determining its semeiology, clinical pattern and outcome. Our results call for caution in initiating early immunosuppressive or immunomodulatory therapy.

Abstract
The aim of this study was to test the presence of separate sperm subpopulations, with specific motility characteristics, in stallion ejaculates by using a computer-assisted semen motility analysis (CASA) system. Motility data were analyzed with a hierarchical clustering of variables based on a correlation or covariance matrix to select like parameters of sperm motility descriptors that better explain the kinetics of spermatozoa. The statistical analyses clustered the whole motile sperm population in both fresh and 24 h stored ejaculates into four separate groups. There were significant differences in the distribution of the four subpopulations (P < 0.001) as well as in the total sperm number and the percentage of total motility (P < 0.01) in fresh semen among the five stallions tested. Our results show that separate subpopulations of spermatozoa with different motility characteristics coexist in stallion ejaculates. These subpopulations were maintained, although with a less-progressive motion pattern, after 24 h of storage. The study of subpopulations in ejaculates that have confirmed fertilizing capacity showed that the majority of the motile spermatozoa in these ejaculates are included in a subpopulation with high progressive motility and low linearity, and the ejaculates with proven fertility that have a total sperm count > or = 20 x 10(9) spermatozoa/ejaculate show all of their motile sperm included in this subpopulation. Our results show that the use of the CASA system is a relatively simple approach to the study of sperm subpopulation patterns in equine ejaculates.

Abstract
OBJECTIVE To describe the process performed in Catalonia (Spain) to design an information system for monitoring new cases of HIV infection. METHODS A survey was used to evaluate perception of the need for notification of HIV infection by health care professionals (n = 106), as well as their opinions of the various possibilities for the implementation of the notification system. As a result of this evaluation, a specific technical report defining the objectives and technical characteristics of the new notification system was produced. The feasibility of the system in health centres was evaluated through discussions with health care professionals, health authorities and Non-Governmental Organizations, and a second survey was designed to evaluate the use of a personal identification code (PIC) from the individual health card (IHC). This process took plabe between 1998 and 2000. RESULTS A total of 84.5% of the health care professionals believed that HIV notification should be mandatory and confidential; 90.4%, were of the opinion that notification would enable identification of the epidemiological characteristics of infected individualos, and 75% believed that these individuals would have to be identified by name. Finally, 66% of the health care professionals believed that the use of the PIC from the IHC would be feasible as the personal identifier in HIV notification. A final proposal was draw up and 1 January, 2001 was set as the date to initiate the pilot phase of the new HIV notification system. CONCLUSIONS Most of the health care professionals surveyed expressed the need for notification of HIV infection, and for such notification to receive institutional endorsement. They also believed that, as with other diseases of individualized mandatory reporting, notification should be carried out with a single personal identifier. The information obtained from notification of HIV infection is essential for the optimal planning of preventive programs and the provision of health services. The main difficulties observed were that HIV infection has not been included among the diseases of mandatory reporting, as well as the low implantation of the PIC in the hospitals' clinical registries. All the sectors involved have an important role to play in creating the conditions necessary for the notification system of new cases of HIV infection to be feasible and useful.

Abstract
Free-wall myocardial abscess perforation with hemopericardium and sudden death is an extremely infrequent complication of infective endocarditis (IE). We describe a case of Staphylococcus aureus-associated native aortic and tricuspid valve endocarditis complicated by a septic myocardial infarction and abscess formation of embolic origin, with fatal rupture into the pericardium. To our knowledge, only 2 cases of myocardial abscess rupture have previously been reported in relation to IE.

Abstract
There is an increasing proportion of HIV-positive patients exposed to all licensed classes of antiretrovirals, and the response to salvage regimens may be poor. Among over 8500 patients in EuroSIDA, the proportion of treated patients exposed to nucleosides, protease inhibitors (PIs) and non-nucleoside reverse transcriptase inhibitor (NNRTI) increased from 0% in 1996 to 47% in 2001. Four-hundred-and-thirteen patients, who had failed virologically two highly active antiretroviral therapy (HAART) regimens and experienced all three main drug classes, started a salvage regimen of at least three drugs, in which at least one new PI or NNRTI was included. Median viral load was 4.7 log copies/ml [Interquartile range (IQR) 4.2–5.2], CD4 lymphocyte count 150/mm3 (IQR 60–274/mm3) and follow-up 14 months. Of these patients, 283 (69%) subsequently experienced at least a 1 log decline in viral load and 202 (49%) achieved a viral load <500 copies/ml. Conversely, the CD4 count halved from the baseline value in 88 (21%), and 45 (11%) experienced a new AIDS-defining disease. In multivariable analyses, a 1 log viral load reduction was related to baseline viral load [relative hazard (RH) 1.27 per 1 log higher; P=0.008], a previous viral load of less than 500 copies/ml (RH 1.69; P=0.002), more recent initiation of the regimen (RH 1.36 per year more recent; P=0.02), number of new drugs in the regimen (RH 1.20 per drug; P=0.02), time since start of antiretroviral therapy (RH 0.94 per extra year; P=0.035) and time spent on HAART with viral load >1000 copies/ml (RH 0.96 per extra month; P=0.0001). Analysis of factors associated with CD4 count decline and new AIDS disease also indicated improved outcomes in more recent times and a tendency for a better response in those starting more new drugs, but no relationship with the total number of drugs. Outcomes in people starting salvage regimens appear to depend on the number of new drugs started but not on the total number of drugs being used.

Abstract
OBJECTIVES Rash is the most frequent adverse event associated with nevirapine. The use of prednisone has been controversial in this setting. A double-blind placebo-controlled study was performed to evaluate its efficacy in nevirapine-induced rash prevention. DESIGN Multicentered, randomized, double-blind, placebo-controlled clinical trial with prednisone (30 mg/day x 2 weeks). INCLUSION CRITERIA HIV-1 infection; CD4 count >200 cells/mm3; plasma viral load (PVL) <5 log10 copies/ml; nevirapine (200 mg/day x 2 weeks, followed by 200 mg twice daily) plus stavudine and didanosine. Clinical follow-up was performed at 15, 30, and 60 days and thereafter every 2 months. RESULTS In all, 75 evaluable patients were enrolled (39 prednisone/36 placebo). Median baseline CD4 + cell count was 390 cells/mm3 and PVL, 20,200 copies/ml. Overall, nine cases of rash (12.5%) were detected, seven (18%) in the prednisone group and two (5.5%) in the placebo group (odds ratio [OR], 3.85; 95% confidence interval [CI], 0.65-29.3; p =.11). Incidence of moderate-to-severe rashes leading to nevirapine withdrawal was 13.5% (5 of 37) in the prednisone group and 3% (1 of 35) in the placebo group ( p =.2). Median time to rash in both groups was 16 days. Adverse events that motivated withdrawal of therapy appeared in 6 patients from the prednisone group (15.4%) and 3 from the placebo group (8.3%) ( p =.3). CONCLUSION Short-term prednisone administration does not prevent nevirapine rash, but might even increase its incidence.

Abstract
OBJECTIVES To assess virological response in lymphoid tissue and its impact on the durability of response in plasma in HIV-1-infected persons who achieved sustained suppression of plasma viraemia with different antiretroviral regimens. METHODS Consecutive patients on first-line antiretroviral therapy were included if they had a plasma HIV-1 RNA viraemia < 20 copies/ml within the last 6 months and tonsillar tissue accessible for biopsy. First-line therapy contained two nucleoside analogues: alone (2NRTI group, n = 3); plus a HIV-1 protease inhibitor (PI group, n = 11) or plus nevirapine (NVP group; n = 16). Patients were followed until virus was detectable in plasma, they changed therapy or were lost to follow-up. RESULTS Tonsillar HIV-1 RNA could be detected (> 100 copies/mg) in 10 patients: one in the PI group (9%), six (38%) in the NVP group and in all three patients in the 2NRTI group. Primary resistance mutations could be detected in only 2 of these 10 patients. After a median of 9 months after the biopsies, viral suppression in plasma had failed in 6 of these 10 patients whereas failure had only occurred in 1 out of 20 with initially undetectable viral load in lymphoid tissue (P = 0.01; log rank test). CONCLUSIONS In patients with sustained viral suppression in plasma, triple therapy including a HIV-1 protease inhibitor was more potent than triple therapy containing nevirapine or dual therapy with nucleoside analogues to reduce viral burden in lymphoid tissue. A worse response in lymphoid tissue could not be explained by local selection of resistance and was associated with a less durable virological response in plasma.

Abstract
BACKGROUND The duodenal switch (DS) is a variant of the biliopancreatic diversion (BPD), with a vertical subtotal gastrectomy and pylorus preservation. METHODS DS was used to treat morbid obesity in 125 patients, with mean BMI 50, with 65% of the patients super obese (SO). Patients have been followed for an intermediate period. RESULTS The percentage of excess weight loss (%EWL) was > 70% at 1 year, and reached 81.4% at 5 years when 97% of the patients had a %EWL > 50%. Comorbidities were cured or improved in all patients. CONCLUSION DS was very effective for the treatment of the morbid obesity in the SO patients.

Abstract
BACKGROUND Some individuals with chronic HIV-1 infection have discontinued their drug therapy with consequent plasma virus rebound. In a small number of patients, a delayed or absent rebound in plasma virus load has been noted after drug cessation, apparently associated with prior drug interruptions and autologous boosting of HIV-1 specific immune responses. We hypothesized that cyclic structured treatment interruptions structured treatment interruptions (STI) could augment HIV-1 specific immune responses in chronic HIV-1 infection, which might help to control HIV-1 replication off therapy. METHODS We initiated an STI pilot study in 10 antiretroviral treatment-naive HIV-1 chronically infected subjects with baseline CD4 T-cell counts > 500 x 10(6) cells/l and plasma viral load > 5000 copies/ml who received highly active antiretroviral therapy (HAART) for 1 year with good response (plasma viral load < 20 copies/ml for at least 32 weeks). Three cycles of HAART interruption were performed. RESULTS In all of the patients viral load rebounded, but doubling times increased significantly between the first and third stops (P = 0.008), and by the third stop, six out of nine subjects had a virological set-point after a median 12 months off therapy that was lower than baseline before starting HAART (ranging from 0.6 log(10) to 1.3 log(10) lower than baseline) and in four it remained stable below 5000 copies/ml. Those subjects who controlled viral replication developed significantly stronger HIV-1 specific cellular immune responses than subjects lacking spontaneous decline (P < 0.05). During viral rebounds no genotypic or phenotypic changes conferring resistance to reverse trancriptase inhibitors or protease inhibitors was detected, but mean absolute CD4 T-cell counts declined significantly, although never below 450 x 10(6)/l and the mean value at 12 months off therapy was significantly higher than the pre-treatment level (P = 0.004). CONCLUSIONS Our findings suggest that STI in chronic HIV-1 infection might augment HIV-1-specific cellular immune responses associated with a spontaneous and sustained drop in plasma viral load in some subjects but at the potential cost of lower CD4 T-cell counts.

Abstract
OBJECTIVE To study the incidence, etiology, and outcome of pulmonary infiltrates (PIs) in HIV-infected patients and to evaluate the yield of diagnostic procedures. DESIGN Prospective observational study of consecutive hospital admissions. SETTING Tertiary hospital. PATIENTS HIV-infected patients with new-onset radiologic PIs from April 1998 to March 1999. METHODS The study protocol included chest radiography, blood and sputum cultures, serologic testing for "atypical" causes of pneumonia, testing for Legionella urinary antigen, testing for cytomegalovirus antigenemia, and bronchoscopy in case of diffuse or progressive PIs. RESULTS One hundred two episodes in 92 patients were recorded. The incidence of PIs was 18 episodes per 100 hospital admission-years (95% confidence interval [CI]: 15-21). An etiologic diagnosis was achieved in 62 cases (61%). Bacterial pneumonia (BP), Pneumocystis carinii pneumonia (PCP), and mycobacteriosis were the main diagnoses. The incidences of BP and mycobacteriosis were not statistically different in highly active antiretroviral therapy (HAART) versus non-HAART patients. The incidence of PCP was lower in those receiving HAART (p =.011), however. Nine patients died (10%). Independent factors associated with higher mortality were mechanical ventilation (odds ratio [OR] = 83; CI: 4.2-1,682), age >50 years (OR = 23; CI: 2-283), and not having an etiologic diagnosis (OR = 22; CI: 1.6-293). CONCLUSIONS Pulmonary infiltrates are still a frequent cause of hospital admission in the HAART era, and BP is the main etiology. There was no difference in the rate of BP and mycobacteriosis in HAART and non-HAART patients. Not having an etiologic diagnosis is an independent factor associated with mortality.

METHODS The study protocol included chest radiography, blood and sputum cultures, serologic testing for "atypical" causes of pneumonia, testing for Legionella urinary antigen, testing for cytomegalovirus antigenemia, and bronchoscopy in case of diffuse or progressive PIs. RESULTS One hundred two episodes in 92 patients were recorded. The incidence of PIs was 18 episodes per 100 hospital admission-years (95% confidence interval [CI]: 15-21). An etiologic diagnosis was achieved in 62 cases (61%). Bacterial pneumonia (BP), Pneumocystis carinii pneumonia (PCP), and mycobacteriosis were the main diagnoses. The incidences of BP and mycobacteriosis were not statistically different in highly active antiretroviral therapy (HAART) versus non-HAART patients. The incidence of PCP was lower in those receiving HAART (p =.011), however. Nine patients died (10%). Independent factors associated with higher mortality were mechanical ventilation (odds ratio [OR] = 83; CI: 4.2-1,682), age >50 years (OR = 23; CI: 2-283), and not having an etiologic diagnosis (OR = 22; CI: 1.6-293). CONCLUSIONS Pulmonary infiltrates are still a frequent cause of hospital admission in the HAART era, and BP is the main etiology. There was no difference in the rate of BP and mycobacteriosis in HAART and non-HAART patients. Not having an etiologic diagnosis is an independent factor associated with mortality.

Abstract
This study sought to determine the clinical and echocardiographic features, surgical approach, and outcome of patients with infective endocarditis complicated with aortocardiac fistulas among a series of 346 consecutive cases between 1988 and 1998. Nine patients (2%) were found to have aortocardiac fistulas complicating infective endocarditis caused by highly pyogenic pathogens (4 patients had ruptured abscesses of the right sinus of Valsalva, 3 had fistulous communications from the left coronary sinus, and 1 had a fistulized abscess in the noncoronary sinus). Mortality in these patients was very high (55%), even when surgery was attempted early in the course of the disease and reconstructive procedures were implemented.

Abstract
The introduction of highly active antiretroviral therapy with protease inhibitors in 1996 has changed the morbidity and mortality of acquired immune deficiency syndrome patients. Therefore, the aetiologies and prognostic factors of human immunodeficiency virus (HIV)-infected patients with life-threatening respiratory failure requiring intensive care unit (ICU) admission need to be reassessed. From 1993 to 1998, we prospectively evaluated 57 HIV patients (mean+/-SEM age 36.5+/-1.3 yrs) admitted to the ICU showing pulmonary infiltrates and acute respiratory failure. A total of 21 and 30 patients were diagnosed as having Pneumocystis carinii and bacterial pneumonia, respectively, of whom 13 and eight died during their ICU stay (p=0.01). Both groups of patients had similar age, Acute Physiology and Chronic Health Evaluation (APACHE) II score, and severity in respiratory failure. The number of cases with bacterial pneumonia admitted to ICU decreased after 1996 (p=0.05). Logistic regression analysis showed that (APACHE) II score >17, serum albumin level <25 g.(-1), and diagnosis of P. carinii pneumonia were the only factors at entry associated with ICU mortality (p=0.02). Patients with bacterial pneumonia are less frequently admitted to the intensive care unit after the introduction of highly active antiretroviral therapy with protease inhibitors in 1996. Compared to the previous series, it was observed that the few Pneumocystis carinii pneumonia patients that need intensive care still have a bad prognosis.

Abstract
UNLABELLED This research comprised a pilot open prospective clinical study comparing T-cell subset reconstitution in antiretroviral-naive patients, after 12 months of HAART when treatment was initiated in early stages (ES; n = 18) of infection versus advanced stages (AS; n = 20). CONTROL GROUP 10 healthy HIV-negative individuals. Immunophenotypic markers were evaluated before and after 6-and 12-months' therapy. Functional assays were performed in one subset. RESULTS Viral load (VL) was < 200 copies/ml in all patients. Median percentages of CD4+ pretherapy were 33% and 6%, respectively, in the ES and AS groups, increment after 12 months of therapy was +15% and +13% respectively. Only the ES group achieved normal values. Declines of CD8+ percentage were significantly higher in the ES (-18%) than in the AS group (-2%). CD4+ memory and naive cells in the ES group were similar to those of controls before treatment and did not change after therapy. In contrast, CD4+ memory and naive cells in the AS group did not reach normal levels despite treatment. In the ES group, there was a significant increment in CD8+ naive cells (+8%) and a decrement in CD8+CD38+ cells (-17%), both populations reached values close to normal, whereas these subsets remained far from normal in the AS group. Improvement of lymphoproliferative response after therapy was observed in both groups. One patient in the ES group showed positive LPR against p24 after treatment. After 12 months' highly active antiretroviral therapy, only those who began such therapy in ES disease reached values within the range of healthy controls. To achieve a more complete immunologic reconstitution, early initiation of potent antiretroviral therapy should be recommended.

Abstract
OBJECTIVES To evaluate the safety and effectiveness of once-daily didanosine and nevirapine plus twice-daily stavudine versus twice-daily administration of all three drugs. METHODS This open-label, randomized, multicentre study enrolled 94 antiretroviral-naive patients with chronic HIV infection, CD4+ cell counts > 500 x 10(6) cells/l, and viral loads > 5000 copies/ml. Patients were treated with either 40 mg stavudine (twice daily) plus 400 mg didanosine (once daily) and 400 mg nevirapine (once daily) or 40 mg stavudine (twice daily) plus 200 mg didanosine (twice daily) and 200 mg nevirapine (twice daily). RESULTS After 12 months, 68% of patients who received twice-daily didanosine and nevirapine had viral loads < 200 copies/ml in the intention-to-treat and 79% in the on-treatment analysis, respectively. The corresponding values for patients treated with didanosine and nevirapine, taken once-daily, were 73 and 85%. The percentages of patients in each group with viral loads < 5 copies/ml at 12 months were 40% (once daily ) and 45% (twice daily) for the intention-to-treat analysis. Five of 11 patients (45%) with plasma viral loads < 5 copies/ml at 12 months had detectable virus in tonsillar tissue. Genotypic resistance to nevirapine was noted in seven of the 14 patients with detectable viral load at month 12. Mean changes in CD4+ cell counts for patients treated with stavudine plus once- or twice-daily didanosine and nevirapine were 154 and 132 x 10(6) cells/l, respectively. Treatment was interrupted due to adverse events in seven patients (8%) (four who received once-daily didanosine and nevirapine and three treated with twice-daily doses). CONCLUSIONS The combination of twice-daily stavudine plus once-daily didanosine and nevirapine was as safe and well tolerated as twice-daily administration of all three agents. Both regimens were equally effective in reducing viral loads and in increasing CD4+ cell counts.

Abstract
OBJECTIVE To compare ease of recording and reliability of ultrasonographic approaches used to time fetal heart atrial and ventricular contractions. METHODS Seventeen consecutive fetuses seen at our fetal cardiology unit for possible fetal cardiac arrhythmia were included in this study. The same ultrasonographer obtained M-mode tracings of atrial and ventricular free walls, atrial wall and opening of the aortic valves, a peak of the mitral valve, and the opening of the aortic valves; and Doppler signals of flow-velocity waveforms in the outflow tract of the left ventricle and simultaneous flow-velocity waveforms in the aorta and superior vena cava. The outcome measures were rate of successful attempts and intra- and interobserver reliability coefficients. RESULTS Valid recordings were made for all patients with one M-mode (atrial and ventricular free walls) and two Doppler (intraventricular, superior vena cava, and ascending aorta) approaches. Atrioventricular intervals were significantly longer with M-mode compared with Doppler ultrasonography. Reliability coefficients were excellent (at least 0.89) for all intraobserver measurements. Comparisons of atrioventricular and ventriculoatrial interval measurements made by two observers gave the following intraclass correlation coefficients (95% confidence interval): atrioventricular = M-mode: 0.87 (0.79, 0. 91), left ventricular outflow: 0.93 (0.89, 0.96), superior vena cava-aorta: 0.98 (0.97, 0.99); ventriculoatrial = M-mode: 0.79 (0.67, 0.87), left ventricular outflow: 0.97 (0.95, 0.98); superior vena cava-aorta: 0.99 (0.98, 0.99). CONCLUSION Fetal atrioventricular intervals measured indirectly from M-mode or Doppler tracings were equally reliable when measured by the same observer; the Doppler approaches had better correlation between measurements made by two different observers.
