Abstract
This study evaluates the frequency and causes of dolutegravir (DTG) discontinuation along 5 years of follow-up, in both antiretroviral treatment (ART)-naive and experienced people living with HIV (PLWH). This is a prospective multi-center cohort study enrolling PLWH on DTG from July 2014 until November 2020. DTG-durability was investigated using the Kaplan-Meier survival curve. The Cox proportional-hazards model was used for estimating the hazard ratio (HR) of DTG discontinuation for any cause, and for adverse events (AEs). Nine hundred sixty-three PLWH were included, 25.3% were women and 28.0% were ART-naive. Discontinuations for any causes were 10.1 [95% confidence interval (95% CI) 8.9-11.5] per 100 person-years, similar in most regimens, with the apparent exception of tenofovir alafenamide/emtricitabine+DTG (p < 0.0001). In the multivariable Cox regression model, non-Caucasian ethnicity, age ≥50 years, and lower estimated glomerular filtration rate (eGFR) were associated with a higher probability of DTG interruption. The incidence rate of virological failure was 0.4 (95% CI 0.2-0.7) per 100 person-years, while the estimated discontinuation rate for AEs was 4.0 (3.2-4.9) per 100 person-years. Thirty-four DTG interruptions were due to grade ≥3 events (10 central nervous system, 6 hypersensitivity, 3 renal, 3 myalgia/asthenia, 3 abdominal pain, 2 gastrointestinal, and 7 other events). People with lower body mass index, age ≥50 years, and lower eGFR were at higher risk of AEs, while dual combinations were protective (HR 0.41 compared with abacavir/lamivudine/DTG, 95% CI 0.22-0.77). In this prospective observational study, we found high DTG durability and a low rate of virological failures. Dual therapies seemed protective toward AEs and might be considered, when feasible, a suitable option to minimize drug interactions and improve tolerability.

Abstract
The determination of sediment toxicity is challenging due to site-specific factors affecting pollutants distribution and bioavailability, especially when contamination levels are close to expected non-effect concentrations. Different lines of evidence and sensitive tools are necessary for a proper toxicity risk assessment. We examined the case study of the Toce River (Northern Italy), where past industrial activities determined Hg, DDT and As enrichment in sediments. A triad approach comprising chemical, ecotoxicological and ecological analyses (benthic invertebrates) was carried out for risk assessment of residual contamination in river sediments. A "blank" site upstream from the industrial site was selected to compare the other sites downstream. Sediment, water and benthic invertebrate samplings were carried out following standard protocols. Results emphasized that despite the emissions of the industrial site ceased about 20years ago, sediments in the downstream section of the river remain contaminated by Hg, DDT and As with concentrations exceeding Threshold Effect Concentrations. A chronic whole-sediment test with Chironomus riparius showed decreased development rate and a lower number of eggs per mass in the contaminated sediments. Benthic community was analyzed with the calculation of integrated (STAR_ICMi) and stressor-specific metrics (SPEARpesticide and mean sensitivity to Hg), but no significant differences were found between upstream and downstream sites. On the other hand, multivariate analysis (partial Redundancy Analysis and variation partitioning) emphasized a slight impact on invertebrate community, accounting for 5% variation in taxa composition. Results show that legacy contaminants in sediments, even at low concentrations, may be bioavailable and possibly toxic for benthic invertebrates. At low concentration levels, sensitive and site-specific tools need to be developed for a proper risk analysis.

Abstract
This work deals with the evaluation of the aqueous concentrations of dissolved reactive phosphorus (DRP), total phosphorus (TP), and ammonium nitrogen (N-NH4) in surface water by means of direct online instrumentation. A portable, submersible, and automated analyzer designed to measure dissolved and total nutrient concentrations characterized by miniaturization of the entire analytical process was tested against laboratory methods. A total number of 36 water samples of different origin (i.e., rain, river, lake, and sewage waters) were analyzed and used in the comparison of DRP, TP, and N-NH4 data. Raw data were distributed in a broad range of concentrations: 5-299 μg P/L for DRP, 7-97 μg P/L for TP, and 11-332 μg N/L for N-NH4. Regression analysis underlined a high significant correlation between the measures of the probe and those of the laboratory (0.6 < R 2 < 0.9; p < 0.001) and pointed out the effectiveness of the new instrument in representing a broad range of nutrient concentrations.

Abstract
OBJECTIVES Methotrexate (MTX) resistance is defined on the basis of the human chorionic gonadotropin (hCG) curve. The aim of this study was to identify low-risk non-metastatic patients with gestational trophoblastic neoplasia (GTN) who can achieve resolution by continuing MTX treatment despite a transient hCG plateau. METHODS Before starting chemotherapy, 24 patients with FIGO Stage I GTN underwent transvaginal ultrasonography with power Doppler in order to identify myometrial lesions (areas of increased echogenicity and increased power Doppler signal). Ultrasound response to chemotherapy was defined when myometrial lesions decreased in echogenicity, Doppler signal or size. When ultrasound response occurred, despite chemoresistance defined by hCG values, MTX treatment was continued. RESULTS MTX was continued in three out of seven chemoresistant patients because ultrasound suggested response to MTX. All three of these patients achieved a complete response, thus nearly halving the MTX-resistance rate. CONCLUSION Among patients who are candidates for second-line treatment on the basis of hCG, ultrasound may identify those in whom further MTX administration can induce a delayed complete response.

Abstract
The impact of hypertension in the pregnancies from autoimmune patients is not unequivocally defined. We have prospectively followed 168 pregnancies from 135 patients from four Italian centres to verify the potential impact of hypertension in the antiphospholipid syndrome (APS). The rate of preeclampsia, mean neonatal weight and gestational age at delivery were significantly lower in patients with both APS and hypertension than in patients with hypertension or APS alone. This information may be relevant for counselling and care of these patients.

Abstract
Summary The aim of the study was to evaluate the cardiovascular risk factors associated with subclinical carotid atherosclerosis in antiretroviral therapy-naïve HIV-infected patients. The HERMES (HIV Exposure and Risk of Metabolic Syndrome) study enrolled therapy-naïve patients attending hospitals in the Italian coordination group for the study of allergies and HIV infection (CISAI [Coordinamento Italiano per lo Studio Allergia e Infezione da HIV]) in 2007. It was designed to identify metabolic syndrome (MS) and cardiovascular risk factors. The present analysis is a nested cross-sectional study with a subset of patients examined by carotid ultrasonography. Consecutive antiretroviral therapy-naïve HIV patients attending the facilities involved in the CISAI were included. Their 10-year probability of cardiovascular events was calculated using the Framingham Risk Score (FRS) and three other cardiovascular algorithms (the Global Framingham Risk Score – GFRS, ‘Progetto Cuore’ and ‘SCORE’). Vascular age was estimated using a new model derived from GFRS and was compared with chronological age. The diagnosis of MS was based on the National Cholesterol Education Programme and International Diabetes Federation (IDF) definitions. Subclinical atherosclerosis was determined as ultrasound carotid intima-media thickness >0.9 mm. Out of 140 patients enrolled in the HERMES study by the four centres participating in the nested study, a total of 72 (51.4%) subjects, with no overt cardiovascular disease, were examined using carotid ultrasonography. The median age was 40 years, 79.2% men. The vascular age was 7.6 years higher than the chronological age. The factors associated with subclinical atherosclerosis were age (P < 0.0001), vascular age (P = 0.0002), body mass index (P = 0.003), waist circumference (P = 0.0002), MS (IDF definition, P = 0.004) and all the cardiovascular (CV) models (FRS, P = 0.01, GFRS, P = 0.002, Progetto Cuore, P = 0.018, SCORE, P = 0.03). Independent of other significant factors, waist circumference was significantly associated with pathological results (P = 0.007). The GFRS (area under the receiver-operating characteristic curves, 0.78; P < 0.001) had slightly better predictive accuracy than the other three CV models (FRS, areas under the curve [AUC] = 0.71, P = 0.003; Progetto Cuore, AUC = 0.74, P = 0.0005; SCORE, AUC = 0.77, P < 0.0001); 55% of patients at intermediate risk (6–20%) had subclinical carotid lesions. Subclinical carotid lesions had a highly significant direct association with all the CV risk predictors. The GFRS and vascular age were highly predictive. We recommend a carotid ultrasonographic examination at least among HIV patients with GFRS >6% or with an elevated waist circumference.

Abstract
AIM Twin pregnancy has to be considered a risk pregnancy. One of its most controversial aspects is delivery. There is no agreement on the following topics: gestational age at term (GA), mode of delivery, use of epidural analgesia or oxytocic acceleration, impact of chorionicity and amnionicity. The aim of this study was to develop a twin delivery management protocol. METHODS A retrospective study over a cohort population of 481 twin deliveries that occurred in the Department of Obstetrics of the San Raffaele Hospital of Milan (Italy) from 1996 to 2007 was conducted, and the results were compared with those present in literature. RESULTS Management of twin pregnancies that exceed the 37 week is controversial. There is an inclination towards fixing bichorionic and monochorionic pregnancy terms at 38 and 35 weeks respectively. In our case history, 73.8% of monochorionic and 15% of bichorionic pregnant women delivered after the 35 and 38 week respectively, without repercussions on the neonatal outcome. A longer gestational age appears to decrease the occurrence of lower Apgar scores and neonatal morbidity. This study, which exclusively considered twin pregnant women with both fetuses in cephalic presentation eligible for a vaginal delivery, did not find any significant differences in neonatal outcome among the types of deliveries. Moreover, the authors observed that the average maternal blood loss in cesarean section (CS) is significantly greater than that of vaginal deliveries. CONCLUSIONS In consideration of its safety for mother and fetuses, vaginal delivery of two cephalic fetuses at 38 and 35 weeks for bichorionic and monochorionic pregnancies respectively may be considered as a valid alternative to elective cesarean section.

Abstract
An increased fetal DNA concentration in maternal plasma has been observed in placental pathological conditions associated with hypertension and preeclampsia. To confirm these data, we performed real-time quantitative PCR on the SRY gene in a group of physiological and pathological male-bearing pregnancies. In 78 physiological pregnancies, fetal DNA concentration in maternal plasma was 20.7, 13.4, 23.6, and 74.8 genome-equivalents (g.e.)/mL during the first, second, and third trimesters and at term, respectively. In 10 preeclamptic women, fetal DNA concentration ranged from 59.3 to 615.2 g.e./mL (median: 332.9). In 7 women with preeclampsia and IUGR (intrauterine growth retardation), fetal DNA ranged from 96.5 to 859 g.e./mL (median: 146.8). In 4 women with IUGR and hypertension, fetal DNA ranged from 34 to 473.5 g.e./mL (median: 142.4). In 3 patients with IUGR, fetal DNA ranged from 168.6 to 519.7 g.e./mL (median: 308.1). In 2 patients with IUGR and HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome, fetal DNA concentration ranged from 105 to 394.1 g.e./mL (median: 249.7). Four women who developed preeclampsia some weeks later showed fetal DNA levels within the physiological range. These data suggest that increased fetal DNA concentrations might represent a valuable marker of placental abnormalities and suggest that this rise may precede clinical manifestation of preeclampsia by only a few weeks.

Abstract
Risk factors in the development of adverse reactions in HIV-1-infected patients treated with highly active antiretroviral therapy (HAART) containing protease inhibitors are poorly understood. To identify predictors of protease inhibitor-associated adverse events, we are conducting a prospective, cohort, multicenter study on HIV-positive patients starting treatment with at least one protease inhibitor. Rate ratios (RR) of adverse events were calculated, and logistic regression was used to adjust simultaneously for the potentially confounding effects of selected variables, according to the Cox model. A total of 1477 patients have been enrolled up to April 2000, having an average age of 37.1 years (SD +/- 8.1); 1066 (72.2%) were male. Where risk factors for HIV infection are concerned, the distribution was as follows: 48.1% intravenous drug users, 31.6% heterosexual contacts, 16.2% homosexual males and 0.7% blood transfusion. Average CD4+ lymphocyte count at enrollment was 265 cells/mmc (SD +/- 201). Average follow-up time is equal to 17.8 months (range 1-32). The risk of developing adverse reactions is significantly increased in female patients, older patients, hemophiliac subjects and in subjects with hepatitis. Patients treated with ritonavir, the association ritonavir-saquinavir HGC, stavudine and efavirenz have significantly increased incidence of adverse reactions in PI-containing regimens; conversely, saquinavir HGC, zidovudine and lamivudine use was associated with a lower risk of developing adverse reactions.

Abstract
PURPOSE To establish the exact cause and effect relationship between protease inhibitors (PIs) and adverse events. MATERIALS AND METHOD Prospective, cohort, multicenter study on HIV-positive patients who are beginning treatment with a PI. Causal relationships are evaluated using the RUCAM algorithm. RESULTS Since the beginning of the study 1207 patients have been enrolled. Average time of observation is 10.7 months. To date, 784 adverse events have been observed, distributed as follows: excluded 3.8%, improbable 18.5%, possible 41.3%, probable 30.1%, and highly probable 6.3%. Saquinavir shows a statistically significant difference in the rate of non-correlated events with respect to other groups. CONCLUSIONS Over 20% of adverse events during PI treatment are shown to be non-correlated to these drugs. Saquinavir shows the highest rate of non-correlated events.

Abstract
OBJECTIVE To assess the probability that protease inhibitor (PI) therapy might be discontinued because of adverse events (AE) and to evaluate the incidence rate of adverse reactions during PI treatment. DESIGN A prospective cohort, multicenter study on HIV-positive patients starting treatment with at least one PI. SETTING Ten departments of infectious diseases in Northern Italy. PATIENTS A total of 1207 patients who started PI therapy in September 1997 and were consecutively observed up to April 1999. MAIN OUTCOME MEASURES Adverse reactions following initiation of PI therapy, and time to therapy discontinuation due to AE. RESULTS During the study period, 35.9% patients presented adverse reactions of any grade, whereas 9.7% presented at least one serious AE. After 12 months of treatment, the percentage of patients who had interrupted treatment was 36% of ritonavir-treated patients, 14.2% of those treated with indinavir, 13.6% of ritonavir-saquinavir hard gel capsules (HGC)-treated patients, and 8.5% and 2.1%, respectively, for those treated with nelfinavir and saquinavir HGC. Women and patients with hepatitis experienced a significantly greater number of adverse events compared with other categories. Gastrointestinal events were more frequently observed in patients treated with either ritonavir alone or in combination with saquinavir HGC, as well as in patients receiving nelfinavir, although in this group serious events were rare. Here again, neurologic, metabolic, and hepatic toxicity occurred more frequently in ritonavir and ritonavir-saquinavir HGC treated patients. Allergic reactions were more often observed in patients receiving nelfinavir. Indinavir-treated patients presented the highest incidence of renal toxicity. CONCLUSION Ritonavir is the drug associated with the largest number of reactions, which appear during the first few months of treatment. Saquinavir HGC and nelfinavir are the best tolerated drugs in a clinical setting.

Abstract
Chillblain Lupus Erythematosus (CL) of Hutchinson is a subtype of Lupus Erythematosus characterized by erythematous lesions symmetrically distributed on the face, nose, fingers and toes, knees and heels. The lesions are induced by cold, damp climates. A number of patients affected by CL eventually develop features of Systemic Lupus Erythematosus (SLE). We report here 7 patients, all but one affected by SLE, with chilblain cutaneous lesions on their hands, feet and face. The onset of CL preceded the diagnosis of SLE, from 1 to 10 years in 3 cases, it was concurrent in one case and was subsequent in the other 2 cases. Six out of the seven patients referred typical Raynaud's phenomenon and one had acrocyanosis. CL lesions developed and were aggravated by the cold during autumn and winter, they improved during summer. Skin biopsy performed in 5 patients from the lesions showed, on histology, a typical pattern of alterations with granular deposits at the dermo-epidermal junction on direct immunofluorescence. Laboratory findings showed: ANA and anti-SSA/Ro were detected in all the patients, anti-SSA/Ro were isolated in 4 patients and associated with anti-Sm in one case, anti-U1 RNP in one case and with anti-Sm and anti-RNP in a third case. Complement consumption was observed in 5 patients, anti-dsDNA in the six patients with SLE, hypergammaglobulinemia in 4 and rheumatoid factor in one. The fine specificity of anti-SSA/Ro as determined by immunoblotting using a human spleen extract as a substrate, showed: anti-60kD and anti-52 kD in two sera, anti-60kD isolated in 2 sera, anti-52kD isolated in one serum (from the patient without SLE) while 2 sera did not blotted. In conclusion, our study confirms the previous report of anti-SSA/Ro antibodies in association with CL. This clinical and serologic association widens the spectrum of cutaneous disease that is associated with antibodies to SSA/Ro to include conditions such as to SCLE, hypergammaglobulinemic purpura and neonatal lupus.

Abstract
OBJECTIVE Assess alpha-tocopherol serum levels in a population of pregnant women affected by different hypertensive disorders. METHODS Alpha-tocopherol serum levels were determined by high-pressure liquid chromatography in 177 third-trimester pregnant women: 63 affected by gestational hypertension, 69 by preeclampsia, 26 by chronic hypertension, and 19 normotensive controls. In 39 out of the 158 hypertensive patients, pregnancy was complicated by intrauterine growth retardation (IUGR). RESULTS Alpha-tocopherol serum levels did not show any significant difference among gestational hypertensive, preeclamptic, chronic hypertensive patients, and controls. A significant reduction of alpha-tocopherol levels was observed when we compared patients with IUGR and patients with a normally grown fetus. Such significant reduction was maintained when we analyzed the different classes of hypertension. CONCLUSIONS The reduction of antioxidant nutrients and, in particular, of alpha-tocopherol is not a feature of preeclampsia and seems better correlated with the presence of placental insufficiency, rather than maternal disease.

Abstract
In a prospective longitudinal study, 130 primigravidae at risk for preeclampsia were examined and plasma sampling performed in 45 of them. Plasma thrombomodulin (pTM) was sequentially measured at weeks 12, 24 and 32 of gestation and after delivery in 20 primigravidae who developed either mild preeclampsia (n = 8) or gestational hypertension (n = 12) between weeks 32 and 39 of gestation and in 25 (age-matched) primigravidae who had uneventful pregnancies. pTM elevations were not observed until week 32 in uneventful pregnancies, but were present by week 24 (p = 0.002) in patients who later developed hypertensive complications. A net individual pTM increase > or = 4.2 ng/ml between weeks 12 and 24 (more than 8 times that of normotensive primigravidae) and/or pTM level > or = 47.5 ng/ml at week 32 predicted the development of hypertensive complications with 80% accuracy. Serial pTM determinations can be useful to select pregnancies who may benefit from early pharmacological intervention.

Abstract
To determine the accuracy of antenatal renal pelvis measurement as a screening tool for renal anomalies we reviewed the antenatal ultrasounds performed at our institution over 1 year. Renal pelvis dilation was found in 3.8% of pregnancies followed by our obstetrics department. In nine (17.6%) infants renal anomalies were detected after birth, the remaining cases remained unchanged or resolved over a 1-year postnatal follow-up. In our series dilations of less than 10 mm in utero resolved in the first months after birth while dilations greater than 15 mm were all associated with malformations of the genitourinary tract. The choice of the most appropriate follow-up for dilations between 10 and 15 mm remains an issue because these dilations can herald renal anomalies.

Abstract
OBJECTIVE To assess the incidence of non-Hodgkin's lymphoma (NHL) and estimate the relative risk (RR) of developing lymphoproliferative complications in a large population of Italian patients with Sjögren's syndrome (SS) and to ascertain if any difference exists between the north and centre-south of Italy. METHODS Differential relative risks of NHL were obtained by comparing the number of observed cases with cases identified on the basis of age-sex-time specific incidence rates extracted from regional cancer registries. RESULTS Among the 331 patients with SS studied, 9 cases of NHL occurred, while no lymphoid malignancy appeared in patients with overlapping connective tissue disease (secondary SS) or in males with primary SS. As the number of NHL cases identified on the basis of the rate in the cancer registries would have been 0.27, the RR is 33.3 (p < 0.001). The incidence rate of NHL in Italian patients with SS is about 5.1/1000 person-years. 5.4/1000 per year in the north of the country and 4.8/1000 per year in the centre-south. The relative risks are, respectively, 34.7 and 32.5. CONCLUSION Italian patients with primary SS have increased risk of developing NHL. In this group, the absence of a significant difference between the north and the centre-south of Italy contrasts with the higher incidence of NHL in the general population of northern regions and strengthens the direct connection between primary SS and NHL.

Abstract
OBJECTIVE To define the accuracy of preoperative evaluation of prognostic factors in detecting patients with low risk of node metastasis in which different surgical approaches can be proposed. SUBJECTS Seventy-five patients with a histologically proven endometrial carcinoma were considered in this study. METHODS All the patients underwent a preoperative evaluation of grading (G), and myometrial invasion (M) by endometrial biopsy and transvaginal ultrasound (TVS). In 41 patients preoperative ploidy of carcinoma cells (P) was determined by flow cytometry. Pre-surgical G, M and P were then compared with surgical specimens. We considered 'low risk', patients with no or moderate myometrial invasion, well-differentiated histological grading and diploid DNA. RESULTS We were able to identify 19/23 (82.6%) low risk cases. Correct identification of high risk patients was obtained in 49/52 (94%) patients. In three low risk patients, correctly diagnosed preoperatively, the final FIGO stage was IIIA (two for adnexal involvement and one for positive peritoneal washing). CONCLUSIONS Our findings suggest that it is possible to detect preoperatively patients with a low risk of node metastasis. Alternative surgical approaches, i.e. vaginal surgery, can be taken into account in such patients.

Abstract
OBJECTIVE To define the accuracy of the umbilical artery Doppler flow velocity waveforms, according to different cut-off values, in predicting adverse perinatal outcomes among fetuses at high risk of hypoxic complications. SUBJECTS Two hundred and sixty-five pregnant women with diagnosis of small for gestational age fetus and/or pregnancy induced hypertension studied in four Italian ultrasound units. METHODS Prospective study. Serial Doppler ultrasound measurements of the umbilical artery were performed. Results were not available for clinical management. Cut-off curves, corresponding to different age-specific centiles of the pulsatility index distribution among pregnancies resulting in healthy newborns, regardless of birthweight, were computed by regression methods. Sensitivity, specificity, positive predictive value and negative predictive value of such cut-off curves, and of absent/reverse end-diastolic flow, in predicting different adverse outcomes were estimated. The adverse outcomes were: perinatal or neonatal death (OUTCOME 1). Death or Apgar<7 at 5' or need for admission to intensive care unit or other hypoxic related abnormalities (OUTCOME 2). Either OUTCOME 2 or birthweight<l0th centile (OUTCOME 3). Both OUTCOME 2 and birthweight<10th centile (OUTCOME 4). RESULTS The best accuracy was in predicting OUTCOMES 1 and 4. Positive predictive value increased strongly with higher cut-off curves while negative predictive value only decreased slightly. For absent/reverse end-diastolic flow, negative predictive value and positive predictive value were respectively 94% and 39% for death, and 81% and 72% respectively for OUTCOME 2. For the 95th centile curve the corresponding figures were 96%, 33% and 84%, 67%. The 60th centile curve had a 85% and 74% sensitivity value for death and OUTCOME 2 respectively, but the corresponding positive predictive values were 18% and 40% only. CONCLUSIONS The findings of an absent end diastolic flow or of pulsatility index values above the 95th centile curve strongly suggest it is time to deliver the fetus. The 60th centile curve is the most suitable to recognize fetuses at risk for abnormal outcome, but early delivery should be avoided because of its low positive predictive value.

Abstract
OBJECTIVE We assessed the reliability of transvaginal ultrasonography in the detection of uterine involvement in cases of gestational trophoblastic tumor, to establish a possible role of this procedure in the management of such neoplasia. STUDY DESIGN Transvaginal ultrasonography was performed in six women with gestational trophoblastic tumor at initial diagnosis, during the cytotoxic course when negative beta-human chorionic gonadotrophin levels were obtained, and within 3 to 6 months after the end of chemotherapy. RESULTS In all cases in which metastatic disease was absent intrauterine localization was easily detected by transvaginal ultrasonography; it appeared as endometrial hypoechoic areas and intramyometrial nodules. Favorable response to chemotherapy was determined by a negative serum beta-human chorionic gonadotropin determination accompanied by the finding of regression of nodules at transvaginal ultrasonography. CONCLUSION Our data support the introduction of transvaginal ultrasonography in the management of gestational trophoblastic tumor.

Abstract
To determine the spectrum of esophageal disease responsible for dysphagia/odynophagia in AIDS patients not responding to current oral antifungals, we studied 49 consecutive patients whose esophageal symptoms failed to improve after a minimum of 3 wk of therapy with oral ketoconazole or fluconazole. An esophageal candidiasis resistant to oral antifungals was the most frequent disease found (22 single infections and four mixed with viruses). Viral esophagitis was identified in 13 cases (eight herpes simplex virus and five cytomegalovirus), and an esophagitis of unknown origin was documented in two patients. Other causes of symptoms included peptic esophagitis (four cases), esophageal stenosis (two cases), and Kaposi's sarcoma of the esophagus (one patient). Most patients with esophageal opportunistic infection experienced prompt relief of symptoms and complete endoscopic resolution on the specific antifungal (amphotericin B or fluconazole iv) or antiviral (acyclovir or gancyclovir iv) therapy, with the exception of those with concomitant fungal and viral infection who responded poorly to treatment. We conclude that most AIDS patients with dysphagia/odynophagia who do not respond to oral antifungals have an opportunistic infection of the esophagus. Nevertheless, specific antifungal or antiviral therapy is worthwhile, because it will eradicate, at least temporarily, the causative pathogens in most such patients.

Abstract
To determine the cumulative incidence of acute upper gastrointestinal bleeding and its effect upon survival in patients with AIDS, 453 consecutive AIDS patients diagnosed in our hospital between June 1985 and March 1989 were followed for a median period of six months (maximum 42 months). The cumulative probability of acute gastrointestinal bleeding was 3% at six months and 6% at 14 months. This event was associated with significantly reduced survival. Independent risk factors for bleeding were: severe thrombocytopenia at the time of diagnosis and non-Hodgkin's lymphoma as the first clinical manifestation of AIDS. The potential causes of bleeding were investigated in all cases by emergency endoscopy or by necropsy examination in those patients whose clinical condition precluded the procedure. In nine of 15 patients, bleeding was due to lesions specifically associated with AIDS, but in the remainder the source of bleeding was not a direct consequence of HIV infection. We conclude that acute upper gastrointestinal bleeding rarely complicates the course of AIDS, but its occurrence is associated with decreased survival. As many of the causes are potentially treatable, a complete diagnostic approach is indicated in these patients, except those who are terminally ill.
