Abstract
BACKGROUND A serum-free, highly purified Vero rabies vaccine (PVRV-NG) has been developed with no animal or human components and low residual DNA content. A phaseII randomized clinical study aimed to demonstrate the non-inferiority of the immune response and assess the safety profile of PVRV-NG versus a licensed human diploid cell culture rabies vaccine (HDCV) in a pre-exposure regimen in healthy children and adolescents in the Philippines. METHODOLOGY Children aged 2-11 years and adolescents aged 12-17 years were randomized (2:1) to receive three injections of either PVRV-NG or HDCV (on day [D] 0, D7 and D28). Rabies virus-neutralizing antibodies (RVNA) were measured at D0, D42 and 6 months after the first injection (month [M] 6). Safety was assessed during the vaccination period and up to 28 days after the last vaccination. Serious adverse events were followed until 6 months after last vaccination. PRINCIPAL FINDINGS 342 healthy participants (171 children and 171 adolescents) were randomized and followed for 6 months after the last dose. All participants in both groups had an RVNA titer ≥ 0.5 IU/ml at D42, demonstrating non-inferiority in seroconversion rate for PVRV-NG versus HDCV. Over 90% of participants had RVNA titer ≥ 0.5 IU/ml at M6. PVRV-NG was well tolerated after each vaccination and up to 6 months following the last dose. There were no major safety concerns during the study, and the type and severity of solicited adverse events was similar for both treatment groups. CONCLUSIONS This study demonstrated the non-inferior immune profile of PVRV-NG compared with HDCV in a pre-exposure setting within a pediatric population. PVRV-NG was well tolerated with no safety concerns. This study is registered at ClinicalTrials.gov (NCT01930357) and EU Clinical Trials Register (2015-003203-30).

Abstract
An inactivated split-virion quadrivalent influenza vaccine (IIV4; Fluzone® Quadrivalent; Sanofi Pasteur) has been available in the US since 2013 and in the Southern Hemisphere since 2015. Here, we describe the results of an open-label, post-licensure trial (WHO Universal Trial Number, U1111-1143-9256) to confirm the immunogenicity and safety of the Southern Hemisphere 2015 formulation of IIV4. Adults 18–60 years of age and > 60 years of age (n = 60 per age group) received a single 0.5-mL intramuscular injection of IIV4. After vaccination, hemagglutination inhibition titers for each strain in IIV4 increased by a geometric mean of at least 10-fold for younger adults and at least 9-fold for older adults. All of the younger adult participants and 98%–100% of the older adult participants had seroprotective titers for each strain. Also, at least 80% of younger adults and 78% of older adults seroconverted or had a significant increase in titer for all four vaccine strains. These post-vaccination immune responses exceeded the criteria of the Committee for Human Medicinal Products former Note for Guidance for influenza vaccines. Finally, no serious adverse events were reported, and no new safety signals were detected. These results confirmed that the Southern Hemisphere 2015 formulation of IIV4 was well tolerated, highly immunogenic, and met the criteria for influenza vaccine immunogenicity and safety.

Abstract
BACKGROUND The best strategy to protect individuals against meningococcal disease is to immunize against multiple serogroups. Immunogenicity, antibody persistence, and safety of the EU-licensed meningococcal ACWY-tetanus toxoid conjugate vaccine (MenACWY-TT) were evaluated in healthy participants aged 11-55 years from the Philippines and Saudi Arabia. METHODS In this phase IIb, open, controlled study, 500 participants were randomised (3:1) to receive one dose of MenACWY-TT or a licensed meningococcal polysaccharide vaccine (Men-PS). Functional antibody responses against meningococcal serogroups A, C, W-135, and Y were assessed by a serum bactericidal antibody assay using rabbit complement (rSBA) at Month 0, Month 1, Year 1, Year 2, and Year 3. Vaccine response was defined as an rSBA titre ≥32 at Month 1 in participants who were seronegative (rSBA titre <8) pre-vaccination and as at least a four-fold increase in titre in participants who were seropositive pre-vaccination. Solicited symptoms were recorded up to Day 4, safety outcomes up to Month 6, and serious adverse events related to vaccination up to Year 3. RESULTS Pre-specified criteria for non-inferiority of MenACWY-TT versus Men-PS were met in terms of rSBA vaccine response and incidence of grade 3 general symptoms. At Month 1, 82.7%-96.3% of MenACWY-TT and 69.7%-91.7% in Men-PS recipients had a vaccine response for each serogroup. At Year 3, ≥99.1% and ≥92.9% of MenACWY-TT recipients retained rSBA titres ≥8 and ≥128, respectively, as compared to ≥86.7% and ≥80.0% in the Men-PS group. Both vaccines had a clinically acceptable safety profile, although injection site redness and swelling were more frequent in MenACWY-TT recipients. CONCLUSIONS These results suggest that MenACWY-TT could protect adolescents and adults against meningococcal disease up to three years post-vaccination.

Abstract
Rabies is a deadly zoonotic disease most often transmitted to humans through a dog bite. Human mortality from endemic canine rabies is estimated by WHO to be around 55,000 deaths annually, with over 31,000 deaths in Asia alone, mostly children. Most of these deaths could be prevented through post-exposure prophylaxis (PEP), including immediate wound washing, rabies immunoglobulin administration and vaccination. Unfortunately, at-risk populations are not well-informed of the risk of rabies and what to do in the event of an animal bite. In order to identify the main gaps in rabies information and better define the most urgent information actions to be undertaken, the Asian Rabies Expert Bureau (AREB) conducted a multicentre, multi-country survey of patients seeking rabies post-exposure prophylaxis in rabies prevention centres from 1 July 2007 to 31 January 2008, in Bangladesh, China, India, Indonesia, Pakistan, the Philippines, Sri Lanka, and Thailand. Questionnaires were completed for 4377 subjects in the eight countries. Data was collected regarding the patient, former rabies exposures, the present wound, rabies exposure management, and rabies awareness. Two major issues were identified where active information of the population could make a difference: the necessity to apply appropriate wound care and to consult the nearest rabies prevention centre as soon as possible.

Abstract
Since the initial description of splenic marginal zone lymphoma (SMZL) in 1992, an increasing number of publications have dealt with multiple aspects of SMZL diagnosis, molecular pathogenesis and treatment. This process has identified multiple inconsistencies in the diagnostic criteria and lack of clear guidelines for the staging and treatment. The authors of this review have held several meetings and exchanged series of cases with the objective of agreeing on the main diagnostic, staging and therapeutic guidelines for patients with this condition. Specific working groups were created for diagnostic criteria, immunophenotype, staging and treatment. As results of this work, guidelines are proposed for diagnosis, differential diagnosis, staging, prognostic factors, treatment and response criteria. The guidelines proposed here are intended to contribute to the standardization of the diagnosis and treatment of these patients, and should facilitate the future development of clinical trials that could define more precisely predictive markers for histological progression or lack of response, and evaluate new drugs or treatments.

Abstract
BACKGROUND Localized low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma can regress after Helicobacter pylori eradication, but IgV(H) gene monoclonality may persist. We studied the long-term histological and molecular follow-up of 24 patients and the possible association of t(11;18) with the persistent monoclonality. PATIENTS AND METHODS From January 1994, 24 untreated patients with stage I low-grade gastric MALT lymphoma associated with H. pylori were prospectively studied. They all received eradication treatment and were sequentially followed-up with endoscopies for histological and molecular studies. Rearrangement of the IgV(H) gene was studied by PCR analysis. MALT1 locus alterations were studied by FISH. RESULTS Twenty-two of the 24 patients (91%) achieved disappearance of the lymphoma. Eighteen (82%) of the 22 histologically cured patients and 16 of the 19 (84%) with long follow-up had monoclonality. Three patterns of development of IgV(H) gene rearrangements were observed: four patients (21%) had polyclonal rearrangements; eight (58%) had maintained/intermittent monoclonality and four (21%) had occasional monoclonality, mostly after H. pylori reinfection. Only one patient (6%) with persistent monoclonality relapsed. The remaining 18 patients maintained the remission, despite the persistent monoclonality in 15, for a median of 66 months (range 20-113). t(11;18) was not found in any of the patients with persistent monoclonality. Time and the number of endoscopies performed were not related with the occurrence of monoclonality. CONCLUSIONS In stage I low-grade gastric MALT lymphoma eradication of H. pylori achieves prolonged histological remission in 90% of patients, but molecular remission is not accomplished in most cases. Molecular disease persists for years, but is not associated with t(11;18).

Abstract
BACKGROUND Recent data suggest that chemotherapy with the cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) regimen is a highly effective treatment for localised primary gastric lymphoma of diffuse large B-cell histology (DLBCL). We have reported that the large majority of patients achieve complete remission (CR) following three cycles of treatment, and now provide an updated series with special emphasis on patients receiving only short-term chemotherapy. PATIENTS AND METHODS All patients with a histologically verified diagnosis of gastric DLBCL in stages EI and EII(1) undergoing chemotherapy with the CHOP regimen were evaluated. Data analysed included clinical stage, histology [presence of an additional mucosa-associated lymphoid tissue (MALT) component], evidence of Helicobacter pylori infection, H. pylori eradication, time to CR, survival and regular restaging (i.e. after three and six cycles, respectively). RESULTS A total of 37 patients with DLBCL of the stomach with localised disease were identified, five of whom also had a MALT component. Twenty-two patients presented with stage EI and 15 with stage EII(1) disease. All patients were given chemotherapy as sole management of their lymphoma; 36 patients received CHOP, while one patient was given CHOP along with rituximab. Thirty-two (86%) achieved a CR after a maximum of three cycles, while only four patients had to be given six cycles for CR. In total, nine of 37 patients (24%) discontinued therapy earlier than scheduled: one patient received one cycle, two received two, six received three and one patient received four cycles. Two of these patients stopped treatment due to toxicity, i.e. protracted thrombocytopenia or chemotherapy extravasation. One additional patient died after one cycle of treatment; autopsy disclosed no signs of remaining lymphoma. Three patients have died after a median follow-up of 39 months (including the one patient who discontinued therapy after one cycle of treatment), while the remaining 34 patients are alive without evidence of disease. Twenty-four out of 37 patients (65%) had also undergone H. pylori eradication (including six of nine patients receiving only short-term treatment). CONCLUSIONS DLBCL of the stomach appears to be a highly chemosensitive disease. Our data question the need for full-term CHOP treatment in patients achieving CR upon first follow-up. However, recent data suggest that additional H. pylori eradication might have contributed to the excellent results achieved in our series.

Abstract
BACKGROUND Most low grade gastric lymphomas arising from the mucosa associated lymphoid tissue (MALT) are related to Helicobacter pylori colonisation. Cases with disease limited to the stomach can be cured after H pylori eradication and remain in remission for years. In contrast, high grade lymphomas of the stomach, although also related to H pylori, do not usually respond to eradication treatment. CASE REPORT A 36 year old patient was referred from another hospital with a diagnosis of a low grade gastric MALT lymphoma associated with H pylori. The patient was in stage I and while waiting for the biopsies to be reviewed H pylori eradication therapy was given as the first step of treatment. Review of the biopsies showed a high grade immunoblastic lymphoma with areas of low grade gastric MALT lymphoma (high grade gastric MALT lymphoma or diffuse large B cell lymphoma with areas of MALT type lymphoma of the WHO classification). The patient received no further treatment but has been closely followed up for 32 months with sequential endoscopies to obtain biopsies for histological studies, H pylori cultures, and polymerase chain reaction analysis of the IgH gene. RESULTS After H pylori eradication the patient had a complete histological response that has been maintained for 32 months. Monoclonal IgH gene rearrangement persisted for 32 months. CONCLUSION The response of this patient indicates the possibility that some cases of high grade gastric MALT lymphoma (possibly patients in stage I with a superficial or limited disease) may still be responsive to H pylori antigenic drive and may be cured with eradication therapy. Prospective studies should be performed to identify patients with high grade gastric MALT lymphomas that may respond to eradication therapy and be spared of other more aggressive treatments.

Abstract
BACKGROUND AND OBJECTIVES Most cases of gastric low-grade mucosa-associated lymphoid tissue (MALT) lymphoma are associated with H. pylori. In localized disease (stage I), eradication of H. pylori can result in histologic regression of the lymphoma in 50% to 100% of the patients. Moreover, in half of the apparently cured patients a monoclonal rearrangement of the IgH gene can be demonstrated. However, data on the long-term outcome of the patients are scarce. We report the evolution of a series of patients followed-up since 1994 in order to evaluate the long-term outcome of the apparently cured lymphoma. DESIGN AND METHODS From January 1994 to July 2000, 19 consecutive patients with stage I gastric low grade MALT lymphoma were sequentially studied in our hospital. They had all been diagnosed by endoscopy and had had a complete staging (including CT-scan, contrast X-ray of the small bowel, bone marrow biopsies, immunophenotyping of bone marrow and peripheral blood and, in the later years, endoscopic ultrasonography). Diagnosis required established histologic criteria for low grade MALT lymphoma in the samples obtained by endoscopy. The investigation of H. pylori status included histologic search, serology and breath test urea-(13)C. Only patients in stage I disease associated with H. pylori were included in the study. Patients received standard triple therapy for eradication of H.pylori and after treatment were sequentially followed-up with endoscopies performed every 2-3 months in the first year, every 6 months in the second year and then yearly. Post-treatment biopsies were obtained by endoscopy for histologic studies, H. pylori cultures and molecular studies. The criteria of Wotherspoon et al. were used for the histological evaluation. Molecular studies were performed with a polymerase chain reaction analysis of the IgH gene using semi-nested procedures with consensus primers for the V(H) (Fr3A/Fr2A) and J(H) (LJH and VLJH) regions. RESULTS After the eradication treatment, 18 of the 19 patients (94.7%) achieved histologic regression of the MALT lymphoma that occurred after a mean of 4.6 months (range 2-19). In 11 of the 18 histologically cured patients (61%) a monoclonal rearrangement of the IgH gene was demonstrated. In 2 patients the monoclonality disappeared completely, but 9 of the 11 patients (82%) had either persistent (3 patients) or intermittently persistent (5 patients) monoclonality for as long as 64 months. None of the patients who achieved a histologic remission (either with or without monoclonality) relapsed after a mean follow-up of 37 months (range 2-78). Two patients were lost to follow-up and another patient died of a gastric carcinoma; the remaining 15 patients are still in histologic remission after a mean period of 43 months (range 5-78). Ten patients studied between 1994 and the end of 1996 are in remission after a mean of 59 months (range 33-78). INTERPRETATIONS AND CONCLUSIONS In most cases of gastric low-grade MALT lymphoma in stage I eradication of H. pylori can produce histologic regression of the lymphoma and this regression can be maintained for years. However, IgH gene monoclonality can be detected and persists in most cases. Although this persistent monoclonality seems to indicate the presence of a latent lymphoma population, over a period of 6 years it has not so far influenced the outcome. These findings indicate that in cases of localized gastric low-grade MALT lymphoma associated with H. pylori, the first step of treatment should be eradication of the H. pylori; however, a close and long follow-up is essential to determine the ultimate outcome of these patients and the possible significance of the persistent monoclonality.

Abstract
The effect of molecular factors in the outcome of Hodgkin's Disease (HD) is being currently studied. In a previous series of HD, including patients treated only with radiotherapy and patients treated with chemotherapy (with or without radiotherapy), we found that a high proliferation index had an adverse influence in overall survival (OS) and in the achievement of a complete remission (CR). Loss of Rb expression also had an adverse prognostic influence in achievement of CR. On the other hand LMP1-EBV expression had a favorable influence for OS. The expression of other molecular factors, p53, bcl2 and CD15 did not show prognostic influence. In the present paper we have studied the effect of these molecular variables in 110 patients, of the previous series who had been treated with chemotherapy. A retrospective study was performed in these 110 patients with HD treated with chemotherapy (ABVD or variants, 62%, or regimes not containing adriamycin, 38%) with or without adjutant radiotherapy, collected at the 11 centers belonging to the Spanish Collaborative Group for the Study of Hodgkin's Disease. The prognostic value of clinical variables and the expression of p53, bcl2, CD15, Rb, LMP 1-EBV and proliferative fraction demonstrated with sensitive immunohistochemical methods were studied. Cox's multivariate analysis was performed to assess their influence in failure-free survival (FFS) and OS. A multivariate logistic regression analysis was performed for studying the effect of the variables in the achievement of a CR. Of the clinical variables, only advanced stage (III/IV) had a significant independent adverse influence in FFS, in OS and in the achievement of CR and advanced age in OS. Of the molecular variables, LMP1-EBV had an independent and strong favorable influence in FFS, in OS and in the achievement of CR. Rb expression had a modest favorable influence in CR. The rest of the molecular variables had no independent influence on the outcome of the disease. In conclusion these results confirm the favorable prognostic value of LMP1-EBV expression in the subset of patients with HD treated with chemotherapy.

Abstract
A clinical evaluation of a new, purified, heat-treated equine rabies immunoglobulin (PHT-Erig), F(ab')2 preparation, was carried out in Thailand and in the Philippines-two countries where rabies is endemic. An initial prospective, randomised, controlled trial (Study 1), compared the safety and pharmacokinetics (serum concentrations of rabies antibodies) after administration either of PHT-Erig or of a commercially-available, equine rabies immune globulin (Erig PMC). A second trial (Study 2) simulated post-exposure rabies prophylaxis by using a reference cell culture vaccine, the purified Vero-cell rabies vaccine (PVRV), administered in association with either Erig PMC or PHT-Erig. In Study 1, 27 healthy, Thai adults received a 40 IU kg(-1) dose of either Erig PMC (n = 12) or PHT-Erig (n = 15) via the intramuscular (i.m.) route; half of the dose was injected into the deltoid area and the other half into the buttocks. Serum for rabies antibody determination and F(ab')2 concentration was collected at hours (H) 0, 6 and 12, and on day (D) 2, 3, 4, 6, 8, 10, 12 and 15. Both products were safe, with no serious adverse events, and in particular, no anaphylactic reactions or serum sickness was reported. A statistical comparison of the pharmacokinetic parameters did not demonstrate bioequivalence of the two products. Nonetheless, the relative bioavailability of 93% and the similar absorption rates suggest the pharmacokinetic profiles of Erig and PHT-Erig are similar. The antibody level in either group were low throughout the 15-day study period. The geometric mean titer (GMT) values ranged from group 0.027-0.117 IU ml(-1) in the Erig group and from 0.029 to 0.072 IU ml(-1) in the PHT-Erig. There was no significant difference between the evolution of GMT values for the two groups. In Study 2, 71 healthy volunteers received 40 IU kg(-1) via the intramuscular route of either Erig PMC (n = 36) or PHT-Erig (n = 35) on D0, in association with five doses of PVRV on D0, D3, D7, D14 and D28. The safety evaluation was performed during the 28-day follow-up and serum samples for anti-rabies antibody titration were collected on D0 (before injection) D3, D7, D14 and D28. No serious reactions were reported in either group. In particular, no immediate (anaphylactic type) or delayed (serum sickness) allergic reactions were observed. Over the 28-day follow-up period, GMT profiles of the two groups were statistically equivalent. On D14, 100% of the subjects had protective antibody titers (anti-rabies antibodies > or = 0.5 IU ml(-1), which is the WHO-recommended level of seroconversion), and Erig PMC and PHT-Erig were indistinguishable according to the clinical definition chosen. On D28, the GMT values were 33.2 IU ml(-1) (95% CI, 23.8-46.1 IU ml(-1)) in the Erig PMC/PVRV group and 31.4 IU ml(-1) (95% confidence interval, CI, 23.4-42.2 IU ml(-1)) in the PHT-Erig/PVRV group, showing evidence of adequate vaccine-induced antibody responses in both groups. The increased purity, the heat-treatment step introduced in the manufacturing process of PHT-Erig, and the good clinical results substantiate the use of this new generation, purified equine F(ab')2 preparation in the post-exposure prophylaxis of rabies.

Abstract
Previous studies have shown that in non-Hodgkin's lymphomas and others neoplasms, tumoral progression, treatment response, and outcome are related to the expression of different oncogenic and tumor suppressor proteins. This study aimed to determine the prognostic significance of the expression of p53, bcl2, retinoblastoma protein (Rb), Ki67, CD15, and latent membrane protein 1-Epstein-Barr Virus (LMP1-EBV) proteins in Hodgkin's disease. A retrospective study was performed on 140 patients collected at the 11 participating centers belonging to the Spanish Collaborative Group for the Study of Hodgkin's Disease. A highly sensitive immunohistochemical method with previous microwave-induced antigen retrieval technique was used for the demonstration of the above-mentioned proteins. A Cox's multivariate analysis was performed to evaluate the impact of the variables in the overall survival, together with a logistic regression model for the achievement of complete remission. Univariate statistical analysis confirmed the prognostic significance of the alredy known clinical parameters: stage, age over 60 years, and B symptoms. High proliferation index (Ki67) and loss of Rb expression were also found to be adverse prognostic factors influencing respectively lower overall survival and failure to achieve complete remission. Multivariate analysis confirmed the independent significance of these two parameters and additionally identifies LMP1-EBV expression as a favorable prognostic marker, in relation with overall survival. Histopathological type, p53, bcl2, and CD15 expression lack significant influence on the outcome of this series. The progression of the disease or the response to treatment in HD patients is the consequence of the interrelationship of different factors, among which LMP1 expression, loss of Rb, and high growth fraction seems to play a more relevant role.

Abstract
BACKGROUND Helicobacter pylori infection is associated with low-grade gastric MALT lymphoma, and available data support that the eradication of the H. pylori can cause histological regression of the lymphoma. PATIENTS AND METHODS Nine patients with low-grade gastric MALT lymphoma were treated with amoxicillin, metronidazole, and omeprazole for 14 days in a prospective study. Patients were followed up with sequential endoscopy, mapping gastric biopsies, and molecular studies with PCR amplification of the IgH gene in order to assess the response to H. pylori eradication and the evolution of the histological molecular responses. RESULTS H. pylori was eradicated in all patients and reinfections were not demonstrated. After H. pylori eradication treatment, the lymphoma regressed both endoscopically and histologically in eight of the nine patients (88.8%). In four of the eight histologically cured patients, no clonal band was detected by PCR; in the remaining four patients; PCR identified a clonal band, which disappeared in all patients after a mean of 12 +/- 4 months. No clonal band was detected by the PCR analysis in any of the eight patients with histological regression after a median of 7 +/- 6 months (range 1-20). The seven followed-up patients have a persistent clinical and histological remission after a median of 14 +/- 5 months. CONCLUSIONS (1) Low-grade gastric MALT lymphoma can be histologically cured with eradication therapy for H. pylori. (2) After histological regression, PCR amplification of the IgH gene can identify an eventually persisting clonal population. (3) Sequential histological and molecular studies are essential for the assessment of the evolution of the lymphoma. (4) The clonal population tends to disappear, but its disappearance may be delayed for months. (5) Patients with histological regression but with a persistent clonal band should not be treated unless the lymphoma can be histologically demonstrated. All these observations suggest that gastric lymphoma can be effectively cured, but the ultimate fate of these patients is unknown until long-term follow-up studies are available.

Abstract
Fludarabine is one of the most recent and promising therapeutic agents for chronic lymphocytic leukaemia. We describe a patient who developed tumour lysis syndrome after the first course of treatment with fludarabine and call attention to this uncommon but potentially lethal complication that has not been previously taken into account in this neoplasia. It should always be anticipated when patients are treated with new and effective drugs.

Abstract
Clinico-pathological features of 56 patients with primary gastric lymphoma were evaluated retrospectively. All cases were regraded according to a classification of Isaacson et al into high grade and low grade B-cell mucosa associated lymphoid tissue lymphoma. A third group of mixed grade was recognised in 11 patients with low grade who also had occasional areas of high grade. Low grade and mixed grade patients had a 100% actuarial survival at 156 months, which was significantly better (p < 0.01) than that of 52% for patients with high grade disease. Different treatment methods--surgery, chemotherapy, or a combination of both--did not significantly affect survival. Low grade tumours occurred mainly in men with a history of several years, and who presented with non-specific gastric symptoms without remarkable exploratory or laboratory findings: most patients were in stage IE-IIE and achieved remission and cure. High grade can have a shorter history, systemic symptoms, abnormal exploratory and laboratory findings, gastric tumour masses, stage IV disease, and a worse outcome. The only significant prognostic factors for survival were the type of lymphoma and stage IV disease. These findings support the Isaacson classification system which separates two extreme groups of gastric lymphomas with different morphology, behaviour, and outcome. The presence of limited areas of high grade in a specimen showing low grade does not change the outcome but suggests that primary gastric lymphoma forms a continuum between these extreme types.

Abstract
Hodgkin's disease was diagnosed in a 22-year-old HIV-seropositive man in 1986. Alternate MOPP/ABVD chemotherapy induced a clinical remission. He was asymptomatic until 3 years later when fever and peripheral and mediastinal lymphadenopathy appeared. Lymph node biopsy showed a large-cell anaplastic lymphoma and EBV genome was identified in the malignant cells, suggesting that transformation might had been induced by EBV. The present case affirms that in patients with HIV-related lymphomas who present enlarging lymphadenopathy after stable remission, the development of lymphomas of higher malignancy needs to be ruled out.

Abstract
A patient was admitted to our hospital, in the 34th week of her pregnancy, who presented a non-Hodgkin lymphoma. The delivery was induced in the 38th week and the newborn baby had no other anomalies than a single umbilical artery and a slight dilation of the cerebral ventricles which receded spontaneously. Peculiar characteristics, not previously described, were a peripheral T cell lymphoma with relapse after 5 years since its remission with chemotherapy.

Abstract
We describe 40 HIV-seropositive patients who developed visceral leishmaniasis. All the patients lived in areas endemic for visceral leishmaniasis and belonged to groups at risk for AIDS. Twenty-three patients (57.2%) had definitive AIDS before or after diagnosis of leishmaniasis and 77.5% were classified as belonging to CDC group IV. Fever was present in 95% patients and enlargement of the liver and/or spleen in 92.5%. Lymphopenia was found in 78.3%, depression of the absolute number of CD4 lymphocytes in 90% and depression of the CD4 to CD8 ratio in all evaluated cases but leishmania antibodies were found in only 35.2%. Parasites were demonstrated in the bone marrow or liver in every case. Thirty patients (75%) showed an initial good response to antimonial drugs, although the leishmaniasis followed a chronic or relapsing course in 17 (42.5%). HIV-related mortality was 40%. A significant correlation was found only between the relapsing course of the disease and mortality. In a multivariate linear regression model, the relapsing course was the only variable that influenced mortality. Visceral leishmaniasis is an opportunistic disease that should be suspected in HIV-infected patients. We suggest that it should be included in the CDC group IV C-1 and considered as a disease indicative of AIDS.

Abstract
In an area endemic for visceral leishmaniasis, 16 patients with human immunodeficiency virus (HIV) infection developed the disease. All belonged to populations at risk for AIDS (15 were intravenous drug abusers). Five patients fulfilled the criteria for full-blown AIDS, and two more fulfilled them after diagnosis of leishmaniasis. All presented with the classic manifestations of visceral leishmaniasis, but leishmania serology was negative in 15 patients (93%). Leishmania donovani amastigotes were identified in the bone marrow in all cases. Most patients responded initially to treatment with pentavalent antimonial drugs, but seven (43%) followed a chronic course, with multiple relapses in five, despite alternative treatments. Visceral leishmaniasis occurred in patients with different levels of depression of the CD4 to CD8 lymphocyte ratio. Mortality was 37% (six patients) and was independent of the chronic-relapsing course of the disease. In no case was leishmaniasis the primary cause of death. Our data establish that visceral leishmaniasis is an opportunistic infection in HIV-infected patients, and we suggest that in endemic areas it should be considered an indicator disease for the diagnosis of AIDS.

Abstract
The authors describe five white patients with peripheral T-cell lymphoma. Four patients were older than 65 years. All cases presented with a short clinical course and advanced stage at the time of diagnosis. Clinical manifestations included asthenia, weight loss, peripheral and abdominal lymphadenopathy. One case showed tonsillar involvement and subcutaneous lymph node enlargement; hepatomegaly was present in four cases, two of them with splenomegaly. Only one case presented peripheral lymphocytosis and antibodies to human T-leukemia virus. Although three cases were classified as diffuse mixed lymphomas and two as poorly differentiated lymphocytic lymphomas, there were some common characteristics: diffuse infiltration by different proportions of small lymphoid cells and large immunoblasts, some of them multinucleated and similar to Reed-Sternberg cells; accumulation of histiocytes, plasmacytosis, eosinophilia, venular proliferation and compartmentalization were also found. Bone marrow infiltration was observed in two patients. Results of monoclonal markers showed four cases to be OKT4+ and the other OKT8+. The morphologic and immunologic characteristics of these patients were typical and similar to those reported from other geographical areas.
