We report four cases of varicella-zoster pancreatitis in immunocompromised hosts. All 4 patients presented a severe immunodeficiency because of chronic lymphoproliferative disorders (mainly lymphoma and Hodgkin disease) and long-term immunosuppressive therapy. Varicella zoster pancreatitis is a very unusual presentation of varicella-zoster infection. Few cases of pancreatitis occurring after bone marrow transplantation have been reported. All 4 patients presented with acute epigastric pain associated with transient elevation of serum amylase. The vesicular rash followed the presenting symptoms of severe abdominal pain by 8 days. This clinical presentation, occurring in immunocompromised patients, defines a set of symptoms which should lead the physician to suspect varicella-zoster pancreatitis, even in the initial absence of the characteristic skin vesicular eruption. Early institution of antiviral therapy seems mandatory.

Infections of the central nervous system by Herpes simplex viruses (Herpes simplex type 1 and Herpes simplex type 2) are uncommon in acquired immune deficiency syndrome and are often clinically and pathologically atypical. We have collected 11 cases of herpes simplex encephalomyelitis in AIDS patients reported in the literature. Only 3 of these cases presented with a typical, necrotizing, limbic encephalitis. Other clinicopathological patterns included ventriculitis, rhombencephalitis and myelitis. Ventriculitis and rhombencephalitis were usually due to infection by HSV-1, whereas myelitis was mostly due to HSV-2 infection. Distinction between the 2 types of virus is often difficult by immunohistochemistry due to frequent cross reactivity and usually requires tissue culture, in situ hybridization, or polymerase chain reaction. Association of HSV encephalomyelitis with productive infection of the central nervous system by the human immunodeficiency virus was only found in one case. In contrast, co-infection with cytomegalovirus was found in 9 of the 11 cases. One case also had had varicella zoster virus vasculitis, and another case also had a cerebral malignant non Hodgkin's lymphoma in which Epstein Barr virus genome was identified. This supports the view that concomitant herpes-virus infections of the central nervous system is a characteristic feature of AIDS.

We reviewed 39 children < 15 years of age treated for Hodgkin's disease (HD) from 1973 to 1996. There were seven black, 12 white and 20 coloured children (of mixed ethnic origin). The M:F ratio was 2.9:1 and the median ages 147, 124 and 119 months in white, coloured and black children, respectively. Coloured and black children came mainly from a poor socio-economic background. Cervical lymphadenopathy was present in 74% and systemic symptoms in 51% of cases. Five per cent had clinical stage I, 41% stage II, 28% stage III and 26% stage IV disease. Two children underwent a staging splenectomy. The majority of white children presented with stages I and II and the majority of black and coloured children with stages III and IV HD. Nodular sclerosing (59%), mixed cellularity (40%) and lymphocyte-depleted (43%) were the most common histological subtypes in white, coloured and black children, respectively. Epidemiologically, white children fitted the criteria for HD type I and coloured and black children the criteria for HD type III. Nineteen children were treated with ChlVPP (chlorambucil, vinblastine, prednisone, procarbazine) and 20 with MOPP (mustine, Oncovin, procarbazine, prednisone) and/or ABVD (Adriamycin, bleomycin, vinblastine, DTIC) with involved field radiotherapy to bulky mediastinal disease. The projected 10-year survival after ChlVPP or MOPP/ABVD therapy was similar at 52%. In stages I and II, HD projected survival at 5 and 10 years was 85%, and in stages III and IV it was 82% at 5 and 48% at 10 years. The relapse rate was 47% in stage II, 45% in stage III and 44% in stage IV. Tuberculosis was suspected and treated in five children at the time of, and in seven children (three confirmed) subsequent to, the diagnosis of HD. Varicella developed in six and herpes zoster in five children. Five treatment-related deaths were due to septicaemia following splenectomy (two), marrow failure, corpulmonale and secondary leukaemia.

A UK population-based case-control study of Hodgkin's disease (HD) in young adults (16-24 years) included 118 cases and 237 controls matched on year of birth, gender and county of residence. The majority (103) of the cases were classified by Epstein-Barr virus (EBV) status (EBV present in Reed-Stenberg cells), with 19 being EBV-positive. Analyses using conditional logistic regression are presented of subject reports of prior infectious disease (infectious mononucleosis (IM), chicken pox, measles, mumps, pertussis and rubella). In these analyses HD cases are compared with matched controls, EBV-positive cases and EBV-negative cases are compared separately with their controls and formal tests of differences of association by EBV status are applied. A prior history of IM was positively associated with HD (odds ratio (OR) = 2.43, 95% confidence interval (CI) = 1.10-5.33) and with EBV-positive HD (OR = 9.16, 95% CI = 1.07-78.31) and the difference between EBV-positive and EBV-negative HD was statistically significant (P = 0.013). The remaining infectious illnesses (combined) were negatively associated with HD, EBV-positive HD and EBV-negative HD (in the total series, for > or =2 episodes compared with < or =1, OR = 0.45, 95% CI = 0.25-0.83). These results support previous evidence that early exposure to infection protects against HD and that IM increases subsequent risk; the comparisons of EBV-positive and EBV-negative HD are new and generate hypotheses for further study.

We report two patients who developed varicella zoster virus (VZV) ophthalmicus complicated by ipsilateral keratouveitis, and within 4 weeks developed acute retinal necrosis (ARN) in the contralateral eye. The ipsilateral retina was spared in each case. One patient had systemic lupus erythematosus (SLE) and the other Hodgkin's disease. Both patients were in remission at the time of presentation.

Highly active antiretroviral treatment (HAART), which has been available for most AIDS patients in France since 1996, has resulted in a dramatic improvement of the progression of the disease. From the survey of our series of 343 brains with acquired immunodeficiency syndrome (AIDS) from patients who died between 1985 and 2002, we found both quantitative and qualitative changes in the pattern of human immunodeficiency virus (HIV) neuropathology. Quantitatively, despite a dramatic decrease in the number of autopsies, brain involvement remained a major cause of death. There was an overall decrease in incidence of cerebral toxoplasmosis, cytomegalovirus encephalitis (CMVE), and HIV encephalitis (HIVE), for which successful treatment is available. This contrasted with the unchanged incidence of progressive multifocal leukoencephalopathy (PML) and malignant non-Hodgkin lymphomas (MNHL). However, when looking closer at the 3 last years, the incidence of diseases affecting patients with severe immunodepression (CMVE, PML, and MNHL) decreased between 2000 and 2002, whereas infections occurring in patients with milder immunodeficiency, toxoplasmosis, varicella-zoster encephalitis (VZVE), or herpes simplex virus encephalitis (HSVE) became more frequent. In addition, we found uncommon types of brain infection such as BK virus encephalitis or general paresis. Finally, we described new variants of HIVE: severe leukoencephalopathy with intense perivascular macrophage and lymphocyte infiltration, possibly due to an exaggerated response from a newly reconstituted immune system, and chronic "burnt out" forms of HIVE as VZVE, toxoplasmosis, or PML, possibly associated with prolonged survival, in which neither inflammation nor organisms could be detected. These findings are compared with those reported in other neuropathological studies from different developed countries.

Visceral disseminated varicella-zoster virus (VZV) infection occurred with acute graft-versus-host disease in a 33-year-old Japanese male with non-Hodgkin lymphoma who had undergone allogeneic stem cell transplantation from an HLA-identical sibling after reduced intensity conditioning chemotherapy. Although ganciclovir and acyclovir treatment was effective temporarily, the number of VZV-DNA copies in the blood remained at a high level, and the hepatitis was prolonged. The patient was treated with foscarnet, which led to improvement of the VZV viremia and the hepatic dysfunction. Foscarnet therapy should be considered for acyclovir-resistant VZV infection in the setting of allogeneic hematopoietic stem cell transplantation.

Introduction of Highly Active Antiretroviral Treatment (HAART) which is available for most AIDS patients in France since 1996, has resulted in a dramatic improvement of the disease course. From the survey of our autopsy series of (AIDS) cases and the review of other neuropathological studies from different developed countries, we found quantitative and qualitative changes in the pattern of human immunodeficiency virus (HIV) neuropathology. Quantitatively, there was a dramatic decrease in the number of autopsy cases but brain involvement remained a major cause of death in AIDS patients. There was an overall decrease of cerebral toxoplasmosis, cytomegalovirus encephalitis (CMVE) and HIV encephalitis (HIVE) for which successful treatment is available. This contrasted with the unchanged incidence of progressive multifocal leucoencephalopathy (PML) and primary malignant non Hodgkin brain lymphomas (PMBL). However, when looking closer at the last three years, the incidence of diseases affecting patients with severe immunodepression (CMVE, PML, PMBL) decreased in 2000-2002, whereas infections occurring in patients with milder immunodeficiency (toxoplasmosis, varicella-zoster encephalitis (VZVE) or herpes simplex virus encephalitis (HSVE) became more frequent. Qualitatively, there were uncommon types of brain infections, such as BK virus encephalitis or general paresis. Finally, new forms of HIVE were reported: severe leukoencephalopathy with intense perivascular macrophage and lymphocyte infiltration possibly due to an exaggerated response from a newly reconstituted immune system; and also chronic "burnt out" forms of HIVE as VZVE, toxoplasmosis, or PML in which no inflammation and no infectious agent could be detected, likely due to prolonged survival.

Immune reconstitution may be delayed after CD34-selected compared with unmanipulated autologous peripheral blood stem cell transplantation (PBSCT), resulting in a theoretically increased risk of infections. In a case-control matched study we compared the incidence of infection in 25 recipients of CD34-selected PBSC (CD34 group) and 75 recipients of unmanipulated PBSC (PBSC group) transplants. The population included 52 males and 48 females suffering from non-Hodgkin's lymphoma (n = 32), Hodgkin's disease (n = 8), multiple myeloma (n = 40) or breast cancer (n = 20). Neutrophil engraftment was comparable in the two groups. The actuarial incidence of infection was similar in the two groups (56% vs. 49% at day 30, and 70% vs. 64% at 1 yr respectively). The proportion of patients with 1, 2 or 3 infections, the number of infectious event per patient (1.32 vs. 1.04; NS), the number of infections before day 15 or 30, between days 31 and 100 or after day 100, the risk of varicella-zoster virus or cytomegalovirus infection or disease, or the use of antibiotic or antifungal therapy, were not increased in the CD34 compared with the PBSC group. The main agents responsible for infection were bacteria, particularly gram-positive cocci, in both groups. Bacteremia accounted for 33% of all infectious events in the CD34 group vs. 16% in the PBSC group (P < 0.05). Fungal infections were rare. In conclusion, our results do not support the notion that CD34-selection of the graft is associated with an increased rate of infection after autologous PBSC transplantation. The role of extended infection prophylaxis should be evaluated.

Treatment of B-cell non-Hodgkin's lymphomas (NHL) with either Rituximab alone or in combination with cytotoxic chemotherapy has been effective without major side effects. Thus, Rituximab maintenance therapy after autologous peripheral blood stem cell transplantation (PBSCT) might represent an improvement in NHL therapy. We therefore retrospectively analyzed the efficacy and side effects of monthly long-term Rituximab maintenance therapy after PBSCT in 27 patients with NHL. In median 10 infusions of Rituximab were given after PBSCT in time intervals of 1 month. Molecular monitoring of t(14;18) was performed using nested as well as quantitative real time polymerase chain reaction (RT-PCR) based on the LightCycler technology. Side effects according to common toxicity criteria (CTC) > II did mainly affect the hematopoietic system. In total, 10 patients (37%) suffered form grade III-IV hematotoxicity. Except for two patients with cutaneous Varicella-Zoster infection no serious infectious complications (CTC grade III/IV) occurred. No patient died because of treatment-related causes. This adverse event data compared favorably to the published data. Three patients had t(14;18) nested RT-PCR positive results before Rituximab therapy and converted to negativity after Rituximab therapy. We conclude that a prolonged Rituximab maintenance therapy after PBSCT with monthly administration is reliable and safe.
