Non-Hodgkin's lymphomas (NHL) are part of the spectrum of disease associated with HIV infection. However, there are only occasional reports of NHL of T-cell origin in HIV-infected patients. A previously asymptomatic HIV-infected man, who was seronegative for human T-lymphotropic virus type I antibodies, developed a high-grade peripheral T-cell lymphoma of anaplastic large-cell type which was Ki-1 + (CD30 +), HLA-DR+, epithelial membrane antigen +, CD25 +, CD71 +, CD2 + and CD5 +. Pan-B markers CD19 and CD22 and histiocytic marker CD68 were negative. At diagnosis the patient had 0.3 x 10(9)/l T-helper lymphocytes. The response to chemotherapy was dramatic and the patient is alive and disease-free 18 months after treatment. A review of previously described peripheral T-cell lymphomas in HIV-positive individuals is performed, and we conclude that the spectrum of neoplasms in such cases is probably broader than originally thought.

A 50 year old patient with non-diagnosed HIV-infection at onset of his illness developed impairment of vision and temporary double vision combined with severe hemianopsia. With normal fundus and suspicious Herpes simplex iritis therapy with Acyclovir was started. Primarily the patient showed a good response to the therapy and loss of vision could be prevented. After 4 weeks CMV-retinitis developed. In spite of Gancyclovir therapy manifestation of total loss of vision after 6 weeks. Autopsy demonstrated signs of simultaneous a CMV-infection of the retina and a herpes simplex-infection of the optic nerve combined with a Non-Hodgkin-Lymphoma of the optic tract.

Cancer has been closely associated with human immunodeficiency virus (HIV) infection but this is less frequent in children. Non-Hodgkin's lymphomas represent the most frequently reported single tumor. The authors report seven cases of malignant tumors resulting from the analysis of all (n = 1321) children enrolled in the Italian Register for HIV Infection in Children. Tumors were distributed as follows: non-Hodgkin's B-cell lymphoma (four cases); and Kaposi's sarcoma, hepatoblastoma, acute B-cell lymphoblastic leukemia (one case each). Hepatoblastoma had never been previously reported in HIV-infected children. Also in the current series, non-Hodgkin's B-cell lymphoma is the most frequent single tumor. Five of the seven cancers belonged to the B-cell line. All but one of the seven children have died. Specific chemotherapy was provided in three cases, with some clinical improvement. The treatment of malignancies in HIV-infected children is hampered by increased risk of opportunistic infections often fatal even in children with apparent remission from the tumor.

All 51 cases of HIV-related malignant lymphoma in Denmark diagnosed from 1983 to 1989 were reviewed. There were 12 Burkitt-type lymphomas, 30 immunoblast-rich lymphomas and 9 other lymphomas. Patients with immunoblast-rich lymphomas had significantly lower CD4 cell counts (median 60 vs. 188 x 10(6)/l, P less than 0.05), and more often a history of previous AIDS-defining illnesses (50% vs. 0%, P less than 0.005), compared with patients with Burkitt-type lymphomas. Epstein-Barr virus (EBV) DNA was demonstrated in 14 of 19 immunoblast-rich tumours, and in 2 of 7 Burkitt-type lymphomas (P = 0.10). Compared with EBV DNA-negative tumours EBV DNA-positive tumours were associated with lower CD4 cell counts (median 39 vs. 188 x 10(6)/l, P = 0.01). It is concluded that two main types of HIV-related malignant lymphoma exist. One is associated with severe immunosuppression, is often of immunoblast-rich morphology, and may be linked to EBV, whereas the other may occur in the absence of immunosuppression, is often of Burkitt-type morphology, and is probably not linked to EBV. In addition to these two main types, other non-Hodgkin lymphomas and Hodgkin's disease do occur.

Six instances of lymphoma occurring in homosexual male patients among 140 HIV-positive subjects attended at our Department of Otolaryngology were evaluated for clinical features, histopathologic features and Epstein-Barr virus (EBV) DNA. The histology of the patients was consistent with a Hodgkin's lymphoma, centroblastic lymphoma and four lymphoblastic lymphoma. High malignancy and nodal localization were characteristic of four non-Hodgkin's lymphoma, which carries a poor prognosis. The DNA in situ hybridization studies demonstrated the presence of EBV DNA sequences in the four lymphoblastic lymphoma.

A case is described of an HIV+ man who was successfully treated for Hodgkin's lymphoma, but who later developed non-Hodgkin's lymphoma 3 years later when his immune system became suppressed. The patient was 22 years old when he presented with fever, asthenia, weight loss, and cervical lymphadenopathy. With Hodgkin's lymphoma he also had positive serology for HIV and hepatitis B. He was treated with alternate courses of MOPP and ABVD chemotherapy. In 1990 he again appeared with high fever, progressive cervical, axillary and inguinal lymphadenopathy, with hilar and mediastinal lymph node enlargement on x-ray. CD4 lymphocytes were 577/cubic mm, and the CD4/CD8 ratio was 0.57 (normal 1.8). His cervical lymph node biopsy was classified as non-B non-T large-cell anaplastic lymphoma which was EBV-positive. A Western Blot was positive for small amounts of p24 and p18 antigens. The man was treated with MACOP-B chemotherapy, with some results, but died of sepsis 6 weeks later. The relationships between Hodgkins and non-Hodgkin's lymphoma, the timing of the neoplasm in the course of HIV infection, and the possible re-activation of hepatitis virus were discussed.

Non-Hodgkin lymphoma is associated with HIV infection. We investigated the epidemiology and aetiology of AIDS-related non-Hodgkin lymphoma by analysing data from cases reported to the Centers for Disease Control, Atlanta, USA, up to June 30, 1989. During this period 97,258 AIDS cases were reported, of whom 2824 (2.9%) had non-Hodgkin lymphoma. The condition was about 60 times more common in AIDS patients than in the general US population. 1686 cases were immunoblastic lymphoma, 548 primary lymphoma of the brain, and 590 Burkitt's lymphoma, a condition which is not normally associated with immunosuppression. The proportion of AIDS patients with immunoblastic lymphoma increased from 0% in those under 1 year old to 3.5% in those aged 50 or more. Primary lymphoma of the brain was constant at 0.6% for all ages. The frequency of Burkitt's lymphoma increased from zero in infants to a peak at 10-19 years of age (1.8%). Each type of lymphoma was twice as common in whites as in blacks and in men as in women. Lymphoma was most common in patients with haemophilia or clotting disorders and least common in those born in the Caribbean or Africa who had acquired HIV by heterosexual contact. Epidemiological data suggested that whilst infectious agents (eg, Epstein-Barr virus) may be associated with development of non-Hodgkin lymphomas in AIDS patients there was probably no single cause for all the types of lymphoma. Perhaps the most puzzling question is why Burkitt's lymphoma is commonly associated with HIV infection but not with other types of immunosuppression.

Four out of eleven patients--none of them HIV positive--who received treatment for non-Hodgkin lymphoma by the MACOP-B protocol between June 1989 and February 1990 were taken ill during or shortly after the conclusion of the course with fulminant pneumonia necessitating artificial ventilation. In three cases Pneumocystis carinii was identified as the pathogen, and in one patient the diagnosis of pneumocystosis seemed probable. The mean cumulative doses given before the outbreak of pneumonia were as follows: cyclophosphamide 2753 +/- 1161 mg, methotrexate 1590 +/- 667 mg, bleomycin 36 +/- 16.8 mg and prednisone 4378 +/- 1734 mg. The mean haemoglobin concentration was 10.7 +/- 0.5 g/dl, leucocyte count 5250 +/- 2100/microliters, lymphocyte count 1300 +/- 300/microliters and lactate dehydrogenase 227 +/- 34 U/l. The cumulative doses and laboratory findings in the seven patients not affected by pneumocytosis were not significantly different. The patients with pneumonia were supported by mechanical ventilation for 6-26 days and treated with large doses of corticosteroids and co-trimoxazole. One patient died after 17 days' ventilation. Three patients were successfully weaned from the ventilator. Chemotherapy protocols such as MACOP-B predispose to acute Pneumocystis pneumonia. The risk of infection is independent of the cumulative doses of the drugs employed. For this reason, prophylaxis with co-trimoxazole is normally mandatory.

B cell subpopulations, as defined by double-labelling techniques with CD5 and CD19 monoclonal antibodies (MoAbs), were serially studied in 335 HIV-1 seropositive patients. At the time of the first consultation, no important modifications in either CD5+ or CD5- subpopulations were observed, whatever the stage of the disease. However, in 18 out of the 335 patients (5.37%), a sharp increase in B cells exceeding 20% and 300/mm3 was observed. This increase in B cells was mainly accounted for CD5-CD19+ B cell subpopulations and was associated with: (i) evolution of the disease, since only four patients presented it at their first consultation (one lymphadenopathy-associated syndrome (LAS) and three AIDS); (ii) advanced stages of disease since, at the time of B cell augmentation, two patients were staged as LAS, four as ARC and 12 as AIDS; (iii) a high incidence of non-Hodgkin's lymphomas (NHL) since three out of the 18 patients presented a histologically confirmed NHL and three others a clinical pattern compatible with this diagnosis. However, in three patients with B hyperlymphocytosis, polymerase chain reaction (PCR) studies of immunoglobulin gene rearrangement revealed the existence of a polyclonal expansion of B cells. These results justify inclusion of a pan-B cell marker in routine phenotypic studies of HIV-infected individuals, as well as the search for NHL among patients presenting this abnormality.

In a random HIV-seropositive population, malignant lymphomas were diagnosed in 31 patients, of whom 24 (77%) had non-Hodgkin lymphoma (NHL) and 7 (23%) Hodgkin lymphoma (HL). The prevalence of NHL among AIDS patients was 8% (23/279 cases), with a prevalence of 17% among autopsied patients (16/96 cases). No patient with HL had AIDS at the time of diagnosis. In 7 of 23 AIDS patients with NHL (30%) the diagnosis was made only post mortem; among these were all 5 patients with primary CNS NHL. Median survival from the time of diagnosis was 1 month for patients with NHL and 3 months for those with HL. In individual patients, survival for several years may be possible with chemotherapy. Certain patients with NHL appear to benefit from intensive chemotherapy with a combination of methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (MACOPB protocol). Appropriate, therapeutic strategies taking into account the patients' individual conditions, including the overall prognosis, urgently requires development. Metastatic CNS involvement, which was the primary cause of death in 5 of 11 patients with NHL (45%) receiving chemotherapy, represents a serious limitation to successful treatment.
