The clinical features of our cases demonstrated some of the already known characteristics of the variable spectrum of HIV infection. DA are the most important risk category in Italy. 10% of the ARC cases evolved into AIDS during a 12-month follow-up, on average. The most frequent OI in our AIDS cases were PCP, C. albicans esophagitis and chronic mucocutaneous ulcers. An high percentage of neurologic involvement from HIV was observed, and malignancies were encountered in AIDS (3 KS and 1 undifferentiated B lymphoma) as well as in ARC (1 Hodgkin's lymphoma). Statistically, significant worsening of the immunologic situation is evident as the disease progresses from LAS to AIDS. Activated B lymphocytes represent most of the cells of the germinal center during the hyperplastic stage of lymphadenopathy. Reversal of the T4/T8 ratio appears early during the initial stage of lymphadenopathy and is due to a decrease of CD4 and a relative increase of CD8. Also, destruction of the follicular dendritic cells is an early feature which becomes more evident as the disease advances and the lymph node evolves toward progressive involution. Activated B-lymphocyte augmentation with polyclonal Ig secretion appears to be related to T-independent B stimulation by coinfection such as CMV, EBV and HBV. The increase of cytotoxic/suppressor lymphocytes seems to be partly related to the excessive activation of B lymphocytes and partially directed to the cells infected by HIV or coated with its proteins (6,7,8,9). The destruction of follicular dendritic cells has been interpreted not only as a killer effect of the virus but also as a result of the intervention of CTL sensitized to the cells containing the virus (10,11). Their destruction may contribute to the impaired recognition of soluble antigen which is one of the main features of the immune deficiency of HIV infection (9,13,16).

Pneumocystis carinii is observed in the bone marrow of two adults immuno-compromised; the initial diseases are on the one hand a Hodgkin's disease, on the other hand a malignant lymphoma for immunocytoma type, which necessitate heavy and invalidating treatments. A Pneumocystis carinii pneumonia with respiratory distress seems to have carrying away two patients death. Eventually pathogenic part of the parasite in the bone marrow localization.

We review the clinical features and histopathologic changes observed in 69 cases of lymphadenopathy in homosexual men. The most common pattern seen was that of florid reactive follicular hyperplasia (43 cases). A peculiar and distinctive lysis of the germinal centers, a phenomenon we have termed "follicle lysis," was noted in 25 cases. Eighteen of these lymph nodes also contained sinusal collections of "monocytoid" cells and neutrophils and six showed focal dermatopathic changes. Seven cases were characterized by a lymphocyte-depleted pattern with only occasional regressively transformed germinal centers. Nine patients were found to have involvement of their lymph nodes by Kaposi's sarcoma; malignant lymphomas were encountered in 10 patients (eight with Hodgkin's disease and two with non-Hodgkin's lymphomas). Polykaryocytes (multinucleated giant cells) were observed in germinal centers or interfollicular areas within the lymph nodes of four patients. Limited clinical follow-up was available but the lymphocyte-depleted group appeared to have a more aggressive clinical course (three patients in this group developed pneumocystis pneumonia, two had mycobacterial infections and one cutaneous Kaposi's sarcoma). The diverse nature of these findings and the potential for treatment of certain patients (i.e., those with malignant lymphomas and mycobacterial infections) underlines the importance of lymph node biopsy in all cases of unexplained lymphadenopathy in homosexuals and other individuals susceptible to the acquired immunodeficiency syndrome (AIDS). The histopathologic findings may also serve to identify a subgroup of these patients at increased risk to develop more severe AIDS-related complications.

Diffuse pulmonary infiltrates and acute respiratory compromise frequently occur in patients with cancer who are undergoing chemotherapy, and treatment remains controversial. We initiated a prospective randomized trial in 22 nonneutropenic patients to compare the efficacy of immediate open lung biopsy with that of empirical trimethoprim-sulfamethoxazole and erythromycin therapy with delayed open lung biopsy if no clinical improvement occurred after 4 days of therapy. Diagnoses included non-Hodgkin's lymphoma (15 patients), T-cell lymphoma (2), acute lymphoblastic leukemia (3), Hodgkin's disease (1), and breast cancer (1). The median age was 40 years, and fever (18) and tachypnea (13) were the most frequent signs. Median room air arterial oxygen tension in 18 hypoxic patients was 53 mm Hg; 19 patients had diffuse pulmonary infiltrates. Eight of the 10 patients randomized to empirical antibiotic therapy showed improvement after 4 days. The 2 patients whose condition did not improve and who underwent delayed open lung biopsy had Pneumocystis carinii pneumonia. One of them did show improvement, and the other died of respiratory failure. Time to clinical resolution in the 9 surviving patients was 14 days; 4 required prolonged ventilation (longer than 24 hours). Findings for the 12 patients randomized to immediate open lung biopsy were P. carinii pneumonia in 7 and nonspecific pneumonitis in 5; there were 3 deaths related to open lung biopsy. Time to resolution in the surviving patients was 13 days for those with P. carinii pneumonia and 5 days for those with nonspecific pneumonitis; 7 required prolonged ventilation.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty pulmonary infiltrates in 26 patients were investigated by bronchoalveolar lavage. Sixteen of the patients were on therapeutic immunosuppression for renal disease or transplant and 10 had leukaemia, lymphoma, or allied conditions. A rapid specific diagnosis was made in 21 (70%) episodes by cytological examination of the fluid and in 28 (93%) by a combination of cytology and microbiology. No complications from haemorrhage or pneumothorax ensued. Pneumonia due to Pneumocystis carinii was the most common diagnosis (27%), but opportunistic infections from cytomegalovirus, candida, aspergillus, zygomycetes, and acid fast bacilli were also identified by cytology. Two episodes were caused by occult pulmonary haemorrhage and five patients had malignant infiltration of the lung from leukaemia, myeloma, Hodgkin's disease, and lymphoplasmacytoid lymphoma. In two of these there was also evidence of infection. In seven cases with non-diagnostic cytology infections due to Staphylococcus aureus, Pseudomonas aeruginosa, pneumococcus, micrococcus, and Aspergillus fumigatus were identified on culture. In two patients (7%) no specific diagnosis was established by lavage: one had serological evidence of legionella infection and the second had P aeruginosa septicaemia. Twelve (75%) of the renal patients and six (60%) of those with leukaemia, lymphoma, and allied conditions recovered.

Thirty-six patients with advanced Hodgkin's disease who were treated primarily with MOPP were evaluated to determine the reasons for MOPP failure. Complete remission was achieved in 22 (61%) of the patients, and the predicted 5-year survival rate for all patients is 60%. Reasons for the failure of MOPP to cure patients in this series included: 1) Idiosyncratic drug reactions in 2 patients (6%). MOPP was discontinued after one cycle because of drug-related hepatitis or skin rash; 2) Resistant disease in 8 patients (22%). Primary treatment failure was significantly associated with the presence of B symptoms (p = .005) and age greater than 40 years (p = .02); 3) Death from complicating infection in 5 patients (14%). Four patients died without evidence of Hodgkin's disease while responding to MOPP from pneumocystis pneumonia, viral pneumonia, bacterial pneumonia, or bacterial septicemia. One patient died in complete remission from sudden, overwhelming sepsis; 4) Relapse from complete remission in 4 patients (11%). All patients who relapsed had deviations from the planned dose or timing of MOPP. Remission duration was shorter (p = .06) in patients with documented deviations in MOPP administration than in patients without such changes. It appears that new treatment approaches are needed for patients with B symptoms, and that failure to deliver MOPP on schedule in the planned dose increases the risk of relapse.

A 24-year-old female with Hodgkin's disease and Pneumocystis carinii pneumonia was tested with trimethoprim/sulphamethoxazole (TMP/SMX) tablets. Because treatment failure was feared owing to chronic emesis potentially resulting in incomplete drug absorption, the same TMP/SMX dose was administered by rectal suppositories after the 5th day of oral dosing. The relative fractions (rectal/oral) or the suppository dose absorbed for TMP and SMX were 3.0% and 19.5% respectively. When TMP/SMX treatment is required and the oral route is not practical, the investigational i.v. preparation should be obtained.

The presence of neutrophils, in the absence of necrosis, is uncommon in malignant lymphoma (ML). We identified a subgroup of Ki-1-positive anaplastic large cell ML (Ki-1 ALCL) in which neutrophils were a prominent component. Six of 20 cases of Ki-1 ALCL had a significant neutrophil infiltrate that varied from 5 to 10% to > 50% of cells per high power field. Neutrophils were not seen in 100 cases of other types of ML reviewed. Patients were first seen with skin lesions (four), localized lymphadenopathy (three), generalized lymphadenopathy (one), and localized extranodal disease (one). All had primary disease. Two patients had peripheral neutrophilia. Three of six patients had clinical stage IV disease. Four patients are currently in clinical remission; one died of recurrent disease; and one patient with acquired immunodeficiency syndrome (AIDS) died of Pneumocystis carinii pneumonia. Four cases demonstrated a T-cell phenotype, one of which arose in a patient with AIDS. Two had a B-cell phenotype. All cases were positive for CD30 (Ki-1). These observations expand the morphologic spectrum of Ki-1 ALCL to include a neutrophil-rich variant. We conclude that the presence of neutrophils is another morphologic feature shared by some cases of Ki-1 ALCL, lymphomatoid papulosis, and Hodgkin's disease, which suggests a possible pathogenetic link among them.

A case of Hodgkin's disease who developed Pneumocystis carinii pneumonia (PCP) is described. The diagnosis of P. carinii was confirmed on post-mortem lung biopsy. The rarity of its occurrence in our country is emphasised as is the need for high degree of suspicion and early institution of treatment.

In 1993 in Germany an estimated number of 50,000-70,000 individuals were infected with the human immunodeficiency virus (HIV), WHO estimations ranged up to 14 million HIV-positive individuals including 1 million children. AIDS-related diseases frequently occur in the lung. 65% of all AIDS-defining illnesses begin with life-threatening pulmonary infections. Most frequently HIV-positive patients present with Pneumocystis carinii pneumonia, followed by atypical mycobacteriosis, bacterial infections, Kaposi's sarcoma and non-Hodgkin lymphoma. The purpose of this article is to identify pulmonary HIV-associated diseases by focusing on radiological patterns and correlating them with clinical findings.
