We have reviewed admission data, some diagnostic tests, treatment and outcome of 31 male homosexual patients infected with the human immunodeficiency virus with 37 consecutive episodes of presumptive Pneumocystis carinii pneumonia treated at the infectious disease unit, Auckland Hospital, between 1985 and 30 June 1988. The median age was 39 years. Eight episodes were proven Pneumocystis carinii pneumonia, 18 satisfied Centres for Disease Control criteria for presumptive Pneumocystis carinii pneumonia and 11 lacked one Centres for Disease Control criterion. Patients began intravenous or oral cotrimoxazole in 32 episodes, initially 20 mg/k/d of trimethoprim component, but since early 1988 10 mg/k/d. In nine episodes treatment was changed to intravenous pentamidine because of side effects or failure to respond while five received pentamidine as their only drug. Cotrimoxazole caused side effects in 20 of 32 episodes (rash in 11) and pentamidine in 10 of 14 (renal impairment in nine). Two patients died (ie, a 5% mortality for all 37 episodes or 8% for 26 proven and Centres for Disease Control presumptive episodes). Median hospital stay for survivors was 11 days. Fourteen other patients have subsequently died a median eight months after the initial episode. Pneumocystis carinii pneumonia is an important infection in patients infected with the human immunodeficiency virus.

A 55-year-old woman with common variable immunodeficiency and mild chronic obstructive lung disease received 3 units of plasma as immunoglobulin replacement therapy. During the administration of the final unit, her temperature rose 1 degree C, with no other observable symptoms. Fifteen minutes later she developed shortness of breath without nausea, vomiting, rash, or pruritus. In 30 min she lost consciousness, was breathless, and cyanotic. Resuscitative efforts failed. Autopsy failed to pinpoint a cause of death. There was no evidence of ABO or Rh incompatibility, bacterial contamination, or hemolysis. There were no neutrophil, platelet or IgA antibodies detectable in the patient or the 3 plasma donors. There were no lymphocytotoxic HLA antibodies in the patient or two of the plasma donors. The third donor had HLA-B35 lymphocytotoxic antibodies that did not agglutinate or aggregate neutrophils. The patient's HLA type was A2, A3; B35, B40. Lymphocytotoxic crossmatches using lymphocytes of the patient were positive with plasma from the third donor but negative with the other two. An eluate prepared from post-mortem lung parenchymal tissue was cytotoxic to 7 of 8 panel lymphocytes positive for the HLA-B35 antigen but not with cells lacking B35. The implicated plasma donor was healthy with a history of 6 pregnancies. This case report illustrates the potential hazard of transfusion of plasma containing HLA antibodies.

Lesions induced in rhesus monkeys by different isolates of simian immunodeficiency virus (SIV)/Delta were studied at necropsy. Four groups of monkeys were inoculated with SIV/Delta isolated from other experimentally infected rhesus monkeys, while one group was inoculated with SIV/Delta from an asymptomatic mangabey monkey. Three rhesus isolates and the mangabey isolate were virulent, killing 75-100% of infected monkeys. One rhesus isolate, which had been extensively passaged in vitro, was attenuated but was restored to virulence by single animal passage. Clinically, infected monkeys had lymphadenopathy, splenomegaly, diarrhea, and a rash. Most monkeys died of enteric disease. The following lesions were seen: weight loss, thymic atrophy, lymphoid atrophy, bone marrow hyperplasia, encephalitis, colitis, amyloidosis, hepatitis, glomerulosclerosis, and the presence of syncytial cells. One Rh Epstein-Barr virus (EBV)-related lymphoma occurred. Opportunistic agents were identified: cytomegalovirus, adenovirus, Cryptosporidia, and Pneumocystis. Shigella and Campylobacter often caused colitis.

A 29 year old white homosexual man presented with a two and a half week history of severe sore throat, fever, and extreme fatigue. His symptoms did not respond to antibiotics. He had mild bilateral conjunctivitis, a rash over his chest and back, and enlarged lymph nodes, but examination of the nervous system yielded normal results. He had low total white cell and platelet counts. The results of enzyme linked immunosorbent assay for human immunodeficiency virus (HIV) were equivocal when HIV IgM was detected in serum. Despite treatment with ampicillin his temperature remained high and he developed abnormal neurological signs, including a paraparesis and hyperreflexia of the arms. HIV was isolated from lymphocytes from blood and cerebrospinal fluid. Over the next six weeks the patient improved and was discharged. Two months later abnormal neurological signs persisted in his legs. Although various neurological syndromes associated with seroconversion to HIV have been described, this is probably the first report of a patient with myelopathy at the time of seroconversion.

A 21-year-old black man with sickle cell disease who has received blood transfusions for 11 years because of recurrent stroke has had a decline in numbers of circulating lymphocytes and T4 cells over the past four years. Two and a half years ago persistent generalized lymphadenopathy developed, associated with a positive test for human immunodeficiency virus (HIV) antibody. For the past seven months he has had a pruritic maculopapular rash, primarily on the extensor surfaces of the extremities. Multiple skin biopsies revealed only nonspecific perivascular infiltrates of mononuclear cells. This rash appears to be an unusual manifestation of HIV infection, and may be an indicator of impending AIDS.

A T-cell tropic retrovirus, simian immunodeficiency virus (SIV), has recently been isolated from immunodeficient rhesus monkeys. This virus has remarkable similarities to human immunodeficiency virus (HIV), the etiologic agent of acquired immunodeficiency syndrome. Subsequent studies of simian infection with SIV have shown it to be a relevant animal model for studying the pathogenesis of AIDS in man. In both HIV-infected humans and SIV-infected monkeys, a cutaneous maculopapular eruption has been described. To date, the pathogenesis and possible relationship of these exanthema to the evolution of systemic immunosuppression have remained obscure. In this study, the mononuclear cell infiltrates that characterize skin rashes of SIV-infected rhesus monkeys were found to be composed predominantly of cells with phenotypic characteristics of cytotoxic/suppressor (T8+) lymphocytes and natural killer cells. Many of these cells expressed membrane-bound interleukin-2 receptor molecules. Double labeling and immunoelectron microscopy revealed these cells in direct contact with degenerative Langerhans cells within the epidermis and dermis. These observations suggest that the cutaneous rash associated with SIV infection may be the consequence of target cell injury of Langerhans cells by effector cells with cytotoxic potential.

Immunoblastic lymphadenopathy (IBL)-like T-cell lymphoma is a distinct peripheral T-cell lymphoma, which closely resembles angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) and/or IBL, but is characterized by focal or sheet-like proliferation of immunoblasts and pale cells of T-cell nature. In this report, 36 patients with IBL-like T-cell lymphoma were analyzed. The disease is clinically characterized by generalized lymph node swelling, hepatosplenomegaly, fever, skin rash, polyclonal hypergammaglobulinemia, marked male predominance, predilection for the elderly, and poor prognosis. There was no association with human T-cell leukemia virus type I or human immunodeficiency virus. IBL-like T-cell lymphoma may be divided into two categories (CD4+ type and CD8+ type) by surface marker analysis. It can also be divided into three categories on the basis of the histologic findings of distribution of morphologically recognizable tumor cells: nine cases of "inconspicuous type," six cases of "patchy type," and 21 cases of "diffuse type." Two cases of "inconspicuous type" converted later to "diffuse type." DNA hybridization analyses in the ten recent cases revealed that three of four "inconspicuous types" and five of six "diffuse types" showed clonal rearrangement of T-cell receptor-beta chain gene without rearrangement of immunoglobulin heavy chain gene, providing strong evidence for clonal proliferation of T cells.

We report a patient who, 3 weeks after initiation of therapy, experienced a hypersensitivity reaction to phenytoin manifested as rash, lymphadenopathy, elevated serum transaminase levels, and subsequent panhypogammaglobulinemia with IgG, 180 mg/dl (control range 639 to 1349); IgA, 15 mg/dl (control range 70 to 312); and IgM, 0 mg/dl (control range 56 to 352). Repeated in vitro lymphocyte analysis documented normal T cell-mediated immunity including T cell surface markers (E rosettes), lymphocyte proliferation after mitogen stimulation, and T cell phenotypes (T4 or helper and T8 or suppressor cells). However, the patient had a paucity of circulating B-lymphocytes as assessed by the number of lymphocytes with surface membrane immunoglobulin (patient value of 0 compared to the control range 16 to 435 cells per microliter of blood) and by the number of lymphocytes bearing the B1 antigen (patient value of 13 compared to the control range 48 to 358 cells per microliter of blood). Hemolytic plaque assay revealed decreased immunoglobulin production (number of immunoglobulin-secreting cells per million circulating mononuclear cells) as compared to control subjects (patient unstimulated mean of 100 as compared to a control mean of 1753) and minimal enhancement on stimulation with pokeweed mitogen (patient stimulated mean of 250 as compared to control mean of 8946). Coculture experiments with the reverse hemolytic plaque assay revealed no evidence of suppression. No reversal of this patient's immunodeficiency has occurred 3 years after phenytoin withdrawal.

The clinical symptoms and signs were assessed in 20 consecutive patients developing infection with the human immunodeficiency virus (HIV). All were male homosexuals and all presented with a glandular-fever-like illness. Changes in laboratory values were compared with findings in 40 HIV negative male homosexual controls. In the 10 patients for whom date of exposure to the virus could be established the incubation period was 11-28 days (median 14). One or two days after the sudden onset of fever patients developed sore throat, lymphadenopathy, rash, lethargy, coated tongue, tonsillar hypertrophy, dry cough, headache, myalgia, conjunctivitis, vomiting, night sweats, nausea, diarrhoea, and palatal enanthema. Twelve patients had painful, shallow ulcers in the mouth or on the genitals or anus or as manifested by oesophageal symptoms; these ulcers may have been the site of entry of the virus. During the first week after the onset of symptoms mild leucopenia, thrombocytopenia, and increased numbers of banded neutrophils were detected (p less than 0.0005). The mean duration of acute illness was 12.7 days (range 5-44). All patients remained healthy during a mean follow up period of 2.5 years. Heightened awareness of the typical clinical picture in patients developing primary HIV infection will alert the physician at an early stage and so aid prompt diagnosis and help contain the epidemic spread of AIDS.

In the course of a prospective study of the prevalence and incidence of infection with the human immunodeficiency virus (HIV) and risk factors for the acquired immune deficiency syndrome among 961 homosexual men, 97 initially HIV antibody seronegative men reported a febrile period lasting at least three days. In 60 of these men serological evidence for an infection was found: influenza A or B virus (17 men), HIV (14), Epstein-Barr virus (seven), parainfluenza virus type I, 11 or Ill (five), hepatitis A virus (three), cytomegalovirus (three), adenovirus (two), respiratory syncytial virus (two), hepatitis B virus (one) and Toxoplasma gondii (one). Combined infections were found in five men. A total of 17 men seroconverted for HIV antibody. The clinical symptoms of acute HIV infection closely resembled those of influenza A or B infection. Skin rashes also occurred frequently in men with HIV infection. HIV antibody seroconversion gives rise to a number of different symptoms and primary HIV infection should be included in the differential diagnosis of prolonged febrile illness in those at risk of HIV infection.
