Neoplastic disease arose in 29 of 200 patients infected with human T lymphotropic virus type III (HTLV-III) seen at a suburban hospital. Seventeen patients had Kaposi's sarcoma, one of whom also had colon carcinoma. Nine patients had lymphoproliferative disorders (seven lymphomas, one T suppressor cell chronic lymphocytic leukemia, and one multiple myeloma), including three with concomitant Kaposi's sarcoma and one with colon cancer. One other patient had colon cancer, one had a seminoma, and one had pancreatic cancer. Kaposi's sarcoma as a complication of AIDS occurred mainly in homosexuals (17 of 42 homosexuals, one of 17 drug abusers, one of five heterosexually promiscuous patients, and one of six patients who had previously received transfusions). The high-grade lymphomas did not show a predilection for any particular AIDS risk group. Three of four solid tumors arose in elderly AIDS patients. Twenty-five of 75 patients with CDC-defined AIDS had a neoplastic disorder (26 are still alive and may yet demonstrate malignancy). Few other diseases of man have been associated with as high an incidence of neoplastic transformation as occurs with HTLV-III infection.

Kaposi's sarcoma and B-cell lymphomas have been reported to develop in homosexual men with the acquired immunodeficiency syndrome (AIDS) or chronic lymphadenopathy syndrome (CLS). We treated what we believe is the first documented case of multiple myeloma complicating CLS in a 31-year-old male homosexual. This broadens the spectrum of B-cell neoplasms associated with AIDS and has implications for the pathogenesis of B-cell lymphomas and the evaluation of these high-risk patients.

Twenty-one (100%) Haitians and 42 (21.5%) of 192 native black Americans autopsied in a 33-month period at Jackson Memorial Hospital, Miami, were included in this review. All autopsied materials were examined. Among the Haitians autopsied, infectious diseases accounted for 11 (52%) of 21 deaths. Toxoplasma encephalitis was the leading cause of death (five cases). Other infectious causes of death included disseminated cryptococcosis (one), disseminated cytomegalovirus diseases (one), Pneumocystis carinii pneumonia (one), chronic active hepatitis B (two), and bacterial pneumonia (one). Malignant neoplasms were also found to be causes of death and these included a single cases of each of the following: adenocarcinoma of the lung, multiple myeloma, diffuse histiocytic lymphoma, hepatoma, and Kaposi's sarcoma. Deaths of the remaining cases were due to hypertensive cardiovascular diseases (two), rheumatic heart disease (one), glomerulonephritis (one), and intimal fibroplasia of coronary arteries (one). Seven Haitian cases fulfilled the Centers for Disease Control case definition for the acquired immune deficiency syndrome (AIDS). For comparison, autopsies of black Americans were chosen from conditions that would most likely predispose them to opportunistic infections. Among the autopsies on black Americans there were no cases of opportunistic infections or Kaposi's sarcoma that were considered to be consistent with the AIDS.

Transforming growth factor beta (TGF-beta) is a multifunctional peptide that controls proliferation, differentiation, and other functions in a variety of cell types. Transforming growth factor beta activities have been implicated in a variety of diseased states including arthritis, prostate cancer, and AIDS, and in the repair of tissue injury caused by trauma, burns, and surgery. We describe the development and characterization of novel murine monoclonal antibodies (MAbs) to the latency-associated peptide (LAP) of TGF-beta 1, and the subsequent development of an ELISA for the detection and quantitation of TGF-beta 1-LAP in buffer and serum matrices. Fusion of immune splenocytes with myeloma cells yielded 576 hybridomas, 110 of which were antibody secreting. Five were selected for extensive characterization. Clinically, the MAbs described here should be valuable for studying potentially abnormal production and/or function of the LAP, and its relationship to TGF-beta.

Adenosine deaminase (adenosine aminohydrolase, EC 3.5.4.4; ADA) activity is widely distributed in human tissues and is highest in lymphoid tissues. Two ADA isozymes are known as ADA1 and ADA2. Human tissue extracts contained ADA1 predominantly. Meanwhile, ADA2 was the main component of serum ADA. ADA activity was significantly elevated in the sera from patients with hepatic diseases, hematological malignancies and infectious diseases. Serum concentrations of ADA1 were high in patients with acute leukemias, chronic myeloid blast crisis leukemia and acute liver injury. Serum ADA2 levels were raised in patients with adult T-cell leukemia, multiple myeloma (B-J type), infectious mononucleosis, rubella, acquired immunodeficiency syndrome, chronic hepatic diseases and tuberculosis. It is supposed that ADA1 is derived mainly from injured tissues or cells while ADA2 comes from stimulated T-cells.

Rhinocerebral phycomycosis is an uncommon opportunistic infection with ubiquitous fungi of the class Phycomycetes, starting in the nose and extending to the paranasal sinuses and then intracranially. The condition is often characterized by poor prognosis because of occlusion of the internal carotid artery. This disease is commonly associated with predispositions such as uncontrolled diabetes mellitus, which is the most common, immunosuppressive states and metabolic bankruptcy including leukemia, lymphoma, myeloma, malnutrition, uremic or diarrheal acidosis, severe burns, anemia, carcinoma, radiotherapy, liver cirrhosis, hemochromatosis, tuberculosis, septicemia, long-term medication of steroid, antibiotics and antimetabolite, drug addiction, cytotoxic drug administration and AIDS. Cases with unknown predisposition, however, have been infrequently reported in the literature. The authors report a case of rhinocerebral phycomycosis in which concurrence of Candida species instead of the above-mentioned common predispositions was considered a potential predisposition. To our knowledge, only 1 report in which Candida species are referred to as a potential predisposition for this disease has been previously issued. A 85-year-old man was admitted to our hospital on March 2, 1994 because of generalized convulsion. He had received a total extirpation of an ascending colon cancer in July 1993. On admission, physical inspection showed no abnormalities and neurological examination revealed obtunded consciousness without other abnormalities. He had no diabetes mellitus. Hematological and blood chemistry values were normal except for CA19-9 of 45 U/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

It is well documented that despite global abnormalities of the immune system in AIDS and other immune deficiency diseases or in immunosuppressed patients, the incidence of only a few kinds of tumor increases, and that the degree of immunosuppression seems not to be a critical factor in the development of even these tumors. The fact that tumors do not develop in the majority of population during their lifetime, despite the ineffectiveness of the known immune system against the majority of tumors, can only be explained by hypothesizing that the living system has an additional defense mechanism against tumors. On the bases of literary data, it can be assumed that the effective agents of this defense mechanism are certain substances of the circulatory system. We proved this hypothesis by being able to select thirteen substances of the circulatory system from 71 compounds tested, using the synergistic tumor cell-killing effect as criteria. The mixture containing the thirteen substances (L-tryptophan, L-tyrosine, L-methionine, L(-)-malate, L-ascorbate, L-arginine, L-phenylalanine, L-histidine, 2-deoxy-D-ribose, d-biotin, pyridoxine, adenine and riboflavin) had a cytotoxic effect against Sp2/0-Ag14 mouse and K562, HEp-2, HeLa and Caco-2 human tumor cell lines in well-controlled conditions, but it was not cytotoxic against Vero normal cell line. The mixture of the above substances increased significantly the survival time of mice (T/C% 148.1) injected i.p. with Sp2/0-Ag14 mouse myeloma cells by killing more than 2 logs (99%) of the cells. Approximately the same 2 logs cell kill was found counting the Sp2/0-Ag14 cells in the ascitic fluid of control and treated animals after finishing treatment. The above mixture slowed down the growth of HeLa solid tumor significantly (T/C%, the least value 35.7). The weight loss of control and treated group during treatment did not differ significantly.

Expression of CD4 is not sufficient for cellular susceptibility to HIV-1 entry. The majority of nonprimate cells appear to lack a factor that plays an accessory role to CD4 during virus-cell fusion. We have previously reported CD4-dependent entry in rat myeloma Y3 cells, and here we show that Y3 and CD4-expressing mouse L929 cells fuse spontaneously to produce heterokaryons susceptible to entry by HIV-1. The results suggest that a putative accessory factor necessary for entry of HIV-1 into cells is expressed by the nonprimate Y3 cell line.

This prospective open trial evaluated the efficacy and tolerability of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) in patients with established neutropenia, considering as the main endpoint the clinical benefit to the patients regarding clearing of infection or resuming chemotherapy as initially planed. Adult patients (n = 28) with absolute neutrophil counts (ANC) < 10(9)/1 for 21 days were given a fixed dose (400 micrograms) of rhGM-CSF subcutaneously, for a total of 35 cycles. Causes of neutropenia were chemotherapy for acute leukaemia, lymphoma, myeloma and solid tumours, complications after bone marrow transplantation (BMT), and neutropenia associated with AIDS. Response (ANC to > 10(9)/l) occurred in 83% of rhGM-CSF cycles (29/35). Median time to response was 2.4 days (mean 6.7 days). Kinetics of response was dependent on diagnosis and treatment history. Fever abated with increasing ANC in 13/17 patients (76%) who entered the trial with hyperpyrexia. Treatment with rhGM-CSF allowed chemotherapy to be resumed on schedule in 7/9 relevant cycles. Toxicity was mild, leading to treatment interruption in only two cycles. In conclusion, rhGM-CSF was well tolerated and associated with a rise in ANC which appeared to result in immediate clinical benefit, including resolution of infection and resumption of scheduled chemotherapy.

The case notes of patients with blood cultures positive for enterobacteriaceae were examined retrospectively over a 6-month period in Parirenyatwa Hospital, Harare, Zimbabwe. Speciation was possible for Salmonella typhi and shigellae only. Nontyphoidal salmonellae were serotyped. Salmonella or shigella bacteremia was identified in 51 patients. There were 14 isolates of S. typhi, 32 isolates of nontyphoidal salmonellae, and 5 isolates of shigellae species. The case notes of 38 patients could be identified for review, and of these HIV serology was available for 15 seropositive and 15 seronegative patients. The male to female ratio was approximately 3:1 for both groups and the mean age was 29.7 +or- 21. Nontyphoidal bacteremias as compared with typhoid fever were strongly associated with HIV seropositivity [p 0.01]. 3 out of 8 HIV-negative patients with nontyphoidal bacteremia had another underlying immunosuppressive disease [2 had myeloma and 1 patient had cirrhosis with complicating hepatoma]. 2 patients with nontyphoidal bacteremia whose HIV status was unknown also had another immunosuppressing disease [acute myeloid leukemia and idiopathic pancytopenia]. 13 out of 15 HIV-positive patients showed other signs of HIV infection [oral candida, herpes zoster, persistent generalized lymphadenopathy]. 3 out of 11 patients [27%] with typhoid died, while 11 out of 27 patients [40.7%] with nontyphi bacteremia died. Most strains of S. typhimurium were included in serogroup B, which accounted for 37% of nontyphoidal isolates. Earlier studies identified invasive salmonellosis in patients with other AIDS defining diseases. In Nairobi clinical features of HIV infection were found in 64% of bacteremic HIV-positive patients, but only 28% of patients fulfilled the CDC clinical case definition for AIDS. A more recent study from Nairobi demonstrated that S. typhimurium bacteremia is a common cause of intercurrent infection in HIV-positive tuberculous patients.
