Eleven patients with rheumatoid arthritis that had been refractory to conventional drug therapy were treated with total lymphoid irradiation (TLI). Followup continued for 6 months in 9 patients, 12 months in 6 patients, and 24 months in 3 patients. At 6 and 12 months post-TLI, a significant improvement in clinical disease activity was demonstrated. Side effects noted during TLI included fatigue, nausea, diarrhea, and vomiting. One patient died of cardiorespiratory arrest, 2 patients died of kidney failure secondary to generalized amyloidosis, and 1 patient died of septic shock secondary to a multilocular septic arthritis. One patient experienced 2 episodes of septic arthritis; 2 patients manifested delayed wound healing. Immunologic assessments showed consistent lymphopenia in all patients. T lymphocyte subsets decreased after TLI, and showed a transient increase at 6 months post-TLI. The suppressed mitogen responsiveness, which was noted 2 months after irradiation, was found to increase almost to the pre-TLI levels at 12 months. The observed increase in morbidity and mortality after TLI is evidence that discourages the use of this therapeutic technique, at least in its present form.

The clinical signs, hematologic changes, serum and fecal virus titers, specific antibody production and the occurrence of histologic lesions were studied in 22 nine-week-old seronegative beagle dogs inoculated by the oral and intravenous route with canine parvovirus. Approximately 30% of the dogs had clinical signs of pyrexia, depression, vomiting, and diarrhea irrespective of the route of inoculation. Events in the dogs inoculated intravenously preceded those in dogs inoculated orally by approximately two days. Only one dog died. Lymphopenia was the most consistent hematologic change. Viremia always preceded the initiation of fecal virus shedding. Viral titers in the serum and feces were significantly greater in symptomatic dogs compared to asymptomatic dogs. Termination of the plasma viremia coincided with the onset of the humoral immune response, but viremia persisted one day longer in symptomatic dogs. The severity of lymphoid tissue and intestinal infection, assessed by tissue immunofluorescence and histology, was also greater in symptomatic dogs. The severity of intestinal disease was highly correlated with the magnitude and duration of viremia.

We herein report five new cases of severe combined immunodeficiency with hypereosinophilia, the so-called familial reticuloendotheliosis first described by Omenn. It is characterized by erythroderma, polyadenopathy, hepatosplenomegaly, severe and repeated infections, protracted diarrhoea with failure to thrive. There is marked eosinophilia as well as a profound immunodeficiency. The immunologic abnormalities consist of an increase in T cell number, a B cell lymphopenia and a complete lack of humoral and cellular immune responses to antigens. A deficiency of lymphocytes 5'-nucleotidase has been inconstantly found. Histologic findings are characteristic, consisting of severe T and B lymphocyte depletion in lymphoid organs with infiltration by histiocytes and, to a lesser extent, eosinophils. The outcome was uniformly fatal within the first year of life. Treatment by a combination of parenteral nutrition, steroids and epipodophyllotoxin was effective in obtaining the complete remission of clinical manifestations due to the histiocytic and eosinophilic infiltration in two patients. However, the treatment failed to correct the immunologic defect. These results indicate that the histiocytic infiltration is possibly not responsible for the immunologic detect observed in this condition.

Calves held in isolation showed a progressive decline in maternally derived antibody titres to bovine parvovirus but low concentrations of inhibitors resistant to heat and kaolin treatment persisted as the animals matured. These inhibitors had both haemagglutination inhibition and plaque neutralising activity and were considered to be of non-specific origin. Following oral challenge with bovine parvovirus, calves developed mild to moderate diarrhoea, with lymphopenia and viraemia. Sequential virological and immunofluorescent studies showed that the virus initially infected tonsils and intestinal tract, subsequently spreading to systemic lymphoid tissues. Histological and scanning electron microscopic examinations revealed moderate small intestinal villus atrophy and fusion due to crypt damage, together with lymphoid necrosis predominantly associated with the intestinal tract and thymus. Although the disease was not very severe, this may have been because the low parasite burden in the animals reduced mitotic activity in susceptible tissues.

An epidemic of nonbacterial gastroenteritis affected nearly 100 students at a college campus in Jefferson County, Alabama. The outbreak closely resembled food poisoning, since there was a rapid occurrence of multiple cases within a short period. Vomiting occurred in 79% and diarrhea in 64%; fever was uncommon. We found a significant association between the illness and the eating of lettuce at a meal one day before the outbreak began. Paired serologic specimens showed evidence of Norwalk virus infection. Twenty acutely ill students had leukocytosis (mean WBC 12,780/cu mm) and lymphopenia--a pattern that may be characteristic of Norwalk virus gastroenteritis. Outbreaks of Norwalk virus infection as well as other nonbacterial gastroenteritis may closely mimic epidemics caused by more familiar foodborne pathogens such as staphylococci.

One hundred fifty-eight hemophilia A, B, and von Willebrand disease (VWD) patients treated with clotting factor concentrates from a single manufacturer were tested for antibody to the human T-lymphotropic virus type III (HTLV-III). Antibody was detected in 63% and 40% of those with severe hemophilia A and B, respectively, 12% and 0% of those with mild hemophilia A and B, and two patients with recessive VWD. Forty-two antibody-positive and 20 antibody-negative patients were studied for clinical and laboratory features of infection. Eleven seropositive patients had clinical signs of infection including Pneumocystis carinii pneumonia, lymphadenopathy, splenomegaly or diarrhea; however, only one patient had developed acquired immune deficiency syndrome (AIDS), and only two had significant impairment of their performance status. Thirty-one patients remained totally asymptomatic. Eight patients had a history suggestive of acute HTLV-III infection. Thrombocytopenia was observed in 18% of seropositive patients, lymphopenia in 60%, depressed T-helper cells in 43%, reduced T-helper:T-suppressor ratios (TH:TS) in 33%, and elevated platelet-bound immunoglobulin in 53%. The antibody-negative group had normal T-helper cell levels (except one patient) and TH:TS ratios, and normal platelet immunoglobulin levels. Both groups demonstrated a significant elevation of immunoglobulin levels and a high prevalence of antinuclear factor and antismooth muscle antibodies. The mean level of IgG was significantly higher in the antibody-positive group. This study confirms the correlation between HTLV-III infection and reduced T-helper cells in hemophiliacs but demonstrates a low incidence of clinical symptomatology. There was evidence of polyclonal B-cell hyperactivity in the antibody-negative group as well as the seropositive group.

We report four cases of Omenn's syndrome (OS), an autosomal recessive disease characterized by early erythrodermia, protracted diarrhea, severe infections, lymphadenopathy, hepatosplenomegaly, failure to thrive, and leukocytosis with marked eosinophilia. The immunological investigations revealed B lymphopenia with increased levels of serum IgE and marked depression of T-cell activation, not restored by the addition of exogenous interleukin 2 (IL-2). IL-2 and interferon-gamma (IFN-gamma) production in vitro were very low or absent. One patient was treated with HLA-identical bone marrow transplant with a complete remission of the clinical picture and the immunological defect. The infant died of graft versus host disease 4 months after the graft. For the remaining three infants the outcome was also fatal within the first year of life. In conclusion, OS should be considered a severe combined immunodeficiency disease with peculiar clinical, immunological, and histological findings.

Sixteen patients with metastatic melanoma or metastatic renal cell carcinoma were treated with six weekly 24-hour infusions of recombinant interleukin-2. At least three patients were treated at each dose, beginning at 3.0 mU/m2 for 24 hours each week for 6 weeks. Subsequent patients were treated at 4.5, 6.0, 8.0, and 10.0 mU/m2 for 24 hours. The incidence of diarrhea, rigors, rash, edema, and symptomatic hypotension was positively correlated with dose level. Symptomatic hypotension was dose limiting at the 10-mU/m2 level. Fever, nausea, and vomiting were seen at each dose level and could not be correlated with dose level. Lymphopenia and eosinophilia were observed at the completion of each 24-hour infusion, and an increase in peripheral blood absolute lymphocytes and eosinophils was observed over the 6-week treatment period. No thrombocytopenia was observed. No change in delayed-type hypersensitivity (type IV) as determined by skin testing could be demonstrated at any dose level. Natural killer cell cytotoxicity of peripheral blood lymphocytes increased over the treatment period, but the increase was unrelated to dose level in the range studied. One minor response was documented in a patient with renal cell carcinoma.

Persistent generalized lymphadenopathy during HIV infection is now a well classified syndrome featuring multiple chronic lymph node enlargement frequently associated with further symptoms (diarrhea, nocturnal sweating, loss of weight, fever): it is invariably accompanied by serious alterations of the cell-mediated immunity including lymphopenia, reduced number of helper lymphocytes in circulation, inversion of the helper/suppressor ratio, lower proliferative response in vitro and deficient delayed skin sensitivity tests. Minor opportunistic infections are also more frequent, the most widespread being chronic oral candidiasis. Whenever several of these signs are associated in a single patient, especially if the immunitary deficit is severe, an immunomodulating treatment is indicated to improve the lymphocyte functionality and finally to modify any evolutive tendency. The Authors give the preliminary results of a pilot study carried out on 12 patients with LAS/ARC treated with Thymopentin at a dosage of 50 mg by intra muscular injection on alternate days for cycles of 30 days. Compared with 14 untreated patients, the subjects receiving therapy showed a more stable immunological picture, and improvement in subjective symptoms and a better therapeutic response to minor opportunistic infections.

Despite the recognition of Mycobacterium avium complex (MAC) infection as a common complication of AIDS, the specific clinical features, significance, and need for treatment have been difficult to assess. We reviewed the clinical records and autopsy material of 68 patients dying with AIDS, 32 (47 percent) of whom had MAC isolated from autopsy tissue. All had postmortem evidence of systemic infection. Eleven (34 percent) had MAC isolated from lung tissue. Little, if any, local tissue inflammation and destruction were associated with MAC infection. Patients with autopsy evidence of MAC infection had a longer time interval from diagnosis of AIDS to death. The infection was detected antemortem in 14 (44 percent), blood culture being the most sensitive means (86 percent yield). Although recurrent fever was noted among both MAC infected and uninfected patients, weight loss greater than 20 lb, weakness, anorexia, abdominal pain, and diarrhea were more frequent among infected patients. Severe anemia, thrombocytopenia, lymphopenia, and reduced mean CD-4 percentages and CD-4/CD-8 ratios were associated with MAC infection. Of eight patients who had MAC cultured antemortem and received multidrug antituberculosis therapy, none responded clinically, and all but one had MAC isolated at autopsy. Because MAC is associated with significant discomfort and disability, development of more effective treatment regimens could be beneficial for some affected AIDS patients.
