Immunologic abnormalities in patients with malignant lymphoproliferative diseases.

The B- and T-lymphocyte distribution was studied in 45 patients with malignant lymphoproliferative diseases. Eight patients with untreated Hodgkin's disease had normal mean percentages of complement receptor lymphocyte (CRL) cells and T-cells; however, the mean absolute number of T-cells was decreased. T-lymphocytes were also decreased in 3 patients with Hodgkin's disease treated 7-24 months previously. The number of T-lymphocytes increased markedly in all patients after treatment. Lymphocyte surface markers in non-Hodgkin's lymphoma showed distinctive patterns. Patients with leukemic reticuloendotheliosis or "hairy cell leukemia" characteristically had low percentages of CRL but normal or increased percentages of surface immunoglobulin-positive lymphocytes. The mean percentage and number of T-lymphocytes in this group were normal. Eight patients with nodular lymphocytic lymphoma and 2 patients with nodular lymphocytic-histiocytic lymphoma had normal mean numbers of CRL but decreased numbers of T-lymphocytes. Of 6 patients with diffuse lymphocytic lymphoma, 4 had elevated percentages and numbers of CRL. Despite low percentages, normal numbers of T-lymphocytes were found in 3 of these patients.

Hepatic toxicity associated with gold therapy.

Three patients with rheumatoid arthritis developed jaundice after initiation of chrysotherapy. Gold sodium thiomalate had been administered in dosages of 37.5, 60, and 110 mg in these patients before the onset of jaundice. Liver function studies indicated a cholestatic jaundice in all subjects. One patient underwent exploratory laparotomy because of progressive jaundice. Liver biopsy was done in two patients. In one patient significant bile stasis and thrombi were seen in the biliary tree. In another patient liver biopsy showed ballooning of hepatocytes with minimal cholestasis. All patients recovered spontaneously. Awareness of this rare complication may prevent unnecessary diagnostic and surgical procedures in patients with rheumatoid arthritis who may develop jaundice while receiving chrysotherapy.

Immunological identification of subpopulations of mononuclear cells in sarcoid granulomas.

The quantity of both circulating B and T lymphocytes in patients with sarcoidosis is diminished, although the relative percentage of each cell type appears normal. Immunocompetent cells comprising B and T lymphocytes, plasma cells, and histiocytes have been recognized in the sarcoid granuloma and the implications of these findings have been discussed.

Immune function in sarcoidosis. Studies on delayed hypersensitivity, B and T lymphocytes, serum immunoglobulins and serum complement components.

An assessment of immune function was performed in twenty-four patients with recently diagnosed active sarcoidosis. Four patients manifested skin anergy to four antigens. All subjects except one were capable of generating a positive skin response to a croton oil patch test. The incorporation of [3H]thymidine by lymphocytes in vitro in response to the nonspecific mitogens--phytohaemagglutinin, pokeweed mitogen and Con A did not differ between anergic and non-anergic thymidine incorporation in vitro when stimulated by the specific antigens, streptokinase/streptodornase or Candida albicans. Lymphocytes obtained from nine of eleven patients having positive delayed hypersensitivity skin reactions demonstrated MIF production in vitro upon specific antigen challenge. Quantities of circulating B and T lymphocytes did not differ between anergic and absolute numbers of circulating B and T lymphocytes, as well as hypercomplementaemia and hypergammaglobulinaemia when compared to the control group.

Lactic acidosis in diabetic patients.

Plasma lactate and beta-hydroxybutyrate concentrations were measured during episodes of ketoacidosis and lactic acidosis in diabetics. In 39 patients with ketoacidosis, with a mean plasma beta-hydroxybutyrate concentration of 12.4 millimols/liter, the plasma lactate concentration was less than 3.6 millimols/liter in 28 and moderately elevated in 11. In seven of the latter, coexisting lactic acidosis had been suspected clinically. In these 39 patients, there was no correlation between plasma lactate and beta-hydroxybutyrate concentrations. In six of ten episodes of presumed and later proved lactic acidosis, despite negative or weakly positive serum reactions with sodium nitroprusside, the plasma beta-hydroxybutyrate concentration was elevated. Although positive, the serum reaction with nitroprusside was also misleadingly weak in five of 39 patients with ketoacidosis, including three with plasma lactate concentrations less than 3 millimols/liter.

Acute anaphylaxis associated with serum complement depletion.

A 45-year-old woman with rheumatoid arthritis developed anaphylaxis 6 min after receiving a subcutaneous injection of lidocaine, followed by an intra-articular injection of lidocaine mixed with methprednisolone acetate. One hour after the onset of anaphylaxis, serum complement component levels were markedly depressed and remained so far 18 hr. Circulating immune complexes and antibodies to lidocaine could not be demonstrated. Neither lidocaine nor methylprednisolone acetate activated the patient's complement system in vitro. Subsequently, total hemolytic activity (CH50) levels were variable, complement component protein concentrations of C1q, C1s, C4, C2, C3, C5, C6, C9, and Factor B were normal, but hemolytic activity of C4 and C2 was diminished. Serum C1 inhibitor concentrations were normal or slightly depressed. The patient has never had any symptoms suggestive of angiodema. It is postulated that the endogenous complement abnormality present in this patient may have contributed to the anaphylactic reaction.

Association of polyarthritis, subcutaneous nodules, and pancreatic disease.

A patient with nodular liquefying panniculitis, polyarthritis and an occult pancreatic neoplasm is described. The skin lesion was initially mistaken for erythema nodosum. Subcutaneous and synovial fluids demonstrated similar negatively birefringent, rectangular particles, lying in between fat globules. Serum lipase,although continuously elevated, did not fluctuate with disease activity. Biochemical evidence of lipolysis in either the synovial fluid or serum was not demonstrable. Immunologic mechanisms appeared not to be involved in the pathogensis of the panniculitis or the arthritis.

Diagnosis of sarcoidosis by lip biopsy of minor salivary glands.

In two patients with bilateral parotid gland swelling of unknown etiology the diagnosis of sarcoidosis was established by lip biopsy of the minor salivary glands. This simple, innocuous biopsy procedure may prove useful in tissue documentation of sarcoidosis.

Observations on immunochemical assays of human chorionic gonadotropin.

Commercial immunochemical tests, "UCG" and "Prepuerin", detected standardized human chorionic gonadotropin (HCG) in concentrations comparable to the rat ovarian hyperemia test. These in vitro systems also cross-reacted with pituitary luteinizing hormone (LH) but not with follicle-stimulating hormone (FSH) of animal origin. The latex agglutination slide tests required a higher concentration of HCG for a positive test than did the bioassay. In cases of abnormal pregnancies the immunochemical assays remained positive longer than the bioassay, which is apparently due to their detection of biologically inactive HCG. Several non-pregnant patients with ovarian cysts and cystic teratomas excreted in their urine some substances which reacted with the UCG test. After surgical removal of the tumour these substances disappeared from the urine.

Immunologic characterization of the mononuclear cell infiltrates in rheumatoid synovia, in rheumatoid nodules, and in lip biopsies from patients with Sjögren's syndrome.

Two subcutaneous rheumatoid nodules and 8 rheumatoid synovia from patients with rheumatoid arthritis (RA); and 2 parotid glands, 1 "pseudolymphoma," and 6 lip biopsies from patients with Sjogren's syndrome (SS) were studied to identify mononuclear cells. The palisading mononuclear cells in subcutaneous nodules had a surface membrane receptor for complement. B lymphocytes surrounded by larger numbers of non-B lymphocytes were found in RA synovium and between salivary ducts of SS lip biopsies. A "pseudolymphoma" obtained from a patient with SS consisted primarily of B lymphocytes. The predominant mononuclear cell in rheumatoid synovia and salivary glands in patients with RA and SS do not have surface membrane receptors from complement and are thus probably T lymphocytes or null cells.

[New aspects in the diagnosis of intervertebral disk displacement of the upper lumbar spine with special reference to magnetic resonance tomography].

A report is presented on two patients who received surgery on a disc prolapse between the lumbar vertebrae 4 and 5 as treatment for compression of the fifth lumbar root, but in whom the clinically relevant disc prolapse was located higher (lumbar vertebrae 1/2 or thoracic vertebra 12/lumbar vertebra 1). Magnetic resonance tomography made a major contribution to the later diagnosis of the high disc prolapses. Besides precise localization of the lesion, MRT made it easier to understand why such a high disc prolapse can cause a compression syndrome of the fifth lumbar root.
