[Clinical and biochemical characterization of isoniazid-induced auto-antibodies].

Isoniazid (INH) is one among many drugs capable of inducing autoantibodies and, in some cases, a lupus-like syndrome (LE). A longitudinal study was performed in 24 tuberculosis patients treated with INH to detect antibodies (A-AH) to total histones and fractions. Antinuclear antibodies were observed in two patients after treatment. Higher frequency of IgM-AH was also observed. IgM-AH binding to all fractions were observed in those serum samples exhibiting stronger ELISA reactivity. Conversely, binding to only H1 occurred when lower IgM-AH activity was tested. Correlations with clinical expressions of LE were not observed in the present study.

[Lactic dehydrogenase in the serum and saliva of clinically normal subjects].

The activity of lactic dehydrogenase in the serum and the saliva of the right and left parotid glands was determined in 32 individuals considered clinically normal. They were divided in groups according to the sex and the age. There was no difference of lactic dehydrogenase activity related to age and sex.

[Determination of the fraction of C3c complement by radial immunodiffusion in the serum and saliva from the parotid gland of clinically normal subjects].

It was our intention to determine the C3c fraction in the serum and in the parotid saliva of 13 clinically normal individuals by the radial immunodiffusion method. The mean value of the seric C3c was 86.92 mg/dl and the confidence levels averaged 75.53 to 100.31 mg/dl. There was no measurable concentration of C3c in the parotid saliva.

Association of anti-DNA and anticardiolipin antibodies in systemic lupus erythematosus.

Recent studies have shown that anti-DNA and anticardiolipin antibodies in patients with SLE may cross-react. Using an ELISA for determination of these antibodies, a strong association between IgG anti-denatured DNA and IgG anticardiolipin antibodies was found. Eight sera samples with the highest levels of both antibodies were selected to determine the possibility of a cross-reaction. The levels of anticardiolipin were not affected by denatured DNA in concentrations adequate to inhibit the anti-DNA binding. These data did not confirm previous studies using monoclonal antibodies showing cross reactivity between the two groups of antibodies. Nevertheless, a population of antibodies that may cross-reacts, in some special cases, cannot be ruled out.

[Progressive systemic sclerosis, B-cell malignant lymphoma of the ileum and thyroid adenocarcinoma].

A patient with progressive systemic sclerosis with rapid evolution to death is presented. The post-morten examination revealed besides the typical changes of the progressive systemic sclerosis in the skin, kidneys, heart and blood vessels a B-cell ileal malignant lymphoma with generalized metastases, and an adenocarcinoma of the thyroid gland. A possible mechanism involved in the association of these diseases might be the action of the oncogenes modifying the cellular hormostasis and the immunological tolerance.

Nervous system involvement in systemic lupus erythematosus: report of three cases.

Central nervous system involvement in systemic lupus erythematosus is rather frequent whereas peripheral nervous system involvement is much less common. The three patients studied by us had isolated manifestations uncommon in nature. The first one developed a sensory-motor polineuropathy with signs of axonal degeneration. It responded to the therapeutic association of corticosteroids with an immunosuppressive agent. Satisfactory recovery took place over a time span of a year. The second patient had encephalic and cerebral trunk involvement from which an irreversible dementia resulted. The third patient, who had recurrent aseptic meningitis, is asymptomatic for six months now. Patients one and two had no systemic manifestations at the time of nervous system involvement. Suspicion of systemic lupus erythematosus was made on the basis of past inspecific articular symptoms. The neurological and systemic manifestations may be sometimes simultaneous; they are usually followed by serologic changes. Isolated nervous system involvement may be seen with and without sorologic changes, and there may be found antibodies reactive with phospholipids (anticardiolipin, antigangliosides and anticerebrosides). The employment of nonsteroid immunosuppressive drugs associated with corticosteroids in small doses seems to be useful in cases of systemic lupus erythematosus with nervous system involvement.

[A review of Lyme disease].

Lyme disease is an infectious disease caused by the spirochete Borrelia burgdorferi, transmitted by certain ixodid ticks. The illness usually occurs in stages with many different clinical manifestations. The disease starts with a typical cutaneous lesion called erythema cronicum migrans, that usually develops at the site of the tick bite. After weeks or months, some patients develop neurological abnormalities, particularly meningitis, cranial nerve paralysis, peripheral radiculoneuritis, or cardiac involvement, such as atrioventricular blockade, myopericarditis and cardiomegaly, or migratory musculoskeletal pain. Months or years later, many patients develop arthritis, which usually occurs in intermittent attacks for several years. Lyme disease was only recently recognized in the United States. However this borreliosis has now been recognized in every continent except South America. In this paper we review the clinical and laboratorial features of Lyme borreliosis and discuss the possibility of its presence in Brazil or other parts of South America, where it has recently been recognized that ixodid ticks are common.

Chronic active hepatitis associated with anti-liver-kidney microsome antibody type 1.

A 3 years old girl presented with clinical feature of an acute hepatitis-like illness, with jaundice, hepatosplenomegaly, high alanine aminotransferase activity (ALT) and high gamma-globulin values. We were able to demonstrate high titre of anti-liver-kidney microsome antibodies type 1 (LKMA1) in the serum of this patient using immunofluorescence, ELISA (Enzyme-linked immunoabsorbent assay) and Western blot (WB) analysis. This observation together with the liver morphology and after excluding other possible causes of hepatitis established the diagnosis of chronic active hepatitis associated with anti-LKM1 antibody. Immunosuppressive therapy was therefore started immediately.
