The present paper describes the clinical and laboratory follow-up of 11 patients with the diagnosis of common variable immunodeficiency. Their age varied from 8 to 45 years. The mean disease time was 12.6 years and mean diagnosis time 4.3 years. Infectious manifestations, mainly of the respiratory and digestive tracts, occurred in all patients. Polyadenomegaly was noted in seven, hepatomegaly in six, splenomegaly in five and arthralgia in four patients. All of them presented serum IgG less than 250 mg/dl. IgA less than 33 mg/dl and IgM less than 31 mg/dl, except one with IgM = 176 mg/dl. The isohaemagglutinin titers were less than 1/20 in all but one patient. The determination of the number of B lymphocytes in the peripheral blood revealed normal counts in three, elevated in one and decreased in five patients. The CD-4/CD-8 ratio was less than 1 in 8 and greater than 1 in three of them. Five patients had positive cutaneous late reactions to at least one of the following antigens: PPD, SK-SD (Varidase), Trichophytin and Levedurin (Candidin). A decrease of the proliferative activity of peripheral blood mononuclear cells stimulated by lectins (PHA, Con-A, PWM) was also noted. Natural killer function was decreased. The association a possible role of regulatory lymphocytes in the immunopathogenesis of this disease. The data presented here emphasize the diversity of clinical and immunological manifestations of this disease, which could be noted between diverse patients and in the follow-up of a single one. In our cases the disease had an evolutive character, with a primarily humoral dysfunction followed by cellular immunity disturbances that determined poorer prognosis and progressive difficulties in the therapeutics. We suggest a conceptual reevaluation of this condition and a new denomination, for instance "Late-Onset Combined Immunodeficiency". The long delay between the initial clinical manifestations of the disease and its diagnosis was a handicap for an adequate treatment. Early intervention could certainly decrease the morbidity and mortality of the disease.

T-lymphocytes and their subsets were determined in three patients with classical Kaposi's sarcoma. A reduction of pan-T-lymphocytes, including both a reduction of T-helper and T-suppressor cells, was found in one patient. None of the patients showed a reduction of the T-helper/T-suppressor cell ratio, as described in the lymphadenopathic disseminated type of Kaposi's sarcoma. Intradermal testing with tuberculin and trichophytin gave no indication of humoral immunodeficiency or anergy. In addition to electron beam irradiation, one female patient was treated with rIFN-alpha-interferon, 6 X 10(6) IU 3 times a week over a period of 3 months, and 18 X 10(6) IU 3 times weekly over 1 month. Under this therapy, irradiated as well as nonirradiated lesions become flatter, reduced in size and faded. The number of T-suppressor cells diminished.

Delayed hypersensitivity skin testing was performed in 129 critically ill patients. Six intradermal antigens were used: tuberculin, candidin, varidase, epidermophytin, trichophytin and CCB (a polyvalent microbial vaccine from the Pasteur Institute). The response was judged as positive when one test or more were positive. Patients were devided in four groups: group A (40 cases): non-infected patients, a priori without immunodeficiency; group B (14 cases); suspected of immunodeficiency (cancers, hemopathies, collagen diseases receiving corticosteroids); group C (24 cases): decompensated chronic respiratory insufficienceis; group D (50 cases): overwhelming sepsis (septicaemias, septic acute respiratory distress syndromes, thoracic empyemas, purulent meningitis, peritonitis, mediastinitis). A significant diminution of delayed hypersensitivity was observed in groups B, C and D. No relation was found between delayed hypertensitivity and prognosis in groups C and D.

A cellular immunodeficiency was revealed in a 39-year-old female patient suffering from Werner's syndrome. Relevant findings were negative intracutaneous tests to candidin, trichophytin, tuberculin and bacterial antigens, reduced lymphocyte response to PHA, and impaired intracellular killing of Candida albicans by granulocytes. The inclination of patients suffering from Werner's syndrome to develop neoplasms may be related to this immunodeficiency.
