The authors report a new case of partial immune deficiency of cellular immunity, associated with chronic mucocutaneous candidiasis in a 12 Years-old boy. The disease began very early during the first few weeks of life, with thrush in the mouth. This candidiasis then evolved intermittently and was still present. Numerous cutaneous, pulmonary and ear infections occured throughout this child's life. This morbid association led to a search for an immune deficiency. Humoral immunity was normal. Abnormalities of cellular immunity were as follows: apart from candidine skin anergy, there was a deficiency in the factor which inhibits leukocyte migration, secretion of a factor favouring this migration (MEF). It was also noted the presence of the patient's serum, of a factor inhibiting lymphocyte transformation in the presence of candidine. In spite of treatment with intravenous route, amphotericin B, followed by transfer factor, the oral candidiasis persisted together with the skin anergy to candidine. On the other hand, the serum inhibitory factor disappeared. Pulmonary cryptococcosis probably favoured by corticosteroid treatment, developed on this background of immune deficiency; as usual it spread to the meninges. Treatment associating intraveinous amphotericin B and 5 fluorocytosine oral and later intravenous, total duration 6 months, grave a recovery maintained on a 8 months follow up.

During the last six years, the search for a deficiency in alpha-1-antitrypsin (AAT) was carried out in 106 children aged from 5 months to 14 years, having the obstructive pulmonary syndrome. Nine deficiencies were in this manner detected and phenotyped. These are the observations of three of these children which are reported here. Their age ranged between 4 years and a half for two of them and 8 years for the third one, having asthma. The phenotypes are respectively SS, MZ, and ZZ. Following these observations, the problems brought up by the association in AAT deficiency and the obstructive pulmonary syndrome in children are discussed: clinical symptomatology, interpretation of the basic design, pathogenic signification and possible connections with asthma and therapeutic influence. The functional respiratory disorders noted in these children involved a ventilatory asychronism, an overexpansion, and regional abnormalities of ventilation and perfusion. To answer these still outstanding questions, the need for a systematic prospective study carried out on a wide group of children is emphasized.
