ABSTRACT
The zinc, an important enzymatic cofactor, is involved in many metabolic processes. Its deficiency might be due either to malabsorption or to excessive utilization. In the medical literature of the latest 10 years, zinc was considered to play a part in the immune processes. The authors of the present paper intend to study the zinc and immunoglobulin levels in various diseases, i.e., chronic progressive hepatitis, liver cirrhosis (LC), dermatitis, bronchial asthma. This preliminary investigation was carried out in 30 patients with LC in whom serum zinc values were assayed by atomic absorption spectrophotometry and the immunoglobulin levels were determined using the Mancini type simple radial immunodiffusion technique. All these patients presented considerable decrease of serum zinc concentration, the values ranging between 3.06 and 7.65 mumol/l as compared with 19.8 +/- 1.5 mumol/l in the controls, alongside with the increase of immunoglobulins G and M. In the patients treated with Zincum metallicum CH5 it was observed after about 30 days of treatment that the clinical state was considerably improved and IgG and IgM as well as serum zinc had resumed their normal values. This treatment should not be interrupted since in LC, without permanent additional supply, the serum zinc returns rapidly to the initial deficit or even lower.

The influence of oral zinc sulphate therapy on the humoral immunity was investigated by dosages of serum immunoglobulins (Ig) and of plasma zinc levels in 12 patients with a mean age of 70 years, in comparison with other 11 patients treated with placebo and with a control group of 50 apparently healthy subjects. The results of this double-blind study demonstrated the zinc effect on the immunoregulation, as the Ig levels, and particularly those of the IgG class, initially high, were lowered in a statistically significant proportion. It is assumed that further clinical trials with various zinc concentrations could bring more information on this trace element participation in the humoral immunoregulation.

The effect of zinc supplementation of chelation therapy in saturnism was studied in 20 patients hospitalized in the Clinic of Occupational Diseases of the Colentina Hospital. In 10 patients 400 mg/day zinc sulphate in two uptakes was administered concomitantly with the chelation therapy. The other 10 patients received only chelation therapy. The period necessary for the correction of the anemic syndrome was estimated comparatively by studying the evolution of the following parameters: hemoglobin, reticulocytes, red blood cells with basophilic granulations. Zinc supplementation of the chelation therapy had a favourable effect by reducing the necessary period for the correction of anemic syndrome.
