THE Subcutaneous Use of Chloride of Gold and Sodium with Iodide of Manganese in Pulmonary Tuberculosis. By WILLIAM S. BOARDMAN, M. D. [Reprinted from the Boston Medical and Surgical Journal of May 17,1894. THE TREATMENT OF PULMONARY TUBERCU- LOSIS BY THE SUBCUTANEOUS USE OF THE CHLORIDE OF GOLD AND SODIUM WITH THE IODIDE OF MANGANESE. BY WM. S. BOARDMAN, M.D., BOSTON. We have read and heard so much about new remedies and modifications of new remedies for the treatment of phthisis, that now to many the subject fails to excite an interest. The methods of treatment are too numerous to men- tion. One is almost startled by the list of drugs and methods proposed, in reading Solis-Cohen’s article on “ Tuberculosis,” in “ Hare’s System of Practical Thera- peutics.” Yet there must be something beneficial in these remedies, even if there is nothing specific. The brilliant methods of Koch, dimmed by the noxious elements in his tuberculin and brought to a glow again by the researches of Klebs and Hunter, are undoubtedly more for good than anything hitherto proposed. Although we seem so near the desired re- sult, it has not yet been obtained in the ideal that was first conceived; nevertheless, it behooves us to make the most of what we have, while striving for something better. From the earliest time, the attempt has always been made to combat the marasmus of phthisis by dietetic and hygienic measures. How slow and uncertain a procedure it has been is only too well known to us all. If in any way we can aid the process of nutrition and maintain or increase the strength of the patient, a great deal will be done towards staying the disease, if not directly tending to a cure. 2 One mode of treatment that has been tried consider- ably yet spoken of by comparatively few writers, is the subcutaneous use of a solution in glycerine, of the chloride of gold and sodium with the iodide of manga- nese. In March, 1891, an article in the Medical Record, by Dr. J. B. White, extolled this combination as a treatment for phthisis, and cited a number of cases to show the beneficial results obtained. Another article in September, 1892, by the same author, ap- peared to supplement and confirm the results of the first paper, being written in a very earnest and pleas- ing manner. As the combination of the chloride of gold and sodium with the iodide of manganese, is, under ordinary circumstances, likely to result in the forma- tion of a precipitate, the author of the above-mentioned articles was asked to state the method of preparing the solution. Since the process was not given and the injection fluid could only be obtained in New York, it was thought to be of sufficiently scientific interest to the profession to have an analysis of Dr. White’s pre- paration; and Mr. Wm. C. Durkee, Ph.G., kindly consented to undertake the chemical work with this result. “ The proximate chemical examination of the injec- tion fluid is as follows. It has a dark-amber color, with a specific gravity of 1,260, a styptic taste and a syrupy consistency. “According to Dr. J. Blake White’s statement, each drop should contain the equivalent of one-fiftieth of a grain of the chloride of gold and sodium, and one- fiftieth of a grain of the iodide of manganese, that is, each drop should represent one-twenty-fifth of a grain of the combined salts. “ He does not mention the method of obtaining the drop, whether from the bottle or a medicine-dropper; and although changes in the viscosity of the liquid owing to the temperature, the rapidity with which the drops are formed, and the shape of the material from which the drop falls largely govern the size, it was assumed that a drop from the original five-cubic-centi- metre bottle, at about 70° F., and forming at a speed of one in two and a half seconds, would be about the size usually obtained and probably intended by the quoted statement. “ Several careful weighings of ten-drop quantities of the liquid were made and the drops found to average 77 milligrammes each, and supposablv contained one- fiftieth of a grain (.0013) of U. S. P. strength of chloride of gold and sodium, and the same quantity of iodide of manganese, or 169 mg. of each in 10 gm. of injec- tion. “Ten grammes of the fluid were found to contain .01737 gm. of metallic gold, equal to .05352 gm. chloride of gold and sodium U. S. P., or about one-third the amount claimed. The liquid is composed mainly of glycerine, and contains free iodide, iodine in the form of iodate (also as iodide), chlorine, sodium, potas- sium and manganese. “ As the method of preparing the injection fluid recommended by Dr. White was not made public, the following process has been devised, which yields a solution containing the ingredients he has reported as useful and of the strength he recommends. Take of 1 Gold and sodium chloride, D. S. P. . . . 1.69 gm. Manganese sulphate 2.44 gm. Potassium iodide 4.62 gm. Diluted alcohol . 10.0 c. c. Glycerine » Distilled water j of each a sufficient quantity. “ Dissolve the gold and sodium chloride and one gramme of potassium iodide separately, in sufficient glycerine to make each solution weigh 25 gm. using only a very gentle heat, if any ; when cold mix the two solutions. Dissolve the manganese sulphate in sufficient distilled water to make 10 c. c., and 3.62 gm. of potassium iodide in sufficient diluted alcohol to make 10 c. c.; mix the two solutions, and allow the contain- ing vessel to stand in powdered ice for several hours, to thoroughly precipitate the potassium sulphate. Then decant 10 c. c. of the clear liquid into 40 gm. of glycerine ; evaporate on a water bath until the total i It is best to prepare this chemical or to use an article which is known to be of full strength, as market samples were found to con- tain less gold than the labels indicated. 4 weight is reduced to 40 gm., aud add glycerine to make 50 gm. Mix this solution with the solution of gold and sodium chloride, and keep in amber glass-stoppered bottles. Each 77 mg. (about one drop) contains the equivalent of mg. (one-fiftieth of a grain), of gold and sodium chloride and the same quantity of manga- nese iodide.” The injections were given in the forearm, upper arm and subclavicular region by an ordinary hypo- dermic syringe. The solution prepared has been used in the manner advised by Dr. White, the initial dose usually being one drop (equal to one-twenty-fifth of a grain of the com- bined salts of gold and manganese) diluted with a few drops of a one-per-cent, solution of carbolic acid, and increased only as the constitutional disturbance re- mained at a minimum or ceased to appear after several doses. In some patients the reaction appeared within two hours — as headache, backache and general malaise — lasting twenty-four to forty-eight hours; in others it was but little marked and disappeared within one or two hours after an injection. The pulse has been found to be full and slow with subnormal temperature in some, while in others the pulse was increased in rate with a slight rise in tem- perature. The local effect varied, in some the solution caused considerable inflammation, in others the injection was only marked by an induration and slight tenderness about the puncture. It seemed to depend upon the amount of loose connective-tissue present and the in- dividual susceptibility to irritation. Cough-mixtures, tonics and hygienic measures have also been made use of as opportunity permitted. One thing was observed quite generally, as noticed by another writer — within two weeks or thereabouts after beginning the injections, the appetite was in- creased, so much as to cause the remark of the patient to the effect. The cough and expectoration in some were lessened, TREATMENT WITH SUBCUTANEOUS INJECTIONS OF GOLD AND MANGANESE (Dr. Boardman). No. Sex. Age. Social Condition. Occupation. Family History.

Night-sweats usu- ally ceased. The general appearance and feelings of the patients improved, and they did not hesitate to declare themselves greatly benefited. On making a physical examination of a patient after a few injections, the former condition of things may be somewhat aggravated. At such a time I have found the signs more marked, especially the auscultatory signs ; later the results were variable. The theory that the preparation of gold is eutrophic, while the manganese is anti-auaemic, seems to be well borne out. That an improvement can be secured in some cases I feel quite confident, but as to complete and permanent recoveries I am not so certain. The exact way in which these injections affect the pulmonary tissue is more or less a matter of conject- ure ; nevertheless, the remedy appears to act as a tonic to the waning strength of the patient, also to cause a certain amount of irritation and inflammation around the foci of infection (as sometimes shown by bloody sputum after a large dose), which may eventually re- sult in an encapsuling of the pathological portions, or their replacement by dense fibrous tissue. However, be it as it may, the subcutaneous use of the chloride of gold and sodium with the iodide of manganese certainly improves the majority of patients subjectively; and if a cure does not result, they are at least in a most promising condition for treatment by modified tuberculin or its allied products. The strong- est argument in favor of this treatment is the fact that when properly given no injury can be done, while there is great probability of an improvement if not a cure. Appended is the full report of ten cases treated by gold and manganese, also the tabulated report of fifty- four cases, — some having been treated with gold and manganese, and some with Hunter’s modification B. (kindly furnished by Dr. Trudeau of Saranac Lake, N. Y.). In regard to the latter method of treatment, I will briefly state, that while not obtaining the results of 6 Dr. Trudeau, I found much in its favor to warrant a further trial. I have also been using for several months Klebs' Tuberculocidin, and so far with considerable satisfac- tion. In connection with this paper, I wish to thank Dr. E. M. Greene for his valuable services in the exami- nation of sputum, and Dr. F. C. Cobb for laryngeal work, also Mr. Wm. C. Durkee, Ph.G., for most per- fect chemical work, and Dr. E. O. Otis for kindly suggestions.
