SODIUM CACODYLATE IN SYPHILIS

To the Editor:—I was much interested in the study of this subject by Dr. H. N. Cole (The Journal, Dec. 30, 1916, p. 2012.)

In 1913 I treated a series of cases of syphilis with sodium cacodylate; but, not getting the desired results, I discontinued its use. In 1915, I became interested again because of the writings of Dr. J. B. Murphy, and applied it in three cases in which the patients had initial lesions:

Case 1.—J. M., man aged 21, single, shoeworker, came to me with an initial lesion of the penis to the right of the frenum. I began intramuscular injections of sodium cacodylate, 5 grains, in ampules made by Parke, Davis & Co., every day for ten days. Then I halted for ten days and repeated ten more injections. The sore on the penis entirely disappeared about the ninth day. There was a slight, faintly macular eruption of the forearms and abdomen, which soon disappeared. There was no alopecia. When he returned, after the last series of ten injections, there were mucous patches in the throat and some involvement of the left tonsil. I put the patient on mixed treatment, which cleared his throat. He had, at end of twenty doses of 5 grains of sodium cacodylate each, a positive Wassermann reaction. After mercury and potassium iodid for two months there was a positive Wassermann reaction. To date, after three salvarsan treatments intravenously there have been two negatives.

Case 2.—F. S., man, aged 28, married, machinist, had an initial lesion on the penis. Treatment with sixty injections of 5 grains of sodium cacodylate gave results as follows: The initial sore on the penis disappeared in ten injections; there were severe mucous patches of the mouth; the tonsils were badly infected. There was a positive Wassermann reaction. There were syphilids of both arms and shins; marked papular eruption; malaise, and a slight trace of albumin in the urine. I placed the patient on mercurials and at last give him three salvarsan injections three weeks apart. The result was a negative Wassermann reaction, the skin was clear and the patient felt fine.

Case 3.—D. C., woman, aged 21, single, seamstress, had an initial lesion on the left side of the cervix, and a macular eruption on the face, neck and shoulders, and also, though faint, on the forearms. Thirty injections of sodium cacodylate of 5 grains each were given. The initial lesion disappeared in one week. Mucous patches of the mouth appeared and persisted. The Wassermann reaction was positive. I gave mercurials and potassium iodid for seven months, and salvarsan once. The Wassermann reaction is now negative.

My conclusion after two trials of the use of sodium cacodylate in small or large doses is that it has no effect toward curing the condition; in fact, the throat symptoms were seemingly increased in severity by its use. It has no effect on syphilids of the forearms and shins, and if anything makes them worse.

It improves the appetite, as one would expect. It has some effect on the kidneys, as noted in Case 2; it has some effect in healing the initial lesion, as noted in all three of this series; why, I do not know.

I am entirely satisfied that it has no beneficial effect on syphilitics and have discontinued its use entirely in my practice.

I am glad to have read Cole’s excellent article, as it shows me that I was correct in my decision not to use it again, as it was worthless.

To the Editor:—Dr. William G. Ward’s letter (The Journal, Feb. 3, 1917, p. 390), and the recent admirable article by Dr. Harold N. Cole (The Journal, Dec. 30, 1916, p. 2012) recall to mind Dr. J. B. Murphy’s clinical note on the use of sodium cacodylate in the treatment of syphilis (The Journal, Sept. 24, 1910, p. 1113), and the experimental work of Cap. H. J. Nichols, U. S. Army (The Journal, Feb. 18, 1911, p. 492). The results of Nichols’ work conclusively proved, at least from a laboratory standpoint, that this drug was of very little value as a spirocheticide in combating syphilis. Prior to the publication of Dr. Murphy’s letter I had employed sodium cacodylate extensively as a remedy in psoriasis, and I still continue to use it in selected cases of the disease.

Adopting Dr. Murphy’s suggestion, I gave the agent an extensive trial in syphilis in all stages of the disease. The results were extremely disappointing, from both clinical and serologic points of view. More recently, during the scarcity of salvarsan, I gave the drug a second trial, employing it in large dosage in the hope that the previous failure had been due to the employment of insufficient amounts. The results were not tabulated, but, judging roughly from my experience in a score of cases, its therapeutic value as an anti­syphilitic was nil. A few of the patients underwent a temporary improvement, probably owing to the tonic effect of the drug, but in every instance the serologic findings were unaffected.
