A series i1f facts which tend to corroborate the hypothesia of ~ interrclationship may ~ summarized briefly u followa: l . Leprosy is a much older disease than tuberculosis. IJa those cDumtrie.s where the epidemiologica&#39;l curve of tubeacu· losis is rising, leprosy is a health problem; whfie in thote countries where that curve is falling, leprosy ls eitber a rela· tiveJy small health problem or none at all. Tuberculosis ia an urba.n d ise.ase, but leprosy is a rural one (6). 2. The change brought about by Mvcoba.ete• *"&#39; ~ • wm in the capacity of an organism to react migbt influence the cout·s-e of anothcr diseasc which, like ·leproay, fs produeed by a cJose ly similar mycobacterium. A primary infection witb tuberculosis might a!fcct thc clínical aspect and courae of leprosy by producing allergic and therefore rélatively berdp forms (8, 6, 8, 11, 16) . 3. St udies of thc Jcpromin reaction in groups of healthy persons in countries where leprosy is not endemic show per&#39;· centages oC lepromin po~itives fluctuating, in dlfferent repor\a, between ~O and 74. It is almost eertain tbat the percentap of pos itivenes~ i ~ dul&#39; to n relat ive eo-immunity fnduced by a prior infection with t he K oc h bacillus (1, &#39;· 7, 12, lt, 17) • . 1 Tranalntion, !l<l m~...,. ha t modi.t1ed, of • papc&#39;l&#39; read at. tbe Thtrd Paa- Amclriean Lcproay C<mt..ren~.

Wben healthy , lepromin -negative pcr sons are inj E.oc t~ with BCG, the r eaction becomes positive in most cases; t hj:i is alBo confirmed by animal tesls (2, s. 9, IS , 1&#39; ). On the basis of theae factg we began an inve~tigati on of the influenc.e of BCG vacc.ination on Mitsuda-negati v<: leprosy ¡iatienta to determine if the lcpromin r enot ion would ~ubsequently become pos itivc. Such an effect would, of course, be o.f unquestionable value with r espect to t hc progu o~ i s of thc disea.se. MATERTAL ANI> METHODS Our first CJC.per imentsl group consisted of llS pútients with lepromatoWI leprosy , tbe lesions of which had disappeared aft er treatment with diasone or promin. but who were all negat ivc to lepromin.

Mitsuda Reaction alter BCG 861 COMMENTS Tite results, which show that the Mitsuda reaction beeame positive in 46 ( 40.7%) of the 113 lepromatous cases included in Tablea 1 and 2, are rather encouraging from our point of view. The problem of responsibility in discharging patients from the leprosaria is partly solved when it is known that, in an important percentage of those who become bacteriologically negative, the reactivity to the Mitsuda test can be changed to positive by BCG vaccination. The observations a~ regards the cases . of the indeterminate form which were negative to lepromin, we are inclined to &#39; ~elieve, almost solve the problem of preventing the hitherto frequent transformation of these cases to the lepromatous type. . For the purpose of studying the type of tissue reaction ··evoked by BCG, we subjected several of the positive Mitsudareaction lesiona to biopsy and found that they were also strueturally positive, i.e., of . tuberculoid aspect. Subsequent observations of sorne of the patients in our records show that the use of larger doses of BCG, given either in a single injection or by revaccination, improves the resulta. Not only are the percentages of positivity increased, but the Mitsuda reactions obtained are stronger. By comparing the findings of the so-called discordant reactions, it is noticed in Table 1 that 45 per cent became tuberculin positive compared with only 2.5 per cent in Table 3, while in the latter group 42.5 per cent became lepromin positive compáred with only 2.0 per cent in the former one. These facts demonstrate clearly that the respective phenomena of the tuberculin and lepromin reactions evoked by BCG are completely different, and it seems certain that they depend upon different mechanisms. lf we compare the percentages of positivity of the Mitsuda reaction obtained after BCG vaccination in the two groups of . patients, we find th.at the anergy of the indeterminate cases is Il\UCh less profound than that of the ·le}>romatous ones. Worthy of special mention are two cases oí the indetenninate form in which the diffusion of lesiona, as well as tbe strongly positive bact.E>riolo&&#39;ical findings and their negative • reactions to lepromin, madt· ••~ ~U~tJ.W>Ct that a transformation to the lepromatous ty~ was takin-i! olace. After revaceination with BCG these two cases b~amt iepromin J?OSitive and the elinical and bacteriologkal picture •as completely modifled. I1tternational Journal of Leprosy 1962 SUMMARY A atady has been made of the changes brought about, with rwpeet to reactivity to the Mitsuda test, by BCG vaccination of 118 leprosy patients of the lepromatous type whose lesione had disappeared after treatment with sulfone derivatives and who were all negative to lepromin prior to vaccination. Of th ese patients, 51 were negative to tuberculin and 62 were weakly (1+) positive. Of the 51 cases negative to both tests, 13, or 25.4 per cent, 1 beeame positive to lepromin. Among the 62 p~tients who were negative to lepromin but poeitive to tuberculin (l +), there were 33, or 53.2 per cent, whose Mitsuda reactions became positive. In a group of 40 patients with the indeterminate form of the dieeaae who were negative to both tests, the Mitsuda reaetion beeame positive in 35, or 87.5 per cent. . The results as ·shown by our case records lead us to thf! conclusion that BCG vaccination should be of value in solving the problem of discharge from the leprosaria, and that it should help to reduce the high incidence of transformation of cases of the indetenninate fonn, negative to lepromin, to the lepromatous type. T.he hiatopathological examinations which were made of some of the poeitive Mitsuda reactions obtained, proved them to be structuraJiy positive. RESÚMEN • Se estudió el cambio de la reacción de Mitsuda, después de la vacuna· ei6n BCG en 118 enfermos de lepra de tipo lepromatoso, lepromino negativos, cuJU !~iones habfan desaparecido después de tratamiento con derivados aullónicos. De este grupo ele pacientes 61 fueron negativoa a la tuberC!\llina 1 62 debilmente posit ivos (una +). · De loa 51 casos negativos para ambas pruebas, 13 o sea 25.4% viró la reacción de Mitsuda a positiva. De loa 62 pacientes negativos a la lepromina pero positivos a la tuberculina (una +) 33 o sea 63.2%; la reacción de Mitsuda viró a positin. En el grupo de 40 pacientes de forma indeterminada, negativos a anbu pruebas, la reacción de Mitsuda viró a positiva en 36 o sea 87.5"&#39;- Loe resultados obtenidos son una prueba de que la vacunación BCG ee ele iwaportancia en la solución del problema de las altas hospitalarias, ·uf como tambien en la reducción de la alta incidencia de transform&clÓil haeia el tipo lepromatoso del grupo indeterminado Mitsuda negativo. J:1 examen histopatológico hecho en algu!las de la reaccione• de Mit~ suda o~tenidas, demostró que eran estructuralmente nositivu. 20. 3 REFEIU::NCES l . A ZUt.AY, R. l J, 1111(1 CONVl&#39;r. J.
