Nowadays, infectious diseases are a topic of great interest in the scientific community.
One of the main issues concerns the spread of infections within hospitals. This is
not a new fact. Indeed, doctors and health facilities have always fought against the
spread of infections adopting new models, especially during the nineteenth and twentieth
centuries. One of the most emblematic infectious diseases in Europe during the last
centuries was tuberculosis (TB).
Throughout history, many terms have been used to refer to tuberculosis [1]. Consumption,
phthisis, mal du siècle and white plague are some of them. This variety of names is
probably due to the difficulties in a proper diagnosis of TB [2]. Indeed, the symptoms
of the infection may significantly differ in subjects. Starting from the end of the
nineteenth century, thanks to scientific progress, the scientific community was able
to understand the disease and, most importantly, to develop an efficient medical treatment.
It is interesting to underline that the treatises on psychiatry of the late nineteenth
and early twentieth centuries highlighted the close connection between neuropsychiatric
disorders and TB [3]. Indeed, in some scientific articles, some mental alterations
diagnosed with TB were indicated as “tuberculous madness”.
In particular, in those years, the symptomatology of tuberculosis was well-known and
therapies made substantial progress with Forlanini’s pneumothorax, while the treatment
of mental illnesses was still hinged on substantially ineffective means, to the point
that the mental hospital population was always growing in number.
Problematic conditions of asylums such as the scarcity and the decay, the poor hygienic
conditions, the overcrowding and the lack of clinical registration are well-known.
In this regard, the complaint by Minister Giovanni Nicotera in an “Inspection on the
asylums of the Kingdom” in 1891 is interesting. Indeed, in Italy, medical and political
debates were leading the first law on asylums, promulgated in 1904.
Because of the conditions mentioned above, asylums were considered places with a high
risk of contracting TB. How did doctors deal with this disease in asylums and what
prevention strategies were introduced?
We would like to present an interesting article published in the Rivista Mensile di
Psichiatria Forense, Antropologia Criminale e Scienze Affini—Journal of Forensic Psychiatry
and Criminal Anthropology—entitled “TB and Madness”, signed by Professor A. Grimaldi
and by Doctor F. Scotti, psychiatrists of the asylum in Milan [4].
This contribution that represents part of an oral communication at the Congress on
TB, which took place in Naples on the 25th–28th of April 1900, encouraged to investigate
the connection between mental illness and TB, in order to deal with a situation that
was starting to be worrisome: the spread of the disease inside the asylums.
In particular, this investigation was carried out through the following questions:
(i) Did TB cause neuropsychiatric alterations? Or (ii) Was mental disease a condition
that led to the development of TB? And (iii) Did TB cause, in the progenies of individuals
who were affected, a strong predisposition to the mental disease?
In this article, among the first considerations that the authors reported, it was
highlighted that serious signs of neuro-psychic degeneration were perpetuated in the
families that suffered from TB.
The references to the TB-madness link were also highlighted by other authors of the
time, as reported in this article: Baqué affirmed that TB represented one of the causes
that determine a general debilitation [5]; Morel argued that situations of poverty
and social unease, alcoholism, congenital and acquired diseases were the causes leading
to degeneration of the human species and this could be traced back to the Lamarck
thought: “all that nature has brought about or lost in individuals through the influence
of circumstances, it transmits through the generation to the individuals that derive
from it” [6].
The authors reported that the frequency of TB could also affect the health of subsequent
generations. Furthermore, the authors affirmed that TB was almost always present in
the genealogical trees of the alienated. A. Grimaldi then also referred to his publication
where, in the genealogical tree of a paranoid, he highlighted the presence of an ancestor
suffering from TB. The authors also underlined that other conditions as syphilis and
alcoholism could be associated with neurodegenerative diseases and psychopathological
conditions, and also that these conditions were hereditary. These researchers believed
that “this occurred because some infectious diseases acted more than others on the
nervous system, decreasing the vital energies of the organism and making it unsuitable
to transmit to the descendants the power to arrange according to the normal evolutionary
rules and the resistance to the various morbid influences”.
The authors opened an investigation at the main asylums, health homes and other institutions
in Italy by sending a questionnaire with the following inquiries and questions:
What was the total number of insane hospitalized in the institute with gender distinction?
How many were recognized as suffering from TB in the last five years, and how many
improved or healed?
How many of them were affected by TB before entering the institute?
How many developed TB before or after the beginning of psychopathology?
Were there any hereditary precedents of the affected psychiatric patients?
How many times TB influenced the symptoms and the course of psychopathology?
Did the institute have an infirmary or a special infirmary section for TB?
The investigation showed that in a population of 16,157 alienated, in a five-year
period, 937 cases of TB were recorded and among these 802 died. In 71 of 343 cases
of TB, the disease occurred before entering the asylum. As for question number four,
the authors recorded that many institutes did not respond, even though many were witnessing
cases of TB increasing after mental disease. For the fifth question, the difficulty
of obtaining the anamnesis of interned subjects and the general lack of information
on patients did not provide a significantly readable statistical data.
Having collected the various answers to question number six, the authors supposed
that among the symptoms of TB that influenced neuropsychiatric pathology, there were
depression, irritability and deterioration of nervous energies. In some cases of TB,
however, there were developments and moments of rationality of patients. Finally,
regarding the last question, in almost all asylums, there was no separate section
for TB.
Finally, the authors pointed out that the number of TB in mental asylums in Italy
was significant and the mortality was high.
Many of the psychiatric patients affected by TB contracted the pathology inside asylums.
In most cases, TB occurred after psychiatric illness.
Furthermore, the authors identified that the isolation of TB in asylum was not guaranteed
and mental illness and the state of the nervous system aggravated during TB, apart
from a small number of cases.
The authors were convinced that the inescapable conditions of life inside the asylum,
the difficulty of diagnosing TB in the alienated when they entered the institution,
the absence of isolation and the crowding of psychiatric structures increased the
diffusion of TB.
Indeed, they also reported that the psychiatric patients, not yet recognized as suffering
from TB and entering the asylum, spread the disease. Therefore, it happened that those
not affected by TB who entered in the asylum to seek treatment for mental illness
risked contracting the disease.
The investigation carried out by the authors made it possible to ascertain a very
serious condition of contagion in the Italian asylums and hoped for the need for measures.
In particular, they thought of different solutions: (i) that all asylums were equipped
with a department for TB and (ii) the foundation of two or three regional sanatoriums,
intended to accommodate the mentally ill with TB (Fig. 1).

[4]
The problem was already evident, as the proposal to isolate TB affected in asylums
was also proclaimed in other countries. As mentioned by authors, in England, psychiatrists
planned to build independent sanatoriums to ensure the isolation of patients affected
by TB with mental diseases.
The work of A. Grimaldi and F. Scotti is interesting. It was published in 1902, twelve
years later, that R. Koch claimed to have discovered the first “remedy” for TB. The
end of the nineteenth century was full of hope for a definitive eradication of the
disease, and it is undeniable that great strides were made. But, unfortunately, no
ultimate solution was found in that period. The diagnosis of TB was a hard challenge
for the physicians, and it was with the use of the BCG vaccine in the second half
of the twentieth century that we can see a real turning point in the battle against
the white plague.
It can therefore be thought that the article presented here marked a stage of significant
interest especially for those who were engaged in the field of infectious diseases.
The epidemiological investigation that was attempted in psychiatric asylums to understand
the contagion of tuberculosis makes us reflect today more than ever and in particular
leads to consider that we must always be ready to change our health models to face
new challenges of medicine.
It is also necessary to underline that in Italy, tuberculosis has been eradicated
by the provision of a network of outpatient centres (anti-tubercular dispensaries),
which have developed diagnostic skills and epidemiological expertise, the latter capable
of tracing all infections and treating them in an appropriate manner.
In Italy, the first specialized hospital was inaugurated in 1900 in Budrio, a town
in the province of Bologna, and it housed 100 beds. The decision to build a sanatorium
not in a mountainous area was motivated by the intention to maintain patients in their
environment and climate close to the family context. The possibility of maintaining
their daily habits and the continuity of family emotional support were considered
favourable factors for achieving a more stable “cure”. This model of specialized hospital
was adopted in Bologna, Gries (Bolzano), Pineta di Sortenna (in the Prealps of Sondrio),
Livorno, Rome and Genoa [7].
The sanatorium therapy represented a palliative treatment for symptom control and
to stimulate the patient’s immune defences through the “air-rest-feeding” triad [8].
In comparison with what is happening today, we can believe that also the suspension
of this network and the concentration of acute medical intervention in hospital emergency
rooms can be another cause of a rapid spread of coronavirus in Lombardy.
