TOILET HABITS IN DRUG TREATED DOWNS:

A SURVEY ON 209 SUBJECTS.

Renato COCCHI MD, neurologist and medical psychologist

(Italian translation)

 Abstract

The records of 209 drug treated Downs who went to consultation to the same physician, had an examination as for toilet habits at the first visit and at the last checkup. The sample's coordinates are: 118 M + 91 F; M/F ratio = 129.67; chromosomal diagnoses: pure trisomy 21 = 89.48%; mosaicisms = 3.35%; translocations = 2.39%; only clinical diagnosis = 4.78%. Average age at first consultation was 71.21 months; at the last checkup was 130.16 months; average drug therapy lasted 59.57 months.

When we observe them according to prevailing forms, toilet habits so vary (.001): normal, from 70.81% to 87.55%; atonic constipation, from 13.40% to 3.83%; spastic constipation, from 6.22% to 3.83%; diarrhoea, from 1.91% to 0.96%; celiac disease, from 0.96% to 0.00%; mixed forms, from 6.70% to 3.83%.

The improvements in toilet habits have been related to i. The decrease of upper respiratory tract infections, and consequent cut-down of antibiotic therapies; ii. Motor activities' amelioration; iii. The increased intake of diet fibres, following an increased intake of diet vegetables and fruit; iv. The emotional threshold increase; all as effects of drug therapies in Downs, already reported in previous research.


Key words: Down’s syndrome; drug therapy; toilet habits.

The way usually Downs empty their bowel deserved very poor interest from researchers. This is a singular fact, since often this function brings recurrent troubles to the Downs and the parents. Perhaps the reason of this is the scarce make up of the link between bowel emptying and general well being.

As for itself, the toilet habit of a person in a done moment of its biological cycle can inform us at least on some peripheral cholinergic mechanisms.

As it happens in all mentally retarded, Down persons show many vegetative functions more troubled, as compared with non mentally retarded individuals. Since I nearly always looked at toilet habits in Downs even during the first consultation, now I own a huge amount of data on this field.

In 1996 I published the first epidemiological survey on toilet habits of 492 Downs as collected during the first consultation. I shall try now to see about how these habits varied after drug therapy.

Materials and method

I have looked into the records of a consecutive non selected series of 548 home-reared and home living Downs, all personally seen between January 1979 and April 1997.

The records of persons having also autism or other PDDs were not looked at. The second illness could have added new variables the weight of which does not actually have a proper evaluation. Of the remaining records, I singled out only those that had toilet habit looked over both at first consultation and at a checkup after starting drug therapy.

From these records I collected:

- sex;

- chromosomal diagnosis;

- age (months) at first consultation;

- age (months) at the last checkup;

- toilet habits at first consultation and at the last checkup.

- length of drug therapies (months).

On these habits I had asked the parents, or the escort and/or the Down subject himself, if he could answer in a precise way.

This information had always its record in very detailed way. I believed it as a useful tool, for example, to understand how the parasympathetic intestinal tone was working.

Among prescribed drugs, although individually tailored, always a benzodiazepine and pyridoxine, often l-glutamine, often carbamazepine, quite often tetrahydrofolates and s-adenosil-l-methionine were prescribed (Cocchi, 1993).

Collected data had statistical evaluation by Chi Square test.

Results.

Only 209 records, referring to 209 Downs, owned prefixed criteria. The Downs presented epidemiological features as reported in Table 1.

The M/F ratio and the distribution of chromosomal diagnoses - after pro rate attribution of the small group of "clinical diagnoses" - lead to maintain this sample as a representative sample.

In restrictive sense, this is surely true at least for the whole population of Italian Downs.

Although grouped according to the prevailing habit - a rough means to describe them in this sample - toilet habits after drug therapy results even improved in a very significant way.


Discussion

This is the second survey on the same topic, when the feature of the first one was a general epidemiological survey (Cocchi, 1996)

As for itself, the way a person empties his bowel in a particular moment of his biological cycle could inform us at least on current working of some peripheral cholinergic mechanisms. In other terms, as for atonic constipation or the spastic one, we can view both as opposite states of intestinal cholinergic functions. We think atonic constipation as a state of reduced cholinergic activity, and spastic constipation exactly as the opposite.

Despite my purpose of having toilets habits checked for every Down I have seen after a drug therapy period, only 209 subjects make up this sample. Here too, the collected data can give us a picture that adds new information on something that the parents are concerned of. As I wrote in my previous paper, literature gives poor support to this topic.

As for the two cases of so diagnosed celiac syndrome, Smila & Kekkonen, 1990, asserted a prevalence of 8 cases out of a thousand alive newborns. In our group of drug treated Downs a very curious thing happened, and I shall refer it as such. The so-called celiac features of toilet habits in two diagnosed Downs disappeared, and a normal diet replaced the gluten free diet.

I hope to come back to this topic, with which I tried to do myself acquainted by making a review of opioids' excess theory, according to Reichelt (Cocchi, 1996). I think the two cases here reported had quite forced diagnoses of celiac syndrome.

Being this sample representative, I found a significant improvement after drug therapy by considering both toilet habits fully analysed (Tab. 2) and the survey done on groups of prevailing habit (tab. 3) As I previously wrote, in order to explain toilet habits in non drug treated Downs, we need to see about many factors, often common to the same age general population.

We must remember the low physical activity, the refusal of eating raw or cooked vegetables and fruit, the need of antibiotic therapies, the so called psychosomatic reactions. All these factors are believed stronger in Downs, with universal consensus for low physical activity and larger use of antibiotics.

On the refusal of the vegetables and fruit intake, as a stress symptom named hyponeophagia, I carried out investigations both in non-treated and in drug treated Downs (Cocchi, 1994; 1995). A lower emotional threshold common to every mentally retarded could determine an increase in psychosomatic reactions, even intestinal ones. We can easily think that the ways of emptying the bowel relate to local cholinergic activity. The last should be low intensity in atonic constipation, and higher intensity in spastic constipation and non-infective diarrhoea.

Drug treatment acts by decreasing susceptibility to upper respiratory tract infections (Cocchi, 1987), by improving motor skills (Cocchi, 1989; Cocchi and Favuto, 1993; 1995), by broadening diet with larger eating of fibres, following more cooked and raw vegetables, and fruit intake (Cocchi, 1995), by raising the emotional threshold because the constant presence of a benzodiazepine among prescribed drugs (Cocchi, 1992).

It is worthy to note that this sample already had about 70% of nearly normal toilet habits from the records taken during the first consultation. In the larger sample of the previous research, which encompassed the current sample too, the same rate was about 50% (Cocchi, 1996).

This appears a contradictory fact but I suppose there should be a plain explanation. Most parents who came back for checkup were those who observed some improvement after 3-4 months of the low doses drug therapy of the starting. So they reached motivation to go on. In this way a group of more easily responders could have been singled out.

There is however a variable that deserves a deeper investigation, and I am referring to how age acts on toilet habits in Downs. Although I did its evaluation in the previous research (Cocchi, 1996), I shall compare drug treated and non treated Downs only by matching same age subjects. For this I planned a third investigation on this topic.

Conclusion

The investigation on toilet habits of 209 Downs, treated by drugs for average 6 years about, showed a significant modification both in punctual and in prevailing habit analysis. Drug therapy favourably acted on various factors (eg. susceptibility to upper respiratory tract infections with need of antibiotics, reduced development of motor skills, reduced diet choice, a low emotional threshold) which all can negatively interfere with bowel emptying.
