The authors determined in 1984 by radioimmunoassay (INEP kit) the serum prolactin concentration in 76 multiple sclerosis patients (33 males and 34 females) aged from 21 to 53 years, with disease duration from 2 to 30 years. The control group comprised 110 healthy subjects. Normal prolactin values were 150-750 mIU/ml in females and 150-500 mIU/ml in males. In about one-third of the patients raised prolactin level was found which failed to correlate with the age of the patients and with increased beta-endorphin level in them. The authors suppose that hyperprolactinaemia may be of importance in certain clinical signs of multiple sclerosis. Further investigations on prolactin are conducted with reference to the circadian rhythm of prolactin secretion and dynamic tests.

The term "Schilder's disease" has been used to describe conditions as disparate as adrenoleukodystrophy, myelinoclastic diffuse sclerosis, and postinfectious and postvaccinal encephalomyelitis. The eponymic designation should be reserved for instances of myelinoclastic diffuse sclerosis that correspond to the case described by Schilder in 1912. The diagnosis cannot be made unless adrenoleukodystrophy has been ruled out by analysis of the long-chain fatty acids of plasma cholesterol esters. Schilder's myelinoclastic diffuse sclerosis, a variant of multiple sclerosis, is a very rare disease that occurs in children and adults of both sexes and appears to respond to vigorous treatment with corticosteroids and/or corticotropin. A case of this disease is reported and the recent literature of cases that have been called Schilder's disease is reviewed.

This article has reviewed some of the principles of the immune basis of multiple sclerosis and one potential therapy: cyclophosphamide and corticotropin. Although some of the studies with this combination present encouraging findings, these must be carefully evaluated. This approach is still experimental and the long-term effects of therapy are still to be evaluated. The neuroscience nurse has an important place in this research. Not only should the nurse be a critical consumer of the research investigating these protocols, but she must also use unique nursing skills to assist the patient while undergoing the therapy.

Megavoltage CNS irradiation was given to 20 patients with clinically definite multiple sclerosis (MS) to determine if de novo CNS IgG synthesis could be eradicated. In all five patients given 1,200 rads, a transient reduction in the de novo CNS IgG synthesis rate was noted. In ten patients given 1,800 rads, the following occurred: a reduction in synthesis rate in three patients, a reduction followed by enhancement in two, only enhancement in four, and no change in one. In all five additional patients, a therapy of adrenocorticotropic hormone (ACTH) followed by prednisone in combination with 1,800 rads produced greater and more persistent decreases in CNS IgG synthesis, but did not block the enhancement effect. Only two of 19 patients who had abnormal CNS IgG synthesis rates had reductions to normal; no patients showed changes in the number or pattern CSF IgG oligoclones. Hence, no treatment eradicated de novo CNS IgG synthesis. A persistent decrease in CSF leukocytes occurred in all 20 patients due to the reduction of small lymphocytes (not dose related). The blood-brain-barrier to albumin concentration was transiently damaged in 11 of 15 patients given irradiation, but when patients were premedicated with ACTH/prednisone therapy, no damage was found. None of the patients demonstrated neurological improvement, change in the activity of their disease, or persistent adverse effects.

The proliferative response of peripheral blood T cells to autologous non-T cells, a reaction called the autologous mixed lymphocyte reaction (MLR), was significantly increased in 17 patients with active multiple sclerosis (MS) compared to age- and sex-matched individuals with other neurological diseases (OND). Following a 10-day course of intravenous adrenocorticotropic hormone (ACTH) therapy the values were reduced to control levels. No differences were noted between MS patients and controls in their response to alloantigens. The increased autologous MLR in patients with active MS appeared to result from an increased stimulatory capacity of non-T cells rather than from an intrinsically greater T cell proliferative potential. ACTH appeared to induce a change in the populations of circulating non-T cells such that these cells had a decreased stimulatory capacity in both autologous and allogeneic MLR. The decrease in stimulatory capacity in autologous MLR was, however, significantly greater than the decrease in allogeneic stimulatory capacity, suggesting a functional decrease of specific non-T cell-enriched subpopulations. No significant changes in the numbers of myeloperoxidase-positive (MP+) cells were noted in the blood of MS patients before and after ACTH therapy. Since the autologous MLR results in generation of cells that regulate immune responsiveness, the changes noted provide additional evidence for abnormal immune regulation in MS.

We measured the total daily urinary cortisol produced by each of 8 patients with multiple sclerosis during intravenous therapy with adrenocorticotropic hormone (ACTH). Results indicated marked daily variation from patient to patient as well as in the same patient, suggesting that ACTH infusions do not result in reliable, consistent, high-level production of cortisol. We attempted to express the quantity of cortisol produced as an equivalent amount or oral prednisone. This comparison is difficult to make; but, given certain assumptions, the figures suggest that 40 U or 80 U ACTH infusions do not elicit the quantities of steroid generally considered to be indicated for the therapy of major allergic, autoimmune, or neoplastic diseases.

9 patients with bladder disorder secondary to multiple sclerosis (MS) were treated by dorsal column stimulation (DCS). Detailed urodynamic tests were performed and leg blood flow was assessed on repeated occasions. Cerebrospinal fluid (CSF) met-enkephalin levels were estimated before and during DCS. The chief effect of DCS was improved urinary flow associated with reduced sphincter tone and lessened detrusor instability maximal at the 6th or 7th day of continuous stimulation. Considerable fluctuation in leg blood flow occurred unrelated to activation of the stimulator. No obvious change in CSF met-enkephalin levels took place, but it is suspected that the mode of action of DCS in via certain peptide hormones.

Upper airway obstruction resulting from a paratracheal abscess developed insidiously and led to the death of a 43-year-old woman with multiple sclerosis. Repeated nasogastric intubation, required by an exacerbation of bulbar symptoms, may have initiated this unusual infection. Corticotropin and corticosteroid therapy may have impaired immunologic competence and masked fever and other symptoms of inflammation. Hoarseness and inspiratory stridor should not be attributed to laryngeal paresis in patients with multiple sclerosis unless other causes of airway obstruction have been excluded by appropriate diagnostic studies.

Clinical observations and animal studies suggest that the hypothalamo-pituitary-adrenal (HPA) axis plays a role in the susceptibility to and the recovery from multiple sclerosis (MS). Since the HPA-axis is under the control of corticotropin-releasing hormone (CRH) neurons of the hypothalamus, we determined 2 parameters for activation of the CRH neurons in the hypothalamic paraventricular nucleus (PVN) in MS patients. Since the HPA-axis is more activated in MS, we expected an increased activity of CRH neurons. We also expected to see an age-related increase in CRH activity, because of the possible role of the HPA-axis in the age-related decrease in susceptibility to MS. The number of CRH cell profiles and the proportion of CRH neurons co-expressing vasopressin were used as parameters for activity. CRH cell population became more activated both in control and MS patients, from 40 years of age onwards, when the prevalence of MS starts to decrease in the population. The CRH neurons showed a significantly higher level of activation in MS patients than in controls, as appeared from the 3-fold increase in CRH cell number and the 4.5-fold increase in cells co-expressing CRH and vasopressin (AVP).

Observations in experimental allergic encephalomyelitis (EAE), a model for multiple sclerosis (MS), have indicated that a low activity of the hypothalamo-pituitary-adrenal (HPA) system is accompanied by a high susceptibility for EAE in rat strains and that elevated corticosteroid levels are necessary for spontaneous recovery from EAE. The HPA axis activity is regulated by both corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP). Both types of neurons are localized in the paraventricular nucleus (PVN) of the hypothalamus. We determined the number of immunocytochemically identified CRH-immunoreactive (CRH-IR) and AVP-immunoreactive (AVP-IR) neurons in the PVN of the human hypothalamus of 8 MS patients, aged 34-63 years, and 8 age-matched control subjects without any primary neurological or psychiatric disorders, aged 30-59 years. In addition, the number of oxytocin (OXT) immunoreactive (OXT-IR) neurons was determined, since these neurons innervate brain stem nuclei and might thus be related to autonomic disturbances in MS. In MS the staining intensity for AVP was clearly lower and for OXT slightly lower. For CRH, the staining intensity was similar in both groups, and, moreover, in MS patients the number of CRH-IR cells in the PVN was found to be about 2.4 times higher than that in the control group. The number of OXT-IR or AVP-IR cells in the PVN of MS patients was not significantly different from that of the control group. Our results point to an activation of the neuroendocrine HPA axis which may be compatible with the idea that the HPA axis is involved in recovery from MS.(ABSTRACT TRUNCATED AT 250 WORDS)
