Retinal depression, a newly observed sign, has been observed as an abnormality in the reflection from the internal limiting lamina produced by depression of the inner surface of the retina after a small retinal infarct. These depressions were first observed in 16 patients with sickling hemoglobinopathies. Additionally, I examined a patient with systemic hypertension, a patient with retinal arteriolitis, and a patient with juvenile onset diabetes mellitus who also had retinal depression.

Flow cytometry with monoclonal antibody Leu-7 (CD57), Leu-11 (CD56) and Leu-19 (CD56) were used to study the content of different subpopulations of natural killer cells (NK-cells) in the blood of type I diabetes mellitus patients before and after insulin treatment and in healthy people. After a course of insulin therapy most patients showed restoration of the total cell number with antigens on their surface characteristic of NK-cells, especially CD56, that indicates the essential role of hypoinsulin in the depression of the NK-system. At the same time a small group of patients was distinguished who did not show such normalization. This may indicate participation of other mechanisms in the formation of natural immunity failure, in particular, the genetic.

The objective of this study was to evaluate the polymorphonuclear leukocyte (PMN) function in a poorly controlled adult insulin-dependent diabetic patient (IDDM) with severe recurrent periodontitis, while describing the microbiological and clinical findings. Chemotaxis, superoxide production, and phagocytosis and killing of Porphyromonas (Bacteroides) gingivalis by the IDDM PMN were evaluated 1 week before treatment relative to a healthy, matched control. These analyses revealed a significant (P less than .05) depression in the number of IDDM PMNs migrating along an FMLP gradient (Boyden chamber assay). In addition, a significant (P less than .05) enhancement of IDDM PMN superoxide production in response to opsonized zymosan (cytochrome C reduction) was observed. Phagocytosis and killing (fluorochrome phagocytosis assay) by IDDM PMN of two P. gingivalis strains was also impaired significantly (P less than .05). The subgingival microflora contained significant levels of P. gingivalis, Actinobacillus actinomycetemcomitans, Eikenella corrodens, and Peptostreptococcus micros. Periodontal treatment consisted of extraction of hopeless teeth, scaling and root planing and 3 weeks of Augmentin therapy. The antibiotic therapy resulted in unrecoverable numbers of the putative pathogens and a reduction in both gingival inflammation and disease progression. The IDDM healing response to previous surgical treatment and extractions was poor, presumably due to a marked thrombocytopenia (91 x 10(3) platelets/mm3).

Monoclonal antibodies were used to characterize peripheral T-lymphocyte subpopulations in 23 patients with type I diabetes mellitus. Initial measurements were made at diagnosis and in 10 of the patients further studies were carried out at 1, 3 and 6 months. T-cell subsets were also measured in 16 patients with type II diabetes, in 16 patients with various autoimmune diseases and in 17 healthy control subjects. At diagnosis, the type I diabetic patients showed a significant decrease in the percentage of cytotoxic/suppressor cells. Both total T-cells and helper/inducer cells were normal. However, when the helper/inducer population was analyzed in the context of islet cell antibodies (ICAs), it was found that those patients possessing ICAs had significantly higher proportions of helper/inducer cells than those lacking them. A significant inverse correlation was seen between the proportions of total T-cells and NK/K cells. At 1 month, the proportions of cytotoxic/suppressor cells returned to normal, whilst the helper/inducer cells showed a transient depression. By 6 months, the only change seen was a significant increase in the percentage total t-cells. No relationship was found between T-cell subset perturbation and metabolic control, as assessed by measurement of hemoglobin A1 (HbA1). The type II diabetic patients showed a significant increase in the percentage of total T cells. The autoimmune patients also showed a significant increase in the proportions of total T-cells; this appeared to reflect an increase in the helper/inducer subset. In the autoimmune patients these findings occurred in conjunction with significant decreases in the absolute numbers of each T-cell subset. It is surmised that, in some cases of type I diabetes, alterations in immune homeostasis may permit autoimmune processes, which lead to cell damage at the onset of diabetes.

The incidence and prevalence of depression in diabetic patients in the United Kingdom is unknown. Since depression may influence blood glucose control which in turn may be related to the development of diabetic complications, it is important to estimate its prevalence in diabetic patients. The prevalence of depression was investigated in a group of Caucasian and West Indian, insulin-(IDDM) and non-insulin-dependent (NIDDM) adult diabetics and a non-diabetic comparison group. Prevalence of depression was 8.5% for both groups and a further 19.2% and 14.6%, respectively, had borderline depression. Presence of depression was unrelated to sex, ethnic group, duration or type (IDDM or NIDDM) of diabetes and social class but significantly related to type of accommodation, marital status, and amount of social contact. A higher percentage of diabetics with psychiatric symptoms had one or more current complications compared to 'normal' diabetics. Diabetics suffer from a similar amount of depression to non-diabetics, but psychiatric symptoms may be related to the frequency of diabetic complications.

The clinical course of 24 patients with insulin-requiring diabetes mellitus who had received total parenteral nutrition (TPN) was retrospectively analyzed. Routine nutritional assessment disclosed significant depression of anthropometric indices and secretory protein levels in patients with chronic renal failure complicating juvenile onset diabetes mellitus (JODM). Biochemical complications including hypo- or hyperglycemia were significantly more frequent (p less than 0.001) in JODM than in maturity-onset diabetes and found to a lesser degree in patients with renal failure. The catheter infection rate was substantially higher (17%) than usually encountered in TPN therapy. Positive nitrogen balance was achieved in the majority of patients with an average 84% and 92% of estimated protein and caloric requirements being provided. Close monitoring and a protocol of infusion plus supplemental subcutaneous regular insulin was useful in providing adequate TPN safely to these high-risk patients.

Effects of epinephrine (Epi) infusion on the absorption of subcutaneously injected 125I-labeled soluble human insulin (10 U) from the thigh or the abdomen were studied in 16 healthy subjects and from the thigh in 10 insulin-dependent diabetic (IDDM) patients. Epi was infused at 0.3 (high dose) or 0.1 (low dose; healthy subjects) nmol.kg-1.min-1 i.v., resulting in arterial plasma Epi levels of approximately 6 and 2 nM, respectively. Saline was infused on a control day. Insulin absorption was measured as disappearance of radioactivity from the injection site and as appearance of plasma immunoreactive insulin (IRI). Adipose tissue blood flow was measured with the 133Xe clearance technique. First-order disappearance rate constants of 125I from the thigh depot decreased approximately 40-50% during the high dose of Epi compared with control (P less than .001). The corresponding decrease from the abdominal depot was approximately 40% (P less than .001), whereas no significant change was found during the low Epi dose. IRI fell compared with control in all groups at the high Epi dose. The Epi-induced depression of insulin absorption occurred despite unaltered or even slightly increased subcutaneous blood flow. The results indicate that circulating Epi at levels seen during moderate physical stress depresses the absorption of soluble insulin from subcutaneous injection sites to an extent that might be important for glycemic control in IDDM patients. Furthermore, dissociation is found between changes in insulin absorption and subcutaneous blood flow during Epi infusion, suggesting that factors other than blood flow may also influence the absorption of subcutaneously injected insulin.

Non-insulin dependent diabetes in older adults is associated with elevated depression and a greater decline in certain aspects of cognitive functioning than is found with normal aging. This study sought to determine whether diabetics report more memory complaints in carrying out their daily activities, and if memory self-assessments are reflective of performance on laboratory tasks. Middle-aged (55-64 years) and old (65-74 years) diabetics and non-diabetic control subjects were studied. Results showed that both diabetes and increased age were associated with poorer performance on some cognitive tests as well as with more self-reported memory problems. When depression levels were statistically controlled, the diabetes variable was no longer a significant predictor of memory complaints. The usefulness of self-assessments as an adjunct to more objective cognitive test measures was discussed.

We have examined the frequency of three phenotypic characteristics of the syndrome of spontaneous diabetes (overt IDDM, lymphocytic infiltration of the pancreas, and depression of T lymphocytes) in the offspring of crosses between IDDM BB rats and rats of strains with the same and different RT1 genotypes. On the basis of these observations we propose that there are at least three components of the diabetic syndrome in the rat: (1) a requirement for the RT1u haplotype from the BB strain or a gene in close linkage with the gene coding for this haplotype, (2) a susceptibility for development of insular, periductular, or intraacinar lymphocytic infiltration in the pancreas, and (3) a susceptibility to depression of T lymphocytes. Interactions between these components as well as with other genetic and environmental factors contribute to the full expression of the syndrome.

The association of juvenile diabetes mellitus (DM), diabetes insipidus (DI), optic atrophy (OA) and sensorineural deafness (D) is known as DIDMOAD or Wolfram syndrome. Aside from these four cardinal features, a wide variety of abnormalities of the nervous system, urinary tract and endocrine glands have been described in this syndrome. In this report, the clinical features of six patients with DIDMOAD syndrome are presented. All six patients had DM. Five of the six patients had DI, five OA and five displayed abnormal audiogram findings. In addition, two had goiter, two delayed puberty, one seizure and one mental retardation with depression attacks. Urinary tract dilatation was recorded in five patients. Four patients developed typical complications of DM. One of them had overt nephropathy and arthropathy despite the short duration of DM. In addition, this patient had diabetic retinopathy, which is considered to be rare in this syndrome.
