Diabetes or hyperglycemia associated with the use of atypical anti-psychotic agents is a subject of growing concern among health care providers and the patients who use the drugs. Although much attention has been relegated to this topic in the mental health literature, there has been little attention devoted to it in the diabetes literature. The purpose of this report is to review the problem of diabetes mellitus associated with atypical anti-psychotic use from an endocrinology perspective. This paper will specifically present (a) a review of the increased prevalence of diabetes in the setting of schizophrenia, (b) a compilation and critical assessment of the existing publications that have documented the association of hyperglycemia and atypical anti-psychotic use, (c) a discussion of the potential mechanisms through which antipsychotics may lead to disturbances in glucose homeostasis, and (d) recommendations for the effective monitoring and treatment of affected patients.

Reactions in leprosy causing nerve function impairment (NFI) are increasingly treated with standardized regimens of corticosteroids, often under field conditions. Safety concerns led to an assessment of adverse events of corticosteroids, based on data of three trials studying prevention of NFI (the TRIPOD study). A multicentre, randomized, double-blind placebo-controlled trial was conducted in leprosy control programmes in Nepal and Bangladesh. Treatment was with prednisolone according to fixed schedules for 16 weeks, starting in one trial with 20 mg/day (prophylactic regimen: total dosage 1.96 g) and in the other two trials with 40 mg/day (therapeutic regimen: total dosage 2.52 g). Minor adverse events were defined as moon face, fungal infections, acne, and gastric pain requiring antacid. Major adverse events were defined as psychosis, peptic ulcer, glaucoma, cataract, diabetes and hypertension. Also, the occurrence of infected plantar, palmar, and corneal ulceration was monitored, together with occurrence of TB. Considering all three trials together, minor adverse events were observed in 130/815 patients (16%). Of these, 51/414 (12%) were in the placebo group and 79/401 (20%) in the prednisolone group. The relative risk for minor adverse events in the prednisolone group was 1.6 (P = 0.004). Adverse events with a significantly increased risk were acne, fungal infections and gastric pain. Major adverse events were observed in 15/815 patients (2%); 7/414 (2%) in the placebo group and 8/401 (2%) in the prednisolone group. No major adverse events had a significantly increased risk in the prednisolone arm of the trials. No cases of TB were observed in 300 patients who could be followed-up for 24 months. Standardized regimens of corticosteroids for both prophylaxis and treatment of reactions and NFI in leprosy under field conditions in developing countries are safe when a standard pre-treatment examination is performed, treatment for minor conditions can be carried out by field staff, referral for specialized medical care is possible, and sufficient follow-up is done during and after treatment.

With the widespread use of atypical antipsychotics over the past several years, adverse metabolic effects have emerged as the most serious medical consequences of pharmacotherapy with some of these agents. Initially, weight gain and obesity were observed (especially with clozapine and olanzapine), but subsequently, type 2 diabetes and dyslipidemia became apparent as well. Further, many reports suggest that sudden and severe (occasionally fatal) diabetes ketoacidosis (DKA) can emerge during treatment with some atypical antipsychotics, even in the absence of adiposity. A marked increase of serum lipids (especially triglycerides) has also been reported, to varying degrees, with different atypicals. This article reviews the data regarding metabolic dysfunction in patients with psychosis (schizophrenia and bipolar disorder). Populations with psychosis have a 2-3-fold higher prevalence of diabetes even before treatment with any antipsychotics, suggesting a possible genetic linkage or comorbidity; this was confirmed with glucose regulation studies in schizophrenia and mania. The induction of type 2 diabetes with atypicals has further increased the prevalence of noninsulin-dependent diabetes from about 6% to 8% to 11% to 15% according to recent studies, and even higher rates of subclinical hyperglycemia. Serious weight gain (eg, 26-29 lbs after 1 year of clozapine or olanzapine treatment) is an important risk factor, but sudden DKA has now been reported in patients with minimal weight gain, suggesting alternative mechanisms, such as insulin resistance, as a direct effect of some atypicals. Psychiatrists can reduce the risk of metabolic disorders in schizophrenia and bipolar disorder by avoiding the use of certain atypicals as first-line treatment in patients with a personal or family history of diabetes, obesity, and hyperlipidemias. Regulatory agencies in some countries have already taken action in this regard.

Physical and mental illnesses commonly occur together. The quality of physical care in institutions for mental health in the Netherlands is not guaranteed. The cases of a 63-year-old woman with a schizoaffective disorder and diabetes mellitus who became delirious after surgery and a 76-year-old suicidal man with a psychotic disorder due to hydrocobalamine deficiency after major heart surgery show that the so-called medical-psychiatric unit, which is a part of the Psychiatric Department of a general hospital, may have several advantages in the treatment of combined physical and mental disorders. Both patients were admitted to such a unit. In this way, the internist of the first patient could continue to treat her and she could be treated with an infusion, urinary catheter and gastric intubation; in addition, laboratory investigations could be performed. The second patient, whose safety required primary attention, could also be treated for his somatic disorders and a delirium could be ruled out. His family was assisted in recovering from their traumatic life experience caused by his suicide attempt.

Thiamine-responsive megaloblastic anemia (TRMA) syndrome is an autosomal recessive disorder characterized by diabetes mellitus (DM), progressive sensorineural deafness, and thiamine-responsive anemia. Mutations in the SLC19A2 gene encoding a high-affinity thiamine transporter protein THTR-1 are responsible for the clinical features associated with TRMA syndrome. We report an African-American female with TRMA-syndrome associated with thyroid disease and retinitis pigmentosa caused by a novel mutation in the SLC19A2 gene. The patient presented at 12 months of age with paroxysmal atrial tachycardia and hepatosplenomegaly. One month later, she developed DM requiring intermittent insulin therapy. At 2-1/2 years of age, profound sensorineural hearing loss was discovered. By 4 years of age, daily insulin therapy (0.5 U/kg/day) was instituted and her insulin requirement gradually increased to 1.0 U/kg/day by 9 years of age. She developed optic atrophy, retinitis pigmentosa, and visual impairment by 12 years of age with severe restriction of peripheral vision by 16 years. At age 19, a thiamine-responsive normocytic anemia was discovered. She was diagnosed with autoimmune thyroiditis at 20 years and she experienced a psychotic episode associated with a mood disorder at age 21. With oral thiamine therapy, her insulin requirement decreased by 30% over a 20 month period. Molecular analysis revealed that the patient is homozygous for a missense mutation (C152T) in exon 1 of the SLC19A2 gene.

There have been reports in the psychiatric literature of the association of glucose dysregulation and diabetes mellitus with the use of atypical and typical (conventional) antipsychotics. We present a series of 4 additional cases in which psychotic disorders (DSM-IV) were treated with atypical antipsychotics, and patients subsequently developed glucose dysregulation or diabetes mellitus. The implications of these findings are discussed.

BACKGROUND: Physicians in the United States write approximately 10 million new prescriptions for oral corticosteroids each year. Common side effects of corticosteroids include weight gain, osteoporosis, and diabetes mellitus. This article reviews the available literature on psychiatric and cognitive changes during corticosteroid therapy. METHOD: A search of the MEDLINE and psycINFO databases was conducted to find clinically relevant articles on psychiatric and cognitive side effects with corticosteroids using search terms including corticosteroid, prednisone, mania, depression, psychosis, mood, memory, and cognition. RESULTS: Symptoms of hypomania, mania, depression, and psychosis occur during corticosteroid therapy as do cognitive changes, particularly deficits in verbal or declarative memory. Psychiatric symptoms appear to be dose-dependent and generally occur during the first few weeks of therapy. Patients who must remain on corticosteroids may benefit from pharmacotherapeutic approaches, such as lithium and the new antipsychotic medications. CONCLUSION: Mood and cognitive changes with corticosteroids appear to be common but generally mild and reversible side effects. More studies are needed to determine effective treatment for steroid-induced psychiatric disorders.

Psychiatric manifestations are frequently associated with pernicious anemia including depression, mania, psychosis, dementia. We report a case of a patient with vitamin B12 deficiency, who has presented severe depression with delusion and Capgras' syndrome, delusion with lability of mood and hypomania successively, during a period of two Months. Case report - Mme V., a 64-Year-old woman, was admitted to the hospital because of confusion. She had no history of psychiatric problems. She had history of diabetes, hypertension and femoral prosthesis. The red blood count revealed a normocytosis with anemia (hemoglobin=11,4 g/dl). At admission she was uncooperative, disoriented in time and presented memory and attention impairment and sleep disorders. She seemed sad and older than her real age. Facial expression and spontaneous movements were reduced, her speech and movements were very slow. She had depressed mood, guilt complex, incurability and devaluation impressions. She had a Capgras' syndrome and delusion of persecution. Her neurologic examination, cerebral scanner and EEG were postponed because of uncooperation. Further investigations confirmed anemia (hemoglobin=11,4 g/dl) and revealed vitamin B12 deficiency (52 pmol/l) and normal folate level. Antibodies to parietal cells were positive in the serum and antibodies to intrinsic factor were negative. An iron deficiency was associated (serum iron=7 micromol/l; serum ferritin concentration=24 mg/l; serum transferrin concentration=3,16 g/l). This association explained normocytocis anemia. Thyroid function, hepatic and renal tests, glycemia, TP, TCA, VS, VDRL-TPHA were normal. Vitamin B12 replacement therapy was started with hydroxycobalamin 1 000 ng/day im for 10 days and iron replacement therapy. Her mental state improved dramatically within a few days. After one week of treatment the only remaining symptoms were lability of mood, delusion of persecution, Capgras' syndrome but disappeared totally 9 days after the beginning of the treatment. A neurologic examination was possible because of cooperation. All the tendon reflexes of inferior members were absent. The plantars were in flexion and there was a left inferior member hypoesthesia. The cerebral scan and EEG were normal. Fundic biopsy, realized by fibroscopy, revealed fundic atrophia and intestinal metaplasia compatible with Biermers' disease. The iron deficiency exploration concluded diet deficiency. Mme V. appeared euphoric, her speech was very rapid with play on words and overactivity. This hypomania state totally disappeared 3 days after. Six Months after her hospitalisation, she presented an hypothyroidism (TSH=3,780; T3=1,35; T4=1,08). A thyroid hormones replacement was started and she continued to receive Monthly B12 replacement. Discussion - This case report illustrates psychiatric manifestations of Biermers' disease. The clinical arguments in favour are: white woman, more than 60 Years old, no history of psychiatric problems, atypical symptoms (confusional state with psychiatric symptoms), fluctuation of symptoms (severe depression with confusional state, delusion of persecution and Capgras' syndrome; delusion with lability of mood and hypomania), dramatic improvement after 9 days of vitamin B12 replacement therapy. The biological arguments are: anemia, vitamin B12 deficiency, normal folate level, atrophia and fundic metaplasia, positive antibodies to parietal cells in the serum, association between Biermers' disease and autoimmune disease (Haschimoto thyroidite). Psychiatric manifestations can occur in the presence of low serum B12 levels but in the absence of the other well recognized neurological and haematological abnormalities of pernicious anemia. Mental or psychological changes may precede haematological signs by Months or Years. They can be the initial symptoms or the only ones. Verbank et al. described the case of a patient with vitamin B12 deficiency in whom hypomania, paranoia and depression had been successively presented during a period of 5 Years before anemia have been developed. The case of Mme V. is similar in the succession of severe depression with delusion of persecution and Capgras' syndrome, delusion with lability of mood and hypomania, during a period of two Months. This report seems to be the first one of a sequence of several psychiatric states with pernicious anemia during a period of two Months with normocytosis anemia. To illustrate this illness we reviewed the literature regarding psychopathology associated with B12 deficiency. The most common psychiatric symptoms were depression, mania, psychotic symptoms, cognitive impairment and obsessive compulsive disorder. The neuropsychiatric severity by vitamin B12 deficiency and the therapeutic efficacy depends on the duration of signs and symptoms. Conclusion - We recommend consideration of B12 deficiency and serum B12 determinations in all the patients with organic mental disorders, atypical psychiatric symptoms and fluctuation of symptomatology. B12 levels should be evaluated with treatment resistant depressive disorders, dementia, psychosis or risk factors for malnutrition such as alcoholism or advancing age associated with neurological symptoms, anemia, malabsorption, gastrointestinal surgery, parasite infestation or strict vegetarian diet. In first intention, B12 deficiency should be researched by serum B12 determination (normal 200-950 pg/ml). Studies of methylmalonic acid and homocysteine showed that they are very sensitive functional indicators of cobalamin status especially when other evidence of cobalamin (B12) deficiency was equivocal. Measurement of methylmalonic acid (normal 73-271 nmol/l) and homocysteine (normal 5,4-13,9 micromol/l) should not replace the measurement of serum cobalamin.

Schizophrenia is a multifactorial disease with complex interactions between a genetic liability, possible perinatal complications and exposure to later environmental risk factors in childhood. Maternal influenza infection, wartime-famine-related denutrition and maternal depression or exposure to repeated stress in pregnancy may have a deleterious effect on brain development and neuronal migration. Obstetrical complications which are significantly associated with schizophrenia are bleeding, diabetes, prematurity, fetal growth retardation, Rhesus incompatibility, preeclampsia and congenital malformations. Subjects with onset of schizophrenia before age 22 had more often a history of acute fetal distress (abnormal presentation at birth and complicated cesarean delivery). Obstetrical complications may have a direct negative impact on fetal brain development or may be on the causal pathway between prepartum maternal depression or psychosis, exposure to stress and impaired relation between mother and child consecutive to postnatal depression.

Schizophrenia is a psychiatric disease affecting around 1% of the population, the negative signs of which are correlated with inactivity of the prefrontal dorsolateral cortex, while an increased, more deeply localized, activity in the mesolimbic pathway may explain the positive signs. Several events occurring during pregnancy are likely to be involved in its genesis: hormonal supplementation by diethylstilbestrol, severe maternal denutrition, exposure to influenza virus, repeated psychological stress. From multicentric studies and meta-analyses in the psychiatric literature, the risk of schizophrenia appears to be multiplied by two if pregnancy is complicated, mainly by diabetes, Rhesus incompatibility, bleeding, preeclampsia, premature rupture of membranes and preterm birth. When delivery is linked to an abnormal presentation or happens via a caesarean birth for acute foetal distress, the time when the first signs of psychosis appear seems to be earlier in adolescence or in early adulthood. Cerebral imaging of schizophrenic patients shows ventriculomegaly and gray matter reduction, mainly in hippocampal volumes and in the dorsolateral prefrontal cortex. Similar alterations in the neuronal pathways have been experimentally reproduced in rats after repeated prenatal stress and perinatal hypoxia. A region on the distal portion of chromosome 1 has shown evidence for linkage to schizophrenia. Therefore, a two factor model seems to be able to explain the onset of schizophrenia in which obstetrical complications may interact with a genetic liability and in which the consequences of hypoxic events may lie on a continuum ranging from cerebral palsy in some children to subtle cognitive and behavioural disturbances in others.
