Lithium is a well-known treatment for patients with mood disorders. Intoxication by lithium may be lethal particularly in elderly due to altered pharmacokinetics, renal impairment or multiple drug use. We presented a 74-year-old female patient who had been stabile with lithium carbonate 600 mg/day for 5 years and developed lithium intoxication after bronchiolitis. She presented with altered mental status. The neurological signs resolved slowly after lithium and moxifloxacin were stopped immediately and fluid resuscitation administered. Considering possible drug interactions on elderly patients receiving lithium is essential.

Because adenine is effective for managing cases of radiation-induced and drug-induced leukopenia, it may be effective in cases of antipsychotic-induced leukopenia and neutropenia. Here, we report our experience with patients with leukopenia and neutropenia caused by an antipsychotic overdose or discontinuation of lithium carbonate, in whom adenine administration ameliorated the white blood cell and neutrophil counts. The progress of patients suggests that adenine is effective in cases of leukopenia and neutropenia associated with lithium carbonate discontinuation and an antipsychotic overdose.

A 59-year-old woman was admitted to our hospital with polydipsia and general weakness. She had a 30-year history of bipolar disorder and was being treated with risperidone (4 mg/day) and lithium carbonate (1,200 mg/day). During her time in hospital, her urine output and serum osmolality increased, and her urine osmolality decreased. She was found to have myoglobulinuria, an elevated creatine kinase level, and abnormal renal function. Based on these findings, the patient was diagnosed with diabetes insipidus and rhabdomyolysis secondary to lithium therapy. After fluid therapy and the withdrawal of lithium, her clinical symptoms improved significantly. Her urine volume decreased gradually after treatment with amiloride. The effects of lithium on the muscle system are unknown. Hyperosmolarity caused by lithium-induced diabetes insipidus is considered a contributing factor in rhabdomyolysis.

OBJECTIVE: This study sought to identify candidate genes related to the clinical effects of several mood stabilizers through gene expression profiles using microarrays and real time RT-PCR. METHOD: Rats were treated with lithium carbonate, valproate, or clozapine for 10 days. Total RNA was extracted from the rat brains and used for microarray analysis. Of 54 genes showing more than 1.5-fold changes induced by all three mood stabilizers, seven genes were selected, and drug-induced changes in gene expression were confirmed by real time RT-PCR. In addition, genotype distribution of the GRIK2 gene was compared between 181 patients with bipolar disorder and 350 normal controls. RESULTS: Of the seven candidate genes, GRIK2 and PRKAR were confirmed as being downregulated by lithium and valproate. However, none of the genes was affected by all three drugs. The allele and genotype distribution in two SNPs of GRIK2 did not differ between the patient and control groups. CONCLUSIONS: Although this study demonstrated overall negative results, the present findings will be used in future studies for establishing various mechanisms of mood stabilizers.

To investigate whether lithium carbonate, propranolol or chloroquine aggravate psoriasis through influencing cytokines of the psoriatic cytokine network, HaCaT keratinocytes were stimulated with TNF-a after treatment with these drugs. Protein secretion of a set of multiple different cytokines and growth factors in culture supernatants were measured by using a cytokine antibody array technology. Expression of IL-8 and IL-6 mRNA was determined by real-time PCR. In culture supernatants of TNF-alpha-stimulated HaCaT cells, production of IL-6 and TNF-alpha could be enhanced by lithium carbonate; production of IL-6 and a panel of cytokines and growth factors could be enhanced by propranolol hydrochloride; and IL-6 was up-regulated by chloroquine diphosphate as well. Real-time PCR analysis showed a significantly dose-dependent increase of IL-8 and IL-6 mRNA expression in HaCaT cells stimulated with TNF-a as compared to cells without TNF-alpha-stimulation, the mRNA expression of IL-8 was higher than that of IL-6 with the same concentration of TNF-alpha (P < 0.01). Compared with HaCaT cells cultured with medium alone, propranolol hydrochloride at the concentration of 1 x 10(-6) mol x L(-1) could stimulate HaCaT cells to express higher level of IL-6 mRNA (P < 0.05). The drugs investigated show a modulatory effect on certain cytokines and growth factors which are able to modulate inflammatory type of immune reaction present in psoriatic lesions.

BACKGROUND: Thiazides have been used in nephrogenic diabetes insipidus (NDI) patients to decrease urine volume, but the mechanism of antidiuretic effect is not known yet. Recently, it has been demonstrated that abundance of aquaporin-2 (AQP2) was decreased in lithium induced NDI. We performed this study to investigate the effect of hydrochlorothiazide (HCTZ) in lithium induced NDI rats and the change of AQP2 expression. METHODS: NDI was induced in 7 male Spraque- Dawley rats by feeding lithium carbonate containing rat chow (40 mmol/kg) for 5 weeks. 4 rats were control group. HCTZ 3.75 mg/day (n=3 among lithium treated; Li+TZ) or vehicle (n=4 among lithium treated and control; Li and Control, respectively) was infused to the rats through osmotic minipump for the last 7 days. Urine volume and urine osmolality were measured. Kidneys were processed for immunohistochemistry and immunoblotting using antibody to AQP2. RESULTS: Li+TZ showed decreased urine volume (46+/-11 mL/day for Li+TZ vs. 127+/-1 mL/day for Li, p<0.05) and higher urine osmolality (557+/-139 mmol/kgH2O for Li+TZ vs. 207+/-9 mmol/kgH2O for Li, p<0.05) comparing to Li. In semi-quantitative immunoblotting using whole kidney homogenate, Li+TZ showed increase in AQP2 expression comparing to Li (39+/-2% for Li+TZ vs. 20+/-9% for Li, p<0.05, % of normal controls). In immunohistochemistry, AQP2 expression in cortex was markedly decreased after lithium treatment. But, AQP2 expression was slightly increased after HCTZ treatment. CONCLUSION: HCTZ treatment partially increased urine concentrating ability and AQP2 expression in rats with lithium induced NDI. We concluded that partial improvement in urine concentrating ability might be associated with upregulation of AQP2.

Distal Renal tubular acidosis is characterized by tubular dysfunction with a decrease in net H+-secretion in the collecting tubules regardless of normal glomerular filtration rate. It classified into primary and secondary form. The causes of secondary form could be many drugs such as amphotericin B, toluene, lithium carbonate, ifosfamide, but paraquat has not been reported. The mechanism of renal damage by paraquat has not be fully comprehensive but it is thought that paraquat causes damage to renal proximal tubules and clinically induces acute tubular necrosis. Our case demonstrated that immunohistochemical staining of renal biopsy specimen with anti H+-ATPase antibody showed absence of proton pump in collecting duct. Thus a case of distal renal tubular acidosis in association with paraquat intoxication is reported with a review of literatures.

The lithium is widely employed as a psychotropic agent, specially in manic illness. Lithium nephrotoxicity can be divided into three main categories: nephrogenic diabetes insipidus, acute intoxication, chronic nephropathy including interstitial nephropathy and glomerulopathy manifested as nephrotic syndrome. But, nephrotic syndrome induced by lithium is very rare. We reported a nephrotic syndrome induced by lithium in a 27-year-old woman who was taking lithium carbonate for 11 years due to bipolar disorder. Renal biopsy showed membranous nephropathy. After withdrawal of lithium, clinical symptoms and proteinuria significantly improved.

The authors report one-case of hyperthyroidism that occurred in a 56-year-old woman with bipolar disorder after 3 years of chronic lithium treatment. The high level in thyroid fuction test returned to normal after discontinuation of lithium. This case is shows that lithium-induced hyperthyroidism can be reversible.
