Lower Estimated Glomerular Filtration Rates in Patients On Long Term Lithium; a Comparative Study and a Meta-analysis of Literature

Abstract

Background: Several studies have shown that long-term lithium use is associated with a subtle decline in estimated glomerular filtration rate. This study compared mean estimated glomerular filtration rates (eGFR) in patients on long term lithium, against matched controls. Methods: Patients with bipolar affective disorder, who are on lithium (for at least a year), were compared against controls that were matched (1:1) for age, gender and presence or absence of diabetes or hypertension. The eGFR was calculated from creatinine values according to the 'modification of diet in renal disease study' (MDRD) formula and was compared between cases and controls. A meta-analysis was performed to compare our findings with similar studies in literature. Results: Forty seven patients met the inclusion criteria. They were matched with 47 controls. The eGFR values of lithium users were significantly lower (p = 0.04) compared to controls. This difference persisted between the subgroup of lithium users without comorbidities (diabetes and hypertension) and their controls but disappeared for lithium users with comorbidities and their controls. Nonetheless, lithium users had lower eGFR values in both subgroups. A meta-analysis of 9 studies showed a significant lowering in the glomerular filtration rate in lithium users compared to controls [mean difference −10.3 ml/min (95% confidence interval: -15.13 to −5.55, p < 0.0001)]. Conclusions: Lithium causes a subtle decline in glomerular filtration rate; renal function needs to be monitored in patients on lithium treatment.

Psychiatric and physical outcomes of long-term use of lithium in older adults with bipolar disorder and major depressive disorder: A cross-sectional multicenter study

“…However, numerous studies have reported a deterioration of renal function in older adults with longer use of lithium therapy (36,(62)(63)(64)(65). The annual decrease of GFR is estimated at 2.3 ml/min/1.73m 2 in this population (66).…”

Hypertensive bipolar: chronic lithium toxicity in patients taking ACE inhibitor

“…Apart from advanced age, duration of lithium treatment is an added risk factor for reduced glomerular filtration rate (GFR) and the subsequent deterioration of renal function 10. Studies showed that patients on long-term lithium had significantly lower GFR values11 and renal failure tends to ‘appear after decades of treatment and gradually progresses irrespective of lithium continuation’ 12. Nephrogenic diabetes insipidus, tubulointerstitial nephritis and nephrotic syndrome are among the manifestations of lithium nephrotoxicity.…”

“…раздел 2.1). Другие факторы риска, которые необходимо учитывать в данной группе пациентов, -это эректильная дисфункция и гиперпролактинемия, которая носит вторичный характер при антипсихотической фармакотерапии (83,84), а также хроническое поражение почек как побочное действие литиумной профилактики (85). Эти независимые факторы риска ССЗ являются следствием лечения, назначаемого по поводу психоза, что может значительно повышать сердечно-сосудистый риск.…”
