OBJECTIVE
To reach a European consensus on the definition and characterization of the main organ-specific extraglandular manifestations in primary SS.
METHODS
The EULAR-SS Task Force Group steering committee agreed to approach SS-related systemic involvement according to the EULAR SS Disease Activity Index (ESSDAI) classification and proposed the preparation of four separate manuscripts: articular, cutaneous, pulmonary and renal ESSDAI involvement; muscular, peripheral nervous system, CNS and haematological ESSDAI involvement; organs not included in the ESSDAI classification; and lymphoproliferative disease. Currently available evidence was obtained by a systematic literature review focused on SS-related systemic features.
RESULTS
The following information was summarized for articular, cutaneous, pulmonary and renal involvement: a clear, consensual definition of the clinical feature, a brief epidemiological description including an estimate of the prevalence reported in the main clinical series and a brief list of the key clinical and diagnostic features that could help physicians clearly identify these features. Unfortunately we found that the body of evidence relied predominantly on information retrieved from individual cases, and the scientific information provided was heterogeneous. The analysis of types of involvement was biased due to the unbalanced reporting of severe cases over non-severe cases, although the main sources of bias were the heterogeneous definitions of organ involvement (or even the lack of definition in some studies) and the heterogeneous diagnostic approach used in studies to investigate involvment of each organ.
CONCLUSION
The proposals included in this article are a first step to developing an optimal diagnostic approach to systemic involvement in primary SS and may pave the way for further development of evidence-based diagnostic and therapeutic guidelines.

Review
With particular focus on clinical, pathophysiologic and epidemiologic aspects this systematic review article presents the available data on nephrotoxic effects of a long-term treatment with lithium. Lithium may lead to tubular dysfunction (LITD = nephrogenic diabetes insipidus, hyperchloremic metabolic acidosis, increased natriuresis) and lithium-induced nephropathy (LIN) with reduced glomerular filtration rate (GFR). The histopathologic finding of LIN is chronic tubulo-interstitial nephritis. LITD frequently presents with polydipsia/-uria and reduced urine osmolality, while LIN features a wide clinical spectrum ranging from clinically asymptomatic presentations with reduced GFR to end-stage renal failure. LIN seems to feature slow progression and is significantly less frequent than LITD. Regular monitoring of renal function is indispensable for patients treated with lithium. Patients with reduced GFR under treatment with lithium should always be presented to a nephrologist. Currently, there are no guidelines for the handling of patients with LIN and ongoing treatment with lithium. Thus, regarding continuation of lithium-treatment an individual benefit/risk assessment is necessary.

Review
Hypokalemia is a recognized cause of rhabdomyolysis but very few reports document its association with inborn renal tubular disorders. We report our experience with hypokalemic rhabdomyolysis in 5 pediatric patients affected by inborn renal tubular disorders and the results of a careful review of the literature disclosing 9 further cases for a total of 14 patients (8 male and 6 female subjects, aged between 1.6 and 46, median 16 years). The inborn renal tubular disorders underlying rhabdomyolysis were classic distal renal tubular acidosis (n = 7), Gitelman syndrome (n = 5), classic Bartter syndrome (n = 1), and antenatal Bartter syndrome (n = 1). In 8 patients rhabdomyolysis followed an acute intestinal disease, an upper respiratory illness or the discontinuation of regular medication. Five patients experienced two or more episodes of rhabdomyolysis. In 10 patients the underlying renal tubular disorder was recognized concurrently with the episode of rhabdomyolysis or some weeks later. In conclusion some congenital renal tubular disorders predispose to hypokalemic rhabdomyolysis. Prevention of discontinuation of regular medication and electrolyte repair in the context of acute intercurrent illnesses might avoid the development of hypokalemic rhabdomyolysis.
