Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease, ranging from pure steatosis to non-alcoholic steatohepatitis and ultimately to liver cirrhosis. In our study, adult NAFLD patients did not have different oxalate excretion values [ -0.26 (95% CI -1.59-1.08), I P i =.681] and only altered urinary ammonium and magnesium excretions were found as proposed risk factors for nephrolithiasis (Fig. Our findings indicate the need for further prospective studies to compare the characteristics of NAFLD patients with and without nephrolithiasis and its incidence at different degrees of NAFLD severity to expand on the observations reported here.

Objectives The biomarkers of an immunological dysregulation due to a chronic HBV infection are indeed understudied. If untreated, this condition may evolve into liver impairment co-occurring with extrahepatic involvements. Here, we aim to identify a new panel of biomarkers [including immunoglobulin G (IgG) subclasses, RF, and Free Light Chains (FLCs)] that may be useful and reliable for clinical evaluation of HBV-related cryoglobulinemia. Methods We retrospectively analysed clinical data from 44 HBV-positive patients. The patients were stratified (according to the presence/absence of mixed cryoglobulinemia) into two groups: 22 with cryoglobulins (CGs) and 22 without CGs. Samples from 20 healthy blood donors (HDs) were used as negative controls. Serum samples were tested for IgG subclasses, RF (-IgM, -IgG, and -IgA type), and FLCs. Results We detected a strikingly different distribution of serum IgG subclasses between HDs and HBV-positive patients, together with different RF isotypes; in addition, FLCs were significantly increased in HBV-positive patients compared with HDs, while no significant difference was shown between HBV-positive patients with/without mixed cryoglobulinemia. Conclusion The immune-inflammatory response triggered by HBV may be monitored by a peculiar profile of biomarkers. Our results open a new perspective in the precision medicine era; in these challenging times, they could also be employed to monitor the clinical course of those COVID-19 patients who are at high risk of HBV reactivation due to liver impairment and/or immunosuppressive therapies.
