Abstract Introduction Obeticholic acid (OCA) is a semi-synthetic hydrophobic bile acid (BA) analogue that is highly selective agonist of farnesoid X receptor (FXR), a key nuclear BA receptor, which induces expression of gut-derived hormones, in particular fibroblast growth factor 19. The resulting beneficial effects of OCA on glucose and lipid metabolism and particularly hepatic inflammation make it a candidate for the treatment of a variety of conditions including primary biliary cholangitis (PBC) and nonalcoholic steatohepatitis (NASH). Sources of data In PBC patients who have not initially responded to ursodeoxycholic acid, OCA has been shown in double-blind controlled clinical trials to significantly reduce serum alkaline phosphatase. To date, OCA is the only therapy licensed by the FDA, EMA and endorsed by NICE as second line therapy for PBC. No medications are currently approved in Europe or the USA for the treatment of NASH. In recent clinical trials, OCA has been shown encouraging results by improving liver blood tests and reducing liver fibrosis with no worsening of NASH. Areas of agreement OCA is the established second line therapy for PBC in those patients who fail to adequately respond to ursodeoxycholic acid. Areas of controversy The main side effects of OCA treatment in both PBC and NASH is that of dose-dependent pruritis which can lead to treatment discontinuation in ~1–10% of patients. In addition, OCA-treated patients may also exhibit (reversible) alterations in serum lipid levels; most notably a small decrease in high density lipoprotein cholesterol. It is not yet known whether these changes carry a long-term cardiovascular risk in NASH. In addition, the relatively high cost of OCA may limit its use in cash-limited health systems. Growing Points Additional clinical trials are in progress to ascertain the long-term effects of OCA on survival in PBC and NASH. Areas timely for developing research New FXR agonists with a lower rate of side effects are being developed and trialed. Combination therapy with other agents may offer increased efficacy.

Abstract Autoimmune hemolytic anemia is a heterogeneous disease with respect to the type of the antibody involved and the absence or presence of an underlying condition. Treatment decisions should be based on careful diagnostic evaluation. Primary warm antibody autoimmune hemolytic anemias respond well to steroids, but most patients remain steroid-dependent, and many require second-line treatment. Currently, splenectomy can be regarded as the most effective and best-evaluated second-line therapy, but there are still only limited data on long-term efficacy and adverse effects. The monoclonal anti-CD20 antibody rituximab is another second-line therapy with documented short-term efficacy, but there is limited information on long-term efficacy and side effects. The efficacy of immunosuppressants is poorly evaluated. Primary cold antibody autoimmune hemolytic anemias respond well to rituximab but are resistant to steroids and splenectomy. The most common causes of secondary autoimmune hemolytic anemias are malignancies, immune diseases, or drugs. They may be treated in a way similar to primary autoimmune hemolytic anemias, by immunosuppressants or by treatment of the underlying disease.
