Nesidioblastosis as the cause of hyperinsulinaemic hypoglycaemia in an adult is rare. We report here an additional case of nesidioblastosis, which resulted in fatal hyperinsulinaemic hypoglycaemia in a 72-year-old woman with an underlying myelodysplastic syndrome. The diagnosis of nesidioblastosis was established only after post-mortem examination with a careful exclusion of minute insulinoma. To our surprise, the renal pathology disclosed typical diabetic nodular glomerulosclerosis in the same patient who had no previous history of diabetes mellitus (DM). Nesidioblastosis has been reported to cause 'reversal' of Type 1 DM and insulinoma causing 'reversal' of Type 2 disease. We therefore hypothesize that our patient might have had an undiagnosed DM in the past, which resulted in the typical diabetic nodular glomerulosclerosis. The nesidioblastosis caused a 'reversal' of DM and even the ultimate development of hyperinsulinaemic hypoglycaemia.

Myelodysplastic syndrome is a clonal hematopoietic stem cell disorder characterized by ineffective hematopoiesis, peripheral cytopenias and an additional risk to evolve to acute leukemia in up to 30% of the cases. Autoimmune manifestations as vasculitis, pyoderma gangrenosum, hemolytic anemia, immune thrombocytopenia, rheumatoid arthritis as well as positive anti-nuclear factor and rheumatoid factor have been reported in 13-30% of MDS patients. The aim of this report is to present three patients with 5q- syndrome who presented different autoimmune serological and clinical phenomena and review the literature. Patient 1 showed a focal and segmental glomerulosclerosis (FSGE) in the course of a MDS. Renal involvement in MDS as autoimmune phenomenon is rare and few reports have documented different forms of glomerular diseases in adults with MDS. Patients 2 and 3 showed a rheumatoid factor of 1/140 and the direct Coomb's test positive (3+), respectively, but without evidence of clinical autoimmune manifestation. In conclusion, patients with the 5q- syndrome experience a relative benign disease course extending over several years. We believe that careful follow-up of patients with autoimmune manifestations as here reported is important to detect any unexpected outcome.
