Background: Chemotherapy (CT)-induced neutropenia and febrile neutropenia (FN) can lead to changes in the treatment plan, potentially worsening the cancer outcome. This study evaluated the effect of the glycopegylated granulocyte-colony stimulating factor lipegfilgrastim, used as primary (PP) or secondary prophylaxis (SP), on treatment modifications in adult patients receiving cytotoxic CT with or without biological/targeted therapy (BT) for solid and haematological tumours., Methods: This phase 4, prospective, observational study was conducted in eight centres in the Netherlands, in 2015-2017. Other study objectives were to characterise the population of cancer patients receiving lipegfilgrastim, to evaluate the incidence of CT-induced neutropenic events, and to assess safety., Results: Of 142 patients, 73.94% had breast cancer and 55.63% received CT in the adjuvant setting. Most patients received lipegfilgrastim as PP (74.65%) and were at low (34.51%) or high risk (39.44%) of FN. CT dose delays were recorded for 22.64% and 36.11% of patients receiving lipegfilgrastim for PP and SP, respectively. CT dose reductions were recorded for 2.11% of patients; no CT dose omissions and one BT dose omission occurred. FN and grade III/IV neutropenia were reported for 5.63% and 9.86% of patients, respectively; associated hospitalisations were rare. The most frequently lipegfilgrastimrelated adverse events (AE) were myalgia, bone pain, and back pain. Serious AEs (55) were reported for 30 (21.13%) patients. There were two deaths, unrelated to lipegfilgrastim administration., Conclusion: Administration of lipegfilgrastim in routine clinical practice in the Netherlands results in limited CT/BT dose modifications and low incidence of neutropenic events, with no new safety concerns.

Lenalidomide has a central role in the treatment of multiple myeloma and results in improved survival. As with other chemotherapeutics, it can cause several serious side effects. This is the first reported case of hepatitis E during lenalidomide treatment for multiple myeloma in complete remission. In case of liver chemistry abnormalities during lenalidomide treatment, the differential diagnosis should include hepatitis E infection.

Hereditary haemochromatosis is an autosomal recessive disorder, leading to progressive iron overload, which is very common among the Caucasian population. In the vast majority of the cases, the hereditary iron overload is caused by mutations in the HFE gene. Most prominently this is the homozygous Cys282Tyr mutation. We report two Dutch families in which both propositi were found to be heterozygous for Cys282Tyr in the work-up of hyperferritinaemia. Frequent phlebotomies had no effect on the ferritin level, but led to microcytic anaemia. Finally, the family history with bilateral cataracts was the clue for the correct diagnosis. Hereditary hyperferritinaemia-cataract syndrome (HHCS) is an autosomal dominant disease characterised by elevated serum ferritin levels and bilateral cataracts in the absence of iron overload. Several point mutations and deletions within the iron-responsive element (IRE) in the 5' noncoding region of the L-ferritin gene have been found in HHCS families. In the first Dutch family a G to C transition at position 32 was found and a G to A mutation at the same location was found in the second Dutch family. In individuals with an isolated hyperferritinaemia (normal transferrin saturation), the presence of early onset (familial) cataract should raise the possibility of HHCS, even when Cys282Tyr heterozygosity is found.

We describe our experience with sodium citrate as anticoagulant in the haemodialysis of 15 patients who were at high risk for bleeding. Furthermore, in six of these patients who were on prolonged citrate dialysis, the last month of heparin dialysis was compared with the first month in which citrate was used as anticoagulant. Our series confirms the suitability of citrate as anticoagulant in patients who are at high risk for bleeding. In the prolonged citrate dialysis group, however, there were complaints of paraesthesias. Probably, the citrate-induced metabolic alkalosis and the relatively low serum calcium concentration observed in these patients contributed to these complaints. To limit these side effects the acetate concentration in the dialysate needs to be reduced and, as magnesium also complexes with citrate, a calcium- and magnesium-free dialysate should be used to reduce the citrate infusion rate and thus the alkaline load in these patients. Furthermore, lowering the calcium infusion rate in order to lower the citrate infusion rate is not indicated because this induces low serum calcium concentration.
