Disseminated Gonococcal Infection Associated with Eculizumab Therapy for Paroxysmal Nocturnal Hemoglobinuria: A Case Report and Literature Review.

ABSTRACT: Eculizumab has been developed as a breakthrough treatment for paroxysmal nocturnal hemoglobinuria (PNH). Not only for breakthroughs, eculizumab therapy is also known to increase the risk of invasive meningococcal infection. It has also been recently reported that, although rarely, administration of eculizumab may result in disseminated gonococcal infection (DGI). We report here a case in which a young patient who had used eculizumab for PNH developed DGI. A 22-year-old Japanese male with PNH who had been treated with eculizumab complained of high fever, mild nausea, headache and right knee joint pain. The patient was admitted and suspected to have sepsis due to meningococcal infection and began to receive ceftriaxone (CTRX). Gonococci were detected in a venous blood culture a few days later, and this case was diagnosed as DGI. CTRX was effective, and the patient was discharged. However, four weeks later, he complained of the same subjective symptoms as at the beginning and was hospitalized again. The presence of gonococcus was proven by venous blood culture, CTRX was re-administered and the patient responded. After discharge, he was counseled on safer sexual activity, including accurate and consistent use of condoms, by urologists. He has not relapsed with DGI for more than one year. When serious signs of infection occur in patients receiving eculizumab, it is recommended to consider DGI as well as invasive meningococcal infection, and CTRX should be given.

Project description:AimsParoxysmal nocturnal hemoglobinuria (PNH) is a rare and life-threatening intravascular hematologic disorder with significant morbidity and premature mortality. Clinical trials (NCT02946463 and NCT03056040) comparing ravulizumab with eculizumab for PNH have supported the non-inferiority of the former and similar safety and tolerability. This secondary analysis compared PNH trial participants after 26 weeks on either treatment (n = 438) to a general-population sample (GenPop) (n = 15,386) and investigated response-shift effects.MethodsMultivariate analysis of covariance (MANCOVA) investigated function and symptom scores on the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 of people with PNH as compared to GenPop, after covariate adjustment. Risk-factor groups were created based on clinical indicators known to be associated with worse PNH outcomes, and separate MANCOVAs were computed for lower- and higher-risk-factor groups. Differential item functioning (DIF) analyses examined whether item response varied systematically (1) by treatment, (2) compared to GenPop, and (3) over time, the latter two suggesting and reflecting response-shift effects, respectively. DIF analyses examined 24 items from scales with at least two items. Recalibration response shift was operationalized as uniform DIF over time, reflecting the idea that, for a given group, the difficulty of endorsing an item changes over time, after adjusting for the total subscale score. Reprioritization response shift was operationalized as non-uniform DIF over time, i.e., the relative difficulty of endorsing an item over time changes across the total domain score.ResultsAcross PNH risk-factor levels, people who had been on either treatment for 26 weeks reported better-than-expected functioning and lower symptom burden compared to GenPop. Ravulizumab generally showed larger effect sizes. Results were similar for lower and higher PNH risk factors, with slightly stronger effects in the former. DIF analyses revealed no treatment DIF, but did uncover group DIF (9 items with uniform DIF, and 11 with non-uniform) and DIF over time (7 items with uniform DIF, and 3 with non-uniform).ConclusionsThis study revealed that people with PNH on ravulizumab or eculizumab for 26 weeks reported QOL levels better than those of the general population. Significant effects of DIF by group and DIF over time support recalibration and reprioritization response-shift effects. These findings suggest that the treatments enabled adaptive changes.
