The burden of disease and quality of life in patients with acute hepatic porphyria: COPHASE study

BACKGROUND

Acute hepatic porphyria (AHP) comprises a group of rare genetic diseases characterized by neurovisceral crises that are manifested by abdominal pain and neurological and/or psychological symptoms that interfere with the ability to lead a normal life. Our objective was to determine the burden of the disease in one year and the health-related quality of life (HRQoL) in patients with AHP.

RESULTS

28 patients were analyzed. The mean age was 36.6±10.2 years, 89.3% were women, and the average number of crises was 1.9±1.5. The average annual cost per patient was €38,255.40. 80.2% of the costs was direct medical costs, 17.5% was associated with loss of productivity and 2.3% was direct non-medical costs. 85.9% of the total cost corresponded to the crises. The intercrisis period accounted for the remaining 14.1%. The global index of the EQ-5D-5L (HRQoL) was 0.75±0.24. The dimensions of pain/discomfort, anxiety/depression and daily activities were the most affected. Leisure, travel/vacations and household activities were the most affected daily activities. 53.6% of patients required a caregiver due to AHP. 92.9% did not present overload and 7.1% presented extreme overload.

CONCLUSIONS

Patients with AHP are associated with a high economic impact and an affected HRQoL in the pain/discomfort dimension, with a negative impact on the performance of daily activities and a risk of psychiatric diseases.

Risk of mayor and minor birth defects in children conceived by assisted reproductive technology (IVF/ICSI): A prospective controlled cohort study

INTRODUCTION

About 0.2-6.1% of newborns in the developed world have been conceived by assisted reproductive techniques (ART). Higher rate of major and minor malformations have been described in this population, but the multiple possible confounders associated make it difficult to establish a direct causal relationship and the specific factors involved.

MATERIAL AND METHODS

To determine the risk of these malformations in our population, a collaborative prospective controlled cohort study was designed. We collected the specific ART-data related to the clinical gestation of women treated in a period of 2 years in the Reproduction Unit from a Spanish public tertiary-level hospital. 231 out of 267 newborns of these gestation (88%) participated in the study and were assessed by a pediatrician with expertise in Clinical Genetics and Dysmorphology at 12-20 and 26-40 months of age. At the same time a controlled group of children naturally conceived (NC) was selected according to the following criteria: the next NC newborn belonging to the same group of maternal and gestational age, and type of gestation (single or multiple). 230 controls were chosen and 208 participated in the study (90%).

RESULTS

Major malformations were presented in 7.8% of the ART-children and 7.2% of the controls, without founding statistically differences between groups. However, differences were found in the risk of some minor malformations such as capillary malformations and pigmentary lesions, higher in the ART-group. A recurrent pattern of craneofacial anomalies was also unexpectedly detected.

CONCLUSIONS

In spite of the high rate of major congenital malformations detected, there were no differences between groups. Thus, our results suggest that ART may affect the normal embryonic development but in a milder way than other confounding factors do. The facial phenotype identified has not previously been described, either the higher risk of capillary malformations and pigmentary lesions. More studies are needed to confirm this association.

Craniosynostosis in Kabuki syndrome

Niikawa-Kuroki, or Kabuki syndrome (KS), is characterized by distinctive facial features, skeletal anomalies, persisting fingertip pads with dermatoglyphic abnormalities, short stature, and mental retardation. Neurological manifestations and CNS anomalies have been described in some patients with this condition. However, craniosynostosis has been documented in only 4 patients with KS who did not undergo operations. The authors report a case of KS with unicoronal synostosis that constitutes the first documented instance of a patient with this syndrome submitted to surgery. Previous reported instances of craniosynostosis occurring in KS are briefly reviewed. Although rarely documented, craniosynostosis might represent a relatively frequent feature of this syndrome. Kabuki syndrome should be considered at the time of evaluating children with craniosynostosis. The diagnosis of KS can be suspected from the patients' characteristic facial features. Kabuki syndrome appears to be an underdiagnosed condition in the craniosynostosis population. Given that most patients with this syndrome suffer from only mild to moderate mental retardation, surgical correction can be considered in instances of KS with craniosynostosis.

De novo interstitial tandem duplication of chromosome 4(q21-q28)

We describe a girl with a previously unreported de novo duplication of chromosome 4q involving segment q21-q28. Clinical manifestations included growth and psychomotor retardation, facial asymmetry, hypotelorism, epicanthic folds, mongoloid slant of palpebral fissures, apparently low-set auricles, high nasal bridge, long philtrum, small mouth, short neck, low-set thumbs, and bilateral club foot. This phenotype is compared with that of previously reported cases of duplication 4q.
