CONTEXT AND OBJECTIVE: Patients with beta-thalassemia major (β-TM) experience physical, psychological and social problems that lead to decreased quality of life (QoL). The aim here was to measure health-related QoL and its determinants among patients with β-TM, using the Short Form-36 (SF-36) questionnaire. DESIGN AND SETTING: Cross-sectional study at the Hematology Research Center of Shiraz University of Medical Sciences, in southern Iran. METHODS: One hundred and one patients with β-TM were randomly selected. After the participants' demographics and disease characteristics had been recorded, they were asked to fill out the SF-36 questionnaire. The correlations of clinical and demographic factors with the QoL score were evaluated. RESULTS: There were 44 men and 57 women of mean age 19.52 ± 4.3 years (range 12-38). On two scales, pain (P = 0.041) and emotional role (P = 0.009), the women showed significantly lower scores than the men. Lower income, poor compliance with iron-chelating therapy and presence of comorbidities were significantly correlated with lower SF-36 scores. These factors were also found to be determinants of worse SF-36 scores in multivariate analysis. CONCLUSIONS: We showed that the presence of disease complications, poor compliance with ironchelating therapy and poor economic status were predictors of worse QoL among patients with β-TM. Prevention and proper management of disease-related complications, increased knowledge among patients regarding the importance of managing comorbidities and greater compliance with iron-chelating therapy, along with psychosocial and financial support, could help these patients to cope better with this chronic disease state. RESUMO
Juvenile Paget’s disease (JPD) is a rare heritable osteopathy characterized biochemically by markedly increased serum alkaline phosphatase (ALP) activity emanating from generalized acceleration of skeletal turnover. Affected infants and children typically suffer bone pain and fractures and deformities, become deaf, and have macrocranium. Some who survive to young adult life develop blindness from retinopathy engendered by vascular microcalcification. Most cases of JPD are caused by osteoprotegerin (OPG) deficiency due to homozygous loss-of-function mutations within the TNFRSF11B gene that encodes OPG. We report a 3-year-old Iranian girl with JPD and craniosynostosis who had vitamin D deficiency in infancy. She presented with fractures during the first year-of-life followed by bone deformities, delayed development, failure-to-thrive, and pneumonias. At 1 year-of-age, biochemical studies of serum revealed marked hyperphosphatasemia together with low-normal calcium and low inorganic phosphate and 25-hydroxyvitamin D levels. Several family members in previous generations of this consanguineous kindred may also have had JPD and vitamin D deficiency. Mutation analysis showed homozygosity for a unique missense change (c.130T>C, p.Cys44Arg) in TNFRSF11B that would compromise the cysteine-rich domain of OPG that binds receptor activator of NF-κB ligand (RANKL). Both parents were heterozygous for this mutation. The patient’s serum OPG level was extremely low and RANKL level markedly elevated. She responded well to rapid oral vitamin D repletion followed by pamidronate treatment given intravenously. Our patient is the first Iranian reported with JPD. Her novel mutation in TNFRSF11B plus vitamin D deficiency in infancy was associated with severe JPD uniquely complicated by craniosynostosis. Pamidronate treatment with vitamin D sufficiency can be effective treatment for the skeletal disease caused by the OPG deficiency form of JPD.
Objective Despite premarital screening, prenatal diagnosis and the option for voluntary termination of pregnancy, some Iranian couples continue a pregnancy with a fetus affected with beta-thalassaemia major (b-TM). We examined the reasons for this decision, to evaluate the sociocultural challenges these couples face. Methods A retrospective evaluation of medical records of all fetuses aborted was conducted to identify those with b-TM, to determine the frequency of b-TM births and to establish the number of couples with b-thalassaemia who declined prenatal diagnosis or a termination of pregnancy in this period. We investigated the reasons for declining these options. Results The birth prevalence of b-TM decreased from 39.38 to 2.68 in 100,000 live births from 2005 to 2010. Terminations of pregnancy for affected fetuses increased from 67 in 2005 to 135 in 2010. We identified eight couples as b-thalassaemia carriers who declined prenatal diagnosis or a termination of pregnancy. All but one couple already had a child with b-TM. The reasons for declining prenatal diagnosis were strong religious beliefs, superstition and faith in a supernatural solution in six couples. Economic and cultural factors, and previous termination of pregnancy were also mentioned as reasons by the other two couples. Conclusion Although most of the couples had a b-TM child and related socioeconomic problems, their reasons for refusing prenatal diagnosis or termination remain a challenge for the healthcare system in Iran. Couple screening and educational programmes have effectively decreased the rates of refusal in at-risk couples in recent years.
