An overview of the effects of sickle cell disease in adolescents.

Specific complications of sickle cell disease (SCD) may emerge during adolescence, and education of patients and families is vital during transition from paediatric to adult health care. Adolescents with SCD have to adjust to the constraints of living with a lifelong chronic condition, and compliance with self-care and medical treatments can be problematic. This article explores potential opportunities for intervention, and examines how the role of the adolescent clinical nurse specialist is pivotal in supporting patients and families during this transition.

A prospective diary study of stuttering priapism in adolescents and young men with sickle cell anemia: report of an international randomized control trial--the priapism in sickle cell study.

Priapism is defined as a prolonged, persistent, and purposeless penile erection. It is a common (35%) but frequently understated complication in young men and adults with sickle cell disease. We had previously demonstrated an association between stuttering attacks (<4 hours) and an acute catastrophic event with its consequent problems of erectile dysfunction and impotence. We describe a randomized, placebo-controlled, clinical study looking at medical prophylaxis with 2 oral α-adrenergic agonists, etilefrine and ephedrine, in preventing stuttering attacks of priapism. One hundred thirty-one patients were registered into a 2-phase (observational and intervention phase) study, and 86 patients (66%) completed Phase A diary charts. Forty-six patients (59%) completed a 6-month treatment phase (Phase B), and the remaining patients were lost to follow-up despite persistent efforts to contact them. Various reasons are postulated for the high attrition rates. The drugs were well tolerated, and no serious adverse events were reported. There was no significant difference among the 4 treatment groups in the weekly total number of attacks in Phase B (analysis of covariance P = .99) nor among the average pain score per attack after adjusting for attack rates and pain scores in Phase A (analysis of covariance P = .33). None of the patients who completed the study required penile aspiration at study sites while on medical prophylaxis. Young men with sickle cell disease are not comfortable engaging with health care providers about issues relating to their sexual health. The full impact of an improved awareness campaign and early presentation to hospital merits further standardized study. Priapism still contributes seriously to the comorbidity experienced by this previously inaccessible group of patients and medical prophylaxis with oral α-adrenergic agonists is feasible. Future international collaborative efforts using some of the lessons learnt in this study should be undertaken.

The comprehensiveness care of sickle cell disease.

Millions of people across the world have sickle cell disease (SCD). Although the true prevalence of SCD in Europe is not certain, London (UK) alone had an estimated 9000 people with the disorder in 1997. People affected by SCD are best managed by a multidisciplinary team of professionals who deliver comprehensive care: a model of healthcare based on interaction of medical and non-medical services with the affected persons. The components of comprehensive care include patient/parent information, genetic counselling, social services, prevention of infections, dietary advice and supplementation, psychotherapy, renal and other specialist medical care, maternal and child health, orthopaedic and general surgery, pain control, physiotherapy, dental and eye care, drug dependency services and specialist sickle cell nursing. The traditional role of haematologists remains to co-ordinate overall management and liase with other specialities as necessary. Co-operation from the affected persons is indispensable to the delivery of comprehensive care. Working in partnership with the hospital or community health service administration and voluntary agencies enhances the success of the multidisciplinary team. Holistic care improves the quality of life of people affected by SCD, and reduces the number as well as length of hospital admissions. Disease-related morbidity is reduced by early detection and treatment of chronic complications. Comprehensive care promotes awareness of SCD among affected persons who are encouraged to take greater control of their own lives, and achieves better patient management than the solo efforts of any single group of professionals. This cost-effective model of care is an option for taking haemoglobinopathy services forward in the new millennium.
