The results suggest that a national screening programme should be implemented in Burkina Faso with effective newborn and subsequent follow-up, but a methodology needs to be developed.
Interstitial pneumonitis is a classical complication of many drugs. Pulmonary toxicity due to 5-azacytidine, a deoxyribonucleic acid methyltransferase inhibitor and cytotoxic drug, has rarely been reported. We report a 67-year-old female myelodysplastic syndrome patient treated with 5-azacytidine at the conventional dosage of 75 mg/m2 for 7 days. One week after starting she developed moderate fever along with dry cough and subsequently her temperature rose to 39.5 °C. She was placed under broad-spectrum antibiotics based on the protocol for febrile neutropenia, including ciprofloxacin 750 mg twice daily, ceftazidime 1 g three times daily (tid), and sulfamethoxazole/trimethoprim 400 mg/80 mg tid. High-resolution computed tomography of the chest disclosed diffuse bilateral opacities with ground-glass shadowing and pleural effusion bilaterally. Mediastinal and hilar lymph nodes were moderately enlarged. polymerase chain reaction for Mycobacterium tuberculosis, Pneumocystis jiroveci, and cytomegalovirus were negative. Cultures including viral and fungal were all negative. A diagnosis of drug-induced pneumonitis was considered and, given the negative bronchoalveolar lavage in terms of an infection, corticosteroid therapy was given at a dose of 1 mg/kg body weight. Within 4 weeks, the patient became afebrile and was discharged from hospital. Development of symptoms with respect to drug administration, unexplained fever, negative workup for an infection, and marked response to corticosteroid therapy were found in our case. An explanation could be a delayed type of hypersensitivity (type IV) with activation of CD8 T cell which could possibly explain most of the symptoms. We have developed a decision algorithm in order to anticipate timely diagnosis of 5-azacitidine-induced pneumonitis, and with the aim to limit antibiotics abuse and to set up emergency treatment.
The purpose of this study is the prevalence of the rheumatologic complications in the sickle cell disease and the associations between haemoglobinopathies and rheumatologic affections. It is a retrospective study from 29 February 2006 to 28 March 2008 conducted in the Internal Department of the University Hospital Yalgado-Ouédraogo. All patients received in the period of study and having an electrophoresis of haemoglobin realized in alkaline pH were included. These patients came from hematologic consultation. Two hundred and seventy-seven patients out of 1451 were included: 142 patients (51.30%) had haemoglobinopathies, including 21 (7.60%) with composite sickle cell disease SC and 17 patients (6.13%) had aseptic necrosis of the femoral head including 7 with haemoglobin SC. The other rheumatologic affections did not have a semiological particularity related to the type of haemoglobin. The prevalence of patients who have haemoglobinopathies is important in rheumatologic practice. The sickle cell disease is strongly associated to osteonecrosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
