Enhancing the care of women with rheumatic diseases during pregnancy: challenges and unmet needs in the Middle East.

Pregnancy in women with rheumatic disorders is known to be associated with risks for both the mother and fetus; however, these risks can be minimized with proper planning and careful management of the disease. In the Middle East, there are specific cultural challenges that may have a negative impact on the care that women with rheumatic disorders receive. There is a need for cross-collaboration between specialist physicians, improved awareness of rheumatic disorders among the general public and more open discussion with patients about the potential complications of pregnancy. Women in the region are often unwilling to discuss their disease with their partner and are even less likely to seek advice regarding family planning from their physician. The objective of this review is to highlight the specific challenges of pregnancy management and to discuss why establishing specialist pregnancy clinics for women with rheumatic disorders could be an effective solution. Such clinics can provide high quality care before, during and after pregnancy as shown in several European and US centers. Additionally, such clinics could be useful for the collection of pregnancy outcomes data from the Middle East, which may currently be lacking in the region, in order to highlight where further improvements can be made. With specialist care and analysis of pregnancy outcomes, the standard of care for women with rheumatic disorders in this area could be significantly improved.

Safety and efficacy of infliximab therapy in active behcet's uveitis: an open-label trial.

In this open-label trial, ten male patients with active Behcet's uveitis were enrolled. Initially, two infliximab infusions (5 mg/kg) were given at weeks 0 and 2. The patients continued to receive conventional therapy on recurrence of severe uveitis (RSU) attack. The patients with further attack were regularly given infliximab infusions every 8 weeks. In cases of further RSU attacks, the infusion interval was reduced to 6 weeks. The total follow-up period was 3 years. The patients were monitored for RSU, visual acuity and adverse effects. Reduction in the doses of prednisolone was also monitored. After receiving two infliximab infusions at weeks 0 and 2, three patients remained attack-free and seven patients had another RSU attack between 8th and 47th week. These patients were regularly given infliximab at 8-week intervals. Five out of seven patients remained attack-free. In two patients who had further attack, infusion frequency was increased to 6 weeks. There was a remarkable improvement in visual acuity with no significant adverse reaction except mild respiratory tract infection (two patients), headache (one patient) and mild infusion reaction (one patient). Infliximab is a safe and effective drug for the management of Behcet's uveitis. Selection of optimal dose and frequency of infusion required standardization for individual patient.

Systemic lupus erythematosus and infections: a retrospective study in Saudis.

This study demonstrates demographic, clinical and laboratory characteristics with special reference to infections in Saudi patients with SLE. One-hundred and ninety-nine patients with SLE treated at Riyadh Armed Forces Hospital, Saudi Arabia over a period of 15 years (1990-2005) were retrospectively reviewed. There were 162 females and 37 males (4.4 : 1) with an average age of 35 years at onset of disease. Duration of diseases ranged from one to 23 years with a mean of 7.23 years. Some of the clinical characteristics of SLE patients observed were nephritis (53.7%), fever (53.26%), neuropsychological disorder (36.18%), malar/butterfly rash (27.6%), pulmonary disorder (22.6%), photosensitivity (21.6%), cardiac involvement (21.1%) and oral ulcers (19.09%). Infection was the major complication with 58.79% of SLE patient having suffered from various infections. A total of 22 species of pathogens including gram positive and gram negative bacteria, viruses and fungi were isolated from 117 SLE patients. Single to multiple episode of infection with various pathogens were recorded however, majority of patients harboured one or two species of pathogens. Bacterial infection was predominant (78.6%) followed by viral (28.2%) and fungal (28.2%) infections. Forty-four percent of SLE patients were found to be infected with organisms classified as opportunistic. The high incidence of infections in SLE patients may be attributed to the multiple intrinsic and extrinsic risk factors including deficiency of complement (C3 and C4), disease activity, renal impairment, use of glucocorticoid and cytotoxic drugs. It is concluded that more judicious use of corticosteroids and other immunosuppressive agents will be critical to limit the infections in SLE and a high alert and close monitoring of patients will ensure optimal patient outcome, both in terms of morbidity and mortality.

Leukemic synovitis as a presentation of myelomonocytic blast crisis of chronic myeloid leukemia.

We describe a patient with a 2-month history of right shoulder monoarthritis and fever as the presenting symptoms of a subsequent diagnosis of chronic myeloid leukemia in blast crisis. Imaging studies showed changes consistent with leukemic infiltration of the soft tissues around the right shoulder joint and the proximal humerus. Immunophenotypic and morphologic analysis of the large number of cells obtained from the synovial fluid confirmed the shoulder synovitis to be an extramedullary manifestation of myelomonocytic blast crisis of chronic myeloid leukemia. The patient was not a candidate for aggressive chemotherapy treatment because of her poor overall condition, and she had no compatible donor for allogenic bone marrow transplantation. Her painful arthropathy was refractory to standard pain management but she achieved excellent pain relief with palliative radiation therapy. We conclude that the involvement of extramedullary sites by chronic myeloid leukemia blast cells can predate hematological blast crisis in some of chronic myeloid leukemia cases. Also, painful leukemic synovitis can be managed by low dose radiotherapy in a candidate who is refractory to chemotherapy and other medical therapy.

Systemic lupus erythematosus associated with moyamoya syndrome.

Moyamoya disease is an uncommon clinical entity, characterized by bilateral occlusion of the internal carotid artery and the development of collateral arteries. An 18-year-old Saudi male with systemic lupus erythematosus (SLE) presented with mild right hemiparesis, followed by recurrent ischemic stroke. Cerebral angiography showed bilateral internal carotid artery stenosis associated with the development of collateral circulation (moyamoya vessels). There was no evidence of active SLE or other risk factors for cerebral occlusion, such as antiphospholipid antibody syndrome. Medical and surgical interventions did not influence the poor outcome of the recurrent ischemic insults.

IgE regulation and lymphokine patterns in aging humans.

IgE production declines with age, and allergic symptoms tend to improve. Aging therefore represents an in vivo model to study IgE regulation. We compared IgE production in older (> or = 60 years old) and young (15 to 30 years old) nonatopic individuals. Addition of exogenous interleukin-4 (IL-4) to mononuclear cells from older and young subjects induced equivalent amounts of IgE, indicating that IL-4 responsiveness is preserved in aging. After surface receptor stimulation with concanavalin A, IL-4 production by mononuclear cells from older subjects was approximately 50% as compared with the young, whereas interferon-gamma (IFN-gamma) production was reduced threefold (p = 0.008). By contrast, stimulation with phorbol esters and ionophore, which bypass surface receptor signaling, induced comparable amounts of IL-4 and IFN-gamma in older and young subjects. These data point to an impairment in T-cell membrane signal transduction in older individuals. This hypothesis was directly confirmed by showing that Ca+2 fluxes after CD3 crosslinking were significantly (p = 0.014) decreased in the older population. Our findings altogether suggest that an age-dependent T-cell activation defect may result in decreased availability of IL-4 and in the waning of IgE responses.
