Whether it is better to treat renal transplant patients with cyclosporine alone, combined with steroids, or combined with steroids and azathioprine is still unclear. After initial therapy with cyclosporine and steroids, 354 cadaver renal transplant recipients were randomly assigned at the post-transplant day 5 to cyclosporine alone (monotherapy), cyclosporine plus steroids (double therapy), or cyclosporine plus steroids plus azathioprine (triple therapy). Monotherapy patients, after a second acute rejection, were switched to either of the two alternative therapies. According to intention-to-treat (ITT) analysis, the 4-year patient survival was 97% in monotherapy, 91% in double therapy, and 96% in triple therapy; the graft survival including death was 84%, 77%, and 88%, respectively; and the pure graft survival was 87%, 85% and 91%, respectively (P = not significant). Acute rejections were diagnosed in 79 patients in monotherapy, 58 in double therapy, and 59 in triple therapy (P < 0.01). Of the patients on monotherapy, 52% were switched to double or triple therapy. In these patients, the 4-year graft survival including death was 68%, and the pure graft survival was 72%, in comparison with 93% and 94%, respectively, for patients who continued on cyclosporine alone. Patients with renal polycystic disease as a cause of renal failure and with low plasma creatinine at the time of randomization (5 days after transplant) had a higher probability of remaining on monotherapy, wherease those with glomerulonephritis or systemic lupus erythematosus (SLE) and with high plasma creatinine levels at randomization had a higher probability of being switched to double or triple therapy. According to ITT analysis, there were fewer ocular (P < 0.0001), osteomuscular (P < 0.002) and cardiovascular complications (P = 0.05) and fewer patients with hypercholesterolemia (P < 0.0028) in the monotherapy group, with no difference between double and triple therapy. Creatinine clearance at 3 years was lower in monotherapy, but no attrition of renal function was seen over the years in any of the groups. Cyclosporine, however used, provided good results in cadaveric renal transplantation. Triple therapy and monotherapy offered a nonsignificantly better patient and graft survival than double therapy. Patients on monotherapy had a higher risk of acute rejection but had fewer adverse events than those on double or triple therapy. Patients maintained on cyclosporine alone had the best graft survival, whereas those who were assigned to monotherapy and had to add steroids because of multiple rejections had the worst outcome. Therefore, it seems reasonable to limit the choice of monotherapy to patients without immune-mediated renal diseases and with good graft function in the early post-transplant period.

To identify intrinsic defects in lupus, we studied short-term, CD4(+) T cell lines that were established from 16 lupus patients (active or inactive) and 15 normal subjects by stimulating once with anti-CD3, anti-CD28, and IL-2. After resting, the pure CD4(+) T cells were exposed to anergy-inducing stimulation with plate-bound anti-CD3 mAb in the absence of APC. Lupus T cells showed prolonged high level expression of CD40 ligand (CD40L, CD154) even in the face of anergy protocol, which shut down CD40L expression in normal T cells. The sustained CD40L expression in lupus T cells did not correlate with memory status or Th deviation, and was relatively independent of IL-2 or other autocrine or paracrine signals via CD28 or CTLA-4. Cyclosporin A could block CD40L expression by lupus T cells when added early during the anti-CD3 stimulation period, but only partially when added later, indicating that another mechanism regulates the prolonged hyperexpression of CD40L besides the Ca(2+) --> calcineurin-dependent NF-AT pathway. When exposed to the anergy protocol, lupus T cells, in marked contrast to normal T cells, did not phosphorylate Cbl/Cbl-b but continued to express strongly phosphorylated extracellular signal-regulated kinase (ERK); U0126, a specific inhibitor of mitogen-activated protein kinase kinase --> ERK, could block both the early and the prolonged hyperexpression of CD40L. Thus, pathways regulating the activities of Cbl and one particular mitogen-activated protein kinase, ERK, are involved in the prolonged hyperexpression of CD40L in lupus T cells.

We report a 55-year-old woman with bullous systemic lupus erythematosus, who later developed pyoderma gangrenosum (PG). Dapsone was effective for the eruption of bullous bullous systemic lupus erythematosus but not for pyoderma gangrenosum. Cyclosporine was effective for the skin lesions of pyoderma gangrenosum. This is the first reported case of PG associated with bullous systemic lupus erythematosus.

Anemia is common with connective tissue disorders, but pancytopenia is rare. We report a 22-year-old female who presented with menorrhagia, seizures, anemia, leukocytosis, thrombocytopenia, pericardial effusion, positive ANA, and evidence of vasculitis on CT head scan and was diagnosed with systemic lupus erythematosus (SLE). After 7 months of remission, she was readmitted with menorrhagia and pancytopenia. Investigations revealed aplastic anemia. She survived on transfusion support for 6 weeks, during which period she received methylprednisolone and cyclophosphamide pulses, and phenytoin was omitted but to no avail. Cyclosporine (300 mg/day) was started and the aplastic anemia responded. After 4 months of therapy, the cyclosporine was gradually tapered over the next 2 months. The patient has been on 10 mg/day of prednisolone for the last 6 months. Aplastic anemia is rare in SLE and the response to immunosuppressants is variable, but here is a success story.

"Dry eye syndrome" is a common disorder of the tear film that results from inadequate tear production, excessive tear evaporation or abnormality in mucin or lipid components of the tear film. A number of 53 patients suffering from dry eye syndrome were followed up for a period of 18 months. The study group was heterogeneous, including a lot of conditions accompanied by dry eye syndrome: Syogren's syndrome, lupus erythematous, ocular rosacea, patients with systemic treatments with antidepressants, betablockers, diuretics, oral contraceptives, glaucomatous patients with topical beta-blockers, postmenopausal women, aging people, computer users and long-term contact lens wearers. The therapeutical options were dictated by the severity of the syndrome: substitution therapy, treatment of the underlying eyelid diseases, modifying of the environmental conditions and treatment of the complications in the most severe cases. The new pathological approach is innovative and it may provide a real therapeutical measure for this condition: topical A Cyclosporine and androgen drops.

Rheumatic diseases occur frequently in women of childbearing years necessitating drug treatment also during a concurrent pregnancy in order to control maternal disease activity and to ensure a successful pregnancy outcome. This survey reviews maternal and fetal side effects of nonsteroidal anti-inflammatory drugs (NSAID) and immunosuppressive agents in pregnant patients. The classic nonselective nonsteroidal anti-inflammatory drugs are not teratogenic, but given in late pregnancy they can induce renal and cardiac side effects in the fetus. Similar effects must be expected of the new, selective Cox2-inhibitors. NSAID should therefore be stopped by gestational week 32. Corticosteroids are frequently necessary to control rheumatic disease flares and for prevention of serious organ manifestations. However, due to an increased risk of oral clefts, high doses (1-2 mg/kg) should be avoided in the first trimester. Among disease modifying drugs, sulfasalazine and antimalarials have the safest record. Cyclosporine and azathioprine can be given throughout pregnancy if disease control requires it. Insufficient data exist for treatment of pregnant patients with TNF-inhibitors and mycophenolate mofetil. The severity of the disease under treatment decides if continuation of one of these drugs is justified. Prophylactic withdrawal of drugs before pregnancy is mandatory for leflunomide and the cytotoxic agents methotrexate and cyclophosphamide. Prepregnancy counselling and careful monitoring during pregnancy help to tailor necessary drug treatment for the benefit of mother and child.

A 51 year old woman with systemic lupus erythematosus (SLE) serially developed thrombocytopenia, arthritis, lupus nephritis, pleuritis, mesenteric vasculitis and refractory hemolytic anemia during the past 19 years prior to presentation. The woman had been managed with high doses of prednisolone, splenectomy, methylprednisolone pulse therapy and cytotoxic drugs, including oral cyclophosphamide, azathioprine, mexotrexate and monthly parenteral cyclophosphamide for hemolytic anemia. After two months of therapeutic trial with Cyclosporin A (CsA) (3 mg/kg), the follow-up hemoglobin (Hb) level was increased to 12.0 gm% and the dose ofprednislone was reduced to 5 mg every other day without occurring rebound during the subsequent three months. There were no obvious side effects from the medication.

A 32-year-old Japanese woman, who had a treatment history of systemic lupus erythematosus (SLE) with lupus nephritis World Health Organization class IV for 11 months, visited our hospital due to fever, facial erythema, and erosion of the oral cavity on November 10, 2003. Her mucosal erosion and facial skin erythema progressed over the following week, and Stevens-Johnson syndrome was diagnosed due to pathological findings of the skin. Among the administrated drugs, only mizoribine, started 6 months earlier, produced a positive reaction in the drug lymphocyte stimulation test. Increased prednisolone and high dose intravenous gamma-globulin were given successfully. Cyclosporine at 50 mg was administered to control the SLE, followed by an increase to 100 mg on January 7, 2004. She suffered from abdominal pain, blindness, and convulsion on January 9. The magnetic resonance image of her brain prompted a diagnosis of reversible posterior leukoencephalopathy syndrome. After withdrawal of cyclosporine and control of hypertension, symptoms disappeared rapidly. Cyclophosphamide pulse therapy was successfully administrated to control lupus nephritis. This is the first report describing the relationship between Stevens-Johnson syndrome and mizoribine. Although the use of mizoribine is thought to be safe, careful observation is necessary.

Systemic Lupus Erythrematosus (SLE) is an inflammatory autoimmune disorder that may affect multiple organ systems. The clinical course is marked by spontaneous remission and relapses. Severity may vary from mild episodic disorder to a rapidly fulminant life threatening illness. Clinical manifestations of Lupus Nephritis (LN) are varied according to the renal pathologic lesions. Treatment of LN remains controversial. As a chronic disease with periods of remission and relapses, it is unclear whether relapses should be treated as the initial presentation of the disease. This prospective study was designed to compare between three different modalities of therapy for treating LN patients. The study includes all systemic lupus patients seen in Alexandria University Hospital since January 2004 for 6 months. Forty-three patients with SLE were presented to us by SLE, only 31 had LN and 22 were included in the study. The patients were classified randomly into 3 arms. All patients received steroid therapy plus from the beginning either Cyclophosphamide (CYP) [Group I, n=7], or Cyclosporine (CsA) [Group II, n=7], or Azathioprine (AZA) [Group III, n=8], Full history and examination were done. Laboratory investigations included routine and immunological studies of ANA, Anti-DNA, C3 and C4. Renal biopsy was done in all patients. After 6 months of follow up; Serum creatinine was stationary in CYP group from 2.2 +/- 1.1 to 2.1 +/- 1.7; while significantly decreased in CsA from 2.8+1.7 to 1.0 +/- 0.5 mg/dl. Moreover; while proteinuria decreased in CYP from 2.7 +/- 0.7 to 1.8 +/- 2.2; there was more pronounced decreased from 6.9 +/- 10.0 to 2.4 +/- 1.2 g/24 hr in CsA group despite very huge increase in glomerular filtration rate (GFR). 2 out 7 cases of CsA group; while 2 of 6 of CYP group did not show improvement. Moreover; 3 of 6 of CYP group and 1 of 6 of AZA group needed to be shifted to CsA group because of side effects and/or no response to CYP and showed good response. These patients were either class V or IV. However; only one case in this study with signs of acute CsA toxicity was reversed by monitoring the dose. In conclusion, CsA in this study proved to be superior over CYP in LN at least in the short term follow up; provided to be given with appropriate doses even if it is used in class IV, which was thought to be very responsive to CYP.

Cyclosporine (CsA)-induced nephrotoxicity can become a major obstacle to continuous use. The aim of this study was to optimize CsA dose to avoid its irreversible nephrotoxicity. Twenty-three Japanese patients with pediatric-onset systemic lupus erythematosus or idiopathic nephrotic syndrome, who were maintained in a stable condition by oral dosing of CsA microemulsion, were enrolled in this study. The patients were stratified into 3 groups; those with no, reversible, and irreversible nephrotoxicity, according to periodically performed renal pathohistological examinations. A higher concentration of CsA in blood (p=0.002-0.011) and a longer duration of CsA treatment (p=0.002) were risk factors for irreversible nephrotoxicity, and the cumulative CsA dose, the product of the maintenance dose and duration of CsA treatment, was predictive of nephrotoxicity (p=0.036). The maximum target blood concentration at 2 h post-dose, C(2), to avoid CsA-induced irreversible nephrotoxicity was 700 ng/ml, although the cumulative CsA dose of 4850 mg/kg would result in a 50% probability of nephrotoxicity.
