Systemic Lupus Erythematosus (SLE) is an acquired, multiorgan, autoimmune disease. Clinical presentation is extremely variable and heterogeneous. It has been shown that SLE itself is an independent risk factor for developing both arterial and venous thrombotic events since SLE patients have an Odds Ratio (OR) for thrombosis that varies depending on the clinical and laboratory characteristics of each study cohort. The risk of developing a thrombotic event is higher in this setting than in the general population and may further increase when associated with other risk factors, or in the presence of inherited or acquired pro-thrombotic abnormalities, or trigger events. In particular, a striking increase in the number of thrombotic events was observed when SLE was associated with antiphospholipid antibodies (aPL). The presence of aPLs has been described in about 50% of SLE patients, while about 20% of antiphospholipid syndrome (APS) patients have SLE. While APS patients (with or without an autoimmune disease) have been widely studied in the last years, fewer studies are available for SLE patients and thrombosis in the absence of APS. Although the available literature undoubtedly shows that SLE patients have a greater prevalence of thrombotic events as compared to healthy subjects, it is difficult to obtain a definite result from these studies because in some cases the study cohort was too small, in others it is due to the varied characteristics of the study population, or because of the different (and very copious) laboratory assays and methods that were used. When an SLE patient develops a thrombotic event, it is of great clinical relevance since it is potentially life-threatening. Moreover, it worsens the quality of life and is a clinical challenge for the clinician.

Background: IgA nephropathy (IgAN) is a microcosm of glomerular lesions. Some histologic lesions are irreversible and progress toward obliteration of glomerular capillaries. Others are acute inflammatory processes potentially susceptible to reversal by means of immunosuppressive therapies. Methods: The effects of a combined schedule of steroids and mycophenolate mofetil (MMF) was prospectively examined in a subset of IgAN patients with acute inflammatory histologic changes associated with proteinuria (mean 2,400 mg/day, range 1,130-5,250), hematuria (76 red cells per high-power microscopic field, range 30-100) and renal failure (serum creatinine 1.6 mg/dL, range 1.2-2.9). Patients had diffuse mesangial proliferation with at least 10% florid crescents, mild to moderate degrees of glomerular sclerosis and interstitial changes, and both mesangial and capillary deposition of immunoreactants at immunofluorescence. Treatment consisted of 3 pulses of methylprednisolone (15 mg/kg) followed by oral prednisone (0.8 mg/ kg body weight, tapered until discontinuation within 4 months) and MMF 2 g for 6 months. Results: Serum creatinine, proteinuria and microscopic hematuria significantly dropped at 6 months compared with baseline values (p=0.01) and remained lower at the end of follow-up 51 months (range 24-90) later (p<0.01, for proteinuria and hematuria; p=0.08, for serum creatinine). Conclusion: Therapy with steroids and MMF may be considered in a subset of IgAN patients with florid glomerular changes, functional impairment and major urinary abnormalities, to prevent subsequent progression toward renal failure.

This is the report of the clinical case of a patient who presents the association of a JAK-2 positive chronic myeloproliferative neoplasia to a subsequent 5q- myelodysplastic syndrome, developed after about 14 years from the first diagnosis. Patient’s symptoms had rapidly worsened, and she became transfusion-dependent. Therapy with low-dose Lenalidomide quickly reduced the splenomegaly, and completely brought white cells counts, haemoglobin and platelets back to normal.  After more than one year from start, blood cell count is still normal. As far as we know this is the first case of an effective treatment with Lenalidomide reported in this clinical setting.
