[Diagnosis and therapy of anemia in general practice]. / Diagnostik und Therapie der Anämie in der Praxis.

Anemia is a common problem in family medicine and therefore frequently investigated in general practice. Anemias are classified according to mean corpuscular volume (MCV) and reticulocyte count. An algorithm for the evaluation of the cause contains patients history and laboratory analysis including reticulocyte count, serum ferritin and CRP, serum vitamin B12, serum or erythrocyte folate and serum creatinine. Therewith most anemias in general practice can be explained. The most important types of anemia, e.g. iron deficiency anemia, are discussed as well as aspects of diagnosis and therapy. Iron deficiency anemia is often diagnosed together with other types of anemia, such as e.g. anemia of chronic disease. Particular aspects of anemia in the elderly as well as renal anemia are discussed.

[An uncommon case of lupus]. / Ein aussergewöhnlicher Fall von Lupus.

A 44-year-old patient was referred with weight loss of some 6 kg in two months, weakness and diarrhoea. According to the criteria of the American College of Rheumatology (ACR), systemic lupus erythematosus (SLE) was diagnosed: photodermatosis, nephropathy, and pancytopenia with positive antinuclear antibodies and antibodies against native DNA. In addition, adrenal failure was diagnosed with hyponatraemia, relapsing fever, low baseline cortisol and impaired response to ACTH stimulation. Clinical features of SLE may obscure signs of adrenal insufficiency, and hence, diagnosis is jeopardized. SLE combined with Addition's disease is rare. In some patients with both disorders, antiphospholipid antibodies, as found in our patient, are considered responsible for the development of Addison's disease. Possible pathogenetic mechanisms such as adrenal haemorrhage or (micro)thrombosis are discussed. The patient's condition significantly improved under steroid therapy. The progression of renal insufficiency (histology: mesangioproliferative glomerulonephritis), however, required additional immunosuppression with cyclophosphamide.
