An unusual case of a patient with Goodpasture's disease presenting with hemoptysis, severe iron deficiency anemia and microscopic hematuria and proteinuria is described. Both circulating and tissue anti-glomerular basement membrane (GBM) antibodies were present, and renal function remained normal throughout. Immunosuppressive therapy was given for subclinical pulmonary hemorrhage with successful resolution of anemia and disappearance of the circulating anti-GBM antibody. Nine months after presentation he developed nephrotic range proteinuria and a repeat renal biopsy revealed membranous glomerulonephritis with no evidence of his original disease. Both the Goodpasture's associated HLA-DR2 and the membranous associated HLA-DR3 class II antigens were present. The association of antibody mediated and immune complex glomerulonephritis is discussed. The simultaneous presence of HLA-DR2 and HLA-DR3 may predispose to this association.

A 30-year-old HIV-infected intravenous drug user presented with sepsis, acute renal failure, oedema, proteinuria and iron deficiency anaemia. After extensive investigation, a diagnosis of reactive systemic AA (amyloid, serum amyloid A protein) amyloidosis was made on the basis of renal, gastric and duodenal biopsies.

Coeliac sprue (CS) may occur in association with immune complex-mediated diseases, including IgA nephropathy, dermatitis herpetiformis and thyroiditis. An association of CS with membranoproliferative glomerulonephritis (MPGN) type 1 is rare, with only two prior cases reported. Here we describe a 45-year-old man with no prior medical history who presented initially with microhaematuria, subnephrotic proteinuria and hypocomplementaemia. A renal biopsy revealed MPGN type 1 with negative serologic workup for secondary causes. The patient was treated conservatively with angiotensin-converting enzyme inhibitors. Several months later, he developed daily non-bloody diarrhoea and was found to have worsening hypoalbuminaemia, hypophosphataemia and severe iron deficiency anaemia. A diagnosis of CS was established based on elevated tTGA (IgA anti-tissue transglutaminase) antibody and positive IgA antiendomysial antibody titres. Proteinuria resolved completely following the initiation of a gluten-free diet, without the use of immunosuppressive therapy and despite tapering of angiotensin-converting enzyme inhibitor. This case illustrates that CS-associated MPGN may precede overt clinical evidence of coeliac disease and may respond to gluten-free diet, without resort to immunosuppressive therapy.

Although anemia frequently occurs in poststreptococcal acute glomerulonephritis (PSAGN), severe anemia is rare. We report severe normocytic, normochromic anemia (hematocrit, 19.8%) in PSAGN in a 6-year-old girl with edema, macrohematuria, and proteinuria for 1 month. The potential causes of severe anemia found in this case were: 1) longer duration of massive hematuria from onset of macrohemauria to treatment, 2) a level of erythropoietin much lower than that in cases of iron deficiency anemia, and 3) hemodilution. We speculate that these factors combined to cause an unusual case of severe anemia in PSAGN.

Multiple extraintestinal diseases are present in 0.3- 4.5 % of inflammatory bowel disease patients. A 39-year-old woman was admitted with a 3 months history of cervicalgia with functional incapacity, asthenia, tibio-tarsal bilateral arthritis and bloody diarrhoea. She had ferropenic anemia, SR-120 mm, creatinine clearance-42 mL/min, proteinuria-1.2 g/24h. Colonoscopy with biopsy showed active ulcerative rectossigmoiditis. She had bilateral sacroileitis more pronounced at the right side which was suggestive of ankylosing spondylitis. HLA B27 was positive. Because of colestasis, colangio-MRI and CPRE were done and were suggestive of primary sclerosing colangitis. Renal disease was interpreted as an analgesic nephropathy versus glomerulonephritis associated with ulcerative colitis. Cardiac ecodoppler showed pericardial thickening with a thin pericardial effusion. Full improvement of gastrointestinal complaints was observed with 5-ASA topic enemas, sulfassalazine, corticosteroids and azathioprine and full remission of ankylosing spondylitis with adalimumab. This case illustrates extraintestinal wide involvement as the initial presentation of ulcerative colitis, remarking its systemic nature.

Anemia, iron deficiency anemia (IDA), and iron deficiency (ID) are highly prevalent in renal transplant recipients (RTR). Anemia is associated with poor outcome, but the role of ID is unknown. Therefore, we aimed to investigate the association of ID, irrespective of anemia, with all-cause mortality in RTR. Cox regression analyses were used to investigate prospective associations. In 700 RTR, prevalences of anemia, IDA, and ID were 34%, 13%, and 30%, respectively. During follow-up for 3.1 (2.7-3.9) years, 81 (12%) RTR died. In univariable analysis, anemia [HR, 1.72 (95%CI: 1.11-2.66), P = 0.02], IDA [2.44 (1.48-4.01), P < 0.001], and ID [2.04 (1.31-3.16), P = 0.001] were all associated with all-cause mortality. In multivariable analysis, the association of anemia with mortality became weaker after adjustment for ID [1.52 (0.97-2.39), P = 0.07] and disappeared after adjustment for proteinuria and eGFR [1.09 (0.67-1.78), P = 0.73]. The association of IDA with mortality attenuated after adjustment for potential confounders. In contrast, the association of ID with mortality remained independent of potential confounders, including anemia [1.77 (1.13-2.78), P = 0.01]. In conclusion, ID is highly prevalent among RTR and is associated with an increased risk of mortality, independent of anemia. As ID is a modifiable factor, correction of ID could be a target to improve survival.

Mantadakis E, Zikidou P, Tsouvala E, Thomaidis S, Chatzimichael A. Severe iron deficiency anemia and anasarca edema due to excessive cow`s milk intake. Turk J Pediatr 2019; 61: 102-106. The authors describe a 13-month-old girl who presented with progressively worsening anasarca edema that developed over the last three weeks along with increasing fatigue. Over the last several months she was consuming progressively increasing amounts of fresh cow`s milk. Laboratory examinations on admission showed severe microcytic and hypochromic anemia (hemoglobin 3.8 g/dl) and hypoferritenemia indicative of iron deficiency, while urinalyses showed no proteinuria. The child was transfused with 13ml/kg packed red blood cells and approximately 2g/kg intravenous albumin. On the second and fourth hospital days, she received 100 mg of iron sucrose intravenously that she tolerated well. Eight months after the described events, she is healthy with normal hemoglobin for age, while she has no laboratory evidence of cow`s milk protein allergy. Pediatricians should be aware of the association of severe iron deficiency anemia (IDA) and anasarca edema, and should screen infants in their practice for anemia at the age of 12 months or sooner, if risk factors are present.
