ABSTRACT
Collapsing glomerulopathy (CG) is a proliferative podocytopathy, increasingly recognized in a variety of disease conditions. We report a case of CG in a 16-year-old boy with IgA nephropathy (IgAN) who presented with acute kidney injury, marked proteinuria and hypertension following a short period of anabolic steroid use. Although CG has been associated with long-term anabolic steroid use among body builders, there is no data on the effect of anabolic steroid use in persons with underlying renal disease like IgAN. We postulate that development of CG in our patient could be temporally linked to intake of body-building steroids along with a predisposing background renal disease of IgAN.
ABSTRACT
Immunoglobulin G4-related disease (IgG4-RD) is an emerging clinicopathological entity. Renal involvement is dominated by tubulointerstitial nephritis (TIN) with IgG4-positive plasma cells and fibrosis. IgG4-RD commonly affects middle-aged to elderly men with accompanying extra-renal lesions such as sialadenitis, lymphadenopathy, or type 1 autoimmune pancreatitis, all of which respond favorably to corticosteroid therapy. The disease burden of IgG4-related kidney disease (IgG4-RKD) in India remains largely underestimated. We report a case of IgG4-RKD manifesting as TIN associated with interstitial pulmonary disease, illustrating typical clinico-pathologic, serologic, immuno-histochemical, and ultrastructural features of this condition. In view of potential amelioration of renal dysfunction with appropriate therapy, the need for awareness of this condition and early diagnosis is highlighted.
ABSTRACT
Mitochondrial cytopathies (MC) are a rare heterogenous group of disorders with frequent multisystem involvement including uncommon renal manifestations. Acute kidney injury (AKI) as the primary manifestation of MC is extremely rare. Here, we report a case of recurrent episodic AKI in an adult male who was subsequently diagnosed to have mitochondrial disease.
ABSTRACT
The diets of 19 galactosaemic patients were assessed for calcium and phosphorous intake. Despite the use of infant soya formula or calcium-supplemented soya milk the reference nutrient intake (RNI) for calcium was only met in 26% of the group; all patients met > 100% of the RNI for phosphorous. The regular assessment of the diets of galactosaemia patients is recommended as the milk-free nature of the diet can lead to an inadequate calcium intake. Lactose-free calcium supplements should be prescribed if the diet alone is inadequate.
