Renal involvement in 204 cases with multiple myeloma admitted over a 10-year period to this tertiary care center in north India was retrospectively examined. Renal involvement occurred in 55 cases (27%); the vast majority of whom (94.5%) had presented with renal failure and 7.3% had nephrotic syndrome. The diagnosis of multiple myeloma was made after admission in 51 of the 55 (92.7%) cases. Oliguria was seen in 23.6% and two-third patients required dialysis. Factors precipitating renal failure were identified in 53% and included dehydration (33%), hypercalcemia (24%), nephrotoxic drugs (16%), sepsis (9%), recent surgery (5%) and contrast media (2%), Severe anemia, hypercalcemia, Bence Jones proteinuria and skeletal abnormalities were more frequent in those with renal involvement. Patients with renal involvement were more likely to have a high tumor burden. The myeloma was of light chain type in 68% of those with renal involvement whereas IgG myeloma was commonest (57%) in those without evidence of renal disease. Renal histology was studied in 27 cases with myeloma cast nephropathy seen in over 60%. Tubulointerstitial nephritis was seen in 14% cases, 11% had amyloidosis, 7% had acute tubular necrosis and 3.6% each had nodular glomerulosclerosis and plasma cell infiltration. In 8 cases (14.6%), renal biopsy provided the first clue to the diagnosis of myeloma. Renal function improved in 33% cases. Only 22% of patients on dialysis survived over 6 months. Median survival in those with renal involvement was only 4 months. Development of unexplained renal failure in an elderly individual with normal sized kidneys, in association with disproportionate anemia even in the absence of skeletal lesions should alert the physician to the diagnosis of multiple myeloma.

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare entity first described in 1975, affecting mainly young women and adolescents. We present a case of a 52-year-old female patient (one of the oldest in the literature) who complained of fever, anorexia, nausea, and vomiting. After she was admitted to our hospital, laboratory tests revealed tubular proteinuria, elevated erythrocyte sedimentation rate (ESR), anemia, and renal insufficiency (serum creatinine 4.2 mg/dL) with metabolic acidosis. Ophthalmologic examination revealed anterior uveitis (iritis) and renal biopsy showed acute tubulointerstitial nephritis. The diagnosis of TINU syndrome was established and the patient was treated with oral corticosteroids. All symptoms and ophthalmologic abnormalities disappeared after 6 weeks of treatment. Renal function also recovered completely and remained stable at follow-up. TINU syndrome should be considered in the differential diagnosis of unexplained tubulointerstitial nephritis, especially in the presence of ocular findings. Corticosteroid therapy is still controversial, but it helps in the quick resolution of renal and mainly eye abnormalities.

IgG4-related disease (IgG4RD) is a recent inflammatory process of supposed autoimmune etiology, which is characterized by elevated serum IgG4 levels, dense lymphoplasmacytic infiltration rich in IgG4-positive plasma cells and storiform fibrosis. Tubulointerstitial nephritis is the most common renal manifestation, with different degrees of kidney dysfunction and variable clinical findings. Herein, the authors describe a new case of IgG4 tubulointerstitial nephritis (IgG4TN), and discuss clinic and pathologic criteria. Male patient, 72 years-old, was admitted on hospital service with clinical complaint of asthenia, loss of strength, emaciation, and anosmia. Previous history included type 2 diabetes mellitus. Laboratorial data included normochromic anemia, proteinuria, and creatinine elevation. Bilateral kidney ultrassonography/computed tomography revealed a heterogenous parenchyma, with diffuse irregular dense zones, areas of fibrosis on upper poles, and hydronephrosys. Kidney biopsy showed a dense interstitial lymphoplasmacytic infiltrate, with more than 50 plasma cell per high power field, irregular areas of fibroblastic and collagenous fibrosis, focal tubulitis, and normal glomeruli. Immunofluorescence revealed mild granular deposition of C3c and IgG in the tubular basement membrane. Immunohistochemestry was positive for CD138, lambda and Kappa light chains, and IgG4 (around forty five IgG4 positive plasma cells per high power field). IgG4 serum level was increased. The diagnosis of IgG4TN was then established. The patient received corticotherapy and strict control of glycemia with insulin, with marked improvement of symptoms and creatinine levels.

Tubulointerstitial nephritis and uveitis (TINU) is a rare syndrome in which idiopathic interstitial nephritis coexists with chronic recurrent uveitis. This syndrome often represents systemic disorders such as arthralgia, rash, prolonged fever, anaemia and ocular symptoms that require medication including glucocorticoid administration. Recently, novel urinary biomarkers, such as kidney injury molecule-1, neutrophil gelatinase-associated lipocalin and liver-type fatty acid-binding protein, were shown to be associated with tubulointerstitial damage and were elevated in interstitial nephritis. We evaluated these urinary biomarkers in a case of TINU syndrome before and during treatment and found that their levels were elevated at onset and decreased during treatment, especially NGAL. We conclude that these urinary biomarkers are useful to evaluate and predict prognosis in interstitial nephritis.
