Many pharmacologic agents affect the kidney, but special attention should be paid to four classes: aminoglycoside antibiotics, radiocontrast agents, ACE inhibitors, and NSAIDs. Iatrogenic complications associated with these agents include acute renal failure, acute interstitial nephritis, and prerenal failure, which are frequently reversible with early diagnosis.

Renal diseases as glomerulonephritis, diabetic nephropathy, interstitial nephritis (e.g. analgetic nephropathy) or systemic disease with renal involvement are responsible for renal hypertension. High blood pressure remains the most important factor for progression of chronic renal failure. On the other hand, effective anti-hypertensive therapy results in inhibition of progression. Clinical and experimental studies show a renoprotective effect of ACE inhibitors due to lowering of systemic blood pressure, reduction of glomerular capillary pressure, reduction of proteinuria and antiproliferative effects.

We describe the frist reported case in Switzerland of HIV-associated nephropathy (HIVAN). HIVAN shows a typical combination of clinical findings: black race, proteinuria, large hyper-echogenic kidneys, normal blood pressure, positive HIV serology and no autoantibodies. The histologic findings are typical: focal segmental glomerulosclerosis of the collapsing variant, often with marked interstitial nephritis. The disease normally appears before AIDS symptoms develop and follows a very aggressive course to end-stage renal disease. Therapy consists of a combination of nucleoside reverse transcriptase and proteinase inhibitors, ACE inhibitors, and possibly steroids. In end-stage renal disease patients can be managed by haemodialysis, continuous ambulatory peritoneal dialysis (CAPD) or kidney transplantation.

A 49-year-old woman, who had been diagnosed as sarcoidosis based on bilateral hilar lymphadenopathy and lung biopsy, presented increased serum creatinine and calcium concentrations. Renal biopsy showed the presence of interstitial nephritis with non-caseating epithelioid granuloma and focal membranous transformation. Therapy with prednisolone was effective in normalizing serum creatinine, serum calcium, serum angiotensin converting enzyme, and urine beta2 microglobulin, but these abnormalities reappeared after rapid withdrawal of prednisolone. This is a rare case of sarcoidosis manifested by both membranous nephropathy and granulomatous interstitial nephritis, and indicates the necessity of long-term treatment of corticosteroid.

Chronic renal failure (CRF) is a complex phenotype, which results from the underlying kidney disease and superimposing environmental and genetic factors. The aim of the study was to evaluate the role of angiotensin converting enzyme gene Pst 1 polymorphism in the development and/or progression of CRF. 247 family trios (patients with CRF and both parents): 120 with primary chronic glomerulonephritis, 80 with interstitial nephritis and 47 with diabetic nephropathy were examined, and transmission/disequilibrium test (TDT) was used to evaluate allele transmission from heterozygous parents to affected off-spring. No significant deviation from random transmission of the examined ACE gene Pst 1 alleles was observed, as well as no impact of this marker on the rate of progression of chronic renal failure.

Human immunodeficiency virus-associated nephropathy (HIVAN) is a distinct clinico-pathological syndrome that occurs almost exclusively in black patients with an AIDS defining diagnosis. It is characterized by rapidly progressive renal failure with a severe nephrotic syndrome. The renal biopsy typically shows a collapsing glomerular sclerosis and variable tubulo-interstitial nephritis. The pathogenesis most likely involves infection of renal tubular and epithelial cells with HIV. The use of ACE-inhibitors and steroids may slow down the progression to end-stage renal failure. With the introduction of highly active anti-retroviral therapy, HIVAN may now be treated effectively although clinical data are so far limited to case-reports.

Autoimmune pancreatitis is a rare form of pancreatitis characterized by responsiveness to steroid therapy and an often relapsing disease course. The mainstay of therapy is oral corticotherapy. Associations of interstitial nephritis with various autoimmune disorders have been described. We hereby report the case of a 69-year-old Caucasian man with a 2-year history of autoimmune pancreatitis, who presented with impairment of kidney function, proteinuria, and hypertension. Renal histopathology showed severe diffuse interstitial nephritis. With oral prednisone and ACE inhibitor therapy, complete recovery of kidney function was not achieved and proteinuria persisted. Therefore, mycophenolate mofetil was initiated. After 8 weeks, serum creatinine decreased, and a nearly complete and sustained resolution of proteinuria was seen, while tapering oral steroid doses. With autoreactive T cells playing a major role in the pathogenesis of both diseases, a common etiology of pancreatitis and interstitial nephritis can be assumed, and the beneficial effects of an inhibitor of lymphocyte proliferation, such as mycophenolate mofetil, can be explained. We infer from our case that mycophenolate mofetil can be effective in the control of simultaneous autoimmune pancreatitis and interstitial nephritis.

All types of acute kidney injury (AKI) (functional /pre-renal, parenchymal/intra-renal, obstructive/post-renal) result in a sharp drop of the glomerular filtration rate, with variable reversibility according to the initial cause. In one case out of five, drug intake can be related to the onset of AKI. Antibiotics, analgesics and nonsteroidal anti-inflammatory drugs, angiotensin converting enzyme inhibitors and angiotensin II receptor antagonists are the agents mostly involved, as well as iodinated radio-contrast agents. Mechanisms are often complex: toxic cellular effect directed on a nephron segment (tubular necrosis) associated or not with intraglomerular hemodynamic changes, or immune process leading to acute tubule-interstitial nephritis. Each underlying risk factor (age > 60 year, cardiac or hepatic failure, hypertension, diabetes, intra-vascular volume depletion, preexisting or unknown chronic kidney disease) must be taken into consideration by the prescribing physician because it reduces the chance of functional recovery and worsens the renal and the overall prognosis. A pre-renal additional component is often present and avoidable thanks to a strict hemodynamic monitoring. The present article summarizes some recent physiopathological aspects of AKI and makes the link between clinical situations and currently prescribed drugs. Lessons from the radio-contrast induced nephropathy are examined by taking into account prevention aspects and risk factors screening. An effective collaboration between the general practitioner and the nephrologist would benefit in optimizing the treatment of difficult cases.

Sarcoidosis is an inflammatory disease that affects mostly the lungs and lymph glands. Renal involvement is rare and especially vasculitis. We report a case who presented an acute kidney failure and had sarcoidosis with vasculitis and nodular splenic involvement. A 35-year-old woman presenting a Lofgren syndrome was hospitalized for acute renal failure with cervical lymphadenopathy without other clinical findings. Laboratory data disclosed elevated angiotensin converting enzyme serum level. Abdominal ultrasound showed a multinodular spleen. Renal histology revealed granulomatous interstitial nephritis with necrotizing vasculitis. Outcome was favorable after the institution of high dose corticosteroids along with cyclophosphamide. Renal involvement is rare in sarcoidosis. However, the diagnostic delay should be avoided to improve the outcome.
