Nodular regenerative hyperplasia is defined by hepatocellular nodules distributed throughout the liver in the absence of fibrous septa between the nodules. Most reports have been single cases so that the prevalence and clinical significance of nodular regenerative hyperplasia is uncertain. In this study, the hepatic histology of 2,500 consecutive autopsies was reviewed. A spectrum of nodular transformation was found with nodular regenerative hyperplasia present in 2.6% of autopsy livers and qualitatively similar but lesser degrees of nodular transformation in a further 10.2%. Nodular transformation was also seen in 47% of livers with
cirrhosis
and 69% with incomplete
cirrhosis
. Obliteration of many small portal veins was seen in all cases with nodular regenerative hyperplasia, but only 4.7% of these had evidence of portal hypertension. The prevalence of various clinical states was compared in nodular regenerative hyperplasia and in controls. The results confirm, extend and quantify the spectrum of associated diseases. Nodular regenerative hyperplasia occurs in 5.6% of individuals over age 80 and with increased frequency in patients with systemic arteritis, polymyalgia rheumatica, massive tumor infiltration and mineral oil deposition. Nodular regenerative hyperplasia appears to be the hepatic analogue of arterial and arteriolar
nephrosclerosis
. A new classification of nodular transformation is proposed that encompasses the spectrum of lesions described here and the previously defined entities of focal nodular hyperplasia, partial nodular transformation and "cirrhosis telangiectasia hepatis." The major conclusion is that nodular regenerative hyperplasia is a secondary and nonspecific tissue adaptation to heterogeneous distribution of blood flow and does not represent a specific entity.

Non-steroidal anti-inflammatory drugs (NSAIDs) may produce acute renal failure, papillary necrosis and interstitial nephritis. These adverse drug reactions are rare but have been reported in patients with congestive heart failure,
cirrhosis
, renal parenchymal disease, lupus nephritis and hypertension. All these conditions may be associated with hypovolaemia and an activated renin-angiotensin system, when renal blood flow and glomerular filtration depend on local renal prostaglandin biosynthesis. A severe impairment of renal function may occur when this synthesis is inhibited by NSAID treatment. It is possible that 1 in 100 of elderly patients have renal parenchymal disease, 1 in 100 arteriolar
nephrosclerosis
, 1 in 200 unilateral or bilateral renal artery stenosis and an unknown number suffer from atheroembolic renal disease. Fortunately, only a small proportion of 'at risk' patients given NSAIDs appear to develop renal failure. Perhaps bilateral renal disease or salt depletion are necessary factors? Whatever the explanation, NSAIDs should be used with caution in the elderly.

The renal pathologic features of 120 consecutively autopsied patients affected by acquired immunodeficiency syndrome was investigated by light microscopic analysis. Variously associated renal changes were found in 82 patients (68.3%). Glomerular changes were present in 25. The following diagnoses were made: mesangial glomerulonephritis (16 patients), defined by the presence of deposits in the mesangium and/or mesangial cell proliferation; membranous glomerulonephritis (4 patients), cirrhotic glomerulosclerosis (2 patients); and lupuslike glomerulonephritis (3 patients). Glomerular diseases seemed to be significantly associated with chronic hepatitis or
liver cirrhosis
. Interstitial inflammation was present in 19 cases: chronic pyelonephritis (2 patients), focal nephritis (5 patients), multiple cortical abscesses (7 patients), granulomatous nephritis (5 patients). Cryptococci were found in one and undetermined microorganisms in two cases of multiple cortical abscesses. Atypical mycobacteria were found in two cases of granulomatous nephritis. Mycotic infections were identified in another 6 patients, in whom they did not elicit any inflammatory response. It is worth stressing that, although various generalized infections are common in patients with acquired immunodeficiency syndrome, only cryptococci and atypical mycobacteria also frequently involve the kidney. Focal tubular necrosis was observed in 15 patients. Benign
nephrosclerosis
was the most common vascular change (27 patients). Changes recalling hemolyticuremic and localized intravascular coagulation were found in three and six patients, respectively. Our data, dealing with a European Caucasian population, considerably differ from those reported in North American literature, in as much as we found no cases of human immunodeficiency virus nephropathy. Conversely, immune-mediated glomerular diseases were frequent, in agreement with recent studies on renal biopsy specimens from AIDS patients with acquired immunodeficiency syndrome. This type of infections, supplies multiple sources of antigens that may stimulate immune complex formation and, therefore, glomerular diseases.

Heterocyclic indazole derivatives are claimed in patent WO2008138448 as inhibitors of the serum- and glucocorticoid-inducible-kinase 1 (SGK1) and drugs for the pharmacological treatment of SGK1-related diseases, such as diabetes, obesity, metabolic syndrome, systemic and pulmonary hypertension, cardiac fibrosis, hypertrophy and insufficiency, arteriosclerosis, glomerulosclerosis,
nephrosclerosis
, nephritis, nephropathy, deranged electrolyte excretion, fibrosing and inflammatory disease (e.g.,
liver cirrhosis
, lung fibrosis, rheumatism, arthrosis, Crohn s disease, chronic bronchitis, radiation fibrosis, sclerodermia, cystic fibrosis, scar formation and Alzheimer' disease), tumor growth, peptic ulcers and some disorders hitherto not conclusively shown to involve SGK1. Most of the claims are supported by the literature. SGK1 is ubiquitously expressed and its expression is stimulated by hyperglycemia, cell shrinkage, ischemia, glucocorticoids, mineralocorticoids and several inflammatory mediators including TGF-ss. SGK1 is activated by insulin and growth factors via the phosphatidylinositol-3-kinase pathway. SGK1 regulates ion channels (including ENaC, KCNE1/KCNQ1), carriers (including NCC, NHE3, SGLT1), Na(+)/K(+)-ATPase, enzymes (including glycogen-synthase-kinase-3) and transcription factors (including FOXO3a, ss-catenin, NF-kappaB). A gain-of-function SGK1 gene variant, carried by approximately 3 - 5% of Caucasians and approximately 10% of Africans, is associated with increased blood pressure, obesity and type 2 diabetes. In vitro and in vivo experiments suggested a critical role of SGK1 in renal fluid retention and hypertension, glucose-induced obesity, coagulation and increased matrix protein formation.

Evidence of immune stimulation has been noted in opiate dependent patients for many decades. Documented changes have included lymphadenopathy, round cell infiltration of the hepatic portal triads, diffuse peri-bronchitis, hyperglobulinaemia, lymphocytosis, monocytosis, systemic cytokine stimulation, and cytokine and chemokine activation within the neuraxis. A parallel literature describes an elevated list of chronic degenerative disease as common in such patients including neurodegenerative conditions, atherosclerosis,
nephrosclerosis
, hepatic fibrosis and
cirrhosis
, chronic obstructive and fibrotic lung disease, osteoporosis, chronic periodontitis, various cancers, hair greying, and stem cell suppression. All of these disorders are now known to have an important immunological role in their pathogenic pathways. The multisystem nature of these myriad changes strongly suggest that the ageing process itself is stimulated in these patients. The link between the immunostimulation on the one hand and the elevated and temporally advanced nature of the chronic degenerative diseases on the other appears not to have been made in the literature. Moreover as immunostimulation is also believed to be an important, potent and principal contributor to the ageing process it appears that experimental and studies of this putative link are warranted. Verification of such an hypothesis would also carry management implications for dose and duration of chronic pain and addiction treatment, pharmacotherapeutic selection, and novel treatments such as long term naltrexone implant therapy and heroin trials.

We report a 40-year-old man with end-stage renal disease due to IgA nephropathy who underwent deceased donor kidney transplantation. The donor was diagnosed to be brain-dead due to cerebral hemorrhage after her second liver transplantation for non-viral
liver cirrhosis
. Intraoperative 1-hour biopsy of the graft kidney revealed moderate global glomerular sclerosis (22%) and interstitial fibrosis (40%) consistent with underlying
nephrosclerosis
or calcineurin inhibitor nephrotoxicity. Although hemodialysis was needed until the graft began functioning several days after the kidney transplantation, the postoperative clinical course thereafter was uneventful and the graft functioned well with stable serum creatinine levels around 2.4 mg/dl at 6 monthspos toperatively.

Solid organ transplant recipients have an elevated incidence of thyroid cancer. We evaluated a wide range of potential risk factors in a cohort of 229 300 U.S. solid organ transplant recipients linked with 15 stage/regional cancer registries (1987-2012). Incidence rate ratios (IRRs) were adjusted for age, sex, race/ethnicity, transplanted organ, year of transplantation, and time since transplantation. Hazard ratios (HRs) for death and/or graft failure were adjusted for age, sex, race/ethnicity, transplanted organ, and year of transplantation. After transplantation, 356 thyroid cancers were diagnosed. Thyroid cancer incidence was 2.50-fold higher in transplant recipients than the general population (95% confidence interval [CI] 2.25-2.77). Among recipients of different organs, kidney recipients had the highest incidence of thyroid cancer (IRR = 1.26, 95% CI 1.03-1.53). Elevated thyroid cancer incidence was associated with cholestatic liver disease/
cirrhosis
as an indication for liver transplantation (IRR = 1.69, 95% CI 1.09-2.63), hypertensive
nephrosclerosis
as an indication for kidney transplantation (IRR = 1.41, 95% CI 1.03-1.94), and longer prior dialysis among kidney recipients (5+ vs. <1 year, IRR = 1.92, 95% CI 1.32-2.80; p-trend <0.01). Posttransplantation diagnosis of thyroid cancer was associated with modestly increased risk of death (HR = 1.33, 95% CI 1.02-1.73). Overall, our results suggest that end-stage organ disease and longer duration of dialysis may contribute to higher thyroid cancer incidence in transplant recipients.
