Recipient vessels from the head and neck region were histologically examined in 30 patients who had undergone extensive tumor resection necessitating microvascular tissue reconstruction. Past illnesses considered to be risk factors included hypertension, myocardial disease, lung disease, cirrhosis, diabetes, nephritis, as well as extensive nicotine and alcohol abuse. Blood vessels chosen for microsurgical anastomosis were exclusively examined histologically in this study. Patients undergoing microvascular surgery demonstrated vessel abnormalities in 93%. The frequency of dysplasia was higher in the arteries than in the veins (73% and 26%, respectively). Marked thickening of the blood vessel wall and severe exfoliation of the endothelial cells were observed in most arteries. Fibrodysplasia and exfoliated endothelial cells were more frequently observed in the recipient arteries than the graft arteries. Only slight thickening of the vessel wall and mild fibrodysplasia were seen in the veins. Two graft failures were correlated to technical errors rather than pre-existing vessel lesions. This study revealed that most patients undergoing microsurgery in the head and neck region demonstrate pre-existing damage in vessels, which generally hinders anastomosis. Although the study tried to identify fully the interrelationships between the extent of dysplasia, past medical history, preoperative therapy, risk factors and factors that cause free-graft failure, pre-existing changes in the recipient and graft vessels may cause technical difficulties and must be regarded as additional factors contributing to graft failure.

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.

While the relative incidence of serious nephrotoxicities in the population consuming nonsteroidal anti-inflammatory drugs (NSAIDs) is very low, the frequency of adverse events in patients at risk has considerably increased due to the rising popularity of the use of the drugs in recent years. Under normal conditions, NSAIDs have relatively little effect on the kidney because of low renal production of prostaglandins. However, in the presence of renal hypoperfusion in which local synthesis of vasodilator prostaglandins is increased to protect the glomerular hemodynamics and to maintain appropriate renal tubular transport of fluid and electrolytes, inhibition of prostaglandin synthesis by NSAIDs can lead to vasoconstrictive acute renal failure as well as fluid and electrolyte disorders such as sodium retention and resistance to diuretics, hyponatremia and hyperkalemia. Conditions that increase the risk for NSAID-induced nephrotoxicities include volume depletion from diuretics and other causes, edematous states such as congestive heart failure and cirrhosis of the liver, old age and underlying renal disease, especially in the presence of renal functional impairment. In addition, renal parenchymal diseases may develop in susceptible patients taking NSAIDs. These include acute tubulointerstitial nephritis, frequently associated with nephrotic syndrome, and chronic progressive renal disease, with or without renal papillary necrosis. Rare cases of vasculitis and glomerulonephritis have also been reported. Finally, NSAIDs may aggravate hypertension by interacting with antihypertensive drugs, especially with diuretics and beta-blockers. Withdrawal of NSAIDs in patients at risk can frequently reverse or improve the nephrotoxicities. It is recommended that physicians be aware of the clinical settings that increase the risk for NSAID-induced nephrotoxicities and take preventive or therapeutic measures accordingly.

The association between alpha1-antitrypsin (A1AT) deficiency and glomerulonephritis has only sporadically been reported, and mostly based upon autopsy findings, as opposed to the more frequent linkage between A1AT deficiency and lung emphysema with or without hepatic cirrhosis. The present case report describes a 30-year-old man with A1AT deficiency, without evidence of lung disease, who developed hepatic cirrhosis in early childhood and IgA glomerulonephritis and hypertension in adult life. The IgA nephritis followed an unusual course, with a sudden deterioration of the renal function, possibly induced by uncontrolled hypertension or the possible occurrence of vasculitis. After 6 months of hemodialysis, the patient successfully underwent living-related-donor kidney transplantation.

Glomerular IgA deposits were eluted from biopsied kidney tissues of patients with IgA nephritis and the antibody specificity was analyzed. The IgA was successfully eluted with combined use of citrate buffer and collagenase. The elution procedure did not attenuate antibody activity which was confirmed by the preliminary experiment that mouse IgA monoclonal anti-DNP antibody similarly treated did not cause any decline of antigen-binding ability. Because of the limited amounts ranging from 80-800 ng/ml, the eluted IgA did not react with respective lysates of the kidney tissues from which the IgA had derived. Moreover, kidney tissues from 9 biopsies yielded 5 micrograms/ml of IgA, when mixed together as source of IgA; nevertheless, the eluted IgA did not react with the kidney lysates, either. The eluted IgA, however, did react with several bacterial antigens, among which the 34-kDa antigen from Haemophilus influenzae (34-kDa H. influenzae) was most clearly detected with IgA eluted from pooled 10 kidney samples of IgA nephritis, which was confirming by Western blot analysis. The reactivity of the eluted IgA with the 34-kDa H. influenzae antigen was seen in 3/5 of IgA nephritis and 3/9 of non IgA nephritis patients with glomerular IgA deposits, respectively. The reactivity of serum IgA with the bacterial antigen was also investigated, which revealed that the serum IgA reacted with the 34-kDa antigen in 2/12 of IgA nephritis, 4/10 of liver cirrhosis patients and 3/10 of healthy control individuals, respectively. The surerum IgA from the IgA nephritis patients appeared to react with 34-kDa antigen more intensively than did healthy control IgAs. These results suggest that the 34-kDa H. influenzae plays an important role in the pathogenesis of at least certain IgA nephritis cases.

"The death rates at ages over 40 in Japan were analyzed using Japanese Vital Statistics for 1947-1988. Secular changes in the death rate and the age-specific death rate were analyzed according to sex and major causes of death. Twelve major causes of death were as follows: (1) malignant neoplasms, (2) heart disease, (3) cerebrovascular disease, (4) pneumonia and bronchitis, (5) accidents and adverse effects, (6) senility without mention of psychosis, (7) suicide, (8) chronic liver disease and cirrhosis, (9) nephritis, nephrotic syndrome and nephrosis, (10) hypertensive disease, (11) diabetes mellitus and (12) mental disorders.... The mean age at death increased 50 years [over] the last 38 years." (SUMMARY IN ENG)

This study examines the association between education and mortality from specific causes of death based on mortality records for 1996 and 1997, and 1996 population census data from the Region of Madrid (Spain). Poisson regression models were used to estimate the percentage increase in mortality associated with 1 year less education. The percentage increases in mortality from stomach cancer, lung, bladder and liver cancers, for aids, chronic obstructive pulmonary disease, pneumonia and influenza, and chronic liver disease and cirrhosis were higher in men than in women, whereas the percentage increases in mortality from colon cancer, diabetes mellitus, ischemic heart disease and nephritis, nephrosis and nephrotic syndrome were higher in women. The results found for some causes of death--lung cancer, ischemic heart disease, diabetes mellitus and chronic obstructive pulmonary disease--reflect the variations by educational level in the prevalence of lifestyle-related risk factors in men and women. Various hypotheses have been suggested for other causes of death, but it is not known why the magnitude of the association between education and mortality from some causes of death differs between men and women. Future studies of this subject may provide some clues as to the underlying mechanisms of this association.

Systemic lupus erythematosus (SLE) is frequently associated with ascites, but rarely without proteinuria. We report a 10-year-old girl with distended, non-tender abdomen with shifting dullness and no pitting edema in the lower legs before admission. Facial rash had appeared 1-2 weeks before admission and became more prominent 3 days prior to admission. Hypoalbuminemia with hypertriglycemia (but no proteinuria or diarrhea) was noticed. The antinuclear antibody titer was 1:2560 (speckle type) and the anti-double-stranded DNA was 1:160. Abdominal echo revealed no cirrhosis change or venous obstruction. Chest X-ray and electrocardiogram revealed no cardiomegaly or pericardial effusion. The serum prealbumin was low on admission day 5, but the liver function tests were within normal range. We deduced that the hypoalbuminemia in SLE without nephritis may be secondary to mesenteric vascular leakage. SLE may present with initial manifestation of painless massive ascites. Careful utilization of history taking, chest X-ray, electrocardiogram, cardiac and abdominal echo, urinary analysis and serum prealbumin is helpful in decision-making while assessing such patients.

We evaluated the utility of SDS-PAGE/Western blot and CE coupled with MS (CE-MS) for detection of urinary polypeptide biomarkers of renal disease in patients with IgA-associated glomerulonephritides. In a reference cohort of 402 patients with various renal disorders and 207 healthy controls, we defined CE-MS patterns of renal damage and IgA nephropathy (IgAN). In a blinded analysis of a separate cohort of patients with IgAN (n = 10), Henoch-Schoenlein purpura (HSP) with nephritis (n = 10), and IgA-associated glomerulonephritis due to hepatitis C virus (HCV)-induced cirrhosis (n = 9), and healthy controls (n = 12), we compared SDS-PAGE/Western blot and CE-MS against clinical urinalysis for detection of urinary proteins/polypeptides. Urinalysis indicated proteinuria for 50, 90, and 33% of patients, respectively, and for none of the healthy controls. SDS-PAGE/Western blot showed urinary polypeptides abnormality for 90, 80, and 67% of patients, respectively, and for none of the healthy controls. CE-MS indicated a Renal Damage Pattern in 80, 80, and 100 of patients, respectively, and in 17% of healthy controls, with the more specific IgAN Pattern in 90, 90, and 1%, respectively, and in none of the healthy controls. Based on differences in CE-MS patterns, the disease mechanisms may differ among various IgA-associated glomerulonephritides. These exploratory findings should be evaluated in a prospective study with contemporaneous renal biopsy and urinary testing. If validated, it may be feasible to adapt the CE-MS methodology to develop novel tests to detect renal injury at earlier stages, assess clinical manifestations, and monitor responses to therapy in patients with IgA-associated renal diseases.

We analyzed 137 cases of renal biopsies at the Department of Pathology from 2001 to 2007. The average age was 30.6 years (range, 13-72) for males and 32.9 years (range, 11-75) for females. The male to female ratio was 1.6: 1. The most common clinical syndromes for performing renal biopsy were nephrotic syndrome (81.6%) followed by asymptomatic urinary abnormalities (5.8%), nephritic syndrome (3.6%), hypertension (2.9%), chronic kidney disease (2.2%), acute renal failure (2.2%), cirrhosis (0.7%) and transplant rejection (0.7%). The major glomerular diseases in descending order of frequency were membranous glomerulonephritis (MGN; 42.3%), membranoproliferative glomerulonephritis (MPGN; 21.9%), minimal change disease (MCD; 10.2%), focal segmental glomerulosclerosis (FSGS; 8.0%), IgA nephropathy (2.9%), post infectious glomerulonephritis (GN) (2.2%), chronic GN (2.2%), tubulointerstitial nephritis (TIN; 1.5%), lupus nephritis (1.5%), focal proliferative GN (1.5%), Clq nephropathy (1.5%), amyloidosis (1.5%) and other minor form of glomerular diseases (2.8%). The pattern ofglomerulonephritis in our study is different from the reports of other developing countries. It could be due to various races and altered environmental condition. The information obtained from these results can be used as baseline data for making efficient research in Nepalese population in the future. The higher frequency of MGN and MPGN among Nepalese in comparison with other developing countries deserves further evaluation.
