The levels of autoantibody classes IgG, IgM, IgA, IgD against renal antigens together with CH50, C3, C4, lysozyme, and phagocytic activity against Staphylococcus aureus SG 511 and E. coli 014 were determined in serum samples from 3 groups of patients with chronic pyelonephritis. Increased levels of IgG and IgD were found in patients with severely impaired renal function while increased levels of IgM and IgD correlated with disease activity. C3 levels were increased with enhanced activity and C4 and lysozyme levels with reduced renal function and distinct activity. The value of these findings is discussed and the clinical usefulness of the determination of levels of IgM, IgD, C3, C4, and lysozyme is pointed out.

Forty-seven adults with urinary tract infection (UTI), 9 with recent acute pyelonephritis and 38 with previous renal infection, were investigated for the presence of autoantibodies to Tamm-Horsfall protein (THP). All patients except 6 had or had had vesicoureteric reflux (VUR). In patients with recent acute pyelonephritis, only IgA antibodies were significantly elevated. Among the patients with previous UTI, more than 6 months before the time of testing, a graded response was found for IgG and IgM specific antibodies, with the lowest value in those with renal damage and elevated serum creatinine and the highest in those with a normal X-ray. A negative correlation was found between IgG antibodies to THP and elevated serum creatinine (r = -0.76, P less than 0.02). No significant correlation was found between VUR itself and antibodies to THP. A low IgG antibody level to THP in patients with a history of previous UTI seems to be a useful indicator of renal scarring. Possible immunologic mechanisms behind the low antibody level and the renal damage are discussed.

The role of antibodies to Tamm-Horsfall protein in the diagnosis of acute pyelonephritis was studied. Antibodies to Tamm-Horsfall protein were also determined in a group of normal subjects. Patients with acute pyelonephritis were divided into subgroups according to the concurrent presence of vesicoureteral reflux or nephrolithiasis. No statistically significant differences (p > 0.05) were observed for any class of antibodies (IgG, IgA and IgM) between the groups of healthy subjects and patients with acute pyelonephritis, regardless of the presence or absence of vesicoureteral reflux or nephrolithiasis. Values for different antibody classes showed that IgM antibodies were the most abundant in all the groups examined. A difference in the values of IgM relative to IgA and IgG antibodies was found to be statistically significant in the patient group only (p < 0.05). In patients with vesicoureteral reflux, there was no statistically significant difference (p > 0.05) between the values of IgM and of other antibody classes. In these patients, however, the highest values of all the three antibody classes were obtained, although these differences were also not statistically significant (p > 0.05). The results pointed to the need of further studies of the role of antibodies to Tamm-Horsfall protein in the diagnosis and pathogenesis of tubulointerstitial nephritis.

We report a case of selective IgA deficiency in a girl who received a successful renal transplant from a donor with normal serum IgA level. Although the recipient serum was negative for anti-IgA antibody, the donor kidney was washed with a sufficient volume of perfusate and the amount of corticosteroid given to the patient immediately after the revascularization was increased to twice the normal dose. Serum complement level transiently decreased, but recovered during the first week after surgery. Although the patient suffered from acute pyelonephritis of the graft during the fourth month, there has been no evidence of infection thereafter.

The authors examined 150 patients with pronounced arterial hypertension: 73 with essential hypertension, 42 with chronic glomerulonephritis, 26 with chronic pyelonephritis and 10 with diabetic glomerulosclerosis. In addition to conventional tests, measurements were made of renin activity, levels of plasma aldosterone and hydrocortisone, IgA, IgG, IgM, CIC. A significant rise in concentrations of aldosterone, hydrocortisone against a significant fall in those of plasma renin were registered in all the patients irrespective of the disease. Significant differences between the groups by the renin profile, aldosterone and hydrocortisone levels were absent. It is suggested that changes in the hormonal spectrum and immunological indices are independent of renal affections in hypertension, while involvement of renin-angiotensin-aldosterone system in hypertension stabilization has no nosological specificity. The pattern of the immunity shifts evidences for their important pathogenetic role in maintenance and progression of arterial hypertension.

Humoral and cellular immunity and data on biopsy tissue inoculation were evaluated for 72 patients with morphologically confirmed pyelonephritis. Cellular immunity was judged by lymphocyte rosette-test. T-lymphocyte subpopulation was counted in absolute numbers. No case of the biopsy bacterial contamination was shown bacteriologically. A complement C3 component was obtained in amounts similar to those in the controls. In remission IgA tended to a significant increase which (in IgM fall) continues in the disease aggravation. T-lymphocytes (total, active and suppressors) reduced in number, the changes arising in the remission with further intensification in a pyelonephritis exacerbation. Basing on the evidence obtained it is inferred that a significant suppression of cellular immunity, particularly T-suppressors, agrees with the idea of pyelonephritis as genetically determined, infection-mediated immune inflammation initially involving the medullary layer and urinary mucosa. The disease is characterized by defects in local immunity and changes in the density of receptors to the agent antigens. The predisposition came to action in disorders of urodynamics consequent to obstruction or ureteral hypotonicity of nonobstructive nature.

The aim of this study was to determine antibodies to Tamm-Horsfall protein subunits in patients with acute pyelonephritis. The protein subunits used in this determination were prepared by chemical treatment of Tamm-Horsfall protein isolated from the urine of healthy individuals. Values for IgG and IgA were significantly higher (p < 0.05 and p < 0.01 respectively) in patients than in healthy persons, while IgM class antibodies were significantly higher only in the test performed with subunits obtained with 8.3 mol/l acetic acid (THP-A) (p < 0.05). Values for all three classes determined in the test with THP-A were significantly higher in patients with vesicoureteral reflux than in patients with normal radiological findings (p < 0.05). Antibodies to Tamm-Horsfall protein subunits isolated from the urine of patients with acute pyelonephritis should also be determined.

As many as 296 patients with acute pyelonephritis were evaluated for parameters characterizing their immunological status. The results were as follows: decreased levels of T-lymphocytes, T-helpers, and immunoregulatory index in 42%, 87% and 72% respectively. In normal indices of spontaneous test with nitroblue tetrazolium stimulated below the norm was in 71% of cases. A study involving the use of monoclonal antibodies revealed no changes in the EK-cells counts, while their functional activity was decreased in 52% of patients. The functional activity of lymphocytes in the reaction of blast transformation in response to phytohemagglutinin and PWM was running down in 83% and 75% of cases respectively. With high levels of blood serum IgA and IgM the number of the immune complexes was noted to be on the increases in 68% of patients. The level of spontaneous productions of IL-1 was normal whereas that of IL-2 elevated, with the stimulated production of there mediators in AP patients being significantly below the norm.

51 patients with urolithiasis complicated by pyelonephritis in the active phase of inflammation were studied for the condition of local immunity by determining the urine content of secretory immunoglobulin A (SIgA) under conditions of combined treatment with making use of phlogenzyme, a drug of II-generation systemic enzymotherapy (SE). Recordable in this patients population was a marked increase in the urine level of SIgA. Incorporation in a combined treatment of phlogenzyme results in normalizing the status of the urinary system local immunity. Evidence has been obtained on the lack of parallelism in the dynamics between the serum IgA content and urine concentration of SIgA, which fact suggests independence of local immunity. Our theory is that an appreciable increase in the urine level of SIgA in patients with urolithiasis concurrent with pyelonephritis may have an important part to play in the genesis of nephrolithiasis.

The aim of this study was to examine the incidence of different renal lesions in rheumatoid arthritis (RA) and to determine their relationships with the type of previous drug therapy and with the specific features of immune disorders. Ninety four patients, 84 (89.9%) females and 10 (10.6%) males) with RA whose mean age was 45.2 +/- 11.9 years and duration of the disease 7.5 +/- 6.5 years were examined. Most of them had degrees 2 and 3 PA (62.7 and 24.4%, respectively). Systemic manifestations were encountered in 60 (63.8%) patients. Eighty one patients took nonsteroidal antiinflammatory drugs (NSAID) continuously: 18 patients for a year, 32 for 5 years, 14 for 6 to 10 years, and 17 for over 10 years. All the patients underwent clinical, laboratory, and instrumental study of partial functions of the kidney. Immunological study involved solid-phase immunoassay of IgA and IgM rheumatoid factor, von Willebrand factor antigens (WF:Ag), C-reactive protein. The serum concentrations were measured by the Mancini method. Changes in urinalysis and/or signs of decreased glomerular and tubular functions were found in 69 (73.%) patients, 25 (26.6%) had arterial hypertension. Tubular dysfunctions were more common [31 (32.9%) patients]. Signs of early renal failure were detected in 20 (21.2%) patients. There were no cases of acute renal failure. Amyloidosis, glomerulonephritis, pyelonephritis were diagnosed in 5 (5.3%), 16 (17%), and 13 (13.8%) patients, respectively. The above renal lesions were concurrent in some patients. Renal lesion correlated with the progression and severity of RA, the presence of systemic manifestations, and age. There was no relationship of both 5- and 10-year use of NSAID to the symptoms of renal disease. The use of these drugs for over 10 years was concurrent with the signs of chronic renal failure and arterial hypertension. Analyzing immunological disorders showed an association of increased erythrocytic sedimentation rates and WF:Ag with amyloidosis, that of higher IgA concentrations with proteinuria and tubular dysfunctions. It is concluded that renal lesion is common in RA, there is a predominance of tubular interstitial changes. In rare cases nephropathy is characterized by a benign course and fails to result in uremia. The symptoms of renal diseases are largely associated with RA progression and severity and the patients' age. Prolonged continuous use of NSAID may contribute to the development of renal failure. Different immune mechanisms are involved in the pathogenesis of glomerular and tubular nephropathy in RA.
