Retroperitoneal disorders associated with IgG4-related autoimmune pancreatitis

IgG4-related autoimmune pancreatitis is frequently accompanied by relevant lesions in the genitourinary tract and retroperitoneal organs, which cause various clinical problems, ranging from non-specific back pain or bladder outlet obstruction to renal failure. The diagnosis of IgG4-related retroperitoneal fibrosis requires a multidisciplinary approach, including serological tests, histological examination, imaging analysis, and susceptibility to steroid therapy. Radiological examinations are helpful to diagnose this condition, but surgical resection is occasionally unavoidable to exclude malignancy, particularly for patients with isolated retroperitoneal involvement. Steroid therapy is the treatment of choice for this condition, the same as for other manifestations of IgG4-related disease. For patients with severe ureteral obstruction, additional ureteral stenting needs to be considered prior to steroid therapy to preserve the renal function. Some papers have suggested that IgG4-related disease can affect male reproductive organs including the prostate and testis. IgG4-related prostatitis usually causes lower urinary tract symptoms, such as dysuria and pollakisuria. Patients sometimes state that corticosteroids given for IgG4-related disease at other sites relieve their lower urinary tract symptoms, which leads us to suspect prostatic involvement in this condition. Because of the limited number of publications available, further studies are warranted to better characterize IgG4-related disease in male reproductive organs.

[The comparative characteristic of immune status of males with bacterial inflammatory urogenital pathology of different etiology in the city of Orenburg]

The article discusses presence of typical characteristics of parameters of system immunity under gonococcal and nonspecific uretroprostatitis and diagnostic value of these indicators. The reliable differences of immunologic indicators in patients with gonorrhea are established as compared to patients with nonspecific bacterial uretroprostatitis. The study established in peripheral blood the reliable decrease of level of leukocytes, relative amount of monocytes, phagocyte index, functional reserve of leukocytes at the expense of spontaneous and stimulated NBT test, IgA, sIgA. On the contrary, the study detected increasing of level of IgM and lactoferrin in patients with gonorrhea as compared to corresponding indicators in patients nonspecific infections. Under gonorrhea, the largest deviation of indicators from standard values was established for lactoferrin. The detected differences of immunologic parameters can be used as differentiating markers of nonspecific and gonococcal uretroprostatitis and criteria of effectiveness of immune correction.

The anti-oxidant effects of ginger and cinnamon on spermatogenesis dys-function of diabetes rats

BACKGROUND

Diabetes rats have been linked to reproductive dysfunction and plant medicine has been shown to be effective in its treatment. Antioxidants have distinctive effects on spermatogenesis, sperm biology and oxidative stress, and changes in anti-oxidant capacity are considered to be involved in the pathogenesis of chronic diabetes mellitus. Ginger and cinnamon are strong anti-oxidants and have been shown to reduce oxidative stress in the long-term treatment of streptozotocin (STZ)-induced diabetes in animal models. The present study examined the influence of combined ginger and cinnamon on spermatogenesis in STZ-induced diabetes in male Wistar rats.

MATERIALS AND METHODS

Animals (n = 80) were allocated randomly into eight groups, 10 each: Group 1: Control rats given only 5cc Normal saline (0.9% NaCl) daily;Group2: rats received ginger (100mg/kg/rat) daily; Group 3: rats received cinnamon (75mg/kg) daily; Group 4: rats received ginger and cinnamon, (100mg/kg/rat ginger and 75mg/kg cinnamon) daily; Group 5: Diabetic control rats received only normal saline. Group 6: Diabetic rats received 100mg/kg/day ginger; Group 7: Diabetic rats received 75mg /kg/ day cinnamon; Group 8: Diabetic rats received ginger and cinnamon (100mg/kg/day and 75mg/kg /day). Diabetes was induced with 55 mg/kg, single intra-peritoneal injection of STZ in all groups. At the end of the experiment (56th day), blood samples were taken for determination of testosterone, LH,FSH, total anti-oxidant capacity, and levels of malondialdehyde, SOD, Catalase and GPX. All rats were euthanized, testes were dissected out and spermatozoa were collected from the epididymis for analysis.

RESULTS

Sperm numbers, percentages of sperm viability and motility, and total serum testosterone increased in ginger and cinnamon and combined ginger and cinnamon treated diabetic rats compared with control groups. Serum testosterone, LH and FSH were higher compared to control group and also serum anti-oxidants (TAC, SOD, GPX and catalase) all were increased at the end of treatment. Combined ginger and cinnamon showed more intense increase in all parameters compare to ginger and cinnamon alone. Most of the results were significant (P<0.05).

CONCLUSION

We concluded that combined ginger and cinnamon have significant beneficial effects on the sperm viability, motility, and serum total testosterone, LH,FSH and serum anti-oxidants' level and could be effective for maintaining healthy sperm parameters and male reproductive function in diabetics.

[Specific features of a change in some blood biochemical indicators in virus urogenital infections]

Analysis of blood biochemistry in cytomegalovirus, papillomavirus infections and herpes simplex virus showed a significant decrease in blood albumins, a significant rise in total protein, the percentage of alpha2-globulins, and an increase in the activity of ALAT, aldolase 1.6. This reflects the activity of inflammation, reveals hepatic toxic activity, and indicates renal dysfunction and externally asymptomatic active processes in the liver.

[Serum detection of human urogenital mycoplasma]

The authors compared the detection rate of DNA of urogenital Mycoplasmas (Ureaplasma spp. and M. hominis) in the urogenital tract (UGT) and serum samples by polymerase chain reaction. Testing the smears and serum samples from the same patients (n = 112) showed that Ureaplasma was more frequently detected in the UGT smears than in the serum samples. There was the same trend towards M. hominis although the difference was not so significant. Therefore, the detection of these microorganisms in UGT is of more informative value for diagnostic purposes. Examination of the serum samples for these purposes provides useful information in understanding the mechanisms of generalization of Mycoplasma infections and studying the routes and modes of spreading these bacteria in the organism.

[State of antioxidant defense and L-arginin-nitrogen oxide system in blood of patients with urogenital chlamydiosis]

The system L-arginine-nitrogen oxide plays a significant role in maintenance of the anti-infectious protection of an organism. A condition of the given system and activity of a enzymatic part of antiradical protection in the blood of patients with chlamydiosis has been studied. Obtained data specify an intensification of processes of an oxidizing way of recycling of arginine in an organism of patients. Substantial increase of NO-synthase activity and insignificant activity of arginase in the blood is revealed. The level of nitrite-anion in blood cells of patients authentically increases: 1.7 times in erythrocytes, and 1.4 times in lymphocytes. It is shown, that in patients with chlamydiosis glutathione system is intensified, that is evidenced by an increase glutathione-peroxidase activity and authentic increase of glutathione level. It is assummed that the established features of nitrogen oxide exchange play a significant role in formation of a pathological condition at urogenital chlamydia infections.

[Measurement of the reactive oxygen species and cytokines in the seminal plasma of leukocytospermic patients]

OBJECTIVES

To detect the levels of reactive oxygen species (ROS), superoxide dismutase(SOD) and interleukin 8(IL-8) in seminal plasma of infertile patients, and evaluate the possible relationship between those levels.

METHODS

Semen was collected from normal donors (15 cases), infertile men without infection (16 cases), and infertile men with infection (leukocytospermia, 11 cases). The routine analysis of semen was accomplished, and then the levels of IL-8, malondialdehyde (MDA), SOD, and white blood cell (WBC) were examined. The correlative analysis between the level of ROS and other parameters in these populations was made.

RESULTS

In leukocytospermic group, the levels of MDA, WBC, and IL-8 were higher than those in the other two groups (P < 0.001). Significantly positive correlation was observed between IL-8 and MDA (r = 0.852, P < 0.001) and between the levels of IL-8 and WBC.

CONCLUSIONS

These findings suggest that increased oxidative stress in patients with leukocytospermia may cause the increase of IL-8(r = 0.818, P < 0.01). The increased oxidative stress may be due to defect in ROS scavenging system.

Chlamydial antibodies in semen: search for "silent" chlamydial infections in asymptomatic andrological patients

The importance of a serological diagnostic workup in male genitourinary infections with Chlamydia trachomatis and its relevance for male infertility is still under debate. In a prospective study, antichlamydial serum and seminal plasma antibodies of 131 consecutive patients (mean age 31: 20-57) without evidence of acute urethritis and with negative urethral chlamydial culture were investigated. The antibody determination was carried out with a genus specific rELISA. In patients with positive seminal plasma IgA, chlamydial genome was evaluated by polymerase chain reaction (PCR). The results were associated with standard semen parameters according to evaluated WHO guidelines. Specific serum IgG antibodies were found in 51 patients (38.9%), IgA in 39 (29.7%); both antibodies were present in 25 patients (19%). Seminal plasma IgG was demonstrable in seven patients (5.3%), IgA in 26 (19.9%), and five patients were positive for both antibody classes (3.8%). Of the 26 men positive for specific seminal plasma IgA antibodies 12 did not demonstrate a serum antibody reaction. Only two patients with positive IgA titers in their seminal plasma showed a positive chlamydial genome reaction in PCR (8%). Men with antichlamydial seminal plasma IgA and/or IgG did not differ significantly in any of the standard semen sperm parameters from men testing negative for antibodies, with the exception of peroxidase positive leukocytes (p < 0.01), nor was there an association between any of the ejaculate parameters and any of the antibody titers. The data of about 40% antichlamydial serum antibody findings without a significant association with seminal plasma antibodies and no clinical signs of infection seem to reflect a history of urogenital infection. The unique presence of seminal plasma IgA in 12 of 26 cases may be caused by a local antibody response due to a "silent" infection. Thus, seminal plasma IgA was associated with signs of inflammation, whereas, there was no association with genome or pathogen demonstration. Therefore, it appears to be necessary to reevaluate genus-specific seminal plasma IgA antibodies with a species-specific microimmunofluorescence test and to compare these results with a genome screening using PCR or in situ hybridization.
