The dental and periodontal health status of HD patients is comparable with healthy controls, but becomes worse with time on dialysis. Thus, oral health maintenance is of utmost importance in this patient group.

In this study, we retrospectively evaluated all attacks of diarrhoea in our renal transplant recipients that came to our medical attention between 1985 and 2000. Also, the clinical features of patients with diarrhoea were compared with the features of recipients without diarrhoea. We diagnosed 41 attacks of diarrhoea in 39 (12.6%) of 308 renal transplant recipients during this time period. An aetiology was detected in 33 (80.5%) of all diarrhoeal episodes and in seven (17.1%) of those the specific agent was diagnosed with the help of stool microscopy. The most frequent causes of diarrhoeal attacks were infectious agents (41.5%) and drugs (34%). Six (14.6%) episodes of diarrhoea were chronic and six were nosocomial. About two-thirds of diarrhoea developed within the late post-transplant period (>6 months). When recipients with diarrhoea were compared with those without diarrhoea, it was seen that diarrhoeal patients had significantly higher creatinine and significantly lower albumin levels when compared with the latter group (p < 0.05). Also, the frequency of antibiotic usage was significantly higher in diarrhoeal patients than in the control group (p < 0.05). Four (10.2%) patients with diarrhoea died despite institution of the appropriate therapy. Two of these deaths were primarily related to diarrhoea and the aetiological agent was Clostridium difficile in both these cases. During the 15-yr study period, 3.6% of all deaths and 5.1% of infection-related deaths in transplant recipients were secondary to diarrhoea. As a result, we observed that infections and drugs were the most frequent causes for diarrhoea in our series of renal transplant recipients. Also, diarrhoea was an important cause of mortality in this patient population.

In a retrospective evaluation, the incidence of systemic fungal infections (SFIs) in 296 kidney graft recipients admitted to our center between 1986 and 1999 was found to be 4%. Eighteen percent of 28 recipients transplanted in India and 8% of 12 recipients transplanted in Russia developed SFI. In contrast, SFI was encountered in only 2% of recipients transplanted at our center. The median time of diagnosis of SFI was 5 months after transplantation. The lungs and central nervous system were the most frequently affected sites. The most common etiologic agent was Aspergillus fumigatus (n = 7) but Candida spp. (n = 1), Rhizopus spp. (n = 1) and Cryptococcus neoformans (n = 1) were also encountered. In 2 patients, 2 different pathogens were isolated at the same time: A. fumigatus and Rhizopus spp. in 1 patient and Candida spp. and A. fumigatus in another. In order to determine predisposing factors for SFI, patients admitted immediately before and after those with SFI were used as controls: long-term hospitalization, long-term antibiotic use and post-transplant diabetes mellitus were found to be predisposing factors. Eight patients were treated with antifungal drugs and a good response to liposomal amphotericin B therapy was obtained in 3/5. Nine patients (75%) with SFI died. As SFIs are associated with a high mortality rate in renal transplant recipients, antifungal therapy, especially with liposomal amphotericin B, should be started whenever fungal infection is suspected, even before the results of microbiologic and/or histologic examinations are known.

QFT-G test results were more closely associated with TB risk factors than were positive TST results. Additionally, the QFT-G test was not affected by BCG vaccination. We concluded that QFT-G test is a more useful diagnostic method than TST for detecting LTBI in HD patients.

The presented study displayed important data about the epidemiology of primary glomerular diseases among adults in our country. The predominance of membranous nephropathy in contrast to other countries, in which the most frequent etiology is IgA nephropathy, seems to be due to differences in the indications for renal biopsy.
