Factors affecting the use of peritoneal dialysis among the ESRD population in India: a single-center study.

OBJECTIVES: Factors such as limited health-care budget allotment and poor accessibility of the majority of the population to hemodialysis (HD) facilities should favor the use of peritoneal dialysis (PD) in India. However, only 6% of end-stage renal disease patients undergoing dialysis in India are on PD. We undertook this prospective study to evaluate various factors that could contribute to this low rate of use of PD at a tertiary-care state-run hospital in Northern India. METHODS: All the patients who entered our HD or PD program from August 2001 to December 2003 were interviewed using a preset questionnaire. The questionnaire recorded their basic disease and comorbidity, social and demographic characteristics, awareness of the various modalities of renal replacement therapy (RRT), and the reasons for choosing their present modality of therapy. Treating nephrologists were also interviewed with respect to the factors that, in their opinion, were responsible for the limited use of PD at our institute. RESULTS: In total, 342 patients on HD, 66 patients on PD, and 24 nephrologists were interviewed. The rate of PD use was 16.2%. Mean age of patients on HD and PD was 34.6 +/- 11.8 years and 62.9 +/- 10.3 years respectively (p < 0.0001). The incidence of diabetes mellitus and coronary artery disease in the HD and PD populations was 2.5% and 62.5%, and 9.1% and 46.7% respectively (p < 0.0001 for both). Only 30.4% of patients on HD were aware of PD as a modality of RRT and 83.6% of them found PD to be expensive, 65.4% had low enthusiasm toward a domiciliary therapy such as PD, and 61.5% were not recommended PD by their nephrologist. Only 5 (7.6%) patients were initiated on PD directly, the remaining 61 patients were shifted from HD after a mean duration on HD of 185.3 +/- 15.4 days: 67.1% were shifted due to poor tolerance of HD, 29.4% were advised to shift to PD because of comorbidity and vascular access problems, and only 3.3% took up PD because of the independent lifestyle it offered. None of the interviewed nephrologists routinely discussed PD in predialysis counseling. They found financial constraints (100%), lack of patient enthusiasm (100%), doubtful patient compliance (83.2%), and lack of an organized PD program (79.2%) to be the main factors limiting more widespread use of PD at our institute. CONCLUSIONS: Peritoneal dialysis is an underused modality of RRT at our institute. The patients who are taken up for PD at our institute are elderly and have a higher incidence of other comorbid conditions, such as diabetes mellitus and coronary artery disease. Also, most patients who switch to PD do so due to their unsuitability for HD rather than by their own choice. The factors contributing to this low rate of use of PD are ignorance of PD, increased cost of therapy, low enthusiasm toward domiciliary therapy, and lack of adequate infrastructure for PD at our institute. Effective predialysis counseling, reduction in the cost of the therapy, and development of an adequate infrastructure can increase the rate of use of PD.     

An unusual case of mediastinal mass due to Fonsecaea pedrosoi.

Phaeohyphomycosis is a disease caused by dematiaceous fungi. Here, the first culture-proven case of mediastinal mass due to Fonsecaea pedrosoi is reported. The patient was a 40-yr-old male who had presented with history of dyspnoea and dysphagia. Computed tomography of the chest disclosed a mediastinal mass. Cultures of a specimen from the mediastinum grew Fonsecaea pedrosoi. The patient received amphotericin B and itraconazole and showed a remarkable recovery. Repeat computed tomography revealed a reduction in the mediastinal mass. The case highlights the need for a high degree of clinical suspicion and appropriate histopathological and mycological examination of clinical specimens.     

Menstrual-Linked Asthma

This study was conducted to determine the occurrence of menstrual-linked asthma (MLA) in India in 100 consecutive female asthmatics in the reproductive age group. The patients were required to respond to a questionnaire concerning the relationship between their asthma and the menstrual cycle. Twenty-three patients had subjective perception of deterioration in symptoms of asthma in relation to the menstrual cycle. Ten patients from both groups were also required to maintain a daily peak expiratory flow rate (PEFR) diary for 2 consecutive menstrual cycles. The mean total duration of illness in patients with MLA was significantly longer than in patients without cyclic exacerbation. Cough and breathlessness were also significantly more severe as was the disease. This was evidenced by the more frequent emergency room visits and hospitalizations in these patients. Menstrual-linked worsening of asthma was most common in the premenstrual week (17 patients). In 8 of these 17 patients, this phenomenon continued to occur during the menstrual week also. Interestingly, 1 patient complained of deterioration of asthma 2 days after menstruation was over. Such an observation is yet to be recorded. Fourteen patients reported an increase in symptoms with almost every cycle while 3 had worsening related to specific season only. Sixteen patients often required extra medication during the premenstrual and/or menstrual weeks. A significant association was also observed between severity of premenstrual syndrome and MLA. The mean PEFR values over 2 cycles revealed a significant fall in the morning as well as evening values in the premenstrual and menstrual weeks as compared to the midcycle week in patients with MLA. This fall was maximal in the premenstrual week. Such a fall was not observed in asthmatics without menstrual exacerbation of symptoms. MLA was detected in about a fourth of the female asthmatics in India and it appears to represent a more severe form of the disease. This study also documented that MLA was associated with an increase in airway resistance and was not simply due to an increased perception of symptoms during the premenstrual or menstrual weeks.     

Duodenogastric reflux after choledochoduodenostomy

Duodenogastric reflux (DGR) has been implicated in several disease processes. The present study was carried out to document the incidence and evaluate the clinical significance of DGR after choledochoduodenostomy (CDD). A total of 13 patients who had undergone cholecystectomy with a standard side-to-side CDD for choledocholithiasis or chronic pancreatitis were studied by symptom evaluation, scintigraphy, endoscopy, and gastric mucosal histology at least 6 months after surgery. The scintigraphic findings were then compared with those of 10 patients who had undergone cholecystectomy alone. Only two patients (15%) had mild dyspeptic symptoms. The incidence of DGR after CDD was 69% compared to 20% in the cholecystectomy alone group (P < 0.05). In the majority of patients the DGR was only mild to moderate and the severity correlated well with the degree of endoscopic gastritis, but not with the clinical symptoms or histological findings. These results indicate that while CDD is associated with a high incidence of DGR, its occurrence does not produce significant clinical symptoms.     

Rheumatic fever: clinical profile of the initial attack in India

The clinical profile of acute rheumatic fever in developing countries is frequently reported to differ from that in developed countries. This probably arose because a distinction was not made between the manifestations of the initial attack and those of a recurrence. Here, we report the patterns of presentation and clinical features of 100 cases of carefully determined initial attacks of rheumatic fever. As many as half the patients had carditis, and, of these, 50% exhibited congestive cardiac failure. This high incidence arises because in developing countries with limited health-care facilities patients continue to be physically active during the long pre-admission period. The study confirms that the clinical profile of the initial attack of rheumatic fever in developing countries is in most respects not unlike that in developed countries.
