ABSTRACT
Result: Mean age of the subjects was 57 ± 13 years of 56.25% were male and 43.75% were female. 69 patients completed the study. The Empirical Distribution Function (EDF) of NP group was dominant over control and NT group indicating a positive effect of NT on non-diabetic CKD at 10% level of significance. In the subgroup analysis a significant effect was observed in the cases of patients receiving NP with baseline eGFR more than 45 ml/min. The mean increase in eGFR readings over six months was 8.15 units higher in the NP group than in the control group. The two-sided p-values of the t-test, the Wilcoxon test and the Kolmogorov-Smirnov test were 0.0496, 0.0316 and 0.0354, respectively. Thus, all the three tests reject the hypothesis of identical changes in eGFR at the 5% level. In subjects with bicarbonate more than 22 mg/dl, the mean increase in eGFR over six months was 10.86 units higher in the NP group than in the control group indicating NP has a positive effect on increasing eGFR over 6 months, in patients without the presence of any metabolic acidosis. The two-sided p-vales of the t-test, the Wilcoxon test and the Kolmogorov-Smirnov test were 0.0325, 0.0205 and 0.1495, respectively. Thus, two of the three tests reject the hypothesis of identical changes in eGFR at the 5% level which clearly indicates that NP had better efficacy than other groups. Conclusion: N-acetyl cysteine along with pyridoxine may be a useful intervention along with a low protein diet in retarding progression of CKD in the nondiabetic population in early CKD.
ABSTRACT
Objective: To study the clinical profile and assess the utility of the procedures performed for the diagnosis of extra" pulmonary TB (EPTB) in HIV patients. Design: Prospective observational study of HIV patients suspected to have EPTB. Results: Two hundred and thirty HIV-infected patients were enrolled over 18 months. Of them, 87 cases had active TB, 60 (69%) of whom were of EPTB. Major presenting symptoms were fever (93.3%), weight loss (80%) and cough (61.6%). The most common site of active EPTB was the abdomen (70%), which could be detected due to routine use of abdominal ultrasonography, followed by CT scans in inconclusive cases. Peripheral lymph node (22% ), pleura (15%), CNS involvement (3%) and one case each of psoas abscess and mediastinal lymphadeopathy were the other extra-pulmonary sites seen. Diagnosis of peripheral lymph node and pleural TB was based on cytological and mycobacterial examinations. Direct smear examinations were positive for AFB in 11 of 24 samples and mycobacterial cultures were positive in five of 18 samples. The median CD4 ceH count in our HIV-EPTB cases was 126 cells/ml3 (IQR-79.5-205.75). There was no statistical difference in the baseline CD4 ceH counts in patients with PTB vs EPTB (p-0.70), single vs multiple extra-pulmonary site involvement (p-0.57), and AFB positive vs AFB negative EPTB cases (p-0.51). Conclusions: EPTB is the most common form of TB in HIV patients with low CD4 cell counts. Fever, weight loss and cough are common presenting symptoms of EPTB. Routine abdominal ultrasonography followed by an abdominal CT scan in inconclusive cases can significantly increase the detection of abdominal TB.
