Objective: To determine frequency of different vascular access use in Incident hemodialysis (HD) patients and determine whether predialysis care in terms of timely advice for vascular access placement was better in the hands of nephrologist. Methods: A cross sectional study was conducted. Data was collected on the type of access used for first HD, including temporary Central venous catheters (CVC), permanent CVC (Permacath), arteriovenous fistula (AVF), or arteriovenous graft (AVG). In addition, information was also gathered if patients were aware of their renal disease and was followed by other physicians or nephrologist. Results: A total of 120 patients were enrolled in the study, 80% required CVC as their first access for HD (96/120 patients) out of which 74.2% were dialyzed through temporary catheter and 5.8% through Permacath. About 20% of patients were dialyzed through mature Arteriovenous (AV) access. Majority (95.8%) of patients were being followed by any health care provider. 68% of them were aware of their renal disease. About 55.8% were referred to nephrologist and 40% were followed by other physicians. About 83.5% of patients followed by nephrologist were advised AV access prior to commencing HD, compared to only 10.4% followed by other physicians (p<0.05). 24/61 (39.3%) patients that were advised AV access by both groups had timely made AV access and underwent HD by it. Conclusion: Very high incidence of temporary HD catheter was used in Incident HD patients. Moreover, pre dialysis care in terms of placement of AV access prior to initiating HD is better in the hands of nephrologist and patients should be timely referred to nephrologist especially when they have Stage 4 chronic kidney disease (CKD).
Objective: Pulmonary hypertension (PH) has been described in hemodialysis (HD) patients and has been associated with increased morbidity and mortality. Our objective was to determine the prevalence of pulmonary hypertension in patients on regular hemodialysis. Methods: This cross sectional study was conducted in Department of Nephrology, Liaquat National Hospital Karachi from April 2013 to March 2014. Eighty patients of end stage renal disease (ESRD), on maintenance hemodialysis (HD); underwent Trans thoracic Echocardiography were selected. Systolic pulmonary arterial pressure (SPAP) was recorded. Pulmonary hypertension was defined as, pulmonary artery pressure (PAP) greater than 30 mm Hg at rest. Pulmonary hypertension was further divided into mild (PAP b/w 30-45mmHg), moderate (PAP b/w 45-65mmHg) and severe pulmonary hypertension (PAP > 65mmHg). The effect of different vascular accesses, age, gender, dialysis vintage on the development of pulmonary hypertension was observed. Results: Out of 80 patients, 45 patients (56%) had pulmonary hypertension (PH); 25(55.5%) had moderate, 13(29%) had mild, and 7 (15.5%) patients had severe pulmonary hypertension (PH). Pulmonary hypertension was present in 41(60%) patients with AVF, 3(27%) patients with tunnel cuffed catheter and 1 patient had AV bridge graft. Pulmonary hypertension was more common in females; present in 28 females (67%) and 17 males (45%), that was statistically significant (p<0.05). Mean duration of hemodialysis in (months) of patients with PH was 20.93 ± 12 vs. 10.29 ±10 in patients without PH (p<0.05). Age had no relation to development of PH. Conclusion: ESRD patients on HD have strong tendency to develop PH. Our study demonstrated that PH is more common among females. Duration of hemodialysis and AV access has strong relation to the development of PH.
IntroductionThere is a great scarcity of literature in Pakistan investigating the proportion of end stage renal disease (ESRD) patients undergoing hemodialysis (HD) who meet the recommended kidney diseases outcome quality initiative (K/DOQI) guidelines for serum calcium (Ca), phosphorus (P), calcium phosphorus product (Ca x P) and parathyroid hormone (PTH) levels. Our study aimed to determine frequencies of patients who met the K/DOQI targets for these minerals at a tertiary care hospital's dialysis unit.Methods111 ESRD patients on maintenance HD were selected from a tertiary care hospital. Serum Ca and P were assayed on chemistry analyser. PTH was measured through electrochemiluminescence sandwich method. Data were compared with K/DOQI targets and analysed using SPSS-21.ResultsThe mean age of patients was 55.85 years (SD ± 13.95). Gender distribution was almost equal with 49.5% males and 50.5% females. The patients had mean corrected serum Calcium 9.12 ± 0.64 mg/dL, Phosphorus 4.57 ± 1.54 mg/dL and Parathyroid hormone 333.8 ± 278.4 pg/mL. The patients had achieved K/DOQI target ranges of Ca, P, PTH, Ca x P product and all 4 criteria in 63.1%, 47.6%, 38.7%, 84.7% and 10.8% respectively.ConclusionMajority of patients on maintenance HD at our institution did not achieve the recommended K/DOQI target ranges. Further studies pertaining to the Asian subcontinent will prove resourceful for comparison of mineral metabolism and dialysis outcome of ESRD patients.
Background and Objective:Systemic lupus erythematosis (SLE) is an inflammatory disorder associated with significant morbidity and mortality. Kidneys are frequently affected in SLE and various stages of lupus nephritis have been identified based on severity of the disease. Treatment varies with the staging and correct diagnosis is essential for timely intervention as it can have significant impact on morbidity and mortality. The objective of the study was to determine whether laboratory parameters of lupus nephritis (LN); including urinalysis, serum creatinine (S. Cr) and 24 hours urine protein can accurately predict histologic staging of the disease.Methods:This retrospective study was conducted in department of Nephrology, Liaquat National Hospital Karachi from January 2012 to December 2014. Fifty one patients of SLE who underwent renal biopsy were selected. Patients, urinalysis at the time of renal biopsy, serum creatinine and 24 hours urine collection for protein were noted. All patients renal biopsy was read by the same pathologist. Patients were clinically staged based on these parameters and their histologic staging based on biopsy findings were compared, to see their correlation. Data was analyzed using SPSS version 17. Chi-square test was used to analyze categorical data and p<0.05 was considered significant. Cohen’s kappa (κ) analysis was used to examine the agreement by comparing lupus nephritis staging done by laboratory and histological ground. P value <0.05 indicates that agreement was unlikely due to chance alone.Results:Among 51 patients analyzed, 37 patients were females (72.5%) and 14 patients were males (27.5%) with mean age of 32.51 + 16.91 years. In stage II, kappa (κ) of 0.304 represented fair strength of agreement and a p value of 0.012 (p<0.05)which was statistically significant. In stage III, kappa was 0.209 indicating none to slight agreement and a p value of 0.131 (p>0.05). In stage IV, kappa (κ) was 0.141 (slight agreement)and p value 0.301 (p>0.05) in stage V; kappa (κ) of 0.030 represented poor agreement and a p value of 0.828 (p>0.05).Conclusion:Staging of lupus nephritis done on basis of laboratory findings did not correlate well with underlying histological staging. Therefore, renal biopsy is an essential tool in approach to lupus nephritis in order to provide timely and appropriate treatment to patients.
