RESUMEN

BACKGROUND: Sarcoidosis is a multisystem granulomatous inflammatory disease which remains under-diagnosed in a tuberculosis endemic region such as Pakistan. RATIONALE: To determine the distribution, clinical characteristics, diagnostic and treatment modalities and the disease course in the Pakistani population. METHODS: A cross-sectional review of sarcoidosis patients from Jan-1,2010 to Dec-31,2019 was done. Multivariable logistic and cox-regression models were used to identify the independent risk-factors associated with disease relapse. Kaplan-Meier curves were used to assess the DFS. RESULTS: 222 patients, with mean age 44 ± 12 years, predominantly females (57.7%) and mean BMI 29 ± 6 were diagnosed sarcoidosis. Significant co-morbidities affected 36.5%, 90% were nonsmokers, and 50.3% belonged to moderate SES. Total 178 (80.2%) were symptomatic with 115 (51.8%) having multi-organ involvement. Stage-I radiological disease was predominant (52.5%). Histopathological diagnosis was obtained in 161 (72.5%) patients. Out of 113 mediastinal lymph-nodes, NNGI was present in 99, with highest yield in Station-07 (68.6%). Treatment was instituted in 108/178 (60.7%) symptomatic patients with steroids alone and in 26 (14.6%) with S+IS, with better clinical and radiological response duration in patients receiving steroid monotherapy (p-values=0.01 and 0.001,respectively, along with overall higher survival time (p-value = 0.04). Risk factors identified for relapse included high SES (AOR5.52;95%CI(1.10-28.40),0.04), steroid monotherapy (AOR0.22; 95%CI(0.10-0.87),0.03), symptomatic response after one year (AOR3.40; 95%CI(1.02-11.10),0.04), and radiological response duration (AOR1.10; 95%CI(1.05-1.20),0.04). CONCLUSION: Sarcoidosis is a dynamic disease with a variable clinical and geographical spectrum but good overall prognosis.

RESUMEN

CONTEXT: Malignant pleural effusion (MPE) is a common comorbid condition in advanced malignancies with variable survival. AIMS: The aim of this study was to predict the survival in patients with MPE undergoing indwelling pleural catheter (IPC) insertion. SETTINGS AND DESIGN: This was a cross-sectional study conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan. METHODS: One hundred and ten patients with MPE who underwent IPC insertion from January 2011 to December 2019 were reviewed. Kaplan-Meier method was used to determine the overall survival (OS) of the patient's cohort with respect to LENT score. STATISTICAL ANALYSIS USED: The IBM SPSS version 20 was used for statistical analysis. RESULTS: We retrospectively reviewed 110 patients who underwent IPC insertion for MPE, with a mean age of 49 ± 15 years. 76 (69.1%) patients were females, of which majority 59 (53.6%) had a primary diagnosis of breast cancer. The LENT score was used for risk stratification, and Kaplan-Meier survival curves were used to predict the OS. The proportion of patients with low-risk LENT score had 91%, 58%, and 29% survival, the moderate-risk group had 76%, 52%, and 14% survival, and in the high-risk group, 61%, 15%, and 0% patients survived at 1, 3, and 6 months, respectively. In addition, there was a statistically significant survival difference (P = 0.05) in patients who received chemotherapy pre- and post-IPC insertion. CONCLUSIONS: LENT score seems to be an easy and attainable tool, capable of predicting the survival of the patients with MPE quite accurately. It can be helpful in palliating the symptoms of patients with advanced malignancies by modifying the treatment strategies.

RESUMEN

BACKGROUND: The placement of indwelling pleural catheters (IPC) is an effective outpatient approach for the management of malignant pleural effusions (MPE). AIMS: The indications and outcome of IPC in patients with MPE. Risk stratifications, prevention and management of IPC-related complications. METHODS: We retrospectively reviewed the clinical data of patients with MPE who underwent IPC insertion from July 2011 to July 2019. The multivariable logistic regression model was used to identify the independent risk factors associated with IPC infection and the Kaplan-Meier method to determine the overall survival. RESULTS: A total of 102 patients underwent IPC insertion during the stipulated period and the mean age was 50.49 ± 14.36 years. Seventy-one (69.6%) were females. The indications were Trap Lung in 38 (37.3%), failed talc pleurodesis in 28 (27.5%) and as a primary intervention in 36 (35.3%). The infection rate was 25.5%, of which 65.4% patients had nosocomial infections. Post-IPC overall median survival time was 9.0 ± 2.50 weeks with highest in patients with trap lung (18 ± 1.50 weeks). In multivariable analysis, following variables were identified as a significant independent risk factor for IPC infection: Multiloculated MPE (AOR 2.80; 95%CI (1.00-9.93), 0.04), trap lung (AOR 7.57; 95%CI (1.39-41.25), 0.01), febrile neutropenia (FN) (AOR 28.55; 95%CI (4.23-19.74), 0.001), IPC domiciliary education (AOR 0.18; 95%CI (0.05-0.66), 0.001) and length of hospital stay (AOR 1.16; 95%CI (1.01-1.33), 0.03). CONCLUSION: IPC insertion is an effective management for MPE with reasonable survival benefits. Infection is the most common complication, of which mostly are nosocomial infections with higher incidence in multiloculated effusions, trap lung, FN and with lack of domiciliary IPC care education.
