ABSTRACT

Therapeutic plasma exchanges (TPE) is considered as one of the treatment modalities that is used in systemic autoimmune diseases. This study aimed to describe the early and late effect of TPE in patients with systemic lupus erythematosus (SLE) and antineutrophil cytoplasmic antibody-associated vasculitis (AAV) presented with acute kidney injury (AKI). Retrospective study comprised patients with SLE and AAV with AKI seen between January 2000 and June 2014 at King Faisal Specialist Hospital and Research Center in Riyadh. All patients underwent TPE. Retrospectively, all patients were assessed for early and late renal outcome at 12- month and 24-month intervals. Renal outcome was assessed according to serum creatinine level, glomerular filtration rate, active urine sediment, and proteinuria. P <0.05 was considered significant. A total of 68 patients were included, 58 patients (51 females) had SLE and 10 patients (7 females) had AAV completed TPE. All patients had active disease and had AKI. At the first 12 months, 18 patients (17 SLE and 1 AAV) showed complete response and 14 patients had partial response while 22 patients did not show therapeutic benefit. The nonresponders (22 patients) entered the late assessment interval (24 months) without any therapeutic response. Statistically, there was no significant difference between the patient's response to TPE at the first and second assessment intervals and the baseline serum creatinine level. TPE might be an alternative rescue treatment in lupus nephritis with AKI.

ABSTRACT

OBJECTIVE: To investigate the effects of diclofenac alone or when combined with alpha-tocopherol on the oxidative activity of polymorphonuclear leukocytes (PMNs) in healthy and osteoarthritic (OA) patients. METHODS: The study was carried out at the College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, over the period 1999 to 2000. Twelve healthy controls and 12 osteoarthritic patients were recruited to the study. Twelve healthy controls and osteoarthritic patients were given diclofenac 50 mg thrice daily orally, initially for 5 days then alpha-tocopherol at 200 mg thrice daily orally, was added for another 5 days. Blood samples were drawn before the start of the study (pre-treatment) and at 5 days following treatment with diclofenac alone and 10 days following treatment with diclofenac and alpha-tocopherol. Chemiluminescence (CL) response was measured for whole blood and isolated polymorphonuclear leukocytes (PMNs) on all samples. RESULTS: Diclofenac enhanced CL response of whole blood and of PMNs of healthy controls when stimulated with phorbol myristate acetate (PMA) and opsonized zymosan (OPZ). Co-treatment with alpha-tocopherol resulted in no appreciable change in the CL response of whole blood when stimulated with PMA or OPZ but a further significant enhancement of CL response of isolated PMNs when these cells were stimulated by either PMA or OPZ. In osteoarthritic patients, diclofenac alone and when combined with alpha-tocopherol showed no significant change in CL response of whole blood. The CL response of PMNs from OA patients was decreased by diclofenac alone. However, this inhibitory effect was not observed when alpha-tocopherol was used together with diclofenac. CONCLUSION: The effect of diclofenac alone or in combination with alpha-tocopherol did not produce a consistent effect on the CL response of whole blood or isolated PMNs of healthy or osteoarthritic patients.

ABSTRACT

OBJECTIVE: To find out the effect of combining allopurinol with non-steroidal anti-inflammatory drugs on carrageenan-induced rat paw edema. METHODS: The study was carried out at the College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, over the period 1999 to 2000. Male wistar rats were randomly divided into 12-16 rats in each group. Edema was induced by subplantar injection of 0.1 ml of carrageenan (10 mg/ml) and the resulting edema volume was measured by plethysmograph, 3 hours after the injections. Saline of 0.9% (0.1 ml/100 g) was administered to the first group serving as control. The second and third groups received variable concentration of allopurinol (12.5, 25, 50 mg/kg) and tenoxicam (0.0625, 0.125, 0.25 mg/kg) 30 minutes before carrageenan injection. The fourth group received a combination of tenoxicam and allopurinol. Similar procedures were carried out with respect to diclofenac at 1.25, 2.5, 5.0 mg/kg and indomethacin at 0.25, 0.5, 1.0 mg/kg. The activities of the drugs were expressed as percentage inhibition of edema. RESULTS: Pre-treatment of the rats with the 4 drugs individually resulted in dose-dependent reduction of volume of paw edema. The combination of allopurinol and diclofenac acted synergistically to reduce edema. A similar synergistic action was obtained when allopurinol was combined with indomethacin. By contrast, tenoxicam-allopurinol combination resulted in antagonistic action and produced an effect on edema, which was less than their individual inhibitory action. CONCLUSION: Combining allopurinol with either diclofenac or indomethacin produced synergistic inhibitory action on rat's paw edema. However, tenoxicam, when combined with allopurinol, produced antagonism.

ABSTRACT

OBJECTIVE: To estimate the prevalence of musculoskeletal (MSK) pain in Al-Qaseem province in central Saudi Arabia. METHODS: Over a period of 18 months extending from September 1993 through to the end of February 1995, a house-to-house survey was conducted in Al-Qaseem province and included 5,894 adults asking regarding musculoskeletal pain. RESULTS: We obtained a response from 5,823 (98.8%), 2,667 (45.8%) men, and 3,156 (54.2%) women. The mean age was 34.14 +/- 15.16 years. Musculoskeletal pain was reported by 1,477 (25.4%), 762 (13.1%) men and 715 (12.3%) women. Musculoskeletal pain was significantly correlated with age (r =0.454), married status (r=0.238), unemployment (r=0.122), lower educational attainment (r=0.347), frequent attendance at local doctor (r=0.703), consumption of medications for pain (r =0.551), and change in ability to work (r=0.492). We found no association with sex or body mass index. CONCLUSION: Musculoskeletal pain, although common in the community, is less prevalent than reported from Western countries, but has similar socio-medical consequences.

ABSTRACT

OBJECTIVE: The aim of this study was to estimate the prevalence of back pain in the adult population of Al-Qaseem Central Province, Kingdom of Saudi Arabia and to find associated features and factors. METHODS: A house-to-house survey covering 1,000 household in the towns and villages of Al-Qaseem province was carried out over a period of 18 months extending from September 1993 until the end of February 1995. A total of 5,894 adults, aged 16 years and above, were questioned by trained staff regarding back pain, and the demographic data in addition to general, medical and social history. RESULTS: A response was obtained in 5,743 (97.4%). Their mean age was 34.14 15.16 (range 16-99). Back pain was reported by 1,081 (18.8%), wherein 499 (8.8%) were men, and 574 (10%) were women. Back pain was more prevalent in married (23.3%) individuals than unmarried (6.4%). Adjusted odds ratio (OR) for back pain in married individuals was 1.88 (95% confidence intervals [CI] 1.49-2.37). Back pain was strongly correlated with age (correlation coefficient = 0.378 P < 0.01). It also showed significant correlation with weight and height, depression, family history of back pain, change in work ability, frequency of attendance at local doctor, use of medication and lower education level. The association with body mass index became evident only after comparing the heaviest 20th percentile to the lightest (OR 1.335 [95% CI, 1.279-1.402]). Certain occupational status (unemployed, farmers, professional workers and housewives) were associated with back pain. CONCLUSION: Back pain was relatively common in this largely unindustrialized community although its prevalence is lower than reported from some western countries.

ABSTRACT

OBJECTIVE: Although systemic lupus erythematosus of varying severity has been seen in our clinics, there is no information regarding the prevalence of the disease among Saudi nationals. We conducted this study to determine the prevalence of systemic lupus erythematosus in Al-Qaseem region of the Kingdom of Saudi Arabia. METHODS: A community survey of towns and villages in the Al-Qaseem area of central Saudi Arabia was conducted in 3 phases to determine the prevalence of systemic lupus erythematosus in the region. RESULTS: Of the 10,372 studied, 2 cases of systemic lupus erythematosus were identified using the criteria set for the diagnosis of systemic lupus erythematosus by the American College of Rheumatology. Based on that, the prevalence of systemic lupus erythematosus was estimated to be 19.28 per 100,000 population in the region. CONCLUSION: The estimated prevalence of systemic lupus erythematosus in Al-Qaseem area is similar to that found in western countries.
