OBJECTIVES: Rheumatoid arthritis (RA) is a chronic inflammatory disease, characterized by polyarthritis and systemic manifestations. RA-fatigue is a significant problem and adds on disease burden. Sleep disturbance, depression, and disease activity are suggested contributing factors to RA-fatigue; however, their combined role did not examine before among Egyptian RA patients. The objective of the study was to investigate the presence of fatigue, sleep and mood disturbances in RA patients. Also, to evaluate the possible association of poor sleep, depression, and disease activity with RA-fatigue. METHODS: This cross-sectional study included 115 RA patients diagnosed according to the 2010 ACR-EULAR criteria and 46 age and sex matched controls. Fatigue using the Multidimensional Assessment of Fatigue-Global Fatigue Index, sleep using the Pittsburgh Sleep Quality Index and mood status using Beck Depression Inventory were assessed for all participants. RA disease activity was evaluated using disease activity score-28 joints. RESULTS: RA patients had higher mean fatigue, sleep disturbance, and depression scores (27.2±8.9, 6.4±3.6, and 12.8±7.3; respectively) than controls (22.7±7, 4.8±3, 7.8±5.9; respectively) (P.05). Poor sleep, depression and higher disease activity were significantly correlated with fatigue (r=0.4, r=0.65, r=0.55; respectively) (P.001). The three variables may explain up to 49.1% of the variation in fatigue on multiple regression analysis. CONCLUSION: Fatigue, poor sleep, and depression are more common in Egyptian patients with RA. A remarkably higher fatigue was associated with poor sleep, depression, and high disease activity, thus monitoring these silent comorbidities in clinical practice is required.

OBJECTIVES: The aim of the study was to estimate the crude prevalence rate (CPR) of compressive radiculopathies in Qena governorate/Egypt. PATIENTS AND METHODS: 10 areas in Qena governorate were selected by random sampling, involving 9303 inhabitants with 57.3% urban residents and 42.7% rural residence. Patients were diagnosed using a screening questionnaire for the diagnosis of cervical and lumbosacral radiculopathies. All positive cases were referred to Qena University Hospital where they underwent full neurological examination, neuro-imaging, and neurophysiological investigations. RESULTS: Out of 9303 inhabitants included in the study (1057 families), 49 cases were recruited positive on initial survey and 32 cases were confirmed after clinical examination, neuroimaging and neurophysiological examinations, giving a CPR of 10.1/1000 in those aged over 30 years. Compressive radiculopathy was more common in males than females (13 versus 6/1000) and in rural than urban populations (15 versus 7/1000). No cases were recruited below 30 years old. The highest age specific prevalence was at ≥60 years with a CPR of 26/1000. 11 cases had cervical radiculopathy while 21 cases had lumbosacral radiculopathy (CPR of 3.7 and 6.6/1000 respectively). The highest age specific CPR for males was earlier than females at 50-59 versus ≥60 years. CONCLUSION: The overall CPR of compressive radiculopathy in the general population in Qena governorate/Egypt is similar for cervical radiculopathy but higher for lumbosacral radiculopathy than a previous Egyptian study but mid-way compared to other countries.

Abstract OBJECTIVE: Previous animal work reported that hyperammonemia leads to opposing changes of GABAergic neurotransmission in terms of increase in the cerebellum and decrease in the cerebral cortex. In this study, we investigate GABAergic tone in the cerebellum in patients with hepatic encephalopathy (HE) at different stages of the disease and its relation to critical flicker frequency (CFF) and ataxia. METHODS: Cerebellar inhibition using transcranial magnetic stimulation was investigated in 15 patients with different stages of HE and 15 healthy controls. All patients were assessed using CFF and the score for assessment and rating of ataxia (SARA). RESULTS: Decreased cerebellar inhibition (CBI) was observed in manifest HE at interstimulus interval from 5 to 7 ms. However, the degree of CBI at 7 ms correlated significantly with disease severity measured with SARA and with CFF by trend. CONCLUSION: Reduced CBI in HE patients indicates affection of the cerebellar efferent pathway. The disease severity dependent increase of CBI magnitude supports the notion of disease stage dependent increase of GABAergic neurotransmission in Purkinje cells. SIGNIFICANCE: The results support previous animal experiments showing increase of GABA-ergic neurotransmission in the cerebellum and decrease in the motor cortex in HE.
