Comparative Study of Infliximab Therapy and Methotrexate Monotherapy to Improve the Clinical Effect in Rheumatoid Arthritis Patients.

Objective We examined whether infliximab (IFX) therapy was more effective than methotrexate (MTX) monotherapy to achieve an improvement in depressive states in Rheumatoid Arthritis (RA) patients. Methods We examined 152 RA patients (72 IFX patients and 80 MTX patients). We conducted an open-label cohort study to evaluate the disease activity of RA (Simplified Disease Activity Index; SDAI), depressive states (Hamilton Rating Scale for Depression; HAM-D), Activity of Daily Living (ADL) (modified Health Assessment Questionnaire; mHAQ) and Quality of Life (QOL) [Short Form (SF)-36] in patients before and 6 months after receiving therapy. The HAM-D, SDAI, mHAQ and SF-36 scores after 6 months of therapy were measured as the outcomes. Results We analyzed 60 IFX patients and 53 MTX patients. The HAM-D scores significantly improved in both groups (p<0.001), but there was no significant difference in the effectiveness between the IFX and MTX therapies (p=0.792). The SDAI scores significantly improved in both groups after therapy (p<0.001), and IFX therapy was more effective than MTX therapy (p=0.004). The mHAQ and HAM-D scores also improved significantly in both groups after therapy (p<0.001), but no significant difference in the effectiveness between the IFX and MTX therapies was observed (p=0.272, 0.792). The scores of all 8 items of the SF-36 improved in both groups after therapy, but IFX therapy was more effective than MTX therapy in only 4 of the 8 items (p<0.05). Conclusion Both IFX and MTX therapy improved the clinical efficacy, ADL, QOL and depressive states. However, no significant differences regarding an improvement in the depressive states and ADL were observed between IFX therapy and MTX monotherapy.

Thermal Disparity between Fingers after Cold-water Immersion of Hands: A Useful Indicator of Disturbed Peripheral Circulation in Raynaud Phenomenon Patients.

OBJECTIVE: To devise an effective method to assess the peripheral circulation using an infrared thermographic analysis. METHODS: Sequential measurements of the skin temperature before and after cold-water immersion of the hands were analyzed by a thermographic examination in healthy controls and patients diagnosed to have Raynaud phenomenon (RP). The skin temperatures of the dorsum of all fingernail folds and the metacarpophalangeal (MCP) joints were measured at baseline. Then the hands were immersed in 10°C water for 10 s, and the skin temperatures were measured at 0, 3, 5, 10, 15, 20 and 30 min after immersion. The mean temperature, recovery rate and disparity (coefficient of variation) of the nail fold temperatures were calculated. The distal-dorsal difference (DDD) was calculated by subtracting the mean MCP temperature from the mean nail fold temperature. Receiver operating characteristic (ROC) curves were generated to compare these parameters in terms of their capability to differentiate patients with RP. RESULTS: Thirty-one RP patients and 25 controls were included in the study. The baseline nail fold temperature was significantly lower in RP patients than in the controls. The RP patients had a lower recovery rate, lower DDD and higher disparity than the controls. The disparity and DDD were negatively correlated (r=-0.63, p<0.01), whereas the recovery rate and DDD were positively correlated (r=0.91, p<0.01). The ROC curve analysis revealed that the disparity in nail fold temperature effectively differentiated RP patients from controls (area under the curve: recovery rate 0.72; disparity 0.88; DDD 0.79). CONCLUSION: The temperature disparity between fingers is a useful thermographic parameter for evaluating disturbed peripheral circulation in patients with Raynaud phenomenon.

Atypical Subacute Recurrence of Catastrophic Antiphospholipid Syndrome in a Japanese Female Patient.

Catastrophic antiphospholipid syndrome (CAPS) survivors rarely relapse. We herein report a case of a second CAPS episode with an unusual subacute course and no microangiopathic hemolytic anemia (MAHA), a common CAPS symptom. During the first episode, the 69-year-old woman responded well to high-dose glucocorticoids and plasma exchange. On relapse, these treatments plus rituximab were ineffective and she died of multi-organ failure and bacterial cholangitis. The absence of MAHA and a subacute course do not exclude a CAPS recurrence.

[A case of primary intestinal tuberculosis in which small intestine perforation developed].

We report herein on a case of the primary intestinal tuberculosis in which small intestine perforation developed. A 60-year-old man with congestive heart failure developed fever and sudden onset of abdominal pain while he was in the hospital. Computed tomography of the abdomen showed a large amount of free-air and the thickening of a part of the ileum. Perforation of the gastrointestinal tract was diagnosed, The patient underwent emergency exploratory laparotomy and a partial resection of the ileum was performed. The presence of nodules in the ileum suggested possible tuberculosis of the intestine. Pathologically caseating epithelioid granulomas were noted and the diagnosis of tuberculosis of the ileum was made although microbiologically tuberculous bacilli were not documented. The patient was successfully treated with antituberculosis chemotherapy. Although intestinal tuberculosis is a rare cause of intestinal perforation, it is important to include intestinal tuberculosis as one of the cases.
