First month prednisone dose predicts prednisone burden during the following 11†months: an observational study from the RELES cohort.

AIM: To study the influence of prednisone dose during the first month after systemic lupus erythematosus (SLE) diagnosis (prednisone-1) on glucocorticoid burden during the subsequent 11 months (prednisone-2-12). METHODS: 223 patients from the Registro Español de Lupus Eritematoso Sistémico inception cohort were studied. The cumulative dose of prednisone-1 and prednisone-2-12 were calculated and recoded into a four-level categorical variable: no prednisone, low dose (up to 7.5 mg/day), medium dose (up to 30 mg/day) and high dose (over 30 mg/day). The association between the cumulative prednisone-1 and prednisone-2-12 doses was tested. We analysed whether the four-level prednisone-1 categorical variable was an independent predictor of an average dose >7.5 mg/day of prednisone-2-12. Adjusting variables included age, immunosuppressives, antimalarials, methyl-prednisolone pulses, lupus nephritis and baseline SLE Disease Activity Index (SLEDAI). RESULTS: Within the first month, 113 patients (51%) did not receive any prednisone, 24 patients (11%) received average low doses, 46 patients (21%) received medium doses and 40 patients (18%) received high doses. There was a strong association between prednisone-1 and prednisone-2-12 dose categories (p<0.001). The cumulative prednisone-1 dose was directly associated with the cumulative prednisone-2-12 dose (p<0.001). Compared with patients on no prednisone, patients taking medium (adjusted OR 5.27, 95% CI 2.18 to 12.73) or high-dose prednisone-1 (adjusted OR 10.5, 95% CI 3.8 to 29.17) were more likely to receive prednisone-2-12 doses of >7.5 mg/day, while patients receiving low-dose prednisone-1 were not (adjusted OR 1.4, 95% CI 0. 0.38 to 5.2). If the analysis was restricted to the 158 patients with a baseline SLEDAI of ≥6, the model did not change. CONCLUSION: The dose of prednisone during the first month after the diagnosis of SLE is an independent predictor of prednisone burden during the following 11 months.

[Intolerance to hydroxychloroquine marketed in Spain (Dolquine) in patients with autoimmune conditions]. / Intolerancia a la hidroxicloroquina comercializada en España (Dolquine) en pacientes con patología autoinmune.

BASIS: A significant proportion of our patients has described to have problems from tolerance to Dolquine, a new presentation of hydroxychloroquine recently marketed in Spain, compared to Plaquenil. The objective was to know the tolerability and the adverse effects of this new presentation. PATIENTS AND METHOD: A cross-sectional multicenter study on 133 patients treated with Dolquine was conducted. RESULTS: Of the 133 patients (87% women; average age [AA]: 32.9 [15.4] years) who received Dolquine during an average period of 6.7 (1.4) months, 32 patients (24%) described to have more problems with this drug in comparison with other antimalarial. The adverse effects experienced were: bitter taste (62.4%), difficulty in swallowing the tablet (13.5%), dyspepsia (9.8%), nausea (7.5%), vomiting (1.5%), pruritus (1.5%), diarrhea (0.7%), and instability feeling (0.7%). The presence of gastrointestinal adverse effects was not related to the consumption of gastroerosive drugs, gastric protectors, or a high number of drugs. The attrition rate was 9.8%. Conclusions. Dolquine induces lower tolerance and more gastrointestinal adverse effects than Plaquenil, pointing out its bitter taste and the difficulty in swallowing it. Despite this higher intolerance there was not an increase in the attition rate from the antimalarial treatment in comparison to other series.

[Mesenteric lymph node cavitation: a rare complication of celiac disease in the adult]. / Cavitación ganlionar mesentérica: una rara complicación de la enfermedad celíaca del adulto.

A case of coeliac disease (CD) and mesenteric lymph node cavitation (MLNC) in a 42-years-old female is presented. The other cases reported in the literature are also reviewed. The most important ganglionar histological features are described and a pathogenic explanation is suggested.

[Microangiopathic hemolytic anemia associated with neoplasms: an analysis of 5 cases and a review of the literature]. / Anemia hemolítica microangiopática asociada a neoplasias: análisis de cinco casos y revisión de la literatura.

From January of 1990 to June of 1993 a diagnosis of microangiopathic hemolytic anemia (MHA) was made in 5 out off 121 new patients with malignant tumor. There were 3 females and 2 males, with a mean age of 57 yr (range: 43-75), and a primary tumor in stomach (n = 2), pancreas (n = 1) and of unknown origin (n = 2). In all cases histologic type was adenocarcinoma and diagnosis was obtained by marrow examination. Four patients developed a disseminated intravascular coagulation syndrome. Intravascular deposits of fibrin, intimal proliferation and tumoral microembolisms were noted in 2 cases. Patients did not received chemotherapy, and the median survival was 7 days (range: 3-61).

[Meningeal carcinomatosis. Review of 30 cases]. / Carcinomatosis meníngea. Revisión de 30 casos.

The clinical features of 30 patients with carcinomatous meningitis caused by solid tumors are reported. The most common originating sites of tumors were lung (12 cases) and breast (9 cases). Headache was the most common presenting symptom and there was involvement in more than one level of neuro-axis in 53% of cases. The CSF from the first lumbar puncture was abnormal in all cases; pleocytosis and an increased protein level in CSF were of great diagnostic value when a positive cytology was absent. Only three patients were treated with intrathecal chemotherapy, with a median survival of six weeks since the onset of symptoms.

[Reactive arthritis caused by Giardia lamblia in a patient with secretory IgA deficiency]. / Artrite reactiva por Giardia lamblia num doente com défice de IgA secretora.

The authors report a case of seronegative polyarthritis resistant to the anti-inflammatory therapy in a 16-year-old male with intermittent diarrhea. A stool examination showed the presence of cysts of Giardia lamblia and an immunological study detected a partial serum IgA deficiency, including its secretory fraction. Based on clinical, analytical and radiological findings and the clinical improvement after treatment with metronidazole, a diagnosis of reactive arthritis associated to chronic giardiasis was made. Authors make a brief review of the literature the regarding this case.

Hyperammonaemic encephalopathy as the presenting feature of IgD multiple myeloma.

We observed a case of hyperammonaemic encephalopathy in a patient without liver dysfunction which revealed meningeal involvement of IgD multiple myeloma. We have reviewed briefly the hyperammonaemic syndrome and we believe that this diagnosis has to be considered in differential diagnosis of encephalopathies in patients with multiple myeloma.
